Description

Technical Field

[0001] This utility model relates to the field of substation technology, specifically to a fixed structure for the body of a mine explosion-proof mobile substation used for vertical hoisting. Background Technology

[0002] Previously, the fixation between the mobile substation casing and the transformer body was insufficient for vertical hoisting into the shaft. The previous method involved simply positioning the casing and transformer body using locating holes in the lower clamp and locating pins on the bottom of the enclosure, then fixing it to the enclosure with a fixing plate through holes in the upper clamp. This only ensured that the transformer body wouldn't move along the Z-axis within the casing. During vertical hoisting, the lack of a reliable connection along the X-axis allowed for displacement of the transformer body, potentially even leading to tipping and damage. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a fixed structure for the body of a mine explosion-proof mobile substation used for vertical hoisting. By improving the fixed structure, the requirements for vertical hoisting down into the mine can be met.

[0004] This utility model is achieved through the following technical solution: a fixed structure for the body of a mine explosion-proof mobile substation for vertical hoisting is provided, including a shell that encloses the substation body, at least two lower clamping holes are opened on the lower clamping member of the substation body, a positioning pin is fixedly connected to the bottom surface of the shell and inserted into the lower clamping member positioning hole, a connecting beam is fixedly connected between the inner walls of the two long sides of the shell, the connecting beam is fixedly connected to one end of the upper clamping member of the substation body by bolts, and an end connecting plate is fixedly connected to the inner wall of the short side of the shell, the end connecting plate is fixedly connected to the other end of the upper clamping member of the substation body by bolts.

[0005] In this design, the substation body is placed inside the housing and supported on the bottom surface of the housing. Positioning pins are inserted into the positioning holes of the lower clamping member of the substation body to position the lower end of the substation body. The upper end of the substation body is positioned in the Y-axis direction via a connecting beam, and in the X-axis direction via an end connecting plate. This achieves the fixation of the substation body.

[0006] As an optimization, a fixing angle steel is fixedly connected to the inner wall of the short side of the shell, and the end connecting plate is fixedly connected to the fixing angle steel by bolts. In this solution, the fixing angle steel is welded to the inner wall of the short side, which facilitates the fixed connection between the end connecting plate and the short side of the shell and makes installation easier.

[0007] As an optimization, two end connecting plates are provided and fixed side-by-side to the inner wall of the same short side of the housing. This effectively fixes the clamping part on the end piece in the X-axis direction.

[0008] As an optimization, the end connecting plate is vertically positioned and fixed to the side of the clamping component on the device body, while the connecting beam is fixed to the top surface of the clamping component on the device body. In this design, the vertical positioning of the end connecting plate improves the support strength in the X-axis direction, and the connection beam fixed to the top surface of the clamping component on the device body facilitates installation and connection from the top surface.

[0009] As an optimization, at least two side connecting plates are fixedly connected to the inner wall of the long side of the shell, and the side connecting plates are fixedly connected to the clamping parts on the vessel body by bolts. In this solution, the fixing strength of the clamping parts on the vessel body is further improved by the side connecting plates.

[0010] As an optimization, a fixing plate is attached and fixed to the inner wall of the long side of the housing, and the side connecting plate is fixed to the fixing plate by bolts. The fixing plate provided in this solution facilitates the connection and installation of the side connecting plate.

[0011] The beneficial effects of this utility model are as follows:

[0012] This utility model features a highly versatile fixed structure that can meet the needs of different types of mobile substations. The structure is robust and easy to disassemble. All parts are connected by bolts, resulting in a simple structure. Furthermore, all connectors can be opened from the casing, facilitating disassembly, simplifying manufacturing, and reducing costs.

[0016] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0017] like Figure 1 As shown, the present invention provides a fixed structure for a mine explosion-proof mobile substation body for vertical hoisting, including a housing 1 that encloses the substation body. The housing 1 is a rectangular housing with an opening at the top, and an end cap is detachably connected to the upper end, which is not shown in the figure.

[0018] Since the upper part of the substation body is the upper clamp 7 and the lower part is the lower clamp, the upper clamp 7 and the lower clamp are usually fixed when fixing the substation body.

[0019] The substation body has at least two lower clamping holes 6 on its lower clamping member. In this embodiment, four lower clamping holes 6 are provided and located at the four corners of the lower clamping member. Positioning pins inserted into the lower clamping holes 6 are fixed to the bottom surface of the housing 1. Since the substation body is placed on the bottom surface of the housing 1, the substation body is fixed in the Z-axis direction, meaning it cannot move up or down relative to the housing 1. In this application, the Z-axis direction refers to the vertical direction in real space. Figure 1 The middle view is a top view. Figure 1 The left and right directions are the X-axis directions. Figure 1 The vertical direction is the Y-axis direction.

[0020] Since shell 1 is a rectangular shell with an opening at the top, such as Figure 1 As shown in the top view, the long sides on the top and bottom are the long inner walls of the shell 1, and the left and right sides are the short inner walls of the shell 1.

[0021] A connecting beam 8 is fixedly connected between the two long inner walls of the shell 1. Both ends of the connecting beam 8 are fixed to the long inner walls of the shell 1 by bolts. In this embodiment, a fixing plate 5 is welded to the long inner wall of the shell 1, and the fixing plate 5 has threaded holes. Both ends of the connecting beam 8 are connected to the fixing plate 5 by bolts. The connecting beam 8 is fixedly connected to one end of a clamping member 7 on the device body by bolts. In this embodiment, the connecting beam 8 is fixed to the top surface of the clamping member 7 on the device body.

[0022] An end connecting plate 3 is fixedly connected to the inner wall of the short side of the housing 1. The end connecting plate 3 is fixedly connected to the other end of the clamping member 7 on the device body by bolts. Two end connecting plates 3 are provided and fixedly connected side by side to the inner wall of the short side of the housing 1. In this embodiment, the end connecting plate 3 is vertically arranged and fixed to the side of the clamping member 7 on the device body. A fixing angle steel 2 is welded to the inner wall of the short side of the housing 1, and the end connecting plate 3 is fixedly connected to the fixing angle steel 2 by bolts.

[0023] At least two side connecting plates 4 are fixedly connected to the long inner wall of the housing 1. In this embodiment, two side connecting plates 4 are connected to the long inner wall of each housing 1. The side connecting plates 4 are fixedly connected to the clamping member 7 on the body by bolts. A fixing plate 5 is attached and fixedly connected to the long inner wall of the housing 1. The side connecting plates 4 are fixedly connected to the fixing plate 5 by bolts.

[0024] The installation method of this utility model:

[0025] Weld fixed angle steel 2 and fixed plate 5 to the inner wall of the shell, weld positioning nails to the bottom surface of the shell, and open positioning holes 6 for the lower clamp on the body. When the substation body is lowered into the shell 1, use the side connecting plate 4 to fasten the substation body to the fixed plate 5 on the shell with bolts, use the end connecting plate 3 to fix the substation body to the fixed angle steel 2 on the shell with bolts, and use the connecting beam 8 to fix the substation body to the fixed plate 5 on the shell with bolts 9. At this time, the substation body and the shell are firmly connected in all directions, which can meet the needs of vertical hoisting.
