Description

Technical Field

[0001] This utility model relates to the field of hoisting device technology; more specifically, it relates to a hoisting device for equipment maintenance. Background Technology

[0002] In chemical plant equipment maintenance, hoisting devices are frequently used to repair chemical machinery. A hoisting device is a mechanical system used for vertically lifting and horizontally moving heavy objects, mainly composed of a crane, lifting gear, and auxiliary components. It achieves precise load control through hydraulic, electric, or mechanical drives and is widely used in construction, manufacturing, logistics, and other fields. It features large lifting capacity and a wide operating range, and must strictly adhere to safety regulations to ensure operational stability and the safety of personnel and equipment.

[0003] Currently, existing hoisting devices suffer from several drawbacks during use. Due to their relatively fixed structures and lack of adjustment capabilities, when repairing tall objects, it's time-consuming and labor-intensive to select equipment of appropriate height. Furthermore, the need for multiple sets of equipment is inconvenient, reducing the device's applicability. Additionally, some existing devices may tilt or tip over when lifting heavy objects, potentially damaging the equipment. Therefore, a new hoisting device for equipment repair is urgently needed to address these issues. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a hoisting device for equipment maintenance, so as to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a hoisting device for equipment maintenance, comprising:

[0006] The frame has an internal adjustment structure, a lifting structure at the upper end of the adjustment structure, and support structures at the four corners of the frame.

[0007] The adjustment structure includes support rods, and there are two sets of support rods, with the two sets of support rods respectively inserted into the interior of the upper two sides of the frame;

[0008] The lifting structure includes a gantry frame, and the gantry frame is fixedly connected to the surface of the upper end of the two sets of support rods;

[0009] The support structure includes storage slots, and there are four sets of storage slots, with the four sets of storage slots respectively opened inside the surface at the four corners of the frame.

[0010] Preferably, a connecting block is fixedly connected to the surface of one end of each of the two sets of support rods that is close to each other, and an insertion slot is opened inside the upper outer surface of one end of each of the two sets of support rods, and multiple sets of insertion slots are provided. A first motor is installed inside the outer surface of both sides of one end of the frame, and a first lead screw is fixedly connected to the output section of each of the two sets of first motors. Insertion rods are inserted inside the outer surface of both sides of the upper end of one end of the frame, and a first spring is sleeved on the outer surface of each of the two sets of insertion rods. This design can drive the two sets of first lead screws to rotate by starting the two sets of first motors, thereby driving the connecting block to move up or down.

[0011] Preferably, the connecting block is sleeved on the outer surface of the two sets of first lead screws, the internal dimensions of the insertion slot are adapted to the external dimensions of one end of the insertion rod, the outer surface of the insertion rod is provided with a limiting ring, and the two ends of the first spring respectively abut against one side surface of the limiting ring and the inner wall surface of both sides of the upper end of the frame. This design allows the position of the support rod and the connecting block to be positioned when one end of the insertion rod is inserted into the insertion slot.

[0012] Preferably, the inner wall surfaces on both sides of the gantry frame are provided with moving grooves, and rotating gears are engaged with the interior of the two sets of moving grooves. A connecting rod is fixedly connected to the surface of the two sets of rotating gears on the side closest to each other, and a first bevel gear is fixedly connected to the middle position of the connecting rod. A moving plate is sleeved on the outer surface of the connecting rod. A second motor is installed inside the middle position of the moving plate, and a second bevel gear is fixedly connected to the output end of the second motor. A storage box is engaged with the interior of the outer surface of one side of the moving plate, and a third motor is installed inside one end of the storage box. A second lead screw is fixedly connected to the output end of the third motor, and a steel cable is sleeved on the outer surface of the second lead screw. This design allows the moving plate to move inside the gantry frame by rotating the rotating gears.

[0013] Preferably, the bottom surface of the moving groove is provided with a toothed groove, the outer surface of the rotating gear meshes with the outer surface of the toothed groove, the bottom surface of the second bevel gear meshes with the outer surface of one side of the first bevel gear, a T-shaped sliding groove is provided inside the side surface of the moving plate, and a T-shaped sliding block is fixedly connected to one side surface of the storage box, and the external dimensions of the T-shaped sliding block are adapted to the internal dimensions of the T-shaped sliding groove. This design makes the storage box more stable when moving inside the side surface of the moving plate, and avoids the storage box from detaching from the side surface of the moving plate.

