Description

Technical Field

[0001] This utility model belongs to the field of bridge splicing technology, specifically relating to a manned hoisting cage for welding highway beams. Background Technology

[0002] Some large-span highway beams are often prefabricated in sections due to their large size and heavy weight, and then assembled on site. Wet joints are formed by casting concrete between these prefabricated beams to join the cantilevered sections of the two beams together. Before this, the protruding steel bars on the cantilevered ends of the two prefabricated beams need to be welded together.

[0003] Currently, the traditional welding method involves workers standing under the joint of two precast beams in a suspended cage to weld the steel bars at the joint into one piece. However, most of the existing suspended cages are made by workers themselves by welding steel bars. The structure is simple and practical, but it has hidden safety hazards. In particular, as the usage time increases, the welding performance of this type of suspended cage will gradually weaken, and the overall load-bearing capacity will also decrease, posing a risk of falling.

[0004] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0005] The purpose of this invention is to overcome the problem that the manned cages used in the assembly of long-span highway beams in the prior art are mostly made by workers themselves by welding steel bars, which are practical but have hidden safety hazards. This invention provides a manned cage for welding highway beams.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A manned hoisting cage for welding highway beams includes: pipe columns, a carrier plate, an X-shaped channel plate, and a fall arresting net. At least four pipe columns are provided, distributed circumferentially, with guardrails between adjacent columns to enclose them. The carrier plate is horizontally positioned below and centered on the four pipe columns, with notches corresponding to the pipe columns at the included angles of the carrier plate. The lower end of each pipe column is inserted into a corresponding notch, and the lower end of the pipe column is flush with the lower surface of the carrier plate. The X-shaped channel plate is horizontally positioned on the lower surface of the carrier plate, with its slot extending to halfway down the lower end of the pipe column, thus partially blocking the lower end of the pipe column. The fall arresting net passes through both the pipe column cavity and the channel of the X-shaped channel plate, with its end protruding from the upper end of the pipe column to hook onto and tension the reinforcing steel bars on the end face of the precast beam.

[0008] In the aforementioned manned hoisting cage for welding highway beams, preferably, the upper end of the pipe column is provided with a lifting ring, the direction of the ring opening corresponding to the reinforcing steel bars on the end face of the precast beam.

[0009] Preferably, the length of the carrier plate corresponding to the ring opening direction of the lifting ring is not greater than the spacing between the reinforcing bars on the two precast beam end faces.

[0010] Preferably, the notch matches the dimensions of the end face of the tubing.

[0011] Preferably, the fall arresting rope net includes: horizontal ropes and vertical ropes, with multiple strands of the horizontal ropes interwoven to form a shape that conforms to the channel of the X-shaped groove plate;

[0012] The vertical rope has four strands, and the four strands are respectively located in the cavities of the four tubular columns.

[0013] Preferably, the lower end of the vertical rope is connected to the horizontal rope;

[0014] The upper end of the vertical rope protrudes from the upper end of the column it is located on, and the upper end of the vertical rope is provided with a hook.

[0015] Preferably, the hook size is larger than the diameter of the pipe opening.

[0016] Beneficial effects: This utility model has a simple structure, is easy to manufacture, has high overall strength, long service life, and can ensure the personal safety of workers during use. That is, through the built-in anti-fall structure, it ensures that the cage will not have safety accidents, and the use effect is excellent. Attached Figure Description

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0027] This embodiment aims to provide a manned hoist cage for welding highway beams, whose main function is to ensure the personal safety of workers during use.

