Description

Technical Field

[0001] This invention relates to the field of photovoltaic assembly technology, and in particular to a wire rope tightening device. Background Technology

[0002] Since tracking technology can significantly improve the power generation efficiency of solar cell modules per unit area, the power generation obtained by using tracking for a solar power plant in the same area is much higher than that obtained by using fixed installation, and it can significantly reduce the cost of solar power generation.

[0003] The applicant proposes a rope drive structure and a solar tracker (CN109164835A), including a drive wheel, a driven wheel, a main drive rope, and multiple tracking units. The main drive rope is connected end to end, with one end sleeved on the drive wheel and the other end sleeved on the driven wheel. Multiple tracking units are spaced apart along the length of the main drive rope. A rotating component is hinged to a mounting bracket. One end of a first branch rope is connected to the rotating component, and the other end is connected to the main drive rope. The first branch rope can drive the rotating component to rotate when the drive wheel rotates.

[0004] When installing the above-mentioned rope transmission structure on site, one end of the first branch rope needs to be connected to the main transmission rope. When connecting the first branch rope and the main transmission rope, the first branch rope needs to be tightened to avoid the risk of the first branch rope falling off due to loosening during the transmission process. The existing tensioning device has the following problems: (1) The existing tensioning device is not a special equipment and cannot be installed on the main transmission rope; for example, if it cannot be installed on the main transmission rope, it is difficult to ensure that the first branch rope and the main transmission rope are set in parallel and close together; that is, there will be a certain angle between the first branch rope and the main transmission rope; in this way, even if the first branch rope is tightened, the first branch rope will still loosen after the connection is completed and then released. (2) The existing tensioning device has a complicated installation structure, which makes it difficult to meet the needs of rapid assembly on the construction site and affects the assembly efficiency.

[0005] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a wire rope tightening device to solve the above problems. Summary of the Invention

The first pin 123 is pinned in the first pin groove 113 and can rotate a certain angle in the first pin groove 113 (the rotation angle depends on the opening size of the first pin groove 113).

[0027] like Figure 2 As shown, in an exemplary embodiment of the present invention, the top of the first base 11 is further provided with a first compression spring mounting groove 114, in which a vertically arranged first compression spring 14 is provided. One end of the first compression spring 14 abuts against the first base 11, and the other end of the first compression spring 14 abuts against the first pressure cover 12.

[0028] like Figure 3 As shown, in an exemplary embodiment of the present invention, the thin steel wire rope clamping assembly 2 is composed of a second base 21 and a second pressure cap 22 hinged together; the top of the second base 21 is provided with a second lower pressure groove 211 on the side away from the hinge side, and the bottom of the second pressure cap 22 is provided with a second upper pressure groove 221 on the side away from the hinge side. The second upper pressure groove 221 and the second lower pressure groove 211 are arranged vertically and vertically and are used to clamp the thin steel wire rope 200; the second base 21 is provided with a second screw hole 212, and the second pressure cap 22 is provided with a second through hole 222 (waist hole). The second through hole 222 and the second screw hole 212 are arranged vertically and vertically; it also includes a second bolt 23, which passes through the second through hole 222 and is threadedly connected to the second screw hole 212.

[0029] like Figure 3As shown, in an exemplary embodiment of the present invention, the second base 21 has a second pin groove 213 with an inverted Ω-shaped cross section on the top hinge side, and the second pressure cover 22 has a second pin 223 with an inverted Ω-shaped cross section on the bottom hinge side. The second pin 223 is pinned into the second pin groove 213 and can rotate a certain angle in the second pin groove 213 (the rotation angle depends on the opening size of the second pin groove 213).

[0030] like Figure 3 As shown, in an exemplary embodiment of the present invention, the top of the second base 21 is further provided with a second compression spring mounting groove 214, in which a vertically arranged second compression spring 24 is provided. One end of the second compression spring 24 abuts against the second base 21, and the other end of the second compression spring 24 abuts against the second pressure cover 22.

[0031] like Figure 1 As shown, in an exemplary embodiment of the present invention, the tightening assembly 3 is composed of a screw 31 and a nut 32. One end of the screw 31 is fixedly connected to the second base 21, and the other end of the screw 31 passes through the first base 11 and is threadedly connected to the nut 32.

[0032] like Figure 2 As shown, in an exemplary embodiment of the present invention, the screw 31 is a flat screw structure, which serves as a guide to prevent the tightening device from rotating. The first base 11 is provided with a screw through hole 115 that matches the shape of the screw 31.

The first washer assembly 15 and the second washer assembly 25 have the same structure and both include an upper washer 4 and a lower washer 5. The bottom surface of the upper washer 4 is convex, and the top surface of the lower washer 5 is concave. The upper washer 4 and the lower washer 5 are fitted together vertically. By setting this structure, when the angle between the first base 11 and the first pressure cap 12 (the second base 21 and the second pressure cap 22) changes, the angle between the bottom surface of the upper washer 4 and the top surface of the lower washer 5 will adaptively adjust to ensure that the contact surfaces of the upper washer 4 and the lower washer 5 are always in contact, thereby ensuring the clamping effect.

[0034] In use, firstly, the coarse wire rope clamping structure formed by the first upper pressure groove 121 and the first lower pressure groove 111 is clamped onto the coarse wire rope 100. Then, the first bolt 13 is tightened with a wrench to clamp and fix the coarse wire rope clamping assembly 1 onto the coarse wire rope 100. It should be noted that in the non-assembled state, the first base 11 and the first pressure cover 12 are in a separated (open) state under the action of the first compression spring 14. This state facilitates the coarse wire rope clamping assembly 1 to be sleeved onto the coarse wire rope 100, which is convenient for quick on-site assembly.

[0035] Next, the wire rope clamping structure formed by the second upper pressure groove 221 and the second lower pressure groove 211 is clamped onto the wire rope 200. Then, the second bolt 23 is tightened with a wrench so that the wire rope clamping assembly 2 is clamped and fixed onto the wire rope 200.

[0036] Finally, tighten the nut 32 with a wrench so that the thin wire rope clamping assembly 2 is close to the thick wire rope clamping assembly 1, thereby realizing the tensioning function of the thin wire rope 200 in a parallel and close state with the thick wire rope 100.

[0037] Therefore, the present invention has the following advantages: This invention provides a wire rope tightening device, which clamps and fixes a thick wire rope using a thick wire rope clamping assembly and a thin wire rope clamping assembly. The thick and thin wire rope clamping assemblies are arranged at intervals along the rope's extension direction and connected by a tensioning assembly. This wire rope tightening device features a dedicated tensioning structure based on the design for fixing the thick wire rope. It can meet the tensioning function when the thick and thin wire ropes are set in parallel and close together, and will not cause an angle problem between the thin and thick wire ropes due to its own structure. In addition, its structure is simple and easy to assemble, which can meet the needs of rapid assembly on construction sites and can significantly improve on-site assembly efficiency.

[0038] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention.
