Description

Technical Field

[0001] This application relates to the technical field of cranes, and in particular to a slide rail fixing structure. Background Art

[0002] Gantry cranes are usually used for lifting and moving various types of goods and materials. They are commonly used in places such as docks, factories, warehouses, and construction sites, and can effectively improve the loading and unloading efficiency and operation efficiency of goods.

[0003] In an anti-shake gantry crane mentioned in an existing Chinese published patent (authorization announcement number: CN216235685U), when the motor winds up two traction belts, with the cooperation of the sliding plate, the limiting plate, and the connecting components, the two traction belts will only move in the vertical direction at this time, and will not shake significantly under the action of wind and the inertia of the goods, improving safety and reducing the difficulty of the winding work at the same time.

[0004] When the sliding plate of the existing gantry crane grabs and lifts materials, slide rails are mostly arranged on both sides of the support column and are slidably connected to the sliding plate to increase the stability and balance of the crane. However, since the slide rails are directly exposed to the air, dust and debris in the air may adhere to the surface of the slide rails, which may cause the sliding plate to move smoothly on the slide rails, affecting the working efficiency of the crane and requiring frequent cleaning by the staff, which is rather inconvenient. Summary of the Utility Model

[0005] The purpose of this application is to provide a slide rail fixing structure to solve the problem that dust and debris in the air may adhere to the surface of the slide rails, which may cause the sliding plate to move smoothly on the slide rails.

[0006] To achieve the above purpose, this application specifically adopts the following technical solutions:

[0007] A slide rail fixing structure includes a fixing block. One side of the fixing block is fixedly connected with a lifting plate. The two sides of the lifting plate are slidably provided with support plates. One side of the support plate close to the lifting plate is fixedly connected with a slide rail. One side of the fixing block close to the support plate is rotatably connected with a rotating rod. The end of the rotating rod far from the fixing block is fixedly connected with a limiting wheel. The limiting wheel is slidably connected with the slide rail. Cleaning mechanisms are arranged on the upper and lower sides of the fixing block, and a moving mechanism is arranged on one side of the lifting plate of the fixing block.

[0008] By adopting the above technical solution, the support plate is moved to a suitable position, then the lifting plate is moved down to above the workpiece, and then the workpiece is lifted. During the lifting and lowering process of the lifting plate, the lifting plate drives the fixed block to move, the fixed block drives the rotating rod to move, and the rotating rod drives the limiting wheel to move inside the sliding rail, thereby improving the stability and balance of the lifting plate during the lifting and lowering process. The cleaning structure can clean the inside of the sliding rail, thereby reducing the moving resistance during lifting and improving the efficiency of the crane. The position of the limiting wheel can be adjusted through the moving mechanism, so that the position of the limiting wheel can be flexibly adjusted according to the actual situation and requirements.

[0009] Further, the cleaning mechanism includes connecting rods on the upper and lower sides of the fixed connection block of the fixed connection plate. One end of the connecting rod away from the fixed block is fixedly connected with a connection plate. A cross plate is arranged on the side of the connection plate away from the connecting rod. A sponge pad is fixedly connected to one side of the cross plate, and the shape of the sponge pad is adapted to the shape of the sliding rail.

[0010] By adopting the above technical solution, the lifting plate drives the fixed block to move, the fixed block drives the connecting rod to move, the connecting rod drives the connection plate to move, and the movement of the connection plate will cause the cross plate to move, and the cross plate drives the sponge pad to move. Since the shape of the sponge pad is adapted to the shape of the sliding rail, the surface of the sliding rail is cleaned, thereby effectively removing dust, debris and other dirt attached to the sliding rail.

[0011] Further, two fastening bolts are arranged on one side of the connection plate in an equidistant sliding manner, and two threaded grooves are arranged on one side of the cross plate at equal intervals. The fastening bolts are threadedly connected with the threaded grooves.

[0012] By adopting the above technical solution, the sponge pad can be cleaned and replaced by connecting the connection plate and the cross plate through the fastening bolts.

[0013] Further, rotating seats are fixedly connected to both sides of the fixed block, and one side of the rotating seat away from the fixed block is rotatably connected with the connecting rod.

[0014] By adopting the above technical solution, the connecting rod is rotated on the top of the rotating seat, so that the position of the cross plate is moved to a position convenient for removal.

[0015] Further, a rotating plate is fixedly connected to the outside of the connecting rod at the top of the rotating seat. A sliding hole is opened on the outer surface of the rotating plate. A first threaded rod is fixedly connected to the outer surface of the connecting rod. The first threaded rod is slidably connected with the sliding hole, and a first nut is threadedly connected to the outer surface of the first threaded rod.

[0016] By adopting the above technical solution, the position of the first threaded rod is fixed by the first nut, so as to fix the connecting rod and improve the stability of the connecting rod during operation.

[0017] Further, the moving mechanism includes a moving plate fixedly connected to one side of a lifting plate on one side of the fixed block. A long hole one is formed inside the moving plate. One side of the fixed block is fixedly connected with a sliding plate, and the sliding plate is slidably connected with the long hole one.

