Description

Technical Field

[0001] This utility model relates to the field of bridge construction, specifically to a mobile operating platform capable of simultaneous multi-point construction. Background Technology

[0002] Large steel truss bridges often employ piecemeal installation on-site, making it impossible to pre-deploy construction operation platforms. These platforms typically need to be set up on-site at the joints between structural members to meet construction needs. On one hand, steel truss bridges have a wide variety and large quantity of structural members, numerous connection points, and many construction sites, requiring a large number of construction operation platforms. On the other hand, existing bridge inspection vehicle tracks are usually pre-installed on the bridge deck and installed along with it. However, due to the bridge deck structure and the arrangement of the track connectors, the tracks often extend 2-3 meters beyond the front of the bridge deck to connect with the next deck. This necessitates the erection of a dedicated construction operation platform at the connection point between the track and the next deck after the previous deck is installed, making it impossible to utilize existing platforms. These two factors result in the need to erect numerous platforms during bridge construction, which require continuous installation and dismantling as the bridge installation progresses, leading to a large workload, low efficiency, and significant safety risks. Utility Model Content

[0003] Purpose of the utility model: The purpose of this utility model is to provide a mobile operating platform that can simultaneously carry out construction at multiple locations, solving the problems of existing technologies that require setting up operating platforms at multiple locations, continuous installation and dismantling, and safety risks.

[0004] Technical Solution: This utility model discloses a mobile operating platform capable of simultaneous multi-point construction. It is a frame structure comprising a transverse truss and a U-shaped frame. Vertical trusses are arranged on both sides of the transverse truss. The U-shaped frame surrounds the cross-section of the transverse truss and serves as the lifting point for the mobile operating platform, connecting to the walking system. The walking system is adapted to the walking track under the steel beam, providing power for the mobile operating platform to move along the track. A cantilever structure is detachably connected to the front of the transverse truss. A platform is mounted on the truss, with its height matching the corresponding construction point on site.

[0005] Furthermore, the cantilever structure is connected to the transverse truss by a pin, and a steel wire rope is installed on each side of the cantilever structure to prevent the cantilever structure from swaying.

[0006] Furthermore, the cantilever structure extends 2-3m.

[0007] Furthermore, the platform is multi-layered, with ladders connecting different layers.

[0008] Furthermore, a stop block is installed on the travel track to stop and prevent the mobile operating platform from sliding off the track.

[0009] Furthermore, the transverse trusses are welded together with the vertical trusses.

[0010] Furthermore, the U-shaped frame is welded to the transverse truss.

[0011] Beneficial Effects: Compared with existing technologies, this utility model has the following advantages: The walking system allows for forward and backward movement of the operating platform; the cantilever structure allows personnel to access the front end via the rear platform, thus connecting the next bridge deck to the track; and the vertical truss, horizontal truss, and platforms on the trusses enable simultaneous multi-point construction. This utility model is used for construction at the lower interface of steel truss bridges, eliminating the need for repeated installation and disassembly, reducing workload, improving construction efficiency, saving construction costs, and lowering construction safety risks.

[0019] like Figures 1 to 4 As shown, this utility model embodiment provides a mobile operating platform that can simultaneously carry out multi-point construction. It is a frame structure, including a horizontal truss 4 and a U-shaped frame 6. Vertical trusses 5 are welded to both sides of the horizontal truss 4. Three-layer platform 1 is set on the truss. The height of the platform matches the corresponding construction point on site. Different construction personnel can carry out construction simultaneously by standing on the corresponding platform. Ladders 8 are set between different layers for construction personnel to move up and down from the bridge deck to the operating platform.

[0020] The U-shaped frame 6 surrounds the cross-section of the transverse truss 4 and is welded to the transverse truss 4 to strengthen it. Simultaneously, the U-shaped frame 6 also serves as a lifting point for the mobile operating platform, connecting to the walking system 7. In this embodiment, there is one U-shaped frame 6 on each side.

[0021] The walking system 7 is adapted to the walking track under the steel beam, providing power for the mobile operating platform to move along the walking track. This walking system 7 is existing technology and will not be described in detail here. A stop block 3 with a U-shaped structure is fixed on the walking track to stop the mobile operating platform and prevent it from sliding off the track.

[0022] The front of the transverse truss 4 is connected to a cantilever structure 2 via a pin. This pin connection facilitates installation and removal as needed during construction. A steel wire rope 9 is installed on each side of the cantilever structure 2 to prevent swaying. The cantilever structure 2 extends 2-3 meters. On-site construction personnel use the cantilever structure 2 to reach the connection point between the front track and the next bridge deck, connecting the track to the bridge deck to ensure the operating platform continues to move forward.
