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 spring swelling device.
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 spring, 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 the easier wearing and tearing of blade.
Summary of the invention:
The object of the present invention is to provide a kind of spring swelling device, described this spring swelling device will solve the fast technical matters of expanding force decay when swelling device adopts rubber spring in the prior art.
This spring swelling device of the present invention is by support, blade installation shaft and spring 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 spring housing 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.Spring is connected as a single entity blade installation shaft and connecting rod with set pin when free state.Then make spring-compressed with spanner turn pressure adjusting nut, and screw rod moves up under the effect of spring 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 spring 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 spring 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 spring that enough large power is provided, the size of power can be regulated by the amount of compression of spring, 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 spring swelling device of the present invention looks scheme drawing.
Fig. 2 is that scheme drawing is looked on the left side of a kind of spring swelling device of the present invention.
The specific embodiment:
As depicted in figs. 1 and 2, a kind of spring swelling device of the present invention, by support 16, blade installation shaft 9 and spring 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 2, described spring 4 is set on the screw rod 6, and between support 16 upper sides and pressure adjusting nut 2, 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.
