Description

Technical Field

[0001] This utility model relates to the technical field of hoisting auxiliary devices, specifically a hoisting auxiliary device for large-volume prefabricated station components. Background Technology

[0002] Compared to ordinary prefabricated buildings, prefabricated subway stations involve the hoisting and installation of ultra-large components such as raft slabs. Furthermore, because subway construction is often carried out in urban areas with extremely limited site constraints, it is difficult to bring in large hoisting equipment such as crawler cranes. Therefore, how to lower large prefabricated components into the deep foundation pit of the station and install them becomes a common problem. Existing construction methods mainly involve using multiple hoisting devices such as cranes and gantry cranes to work simultaneously and collaboratively. However, because multiple hoisting devices are operated by individual operators, collisions between prefabricated components and other components during the lowering process can cause safety hazards such as tipping and swaying. Therefore, an auxiliary device for hoisting large-volume prefabricated station components is needed. Utility Model Content

[0003] The purpose of this utility model is to provide an auxiliary device for hoisting large-volume prefabricated station components, which solves the safety hazards such as tipping and swaying during the hoisting process of prefabricated components.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model is an auxiliary device for hoisting large-volume prefabricated station components, including a base, on which vertically distributed telescopic frames are installed on opposite sides;

[0006] At least two top plates are provided on the upper side of the two telescopic frames. The top plates are connected to the corresponding telescopic frames by columns. The height of the top plates can be changed by replacing columns of different lengths. The top plates are supported by the top plates.

[0007] Several support plates are provided above the two top plates, and the support plates are connected to the top plates by connectors;

[0008] The height of the top plate is changed by extending and retracting the telescopic frame in the vertical direction. A support plate is connected above the top plate to support the prefabricated components that are being hoisted and lowered.

[0009] When prefabricated components are fixed only by the hooks and steel cables of the hoisting device, they are prone to swaying during the descent, which makes it difficult to assemble the hoisted components with the prefabricated components to be installed.

[0010] By placing prefabricated components onto the pallet surface, and then retracting the pallet via a telescopic frame to descend synchronously with the prefabricated components, the movement of the prefabricated components is restricted, thus solving the problem of swaying during descent and hindering assembly.

[0011] Furthermore, the base includes a bottom rod and a crossbar, and there are two bottom rods and two crossbars. The bottom rods and crossbars are spaced apart and spliced ​​together to form a rectangular frame. A set of rollers is installed on the bottom surface of the bottom rod.

[0012] The base rod and the cross rod are perpendicular to each other and are connected by bolts. Individual rollers are installed on the bottom surface of the base rod by screws. The rollers facilitate the movement of the rectangular frame, and the entire structure can be moved by moving the rectangular frame, thereby adjusting the position of the hoisting auxiliary device.

[0013] Furthermore, the telescopic frame includes a first telescopic rod and a movable rod, the movable rod being located directly above the base rod, and a plurality of first telescopic rods being installed between the movable rod and the corresponding base rod.

[0014] Furthermore, the bottom end of the first telescopic rod is fixed to the upper surface of the base rod with bolts, and the top end of the first telescopic rod is installed on the lower surface of the movable rod with bolts. The movable rod is supported by the first telescopic rod. Several installed first telescopic rods rise and fall synchronously to change the height of the installed movable rod.

[0015] The connector includes a fixing component and a telescopic component. The fixing component includes a connecting rod and mounting seats connected to both ends of the connecting rod. The telescopic component includes a second telescopic rod and mounting seats connected to both ends of the second telescopic rod. The mounting seats are fixedly installed on the top plate or the support plate.

[0016] Furthermore, each of the opposite sides of the tray is provided with a connecting seat, and two adjacent trays are connected by a pin installed in the connecting seat.

[0017] A top block is installed on the upper surface of the pallet. The top block is made of rubber material and is installed on the upper surface of the pallet by screws. When the prefabricated part comes into contact with the pallet, the top block provides cushioning.

[0018] Furthermore, the middle support plate is connected to the top plate via a fastener, which supports the top plate. The two side support plates are connected to the top plate via telescopic components, and the tilt angle of the support plate is changed by altering the length of the telescopic components.

[0019] The plurality of pallets are distributed horizontally or along a curve to meet the bottom surface fit of different pre-components, thereby achieving support.

[0020] Furthermore, there are three trays. Since the middle tray is connected to the top plate through a fixing member, the position of the middle tray does not change. The trays on both sides are connected to the top plate through telescopic members. When the telescopic members shorten, the trays on both sides rotate downwards. When the telescopic members extend, the trays on both sides rotate upwards.

