Description

Technical Field

[0001] The present application relates to the technical field of hoisting devices, and in particular to a hoisting device for a rainwater square ditch. Background Art

[0002] A rainwater ditch is a drainage ditch whose specific function is to drain rainwater. During municipal construction, whether the rainwater ditch is constructed reasonably is related to whether the surrounding area can be well drained. Currently, rainwater ditches are mainly divided into open ditches and covered ditches. Open ditches have no cover or are equipped with water-permeable grates as covers. They are mainly used to drain surface water. Surface water can flow directly into the open ditch, collect, and be discharged. The lifting mechanism of the traditional rainwater ditch generally uses a crane or other device to connect the hook on the lifting mechanism, thereby providing lifting power for the lifting mechanism.

[0003] For example, a lifting mechanism for a rainwater square ditch disclosed in Chinese patent publication number (CN218909556U) belongs to the technical field of lifting mechanisms, and includes a fixed shell, a rotating groove is provided inside the fixed shell, a rotating rod is rotatably penetrated inside the fixed shell located at the lower side of the rotating groove, a handle is fixedly connected to the lower side of the rotating rod, and a first bevel gear is fixedly connected to the upper side of the rotating rod, and a second bevel gear is respectively engaged with the two sides of the first bevel gear, and a movable groove is provided inside the fixed shell located on both sides of the rotating groove; the rotating column is driven to rotate by rotating the handle, and the rotating column can drive the first bevel gear to rotate, and the first bevel gear can drive the second bevel gear to rotate when rotating, and the second bevel gear can drive the screw rod to rotate, and when the screw rod rotates, it can drive the movable plate to move, so that the movable plate drives the lifting mechanism to move, thereby facilitating the adjustment of the lifting mechanism, and further facilitating the lifting mechanism to clamp square ditches of different lengths.

[0004] However, the prior art, such as the above-mentioned patent, still has the problem of poor clamping and adjustment effect for square groove hoisting. For example, in the prior art, the square groove is clamped by a hoisting mechanism, and the clamping part of the clamping mechanism is a U-shaped clamping block, which is clamped by inserting the clamping block into the edge of the square groove. However, the internal size of the clamping block is fixed, which is not convenient for effective adjustment according to the thickness of the square groove. When facing a thicker square groove, it will cause it to be unable to be inserted, and when facing an overly thin square groove, it is easy to fall off due to the wider spacing. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the present application provides a lifting device for a rainwater square ditch, which has the advantages of easy lifting, adjustment and clamping, and solves the problem of poor clamping and adjustment effect for square ditch lifting in the existing technology.

[0014] Furthermore, buffer pads are fixed on the inner walls of the left and right sides of the adjustment cavity and on the outer sides of the extension plate, and a connecting hook is fixed on the upper surface of the lifting beam.

[0015] By adopting this technical solution, the use of buffer pads provides additional protection when the extension plate slides, reduces wear and tear, and extends the service life of the device. The setting of the connecting hook facilitates the connection of the lifting beam with other lifting equipment and simplifies the lifting process.

[0016] Furthermore, an adjustment opening is provided on the outer side of the clamping arm, and the clamping plate is slidably connected between the front and rear inner walls of the adjustment opening.

[0017] By adopting this technical solution, the clamping plate is connected through the sliding of the adjustment port, and the clamping width can be easily adjusted to adapt to square grooves of different widths.

[0018] Furthermore, guide rails are fixed to the front and rear inner walls of the adjustment port, and sliding grooves are provided on the front and rear sides of the clamping plate, and the clamping plate is slidably connected to the outer side of the guide rails through the sliding grooves.

[0019] By adopting this technical solution, the design of the guide rail and the slide groove ensures that the sliding of the clamping plate is smoother and more precise, thereby improving the stability and reliability of the clamping.

[0020] Furthermore, anti-drop caps are mounted on both the front and rear ends of the rotating shaft.

[0021] By adopting this technical solution, the anti-drop caps at both ends of the rotating shaft can prevent the rotating shaft from accidentally falling off during use, thereby improving the safety and durability of the device.

[0022] Furthermore, the width of the load-bearing plate is equal to the width of the clamping arm, and the width of the clamping plate is equal to the width of the load-bearing plate.

[0023] By adopting this technical solution, the consistency of the width of the load-bearing plate and the clamping plate ensures that the square ditch is evenly stressed during the lifting process, preventing damage caused by uneven stress.

[0024] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

The extension mechanism and the lifting mechanism jointly improve the efficiency, safety and adaptability of the rainwater square ditch lifting.

[0026] 2.

[0032] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] See also Figure 1 In this embodiment, a lifting device for a rainwater square ditch includes a lifting beam 1, an extension mechanism 2 is provided inside the lifting beam 1, and a lifting mechanism 3 is provided on the opposite side of the extension mechanism 2.

[0034] See also Figures 2 to 3In order to facilitate the adjustment of lifting according to the length of the square groove, the extension mechanism 2 in this embodiment includes two first hydraulic cylinders 21, two extension plates 22 and two fixed blocks 23. An adjustment chamber 24 is opened inside the lifting beam 1. The two first hydraulic cylinders 21 are arranged in parallel and are both fixed to the inner bottom wall of the adjustment chamber 24. According to the length of the square groove, the extension mechanism 2 is operated, and the first hydraulic cylinder 21 pushes the extension plate 22 to extend outward along the sliding opening 25 to adapt to square grooves of different lengths. Sliding openings 25 are opened on the left and right inner walls of the adjusting chamber 24, and the extension plates 22 are respectively slidably connected along the inner walls of the two sliding openings 25. The opposite sides of the two extension plates 22 are respectively fixed to the outer sides of the output shafts of the two first hydraulic cylinders 21, and the two fixed blocks 23 are respectively fixed to the opposite sides of the two extension plates 22. After the extension plates 22 are adjusted to the appropriate position, ensure that they are fixed in place, check whether the extension mechanism 2 is stable, and prepare to clamp with the edge of the square groove.

