However, the single hydraulic prop cannot meet the calibrated pressure requirement and has the problem of leakage of sealing liquid when the pressure of the working face is high, and the potential safety hazard exists in continuous use.
Disclosure of Invention
For solving at present to hydraulic prop only can suppress experimental and appear the hydraulic prop that drops into the use again and appear the technical problem of sealed weeping, the utility model provides a hydraulic prop's pressure test device.
In order to solve the technical problem, the utility model discloses a technical scheme is:
the utility model provides a pressure test device of hydraulic prop, its includes frame, hydraulic cylinder, oil pipe, manometer, first lift cylinder, second lift cylinder, first fastener and second fastener, wherein: the hydraulic lifting oil cylinder is characterized in that the frame is U-shaped, the middle part of one side of the frame is connected with a cylinder body of the hydraulic oil cylinder, an oil outlet of the hydraulic oil cylinder is connected with one end of an oil pipe, the pressure gauge is fixed at the top of one side of the frame, the other end of the oil pipe is connected with the pressure gauge, the cylinder bodies of the first lifting oil cylinder and the second lifting oil cylinder are respectively connected with two sides of the bottom of the frame, the machine bodies of the first fastener and the second fastener are connected with the frame, a brake pad of the first fastener is connected with a piston rod of the first lifting oil cylinder, and a brake pad of the second fastener is connected with a piston rod of the second lifting oil cylinder.
Optionally, the first and second fasteners are both brakes.
The utility model has the advantages that:
frame, hydraulic cylinder, oil pipe, manometer, first lift cylinder, second lift cylinder, first fastener and second fastener are drawn together through the setting, provide one kind and can take the device of area pressure test to hydraulic prop, before hydraulic prop goes into the pit, pressure measurement is taken in area to usable the device, guarantees that the pressure of the hydraulic prop of going into the pit satisfies the production requirement and sealed weeping problem can not appear. This device passes through hydraulic prop extrusion hydraulic cylinder, detects the oil pressure through the manometer, can confirm whether hydraulic prop satisfies the pressure requirement, simple structure, convenient operation, and the practicality is strong, and the preparation is convenient, and the cost of manufacture is low.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1, the pressure testing apparatus for a single hydraulic prop in this embodiment includes a frame 1, a hydraulic cylinder 2, an oil pipe 3, a pressure gauge 4, a first lift cylinder 5, a second lift cylinder 7, a first fastener 8, and a second fastener 9, wherein: the frame 1 is U-shaped, the middle part of one side of frame 1 is connected with hydraulic cylinder 2's cylinder body, hydraulic cylinder 2's oil-out is connected with 3 one end of oil pipe, manometer 4 is fixed at one side top of frame 1, the oil pipe 3 other end is connected with manometer 4, the cylinder body of first lift cylinder 5 and second lift cylinder 7 is connected with frame 1 bottom both sides respectively, the organism of first fastener 8 and second fastener 9 all is connected with frame 1, the brake block of first fastener 8 is connected with the piston rod of first lift cylinder 5, the brake block of second fastener 9 is connected with the piston rod of second lift cylinder 7.
When the first lifting oil cylinder 5 and the second lifting oil cylinder 7 lift, piston rods of the first lifting oil cylinder and the second lifting oil cylinder drive brake pads of the first fastening piece 8 and the second fastening piece 9 to open and close respectively.
Optionally, the first fastener 8 and the second fastener 9 are both brakes.
The utility model discloses when using, earlier control the operating valve of first lift cylinder 5 and make the brake block motion that first lift cylinder 5 rises and drive first fastener 8 realize holding tightly fixedly to hydraulic cylinder 2, then place monomer hydraulic prop 6 in frame 1, let the one end of monomer hydraulic prop 6 withstand the opposite side of frame 1, let the other end of monomer hydraulic prop 6 withstand pressure cylinder 2, then control the operating valve of second lift cylinder 7 and make the brake block motion that second lift cylinder 7 rises and drive second fastener 9 realize holding tightly fixedly to monomer hydraulic prop 6. Next, the single hydraulic prop 6 is pressurized through the emulsion pump station, the pressure value of the pressure gauge 4 in the pressurization process of the single hydraulic prop 6 is observed, and whether the pressure value meets the calibration pressure requirement of the single hydraulic prop 6 or not is determined.
The utility model discloses a 6 extrusion hydraulic cylinder 2 of hydraulic prop, through the oil pressure that manometer 4 detected hydraulic prop 6, and then confirm whether hydraulic prop 6 satisfies the pressure requirement to the area to hydraulic prop 6 of monomer test has been realized pressing. Through the test of taking the pressure, the problem of hydraulic leakage under the sealed pressure of hydraulic prop 6 has been solved to a great extent, has guaranteed hydraulic prop 6's the support quality of holding.
Before going into the well, it is usable the utility model discloses carry out the area to the hydraulic prop 6 that goes into the well and press pressure detection, guarantee that the pressure of hydraulic prop 6 satisfies the production requirement.
It is to be understood that the above embodiments are merely exemplary embodiments that have been employed to illustrate the principles of the present invention, and that the present invention is not limited thereto. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and substance of the invention, and these modifications and improvements are also considered to be within the scope of the invention.
