Problems solved by technology

Due to the large workload of hoisting the plate girder, the blockade time is long. If the existing bridge has multiple spans, the number of blockades will increase accordingly. Not only will the investment in manpower and material resources increase, but also the hidden dangers will increase, and at the same time, it will have a greater impact on railway transportation. , the construction has the problem that the blockade plan is difficult to approve

Embodiment Construction

[0012] Such as Figure 1-Figure 3 As shown, at the beam position that needs to be slid out, two tracks 1 are laid along the sliding direction, and short wooden sleepers 2 (spacing 0.5m) are set up under the track 1, and car stops 3 are set at both ends of the track 1 to prevent the car from slipping. Bottom steel frame 4 adorns two pairs of wheels 5 to cooperate with track 1. The supporting steel frame is divided into a vertical supporting steel frame 6, a horizontal supporting steel frame 7 and an oblique supporting steel frame 8. The four symmetrical vertical supporting steel frames 6 are connected with the bottom steel frame 4 through bolts, and the vertical supporting steel frame 6 and the horizontal support steel frame 7 are added with an oblique support steel frame 8 and fixed with bolts, and the upper and lower horizontal support steel frames 7 and the vertical support steel frames 6 are spliced ​​into a load-bearing frame. An oblique support steel frame 8 is added bet...

Abstract

The invention discloses a light combined type beam moving trolley. According to the main structure of the light combined type beam moving trolley, two pairs of wheels are mounted on a bottom steel frame to be matched with rails, four symmetrical vertical steel frames are connected with the bottom steel frame through bolts, oblique supporting steel frames are added between vertical supporting steel frames and transverse supporting steel frames and are fixed through bolts, the upper transverse supporting steel frame, the lower transverse supporting steel frame and the vertical supporting steel frames are spliced to form a bearing frame, sleepers are arranged on the transverse supporting steel frames, lifting jacks are arranged on the sleepers, a beam support is fixed to each pair of lifting jacks, a plate beam is jacked up and arranged on the trolley through the four lifting jacks, and the plate beam is moved out. According to the light combined type beam moving trolley, box iron, angle iron and the bolts are utilized for splicing the bearing frame, and the requirements of the maximum load of 10 t and a stable using structure can be met.

Description

technical field [0001] The invention relates to a trolley, in particular to a light-duty combined beam-moving trolley for sliding out an existing concrete slab girder in the reconstruction of an existing railway bridge. Background technique [0002] At present, the construction of dangerous bridge projects on existing domestic railway lines has been carried out in many places. Among the dangerous bridges, small bridges and culverts account for a considerable proportion, and the structures are mostly stone piers and concrete slab girders. Most of the design and construction schemes are to block the line and hang out the slab girder. Due to the large workload of hoisting the plate girder, the blockade time is long. If the existing bridge has multiple spans, the number of blockades will increase accordingly. Not only will the investment in manpower and material resources increase, but also the hidden dangers will increase, and at the same time, it will have a greater impact on ...
