Description
Technical Field
The invention relates to the technical field of lifting of a wind driven generator cabin, in particular to a lifting appliance of the wind driven generator cabin.
Background
In order to continuously develop human energy, protect environment, realize low carbon economy and realize the development of clean energy, wind power is an important part of clean energy, has the characteristics of green and safety, and is widely applied in China in recent years.
The engine room is a core large component of the fan, and various key equipment and control systems are installed in the engine room. The cabin outline is generally a box-shaped framework structure, the outer surface of the cabin outline is provided with a resin housing, and an opening is reserved at the top of the housing and can be opened. Because the cabin is a core large part, the weight is large, the weight of the cabin is tens tons to hundreds tons generally, the bottom of the cabin is a yaw bearing, the bearing body is provided with a mounting hole, and the mounting hole corresponds to the mounting hole at the top of the tower and is fixedly connected through a bolt. When the yaw bearing surface of the cabin is required to be horizontal during installation, the yaw bearing surface of the cabin can be effectively docked with the tower, and if the levelness cannot meet the requirement, the docking difficulty is very high. Because the casting thickness of the cabin internal equipment has working conditions such as tolerance, deviation of the liquid level of the gear box, deviation of the placing position of the cable and the like, the deviations can cause deviation of the actual gravity center position of the cabin, and the deviation of the actual gravity center and the theoretical gravity center can indirectly cause change of the levelness of the lifted cabin during actual lifting, so that the installation cannot be performed. Therefore, the commonly used fan cabin lifting appliance has the problems that due to structural design reasons, a single-limb lifting rope is adopted, a lifting hole is unique, a lifting point is not adjustable and the like, and great influence is brought to cabin lifting operation; in addition, as various devices are arranged in the cabin, the space structure is compact, the lower hanging lanyard is easy to interfere with the cabin internal devices, and the angle of the lanyard needs to be adjusted timely for avoiding; in addition, because the external contour of the engine room is of an unequal diameter structure, the external diameter of the front end is large, the external diameter of the rear end is small, and the longitudinal beams of the I-shaped hanging beam in the prior art are mostly symmetrically arranged, so that when in hoisting operation, the slings arranged under the hanging beam cannot be guaranteed to be in a vertical hanging state under the influence of the contour of the engine room, and the stability and the safety are poor; in addition, when the lifting lug of the lifting appliance and the connecting bolt of the cabin are required to be removed after the lifting appliance is lifted in place, particularly the front end is provided with a lifting bolt, in practical operation, as the cabin is placed at high altitude, an operator can only operate in the cabin, the lifting lug can only weigh tens of kilograms, manpower is difficult to move, and only auxiliary operation can be carried out by means of a crane, so that when the lifting lug and the bolt move out of a cabin lifting point together, the bolt is very easy to fall off from the lifting lug, and if the bolt falls to the ground, the situation of ground personnel is very dangerous, and the potential safety hazard is very large.
Disclosure of Invention

Further, at least one hanging hole is formed in the front end lower hanging system lifting lug, a bolt radial limit stop block is arranged between the hanging holes, and a bolt axial limit plate is arranged on the upper portion of the stop block.
Preferably, slings of the upper suspension system, the front end lower suspension system and the rear end lower suspension system are flexible rigging, and the flexible rigging is one of a sling, a steel wire rope and a chain.
The invention has the technical effects that:
1. because the upper hanging system adopts the double-limb sling, besides being directly connected with the crown block or the crane, the hoisting stability is good relative to the single-limb sling, the shaking of the cabin caused by wind load is reduced, and the cabin is easy to be in butt joint with the tower barrel; the longitudinal beams of the I-shaped hanging beam are designed in unequal length, so that the longitudinal beams meet the requirements of actual working conditions, are matched with the outer contour of the cabin and can be consistent with the width of hanging points in the cabin, and the hanging cable can ensure the vertical hanging state, so that the stability and the safety are good; because the upper lifting lug and the lower lifting lug are respectively provided with at least one lifting hole, hole positions can be selected according to requirements, the balance degree of cabin lifting can be adjusted in real time by selecting the multiple holes, and meanwhile, the dip angle of a lower lifting system rigging and equipment inside a cabin can be adjusted; the front end lower hanging system and the rear end lower hanging system are provided with the front end lower hanging system lifting lug and the rear end lower hanging system lifting lug, so that the lifting appliance can be simply and conveniently fixedly connected with the engine room through bolts, and the safety and the reliability are realized.
2. The lifting holes are arranged on the lifting eyes of the front-end lower lifting system, so that the lifting fixed positions of the lifting appliance and the cabin can be conveniently selected according to the needs, and the universality is good; the radial limit stop of the bolt is arranged between the hanging holes, so that the bolt can be prevented from rotating when the nut is fixed, an additional fixing tool is not needed, the installation and the disassembly are convenient, the risk of high-altitude operation is reduced, and the safety, the time saving and the labor saving are realized; because the bolt axial limiting plate is arranged on the upper portion of the stop block, the bolt can be effectively prevented from falling off from the lifting lug, potential safety hazards are eliminated, and the disassembly and assembly operations are convenient.
3. Because the slings of the upper suspension system, the front end lower suspension system and the rear end lower suspension system are all flexible rigging, the damage of the sling to the cabin can be effectively reduced.
