Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of mine hydraulic support footboard, especially relates to a replaceable mine footboard. BACKGROUND

[0002] The hydraulic support footboard with the rear human passage can be lifted open when the jack is overhauled, but the footboard is still heavy in the manufacturing process although the thin steel plate is used, the footboard cannot rotate 90 degrees due to the design reason or other reasons when the jack is overhauled, and the footboard needs to be lifted open by force, the surface of the footboard lacks the antiskid design, and the metal footboard surface can be gradually rusted, and the service life of the footboard is reduced. SUMMARY

[0003] The utility model discloses a replaceable mine footboard.

[0004] To achieve the above-mentioned purpose, the utility model adopts the technical scheme that:

[0005] A replaceable mine footboard, including support frame and pedal, the support frame and pedal are connected through bolt, the support frame is welded by section steel, is equipped with hinged support on the support frame, the hinged support is connected with the hydraulic support of the footboard bottom through the connecting lug plate and the hinge shaft and rotates.

[0006] Further, the pedal is ABS resin with fire resistance and anti-static, the upper part of the pedal is provided with uniform conical convex points, and the height of the conical convex points increases along the length direction of the pedal.

[0007] Further, the support frame is rectangular or special-shaped, the hinged support is located on one side or both sides of the support frame, and a handle is further arranged on the support frame to facilitate lifting or dismounting the footboard.

[0008] Further, the shape of the pedal matches the support frame, and the pedal is integral or split, so that only the pedal of the easily-worn part needs to be replaced, thereby saving cost.

[0009] The utility model has the advantages that:

[0010] 1. The upper pedal is made of new ABS engineering plastic, which has impact resistance, heat resistance, low temperature resistance, chemical resistance and excellent electrical performance, and also has easy processing, stable product size, good surface gloss and other characteristics, and the weight of the pedal is lighter than that of general steel material, easy to operate, reduces the operation burden of workers, and is generally only half of the weight of the corresponding steel material pedal.

[0011] 2. Because the surface of the pedal is decorated with a conical pattern of raised dots, and the height of the dots varies at regular intervals along the length of the pedal, the pedal's grip is enhanced when a person walks on it.

[0012] 3. High-strength bolts are used to connect the upper pedal to the lower support frame. If either part is damaged in extreme circumstances, only the corresponding part needs to be replaced, without replacing the entire foot pedal. Attached Figure Description

[0017] Example 1

[0018] like Figures 1-2 As shown, a replaceable mining foot pedal includes a support frame 2 and a pedal 1, which are connected by bolts 3. The support frame is welded from structural steel and has a hinge support 4. The hinge support is rotatably connected to a hydraulic bracket at the bottom of the foot pedal via a connecting ear plate 5 and a hinge shaft. The pedal is made of fire-resistant and anti-static ABS resin, and has uniformly distributed conical protrusions on its upper part, with the height of the protrusions increasing sequentially along the length of the pedal. The support frame is rectangular, with the hinge support located on the left and right sides. The support frame also has handles 6 for easy opening or disassembly of the foot pedal. The shape of the pedal matches the support frame. The pedal can be integral or modular; the modular design allows for replacement of only the easily worn parts of the pedal, saving costs.

[0019] Example 2

[0020] like Figures 3-4The shown replaceable mine footboard comprises a support frame 1 and a footboard 2, the support frame and the footboard are connected by bolts, the support frame is welded by section steel, the support frame is provided with a hinge support 3, the hinge support is rotatably connected with the hydraulic support at the bottom of the footboard through a connecting lug plate 4 and a hinge shaft. The footboard is made of ABS resin with fire resistance and anti-static, the upper part of the footboard is provided with uniform conical convex points, the height of the conical convex points increases along the length direction of the footboard. The support frame is rectangular and the two side edges of the support frame extend forward, the hinge supports are located at the left and right rear sides of the support frame, the support frame is further provided with a handle, which facilitates the lifting or dismounting of the footboard. The shape of the footboard matches the support frame, the footboard is integral or split, the split design can replace only the easily-worn part of the footboard, thereby saving cost.

[0021] In specific use, after the footboard is installed, if damage occurs due to surface wear or support frame damage during long-term use, the damaged part can be replaced alone, when the jack is overhauled, the hinge shaft is only needed to be removed and the footboard is lifted to open, thereby facilitating use.
