Description

Technical Field

[0001] The present invention relates to the technical field of tower barrel construction, and particularly to a construction equipment and a construction method for a wind power tower barrel. Background Technique

[0002] When a wind power tower barrel is under construction, each section of the tower barrel is first lifted and butted by means of a hoisting device, and after the butt joint is completed, it is fixed manually by workers. The tower barrel is fixed by bolt connection. In order to facilitate the construction of workers inside the tower barrel, a circular construction platform is provided at the butt joint position of each section of the tower barrel, and a fixed torque is required when twisting the bolts. Therefore, an electric wrench, a torque wrench and a pressure pump all need to be transported to the construction platform for the user to use. If a hoisting device is used to lift the electric tools, it takes a long time, and the weight of the electric equipment is large, so it is not convenient for the workers to carry the electric equipment when climbing the tower barrel.

[0003] A climbing system and a climbing hoisting system provided by the publication number CN101481069B also solve the technical problem of transporting tools. However, this prior art moves along the outside of the tower barrel in an encircling manner and finally transports the tools to the fan nacelle at the top of the tower barrel, and it cannot be applied to the transportation inside the tower barrel.

[0004] A wind turbine tower barrel automatic climbing machine provided by the publication number CN102126689B also moves along the outside of the tower barrel in an encircling manner, which solves the same technical problem as the above prior art. Summary of the Invention

[0005] The purpose of the present invention is to provide a construction equipment and a construction method for a wind power tower barrel to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A construction equipment for a wind power tower barrel includes a support frame, a base, a hydraulic motor, a linear drive mechanism, an electromagnet assembly, a scissor telescopic assembly and a load platform, wherein:

[0008] Bases are respectively rotatably installed on both sides of the support frame, and the bases are power-connected to the hydraulic motor. A linear drive mechanism is provided on the bases, and a linear drive mechanism is fixedly installed on the outside of the support frame. Electromagnet assemblies are provided on the execution components of all the linear drive mechanisms. The scissor telescopic assembly is arranged inside the support frame, and a load platform is provided on the scissor telescopic assembly, so that the load platform can move away from or close to the support frame.

[0009] Preferably, the electromagnet assembly consists of a connecting frame, an electromagnet and a torsion spring. The connecting frame is arranged on the executing component of the linear driving mechanism. The electromagnet is hinged to the connecting frame through a pin shaft, where the pin shaft is vertically arranged, and a torsion spring is arranged between the electromagnet and the connecting frame.

[0010] Preferably, the linear driving mechanism is a hydraulic cylinder.

[0011] Preferably, a support rod is provided at the telescopic end of the scissor telescopic assembly, and the support rod passes through the through hole on the support frame.

[0012] A construction method for wind power tower barrel construction includes the following steps:

[0013] S1. Set the construction equipment inside the tower barrel. At this time, the electromagnet is powered on, and then the electromagnet adsorbs on the inner wall of the tower barrel.

[0014] S2. Place the electric wrench, torque wrench, and pressure pump to be lifted on the loading platform.

[0015] S3. Then, the electromagnet on the outer side of the support frame is powered off, and then the two hydraulic motors drive the two bases to flip respectively. During the flipping process of the bases, the executing component of the linear driving mechanism extends. At this time, the support frame climbs upward. Then, the electromagnet on the outer side of the support frame is powered on, and the electromagnet on the executing component of the linear driving mechanism is powered off. Then, the two hydraulic motors drive the two bases to flip again. At this time, the linear driving mechanism flips upward, thus preparing for the subsequent climbing step.

[0016] S4. When the construction equipment stops moving with the tools at the butt joint part of the tower barrel, at this time, the construction tools are lifted to the working platform at the butt joint of the tower barrel, and the constructor can draw out the loading platform to use the tools.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] Through the cooperation of the linear driving mechanism and the electromagnet assembly, the construction equipment fits on the inner wall of the tower barrel in the present invention. The three-point support method avoids being unable to pass through the construction platform between two sections of the tower barrel while ensuring the supporting force, and the lifting is carried out by the driving method of the hydraulic motor, ensuring the lifting speed.