[0014] Preferably, the inner wall surfaces on both sides of the upper end of the four sets of storage slots are hinged to support columns, and a movable rod is inserted into the inner surface of the upper outer surface of the support column. A second spring is sleeved on the surface of one end of the movable rod. A telescopic rod is inserted into the inner surface of the bottom surface of the four sets of support columns, and a positioning hole is opened in the inner surface of one side of the telescopic rod. Multiple positioning holes are provided. A positioning rod is inserted into the inner surface of one side of the lower end of the support column, and a third spring is sleeved on the outer surface of the positioning rod. The lower end of the telescopic rod is hinged to a support base. This design allows the telescopic rod to move inside the bottom surface of the support column.

[0015] Preferably, the inner surfaces of both ends of the frame are provided with positioning grooves, and multiple sets of positioning grooves are provided. The other end of the moving rod is fixedly connected to a rotating block, and a positioning block is fixedly connected to one side of the outer surface of one end of the rotating block. The external dimensions of the positioning block are adapted to the internal dimensions of the positioning groove. The outer surface of the moving rod is rectangular, and a limiting plate is fixedly connected to one end of the moving rod. The two ends of the second spring respectively abut against one side surface of the limiting plate and the inner surface of one side of the upper end of the storage groove. The internal dimensions of the positioning hole are adapted to the external dimensions of one end of the positioning rod. A limiting block is fixedly connected to the outer surface of the positioning rod. The two ends of the third spring respectively abut against one side surface of the limiting block and the inner surface of one side of the lower end of the support column. This design can position the support column after hinge rotation when the positioning block is inserted into the positioning groove at the corresponding position.

[0016] The technical effects and advantages of this utility model are as follows: This utility model moves two sets of insertion rods outward, causing one end of each set of insertion rods to disengage from the insertion slot. Then, two sets of first motors are started to drive two sets of first lead screws to rotate, causing the connecting block to move upward. Simultaneously, this causes two sets of support rods and the gantry frame to move upward in sync. When the support rods and the gantry frame have moved to a suitable height, the two sets of insertion rods can be released, allowing them to automatically reset themselves through the elasticity of the two sets of first springs. One end of each set of insertion rods is then inserted into the corresponding insertion slot. At this point, the positions of the two sets of support rods and the gantry frame can be positioned, thus allowing the lifting structure to be adjusted according to objects of different heights. This facilitates the lifting and maintenance of objects of different heights, eliminating the need for multiple sets of equipment and improving the applicability of the equipment to a certain extent.

[0017] By pulling the four sets of moving rods, the positioning block is disengaged from the positioning slot. Then, the hinged rotating support column is moved to the appropriate position. Releasing the four sets of moving rods allows them to automatically reset due to the elasticity of the second spring, moving the rotating block and simultaneously inserting the positioning block into the corresponding positioning slot. This positions the hinged rotation of the support column. Next, pulling the four sets of positioning rods disengages one end from the positioning hole. Then, pulling the telescopic rod downwards brings the bottom surface of the support base to the ground. Releasing the positioning rods allows them to automatically reset due to the elasticity of the third spring, inserting one end into the corresponding positioning hole. This positions the telescopic rod within the support column. Thus, the equipment is supported by the four sets of support columns and the telescopic rod, preventing tilting or tipping due to the weight of the suspended object, thus improving the equipment's practicality. Furthermore, its overall structure is simple and reasonable, highly practical, and easy to promote and apply. Attached Figure Description

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The hoisting device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1, as Figures 1-3 As shown in the figure, this embodiment proposes a hoisting device for equipment maintenance, including:

[0026] The frame 1 has an adjustment structure 2 inside, a lifting structure 3 at the upper end of the adjustment structure 2, and a support structure 4 at the four corners of the frame 1.

