Description

Wind turbine with its own crane

technical field

The utility model relates to a wind power generator set, in particular to a wind power generator set with a crane, which can be applied no matter it is installed on the sea or on land.

Background technique

Whether it is the overall assembly of the wind turbine at the beginning or the fault maintenance in the future, hoisting equipment is required to lift parts through the hoisting equipment.

At present, the commonly used hoisting equipment for wind turbines mainly includes large crawler cranes, wheeled cranes, hoisting ships, etc. These hoisting equipment not only have high rental costs, but also are bulky and heavy in structure. Especially when lifting the components of offshore wind turbines, there are many difficulties. In order to overcome the above-mentioned defects of the hoisting equipment, some manufacturers of wind turbines have devoted a large amount of money to research suitable hoisting equipment for wind turbines, and these research results have been frequently reported in public publications. For example, the "Maintenance Crane for Large Wind Power Generating Sets" disclosed in Chinese patent literature (publication number: CN 201395498Y, publication date: February 3, 2010), the maintenance crane consists of two parts, the smaller part ( Such as hooks, pulley blocks, etc.) are installed in the nacelle of the wind turbine, and the larger part (such as hoist, control cabinet, etc.) is installed on the bottom platform of the wind turbine. Although it can effectively replace the aforementioned lifting equipment, its It has seriously affected the normal operation of the wind turbine, especially the yaw operation of the wind turbine. In addition, its steel wire rope and other components have been exposed for a long time, which is extremely unsuitable for use in the offshore environment. Corrosive and easily damaged; another example, the "wind turbine and its maintenance crane" disclosed in the Chinese patent literature (CN 201746245U, publication date: February 16, 2011), although this technology arranges the crane In the engine room, but the crane used is an electric hoist crane, the lifting weight is limited, and it is impossible to lift large parts, so the practicability is poor.

Contents of the invention

The purpose of this utility model is to provide a wind power generating set with its own crane under the premise of not affecting the normal operation of the unit in view of the above-mentioned deficiencies in the prior art. Reliable, practical and other characteristics.

The technical scheme adopted by the utility model is: a wind power generating set with its own crane, including the crane, the crane is arranged in the nacelle of the wind power generating set, and forms an integrated structure with the nacelle of the wind power generating set.

The crane is mainly composed of a frame, a cart mechanism, a lifting trolley, a spreader and a control system; wherein, the frame is laid in the cabin of the wind power generating set and is used as a supporting cart mechanism, and a There is a track for the longitudinal operation of the cart mechanism; the cart mechanism is used to assemble the lifting trolley, and a track for the horizontal movement of the lifting trolley is provided on the cart mechanism; the lifting trolley is connected with the spreader through a wire rope, The lifting trolley and the trolley mechanism form a rectangular working range; the control system is used to control the movement of the trolley mechanism and the trolley.

The control system is a control handle with wired connection or wireless remote control.

The hanger consists of a main hook and an auxiliary hook.

The nacelle is provided with hoisting holes corresponding to the spreader of the crane.

The beneficial effects of the utility model are: the crane is integrated and arranged in the engine room of the wind power generating set, the structure is simple and compact, the cost is low, and the normal operation of the wind power generating set will not be affected, and the reliability is high; the crane adopts a traditional bridge crane Structure, wide working range, large lifting capacity, flexible and convenient operation, high stability and strong practicability.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is further described.

Fig. 1 is a reference diagram of a use state of the utility model.

Fig. 2 is a schematic diagram of A-A in Fig. 1 .

Detailed ways

Referring to Fig. 1 and Fig. 2: the utility model comprises a crane, and the structure of the crane is similar to the structure of the traditional bridge crane, but the size and specification should be smaller than that of the traditional bridge crane, and the crane is arranged in the engine room 4 of the wind power generating set. An integrated structure is formed with the nacelle 4 of the wind power plant.

The above-mentioned crane is mainly composed of a frame 1, a cart mechanism 2, a lifting trolley 3, a spreader and a control system. Among them, the frame 1 is laid in the nacelle 4 of the wind turbine, used to support the cart mechanism 2, and ensure that other mechanisms of the crane and the components of the wind turbine (including control cabinets, gearboxes, main shafts, couplings, etc.) No collision is formed, and the frame 1 is provided with a track for the operation of the cart mechanism 2, and the track is made of I-beam. The cart mechanism 2 is installed on the track of the frame 1 through guide wheels and other components. Under the action of the drive motor, the cart mechanism 2 runs longitudinally along the track on the frame 1; the cart mechanism 2 is used to assemble the lifting trolley 3. On the cart mechanism 2, there is a track for the lifting trolley 3 to run laterally. The lifting trolley 3 is composed of a hoisting mechanism, a trolley running mechanism and a trolley frame; the hoisting mechanism includes a motor, a reducer, a rope puller (that is, a reel), a speed-increasing pulley block, and a brake device; the trolley frame is a support, The frame for installing components such as the lifting mechanism and the trolley running mechanism is usually a welded structure; the hoisting trolley 3 is connected to the spreader through a wire rope 8, and the combination of the hoisting trolley 3 and the trolley mechanism 2 forms a rectangular working range. As for wind turbine components, the lower space can be fully utilized without being hindered by other equipment in the nacelle 4; the control system is used to control the movement of the driving motor of the cart mechanism 2 and the motor of the lifting trolley 3, and the control system is an electric hoist Hang the control handle 7 commonly used, handle light and handy, nimbly, it can be wired connection mode, also can be wireless remote control mode, and the present embodiment is wired connection mode.

Above-mentioned sling is made up of main hook 5 and auxiliary hook 6, and on the bottom surface of nacelle 4, is provided with corresponding hoisting hole for sling, namely main hook 5 corresponds to main hoisting hole, and auxiliary hook 6 corresponds to auxiliary hoisting hole. The main hook 5 can be used to lift all parts in the nacelle 4, and the auxiliary hook 6 is used to lift smaller parts.
