Description

Technical Field

[0001] This utility model belongs to the field of lifting equipment technology, and in particular relates to a suspension device for the maintenance of coal mine electromechanical equipment. Background Technology

[0002] Currently, when repairing coal mine electromechanical equipment, it is sometimes necessary to replace it with new equipment. This requires the equipment to be moved. For example, the dismantled equipment needs to be moved to a warehouse for disposal, or the new equipment needs to be moved to a transport vehicle that can move within the mine, and then the transport vehicle will transport the equipment to the installation location.

[0003] When transferring electromechanical equipment, some of which is quite heavy, a suspension device is needed for hoisting. Specifically, existing suspension devices include a cantilever beam at a certain height, with an electric hoist mounted on it that can move along the beam. The electric hoist includes a trolley and a winch mechanism. In use, the hook of the winch mechanism can hook onto the lifting lugs on the electromechanical equipment. After the electric hoist lifts the equipment to a certain height, it can be loaded and unloaded on the suspension device while moving along the cantilever beam. However, this setup requires the suspension device to be lifted to a certain height, which means the overall structure of the suspension device occupies considerable vertical space, making transportation inconvenient. Therefore, the existing technology still has drawbacks and shortcomings. Utility Model Content

[0004] The purpose of this utility model is to provide a suspension device for the maintenance of coal mine electromechanical equipment, so as to solve the problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows: A suspension device for maintaining electromechanical equipment in coal mines includes a suspension trolley with two vertically opposite retractable outriggers mounted on it. The top of each retractable outrigger is a telescopic end. A crossbeam is installed between the telescopic ends of the two outriggers. An electrically operated telescopic rod is installed between the crossbeam and the suspension trolley. A fixed pulley mechanism is installed on one side of the crossbeam. An inverted U-shaped frame is fixedly mounted on the top surface of the crossbeam. A horizontally distributed cantilever is provided on the side of the inverted U-shaped frame away from the fixed pulley mechanism. The cantilever beam has one end fixedly connected to an inverted U-shaped frame, and the other end extends outside the suspended vehicle. A sliding trolley that can move along the cantilever beam is also installed on the cantilever beam. A pulley mechanism that is opposite to the fixed pulley mechanism is installed on the sliding trolley. A lifting rope is provided between the pulley mechanism and the fixed pulley mechanism. One end of the lifting rope passes around the pulley mechanism and is equipped with a hook. The other end of the lifting rope passes through the inverted U-shaped frame and around the fixed pulley mechanism and is connected to the bottom of the telescopic outrigger.

[0006] Furthermore, a receiving box with an opening on the top surface is installed on the suspension vehicle located below the cantilever beam. The receiving box has an opening on the side away from the telescopic outrigger and is equipped with a stop bar. The stop bar is a threaded rod, and both ends of the stop bar are slidably connected to the receiving box through vertically opened slides on the receiving box. Both ends of the stop bar also pass through the receiving box through slides. Locking sleeves are fitted and threadedly connected to the stop bar on both sides outside the slides.

[0007] Furthermore, each of the retractable outriggers includes vertically distributed branch pipes, the bottom end of which is connected to the suspension vehicle, and a reinforcing rod is installed between the branch pipe and the suspension vehicle. A movable rod is also slidably connected inside each branch pipe, and the top end of the movable rod is located outside the branch pipe and connected to the crossbeam.

[0008] Furthermore, a positioning rod is installed between the two branch pipes located below the fixed pulley mechanism, and the end of the lifting rope away from the hook is connected to the positioning rod.

[0009] Furthermore, there are multiple positioning rods, which are distributed at equal intervals from high to low, and both ends of each positioning rod are rotatably connected to the branch pipe. The end of the lifting rope away from the hook is hooked to the positioning rod through a hook.

[0010] Furthermore, the fixed pulley mechanism is installed at both ends of the crossbeam. There are two sets of pulley mechanisms, which are respectively positioned opposite to the fixed pulley mechanism. Each set of pulley mechanisms is connected to the fixed pulley mechanism by a suspension rope. One end of the suspension rope is equipped with a hook, and the other end of the suspension rope is hooked to the positioning rod.

[0011] Furthermore, the fixed pulley mechanism includes a pulley frame mounted on a crossbeam, a pulley rotatably connected inside the pulley frame, the axial line of the pulley being parallel to the crossbeam, and an inverted U-shaped plate mounted on the pulley frame covering the pulley.

[0012] Furthermore, a limit block is fixedly installed at the end of the cantilever beam away from the inverted U-shaped frame.

[0013] Furthermore, the electric telescopic rod is a hydraulic cylinder, and the hydraulic cylinder is connected to a hydraulic pump station installed on the suspension vehicle.

