Description

Technical Field

[0001] This invention relates to the field of equipment hoisting technology, and more specifically to a mechanical equipment processing and hoisting device. Background Technology

[0002] Lifting refers to the general term for the installation and positioning of equipment using cranes or hoisting mechanisms. During inspection or maintenance, various lifting tools are used to lift equipment, workpieces, tools, materials, etc., so as to change their position.

[0003] For example, Chinese Patent Publication No. CN117430003B describes a large ring forging hot-working hoisting device. This method requires the coordinated use of chains and hooks to achieve the hoisting effect, with multiple chains connected to support rings. When hoisting machinery using this method, since different pieces of machinery vary in size, the chains need to be tilted and pulled to fit the equipment being hoisted. This may cause friction between the chains and the equipment, affecting their lifespan. Furthermore, the support rings and other structures in this method occupy a significant amount of space, making them difficult to transport.

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

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

[0015] Preferably, both the first and second lifting frames are provided with sliding openings. The length of the sliding opening on the first lifting frame is longer than the length of the second lifting frame. An adjustable frame body is slidably connected inside the sliding opening, and a storage shaft is rotatably connected to the adjustable frame body.

[0016] The bottom end of the adjustable frame is fixedly connected to a hoisting rope, the bottom of the hoisting rope is fixedly connected to a hoisting block, the lifting claw is fixedly connected to the bottom of the hoisting block, the adjustable frame has a limit hole, the hoisting rope is hollow, and the position of the hollow corresponds to the setting of the limit hole.

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

[0018] Preferably, the adjustable frame is arranged in a flat U-shape, the top end of the storage shaft extends towards the top of the adjustable frame, a limiting gear is fixedly connected to the outer wall of the storage shaft, a limiting rack is slidably connected to the upper surface of the adjustable frame, the two limiting racks are meshed with the limiting gear, a limiting block is fixedly connected to the limiting rack, a limiting slot is opened on the side wall of the sliding port, and the limiting block and the limiting slot correspond to each other;

[0023] 1. This solution, through the setting of adjustable-width frames, allows multiple adjustable-width frames to be pulled by the hoisting ropes during equipment hoisting, positioning them directly above the edge of the equipment. Then, the limit rope is pulled, causing the limit blocks to enter the limit slots, limiting the position of the adjustable-width frames and preventing instability of the hoisting device during hoisting.

[0037] The following will refer to the attached reference. Figures 1 to 10 The various embodiments of the present invention will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0038] Example 1

[0039] A mechanical equipment processing and hoisting device, as shown in the attached... Figure 1 -Appendix Figure 10 As shown, it includes a gantry truss 2, and 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 the gantry truss 2 are placed on the ground, they are arranged in an inverted U-shape.

[0040] A fixed horizontal plate 5 is connected to the lower part of the gantry truss 2. The fixed horizontal plate 5 can slide relative to the gantry truss 2. Limiting 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 to the middle part of the two limiting blocks 4. Sliding frames 6 are slidably connected to the outer wall of the slide rail 3. The bottom ends of the two sliding frames 6 are fixedly connected to the opposite ends of the drive frame 8. After the hoisting device hoists the equipment, the two sliding frames 6 are driven to move synchronously by an external drive device, thereby moving the hoisted equipment and performing other operations.

[0041] Example 2

[0042] A drive frame 8 is connected between the gantry truss 2 and the fixed horizontal plate 5. The drive frame 8 contains a lifting mechanism that drives the fixed horizontal plate 5 to move up and down. Telescopic rods 7 are fixedly connected to both ends of the longer side of the fixed horizontal plate 5, and the other end of each telescopic rod 7 is fixedly connected to a sliding frame 6. The telescopic rods 7 limit the direction of movement of the fixed horizontal plate 5, ensuring that the fixed horizontal plate 5 moves up and down.

[0043] See attached document Figure 3 The lifting mechanism includes two drive groups disposed within the drive frame 8. Each drive group consists of a drive shaft 10 and a driven shaft 11. A first drive block 15 is threadedly connected to the outer side wall of the drive shaft 10, and a second drive block 14 is threadedly connected to the outer side wall of the driven shaft 11.

[0044] The first drive block 15 is connected to the fixed horizontal plate 5 via a first transmission rod 16. The two ends of the first transmission rod 16 are rotatably connected to the first drive block 15 and the fixed horizontal plate 5, respectively. The second drive block 14 is connected to the fixed horizontal plate 5 via a second transmission rod 17. The two ends of the second transmission rod 17 are rotatably connected to the first drive block 15 and the fixed horizontal plate 5, respectively.

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

[0046] The servo motor 9 can be driven wirelessly to turn on or off. When the servo motor 9 is turned on, it drives the drive shaft 10 in one of the drive groups to rotate. When the drive shaft 10 rotates, it drives the driven shaft 11 in the same drive group to rotate through the rotating gear 13. The two drive groups are driven by the transmission belt 12, so that the two drive shafts 10 rotate synchronously.

