Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a small air conditioner outdoor unit hoisting device. Background Technology

[0002] Currently, the proportion of fully furnished projects in real estate development has increased significantly, and the standards for fully furnished delivery mostly involve the installation of outdoor air conditioning units. In conventional buildings, air conditioning units are typically installed on outdoor equipment platforms. Since air conditioning installation occurs in the later stages of project construction, outdoor tower cranes, construction elevators, and other vertical transportation machinery have already been dismantled. Furthermore, air conditioning units generally weigh over 100 kilograms. Even if an indoor elevator is available, manually moving and installing the air conditioning unit onto the outdoor equipment platform remains very difficult.

[0003] Currently, there is no equipment on the market specifically designed to solve this problem. The purpose of this invention is to provide a small hoisting device that is simple in structure and flexible in installation, in order to solve the various difficulties encountered in the installation of air conditioning outdoor units in building projects, thereby reducing the difficulty of installing air conditioning outdoor units. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this utility model proposes a small air conditioner outdoor unit hoisting device, which has a simple structure and flexible installation, and is conducive to solving the problem of difficult installation of air conditioner outdoor units in residential projects.

[0005] To achieve the above objectives, the present invention provides a small air conditioner outdoor unit hoisting device, which includes a base installed on the roof, a winch on the base, a boom at one end of the base facing the outer side of the building, a pulley at the end of the boom away from the winch, a wire rope connected to the winch, the wire rope extending downwards around the pulley, and a hook at the end of the wire rope away from the winch.

[0006] Furthermore, a counterweight is also provided on the base, which is located on the side of the winch away from the boom.

[0007] Furthermore, the height of the end of the boom furthest from the base is above the height of the end of the boom connected to the base, and the boom is set obliquely upward in the direction of outward extension.

[0008] Furthermore, a first constraint ring is provided in the middle of the boom, and a second constraint ring is provided at the end of the boom away from the base, through which the wire rope passes.

[0009] Furthermore, the first constraint ring and the second constraint ring have the same structure, and the cross-section of the first constraint ring and the second constraint ring is a pentagon with a protruding top.

[0010] Furthermore, the base consists of four square tubes, which are arranged in pairs to form a rectangular base.

[0011] This utility model relates to a small air conditioner outdoor unit hoisting device, which has a simple structure and flexible installation, and helps to solve the problem of difficult installation of air conditioner outdoor units in residential projects. Attached Figure Description

[0017] The technical solution of this utility model will be more clearly and completely explained below with reference to the accompanying drawings and through the description of the preferred embodiments of this utility model.

[0018] like Figure 1 and Figure 2 As shown, the preferred embodiment of this utility model of a small air conditioner outdoor unit hoisting device includes a base 1 installed on the roof. The base 1 includes four square tubes, which are arranged in pairs to form a rectangular base 1. Specifically, it can be welded from galvanized square tubes of 80mm*80mm*4mm and angle steel of 50mm*50mm*5mm.

[0019] like Figure 1 and Figure 2 As shown, a winch 2 is mounted on the base 1. Angle steel is mechanically drilled at the connection point between the winch 2 and the base 1, and the winch 2 is fixedly connected to the base 1 via bolt assemblies. A control switch is connected to the winch 2.

[0020] like Figure 1 and Figure 2 As shown, a boom 3 is provided at one end of the base 1 facing the outer side of the building. The height of the end of the boom 3 away from the base 1 is above the height of the end of the boom 3 connected to the base 1. The boom 3 is obliquely upward in the outward extension direction. The boom 3 is made of a single 2.5m to 3m galvanized square tube (specifications 80mm*80mm*4mm). Holes are drilled on the side of the tail end of the boom 3. The boom 3 is fixedly connected to the base 1 by bolt assembly.

[0021] like Figure 1 and Figure 3As shown, a pulley 4 is provided at the end of the boom 3 away from the winch 2, a first constraint ring 7 is provided in the middle of the boom 3, and a second constraint ring 8 is provided at the end of the boom 3 away from the base 1. The first constraint ring 7 and the second constraint ring 8 have the same structure, and the cross-section of the first constraint ring 7 and the second constraint ring 8 is a pentagon with a protruding top.

[0022] like Figure 1 and Figure 2 As shown, a steel wire rope 5 with a diameter of 13mm is connected to the winch 2. The steel wire rope 5 passes through the first constraint ring 7 and the second constraint ring 8, and extends downward around the pulley 4. A hook 6 is provided at the end of the steel wire rope 5 away from the winch 2.

[0023] like Figure 1 and Figure 2 As shown, a counterweight 9 is also provided on the base 1, and the counterweight 9 is located on the side of the winch 2 away from the boom 3. The weight of the counterweight 9 is much greater than the weight of the outdoor unit of the air conditioner.

[0024] Specific implementation process: Based on the actual project conditions, select a suitable area to assemble the crane. After the crane is installed, a trial lift must be conducted for confirmation. The crane can be lifted 200-500mm off the ground at 1.2 times the rated load. During actual lifting, first start winch 2, slide hook 6 to the height of the outdoor unit, and after hook 6 hooks the outdoor unit, select the appropriate gear and slowly lift the outdoor unit. Once it reaches the installation position, stop winch 2, and manually unload the outdoor unit from hook 6. Repeat the above process for each subsequent outdoor unit installation.

[0025] This utility model relates to a small air conditioner outdoor unit hoisting device, which has a simple structure and flexible installation, and helps to solve the problem of difficult installation of air conditioner outdoor units in residential projects.

[0026] The above-described specific embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Various modifications, substitutions, and improvements made by those skilled in the art to the technical solutions of the present invention based on the provided description and drawings, without departing from the design concept and spirit of the present invention, should all fall within the scope of protection of the present invention. The scope of protection of the present invention is determined by the claims.
