[0003] Since the traditional explosion-proof substation is only carried by tires when moving, the bumping caused by uneven road surface is easy to cause damage to the internal structure of the explosion-proof substation, thereby reducing the service life and carrying effect of the overall explosion-proof substation. UTILITY MODEL CONTENTS

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0006] A multi-voltage mine explosion-proof substation, comprising an explosion-proof substation body, a mobile seat is fixedly installed at the bottom end of the explosion-proof substation body, an auxiliary box is slidably connected to the inner walls of the two ends of the mobile seat, a driving rod and two driven rods are rotatably connected to the inner side walls of the mobile seat, three mobile wheels are fixedly installed on the outer sides of the two driven rods, a driven wheel is rotatably connected to the inner side walls of the two ends of the auxiliary box, the inner walls of the auxiliary box are rotatably connected with three linkage rods, an auxiliary wheel is rotatably connected to the bottom end of the three linkage rods, and a track is sleeved on the outer sides of the driven wheel and the auxiliary wheel.

[0007] As a preferred embodiment of the utility model, the inner side walls of the auxiliary box are rotatably connected with three jacks, a bottom rod is slidably connected to the bottom end of the three jacks, and one end of the auxiliary wheel is rotatably connected with the bottom end of the bottom rod.

[0008] As a preferred embodiment of the utility model, springs are sleeved on the outer sides of the jacks and the bottom rod, and the two ends of the springs are fixedly connected with the top end of the jack and the top end of the bottom rod, respectively.

[0009] In a preferred embodiment of this utility model, two electro-hydraulic rods are rotatably connected to the inner walls of both ends of the movable seat, and the telescopic ends of the two electro-hydraulic rods are fixedly connected to the top of the auxiliary box.

[0010] In a preferred embodiment of this utility model, pulleys are fixedly mounted on the outer sides of both the driven rod and the driving rod, and a transmission belt is sleeved on the outer side of the pulleys.

[0011] In a preferred embodiment of this invention, a drive motor is fixedly installed on the inner side wall of the movable seat, and the output end of the drive motor is fixedly connected to one end of the drive rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] Please refer to Figures 1-5 The present application provides the following technical solutions: a multi-voltage mine explosion-proof substation, comprising an explosion-proof substation body 1, a mobile seat 2 fixedly installed at the bottom end of the explosion-proof substation body 1, an auxiliary box 3 slidably connected to the inner walls of both ends of the mobile seat 2, a driving rod 21 and two driven rods 22 rotatably connected to the inner side walls of the mobile seat 2, three mobile wheels 23 fixedly installed on the outer sides of the two driven rods 22, a driven wheel 31 rotatably connected to the inner side walls of both ends of the auxiliary box 3, the inner walls of both ends of the driven rod 22 slidably connected to the auxiliary box 3 and the driven wheel 31, three linkage rods 4 rotatably connected to the inner side walls of the auxiliary box 3, an auxiliary wheel 41 rotatably connected to the bottom end of the three linkage rods 4, and a track 5 sleeved on the outer sides of the driven wheel 31 and the auxiliary wheel 41.

[0024] In specific use, when the explosion-proof substation needs to be moved, the driving rod 21 can directly drive the driven rod 22, so that the driven rod 22 can drive the mobile wheels 23 to rotate inside the mobile seat 2, thereby directly driving the explosion-proof substation to move quickly when the ground is flat. At this time, the auxiliary box 3 drives the track 5 to be inside the mobile seat 2 and not to contact the ground. When the ground is relatively uneven, the auxiliary box 3 can slide downward inside the mobile seat 2, so that the track 5 contacts the ground at this time. At this time, the two ends of the driven rod 22 and the center of the driven wheel 31 are mutually engaged. Then, the driven rod 22 can drive the driven wheel 31 to rotate inside the auxiliary box 3, while the auxiliary wheel 41 inside the track 5 remains engaged with the inside of the track 5, which can assist the transmission of the track 5 when the track 5 is driven by the driven wheel 31. This can more efficiently adapt to different grounds for movement, thereby improving the movement effect of the track 5 driving the explosion-proof substation and improving the stability of the explosion-proof substation moving.

[0025] Preferably, the inner side wall of the auxiliary box 3 is rotationally connected with three top rods 42, the bottom end of the three top rods 42 is slidingly connected with a bottom rod 43, and the bottom end of the bottom rod 43 is rotationally connected with one end of the auxiliary wheel 41.

[0026] In specific use, when the auxiliary box 3 drives the track 5 to slide downward and contact the ground, the auxiliary wheel 41 can be more efficiently applied to move the track 5 in different ground environments through the sliding between the top rod 42 and the bottom rod 43, the connection between the bottom rod 43 and the auxiliary wheel 41, and the rotation between the linkage rod 4 and the auxiliary wheel 41.

[0027] Preferably, the outer side of the top rod 42 and the bottom rod 43 is sleeved with a spring 44, and the two ends of the spring 44 are fixedly connected with the top end of the top rod 42 and the top end of the bottom rod 43, respectively.

[0028] In specific use, when the auxiliary box 3 is collected into the inside of the moving seat 2, the spring 44 is in a relaxed state, and the track 5 can maintain a certain distance from the ground. When the auxiliary box 3 moves downward, the track 5 contacts the ground, and at this time, the sliding between the top rod 42 and the bottom rod 43 and the force between the spring 44 and the top rod 42 and the bottom rod 43 can improve the movement of the auxiliary wheel 41 and the track 5 in different ground conditions.

[0029] Preferably, the inner side wall of the moving seat 2 is rotationally connected with two electric hydraulic rods 6, and the telescopic ends of the two electric hydraulic rods 6 are fixedly connected with the top end of the auxiliary box 3.

[0030] In specific use, the auxiliary box 3 can be driven to slide in the inside of the moving seat 2 by the electric hydraulic rod 6, so that the explosion-proof substation can be directly driven by the moving wheel 23 or assisted to move by the track 5 in the inside of the auxiliary box 3 when moving, which is more convenient for adjustment according to different ground conditions.

[0031] Preferably, the outer side of one of the driven rod 22 and the driving rod 21 is fixedly installed with a belt wheel 24, and the outer side of the belt wheel 24 is sleeved with a transmission belt 25.

[0032] In specific use, when the driven rod 22 needs to be rotated to drive the explosion-proof substation to move, the driving rod 21 can be driven in the inside of the moving seat 2, so that the driven rod 22 can be rotated through the linkage action of the belt wheel 24 and the transmission belt 25, and then the explosion-proof substation can be moved by the moving wheel 23 or the track 5.

[0033] Preferably, the inner side wall of the moving seat 2 is fixedly installed with a driving motor 26, and the output end of the driving motor 26 is fixedly connected with one end of the driving rod 21.

[0034] In specific use, when the explosion-proof transformer substation needs to be moved, the driving of the driving motor 26 drives the driving of the main rod 21, so that the main rod 21 can rotate in the inside of the moving seat 2, and then the moving wheel 23 and the track 5 can be driven.

[0035] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included within the scope of the present application.