[0014] The beneficial effects of this utility model by adopting the above technical solution are as follows: In use, this invention allows for the loading and unloading of electromechanical equipment on a suspended crane by coordinating the extension and retraction of the electric telescopic rod with the movement of the sliding trolley along the cantilever beam. Specifically, when lifting or lowering the electromechanical equipment, this invention utilizes the extension and retraction of the electric telescopic rod and the movement of the sliding trolley as power sources. Compared to the prior art of installing an electric hoist on the cantilever beam, this eliminates the need for a winch mechanism on the cantilever beam, thus reducing the load on the cantilever beam and improving its structural stability. Furthermore, when transporting the suspended device of this invention, the electric telescopic rod can be retracted to lower the overall height of the suspended device, facilitating transportation.

[0017] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0018] like Figures 1 to 5As shown, this utility model provides a suspension device for the maintenance of coal mine electromechanical equipment, including a suspension vehicle 4. Specifically, the suspension vehicle 4 includes a horizontally arranged frame 41, with several wheels 42 rotatably connected to both sides of the frame 41, and a handle 43 installed at one end of the frame 41. Two vertically distributed telescopic outriggers 3 are installed on the suspension vehicle 4, with the top of the telescopic outriggers 3 being the telescopic end. A crossbeam 5 is installed between the telescopic ends of the two telescopic outriggers 3, and an electric telescopic rod 1 is installed between the crossbeam 5 and the suspension vehicle 4. Specifically, the two ends of the electric telescopic rod 1 are hinged to the crossbeam 5 and the frame 41 of the suspension vehicle 4, respectively. The electric telescopic rod 1 can be configured as a hydraulic cylinder, which is connected to a hydraulic pump station 11 installed on the suspension vehicle 4. The hydraulic pump station 11 is the power source for the extension and retraction of the electric telescopic rod 1. In addition, to improve the stability of the suspension device during operation, vertically distributed and telescopic hydraulic outriggers can also be installed at the four corners of the suspension vehicle 4.

[0019] Furthermore, a fixed pulley mechanism 6 is installed on one side of the crossbeam 5, and an inverted U-shaped frame 2 is fixedly installed on the top surface of the crossbeam 5. A horizontally distributed cantilever beam 7 is provided on the side of the inverted U-shaped frame 2 away from the fixed pulley mechanism 6. The cantilever beam 7 is an I-beam. One end of the cantilever beam 7 is fixedly connected to the inverted U-shaped frame 2, and the other end of the cantilever beam 7 extends to the outside of the suspended vehicle 4. A sliding trolley 17 that can move along the cantilever beam 7 is also installed on the cantilever beam 7. Specifically, the electric hoist in the prior art... After removing the winch mechanism, the sliding trolley 17 is formed, which can move automatically along the cantilever beam 7. The sliding trolley 17 is equipped with a pulley mechanism 12 that is opposite to the fixed pulley mechanism 6. A suspension rope 13 is provided between the pulley mechanism 12 and the fixed pulley mechanism 6. One end of the suspension rope 13 passes around the pulley mechanism 12 and is equipped with a hook 14. The other end of the suspension rope 13 passes through the inverted U-shaped frame 2 and passes around the fixed pulley mechanism 6 and is connected to the bottom of the telescopic support leg 3.

[0020] Specifically, in use, when it is necessary to hoist the electromechanical equipment onto the suspended crane 4, the telescopic end of the electric telescopic rod 1 is extended and retracted, while the sliding trolley 17 moves along the cantilever beam 7, allowing the hook 14 to hook onto the lifting lugs on the electromechanical equipment. Then, the telescopic end of the electric telescopic rod 1 continues to extend to lift the electromechanical equipment to a certain height. Next, the sliding trolley 17 moves along the cantilever beam 7 towards the position close to the inverted U-shaped frame 2. At the same time, the extension and retraction of the electric telescopic rod 1 controls the height at which the electromechanical equipment is lifted, ensuring that the electromechanical equipment is always higher than the suspended crane 4, until the electromechanical equipment is above the suspended crane 4. Then, the telescopic end of the electric telescopic rod 1 is retracted, and with manual assistance, the electromechanical equipment can be smoothly lowered onto the suspended crane 4 for transfer. Similarly, when it is necessary to unload the electromechanical equipment from the suspended crane 4, the extension and retraction of the electric telescopic rod 1 and the movement of the sliding trolley 17 along the cantilever beam 7 are used in conjunction to unload the electromechanical equipment from the suspended crane 4.

[0021] In summary, when in use, this utility model allows for the loading and unloading of electromechanical equipment on the suspended vehicle 4 through the coordinated extension and retraction of the electric telescopic rod 1 and the movement of the sliding trolley 17 along the cantilever beam 7. Specifically, when lifting and lowering the electromechanical equipment, this utility model utilizes the extension and retraction of the electric telescopic rod 1 and the movement of the sliding trolley 17 as power sources. Compared to the prior art where an electric hoist is installed on the cantilever beam 7, a winch mechanism is not required on the cantilever beam 7, thus reducing the load on the cantilever beam 7 to a certain extent and improving its structural stability. Furthermore, when transporting the suspended device of this utility model, the electric telescopic rod 1 can be retracted to reduce the overall height of the suspended device, facilitating transportation.

