Description

Technical Field

[0001] This utility model relates to a lifting device, and more particularly to a lightweight mobile lifting frame. Background Technology

[0002] Lifting equipment is widely used in material handling and production operations in industrial workshops. Large cranes, such as bridge cranes, are used to lift heavy materials or equipment, but require specialized personnel to operate, resulting in high costs. When lifting materials of medium to small weight (tens to hundreds of kilograms), lighter lifting equipment, such as electric hoists, manual hoists, and pneumatic hoists, is generally used. These specialized devices also need to be purchased and installed. However, these lighter lifting devices cannot be moved freely after installation, and even if they can be moved, they are only within a certain range, and cannot achieve unrestricted free movement. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the existing technology by providing a lightweight mobile hanger that is inexpensive, easy to inspect and maintain, and can be moved freely in narrow spaces, making it convenient to use.

[0004] The technical solution adopted by this utility model to achieve the above-mentioned objectives is as follows: a lightweight mobile hoist includes a base, support arms, a worm gear reducer, a boom, and a wire rope. Two support arms are hinged to the rear side of the base near the bottom end. The two support arms extend backward respectively, and load-bearing wheels are installed on the bottom surface of the rear side of the two support arms. Universal wheels are installed at the bottom end of the base. The worm gear reducer is installed on the support platform at the front side of the base. The output shaft of the worm gear reducer is connected to a rope winch, and the input shaft of the worm gear reducer is connected to a rotating handle. The bottom end of the boom is connected to the base. The upper end of the boom first extends upward and then backward to the upper side of the two support arms. The bottom end of the wire rope is wound around the rope winch. The upper end of the wire rope first extends along the direction of the boom, and then the wire rope passes around the front end of the boom and extends downward to connect to the hook.

[0005] A further technical solution of this utility model is that the included angle between the two support arms can be adjusted.

[0006] A further technical solution of this utility model is: a push-pull handle is connected to one side of the vertical section of the boom to facilitate pushing and moving the hanger, and the push-pull handle is obliquely connected to one side surface of the vertical section of the boom near the middle position.

[0007] A further technical solution of this utility model is as follows: guide rope wheels are installed at the top of the vertical section of the boom and at the top of the rear end of the boom, and a wire rope fixing ring is connected to the lower side of the rear end of the boom. The hook is a pulley hook. When the wire rope extends along the boom, it passes around the guide rope wheel and then extends downwards to pass around the pulley hook. Then the wire rope extends upwards to connect with the wire rope fixing ring.

[0008] This utility model discloses a lightweight mobile lifting frame with the following advantages: The frame is constructed from scrap steel welded from recycled equipment, forming a base, support arms, and a boom. A discarded worm gear reducer is used, with a handle connected to the input shaft and a rope winch connected to the output shaft. Manually rotating the handle drives the winch to rotate forward and backward, allowing for the winding and unwinding of the wire rope, thus lifting objects from the hook at the end of the wire rope. The equipment used to manufacture the mobile lifting frame is inexpensive. The base has casters at the bottom, and load-bearing wheels are connected to the lower rear ends of the two support arms, enabling the mobile lifting frame to move freely within the production workshop to the location where materials need to be lifted. After lifting the materials, it can be pushed to any position. The angle between the two support arms is adjustable; in confined spaces, the angle can be reduced, allowing the mobile lifting frame to transport materials in narrow spaces. It is very convenient to use, significantly reducing the labor intensity of workers. The mobile lifting frame has a simple structure and is easy to inspect and maintain.

[0009] The present invention provides a lightweight mobile hanger in further detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0010] Figure 1 This is a structural schematic diagram of a lightweight mobile hanger according to the present invention; The following are the symbols in the attached diagram: 1-load-bearing wheel, 2-support arm, 3-pulley hook, 4-guide rope wheel, 5-wire rope fixing ring, 6-lifting arm, 7-push-pull handle, 8-wire rope, 9-worm gear reducer, 10-rotating handle, 11-rope winch, 12-base, 13-caster wheel. Detailed Implementation

[0011] like Figure 1 As shown, this utility model is a lightweight mobile lifting frame used for lifting materials or equipment. This utility model includes a base 12, a support arm 2, a worm gear reducer 9, a boom 6, and a wire rope 8.

[0012] like Figure 1 As shown, two support arms 2 are hinged to the rear side of the base 12 near the bottom. The two support arms 2 extend rearward respectively, and load-bearing wheels 1 are installed on the bottom surface of the rear side of each support arm 2. The included angle between the two support arms 2 can be adjusted. When space is limited, the included angle between the two support arms 2 can be reduced so that the mobile hanger can be moved freely in a narrow space. A caster wheel 13 is installed at the bottom of the base 12.

[0013] like Figure 1As shown, the worm gear reducer 9 is mounted on the front support platform of the base 12. The worm gear reducer 9 is an old piece of equipment salvaged and recycled from other discarded equipment. Since it is existing equipment, its structure will not be described in detail here. The output shaft of the worm gear reducer 9 is connected to the rope winch 11, meaning the output shaft of the worm gear reducer 9 is welded to the rotating shaft of the rope winch 11. When the output shaft of the worm gear reducer 9 rotates, the rope winch 11 also rotates, achieving the purpose of winding and unwinding the wire rope 8. The input shaft of the worm gear reducer 9 is connected to the rotating handle 10. Rotating the rotating handle 10 provides the driving power to the worm gear reducer 9. The bottom end of the boom 6 is connected to the base 12. The upper end of the boom 6 first extends vertically upwards and then backwards to the upper side of the two support arms 2. The bottom end of the wire rope 8 is wound around the rope winch 11. The upper end of the wire rope 8 first extends along the direction of the boom 6, then the wire rope 8 passes around the front end of the boom 6 and extends downwards to connect to the hook. Guide rope wheels 4 are installed at the top of the vertical section of the boom 6 and at the top of the rear end of the boom 6, respectively. The guide rope wheels 4 are used to guide the movement of the wire rope 8. A wire rope fixing ring 5 is also connected to the lower side of the rear end of the boom 6. In this embodiment, the hook is a pulley hook 3. When the wire rope 8 extends along the boom 6, it passes around the guide rope wheels 4 at the top and rear ends respectively, and then extends downwards to pass around the pulley hook 3. Then the wire rope 8 extends upwards to connect with the wire rope fixing ring 5.

[0014] like Figure 1 As shown, a push-pull handle 7 is connected to one side of the vertical section of the boom 6 to facilitate pushing and moving the lifting frame. The push-pull handle 7 is obliquely connected to one side surface of the vertical section of the boom 6 near the middle. When it is necessary to push and move the lifting frame, simply hold the push-pull handle 7 to pull the lifting frame forward.

[0015] During operation, first push the mobile lifting frame next to the material to be lifted, then reverse the handle 10 to release the wire rope 8 via the rope winch 11. The pulley hook 3 will then move down to the appropriate position to hook the material. Next, turn the handle 10 forward to wind up the wire rope 8 via the rope winch 11, and the pulley hook 3 will move up to lift the material. Once the material is at the appropriate height, lock the handle 10. Push the mobile lifting frame to the predetermined position using the push / pull handle 7, then reverse the handle 10 again to lower the pulley hook 3 to the ground and unload the material.
