Description

Technical Field

[0001] The utility model relates to the technical field of tower crane wall attachments, and specifically to an attachment structure for a tower crane. Background Technique

[0002] The attachment structure of a tower crane, also known as an attachment frame or attachment tie, is an important part added during high-rise construction to prevent the tower crane from being damaged by lateral shear forces. Its main principle is to connect the main part of the tower crane to the outer wall of the building, and use the outer wall to bear the horizontal force between the tower crane and the building, thereby reducing the load on the ground.

[0003] During the connection process between the attachment structure and the building wall, a water drill is usually used to drill holes and through-wall bolts are used to fix the connecting iron plate to the outer wall of the building. However, after long-term use and during stormy weather, the wind will cause an instantaneous huge stress on the attachment strut, which will cause the through-wall bolt to damage the building wall, so there is a risk of the attachment strut detaching from the wall, thus posing a safety hazard to the fixation of the tower crane standard section. Content of the Utility Model

[0004] The purpose of the utility model is to provide an attachment structure for a tower crane to solve the problem that during the connection process between the attachment structure and the building wall, a water drill is usually used to drill holes and through-wall bolts are used to fix the connecting iron plate to the outer wall of the building. However, after long-term use and during stormy weather, the wind will cause an instantaneous huge stress on the attachment strut, which will cause the through-wall bolt to damage the building wall, so there is a risk of the attachment strut detaching from the wall, thus posing a safety hazard to the fixation of the tower crane standard section.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An attachment structure for a tower crane includes two attachment frames. The two ends of the two attachment frames are in contact with each other. At both ends of the side wall of the attachment frame, a first positioning seat is fixedly connected. A first rotating block is rotatably connected in each of the two first positioning seats. An attachment column is fixedly connected to each of the two first rotating blocks. A sleeve rod is slidably sleeved outside each of the two attachment columns. A second rotating block is fixedly connected to the end of each of the two sleeve rods. A second positioning seat is rotatably connected to the outside of the second rotating block. A buffer plate is fixedly connected to the end of the second positioning seat. A U-shaped shell is slidably arranged outside the buffer plate. Two attachment wall screws are symmetrically and fixedly connected to the side wall of the U-shaped shell.

[0007] Furthermore, three top support blocks are fixedly connected at equal intervals on the opposite inner walls of the attachment frame, and an anti-slip plate is fixedly arranged on the inner side wall of the attachment frame.

[0008] Furthermore, two fixing blocks are symmetrically and fixedly connected to both ends of the attachment frame body, and two mounting bolts are symmetrically screwed and connected in the fixing blocks.

[0009] Furthermore, a plurality of adjusting holes are equidistantly arranged on the attachment column, and two positioning bolts that are screwed and sleeved with the adjusting holes are inserted at the top of the sleeve rod.

[0010] Furthermore, limiting grooves are arranged on the opposite inner walls of the C-shaped shell, a limiting slider fixedly connected to the buffer plate is slidably connected in the limiting groove, two dampers fixedly connected to the C-shaped shell are symmetrically and fixedly arranged on the side wall of the buffer plate, and a damping spring fixedly connected to the buffer plate is sleeved outside the damper.

[0011] Furthermore, an attachment wall abutting plate that abuts against the wall body is sleeved outside the attachment wall screw, four reinforcing strips are symmetrically and fixedly arranged on the inner wall of the attachment wall abutting plate, and a fixing nut is screwed and connected to the outside of the attachment wall screw.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. By splicing two attachment frame bodies together to form a complete attachment frame, and tightly surrounding this attachment frame and the standard section of the tower crane, and by providing telescopic attachment columns at both ends of the side wall of the attachment frame body, the length of the attachment column in the sleeve rod can be adjusted, so that the standard section can be attached to building walls at different horizontal distances. By connecting the attachment columns to the wall on both sides and both ends of the attachment frame body, the attachment strength of the tower crane can be increased. By fixing two attachment wall screws passing through the building wall on the side wall of the C-shaped shell, and using the fixing nut to be screwed and connected with the attachment wall screw to abut the attachment wall abutting plate against the inner wall of the wall, the stress area of the attachment wall screw on the wall is increased, so that the attachment wall screw can be prevented from pulling the wall during long-term use and in strong wind weather.

