Description

Technical Field

[0001] The invention relates to the technical field of wind turbine hoisting construction platforms, and in particular to a fall-proof wind turbine hoisting construction platform. Background Art

[0002] In the fields of energy and environmental protection, large fans can be used in energy systems such as wind energy and solar energy to generate electricity, provide ventilation and air circulation. They can also be used in environmental protection equipment such as flue gas desulfurization, flue gas denitrification, and waste gas treatment.

[0003] When hoisting large wind turbine columns, the hoisting height gradually increases as the columns are stacked. The higher the drop height, the more likely it is to be affected by external factors, such as wind. Generally, during the hoisting process, the slings will use pads and other materials to place at the bottom of the wind turbine to increase the friction of the contact surface, and then directly hoist it. However, if the wind is too strong and the column shakes, the sling connection may be detached or shifted, causing the wind turbine column to fall from a high altitude, causing casualties. Summary of the invention

[0004] The invention discloses a fall-proof wind turbine hoisting construction platform, which aims to solve the technical problem that the general hoisting connection is unstable. If the wind force is too strong and the column shakes, the sling connection may be separated or shifted, causing the wind turbine column to fall from a high altitude and cause casualties.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: The lifting of the lifting link rope is a key issue for the lifting of the lifting link rope, and the lifting of the lifting link rope is a key issue for the lifting of the lifting link rope. One end of the other inner rope is fixedly connected to a side support plate, and one side of the side support plate is fixedly connected to a second screw rod, and the screw tube is simultaneously engaged with the outside of the second screw rod; The bottom limiting mechanisms are provided with two, each of which is simultaneously connected to the bottom clamping pads located on the same side of the two slings, and the fastening mechanism is also provided with a traction mechanism; The bottom limiting mechanism comprises an outer sleeve, and the outer sleeve is fixedly connected to the bottom clamping pads located on the same side of the two slings at the same time; A plurality of oblique insertion rods are fixedly connected to an outer wall of one side of the side support plate, a plurality of oblique insertion holes are arranged on an inner wall of one side of the arc surface support block, and the plurality of oblique insertion rods are correspondingly inserted into the plurality of oblique insertion holes.

[0006] By providing a fastening mechanism, a side clamping pad and a bottom clamping pad, the fan column can be wrapped in multiple directions. In the fastening mechanism, by separating the inner rope, it can provide annular wrapping for the fan column together with the bottom rope. The first screw and the second screw are connected through the meshing connection of the screw tube, so as to realize the connection of the interface position of the inner rope, thereby reducing the risk of the column falling. When it rises to the top fixed position, the stepper motor can be remotely controlled by the remote controller to start and complete the disassembly of the inner rope, thereby reducing the difficulty of disassembly. By setting the outer sleeve, the distance between the two bottom clamping pads on the same side is limited, which can simultaneously ensure the stability of the motor column rising and reduce the risk of falling. At the same time, the oblique insertion rod is mainly used for inserting into the oblique socket for positioning, which can facilitate the alignment of the threads of the two, so that the screw tube can engage with the two synchronously faster.

[0007] In a preferred solution, the traction mechanism includes a winding rod, and the winding rod is fixedly connected to an outer wall of one side of the gear, a traction elastic rope is wound around the outer periphery of the winding rod, and one end of the traction elastic rope is connected to the sling, one end of the winding rod is fixedly connected to a circular baffle, the top end of the bearing bracket is fixedly connected to a second limiting sleeve, and the traction elastic rope passes through the second limiting sleeve; The outer walls on both sides facing each other of the arc surface support block are respectively fixedly connected with a first rubber patch and a second rubber patch, and the first rubber patch and the second rubber patch are respectively movably attached to the top of the horizontal fan column.

[0008] By providing a traction mechanism, when the first screw and the second screw are disengaged, based on the setting of the first rubber patch, a buffer can be provided for the second screw, thereby reducing the possibility of collision between the second screw and the outer wall of the column and reducing the probability of damage to the outer wall of the column. At the same time, the second rubber patch can also provide a buffering effect on the structure connected to the first screw. During the rotation of the gear, the traction elastic rope can be driven to be wound around the winding rod to increase the pulling force of the traction elastic rope on the structure connected to the first screw, thereby reducing the shaking amplitude of the second screw and the connected structure during the falling process and providing protection for the surface of the column.

[0009] In a preferred solution, the bottom clamping pad is provided with a through hole, the outer sleeve is connected to the through hole, and a plurality of first limit sleeves are fixedly connected to the outer periphery of the bottom clamping pad, and the first limit sleeves are movably sleeved outside the sling; An inner support rod is inserted into the outer sleeve, and an inner slide plate is fixedly connected to the outer wall of the inner support rod; The inner slide plate is located in the outer sleeve, and a spring is connected between the inner slide plate and the inner wall of the outer sleeve. One end of the inner support rod is fixedly connected to a first baffle. The first baffle is attached to one end of the fan column, and a clamping block is fixedly connected to an outer wall of one side of the inner support rod, and a through groove is penetrated through one end of the outer sleeve.

[0010] By providing a bottom limiting mechanism, in the bottom limiting mechanism, the distance between the two fastening mechanisms can be established based on the length of the outer sleeve, so as to avoid the two fastening mechanisms being affected by external forces and changing the distance to make the center of gravity unstable during the rising process, and further prevent the column from falling. The inner support rod can be attached to one end of the column through the first baffle plate to establish a limit between it and the outer sleeve, at least avoiding the fastening mechanism from moving to one side. When the column rises to a fixed position, the first baffle plate is rotated to allow the block to pass through the slot to retract the inner support rod.

[0011] From the above, it can be seen that a fall-proof wind turbine hoisting construction platform includes two slings and a bottom limiting mechanism, the bottom end of each sling is fixedly connected to two side clamping pads, and the bottom ends of the two side clamping pads are simultaneously connected to a bottom rope, two bottom clamping pads are movably sleeved on the bottom rope, and the two bottom clamping pads are attached to the bottom of a horizontally placed wind turbine column, the top of the side clamping pad is simultaneously connected to an inner rope, the inner rope is connected to a fastening mechanism, and the fastening mechanism includes an arc support block, one end of one of the inner ropes is connected to the arc support block, and a gasket is attached to the bottom of the arc support block, one side outer wall of the arc support block is fixedly connected to a bearing bracket, one side inner wall of the bearing bracket is fixedly connected to a first screw, and the bearing support A gear is connected to the frame, one side of the gear is fixedly connected to a stepper motor, and the stepper motor is linearly connected to a remote controller, the first screw is externally meshed with a solenoid, and the outer wall of the solenoid is equidistantly provided with a plurality of latching teeth, and the gear is meshed with the solenoid through the latching teeth; one end of the other inner rope is fixedly connected to a side support plate, and one side of the side support plate is fixedly connected to a second screw, and the solenoid is simultaneously meshed with the outside of the second screw; two bottom limit mechanisms are provided, each of which is simultaneously connected to the bottom clamping pad on the same side of the two slings, and a traction mechanism is simultaneously provided on the fastening mechanism; the bottom limit mechanism includes an outer sleeve, and the outer sleeve is simultaneously fixedly connected to the bottom clamping pad on the same side of the two slings.
