[0002] In bridge and construction projects, arch rib structures are key load-bearing and force-bearing components, and the quality of the connections between their segments is crucial to the safety and stability of the overall structure. Typically, arch ribs are made up of multiple steel structural units. To ensure the overall strength and stability of the structure, the arch rib units are usually connected by welding, and the welding between arch rib segments needs to be performed at high altitudes. To ensure welding quality and the safety of construction workers, work protection devices need to be installed at the arch rib connection points. However, since there are no extra holes on the arch ribs for fixing, welding is currently the most common fixing method for work protection devices, which can damage the flanges or top plates of the arch ribs, affecting the performance and appearance quality of the arch ribs. At the same time, it leads to cumbersome steps during installation and disassembly, especially at high altitudes and in limited construction spaces. This is time-consuming and labor-intensive, increases the difficulty of construction, and is not convenient for subsequent turnover. Therefore, an assembled arch rib welding work device is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0026] Example 1

[0027] like Figure 1-4 As shown, an assembled arch rib welding operation device includes two oppositely connected arch ribs 1, the top plate of the arch rib 1 is provided with flanges extending to both sides, and a manhole 2 is provided on the top plate, and a welding operation device 3 is installed on the flanges on both sides of the connection between the two arch ribs 1, which is used to protect the construction personnel on the top of the arch rib 1.

[0028] The welding operation device 3 includes two rows of symmetrically arranged columns 30, and the number of columns 30 in each row is multiple and equidistantly distributed. It should be noted that the number of columns 30 in each row is determined according to the length to be protected, and the spacing between the two rows of columns 30 should be adapted to the width of the top plate of the arch rib 1.

[0029] A placing cross bar 32 at the lower end is provided between two rows of corresponding columns 30, which is used to place the welding operation device 3 on the top plate of the arch rib 1. A plurality of connecting longitudinal bars 31 are provided between each row of columns 30. The connecting longitudinal bar 31 at the bottom is connected to all the placing cross bars 32, thereby forming a stable guardrail protection structure on both sides. A plurality of connecting cross bars 33 are also provided between the two outermost rows of columns 30, and are respectively connected to the remaining connecting longitudinal bars 31, thereby forming a guardrail protection structure at the end, while effectively enhancing the overall structural strength. The number of connecting longitudinal bars 31 and connecting cross bars 33 is determined according to the required protection height and is evenly distributed.

[0030] The bottom end of the column 30 is also provided with a locking member 304 that can be tightened from below the flange, and cooperates with the placement cross bar 32 to fix the welding operation device 3, so that the welding operation device 3 is fixed to the top of the arch rib 1 through the clamping relationship formed by the locking member 304 and the placement cross bar 32.

[0031] With such a design, when in use, the installation of the columns 30, the connecting longitudinal rods 31, the resting cross bars 32 and the connecting cross bars 33 can be completed on the ground, and then they are hoisted to the top plate of the arch rib 1 by hoisting equipment, and the resting cross bars 32 are placed on the top plate. Finally, the fixing effect is achieved by installing the locking parts 304, which effectively avoids damage to the arch ribs caused by welding, and is convenient for installation and turnover, providing safe and effective protection for the top plate circumferential seam welding operation between the segments of the arch rib 1 and for personnel entering the interior of the arch rib from the manhole 2 of the top plate of the arch rib 1.

[0032] In the preferred embodiment, the mounting cross bar 32, the connecting longitudinal bar 31 and the connecting cross bar 33 are all connected by cross fasteners. The cross fasteners are common commercial products on the market, so they will not be described in detail here. By using cross fasteners to connect, it is easy to achieve disassembly and assembly between them, and it is also easy to adjust the spacing between them.

[0033] Example 2

[0034] Further illustrate with reference to Example 1, Figure 5-9The structure shown, in order to further improve the convenience of fixing the locking piece 304 at high altitude, in this embodiment, the column 30 includes an outer rod 300 for connecting the shelf cross bar 32, the connecting longitudinal rod 31 and the connecting cross bar 33. The interior of the outer rod 300 is hollow, and both ends are open. The outer rod 300 is provided with a rotatable rotating sleeve rod 301, and both ends of the rotating sleeve rod 301 pass through the outer rod 300. A lifting groove 302 is provided on the passing section at the bottom of the rotating sleeve rod 301. The interior of the rotating sleeve rod 301 is hollow, and the top is open. A threaded wire is provided on the inner wall surface of the rotating sleeve rod 301. The internal thread of the rotating sleeve rod 301 is connected to a threaded lifting rod 303. The top of the threaded lifting rod 303 passes through the rotating sleeve rod 301 and is connected to a handle 305. The bottom end of the threaded lifting rod 303 is rotatably provided with a locking piece 304 passing through the lifting groove 302.

