The upper support 101 and the lower support 102 each comprise two halves that are connected by a tightening nut 122 and a latch 123, which facilitates the installation and removal of the cable detecting device on the cable 600.
As shown in fig. 1 to 5 and 9 to 11, the locking and adjusting unit includes two first traveling assemblies 201 symmetrically mounted on the upper support 101, two second traveling assemblies 202 symmetrically mounted on the lower support 102, a cylinder assembly for adjusting a distance between the two first traveling assemblies, and an adjusting assembly for adjusting positions of the two second traveling assemblies. Under the driving of the braking unit, the first traveling assembly 201 and the second traveling assembly 202 can move along the length direction of the steel cable 600, so that the movement of the whole steel cable detection device along the steel cable is realized.
The cylinder assembly includes a cylinder 203 installed in the sliding groove one 105, a solenoid valve 205 connected to the cylinder 203 through a pipe 204, an air tank 206 connected to the solenoid valve 205 through a pipe 204, and an air pump 207 connected to the air tank 206 through a pipe 204. The solenoid valve 205, the air tank 206, and the air pump 207 are all mounted on the fixing frame 120. The number of the cylinder assemblies is two, and the cylinder assemblies are respectively arranged corresponding to the first two walking assemblies 201. The two cylinder assemblies are used for adjusting the distance between the two first walking assemblies 201, so that the steel cable detection device is suitable for detecting steel cables with different sizes and is wide in application range. And the electromagnetic valve 205 is used for controlling the on-off of the pipeline 204. And the air pump 207 is used for driving the air in the air storage tank 206 to enter the air cylinder 203 and providing an air source for the movement of the air cylinder 203.
The adjusting assembly comprises an adjusting rod 208, the upper end of which is rotatably connected with the upper end of the lower supporting member 102, and the lower end of which is provided with an auxiliary wheel assembly, a pull rod 209 connected between the adjusting rod 208 and a main wheel bracket 213 of the second walking assembly 202, a first spring 210 connected between the main wheel bracket 213 of the second walking assembly 202 and the lower supporting member 102, and a second spring 211 connected between the adjusting rod 208 and a first bracket 106 on the lower supporting member 102. One end of the first spring 210 is connected with the main wheel bracket 213 of the second traveling assembly 202, and the other end is connected with the second sliding groove 107 through a fixed plate. The two adjusting components are symmetrically arranged, and one adjusting component is respectively arranged below the two second walking components 202. The two adjusting components can adjust the distance between the two second walking components 202 to be suitable for steel cables with different sizes or steel cables with uneven thicknesses, and the two second walking components 202 can clamp the steel cable 600 at any time. When the diameter of a steel cable which needs to pass through the two second traveling assemblies 202 or the diameter of a steel cable which passes through the two second traveling assemblies 202 needs to be increased, under the action of external force, the adjusting rod 303 and the adjusting rod bracket 116 rotate relatively through the pivot rod 219, the lower end of the adjusting rod 303 moves downwards, the included angle between the adjusting rod 303 and the lower supporting member 102 is increased, and the adjusting rod 303 drives the second traveling assemblies 202 to move along the radial direction of the lower supporting member 102 through the pull rod 209, namely, the adjusting rod 303 slides outwards in the sliding groove 107. In this process, both spring one 210 and spring two 211 are under tension. The elastic force of the first springs 210 respectively provides a force to the second traveling assemblies 202, which is directed toward the center of the lower support 202, so that the two traveling assemblies 202 clamp the cable 600. The two springs 211 will respectively apply a downward force to the two adjustment rods 208, so that both secondary wheel assemblies 218 can tightly abut against the cable 600, further clamping the cable 600. After the steel cable is drawn out from between the two second traveling assemblies 202 or the size of the steel cable clamped between the two second traveling assemblies 202 is reduced, under the elastic force of the first spring 210 and the second spring 211, the distance between the two second traveling assemblies 202 can be adjusted in a self-adaptive manner according to the size of the steel cable clamped between the two second traveling assemblies 202. The first spring 210 and the second spring 211 can enable wheels in the auxiliary wheel assembly and the second traveling assembly to be located on the same straight line, and the wheels can clamp the steel cable together. By arranging the adjusting assembly, the distance between the two second walking assemblies 202 can be adjusted according to the size of the steel cable, the two second walking assemblies can be ensured to clamp the steel cable constantly, the stability of the steel cable detection device in moving detection along the steel cable is ensured, and meanwhile, the application range of the steel cable detection device is enlarged.
The first walking assembly 201 and the second walking assembly 202 both comprise main wheels 212 and main wheel brackets 213. The main wheel 212 is mounted on a main wheel carrier 213 via a main wheel axle 214. One end of the main wheel shaft 214 passes through the main wheel bracket 213 and is connected with a universal joint 215. And a main wheel shaft adjusting hole is formed in the main wheel bracket. In the first traveling assembly 201, one end of a main wheel shaft 214 passes through a main wheel bracket 213 and is connected with a first universal joint, one end of the first universal joint is connected with the main wheel shaft 214, and the other end of the first universal joint is connected with a gear ten through a transmission shaft eight 216. The main wheel bracket 213 is slidably engaged with the first sliding groove 105 through a guide rail and a sliding block. In the second traveling assembly 202, one end of a main wheel shaft 214 passes through a main wheel bracket 213 and then is connected with a second universal joint, one end of the second universal joint is connected with the main wheel shaft 214, and the other end of the second universal joint is connected with a nineteen gear through a transmission shaft nine 217. The main wheel bracket 213 is in sliding fit with the second sliding groove 107 through the guide rail and the sliding block. By arranging the main wheel shaft adjusting holes, and adopting the universal joint I to connect the main wheel shaft 214 and the transmission shaft eight in the walking assembly I, and adopting the universal joint II to connect the main wheel shaft 214 and the transmission shaft nine in the walking assembly II, the main wheel shaft can be adaptively adjusted in the arc-shaped main wheel shaft adjusting holes in the steel cable self-rotation process of the steel cable detection device, so that the main wheels in the two walking assemblies I can rotate along with the steel cable and can be kept in close contact with the steel cable all the time, and the self-rotation of the steel cable detection device can not influence the normal work of the gear transmission assembly I due to the arrangement of the universal joint. The first walking assembly and the second walking assembly move in the same direction and can ascend or descend along the length direction of the steel cable at the same time. The movement direction of the whole detection device can be adjusted by controlling the rotation directions of the first motor and the second motor and controlling the rotation directions of the worm and gear structures and the gears.
As shown in fig. 9-11 and 13, the brake unit includes a first worm gear structure, a second worm gear structure, a first motor 301 for driving the first worm gear structure to operate, and a second motor 302 for driving the second worm gear structure to operate.
