[0016] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0017] In the relevant technology, vertical shaft sinking is an important part of mine development. As a supporting device, the stability, load-bearing capacity and construction efficiency of the derrick directly affect the safety and progress of the shaft sinking operation. The escalator of the traditional derrick mostly adopts an integral structure, which is inconvenient to transport and install.

[0018] This embodiment provides a modular derrick for vertical shaft sinking to solve the problem of inconvenient transportation and installation of the escalator of the traditional derrick.

[0019] See also Figure 1-Figure 3 In this embodiment, a modular derrick for vertical shaft drilling includes an escalator 20 arranged on a frame body 10, and the escalator 20 includes a side beam 21 and a cross beam 22. The cross beam 22 is penetrated through the side beam 21, and a threaded hole 221 is provided at the end of the cross beam 22. A side wall of the threaded hole 221 is provided with a slot 222, and a positioning plate 23 is clamped in the slot 222. The positioning plate 23 has a positioning groove 232 clamped with the side beam 21, and a locking column 24 is screwed into the threaded hole 221, and the locking column 24 is screwed with the positioning plate 23.

[0020] By adopting the technical solution of this embodiment, the cross beam 22 and the side beam 21 are connected and fixed by the positioning plate 23, so that the escalator 20 is easy to disassemble and assemble, and the convenience of transportation and installation of the escalator is improved.

[0021] In this embodiment, the escalator 20 is integrally fixedly installed on the frame 10. The escalator 20 provides a passage for people to go up and down the frame 10. The escalator 20 is modularly designed as a whole, which is convenient for disassembly and assembly, and can improve the convenience of transportation and installation of the escalator.

[0022] Specifically, the escalator 20 includes two parallel side beams 21 and a plurality of cross beams 22 disposed between the two side beams 21 . The side beams 21 are hollow structures and handrails are welded to the side beams 21 . A plurality of through holes are evenly arranged on the side beams 21 along the longitudinal direction of the side beams 21 , and the through holes are used to pass the cross beams 22 .

[0023] In addition, the cross beam 22 as a whole is arranged vertically with the side beam 21, threaded holes 221 are provided at the two ends of the cross beam 22, and the threaded holes 221 are arranged coaxially with the cross beam 22, a slot 222 is opened on the side wall of the threaded hole 221, and the slot 222 as a whole extends along the axial direction of the cross beam 22, and the slot 222 passes through the side wall of the cross beam 22, the slot 222 is constructed as a T-shape, and the slot 222 is symmetrically arranged at both ends of the cross beam 22.

[0024] In addition, the positioning plate 23 is constructed as a T-shape that is compatible with the slot 222. The positioning plate 23 is integrally clamped inside the slot 222, and the positioning plate 23 can move radially along the cross beam 22 to complete the movement of the positioning plate 23 in the slot 222. The positioning plate 23 includes a clamping plate 231 that extends radially out of the cross beam 22. A positioning groove 232 is provided on the clamping plate 231. The width of the positioning groove 232 is equal to the wall thickness of the side beam 21. The positioning groove 232 is used to clamp with the wall of the side beam 21 at the aforementioned through hole.

[0025] It should be noted that when the positioning plate 23 is installed in place inside the slot 222, the threads on the positioning plate 23 compensate for the missing threads in the slot 222, so that a complete thread is formed inside the threaded hole 221. After the locking column 24 is screwed into the threaded hole 221, the locking column 24 will form a threaded engagement with the positioning plate 23. At the same time, the slot 232 on the card plate 231 will be engaged with the wall of the side beam 21 at the through hole, thereby realizing the axial positioning of the cross beam 22 and connecting and fixing the cross beam 22 to the side beam 21.

[0026] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
