Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a lifting device for cylindrical structures. Background Technique

[0002] Construction is a production activity in which people use various building materials and mechanical equipment to build various building products according to specific design blueprints within a certain space and time. It includes the entire production process from construction preparation, ground-breaking to project completion acceptance. In this process, construction preparation, construction organization design and management, earthwork, blasting, foundation, steel bar, formwork, scaffolding, concrete, prestressed concrete, masonry, steel structure, wood structure, structural installation and other works will be carried out. Construction is a technically complex production process that requires construction workers to use their wisdom and creatively apply theories such as materials, mechanics, structures, and processes to solve the technical problems constantly emerging during construction, ensuring project quality and construction safety. This construction process is carried out by multiple types of workers operating within a limited time and a certain space. The supply of hundreds of materials and the operation of various mechanical equipment require scientific and advanced organizational management measures and the adoption of advanced construction techniques to successfully complete this production process. This process is also a process with relatively high economic efficiency. A large amount of manpower, material resources, and financial resources will be consumed during construction. Therefore, it is required to consider its economic benefits everywhere during construction and take measures to reduce costs. The focus of attention during the construction process has always been project quality, safety (including environmental protection), progress, and cost.

[0003] The application number is CN201621004146.4, which discloses a lifting device for cylindrical structures, used for lifting cylindrical structures in buildings, including an upper clamp, a lower clamp, and a surrounding plate. Wedge blocks that can slide up and down are assembled on the inner sides of the upper clamp and the lower clamp. Screws are provided on the wedge blocks. One end of the screw is connected to the wedge block, and the other end is connected to a motor. The output end of the motor is connected to a worm, and a turbine with a matching size is provided on the worm. A screw is fixed at the center of the turbine. The utility model uses the self-locking function of the turbine, worm, and worm gear to prevent the wedge block from disengaging from the slideway, with a simple structure and being suitable for industrial production.

[0004] Although the above-mentioned utility model uses the self-locking function of the turbine, worm, and worm gear to prevent the wedge block from disengaging from the slideway, with a simple structure and being suitable for industrial production, its drawback is that when the device is in use, the lifting transmission efficiency is relatively low, and the space that can carry the load is relatively small.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0025] Please refer to Figure 1 -Figure 4 As shown in the figure, the utility model is a lifting device for cylindrical structures, including a support assembly 1. A load-carrying lifting platform assembly 2 is installed on the front side of the support assembly 1, and a second lifting assembly 4 is installed on the top of the rear side thereof. A lifting transmission assembly 3 is installed on the rear side of the load-carrying lifting platform assembly 2.

[0026] By installing the second lifting assembly 4 on the device, when using this device, through its components, when lifting personnel and materials needed on the front side, other additional devices can be installed on the rear side to perform the lifting work together, thus maximizing the practicability of this device.

[0027] The support assembly 1 includes support rods 101. A number of reinforcing crossbars 102 are installed in the middle of the support rods 101, and a fixed bottom frame 104 is installed at the bottom thereof. Reinforcing diagonal rods 103 are installed around the top of the reinforcing crossbars 102. By installing the fixed bottom frame 104 in the support assembly 1 on the ground, the dangerous situation of displacement can be avoided. Then, the other reinforcing crossbars 102 and reinforcing diagonal rods 103 are tightly connected through connectors to complete the installation work.

[0028] The load-carrying lifting platform assembly 2 includes a platform surface 201. Guardrails 202 are installed around the platform surface 201, and an input notch 203 is opened on one side of the bottom thereof. A storage body 204 is installed at the corresponding bottom of the input notch 203.

[0029] The lifting transmission assembly 3 includes a rotating motor 301. A rotating gear 302 is installed on the rear side of the rotating motor 301. A fixed rack 303 is installed on one side of the rotating gear 302 and is installed on the clamping side plate 305. Lifting wheels 306 are installed on both sides of the clamping side plate 305. A clamping roller 304 is installed on the other side of the fixed rack 303. Under the action of the rotating motor 301, the rotating wheel 302 installed on the outside will be driven to rotate. The rotating gear 302 is installed on one side of the fixed rack 303 and has a mutual limiting relationship. After different rotation directions, it will perform ascending or descending work. During ascending or descending, the lifting wheels 306 arranged on both sides are used for sliding lifting, and through this, a centered and stable effect can be maintained.

[0030] The second lifting assembly 4 includes a mounting seat 401. A rotating clamping wheel 402 is installed inside the mounting seat 401. A traction steel cable 403 is installed in the middle of the rotating clamping wheel 402. One side of the traction steel cable 403 is installed on the top of the clamping side plate 305, and the other end is installed with an auxiliary mounting frame 404. The second lifting assembly 4 connected by the traction steel cable 403 will be driven to lift together. Different containers that need to be installed and are adapted to the auxiliary mounting frame 404 can be installed on the auxiliary mounting frame 404 to complete the second lifting space.

[0031] The fixed rack 303 includes a fixing bolt 3031, and the fixing bolt 3031 mounts the fixed rack 303 at the middle position of the reinforcing cross bar 102.

[0032] When using this device, first install the fixed chassis 104 in the bracket assembly 1 on the ground to avoid the dangerous situation of displacement. Then, fasten and connect the other reinforcing cross bars 102 and reinforcing diagonal bars 103 through connectors to complete the installation work. When it is necessary to rise for construction, the materials to be used can be placed inside the storage body 204 through the input notch 203 at this time. Then, the personnel can stand on the platform surface 201 to carry out the rising work. When carrying out the rising work, first, under the action of the rotating motor 301, the rotating wheel 302 installed on the outside will be driven to rotate. The rotating gear 302 is installed on one side of the fixed rack 303 and has a mutual limiting relationship. After different rotation directions, it will rise or fall. When rising or falling, it slides up and down through the lifting rotating wheels 306 arranged on both sides, which can maintain the effect of being centered and stable. At the same time, when the load-carrying lifting platform assembly 2 is lifting, the second lifting assembly 4 connected to it through the traction steel rope 403 will be driven to lift together. Different containers that meet the adaptation of the auxiliary installation frame 404 for installation can be installed on the auxiliary installation frame 404 to complete the second lifting space.
