Description

Technical Field

[0001] The present invention belongs to the technical field of installation of photovoltaic flexible brackets, and particularly relates to a hanging bracket for spanning between rows of photovoltaic flexible brackets and a using method thereof. Background Art

[0002] The photovoltaic flexible bracket mainly consists of a cross beam, steel cables (including steel cables for fixing photovoltaic modules and load-bearing steel cables), guy wires, and ground anchors / side anchors. The photovoltaic modules are generally 4m above the ground. During the installation process of the photovoltaic flexible bracket, operators need to perform high-altitude operations. If a scaffold is erected on the ground, the workload is relatively large. Coupled with the large floor area of the photovoltaic power station, the photovoltaic modules will move at any time during the installation process (including the movement of the steel cables for fixing photovoltaic modules within the same row and the movement of the steel cables for fixing photovoltaic modules between rows). Therefore, at present, a hanging bracket is mostly used as an installation platform. The hanging bracket includes a pedal and a hook. The pedal is made of steel plate, and its area is generally 2-4m 2 and weighs dozens of catties. The movement of the hanging bracket within the same row of the steel cables for fixing photovoltaic modules is relatively simple, but the movement between rows of the steel cables for fixing photovoltaic modules is relatively difficult because it cannot slide along the steel cables and needs to span different steel cables for fixing photovoltaic modules.

[0003] Based on the above introduction of the prior art, the technical problem to be solved by the present invention is to improve the existing hanging bracket to reduce the difficulty of spanning between rows of the steel cables for fixing photovoltaic modules. Summary of the Invention

[0039] In the figure: pedal 1, flexible hook 2, support tube 201, hook body 202, pull rope 203, externally threaded connection tube 204, sealing ring plate 204.1, baffle plate 204.2, ball 204.3, wire outlet hole 205, guide wheel assembly 206, pull rope storage rack 207, pull ring 208, ear plate 3, photovoltaic module fixing steel cable 4, high-position rope 401, low-position rope 402. Detailed implementation method

[0040] Example 1:

[0041] The preferred solution is as Figures 1 to 10 shown. A hanging bracket for spanning between rows of a flexible photovoltaic bracket includes a pedal 1. A plurality of flexible hooks 2 are detachably provided on the pedal 1. The flexible hook 2 includes a support tube 201. A hook body 202 is provided at the top of the support tube 201. The bottom of the support tube 201 is detachably connected to the pedal 1, and the support tube 201 is connected to the pedal 1 through a pull rope 203. The pull rope 203 is a hemp rope. The pull rope 203 is not used for load bearing but for pulling the pedal 1, facilitating the operator to pull up the pedal 1 while standing on the steel cable. When it is necessary to perform the operation of spanning between rows, first lower the pedal 1 to the ground. On the one hand, it can reduce the overall weight during the movement of the hanging bracket. On the other hand, the hard-connected hook is changed to a flexible hook 2. When the operator hangs the flexible hook 2 on the fixing steel cable of another row of photovoltaic modules, the difficulty will be greatly reduced. In addition, other operators on the ground are not required to help during the entire transfer process, which is beneficial to saving labor.

[0042] Furthermore, the connection method between the pedal 1 and the flexible hook 2 is as follows: an internal thread hole is provided on the pedal 1. The internal thread hole is connected to the externally threaded connection tube 204. The externally threaded connection tube 204 is rotatably connected to the support tube 201. A sealing ring plate 204.1 and a baffle plate 204.2 are provided at the top of the externally threaded connection tube 204. A ball 204.3 is provided between the sealing ring plate 204.1 and the baffle plate 204.2. The baffle plate 204.2 is fixed to the bottom of the support tube 201. A wrench bayonet or a hexagonal prism or a quadrangular prism is provided on the outer wall of the externally threaded connection tube 204. Rotate the externally threaded connection tube 204 with a wrench to install it on the internal thread hole of the pedal 1. The support tube 201 is a hollow structure. On the one hand, it can reduce the weight of the flexible hook 2. On the other hand, it is used to thread the pull rope 203 inside the support tube 201. The pull rope 203 mainly penetrates into the support tube 201 from the internal thread hole and then passes out through the wire outlet hole 205 on the outer wall of the support tube 201. For the part above the wire outlet hole 205, the support tube 201 can be a solid rod.

[0043] Furthermore, a plurality of ear plates 3 are provided on the ground of the pedal 1. The ear plates 3 are connected to the pull rope 203. The pull rope 203 penetrates into the support tube 201 from the inside of the externally threaded connection tube 204 and passes out through the wire outlet hole 205 on the outer wall of the support tube 201.

