[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] As Figures 1 to 4 shown, the present invention provides a roadbed and pavement construction side pile positioning device, including a first base 1. A first vertical frame 2 is fixedly arranged at the top of the first base 1, and a positioning component 3 is further included at the top of the first vertical frame 2;

[0026] The positioning component 3 includes a protective cover 31 fixedly arranged at the top of the first vertical frame 2. A rewinding rotating shaft 32 is rotatably arranged inside the protective cover 31. A torsion spring 33 is fixedly arranged above the outer side of the rewinding rotating shaft 32, and the other end of the torsion spring 33 is fixedly arranged with the protective cover 31. The rewinding rotating shaft 32 rotates inside the protective cover 31, and cooperates with the torsion spring 33 to drive the rewinding rotating shaft 32 to wind up the towing rope 34 to keep it in a taut state. The towing rope 34 is wound around the outer side of the rewinding rotating shaft 32. A second positioning ring 37 is slidably arranged on the outer side of the towing rope 34. A first clamping piece 39 is fixedly arranged on the left side of the second positioning ring 37. A long screw 38 is fixedly arranged on the left side of the first clamping piece 39, and the long screw 38 is slidably arranged with the first vertical frame 2. A second clamping piece 310 is slidably arranged on the outer side of the long screw 38, and the second clamping piece 310 is attached to the outer side of the first vertical frame 2. The long screw 38 can move up and down inside the first vertical frame 2 to control the descent of the second positioning ring 37.

[0027] Specifically, a first positioning ring 36 is fixedly arranged on the outer side of the protective cover 31, and the first positioning ring 36 is slidably arranged with the towing rope 34. The towing rope 34 moves inside the first positioning ring 36, which can achieve the effect of stable towing.

[0028] Further, a first spring 312 is tightly abutted against the left side of the second clamping piece 310, and the first spring 312 is sleeved outside the long screw 38. The other end of the first spring 312 is tightly abutted against a compression nut 311, and the compression nut 311 is helically arranged with the long screw 38. Rotating the compression nut 311 can push the first spring 312 to push the second clamping piece 310 to be positioned in a state outside the first vertical frame 2.

[0029] Furthermore, a limiting ball 35 is fixedly arranged at the other end of the towing rope 34. A clamping ball 7 is fixedly arranged outside the limiting ball 35, and a pull ring 8 is fixedly arranged outside the clamping ball 7. During the winding process of the towing rope 34, it can be positioned under the bottom opening of the second positioning ring 37 through the limiting ball 35.

[0030] It should be noted that a second vertical frame 6 is slidably arranged outside the clamping ball 7. A slider 9 is fixedly arranged at the bottom end of the second vertical frame 6. A second base 4 is slidably arranged outside the slider 9. A positioning pin 5 penetrates through the inside of the second base 4. The clamping ball 7 can be slid into the inside of the second vertical frame 6, thereby positioning the towing rope 34.

[0031] It should be noted that a horizontal shaft 10 penetrates through the inside of the slider 9, and the horizontal shaft 10 is fixedly arranged with the second base 4. A second spring 11 is sleeved outside the horizontal shaft 10, and the second spring 11 is located between the second base 4 and the slider 9. The second spring 11 can push the slider 9 outside the horizontal shaft 10 to move, pushing the upper second vertical frame 6 for towing and tightening the towing rope 34.

[0032] Among them, the towing rope 34 is a prior art and will not be elaborated; at the same time, the present utility model also includes a power source, a controller, a switch, etc., which are not the main technical points of this patent and will not be elaborated.

[0033] Working principle and process:

[0034] The construction workers move the positioning component 3 to the construction road surface. According to the route of the construction of the roadside piles on the road surface, first place the first base 1 at the starting point on the ground, and then tow and place the second base 4 at the end point of the roadside pile construction. Move the towing ring 8, drive the clamping ball 7 and the towing rope 34 to pull out from the outside of the winding shaft 32. After the torsion spring 33 on the outside of the winding shaft 32 rotates and opens, the towing rope 34 can be pulled out of the protective cover 31. Place the clamping ball 7 outside the limiting ball 35 of the towing rope 34 into the vertical groove of the second vertical frame 6 to position the clamping ball 7. Cooperate with the slider 9 at the bottom of the second vertical frame 6 inside the second base 4, and push through the horizontal shaft 10 and the spring two 11 on the outside to tighten the second vertical frame 6 and the towing rope 34 between the first vertical frame 2 and the second vertical frame 6 to maintain the stability of the positioning. At the same time, when the road surface height is not level enough, when the towing rope 34 needs to be moved up to a high point position, the long screw 38 can be pulled to rise along the vertical groove of the first vertical frame 2. Through the elastic pressing state of the spring one 312, it can cooperate with the clip one 39 and the clip two 310 on the outside of the long screw 38 to maintain the stability after the lifting height. After moving to the required height, tighten the pressing nut 311 structure to maintain the stable clamping state of the clip one 39, which is more stable to use. The excess towing rope 34 enters the protective cover 31 through the positioning ring one 36, and is towed and wound by the winding shaft 32 and the torsion spring 33 to store the excess towing rope 34 inside the protective cover 31, and always maintain the tension state of the towing rope 34 to maintain the stability of the positioning.
