Description

Technical Field

[0001] This application relates to the field of hoisting mechanism technology, and in particular to a hoisting mechanism with protective functions. Background Technology

[0002] Lifting operations refer to the use of lifting equipment to lift prefabricated components or structures from a factory or construction site and move them to a designated location. In addition to prefabricated components, materials and tools used during construction also need to be vertically transported to a specified height. Commonly used lifting equipment includes tower cranes, mast cranes, crawler cranes, truck cranes, and floating cranes, etc., used for structural lifting in various types of civil engineering projects and construction site environments.

[0003] When hoisting large equipment to lower floors and there is limited working space, hoisting holes are usually reserved in the building floor slab. A hoisting mechanism is arranged above the hoisting hole to lift the equipment and lower it along the hoisting hole to the designated floor. Since the equipment and the hoisting mechanism are flexibly connected by slings and the working space is limited, the equipment is prone to swaying and colliding with the hoisting hole or other building structures during the lowering process, which can damage the equipment. At the same time, the limited working space makes it difficult for most hoisting equipment to work. Therefore, a hoisting mechanism with protective functions is proposed to address the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a lifting mechanism with protective function, which overcomes the shortcomings of the prior art and aims to solve the problems that the equipment is prone to collision with the lifting hole or other building structures due to shaking during the lifting and lowering process, and that most lifting equipment is difficult to operate in a limited space.

[0005] To achieve the above objectives, this application provides the following technical solution: A lifting mechanism with protective functions includes a lifting device and a guide cage. A lifting balance beam is connected to the lifting device. The lifting balance beam is slidably disposed in the guide cage. The lifting balance beam includes a cross-shaped beam body. A set of extended mounting arms is fixedly disposed at each of the four extended ends of the cross-shaped beam body. Rollers are rotatably disposed between the extended mounting arms. Several lifting hooks are fixedly disposed on the lower end face of the cross-shaped beam body.

[0006] By adopting the above technical solution, the connection between the hoisting equipment and the equipment to be hoisted can be realized by using the hoisting balance beam as an intermediate body. At the same time, the hoisting balance beam can optimize the stress situation of the equipment to be hoisted. In particular, the hoisting balance beam can slide up and down along the guide protective cage, so that the equipment hoisted under the hoisting balance beam can be lowered straight, avoiding the equipment from swaying and colliding with the external structure during the descent. Meanwhile, the guide protective cage can separate the hoisting space from the building space, improving the safety during the hoisting process.

[0007] As a preferred technical solution of this application, the guide cage includes an upper ring beam and a lower ring beam, and four sets of guide structures are fixedly arranged between the upper ring beam and the lower ring beam. Each set of guide structures consists of two symmetrically arranged guide plates.

[0008] By adopting the above technical solution, the rollers on the hoisting balance beam can be constrained to slide within the guide plate, thereby enabling the hoisting balance beam to slide up and down along the laying path of the guide plate.

[0009] As a preferred technical solution of this application, several sets of connecting folding rods are fixedly connected between the guide plates and arranged at equal intervals along the vertical direction. The connecting folding rods are right-angled bent rods and their two ends are respectively bolted to the outer end face of the corresponding guide plate.

[0010] By adopting the above technical solution, the guide plate can be connected in the horizontal direction by the connecting folding rod to form a whole, which can avoid the insufficient stability of the guide plate due to its excessive length-to-slenderness ratio.

[0011] As a preferred technical solution of this application, a through groove is provided in the middle of the inner side of the four sides of the upper ring beam, and a guide groove is provided in the inner side of the guide plate, and the through groove and the guide groove are connected.

[0012] By adopting the above technical solution, a constraint groove structure for the roller to roll can be formed, so that the roller can roll up and down along the groove.

[0013] As a preferred technical solution of this application, a fixing foot is fixedly provided at the middle of the outer side of each of the four sides of the upper ring beam, and a through mounting hole is provided on the fixing foot.

[0014] By adopting the above technical solution, the guide cage can be installed as a whole in the hoisting hole using fixed feet, providing the necessary conditions for the fixed installation of the guide cage.

[0015] As a preferred technical solution of this application, the hoisting equipment includes a hoisting gantry and a winch. The hoisting gantry includes two opposing side columns, a top beam is fixedly mounted on the side columns, a pulley assembly is fixedly mounted at the center of the lower end face of the top beam, and a sling is wound on the winch. The sling is laid around the upper part of the pulley assembly and a hoisting balance beam is fixedly connected to its end.

[0016] By adopting the above technical solution, the hoisting balance beam can be moved up and down by the working drive of the winch, thereby driving the equipment hoisted below the hoisting balance beam to move up and down. Moreover, the overall structure of the hoisting part is simple and easy to assemble, and it can be applied to the working environment of equipment hoisting in a limited space.

[0017] As a preferred technical solution of this application, the side columns are fixedly installed on the building walls on both sides by anchor rods.

[0018] By adopting the above technical solution, the side columns can be firmly fixed, providing the necessary conditions for subsequent hoisting work.

