[0002] In coal mining operations, electric locomotives are important means of transportation, and the charging status and efficiency of their power boxes are crucial to the normal operation of the entire mine. During the charging process of the electric locomotive power box, it is also necessary to use it in conjunction with a charging monitor, which can monitor the charging status of the power box in real time and automatically adjust the charging current and voltage as needed to ensure the safety and efficiency of the power box during the charging process.

[0003] At present, when the existing power box and the charging monitor are used together, bolts are generally used to directly install the charging monitor on the power box for connection. Although this method can provide strong connection stability, when the charging monitor fails and needs to be disassembled for maintenance, the bolts need to be removed one by one first, and then installed one by one after the maintenance is completed. The disassembly and assembly process is time-consuming and laborious, and it is impossible to quickly disassemble and replace in an emergency. In addition, when the bolts are rusted, the disassembly difficulty is further increased;

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a coal mine electric locomotive power box charging monitor with an automatic clamping structure to solve the above-mentioned technical defects. The utility model realizes a quick anti-detachment connection between the charging monitor body and the power box body through the snap connection of the mounting seat and the mounting plate, and the cooperation of the fixing components, which greatly improves the disassembly and assembly efficiency between the two, and the position of the L-shaped plate on the mounting plate is adjustable, which can further improve the adaptability of the clamping mechanism to different power box bodies.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Embodiment 1: In view of the problem that the charging monitor is generally installed on the power box directly by bolts in the prior art, the disassembly and assembly process is time-consuming and labor-intensive, and it cannot be quickly disassembled and replaced in an emergency, the following solution can be used to solve the problem;

[0029] See also Figure 1 - Figure 4 As shown, in this embodiment, the coal mine electric locomotive power box charging monitor with an automatic clamping structure includes a charging monitor body 1, a power box body 2 located on one side of the charging monitor body 1, and a clamping mechanism 3 is installed between the charging monitor body 1 and the power box body 2, which is used for rapid disassembly and assembly between the charging monitor body 1 and the power box body 2. The clamping mechanism 3 includes a mounting seat 31 fixedly connected to one side of the charging monitor body 1, and a mounting groove 32 running through the bottom of the mounting seat 31 is provided on one side of the mounting seat 31, and a mounting plate 33 is clamped in the mounting groove 32. The connection between the charging monitor body 1 and the power box body 2 can be quickly completed by engaging the mounting groove 32 on the mounting seat 31 with the mounting plate 33;

[0030] The cross-section of the mounting groove 32 is a T-shaped structure, and the mounting groove 32 does not pass through the top of the mounting seat 31, thereby limiting the separation between the mounting seat 31 and the mounting plate 33. The mounting seat 31 can only be moved upward for disassembly, thereby increasing the connection stability between the charging monitor body 1 and the power box body 2. Four groups of L-shaped plates 34 are installed on the side of the mounting plate 33 close to the power box body 2, and the L-shaped plates 34 are fixedly connected to the power box body 2 by bolts. A fixing component 4 is arranged in the mounting plate 33 for anti-detachment connection between the mounting seat 31 and the mounting plate 33, thereby improving the anti-separation effect of the charging monitor body 1 and the power box body 2 during use.

[0031] The fixing component 4 includes a slide plate 41, a clamping rod 42 and a spring 43. A slide groove 35 is provided on the side of the mounting plate 33 away from the charging monitor body 1 for installing the fixing component 4. The slide plate 41 is symmetrically slidably connected in the slide groove 35. The opposite side of the slide plate 41 is fixedly connected with a clamping rod 42 slidably connected to the mounting plate 33. A clamping hole 36 is provided on the inner side wall of the mounting groove 32 to engage with the corresponding end of the clamping rod 42. The end of the clamping rod 42 is engaged with the corresponding clamping hole 36 to avoid separation of the mounting seat 31 and the mounting plate 33 in the vertical direction. A spring 43 is fixedly connected between the slide plates 41 to ensure that the end of the clamping rod 42 extends out of the mounting plate 33 at all times, so that when the mounting plate 33 is engaged with the mounting seat 31, the anti-detachment connection between the two is further guaranteed.

[0032] The bottom of the slide groove 35 is rotatably connected to a rotating rod 44, and a pull rope 45 is fixedly connected between the outer wall of the rotating rod 44 and the corresponding slide plate 41. The bottom end of the rotating rod 44 passes through the outer side of the mounting plate 33 and is fixedly connected to a twist wheel 46. The rotating rod 44 is driven to rotate by rotating the twist wheel 46. The rotating rod 44 reels the pull rope 45. The reeled pull rope 45 drives the slide plates 41 on both sides to move relative to each other, forcing the end of the clamping rod 42 to move into the mounting plate 33, completing the separation of the clamping rod 42 and the corresponding clamping hole 36, and can quickly complete the separation of the mounting plate 33 and the mounting seat 31, thereby improving the convenience of disassembly and assembly of the charging monitor body 1 and the power box body 2.

[0033] A guiding slope 1 is provided at the top of the free end of the clamping rod 42. During the installation of the mounting seat 31 and the mounting plate 33, the guiding slope 1 at the end of the clamping rod 42 cooperates with the inner wall of the mounting groove 32 to automatically push the clamping rod 42 into the mounting plate 33, so that the mounting seat 31 and the mounting plate 33 are smoothly and quickly engaged. A guiding slope 2 is provided at the top edge of the mounting plate 33 to increase the convenience of engagement between the mounting seat 31 and the mounting plate 33.