[0027] The adjustment structure 2 includes a support rod 21, and there are two sets of support rods 21, and the two sets of support rods 21 are respectively inserted into the interior of the upper two sides of the frame 1;

[0028] Two sets of support rods 21 are fixedly connected to each other on one side of their surfaces with connecting blocks 22. The upper outer surfaces of the two sets of support rods 21 are provided with insertion slots 23, and multiple sets of insertion slots 23 are provided. The inner surfaces of the outer surfaces on both sides of one end of the frame 1 are equipped with first motors 24, and the output sections of the two sets of first motors 24 are fixedly connected to first lead screws 25. Insertion rods 26 are inserted into the inner surfaces of the outer surfaces on both sides of the upper end of one end of the frame 1, and the outer surfaces of the two sets of insertion rods 26 are fitted with first springs 27.

[0029] The connecting block 22 is sleeved on the outer surface of the two sets of first lead screws 25. The internal dimensions of the insertion slot 23 are adapted to the external dimensions of one end of the insertion rod 26. The outer surface of the insertion rod 26 is provided with a limiting ring. The two ends of the first spring 27 respectively abut against one side surface of the limiting ring and the inner wall surface on both sides of the upper end of one end of the frame 1. This design allows the two sets of first lead screws 25 to drive the connecting block 22 to move up or down when rotating, and can simultaneously drive the two sets of support rods 21 to move up or down inside the frame 1. Furthermore, this design allows the insertion rod 26 to reset itself after moving through the elasticity of the first spring 27, so that one end of the insertion rod 26 is inserted into the corresponding position of the insertion slot 23, thereby positioning the position of the support rod 21.

[0030] The lifting structure 3 includes a gantry frame 31, and the gantry frame 31 is fixedly connected to the surface of the upper end of two sets of support rods 21;

[0031] The inner wall surfaces on both sides of the gantry frame 31 are provided with moving grooves 32, and the two sets of moving grooves 32 are engaged with rotating gears 33. The surfaces of the two sets of rotating gears 33 that are close to each other are fixedly connected with connecting rods 34, and the middle position of the connecting rods 34 is fixedly connected with a first bevel gear 35. The outer surface of the connecting rods 34 is fitted with a moving plate 36. The middle position of the moving plate 36 is installed with a second motor 37, and the output end of the second motor 37 is fixedly connected with a second bevel gear 38. The inner surface of one side of the outer surface of the moving plate 36 is engaged with a storage box 39, and the inner surface of one end of the storage box 39 is installed with a third motor 310. The output end of the third motor 310 is fixedly connected with a second lead screw 311, and the outer surface of the second lead screw 311 is fitted with a steel cable 312.

[0032] The bottom surface of the moving groove 32 is provided with a toothed groove. The outer surface of the rotating gear 33 meshes with the outer surface of the toothed groove. The bottom surface of the second bevel gear 38 meshes with the outer surface of one side of the first bevel gear 35. A T-shaped sliding groove is provided inside one side surface of the moving plate 36. A T-shaped sliding block is fixedly connected to one side surface of the storage box 39. The outer dimensions of the T-shaped sliding block are adapted to the inner dimensions of the T-shaped sliding groove. This design makes the rotating gear 33 more stable when moving inside the moving groove 32. At the same time, this design drives the second bevel gear 38 to rotate by starting the second motor 37, which can drive the first bevel gear 35 and the connecting rod 34 to rotate synchronously. The rotation of the connecting rod 34 drives the rotating gear 33 to move inside the moving groove 32, so that the moving plate 36 can move inside the gantry 31. This design makes the storage box 39 more stable when moving inside one side surface of the moving plate 36, and also prevents the storage box 39 from deflecting when moving.

[0033] The two sets of support rods 21 in this application, as well as all movable parts, require regular cleaning and maintenance, including but not limited to dust removal and lubrication.

[0034] Example 2, as Figure 4 and Figure 5 As shown, based on the same concept as the above embodiments, this embodiment also proposes:

[0035] The support structure 4 includes a storage slot 41, and there are four sets of storage slots 41, and the four sets of storage slots 41 are respectively opened inside the surface of the four corners of the frame 1.

