[0001] The present invention relates to the technical field of installation of crown dampers, and particularly relates to an auxiliary device for installing a crown damper. Background Art

[0002] A crown damper is a device used to reduce the dynamic load generated by natural wind on a building. By setting special dampers in the tower body, the damping ratio of the structure is increased, thereby reducing the amplitude of the structure and controlling its vibration. The main functions of the crown damper include weakening vibration, reducing wind-induced fatigue damage, enhancing wind resistance, etc. Dampers at the crown positions of super high-rise towers are mostly very large. To avoid the damper from swaying and colliding with the surrounding structures during hoisting and installation, auxiliary devices are required to assist in installing the damper to avoid collisions, which increases the safety and civilization degree of on-site construction.

[0003] The prior art has the following deficiencies: When the existing installation auxiliary device installs the damper, it cannot stably support and buffer the swaying of the damper in different directions. As a result, the damper is prone to collide with the inner wall of the crown during installation, which will affect the safety of the damper installation process. At the same time, the collision will affect the service life of the damper and the crown. Summary of the Invention

[0004] The purpose of the present invention is to provide an auxiliary device for installing a crown damper. By two limiting plates, the suspension ropes of the crane can be limited, so that the suspension ropes can stably hoist the damper. At the same time, the setting of the bowl-shaped support pad and the moving rod can support and buffer the swaying of the damper, and can avoid the damper from colliding with the crown structure, so as to solve the above-mentioned deficiencies in the technology.

[0031] The present invention provides an installation auxiliary device for a tower crown damper as shown in Figure 1 Figure, which includes a limiting mechanism 1 arranged outside the tower crane sling and used for limiting the sway of the sling;

[0032] There are four supporting mechanisms 2, which are respectively arranged at both ends of the bottom of the damper and used for supporting and buffering the damper;

[0033] There are four anti-collision mechanisms 3, which are respectively arranged at the top and bottom of both ends of the damper and used for buffering the sway of the damper.

[0034] In order to keep the sling stable during the hoisting process, as shown in Figure 1-3 Figure, the limiting mechanism 1 includes two limiting plates 102. The inner walls of the two limiting plates 102 are both fixedly installed with first built-in springs 103. One end of each of the two first built-in springs 103 away from the limiting plate 102 is fixedly installed with a buffer pad 104. A cable 101 is fixedly installed between the opposite ends of the two limiting plates 102 and the inner wall of the tower crown. The limiting plates 102 can be installed and fixed through the cable 101. The two limiting plates 102 can limit the sling. The first built-in springs 103 and buffer pads 104 inside the limiting plate 102 can buffer the kinetic energy of the sway of the sling, which can ensure the stability of the sling and enable the sling to stably hoist the damper.

[0035] In order to avoid collision between the damper and the tower crown structure during the installation process, as shown in Figure 1 and Figures 6-7As shown in the figure, the anti-collision mechanism 3 includes a fixed sleeve 301 installed on the inner wall of the tower crown. A buffer spring 303 is fixedly installed on the inner wall of the fixed sleeve 301. One end of the buffer spring 303 away from the inner wall of the fixed sleeve 301 is fixedly installed with a moving rod 304. A bowl-shaped support pad 306 is fixedly sleeved on the outer side of the end of the moving rod 304 away from the fixed sleeve 301. The bowl-shaped support pad 306 can buffer the damper, enabling the moving rod 304 to move along the inner wall of the fixed sleeve 301. At the same time, the buffer spring 303 can buffer the movement of the moving rod 304, thereby avoiding the left and right shaking of the damper and the collision with the tower crown structure, ensuring the stability of the damper installation process, and prolonging the service life of the damper and the tower crown structure.

[0036] To avoid the shaking of the damper, as Figure 1 and Figures 4-5 shown, the support mechanism 2 includes support rods 201. The four support rods 201 are respectively fixedly installed on both sides of the two ends of the inner bottom of the tower crown. Support springs 202 are fixedly installed at the bottoms of the inner walls of the support rods 201. A movable rod 203 is fixedly installed at the top of the support spring 202. A traction rope 204 is fixedly installed at the top of the movable rod 203. A connection ring 205 connected to the damper is fixedly installed at the top of the traction rope 204. The movable rod 203 is connected to the damper through the connection ring 205 and the traction rope 204. When the damper shakes, the movable rod 203 moves along the inner wall of the support rod 201 under the action of the traction rope 204. The support spring 202 can support and buffer the movement of the movable rod 203, thereby reducing the shaking of the damper and keeping it stable during the hoisting process.

