Description

Technical Field

[0001] The present invention relates to the technical field of anchor cable tension detection, and in particular to an anchor cable tension detection device with a prestress compensation function. Background Art

[0002] The prestressed anchor cable is a commonly used support method for slope support, which applies prestress to the slope through the anchor cable. Applying prestress through the anchor cable can significantly improve the strength of slope support on the one hand, and on the other hand, it can connect the rock and soil mass on the slope surface with the internal rock and soil mass, enhance the integrity of the slope, and avoid the occurrence of sliding bodies. Due to reasons such as the self-deformation of the slope or the relaxation of the steel strand, the prestress of the existing anchor cable may have a large loss, affecting the anchoring quality of the entire project.

[0003] Currently, the technology for stress compensation of prestress-loss anchor cables in the prior art is mainly secondary tensioning. And timely secondary tensioning also consumes a lot of manpower, material resources and time. Moreover, in the actual application of anchor cable tension detection, multiple strands of anchor cables are installed in the preset holes of slope support. When fixing multiple strands of anchorages, the anchor cables are too messy and difficult to perform pressure detection.

However, the present invention may be practiced in other ways than those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0020] Example, according to Figures 1 - 7 , such as Figure 1 As shown, an anchor cable tension detection device with a prestress compensation function provided by an embodiment of the present invention includes an anchor cable limiting mechanism 100. A driving detection mechanism 200 is installed inside the anchor cable limiting mechanism 100. The anchor cable limiting mechanism 100 limits and concentrates the anchor cable and fixes it centrally. A secondary compensation mechanism 300 is also installed inside the anchor cable limiting mechanism 100. The driving detection mechanism 200 and the secondary compensation mechanism 300 are installed together. The anchor cable limiting mechanism 100 can concentrate and fix the anchor cable, and then the driving detection mechanism 200 can pull the anchor cable for tension detection. At the same time, the secondary compensation mechanism 300 can secondarily tighten and fix the anchor cable to achieve the effect of prestress compensation. The anchor cable limiting mechanism 100 includes a device housing 101. Both ends of the device housing 101 are open. A number of evenly distributed mounting grooves 102 are provided on the surface of the device housing 101. A rocker 103 is rotatably installed in each mounting groove 102. A limiting plate 104 is fixedly connected to one end of each rocker 103. The limiting plate 104 is located at one end of the device housing 101. The rocker 103 rotates around the mounting groove 102, and the limiting plate 104 at one end of the rocker 103 will move to one end of the device housing 101 to achieve the effect of limiting and concentrating the anchor cable. The driving detection mechanism 200 includes a first motor 204. A motor seat 205 is fixedly connected to one side of the first motor 204. The motor seat 205 is fixedly connected to the inner wall of the device housing 101 away from the limiting plate 104. The output shaft of the first motor 204 is fixedly connected to a driving gear 212, and the first motor 204 drives the driving gear 212 to rotate.

[0021] Such as Figures 2 - 3As shown, a connecting member 105 is fixedly connected to the other end of each lever 103. A first fixing seat 106 is rotatably installed in each connecting member 105. A limiting sleeve 107 is fixedly connected to the inner side of each first fixing seat 106. The limiting sleeve 107 is located inside the equipment housing 101. Both ends of the limiting sleeve 107 are open. When the limiting sleeve 107 moves, it can drive the lever 103 to rotate around the installation groove 102. A number of uniformly distributed limiting grooves 108 are provided at the edge of one end of the limiting sleeve 107. An installation rod 113 is rotatably installed in each limiting groove 108. A second fixing seat 114 is rotatably installed at one end of each installation rod 113. Each second fixing seat 114 is fixedly connected to the inner wall of the equipment housing 101. A front clamping plate 112 is fixedly connected to the other end of each installation rod 113. Each front clamping plate 112 is located inside the limiting sleeve 107. During the movement of the limiting sleeve 107, the front clamping plate 112 can rotate around the second fixing seat 114, and the front clamping plate 112 will move into the limiting sleeve 107 to realize the preliminary clamping of the cable anchor.

[0022] As Figures 2 - 3 shown, an installation sleeve 109 is rotatably installed at the other end of the limiting sleeve 107. A gear ring 116 is fixedly connected to the edge of one end of the installation sleeve 109. A mating gear 117 is meshed with the outside of each gear ring 116. A rotating shaft 118 is fixedly connected to the center of each mating gear 117. Each rotating shaft 118 is rotatably installed on the inner wall of the equipment housing 101. A fixing member 119 is fixedly connected to one end of each rotating shaft 118. A rear clamping plate 120 is fixedly connected to one end of each fixing member 119. The rotation of the installation sleeve 109 can drive the rear clamping plate 120 to move into the limiting sleeve 107 to fix the cable anchor in the limiting sleeve 107. Each rear clamping plate 120 is located inside the limiting sleeve 107. Four uniformly distributed limiting holes 111 are provided on the surface of the installation sleeve 109. A limiting rod 110 is installed in each limiting hole 111. Each limiting rod 110 is fixedly connected to the inner wall of the equipment housing 101. Four uniformly distributed extending sliding rails 115 are fixedly connected to the edge of one end of the installation sleeve 109. During the movement of the limiting sleeve 107, the rotation of the installation sleeve 109 can be driven by the limitation of the limiting rod 110.

