Description

Technical Field

[0001] This invention relates to the field of electromechanical installation technology, specifically a lifting device for electromechanical installation in coal mines. Background Technology

[0002] The underground environment in coal mines is complex, and it is often necessary to raise or lower equipment or personnel to different heights during the installation, testing, or maintenance of electromechanical equipment. Currently, most commonly used lifting devices are single-stage lifting structures, such as simple winches combined with suspended baskets or fixed hydraulic lifting platforms.

[0003] Chinese Patent Publication No. CN 119660539 B discloses a lifting device specifically for electromechanical installation in coal mines, belonging to the field of electromechanical installation technology. It includes a support frame and two hydraulic winches fixedly installed within the support frame. Multiple support legs are threaded onto the lower side of the support frame. Steel wire ropes are wound around the outer sides of the two hydraulic winches, and the lower ends of the steel wire ropes are jointly fixedly connected to a fixing plate. A first connecting plate is rotatably connected to the lower side of the fixing plate. This invention, under the action of the first connecting plate, the second connecting plate, and multiple protective ropes, completes the clamping and fixing operation of electromechanical equipment. It is simple in structure, robust and reliable, and under the action of the rotating drum and rotating rod, the actual size of each protective rope can be adjusted, thus enabling the connection operation of electromechanical equipment of different shapes and sizes.

[0004] However, the above solution still has the following problems:

[0005] The limited lifting stroke makes it difficult to adapt to certain underground work scenarios that require a wide range or segmented height adjustment;

[0006] The lack of an effective multi-level buffer mechanism results in large vibrations of the equipment and internal loads during lifting, starting, stopping, or encountering sudden impacts, leading to insufficient stability and safety, which can easily cause equipment damage or measurement errors.

[0007] The overall structure is often relatively simple, with low functional integration and poor protection. Downhole dust and moisture can easily corrode the core mechanical and electrical control components.

[0008] Some devices employ complex electrical systems, which are costly and face reliability challenges in the harsh electrical environment of mines, resulting in numerous inconveniences.

[0009] Therefore, the present invention requires the design of a lifting device specifically for the installation of electromechanical equipment in coal mines to solve the aforementioned problems. Summary of the Invention

[0010] The purpose of this invention is to provide a special lifting device with multiple buffers, multi-stage lifting capabilities, compact structure, good protection, and stable operation, so as to solve the problems mentioned in the background art.

[0011] To achieve the above objectives, the present invention provides the following technical solution: a lifting device specifically for electromechanical installation in coal mines, comprising an electromechanical installation protective box, and further comprising:

[0012] The internal lifting mechanism is located inside the electromechanical installation protective box and is used for one-time lifting.

[0013] The external lifting mechanism is located on top of the electromechanical installation protective box and is used for secondary lifting;

[0014] The buffer seat is located between the internal lifting mechanism and the external lifting mechanism and is used to buffer the two lifting operations.

[0015] The external lifting mechanism includes a winding roller and a mine detection device. A top support platform is installed on the top of the electromechanical installation and protection box. A limit frame is installed on the top of the top support platform. The winding roller is rotatably connected inside the limit frame. A connecting rope is sleeved on the outside of the winding roller. The mine detection device is installed at one bottom end of the connecting rope.

[0016] The internal lifting mechanism includes a bottom positioning frame and a first rotating support plate. A lifting platform is installed inside the electromechanical installation protective box and at the bottom of the buffer seat. A bottom positioning frame is installed inside the electromechanical installation protective box and below the lifting platform. Two first rotating support plates and two second rotating support plates are rotatably connected between the bottom positioning frame and the lifting platform. The first and second rotating support plates are staggered and rotatably connected. The buffer seat contains equidistantly distributed second springs and damping shock absorbers. One lifting operation: When the work platform needs to be raised, multiple electric telescopic rods located on the bottom positioning frame are activated. The electric telescopic rods extend, pushing the push rod. Because the push rod is hinged to the positioning frame on the second rotating support plate, it forces the two sets of staggered first and second rotating support plates to rotate upwards and unfold around their connection point. This process is similar to... Similar to the principle of a scissor lift, the top lifting platform, along with the buffer seat and top support platform installed on it, are lifted upwards as a whole, achieving the first large-scale lifting. During or after the first lifting, if vibration or impact occurs, the force is transmitted to the buffer plate through the support column. The buffer plate presses down, causing the sliding plate to compress the first and second springs inside the buffer seat and activating the energy dissipation effect of the damping shock absorber, achieving the first buffer. When the impact is large, the buffer plate descends along the limiting groove until it is blocked. At this time, the side limiting seat directly bears the force, forming a hard limit and secondary buffer. The external lifting mechanism located at the top works independently. The drive motor is started, which drives the drive shaft and winding roller to rotate through the transmission belt, thereby releasing or winding the connecting rope, realizing the precise descent or lifting of the mine detection equipment suspended at its end. This process is the second independent lifting, used for the final precise positioning of the equipment.

