Description

Technical Field

[0001] The utility model belongs to the technical field of building construction work platforms, in particular to a work platform used for lifting and installing masonry materials. Background Art

[0002] With the development of the construction industry and the needs of the actual use of buildings, masonry walls have become the main component of building structures. Masonry walls provide necessary support for buildings, ensuring the overall stability and wind and earthquake resistance of buildings; masonry walls are often used to separate building spaces, forming different functional areas to meet the needs of people for various activities.

[0003] During the construction of masonry walls at the construction site, the installation of masonry materials is inconvenient due to the generally high overall height and long span of the wall. The more popular practice in the industry is to use wooden benches or gantry scaffolding to assist workers in lifting and installing masonry materials. For higher masonry walls, it is also necessary to rent a lifting vehicle for cooperation. This practice is not safe enough, has high costs, and is inefficient during construction. The device used is large and inconvenient to move.

[0004] For example, a folding hoist for construction operations disclosed in a Chinese invention patent with an application publication date of 2021.02.02 and application publication number CN112299241A comprises an operating folding platform placed on two sets of lifting support leg assemblies, and the height of the operating folding platform is adjusted by lifting support leg assemblies; a pulley assembly is connected to the operating folding platform, a deceleration and check assembly is connected to the lifting support leg assembly, a rope is wound between the pulley assemblies, and the other end of the rope is connected to the deceleration and check assembly.

[0005] The above-mentioned prior art solves the problem that heavy objects are easy to fall back when lifted during maintenance, the platform is not easy to transport, and the space is occupied and inconvenient to fold and disassemble. However, it has the following disadvantages:

[0006] 1. When the working platform of the folding hoist is separated from the outriggers, the working platform can be folded and stored, but there are many components, and one worker cannot complete the transfer, so it can only be moved with the help of transportation tools;

[0007] 2. The working platform is only used to install the hoist and cannot be used by installation workers to climb onto the working platform to perform work.

[0008] Therefore, how to effectively solve the problem that the working platform can only be moved with the help of transportation tools after being folded and cannot be used by installation workers to climb onto the working platform to perform operations is a technical problem that needs to be solved urgently. Utility Model Content

[0009] In view of the deficiencies in the above-mentioned background technology, the utility model proposes a work platform for lifting and installing masonry materials, which solves the problem that the work platform can be easily moved at any time without the aid of transportation tools and the installation workers cannot climb onto the work platform to perform operations.

[0010] The technical solution of this application is:

[0011] A work platform for lifting and installing masonry materials comprises a hinged mobile base unit and a folding frame unit. The sides of the mobile base unit and the folding frame unit are both provided with ladders. When the folding frame unit is unfolded, the ladder is connected from the ground to the top of the work platform. The lifting structure in the folding frame unit is connected to the engine in the mobile base unit. When idle or moving, the work platform can be folded to reduce the overall size. After folding, the sliding of the universal wheels is not affected. Only one worker is required to push the work platform for transfer, which is convenient for entering the construction elevator, passing through a smaller door opening, and entering a smaller construction site. Workers can use the ladder to operate from the ground to the work platform, which is convenient for lifting and installing auxiliary masonry materials. The work platform and the ladder are both made of steel structure, which can bear heavy objects and have a high safety factor.

[0012] Furthermore, the shape of the mobile base unit is combined with the shape of the folding frame unit to form a quadrilateral. After forming the quadrilateral, the volume of the working platform is reduced and the shape is regular, which is convenient for entering a construction elevator, passing through a smaller door opening, and entering a smaller construction site.

[0013] Furthermore, the mobile base unit includes a frame 1 arranged on the base, a ring 1 is arranged at the hinged end of the frame 1, and the folding roller passes through the ring 1 and is hinged to the folding frame unit.

[0014] Furthermore, the folding frame unit includes a frame 2 provided with a circular ring, the folding roller passes through the circular ring 1 and the circular ring 2 is hinged, and when the folding frame unit is unfolded, the frame 2 is overlapped on the frame 1.

[0015] Furthermore, the lifting structure includes a fixed pulley arranged at the second rotating end of the frame, and one end of the rope is wound around the fixed pulley and connected to the engine.

[0016] Furthermore, at least two fixed pulleys are coaxially arranged, one fixed pulley is arranged on the top of the second frame, and the remaining fixed pulleys are arranged along the lifting direction of the masonry material.

[0017] Furthermore, a fixed pulley arranged along the lifting direction of the masonry material is connected to the second frame through an extension rod.

[0018] Furthermore, a hook is provided at the other end of the rope.

[0019] Furthermore, the ladder is provided on the side surface of the frame 1 and the overlapping surface of the frame 1 and the frame 2, and the side surface and the overlapping surface are broken line segments connected end to end.

[0020] Furthermore, a universal wheel is provided on the lower surface of the base, and a brake is provided on the universal wheel. When the working platform needs to be moved, it is convenient for the staff to push and move it, which is convenient and labor-saving and can be operated by one person. When the working platform is positioned, the brake is pressed to fix the position.

[0021] The specific beneficial effects of the utility model include:

[0022] 1. When idle or moving, the work platform can be folded to reduce its overall size. Folding does not affect the sliding of the universal wheels. Only one worker is needed to push the work platform for transfer, making it easier to enter the construction elevator, pass through smaller door openings, and enter smaller construction sites.

[0023] 2. Workers can climb from the ground to the top of the working platform through ladders, which is convenient for lifting and installing auxiliary masonry materials. The working platform and ladders are made of steel, can carry heavy objects, and have a high safety factor;

[0024] 3. During construction, the engine can be used to control the hook to hoist the masonry materials, thereby improving the efficiency of masonry wall construction. BRIEF DESCRIPTION OF THE DRAWINGS
