Description

Technical Field

[0001] The utility model relates to the technical field of construction tools such as bridges, wind power, power plants, etc., and particularly relates to a hoisting device for the installation and positioning of ultra-long components. Background Technique

[0002] In the construction fields such as bridges, wind power, power plants, etc., a large number of construction materials such as large-volume steel plates and profiles are used. The lengths of the above materials are generally ultra-long materials exceeding 15 meters, and their installation and positioning are difficult. Currently, one crane or two cranes are commonly used in cooperation for hoisting and positioning. When using one crane, the lifting points will be staggered, so that the lifting points are not on the same horizontal line, which is easy to cause deformation at the lifting points. If the steel plate is thin, the deformation phenomenon will be more serious, and even the strength of the steel plate at the lifting points will be reduced or even unable to be used normally, resulting in material waste. If two cranes are used for simultaneous lifting, it will cause additional investment in mechanical equipment and personnel, greatly increasing the construction cost. Based on this, an auxiliary tool specifically suitable for the installation and positioning of ultra-long components is needed. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a hoisting device for the installation and positioning of ultra-long components, which helps to maintain hoisting balance and has a large structural strength.

[0004] To solve the above technical problem, the technical solution of the utility model is: a hoisting device for the installation and positioning of ultra-long components, including a hoisting cross beam of H-shaped steel structure. At the top of the upper flange of the hoisting cross beam, two upper lifting lugs for connecting with a crane are symmetrically installed. At both ends of the bottom of the lower flange of the hoisting cross beam, two symmetrically arranged outer lifting lugs are fixedly installed. At least one pair of cooperating inner lifting lugs is arranged between the two outer lifting lugs, and the two inner lifting lugs of the same pair are symmetrically welded to the lower flange of the hoisting cross beam. Between the two sides of the upper lifting lug and the upper flange of the hoisting cross beam, between the two sides of the outer lifting lug and the lower flange of the hoisting cross beam, and between the two sides of the inner lifting lug and the lower flange of the hoisting cross beam, lifting lug reinforcing plates are respectively fixedly welded. At least two downward-extending cross beam anti-tilting support devices are also fixedly installed on the lower flange of the hoisting cross beam, and the bottom ends of the cross beam anti-tilting support devices are arranged lower than the bottom ends of the outer lifting lugs and the inner lifting lugs.

[0005] As a preferred technical solution, the cross beam anti-tilting support device includes two anti-tilting support plates that straddle the lower flange of the hoisting cross beam and are fixedly welded relatively. The width of the anti-tilting support plate is not less than the width of the lower flange of the hoisting cross beam. At least one reinforcing support cross plate parallel to the lower flange of the hoisting cross beam is fixedly welded between the two anti-tilting support plates.

[0006] As a preferred technical solution, reinforcing support inclined plates are also respectively fixedly welded between each anti-tilting support plate and the lower flange of the hoisting cross beam.

[0007] As a preferred technical solution, beam strengthening plates are fixedly welded to both sides of the web of the hoisting crossbeam, and the beam strengthening plates are arranged in one-to-one correspondence with the lug strengthening plates.

[0008] As a preferred technical solution, the inner ends of the beam strengthening plates are abutted and welded to the surface of the web of the hoisting crossbeam, the upper and lower ends of the beam strengthening plates are fixedly welded to the upper flange and the lower flange of the corresponding hoisting crossbeam, and the outer ends of the beam strengthening plates are flush with the edges of the upper flange and the lower flange of the hoisting crossbeam.

[0009] As a preferred technical solution, the length of the hoisting crossbeam is not less than 10 m, and the thicknesses of the outer lug, the inner lug, and the outer lug are all not less than 30 mm.

[0010] As an improvement to the above technical solution, a lifting rope is detachably provided on the outer lug and / or the inner lug, both ends of the lifting rope are respectively connected with a hook, and a rectangular hoisting clamping groove is formed inside the hook.

