Description

Technical Field

[0001] The present invention relates to the technical field of equipment hoisting, and particularly relates to a hoisting device for mechanical equipment processing. Background Art

[0002] Hoisting refers to the general term for the installation and positioning of equipment by a crane or a hoisting mechanism. During the overhaul or repair process, various hoisting tools are used to lift equipment, workpieces, utensils, materials, etc., so that their positions change.

[0003] For example, in a large ring forging hot processing hoisting device with the Chinese patent publication number: CN117430003B, during the hoisting process, the cooperation of a chain and a hook is required to achieve the hoisting effect, and multiple chains also need to be connected to a support ring. When hoisting mechanical equipment in this way, since the sizes of different mechanical equipment are different, the chain needs to be pulled obliquely to adapt to the hoisted equipment at this time, and the chain may rub against the equipment at this time, thus affecting the service life of the chain; and the support ring and other structures provided in this way also occupy a large space and are not easy to transport.

[0004] Therefore, the present invention provides a hoisting device for mechanical equipment processing to solve the above problems. Summary of the Invention

[0005] In view of the above situation, in order to overcome the deficiencies of the prior art, the present invention provides a hoisting device for mechanical equipment processing to solve the above problem of affecting the service life of the device.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0009] A first hoisting frame is fixedly connected to the bottom of the fixed cross plate. A separating shaft is rotatably connected to the bottom of the first hoisting frame. A second hoisting frame is fixedly connected to the bottom of the separating shaft. Hoisting claws for hoisting mechanical equipment are connected to the bottoms of the first hoisting frame and the second hoisting frame.

[0011] Preferably, telescopic rods are fixedly connected to the opposite ends of the longer side of the fixed cross plate. The other ends of the telescopic rods are fixedly connected to the sliding frame.

[0012] The lifting mechanism includes two driving groups arranged in the driving frame. Each driving group consists of a driving shaft and a driven shaft. A first driving block is threadedly connected to the outer side wall of the driving shaft, and a second driving block is threadedly connected to the outer side wall of the driven shaft.

[0013] The first driving block is connected to the fixed cross plate through a first transmission rod. The two ends of the first transmission rod are respectively rotatably connected to the first driving block and the fixed cross plate. The second driving block is connected to the fixed cross plate through a second transmission rod. The two ends of the second transmission rod are respectively rotatably connected to the first driving block and the fixed cross plate.

[0014] Preferably, the driving shafts in the two driving groups are connected by a transmission belt. The driving shaft and the driven shaft in the same driving group are connected by two meshing rotating gears. A servo motor is fixedly connected to the fixed cross plate. The output end of the servo motor is connected to the driving shaft in any one of the driving groups. The servo motor can drive the connected driving shaft to rotate forward or backward.

[0015] Preferably, sliding openings are provided on both the first lifting frame and the second lifting frame. The length of the sliding opening on the first lifting frame is longer than the length of the second lifting frame. A distance-adjusting frame body is slidably connected in the sliding opening. A receiving shaft is rotatably connected to the distance-adjusting frame body.

[0016] A lifting rope is fixedly connected to the bottom end of the distance-adjusting frame body. A lifting block is fixedly connected to the bottom of the lifting rope. The lifting claw is fixedly connected to the bottom of the lifting block. A limiting hole is provided on the distance-adjusting frame body. The lifting rope is hollow, and the hollow position corresponds to the setting of the limiting hole.

[0017] Preferably, a limiting rope is wound around the outer side wall of the receiving shaft. The limiting rope is located in the hollow part of the lifting rope and extends along the setting direction of the lifting rope. A first limiting hook for limiting is fixedly connected to the bottom end of the limiting rope. A second limiting hook corresponding to the first limiting hook is fixedly connected to the lifting block.

