Description

Technical Field

[0001] The utility model relates to the field of building installation and construction, in particular to a walking type installation bracket between adjacent bridge bodies. Background Art

[0002] The middle interval area of the bridge is an integral part of the bridge structure. It is located at the center of the bridge and is used to separate traffic flows in different directions. The middle interval area is usually composed of guardrails with a certain gap. The guardrails are made of rigid materials such as steel or concrete and have high strength and stability.

[0003] The setting of the middle interval area of the bridge can effectively prevent vehicles from crossing over each other and entering the opposite lane to cause collision. This protective function is particularly important for roads with high speeds such as highways. It can effectively reduce the possibility of traffic accidents and improve driving safety.

[0004] During bridge construction, electromechanical installation of components such as drainage pipes and pipeline supports must be carried out on the bridge body. Currently, installation work is usually carried out by building supports or using a vehicle-mounted lifting platform. Due to the relatively narrow space in the middle interval area of the bridge body, the disassembly and movement process of the above method is more troublesome, resulting in a more complicated installation process and low efficiency of the installation operation, which needs to be improved.

[0026] Example 1, see the attached Figure 1-24-5. A walking installation bracket between adjacent bridge bodies. The main body of the bracket is a square frame body 01 that can accommodate the installation personnel standing. Two cross braces 02 are symmetrically provided at both ends of the upper part of the square frame body. The cross braces are composed of two rod bodies 21 arranged side by side. There is a gap 22 between the two rod bodies 21. The length of the cross brace 02 is greater than the width of the square frame body 01, so that the cross brace can be supported between the bridge guardrails 51 on both sides. The square frame body 01 is located in the interval area between the bridge guardrails 51; support rollers 03 are provided at the outer ends of the cross brace 02. The support rollers 03 can provide rolling support for the square frame body 01, so that it can change its position by walking along the guardrail and perform installation work in sections. The support rollers 03 The upper end of the first wheel seat 31 is provided with a first bottom plate 32 that fits against the bottom surfaces of the two rod bodies 21. The middle part of the first bottom plate 32 is vertically provided with a first stud 33 extending from the gap 22 between the two rod bodies. The upper end of the first stud is sleeved with a first pressure plate 34, and a first nut 35 is installed on the first stud 33 above the first pressure plate. When the nut is screwed, the nut moves downward along the stud to press the first pressure plate 34. After the first pressure plate is pressed against the upper surface of the rod body 21, the nut no longer moves. If the nut is continued to be screwed, the nut will be supported by the first pressure plate and drive the stud upward through the thread, thereby pressing the first bottom plate 32 against the bottom surface of the rod body 21. The first pressure plate 34 and the first bottom plate 32 are clamped between the two rod bodies to lock the support roller 03.

[0027] A brake mechanism 36 is provided on the supporting roller 03, and after the bracket changes position while traveling, the roller is locked by the brake mechanism so that the bracket is in a fixed state.

[0028] The diameter of the stud is smaller than the gap 22 between the two rod bodies 21 and can slide freely in the gap 22 . This design is used to adjust the position of the supporting roller 03 on the cross brace 02 .

[0029] A vertical support rod 11 is provided between the upper frame and the lower frame of the square frame 01, and a horizontal support rod 12 is provided between the middle parts of the vertical support rods at both ends of the square frame 01. A limit rod 13 extending outward is provided at the connection between the horizontal support rod and the vertical support rod 11. A pad 131 is provided at the outer end of the limit rod. The pad 131 is close to the outer side surface of the bridge guardrail 51 and is used to provide limiting support for the square frame 01 in the middle to prevent it from shaking significantly and ensure the safety of the operation.

[0030] Two platform plates 14 are laid on the bottom surface of the square frame 01 . The platform plates cover the bottom surface of the square frame 01 . Relevant personnel stand on the platform plates 14 to perform installation work.

[0031] During the installation operation, the bracket is placed between the bridge guardrails 51, and the support rollers 03 at the ends of the cross braces 02 on both sides are supported on the upper surface of the bridge guardrails on both sides. The square frame 01 is hung in the interval area between the bridge guardrails 51, and the relevant personnel go down to the platform board 14 inside the square frame 01 to carry out the installation operation. After the installation of one pipeline bracket 52 is completed, the auxiliary personnel on the bridge push the bracket along the guardrail to the next one and carry out the installation operation in sections. This method simplifies the electromechanical installation process in the middle interval area of the bridge and can effectively improve the installation efficiency.

[0032] Example 2, see the attached Figure 3-4 6. This embodiment is based on the first embodiment, and a limiting roller 04 is provided at the connection portion of the cross brace 02 and the square frame 01. An annular limiting plate 41 is provided at the inner edge portion of the limiting roller 04. The limiting roller 04 is supported on the upper surface of the guardrail, and the annular limiting plate is supported on the inner side surface of the guardrail. A lateral limit is formed by the annular limiting plate 41, so that the limiting roller can provide a lateral limit for the bracket, thereby ensuring its straightness during walking and moving.

[0033] The second pressure plate 45 and the second bottom plate 43 are clamped between the two rod bodies 21 to lock the limiting roller 04. Through this design, the limiting roller 04 can also be adjusted on the cross brace 02, and the position can be adjusted according to the size characteristics of the bridge structure, and the flexibility of use is high.
