[0023] The above scheme is adopted: the steel pipe 2 is fixed above the double-rope hoisting motor 1, the double-rope hoisting motor 1 and the steel pipe 2 are fixed to the cast-in-place beam bracket in a detachable manner, the wire rope 6 is rolled out from the receiving roller 5, and the vertical transmission direction is converted to the horizontal transmission direction by the fixed pulley 4 welded on the steel pipe 2. The flat head screw 71 is screwed into the screw hole to tighten the wire rope 6, and the pan-tilt head 7 and the wire rope 6 are connected together. The non-destructive testing instrument is fixed on the pan-tilt head 7 to realize remote control of the double-rope hoisting motor 1 and the non-destructive testing instrument for inspection without the need for maintenance personnel to enter the cast-in-place beam bracket. The double-rope hoisting motor 1 and the non-destructive testing instrument are remotely controlled for inspection. The arrangement of the double-rope hoisting motor 1, the steel pipe 2, the fixed pulley 4 and the receiving roller 5 and other structures can prevent personnel from entering the dangerous area and reduce the occurrence of accidents. The probability of occurrence is high, the double-rope hoisting motor 1 is fixed on the cast-in-place beam support, the steel pipe 2 is above the double-rope hoisting motor 1 and fixed on the cast-in-place beam support, the wire rope 6 is wound out by the double-rope hoisting motor 1 at one end, and the transmission direction is changed to horizontal by the fixed pulley 4 fixed on the steel pipe 2, the wire rope 6 passes through the cast-in-place beam support along the longitudinal direction of the box beam, and is wound into the double-rope hoisting motor 1 at the other end, and the vertical positions of the steel pipes 2 at both ends are adjusted to be consistent, and the transmission direction of the wire rope 6 is kept horizontal. It is suitable for non-destructive testing of the box beam when the cast-in-place beam support has not been removed during the construction phase. Maintenance personnel do not need to enter the inside of the support, and the pan / tilt head 7 with the non-destructive testing instrument fixed is transmitted to the corresponding position of the box beam for testing through the double-rope hoisting motor 1.
[0024] like Figures 1 to 5 As shown, the double-rope hoisting motor 1 and the steel pipe 2 are detachably fixed to the cast-in-place beam support. The length of the steel pipe 2 is greater than the double-rope spacing. The steel wire rope 6 is uniformly transmitted in the direction of the steel wire rope 6 through the fixed pulley 4. The steel pipe 2 is located above the double-rope hoisting motor 1. The fixed pulley 4 is fixed above the steel pipe 2 by welding. The line connecting the rotation axis of the fixed pulley 4 and the welding point is 45 degrees to the vertical direction to realize the transformation of the transmission direction of the steel wire rope 6 from vertical to horizontal.
[0025] The above solution is adopted: the double-rope hoisting motor 1 provides power, and the rotation of the output end drives the storage roller 5 to rotate, thereby winding or releasing the wire rope 6, thereby controlling the movement of the pan-tilt platform 7.

One end of the storage roller 5 is fixedly connected to the fixed block 51, and one end of the fixed block 51 is fixedly connected to the rotating shaft 52, and the rotating shaft 52 is rotatably connected to the cast-in-place beam bracket. Both ends of the steel pipe 2 are fixedly connected to the connecting rod 21 through a threaded sleeve, and one end of the connecting rod 21 is fixedly connected to the mounting block 22. A clamping block 23 is provided at the bottom of the mounting block 22, and a positioning bolt is provided inside the clamping block 23.

The mounting member 91 is connected to the double-rope winch motor 1 through a limit bolt, and a spring 93 is fixedly installed on one side of the clamping member 92.
[0027] Adopt the above scheme: the height of the detection instrument can be appropriately adjusted by extending and retracting the supporting telescopic rod 9; the mounting part 91 can fix the double-rope winch motor 1; the cooperation of the clamping part 92 and the spring 93 can ensure the stability of the storage roller 5 during movement; the fixing block 51 connects the storage roller 5 with the rotating shaft 52; the rotating shaft 52 is rotatably connected to the cast-in-place beam bracket to provide support for the rotation of the storage roller 5, so that the storage roller 5 can rotate stably under the drive of the double-rope winch motor 1; the connecting rod 21 is connected to the steel pipe 2 through a threaded sleeve, which increases the installation flexibility of the steel pipe 2; the clamping block 23 and the positioning bolt at the bottom of the mounting block 22 can firmly fix the entire device on the cast-in-place beam bracket, ensuring the stability and safety of the device during operation.
[0028] The working principle and usage process of the utility model are as follows: the double-rope hoisting motor 1 is fixed on the cast-in-place beam support, the steel pipe 2 is above the double-rope hoisting motor 1 and fixed on the cast-in-place beam support, the steel wire rope 6 is wound out by the double-rope hoisting motor 1 at one end, and the transmission direction is changed to horizontal by the fixed pulley 4 fixed on the steel pipe 2, the steel wire rope 6 passes through the cast-in-place beam support along the longitudinal direction of the box beam, and is wound into the double-rope hoisting motor 1 at the other end, and the vertical positions of the steel pipes 2 at both ends are adjusted to be consistent, so that the transmission direction of the steel wire rope 6 is kept in the horizontal direction;
[0029] The pan-tilt platform 7 equipped with the non-destructive testing instrument is fixed above the wire rope 6 by the flat head screw 71, and the friction force generated by the flat head screw 71 squeezing the wire rope 6 is used to fix the pan-tilt platform 7 on the wire rope 6. The non-destructive testing instrument is fixedly installed on the pan-tilt platform 7, and the double-rope winch motor 1 is remotely controlled to drive the pan-tilt platform 7 equipped with the non-destructive testing instrument into the cast-in-place beam support. After the pan-tilt platform 7 is driven to the position of the box beam that needs to be inspected, the double-rope winch motor 1 is paused. After the inspection data is collected, the pan-tilt platform 7 equipped with the non-destructive testing instrument is driven by the double-rope winch motor 1 to produce the cast-in-place beam support. After completing the non-destructive testing task, the double-rope winch motor 1 and the steel pipe 2 with the fixed pulley 4 are removed and recycled from the cast-in-place beam support.
