The other end of the screw rod 23 is positioned outside the bracket 11 and fixedly connected with a hand wheel 25.
Working principle: in the initial state, the weight 5 is in a vertical state under the action of self gravity, and the bracket 11 is in a horizontal state. The third spring is in a natural state.
The crack detector 31 is mounted in a recess on the upper end surface of the bracket 11. Specifically, the crack detector 31 is placed between the two first clamping plates 10, the crack detector 31 pushes the two first clamping plates 10 to move away from each other, the first springs 27 are compressed to have elastic potential energy, and the crack detector 31 is clamped by the two first clamping plates 10 in the left-right direction. The hand wheel 25 is turned to move the second clamp plate 30 in a direction approaching the crack detector 31, so that the second clamp plate 30 is clamped by the cushion pad 26 and the second clamp plate 30 in the front-rear direction. The crack detector 31 is fixed in the bracket 11. When the crack detector 31 is detached from the bracket 11, the hand wheel 25 is turned to move the screw rod 23 in a direction away from the crack detector 31, and then the crack detector 31 can be taken out from the bracket 11 and stored. This is advantageous in protecting the crack detector 31 and preventing the crack detector 31 from being easily damaged by long-term exposure when not in use.
The rapid mounting and dismounting of the crack detector 31 can be realized by the method, which is beneficial to improving the detection efficiency.
After the crack detector 31 is installed, gas is filled into the annular tube 12 through the gas inlet nozzle 21, and the gas in the annular tube 12 enters the connecting cylinder 8 through the gas tube 7, so that a certain positive pressure is formed in the connecting cylinder 8. But the positive pressure does not affect the swinging of the weight 5, the weight 5 can still swing freely,
the device is moved to the destination to be measured by means of the roller 1. The motor 18 is started, the motor 18 rotates the screw rod 16 through the second bevel gear 20 and the first bevel gear 17, the third sleeve 15 moves upwards, the mounting plate 4 drives the bracket 11 to move upwards through the supporting frame, and the crack detector 31 rises to a proper detection position.
During the movement of the device, the weight 5 swings under the action of its own weight and inertia. Assuming that the weight 5 swings to the right, the right damper is shortened. In the right telescopic assembly, the second guide rod 9 moves into the corresponding connecting cylinder 8, and presses the gas in the connecting cylinder 8, so that the gas in the connecting cylinder 8 flows into the annular pipe 12 through the gas pipe 7. Since the inner diameter of the air pipe 7 is smaller than the inner diameter of the connecting cylinder 8, the air pressure in the connecting cylinder 8 is gradually increased, and the resistance applied when the second guide rod 9 slides into the connecting cylinder 8 is gradually increased. The downward moving speed of the second guide bar 9 is buffered, and the rightward swinging speed of the weight 5 is further reduced. That is, the weight 5 is blocked by the right buffer assembly during the rightward swinging, so that the rightward swinging amplitude of the weight 5 is reduced.
While the left side cushioning assembly is extended. In the left-hand buffer assembly the second guide rod 9 is moved outwards along the connecting cylinder 8 and the gas in the annular tube 12 is fed into the connecting cylinder 8 via the gas tube 7. Because the internal diameter of the air pipe 7 is smaller than the internal diameter of the connecting cylinder 8, the air pressure in the connecting cylinder 8 is gradually reduced, and when the connecting cylinder 8 is in a negative pressure state, the second guide rod 9 moves outwards to receive the resistance of the negative pressure, so that the swinging effect of the heavy hammer 5 is prevented, and the swinging amplitude of the heavy hammer 5 is further reduced.
In the process of extending or shortening the buffer component, the lower end of the connecting cylinder 8 rotates around the first spherical hinge seat, the upper end of the second guide rod 9 rotates around the corresponding second spherical hinge seat, the third spring is elastically deformed, the action of buffering the action of the telescopic component is achieved, and then the swing of the heavy hammer 5 is buffered.
Similarly, when the weight 5 swings leftwards, the swing amplitude of the weight 5 is further reduced. Therefore, under the action of the buffer component, the weight 5 can be quickly stabilized and kept in a vertical state, so that the crack detector 31 is quickly stabilized.
During the movement of the device, if the device is subjected to uneven road surfaces, the device is made to shake, and when the device shakes up and down, the connecting rod 13 moves up and down along the second sleeve 14, and the second spring 29 has a buffering effect on the movement of the connecting rod 13, so that the movement of the mounting shell 24 is buffered, and the swinging of the ball 28 is slowed down.
Although the present invention has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present invention.
