Description

Technical Field

[0001] The utility model belongs to the technical field of underground transportation, in particular to an underground pipeline transportation trolley. Background Art

[0002] The underground coal mine adopts the new technology of remote power supply and fluid supply. The pump station is set up in the auxiliary retreat tunnel to reduce the number of relocations in the future. The pump station lays the pipeline of the fluid supply system underground. As the working face advances, the pipeline is also recovered. In the case of pressure loss of remote fluid supply and the need to meet the normal pressure of the working face, the selection of pipeline material strength becomes particularly important. Under comprehensive factors, high-pressure thick-walled pipes are selected, but the disadvantage is that they are heavy;

[0003] The process of dismantling and recovering the pipeline becomes time-consuming and labor-intensive, which increases the labor intensity of employees. In the process of recovering the pipeline, the pipeline is transported by people carrying it. There is a risk of injury due to the unsynchronized movements when putting it on and taking it off the shoulder. Therefore, it is necessary to make a tool that can save time, labor and be safe in the process of recovering the pipeline. Therefore, an underground pipeline transporting trolley is proposed to address the above problems. Utility Model Content

[0004] In order to make up for the shortcomings of the existing technology, the utility model proposes an underground pipeline transporting trolley, which can more conveniently transport the pipeline, reduce safety hazards, and reduce the workload of operators.

[0007] A U-shaped resistance arm is fixed on one side of the support plate. The pipeline can be transported by inserting it into the U-shaped resistance arm, or the pipeline can be lifted above the support plate for transportation. An anti-slip pad is pasted on the top side of the support plate. Since the pipeline has a cylindrical structure and is easy to roll and fall, the stability of the pipeline placement can be ensured by providing an anti-slip pad.

[0008] Preferably, a connecting seat 1 is fixed to the top side of the vehicle body, and the connecting seat 1 is rotatably connected to a limit rod through a rotating shaft, and a guide slot hole is opened inside the limit rod, and a locking screw is fixed on the outer side of the middle part of the swing rod, and the locking screw is penetrated into the guide slot hole inside the limit rod, and a locking nut is rotatably assembled on the locking screw, and a locking rod is fixed on the outer side of the locking nut. When the swing rod is pressed down, the locking screw swings accordingly, and the locking screw slides along the guide slot hole in the limit rod at the same time. After the U-shaped resistance arm is lifted, the locking rod is pulled to drive the locking nut to rotate, so that the side of the limit rod and the swing rod can be clamped. Under the action of friction, the stability of the swing rod after being pressed down is guaranteed, and there is no need to continuously output the force to the swing rod, which can save more effort when transferring the pipeline.

[0009] Preferably, the three universal wheels on the bottom side of the vehicle body are arranged in a triangular position and designed as a three-wheel form. The front wheel controls the direction, and the two rear wheels play a stabilizing role. In addition, each wheel is a universal wheel, which greatly improves the flexibility during transportation.

[0010] Preferably, an installation slot is opened inside the vehicle body, and a lifting rod is rotatably installed in the installation slot through a pin shaft. A front shovel is fixed to the top of the lifting rod, which can facilitate the lifting operation of the pipeline and assist the transportation operation of the pipeline.

[0011] Preferably, the top of the lifting rod is fixedly connected to a fixing seat, a second connecting seat is fixed to the top side of the vehicle body, a cylinder is connected between the second connecting seat and the fixing seat, the top end of the cylinder is rotatably installed in the fixing seat, and the bottom end of the cylinder is rotatably installed in the second connecting seat.

[0012] Preferably, the handle at the top of the swing rod is provided with a cylinder switch acting on the cylinder, and the front shovel is arranged on one side of the U-shaped resistance arm.

[0013] The utility model is beneficial in that:

[0014] The utility model adopts the lever principle to set a trolley capable of transferring the pipeline. When the two trolleys cooperate in carrying, it can be applied to the narrow working surface underground. The use of the trolley completely eliminates the potential safety hazard, and turns the previously time-consuming, labor-intensive and dangerous work into a time-saving, labor-saving, safe and efficient one.

[0015] The use of a trolley reduces the labor intensity of employees. Normally, it takes three or four people to recycle a pipe once. Now, using a trolley, two people can complete the entire task, saving productivity, reducing labor intensity, and improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