[0035] In this embodiment, storage grooves are provided on the left and right sides of the lifting beam 1, and the length of the inner side wall of the storage groove is equal to the width of the fixed block 23. The outer sides of the two extension plates 22 are fixed with limit plates 26. In the process of extending the extension plates 22, the internal limit plates 26 play the role of end limit to prevent the extension plates 22 from extending too much, thereby avoiding affecting the lifting use, and the height of the limit plates 26 is greater than the distance between the upper and lower inner walls of the sliding opening 25. Buffer pads are fixed on the left and right inner walls of the adjustment cavity 24 and on the outer sides of the extension plates 22. The buffer pads are arranged on the inner walls on both sides of the adjustment cavity 24 to provide effective protection for the contact between the limit plates 26 and the cavity walls, reducing impact and wear. A connecting hook 4 is fixed on the upper surface of the lifting beam 1.

[0036] See also Figure 4In order to facilitate the adjustment and clamping of the square groove, the lifting mechanism 3 in this embodiment includes two rotating columns 31 and two steel ropes 32. The two rotating columns 31 are rotatably connected to the lower surfaces of the two fixed blocks 23 respectively. The extension mechanism 2 is adjusted according to the length of the square groove and connected to the lifting equipment through the connecting hook 4. The lifting beam 1 is moved to the appropriate position above the square groove to ensure that it can correctly cover the square groove and prepare for lifting. The outer sides of the two rotating columns 31 are provided with connecting holes, and the two steel ropes 32 are respectively fixed to the inner walls of the two connecting holes. The two ends of the steel ropes 32 are respectively fixed with clamping arm rods 33, and the middle parts of the two clamping arms 33 are provided with The rotating hole has a rotating shaft 34 inserted into the inner wall of the rotating hole. As the lifting equipment is raised, the gravity of the square ditch will cause the clamping arm 33 to rotate around the rotating shaft 34, reducing the arm spacing, increasing the clamping force, and ensuring that the square ditch will not fall off during the lifting process. The bottom of the two clamping arms 33 on the opposite side is fixed with a load-bearing plate 35, and the load-bearing plate 35 is placed on the lower side of the edge of the square ditch to provide support for lifting. The two clamping arms 33 are fixed on the opposite side of each other. The outer side of the output shaft of the two second hydraulic cylinders 36 is fixed with a clamping plate 37. Start the second hydraulic cylinder 36 to extend its output shaft, pushing the clamping plate 37 to contact and fit with the upper side of the edge of the square ditch to achieve adjustable clamping.

[0037] In this embodiment, an adjustment port is provided on the outer side of the clamping arm 33, and the clamping plate 37 is slidably connected between the front and rear inner walls of the adjustment port. Guide rails 38 are fixed to the front and rear inner walls of the adjustment port. Slide grooves are provided on the front and rear sides of the clamping plate 37, and the clamping plate 37 is slidably connected to the outer side of the guide rail 38 through the slide grooves. Anti-slip caps are provided on the front and rear ends of the rotating shaft 34. The width of the load-bearing plate 35 is equal to the width of the clamping arm 33, and the width of the clamping plate 37 is equal to the width of the load-bearing plate 35. After confirming that the clamping is stable, operate the lifting equipment to lift the lifting beam 1, lift the square ditch and move it to the designated position. After the square ditch reaches the designated position, slowly lower it to the ground to ensure safe placement, and then operate the lifting mechanism 3 to release the square ditch.

[0038] The working principle of the above embodiment is:

[0039] (1) According to the length of the square groove, operate the extension mechanism 2, and push the extension plate 22 outward along the sliding opening 25 through the first hydraulic cylinder 21 to adapt to square grooves of different lengths. During the extension of the extension plate 22, the internal limit plate 26 plays the role of the end limit to prevent the extension plate 22 from being excessively extended, thereby avoiding affecting the use of lifting. Buffer pads are set on the inner walls of the adjustment cavity 24 on both sides to provide effective protection for the contact between the limit plate 26 and the cavity wall, reducing impact and wear. After the extension plate 22 is adjusted to the appropriate position, ensure that they are fixed in place, and check whether the extension mechanism 2 is stable and prepare to clamp with the edge of the square groove.

[0040] (2) Adjust the extension mechanism 2 according to the length of the square ditch and connect it to the lifting equipment through the connecting hook 4. Move the lifting beam 1 to the appropriate position above the square ditch to ensure that it can properly cover the square ditch and prepare for lifting. Place the load-bearing plate 35 on the lower side of the edge of the square ditch to provide support for lifting. Start the second hydraulic cylinder 36 to extend its output shaft and push the clamping plate 37 to contact and fit with the upper side of the edge of the square ditch to achieve adjusted clamping. As the lifting equipment rises, the gravity of the square ditch will cause the clamping arm 33 to rotate around the rotating shaft 34, reducing the arm spacing and increasing the clamping force to ensure that the square ditch will not fall off during the lifting process. After confirming that the clamping is stable, operate the lifting equipment to raise the lifting beam 1, lift the square ditch and move it to the designated position. After the square ditch reaches the designated position, slowly lower it to the ground to ensure safe placement, and then operate the lifting mechanism 3 to release the square ditch.
