Description

Technical Field

[0001] The invention relates to the technical field of tower crane installation equipment, in particular to a wall-attached structure of an external climbing tower crane. Background Art

[0002] In the construction of high-rise buildings, tower cranes play a vital role as the main vertical transportation and hoisting equipment. Due to their towering structure and huge hoisting capacity, tower cranes need to maintain stability and safety during operation. However, as the height of the building increases, the height of the tower crane itself is also increasing. After a certain height, it is difficult to meet the stability requirements by simply relying on the support of its foundation. Therefore, a wall attachment device is needed to fix the tower body to the building to prevent the tower body from shaking or tipping over.

[0003] When installing the wall attachment mechanism in the prior art, it is necessary to first pass the fixing bolts through the wall of the building body, and then install the load-bearing plate and the compression nut on the indoor side. This installation method is not only cumbersome to operate, but also causes certain damage to the building wall structure. Since the fixing bolts need to pass through the wall, it not only destroys the integrity of the wall, but also may affect the load-bearing and seismic performance of the wall. When the wall attachment mechanism is subjected to external forces, such as wind force, hoisting load, etc., since the wall structure has been damaged, it is easy to cause cracks and other phenomena.

A first docking plate 22 and a second docking plate 23 are provided on both sides of the mounting seat 21. A fixing plate 25 is provided at one end of each of the first docking plate 22 and the second docking plate 23.

[0037] A locking pin 3, the locking pin 3 is used to install the wall attachment structure on one side of a building 6, the locking pin 3 is a plurality of and includes a female pin 31 and a sub-pin 32, the female pin 31 is arranged on one side of the fixing plate 25, the building 6 includes a wall 61, a plurality of mounting holes 62 are opened on the surface of the wall 61, and the inner cavity of the mounting hole 62 is provided with the female pin 31;

[0038] A rotating shaft is provided at one end of the first docking plate 22 and the second docking plate 23 connected to the mounting seat 21, and two driven sprockets 216 are provided on the inner wall of the mounting seat 21. The two driven sprockets 216 are respectively fixedly connected to the rotating shaft, and a worm 211 is also provided on the inner wall of the mounting seat 21 for driving the two driven sprockets 216 to rotate in opposite directions.

[0039] In this embodiment, please refer to Figure 4 , Figure 6 The inner wall of the mother pin 31 is provided with an anti-slip block 311, the inner cavity of the sub-pin 32 is provided with a locking rod 321, the outer side of the locking rod 321 is provided with a spiral pattern, the inner wall of the mother pin 31 is provided with spiral grooves that match each other, one end of the locking rod 321 is provided with an anti-slip bead 322, the middle section of the sub-pin 32 is provided with a regulating ring 323, the inner cavity of the regulating ring 323 is provided with an embedding groove 324, and the embedding groove 324 is mutually adapted with one side of the anti-slip block 311. In this embodiment, by controlling the rotation of the sub-pin 32, and because the locking rod 321 cooperates with the inner cavity thread of the mother pin 31, by controlling the rotation of the locking rod 321, it enters the inner cavity of the mother pin 31, when When the anti-slip bead 322 enters the rear of the anti-slip block 311, the regulating ring 323 moves to the outer position of the anti-slip block 311, and the anti-slip block 311 enters the inner cavity of the embedding groove 324. At this time, by controlling the regulating ring 323 to rotate, the anti-slip block 311 can be disengaged from the inner cavity of the embedding groove 324, so that the anti-slip block 311 moves forward under the thrust of the regulating ring 323. At this time, the anti-slip bead 322 has moved to the rear of the anti-slip block 311. When the anti-slip block 311 moves forward, the anti-slip bead 322 is blocked, and the anti-slip bead 322 can be prevented from falling out of the inner cavity of the mother pin 31, thereby preventing the connection between the mother pin 31 and the child pin 32 from being disconnected.

[0040] In this embodiment, please refer to Figure 5The outer side of the driven sprocket 216 is connected and meshed with a chain 215, and the inner walls of the two chains 215 are provided with different tooth shapes, that is, when the two chains 215 rotate in the same direction, the two driven sprockets 216 will be driven to rotate in different directions. The other side of the inner wall of the chain 215 is meshed with a driving sprocket 214, and the corresponding surfaces of the two driving sprockets 214 are connected by a connecting rod 213. In this embodiment, the two driving sprockets 214 are driven to rotate by controlling the connecting rod 213 to rotate, and the two chains 215 are driven to rotate by the driving sprocket 214. The two driven sprockets 216 are driven to rotate in opposite directions by the rotation of the chain 215, so that the rotating shaft connected to the driven sprockets 216 rotates in different directions, so that the first docking plate 22 and the second docking plate 23 are brought closer to or separated from each other, so as to adjust the position of the fixing plate 25, so that the connection position of the sub-pin 32 and the mother pin 31 can be flexibly adjusted according to factors such as the area and environment of the building wall.

