Description

Technical Field

[0001] This utility model relates to the field of gantry crane technology, and in particular to a lifting and maintenance device for compressor repair. Background Technology

[0002] Light-duty mobile gantry cranes, also known as simple gantry cranes, light-duty gantry cranes, light-duty mobile gantry cranes, or light-duty mobile portal cranes, are used when repairing air compressors. Some components of the air compressor are heavy and difficult to move manually, so a gantry crane is needed.

[0003] Therefore, in the prior art, there is a tooling for air compressor maintenance, with publication number CN222361844U. When in use, the user pulls the control panel, which causes the control column to slide within the rotating groove and rotate the rotating rod. The rotating rod then rotates the gear, causing the gear to drive the limiting plate to compress the spring via the toothed plate, and thus the fixed block enters the inner cavity of the movable groove. The user then pulls the stop lever, which slides upward within the limiting groove. The user inserts the lifting chain into the limiting lever's inner cavity and pulls the stop lever in the opposite direction. After the stop lever moves to the bottom of the limiting groove, the user releases the control panel. The force released after the spring compression pushes the limiting plate to move in the opposite direction, simultaneously causing the fixed block to insert into the inner cavity of the fixed groove. At the same time, the limiting plate, via the toothed plate, drives the gear to rotate in the opposite direction, and through the control column, the control panel resets, completing the operation.

[0004] In this device, because the stop lever is located close to the lifting device, after the stop lever fixes the lifting chain, it will drive the compressor to move closer to the lifting device. During the process of the lifting device moving the compressor, if it encounters a rough road surface or brakes or starts, the inertial motion of the compressor may cause it to collide with the lifting device. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art, and to propose a lifting and maintenance device for compressor maintenance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a lifting and maintenance device for compressor repair, comprising a lifting device, a guide rail fixedly connected to one inner side of the lifting device, two connecting plates symmetrically distributed around the guide rail fixedly connected to one side of the lifting device, a sliding groove plate arranged parallel to the guide rail fixedly connected to the other side of the connecting plate, an mounting plate provided on the other side of the two sliding groove plates, the two ends of the mounting plate being slidably connected to the sliding grooves on the two sliding groove plates respectively, a limiting frame located between the two sliding groove plates fixedly connected to one side of the mounting plate, a slider slidably connected to the guide rail, a telescopic sleeve rod hinged to one side of the slider for passing through the limiting frame, and a clamping mechanism for holding the lifting chain provided at the telescopic end of the telescopic sleeve rod.

[0007] Preferably, the clamping structure includes a U-shaped clamping frame fixedly connected to the telescopic end of the telescopic sleeve rod, with a clamping rod hinged to one side of the open end of the U-shaped clamping frame, and a pin inserted through the clamping rod on the other side of the open end of the U-shaped clamping frame.

[0008] Preferably, the fixed end of the telescopic sleeve is threaded with an adjusting bolt, and the adjusting bolt abuts against the telescopic end of the telescopic sleeve.

[0009] Preferably, the sliding groove of the sliding plate is provided with a plurality of positioning holes, and positioning bolts are threaded through both ends of the mounting plate, with two positioning bolts respectively inserted into two positioning holes of equal height.

[0010] Preferably, a plurality of positioning holes are arranged in an array along the sliding direction of the mounting plate.

[0011] Preferably, a storage frame for placing the clamping structure is fixedly connected to one side of the lifting device and at the end of the guide rail.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting guide rails and sliders, the telescopic sleeve can move on the lifting device. When the telescopic sleeve is in a horizontal state, the clamping mechanism can be used to clamp the lifting chain and fix the lifting chain at a position close to the middle of the lifting device. Furthermore, the horizontal position of the clamping mechanism can be adjusted by the extension and retraction of the telescopic sleeve, which improves the accuracy of compressor position control during the lifting process and avoids the risk of collision.

[0014] 2. In this utility model, by setting up a storage frame, a dedicated storage space is provided for the clamping structure. When the lifting device is not used, the clamping structure can be stored in the storage frame to protect the clamping structure and prevent it from being damaged when idle.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figure 1-5 As shown, a lifting and maintenance device for compressor repair includes a lifting device 1. A guide rail 3 is fixedly connected to one inner side of the lifting device 1. Two connecting plates 4 are fixedly connected to one side of the lifting device 1, symmetrically distributed around the guide rail 3. A sliding groove plate 5, parallel to the guide rail 3, is fixedly connected to the other side of the connecting plate 4. An mounting plate 9 is provided on the other side of the two sliding groove plates 5. The two ends of the mounting plate 9 are slidably connected to the sliding grooves on the two sliding groove plates 5. A limiting frame 7 located between the two sliding groove plates 5 is fixedly connected to one side of the mounting plate 9. A slider 10 is slidably connected to the guide rail 3. A telescopic sleeve 2 for passing through the limiting frame 7 is hinged to one side of the slider 10. A clamping mechanism for holding the lifting chain is provided at the telescopic end of the telescopic sleeve 2.

