An elastic member 111 is provided on the outer end of the electromagnet 113, and an oblique clamping block 112 is connected to the outer end of the elastic member 111. The switch 82 controls the electromagnet 113 to be energized, and the electromagnet 113 is energized to generate a magnetic force to attract the oblique clamping block 112, so that the oblique clamping block 112 slides laterally away from the lower seat 9 in the groove of the base 11, and compresses the elastic member 111 to generate a reverse elastic force, and the telescopic device 10 continues to shorten to drive the lower seat 9 to move upward and abut against the heat protection cover 4, and the lower limit portion 41 is relatively inserted into the lower limit hole 91.

[0027] More specifically, the upper seat 8 has an upper limit hole 81 on the bottom wall, and the inner wall of the heat shield 4 has an upper limit portion 42 that matches the upper limit hole 81. The upper limit portion 42 of the inner bottom wall of the heat shield 4 is relatively inserted into the upper limit hole 81 of the bottom wall of the upper seat 8, and the upper limit portion 42 is inserted into the upper limit hole 81 to trigger the switch 82.

[0028] More specifically, the top wall of the lower seat 9 is provided with a lower limit hole 91, and the outer wall of the heat shield 4 is provided with a lower limit portion 41 adapted to the lower limit hole 91.

[0029] To be more specific, a switch 82 for controlling the electromagnet 113 is installed inside the upper limit hole 81 .

[0030] The working principle of the utility model is as follows: when in use, through grooves are horizontally opened on the front and rear walls of the protective cover 4, and the round steel to be inspected passes through the through grooves under the transportation of the rollers 1 arranged in a line, and four groups of 3D line scanning lasers 6 each occupy a quadrant and are arranged at an angle of 90° and installed on the mounting plate 5 and relatively located inside the heat protection cover 4, a group of 3D laser measuring instruments 6 includes a line scanning laser, a linear array CCD camera and a planar array CCD camera, and tempered glass corresponding to the 3D line scanning laser 6 is installed on the through grooves opened in the protective cover 4, and the four groups of 3D line scanning lasers 6 measure different parts of the round steel to be inspected through the corresponding tempered glass, and the slide rail 3 and the translation device 2 are relatively fixed on the ground, and the heat protection cover 4 is moved on the slide rail 3 through the slider The heat shield 4 can be connected to the heat shield 4 by a hydraulic push rod, so that the translation device 2 drives the heat shield 4 to move between the two groups of rollers 1 or to separate. When the heat shield 4 moves between the two groups of rollers 1, the round steel conveyed on the roller 1 passes through the through groove, and the heat shield 4 moves away from the roller 1, which is convenient for repairing and replacing the components inside the heat shield 4. The base 11 is fixed on the ground, the upper seat 8 is relatively located inside the heat shield 4, and the lower seat 9 is relatively located outside the heat shield 4. The telescopic device 10 can adopt an electric push rod or a hydraulic push rod, and its two ends are respectively connected to the upper seat 8 and the lower seat 9. The mounting plate 5 is relatively located inside the heat shield 4 and has no direct connection with the heat shield 4. There is a A plurality of shock-absorbing springs 7, when the telescopic device 10 is extended, the upper seat 8 and the components above it are first pushed downward by the gravity of the lower seat 9 to move away from the outer bottom wall of the heat shield 4, so that the lower seat 9 and the base 11 are connected as a whole, and then the telescopic device 10 continues to extend to push the upper seat 8 to move up a distance away from the inner bottom wall; at this time, the upper seat 8, the lower seat 9, the telescopic device 10, and the mounting seat 5 are not directly connected to the heat shield 4, and the vibration received by the heat shield 4 will not be transmitted to the 3D line scanning laser 6 on the mounting plate 5. At this time, the vibration that the 3D line scanning laser 6 can receive comes from the vibration of the base 11 received by the ground, and this vibration can be damped by the shock-absorbing springs 7. When the heat shield 4 needs to move, the telescopic device 10 is controlled to shorten. At this time, the lower seat 9 and The base 11 is relatively fixedly connected, thereby driving the upper seat 8 to descend and abut against the heat shield 4, and the upper limit portion 42 of the inner bottom wall of the heat shield 4 is relatively inserted into the upper limit hole 81 of the bottom wall of the upper seat 8, and the upper limit portion 42 is inserted into the upper limit hole 81 to trigger the switch 82, and the switch 82 controls the electromagnet 113 to be energized, and the electromagnet 113 is energized to generate a magnetic force to attract the oblique clamping block 112, so that the oblique clamping block 112 slides laterally away from the lower seat 9 in the groove of the base 11, and compresses the elastic member 111 to generate a reverse elastic force, and the telescopic device 10 continues to shorten and drives the lower seat 9 to move upward and abut against the heat shield 4, and the lower limit portion 41 is relatively inserted into the lower limit hole 91; the upper seat 8 and the lower seat 9 cooperate to clamp the heat shield 4, and the lower seat 9 is upwardly separated from the base 11;Thus, the mounting plate 5 is relatively fixed in the heat shield 4 and can move with the heat shield 4. A groove A is provided on the top of the base 11. The shape of the groove A is adapted to the structure of the lower seat 9 as a non-circular structure. When the lower seat 9 slides down vertically and extends into the groove A of the base 11, the lower seat 9 abuts against the inclined surface of the oblique clamping block 112, pushing the oblique clamping block 112 to move relatively horizontally on the base 11 and compressing the elastic member 111 until the lower seat 9 moves vertically downward and completely crosses the oblique clamping block 112, and the bottom wall of the lower seat 9 just abuts against the bottom wall of the groove of the base 11. The oblique clamping block 112 is reset under the push of the reverse elastic force of the corresponding elastic member 111. At this time, the oblique clamping block 112 limits the lower seat 9 to be separated from the base 11 upward, thereby realizing that the lower seat 9 and the base 11 are fixedly connected as one. ;

[0031] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
