Description

Technical Field

[0001] The present invention relates to the field of mine safety equipment, and particularly to a quick boot-unfastening mechanism for a belt-breaking catcher. Background Art

[0002] In many industries such as coal mines, mines, and cement plants, belt conveyors are widely used as transportation equipment. With the development of science and technology and the economy, belt conveyors have gradually developed towards the direction of long distance, large transportation volume, high power, large transportation angle, and high-speed transportation. However, with the wide application of conveyors in coal mines underground, the phenomenon of belt-breaking accidents is also increasing continuously. Especially for the conveyor belts with large inclination angles, long distances, and large transportation volumes, during the unstable stages of starting and braking, the traction force and inertial force applied to the conveyor belt by the driving device will propagate, superimpose, and reflect in the belt at a certain wave speed. Coupled with the influence of other factors, variable stress changes will be caused in the conveyor belt. If the instantaneous peak stress exceeds the allowable value, it will damage the conveyor belt and cause it to break. When a belt break occurs, both the heavy and empty belts will slide downward. The descending materials and belts will bury and damage equipment, block the roadway, resulting in long-term production stoppages, significant economic losses, and even casualties. Therefore, setting up a belt-breaking catching device has very important practical significance. When an accident occurs to the belt conveyor, the tension of the conveyor belt will suddenly decrease, the conveyor belt will become loose and slide downward, and the upper and lower supporting rollers of the catcher will lose their supporting force. The upper catching frame will rotate upward under the action of the torsion spring and cooperate with the upper cross beam to catch the load-bearing conveyor belt, and the lower catching frame will rotate downward under the action of gravity and cooperate with the lower cross beam to catch the return conveyor belt. After the catching action is completed, it is necessary to relieve the force on the upper and lower catching frames and restore them to their original positions. At this time, it is often not easy to reset the catching frame only by manpower. Therefore, a quick boot-unfastening auxiliary device is needed. Summary of the Invention

[0003] To solve the above technical problems, the present invention provides a quick boot-unfastening mechanism for a belt-breaking catcher, which includes a first side plate, a second side plate, a connecting bolt for connecting the first side plate and the second side plate, an adjusting screw rod and an adjusting block arranged on the first side plate. The adjusting block is installed on the catching frame of the belt-breaking catcher, and the position of the adjusting screw rod corresponds to that of the adjusting block. When the adjusting screw rod is rotated, the catching frame of the belt-breaking catcher is pushed by pushing the adjusting block to move away from the cross beam of the belt-breaking catcher, thereby completing the reset of the belt-breaking catcher.

[0004] Further, two holes for installing the connecting bolt are arranged at the upper part of the first side plate, respectively for installing the connecting bolt, and a plurality of holes for installing the adjusting screw rod are arranged at the lower part of the first side plate.

[0005] Further, holes for installing connecting bolts are provided on the second side plate. There are two connecting bolts, and the connecting bolts form a square lock through the holes on the first side plate and the second side plate and are installed and fixed on the cross beam of the tape-breaking arrester.

[0006] Further, one end of the adjusting screw rod is a full-threaded part installed in a hole at the lower part of the first side plate, and the other end is a smooth cylinder with a spherical top.

[0007] Further, an arc-shaped groove is provided at one end of the adjusting block, and the arc-shaped groove cooperates with the spherical top of the adjusting screw rod in a curved surface contact.

Multiple holes for installing the adjusting screw 4 are arranged at the lower part of the first side plate 1. Holes for installing the connecting bolt 3 are arranged on the second side plate 2. There are two connecting bolts 3. The connecting bolts 3 form a square lock through the holes on the first side plate 1 and the second side plate 2 and are installed and fixed on the cross beam 6 of the broken - belt catcher. Spring washers and flat washers are installed on the connecting bolts 3, and double nuts are used for tightening to further achieve the purpose of preventing loosening. In this embodiment, multiple installation holes are arranged on the first side plate 1 for installing the adjusting screw 4, which is beneficial for applying different models of broken - belt catchers.

[0023] In the embodiment, one end of the adjusting screw 4 is a full-threaded part installed in a hole at the lower part of the first side plate 1, and the other end is designed as a smooth cylinder with a spherical top. The full-threaded part at one end of the adjusting screw 4 is beneficial to providing a larger adjustment range for the adjusting screw 4 when the boot-unfastening action is completed; the design of the other end as a smooth cylinder with a spherical top is beneficial to the slight rotation of the adjusting screw 4 in the groove of the adjusting block 5 and the cooperation to complete the boot-unfastening action.
