[0032] The survey mechanism 1 includes a protective shell 101, a motor and a wireless control device are installed inside the protective shell 101, a survey camera 102 is installed on the side of the protective shell 101, a support groove 103 is opened at the bottom of the protective shell 101, and a support frame 104 is fixedly connected to both sides of the support groove 103.

[0033] The four corners of the bottom of the protective housing 101 are provided with connecting threaded holes 110;

[0034] The clamping mechanism 2 includes a support and protection frame 201, and connecting legs 202 are installed on both sides of the support and protection frame 201. The connecting legs 202 and the connecting threaded holes 110 are cooperated to be penetrated by bolts to fix the support and protection frame 201 to the bottom of the protective shell 101, and the fixing depth of the bolts is determined according to the diameter of the inclined cable, with the goal that both the active roller 106 and the driven roller 205 can be stressed and the active roller 106 and the driven roller 205 do not slip downward;

[0035] Through grooves 203 are provided on both sides of the support and protection frame 201, and an articulated frame 204 is fixedly connected to the inner bottom of the support and protection frame 201, and a rotatable driven roller 205 is installed between the two inner sides of the articulated frame 204;

[0036] The driven roller 205 and the driving roller 106 are of equal length, and grooves are provided in the middle of the driven roller 205 and the driving roller 106. The grooves of the driven roller 205 and the driving roller 106 are clamped on the outer surface of the inclined cable.

[0037] Through the above technical solution, the active roller 106 and the driven roller 205 are arranged to cooperate with each other, so as to apply force from both sides of the inclined cable to fix on the surface of the inclined cable, and the active roller 106 is driven by the motor to rotate, so that the whole device can move on the inclined cable. While the device is moving, the status of the inclined cable is photographed in real time through the survey camera 102, and the photographed image is transmitted to the operator, so as to achieve the effect of convenient survey of the bridge inclined cable;

[0038] When in use, the support and protection frame 201 is first completely disassembled, and the active roller 106 is allowed to contact the inclined cable first, and then the support and protection frame 201 is installed to make the driven roller 205 contact the inclined cable, thereby forming a clamping force.

[0039] Specifically, a protective groove 108 is opened on the side of the protective shell 101 , and the survey camera 102 is installed inside the protective groove 108 .

[0040] Through the above technical solution, the purpose of setting the protective groove 108 is to protect the survey camera 102, so that the survey camera 102 can adjust the observation angle up and down inside the protective groove 108 to avoid collision between the survey camera 102 and the inclined cable.

[0045] Specifically, there are two groups of driven rollers 205 , and the two groups of driven rollers 205 are respectively located on both sides of the active roller 106 .

[0046] Through the above technical solution, two sets of driven rollers 205 and active rollers 106 are provided to cooperate with each other to clamp the inclined cable, thereby effectively improving stability and effectively increasing friction to prevent the entire device from sliding down due to gravity.

[0047] Specifically, the outer surfaces of the active roller 106 and the driven roller 205 are both provided with rubber layers, and the rubber layers can enhance the friction force by deformation.

[0048] Through the above technical solution, the purpose of providing the rubber layer on the outer surface of the active roller 106 and the driven roller 205 is to increase the friction force, so as to make the whole device more stable when moving.

[0049] When in use, the active roller 106 and the driven roller 205 are arranged to cooperate with each other, so that force is applied from both sides of the inclined cable to fix on the surface of the inclined cable, and the active roller 106 is driven by the motor to rotate, so that the entire device can move on the inclined cable. While the device is moving, the status of the inclined cable is photographed in real time through the survey camera 102, and the photographed image is transmitted to the operator, so that the effect of convenient survey of the bridge inclined cable is achieved;
