Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coal mine transportation, in particular to a coal mine electromechanical transportation device. Background Art
[0002] The vast majority of coal mines in my country are underground. To transport coal from underground mines to the surface, a conveyor belt is required. Existing technology typically uses a motor-driven conveyor belt, which is suitable for long-distance transportation. These belts are typically driven by powered rollers, with several auxiliary rollers spaced apart to support the center. However, for very long transport distances, limited power and slack in the belt center prevent a single conveyor belt from being very long, making it difficult to transport coal over long distances. Therefore, deep underground mines require two or more conveyor belts to be connected, requiring specialized connecting equipment to connect adjacent belts.
[0003] The connection equipment currently used in the market often involves a complex and time-consuming series of steps to connect two adjacent conveyor belts. These steps require the manual installation and removal of multiple fasteners, bolts, and clamps to secure the connection. This process not only requires highly specialized skills and extensive experience, but is also susceptible to environmental factors such as space constraints, poor lighting, and dust accumulation, all of which can increase the difficulty and time required. This cumbersome installation and removal process not only increases labor costs but, more importantly, hinders work progress during installation and removal, resulting in reduced work efficiency. Utility Model Content
[0004] The purpose of this utility model is to propose and design a coal mine electromechanical transportation device that can realize the rapid connection and disassembly between two adjacent conveyor belts in order to solve the problem that the installation and disassembly process of the connecting equipment between two adjacent conveyor belts during coal transportation in existing mines is cumbersome and affects work efficiency.
[0005] The utility model provides a technical solution for solving the above technical problems, which is as follows: a coal mine electromechanical transport device, comprising two belt conveyors arranged at intervals, a connecting device provided between the two belt conveyors, the connecting device comprising a frame and a conveying mechanism, the conveying mechanism being mounted on the frame, a connecting frame provided at both ends of the frame, the connecting frame provided on both sides of the conveying mechanism, a limit block provided on the connecting frame, a limit drive assembly connected to the limit block, a limit slot provided on the belt conveyor, the limit block engaging with the limit slot, and a lifting adjustment assembly provided on the frame. The lifting adjustment assembly is used to adjust the height of the conveying mechanism to adapt to the height of the belt conveyor, the connecting frame is provided on both sides of the conveying mechanism for connecting the belt conveyor, and the limit drive assembly and the limit block are provided, so that an operator can operate the drive assembly to cause the limit block to engage with the limit slot of the belt conveyor, thereby achieving a quick locking connection with the belt conveyor, achieving a quick connection between the connecting device and the belt conveyor, and also achieving a quick connection when disassembling, thereby greatly improving the connection and disassembly speed of the connecting device and the belt conveyor, simplifying the operation, and thus improving the overall work efficiency.
[0006] Furthermore, the connecting frame is U-shaped so as to be snapped onto the belt conveyor from the side.
[0007] Furthermore, a mounting slot is provided on the side of the connecting frame close to the belt conveyor, in which a vertically arranged two-way threaded rod is rotatably connected. The top of the two-way threaded rod passes through the connecting frame and is fixedly connected to a knob. Two nut blocks arranged at intervals in the upper and lower directions are connected to the two-way threaded rod. A mounting plate is provided between the nut blocks and the belt conveyor. A support rod is hinged between the mounting plate and the two nut blocks. The side of the mounting plate facing the belt conveyor is fixedly connected to a limit block. When connection is required, by turning the knob, the two-way threaded rod is driven to rotate, thereby moving the two nut blocks. The nut blocks change the angle of the support rod, thereby giving the mounting plate an outward thrust, pushing the mounting plate to move closer to the belt conveyor, and then pushing the limit block to fit into the limit slot of the belt conveyor.
[0008] Furthermore, the conveying mechanism includes a power roller rotatably connected to one end of the frame, a transmission roller rotatably connected to the other end of the frame, a plurality of equally spaced auxiliary rollers rotatably connected between the power roller and the transmission roller, a conveyor belt being sheathed around the exterior of the power roller, the transmission roller, and the auxiliary rollers, and a first motor connected to one end of the power roller being disposed on the exterior of the frame. This mechanism works in conjunction with the belt conveyor without affecting the transportation of the coal.
[0009] Furthermore, a lifting and adjusting assembly is provided at the bottom of the frame. The lifting and adjusting assembly includes four threaded sleeves, which are rotatably connected to the four corners of the bottom of the frame. A first gear is fixedly connected to the outside of the threaded sleeves. A second motor is mounted on the frame. The output end of the second motor is connected to a second gear, which meshes with the first gear. A one-way threaded rod is connected to the threaded sleeves, and the bottom of each one-way threaded rod is fixedly connected to a support plate. The second motor drives the second gear to rotate, which in turn drives the first gear to rotate, which in turn drives the threaded sleeves to rotate, thereby causing the threaded sleeves to rise and fall along the one-way threaded rods. The threaded sleeves drive the frame and the conveying mechanism to rise and fall, thereby achieving height adjustment of the conveying mechanism and the connecting parts.
[0010] Furthermore, a rubber pad is provided at the bottom of the support plate.
[0011] Furthermore, a protective cover is provided at the bottom of the frame, and the first gear, the second gear and the second motor are all arranged inside the protective cover to play a protective role.
[0012] Furthermore, a guide rod is fixedly connected to the inside of the mounting groove, which is located on one side of the bidirectional threaded rod and is arranged parallel to the bidirectional threaded rod. The nut block is slidably connected to the guide rod to guide and limit the movement of the nut block, so that the nut block can move smoothly along the axial direction of the bidirectional threaded rod.
