Abstract
The invention discloses an airbag tensioner, which consists of a bracket, a blade mounting shaft and an airbag. A through hole is formed on an upper side of the bracket, and a screw is arranged in the through hole. A pressure adjusting nut is arranged at an upper end of the screw, and the airbag is sleeved on the screw and positioned between an upper side face of the bracket and the pressure adjusting nut. A lower end of the screw extends into the bracket, and is connected with a screw barrel. A pin shaft is arranged in the screw barrel and penetrates a waist-type guide slot in one end of a connecting rod. One end of the blade mounting shaft is connected with the side face of the bracket through a bearing, extends into the bracket, and is connected with the other end of the connecting rod through a fixing pin. By using the airbag and a lever mechanism to continuously provide pressure for a sweeper blade, the airbag tensioner can provide constant tensioning force, has convenient adjustment, and guarantees that the blade is attached to a leather belt tightly enough. The airbag has good creep resistance, is not easy to age, and does not cause environmental pollution.
Description
Technical field:
The present invention relates to mechanical field, relate in particular to the attending device of Belt Conveying machinery, particularly a kind of airbag tensioner.
Background technology:
In the prior art, the clearing apparatus of coal mine conveying belt is made of blade and swelling device.Blade is used for striking off the foreign material on the load-transfer device, and swelling device keeps blade to the pressure of load-transfer device.Swelling device uses rubber pneumatic bag, and still, the rubber creep-resistant property is poor, easily aging, and can cause environmental pollution, the expanding force decay that provides is very fast, blade and belt adhesive force are inadequate after using a period of time, cause cleaning unclean, and blade more easily wear and tear.
Summary of the invention:
The object of the present invention is to provide a kind of airbag tensioner, described this airbag tensioner will solve the fast technical matters of expanding force decay when swelling device adopts rubber pneumatic bag in the prior art.
This airbag tensioner of the present invention is by support, blade installation shaft and air bag consist of, wherein, described support upside is provided with through hole, be provided with a screw rod in the described through hole, the upper end of described screw rod is provided with a pressure adjusting nut, described Air sac cover is located on the screw rod, and between support upper side and pressure adjusting nut, the lower end of screw rod extends in the support, the lower end of screw rod is connected with a screw sleeve, be provided with a bearing pin in the described screw sleeve, described bearing pin passes the interior waist type guide groove of an end of a connecting rod, one end of described blade installation shaft is connected with the side of support by bearing, this end of blade installation shaft extends in the support, and the other end of described connecting rod is connected with this end of blade installation shaft by set pin.
Further, described support is made of channel-section steel.
Further, be provided with bolt of rear end plate on the described support.
Further, the downside of described support is connected with dowel bolt, and described dowel bolt vertically passes the interior screw of downside of support, is provided with lock nut on the dowel bolt.
Working process of the present invention is: support is connected with the load-transfer device frame by bolt of rear end plate, first bolt of rear end plate is unscrewed, and then twists dowel bolt, support is moved up, determine after the location-appropriate, tighten lock nut dowel bolt is locked, tighten again bolt of rear end plate with fixed support.Air bag is connected as a single entity blade installation shaft and connecting rod with set pin when relaxed state.Then make the air bag compression with spanner turn pressure adjusting nut, and screw rod moves up under the effect of air bag and pressure adjusting nut, by band cutting blade installation shaft rotation under the effect of screw sleeve and connecting rod and set pin, thereby provide expanding force for the blade on the blade installation shaft.Because connecting rod is provided with waist type guide groove at the connecting portion of itself and screw sleeve, so screw rod can move up and down.Treat to tighten the pressure adjusting nut after the expanding force location positioning.
The present invention and prior art contrast, and its effect is actively with obvious.The present invention utilizes air bag and leverage to continue to provide pressure to sweeper blade, and comparatively constant expanding force can be provided, and guarantees that the applying of blade and belt is enough tight.The creep-resistant property of air bag is good, is difficult for wearing out, and can not cause environmental pollution.Only need very little power to turn the pressure adjusting nut with spanner and just can make air bag that enough large power is provided, the size of power can be regulated by the amount of compression of air bag, and the size of amount of compression can be weighed by a scale, therefore regulates very convenient.
Description of drawings:
Fig. 1 is that the master of a kind of airbag tensioner of the present invention looks schematic diagram.
Fig. 2 is that schematic diagram is looked on the left side of a kind of airbag tensioner of the present invention.
The specific embodiment:
As depicted in figs. 1 and 2, a kind of airbag tensioner of the present invention, by support 16, blade installation shaft 9 and air bag 4 consist of, wherein, described support 16 upsides are provided with through hole, be provided with a screw rod 6 in the described through hole, the upper end of described screw rod 6 is provided with a pressure adjusting nut 3, described air bag 4 is set on the screw rod 6, and between support 16 upper sides and pressure adjusting nut 3, the lower end of screw rod 6 extends in the support 16, the lower end of screw rod 6 is connected with a screw sleeve 7, be provided with a bearing pin 13 in the described screw sleeve 7, described bearing pin 13 passes the interior waist type guide groove of an end of a connecting rod 8, one end of described blade installation shaft 9 is connected by the side of bearing with support 16, this end of blade installation shaft 9 extends in the support 16, and the other end of described connecting rod 8 is connected with this end of blade installation shaft 9 by set pin 10.
Further, described support 16 is made of channel-section steel 15.
Further, be provided with bolt of rear end plate 5 on the described support 16.
Further, the downside of described support 16 is connected with dowel bolt 12, and described dowel bolt vertically passes the interior screw of downside of support 16, is provided with lock nut 11 on the dowel bolt.
Working process of the present invention is: support 16 is connected with the load-transfer device frame by bolt of rear end plate 5, first bolt of rear end plate 5 is unscrewed, then twist dowel bolt 12, support 16 is moved up, determine after the location-appropriate, tighten lock nut 11 with dowel bolt 12 lockings, tighten again bolt of rear end plate 5 with fixed support 16.Air bag 4 is connected as a single entity blade installation shaft 9 and connecting rod 8 with set pin 10 when free state.Then make air bag 4 compressions with spanner turn pressure adjusting nut 3, and screw rod 6 moves up under the effect of air bag 4 and pressure adjusting nut 3, by band cutting blade installation shaft 9 rotations under the effect of screw sleeve 7 and connecting rod 8 and set pin, thereby provide expanding force for the blade on the blade installation shaft 9.Because connecting rod 8 is provided with waist type guide groove at the connecting portion of itself and screw sleeve 7, so screw rod 6 can move up and down.Treat to tighten pressure adjusting nut 3 after the expanding force location positioning.
