Description

Technical Field

[0001] The utility model relates to the technical field of flexible photovoltaic component installation, in particular to a cable traction device for installing a flexible photovoltaic component. Background Art

[0002] See also Figure 1 、 2 This is a commonly used cable traction device structure for installing flexible photovoltaic modules. The traction device includes a traction column 10, a ground anchor 20, and a pull rod 30. The traction column 10 is installed on the concrete foundation via anchor threads. Two pull rods 30 are connected to the ground anchor 20 at one end and to the traction column 10 via nuts 31 at the other end after passing through the cross bar 12. The steel wire rope 40 used to install the photovoltaic module is connected to the cross bar 12 on the traction column 10. Since the steel wire rope 40 will be stretched after the photovoltaic module is installed, and will also be stretched during later use, causing the photovoltaic module to deflect downward, the steel wire rope 40 needs to be tensioned when the deflection exceeds the standard. Currently, when tensioning the steel wire rope, the steel cable of the winch equipment is connected to the steel wire rope to tension the steel wire rope. The disadvantage is that when the wire rope is tensioned, the winch needs to be installed and fixed first, and then the steel cable of the winch equipment is connected to the wire rope for traction and tensioning. After traction, the rope buckle needs to be reinstalled on the wire rope, which is a relatively complicated operation. Utility Model Content

[0003] The purpose of the utility model is to provide a flexible photovoltaic module installation cable traction device, which does not require additional auxiliary equipment when tensioning the wire rope, and is simpler to operate.

[0004] To achieve the above-mentioned purpose, the utility model provides a flexible photovoltaic module installation cable traction device, including a traction column, the traction column including a vertical rod and a horizontal rod fixed to the vertical rod, the vertical rod including an upper and lower part, and the upper and lower parts of the vertical rod are hinged by a hinge structure.

[0005] The hinge structure includes two first ear plates and one second ear plate, which are respectively installed on the upper and lower parts of the vertical rod, and the second ear plate is installed between the two first ear plates. The first ear plate and the second ear plate are hinged by a pin shaft.

[0006] The first ear plate and the second ear plate are provided with arc angles only on the same side.

[0007] The two first ear plates and one second ear plate are respectively arranged on the connecting section. The vertical rod is a tubular structure. The two connecting sections are respectively inserted into the upper and lower parts of the vertical rod and are respectively fixed to the upper and lower parts of the vertical rod.

[0008] The upper part of the vertical rod is also fixed with a baffle, which extends downward to the lower part of the vertical rod.

[0009] A positioning bolt is screwed on one side of the lower portion of the vertical rod on the baffle.

[0010] A nut sleeve is installed on one side of the lower part of the vertical rod on the baffle, and the positioning bolt is screwed into the nut sleeve and then passes through the baffle.

[0011] Compared with the prior art, the present invention has the following technical effects:

DETAILED DESCRIPTION

[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0024] Example 1:

[0025] See Figure 3-6 A flexible photovoltaic module installation cable traction device includes a traction column 10, wherein the traction column 10 includes a vertical rod 11 and a horizontal rod 12 welded to the vertical rod 11. The vertical rod 11 includes an upper and a lower part, and the upper and lower parts of the vertical rod 11 are hinged by a hinge structure 13. By setting the vertical rod 11 of the traction column 10 into an upper and a lower part, and the upper and lower parts are hinged by the hinge structure 13, when the steel wire rope 40 needs to be pulled and tensioned, Figure 1 , it is only necessary to further tighten the nut 31 on the pull rod 30, and the upper end of the vertical rod 11 can be tilted toward the side of the ground anchor 20, thereby tensioning the wire rope 40. With this structure, no additional auxiliary equipment is required when tensioning the wire rope 40, and the operation is simpler.

[0026] In this embodiment, see Figure 5 、 6 The hinge structure 13 includes two first lug plates 131 and a second lug plate 132, which are respectively mounted on the upper and lower parts of the vertical rod 11, and the second lug plate 132 is mounted between the two first lug plates 131. The first lug plate 131 and the second lug plate 132 are hingedly connected by a pin 134. Preferably, the ends of the first lug plate 131 and the second lug plate 132 are both arc-shaped structures.

[0027] Further, see Figure 5 The first ear plate 131 and the second ear plate 132 are only provided with an arc angle 133 on the same side. Specifically, the arc angle 133 is provided close to the ground anchor 20, so that the upper end of the vertical rod 11 can only tilt toward the ground anchor 20. Even if the ground anchor 20 or the pull rod 30 becomes loose, the wire rope 40 will not lose control.

[0028] Furthermore, the two first ear plates 131 and the second ear plate 132 are respectively provided on a connecting section 135. The vertical rod 11 is a tubular structure, and the two connecting sections 135 are respectively inserted into the upper and lower portions of the vertical rod 11 and fixedly connected to the upper and lower portions of the vertical rod 11. The provision of the connecting sections 135 facilitates the connection and fixation of the first ear plate 131 and the second ear plate 132 to the upper and lower portions of the vertical rod 11. Specifically, after the connecting sections 135 are inserted into the upper and lower portions of the vertical rod 11, they are welded and fixed.

[0029] Example 2:

[0030] Based on Example 1, see Figure 3 、 4 The upper part of the vertical rod 11 is also fixed with a baffle 14, which extends downward to the lower part of the vertical rod 11. This further prevents the upper end of the vertical rod 11 from tilting away from the ground anchor 20. Similarly, even if the ground anchor 20 or the pull rod 30 becomes loose, the wire rope 40 will not lose control. Figure 3 In the middle, due to the limitation of the baffle 14, the upper part of the vertical rod 11 is in a vertical state and cannot be tilted further to the right; Figure 4 In the embodiment, the upper portion of the vertical rod 11 is tilted to the left. In the present embodiment, the vertical rod 11 is a tubular structure, and the baffle 14 is an arc-shaped plate. The upper end of the baffle 14 is fixedly welded to the upper portion of the vertical rod 11.

[0031] Further, see Figure 4 A positioning bolt 15 is screwed onto the baffle 14 at one side of the lower portion of the vertical rod 11. After the wire rope 40 is tensioned, the upper portion of the vertical rod 11 tilts to the left. At this time, the positioning bolt 15 is tightened so that the positioning bolt 15 abuts against the outer wall of the lower portion of the vertical rod 11, thereby limiting the position of the upper portion of the vertical rod 11.

[0032] Furthermore, a nut sleeve 16 is installed on the baffle 14 at one side of the lower part of the vertical rod 11, and the positioning bolt 15 is screwed into the nut sleeve 16 and then passes through the baffle 14. The nut sleeve 16 is welded to improve the connection stability of the positioning bolt 15 and the baffle 14.

[0033] The working principle or action process of the utility model is as follows:

[0034] See also Figure 1 、 4 When the steel wire rope 40 needs to be pulled and tensioned, it is only necessary to further tighten the nut 31 on the pull rod 30, and the upper end of the vertical rod 11 can be tilted toward the ground anchor 20, thereby tensioning the steel wire rope 40. After the tensioning is completed, the positioning bolt 15 is tightened so that the positioning bolt 15 abuts against the outer wall of the lower part of the vertical rod 11. With this structure of the pulling device, no additional auxiliary equipment is required when tensioning the steel wire rope 40, and the operation is simpler.
