The surface of the slide bar 5 is sleeved with a spring 13, and one end of the spring 13 is welded to the inner wall of the slide groove 12, and the other end of the spring 13 is welded to the bottom of the slide sleeve 11. Through the arrangement of the spring 13, the slide bar 5 is limited in the inner cavity of the fixed sleeve 4 to avoid that when there is no need to brake the front wheel 102, the slide bar 5 can drive the arc brake pad 6 to separate from the surface of the wheel 102 under the elastic force of the spring 13.

[0025] Embodiment 2:

[0026] Figure 1-4The utility model shows an inclined shaft lifting brake mechanism of an embodiment of the utility model, which includes protective sleeves 2 welded to the rear sides of both sides of the lifting vehicle 1: the lifting vehicle 1 includes a frame 101 and a bucket 103, wheels 102 are installed at the front and rear of both sides of the bottom of the frame 101, a bucket 103 is fixedly installed on the top of the frame 101, a traction frame 104 is welded on the top of the frame 101, the inner cavity of the protective sleeve 2 is slidably connected to a cylinder 3, the front sides of both sides of the frame 101 are welded with fixed sleeves 4, the inner cavity of the fixed sleeve 4 is slidably connected to a slide rod 5, the top of the slide rod 5 penetrates to the top of the fixed sleeve 4, and the output of the cylinder 3 is connected to the inner cavity of the protective sleeve 2. An arc-shaped brake pad 6 is fixedly installed at the output end and the bottom of the slide bar 5. The inner cavity of the arc-shaped brake pad 6 fits with the surface of the wheel 102. The arc-shaped brake pad 6 is a copper-steel alloy metal brake pad. Two mounting plates 8 are welded to the front sides of both sides of the truck bucket 103. An eccentric wheel assembly 9 is rotatably connected between the two mounting plates 8. The rear end of the eccentric wheel assembly 9 is provided with a motor 10 fixedly installed on one side of the truck bucket 103.

A sliding sleeve 11 is welded on the surface of the slide bar 5, and a sliding groove 12 adapted to the sliding sleeve 11 is provided inside the fixed sleeve 4.

[0027] Working principle: When the utility model is used, the user programs the two sets of brake mechanisms into two systems respectively, so that the two sets of systems can be started simultaneously or unidirectionally. If the front brake mechanism is started, the motor 10 will be operated, so that the eccentric wheel assembly 9 rotates between the two mounting plates 8, and then the slide bar 5 is squeezed. At this time, the slide bar 5 will slide downward in the inner cavity of the fixing sleeve 4, so that the front arc brake pad 6 brakes the front wheel 102;

[0028] If the rear brake mechanism is activated, the cylinder 3 slides downward in the inner cavity of the protective sleeve 2, and then the rear arc-shaped brake pad 6 moves downward to brake the rear wheel 102. The method of adding two different brake mechanisms at the front and rear of the hoisting vehicle plays a double insurance role in the braking of the inclined shaft hoisting, and effectively avoids the situation where the hoisting vehicle quickly reverses and derails after the wire rope breaks.

[0029] To sum up: the inclined shaft hoisting brake mechanism, through the coordinated use of the protective sleeve 2, the cylinder 3 and the arc-shaped brake pad 6, brakes the rear wheel 102. Through the setting of the motor 10, the eccentric wheel assembly 9 is driven to rotate between the two mounting plates 8, thereby squeezing the slide rod 5. Through the coordinated use of the fixed sleeve 4, the slide rod 5 and the arc-shaped brake pad 6, the front wheel 102 is braked, thereby achieving the double insurance effect of the inclined shaft hoisting, and effectively avoiding the derailment of the hoisting vehicle due to rapid reverse after the wire rope breaks.