[0013] It can be seen from the above technical solutions that the present invention has the following advantages:
[0014] This solution provides a coal mine electromechanical transportation device, which adjusts the height of the conveying mechanism through a lifting and adjusting component to adapt to the height of the belt conveyor. By arranging connecting frames on both sides of the conveying mechanism for connecting to the belt conveyor, and arranging the limit drive component and the limit block, the operator can operate the drive component to make the limit block snap into the limit groove of the belt conveyor, thereby achieving a quick engagement connection with the belt conveyor and a quick connection between the connecting device and the belt conveyor. The same is true during disassembly, which greatly improves the connection and disassembly speed of the connecting device and the belt conveyor, simplifies the operation, and thus improves the overall work efficiency.

DETAILED DESCRIPTION

Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0023] like Figures 1 to 5 As shown, this specific embodiment provides a coal mine electromechanical transportation device, including two belt conveyors 1 arranged at intervals, a connecting device is provided between the two belt conveyors 1, the connecting device includes a frame 2 and a conveying mechanism 3, the conveying mechanism 3 is installed on the frame 2, and connecting frames 5 are provided at the front and rear ends of the frame 2. The connecting frames 5 are arranged on both sides of the conveying mechanism 3, and a limiting block 12 is provided on the connecting frame 5. The limiting block 12 is connected to the limiting drive assembly, a limiting groove 13 is provided on the belt conveyor 1, the limiting block 12 is engaged in the limiting groove 13, and a lifting adjustment assembly 4 is provided on the frame 2.
[0024] Among them, see Figure 5The conveying mechanism 3 includes a power roller 301 rotatably connected to one end of the frame 2, and a transmission roller 302 rotatably connected to the other end of the frame 2. A number of auxiliary rollers 303 rotatably connected between the power roller 301 and the transmission roller 302 are rotatably connected. A conveyor belt 304 is commonly sleeved on the outside of the power roller 301, the transmission roller 302 and the auxiliary roller 303. A first motor 305 connected to one end of the power roller 301 is provided on the outside of the frame 2, which cooperates with the belt conveyor 1 and does not affect the transportation of the coal mine.
[0025] Among them, see Figure 2 The connecting frame 5 is U-shaped so that it can be engaged with the belt conveyor 1 from the side. A mounting groove 6 is provided on the side of the connecting frame 5 near the belt conveyor 1. A vertically arranged two-way threaded rod 7 is rotatably connected in the mounting groove 6. The top of the two-way threaded rod 7 passes through the connecting frame 5 and is fixedly connected to a knob 8. Two nut blocks 9 arranged at intervals up and down are connected to the two-way threaded rod 7. The inside of the mounting groove 6 is fixedly connected with a guide rod 15. The guide rod 15 is located on one side of the two-way threaded rod 7 and is arranged parallel to the two-way threaded rod 7. The nut block 9 is slidably connected to the guide rod 15, and the movement of the nut block 9 is guided and limited, so that the nut block 9 can move smoothly along the axial direction of the two-way threaded rod 7. A mounting plate 10 is provided between the nut block 9 and the belt conveyor 1, and a support rod 11 is hinged between the mounting plate 10 and the two nut blocks 9. The mounting plate 10 is fixedly connected to a limit block 12 on the side facing the belt conveyor 1. When connection is required, by turning the knob 8, the bidirectional threaded rod 7 is driven to rotate, thereby moving the two nut blocks 9. The nut block 9 will change the angle of the support rod 11, thereby giving the mounting plate 10 an outward thrust, pushing the mounting plate 10 to move closer to the belt conveyor 1, and then pushing the limit block 12 to be stuck in the limit groove 13 of the belt conveyor 1.
[0026] Also, see Figure 3 and Figure 4 The lifting and adjusting assembly 4 is arranged at the bottom of the frame 2. The lifting and adjusting assembly 4 includes four threaded sleeves 401. The four threaded sleeves 401 are rotatably connected to the four corners of the bottom of the frame 2. The outside of the threaded sleeve 401 is fixedly connected to the first gear 402. A second motor 403 is installed on the frame 2. The output end of the second motor 403 is connected to the second gear 404. The second gear 404 is meshed with the first gear 402. A one-way threaded rod 405 is connected to the threaded sleeve 401. The bottom of each one-way threaded rod 405 is fixedly connected to a support plate 406. The second motor 403 drives the second gear 404 to rotate, the second gear 404 drives the first gear 402 to rotate, and the first gear 402 drives the threaded sleeve 401 to rotate, thereby causing the threaded sleeve 401 to rise and fall along the one-way threaded rod 405. The threaded sleeve 401 drives the frame 2 and the conveying mechanism 3 to rise and fall, thereby achieving height adjustment of the conveying mechanism 3 and the connecting member.
[0027] Its working principle is as follows: when in use, the height of the frame 2 is adjusted first, and the second gear 404 is driven to rotate by starting the second motor 403. When the second gear 404 rotates, it will simultaneously drive each first gear 402 to drive the threaded sleeve 401 to rotate, and then the one-way threaded rod 405 cooperates with the support plate 406 to drive the frame 2 to adjust the height, so that the height of the frame 2 is adapted to the height of the belt conveyor 1, so as to facilitate subsequent connection, by setting the adjusted conveying mechanism 3 between the two belt conveyors 1, and then respectively clamping the opposite ends of the two belt conveyors 1 between the two connecting frames 5 at both ends of the frame 2, and then turning the knob 8 to drive the two-way threaded rod 7 to rotate, thereby driving the two nut blocks 9 to move relative to each other, and then through the cooperation of the support rod 11, the mounting plate 10 and the limit block 12 are pushed toward the belt conveyor 1, and the limit block 12 will be inserted into the limit groove 13, thereby limiting and fixing the belt conveyor 1, completing the quick connection of the two belt conveyors 1.
