Description

Technical Field

[0001] This utility model relates to the field of photovoltaic steel pile construction technology, and in particular to an auxiliary device for controlling the horizontal angle of photovoltaic steel piles during construction. Background Technology

[0002] Due to the rapid development of photovoltaic technology, fixed supports have been upgraded to tracking supports, and now most photovoltaic systems use tracking supports. Tracking supports can greatly increase power generation and significantly save on construction costs. However, because the spacing between each group of steel piles in the tracking support is relatively large, it is difficult to control and detect when the horizontal direction and torsional angle of the steel piles deviate during construction. Traditional rope tensioners cause serious damage to the wire rope and have a low usage frequency; excessive tension with traditional rope tensioners can cause the wire rope to break, while insufficient tension can cause the wire rope to sag and swing excessively in windy weather; moreover, traditional rope tensioners are not easy to meet the control accuracy requirements, which are all problems and drawbacks.

[0003] Therefore, there is an urgent need for an auxiliary device to control the horizontal angle of photovoltaic steel piles during construction, which can improve the horizontal accuracy of the rope. Utility Model Content

[0004] This utility model provides an auxiliary device for controlling the horizontal angle of photovoltaic steel piles during construction, in order to solve the problem that existing traditional rope tensioners are difficult to control the horizontal accuracy of the rope.

[0005] To overcome the above-mentioned technical problems, according to an embodiment of the present invention, an auxiliary device for controlling the horizontal angle of photovoltaic steel piles during construction is provided, comprising:

[0006] A support frame; the support frame is arranged horizontally and has a vertical reference plane on one side. Two reference rods are provided on the support frame. The two reference rods are parallel and the plane on which they are located is parallel to the vertical reference plane. At least one alignment rod is provided on each reference rod. The alignment rod is perpendicular to the vertical reference plane and is elastic.

[0007] A fixing device is installed on the support frame; the fixing device includes a positioning rod, the positioning rod is perpendicular to the vertical reference plane, and the free end of the positioning rod is provided with a U-shaped groove;

[0008] A tightening device is provided on the support frame; the tightening device includes a pulley and a cable-collecting wheel that are rotatably mounted on the support frame, the pulley and the cable-collecting wheel cooperate with each other and are both located on the side away from the vertical reference plane; the pulley is located between the two reference rods; a crank is provided on the cable-collecting wheel.

[0009] In some embodiments, the number of the benchmarks is two, with one benchmark provided on each of the reference rods.

[0010] In some embodiments, a gravity ball is provided at the free end of the benchmark.

[0011] In some embodiments, a clamping device is provided in the U-shaped slot. The clamping device includes a telescopic rod that is telescopically disposed in the U-shaped slot. A top plate is provided at the free end of the telescopic rod. A spring is sleeved on the telescopic rod. The spring abuts against the top plate to provide the top plate with an elastic force toward the steel pile.

[0012] In some embodiments, a gasket is fixed to one end of the top plate.

[0013] In some embodiments, the support frame is provided with a stop hole, and a stop rod can be inserted into the stop hole to stop the crank handle.

[0014] In some embodiments, the number of stop holes is multiple, and they are spaced apart.

[0015] In some embodiments, a through hole is provided on the base plate of the fixed pulley for the rope to pass through.

[0016] The technical solutions provided by the embodiments of this utility model may include the following beneficial effects:

[0017] This invention ensures the reference rod is vertical by attaching it to the edges of the two flanges of the H-beam of the steel pile with a vertical reference plane. Then, a positioning rod is attached to one flange of the H-beam of the steel pile, thus ensuring the horizontal angle of the support frame. The rope is tightened by a tightening device. The reference rod has a benchmark rod facing the direction of rope extension. The benchmark rod is elastic, causing the free end of the benchmark rod to sink. The angle of the rope sinking due to gravity is compared with the benchmark rod, and the rope is stretched until the sinking angle is less than that of the benchmark rod, ensuring the rope is horizontal and improving accuracy.