[0034] Embodiment 2: The problem that the installation plate is inconvenient to install or the heat dissipation holes are easily blocked due to the presence of heat dissipation holes or other obstacles on different power boxes, thereby reducing the heat dissipation effect of the power box during charging, can be solved by the following solution;

[0035] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the coal mine electric locomotive power box charging monitor with an automatic clamping structure in this embodiment includes a charging monitor body 1, a power box body 2 located on one side of the charging monitor body 1, and a clamping mechanism 3 is installed between the charging monitor body 1 and the power box body 2. The clamping mechanism 3 includes a mounting seat 31 fixedly connected to one side of the charging monitor body 1, and one side of the mounting seat 31 is provided with a mounting groove 32 running through the bottom thereof, and a mounting plate 33 is clamped in the mounting groove 32. Four groups of L-shaped plates 34 are installed on the side of the mounting plate 33 close to the power box body 2, and the L-shaped plates 34 are fixedly connected to the power box body 2 by bolts. The mounting plate 33 is connected to the power box body 2 by the L-shaped plates 34, which can avoid the mounting plate 33 being directly installed on the outside of the power box body 2, thereby effectively avoiding the heat dissipation effect of the power box body 2 during charging when it is installed near the heat dissipation hole of the power box body 2. A fixing component 4 is arranged in the mounting plate 33.

[0036] A trapezoidal groove 37 is provided on one side of the mounting plate 33 at a position corresponding to each L-shaped plate 34. A trapezoidal block 38 is fixedly connected to the L-shaped plate 34 and is slidably connected to the corresponding trapezoidal groove 37. The trapezoidal groove 37 cooperates with the trapezoidal block 38 to achieve adjustable position of the L-shaped plate 34 on the mounting plate 33, thereby avoiding the problem that the L-shaped plate 34 cannot be installed due to the presence of heat dissipation holes in the mounting area of ​​the power box body 2, and further improving the installation adaptability of the clamping mechanism 3 to different power box bodies 2. Each trapezoidal groove 37 is provided with a plurality of adjustment holes 39 equidistantly along its length direction. An adjustment rod 310 compatible with the adjustment hole 39 is slidably installed on the L-shaped plate 34. The adjustment rod 310 is plugged in with the adjustment holes 39 at different positions to achieve fixed position of the L-shaped plate 34 on the mounting plate 33, thereby improving the installation stability when the mounting plate 33 is connected to the power box body 2.

[0037] The L-shaped plate 34 is provided with an active cavity that runs through the side close to the power box body 2, and a movable abutting rod 311 fixedly connected to the adjusting rod 310 is slidably connected in the active cavity. When the L-shaped plate 34 is connected to the power box body 2, one end of the movable abutting rod 311 is abutted by the power box body 2, pushing the free end of the adjusting rod 310 to extend out of the trapezoidal block 38, and then plugging into the adjusting hole 39 at the corresponding position, so that the L-shaped plate 34 is connected to the power box body 2 while completing its position fixation on the mounting plate 33. A spring 2 312 is fixedly connected between the movable abutting rod 311 and the active cavity and located on the outside of the adjusting rod 310. When the L-shaped plate 34 is separated from the power box body 2, one end of the movable abutting rod 311 is extended to the outside of the L-shaped plate 34 under the action of the compression elastic force of the spring 2 312, driving the free end of the adjusting rod 310 to move to the inside of the trapezoidal block 38, completing the separation of the adjusting rod 310 and the adjusting hole 39, so as to facilitate the position adjustment of the L-shaped plate 34.

[0038] The working process and principle of the utility model are as follows:

[0039] During use, the utility model adjusts the position of the trapezoidal block 38 in the trapezoidal groove 37 according to the installation position of the L-shaped plate 34 on the power box body 2, and then connects the L-shaped plate 34 to the power box body 2 by bolts, and in the process of connection, abuts one end of the movable abutment rod 311 through the outer wall of the power box body 2, pushes the free end of the adjustment rod 310 to extend out of the trapezoidal block 38, and then plugs into the adjustment hole 39 at the corresponding position, and completes the connection of the L-shaped plate 34 to the power box body 2 while simultaneously completing the fixation of its position on the mounting plate 33;

[0040] The bottom of the mounting groove 32 on the mounting seat 31 is aligned with the top of the mounting plate 33, and the mounting seat 31 is moved downward to complete the connection between the mounting seat 31 and the mounting plate 33. During the connection process, the inner wall of the mounting groove 32 is used to squeeze the guiding inclined surface 1 at the end of the clamping rod 42, forcing the clamping rod 42 to be pushed into the mounting plate 33, and the spring 1 43 is further compressed. After the mounting seat 31 and the mounting plate 33 are fully connected, the clamping rod 42 is pushed back to its original position under the action of the compression elastic force of the spring 1 43, and the end of the clamping rod is plugged into the corresponding clamping hole 36, automatically completing the anti-detachment connection between the mounting seat 31 and the mounting plate 33;

[0041] When the damaged charging monitor body 1 is to be urgently replaced, the rotating rod 44 is driven to rotate by rotating the twist wheel 46, and the rotating rod 44 reels the pull rope 45. The reeled pull rope 45 drives the slides 41 on both sides to move relative to each other, forcing the end of the clamping rod 42 to move into the mounting plate 33, quickly completing the separation of the mounting plate 33 and the mounting seat 31, thereby achieving the purpose of rapid disassembly of the charging monitor body 1.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
