Description

Technical Field

[0001] This utility model relates to the field of jack technology, specifically to a jack storage cart. Background Technology

[0002] A jack is a small lifting device that uses a rigid lifting component as its working device to lift heavy objects within its stroke via a top support or bottom claw. When working in a workshop, maintenance personnel frequently need to use jacks to replace couplings on large equipment or heavy machinery. Due to the large work area and the different locations each time a coupling is replaced, workers need to frequently move the jack and its accessories, including safety supports, extension rods, rotating handles, dust caps, quick couplings, etc. This process consumes a significant amount of time and manpower for moving, counting, and even locating accessories, greatly impacting work efficiency.

[0003] Therefore, there is an urgent need for a special trolley for storing jacks and their accessories, which can store jacks and their accessories at a fixed point, making them easy to move and reducing the amount of labor required for workers when moving jacks and their accessories. Summary of the Invention

[0004] This invention addresses the problem of frequent jack and accessory transfers during coupling replacement in workshops, which consumes a significant amount of time and physical labor for maintenance personnel. It provides a jack storage trolley that facilitates coupling disassembly while also providing storage space for the jack and its accessories, greatly reducing the labor time and intensity for maintenance personnel.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A jack storage cart includes:

[0007] The frame has wheels at its bottom and at least two layers of shelves inside; the frame is used to form the skeleton of the trolley.

[0008] A height adjustment assembly is located between two adjacent shelves and is used to adjust the height of the trolley.

[0009] A support unit is slidably mounted on the top of the trolley and is used to horizontally fix the jack.

[0010] A positioning unit is included, which is detachably connected to the support unit. The positioning unit is used to fix the relative position of the jack and the coupling. The jack is used to disassemble the coupling.

[0011] Furthermore, the frame includes two layers of shelves: a first layer on top and a second layer on the bottom, with side panels attached to the edges of the second layer. The second layer is used to store the jack and its accessories.

[0012] Furthermore, a support unit is rotatably mounted on the first layer plate. The support unit includes a sliding part slidably mounted on the top of the trolley and a fixing part connected to the sliding part. The fixing part matches the jack base. When the coupling is disassembled using a jack, the jack and the support unit slide relative to the trolley.

[0013] Furthermore, a rotating part is rotatably provided on the first layer plate, and a sliding groove matching the sliding part is provided on the rotating part. A handle is provided on one side of the rotating part. The handle is used for rotating the rotating part and moving the trolley as a whole.

[0014] Furthermore, the sliding part and the fixed part together form an L-shaped plate, with the horizontal part of the L-shaped plate being the sliding part and the vertical part being the fixed part. The jack is horizontally positioned on one side of the fixed part, with the lifting part of the jack facing the trolley side.

[0015] Furthermore, the positioning unit includes a positioning plate, which is square in shape and has a U-shaped hole for holding the coupling. The width of the U-shaped hole matches the width of the coupling shaft hole. The positioning plate is used to fix the coupling.

[0016] Furthermore, the positioning plate and the fixing part are arranged parallel to each other and connected by a screw, with a nut fitted on the screw. Tightening the nut adjusts the distance between the positioning plate and the fixing part.

[0017] Furthermore, the length of the screw is less than the length of the second layer plate. When it is not necessary to remove the coupling, the screw can be stored on the second layer plate of the trolley.

[0018] Furthermore, the second layer is longer than the first layer. Higher components, such as jacks, can be placed on the protruding portion of the second layer.

[0019] Furthermore, the height adjustment component is a telescopic rod. A total of four telescopic rods are provided between the first and second shelves. These telescopic rods support the second shelf on one hand and adjust the height between the second and first shelves on the other.

[0020] The beneficial effects of this utility model through the above technical solution are as follows:

[0021] This utility model features a height adjustment component, a support unit, and a positioning unit on a trolley frame. The height adjustment component allows for adjustment of the trolley's height, the support unit horizontally fixes the jack, and the positioning unit fixes the relative position of the jack and the coupling. Pushing the trolley allows for easy disassembly of the coupling, avoiding the need for maintenance personnel to frequently move the jack while working in the workshop, thus greatly saving workers' labor time. At the same time, the jack and its accessories can be easily moved with the trolley, saving time spent searching for spare parts. Attached Figure Description

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0028] like Figures 1-4 As shown, this embodiment provides a jack storage trolley, including a frame 1, a height adjustment component 2, a support unit 3, and a positioning unit 4. The frame 1 is used to form the trolley skeleton, the height adjustment component 2 is used to adjust the height of the trolley, the support unit 3 is used to horizontally fix the jack 5 to the top of the trolley, and the positioning unit 4 is used to fix the position between the jack 5 and the coupling 6.

