Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic supports, in particular to a hydraulic support base pedal flip support device. Background Art

[0002] Hydraulic support base footrests provide safe and comfortable pedestrian access for coal miners underground. One side of the footrest is typically hinged to the hydraulic support base. Miners need to remove or flip the footrest upright when inspecting and maintaining the hydraulic system or jacks on the hydraulic support base. However, disassembling and assembling the footrest is time-consuming and labor-intensive, making it extremely inconvenient. Furthermore, if the footrest is flipped upright, it lacks proper fixings and is unstable, potentially causing it to fall over, endangering the safety of underground equipment maintenance personnel.

[0003] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the Invention

[0004] The purpose of the present invention is to address the deficiencies of the existing technology and thus provide a hydraulic support base pedal flip support device. When flipping the pedal, the present invention can stably support the pedal through the support rod to prevent the pedal from tipping over, providing a safe activity space for coal miners and making it convenient for coal miners to inspect and maintain the hydraulic system or jack of the hydraulic support base.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a hydraulic support base pedal flip support device, including a foot pedal, the rear side of the foot pedal is hinged on the hydraulic support base, a hook assembly is provided at the bottom of the foot pedal, and a support frame assembly located below the foot pedal is hinged on the hydraulic support base, and the support frame assembly and the hook assembly correspond to each other up and down and are snap-fitted.

[0006] Based on the above, the hook assembly includes a support beam, which is welded to the bottom of the foot pedal along the front-to-back direction. The bottom of the support beam is integrally formed with a plurality of hooks arranged in a front-to-back interval and bent backward.

[0007] Based on the above, the support frame assembly includes a support rod, which is arranged below the foot pedal in the front-to-back direction. The rear end of the support rod is horizontally bent 90 degrees to form an integral hinge shaft. Left and right transparent pin sleeves are welded on the hydraulic support base at the position below the corresponding support beam. The hinge shaft is rotatably connected in the pin sleeve. A pin hole is radially opened at one end of the hinge shaft passing through the pin sleeve. An open pin is installed in the pin hole to prevent the hinge shaft from falling off the pin sleeve. An L-shaped clamping rod parallel to the support rod and bent forward is welded on one side of the front end of the support rod. The L-shaped clamping rod is engaged with the corresponding hook. The length of the support rod is greater than the vertical distance between the pin sleeve and the foot pedal when the foot pedal is horizontal and less than or equal to the distance between the pin sleeve and the lowest hook on the corresponding side when the foot pedal is upright.

[0008] Based on the above, there are two hook assemblies and two support frame assemblies arranged symmetrically on the left and right.

[0009] The present invention has substantial features and progress compared to the prior art. Specifically, when the foot pedal is flipped, the support rod can stably support the foot pedal to prevent it from tipping over, providing a safe activity space for coal miners and making it convenient for coal miners to inspect and maintain the hydraulic system or jack of the hydraulic support base. The overall structure is simple and easy to use.

[0010] Furthermore, the bottom of the support beam is integrally formed with a plurality of hooks arranged at intervals in front and back. When the L-shaped hook is inserted into the corresponding different hooks, the support rod can stably support the foot pedal at different angles to meet different work needs.

[0015] The technical solution of the present utility model is further described in detail below through specific implementation methods.

[0016] like Figure 1 、 Figure 2 and Figure 3 As shown, a hydraulic support base pedal flip support device includes a foot pedal 1, the rear side of the foot pedal 1 is hinged on the hydraulic support base 2, and hook assemblies are symmetrically arranged on the left and right sides of the bottom of the foot pedal 1. A support frame assembly located below the foot pedal 1 is hinged on the hydraulic support base 2, and there are two support frame assemblies symmetrically arranged on the left and right. The two support frame assemblies correspond to the two hook assemblies one by one up and down and are engaged with each other.

[0017] The hook assembly includes a support beam 3, which is welded to the bottom of the footrest 1 along the front-to-back direction. The bottom of the support beam 3 is integrally formed with a plurality of hooks 4 arranged in a front-to-back spacing and bent backward.

[0018] The support frame assembly includes a support rod 5, which is arranged below the foot pedal 1 in the front-to-back direction. The rear end of the support rod 5 is horizontally bent 90 degrees to form an integral hinge shaft 6. A left and right transparent pin sleeve 7 is welded on the hydraulic support base 2 at a position corresponding to the lower portion of the support beam 3. The hinge shaft 6 is rotatably connected to the pin sleeve 7. A pin hole is radially opened at one end of the hinge shaft 6 passing through the pin sleeve 7. An open pin 8 is installed in the pin hole to prevent the hinge shaft 6 from falling off the pin sleeve 7. An L-shaped clamping rod 9 is welded on one side of the front end of the support rod 5, which is parallel to the support rod 5 and bent forward. The L-shaped clamping rod 9 is engaged with the corresponding hook 4. The length of the support rod 5 is greater than the vertical distance between the pin sleeve 7 and the foot pedal 1 when the foot pedal 1 is horizontal and is less than or equal to the distance between the pin sleeve 7 and the lowest hook 4 on the corresponding side when the foot pedal 1 is upright.

[0019] The working principle of this embodiment is: lift the foot pedal 1 and flip it to a certain angle, and then respectively insert the L-shaped clamping rods 9 at the front ends of the two support rods 5 into the corresponding clamping hooks 4 on the left and right sides of the bottom of the foot pedal 1. Then, the two support rods 5 can stably support the foot pedal 1 and prevent the foot pedal 1 from tipping over, making it convenient for coal miners to inspect and maintain the hydraulic system or jack of the hydraulic support base 2, and will not affect the personal safety of coal miners when inspecting and maintaining the hydraulic system or jack of the hydraulic support base 2.

[0020] According to work needs, the L-shaped clamping rod 9 is clamped into the corresponding different clamping hooks 4, and the support rod 5 can stably support the footrest 1 at different angles.