[0018] Preferably, the distance-adjusting frame body is arranged in a horizontal U-shaped manner. The top end of the storage shaft extends towards the top of the distance-adjusting frame body. A limiting gear is fixedly connected to the outer side wall of the storage shaft. A limiting rack is slidably connected to the upper surface of the distance-adjusting frame body. The two limiting racks are meshed with the limiting gear. A limiting block is fixedly connected to the limiting rack. A limiting bayonet is formed on the side wall of the sliding port.

[0020] Preferably, the same rotating support rod is fixedly connected to the bottoms of the two sliding frames. The bottom end of the rotating support rod extends towards the separation shaft. A rotating push shaft is fixedly connected to the bottom end of the rotating support rod. A rotating arc groove for pushing the second lifting frame to rotate is formed on the separation shaft. The rotating arc groove is composed of a rotating section and a downward moving section. The rotating section is in an arc shape, and the downward moving section is arranged vertically.

[0021] The included angle between the head end and the tail end of the rotating section is a right angle. The length of the downward moving section corresponds to the distance that the lifting claw moves downward.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. Through the arranged distance-adjusting frame body in this solution, when hoisting the equipment, the distance-adjusting frame body can be pulled by the hoisting rope, so that multiple distance-adjusting frame bodies are respectively directly above the edges of the equipment. Then, by pulling the limiting rope, the limiting block can enter into the limiting bayonet to limit the position of the distance-adjusting frame body, preventing the hoisting device from being unstable during the hoisting process. Moreover, in this way, the hoisting rope can always hoist the equipment vertically, improving the service life of the device.

[0024] 2. Through the arranged separation shaft and the rotating arc groove in this solution, during the downward movement of the fixed cross plate, the second lifting frame and the first lifting frame can be staggered to form a cross shape, so as to facilitate hoisting of multiple positions of the equipment.

[0025] During the process of storing the hoisting device, the second lifting frame can be stored directly below the first lifting frame, which is convenient for storing the hoisting device and does not occupy a large space, facilitating other operations such as transportation.

[0037] Next, each embodiment of the present invention will be described in detail with reference to the attached Figures 1 to 10 Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0038] Embodiment 1

[0039] A hoisting device for machining mechanical equipment, as shown in the appendix Figure 1 - appendix Figure 10 As shown, it includes a gantry truss 2. Two symmetrically arranged support columns 1 are fixedly connected to the bottom of the gantry truss 2. The support columns 1 are used to support the gantry truss 2. The support columns 1 are placed on the ground to support the gantry truss 2. When the two support columns 1 and a gantry truss 2 are placed on the ground, they are arranged in an inverted U shape.

[0040] A fixed cross - plate 5 is connected below the gantry truss 2. The fixed cross - plate 5 can slide relative to the gantry truss 2. Limit blocks 4 are fixedly connected to the opposite sides of the gantry truss 2 that are perpendicular to the ground. A slide rail 3 is fixedly connected in the middle part between the two limit blocks 4. A sliding frame 6 is slidably connected to the outer side wall of the slide rail 3. The bottom ends of the two sliding frames 6 are fixedly connected between the opposite ends of the driving frame 8. After the hoisting device hoists the equipment, an external driving device is used to drive the two sliding frames 6 to move synchronously, so as to perform operations such as moving the hoisted equipment.

[0041] Embodiment 2

[0042] A driving frame 8 is connected between the middle positions of the gantry truss 2 and the fixed cross - plate 5. An elevating mechanism is arranged inside the driving frame 8. The elevating mechanism is used to drive the up - and - down movement of the fixed cross - plate 5. Telescopic rods 7 are fixedly connected to the opposite ends of the longer side of the fixed cross - plate 5. The other ends of the telescopic rods 7 are fixedly connected to the sliding frames 6. The telescopic rods 7 are used to limit the moving direction of the fixed cross - plate 5, so that the moving direction of the fixed cross - plate 5 is up - and - down movement.