[0021] This utility model has the following beneficial effects:

[0022] This utility model uses a telescopic frame to extend and retract vertically, thereby changing the height of the top plate. A support plate is connected above the top plate to support the prefabricated components that are being hoisted and lowered. As the prefabricated components land on the support plate surface, the telescopic frame retracts and the support plate descends synchronously with the prefabricated components, thus limiting the movement of the prefabricated components and solving the problem of swaying during descent, which makes assembly inconvenient.

[0023] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-5 As shown, this utility model is an auxiliary device for hoisting large-volume prefabricated station components, including a base, with vertically distributed telescopic frames installed on both sides of the base.

[0034] At least two top plates 7 are provided on the upper side of the two telescopic frames. The top plates 7 are connected to the corresponding telescopic frames through columns 6. By replacing columns 6 of different lengths, the height of the top plates 7 can be changed. The top plates 7 are supported by the top plates 7.

[0035] Several support plates 11 are provided above the two top plates 7, and the support plates 11 are connected to the top plates 7 by connectors;

[0036] The height of the top plate 7 is changed by extending and retracting the telescopic frame in the vertical direction. A support plate 11 is connected above the top plate 7 to support the prefabricated components that fall during hoisting.

[0037] When prefabricated components are fixed only by the hooks and steel cables of the hoisting device, they are prone to swaying during the descent, which makes it difficult to assemble the hoisted components with the prefabricated components to be installed.

[0038] The prefabricated components are placed on the surface of the pallet 11, and the pallet 11 is lowered synchronously with the prefabricated components by the telescopic frame. This restricts the movement of the prefabricated components and solves the problem of shaking during descent, which makes assembly inconvenient.

[0039] The base includes a base rod 1 and a crossbar 2. There are two base rods 1 and two crossbars 2. The base rods 1 and crossbars 2 are spaced apart and spliced ​​together to form a rectangular frame. A set of rollers 3 are installed on the bottom surface of the base rod 1.

[0040] The base rod 1 and the cross rod 2 are perpendicular to each other and are connected by bolts. A single roller 3 is installed on the bottom surface of the base rod 1 by screws. The roller 3 facilitates the movement of the rectangular frame. The entire structure can be moved by moving the rectangular frame, thereby adjusting the position of the hoisting auxiliary device.

[0041] The telescopic frame includes a first telescopic rod 4 and a movable rod 5. The movable rod 5 is located directly above the base rod 1, and several first telescopic rods 4 are installed between the movable rod 5 and the corresponding base rod 1.

[0042] The bottom end of the first telescopic rod 4 is fixed to the upper surface of the base rod 1 by bolts, and the top end of the first telescopic rod 4 is installed on the lower surface of the movable rod 5 by bolts. The movable rod 5 is supported by the first telescopic rod 4. Several first telescopic rods 4 are installed and raised and lowered synchronously to change the height of the installed movable rod 5.

[0043] The connector includes a fixing component and a telescopic component. The fixing component includes a connecting rod 9 and mounting seats 8 connected to both ends of the connecting rod 9. The telescopic component includes a second telescopic rod 10 and mounting seats 8 connected to both ends of the second telescopic rod 10. The mounting seats 8 are fixedly installed on the top plate 7 or the support plate 11.

[0044] Each of the two opposite sides of the tray 11 is provided with a connecting seat, and two adjacent trays 11 are connected by a pin installed in the connecting seat.

[0045] A top block 12 is installed on the upper surface of the pallet 11. The top block 12 is made of rubber material and is installed on the upper surface of the pallet 11 by screws. When the prefabricated part comes into contact with the pallet 11, the top block 12 provides cushioning.

[0046] The middle support plate 11 is connected to the top plate 7 by a fastener, which supports the top plate 7. The two side support plates 11 are connected to the top plate 7 by telescopic components, and the tilt angle of the support plate 11 can be changed by changing the length of the telescopic components.

[0047] Several support plates 11 are distributed horizontally or along a curve to meet the bottom surface fit of different pre-components, thereby achieving support.

[0048] like Figure 1 As shown, there are three trays 11. Since the middle tray 11 is connected to the top plate 7 through a fixing member, the position of the middle tray 11 does not change. The trays 11 on both sides are connected to the top plate 7 through telescopic members. When the telescopic members are shortened, the trays 11 on both sides rotate downward. When the telescopic members are extended, the trays 11 on both sides rotate upward.
