Description

Technical Field

[0001] This utility model relates to the field of trackless vehicles for non-coal mines, specifically to an auxiliary power supply device for trackless vehicles for non-coal mines. Background Technology

[0002] Trackless vehicles in non-coal mines are self-propelled tire vehicles specifically designed for use in inclined ramps and / or tunnels of underground metal and non-metal mines. These vehicles are primarily used for transporting personnel, materials, or performing other mining operations. They are typically equipped with advanced braking systems to ensure safety and reliability in complex underground environments. In addition, trackless vehicles must meet specific safety technical requirements, including but not limited to vehicle lighting, signaling devices, maximum speed, regular maintenance and inspection, and driver qualification requirements. These vehicle design and usage rules are designed to improve the safety and production efficiency of mining operations. When the main power supply and auxiliary power supply device are electrically connected via plugs and sockets, the complex and harsh environment of non-coal mines can cause the plugs and sockets to loosen or fall off due to the bumps generated during the operation of the trackless vehicle. Although the trackless vehicle can provide some anti-loosening capability between the plugs and sockets of the main power supply and auxiliary power supply device through spring washers or anti-loosening nuts, the anti-loosening effect is not ideal. During the operation of the trackless vehicle, the spring washers or anti-loosening nuts will inevitably age or wear due to the bumps on the road surface, which will cause the plugs and sockets of the main power supply and auxiliary power supply device to loosen or fall off, thereby reducing the reliability and safety of the trackless vehicle operation. Therefore, an auxiliary power supply device for trackless vehicles in non-coal mines is proposed to address the above problems. Utility Model Content

[0003] The purpose of this utility model is to provide an auxiliary power supply device for trackless vehicles in non-coal mines, which has a dual anti-disconnection capability. The dual anti-disconnection structure improves the connection stability between the connector plug and the connector slot. Therefore, when the trackless vehicle is running, the connector plug and connector slot on the main power supply and auxiliary power supply will not become loose or fall off due to road bumps, thereby improving the reliability and safety of the trackless vehicle and solving the problems mentioned in the background art.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] Please see Figure 1-6 This utility model provides a technical solution: An auxiliary power supply device for a trackless vehicle in a non-coal mine includes a main power supply 1 and an auxiliary power supply 2. A connecting wire 3 is electrically connected to one side of the main power supply 1, and a connecting plug 4 is electrically connected to the end of the connecting wire 3 away from the main power supply 1. A connecting support plate 5 is fixedly connected to the outside of the connecting plug 4. A connecting slot 6 is provided on one side of the auxiliary power supply 2. A first anti-detachment component 7 is provided on the outside of the connecting support plate 5, and a second anti-detachment component 8 is provided on the outside of the connecting slot 6. The first anti-detachment component 7 includes a first anti-detachment disc 701, which is disposed on the outside of the connecting support plate 5, and its inner side is rotatably connected to the outside of the connecting support plate 5. The anti-detachment disc 701 has several first mounting slots 702 arranged in a ring array on one side wall near the auxiliary power supply 2. A first magnetic block 703 is fixedly connected in the first mounting slot 702. The second anti-detachment component 8 includes a second anti-detachment disc 801, which is fixedly connected to one side of the auxiliary power supply 2 and corresponds to the position of the connection slot 6. A connection through slot 802 matching the specifications of the connection slot 6 is opened at the center of the second anti-detachment disc 801. The second anti-detachment disc 801 has several second mounting slots 803 arranged in a ring array on one side wall near the main power supply 1. A second magnetic block 804 is fixedly connected in the second mounting slot 803.

[0017] As a further implementation of this solution, a plurality of anti-detachment blocks 704 arranged in a ring array are fixedly connected to the side wall of the first anti-detachment disc 701 near the first magnetic block 703. One end of the anti-detachment block 704 is provided with a limiting slot 705. A plurality of anti-detachment slots 805 arranged in a ring array are provided on the side wall of the second anti-detachment disc 801 near the second magnetic block 804. One end of the inner cavity of the anti-detachment slot 805 is fixedly connected with a rubber block 806. Through the cooperative use of the anti-detachment blocks 704, the limiting slots 705, the anti-detachment slots 805 and the rubber block 806, the connection stability between the first anti-detachment disc 701 and the second anti-detachment disc 801 can be enhanced. Therefore, when the trackless vehicle is running, the first anti-detachment disc 701 and the second anti-detachment disc 801 will not become loose or fall off due to road bumps.