[0017] In a preferred embodiment of the present invention, a first fixing block is fixedly connected to the top of the top support platform and to one side of the limiting frame, and a second fixing block is fixedly connected to the top of the top support platform and to the other side of the limiting frame. A conveyor belt protective cover is fixedly connected to the top of the second fixing block, and a drive motor is fixedly connected to the side of the conveyor belt protective cover away from the limiting frame. Both ends of the winding roller are fixedly connected to a drive shaft, one of which extends into the interior of the first fixing block and is rotatably connected to the interior of the first fixing block.

[0018] In a preferred embodiment of the present invention, the inside of the conveyor belt protective cover is provided with a transmission belt for use with the drive motor. The output end of the drive motor is connected to the driving pulley of the transmission belt, and one end of the transmission shaft is connected to the driven pulley of the transmission belt. This ensures that the winding roller is driven to rotate normally by the operation of the drive motor and the cooperation of the transmission belt, thus ensuring the completion of one lifting operation.

[0019] In a preferred embodiment of the present invention, a first spring is fixedly connected inside the buffer seat and around the second spring. A sliding pressure plate located inside the buffer seat is fixedly connected to the top of both the first and second springs. A buffer pressure plate extending to the outer side of the top of the sliding pressure plate is fixedly connected to the top of each sliding pressure plate. The top of each buffer pressure plate is fixedly connected to the bottom of the support column. The damping shock absorber is located inside the corresponding second spring.

[0020] In a preferred embodiment of the present invention, a limiting rod extending into the bottom positioning frame is rotatably connected between each of the two first rotating support plates. A second reinforcing connecting plate is fixedly connected above the limiting rod and between the two first rotating support plates. Equally spaced electric telescopic rods are rotatably connected inside each of the second reinforcing connecting plates. A push rod is fixedly connected to the output end of each electric telescopic rod. A positioning frame is fixedly connected between each of the two second rotating support plates. One end of each push rod is rotatably connected to the positioning frame. The operation of the multiple electric telescopic rods drives the push rod to one side. Limited by the positioning frame, this causes the staggered first and second rotating support plates to gradually rotate upwards, thereby providing support for the lifting platform.

[0021] In a preferred embodiment of the present invention, the bottom of each buffer seat is fixedly connected to the top of the lifting platform, and a first reinforcing connecting plate is installed between the two second rotating support plates and below the positioning frame.

[0022] In a preferred embodiment of the present invention, a wireless transceiver is fixedly connected to one side of the drive motor, a main control board is fixedly connected inside the wireless transceiver, and a control chip is fixedly connected to the outside of the main control board. The drive motor, the wireless transceiver, and the electric telescopic rod are all electrically connected to the control chip. The control chip is used to control the operation of the drive motor, the wireless transceiver, and the electric telescopic rod. The overall structure does not use a large number of electrical devices to assist in operation, thereby saving the overall use and installation costs.

[0023] In a preferred embodiment of the present invention, auxiliary positioning plates are fixedly connected to both sides of the bottom positioning frame at equal intervals. The interior of each auxiliary positioning plate is threaded with positioning bolts extending to the inner wall of the bottom of the electromechanical installation protective box. The internal lifting mechanism is normally connected to the electromechanical installation protective box through the cooperation of multiple positioning bolts and auxiliary positioning plates, thereby improving the stability of normal operation of the equipment.

[0024] In a preferred embodiment of the present invention, side limiting seats are installed on the top of the buffer seat and on both sides of the buffer pressure plate. The top of the buffer seat has a limiting groove that matches the buffer pressure plate. The buffer pressure plate slides normally into the buffer seat through the limiting groove until it can no longer move. At this time, the two side limiting seats support the top support platform as a whole, achieving a primary buffer protection effect. The buffer pressure plate moves into the buffer seat, causing the sliding pressure plate to squeeze multiple sets of springs at the bottom. The first spring, the second spring, and the damping shock absorber work together to achieve a secondary buffer protection effect, which not only extends the stability of the equipment but also provides a buffer protection effect for some parts of the equipment, thus extending the service life of the equipment. Ventilation holes are equally distributed on both sides of the buffer seat.

[0025] In a preferred embodiment of the present invention, a field positioning roller is fitted around the outside of the connecting rope, and a positioning rod is fixedly connected to the axis of the field positioning roller. The length of the positioning rod is changed according to the working scenario. Before lifting operations, the positioning rod is used to perform positioning processing in conjunction with the field. The installation height of the field positioning roller is adjusted according to the scenario requirements, and the connecting rope is wound around the outside of the field positioning roller to cooperate with the subsequent lifting operations of the mine inspection equipment.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] This invention includes an electromechanical installation protection box, mine detection equipment, and a bottom positioning frame. When the work platform needs to be raised, multiple electric telescopic rods located on the bottom positioning frame are activated. The electric telescopic rods extend, pushing the push rod. Since the push rod is hinged to the positioning frame on the second rotating support plate, it forces the two sets of interlocking first and second rotating support plates to rotate upwards around their connection point. This process is similar to the principle of a scissor lift, lifting the top lifting platform and the buffer seat and top support platform installed on it as a whole, achieving the first large-scale lifting. During or after a lifting process, if vibration or impact occurs, the force will be transmitted to the buffer pressure plate through the support column. The buffer pressure plate presses down, causing the sliding pressure plate to compress the first and second springs inside the buffer seat. It also stimulates the energy dissipation of the damping shock absorber to achieve the initial buffering. When the impact is large, the buffer plate descends along the limiting groove until it is blocked. At this time, the side limiting seat directly bears the force, forming a hard limit and secondary buffering. The external lifting mechanism located at the top works independently. The drive motor is started, and the drive shaft and winding roller are driven to rotate through the transmission belt, thereby releasing or winding the connecting rope to achieve the precise descent or lifting of the mine detection equipment suspended at its end. This process is the second independent lifting, used for the final precise positioning of the equipment. Before operation, the direction of the connecting rope can be fixed according to the underground environment by the positioning rod and the on-site positioning roller to increase stability. The entire mechanical structure is placed in the electromechanical installation protective box for physical protection. The wireless signal transceiver and control chip can realize remote control and reduce on-site manual operation. Attached Figure Description