[0022] Furthermore, such as Figures 1 to 4 As shown, a receiving box 8 with an open top surface is installed on the suspension vehicle 4 located below the cantilever beam 7. The receiving box 8 is located at the end of the suspension vehicle 4 away from the handle 43. A stop bar 15 is set and installed on the side of the receiving box 8 away from the telescopic outrigger 3. The stop bar 15 is horizontally set and is a threaded rod. Both ends of the stop bar 15 are slidably connected to the receiving box 8 through vertically opened slides 81 on the receiving box 8. Both ends of the stop bar 15 also pass through the receiving box 8 through the slides 81. Locking sleeves 16 are fitted and threadedly connected to the stop bar 15 on both sides outside the slides 81. Specifically, in the initial state, the stop bar 15 is located in the receiving box 8. The bottom of the container 8 is located in the container. During use, the electric telescopic rod 1 is extended and retracted, and the sliding trolley 17 moves along the cantilever beam 7. With human assistance, the electromechanical equipment can be hoisted to the position of the container 8, so that the bottom of the electromechanical equipment is located inside the container 8. Then, by sliding the stop bar 15 to a suitable height, the locking sleeves 16 located on both sides of the slide rail 81 are rotated to abut against the container 8 to fix the position of the stop bar 15. This can restrict the position of the electromechanical equipment to a certain extent to prevent the electromechanical equipment from slipping off the suspension vehicle 4 during the transfer process.

[0023] The specific configuration of the retractable outrigger 3 is as follows: Figures 1 to 3 As shown, each telescopic outrigger 3 includes a vertically distributed branch pipe 31. The bottom end of each branch pipe 31 is connected to the suspension vehicle 4, and a reinforcing rod 32 is installed between each branch pipe 31 and the suspension vehicle 4. The reinforcing rod 32 can improve the connection strength between the branch pipe 31 and the suspension vehicle 4 at the connection position to ensure the structural stability of the telescopic outrigger 3. Each branch pipe 31 is also slidably connected to a movable rod 33. The top end of the movable rod 33 is located outside the branch pipe 31 and connected to the crossbeam 5. Specifically, when the telescopic end of the electric telescopic rod 1 is telescopic, the movable rods 33 of the two telescopic outriggers 3 can move synchronously along the branch pipe 31 to ensure the stability of the cantilever beam 7 during the lifting process.

[0024] The specific arrangement of connecting the end of the lifting rope 13 away from the hook 14 to the bottom of the retractable outrigger 3 is as follows: Figures 1 to 3 As shown, a positioning rod 9 is installed between the two branch pipes 31 located below the fixed pulley mechanism 6. Specifically, a support seat 91 is installed at both ends of the positioning rod 9, and the support seat 91 is fixedly mounted on the branch pipe 31. The end of the lifting rope 13 away from the hook 14 is connected to the positioning rod 9 for fixation.

[0025] Furthermore, such as Figures 1 to 3 As shown, there are multiple positioning rods 9, which are evenly distributed from high to low. Both ends of each positioning rod 9 are rotatably connected to the branch pipe 31. The end of the lifting rope 13 away from the hook 14 is hooked to the positioning rod 9 through the hook 10. This makes it easy to install and remove the lifting rope 13 from the positioning rod 9. In addition, since there are multiple positioning rods 9, during use, depending on the height of the electromechanical equipment being transferred, the end of the lifting rope 13 away from the hook 14 can be fixed to the positioning rod 9 in a suitable position to ensure the applicability of this utility model.

[0026] Furthermore, such as Figure 1 and Figure 3 As shown, fixed pulley mechanisms 6 are installed at both ends of the crossbeam 5. There are two sets of pulley mechanisms 12, which are respectively positioned opposite to the fixed pulley mechanisms 6. Each set of pulley mechanisms 6 and fixed pulley mechanisms 12 is provided with a lifting rope 13. One end of each lifting rope 13 is equipped with a hook 14, and the other end of each lifting rope 13 is hooked to the positioning rod 9 through a hook 10. That is, there are two sets of hooks 14. In this way, the electromechanical equipment can be lifted from two points during use.

[0027] The specific configuration of the fixed pulley mechanism 6 is as follows: Figure 1 , Figure 3 and Figure 5 As shown, the fixed pulley mechanism 6 includes a pulley frame 61 mounted on the crossbeam 5. A pulley 62 is rotatably connected inside the pulley frame 61. The axial line of the pulley 62 is parallel to the crossbeam 5, and an inverted U-shaped plate 63 mounted on the pulley frame 61 covers the pulley 62. Specifically, in use, the lifting rope 13 passes over the top of the pulley 62, and the top of the pulley 62 is higher than the top surface of the crossbeam 5 to prevent the crossbeam 5 from abrading the lifting rope 13; while the inverted U-shaped plate 63 can prevent the lifting rope 13 from slipping off the pulley 62.

[0028] Furthermore, such as Figures 1 to 3 As shown, a limiting block 71 is fixedly installed at the end of the cantilever beam 7 away from the inverted U-shaped frame 2. During use, the limiting block 71 can prevent the sliding trolley 17 from falling off the end of the cantilever beam 7 away from the inverted U-shaped frame 2.