[0029] The frame 1 can be welded from metal rods such as shaped steel and channel steel. The bottom of the frame 1 is provided with traveling wheels 11. At least two layers of shelves are provided inside the frame 1. In this embodiment, the frame 1 has two layers of shelves. The first shelf 12 is located on the upper layer of the frame 1, and the second shelf 13 is located on the lower layer of the frame 1. The length of the second shelf 13 is greater than the length of the first shelf 12. The edge of the second shelf 13 is connected with a side plate. The second shelf 13 is used to store the jack and its accessories. A rotating part 14 is rotatably provided on the first shelf 12. In one possible implementation, the first shelf 12 is square. A bearing is provided at the center of the first shelf 12. A rotating shaft matching the bearing is fixedly provided at the bottom of the rotating part 14.

[0030] To facilitate the control of the trolley, a handle 15 is provided on one side of the rotating part 14. Specifically, the handle 15 is welded from a metal rod. Pushing the handle 15 can control the rotation of the rotating part 14 and move the trolley.

[0031] The height adjustment component 2 is located between two adjacent shelf plates and is used to adjust the height of the trolley. In this embodiment, the height adjustment component 2 is located between the first shelf plate 12 and the second shelf plate 13. The height adjustment component 2 can be a telescopic rod. The height adjustment component 2 includes a sleeve and a sliding rod slidably disposed in the sleeve. A fastener is provided between the sliding rod and the sleeve. The fastener is used to fix the position of the sliding rod in the sleeve after the height is adjusted. Specifically, a total of four telescopic rods are provided between the second shelf plate 13 and the first shelf plate 12. The telescopic rods support the second shelf plate 13 on one hand and adjust the height between the second shelf plate 13 and the first shelf plate 12 on the other hand.

[0032] The support unit 3 is slidably mounted on the top of the trolley and is used to horizontally fix the jack 5. The support unit 3 includes a sliding part 31 slidably mounted on the top of the trolley and a fixing part 32 connected to the sliding part 31. The fixing part 32 matches the base of the jack 5. In this embodiment, the jack 5 is a hydraulic jack. Specifically, the base of the jack 5 and the fixing part 32 are connected by bolts. The sliding part 31 and the fixing part 32 together form an L-shaped plate. The horizontal part of the L-shaped plate is the sliding part 31, and the vertical part of the L-shaped plate is the fixing part 32. The rotating part 14 is provided with a groove that matches the sliding part 31 of the L-shaped plate. This allows the jack 5 to be horizontally fixed, so that the lifting part of the jack 5 can be aligned with the coupling 6.

[0033] The positioning unit 4 is detachably connected to the support unit 3. The positioning unit 4 is used to fix the relative position of the jack 5 and the coupling 6. Specifically, the positioning unit 4 includes a screw 41, a nut 42 and a positioning plate 43. The positioning plate 43 is square and has a U-shaped hole for holding the coupling 6. The width of the U-shaped hole matches the width of the shaft hole of the coupling 6. Specifically, both the fixing part 32 and the positioning plate 43 have a circular hole for the screw 41 to pass through. The positioning plate 43 and the fixing part 32 are arranged in parallel and connected by the screw 41. The nut 42 is sleeved on the screw 41. By turning the nut 42, the distance between the positioning plate 43 and the fixing part 32 can be adjusted.

[0034] To facilitate the storage of trolley parts, the length of the screw 41 is less than the length of the second layer plate 13. When there is no need to remove the coupling 6, the screw 41 can be removed and placed on the second layer plate 13 of the trolley. Since the length of the second layer plate 13 is greater than the length of the first layer plate 12, taller parts such as the jack 5 can be placed on the protruding part of the second layer plate 13. At this time, the upper layer of the trolley can be used to store parts normally, which reduces the height of the trolley and saves space.

[0035] The principle of this utility model:

[0036] When it is necessary to remove coupling 6, push the trolley to coupling 6, turn handle 15 to make rotating part 14 drive support unit 3 to rotate 90 degrees, adjust the height of first plate 12 through height adjustment component 2, so that the lifting part of jack 5 is aligned with the center position of coupling 6, loosen nut 42, remove positioning plate 43, place positioning plate 43 on connecting shaft 61 at the rear end of coupling 6, adjust the position of screw 41, use nut 42 to fix the distance between positioning plate 43 and fixing part 32, turn on jack 5, lifting part of jack 5 is pushed out, positioning plate 43 drives coupling 6 to move away from connecting shaft 61, thereby removing coupling 6 from connecting shaft 61.

[0037] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model.