[0019] The beneficial effects of this application are: the hoisting balance beam can slide up and down along the guide cage, so that the equipment hoisted under the hoisting balance beam can be lowered straight, avoiding the equipment from swaying and colliding with the external structure during the lowering process. At the same time, the guide cage can separate the hoisting space from the building space, improving the safety during the hoisting process. Moreover, the overall structure of the hoisting part is simple and easy to assemble, and it can be applied to the working environment of equipment hoisting in a limited space.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Reference Figure 1-2A lifting mechanism with protective functions includes a lifting device 1 and a guide cage 3. A lifting balance beam 2 is connected to the lifting device 1 and slides within the guide cage 3. The lifting balance beam 2 includes a cross-shaped beam body 21. Each of the four extended ends of the cross-shaped beam body 21 is fixedly equipped with a set of extended mounting arms 22. Rollers 23 are rotatably arranged between the extended mounting arms 22. Several lifting hooks 24 are fixedly arranged on the lower end face of the cross-shaped beam body 21. The lifting balance beam 2 can be used as an intermediate body to connect the lifting device 1 and the equipment to be lifted. At the same time, the lifting balance beam 2 can optimize the stress situation of the equipment to be lifted. In particular, the lifting balance beam 2 can slide up and down along the guide cage 3, so that the equipment lifted below the lifting balance beam 2 can be lowered straight, avoiding the equipment from swaying and colliding with the external structure during the lowering process. Meanwhile, the guide cage 3 can separate the lifting space from the building space, improving the safety during the lifting process.

[0024] Reference Figure 3 The guide cage 3 includes an upper ring beam 31 and a lower ring beam 32. Four sets of guide structures are fixedly installed between the upper ring beam 31 and the lower ring beam 32. Each set of guide structures consists of two symmetrically arranged guide plates 33. The guide plates 33 can constrain the rollers 23 on the hoisting balance beam 2 to slide within them, thereby constraining the hoisting balance beam 2 to slide up and down along the laying path of the guide plates 33. In addition, several sets of connecting folding rods 34 are fixedly connected between the guide plates 33 and are arranged at equal intervals in the vertical direction. The connecting folding rods 34 are right-angle bent rod structures and their two ends are respectively bolted to the outer end face of the corresponding guide plate 33. This structure can connect the guide plates 33 in the horizontal direction with the connecting folding rods 34 to form a whole, which can avoid the insufficient stability of the guide plates 33 due to their own excessive slenderness ratio.

[0025] Reference Figure 4 The upper ring beam 31 has through grooves 311 in the middle of the inner side of each of its four sides, and the guide plate 33 has guide grooves 331 in the middle of its inner side. The through grooves 311 and guide grooves 331 are connected. The above structure can form a constraint groove structure for the roller 23 to roll, so that the roller 23 can roll up and down along the groove. In addition, the upper ring beam 31 has fixed feet 35 in the middle of the outer side of each of its four sides. The fixed feet 35 have through mounting holes 351, which can be used to install the guide cage 3 as a whole in the hoisting hole, providing the necessary conditions for the fixed installation of the guide cage 3.

[0026] Reference Figure 5The hoisting equipment 1 includes a hoisting gantry and a winch 14. The hoisting gantry includes two opposing side columns 11. A top beam 12 is fixedly mounted on the side columns 11. A pulley assembly 13 is fixedly mounted at the center of the lower end face of the top beam 12. A sling 15 is wound on the winch 14. The sling 15 is laid around the upper part of the pulley assembly 13 and is fixedly connected to a hoisting balance beam 2 at its end. By adopting the above technical solution, the hoisting balance beam 2 can be moved up and down by the operation of the winch 14, thereby driving the equipment hoisted below the hoisting balance beam 2 to move up and down. Moreover, the overall structure of the hoisting part is simple and easy to assemble, and it can be applied to the working environment of equipment hoisting in a limited space. At the same time, the side columns 11 are fixedly mounted on the building walls on both sides by anchor rods 16, which can achieve a firm fixation of the side columns 11 and provide the necessary conditions for the subsequent hoisting work.

[0027] Working principle: First, the overall construction work is carried out. The side columns 11 are fixed to the building walls on both sides using anchor rods 16. The top beam 12 is fixed on the side columns 11. The winch 14 is installed on the ground at the hoisting site and the slings 15 are laid. Then, the guide cage 3 is installed in the hoisting hole using the fixed feet 35. The construction work is thus completed.

[0028] At the start of the hoisting process, the hoisting balance beam 2 is used as an intermediate body to connect the hoisting equipment 1 with the equipment to be hoisted, optimizing the stress on the equipment. Then, the sling 15 is fixedly connected to the hoisting balance beam 2. At this time, the operation of the winch 14 can drive the hoisting balance beam 2 to move up and down, thereby driving the equipment hoisted below the hoisting balance beam 2 to move up and down, and carrying out the hoisting work. During this process, the rollers 23 on the hoisting balance beam 2 can slide up and down in the guide grooves 331 on the guide plate 33 that constitutes the guide protective cage 3, so that the hoisting balance beam 2 slides up and down along the laying path of the guide protective cage 3, ensuring that the equipment hoisted below the hoisting balance beam 2 can be lowered straight, avoiding the equipment from shaking and colliding with the external structure during the lowering process. At the same time, the guide protective cage 3 can separate the hoisting space from the building space, improving the safety during the hoisting process.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
