Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a lifting device for elevator installation. Background Technology

[0002] With the rapid development of urban construction, externally attached elevators, such as capsule-type sightseeing elevators and other special elevators, are commonly installed in high-rise buildings. These elevators require dedicated tracks for installation. Currently, the installation of externally attached elevators in China mainly employs two methods: tower crane hoisting and winch-assisted hoisting. Using tower cranes for elevator installation requires prolonged crane usage, severely impacting the normal construction progress of other sub-projects and preventing orderly cross-operations on the construction site, thus reducing overall construction efficiency. Conversely, when using winches for hoisting, their structural limitations restrict movement to vertical lifting only, preventing horizontal position adjustments. This makes it difficult to guarantee the installation accuracy of the elevator tracks and also prolongs the construction period.

[0003] Furthermore, existing installation methods generally suffer from problems such as complex operation, low equipment turnover rate, and high construction costs. In particular, during the precise positioning and installation of elevator tracks and equipment, the lack of a reliable leveling mechanism often requires repeated adjustments to complete the installation, which not only reduces construction efficiency but also increases construction safety hazards. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a lifting device for elevator installation that has high installation accuracy, simple operation, low cost and higher construction efficiency.

The hoisting section can be vertically raised and lowered along the elevator shaft, and the first pulley is disposed on the translation section.

[0009] Furthermore, the first driving component includes a hoisting winch and a first traction rope. The hoisting winch is connected to the hoisting unit via the first traction rope, so that the hoisting unit can be vertically raised and lowered along the elevator shaft.

[0010] Furthermore, the translation part is provided with a second pulley arranged opposite to it, and the hoisting part is provided with at least one third pulley. One end of the first traction rope is fixedly connected to the support assembly, and passes through the second pulley and the third pulley in sequence before being connected to the hoisting winch for transmission.

[0011] Furthermore, the second driving component includes a luffing winch and a second traction rope. The two ends of the second traction rope are respectively connected to the two sides of the translation part. The luffing winch is used to drive the traction rope to drive the translation part to reciprocate along the support arm.

[0012] Furthermore, the second driving component also includes a plurality of fourth pulleys, which are disposed on the transmission path of the second traction rope. The luffing winch is disposed between the plurality of fourth pulleys, and the fourth pulleys are used to support and guide the second traction rope.

[0029] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0030] During the elevator shaft installation process, refer to Figure 1-3First, fixing components 10 are installed at the side beams on both sides of the elevator shaft. These fixing components 10 can be embedded parts, providing a stable foundation support for the entire device. Then, a support component 20 is fixedly connected to the fixing components 10. The support component 20 can be in the form of a support frame to ensure the stability of the entire structure. A transport component 30 is installed on the support component 20. The transport component 30 can be a crossbeam structure, providing a motion track for the material conveying mechanism 40. The material conveying mechanism 40 is installed on the transport component 30, enabling horizontal and vertical material transport. For example, during elevator track installation, the material conveying mechanism 40 can accurately transport components such as the elevator guide rail 32 and counterweight guide rail 32 to the installation position.

[0031] Reference Figure 1 , 3 The first drive unit 50 is installed on one side of the elevator shaft and, through a transmission connection with the material conveying mechanism 40, drives the material conveying mechanism 40 to move vertically. For example, when installing elevator components on different floors, the lifting height of the materials can be precisely controlled. The second drive unit 60 is installed on the other side of the elevator shaft and, through a transmission connection, controls the horizontal movement of the material conveying mechanism 40. This allows for accurate positioning of the elevator guide rails 32 at different horizontal installation positions, thereby achieving efficient installation of the elevator equipment. This structural design makes the entire elevator installation process more flexible and efficient, ensuring both construction safety and improved construction efficiency.

[0032] Among them, the transport component 30 is the boom of the crane, which is assembled using existing tower crane accessories and winches, requiring no on-site processing and facilitating installation and disassembly. Furthermore, the boom of the crane is strong and resistant to deformation, and the materials can be reused multiple times, ensuring construction safety while saving costs and improving construction efficiency.

[0033] The support component 20 is a stirrup support structure, made by welding 20mm thick steel plates together. Multiple steel plates are welded together at specific intervals to form a 700*300*300 structure. This structure ensures both the strength of the support component 20 and provides stable support for the entire lifting device. The stirrup support can withstand loads from all directions from the material conveying mechanism 40. The multiple welded steel plates form an integral support structure, ensuring stability and safety during elevator installation.

[0034] The embedded parts are made of 16mm thick steel plates and φ16 bent anchor bars, which are processed and welded together.

