Description

Technical Field

[0001] The utility model relates to a movable hanging basket construction structure for installing mechanical and electrical pipe boxes in the median strip of a bridge, belonging to the technical field of highway bridges, and is applicable to the installation construction of mechanical and electrical pipe boxes under the condition of the median strip of a bridge. Background Art

[0002] With the development of modern bridge technology, cantilever continuous bridges spanning rivers, valleys, and roads are increasingly widely used. The key technology for the construction and installation of pipe boxes on bridge guardrails is the hanging basket. The hanging basket is installed on the already cast bridge concrete guardrail, and the construction and installation work of pipe box brackets and pipe boxes on the bridge guardrail are all carried out on the hanging basket. The construction or installation work inside the bridge concrete guardrail is very convenient, but the construction or installation work on its outside is not easy to carry out. In order to carry out the construction or installation work on the outside of the bridge guardrail, construction workers often need to operate on the outside of the bridge guardrail, which cannot guarantee the safety of construction workers.

[0003] Here, hanging baskets have gradually emerged on the market to help workers carry out construction or installation on the outside of the bridge guardrail, but the existing hanging baskets have the following deficiencies:

[0004] 1) When the working surface changes, it is necessary to manually move the hanging basket to the next working surface, which is cumbersome to operate, increases the wear of the hanging basket, and affects the service life of the hanging basket.

[0005] 2) When the working surface is limited, the existing aerial work equipment or hanging basket equipment on the market are all vehicle-mounted or large-scale electric equipment, which cannot meet the construction needs.

[0006] 3) The hanging basket of the existing technology is supported and fixed by counterweights or with the help of external forces. When the external force deviates in position or there is a problem with the counterweight, the hanging basket will relatively shift in position, and there is an easy risk of the hanging basket falling, and the safety performance of the hanging basket is relatively low.

[0007] For the research and development and construction of a movable hanging basket for installing mechanical and electrical pipe boxes in the median strip of a bridge, it is urgently necessary to propose a hanging basket that can improve construction efficiency while ensuring project quality and safety. Content of the Utility Model

[0008] The purpose of the utility model is to provide a movable hanging basket construction structure for installing mechanical and electrical pipe boxes in the median strip of a bridge, which is used to improve the efficiency of the research and development and construction of the movable hanging basket for installing mechanical and electrical pipe boxes in the median strip of a bridge, ensure construction safety, and ensure project quality and safety. To achieve the above purpose, the utility model adopts the following technical solutions: The movable hanging basket construction structure for installing mechanical and electrical pipe boxes in the median strip of a bridge includes:

[0009] The mobile trolley hanging basket placed on the bridge deck includes a mobile trolley and a hanging basket structure, which is composed of wheels, a trolley base, a counterweight box and a trolley frame; the hanging basket structure is composed of a trolley cantilever beam, a diagonal bracing angle steel, a channel steel vertical pole and a hanging basket;

[0010] The mobile hanging basket placed on the anti-collision guardrail includes a cantilever beam, rubber pulleys, pulley sleeves, brake pads, section steel vertical poles, hanging basket cross bars and a hanging basket base. One or more pulley sleeves are respectively arranged at the bottom of the left and right ends of the cantilever beam, and each pulley sleeve is installed with a rubber pulley and a brake pad. A plurality of section steel vertical poles are installed at the bottom of the middle section of the cantilever beam, and the left and right adjacent section steel vertical poles are connected and fixed through the hanging basket cross bars. A hanging basket base is arranged at the bottom of all the section steel vertical poles;

[0011] The temporary hanging device includes an angle steel support vertical pole, an angle steel support cross bar and an angle steel bracket;

[0012] The mechanical and electrical pipe box includes a silicon core pipe, a polyurethane mechanical and electrical pipe box and a pipe box cover;

[0013] The rapid concrete encapsulation system for the pipe box bridge crossing platform includes an outer formwork for the electrical pipe box, a concrete pipe and a fixing nut.

[0014] Further, anchor bolt holes are provided on the angle steel support vertical pole and welded to the angle steel support cross bar.

[0015] Further, the polyurethane mechanical and electrical pipe box is installed between two angle steel brackets, made through the angle steel brackets, the silicon core pipe is placed inside the polyurethane mechanical and electrical pipe box, and then the pipe box cover is installed on the top of the polyurethane mechanical and electrical pipe box.

[0016] Further, the outer formwork of the pipe box is arranged on the outer surface of the concrete pipe, and an installation groove for installing the concrete funnel-shaped inlet is provided on the outer formwork of the pipe box located on the upper surface of the concrete pipe. Through holes for fixing the concrete funnel-shaped inlet are provided on the installation groove, and corresponding threaded holes are provided on the concrete funnel-shaped inlet.

[0017] The beneficial effects of the utility model are:

[0018] 1) The mobile trolley hanging basket does not need to manually move the hanging basket to the next working surface, and can be driven by driving sources such as electric motors. The operation is simple, and the wear of the hanging basket can be effectively reduced and the service life of the hanging basket can be prolonged;

[0019] 2) The structure of the temporary hanging device is firm, which can avoid the fatigue failure of the welding points of the bracket due to the principle of mechanical vibration, and reduce the potential safety hazards of construction;

[0020] 3) Moreover, the temporary hanging device can play a role in temporarily hanging the mechanical and electrical pipe box, and the structural stress form is reasonable, with good technical and economic benefits;

[0021] 4) The rapid encapsulation system of the concrete for the pipe box crossover platform can rapidly encapsulate the mechanical and electrical pipe box of the crossover platform (since the length of the mechanical and electrical pipe box is very long, almost the same as the length of the bridge, so the mechanical and electrical pipe box will pass through the abutment. When passing through the abutment, the rapid encapsulation system of the concrete for the pipe box crossover platform can rapidly encapsulate it to play a fixing role), and the construction is convenient and efficient.