[0011] Due to the adoption of the above technical solution, the present utility model has the following beneficial effects: During use, the entire hoisting device is supported on the surface of a super-long piece to be hoisted, such as a large-volume steel plate, by using the crossbeam anti-tilting support device. The lifting rope is assembled with the outer lug or / and the inner lug, and the hook is assembled with the steel plate. Then, the hoisting can be carried out by using the hoisting locking device on the crane in cooperation with the upper lug. The cooperation between the outer lug and the inner lug helps to maintain the balance of hoisting. The arrangement of multiple lug strengthening plates and beam strengthening plates greatly improves the overall strength of the hoisting device, making it have strong load-bearing capacity and long service life. Two or more hoisting devices can be set up to be used alternately to improve the hoisting and positioning efficiency of super-long pieces, thereby improving the project construction efficiency.

Detailed implementation mode

[0017] The present utility model will be further elaborated below in conjunction with the accompanying drawings and embodiments. In the following detailed description, only some exemplary embodiments of the present utility model are described by way of illustration. Undoubtedly, those of ordinary skill in the art can recognize that the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the drawings and description are illustrative in nature and are not used to limit the protection scope of the claims.

[0018] As Figure 1 、 Figure 2 and Figure 3 shown, the hoisting device for installing and positioning over-length parts is used for hoisting over-length parts such as large-volume steel plates, profiles, etc. for installation and positioning, and includes a hoisting cross beam 1 made of H-shaped steel structure. The length of the hoisting cross beam 1 is not less than 10 m, and H350×350 steel can be selected. Therefore, the hoisting cross beam 1 is formed with an upper wing plate, a lower wing plate and a web, and preferably an integral non-spliced steel section. If it is really necessary to splice and form due to conditions not allowing, full penetration welding shall be adopted and at least a reinforcing plate shall be welded on one side of the weld to ensure the load-bearing strength of the hoisting cross beam 1.

[0019] In this embodiment, two upper lifting lugs 2 for connecting with a crane are symmetrically installed at the top of the upper wing plate of the hoisting cross beam 1. The upper lifting lugs 2 are used to cooperate with a crane such as a hoist, a traveling crane, etc. through a lifting locking device to realize the lifting, transfer and positioning of the whole hoisting device and the over-length part. Two symmetrically arranged outer lifting lugs 3 are fixedly installed at both ends of the bottom of the lower wing plate of the hoisting cross beam 1, and at least a pair of inner lifting lugs 4 for cooperating with each other are arranged between the two outer lifting lugs 3. The two inner lifting lugs 4 of the same pair are symmetrically welded to the lower wing plate of the hoisting cross beam 1. The outer lifting lugs 3 or / and the inner lifting lugs 4 are used for assembling with the over-length part. The thicknesses of the outer lifting lugs 3, the inner lifting lugs 4 and the outer lifting lugs 3 are not less than 30 mm to ensure sufficient load-bearing capacity.

[0020] Specifically, a lifting rope 5 is detachably provided on the outer lifting lug 3 and / or the inner lifting lug 4. The lifting rope 5 is made of a steel wire rope with relatively high strength. Hooks 6 are respectively connected to both ends of the lifting rope 5. A rectangular lifting clamping groove is formed inside the hook 6. The lifting rope 5 and the hook 6 are used to bind the extra-long piece during hoisting and positioning in this embodiment. The two outer lifting lugs 3 are fixedly installed at both ends of the lifting crossbeam 1. Since the lifting crossbeam 1 can be up to 10 m long, the distance between the two is relatively large. Coupled with the large length and weight of the extra-long piece, affected by the lifting points and its own gravity, the part of the extra-long piece between the two outer lifting lugs 3 is prone to sagging after hoisting. At this time, the cooperation of the lifting rope 5, the hook 6 and the inner lifting lug 4 can be used to support and limit the sagging part, so as to prevent the extra-long piece from detaching from the hoisting device during the hoisting and positioning process due to severe sagging, thereby improving the safety and stability of hoisting. The lifting clamping groove can also play a certain limiting role on the end of the extra-long piece, so that even if there is a sagging phenomenon, it is difficult to detach from the hook 6 due to the limiting effect of the upper inner wall of the lifting clamping groove on its end, thereby further improving the safety of hoisting.

