Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic assembly construction, and in particular relates to a method for using a centralized fixed bracket photovoltaic assembly installation work platform. Background Art

[0002] In recent years, new energy projects such as photovoltaic power stations have developed explosively in China, and a large number of photovoltaic power station construction projects have been planned in non-agricultural land such as Gobi, mountainous areas, and water areas across the country. Photovoltaic module installation is one of the key processes in the construction of photovoltaic power stations, and the installation efficiency of photovoltaic modules determines the length of the construction period of photovoltaic power stations. Photovoltaic module installation brackets have been widely used in mountainous areas, Gobi and other areas. Previously, gantry scaffolding, ladders or climbing vehicles were mostly used.

[0003] In mountainous areas, Gobi Desert and other regions, due to the terrain, flood control, photovoltaic and animal husbandry complementarity, and dust burial prevention requirements, photovoltaic module supports are usually relatively high, with the highest end generally exceeding 3m. In this case, it is impossible to install the modules manually alone.

[0004] The existing portal scaffolding has the advantages of being structurally sound, not requiring reliance on existing fixed photovoltaic supports, and having large turnover space.

[0005] The shortcomings of the existing portal scaffolding are that the bracket is heavy and the adjustment of its position requires the cooperation of multiple people. After the installation of this part group is completed, it needs to be adjusted and translated as a whole before it can continue to be used. It cannot be used safely on uneven terrain or soft geology. The cost of use is high, and most of them are standardized, and it is impossible to find a size that is perfectly suitable for actual on-site construction.

[0006] The existing ladder has the advantages of simple structure, easy movement, low cost of use and large turnover space.

[0007] The existing ladders have the disadvantages of being unable to meet the requirements of multi-person collaborative installation, having low operational safety guarantees, and being unable to be safely used on uneven terrain or in areas with soft geology.

[0008] The existing aerial work vehicles have the advantages of being able to collaborate with multiple people in construction, having a high safety factor in construction work, not needing to rely on existing photovoltaic brackets, and not requiring manual movement.

[0009] The disadvantages of existing aerial work vehicles are that the photovoltaic power station construction area is wide, a large number of aerial work vehicles are needed, the construction cost is too high, and it cannot be used safely on uneven terrain or soft geology. Summary of the invention

[0010] In order to overcome the technical problems in the prior art, the present invention provides a method for using a centralized fixed bracket photovoltaic component installation work platform to solve the above-mentioned technical problems.

[0011] A centralized fixed bracket photovoltaic module installation work platform consists of 3 support frames + a work platform + a protective structure. The support frame consists of a load-bearing hook, a main load-bearing rod, a second diagonal rod, a first-layer diagonal rod, a second-layer cross bar, a diagonal support rod, a work platform limit structure, and a first-layer cross bar, and is divided into an upper and lower structure.

[0012] The working platform is made of long steel strips that are reliably connected. Its size is smaller than the working platform limit structure and its length is greater than the span of the photovoltaic module installation bracket.

[0013] The protective structure is composed of a protective force-bearing structure and a protective rope hanger effectively connected to the second-layer inclined rod. The protective structure is formed by hanging a protective rope on the protective rope hanger.

[0014] The load-bearing hook is made of a steel hook and is provided with a buffer pad to avoid direct contact between the steel hook and the support column. It is the connecting part between the upper part of the working platform and the photovoltaic support.

[0015] The main load-bearing rod is made of long steel strips and is the main load-bearing column of the support frame. It is connected to the other components by welding or bolts.

[0016] The protective load-bearing structure is welded from long steel strips and is part of the support frame protection structure. It is connected to other components by welding or bolts.

[0017] The protective rope hanger is made of arc-shaped flat steel, which is connected to the protective force-bearing structure by welding or bolts, and is the hanging part of the protective rope. The protective rope is made of steel strands or steel chains, etc., which are firmly fixed with safety buckles and hung on the protective chain hanger to form a protective structure.

