Description

Technical Field

[0001] The utility model relates to the field of new energy reducer transportation, in particular to a quick self-clamping lifting device for new energy reducers. Background Technique

[0002] The assembly of new energy reducers belongs to mass production in an assembly line mode, and special lifting devices suitable for the transfer of reducers are required to meet the short-beat assembly work. The reducer housing is made of aluminum alloy, and electronic components such as electronic oil pumps and temperature sensors are installed on the outside. If the current new energy reducer lifting device clamps too tightly, it is easy to bump the surface and damage the electronic components during the packaging and turnover transportation of the reducer assembly. If it clamps too loosely, there is a risk of the reducer assembly falling. Through retrieval, no technical solution identical to the present utility model was found, only some related comparative technical documents were found, mainly including the following:

[0003] 1. The patent with the application number 202021609458.4 discloses a self-locking lifting device, including two scissor fork devices arranged symmetrically left and right. The scissor fork device includes a first clamping rod and a second clamping rod, and the first clamping rod and the second clamping rod are hinged to each other through a second cross position; short shafts are hinged to the upper ends of the first clamping rod and the second clamping rod, and the two short shafts are hinged to each other through a first cross position; the upper ends of the two scissor fork devices are connected to each other through a first connecting shaft and a second connecting shaft, and the lower ends of the two scissor fork devices are connected by a connecting rod. A support plate for supporting the bottom of the box body is arranged inside the connecting rod. When the distance between the first connecting shaft and the second connecting shaft increases, the bottoms of the two scissor fork devices clamp inward simultaneously. This device not only clamps inward by gravity but also drives the two clamping rods to clamp inward by the elastic force of the spring, with good clamping effect and reduced risk of inability to clamp due to deformation and rust. However, this patent does not have a lifting ring and is not convenient for KBK lifting.

[0004] 2. The patent with the application number 202320551872.1 proposes a flipping lifting device with an anti-dropping function, including a connecting frame. A flipping lifting device main body is arranged outside the connecting frame, a fixing frame is fixed at the top of the flipping lifting device main body, and a flipping mechanism main body is fixed outside the flipping lifting device main body; this device is provided with an anti-dropping mechanism. When using the flipping lifting device main body and the flipping mechanism main body for clamping and lifting and flipping, the position of the anti-dropping housing outside the rotating frame can be adjusted simultaneously, and the anti-dropping housing limits and protects the clamping, lifting, and flipping processes, effectively avoiding the situation of dropping; this device is provided with an auxiliary stability mechanism. When using the flipping lifting device main body and the flipping mechanism main body for clamping, lifting, and flipping, the auxiliary stability pad can adaptively fit, which can not only increase the stability during the clamping, lifting, and flipping processes, but also the outside of the auxiliary stability pad is relatively smooth and wear-resistant during the flipping process and will not affect the normal flipping. However, the connecting frame structure of this patent is complex and not easy to operate.

[0005] 3. The patent with the application number 202023086087.9 provides a simple bracket sling, which includes a first sling ring, a C-shaped frame, a second sling ring, a third sling ring, a fourth sling ring, a first connecting plate with a hook, and a second connecting plate with a hanger. The first sling ring is connected to one end of the top of the C-shaped frame, one end of the bottom of the C-shaped frame is connected to the second sling ring, the second sling ring is respectively loop-connected to the third sling ring and the fourth sling ring, the third sling ring is connected to the second connecting plate with a hanger, the fourth sling ring is connected to the first connecting plate with a hook, and the first connecting plate with a hook and the second connecting plate with a hanger are hinged into a scissor-like structure. This simple bracket sling is simple, practical, easy to operate, and safe and reliable. Its structure is applicable to the hoisting of all current commercial vehicle balance suspension brackets, can reduce the labor intensity, improve production efficiency, and reduce production costs, and is suitable for popularization. However, this patent belongs to fixed clamping and cannot realize the function of automatically clamping objects.

[0006] Through the analysis of the above patent, it can be found that although the current self-clamping sling can adaptively clamp objects, it cannot be applied to new energy reduction gears with large weights. Therefore, the problems described above still exist, so it is very necessary to improve this. Summary of the Invention

The tension spring is arranged between the third combination pin and the fourth combination pin and can help the first clamping plate and the second clamping plate automatically clamp the assembly housing during the clamping process.

[0010] Furthermore, the first hook plate and the second hook plate are directly in contact with the assembly housing, and the material is aluminum, which can prevent the assembly housing from being scratched during the clamping process.
