Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of TBM continuous belt transmission accessories, in particular to a guide bracket for preventing a tensioning trolley from tilting up. Background Art
[0002] The continuous belt conveyor used in conjunction with the TBM roadheader has a variable frequency tensioner that pulls the tensioning wire rope to tighten the 10 layers of belts in the belt storage bin and releases the belts in the belt storage bin in the direction of the belt force. However, because the arm distance between the tensioning wire rope and the rear wheel of the tensioning trolley is too small, the torque generated is much smaller than the sum of the torques of the 10 layers of belts on the rear wheel of the tensioning trolley. The original design of the anti-tilting device for the tensioning trolley has low strength, is easily deformed and fails, and has high friction.
[0003] Therefore, during the belt tensioning process, the front end of the tensioning trolley is prone to tilt up, which can easily cause the front and rear wheels of the tensioning trolley to derail. In order to solve this problem, we have designed a guide bracket to prevent the tensioning trolley from tilting up, which can effectively prevent the above phenomenon from occurring. Utility Model Content
[0004] In view of the defects in the prior art, the utility model provides a guide bracket for preventing the tensioning trolley from tilting up, so as to solve the problem that the front end of the tensioning trolley is easily tilted up during the tensioning process of the belt, so as to ensure safe production.
[0005] In the first aspect, the utility model provides a guide bracket for preventing the tensioning trolley from tilting, comprising: a vertical support frame, a transverse support frame, an oblique support frame, a guide assembly and an adjustment assembly; the guide assembly is connected to the vertical support frame through the adjustment assembly; the transverse support frame is fixedly mounted on the vertical support frame, one end of the oblique support frame is connected to the transverse support, and the other end of the oblique support frame is connected to the tensioning trolley; one end of the vertical support frame is arranged on the tensioning trolley; wherein, the guide assembly comprises a guide wheel; the adjustment assembly comprises an adjustment pad and a connecting adjustment piece, the guide wheel is detachably mounted on the adjustment pad, and the adjustment pad is detachably connected to the vertical support frame through the connecting adjustment piece.
[0006] Furthermore, the guide assembly also includes a guide shaft and a wheel frame plate; the wheel frame plate is detachably connected to the adjustment pad, the guide shaft is detachably installed in the wheel frame plate, and the guide wheel is rotatably installed on the guide shaft. In actual use, this design effectively realizes the installation and use of the guide wheel, and the overall structural design is reasonable and easy to operate.
[0007] Furthermore, the adjustment pad has at least one mounting hole, and the wheel frame plate has at least one connection hole; the connection adjustment member includes a bolt and a nut, and the bolt passes through the connection hole and the mounting hole, extends outward, and is detachably connected to the nut. In actual use, the purpose of this design is to achieve adjustment, and the installation method of the nut and bolt adopted can greatly reduce the design cost, while also ensuring the connection strength.
[0008] Furthermore, one end of the vertical support frame is arranged at one end of the tensioning trolley and is located in the front wheel direction of the tensioning trolley. In actual use, this design direction enables the guide wheel on the vertical support frame to press against the bottom surface of the H-shaped steel once the front end of the tensioning trolley is tilted again, and moves along the lower track with the tensioning trolley in the direction of the belt force.
[0009] Furthermore, there is a gap between the adjustment pad and the wheel frame plate, and the gap between the adjustment pad and the wheel frame plate is adjusted by rotating the nut. In actual design, the purpose of this design is to facilitate adjustment. At the same time, the gap also provides overload protection for the guide assembly and achieves a buffering effect.
[0010] Furthermore, the horizontal support frame is welded to the vertical support frame, and the horizontal support frame is welded to the oblique support frame. In actual use, this method greatly ensures the overall connection strength.
[0011] It can be seen from the above technical solution that the guide bracket for preventing the tensioning trolley from tilting provided by the utility model has the following beneficial effects:
[0012] (1) In actual use, this design replaces the original bottom anti-tilting solution. The original method is to use two relatively arranged half-shell tracks to restrain the tilting of the tensioning trolley. Compared with this application, this method, on the one hand, concentrates more load of the tensioning trolley at the bottom, and the impact generated will cause the half-shell track to bend and deform quickly; and the half-shell track is installed as a whole, once replaced, the actual cost is increased. On the other hand, the bottom anti-tilting setting cannot be adjusted, which accelerates the bending and deformation of the half-shell track.
[0013] (2) The present application has a simple structure, is easy to replace, is convenient to adjust, and has easily accessible accessories. In addition, during maintenance and installation, there is no need to replace the tensioning trolley as a whole. Therefore, the device is suitable for industry promotion.