[0023] As Figures 8 - 10As shown, the secondary compensation mechanism 300 includes a second motor 301. The output shaft of the second motor 301 is fixedly connected to an adjustment lead screw 302. The adjustment lead screw 302 is meshed with a movable rod 303. One end of the movable rod 303 is fixedly connected to a fixed plate 313. The second motor 301 drives the adjustment lead screw 302 to rotate, thereby driving the horizontal movement of the movable rod 303. One side of the fixed plate 313 is fixedly connected with four uniformly distributed telescopic rods 314. The telescopic end of each telescopic rod 314 is fixedly connected with a slider 315. During the movement of the side clamping plate 304, the movement of the side clamping plate 304 can be limited through the telescopic rods 314 and the sliders 315. Four uniformly distributed fixed sheet metals 316 are fixedly connected to the surface of the movable rod 303. One end of each fixed sheet metal 316 is rotatably installed with a transmission sheet metal 312. The upper end of each transmission sheet metal 312 is rotatably installed with a lower connecting seat 311. The upper surface of each lower connecting seat 311 is fixedly connected with a side clamping plate 304. One end of the lower surface of each side clamping plate 304 is provided with a chute 310. The slider 315 is installed in the chute 310. The other side of the lower surface of each side clamping plate 304 is fixedly connected with a rubber plate 305. Each side clamping plate 304 is arranged in an installation sleeve 109. One side of the upper surface of each side clamping plate 304 is fixedly connected with an upper connecting seat 309. An upper transmission rod 308 is rotatably installed in each upper connecting seat 309. The upper end of each upper transmission rod 308 is rotatably installed with an installation bracket 306. Limiting blocks 307 are fixedly connected to both sides of each installation bracket 306. Each installation bracket 306 is installed in an extension slide rail 115 through the limiting blocks 307. The horizontal movement of the movable rod 303 can drive the four side clamping plates 304 to expand or concentrate. The cable anchor is clamped and fixed by the centering of the side clamping plates 304.

[0024] As Figures 6 - 7As shown, driven gears 211 are meshed and connected to both sides of the driving gear 212. A driving lead screw 206 is fixedly connected to the center of each driven gear 211. One end of each driving lead screw 206 is meshed and connected to a mating rod 207. One end of each mating rod 207 is fixedly connected to the outer surface of the limiting sleeve 107. When the driving gear 212 rotates and drives the driven gear 211, the driving lead screw 206 is driven to rotate. When the driving lead screw 206 meshes with the mating rod 207, the limiting sleeve 107 can be pushed to move horizontally. A sliding plate 208 is meshed and connected to each driving lead screw 206. A connecting sheet metal 209 is fixedly connected to the lower surface of the sliding plate 208. Side sliders 203 are fixedly connected to both ends of the connecting sheet metal 209. The side sliders 203 are installed in the side concave holes 121. A motor bracket 210 is fixedly connected to one side of the connecting sheet metal 209. Side connecting rods 201 are fixedly connected to the outer sides of both side sliders 203. One end of each side connecting rod 201 is fixedly connected to a backing plate 202. The driving lead screw 206 can drive the side sliders 203 to move horizontally along the side concave holes 121. Since the threads of the mating rod 207 and the sliding plate 208 are arranged in opposite directions, the limiting sleeve 107 and the side connecting rod 201 move in opposite directions, achieving the effect of pulling the anchor cable to move.

[0025] The working principle of the present invention is as follows: Place the device on one side of the cable anchor and align the cable anchor with one end of the outer shell 101, then start the first motor 204. By driving the lead screw 206 and the mating rod 207, the limit sleeve 107 is pushed to move horizontally. The movement of the limit sleeve 107 can drive the lever 103 to rotate around the mounting groove 102 through the first fixed seat 106. The limit plate 104 at one end of the lever 103 can limit the messy cable anchor, making it centered and inserted into the limit sleeve 107. At the same time, the mounting rod 113 rotates around the second fixed seat 114, so that the front clamping plate 112 can move into the limit sleeve 107 to achieve the preliminary fixation of the cable anchor. At the same time, the mounting sleeve 109 is limited by the limit rod 110 and rotates within the limit sleeve 107. The mounting sleeve 109 can drive the rotating shaft 118 to rotate through the gear ring 116 and the mating gear 117. The rear clamping plate 120 at one end of the rotating shaft 118 is used to fixedly clamp the cable anchor. And because the threads of the mating rod 207 and the slide plate 208 are set in opposite directions, when the limit sleeve 107 fixes the cable anchor, the drive lead screw 206 will drive the side connecting rod 201 and the backing plate 202 to closely adhere to the surface of the supporting side plate and move in the opposite direction of the cable anchor. On the one hand, it can conduct a tensile test on the cable anchor, and on the other hand, it can straighten the cable anchor in the center. During the test, the second motor 301 can also be started to drive the movable rod 303 to move horizontally through the adjusting lead screw 302. The movement of the movable rod 303 is transmitted through the transmission sheet metal 312 and the upper transmission rod 308, and then drives the side clamping plates 304 to rotate around the mounting bracket 306, realizing the centering or expansion of the four side clamping plates 304. The rubber plate 305 on the lower surface of the side clamping plates 304 is used to clamp and fix the cable anchor, and the side clamping plates 304 will drive the cable anchor to move along with the side slider 203 to realize the secondary tensioning of the cable anchor.

[0026] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