[0024] In this technical solution, the slider 10 slides on the guide rail 3, driving the telescopic sleeve 2 to move. After the telescopic end of the telescopic sleeve 2 passes through the limiting frame 7, the slider 10 continues to slide, causing the telescopic sleeve 2 to rotate relative to the slider 10 until the slider 10 moves to face the limiting frame 7. At this time, the telescopic sleeve 2 passes through the limiting frame 7 and its telescopic end moves to a position away from the lifting device 1. Due to the gravity distribution, the telescopic end of the telescopic sleeve 2 is heavier, causing the other end of the telescopic sleeve 2 to tilt upward, so that the other end of the telescopic sleeve 2 abuts against the top inside the limiting frame 7. With the support of the bottom inside the limiting frame 7, the position of the telescopic sleeve 2 is restricted, thereby restricting the height of the clamping structure.

[0025] In addition, by setting up the sliding groove plate 5, the mounting plate 9 moves up and down within the sliding groove plate 5, thereby changing the height position of the limit frame 7, which can adjust the horizontal height of the clamping structure.

[0026] like Figure 4 As shown, the clamping structure includes a U-shaped clamping frame 12 fixedly connected to the telescopic end of the telescopic sleeve rod 2. A clamping rod 13 is hinged to one side of the open end of the U-shaped clamping frame 12, and a pin 14 that passes through the clamping rod 13 is inserted into the other side of the open end of the U-shaped clamping frame 12. An adjusting bolt 8 is threadedly connected to the fixed end of the telescopic sleeve rod 2, and the adjusting bolt 8 abuts against the telescopic end of the telescopic sleeve rod 2.

[0027] In this technical solution, the opening of the U-shaped clamping frame 12 is used to place the lifting chain, and after the lifting chain is placed, the clamping rod 13 is driven to rotate by the operator 1 so that it cooperates with the U-shaped clamping frame 12 to clamp the lifting chain. The pin 14 inserts and fixes the clamping rod 13 and the U-shaped clamping frame 12 together to prevent the clamping rod 13 from being accidentally released during the lifting process.

[0028] Furthermore, by setting the adjusting bolt 8, when it is necessary to adjust the telescopic length of the telescopic sleeve 2, the adjusting bolt 8 is loosened by rotating it, so that the rod end of the adjusting bolt 8 is separated from the telescopic end of the telescopic sleeve 2. At this time, the operator controls the telescopic end of the telescopic sleeve 2 to slide, thereby adjusting the horizontal position of the clamped lifting chain, so that the lifted compressor can be brought closer to the middle or one side of the lifting device.

[0029] like Figure 5 As shown, the sliding groove of the sliding plate 5 has several positioning holes 15. Both ends of the mounting plate 9 are threaded with positioning bolts 11. The two positioning bolts 11 are respectively inserted into two positioning holes 15 of equal height. The several positioning holes 15 are arranged in an array along the sliding direction of the mounting plate 9.

[0030] In this technical solution, several positioning holes 15 provide multiple adjustable positioning positions for the mounting plate 9. When it is necessary to adjust the position of the mounting plate 9 on the sliding groove plate 5, first loosen the positioning bolts 11 so that the mounting plate 9 can slide freely in the sliding groove. According to the actual maintenance needs, after sliding the mounting plate 9 to the appropriate position, tighten the positioning bolts 11 so that they are inserted into the corresponding equal-height positioning holes 15 respectively.

[0031] like Figure 2 As shown, a storage frame 6 for placing the clamping structure is fixedly connected to one side of the lifting device 1 and at the end of the guide rail 3.

[0032] In this technical solution, when placing the clamping structure, first slide the slider 10 downwards so that the telescopic sleeve 2 slides out of the limiting frame 7, then slide the slider 10 upwards so that the telescopic sleeve 2 passes through the space between the limiting frame 7 and the lifting device 1 and moves upwards until it moves close to the storage frame 6. At this time, the operator controls the telescopic sleeve 2 to tilt from one side of the storage frame 6 and continue upwards until the clamping structure is above the storage frame 6. Then, straighten the telescopic sleeve 2 and slide the slider 10 downwards to drive the clamping structure downwards, so that the clamping structure falls into the storage frame 6.

[0033] Working principle: In use, first control the mounting plate 9 to rise and fall within the sliding groove plate 5 to determine the height of the limiting frame 7. Then control the slider 10 to slide on the guide rail 3, driving the telescopic sleeve 2 to move. The telescopic end of the telescopic sleeve 2 passes through the limiting frame 7. Afterward, as the slider 10 continues to slide, it will drive the telescopic sleeve 2 to rotate relative to the slider 10 until the slider 10 moves to be directly opposite the limiting frame 7. At this time, the telescopic sleeve 2 passes through the limiting frame 7. With the support of the bottom inside the limiting frame 7, the other end of the telescopic sleeve 2 abuts against the top inside the limiting frame 7, and the position of the telescopic sleeve 2 is restricted, thereby restricting the height of the clamping structure. Then, the lifting chain is placed into the U-shaped clamping frame 12, the clamping rod 13 is rotated and fixed with the pin 14, thereby fixing the position of the lifting chain. To adjust the horizontal position of the lifted compressor, loosen the adjusting bolt 8 to separate the rod end of the adjusting bolt 8 from the telescopic end of the telescopic sleeve 2. At this time, the operator controls the telescopic end of the telescopic sleeve 2 to slide, thereby adjusting the horizontal position of the clamped lifting chain.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
