Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a soft attachment structure for a tower crane. Background Technique

[0002] A tower crane is an industrial equipment commonly used for heavy material handling and installation, usually active in construction sites, ports, shipyards and many other places that require a large amount of hoisting operations. When the tower crane is attached to the building exterior wall, steel cables are often used for fixation. However, the length of the steel cable is not easy to adjust, which leads to low installation efficiency. Therefore, a soft attachment structure for a tower crane is proposed.

[0003] Chinese Utility Model Patent Publication No.: CN 204111216 U, discloses a tower crane attachment structure for construction. The attachment frame in this structure consists of upper and lower frames and is connected by columns, and the height of the formed attachment frame is greatly increased compared with the prior art, making the overall stability of the tower crane better, and the attachment structure itself is not easy to deform. Pull rings are provided at the four corners of the upper and lower frames, and the steel wire rope connects the pull rings and the fixing rings on the fixing columns, so as to fix the tower crane through the fixing columns. Moreover, the fixing rings surround the outer side of the fixing columns and are fixed on the fixing columns by a single connecting rod. When installing the tower crane attachment, the position selection of the fixing columns is more free and is not easily affected by the distance and angle of the surrounding existing structures. The steel wire rope can be connected at an angle of 0 to 360°, meeting various installation conditions, and it is expected to be well applied in the technical field of construction tools. However, this tower crane attachment structure for construction cannot be fixed when attaching the standard section to the exterior wall, and the length of the steel wire rope is not adjustable, making the installation difficult.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1: As Figures 1-6 shown, a soft attachment structure of a tower crane provided by the present invention includes a standard section 1, a fixed ear 2 is fixedly connected to the outside of the standard section 1, a first reinforcing beam 3 is fixedly connected to the upper end of the fixed ear 2, a telescopic rod 4 is fixedly connected to the front end of the first reinforcing beam 3, a spring 5 is arranged on the outside of the telescopic rod 4, a top block 6 is fixedly connected to the front end of the telescopic rod 4, a fixed seat 7 is arranged in front of the top block 6, a buffer seat 8 is fixedly connected to the rear end of the fixed seat 7, a second reinforcing beam 9 is fixedly connected to the upper end of the first reinforcing beam 3, a locking assembly 10 is fixedly connected to the outside of the second reinforcing beam 9, a steel cable 11 is fixedly connected to the front end of the locking assembly 10, a connecting plate 12 is arranged in front of the locking assembly 10, and a connecting seat 13 is fixedly connected to the rear end of the connecting plate 12.

[0030] Specifically, the locking assembly 10 includes a mounting seat 1001, a fixed plate 1002, a rotating shaft 1003, a worm gear 1004, a limiting disc 1005, a worm 1006 and a runner 1007. A fixed plate 1002 is fixedly connected to the outside of the mounting seat 1001, a rotating shaft 1003 is rotatably connected to the inside of the mounting seat 1001, a worm gear 1004 is fixedly connected to the outside of the rotating shaft 1003, a limiting disc 1005 is arranged below the worm gear 1004, a worm 1006 is rotatably connected to the inside of the fixed plate 1002, and a runner 1007 is fixedly connected to the outside of the worm 1006. The advantage is that the locking assembly 10 is provided to tighten the steel cable 11 and connect the standard section 1 to the outer wall in a soft attachment manner.

[0031] Specifically, there are two sets of symmetrically identical reinforcement beams II 9, locking assemblies 10, steel cables 11, connecting plates 12 and connecting seats 13. Each set includes one reinforcement beam II 9, two locking assemblies 10, two steel cables 11, one connecting plate 12 and two connecting seats 13. The advantage is that two locking assemblies 10 are provided, which are respectively arranged on both sides of the standard section 1. There are two steel cables 11 arranged on each side of the standard section 1, so the force is dispersed and the fixation is firm.

[0032] Specifically, one end of the steel cable 11 is fixedly connected to the rotating shaft 1003, the other end of the steel cable 11 is sleeved on the connecting seat 13, and the worm 1006 is meshed with the worm gear 1004. The advantage is that the worm gear 1004 and the worm 1006 are provided. When performing soft attachment fixation, the connecting plate 12 and the outer wall are locked and connected by anchor bolts. At this time, the steel cable 11 is in a relaxed state. Rotating the runner 1007 drives the worm 1006 to rotate. The rotation of the worm 1006 drives the meshed worm gear 1004 to rotate, thereby driving the rotating shaft 1003 to rotate, winding up the steel cable 11 until the steel cable 11 is tightened.

The driving mode of the worm 1006 and the worm gear 1004 has a self-locking characteristic, avoiding the relaxation of the steel cable 11.

[0033] Embodiment 2: As Figures 2-6 shown, as an improvement over the previous embodiment.

[0034] Specifically, both the connecting plate 12 and the fixed seat 7 are locked and connected to the outer wall by anchor bolts. The advantage is that two fixed seats 7 are provided, which are locked and connected to the outer wall by anchor bolts. The buffer seat 8 cooperates with the telescopic rod 4, the spring 5 and the top block 6 to provide buffering.

[0035] Specifically, the buffer seat 8 corresponds to the top block 6, and both ends of the spring 5 are fixedly connected to the top block 6 and the telescopic rod 4 respectively. The advantage is that during installation, the telescopic rod 4 is fixedly installed on the reinforcement beam I 3. During the tightening process of the steel cable 11, the top block 6 approaches the buffer seat 8 until the top block 6 touches the buffer seat 8, and the steel cable 11 is tightened. When the standard section 1 is affected by strong winds towards the outer wall, the spring 5 and the telescopic rod 4 cooperate to buffer and weaken the wind force, improving the stability of the tower crane.

[0036] Specifically, there are two reinforcement beams I 3, and the reinforcement beam II 9 is fixedly connected to the reinforcement beam I 3. The advantage is that the reinforcement beam I 3 and the reinforcement beam II 9 cooperate to enclose and fix the outside of the standard section 1, with uniform force.

[0037] Working principle: When in use, the connecting plate 12 is locked and connected to the outer wall through anchor bolts, and the fixing seat 7 is locked and connected to the outer wall through anchor bolts. At this time, the steel cable 11 is in a relaxed state. Rotate the runner 1007 to drive the worm 1006 to rotate. The rotation of the worm 1006 drives the meshing-connected worm wheel 1004 to rotate, thereby driving the rotating shaft 1003 to rotate and winding up the steel cable 11. During the winding process of the steel cable 11, the top block 6 approaches the buffer seat 8 until the top block 6 is in tight contact with the buffer seat 8, and the steel cable 11 is completely tightened. The tightening process is convenient for operation and has a good adjustable effect. The driving mode of the worm 1006 and the worm wheel 1004 has a self-locking characteristic to prevent the steel cable 11 from loosening. There are two steel cables 11 arranged on each side of the standard section 1 to disperse the force and ensure firm fixation. When the standard section 1 is affected by strong winds facing the outer wall, the spring 5 and the telescopic rod 4 cooperate to buffer and weaken the wind force, improving the stability of the tower crane.