[0035] In some embodiments, refer to Figure 1The structure of the transport component 30 includes a support arm 31 and a guide rail 32. The guide rail 32 provides a motion trajectory for the material conveying mechanism 40. The first pulley 411 on the material conveying mechanism 40 cooperates with the guide rail 32 to achieve stable movement of the material conveying mechanism 40 along the guide rail 32. For example, when installing the elevator guide rail 32, the first pulley 411 on the material conveying mechanism 40 closely cooperates with the guide rail 32 of the transport component 30. Through rolling contact, it ensures that the material conveying mechanism 40 can move smoothly along the guide rail 32. This not only ensures the stability of material conveying but also reduces frictional resistance during movement, making the transportation and installation of elevator components smoother and safer.

[0036] In some embodiments, refer to Figure 2 The material conveying mechanism 40 includes a translation section 41 that can move horizontally along the support arm 31 and a hoisting section 42 mounted on the translation section 41. The translation section 41 moves horizontally by cooperating with the guide rail 32 via a first pulley 411 mounted thereon, while the hoisting section 42 can move vertically up and down within the elevator shaft. For example, when installing the elevator guide rail 32, the translation section 41 can move horizontally along the support arm 31 to the desired position via the first pulley 411, while the hoisting section 42 can stably lift heavy components such as the elevator guide rail 32 and move them vertically up and down within the elevator shaft. Through the coordinated horizontal movement of the translation section 41 and the vertical movement of the hoisting section 42, elevator components can be accurately delivered to any installation position within the elevator shaft, greatly improving the efficiency and accuracy of elevator installation.

[0037] Furthermore, anti-collision blocks 413 are provided at both ends of the translation part 41. These anti-collision blocks 413 can effectively prevent excessive displacement of the translation part 41 during horizontal movement. When the translation part 41 moves to the limit position, the anti-collision blocks 413 can play a buffering and limiting role, avoiding collision between the translation part 41 and other components, thereby protecting the safety of the equipment and installation components.

[0038] Specifically, the first driving component 50 consists of a hoisting winch 51 and a first traction rope 52. The hoisting winch 51 is connected to the hoisting part 42 through the first traction rope 52, thereby realizing the vertical lifting and lowering movement of the hoisting part 42 in the elevator shaft.

[0039] In some embodiments, refer to Figure 2The translation section 41 is equipped with a second pulley 412 arranged opposite to it, and the hoisting section 42 is equipped with at least one third pulley 421. The second pulley 412, the third pulley 421, and the first traction rope 52 form a complete transmission system. One end of the first traction rope 52 is first fixedly connected to the support assembly 20, and then passes sequentially through the second pulley 412 on the translation section 41 and the third pulley 421 on the hoisting section 42, finally forming a transmission connection with the hoisting winch 51, thus constituting a complete lifting transmission path. For example, when installing the elevator guide rail 32, the hoisting winch 51 controls the winding and unwinding of the first traction rope 52, driving the first traction rope 52 to move between the second pulley 412 and the third pulley 421, thereby achieving precise lifting and lowering of the hoisting section 42.

[0040] In some embodiments, refer to Figure 1 , 3 The second driving component 60 includes a luffing winch 61 and a second traction rope 62. The two ends of the second traction rope 62 are connected to the left and right sides of the translation unit 41, respectively. The luffing winch 61 controls the movement of the second traction rope 62 to achieve the reciprocating movement of the translation unit 41 along the support arm 31. When it is necessary to adjust the horizontal distance of the installation position, the luffing winch 61 can drive the second traction rope 62 to move the translation unit 41 left and right on the support arm 31. By controlling the forward and reverse rotation of the luffing winch 61 to control the winding and unwinding of the second traction rope 62, the translation unit 41 can be precisely moved to the installation position of the elevator guide rail 32, ensuring the horizontal positioning accuracy of the elevator components.

[0041] Furthermore, the transmission system of the second drive unit 60 also includes multiple fourth pulleys 63, which are arranged on the transmission path of the second traction rope 62. The luffing winch 61 is positioned between these fourth pulleys 63. Through the supporting and guiding role of the fourth pulleys 63, the movement of the second traction rope 62 is ensured to be more stable and reliable. When the luffing winch 61 drives the second traction rope 62 to move the translation unit 41, the fourth pulleys 63 can provide the necessary supporting force for the second traction rope 62, while guiding the second traction rope 62 to move along the predetermined transmission path, preventing the second traction rope 62 from deviating or slack. This multi-pulley guiding and supporting design makes the horizontal movement of the translation unit 41 more stable and precise.

Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