[0054] Please see Figures 1-4 In this scheme, auxiliary positioning plates 5 are fixedly connected to both sides of the bottom positioning frame 3 at equal intervals. The auxiliary positioning plates 5 are threaded with positioning bolts 51 extending to the inner wall of the bottom of the electromechanical installation protective box 1. Through the cooperation of multiple positioning bolts 51 and auxiliary positioning plates 5, the internal lifting mechanism is normally connected to the electromechanical installation protective box 1, which improves the stability of normal operation of the equipment.

[0055] Please see Figures 1-7In this design, side limiting seats 42 are installed on the top of the buffer seat 4 and on both sides of the buffer pressure plate 41. The top of the buffer seat 4 has a limiting groove that matches the buffer pressure plate 41. The buffer pressure plate 41 slides normally into the buffer seat 4 through the limiting groove until it can no longer move. At this time, the two side limiting seats 42 support the top support platform 13 as a whole, which provides a primary buffer protection effect. The buffer pressure plate 41 moves into the buffer seat 4, which drives the sliding pressure plate 47 to squeeze the multiple sets of springs at the bottom. The first spring 44, the second spring 45 and the damping shock absorber 46 work together to provide a secondary buffer protection effect, which not only extends the stability of the equipment but also provides a buffer protection effect for some parts of the equipment, thus extending the service life of the equipment.

The length of the positioning rod 23 can be changed according to the operation scenario. Before lifting operations, the positioning rod 23 is used to perform positioning processing on site. The installation height of the field positioning roller 22 is adjusted according to the needs of the scenario. The connecting rope 21 is wrapped around the outside of the field positioning roller 22 to cooperate with the subsequent lifting operation of the mine detection equipment 2.

[0057] Please see Figures 1-7 The working principle of this invention is as follows:

[0058] This invention comprises an electromechanical installation protective box 1, a mine detection device 2, and a bottom positioning frame 3. During use:

[0059] First lifting operation: When the work platform needs to be raised, multiple electric telescopic rods 37 located on the bottom positioning frame 3 are activated. The electric telescopic rods 37 extend, pushing the push rod 38 to move. Since the push rod is hinged to the positioning frame 35 on the second rotating support plate 32, it forces the two sets of staggered first rotating support plates 31 and second rotating support plates 32 to rotate upward and unfold around their connection point. This process is similar to the principle of a scissor lift, lifting the top lifting platform 11 and the buffer seat 4 and top support platform 13 installed on it upward as a whole, realizing the first large-scale lifting operation.

[0060] Buffering: During or after a lifting or lowering process, if vibration or impact occurs, the force will be transmitted to the buffer plate 41 through the support column 12. The buffer plate 41 presses down, causing the sliding plate 47 to compress the first spring 44 and the second spring 45 inside the buffer seat 4, and activating the energy dissipation function of the damping shock absorber 46 to achieve the initial buffering. When the impact is large, the buffer plate descends along the limiting groove until it is blocked. At this time, the side limiting seat 42 directly bears the force, forming a hard limit and secondary buffering.

[0061] Secondary lifting: The external lifting mechanism at the top operates independently. Starting the drive motor 18 drives the drive shaft 17 and winding roller 24 to rotate via the transmission belt, thereby releasing or rewinding the connecting rope 21. This achieves precise descent or elevation of the mine inspection equipment 2 suspended at its end. This process constitutes the second independent lifting, used for the final precise positioning of the equipment.

[0062] Auxiliary positioning and protection: Before operation, the positioning rod 23 and the on-site positioning roller 22 can be used to fix the direction of the rope lead-out according to the downhole environment, thereby increasing stability. The entire mechanical structure is placed in the electromechanical installation and protection box 1 for physical protection. The wireless signal transceiver 19 and control chip can realize remote control, reducing on-site manual operation.

[0063] The control chip is used to control the operation of the drive motor 18, the wireless signal transceiver 19 and the electric telescopic pole 37. The overall structure does not use a large number of electrical devices to assist in operation, thus saving the overall use and installation costs.

[0064] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
