In the present embodiment, as shown in fig. 3, the tension mechanism 200 includes a base 210, two top beams 211 are disposed in parallel on the top of the base 210, and each of the two top beams 211 includes a front section and a rear section; each rear section is provided with a slide rail 212, and the two slide rails 212 are arranged in parallel; a steel bar pulling mechanism 230 is arranged between the two rear sections, and the bottom of the steel bar pulling mechanism 230 is provided with two third sliding chutes matched with the sliding rails; the bottom of the steel bar pulling mechanism 230 is also provided with a second chute 239 for the steel bar to pass through; a power transmission mechanism 240 is connected below the steel bar pulling mechanism 230, and the second power transmission mechanism 240 is used for driving the steel bar pulling mechanism 230 to slide back and forth relative to the base 210; the steel bar pulling mechanism 230 is used for pressing the steel bar passing through the second sliding groove 239 and driving the steel bar to translate towards the rear end.
The reinforcing steel bar passing through the second sliding groove is tightly pressed through the reinforcing steel bar pulling mechanism, the power transmission mechanism drives the reinforcing steel bar pulling mechanism to move forwards, the reinforcing steel bar is loosened when the reinforcing steel bar reaches the movement limit, the power transmission mechanism drives the reinforcing steel bar pulling mechanism to return to the original position, the reinforcing steel bar is tightly pressed again, the actions are repeated, the effect of driving the reinforcing steel bar to horizontally move is achieved, and the straight degree of the reinforcing steel bar can be kept in the reinforcing steel bar pulling process.
In this embodiment, the reinforcing bar pulling mechanism 230 includes a second bottom plate 231, and a third sliding slot is formed at the bottom of the second bottom plate 231. The second bottom plate 31 may serve as a bottom support for the entire rebar pulling mechanism 30. The third sliding groove can be matched with the sliding rail 12, so that the movement of the steel bar pulling mechanism 30 is smoother. Of course, the movement mode such as the pulley can also be adopted, and the selection can be carried out according to the actual requirement.
As a specific implementation form, a second base plate 233 is disposed on the second bottom plate 231, a second sliding groove 239 is disposed on the second base plate 233, and the second sliding groove 239 is disposed in parallel with the sliding rail 212. Through setting up second backing plate 233, and set up second spout 239 on it, can make the reinforcing bar keep inside second spout 239 when the pulling, play limiting displacement, moreover, because the reinforcing bar can rub second bottom plate 231 at the pulling in-process, so increased second backing plate 233, it can be installed on second bottom plate 231 with rivet or bolt mode, after second spout 239 wearing and tearing are serious, can directly just trade second backing plate 233, need not change the bigger second bottom plate 231 of area and volume, can reduce the maintenance cost.
In the embodiment of the present invention, the second base plate 233 is provided with a second cylinder bracket 237 and a second press block bracket 238; the top of the second cylinder bracket 237 is provided with a second cylinder 234; a second pressing block 236 is hinged on the second pressing block bracket 238; the second telescopic rod of the second cylinder 234 faces downwards, the free end of the second telescopic rod is hinged with a second connecting rod 235, and the other end of the second connecting rod 235 is fixedly connected to a second pressing block 236; the second pressing block 236 is used for moving downwards and pressing the reinforcing steel bars under the driving of the second connecting rod 235 when the second telescopic rod moves downwards. The second pressing block 236 may be in a pie shape, and the periphery thereof is a circular surface, during installation, the connecting shaft may not be disposed on the axis of the second pressing block 236, and the pressing of the steel bar is realized by using the eccentric shaft principle, that is, when the telescopic rod of the second cylinder 237 moves downward, the one end of the second connecting rod 235 is driven to move downward, the other end of the second connecting rod 235 drives the second pressing block 236 to rotate, because the second pressing block 236 and the second pressing block bracket 238 are hinged, the second pressing block 236 may rotate, and because the second pressing block 236 does not rotate along the central shaft, when the second pressing block 236 rotates, the bottom thereof may be lower and lower, and when the bottom is lower to a certain degree, the steel bar may be pressed.
In the embodiment of the present invention, a third cylinder bracket is further disposed on the second base plate 233 and behind the pressing block 236, the third cylinder bracket is mounted with the third cylinder 232, and the free end of the third cylinder 232 faces downward and has a groove conforming to the shape of the steel bar.
