[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Reference Figure 1-10 A steel strand rapid reinforcement machine comprises a chassis 1, wherein a plurality of squeezing rollers 2 are rotatably mounted inside the chassis 1, two adjacent squeezing rollers 2 are arranged as a group, and four squeezing rollers 2 at the same level quickly reinforce one steel strand, and a variable pitch mechanism is provided between the plurality of squeezing rollers 2; when the device quickly reinforces the steel strand, the four squeezing rollers 2 at the same level quickly transport a single steel strand, and at the same time, in order to adapt to corrugated tubes with different spacings, the squeezing rollers 2 at different levels can be raised and lowered by the variable pitch mechanism to change the spacing between them. Because in actual production, the spacing between multiple corrugated tubes is equal, so the device only adjusts the squeezing rollers 2 at different heights at equal distances.

[0031] As the preferred technical solution of this embodiment, a plurality of connecting shafts 3 are rotatably installed inside the chassis 1, and a plurality of the squeezing rollers 2 are slidably installed on the connecting shafts 3. A plurality of slide grooves 5 are opened on the side walls of the connecting shafts 3, and the squeezing rollers 2 are slidably adapted to the slide grooves 5; this device slidably connects the connecting shaft 3 and the squeezing roller 2 together through the slide grooves 5, so that while the connecting shaft 3 drives the squeezing roller 2 to rotate, the squeezing roller 2 can change its height under the action of the pitch changing mechanism.

[0032] As the preferred technical solution of this embodiment, the pitch changing mechanism includes multiple adjustment plates 6, which are slidably installed inside the chassis 1. Three movable grooves 7 are opened on one side of the multiple adjustment plates 6, and connecting columns 8 are slidably installed inside the three movable grooves 7. A connecting frame 9 is fixedly installed at one end of the connecting column 8, and two connecting rings 10 are fixedly installed on the connecting frame 9. The extrusion roller 2 is rotatably adapted to the two connecting rings 10; when the present device adjusts the spacing between the extrusion rollers 2, the position of the connecting column 8 inside the movable groove 7 is changed by moving the adjustment plate 6, thereby changing the height of the connecting column 8, and then changing the corresponding height of the extrusion roller 2. Three movable grooves 7 are provided on the adjustment plate 6 in the present device, wherein the movable groove 7 in the middle position is a horizontal transverse groove, and the other two movable grooves 7 are oblique grooves, and are symmetrically arranged with the middle movable groove 7 as the symmetry line, so that the spacing between the extrusion rollers 2 at both ends and the middle extrusion roller 2 always remains adjustable and equal.

[0033] As a preferred technical solution of this embodiment, a driving groove 11 is opened on one side of the plurality of adjustment plates 6 away from the movable groove 7, a driving rod 12 is provided inside the driving groove 11, and a connecting block 13 is fixedly connected between the driving rods 12 on the two adjustment plates 6 on the same side, and a slide rail 14 is fixedly installed on both sides of the inner wall of the chassis 1, and the two connecting blocks 13 are respectively slidably installed inside the two slide rails 14, and a ball screw 15 is rotatably installed inside the two slide rails 14, and the two ball screws 15 are respectively threadedly connected to the two connecting blocks 13, and the two ball screws 15 are respectively threadedly connected to the two connecting blocks 13. A transmission mechanism is provided between them; when the device adjusts the squeezing rollers 2, since four squeezing rollers 2 at the same horizontal height are used to reinforce one steel strand, the device needs to make the four squeezing rollers 2 at the same horizontal height rise and fall synchronously. First, the adjustment plate 6 drives the squeezing rollers 2 at different heights on the same connecting shaft 3 to rise and fall, and then the two adjustment plates 6 on the same side are driven to move simultaneously through the connecting block 13, the driving groove 11 and the driving rod 12. Finally, the transmission mechanism drives the four adjustment plates 6 on both sides to move synchronously, and finally the squeezing rollers 2 at different positions at the same horizontal height are lifted and lowered in the same manner.

[0034] As the preferred technical solution of this embodiment, the transmission mechanism includes two pulleys 16 and a transmission belt 17. The two pulleys 16 are rotatably installed at the bottom of the chassis 1. The transmission belt 17 is sleeved on the two pulleys 16. The two ball screws 15 are fixedly connected to the two pulleys 16 respectively; when one ball screw 15 rotates, it drives the pulley 16 to rotate, and drives the other ball screw 15 to rotate through the transmission belt 17, thereby realizing the synchronous rotation of the two ball screws 15.

[0035] As a preferred technical solution of this embodiment, a rotating handle 18 is rotatably installed on the top of the chassis 1, and the rotating handle 18 is fixedly connected to one of the ball screws 15; the ball screw 15 is driven to rotate by the rotation of the rotating handle 18.

[0036] As the preferred technical solution of this embodiment, a first gear 19 is fixedly installed on each of the four connecting shafts 3, and the first gears 19 on two adjacent connecting shafts 3 are meshed with each other. A second gear 20 is provided between two first gears 19 that are farther apart, and the second gear 20 is meshed with the two adjacent first gears 19. A motor 21 is fixedly installed on the top of the chassis 1, and the output end of the motor 21 is fixedly connected to the second gear 20. When the device is in use, the second gear 20 is driven to rotate by the motor 21, and the rotation of the second gear 20 drives the two adjacent first gears 19 to rotate. The two rotating first gears 19 drive the adjacent first gears 19 to rotate, so that the two adjacent extrusion rollers 2 rotate in opposite directions to transmit the steel strand and realize the reinforcement work of the steel strand.

[0037] As the preferred technical scheme of the embodiment, a plurality of guide pipes 22 are slidingly installed on the two side walls of the case 1, and the guide pipes 22 at the same horizontal level are fixedly connected with the connecting frame 9 through the connecting rod 23. The guide pipe 22 and the connecting frame 9 are fixedly connected through the connecting rod 23, and since the connecting frame 9 is at the same horizontal level with the extrusion roller 2, the guide pipe 22 is kept at the same horizontal level with the extrusion roller 2.

[0038] As the preferred technical scheme of the embodiment, the support frame 24 is fixedly installed on the top of the case 1, the telescopic rod 25 is fixedly installed on one side of the support frame 24, the telescopic rod 25 is right above the guide pipe 22, and the cutting machine 26 is fixedly installed on the bottom end of the telescopic rod 25. After the steel strand is laid, the cutting machine 26 is pulled down to cut the steel strand on the guide pipe 22, so that manual cutting is avoided and the work efficiency is improved.
