Description

Technical Field

[0001] The invention belongs to the technical field of assembled hanging beams, and in particular relates to an assembled hanging beam used for hanging a photovoltaic bracket. Background Art

[0002] In the construction of offshore photovoltaic installation, the photovoltaic bracket hoisting, which belongs to the category of precision hoisting, is indispensable, and the construction ship must be in a bottom-seated or pile-inserted state to maintain stability. At present, due to the relatively special offshore construction environment, the photovoltaic module transport ship is more obviously affected by the swell, resulting in a relatively large overall shaking of the ship, especially in the photovoltaic bracket hoisting process. If the photovoltaic module is directly hoisted and installed, it is very likely to cause the photovoltaic bracket to collide with the transport rack and cause serious damage or destruction to the outer surface of the photovoltaic bracket or even the overall structure, thereby affecting the construction progress and increasing the maintenance cost. Therefore, it is necessary to design an assembled lifting beam for photovoltaic bracket hoisting. Summary of the invention

[0003] The purpose of the present invention is to provide an assembled hanging beam for hanging a photovoltaic bracket to solve the problems raised by the above-mentioned background technology.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is an assembled hanging beam for hanging a photovoltaic bracket, comprising two main beams, with detachably connected side beams arranged between the two ends of the two main beams, detachably connected small hanging beams arranged below the two ends of the main beams, main hanging ears arranged on the upper end faces of the two ends, an upper side hanging ear connected to the side beams arranged on one side of the main hanging ear, a plurality of lower hanging ears arranged below the small hanging beams, and the side beams are inverted triangle truss structures.

[0005] Furthermore, lower lifting ears are provided at both ends and the middle part of the small hanging beam.

[0006] Furthermore, symmetrical lower hanging ears are provided between the two ends and the middle part below the small hanging beam.

[0007] Furthermore, a reinforcing plate is provided between the upper side lifting lug and the main lifting lug.

[0008] Furthermore, the main lifting lug is inclined, and the angle between the main lifting lug and the length direction of the small lifting beam is in the range of 30° to 40°.

[0009] Furthermore, the main beam is composed of a plurality of detachably connected rectangular trusses.

[0010] Furthermore, the side beam is composed of a plurality of sections of detachably connected inverted triangle truss structures.

[0011] Furthermore, the length direction of the small suspension beam is consistent with the length direction of the main beam.

[0012] Furthermore, the lower hanging ear and the hanging point of the photovoltaic bracket are on the same plumb line.

[0013] Furthermore, a lower side lifting ear is provided below the main beam, and an ear plate is provided on the small lifting beam, and the ear plate is detachably connected to the lower side lifting ear.

[0014] The present invention has the following beneficial effects: the overall weight of the present invention is relatively light, and most of the existing floating cranes can realize the single-hook lifting of the assembled lifting beam and the load-bearing of the photovoltaic bracket, and the horizontal lifting of the lifted photovoltaic bracket can be ensured by adjusting the length of the rigging, thereby improving the safety factor in the lifting process; the amount of consumables is small, the manufacturing cost is low and the processing cycle is short, and the production can be completed and put into use in a short time, which has obvious effects on ensuring the construction period and saving costs, and has high work efficiency; the overall assembly is simple, which brings great convenience to its storage and transportation, and is provided with multiple sets of lower lifting ears, which can realize platform lifting of different sizes, and the lower lifting ears can be reasonably selected according to the center of gravity of the photovoltaic bracket and the position of the transport frame according to actual needs, with strong adaptability and good use effect.

[0025] The main beam 1 is composed of a plurality of detachably connected rectangular trusses.

[0026] The side beam 2 is composed of multiple sections of detachably connected inverted triangle truss structures. The main beam 1, the side beam 2 and each section of the truss of the connecting beam 5 are connected by high-strength bolts or special machined parts. Both ends of each truss are provided with docking flanges, and through holes with the same diameter as the high-strength bolts are reserved on the docking flanges. Each truss section is detachably connected by high-strength bolts. The main beam 1 and the side beam 2 are both square steel pipe structures.
