The partition plate 24 and the convex plate 25 are fixedly connected with a limiting rod 211, the limiting rod 211 penetrates through and movably connects with the nut block 26. One side of the partition plate 24 is fixedly connected with a fixed clamping block 28. The tensioning assembly 2 further comprises a conical clamping piece 29, the conical clamping piece 29 can be inserted into the inside of the mounting block 23.
[0030] In specific implementation: after the anchor cable passes through the mounting block 23, the conical clamping piece 29 is inserted around the anchor cable, then the anti-skid rotating ring 210 is screwed to drive the bidirectional screw rod 217 to rotate, the bidirectional screw rod 217 rotates and drives the nut block 26 to move linearly under the limitation of the limiting rod 211, the nut block 26 drives the movable clamping block 27 to move close to the fixed clamping block 28 to clamp and fix all the conical clamping pieces 29, then the through hydraulic jack 213 is started to drive the outer sleeve anchor 214 to move outward, when the inner wall of the conical inner recess hole 215 of the outer sleeve anchor 214 contacts the conical clamping piece 29, since the conical clamping piece 29 is conical in shape and the inside of the conical inner recess hole 215 is also conical in shape, the conical inner recess hole 215 will exert a pressure on the conical clamping piece 29 to tighten it inward and fix the anchor cable to stretch outward.
[0031] Reference Figures 1 to 4 In one aspect of the embodiment, the tensioning assembly 2 further comprises a through hydraulic jack 213, one end of the through hydraulic jack 213 is fixedly connected with the inside of the bottom plate 1. The tensioning assembly 2 further comprises an outer sleeve anchor 214, the inside of the outer sleeve anchor 214 is provided with a conical inner recess hole 215, the bottom of the outer sleeve anchor 214 is fixedly connected with a positioning block 216, the positioning block 216 can be inserted into one end of the inside of the through hydraulic jack 213.
[0032] In specific implementation: first, the outer sleeve anchor 214 is inserted into one end of the through hydraulic jack 213 through the positioning block 216, then the through hydraulic jack 213 is sleeved on one end of the anchor cable to make the anchor cable pass through, when the anchor cable passes through, it passes through the conical inner recess hole 215 to be conveniently preliminarily constrained and fixed.
[0033] All the electrical equipment in this scheme is powered by external power supply.
[0034] Working principle: Firstly, the outer sleeve anchor 214 is inserted into one end of the through hydraulic jack 213 by the positioning block 216. Then, the through hydraulic jack 213 is sleeved on one end of the anchor cable, and the anchor cable passes through it. When the anchor cable passes through, it will pass out through the conical inner recess hole 215, thereby achieving preliminary constraint and fixation of the anchor cable. Next, after the anchor cable passes through the installation block 23, the conical clamping piece 29 is inserted around the periphery of the anchor cable. Then, the anti-skid swivel ring 210 is twisted, thereby driving the bidirectional screw rod 217 to rotate. The bidirectional screw rod 217 rotates under the limitation of the limiting rod 211, which promotes the linear motion of the nut block 26. The nut block 26 then drives the movable clamping block 27 to approach the fixed clamping block 28, thereby clamping and fixing all the conical clamping pieces 29. Finally, the through hydraulic jack 213 is started, driving the outer sleeve anchor 214 to move outward. When the inner wall of the conical inner recess hole 215 of the outer sleeve anchor 214 contacts the conical clamping piece 29, since the conical clamping piece 29 is conical and the inner shape of the conical inner recess hole 215 is also conical, the conical inner recess hole 215 will exert a pressure on the conical clamping piece 29 to its inside, thereby compressing and fixing the anchor cable and making it stretch outward.