[0041] In this embodiment, please refer to Figure 5 A worm wheel 212 is provided in the middle of the connecting rod 213, and the outer side of the worm wheel 212 is meshed with the worm 211. In this embodiment, the worm 211 and the worm wheel 212 are provided, and the two rotating shafts are driven to rotate in different directions by the worm 211. Due to the characteristics of the worm 211 and the worm wheel 212, the rotation of the worm wheel 212 can only be controlled by the worm 211, and the worm wheel 212 cannot drive the worm 211 to rotate. Therefore, after the position of the fixed plate 25 is adjusted, the stability of the position of the female pin 31 can be ensured.

[0042] In this embodiment, please refer to Figure 6 The bolt assembly 326 is used to connect the adjusting ring 323 and the reinforcing block 325, so that the adjusting ring 323 and the reinforcing block 325 can be connected together.

[0043] In this embodiment, please refer to Figure 46, the side of the anti-slip block 311 facing the sub-pin 32 is set as an inclined surface, and the inner wall of the embedding groove 324 is provided with a magnetic ring, which is used to attract the anti-slip block 311 to make it enter the inner cavity of the embedding groove 324. In this embodiment, by setting one side of the anti-slip block 311 as an inclined surface, when the anti-slip bead 322 enters the inner cavity of the mother pin 31, the anti-slip block 311 can be pushed to move backward. At the same time, since the other side of the anti-slip block 311 is not set as an inclined surface, the sub-pin 32 can be effectively prevented from falling off the inner cavity of the mother pin 31. At the same time, since a magnetic ring is provided in the inner cavity of the embedding groove 324, when the embedding groove 324 is moved to the corresponding position of the anti-slip block 311 by rotating the regulating ring 323, the anti-slip block 311 can be moved backward into the inner cavity of the embedding groove 324. At this time, the connection between the mother pin 31 and the sub-pin 32 can be conveniently disconnected, thereby facilitating the disassembly of the wall-mounted structure.

[0044] In this embodiment, please refer to Figure 7 , Figure 8 A fixing cap 315 is provided at one end of the female pin 31, and a plurality of second movable grooves 316 are provided on the outer side of the fixing cap 315. A pressure plate 317 is provided in the inner cavity of the second movable groove 316. One side of the pressure plate 317 is provided as an inclined surface, and a gear 318 is provided on the other side of the pressure plate 317. A plurality of first movable grooves 312 are provided on the outer side of the female pin 31, and a movable plate 313 is provided in each first movable groove 312. The movable plate 313 can slide in the first movable groove 312, and a rack 314 is provided on one side of the movable plate 313. The rack 314 meshes with the outer side of the gear 318. In this embodiment, after the locking pin 3 completes the connection, under the influence of external force, when the female pin 31 moves toward the entrance direction of the mounting hole 62, the inclined surface of the pressure plate 317 is squeezed with the inner wall of the mounting hole 62, causing the pressure plate 317 to move backward, thereby driving the gear 318 to move backward, and because the outer side of the gear 318 is meshed with one side of the rack 314, the rack 314 drives the movable plate 313 to move outward, allowing the movable plate 313 to penetrate deeper into the inner cavity of the pressure-resistant groove 622, thereby making the connection between the female pin 31 and the mounting hole 62 more stable, thereby improving the connection force of the wall-mounted structure.

[0045] In this embodiment, please refer to Figure 8 The inner wall of the mounting hole 62 is provided with pressure-resistant grooves 622 having the same number as the movable plates 313, and a reinforcement ring 621 is provided at the entrance of the mounting hole 62. The aperture of the reinforcement ring 621 is smaller than the diameter of the fixing cap 315. In this embodiment, by providing the pressure-resistant grooves 622, when multiple movable plates 313 move outward at the same time, they penetrate deeper into the inner cavity of the pressure-resistant grooves 622, thereby preventing the female pin 31 from being disconnected from the building 6 under the influence of external force. At the same time, by providing the reinforcement ring 621, the female pin 31 is further prevented from being detached from the mounting hole 62 as a whole.

[0046] In this embodiment, please refer to Figure 5 A support rod 24 is provided between the first docking plate 22 and the second docking plate 23. The length of the support rod 24 can be adjusted and locked by bolts. In this embodiment, by providing the support rod 24, when the docking position of the female pin 31 is adjusted, the length of the support rod 24 is locked by bolts to enhance the stability of the connecting seat 2.

