Technical Field
[0001] This utility model relates to the field of anti-runaway technology, and more specifically, to an anti-runaway device for explosion-proof battery monorail cranes. Background Technology
[0002] During monorail operation, if slippage occurs, the vehicle may move uncontrollably and rapidly, posing a serious threat to personnel working near the track, such as collisions or crushing. Anti-slippage devices can effectively prevent slippage, thereby avoiding injury to personnel and ensuring the safety of workers.
[0003] Among the existing publicly available documents, patent publication number CN205472286U discloses a monorail crane anti-slippage protection device. This technology works by releasing air from the cylinder when the crane stops, restoring it to normal operation. The top block, under the elastic force of the spring, pushes upwards until it reaches the lower surface of the I-beam guide rail. Due to the friction between the top block and the lower surface of the I-beam rail, the crane will not move or slip. Even if the top block wears down and the crane slips, the top block will be stopped by the next stop, preventing a serious accident. When the crane is moving, the cylinder is vented, the cylinder shaft retracts, and the top block presses against the spring, moving downwards, allowing the crane to travel normally. However, this technology still has the following drawbacks.
[0004] When using the explosion-proof battery monorail anti-slip device, the monorail needs to be anti-slipped. After being lifted to the designated position, the anti-slipping operation can be performed, but it is difficult to achieve multi-tooth body embedding of the anti-slipping mechanism, resulting in poor stability. Therefore, the explosion-proof battery monorail anti-slipping device is needed. Utility Model Content

The multi-toothed locking assembly supports multiple anti-slipping tooth blocks 3 through inclined bars 2. The multiple anti-slipping tooth blocks 3 can achieve multi-tooth meshing and locking with toothed plates 4. The counterweight block 12 and counterweight reinforcement block 11 further enhance the anti-slipping effect. The specific structural configuration of the multi-toothed locking assembly is as follows.
[0021] In this embodiment, as shown in the appendix Figure 1 - Appendix Figure 3As shown, the inclined bar 2 is fixed to one side of the monorail 1, and the upper inclined surface of the inclined bar 2 is provided with a multi-tooth groove locking assembly; the multi-tooth groove locking assembly includes multiple anti-slip tooth blocks 3, tooth plates 4, push rods 5, electric cylinders 6, connecting sliders 7, rollers 8, support shafts 9, and support blocks 10; multiple anti-slip tooth blocks 3 are all fixed on the upper inclined surface of the inclined bar 2, the tooth plates 4 are located above the anti-slip tooth blocks 3, the push rods 5 are fixed on the upper inclined surface of the tooth plates 4, the electric cylinders 6 are fixedly connected to the top of the push rods 5, the connecting sliders 7 are slidably located on the outer wall of the push rods 5, the electric cylinders 6 and the connecting sliders 7 are fixedly connected, the connecting sliders 7 are slidably connected to the monorail 1, and the rollers 8 are rotatably connected inside the connecting sliders 7.

The support block 10 is fixedly connected to the sleeve slider 7. Multiple anti-slip tooth blocks 3 are arranged equidistantly from bottom to top, with a gap between adjacent anti-slip tooth blocks 3. The electric cylinder 6 is slidably connected to the monorail 1, and there is a gap between the toothed plate 4 and the monorail 1. There is a gap between the support block 10 and the roller body 8. The vertical cross-section of the support shaft 9 is circular, and the vertical cross-section of the roller body 8 is annular.
[0023] In this embodiment, as shown in the appendix Figure 4 As shown, a reinforcing block 11 is fixedly connected to the upper inclined surface of the inclined bar 2 near its bottom end; a counterweight block 12 is fixedly connected to the upper surface of the reinforcing block 11, and a connecting block 13 is fixedly connected to the upper surface of the counterweight block 12, so that the counterweight block 12 can be counterweighted by the connecting block 13, the counterweight block 12 can counterweight the reinforcing block 11, and the reinforcing block 11 can counterweight the bottom position of the upper inclined surface of the inclined bar 2, thus improving the anti-slip effect.
[0024] When using the explosion-proof battery monorail hoist anti-slip device, the bottom of the crane needs to be fixedly installed on the upper inclined surface of the connecting slider 7 during the explosion-proof battery monorail hoisting process. The crane drives the connecting slider 7 to tilt upwards, and the connecting slider 7 tilts upwards along the outer wall of the monorail 1. The connecting slider 7 also drives the electric cylinder 6 to tilt upwards, and the electric cylinder 6 drives the push rod 5 to tilt the toothed plate 4 upwards. In this way, the toothed plate 4 can tilt upwards to the designated position. The connecting slider 7 also drives the support block 10 to tilt upwards, and the support block 10 drives the support shaft 9 to tilt upwards. The support shaft 9 drives the outer wall of the roller 8 to roll. The roller 8 rolls on the inclined surface of the monorail 1. When the connecting slider 7 moves to the designated position, the electric cylinder 6 is activated. The electric cylinder 6 pushes the push rod 5 down, and the push rod 5 drives the toothed plate 4 down. The toothed plate 4 presses against multiple anti-slip toothed blocks 3.

The outer wall of the guide post 15 and the inner wall of the sleeve block 14 are both smooth surfaces, and the cross-sectional shape of the slip ring 16 is annular.
[0026] When this explosion-proof battery monorail anti-slip device is in use, the tilting bar 2 tilts and moves downward, which in turn causes the base block 18 to tilt and move downward. The base block 18 then causes the guide column 15 to tilt and move downward. The guide column 15 tilts and moves downward along the inner wall of the slip ring 16 and the inner wall of the sleeve block 14. At the same time, the counterweight block 17 counterweights the guide column 15 as it tilts and moves downward. In this way, the tilting bar 2 can stably engage and lock with the multiple anti-slip tooth blocks 3 on the tilting bar 2, resulting in better anti-slip stability.
