The outer surface of the rod 3 is threadedly connected, the bottom of the connecting frame 501 is fixedly connected to a mounting plate 505, the inner surface wall of the mounting plate 505 is slidably connected to connecting rods 507 near the four corners, the bottoms of the multiple connecting rods 507 are fixedly connected to touch plates 509, the inner surface of the mounting plate 505 is provided with a pressure detector 510, the pressure detector 510 and the touch plate 509 are matched, the outer surfaces of the multiple connecting rods 507 are respectively sleeved with springs 508, the tops of the multiple connecting rods 507 are fixedly connected to the connecting plate 506, and the clamping assembly 6 includes a first The fixing frame 601, the first fixing frame 601 is fixedly connected to the inner bottom of the mounting frame 1, the rear surface of the first fixing frame 601 is fixedly connected to the second fixing frame 602, the inner surface wall of the second fixing frame 602 is rotatably connected with a bidirectional threaded rod 607, the outer surface of the bidirectional threaded rod 607 is symmetrically provided with a second connecting block 606, the inner surfaces of the two second connecting blocks 606 are both threadedly rotatably connected with the outer surface of the bidirectional threaded rod 607, the front surfaces of the two second connecting blocks 606 are respectively fixedly connected with a clamping block 603, and the spring 508 is located between the touch plate 509 and the mounting frame 1. Between the relative outer surfaces of the mounting plate 505, the spring 508 and the touch plate 509 are matchedly arranged, the inner top of the mounting frame 1 is symmetrically fixedly connected with the first guide rod 4, the outer surfaces of both sides of the connecting frame 501 are respectively fixedly connected with the sliding sleeves 504, the inner surface of the sliding sleeve 504 is slidably connected to the outer surface of the first guide rod 4, the inner wall of the first fixing frame 601 is fixedly connected with the second guide rod 605, the front surfaces of the two clamping blocks 603 are respectively fixedly connected with the first connecting blocks 604, and the inner surfaces of the two first connecting blocks 604 are both slidably connected to the outer surface of the second guide rod 605.

[0024] The effect achieved by the entire embodiment 1 is that when the hydraulic support column jack is subjected to pressure testing, the hydraulic support column jack to be tested is first placed between the two clamping blocks 603, and a handle on one side of the bidirectional threaded rod 607 is held and rotated clockwise to rotate it in the second fixing frame 602. The two second connecting blocks 606 move toward each other on the outer surface of the bidirectional threaded rod 607, and the two clamping blocks 603 move toward each other synchronously along the outer surface of the second guide rod 605 through the two first connecting blocks 604. The two clamping blocks 603 will contact the first The surface of the jack to be tested in the fixing frame 601 is squeezed to play a clamping and fixing role to prevent it from tipping over during the test. When the motor 2 fixed on the top of the mounting frame 1 is started, the output end of the motor 2 drives the first threaded rod 3 to rotate clockwise, and the threaded sleeve 502 moves downward on its surface, and the connecting frame 501 slides downward synchronously along the surfaces of the two first guide rods 4 through the two sliding sleeves 504. Due to the continuous extension of the springs 508 sleeved on the surfaces of the multiple connecting rods 507, the touch plate 509 at the bottom will First, it contacts the telescopic end of the jack to be tested. Then, under the continuous downward movement of the connecting frame 501, multiple springs 508 are deformed and contracted, and the pressure detector 510 fixedly set in the mounting plate 505 and extending downward will conflict with the touch plate 509. Under the interaction force, the downward thrust continuously generated by the connecting frame 501 acts on the telescopic end of the test jack. At the same time, the pressure detector 510 will be subjected to the same reverse force for testing, and the motor 2 is driven in the reverse direction to rotate its output end counterclockwise, and the connecting frame 501 moves upward. Reset, driving the pressure detector 510 to move upward in a small range, and multiple springs 508 push the touch plate 509 away from the pressure detector 510 under the elastic stretching and resetting action. The connecting plate 506 limits the multiple connecting rods 507, so that the pressure detector 510 is temporarily separated from the touch plate 509, and the motor 2 is driven forward again, so that the pressure detector 510 will resist the test again. After repeated measurements for many times, the average value is taken and compared with the standard pressure to complete the test. During the test, no personnel support and manual testing are required, which reduces the workload of personnel.

[0025] Embodiment 2, as Figure 1-Figure 4 As shown, the length of the first guide rod 4 is greater than the height of the connecting frame 501, the length of the first threaded rod 3 is less than the height of the connecting frame 501, the bottom center of the touch plate 509 is concave, and the top center of the touch plate 509 is convex.

[0026] The effect achieved by the entire embodiment 2 is that, when in use, a longer first guide rod 4 is symmetrically fixed on the inner top of the mounting frame 1, and the length of the first threaded rod 3 is slightly shorter than the mounting frame 1, so as to avoid the connection frame 501. When the motor 2 is overdriven, the bottom of the first threaded rod 3 will collide with the top of the pressure detector 510.

The raised area on the top of the touch plate 509 is made of rubber material.

[0027] Working principle: During the pressure test, the hydraulic support column jack to be tested is placed vertically into the inner bottom of the mounting frame 1 so that it is located between the two clamping blocks 603. The two-way threaded rod 607 is held and rotated clockwise. The two second connecting blocks 606 move toward each other on the outer surface of the two-way threaded rod 607, driving the two clamping blocks 603 to move synchronously. The relative arc-shaped outer surfaces of the two clamping blocks 603 will squeeze the surface of the jack to be tested in the first fixing frame 601, playing a clamping and fixing role. The motor 2 is started, and the motor When the output end of the connecting frame 501 drives the first threaded rod 3 to rotate clockwise, the connecting frame 501 will move downward along the two first guide rods 4 through the two sliding sleeves 504 under the action of the threaded rotation connection of the threaded sleeve 502, and the touch plate 509 at the bottom will first contact the telescopic end of the jack to be tested. Under the continuous downward movement of the connecting frame 501, the mounting plate 505 will be squeezed by the multiple springs 508 to cause it to deform and shrink, and the pressure detection gauge 510 fixed at the center of its bottom will conflict with the touch plate 509, and the connecting frame 501 will be moved downward. 01 continuously generates a downward thrust, which acts on the telescopic end of the test jack under the interaction force. At the same time, the pressure detector 510 will be subjected to the same reverse force for testing, and the motor 2 will be driven in the reverse direction to rotate its output end counterclockwise, and the connecting frame 501 will move upward and reset, driving the pressure detector 510 to move upward in a small range. Under the elastic extension and reset action, multiple springs 508 push the touch plate 509 away from the pressure detector 510. The connecting plate 506 limits the multiple connecting rods 507, so that the pressure detector 510 is temporarily separated from the touch plate 509, and the motor 2 is driven forward again, so that the pressure detector 510 will resist the test again. After repeated measurements for many times, the average value is taken and compared with the standard pressure to complete the test. During the test, no personnel support and manual testing are required, which solves the problem that the cam needs to be manually rotated manually in the background technology. When the cam is in vertical contact with the cross plate, the handle is rotated again to reset the cam, which requires a large force to pull. Repeated manual rotation can easily put too much burden on the hands of personnel, increasing the work intensity of personnel.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