[0037] To facilitate the installation and fixation of the anti-collision mechanism 3 according to the inclination angle of the tower crown structure, as Figure 1 and Figures 6-7 shown, the anti-collision mechanism 3 further includes a connecting ball head 302. The connecting ball head 302 is fixedly installed at the end of the fixed sleeve 301 away from the moving rod 304. An installation seat 307 is sleeved on the outer side of the connecting ball head 302. Tightening bolts 308 are equally spaced and annularly threaded and inserted into the inner wall of the outer side of the end of the installation seat 307 away from the fixed sleeve 301. The ends of the tightening bolts 308 away from the installation seat 307 are threadedly connected to the inner wall of the tower crown structure. The connection between the connecting ball head 302 and the installation seat 307 can conveniently adjust the horizontal state of the fixed sleeve 301 according to the inclination angle of the tower crown structure, enabling the bowl-shaped support pad 306 to stably support and buffer the damper.

[0038] To enable the bowl-shaped support pad 306 to stably buffer the shaking of the damper, as Figures 6-7As shown, a second built-in spring 305 is fixedly installed on the outer wall of one end of the moving rod 304 away from the fixed sleeve 301. One end of the second built-in spring 305 away from the moving rod 304 is fixedly connected to the inner wall of the bowl-shaped support pad 306. The second built-in spring 305 can support and buffer the bowl-shaped support pad 306, so that the bowl-shaped support pad 306 can stably support and buffer the damper, avoiding collisions between the damper and the inner wall of the tower crown structure, thereby ensuring the safety of the damper installation process and extending the service life of the damper and the tower crown structure.

[0039] In order to enable the two limiting plates 102 to be closely connected, as Figures 1-3 shown, the limiting mechanism 1 further includes two connecting plates 105. The two connecting plates 105 are respectively arranged at the top and bottom of the outer wall of one side of the connection position of the two limiting plates 102. Fixed rods 106 penetrating the inner walls of the two limiting plates 102 are fixedly installed at both ends of one side of the connecting plate 105. Fixing plates 107 are movably sleeved on the outer sides of the ends of the two fixing rods 106 at the same height away from the connecting plate 105. Connecting bolts 108 are threadedly inserted into the inner walls of the ends of the fixing rods 106 away from the connecting plate 105. The screw head portions of the connecting bolts 108 are in contact connection with the outer walls of the fixing plates 107. The two limiting plates 102 can be connected by the two connecting plates 105 and the four fixing rods 106. At the same time, through the threaded connection between the connecting bolts 108 and the inner walls of the fixing rods 106 and the contact connection with the outer walls of the fixing plates 107, the connecting plates 105 and the fixing plates 107 can stably connect and fix the two limiting plates 102, avoiding loosening and falling off of the connection between the two limiting plates 102, so that the limiting mechanism 1 can stably limit the sling.

[0040] When installing the damper, the four support rods 201 are fixed to the inner bottom of the tower crown structure, and then the connecting ring 205 is connected to the damper. At the same time, the four mounting seats 307 are installed to the top and bottom of the inner walls at both ends of the tower crown structure. Then, the fastening bolts 308 are used to penetrate the inner wall of the mounting seat 307 and are threadedly connected to the inner wall of the tower crown structure. At the same time, the fixing sleeve 301 can be easily adjusted to a horizontal state by rotating the connecting ball head 302, so that the bowl-shaped support pad 306 can contact the outer wall of the suspended damper. Then, the two limiting plates 102 can be connected through the connection between the steel cable 101 and the tower crown structure. Install and fix, then install the two connecting plates 105 to the top and bottom of the outer wall on one side of the connecting position of the two limiting plates 102, and make the four fixing rods 106 pass through the inner walls of the two limiting plates 102, then sleeve the fixing plate 107 to the outer wall of one end of the two fixing rods 106 at the same height away from the connecting plate 105, then use the connecting bolt 108 to pass through the inner wall of the fixing plate 107 and thread it with the inner wall of the fixing rod 106, and make the screw head part of the connecting bolt 108 contact and connect with the outer wall of the fixing plate 107, so that the two limiting plates 102 are tightly connected and can be placed on the outside of the sling;

[0041] When the damper shakes, the buffer pad 104 can shrink toward the inner wall of the limiting plate 102 under the shaking action of the sling, and then drive the two first built-in springs 103 to extend or shrink, and then the kinetic energy of the sling shaking can be buffered by the first built-in spring 103 and the buffer pad 104, so as to avoid the sling shaking when the damper is hoisted, and at the same time, the second built-in spring 305 on the inner wall of the bowl-shaped support pad 306 can buffer the bowl-shaped support pad 306, and at the same time, the moving rod 304 moves along the inner wall of the fixed sleeve 301, and the buffer spring 303 can buffer it, and then the shaking of the damper can be buffered. At the same time, the shaking of the damper can be supported by the movement of the movable rod 203 along the inner wall of the support rod 201. The movement of the movable rod 203 can be supported and buffered by the support spring 202, and then the shaking of the damper can be supported and buffered, so that the damper can remain stable during the lifting process, and the safety of the damper during the installation process can be ensured. This embodiment specifically solves the problem in the prior art that the damper is prone to collide with the tower crown structure due to shaking, which will affect the safety of the installation process.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
