Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic truss installation, in particular to a truss hoisting ship. Background Art

[0002] The photovoltaic support truss is a way to fix the photovoltaic support. In the application of the truss-type photovoltaic support for large-area installation of photovoltaics on water, it mainly includes columns, trusses, truss supports, hoop fasteners, purlins, purlin supports, diagonal ties, straight ties, etc., all of which are processed from square tubes, angle steels and C-shaped steels.

[0003] The truss is generally processed in a factory and then transported to the installation site as a whole. Appropriate numbers of pipe piles are driven into the water according to the installation position of the truss, and then the truss is assembled into the corresponding pipe piles. The truss size is 12m×0.08m×0.86m (length×width×height), and the single-piece weight is about 180 kg. The installation height of the truss is about 3.5 m from the water surface. There are two existing installation methods: one is to erect a gin pole. First, install the gin pole, then install a winch on the gin pole, and then hoist the truss through the winch. This method is mainly for trusses with a small installation quantity; the other is to use a floating crane for hoisting. Due to the large size of the floating crane, it is inconvenient to walk between the pipe piles, reducing the installation efficiency. In addition, the entry and exit, rental costs of the floating crane are relatively high. Summary of the Utility Model

[0021] The present utility model will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other. For the convenience of description, words such as "upper", "lower", "left", and "right" hereinafter only indicate the same directions as the upper, lower, left, and right of the accompanying drawings themselves, and do not limit the structure.

[0022] As Figure 1 shown, a truss hoisting ship provided in this embodiment includes a support frame 1, a pontoon 2, a track 3, an electric hoist 4, an equipment platform 5, an operation platform 6, and a generator 7.

[0023] The number of the pontoons 2 is multiple, and they are vertically connected to the bottom of the support frame 1 on the horizontal plane. The support frame 1 includes three cross bars 11, three vertical bars 12, two diagonal braces 13, and multiple reinforcing pipes 14. The three cross bars 11 are arranged at intervals, and the interval between two of the cross bars 11 is adapted to the size of the pontoon 2, and these two cross bars 11 are located on the upper and lower sides of the pontoon 2; the interval of the other cross bar 11 is preferably 200 mm lower than the lowest end of the installed truss 8, and this cross bar 11 is located above the pontoon 2. The three vertical bars 12 are respectively located at both ends and in the middle of the cross bar 11. The two diagonal braces 13 are connected in an "X" shape between the vertical bar 12 and the cross bar 11. Multiple reinforcing pipes 14 are vertically connected to the cross bar 11, the reinforcing pipes 14 are parallel to the pontoon 2, and every two of the reinforcing pipes 14 are arranged close to the pontoon 2 and are tied to the pontoon 2 through fasteners (such as scaffolding fasteners). An equipment platform 5 is arranged on the reinforcing pipe 14 at the upper end of the pontoon 2. The equipment platform 5 is made of wood board and is tied to the cross bar 11 and the reinforcing pipe 14 through fasteners. A generator 7 is placed on the equipment platform 5, and the generator 7 is used to provide electrical energy for the hoisting ship.

[0024] Multiple reinforcing pipes 14 are arranged in a row on the cross bar 11 above the pontoon 2, and an operation platform 6 is laid on the multiple reinforcing pipes 14. The operation platform 6 is made of wood board and is tied to the reinforcing pipe 14 through fasteners.

[0025] The tops of the three vertical bars 12 are horizontally connected with a track 3 dedicated for an electric hoist. The track 3 horizontally extends out of one end outside the support frame 1, and this end is the operation end, so that the electric hoist 4 can move to the outside of the support frame 1 to hoist the truss 8. Or, according to needs, the track 3 can extend out of both ends of the support frame 1 so that both ends are operation ends. The height of the track 3 is preferably about 1.5 m higher than the uppermost end of the installed truss 8 to leave a hoisting distance.

[0026] In this embodiment, the hoisting ship is designed with a size of 6m × 3m (length × width), and a total of 21 plastic floats with a size of φ800 × 900mm are used. After assembly, the size is 6m × 3m × 5.5m. The generator 7 is arranged on the side opposite to the hoisting direction of the hoisting ship, which can play a role in counterweight. The track 3 and the vertical rod 12 are connected by a reinforcing pipe 14. The reinforcing pipe 14 at this position needs to be considered so as not to interfere with the movement of the electric hoist 4. Except for connecting the track 3, the rest of the reinforcing pipe 14 is a steel pipe with a size of φ48 × 3500mm.

[0027] Before hoisting, the hoisting ship should undergo a load test. Since the weight of the hoisted truss 8 reaches 180kg, a load test is carried out at 1.5 times, that is, 270kg, to verify the hoisting performance and anti-overturning performance of the hoisting ship.

[0028] When the hoisting ship is hoisting, first use a transport ship to transport the truss 8 to the side of the hoisting ship, and fix the hoisting ship to the pipe pile 9 with a hemp rope. Operate the electric hoist 4 to move to the position of the truss 8, and lift the truss 8 through a steel wire rope and a hook, and insert the bottom of the truss 8 into the pipe pile 9. After installing one truss 8, move the hoisting ship back to the installation position of the next truss 8, and then tie it to the pipe pile 9 at this position with a hemp rope. The truss transport ship also moves to the side of the hoisting ship and hoists the next truss 8 according to the above steps. Repeat the above steps to complete the hoisting of all trusses 8 in turn.

[0029] In a 100MWp fishery-solar complementary photovoltaic power generation project in a certain town, two hoisting ships are configured. There are a total of 5629 trusses for the photovoltaic brackets. According to the traditional installation method, each group of workers can install 25 - 30 trusses per day. After using the hoisting ship of the present utility model, each group of workers can install 50 - 60 trusses per day, and the labor cost can be saved by 50%. The entry and exit fees and rental fees of floating cranes are also saved.

[0030] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be included in the patent protection scope of the present utility model by the same token.
