Problems solved by technology
Belt breakage is likely to occur due to corrosion, breakage of the steel wire rope core, or belt vulcanization. At present, the breakage mostly occurs near the driving drum and on the load-carrying belt with a large slope. Once a breakage occurs, the breakage will slide down. Destroy the tape rack, damage the equipment, block the transportation channel, and cause major economic losses due to long-term production stoppages, and there are also potential safety hazards
In the existing belt broken belt catcher, when the belt breaks, the belt slips backwards, driving the supporting roller to reverse, and the brake blocks on both sides are raised along the slideways on both sides through the transmission mechanism, and the broken belt is pressed against both sides of the frame On the upper brake block, the structure is complex and there are many transmission parts. During the process of catching the broken belt, both ends of the belt are clamped and braked, and the force on the belt is uneven, which is likely to cause a second break and cause the capture to fail.

Embodiment Construction
[0025] Figure 1~6 It is the best embodiment of the present invention, below in conjunction with attached Figure 1~6 The present invention will be further described.
[0026] refer to Figure 1~2 A crossbeam 2 is arranged horizontally above the frame 1, and a roller shaft 5 is horizontally arranged below the crossbeam 2. The roller shaft 5 is fixed on the frame 1 and the axis of the roller shaft 5 is parallel to the length direction of the crossbeam 2. The brake idler roller 4 is rotated and set at The left side of the roller shaft 5 and the right side of the roller shaft 5 are provided with a driving idler 3, and the end of the driving idler 3 close to the brake idler 4 is welded with a ratchet mounting plate 8, and the ratchet 6 is welded on the ratchet mounting plate 8 close to the brake. One side of the idler 4, and the ratchet 6 is located in the driving idler 3, the ratchet 6 is coaxial with the roller shaft 5, and the end of the braking idler 4 close to the driving i...

The invention relates to a broken belt trap, and belongs to the field of conveying equipment for mining. The broken belt trap is characterized by comprising a rack (1), a belt pressing device, a driving support roller (3), a braking support roller (4), a back stop device and a releasing mechanism; and a cross beam (2) is arranged on the rack (1), the belt pressing device is rotatably arranged on the rack (1) and is located below the cross beam (2), the belt pressing device comprises a belt pressing support roller (16), the driving support roller (3) is located below the cross beam (2), the releasing mechanism is arranged between the braking support roller (4) and the belt pressing device, and the driving support roller (3) is connected with the braking support roller (4) by virtue of the back stop device. The driving support roller (3) is driven to reverse by a broken belt, the braking support roller (4) is driven to rotate by the back stop device, the belt pressing support roller (16) is released by the releasing mechanism, and the belt pressing support roller (16) rotates around the rack (1) so as to press the belt on the cross beam (2), so that the belt is braked after being broken, and the safety of equipment and operating workers is protected.
Description
technical field [0001] A broken belt catcher belongs to the field of mine conveying equipment. Background technique [0002] The upper belt conveyor has the characteristics of large inclination angle, long distance and large load, and is the main equipment for the production and transportation of raw coal in coal mines. Belt breakage is likely to occur due to corrosion, breakage of the steel wire rope core, or belt vulcanization. At present, the breakage mostly occurs near the driving drum and on the load-carrying belt with a large slope. Once a breakage occurs, the breakage will slide down. Destroy the tape rack, damage the equipment, block the transportation channel, and cause major economic losses due to long-term production stoppages, and there are also potential safety hazards. In the existing belt broken belt catcher, when the belt breaks, the belt slips backwards, driving the supporting roller to reverse, and the brake blocks on both sides are raised along the slidew...