[0044] Further, a guide wheel assembly 206 is provided on the outer wall of the support tube 201. The guide wheel assembly 206 is located above the wire outlet hole 205. The guide wheel assembly 206 includes guide wheels or guide rollers, which are used to reduce the friction force of the pulling rope 203 during the pulling process and prevent the pulling rope 203 from being worn and broken.

[0045] Further, a pulling rope storage rack 207 is provided on the support tube 201. The pulling rope storage rack 207 is used to store the excess pulling rope 203. In this embodiment, the pulling rope storage rack 207 is two support columns distributed up and down.

[0046] Further, one end of the pulling rope 203 is tied to the ear plate 3, and a pull ring 208 is provided at the other end of the pulling rope 203. The diameter of the pull ring 208 is larger than the diameter of the wire outlet hole 205. The pull ring 208 is used to play a limiting function to prevent the pulling rope 203 from falling off from the wire outlet hole 205.

[0047] The flexible hook 2 includes a hook for hanging the high-end rope and a hook for hanging the low-end rope. The length of the hook for hanging the high-end rope is longer than that of the hook for hanging the low-end rope. The number of hooks for hanging the high-end rope is at least two, and the number of hooks for hanging the low-end rope is at least two. The height difference between the hook for hanging the high-end rope and the hook for hanging the low-end rope is determined according to the height difference between the high-position rope and the low-position rope.

[0048] Preferably, the usage method of the hanger for spanning between rows of the photovoltaic flexible bracket is as follows:

[0049] Initial state: The hanger is hung on the A-row photovoltaic flexible bracket. The support tube 201 is fixed on the pedal 1 through the external thread connecting cylinder 204. The hook for hanging the high-end rope is hung on the high-position rope of the photovoltaic flexible bracket, and the hook for hanging the low-end rope is hung on the low-position rope of the photovoltaic flexible bracket. The pulling rope 203 is stored on the pulling rope storage rack 207;

[0050] The process of spanning between rows is as follows:

[0051] Step S1: Rotate the external thread connecting cylinder 204 to separate the support tube 201 of the flexible hook 2 from the pedal 1; The operator stands on the load-bearing steel cable, and the hook of the safety belt is hung on the photovoltaic module fixing steel cable;

[0052] Step S2: Loosen the pulling rope 203 to lower the pedal 1 from the air to the ground;

[0053] Step S3: Transfer the hooks for hanging the high-end ropes and the hooks for hanging the low-end ropes to the high-position ropes and low-position ropes of the B-row photovoltaic flexible brackets in sequence; the ropes of the photovoltaic flexible brackets are generally steel cables, which are divided into photovoltaic module fixing steel cables and load-bearing steel cables. The photovoltaic module fixing steel cables are used to install photovoltaic modules, and the load-bearing steel cables are used to install photovoltaic wind-resistant support rods; since the photovoltaic modules are installed at a certain inclination angle, the photovoltaic module fixing steel cables are distributed at different heights. The steel cable at a higher position is defined as the high-position rope, and the steel cable at a lower position is defined as the low-position rope; in this step, it is also possible to: transfer the hooks for hanging the low-end ropes and the hooks for hanging the high-end ropes to the low-position ropes and high-position ropes of the B-row photovoltaic flexible brackets in sequence.

[0054] Step S4: The operator transfers to the B-row photovoltaic flexible brackets; the operator directly steps from the A-row steel cables onto the B-row steel cables; without carrying heavy items, the operator can move or cross the steel cables relatively easily. However, when carrying a hanging bracket weighing dozens of catties or nearly a hundred catties to cross, it is very difficult and prone to safety accidents; therefore, in the present invention, the heaviest pedal 1 is placed on the ground to reduce the weight of the entire hanging bracket. First, transfer the flexible hook 2, then lift the pedal 1, and then fix the pedal 1 to the flexible hook 2. This can not only reduce the difficulty of crossing between rows but also avoid the operator repeatedly climbing the photovoltaic flexible brackets.

[0055] Step S6: The operator uses the pull rope 203 to pull up the pedal 1 until the pedal 1 is close to the flexible hook 2.

[0056] Step S9: Rotate the external thread connecting cylinder 204 to connect the support tube 201 of the flexible hook 2 to the pedal 1.

[0057] Step S12: Store the pull rope 203 on the pull rope storage rack 207 and tie it tightly.

[0058] The process of crossing between rows of the hanging bracket is completed.

[0059] The above embodiments are only the preferred technical solutions of the present invention and should not be regarded as limitations on the present invention. The protection scope of the present invention should be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, the equivalent replacement improvements within this scope are also within the protection scope of the present invention.