[0018] The first layer of inclined braces is made of long steel strips, which is the tension-bearing structure of the first level of the support frame and is connected to the other components by welding or bolts. The second layer of inclined braces is made of long steel strips, which is the tension-bearing structure of the second level of the support frame and is connected to the other components by welding or bolts.

[0019] The first-layer cross bar is made of long steel strips and is the supporting part of the first-layer cross bar. It is connected to the other components by welding or bolts. The second-layer cross bar is made of long steel strips and is the placement part of the working platform. It is connected to the other components by welding or bolts.

[0020] The diagonal brace is made of long steel strips and is the supporting part of the second-layer crossbar. It is connected to the remaining components by welding or bolts.

[0021] The limit clamp is made of steel, which serves to fix the main load-bearing rod and is connected to the main load-bearing rod by bolts.

[0022] The limiting C-shaped steel is made of C-shaped steel and is connected to the first-layer crossbar with bolts to serve as a fixed support frame.

[0023] The working platform limiting structure is a rectangular structure formed by long steel strips, which is effectively connected to the cross bar or to limit the adverse displacement of the working platform. The working platform is made of long steel strips that are reliably connected to provide a working platform for personnel.

[0024] A method for using a centralized fixed bracket photovoltaic assembly installation work platform comprises the following steps:

[0025] S1: Each group of working platforms consists of three support frames and two working platforms;

[0026] S2: Because the support frame is very light, a worker hangs the support frame on the rear column of the photovoltaic bracket, tightens the lower clamp, and then uses hinges and the rear diagonal brace to fix it firmly;

[0027] S3: After the three supporting frames are hung, the working platform is placed and fixed. There are two layers of working platforms, and one working platform is placed on each layer;

[0028] S4: Workers climb up the support frame in two steps to hang the upper clamp and protective rope, and buckle the five-point safety belt on the upper photovoltaic support;

[0029] S5: The installation of the photovoltaic modules begins. Workers stand on the work platform in two layers, two on the first layer and one on the second layer.

[0030] S5: After the installation of the span component is completed, the worker climbs down the support frame, pushes the working platform toward the unused third auxiliary support frame, removes the vacant support frame, and installs it in the next span where the bracket is to be installed, thereby achieving continuous operation.

[0031] In general, the above technical solutions conceived by the present invention can achieve the following beneficial effects compared with the prior art:

[0032] 1. The centralized fixed bracket photovoltaic module installation work platform described in the present invention greatly increases the safety of use compared with ladders or other unconventional simple installation methods, and there is no need to consider the photovoltaic bracket when using it;

[0033] 2. The centralized fixed support photovoltaic module installation work platform described in the present invention increases construction efficiency and reduces construction costs compared to existing work supports and equipment such as gantry scaffolding and aerial work vehicles;

[0034] 3. The centralized fixed bracket photovoltaic module installation work platform described in the present invention simplifies the construction method of photovoltaic module installation, increases the construction efficiency of module installation, reduces the construction cost investment, and has a wider range of use in the photovoltaic construction industry;

[0035] 4. After the installation of the centralized fixed support photovoltaic module installation work platform described in the present invention is completed, the single-layer work platform can be pushed flatly to the next span support frame, without the need to move the entire scaffolding like a conventional scaffolding. Since the installation work platform has two layers of work platforms, the photovoltaic modules on the entire photovoltaic support plane can be installed and constructed at the same time, which greatly improves the construction efficiency;

[0036] 5. Compared with conventional brackets that rely on photovoltaic brackets for component installation, the force-bearing structure design of the present invention can effectively avoid adverse damage to the photovoltaic bracket. The core force point is at the top of the rear column of the bracket, and the force direction is vertical. The bearing capacity of the rear column of the bracket is greater than the deadweight and construction load of the present invention itself, and will not affect the accuracy of the installed photovoltaic bracket.
