Description

Technical Field

[0001] This utility model relates to the field of lifting device structure technology, and in particular to a heavy lifting device structure for traffic facility isolation piers. Background Technology

[0002] In the process of modern transportation construction and maintenance, the handling and installation of traffic facility barriers are frequent and important. In order to improve work efficiency and safety, heavy lifting equipment has become a common tool for handling traffic facility barriers.

[0003] The clamping and releasing operations of existing lifting devices are relatively cumbersome. Most lifting devices use rigid fixing structures or require manual tightening to fix the traffic barriers. During the lifting operation, operators need to spend a lot of time and energy on installation and disassembly, which not only reduces work efficiency but also increases the labor intensity of operators. Moreover, this operation method poses certain safety hazards. If the tightening is not in place, the traffic barriers may loosen or slip during the lifting process, causing safety accidents. To solve the above problems, this application proposes a heavy-duty lifting device structure for traffic facility traffic barriers. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a heavy-duty lifting device structure for traffic facility isolation piers. This lifting device adopts a linkage structure design, utilizing a first rotating plate, a second rotating plate, a first clamping plate, and a second clamping plate to form a quadrilateral locking structure. When the crane lifts the isolation pier, this structure can automatically clamp and lock, and when released, it can automatically open, greatly simplifying the operation process. This not only significantly improves lifting efficiency but also reduces the labor intensity of operators.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A heavy-duty lifting device structure for traffic facility isolation piers includes a first rotating rod, a lifting block fixedly connected to the top of the first rotating rod, a lifting opening through the lifting block, first rotating plates rotatably connected to both ends of the first rotating rod, a second rotating rod rotatably connected to the two first rotating plates, two symmetrically arranged first clamping plates rotatably connected to the second rotating rod, a third rotating rod rotatably connected to the two second rotating plates, two symmetrically arranged second clamping plates rotatably connected to the third rotating rod, and a fourth rotating rod rotatably connected to the two first clamping plates and the two second clamping plates.

[0007] Preferably, the two first clamping plates and the second clamping plate are respectively fixedly connected to a fixing plate, and the fixing plate is arranged in a C-shape.

[0009] Preferably, a nameplate is fixedly connected to the front of the second clamping plate, and the nameplate is installed and fixed to the second clamping plate by multiple bolts.

[0010] Preferably, each of the first and second clamping plates is fixedly connected to a column at its bottom, each column is fitted with a hollow plate that is slidably connected to it on its outer wall, each hollow plate is provided with an adjustment mechanism, each hollow plate is fixedly connected to a connecting block at its bottom, and the two connecting blocks on the left and the two connecting blocks on the right are together fixedly connected to a fixing plate.

[0011] Preferably, the adjusting mechanism includes an anti-detachment block fixedly connected to the bottom of the column, the anti-detachment block being located inside the hollow plate and slidably connected thereto, a plurality of first through holes being provided through the column, a second through hole being provided through the hollow plate, and a locking member being installed on the hollow plate, the locking member being provided through the second through hole and one of the first through holes.

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

[0013] 1. This lifting device adopts a linkage structure design, utilizing a first rotating plate, a second rotating plate, a first clamping plate, and a second clamping plate to form a quadrilateral locking structure. When the crane lifts the isolation pier, this structure can automatically clamp and lock, eliminating the need for manual tightening; and it can automatically open when released, greatly simplifying the operation process. This not only significantly improves lifting efficiency and reduces the labor intensity of operators, but also avoids safety hazards caused by inadequate manual tightening, thus improving the safety of lifting operations.

[0014] 2. This lifting device is equipped with an adjustable fixed plate height adjustment mechanism. Through the cooperation of the column, hollow plate and locking parts, the staff can flexibly adjust the height of the fixed plate according to the different sizes of the isolation piers. This design allows the lifting device to be adapted to a variety of isolation piers, and the lifting work of isolation piers of different sizes can be completed without changing the lifting device. This reduces equipment procurement costs, shortens the preparation time for lifting work, and improves the overall construction progress.