Specific implementation mode

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment:

[0025] Please refer to Figures 1 to 3 , the present invention provides a technical solution:

[0026] A construction equipment for wind power tower barrels includes a support frame 1, a base 2, a hydraulic motor 3, a linear drive mechanism 4, an electromagnet assembly 5, a scissor expansion and contraction assembly 6 and a load platform 7, wherein:

[0027] On both sides of the support frame 1, the bases 2 are respectively rotatably installed. The base 2 is installed through a rotating shaft, and the rotating shaft is rotatably installed on the support frame 1. The base 2 is fixedly sleeved on the rotating shaft. Thus, when the rotating shaft rotates, it will drive the base 2 to rotate synchronously. The base 2 is power-connected to the hydraulic motor 3. Specifically, the hydraulic motor 3 is installed on the support frame 1 through bolts, and the power output end of the hydraulic motor 3 is power-connected to the rotating shaft. The linear drive mechanism 4 is provided on the base 2, and a linear drive mechanism 4 is fixedly installed on the outer side of the support frame 1. Electromagnet assemblies 5 are provided on the actuating components of the linear drive mechanism 4. Thus, the linear drive mechanism 4 can drive the electromagnet assemblies 5 to extend or retract. The electromagnet assembly 5 can adsorb the tower barrel when it is in the energized state. The scissor expansion and contraction assembly 6 is arranged inside the support frame 1. The scissor expansion and contraction assembly 6 is arranged horizontally, and the load platform 7 is provided on the scissor expansion and contraction assembly 6. Then, the load platform 7 can move away from or close to the support frame 1.

[0028] As a preferred embodiment, the electromagnet assembly 5 is composed of a connecting frame 51, an electromagnet 52 and a torsion spring 53. The connecting frame 51 is arranged on the executing component of the linear driving mechanism 4. The electromagnet 52 is hinged to the connecting frame 51 through a pin shaft, and the pin shaft is vertically arranged. Thus, when the electromagnet 52 is attached to the inner wall of the tower barrel, it can flip along the circumferential direction of the inner wall of the tower barrel, so that the electromagnet 52 can be attached to the inner wall of the tower barrel, ensuring the adhesion of the construction equipment. A torsion spring 53 is arranged between the electromagnet 52 and the connecting frame 51, and thus the torsion spring 53 provides torsion for the return stroke of the electromagnet 52. In the drawings of this application, the shape of the electromagnet 52 is semi-circular, which is just one of the shape styles. The outer shape of the electromagnet 52 is not limited to this shape, and the shape style of the electromagnet 52 can be reasonably selected according to actual use requirements.

[0029] As a preferred embodiment, the linear driving mechanism 4 is a hydraulic cylinder 41. Of course, the linear driving mechanism is not limited to this, and it can also be a linear electric cylinder, a lead screw transmission pair, etc. An appropriate driving component can be selected according to actual needs.

[0030] As a preferred embodiment, a support rod 61 is provided at the telescopic end of the scissor telescopic assembly 6, and the support rod 61 passes through the through hole on the support frame 1. Thus, the scissor telescopic assembly 6 is prevented from being cantilever-supported, increasing the support force.

[0031] A construction method for wind power tower barrel construction includes the following steps:

[0032] S1, Set the construction equipment inside the tower barrel. At this time, the electromagnet 52 is energized, so the electromagnet 52 adsorbs on the inner wall of the tower barrel, and then the whole equipment is attached to the inner wall of the tower barrel in the shape of a "gecko";

[0033] S2, Place the electric wrench, torque wrench, and pressure pump to be lifted on the load platform 7, thus avoiding manual handling of electric tools;

[0034] S3, Then the electromagnet 52 arranged outside the support frame 1 is powered off, and then the two hydraulic motors 3 respectively drive the two bases 2 to flip. During the flipping process of the base 2, the executing component of the linear driving mechanism 4 extends. At this time, the support frame 1 has an upward climbing movement trend. At this time, the linear driving mechanism 4 flips downward relative to the support frame 1. Then the electromagnet 52 arranged outside the support frame 1 is energized, and the electromagnet 52 arranged on the executing component of the linear driving mechanism 4 is powered off. At this time, the support frame 1 still adsorbs on the inner wall of the tower barrel. Then the two hydraulic motors 3 drive the two bases 2 to flip again. At this time, the linear driving mechanism 4 flips upward, thus preparing for the subsequent climbing step. Repeating this step can realize the lifting of the construction equipment, and then transfer the electric tools;

[0035] S4. When the construction equipment arrives at the tower barrel docking part with the tool and stops moving, at this time, the construction tool is lifted to the working platform for tower barrel docking. The constructor can draw out the loading platform 7 and use the tool. Since the loading platform 7 is arranged on the loading platform 7, it is convenient to change the position of the loading platform 7 and convenient for the user to pick up the tool.

[0036] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
