Self-tracing lifting device with supporting frame

Abstract

The invention discloses a self-tracing lifting device with a supporting frame. The self-tracing lifting device comprises a walking mechanism and a lifting mechanism, and the walking mechanism comprises an AGV trolley; the self-tracing lifting device is characterized in that the lifting mechanism comprises the supporting frame and a lifting block connected to the supporting frame through a lifting driving device, two wheel supporting rods are fixed to the lifting block, and the lifting driving device is connected with an automatic controller in the AGV trolley to drive the lifting block to ascend and descend; and the supporting frame is installed on the body of the AGV trolley in a floating mode or rigidly fixed to the body of the AGV trolley or integrally arranged on the body of the AGV trolley, and the walking wheels are installed at the bottom of the body of the AGV trolley in a floating mode. When the lifting mechanism does not conduct lifting operation, the bottom of the supporting frame is suspended, and when the lifting mechanism conducts lifting operation, the bottom of the supporting frame touches the ground to provide support for lifting of the lifting block. The self-tracing lifting device can be put in places where automobiles need to be repaired, maintained or charged anytime and anywhere, a plurality of self-tracing lifting devices are combined for use to automatically lift the automobiles, and the lifting device is flexible and convenient to use, stable and reliable in bearing and high in working efficiency.

Description

technical field [0001] The invention relates to a self-tracking lifting device with a support frame. Background technique [0002] With the popularization of automobiles, in order to solve the problem of oil-to-electricity replacement of automobiles, the current solution is to use the battery replacement mode. Some existing car companies have launched a variety of battery replacement models. The batteries of this type of battery replacement model are usually installed on the bottom frame of the vehicle. Carry out the operation, that is, raise the vehicle through the facility to suspend the bottom frame, and then send the mechanical arm or the operating trolley under the frame to load and unload the battery. [0003] At present, the replacement stations for car battery replacement on the market have the same internal facilities for vehicle bottom work as the original facilities for ordinary car repair and maintenance. They are mainly divided into two types, namely, trenches ...

AI Technical Summary

Problems solved by technology

[0004] 1. It is too dependent on the site, occupies a large area, and is not flexible to use; since this type of trench or fixed lifting frame is a fixed facility on the ground, the supporting battery charging and storage and transportation facilities in the replacement station can only be integrated It is built and bound to each other, which requires a relatively open site, and is not suitable for construction in areas such as the city center with heavy traffic and land shortage, or narrow underground garages

[0005] 2. The known fixed lifting frame is often composed of a series of complex and precise mechanisms, which work together to complete a series of actions such as alignment, locking and lifting for the car. Difficult to disassemble and transfer, requires professionals to install and debug, expensive, high equipment maintenance costs

Moreover, a set of institutions only serves a single type of car, and the scope of application is very limited. In addition, some car companies have invested a lot in self-contained power stations, which cannot achieve high-density layout.

[0006] 3. The interior of the existing battery swap station usually only corresponds to one type of car, so there is no wheelbase and wheelbase problems when lifting and aligning. If it is to meet the needs of battery swapping for all vehicles, a complex mechanical structure must be added to the lifting device. Adapt to the wheelbase and wheelbase, even if it still puts forward quite high driving technical requirements for the driver to park in a precise fixed position

However, this lifting device is limited to the lifting and moving of the vehicle, and cannot be used for battery replacement or bottom maintenance of the car, and has the following disadvantages:

[0010] 3. Due to the need to carry and balance the forces in all directions at the bottom of the vehicle, the AGV trolley must also be equipped with a supporting balance and stabilization mechanism to provide a stable supporting force, resulting in a complex overall structure of the lifting device, inconvenient operation, and relatively low manufacturing and maintenance costs. higher

[0011] Therefore, there is no precedent for the application of AGV trolleys as vehicle lifting tools in the field of vehicle battery replacement.