[0018] As a further implementation of this solution, the anti-detachment block 704 is disposed between adjacent first mounting slots 702, and the anti-detachment slot 805 is disposed between adjacent second mounting slots 803. The number of anti-detachment blocks 704 and anti-detachment slots 805 are equal and their positions correspond. The length of the anti-detachment block 704 is less than the length of the anti-detachment slot 805. The anti-detachment blocks 704 and anti-detachment slots 805 are of the same specification. The staggered arrangement of the anti-detachment blocks 704 and the first mounting slots 702 and the staggered arrangement of the anti-detachment slots 805 and the second mounting slots 803 can simultaneously make the positions of the first magnetic block 703 and the second magnetic block 804 correspond after the anti-detachment blocks 704 and the anti-detachment slots 805 are engaged. After the anti-detachment blocks 704 and the anti-detachment slots 805 are engaged, the first magnetic block 703 and the second magnetic block 804 are magnetically attracted simultaneously to achieve the purpose of double anti-detachment.

[0019] As a further implementation of this solution, the limiting slot 705 and the rubber block 806 are positioned correspondingly and matched in specifications. The cooperation between the limiting slot 705 and the rubber block 806 can provide a locking capability between the anti-detachment block 704 and the anti-detachment slot 805.

[0020] Workflow: When the main power supply 1 and auxiliary power supply 2 are electrically connected, firstly, bring the connecting support plate 5 close to the second anti-detachment plate 801 in the second anti-detachment assembly 8, rotate the first anti-detachment plate 701 in the first anti-detachment assembly 7 outside the connecting support plate 5, so that the positions of the first magnetic block 703 in the first mounting groove 702 on the first anti-detachment plate 701 and the second magnetic block 804 in the second mounting groove 803 on the second anti-detachment plate 801 are staggered, and the anti-detachment locking block 704 is still within the range of the anti-detachment locking groove 805, and then... When the first anti-detachment disc 701 is attached to the second anti-detachment disc 801, the connector 4 at one end of the connecting wire 3 on the main power supply 1 will be inserted into the connecting slot 6 through the connecting groove 802 on the second anti-detachment disc 801, thus electrically connecting the main power supply 1 and the auxiliary power supply 2. The main power supply 1 is the main power supply, and the auxiliary power supply 2 is the backup power supply. At the same time as the first anti-detachment disc 701 is attached to the second anti-detachment disc 801, the anti-detachment locking block 704 will be inserted into the anti-detachment locking slot 805. Then, the first anti-detachment disc 701 will be rotated. This causes the anti-detachment block 704 to rotate towards the rubber block 806 until the rubber block 806 inserts into the limiting slot 705 at the end of the anti-detachment block 704, thus engaging the anti-detachment block 704 and the anti-detachment slot 805. As the first anti-detachment disc 701 rotates, the first magnetic blocks 703, positioned alternately, overlap and contact the second magnetic blocks 804, magnetically attracting them. This completes the engagement between the anti-detachment block 704 and the anti-detachment slot 805. The magnetic attraction of the first magnetic block 703 and the second magnetic block 804 is synchronized, ultimately achieving a dual anti-detachment purpose through the double structure of snap-fit ​​and magnetic attraction between the first anti-detachment disc 701 and the second anti-detachment disc 801. This improves the connection stability between the connector plug 4 and the connector slot 6, so that the connector plug 4 and the connector slot 6 on the main power supply 1 and the auxiliary power supply 2 will not become loose or fall off due to road bumps when the trackless vehicle is running, thereby improving the reliability and safety of the trackless vehicle operation.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