[0035] With this design, the protruding section at the top of the rotating sleeve rod 301 can be used to control it to rotate simultaneously with the threaded lifting rod 303 in the outer rod 300, thereby adjusting the direction of the locking piece 304. Before placing the welding work device 3, the direction of the locking piece 304 can be adjusted to the outside, so that the welding work device 3 will not be affected by the welding work device 3 when it is placed. However, after the welding work device 3 is placed, the locking piece 304 is rotated to the bottom of the flange by rotation, and the threaded lifting rod 303 in the rotating sleeve rod 301 is rotated separately by the handle 305 to control the locking piece 304 to rise in the lifting groove 302, thereby achieving clamping of the flange. When it needs to be removed, the above operation can be performed in reverse, so that construction personnel do not need to install it at the bottom of the column 30, and only need to operate above the column 30 to complete its fixation, which greatly reduces the difficulty of installation and improves construction safety.

[0036] In the preferred embodiment, a rotating groove 3000 is provided on the inner wall surface of the outer rod 300, and a rotating block 3010 that slides with the rotating groove 3000 is provided on the outside of the rotating sleeve rod 301. The rotating block 3010 rotates in the rotating groove 3000 to achieve a rotational connection between the two.

[0037] In the preferred embodiment, a T-shaped rotating hole 3030 is provided at the bottom end of the threaded lifting rod 303, and a T-shaped rotating block 3040 that rotates with the T-shaped rotating hole 3030 is provided at the top of one end of the locking member 304. Through the rotational cooperation between the T-shaped rotating hole 3030 and the T-shaped rotating block 3040, a rotational connection between the two can be achieved, while preventing separation.

[0038] In a preferred embodiment, the arc length of the rotating slot 3000 allows the rotating sleeve 301 to rotate ninety degrees, thereby limiting the rotating sleeve 301 to rotate ninety degrees, making it easier for the locking member 304 to switch between the two states.

[0039] Furthermore, temporary locking holes 3001 are provided on the side wall surfaces at both ends of the rotating groove 3000, and a telescopic damping component 306 that can be connected to any temporary locking hole 3001 is provided on the rotating block 3010. Through the cooperation between the telescopic damping component 306 and the two temporary locking holes 3001, the locking member 304 is temporarily restricted in two directions, thereby temporarily restricting the two states of the locking member 304, and at the same time it can also remind the construction personnel whether it has been rotated into place.

[0040] The telescopic damping component 306 includes a telescopic slot 3060 provided on the end surface of the rotating block 3010, and limit slots 3061 are provided on the opposite side walls of the telescopic slot 3060. A telescopic spring 3062 and a telescopic clamping block 3063 are provided in the telescopic slot 3060, and the front end of the telescopic clamping block 3063 can pass through the telescopic slot 3060 and be plugged into any temporary clamping hole 3001. The rear end of the telescopic clamping block 3063 is provided with a limit block 3064 that slidably cooperates with the limit slot 3061.

[0041] With such a design, the telescopic card block 3063 can be restricted by the limit block 3064 and the limit slot 3061 and under the action of the telescopic spring 3062, so as to achieve the effect of passing through the limit slot 3061. When the telescopic card block 3063 is rotated to the position of any temporary card hole 3001, it can pop out and plug into it, thereby achieving the effect of temporary restriction and prompt.

[0042] It should be noted that the front end of the telescopic block 3063 and the temporary card hole 3001 are both compatible spherical surfaces. Through the spherical design, only a certain rotational force needs to be applied to contact the connection between the two, so that the telescopic block 3063 shrinks under the extrusion of the contact surface, thereby releasing the temporary limit.

[0043] The above embodiments are merely preferred technical solutions of the present invention and should not be construed as limiting the present invention. The scope of protection of the present invention shall be the technical solutions set forth in the claims, including equivalent alternatives to the technical features of the technical solutions set forth in the claims. Equivalent alternatives and improvements within this scope are also within the scope of protection of the present invention.
