For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0021] The present application embodiment provides a braking device for a material car winch, such as Figures 1 to 4 As shown. The braking device of the material car winch includes a first power member 1, a second power member 10, a first reducer 2, a second reducer 11, a first brake 4, a second brake 12 and two brake discs 3. The first power member 1, the first reducer 2, the first brake 4, the second brake 12, the second reducer 11 and the second power member 10 are fixed to the base platform 8 and are arranged at intervals along the length direction of the base platform 8. The two ends of the drum 9 are respectively connected to the first output end of the first reducer 2 and the first output end of the second reducer 11 through two bearing seats 5. The two brake discs 3 are respectively connected to the second output end of the first reducer 2 and the second output end of the second reducer 11, and are respectively located on the inner side of the first brake 4 and the second brake 12. When the brake disc 3 needs to be locked, the first brake 4 and the second brake 12 simultaneously lock the corresponding brake disc 3 to ensure rapid braking during high-speed operation, stable and reliable braking, and not easy to slip. The first brake 4 and the second brake 12 are used to lock or release the corresponding brake disc 3. The output end of the first power member 1 and the output end of the second power member 10 are connected to the input end of the first reducer 2 and the input end of the second reducer 11 respectively.

[0022] Specifically, the first power member 1 and the second power member 10 of the embodiment of the present application are both motors. The first output end and the second output end of the first reducer 2 are located on the same side; the first output end and the second output end of the second reducer 11 are located on the same side.

[0023] It should be noted that when the drum 9 needs to work, the first power member 1 and the second power member 10 respectively drive the first reducer 2 and the second reducer 11 to rotate. At this time, the first brake 4 and the second brake 12 loosen the brake disc 3 on the second output end of the first reducer 2 and the brake disc 3 on the first output end of the second reducer 11, and the first output end of the first reducer 2 and the first output end of the second reducer 11 drive the drum 9 to rotate; when the drum 9 needs to stop, the first brake 4 and the second brake 12 respectively lock the brake disc 3 on the second output end of the first reducer 2 and the brake disc 3 on the second output end of the second reducer 11 to achieve deceleration and parking of the material car. When the brake disc 3 is worn and needs to be removed, the maintenance personnel only need to remove the brake disc 3 The bolts of the bolt avoid removing the first power member 1 and the second power member 10, which improves the work efficiency of the maintenance personnel. Therefore, the brake device of the material car winch in the embodiment of the present application has a simple structure and is easy to disassemble and assemble.

[0024] In the embodiment of the present application, the braking device of the material car winch also includes two first couplings 6 and two second couplings 7.

[0025] It should be noted that the first coupling 6 and the second coupling 7 have the functions of buffering, reducing vibration and improving the dynamic performance of the shaft system.

[0026] In the embodiment of the present application, the brake disc 3 is made of carbon steel.

[0027] It should be noted that the brake wheel of the prior art is made of cast steel, the interior is not processed, the dynamic balance accuracy is low, and the high-speed operation generates centrifugal force, resulting in the overall equipment running unsteadily and making a lot of noise. The brake disc of the embodiment of the present application is made of carbon steel, which is finely processed, has high dynamic balance accuracy, generates less centrifugal force when running at high speed, and the equipment runs smoothly with little noise.

[0028] In the embodiment of the present application, the first brake 4 and the second brake 12 are both electric hydraulic disc brakes. The brake in the prior art is an electric hydraulic drum brake. The electric hydraulic disc brake has better high temperature resistance and more stable braking effect under high load.

[0029] In the embodiment of the present application, a plurality of brake grooves are provided on the side wall of the brake disc 3. The brake caliper of the first brake 4 and the brake caliper of the second brake 12 are used to be inserted into the corresponding brake grooves of the brake disc 3 or to be away from the corresponding brake grooves of the brake disc 3.

[0030] Furthermore, the brake disc 3 of the embodiment of the present application is provided with a plurality of heat dissipation holes, which accelerates the ventilation effect, improves the braking effect of the overall structure, and prolongs the service life of the brake disc.

[0031] In the embodiment of the present application, the first power member 1 and the second power member 10 are symmetrically arranged, the first reducer 2 and the second reducer 11 are symmetrically arranged, and the first brake 4 and the second brake 12 are symmetrically arranged, which improves the braking effect of the overall structure.

[0033] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present application.
