Description

Technical Field

[0001] The utility model relates to a scaffolding trolley structure for transporting four-pile conductor racks, and in particular to a scaffolding trolley structure for transporting four-pile conductor racks used in the field of offshore unbinding. Background Art

[0002] When carrying out construction at sea, during the unbinding process at sea, construction workers will use scaffolding, which makes it easier for construction workers to climb up and perform unbinding operations.

[0003] After the four-pile jacket structure is firmly tied, it is shipped to the offshore construction site by sea. Due to the high center of gravity and heavy weight of the jacket structure, and the structural form, the sea tying point is set very high, more than 7m above the deck. The removal of the sea tying struts at the offshore site is affected by the height and sea conditions, which is very troublesome. According to the conventional method, fixed scaffolding is set at the four plugs at the bottom of the jacket. The erection workload is large and the cost is high. The fixed scaffolding will be damaged during the disassembly process and cannot be reused for a second time. Utility Model Content

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that the existing scaffolding for untying at sea will be damaged during the disassembly process and cannot be reused for a second time.

[0005] In order to solve the above problems, the utility model provides a scaffold trolley structure for transporting four-pile conductor frames, including a scaffold, a walkway board overlapped on the surface of the scaffold, and installation grooves are opened at the four corners of the top of the walkway board. A fixing rod is fixedly connected to the inner wall of the installation groove, and a spring and a sleeved movable seat are sleeved on the surface of the fixing rod. A telescopic seat is fixedly connected to the top of the sleeved movable seat, and a connecting rod is fixedly connected to the surface of the walkway board at one side of the installation groove, and a supporting rod is fixedly connected to the surface of the connecting rod. A limiting ring is fixedly connected to the end of the support rod away from the connecting rod, and a sleeve block is sleeved on the surface of the limiting ring. A rotating extrusion block is fixedly connected to the bottom end of the walkway board, and a reinforcing movable block is fixedly connected to the bottom end of the walkway board. A reinforcing fixing groove matched with the reinforcing movable block is opened on the frame surface of the scaffold, and universal wheels are arranged at the four corners of the bottom of the scaffold.

[0006] In the above-mentioned scaffolding trolley structure for transporting four-pile conductor frames, it is not only easy to move and reuse, but also can ensure safety, and the stability of the walkway board thereon is relatively ideal and it is convenient for personnel to disassemble and assemble.

[0007] As a further improvement of the present application, one end of the telescopic seat away from the connecting rod is plugged into the frame of the scaffolding.

[0008] As a further improvement of the present application, a plug-in hole matched with the support rod is provided on the surface of the sleeve block, and a limiting hole matched with the limiting ring is provided inside the sleeve block.

[0009] As a further improvement of the present application, a through hole is provided on the surface of the sleeve movable seat, and the inner wall of the through hole is in contact with the surface of the fixing rod.

[0010] As a further improvement of the present application, the two ends of the spring are fixedly connected to the inner wall of the installation groove and the surface of the sleeve movable seat respectively, and the bottom surface of the sleeve movable seat is fitted with the inner bottom end of the installation groove.

[0011] As another improvement of the present application, a limiting plug-in slot is provided on the front side of the walkway plate, a limiting mounting plate is inserted inside the limiting plug-in slot, one end of the limiting mounting plate away from the walkway plate is fixedly connected to a material seat, the top of the material seat is fixedly connected to a material box, a limiting auxiliary slot is provided on the surface of the walkway plate located on one side of the mounting slot, a connecting reinforcement block is fixedly connected to the surface of the walkway plate located on one side of the limiting auxiliary slot, one end of the connecting reinforcement block is fixedly connected to an inner connecting rod, the surface of the inner connecting rod is fixedly connected to a connecting ring, the surface of the connecting ring is sleeved with an external tube, the surface of the external tube is fixedly connected to a flip frame, and a flip docking slot matching the flip frame is provided on the top of the limiting mounting plate.

[0012] As another improved supplement of the present application, the inner wall of the external tube is fitted with the surface of the internal connecting rod, and a connecting rotation groove matched with the connecting ring is opened on the inner wall of the external tube.

