However, after the single hydraulic prop is repaired, a strict pressure test needs to be performed to ensure the safety and reliability of the single hydraulic prop. In a traditional pressure test device, a single prop is placed by manual carrying, and problems such as low efficiency and high labor intensity exist. Therefore, the hydraulic single prop testing frame is provided to solve the above problems. CONTENT OF THE UTILITY MODEL

In this process, the single column needs to be only slightly held without swinging, and the risk of hitting a worker is avoided, so that the operation is simple, the efficiency is high, and the labor intensity is small.

[0004] The hydraulic single prop testing frame is provided, and the testing frame comprises a support frame and a testing system. The testing system comprises a liquid tank, a hydraulic pump connected to the output end of the liquid tank, a conveying pipe connected to the output end of the hydraulic pump, a plurality of branch pipes arranged on the conveying pipe, the plurality of branch pipes being fixed between every two adjacent columns of the support frame, a valve and a hydraulic gauge arranged on each of the plurality of branch pipes from top to bottom, a connecting head mounted on the output end of each of the plurality of branch pipes, two air cylinders arranged on a cross rod of the support frame and connected to each of the connecting heads, a slide rail frame fixed to the top of the support frame, an electric sliding block arranged on the slide rail frame, and a forward and reverse motor mounted on the bottom of the electric sliding block and connected to the output end of the electric sliding block.

[0013] According to the above technical solution, the hydraulic single prop test frame is provided, which comprises a support frame and a test system. The test system comprises a liquid tank, a storage container of liquid for testing the single prop, a hydraulic pump connected to the output end of the liquid tank, a kinetic energy output structure, and the like. When the single prop is tested, the kinetic energy is output to deliver the liquid in the liquid tank to the single prop under test, so as to test the single prop. The output end of the hydraulic pump is connected to a delivery pipe. Under the action of the hydraulic pump, the liquid is delivered to the total pipeline of each branch pipe. The delivery pipe is provided with a plurality of branch pipes. The liquid delivered by the delivery pipe is delivered to the pipeline of the single prop under test. The plurality of branch pipes are respectively fixed between two adjacent columns of the support frame, so as to provide strong support for the single prop between the two adjacent columns. The valve and the hydraulic gauge are arranged on the plurality of branch pipes from top to bottom. The valve plays a control role to control the opening and closing of the internal passage of the branch pipe, so as to control the delivery of the liquid. Only the connector corresponding to the single prop is delivered with the liquid. The hydraulic gauge detects the pressure on the branch pipe in real time during the delivery of the liquid, so as to indirectly detect the pressure in the single prop (the branch pipe is in communication with the single prop, so the pressure in the branch pipe is the pressure in the single prop). The output end of the plurality of branch pipes is provided with a connector, which plays a connecting role and is used for connecting the input end of the branch pipe and the single prop. The connector is provided on the crossbar of the support frame by two cylinders. The kinetic energy output structure outputs kinetic energy to drive the connector to move vertically. When the connector is connected to the single prop, the kinetic energy is output to drive the connector to move downward, so that the connector is connected to the input end of the single prop, the branch pipe is indirectly connected to the single prop, and the liquid is injected into the single prop, so as to provide strong support for the test. The top of the support frame is fixed with a slide rail frame. The electric sliding block moves along the rail. The electric sliding block is arranged on the slide rail frame. The moving structure moves under the control of the controller to drive the forward and reverse motor to move. After the single prop is lifted, the position of the single prop is adjusted. The electric sliding block at the bottom is provided with the forward and reverse motor. The kinetic energy output structure outputs kinetic energy to drive the steel rope reel to rotate in the reverse direction, so as to achieve the purpose of winding and unwinding the steel rope, thereby realizing the lifting of the single prop. The output end of the forward and reverse motor is connected to the steel rope reel. The frame body provided with the hook steel rope can realize the winding and unwinding of the steel rope under the action of the forward and reverse motor, so as to achieve the purpose of lifting and lowering the single prop.

[0014] The hydraulic pump, the valve, the hydraulic gauge, the air cylinder, the electric sliding block and the positive and negative motor are connected with the same controller, which plays a control role, controls the electric control elements such as the hydraulic pump, the valve, the hydraulic gauge, the air cylinder, the electric sliding block and the positive and negative motor to work cooperatively, and achieves the purpose of high-efficiency test of single column.

[0015] In summary, the application has the following beneficial effects:

[0016] 1. A sliding rail frame is installed on the top of the support frame. When the single column is transported, the controller is used to control the positive and negative motor to drive the steel rope reel to rotate, release the hook steel rope provided on the steel rope reel, hook the single column, then control the positive and negative motor to drive the steel rope reel to collect the rope, and hoist the single column in the air. The electric sliding block is used to easily hoist the single column to the placement area, slowly place and fix it. In this process, manual labor is not required, only the single column needs to be lightly supported, and the single column is not allowed to swing to avoid the risk of injuring workers. The operation is simple, efficient, and the labor intensity is small.

[0017] 2. The positive and negative motor adopts a servo motor, realizes closed-loop control of speed and torque, overcomes the out-of-step problem of a stepper motor, has strong overload capacity, can bear three times the rated torque load, meets the requirements of stable operation of the steel wire reel, and ensures stable transportation of the single column.
