Technical Field

[0001] The utility model relates to the technical field of trolleys, in particular to a single hydraulic prop trolley. Background Technique

[0002] The single hydraulic prop, also called a single prop, is a single collapsible prop that uses liquid pressure to generate working resistance and realizes the functions of lifting the prop and unloading. It mainly consists of parts such as a cylinder body, a piston rod, and a valve, and is widely used in underground mining environments such as coal mines as a support device. The single hydraulic prop can be divided into two types: externally pressurized type and internally pressurized type according to the liquid supply method, into single-extension props and double-extension props according to different working strokes, and into steel props and light alloy props according to different materials used. It has the advantages of small volume, high support height, reliable support, convenient use and maintenance, and low comprehensive cost. It is a type of hydraulic support for fully mechanized mining equipment. In operations such as coal mines, it is often necessary to transport multiple groups of single props;

[0003] The transportation of single props requires the use of a trolley. In the prior art, generally, a simple frame is welded to form a vehicle body, and rollers are connected to the lower end of the vehicle body as a whole trolley. During transportation, multiple groups of single props are placed on the top of the trolley, and the trolley is pushed for transportation. Since the single prop is generally cylindrical, it is easy to roll and slide on the top of the trolley. And if a limiting baffle is fixed on the top of the trolley, it is not convenient for rolling and discharging. Therefore, the utility model proposes a single prop trolley to solve the problems existing in the prior art. Summary of the Invention

[0004] In view of the above problems, the utility model proposes a single prop trolley. The single prop trolley limits the single prop from both sides through the insertion pipes on both sides to prevent sliding. Inserting different numbers of insertion rods can also adapt to single props of different lengths. During unloading, only the insertion rods need to be pulled out, and rolling unloading can be achieved in cooperation with the guiding component, which is more convenient.

[0005] To achieve the purpose of the utility model, the utility model is realized through the following technical solutions: A single prop trolley includes a vehicle frame and support feet. The inside of the vehicle frame is hollow, and support feet are provided at the four corners of the bottom of the vehicle frame. A walking component is provided at the bottom of the support feet.

On both sides of the top of the vehicle frame, there are insertion pipes, and multiple groups of insertion pipes are equidistantly arranged on both sides. An insertion rod is inserted inside the insertion pipe, and a magnetic attraction block is provided at the bottom inside the insertion pipe. The lower end of the insertion rod is magnetically attracted to the magnetic attraction block;

[0006] A guiding component is movably arranged inside the vehicle frame, and a through groove is provided at the front side of the vehicle frame. The guiding component passes through the through groove.

[0007] The further improvement lies in that: the guiding component includes a sliding rod, a connecting arm and a guiding arm. Both ends inside the vehicle frame are provided with sliding grooves. The two ends of the sliding rod are respectively movably connected to the sliding grooves at both ends. The connecting arm is connected to the sliding rod, and a hinge is provided on the front side of the connecting arm. The guiding arm is rotatably connected to the connecting arm through the hinge.

[0008] The further improvement lies in that: multiple groups of the connecting arms and the guiding arms are equidistantly arranged, and the front side of the guiding arm extends out of the through groove.

[0009] The further improvement lies in that: on the front side of the vehicle frame at the position above the through groove, multiple groups of guiding blocks are equidistantly arranged, and the top surface of the guiding block is inclined downward.

[0010] The further improvement lies in that: at both ends of the rear side inside the vehicle frame, clamping sleeves are provided, and the clamping sleeves are adapted to the sliding rod.

[0011] The further improvement lies in that: the traveling component includes a support plate and universal wheels. The support plate is connected to the lower end of the support leg, the universal wheels are arranged at the lower end of the support plate, and a brake is provided on the universal wheels.

[0012] The further improvement lies in that: a reinforcing rod is connected between two adjacent groups of the support legs, and the reinforcing rod is integrally formed with the support legs.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. The present utility model uses the vehicle frame in cooperation with the bracket to support the single pillar for the single pillar to be placed. For single pillars of different lengths, the required insertion rods can be respectively inserted into the insertion tubes on both sides and fixed by magnetic attraction blocks. The insertion tubes on both sides limit the single pillar from both sides to prevent it from slipping. Inserting different numbers of insertion rods can also adapt to single pillars of different lengths. When unloading, only need to pull out the insertion rods and cooperate with the guiding component to roll and unload, which is more convenient.

[0015] 2. When unloading the present utility model, only need to pull out the guiding arm from the through groove, and the sliding rod moves along the sliding groove until the connecting arm extends out of the through groove. At this time, through the action of the hinge, the guiding arm can be rotated to support downward on the ground, and with the slope guiding of the guiding block, it is convenient to roll and unload the single pillar. Without manual handling, it is more labor-saving. Description of the Drawings
