Description

Technical Field

[0001] This utility model relates to the field of power distribution equipment technology, specifically a mobile trolley power distribution panel. Background Technology

[0002] In many industrial production, construction, and temporary power supply scenarios, there is a need for flexible and convenient power distribution devices. Traditional switchboards are usually fixed in one location, making it difficult to meet the needs of frequent changes in power supply location. Existing mobile power distribution devices suffer from unreasonable structural design, inconvenient movement, poor protection performance, and susceptibility to damage to internal electrical components during movement. For example, in underground mining sites, due to the large mining area, fixed trolley switchboards are limited by cable length, affecting the normal power supply for trolley operations. Furthermore, long cable lengths are prone to damage and leakage, and can even lead to safety accidents when there is water on the ground. Therefore, developing a stable and easily movable mobile trolley switchboard is of significant practical importance. Utility Model Content

[0003] The purpose of this invention is to provide a mobile trolley power distribution panel to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a mobile trolley distribution panel, including a frame, a reinforcing rib fixedly connected to the inner side of the frame, a distribution panel base fixedly connected to the outer wall of the reinforcing rib, an axle fixedly connected to the top of the frame, a bearing fixedly connected to the outer wall of the axle, a cable reel fixedly connected to the outer wall of the bearing, two wheels provided at the bottom of the frame, and a cable reel fixing structure provided on the side of the cable reel.

[0005] Preferably, the cable reel is provided with a pin and a cable head fixing structure on its side for locking the cable after it has been unwound and retracted.

[0006] Preferably, the bottom of the frame is provided with two support feet, which are used to support the wheels off the ground to maintain the stability of the distribution panel when it is stationary.

[0007] Preferably, the pin is used to lock the rotation of the drum.

[0008] Preferably, the frame of the mobile trolley is made of steel pipe welded to form a cuboid frame structure, which not only ensures the strength of the frame, but also reduces the overall weight and facilitates movement.

[0009] Preferably, the cable head fixing structure is used to fix the cable end and prevent the cable from falling off the cable reel.

[0010] Compared with the prior art, this utility model provides a mobile trolley power distribution panel, which has the following advantages:

[0011] 1. This mobile trolley power distribution panel solves the problems of insufficient cable length during underground mining, which can easily lead to cable damage due to friction on the ground and contact with water, increasing safety hazards, equipment damage, and the risk of electric shock to personnel, thus reducing the possibility of production safety accidents.

[0012] 2. This mobile trolley distribution panel solves the problems of inconvenient movement and poor protection performance of existing distribution panels, and realizes the functions of convenient and flexible movement and stable and reliable operation. Attached Figure Description

[0017] This utility model provides the following technical solution:

[0018] Combination Figures 1 to 3 The vehicle includes a frame 1, a reinforcing rib 2 fixedly connected to the inner side of the frame 1, a distribution panel base 3 fixedly connected to the outer wall of the reinforcing rib 2, an axle 4 fixedly connected to the top of the frame 1, a bearing 5 fixedly connected to the outer wall of the axle 4, a cable reel 6 fixedly connected to the outer wall of the bearing 5, two wheels 7 at the bottom of the frame 1, and a cable reel fixing structure 9 on the side of the cable reel 6.

[0019] The cable reel 6 has a pin 10 and a cable head fixing structure 8 on its side, which are used to lock the cable after it has been reeled in and out.

[0020] The bottom of the frame 1 is equipped with two support feet, which are used to support the wheels 7 off the ground to maintain the stability of the distribution panel when it is stationary.

[0021] Pin 10 is used to lock the rotation of the drum.

[0022] The frame 1 of the mobile trolley is made of steel pipe welded to form a rectangular frame structure, which not only ensures the strength of the frame 1, but also reduces the overall weight and facilitates movement.

[0023] The cable head fixing structure 8 is used to fix the cable end and prevent the cable from falling off the cable reel 6.

[0024] In actual operation, when this device is used, according to the design of the mining stratification roadway, 20 steel bars with a diameter of 10mm and a diameter of 645mm and two angle irons with a length of 2 meters are processed into two circular discs with a diameter of 700mm on the ground surface in advance; then, 10 steel bars with a diameter of 10mm and a diameter of 500mm are used to weld the two disc pads to form a cable reel, and then a frame and a base for the distribution panel are welded together using one-inch steel pipes and angle irons. Finally, the two wheels and the frame are welded together to form a mobile trolley distribution panel.

[0025] Transport the processed mobile trolley switchboard to the work site and install the cable and switchboard on the trolley. When the trolley is working in the longwall face, the switchboard can be placed at a suitable position with the required cable length. After the trolley finishes its work, retrieve the cable and place the mobile trolley switchboard in a suitable position for use in the next operation.
