Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically a modular lifting device. Background Technology

[0002] Lifting machinery, also known as hoisting equipment, is an important tool and equipment in industrial, transportation, and construction enterprises to realize the mechanization and automation of production processes, reduce heavy physical labor, and improve labor productivity. my country already has a large number of various types of lifting equipment. Although the number of lifting equipment used in university laboratories is not large and the lifting tonnage is not large, the maintenance and safe operation of these lifting equipment are even more important because of their low frequency of use.

[0003] Chinese patent CN221680650U discloses a material cart winch that uses a threaded connecting column to fix a pair of threaded fixed columns. This reduces the occurrence of the moving device entering the inner side of the fixed base column via a sliding column during the movement of the winch body. The overall device improves the ease of moving the winch body to the position where the heavy object needs to be towed. When the moving device does not need to be moved, the threaded connecting column is disengaged from the inner side of the threaded fixed column, allowing the sliding column and the moving device to enter the inner side of the fixed base column, with the bottom of the fixed base column firmly attached to the ground. The overall device reduces the poor moving effect caused by the large weight of the material cart winch during the movement to the position where the heavy object needs to be towed, and also reduces the occurrence of the winch with the moving device moving during traction work or when placed in a fixed position, resulting in poor traction effect.

[0004] While the above solutions improve winch stability by adding a support structure to the base and resting it against the ground, the winch body's height on the base creates a safety hazard during movement, such as the risk of collision. Therefore, we provide a modular lifting device to address these issues. Utility Model Content

[0022] I. This utility model achieves the switching between horizontal and vertical states of the lifting structure and the base through a rotating component.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figure 1-4 As shown, this utility model provides a technical solution: a modular lifting device, including a base 1, a lifting structure and a positioning component.

[0031] Both ends of the bottom surface of the base 1 are equipped with casters 2, which support the base 1. The base 1 can move on the ground by means of the casters 2. The casters 2 are designed with brake pads. The middle of the base 1 is provided with a through groove 3. The base 1 is provided with a rotating component and a limiting component for limiting the rotation component.

[0032] The lifting structure includes a frame 20 mounted on a rotating assembly, and the frame 20 is rotated by the rotating assembly to a horizontal or vertical position relative to the base 1.

[0033] In this embodiment, the rotating assembly includes a first support 5 mounted on the base 1, a first motor 6 mounted on the first support 5, and the output shaft of the first motor 6 mounted on the frame 20.

[0034] The output shaft of the first support 5 drives the first motor 6 to rotate, and the first motor 6 drives the frame 20 to rotate. The state of the frame 20 can be controlled, that is, the frame 20 is in a state parallel to the base 1, or the frame 20 is in a state perpendicular to the base 1.

[0035] The rotating assembly also includes a second support 7 fixedly connected to the base 1, and a support shaft 8 rotatably connected to the second support 7. One end of the support shaft 8 is fixedly connected to the frame 20.

[0036] The frame 20 is further supported by the support shaft 8 on the second support 7 to ensure the stability of the frame 20 in the rotation state.

[0037] In this embodiment, the limiting component includes a transmission disk 9 fixedly connected to the support shaft 8. The transmission disk 9 has slots 10 arranged in a circular array. A lifting plate 11 is provided above the transmission disk 9. A plug 13 is fixedly connected to the lifting plate 11, and the plug 13 matches the slot 10.

[0038] When the frame 20 rotates, it will drive the transmission disk 9 on the support shaft 8 to rotate synchronously. After the rotation is completed, the insert block 13 on the lifting plate 11 is inserted into the slot 10 to limit the transmission disk 9, thereby limiting the frame 20.

[0039] The limiting assembly also includes a fixed plate 14, on which two guide rods 12 are fixedly connected. The bottom end of the guide rods 12 is fixedly connected to the base 1. The two ends of the lifting plate 11 are slidably connected to the two guide rods 12 respectively. Springs 15 are sleeved on both guide rods 12, and the two ends of the springs 15 are fixedly connected to the fixed plate 14 and the lifting plate 11 respectively.

[0040] Under the elastic force of the spring 15, the lifting plate 11 can be elastically supported, thereby ensuring the stability of the upper block 13 after it is inserted into the slot 10.

[0041] A second motor 21 is installed on the frame 20. A rotating shaft 22 is installed on the output shaft of the second motor 21. A winding reel 23 is installed on the rotating shaft 22. The rotating shaft 22 is driven to rotate by the output shaft of the second motor 21, and the steel rope on the winding reel 23 is wound up and unwound, thereby completing the lifting of the object.

[0042] In this embodiment, the positioning component is disposed on the base 1 and is used to position the frame 20 in a state perpendicular to the base 1. The positioning component includes a support 16 fixedly connected to the base 1, an adjusting bolt 17 threadedly connected to the support 16, a movable plate 18 rotatably connected to the adjusting bolt 17, a positioning pin 19 fixedly connected to the movable plate 18, and an insertion hole matching the positioning pin 19 on the frame 20.

[0043] When the frame 20 is perpendicular to the base 1, the distance between the moving plate 18 and the support 16 can be adjusted by rotating the adjusting bolt 17, and the positioning pin 19 on the moving plate 18 can be inserted into the socket to complete the positioning of the frame 20.

[0044] A support block 4 is fixedly connected to the base 1, and a storage box 24 is fixedly connected to the base 1. The support block 4 and the storage box 24 are located at the two ends of the base 1 respectively. The support block 4 can support the frame 20 after it falls, while the storage box 24 can store miscellaneous items.