[0043] Referring to the appendix Figure 3 , the elevating mechanism includes two driving groups arranged inside the driving frame 8. Each driving group is composed of a driving shaft 10 and a driven shaft 11. A first driving block 15 is threadedly connected to the outer side wall of the driving shaft 10, and a second driving block 14 is threadedly connected to the outer side wall of the driven shaft 11.

[0044] The first driving block 15 is connected to the fixed cross - plate 5 through a first transmission rod 16. The two ends of the first transmission rod 16 are respectively rotatably connected to the first driving block 15 and the fixed cross - plate 5. The second driving block 14 is connected to the fixed cross - plate 5 through a second transmission rod 17. The two ends of the second transmission rod 17 are respectively rotatably connected to the first driving block 15 and the fixed cross - plate 5.

[0045] The driving shafts 10 within the two driving groups are connected by a transmission belt 12. The driving shaft 10 and the driven shaft 11 within the same driving group are connected to each other by two meshing rotating gears 13. A servo motor 9 is fixedly connected to the fixed cross plate 5. The output end of the servo motor 9 is connected to the driving shaft 10 within any one of the driving groups. The servo motor 9 can drive the connected driving shaft 10 to rotate forward or backward.

[0046] The servo motor 9 can be driven in a wireless remote control manner to be turned on or off. When the servo motor 9 is turned on, it drives the driving shaft 10 within one of the driving groups to rotate. When the driving shaft 10 rotates, it drives the driven shaft 11 within the same driving group to rotate through the rotating gear 13. And the two driving groups are driven by the provided transmission belt 12, so that the two driving shafts 10 rotate synchronously.

[0047] And when the driving shaft 10 and the driven shaft 11 rotate synchronously, the first driving block 15 and the second driving block 14 are moved through the provided threads. It should be noted that when the hoisting device is not in use, the first transmission rod 16 and the second transmission rod 17 are inclined. When the hoisting device is in use, during the movement of the first driving block 15 and the second driving block 14, the top ends of the first transmission rod 16 and the second transmission rod 17 move in a direction perpendicular to them, thereby causing the fixed cross plate 5 to move downward.

[0048] Embodiment Three

[0049] A first hoisting frame 18 is fixedly connected to the bottom of the fixed cross plate 5. A separation shaft 35 is rotatably connected to the bottom of the first hoisting frame 18. A second hoisting frame 19 is fixedly connected to the bottom of the separation shaft 35. Hoisting claws 33 for hoisting mechanical equipment are connected to the bottoms of both the first hoisting frame 18 and the second hoisting frame 19.

[0050] Sliding openings 20 are provided on both the first hoisting frame 18 and the second hoisting frame 19. The length of the sliding opening 20 on the first hoisting frame 18 is longer than that of the second hoisting frame 19. A distance-adjusting frame body 21 is slidably connected within the sliding opening 20. A receiving shaft 24 is rotatably connected to the distance-adjusting frame body 21;

[0051] The bottom end of the distance-adjusting frame body 21 is fixedly connected to a hoisting rope 27. The bottom of the hoisting rope 27 is fixedly connected to a hoisting block 32. The hoisting claw 33 is fixedly connected to the bottom of the hoisting block 32. A limiting hole is provided on the distance-adjusting frame body 21. The hoisting rope 27 is hollow, and the hollow position corresponds to the setting of the limiting hole.

[0052] A limiting rope 28 is wound around the outer wall of the storage shaft 24. The limiting rope 28 is located in the hollow part of the hoisting rope 27 and extends along the setting direction of the hoisting rope 27. A first limiting hook 30 for limiting is fixedly connected to the bottom end of the limiting rope 28, and a second limiting hook 31 corresponding to the first limiting hook 30 is fixedly connected to the hoisting block 32.

