[0018] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description of this application is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

[0019] Hydraulic supports are the core equipment of fully mechanized mining faces. They feature active support, automatic support movement, and collaborative operation with other fully mechanized mining equipment (coal mining machine, scraper conveyor).

[0020] In related technologies, a reversible foot pedal is hinged to the base of the hydraulic support to improve the safety of the working surface and facilitate maintenance personnel to inspect and repair the pushing mechanism.

[0021] However, the accidental closure of the foot pedal can increase the probability of injury to maintenance personnel.

[0022] Based on the above considerations, this application provides a hydraulic support foot pedal structure that can solve the problem in the prior art where the probability of injury to maintenance personnel increases due to accidental closure of the foot pedal.

[0023] The specific implementation of this application will be described in detail below with reference to specific embodiments.

[0024] Please see Figures 1-2The embodiments of this application provide a hydraulic support foot pedal structure 10, including a foot pedal 11 hinged to a base 20. The foot pedal 11 is hinged to a telescopic mechanism 12 on the base 20. A pin 13 is provided on the foot pedal 11. The pin 13 is configured to be able to engage between the side plate 21 and the foot pedal 11 after the foot pedal 11 is flipped to the outside of the side plate 21 of the base 20.

[0025] Foot pedal 11 refers to the main structural part of the hydraulic support foot pedal structure 10. It is mounted on the base 20 and can be flipped. The first end of the foot pedal 11 is hinged to the outer side plate 21 of the base 20, and the second end of the foot pedal 11 is overlapped to the inner side plate 21 of the base 20.

[0026] When the second end of the foot pedal 11 is attached to the inner side plate 21 of the base 20, the foot pedal 11 is in a horizontal state, which is also the closed state of the foot pedal 11.

[0027] When the second end of the foot pedal 11 is flipped outward to the outside of the side plate 21 located outside the base 20, the foot pedal 11 is in a vertical state, which is also the open state of the foot pedal 11.

[0028] The telescopic mechanism 12 refers to the drive structure that drives the foot pedal 11 to flip. Its fixed end is hinged to the side plate 21 on the inner side of the base 20, and its movable end is hinged to the bottom of the foot pedal 11.

[0029] When the telescopic mechanism 12 extends, it causes the foot pedal 11 to flip outward; when the telescopic mechanism 12 retracts, it causes the foot pedal 11 to flip inward or outward.

[0030] The telescopic mechanism 12 may be, but is not limited to, a hydraulic cylinder.

[0031] Pin 13 refers to the blocking structure that restricts the foot pedal 11 from turning inward. It is inserted into the foot pedal 11 and can extend outward from the foot pedal 11.

[0032] When the telescopic mechanism 12 pushes the foot pedal 11 to flip outward to a vertical position, the pin 13 can be moved outward to engage between the foot pedal 11 and the side plate 21 of the base 20. At this time, the pin 13 prevents the foot pedal 11 from flipping inward, thus preventing the foot pedal 11 from flipping inward due to accidental circumstances and reducing the probability of injury to maintenance personnel due to accidental closure of the foot pedal 11.

[0033] The hydraulic support foot pedal structure 10 provided in this application embodiment can prevent the foot pedal 11 from closing inward by engaging a pin 13 between the outwardly opening foot pedal 11 and the side plate 21 of the base 20. Compared with the prior art, this can reduce the probability of maintenance personnel being injured due to the accidental closing of the foot pedal 11.

[0034] Please see Figures 1-2 In some embodiments, the foot pedal 11 includes a frame 111 and a pedal 112.

[0035] The pedal 112 is welded to the mesh frame 111. One end of the frame 111 is hinged to the side plate 21 on the outside of the base 20. The movable end of the telescopic mechanism 12 is hinged to the bottom surface of the pedal 112.

[0036] A support leg 1111 is formed on the frame 111. The support leg 1111 is used to abut against the inner side plate 21 of the base 20 to keep the pedal 112 horizontal in the closed state.

[0037] A gasket 1112 is fixed to the outrigger 1111. The gasket 1112 may be, but is not limited to, a rubber gasket. The gasket 1112 is used to prevent the outrigger 1111 from directly contacting the side plate 21. The gasket 1112 has a cushioning effect and can prevent damage caused by rigid impact.

[0038] Please see Figures 1-2 In some embodiments, the frame 111 and the pedal 112 are provided with corresponding shaft holes 1113 for the pin 13 to pass through.

[0039] The pin 13 passes through the shaft hole 1113 on the frame 111 and the pedal 112. The positioning effect of the two shaft holes 1113 can ensure the stability of the pin 13 installation.

[0040] The pin 13 has multiple positioning holes 132 for B-shaped pins 131 to pass through, and the positioning holes 132 are arranged at intervals along the axial direction of the pin 13 and along the diameter direction of the pin 13.

[0041] The B-shaped pin 131 is inserted into the positioning hole 132. By utilizing the ground connection between the B-shaped pin 131 and the end face of the shaft hole 1113, the pin shaft 132 can be limited.

[0042] Among them, an end cap 133 is integrally formed on the inner end of the pin 13. The outer diameter of the end cap 133 is larger than the diameter of the shaft hole 1113. The end cap 133 can prevent the pin 13 from completely disengaging from the shaft hole 1113 during the outward movement.

[0043] Optionally, the pin 13 is parallel to the hinge axis of the foot pedal 11.

[0044] The hydraulic support foot pedal structure 10 provided in this application embodiment can prevent the foot pedal 11 from closing inward by engaging a pin 13 between the outwardly opening foot pedal 11 and the side plate 21 of the base 20. Compared with the prior art, this can reduce the probability of maintenance personnel being injured due to the accidental closing of the foot pedal 11.

[0045] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
