The outer wall of the inner piston 7 of the second gas-liquid damping cylinder 2 is provided with a magnetic ring, the inner wall of the outer piston 8 of the second gas-liquid damping cylinder 2 is also provided with a magnetic ring, and the outer piston 8 moves synchronously along with the inner piston 7 under the attraction of magnetic force. The outer piston 8 is fixedly connected with the moving plate 11 through bolts, the drilling machine 9 is fixed on the moving plate 11, the moving plate 11 passes through the two guide rods 12 and can move back and forth along the guide rods 12, two sides of the first gas-liquid damping cylinder 1, the second gas-liquid damping cylinder 2 and the guide rods 12 are fixed into a whole through mounting plates, and the manual reversing valve 10 and the speed regulating valve 3 are respectively mounted on the two mounting plates at two ends. The guide rod 12 can resist the torque of the drilling machine 9 during drilling, the guide rod 12 is hollow, and the rigidity of the guide rod is improved while the mass is reduced. When the second gas-liquid damping cylinder 2 extends or retracts, the outer piston 8 drives the drilling machine 9 to synchronously move with the inner piston 7.
In the invention, gas is filled in the right cavity (gas cavity) of the first gas-liquid damping cylinder 1 and the left cavity (gas cavity) of the second gas-liquid damping cylinder 2, and oil is filled in the left cavity (liquid cavity) of the first gas-liquid damping cylinder 1 and the right cavity (liquid cavity) of the second gas-liquid damping cylinder 2. The left cavity of the first gas-liquid damping cylinder 1 is communicated with the right cavity of the second gas-liquid damping cylinder 2 through a one-way valve 6 and a speed regulating valve 3. The manual reversing valve 10 is a three-position four-way reversing valve, and a lower air hole at one end of each position of the three-position four-way reversing valve, which is opposite to the air-liquid damping cylinder, is connected with an air source; two air holes at one end of each position of the three-position four-way reversing valve, which faces towards the gas-liquid damping cylinder, are respectively connected with the gas cavity of the first gas-liquid damping cylinder 1 and the gas cavity of the second gas-liquid damping cylinder 2. When the air source is communicated with the lower air hole at the upper position, as shown in fig. 1, air enters from the air cavity of the first air-liquid damping cylinder 1, the piston in the first air-liquid damping cylinder 1 is pushed to move towards the liquid cavity of the first air-liquid damping cylinder, and then the liquid in the liquid cavity of the first air-liquid damping cylinder 1 enters into the liquid cavity of the second air-liquid damping cylinder 2 through the speed regulating valve 3; when the air source is communicated with the lower air hole at the lower position, air enters from the air cavity of the second air-liquid damping cylinder 2, the inner piston 7 of the second air-liquid damping cylinder 2 is pushed to move towards the liquid cavity of the second air-liquid damping cylinder, and liquid in the liquid cavity of the second air-liquid damping cylinder 2 enters into the liquid cavity of the first air-liquid damping cylinder 1 through the one-way valve 6.
When the pneumatic hydraulic damper works, the manual reversing valve 10 is driven to an upper position, high-pressure gas enters the right cavity of the first pneumatic damping cylinder 1 to push oil in the left cavity, oil enters the right cavity of the second pneumatic damping cylinder 2 through the speed regulating valve 3 to push the inner piston 7 to move, and then the movable plate 11 is driven to move through the coupling magnetic ring, and the drilling machine 9 fixed on the movable plate 11 realizes drilling feeding movement. When the speed regulating valve 3 is in a stable working state, the pressure difference delta P=P1-P2 at two sides of the throttle valve 5 is kept constant, when the load of the drilling machine 9 is increased, the right side pressure P2 of the throttle valve 5 is increased to reduce delta P, the valve port opening of the constant difference reducing valve 4 is increased, the liquid resistance is reduced, the left side pressure P1 of the throttle valve 5 is increased, and delta P is automatically raised; when the load of the drilling machine 9 is reduced, the P2 is reduced to increase the delta P, the valve port of the constant-difference pressure reducing valve 4 is reduced, the liquid resistance is increased, the P1 is lowered, and the delta P is lowered, so that the automatic adjustment ensures that the flow entering the right cavity of the second gas-liquid damping cylinder 2 is constant, and the constant-speed feeding work of the drilling machine is realized. When the manual reversing valve 10 is in the lower position, the oil in the right cavity of the second gas-liquid damping cylinder 2 returns quickly through the one-way valve 6, and the inner piston 7 retracts quickly.
The whole structure of the constant-speed drilling cuttings measuring device is shown in fig. 5, the drilling machine 9 and the moving plate 11 are fixed together, and the moving plate 11 can drive the drilling machine 9 to move along the guide rod 12. The integrated structure formed by the first gas-liquid damping cylinder 1, the second gas-liquid damping cylinder 2, the speed regulating valve 3 and the manual reversing valve 10 is connected with the tripod 13 through a pin shaft, the side surface of the lower end of the integrated structure formed by the first gas-liquid damping cylinder 1, the second gas-liquid damping cylinder 2, the speed regulating valve 3 and the manual reversing valve 10 is provided with a fixed plate 14, three positioning holes are formed in the fixed plate 14, and when different positioning holes are selected, the angles of the drilling machine 9 and the tripod 13 are different when the drilling machine 9 contacts, so that the dip angle of the drilling machine 9 drilling into a coal wall can be adjusted. When in operation, the angle at which the three legs of tripod 13 open can be adjusted to adjust the height of rig 9. After the open angle of the legs of the tripod is determined, the tripod is connected with the fixing pins 15 on the legs of the tripod 13 through the triangular plate 19, so that the open angle of the tripod 13 is fixed, the height of the drilling machine 9 is determined accordingly, then the fixing plate 14 is penetrated into the fixing pins 15 on the top of the tripod 13, then the iron chain 17 is fixed on the hanging ring 16 fixed on the fixing plate 14, the other end of the iron chain 17 is fixed on the anchor rod 18 of the coal wall, and an operator holds the handrail 20 on the mounting plate to ensure the stability of the drilling cutting device. When the constant-speed drilling cutting device does not work, the tripod is retracted, so that occupied space is reduced, and the carrying is convenient.
After the device is installed, the air pump is used for providing power for the air-liquid damping cylinder, when the high-pressure air pushes the inner piston 7 of the second air-liquid damping cylinder 2 to move, the magnetic force of the magnetic ring can attract the outer piston 8 to drive the moving plate 11 to move simultaneously, the drilling machine 9 is in contact with the coal wall, and the coal wall is drilled at a constant speed. After the drill rod is completely drilled into the coal wall, the drill rod is taken down, the gas-liquid damping cylinder is quickly retracted, a drill rod can be connected between the drilling machine 9 and the drill rod drilled into the coal wall, the drilling machine 9 is pushed to extend out to continue drilling cuttings, and a plurality of drill rods can be connected until the depth of the drilling cuttings is reached. And after the operation is finished, the drill rod is taken down, the piston of the gas-liquid damping cylinder is quickly retracted, and the drilling is finished.