[0036] The inner wall surfaces on both sides of the upper end of the four sets of storage slots 41 are hinged to support columns 42, and a moving rod 43 is inserted into the inner surface of the upper outer surface of the support column 42. A second spring 44 is sleeved on the surface of one end of the moving rod 43. A telescopic rod 45 is inserted into the inner surface of the bottom surface of the four sets of support columns 42. A positioning hole 46 is opened in the inner surface of one side of the telescopic rod 45. Multiple positioning holes 46 are provided. A positioning rod 47 is inserted into the inner surface of one side of the lower end of the support column 42. A third spring 48 is sleeved on the outer surface of the positioning rod 47. A support base 49 is hinged to the lower end of the telescopic rod 45.

[0037] The inner surface of the outer surfaces of both ends of the frame 1 is provided with positioning grooves, and there are multiple sets of positioning grooves. The other end of the moving rod 43 is fixedly connected to a rotating block, and a positioning block is fixedly connected to the outer surface of one side of the rotating block. The outer dimensions of the positioning block are adapted to the inner dimensions of the positioning groove. The outer surface of the moving rod 43 is rectangular, and a limiting plate is fixedly connected to one end of the moving rod 43. The two ends of the second spring 44 respectively abut against the inner surface of one side of the limiting plate and the inner surface of the upper side of the storage groove 41. The inner dimensions of the positioning hole 46 are adapted to the outer dimensions of one end of the positioning rod 47. A limiting block is fixedly connected to the outer surface of the positioning rod 47. The two ends of the third spring 48 respectively abut against the inner surface of one side of the limiting block and the inner surface of the lower side of the support column 42.

[0038] In this embodiment, the design allows the positioning block to be inserted into the positioning groove at the corresponding position to position the support column 42 after hinged rotation. At the same time, the support column 42 can drive the moving rod 43 to rotate synchronously when it is hinged. After the moving rod 43 moves, it can be reset by the elasticity of the second spring 44. The design also allows the positioning rod 47 to be reset by the elasticity of the third spring 48 after it moves. Thus, one end of the positioning rod 47 is inserted into the positioning hole 46 at the corresponding position, which can position the length of the telescopic rod 45 extending outward from the inside of the support column 42.

[0039] Working principle: When using the equipment, first move the equipment to the appropriate position, pull the moving rod 43 to disengage the positioning block from the positioning groove, then hinge the rotating support column 42 outward, causing the moving rod 43 and the rotating block to rotate. After the support column 42 has hinged and rotated to the appropriate position, release the moving rod 43, allowing it to self-position by the elasticity of the second spring 44, and causing the rotating block to move inward, simultaneously inserting the positioning block into the corresponding positioning groove. Then, pull the positioning rod 47 outward, causing one end of the positioning rod 47 to disengage from the positioning groove. Pull the telescopic rod 45 downwards into the positioning hole 46, so that the bottom surface of the support base 49 touches the ground. Then release the positioning rod 47, so that the positioning rod 47 returns to its original position by the elasticity of the third spring 48, and inserts one end of the positioning rod 47 into the corresponding positioning hole 46 to position the telescopic rod 45. Repeat the above operation until all four sets of support bases 49 touch the ground, thereby completing the support of the equipment. Then pull the two sets of insertion rods 26 outwards, so that one end of the insertion rod 26 disengages from the insertion slot 23. Then the two sets of... A motor 24 drives two sets of first lead screws 25 to rotate, causing the connecting block 22 to move upward. This causes the two sets of support rods 21 and the gantry frame 31 to move upward synchronously. When the support rods 21 and the gantry frame 31 have moved to a suitable height, the two sets of insertion rods 26 can be released, allowing the insertion rods 26 to automatically reset due to the elasticity of the first spring 27. One end of the insertion rod 26 is then inserted into the corresponding insertion slot 23. At this point, the positions of the support rods 21 and the gantry frame 31 can be positioned. Subsequently, the second motor 37 can be started to drive the second bevel gear 3. 8 rotates, simultaneously driving the first bevel gear 35 and the connecting rod 34 to rotate, and causing the rotating gear 33 to rotate inside the moving groove 32. When the rotating gear 33 rotates inside the moving groove 32, it can drive the moving plate 36 to move inside the gantry 31. Subsequently, the third motor 310 can be started as needed to drive the second lead screw 311 to rotate, causing the steel cable 312 to detach from the outer surface of the second lead screw 311 or rewound to the outer surface of the second lead screw 311, thereby enabling the hoisting device to be inspected. The above is the complete working principle of this utility model.

[0040] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
