[0049] Furthermore, in the above structure, the power component 004 includes a cavity 401, which is opened on the inner wall of the through cavity 104 and located at the center of the through cavity 104. An annular groove 402 is opened on the inner wall of the cavity 401. A placement plate 403 is arranged in the cavity 401. A positioning ring 404 is fixedly sleeved on the outer side of the placement plate 403. The positioning ring 404 is slidably connected to the annular groove 402. A positioning hole 406 is opened at the center of the placement plate 403. A positioning rod 405 is connected through the positioning hole 406. The upper part of the positioning rod 405 is rotatably connected to the lower part of the remote sensing imaging probe 103, and the remote sensing imaging probe 103 is rotatably connected to the upper part of the placement plate 403.

[0050] Through the cooperation of the annular groove 402 and the positioning ring 404, the placement plate 403 can rotate 360° in the cavity 401, and the remote sensing imaging probe 103 can rotate 90° above the placement plate 403, so as to stand upright above the placement plate 403. During the rotation, the positioning rod 405 below the remote sensing imaging probe 103 moves downward along the positioning hole 406.

[0051] Furthermore, in the above structure, a bevel gear 407 is fixedly connected below the positioning rod 405, and the bevel gear 407 is arranged below the placement plate 403, a placement plate 408 is fixedly connected to the inner wall of the cavity 401, and the placement plate 403 and the placement plate 408 are arranged up and down, a motor 409 is installed above the placement plate 408, and a bevel gear 2 410 is installed at the output end of the motor 409, the bevel gear 2 410 and the bevel gear 407 are in the same vertical position, and a double-headed bevel gear shaft 411 is meshed below the bevel gear 2 410, and the double-headed bevel gear shaft 411 is connected through the center position of the placement plate 408.

[0052] The motor 409 can drive the bevel gear 2 410 to rotate, so that the bevel gear 2 410 drives the double-headed bevel gear shaft 411 to rotate, and when the bevel gear 1 407 moves downward on the positioning rod 405, it will fit into the top of the bevel gear 2 410 and engage, so that the bevel gear 2 410 can drive the bevel gear 1 407 to rotate, so that the remote sensing imaging probe 103 rotates as a whole, thereby completing the image acquisition of the steel structure without blind spots.

[0053] Furthermore, in the above structure, the auxiliary component 005 includes a sleeve 501, which is rotatably connected to the bottom of the placement plate 408, and a bevel gear three 502 is fixedly connected to one side of the sleeve 501, and the bevel gear three 502 is meshed with the bottom of the double-headed bevel gear shaft 411.

A limit groove 505 is symmetrically opened on the inner wall of the sleeve 501, and the limit groove 505 is slidably connected to the corresponding limit block 504.

[0054] The double-headed bevel gear shaft 411 can drive the bevel gear three 502 to rotate, thereby rotating the sleeve 501, and through the cooperation of the limit block 504 and the limit groove 505, the sleeve 501 can drive the push rod 503 to rotate, and the push rod 503 can slide within the sleeve 501.

[0055] Furthermore, in the above structure, a push ring 506 is sleeved and fixed on the push rod 503, and a spring three 507 is sleeved on the push rod 503. One side of the spring three 507 is fitted with the push ring 506, and the side of the spring three 507 away from the push ring 506 is fitted with the sleeve 501.

[0056] The push ring 506 is pushed by spring three 507, so that the push rod 503 can slide in the sleeve 501, so that the bevel gear four 508 is always in a state of meshing with the bevel gear disk 509, and because the inclination angle of the bevel gear disk 509 is large, when the bevel gear disk 509 rotates away from the bevel gear four 508 as the roller 304 rotates, the bevel gear four 508 will move under the action of spring three 507, but when the bevel gear disk 509 is reset, the bevel gear disk 509 will still mesh with the bevel gear four 508, and as the bevel gear disk 509 continues to move, it pushes the push rod 503 on one side of the bevel gear four 508 to move into the sleeve 501, so that the power of the motor 409 can be transmitted to the roller 304.

[0057] like Figure 1-9As shown, by inserting a single steel bar between the guide frame 311 and the guide wheel 310 and continuously entering between the two groups of rollers 304, the motor 409 is rotated at this time, so that the motor 409 drives the double-headed bevel gear shaft 411 to rotate through the bevel gear second 410, so that the double-headed bevel gear shaft 411 drives the bevel gear third 502 to rotate, and drives the bevel gear plate 509 to rotate through the bevel gear fourth 508 on one side, so that a group of rollers 304 rotates, so that the steel bar can continue to move along the through cavity 104. At this time, since the irradiation direction of the remote sensing imaging probe 103 is facing the through cavity 104, the remote sensing imaging probe 103 can scan and image the steel bar, and extract and measure the size. When it is necessary to measure the overall steel bar structure, the motor 409 is turned off at this time, and the bidirectional screw 205 is rotated by rotating the manual turntable 206, so that the two groups of connecting shafts 202 drive the rollers 304 to rotate, so that the rollers 304 will The base 001 is propped up as a whole, at which time the bevel gear disc 509 and bevel gear four 508 are disengaged, and the remote sensing imaging probe 103 is rotated 90° to make it vertical to the base 001. During the rotation, the positioning rod 405 will slide along the positioning hole 406, so that the bevel gear one 407 and the bevel gear two 410 are engaged. At this time, the base 001 is pushed to the position to be measured by the handle 102, and the motor 409 is turned on to make the bevel gear two 410 drive the bevel gear one 407 to rotate, so that the remote sensing imaging probe 103 is rotated 360°, the steel structure is scanned and imaged, and the size is extracted by image processing technology, thereby completing the overall measurement of the steel structure. Through this structure, the measurement and supervision of single steel bars and the overall structure can be completed according to the measurement requirements, and the surveying and mapping modes of the equipment can be switched freely, and the operation is convenient, which greatly improves the efficiency of steel engineering supervision and the convenience of equipment operation.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