[0013] In summary, this structure is mainly used when untying at sea. When in use, it is only necessary to move the scaffolding to the position where it needs to be untied, and use the braking device of the universal wheel to fix it before construction can be carried out. Compared with the traditional detachable scaffolding, it can effectively shorten the construction time, improve construction efficiency, and save costs to the greatest extent. The two universal wheels on the rear side of the scaffolding have a braking function, which is convenient for the movement and reuse of the scaffolding, while ensuring safety. When installing the walkway board on the frame of the scaffolding, the walkway board needs to be overlapped on the frame of the scaffolding. After the walkway board is placed, the reinforced moving block will enter the reinforced fixing groove, thereby preventing the walkway board from moving left and right and forward and backward on the scaffolding. Then, the sleeve moving seat is pushed to squeeze the spring at one end, and drive the telescopic seat to move toward the scaffolding together. The frame can be inserted into the frame until one end of the telescopic seat is inserted into the frame, and then the sleeve block is rotated to drive the rotating extrusion block to rotate, so that one end of the rotating extrusion block is moved into the installation groove and fits with the inner wall of the installation groove. At the same time, the other end will be tightly against the sleeve moving seat to prevent one end of the telescopic seat from moving out of the frame, thereby preventing the walkway board from moving upward, and then improving the stability of the walkway board, so as to prevent the walkway board from moving on the scaffolding due to inertia when the scaffolding is moved. Compared with the traditional installation method of directly overlapping the walkway board on the scaffolding and fixing the walkway board on the scaffolding with bolts, the structural installation method of the walkway board is not only convenient for personnel to operate and disassemble and assemble the walkway board, but also the stability of the walkway board after installation is more ideal.

[0026] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0027] The first implementation method:

[0028] Figure 1-3 and Figure 5-7 A scaffolding trolley structure for transporting a four-pile pipe frame is shown, comprising a scaffolding 1, a walkway board 2 is overlapped on the surface of the scaffolding 1, four corners of the top of the walkway board 2 are provided with mounting grooves 3, a fixing rod 4 is fixedly connected to the inner wall of the mounting groove 3, a spring 5 and a sleeved movable seat 6 are sleeved on the surface of the fixing rod 4, a telescopic seat 7 is fixedly connected to the top of the sleeved movable seat 6, a connecting rod 8 is fixedly connected to the surface of the walkway board 2 located on one side of the mounting groove 3, and a supporting rod is fixedly connected to the surface of the connecting rod 8 9, one end of the support rod 9 away from the connecting rod 8 is fixedly connected to the limit ring 10, the surface of the limit ring 10 is sleeved with a sleeve block 11, the bottom end of the sleeve block 11 is fixedly connected with a rotating extrusion block 12, the bottom end of the walkway board 2 is fixedly connected with a reinforcement moving block 25, the frame surface of the scaffolding 1 is provided with a reinforcement fixing groove 26 adapted to the reinforcement moving block 25, and universal wheels 27 are arranged at the four corners of the bottom of the scaffolding 1, and the end of the telescopic seat 7 away from the connecting rod 8 is plugged into the frame of the scaffolding 1;

[0029] This solution can be realized. The scaffold 1 is mainly used when untying at sea. When in use, the scaffold 1 only needs to be moved to the position where it needs to be untied, and the construction can be carried out by fixing it with the braking device of the universal wheel 27. Compared with the traditional detachable scaffold 1, it can effectively shorten the construction time, improve the construction efficiency, and save costs to the greatest extent. The two universal wheels 27 on the rear side of the scaffold 1 have a braking function, which is convenient for the scaffold 1 to be moved and reused, while ensuring safety;

