Description

Technical Field

[0001] The utility model relates to a transport trolley, in particular to a transport trolley mechanism for a socket-and-spigot type cement pipeline. Background Art

[0002] During the road reconstruction construction process in old residential areas, it is necessary to repair and replace underground pipelines. Among the underground pipelines, rainwater and sewage pipes generally use cement socket-type pipes. Because the roads in old residential areas are too narrow, large cranes and excavators cannot enter the site to assist in construction after the trench is excavated. Cement socket-type pipes need to be replaced and installed by manpower. Cement socket-type pipes are heavy and easy to damage. The existing flatbed carts are not competent for the transportation and docking of pipes. How to develop a transportation and docking tool suitable for cement socket-type pipes has become a problem that needs to be solved in on-site construction. Summary of the invention

[0003] The utility model provides a trolley mechanism for transporting and docking a spigot-and-socket cement pipe, which realizes convenient transport and rapid docking of the spigot-and-socket cement pipe in a narrow ditch.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] A socket-and-spigot cement pipe transportation docking trolley mechanism comprises a flat trolley, a transported socket-and-spigot cement pipe and a socket-and-spigot cement pipe installed in place, the socket-and-spigot cement pipe installed in place is arranged on the bottom surface of a groove, a flat trolley is arranged on the bottom surface of the groove on the left side of the socket-and-spigot cement pipe installed in place, the transported socket-and-spigot cement pipe is arranged on the flat trolley, a pair of transverse channel steel rails are arranged parallel to each other on the body flat plate of the flat trolley, a slide rail bar is movably arranged in the transverse channel steel rail, and a top of the slide rail bar is provided with a plurality of slide rail bars. A socket-and-spigot cement pipe bracket is fixedly connected to the surface, in which the transported socket-and-spigot cement pipe lies horizontally, a bracket front limit rod insertion hole is provided on the vehicle body flat plate on the front side of the socket-and-spigot cement pipe bracket, a front limit rod is inserted into the bracket front limit rod insertion hole, a bracket rear limit rod insertion hole is provided on the vehicle body flat plate on the rear side of the socket-and-spigot cement pipe bracket, a rear limit rod is inserted into the bracket rear limit rod insertion hole; a single-sided push handle rod is connected to the left rear end of the vehicle body flat plate, and a traction rope connecting ring is provided at the right front end of the vehicle body flat plate.

[0006] A pair of triangular brackets are arranged on the lower bottom surface of the middle part of the vehicle body flat plate, the lower ends of the triangular brackets are connected to the wheel axle, and rubber solid wheels are arranged at both ends of the wheel axle.

[0007] The big end of the transported socket-and-spigot cement pipe is arranged at the left end of the vehicle body flat plate where the single-side push handle is located; a traction rope is connected to the traction rope connecting ring; the small end of the transported socket-and-spigot cement pipe transported to the position by the flat plate trolley is connected to the big end of the socket-and-spigot cement pipe installed in the position by socket-and-spigot connection.

[0008] The utility model is particularly suitable for transporting butt-jointed spigot-and-socket cement pipes in narrow grooves. A flatbed trolley with a single wheel pair occupies a relatively small space. Since the length of the spigot-and-socket cement pipe is greater than the length of the flatbed trolley, the problem of interference between the trolley push rod and the spigot-and-socket cement pipe is solved by providing a single-sided push handle. The movement of the trolley in the narrow groove is achieved by the cooperation of the traction rope on the front side of the vehicle body plate and the single-sided push handle. The butt-jointing of the two spigot-and-socket cement pipe bracket (7) on the vehicle body flat plate (4) is solved by the forward and backward movement of the spigot-and-socket cement pipe bracket (7) on the vehicle body flat plate (4), thereby improving the work efficiency of on-site construction.