[0026] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0028] like Figure 1-3 As shown, this utility model provides an auxiliary device for controlling the horizontal angle of photovoltaic steel piles during construction, including a support frame 1, a fixing device 4 fixedly installed on the support frame 1, and a tightening device 5.

[0029] Specifically, the support frame 1 is horizontally positioned and has a vertical reference surface 101 on one side. When in use, the vertical reference surface 101 is first pressed against the steel pile to ensure that the basic angle of the support frame 1 is in the vertical plane. Two reference rods 2 are welded onto the support frame 1. The two reference rods 2 are parallel, and their planes are parallel to the vertical reference surface 101, so that when the vertical reference surface 101 of the support frame 1 is in the vertical plane, the two reference rods 2 also extend forward in the vertical plane. At least one alignment rod 3 is fixed on each reference rod 2. In this specific embodiment, there are two alignment rods 3, with one alignment rod 3 fixed on each reference rod 2. The alignment rods 3 are perpendicular to the vertical reference surface 101 and are elastic. After the support frame 1 is fixed on the steel pile, the benchmark 3 extends towards the side where the rope extends. Since the benchmark 3 is elastic and the free end of the benchmark 3 is fixed with a gravity ball 6, the free end of the benchmark 3 will sink, similar to the sinking of the rope. A reference is made for the sinking angle of the rope. The maximum sinking angle of the rope should not exceed the sinking angle of the benchmark 3.

[0030] To fix the support frame 1 to the steel pile, a fixing device 4 is welded onto the support frame 1. The fixing device 4 includes a positioning rod 401, which is perpendicular to the vertical reference plane 101. The free end of the positioning rod 401 is formed with a U-shaped groove 402. In use, the U-shaped groove 402 is clamped onto one flange of the H-beam of the steel pile, so that the positioning rod 401 is close to one flange of the H-beam. To temporarily fix the fixing device 4 to the H-beam before the rope is tightened, a clamping device 7 is installed in the U-shaped groove 402. The clamping device 7 includes a telescopic rod 701 that is telescopically installed in the U-shaped groove 402. The free end of the telescopic rod 701 is formed with a top plate 702. A spring 703 is sleeved on the telescopic rod 701. The spring 703 abuts against the top plate 702 to provide elastic force to the top plate 702 toward the steel pile. In use, first pull the telescopic rod 701 away from the U-shaped slot 402 to compress the spring 703, locking the U-shaped slot 402 onto one flange of the H-beam. Then release the telescopic rod 701, allowing the top plate 702 to press against one flange of the H-beam. A rubber washer 704 is fixed to one end of the top plate 702. The friction is increased when the top plate 702 presses against the washer 704 against one flange of the H-beam. For specific operation, a nut can be threaded onto the other end of the telescopic rod 701 to prevent it from easily coming loose.

[0031] In this specific embodiment, the function of the tightening device 5 is to tighten the rope. In use, one of the auxiliary devices for controlling the horizontal angle of photovoltaic steel piles (as described in this application) is installed at the first and last piles of each row of piles. The two tightening devices 5 on the first and last piles are connected to a rope, and the rope is tightened from both ends to straighten it. The middle steel pile can then be installed along this rope, ensuring all steel piles are on the same straight line. Specifically, the tightening device 5 includes a pulley 501 and a cable-collecting wheel 502 rotatably mounted on the support frame 1. The pulley 501 and cable-collecting wheel 502 cooperate with each other and are both installed on the side away from the vertical reference plane 101. A crank 503 is installed on the cable-collecting wheel 502; the rope is tightened by rotating the crank 503. The pulley 501 is located between two reference rods 2. A through hole 506 is provided on the base plate that fixes the pulley 501 for passing a rope through. When in use, the rope passes through the through hole 506, goes around the pulley 501, and connects to the cable tray 502.

[0032] In order to make the cable pulley 502 rotate to tighten and fix the rope, the support frame 1 is provided with multiple stop holes 504. The multiple stop holes 504 are spaced apart, and the stop rod 505 can be inserted into the stop hole 504 to stop the crank handle 503.