[0018] By adopting the above technical solution, pulling the fixed block to move drives the sliding plate to move, so that the sliding plate moves inside the long hole one, and thus the position of the limiting wheel can be flexibly adjusted according to the actual situation and requirements.

[0019] Further, a vertical plate is fixedly connected to the top of the sliding plate. A long hole two is formed inside the moving plate above the long hole one. One side of the vertical plate is fixedly connected with a second threaded rod, and the second threaded rod is slidably connected with the long hole two. A second nut is threadedly connected to the outer surface of the second threaded rod.

[0020] By adopting the above technical solution, the position of the second threaded rod is fixed by the second nut, thereby fixing the position of the fixed block.

[0021] Further, a plugging rod is fixedly connected to one side of the fixed block. Two plugging slots are equidistantly arranged on both sides of the lifting plate, and the plugging rod is slidably connected with the plugging slots.

[0022] By adopting the above technical solution, the plugging rod and the plugging slots provide an additional support point for the fixed block, making the fixed block move more stably.

[0023] In summary, the present application includes at least one of the following beneficial effects;

[0024] 1. In the present application, when cleaning the slide rail, first, the lifting plate drives the sponge pad to move, so that the sponge pad cleans the surface of the slide rail, thereby effectively removing dust, debris and other dirt attached to the slide rail, reducing the frictional resistance during the movement of the sliding plate, improving the smoothness and efficiency of the lifting process, reducing energy consumption, and prolonging the service life of mechanical components.

[0025] 2. In the present application, when it is necessary to adjust the friction between the slide rail and the limiting wheel, the fixed block drives the sliding plate to move inside the long hole one, so that the position of the limiting wheel can be flexibly adjusted according to the actual situation and requirements, and the friction of the limiting wheel inside the slide rail can be optimally controlled, which helps to improve the efficiency and stability of the lifting plate, making the lifting plate perform better when hoisting and moving workpieces.

[0032] The following further describes this application in detail Figures 1-4 in conjunction with the attached drawings.

[0033] The embodiment of this application discloses a fixing structure for a slide rail.

[0034] Referring to Figure 1 and Figure 2 , a fixing structure for a slide rail includes a fixed block 1. One side of the fixed block 1 is fixedly connected with a lifting plate 2. Support plates 5 are slidably arranged on both sides of the lifting plate 2. A slide rail 6 is fixedly connected to the surface of the support plate 5 close to the lifting plate 2. One side of the fixed block 1 close to the support plate 5 is rotatably connected with a rotating rod 3. The end of the rotating rod 3 far from the fixed block 1 is fixedly connected with a limiting wheel 4. The limiting wheel 4 is slidably connected with the slide rail 6. Cleaning mechanisms are arranged on the upper and lower sides of the fixed block 1. A moving mechanism is arranged on the surface of the lifting plate 2 on one side of the fixed block 1.

[0035] When lifting a workpiece, first move the support plate 5 to a suitable position, then move the lifting plate 2 down to the upper side of the workpiece, and then lift the workpiece. During the lifting and lowering process of the lifting plate 2, the lifting plate 2 drives the fixed block 1 to move, the fixed block 1 drives the rotating rod 3 to move, and the rotating rod 3 drives the limiting wheel 4 to move inside the slide rail 6, thereby improving the stability and balance of the lifting plate 2 during the lifting and lowering process. When the fixed block 1 moves, the cleaning structure can clean the surface of the slide rail 6, thereby reducing the moving resistance during the lifting process and improving the efficiency of the crane. The position of the limiting wheel 4 can be adjusted through the moving mechanism, so that the position of the limiting wheel 4 can be flexibly adjusted according to the actual situation and requirements.

[0036] Referring to Figures 1 to 3, the cleaning mechanism includes connecting rods 22 on the upper and lower sides of the fixed connecting plate 23 of the fixed block 1. One end of the connecting rod 22 away from the fixed block 1 is fixedly connected to a connecting plate 23. A cross plate 7 is arranged on the side of the connecting plate 23 away from the connecting rod 22. A sponge pad 8 is fixedly connected to one side of the cross plate 7. The shape of the sponge pad 8 is adapted to the shape of the slide rail 6.

[0037] Among them, two fastening bolts 9 are arranged on one side of the connecting plate 23 in an equidistant sliding manner. Two threaded grooves are arranged on one side of the cross plate 7 at equal intervals. The fastening bolts 9 are threadedly connected to the threaded grooves.

[0038] In addition, rotating seats 10 are fixedly connected to both sides of the fixed block 1. The side of the rotating seat 10 away from the fixed block 1 is rotatably connected to the connecting rod 22.

[0039] And, a rotating plate 11 is fixedly connected to the outside of the connecting rod 22 at the top of the rotating seat 10. A sliding hole is arranged on the outer surface of the rotating plate 11. A first threaded rod 12 is fixedly connected to the outer surface of the connecting rod 22. The first threaded rod 12 is slidably connected to the sliding hole. A first nut 13 is threadedly connected to the outer surface of the first threaded rod 12.

