Description

Technical Field

[0001] This utility model relates to the field of flexible photovoltaic support technology, and in particular to an auxiliary device for tensioning steel cables of flexible photovoltaic supports. Background Technology

[0002] In mountain photovoltaic projects, steep slopes, undulating terrain, and various irregular changes are often encountered. Under these complex mountain conditions, the drawbacks of traditional fixed photovoltaic support structures are becoming increasingly apparent. Due to the complexity of the terrain, traditional fixed photovoltaic support structures cannot be used for installation in many cases, reducing land use efficiency and affecting the overall photovoltaic power generation capacity.

[0003] Existing technology, CN2024118381641, describes a three-cable flexible photovoltaic support system. Currently, among the various types of photovoltaic supports, flexible supports using steel cables are becoming increasingly common. Tensioning the steel cables requires tensioning equipment, with common hydraulic tensioning jacks weighing approximately 25 kg. Flexible supports are typically erected quite high, and construction workers often need to carry the jacks while tensioning, which is extremely strenuous. Therefore, actual installation carries certain risks and requires multiple people to work in shifts, resulting in low efficiency and high labor costs.

[0004] Therefore, it is necessary to design an auxiliary device for tensioning steel cables of photovoltaic flexible supports to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary device for tensioning steel cables of photovoltaic flexible support structures, so as to overcome the above-mentioned shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An auxiliary device for tensioning steel cables in photovoltaic flexible support structures includes an installation column, a column crossbeam placed on the column for cooperating with the installation of the steel cable, a tensioning device installed in cooperation with the column crossbeam, and a jack suspended from the tensioning device by a rope. The tensioning device includes a crossbeam, an anti-disengagement hook at one end of the crossbeam, a limiting slot assembly at the other end that conforms to the shape of the column crossbeam, and a transfer handle extending outward from one end of the limiting slot assembly.

[0008] Preferably, the limiting slot assembly consists of a limiting horizontal bar, a limiting front vertical bar, and a limiting rear vertical bar. The limiting front vertical bar and the limiting rear vertical bar are respectively disposed at both ends of the limiting horizontal bar, and the limiting rear vertical bar is disposed on the side near the transfer handle. The limiting horizontal bar is placed on the top surface of the column beam, and the limiting rear vertical bar is placed on the outer front wall of the column beam.

[0009] Preferably, the front limiting vertical rod has a U-shaped structure.

[0010] Preferably, steel cable hooks are provided on both sides of the end of the rear limiting vertical rod, and the steel cable hooks are inclined upward.

[0011] Preferably, the crossbeam and the limiting slot assembly are connected by diagonal bracing.

[0012] The beneficial effects of this utility model are: This technical solution designs a tooling for installing columns and beams, and uses a tensioning device to hang the jack for tensioning, which facilitates the tensioning of steel cables, greatly reduces the labor intensity of construction workers, and the tooling is lightweight, easy to use, safe and reliable.

[0018] Reference Figures 1 to 4 An auxiliary device for tensioning steel cables of a photovoltaic flexible support includes an installation column 1, a column beam 2 placed on the column and used to cooperate with the installation of the steel cable, a tensioning device 3 installed in cooperation with the column beam, and a jack 4 suspended on the tensioning device by a rope.

[0019] The tensioning device includes a crossbeam 31, an anti-disengagement hook 32 placed at one end of the crossbeam, a limiting slot assembly 33 placed at the other end and configured to mimic the shape of the column crossbeam, and a transfer handle 34 placed at one end of the limiting slot assembly and extending outward.

[0020] The tensioning device is welded from round or square tubes, which is simple in structure and easy to carry. The anti-detachment hook 32 is to prevent the jacking rope from falling off and ensure safety. After the tensioning device 3 is installed with the column beam 2, it can be manually moved by the transfer handle 34 to adjust the position or move it significantly. The limiting slot assembly 33 is used to install with the column beam 2 and matches the shape of the column beam.

[0021] The limiting slot assembly 33 consists of a limiting horizontal bar 331, a limiting front vertical bar 332, and a limiting rear vertical bar 333. The limiting front vertical bar and the limiting rear vertical bar are respectively located at both ends of the limiting horizontal bar, and the limiting rear vertical bar is located on the side near the transfer handle 34. The limiting front vertical bar has a U-shaped structure and fits against the outer rear wall of the column beam (near the manual side) during use. The limiting horizontal bar is placed on the top surface of the column beam, and the limiting rear vertical bar is placed on the outer front wall of the column beam (i.e., the side where the steel cable enters). The column beam is limited and fixed by wrapping it on three sides.

[0022] The rear limiting vertical rod is provided with steel cable hooks 334 on both sides, and the steel cable hooks have an upward angle. When in use, they are used to hook the steel cable to be tensioned to prevent the tooling from falling off.

[0023] To enhance the overall structural strength, the crossbeam 31 and the limiting slot assembly 33 are connected by diagonal bracing 5.

[0024] In this implementation case, steel cables are generally installed on both sides of the column and beam, so two sets of tensioning devices are usually required. One set will be used for explanation. (Refer to...) Figure 1 An installation platform 6 is erected next to the installation column 1. The limiting slot assembly 33 of the tensioning device 3 is clamped onto the column beam, with one end of the anti-disengagement hook 32 close to the manual side. The manual operator moves the device to the slot position for installing the steel cable on the column beam using the transfer handle 34 with auxiliary force. The steel cable hook 334 hooks onto the steel cable 7 to be tensioned. The limiting slot of the tensioning fixture matches the shape of the main beam. The jack is then hung on the beam of the tensioning fixture with a rope, and the steel cable passes through the installation hole of the column beam and is fixedly connected to the jack through a fixing device. The fixing device is a structure that works with the steel cable and can be a clamping mechanism or a fixing fixture. In actual operation, the two steel cables need to be tensioned simultaneously, requiring two sets of tensioning fixtures, with two construction workers each responsible for operating one jack. During the tensioning process, the jacks hold the column beams in place. The jacks work, causing the jack body to move backward. Since the hanging rope can slide on the beam 31 of the tensioning device, after the jacking is lifted, the steel cable moves backward synchronously, thereby tensioning the rope.

[0025] The advantages of this utility model are that this technical solution designs a tooling for installing columns and beams, and uses a tensioning device to hang the jack for tensioning, which facilitates the tensioning of steel cables, greatly reduces the labor intensity of construction workers, and the tooling is lightweight, easy to use, safe and reliable.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
