Problems solved by technology
[0004] In order to solve the above problems, the present invention provides a road and bridge crane that can be moved and fixed well and connected with various bolts, which can solve the problem that the movement is not convenient enough, and there is a problem that the movement problem is solved to cause the fixation to be unstable. Secondly, the connection method is too large. For a single problem, the combination of multiple connection methods is realized, and the movement is more convenient during the lifting and handling process, saving manpower and material resources

The invention relates to a road and bridge crane allowing excellent motion and fixation and having various bolt connection structures. The road and bridge crane includes a slide trough and a crane body. The slide trough is installed on one side of the bottom of the crane body. A supporting frame sleeves the external end of the slide trough. An electric hydraulic pushing rod is elastically connected to the lower end of the center of the supporting frame. Rotating wheels are rotatably connected to the bottom end of the supporting frame. A plurality of support connecting rods are fixedly connected to the upper end of the supporting frame. A rail is connected to one ends of the support connecting rods. A hoisting beam is fixedly connected to the upper ends of the support connecting rods. A rail bracket is fixedly connected to the lower end of the center of the hoisting beam. A slide block is slidingly connected to the lower end of the rail bracket and includes a movable wheel, a connection board, a fixed bottom board, and a movable connecting trough. The fixed bottom board is fixedly connected to the lower end of the slide block. The movable connecting trough is snapped onto the upper end of the fixed bottom board. The road and bridge crane has stability during hoisting of materials, so that work efficiency is improved; and meanwhile, the crane can hoist objects to all directions and positions in a construction field.
Description
technical field [0001] The invention relates to the technical field of road and bridge cranes, in particular to a road and bridge crane that can be moved and fixed well and connected with various bolts. Background technique [0002] Some working characteristics of lifting equipment are intermittent movements, that is, in a working cycle, the corresponding mechanisms for retrieving, moving, unloading and other actions work alternately. The development and use of cranes in the market are becoming more and more extensive. Due to There are often some accidents when lifting without outriggers and driving with hoisting, and the driving speed is faster than crawler cranes (crawler cranes); the operation is stable, the lifting capacity is large, and it can lift and walk within a specific range, but the road must be smooth and solid. The tire pressure meets the requirements, and the lifting distance from the ground shall not exceed 50CM; long-distance walking with a load is prohibite...
