An automatic locking release and lifting device for power failure retention and its realization method

Abstract

The invention discloses a device and an implementation method of power-off maintenance automatic locking-releasing and lifting. The device is arranged in battery weight impact test equipment which is provided with a weight platform deck, wherein the device comprises a base plate which is arranged in parallel with the weight platform deck, the base plate and the weight platform deck are arranged on a plurality of slider bars in parallel, a crank hook extending downwards is further arranged on the base plate and is matched with a hook seat cross bar arranged on the weight platform deck in a hooking mode, a hinged shaft of the crank hook is arranged on the base plate, and the upper end of the crankshaft is capable of moving forward and downward through the control of an electromagnet. According to the device as well as the implementation method and equipment of the power-off maintenance automatic locking-releasing and lifting, due to the fact that the crank hook is controlled to be open and closed, locking and releasing of the whole weight platform deck are achieved, safe locking of the whole weight platform deck can be achieved when power is off, the situation of accidental damage is prevented, automatic control of height adjustment of the weight platform deck can be achieved, the structure is simple, and the device is convenient to use and capable of being automatic.

Description

technical field [0001] The invention relates to a battery weight impact testing device and a method thereof, in particular to an automatic locking structure improvement device of the battery weight impact testing device and a realization method thereof. Background technique [0002] In the automatic mechanical equipment in the prior art, especially in the mechanical devices that need to lift weights, the product needs to be automatically locked and released when lifting and releasing heavy objects. If the heavy objects are not released in time after lifting, once a broken In the case of electricity, there may be a risk of heavy objects falling, which may cause damage to the equipment, and may cause casualties. Therefore, it is necessary to prevent this accident, so it is necessary to design the mechanical power-off protection function for the action mechanism of the mechanical equipment. [0003] The invention mainly aims at improving the battery weight impact test equipmen...

AI Technical Summary

Problems solved by technology

The lifting structure of the electromagnet may encounter a power outage during the lifting process. Once a power outage occurs, due to the lack of protection from the automatic locking mechanism, the heavy object carrier will immediately fall, resulting in personal injury and scrapping. HAZARDS OF PRODUCT OR DAMAGED EQUIPMENT

[0006] 2. Due to the actual test, it is necessary to simulate the falling of heavy objects of different heights. However, when the heights of the test heavy object platforms are different, the height of the blocking cylinder must be manually adjusted immediately. If it is necessary to carry out alternate tests of different heights at the same time, Frequent manual operations cannot automatically complete the testing process and fail to meet the automation requirements of actual production

[0007] Therefore, there are the following problems in the battery weight impact test equipment of the prior art: 1. When different products need to release the heavy object carrier from different heights, it takes time to manually adjust the horizontal cylinder, which is inconvenient for different height requirements of different products. test

2. If the power is cut off during the lifting process of the heavy object carrier, because there is no protective structure, the heavy object carrier will fall down, which may cause accidents, and the product to be tested may also be scrapped if it does not meet the test conditions

3. An air source mechanism is added to the action structure. If the air source fails, when the heavy load carrier reaches the top of the lifting stroke, the cylinder cannot move in time, which will affect the effect of the protection function.

In addition, the horizontal cylinder is subjected to radial force, which violates the traditional use of cylinders. It needs to be configured with a large bore and has a limited service life, which greatly increases production costs.