[0047] Furthermore, when the drive shaft 10 and driven shaft 11 rotate synchronously, the first drive block 15 and the second drive block 14 move 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 drive block 15 and the second drive 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 horizontal plate 5 to move downward.

[0048] Example 3

[0049] The bottom of the fixed horizontal plate 5 is fixedly connected to a first lifting frame 18, the bottom of the first lifting frame 18 is rotatably connected to a separation shaft 35, the bottom of the separation shaft 35 is fixedly connected to a second lifting frame 19, and the bottom of both the first lifting frame 18 and the second lifting frame 19 are connected to lifting claws 33 for lifting mechanical equipment.

[0050] Both the first hoisting frame 18 and the second hoisting frame 19 are provided with sliding openings 20. The length of the sliding opening 20 on the first hoisting frame 18 is longer than the length of the second hoisting frame 19. An adjustable frame body 21 is slidably connected inside the sliding opening 20, and a storage shaft 24 is rotatably connected to the adjustable frame body 21.

[0051] The bottom end of the adjustable frame 21 is fixedly connected to a hoisting rope 27, and the bottom of the hoisting rope 27 is fixedly connected to a hoisting block 32. The lifting claw 33 is fixedly connected to the bottom of the hoisting block 32. Limiting holes are opened on the adjustable frame 21. The hoisting rope 27 is hollow, and the position of the hollow 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. A second limiting hook 31 corresponding to the first limiting hook 30 is fixedly connected to the hoisting block 32.

[0053] See attached document Figure 4 -Appendix Figure 8 Since the adjustable frame 21 is usually positioned high, the operator can move it by pulling the hoisting rope 27, positioning it directly above the edge of the equipment to be hoisted. Then, the operator manually pulls the limiting rope 28, using the second limiting hook 31 to limit the first limiting hook 30. During the limiting process of the first limiting hook 30, the limiting rope 28 needs to be pulled downwards. Because the limiting rope 28 is wound around the outside of the storage shaft 24, pulling the limiting rope 28 will cause the storage shaft 24 to rotate.

[0054] The adjustable frame 21 is arranged in a flat U-shape. The top of the storage shaft 24 extends towards the top of the adjustable frame 21. The outer wall of the storage shaft 24 is fixedly connected to the limiting gear 25. The upper surface of the adjustable frame 21 is slidably connected to the limiting rack 23. The two limiting racks 23 are meshed with the limiting gear 25. The limiting rack 23 is fixedly connected to the limiting block 22. The side wall of the sliding port 20 is provided with the limiting slot 29. The limiting block 22 and the limiting slot 29 correspond to each other.

[0055] A return spring 26 is provided between the limiting rack 23 and the adjusting frame 21. There are two limiting racks 23, which are respectively set 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, during the limiting process, the limiting rope 28 drives the storage shaft 24 to rotate. When the storage shaft 24 rotates, it drives the two limiting racks 23 to move, thereby causing the limiting blocks 22 on the limiting racks 23 to move into the limiting slots 29 in the sliding opening 20, thus limiting the corresponding adjustable frame 21. In this way, multiple adjustable frame 21s are moved to the edge of the hoisted equipment. When hoisting the equipment, the hoisting rope 27 can be straightened to prevent contact with the equipment and also improve the service life of the hoisting device.

[0057] Example 4

[0058] This embodiment is a supplement to Embodiment 3.

[0059] The bottom of the two sliding frames 6 is fixedly connected to the same rotating support rod 34. The bottom end of the rotating support rod 34 extends towards the separation shaft 35. The bottom end of the rotating support rod 34 is fixedly connected to a rotating push shaft 37. The separation shaft 35 is provided with a rotating arc groove 36 for pushing the second hoisting frame 19 to rotate. The rotating arc groove 36 consists of a rotating section and a downward section, wherein the rotating section is arc-shaped and the downward section is vertically arranged.

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

[0061] When the fixed horizontal plate 5 moves downward, the separating shaft 35 moves downward, while the rotating push shaft 37 does not. At this time, the rotating push shaft 37 drives 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, as the fixed horizontal plate 5 continues to move downward, the rotating push shaft 37 slides in the downward section. The sliding distance of the downward section corresponds to the downward distance of the fixed horizontal plate 5. It should be noted that although the rotating section is spiral-shaped, its vertical height is negligible compared to the height of the downward section. The rotating section is only used to drive the second lifting frame 19 to rotate. Furthermore, when lifting the equipment, the fixed horizontal plate 5 needs to move downward a short distance to drive the second lifting frame 19 to rotate, facilitating the subsequent lifting process. When not in use, the second lifting frame 19 will be located directly below the first lifting frame 18, without taking up too much space, thus facilitating the storage and transportation of the lifting device.

[0062] It should be noted that in the description of this invention, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0063] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0064] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles 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 such changes or substitutions will all fall within the scope of protection of the present invention.