[0021] Lifting lug reinforcing plates 7 are respectively fixedly welded between the two sides of the upper lifting lug 2 and the upper wing plate of the lifting crossbeam 1, between the two sides of the outer lifting lug 3 and the lower wing plate of the lifting crossbeam 1, and between the two sides of the inner lifting lug 4 and the lower wing plate of the lifting crossbeam 1. The fixing effect and load-bearing strength of the corresponding upper lifting lug 2, outer lifting lug 3 and inner lifting lug 4 can be enhanced through the lifting lug reinforcing plates 7.

[0022] To further improve the load-bearing capacity of the lifting crossbeam 1, in this embodiment, beam reinforcing plates 8 are respectively fixedly welded on both sides of the web of the lifting crossbeam 1, and the beam reinforcing plates 8 are arranged in one-to-one correspondence with the lifting lug reinforcing plates 7. Specifically, the inner end of the beam reinforcing plate 8 abuts and is welded to the surface of the web of the lifting crossbeam 1. The upper and lower ends of the beam reinforcing plate 8 are fixedly welded to the upper wing plate and the lower wing plate of the corresponding lifting crossbeam 1 respectively. The outer end of the beam reinforcing plate 8 is flush with the edges of the upper wing plate and the lower wing plate of the lifting crossbeam 1. This can not only ensure that the beam reinforcing plate 8 provides the strongest possible strengthening and supporting effect on the lifting crossbeam 1, but also ensure that the external structure of the lifting crossbeam 1 is relatively regular for convenient hoisting use.

[0023] At least two downward-extending anti-tilting support devices of the lifting beam are fixedly installed on the lower wing plate of the lifting beam 1, and the bottom ends of the anti-tilting support devices of the beam are arranged lower than the bottom ends of the outer lifting lugs 3 and the inner lifting lugs 4, so as to play a supporting role when the device is assembled with the ultra-long piece. When the ultra-long piece is a large-volume steel plate, the lifting beam 1 can be supported at the middle of the surface of the steel plate to facilitate the clamping fit between the lifting hook 6 and the two edges of the steel plate; when the ultra-long piece is a profile, the lifting beam 1 can be supported on the ground at the side of the profile by using the anti-tilting support device of the beam. It is convenient to use multiple lifting devices in cooperation, so that one is in the process of lifting, and the others can be pre-assembled with the ultra-long piece and wait for lifting, thereby improving the lifting and positioning efficiency of the ultra-long piece and helping to accelerate the project progress.

[0024] Specifically, the anti-tilting support device of the beam includes two anti-tilting support plates 9 that straddle the lower wing plate of the lifting beam 1 and are fixedly welded relatively. The width of the anti-tilting support plate 9 is not less than the width of the lower wing plate of the lifting beam 1. At least one reinforcing support cross plate 10 parallel to the lower wing plate of the lifting beam 1 is fixedly welded between the two anti-tilting support plates 9. Reinforcing support inclined plates 11 are respectively and fixedly welded between each anti-tilting support plate 9 and the lower wing plate of the lifting beam 1.

[0025] In this embodiment, multiple sets can be provided and cooperate with a crane. According to the specific length of the ultra-long piece, the outer lifting lug 3 or the inner lifting lug 4 can be flexibly selected, or the safe and stable lifting and positioning of the ultra-long piece can be achieved through the cooperation of the two.

[0026] The description of the present invention is given for purposes of illustration and description, and is not intended to be exhaustive or to limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better explain the principles of the present invention and its practical application, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.