[0053] Refer to the appendix Figure 4 - appendix Figure 8 Since the setting position of the distance adjustment frame 21 is usually relatively high, the operator can pull the hoisting rope 27 to move the distance adjustment frame 21 so that the distance adjustment frame 21 can be located directly above the edge of the equipment to be hoisted. At this time, manually pull the limiting rope 28 and limit the first limiting hook 30 through the second limiting hook 31. Since the limiting rope 28 needs to be pulled downward during the process of limiting the first limiting hook 30, and because the limiting rope 28 is wound around the outside of the storage shaft 24, the storage shaft 24 will rotate during the pulling process of the limiting rope 28.

[0054] The distance adjustment frame 21 is arranged in a flat U-shaped manner. The top end of the storage shaft 24 extends towards the top of the distance adjustment frame 21. A limiting gear 25 is fixedly connected to the outer wall of the storage shaft 24. A limiting rack 23 is slidably connected to the upper surface of the distance adjustment frame 21. The two limiting racks 23 are meshed with the limiting gear 25. A limiting block 22 is fixedly connected to the limiting rack 23. A limiting bayonet 29 is opened on the side wall of the sliding port 20. The limiting block 22 corresponds to the limiting bayonet 29.

[0055] A return spring 26 is provided between the limiting rack 23 and the distance adjustment frame 21. The number of the limiting racks 23 is two, which are respectively arranged on both sides of the limiting gear 25. The sliding direction of the limiting rack 23 is perpendicular to the inner wall of the sliding port 20.

[0056] As mentioned above, the limiting rope 28 will drive the storage shaft 24 to rotate during the limiting process. When the storage shaft 24 rotates, it will drive the two limiting racks 23 to move, so that the limiting blocks 22 on the limiting racks 23 move into the limiting bayonets 29 in the sliding port 20, thereby limiting the corresponding distance adjustment frame 21. In this way, multiple distance adjustment frames 21 are respectively moved to the edges of the equipment to be hoisted. When hoisting the equipment, the hoisting rope 27 can be straightened, so that it will not contact the equipment, and at the same time, the service life of the hoisting device is improved.

[0057] Embodiment Four

[0058] This embodiment is an embodiment that supplements Embodiment Three.

[0059] The bottoms of two sliding frames 6 are fixedly connected to the same rotating support rod 34. The bottom end of the rotating support rod 34 extends towards the separating shaft 35. The bottom end of the rotating support rod 34 is fixedly connected to a rotating push shaft 37. A rotating arc groove 36 for driving the second lifting frame 19 to rotate is formed on the separating shaft 35. The rotating arc groove 36 is composed of a rotating section and a downward moving section. The rotating section is in an arc shape, and the downward moving section is arranged vertically.

[0060] The included angle between the head end and the tail end of the rotating section is a right angle, and the length of the downward moving section corresponds to the distance that the lifting claw 33 moves downward.

[0061] When the fixed cross plate 5 moves downward, the separating shaft 35 will move downward, while the rotating push shaft 37 will not move downward. At this time, the rotating push shaft 37 will drive the second lifting frame 19 to rotate through the rotating section in the rotating arc groove 36, causing the second lifting frame 19 to rotate 90 degrees and forming a cross shape between the first lifting frame 18 and the second lifting frame 19. Then, when the fixed cross plate 5 continues to move downward, the rotating push shaft 37 will slide in the downward moving section, and the sliding distance of the downward moving section corresponds to the downward moving distance of the fixed cross plate 5. It should be noted that although the rotating section is arranged in a spiral shape, its vertical height can be ignored compared to the height of the downward moving section. The rotating section is only used to drive the second lifting frame 19 to rotate. Moreover, when hoisting the equipment, the fixed cross plate 5 needs to move downward a small distance to drive the second lifting frame 19 to rotate, facilitating the subsequent hoisting process. When not in use, the second lifting frame 19 will be directly below the first lifting frame 18, not occupying too much space, thus facilitating operations such as storage and transportation of the hoisting device.

[0062] It should be noted that in the description of the present invention, terms indicating directions or positional relationships such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings. This is only for convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, terms such as "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0063] In addition, it should also be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0064] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easily understood by those skilled in the art that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present invention.