[0030] When installing the walkway board 2 on the frame of the scaffolding 1, the walkway board 2 needs to be overlapped on the frame of the scaffolding 1. After the walkway board 2 is placed, the reinforcement moving block 25 will enter the reinforcement fixing groove 26, so as to prevent the walkway board 2 from moving left and right and forward and backward on the scaffolding 1. Then, the sleeve moving seat 6 is pushed to squeeze the spring 5 at one end, and the telescopic seat 7 is driven to move toward the frame of the scaffolding 1 until one end of the telescopic seat 7 is inserted into the frame. Then, the sleeve block 11 is rotated to drive the rotating extrusion block 12 to rotate, and one end of the rotating extrusion block 12 is moved into the installation groove 3 and aligned with the installation groove 3. The inner wall fits together, and at the same time, its other end will be tightly pressed against the sleeve movable seat 6 to prevent one end of the telescopic seat 7 from moving out of the frame, thereby preventing the walkway board 2 from moving upward, and then improving the stability of the walkway board 2, so as to prevent the walkway board 2 from moving on the scaffolding 1 due to inertia when the scaffolding 1 is moved. Compared with the traditional installation method of directly overlapping the walkway board 2 on the scaffolding 1 and fixing the walkway board 2 on the scaffolding 1 with bolts, the structure of installing the walkway board 2 is not only convenient for personnel to operate and disassemble and assemble the walkway board 2, but also the stability of the walkway board 2 after installation is more ideal.

[0031] Figure 8-9 It is shown that the surface of the sleeve block 11 is provided with a plug hole adapted to the support rod 9, the interior of the sleeve block 11 is provided with a limit hole adapted to the limit ring 10, the surface of the sleeve movable seat 6 is provided with a through hole, the inner wall of the through hole is fitted with the surface of the fixed rod 4, the two ends of the spring 5 are fixedly connected to the inner wall of the mounting groove 3 and the surface of the sleeve movable seat 6 respectively, and the bottom surface of the sleeve movable seat 6 is fitted with the inner bottom end of the mounting groove 3;

[0032] When in use, force is applied to the sleeve block 11 to make it rotate on the support rod 9. Since the diameter of the insertion hole is smaller than the diameter of the limit ring 10, the limit ring 10 can be prevented from moving out of the insertion hole, thereby preventing the sleeve block 11 from separating from the support rod 9.

[0033] The second implementation method:

[0034] Based on the first embodiment, this embodiment adds a material box 16 and other structures, and the rest of the parts are consistent with the first embodiment.

[0035] Figure 4-5 and Fig.10 It is shown that a limited insertion slot 13 is provided on the front of the walkway plate 2, and a limited mounting plate 14 is inserted inside the limited insertion slot 13. A material seat 15 is fixedly connected to the end of the limited mounting plate 14 away from the walkway plate 2, and a material box 16 is fixedly connected to the top of the material seat 15. A limited auxiliary slot 17 is provided on the surface of the walkway plate 2 located on one side of the mounting slot 3, and a connecting reinforcement block 18 is fixedly connected to the surface of the walkway plate 2 located on one side of the limited auxiliary slot 17. An inner connecting rod 19 is fixedly connected to one end of the connecting reinforcement block 18, and a connecting ring 20 is fixedly connected to the surface of the inner connecting rod 19. An external pipe 21 is sleeved on the surface of the connecting ring 20, and a flip frame 22 is fixedly connected to the surface of the external pipe 21. A flip docking slot 23 adapted to the flip frame 22 is provided on the top of the limited mounting plate 14, and the inner wall of the external pipe 21 is fitted with the surface of the inner connecting rod 19. A connecting rotation slot 24 adapted to the connecting ring 20 is provided on the inner wall of the external pipe 21.

[0036] This solution can be implemented. When in use, the limit mounting plate 14 needs to be inserted into the limit plug-in slot 13. After the limit mounting plate 14 is plugged in, the external tube 21 is rotated to make it rotate on the internal connecting rod 19. When the external tube 21 rotates, it will drive the flip frame 22 to rotate together until the end of the flip frame 22 away from the external tube 21 is inserted into the flip docking slot 23, thereby preventing the limit mounting plate 14 from moving out of the limit plug-in slot 13, and then installing the material seat 15 on the scaffold 1. During operation, the operator can place the operating tools and materials in the material box 16, thereby improving the convenience of the operator in taking and placing the operating tools and materials and facilitating the operator to place the tools and materials in a centralized manner.

[0037] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