[0015] In summary, this lifting device adopts a linkage structure design, utilizing a first rotating plate, a second rotating plate, a first clamping plate, and a second clamping plate to form a quadrilateral locking structure. When the crane lifts the isolation pier, this structure can automatically clamp and lock, and when it is released, it can automatically open, greatly simplifying the operation process. This not only significantly improves lifting efficiency but also reduces the labor intensity of operators. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1

[0023] Reference Figures 1-3A heavy-duty lifting device structure for traffic facility isolation piers includes a first rotating rod 1, a lifting block 2 fixedly connected to the top of the first rotating rod 1, a lifting port 3 extending through the lifting block 2 to allow for lifting with an external crane, first rotating plates 4 rotatably connected to both ends of the first rotating rod 1, and a second rotating rod 5 rotatably connected to both first rotating plates 4, with two symmetrically arranged first clamping plates 6 rotatably connected to the second rotating rod 5, the two first rotating plates 4 located outside the two first clamping plates 6, and second rotating plates 7 rotatably connected to both ends of the first rotating rod 1, the two first rotating plates 4 located outside the two second rotating plates 7, and a third rotating rod rotatably connected to both second rotating plates 7. 8. Two symmetrically arranged second clamping plates 9 are rotatably connected to the third rotating rod 8. The two second clamping plates 9 are located outside the two second rotating plates 7 and outside the two first clamping plates 6. A nameplate is fixedly connected to the front of the second clamping plate 9, displaying relevant information such as the production date and lifting load. The nameplate is installed and fixed to the second clamping plate 9 by multiple bolts. The two first clamping plates 6 and the second clamping plate 9 are rotatably connected to a fourth rotating rod 11. The two first clamping plates 6 and the second clamping plate 9 are respectively fixedly connected to a fixing plate 10. The fixing plate 10 is C-shaped. This lifting device uses a linkage structure, which can easily clamp and release, achieve lifting locking, and automatic release.

[0024] To further explain, when it is necessary to lift and move the traffic facility isolation pier, the lifting port 3 set on the lifting block 2 is connected to the hook of the crane. The first clamping plate 6 and the second clamping plate 9 are placed on both sides of the traffic facility isolation pier. The two fixing plates 10 are respectively inserted into the grooves on both sides of the traffic facility isolation pier. The traffic facility isolation pier is lifted by the crane. The quadrilateral formed by the first rotating plate 4, the second rotating plate 7, the first clamping plate 6, and the second clamping plate 9 can clamp and lock the lifted traffic facility isolation pier with a self-locking structure (when the isolation pier is lifted, gravity causes the first clamping plate 6 and the second clamping plate 9 to be squeezed inward, and the rotation constraint of the rotating rod forms a self-locking torque). After lifting, the isolation pier is clamped. After being released, it automatically opens, resulting in high lifting efficiency. Example 2

[0025] Reference Figures 4-5The difference between this embodiment and embodiment 1 is that in this embodiment, each first clamping plate 6 and second clamping plate 9 has a column 12 fixedly connected to its bottom. Each column 12 has a hollow plate 13 slidably connected to its outer wall. Each hollow plate 13 has an adjustment mechanism, which includes an anti-detachment block fixedly connected to the bottom of the column 12. The anti-detachment block is located inside the hollow plate 13 and slidably connected to it. The anti-detachment block is a square block. Multiple first through holes 15 are formed through the column 12, and second through holes 16 are formed through the hollow plate 13. A locking component 17 is installed on the 13. The locking component 17 consists of a bolt and a nut. The locking component 17 passes through the second through hole 16 and one of the first through holes 15. A connecting block 14 is fixedly connected to the bottom of each hollow plate 13. The two connecting blocks 14 on the left and the two connecting blocks 14 on the right are fixedly connected to the fixing plate 10. The second through hole 16 is matched with different first through holes 15 by the cooperation of the bolt, nut and locking component 17, so as to realize the height adjustment of the fixing plate 10. It can be used to hoist isolation piers of different sizes and has strong versatility.

[0026] To further explain, workers can remove the locking component 17 using external tools, allowing the hollow plate 13 to be moved up and down on the column 12, thereby adjusting the height of the fixing plate 10. The second through hole 16 can be matched with different first through holes 15, and the installation and fixing between the column 12 and the hollow plate 13 can be completed through the locking component 17.
