Description

Technical Field

[0001] The utility model relates to the technical field of pipeline transport vehicles, in particular to a pipeline transport trolley. Background Art

[0002] With the rapid development of cities, the demand for the expansion and increase of municipal pipeline capacity has increased rapidly, so the construction of underground pipeline corridors has been rapidly launched. Among them, with the popularization of underground pipeline corridors, more and more projects are installing heat pipes or gas pipes in the pipeline corridors. Due to the long transportation distance and small operating space in the underground pipeline corridor, heat pipes or gas pipes are often transported in the pipeline corridor by small transport vehicles.

[0003] When installing large-diameter pipes in basements and garages, the construction ground has not yet been put into use, and vehicles cannot enter or exit. Pipes can only be transported by manpower or carts. Pipes are easy to roll off when transported by carts, which is extremely inconvenient. Manual transportation is labor-intensive and time-consuming. Therefore, a convenient pipeline transportation cart is proposed. Utility Model Content

[0006] Furthermore, a pull rod is rotatably provided on the side of one end of the fixing rod, and the pull rod facilitates the movement of the trolley and plays a guiding role.

[0007] Furthermore, wheels are rotatably provided at both ends of the main support rod.

[0008] Furthermore, the bottom end of the fixing rod is located on both sides of the supporting rod and a plurality of ear plates 1 are fixed thereto, the bottom end of the clamping plate is located on both sides of the supporting rod and a plurality of ear plates 2 are fixed thereto, the ear plates 1 correspond to the ear plates 2 and are divided into a plurality of groups, the bidirectional screw is rotatably connected to the ear plate 1 of the middle group and is threadedly connected to the ear plate 2 of the middle group, and there is a limiting rod slidably connected between the ear plates 1 and 2 of the remaining groups, and the rotation of the bidirectional screw drives the clamping plates on both sides to move along the limiting rod, thereby being able to clamp and fix pipes of different diameters.

[0009] Furthermore, a rotating handle is fixed to one end of the bidirectional screw.

[0010] Furthermore, a plurality of straps are connected between the two clamps, one end of the strap is fixedly connected to the upper end of one clamp, and the other end is clamped to the upper end of the other clamp via a snap mechanism, and the two ends of the strap are respectively connected to the two clamps. The strap can better fit the pipeline to enhance the fixing effect, and the strap has slight elasticity. When transporting pipelines of the same diameter, after adjusting the length of the strap for the first time, the snap mechanism can be used to directly plug in the pipeline during subsequent transportation, and the strap can tightly hold the pipeline.

[0011] Furthermore, the buckle mechanism includes a plurality of fixing blocks fixed on the upper end surface of one of the splints, and a slot is provided on the top surface of the fixing block, and a spring pin is provided on the outer side surface of the fixing block, one end of the strap is folded to form a folded portion, the folded portion passes through a connecting ring and is fixed by a fixing assembly, the connecting ring is inserted into the slot, and is fixed by the spring pin passing through the connecting ring.

[0012] Furthermore, the fixing assembly includes a rectangular tube sleeved on the binding strap and its folding portion, a fastening screw being threadedly arranged on a side surface of the rectangular tube, one end of the fastening screw passing through the side wall of the rectangular tube and being rotatably provided with a top plate, the top plate being capable of tightening the folding portion, and when transporting pipes of different diameters, the length of the binding strap can be adjusted by adjusting the fastening screw, thereby achieving a better fixing effect of the binding strap.

[0013] Furthermore, a plurality of fixing blocks 2 corresponding to the fixing block 1 are fixed on the upper end surface of the other clamping plate, a groove is provided on the top surface of the fixing block 2, a through hole is provided on the side surface of the groove and is equipped with bolts, a cylinder is fixed on the other end of the strap, the cylinder is inserted into the groove and fixed by passing the bolt through the cylinder, and one end of the strap is fixed by a bolt to facilitate replacement of the strap.

[0014] The beneficial effects of the technical solution provided by the embodiment of the utility model are: the device not only avoids manual handling when transporting the pipeline, saving time and effort, but also can fix pipelines of different diameters by using the clamping assembly, avoiding the problem that the pipeline is easy to roll off when transporting the pipeline by a trolley, which is both convenient and practical;

[0015] The device adjusts the distance between the two clamps through a bidirectional screw to adapt to the transportation of pipelines with different diameters. When transporting a pipeline with a smaller diameter, the clamp is used to clamp and fix the pipeline. When transporting a pipeline with a larger diameter, the clamp is used to clamp and limit the part of the pipeline close to the trolley, and then the pipeline is tightly tightened with a strap, so that pipelines of different diameters can be better fixed. After the length of the strap is set, the pipeline can be fixed by only plugging and unplugging the end with the buckle mechanism, which is convenient and quick to operate.

[0016] The device is also provided with an oblique pull rod to prevent personnel from bumping into each other when the trolley is towed. BRIEF DESCRIPTION OF THE DRAWINGS
