Description
Technical Field
[0001] This invention belongs to the field of wind turbine tower docking construction technology, and more specifically, relates to a device for wind turbine tower docking construction. Background Technology
[0002] When developing wind power in low-to-medium wind speed areas on land, large-diameter, tall towers are generally required to capture more wind energy. If a 6-meter diameter tower is used as a single structure, it exceeds the size limits of conventional road and rail transport, and is even more difficult to pass through mountainous areas with complex road conditions. By adopting a segmented design with multiple connecting sections, the entire tower can be disassembled into multiple arc-shaped lobes. The size and weight of each section are suitable for standard transport vehicles, eliminating the need for special transport. This can significantly reduce transportation costs and shorten the transportation cycle, making it the mainstream technical solution to solve the transportation problem of large-diameter towers. Therefore, hoisting structures are required during the construction of wind turbine tower connections.
[0003] Currently, the following problems still exist in the hoisting process of wind turbine towers: 1. When the hoisting structure is not accurately connected to the wind turbine tower, it is not easy for construction personnel to know, which makes it easy for the wind turbine tower to fall off during subsequent hoisting; 2. There is a lack of automatic warning and alarm structure, which cannot continuously emit alarm sounds during the hoisting process of the wind turbine tower, which is not conducive to warning construction personnel near the wind turbine tower. Summary of the Invention
[0004] This disclosure relates to a device for the installation of wind turbine towers, comprising a tower hoisting unit, a control and detection unit, a connection and positioning unit, an activity limit unit, and a hoisting warning unit. When the right-side connection and positioning rod is not properly connected to the connection and positioning frame, the inner sides of the four circular detection plates, under the action of four helical springs a, contact the inner sides of the two arc-shaped hoisting frames, causing the two arc-shaped hoisting frames to automatically detach from the wind turbine tower to be hoisted. This facilitates the construction personnel's awareness that the right-side connection and positioning rod is not properly connected to the connection and positioning frame. When the two control switches are in the on state, the two warning alarms continuously emit warning alarm sounds, alerting nearby construction personnel. This solves the problems of construction personnel not being able to be aware when the hoisting structure is not accurately connected to the wind turbine tower and the inability to continuously emit alarm sounds during the hoisting of the wind turbine tower.

[0011] In at least some embodiments, the movable limiting unit further includes: a circular anti-detachment plate a and a helical spring b; the circular anti-detachment plate a is fixedly installed outside the movable limiting pin, and the bottom of the circular anti-detachment plate a contacts the connecting positioning frame; the helical spring b is sleeved outside the movable limiting pin, and the helical spring b is located between the movable limiting seat and the circular anti-detachment plate a.
[0012] In at least some embodiments, the hoisting warning unit includes: a tower detection rod, a circular anti-detachment plate b, and a circular anti-detachment plate c; the tower detection rod is slidably mounted on a connecting positioning rod, and the bottom end of the tower detection rod is provided with rounded corners; the circular anti-detachment plate b is fixedly mounted on the top end of the tower detection rod, and the bottom of the circular anti-detachment plate b is in contact with the connecting positioning rod; the circular anti-detachment plate c is fixedly mounted on the outside of the tower detection rod, and the circular anti-detachment plate c is located below the connecting positioning rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, since two control and detection frames are slidably installed on two arc-shaped hoisting frames, and four rubber anti-slip sleeves are fixedly installed on the outside of the two control and detection frames, it is convenient for construction personnel to control the position of the two arc-shaped hoisting frames through the four rubber anti-slip sleeves, which is beneficial for the connection between the two arc-shaped hoisting frames and the wind turbine tower to be hoisted; and since two hoisting connection plates are fixedly installed on the top of the two arc-shaped hoisting frames, it is convenient for the hooks on the external hoisting machinery to be connected. Furthermore, since the four circular detection plates are fixedly installed on the inner side of the two control detection frames, the four circular detection plates have a sliding effect; and since the four helical springs a are sleeved on the outside of the two control detection frames, and the four helical springs a are located between the two arc-shaped hoisting frames and the four circular detection plates, the four helical springs a can be compressed when the four circular detection plates are subjected to force.
[0016] 2. In this invention, since the two connecting positioning rods are fixedly installed on the two hoisting connecting plates, and the connecting positioning frame is fixedly installed on the left connecting positioning rod, and the right connecting positioning rod is inserted into the right end of the connecting positioning frame, the two hoisting connecting plates are connected; and since the movable limiting pin is slidably installed on the movable limiting seat and the connecting positioning frame, and the bottom end of the movable limiting pin is inserted into the right connecting positioning rod, and the bottom of the movable limiting pin is chamfered, the two connecting positioning rods can be firmly connected to the two connecting positioning frames; Furthermore, when the connecting positioning rod on the right is not connected to the connecting positioning frame, the inner sides of the four circular detection plates contact the inner sides of the two arc-shaped hoisting frames under the action of the four helical springs a, causing the two arc-shaped hoisting frames to automatically detach from the wind turbine tower to be hoisted. This helps construction personnel to know that the connecting positioning rod on the right is not connected to the connecting positioning frame. Also, because the circular anti-detachment plate a is fixedly installed outside the movable limit pin, and the helical spring b is sleeved outside the movable limit pin, and the helical spring b is located between the movable limit seat and the circular anti-detachment plate a, it plays an elastic positioning role for the movable limit pin, preventing the movable limit pin from falling off.
[0017] 3. In this invention, because the two tower detection rods are slidably installed on the two connecting positioning rods, and the two helical springs c are sleeved on the outside of the two tower detection rods, and the two helical springs c are located between the two connecting positioning rods and the two circular anti-detachment plates c, they play an elastic positioning role for the two tower detection rods. Under normal conditions, the two tower detection rods will not slide arbitrarily; when the two arc-shaped hoisting frames are connected to the wind turbine tower, the wind turbine tower can push the two tower detection rods to slide upward a certain distance. Furthermore, since the two control switches are fixedly installed inside the two tower detection rods, and the two pressing protrusions are fixedly installed outside the two control switches, when the wind turbine tower pushes the two tower detection rods to slide upward a certain distance, the two connecting positioning rods can push the two pressing protrusions to move inward, so that the two control switches are in the open state; and since the two lithium batteries are electrically connected to the two warning alarms, and the two control switches are electrically connected to the two lithium batteries and the two warning alarms, when the two control switches are in the open state, the two warning alarms will continuously emit warning alarm sounds, which can alert nearby construction personnel.