[0040] When cleaning the slide rail 6, first, the lifting plate 2 drives the fixed block 1 to move. The movement of the fixed block 1 drives the connecting rod 22 to move. The movement of the connecting rod 22 drives the connecting plate 23 to move. And the movement of the connecting plate 23 will cause the cross plate 7 to move. The movement of the cross plate 7 drives the sponge pad 8 to move. Due to the shape of the sponge pad 8 being adapted to the shape of the slide rail 6, the surface of the slide rail 6 is cleaned, effectively removing dust, debris, and other dirt attached to the slide rail 6, thereby reducing the frictional resistance during the movement of the slide plate 16, improving the smoothness and efficiency of the lifting process, reducing energy consumption, and prolonging the service life of mechanical components. After long-term use, the cross plate 7 can be removed by connecting the connecting plate 23 and the cross plate 7 through the fastening bolts 9, so as to clean and replace the sponge pad 8 for the next use. When removing the sponge pad 8, the connecting rod 22 can be rotated on the top of the rotating seat 10 to move the position of the cross plate 7 to a position convenient for removal, achieving the purpose of facilitating regular cleaning and replacement of the sponge pad 8, and reducing the corrosion and wear of dirt on the slide rail 6 and other mechanical components. When the sponge pad 8 is replaced or cleaned, the sponge pad 8 is reset. The connecting rod 22 will drive the first threaded rod 12 to rotate inside the sliding hole. When the sponge pad 8 is located inside the slide rail 6, the position of the first threaded rod 12 can be fixed through the first nut 13, thereby fixing the connecting rod 22 and improving the stability of the connecting rod 22 during operation.

[0041] Refer to Figure 3 and Figure 4The moving mechanism includes a moving plate 14 fixedly connected to one side of the fixed block 1 and one side of the lifting plate 2. A long hole 15 is opened inside the moving plate 14. A slide plate 16 is fixedly connected to one side of the fixed block 1. The slide plate 16 is slidably connected to the long hole 15. The outer surface of the threaded rod 19 is threadedly connected to a nut 20.

[0042] Among them, the top of the slide plate 16 is fixedly connected with a vertical plate 17, and a long hole 2 18 is opened inside the movable plate 14 above the long hole 15. A threaded rod 2 19 is fixedly connected to one side of the vertical plate 17, and the threaded rod 2 19 is slidably connected to the long hole 2 18.

[0043] In addition, a plug-in rod 21 is fixedly connected to one side of the fixed block 1, and two plug-in slots are equidistantly provided on both sides of the lifting plate 2, and the plug-in rod is slidably connected to the plug-in slots.

[0044] When the friction between the slide rail 6 and the limiting wheel 4 needs to be adjusted, the fixed block 1 is first pulled to move, and the movement of the fixed block 1 drives the slide plate 16 to move, so that the slide plate 16 moves inside the long hole 15, so that the position of the limiting wheel 4 can be flexibly adjusted according to actual conditions and needs, so that the friction inside the slide rail 6 is optimally controlled, which helps to improve the efficiency and stability of the lifting plate 2, so that the lifting plate 2 performs better when hoisting and moving workpieces. When the slide plate 16 slides, it will drive the vertical plate 17 to move, and the movement of the vertical plate 17 will drive the threaded rod 2 19 to slide inside the long hole 2 18. After sliding to a suitable position, the position of the threaded rod 2 19 is fixed by the nut 20, thereby fixing the position of the fixed block 1. By fixing the position of the fixed block 1, the fixed block 1 remains stable during operation, reducing unnecessary swinging and shaking. When the fixed block 1 moves, it is slidably connected with the plug-in slot through the plug-in rod 21. The plug-in rod 21 and the plug-in slot provide additional support points for the fixed block 1, making the fixed block 1 more stable when moving.

[0045] Working principle: move the supporting plate 5 to a suitable position, then move the lifting plate 2 down to the top of the workpiece, and then lift the workpiece. During the lifting and lowering process of the lifting plate 2, the lifting plate 2 drives the fixed block 1 to move, the movement of the fixed block 1 drives the rotating rod 3 to move, the movement of the rotating rod 3 drives the limiting wheel 4 to move inside the slide rail 6, thereby improving the stability and balance of the lifting plate 2 during the lifting process. The lifting plate 2 drives the fixed block 1 to move, the movement of the fixed block 1 drives the connecting rod 22 to move, the movement of the connecting rod 22 drives the connecting plate 23 to move, and the movement of the connecting plate 23 will cause the cross plate 7 to move, and the movement of the cross plate 7 drives the sponge pad 8 to move, and the sponge pad 8 is adapted to the shape of the slide rail 6, thereby cleaning the surface of the slide rail 6.

[0046] After long-term use, the cross plate 7 is connected to the connecting plate 23 through the fastening bolt 9, so that the cross plate 7 can be removed, and then the sponge pad 8 can be cleaned and replaced, which is convenient for the next use; pulling the fixed block 1 to move, the movement of the fixed block 1 drives the sliding plate 16 to move, so that the sliding plate 16 moves inside the long hole 15, so that the position of the limiting wheel 4 can be adjusted flexibly according to the actual situation and requirements, so as to optimize the control of the friction force of the limiting wheel 4 inside the slide rail 6.
