[0028] 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.

[0029] In related technologies, hydraulic supports are coal mining face support equipment that uses high-pressure hydraulic power and is composed of hydraulic cylinders, valves, and some metal structural components. They are used to support the roof of underground coal mine working faces and protect the safety of equipment and personnel. Hydraulic supports mainly consist of hydraulic cylinders (columns, jacks), load-bearing structural components (top beams, shield beams, and bases, etc.), pushing devices, control systems, and other auxiliary devices. The lug plate of the top beam column is a key component for fixing the column head; existing top beam column lug plates are difficult to repair underground by welding after damage.

[0030] In view of this, the purpose of this embodiment is to provide a top beam column pressure plate mechanism to improve the convenience of maintenance of the top beam column ear plate.

[0031] Please see Figures 1-4 In this embodiment, a top beam column pressure plate mechanism includes an upper fixing component 10, a lower fixing component 20, and a pressure plate 30. The upper fixing component 10 and the lower fixing component 20 are hinged and wrapped around the outside of the top beam 50. Bolts 40 with inner ends abutting against the top beam 50 are screwed onto the upper fixing component 10 and the lower fixing component 20. The lower fixing component 20 is provided with a pressure plate 30. The pressure plate 30 is engaged with the column socket reinforcement plate of the top beam 50 and presses the column head pin of the column 60.

[0032] By adopting the technical solution of this embodiment, the gap between the lower fixing component 20 and the top beam 50 can be adjusted by rotating the bolt 40, which can provide suitable space for the maintenance of the top beam column ear plate and improve the convenience of maintenance.

[0033] In this embodiment, the upper fixing component 10 includes a top plate 11 and two upper side plates 12. The two upper side plates 12 form a U-shaped structure with the top plate 11. The two upper side plates 12 are symmetrically arranged on both sides of the top plate 11. Both upper side plates 12 are arranged perpendicular to the top plate 11. Bolts 40 are screwed onto the two upper side plates 12, and the bolts 40 are arranged perpendicular to the upper side plates 12.

[0034] In addition, the lower fixing assembly 20 includes a base plate 21 and two lower side plates 22. The two lower side plates 22 form a U-shaped structure with the base plate 21. The two lower side plates 22 are arranged perpendicularly to the base plate 21 and are symmetrically arranged on both sides of the base plate 21. The lower side plates 22 are hinged to the upper side plates 21 and are arranged parallel to the upper side plates 21. Bolts 40 are also screwed onto the base plate 21 and are arranged perpendicularly to the base plate 21. A pressure plate 30 is connected to the base plate 21 and is arranged parallel to the lower side plates 22.

[0035] It should be noted that the upper side plate 11 of the upper fixing component 10 and the lower side plate 21 of the lower fixing component 20 are connected by a pin, so that the upper fixing component 10 and the lower fixing component 20 form a rectangular frame and wrap around the outside of the top beam 50. The gap between the upper fixing component 10 and the lower fixing component 20 and the top beam 50 can be adjusted by four bolts 40, and the upper fixing component 10 and the lower fixing component 20 can be pre-tightened. The pressure plate 30 is engaged with the column socket reinforcement plate of the top beam 50 to prevent the pressure plate 30 from moving back and forth. At the same time, the pressure plate 30 presses the column head pin of the column 60, so that the column and the column socket of the top beam can be fixed in the corresponding position.

[0036] It should be understood that the top beam column pressure plate mechanism can solve the problem of not being able to fix the column head after the top beam column ear plate is damaged, and can be quickly repaired downhole, solving the problem of time-consuming and labor-intensive maintenance of hydraulic supports when they are brought to the surface.

[0037] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