[0028] Reference Figures 1 to 5The system includes: four pipe columns 1, a carrier plate 3, an X-shaped channel plate 5, and a fall arresting rope net 6. Four pipe columns 1 are provided, each a rectangular steel pipe. These four pipe columns 1 are distributed circumferentially to form a rectangular space. Guardrails 2 are installed between adjacent pipe columns 1, securing the four pipe columns 1 together. A lifting ring 7 is welded to the upper end of each pipe column 1. The opening of the lifting ring 7 should correspond to the reinforcing steel bars on the end face of the precast beam, so that the ends of the reinforcing steel bars or steel pipes inserted into the lifting ring 7 can rest on the cantilever of the two precast beams respectively. The carrier plate 3 is horizontally positioned. Below and in the center of the four pipe columns 1, there are notches 4 at the four corners of the carrier plate 3. The four notches 4 correspond to the four pipe columns 1, and the dimensions of the notches 4 and the end face of the pipe columns 1 are matched so that the lower end of the pipe column 1 can be inserted into the corresponding notch 4 for welding, and ensure that the lower end of the pipe column 1 is flush with the lower plate surface of the carrier plate 3 so as to install the X-shaped groove plate 5. The length dimension of the carrier plate 3 in the direction of the ring 7 is not greater than the steel bar spacing of the two precast beam end faces. The purpose is to facilitate the workers to smoothly lower the device along the joint of the two precast beams.

[0029] Reference Figure 4 The X-shaped channel plate 5 is made of two channel steels welded together, and the weld joint of the two channel steels is opened. The X-shaped channel plate 5 is horizontally welded to the lower plate surface of the carrier plate 3 and centered, so that the X-shaped channel plate 5 provides a certain support for the carrier plate 3 and can enhance the load-bearing capacity of the carrier plate 3. The groove of the X-shaped channel plate 5 extends to half of the lower end of the pipe column 1, and the X-shaped channel plate 5 is welded to the lower end of the pipe column 1, so that the lower end of the pipe column 1 is in a semi-blocked state. This setting is to facilitate the steel wire rope of the fall arrest net 6 to enter the cavity of the pipe column 1 through the channel of the X-shaped channel plate 5.

[0030] Reference Figure 1 , Figure 3 and Figure 4 The fall arresting rope net 6 is made entirely of steel wire rope. It passes through both the cavity of the column 1 and the channel of the X-shaped channel plate 5. The end of the fall arresting rope net 6 protrudes from the top of the column 1 to hook onto the reinforcing steel on the end face of the precast beam and is tensioned. Specifically, the fall arresting rope net 6 includes horizontal ropes 8 and vertical ropes 9. Two horizontal ropes 8 are interwoven to form an X-shape that conforms to the channel of the X-shaped channel plate 5. The vertical ropes 9 have four strands, each located within the cavity of one of the four columns 1. The lower end of each vertical rope 9 is connected to the corresponding end of the horizontal rope 8, and the upper end of each vertical rope 9 protrudes from the top of the column 1. A hook 10 is provided at the upper end of each vertical rope 9, which is then hooked onto the reinforcing steel on the cantilever end face of the precast beam at a suitable distance to ensure the fall arresting rope net 6 is tensioned and to guarantee its protective effect.

[0031] In this embodiment, the hook 10 is larger than the diameter of the pipe opening of the column 1 to prevent the hook 10 from being accidentally pulled into the cavity of the column 1 by the wire rope and difficult to remove.

[0032] In actual use, steel bars or steel pipes are inserted horizontally into the two adjacent lifting rings 7 in the direction of the ring opening as suspension rods. It is best to make the two ends of the suspension rods the same length from the lifting rings 7. Then, the cage is lowered along the joint of the two precast beams by manual labor or lifting auxiliary equipment until the suspension rods are stably placed on the two precast beams. Then, the hooks 10 on the fall arrest net 6 are hooked onto the steel bars at appropriate distances, ensuring that the fall arrest net 6 is in a taut state. This allows the fall arrest net 6 and the cage to work together to play a load-bearing role and prevent falls.

[0033] The manned cage provided in this embodiment has a simple structure, is easy to manufacture, has high overall strength, a long service life, and can ensure the personal safety of workers during use. That is, through its built-in anti-fall structure, it ensures that the cage will not cause safety accidents, and its use effect is excellent.

[0034] It is understood that the above description is merely exemplary and the embodiments of this application do not limit the scope of the application.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
