Description

Prefabricated mounting platform of mountain region wind farm blade

Technical Field

The utility model relates to the technical field of wind farm blade installation, in particular to a mountain wind farm blade prefabricated installation platform.

Background

With the progress of scientific technology, wind energy resources are increasingly paid attention to and widely developed and applied, wherein wind power generation is one of the most mature technology in wind energy utilization, the most large-scale development condition and the commercialized development prospect, the wind energy resources of a plurality of mountains and hills are extremely abundant, and the wind energy resources are high-quality resources for building wind power stations.

Before the butt joint construction of the fan tower barrel and the blades, the stud bolts of the blades are installed in the bolt holes of the blade butt joint, and meanwhile, molybdenum disulfide needs to be smeared outside each stud bolt, so that the prefabricated installation platform of the blades of the mountain wind power plant needs to be used.

At present, current mountain region wind-powered electricity generation field blade prefabrication mounting platform, when carrying out the blade installation, the staff need stand on supporting the diaphragm and operate, the later stage can be through the cylinder with supporting the diaphragm and go up and down the operation, can cause the staff who stands on supporting the diaphragm to stand unstably like this and even fall from higher supporting the diaphragm, the protectiveness of mountain region wind-powered electricity generation field blade prefabrication mounting platform on the staff stand on supporting the diaphragm when carrying out the work has been reduced, moreover, current mountain region wind-powered electricity generation field blade prefabrication mounting platform, because the base is mostly high short, again because the handrail can not carry out altitude mixture control to different staff's heights, when removing, the staff can only bend the waist and hold the handrail and carry out mobile device wholly, the health is very uncomfortable during the removal, the application scope of handrail on the prefabricated mounting platform of mountain region wind-powered electricity generation field blade has been greatly reduced.

For example, chinese patent publication No. CN213498908U discloses a prefabricated mounting platform for mountain wind farm blades, which comprises a base, armrests and brake wheels, wherein the armrests are respectively arranged on two sides of the base, the brake wheels are respectively arranged on two ends of the bottom of the base, a positioning groove is arranged in the middle position of the base, and a lifting type safety positioning mechanism is arranged in the positioning groove.

The concrete use principle of the prefabricated installation platform for the mountain wind farm blade is that,

1. moving the device to the position of the blade butt joint of the nearby fan, before starting the air cylinder, drawing out the plugboard on each group of clamping boards, and vertically placing the plugboard in the positioning semicircular groove; starting the cylinder, enabling the positioning circular ring and the positioning semicircular groove to rise to the position aligned with the opposite joint of the fan blade, then moving the device again, enabling the positioning circular ring to be positioned inside the opposite joint of the fan blade, enabling the positioning semicircular groove to be positioned outside the opposite joint of the fan blade, and locking the brake wheel to brake at the moment;

2. the staff stands on the base, can place a backing plate that has a take the altitude at the constant head tank front end, and in the staff's foot stepped on the backing plate gets into the location semicircle inslot, when installing double-headed nut, there are two kinds of working methods, (1) first method is: firstly, inserting the touch stud into the corresponding hole by a worker, stepping on a clamping plate with a required height by one foot by the worker, holding the bracelet by one hand, and installing the stud by the other hand; when the method is operated, all the plugboards are required to be placed on the supporting transverse plates at the two ends of the positioning semicircular groove, so that the work of workers is prevented from being influenced, and the second method is as follows: inserting plugboards on the corresponding clamping boards according to the positions for installing the stud bolts, and enabling workers to stand on the plugboards to start the installation work of the stud bolts; the staff can quickly stand on the plugboard through other clamping boards and hand rings;

3. after the blade is mounted on the interface bolt, the front end of the middle-upper bolt is coated with molybdenum disulfide, and when a worker coats molybdenum disulfide, the worker needs to stand on the plugboard to coat; after the painting is finished, the staff comes out of the positioning circular ring, stands on the ground, removes the device through the handrail, and descends the device into the positioning groove through the air cylinder;

4. for the installation of the blade to the stud bolts at the middle and lower parts of the interface, the method is as follows: removing the device, and enabling a worker to stand on the ground to mount the stud bolts at the middle and lower parts of the blade pair interface; after the installation of the middle and upper stud bolts is finished, a worker lies down in the positioning semicircular groove, and installs the stud bolts at the joint and smears molybdenum disulfide on the blade below the positioning semicircular groove (below the two supporting transverse plates); for the middle and lower parts of the blade butt joint (the positions which are easily contacted by staff), the staff can also directly connect the station to the base for installing and smearing the stud bolts;

5. for the installation of the bolt at the position of the blade butt joint opening corresponding to the inner sides of the two supporting plates, after the upper part and the lower part of the blade butt joint opening are completely installed by a worker, the ground worker moves the device to separate the inner sides of the two supporting plates from the position of the corresponding blade butt joint opening, then the worker stands on the plugboard or the supporting transverse plate to install the stud at the position, and the stud end is smeared with molybdenum disulfide.

According to the scheme disclosed in the prior patent document, the protection performance of workers standing on the supporting transverse plate on the mountain wind power plant blade prefabricated installation platform is low, in addition, the application range of handrails on the mountain wind power plant blade prefabricated installation platform is low, and the problem is ubiquitous and needs to be improved urgently.
