Description

Technical Field

[0001] This utility model relates to the technical field of wind turbine tower construction equipment, specifically to an auxiliary installation platform for a precast concrete wind turbine tower. Background Technology

[0002] When using precast concrete cylinder walls to construct wind turbine towers, further operations are required on the inner walls of the tower after each section is hoisted. To facilitate construction, a support platform must be erected inside the tower. However, due to the maturity of precast concrete wind turbine tower technology, the overall height of the tower is increasing, and the inner diameter gradually decreases from bottom to top. This makes directly erecting a support platform extremely costly and inefficient due to the cumbersome procedures. To address these issues, it is necessary to design an auxiliary installation platform that can be used in conjunction with the construction of precast concrete wind turbine tower modules. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an auxiliary installation platform for precast concrete wind turbine towers, so as to solve the problem that the current assembly of precast concrete wind turbine towers requires the construction of a support platform inside the tower, resulting in high overall construction costs and low work efficiency.

[0004] To solve the above problems, this utility model provides the following technical solution:

[0006] Preferably, the main worktable has a structure similar to a cylindrical disk; when the first extension arm is in the retracted state, the main worktable and the first extension arm can be lifted out together from the top of the precast concrete tower.

[0007] Preferably, there are two sets of lifting heads, which are respectively set on two perpendicular straight lines on the top surface of the main workbench near their edges; each set of lifting heads has two heads, and the axes of the corresponding hanging holes on the two heads are perpendicular to each other.

[0008] Preferably, an insertion hole is provided on the peripheral end face of the main worktable; the insertion hole extends radially along the main worktable; the fixed end of the first extension arm is installed in the insertion hole.

[0009] Preferably, the first extension arm is a segmented telescopic structure made of at least three sets of square steel with different diameters nested together; positioning holes and locking holes are opened on the square steel; the extension arm limits its extension length by arranging positioning pins at the locking holes between the square steel; the reinforcing pole is detachably installed at the positioning holes.

[0010] Furthermore, the reinforcing pole is a segmented straight rod component with telescopic extension at both ends; through holes corresponding to the positioning holes are opened on the extended ends on both sides of the reinforcing pole, and the reinforcing pole and the first extension arm are connected by pins at the positioning holes and through holes.

[0011] Preferably, a pair of parallel second extension arms are provided at the position corresponding to the notch at the bottom of the main workbench; a reinforcing pole is also provided between the second extension arms.

[0012] The beneficial effects of this utility model are:

[0013] This utility model designs an auxiliary installation platform for the construction of wind turbine concrete towers. It utilizes a main workbench as the main body, with a lifting head installed on the main workbench, allowing it to be stably lifted by an external crane and moved along its height within the tower's interior cavity. An opening is provided on the side of the main workbench to allow a ladder to pass through. Considering the change in the tower's inner diameter with height, this utility model also includes an extension arm on the main workbench. The radial extension and contraction of the extension arm, along with reinforcing struts on it, alters the workbench's coverage area. Furthermore, a connecting seat allows one side of the extension arm to connect to the tower's inner wall, further enhancing the stability of the entire installation platform. Workers can stand at different heights inside the tower and use the installation platform to perform other construction operations on the tower's inner wall. It is simple to operate, convenient to use, and has good safety features, making it suitable for widespread adoption in the industry. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: Example

[0018] Reference Figure 1This embodiment provides an auxiliary installation platform for a precast concrete wind turbine tower. It includes a main workbench 1; several lifting heads 2 are installed on the upper surface of the main workbench 1; a notch 3 is provided on one side of the main workbench 1; several telescopic first extension arms 4 are also provided on the main workbench 1; several reinforcing poles 5 are detachably installed between two adjacent first extension arms 4; a connecting seat 6 is installed on the extended end of the first extension arm 4 via a chain; the connecting seat 6 is detachably installed on the inner wall of the precast concrete tower. To accommodate the inner wall ladder of the wind turbine tower at the notch, it is necessary to provide the notch 3 as a passage for the vertical ladder.

[0019] In this embodiment, the connecting seat includes two opposing ear plates; a vertical plate is fixed between the ear plates; and a through hole is opened in the middle of the vertical plate as a hanging point for the tower crane hook cable.

[0020] The main worktable 1 is a cylindrical disk-like structure; when the first extension arm 4 is in the retracted state, the main worktable 1 and the first extension arm 4 can be lifted out together from the top of the precast concrete tower.

[0021] Two sets of lifting heads 2 are provided, each set positioned near the edge of one of two perpendicular straight lines on the top surface of the main workbench 1. Each set of lifting heads 2 has two heads, and the axes of the corresponding hanging holes on these two heads are perpendicular to each other. (Reference) Figure 1 In this embodiment, the four lifting heads are located at the four apex corners of a square inscribed in a concentric circle with the main workbench.

[0022] An insertion hole is provided on the peripheral end face of the main worktable 1; the insertion hole extends radially along the main worktable 1; the fixed end of the first extension arm 4 is installed in the insertion hole.

[0023] The first extension arm 4 is a segmented telescopic structure composed of at least three sets of square steel with different diameters nested together. Positioning holes and locking holes are provided on the square steel. The extension length of the first extension arm 4 is limited by positioning pins arranged at the locking holes between the square steel. The reinforcing pole 5 is detachably installed at the positioning holes. In this embodiment, a protective pad is also provided at the extended end of the first extension arm.

[0024] The reinforcing pole 5 is a segmented straight rod component with telescopic extension at both ends; through holes corresponding to the positioning holes are opened on the extended ends on both sides of the reinforcing pole 5, and the reinforcing pole 5 and the first extension arm 4 are connected by pins at the positioning holes and through holes.

[0025] At the position corresponding to the notch 3 at the bottom of the main workbench 1, a pair of parallel second extension arms 7 are also provided; a reinforcing pole 5 is also provided between the second extension arms 7.

[0026] In this embodiment, the main workbench 1 can be lifted out from the top of the tower by a crane. When using the utility model in this embodiment, it is only necessary to first place the main workbench flat on the ground corresponding to the inner cavity of the tower, and adjust the extension length of the extension arm according to the working height of the platform. Then, the main workbench is lifted from the outside of the tower by a crane and raised to the corresponding height. Then, the workers can install the connecting seat onto the inner wall of the tower to complete the installation of the support platform. After that, the workers can stand on the platform to work.