[0014] 2. By slidably connecting a buffer plate in the C-shaped shell, and fixedly connecting two dampers and damping springs to the side wall of the buffer plate, when encountering strong wind weather, the buffer plate, dampers and damping springs can buffer the end of the attachment column and the attachment frame, which is beneficial to reducing the instantaneously increased stress, avoiding damage to the attachment components, and improving the service life of the attachment structure.

Specific implementation manner

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 6 , in the embodiment of the present utility model, an attachment structure of a tower crane includes two attachment frames 101. The two ends of the two attachment frames 101 are in contact with each other. Both ends of the side wall of the attachment frame 101 are fixedly connected with first positioning seats 102. A first rotating block 201 is rotatably connected in each of the two first positioning seats 102. An attachment column 202 is fixedly connected to each of the two first rotating blocks 201. A sleeve rod 204 is slidably sleeved outside each of the two attachment columns 202. A second rotating block 206 is fixedly connected to the end of each of the two sleeve rods 204. A second positioning seat 308 is rotatably connected outside the second rotating block 206. A buffer plate 306 is fixedly connected to the end of the second positioning seat 308. A C-shaped shell 301 is slidably arranged outside the buffer plate 306. Two wall-attached screws 303 are symmetrically and fixedly connected to the side wall of the C-shaped shell 301; a wall-attached backplate 401 that abuts against the wall is sleeved outside the wall-attached screw 303. Four reinforcing strips 402 are symmetrically and fixedly arranged on the inner wall of the wall-attached backplate 401. A fixing nut 403 is screwed on the outside of the wall-attached screw 303.

[0024] Specifically, two attachment frames 101 can be spliced together to form a complete attachment frame, and this attachment frame can closely surround the standard section of the tower crane. By providing telescopic attachment columns 202 at both ends of the side wall of the attachment frame body 101, the length of the attachment column 202 in the sleeve rod 204 can be adjusted, so that the standard section can be attached to building walls at different horizontal distances. By providing attachment columns 202 at both ends of both sides of the attachment frame body 101 to connect with the wall, the attachment strength of the tower crane can be increased. By fixing two wall attachment screws 303 passing through the building wall on the side wall of the C-shaped shell 301, and using a fixing nut 403 to be screwed and connected with the wall attachment screw 303, the wall attachment plate 401 can be abutted against the inner wall of the wall, thereby increasing the force-bearing area of the wall attachment screw 303 on the wall, and preventing the wall attachment screw 303 from pulling the wall during long-term use and in strong wind weather.

[0025] Embodiment 1

[0026] As Figure 3 shown, in this embodiment, three top support blocks 103 are fixedly connected at equal intervals on the opposite inner walls of the attachment frame body 101, and an anti-slip plate 104 is fixedly arranged on the inner side wall of the attachment frame body 101; two fixing blocks 105 are symmetrically and fixedly connected at both ends of the attachment frame body 101, and two mounting bolts 106 are symmetrically screwed and connected in the fixing blocks 105.

[0027] In this embodiment, by providing top support blocks 103 on the inner wall of the attachment frame body 101, they can抵触 the outer wall of the standard section, and the anti-slip plate 104 can increase the friction with the tower crane. Then, the mounting bolts 106 are used to connect the fixing blocks 105 at both ends of the two attachment frame bodies 101, so that the two attachment frame bodies 101 can be quickly spliced into a complete attachment frame.

[0028] Embodiment 2

[0029] As Figure 5 shown, in this embodiment, a plurality of adjustment holes 203 are equidistantly opened on the attachment column 202, and two positioning bolts 205 that are screwed and sleeved with the adjustment holes 203 are inserted at the top of the sleeve rod 204; limiting grooves 302 are opened on the opposite inner walls of the C-shaped shell 301, and limiting sliders 307 fixedly connected with the buffer plate 306 are slidably connected in the limiting grooves 302. Two dampers 304 fixedly connected with the C-shaped shell 301 are symmetrically fixedly arranged on the side wall of the buffer plate 306, and a damping spring 305 fixedly connected with the buffer plate 306 is sleeved outside the damper 304.

[0030] In specific implementation, a buffer plate 306 is slidably connected in the U-shaped shell 301, and two dampers 304 and damper springs 305 are fixedly connected to the side wall of the buffer plate 306. Therefore, when encountering strong wind weather, the buffer plate 306, the dampers 304 and the damper springs 305 can buffer the end of the attachment column 202 and the attachment frame, thereby helping to reduce the instantaneously increased stress, avoiding damage to the attachment assembly, and improving the service life of the attachment structure.