[0047] In this embodiment, please refer to Figure 1-Figure 2 Preset ends 11 are also provided on both sides of the wall-attached frame 1, and reinforcement rods 4 can be installed on both sides of the wall-attached frame 1 through the preset ends 11. The reinforcement rods 4 are connected to the building 6 through the locking pins 3. In this embodiment, reinforcement rods 4 can be installed on both sides of the wall-attached frame 1 and connected to the building 6 through the locking pins 3. When in special environments, such as environments with large wind loads, or when the load of the tower crane body 5 is too high, the stability of the tower crane body 5 can be further increased by installing a connection between the reinforcement rods 4 and the building 6.

[0048] Working principle of the present invention:

[0049] Step 1, by opening a mounting hole 62 on the wall 61 and pre-installing the mother pin 31, when the wall-mounted structure is installed, the position of the sub-pin 32 is adjusted through the connecting seat 2, and when the sub-pin 32 corresponds to the mother pin 31 one by one, the sub-pin 32 is docked with the mother pin 31, and the locking rod 321 is driven to rotate by controlling the rotation of the sub-pin 32. Since the outer side of the locking rod 321 is provided with a spiral pattern, and the inner cavity of the mother pin 31 is provided with a spiral groove adapted thereto, the locking rod 321 gradually enters the inner cavity of the mother pin 31, and the anti-falling bead 322 enters the inner cavity of the mother pin 31. Since a plurality of anti-falling blocks 311 are provided in the inner wall of the mother pin 31, and since the side of the anti-falling block 311 close to the sub-pin 32 is provided with an inclined surface, when the sub-pin 32 enters the mother pin When the locking nut 322 is in the locked state, the locking nut 323 is in the locked state, and the locking nut 323 is in the locked state.

[0050] Step 2: By controlling the rotation of the worm 211, since the outer side of the worm 211 is meshed with the worm wheel 212, when the worm 211 rotates, the worm wheel 212 can be driven to rotate, and the worm wheel 212 drives the connecting rod 213 to rotate, and the connecting rod 213 drives the driving sprockets 214 at both ends to rotate. Since the outer side of the driving sprocket 214 is meshed with a chain 215, and the meshing relationship between the two chains 215 and the two driving sprockets 214 is different, the two chains 215 are driven to rotate in different directions through the two driving sprockets 214. Since the inner walls of the two chains 215 are respectively meshed with driven sprockets 216, so that the rotation directions of the two driven sprockets 216 are different, so that the first docking plate 22 and the second docking plate 23 can be rotated in different directions, and by controlling the rotation direction of the worm 211, the distance between the first docking plate 22 and the second docking plate 23 can be made close to each other, or the distance between the first docking plate 22 and the second docking plate 23 can be gradually increased, and the position of the sub-pin 32 can be adjusted by adjusting the distance between the first docking plate 22 and the second docking plate 23, so that the connection position of the sub-pin 32 and the mother pin 31 can be flexibly adjusted according to factors such as the area of ​​the building wall and the environment;

[0051] Step 3, when the wall-attached structure is installed, the tower crane body 5 and the building 6 are connected together. When the wall-attached structure is affected by external loads and wind, vibration or tension will be generated on the wall-attached structure. At this time, under the influence of the tension, the female pin 31 moves toward the entrance direction of the mounting hole 62. Since a pressure plate 317 is provided on the outer side of the fixing cap 315 and one side of the pressure plate 317 is set at an angle, when the female pin 31 moves toward the entrance direction of the mounting hole 62, the pressure plate 317 moves backward along the second movable groove 316. Since a gear 318 is provided on one side of the pressure plate 317, and the gear 318 is meshed with the rack 314, the female pin 31 moves backward along the second movable groove 316. The rack 314 moves outward, and the movable plate 313 moves outward under the drive of the rack 314. When the movable plate 313 moves outward, it goes deeper into the inner cavity of the pressure-resistant groove 622, thereby making the connection between the female pin 31 and the mounting hole 62 more stable. In addition, a fixing cap 315 is provided, and a reinforcement ring 621 is provided at the entrance of the mounting hole 62. The diameter of the fixing cap 315 is larger than the aperture of the reinforcement ring 621. The fixing cap 315 can be blocked by the reinforcement ring 621, thereby further preventing the female pin 31 from detaching from the inner cavity of the mounting hole 62, so that the wall-attached structure is more stably connected to the wall under the influence of external force, thereby preventing it from falling off.

[0052] The above shows and describes the basic principles, main features and advantages of the present invention. The present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention.
