Pneumatic unlocking two-column gantry

Abstract

The invention discloses a pneumatic unlocking two-column gantry. The pneumatic unlocking two-column gantry comprises two stand column shell bodies and lifting assemblies; the lifting assemblies are arranged on the inner side faces of the stand column shell bodies; supporting plate assemblies are fixedly installed at the bottom ends of the stand column shell bodies; vertical plates are arranged onthe inner sides of the stand column shell bodies in the longitudinal direction; the upper ends of the stand column shell bodies are fixedly connected via a connecting horizontal beam; each of the lifting assemblies comprises a lifting shell body; and shock absorption assemblies are arranged on the inner surfaces of upper sides of the stand column shell bodies. According to the pneumatic unlockingtwo-column gantry, a driving air cylinder replaces a traditional steel wire rope for pulling, so by controlling the driving air cylinder, a switch of a limiting clamping plate is controlled to be clamped or loosened, the purpose of automatic control safe opening is realized, and the defect of breakage of the steel wire rope is avoided. Through initiating a driving motor and via coordinated application of a turbine and a worm, lifting and descending of the lifting assemblies are realized in a convenient and rapid mode, and operation and use by a user are convenient. Through the arrangement thatthe shock absorption assemblies provide shock absorption for the lifting assemblies, the service life of the lifting assemblies is guaranteed.

Description

technical field [0001] The invention relates to the technical field of lifts, in particular to a two-column gantry with pneumatic unlocking. Background technique [0002] With the continuous development of society and the continuous improvement of people's living standards, automobiles have begun to enter thousands of households, so the automobile maintenance industry is also developing rapidly, and the frequency of automobile maintenance is also increasing. It is an indispensable part of automobile maintenance. The equipment is the gantry lift. The gantry lift refers to the car maintenance equipment used in the car maintenance industry for car lifting. The lift plays a vital role in car repair and maintenance, whether it is a complete vehicle overhaul or a minor repair. , are inseparable from it, and the nature and quality of its products directly affect the personal safety of maintenance personnel. Almost all side shops are equipped with lifts, and car lifts are one of th...

Problems solved by technology

[0004] The purpose of the present invention is to provide a two-column gantry with pneumatic unlocking. By driving the output rod of the cylinder to extend or retract, the limit clamp is driven to rotate around the clamp shaft, so that the distance between the limit clamp and the column housing The card slot on the inner surface is snapped or loosened, so that the lifting component remains locked or active. The device uses a drive cylinder instead of the traditional wire rope to pull, so that the control of the drive cylinder can control the switch of the limit clamp to snap in or loosen. Opening, so as to realize the purpose of automatic control safety opening, and avoid the shortcoming of wire rope breakage by driving the cylinder control; the present invention uses the combination of starting the drive motor and the worm wheel and the worm, so that the lifting assembly rises and falls, and at the same time, the lifting shell The inside of the body is equipped with a pulley, which slides and cooperates with the chute on the surface of the vertical plate, thereby reducing the friction force during the lifting process of the lifting component, and the lifting is convenient and fast. The whole process adopts an automatic lifting method without human assistance, which is convenient for people to operate and use. Provide shock absorption for the lifting component by setting a shock absorbing component on the inner surface of the upper side of the column housing, and by setting a fixed plate above the drive motor, so that when the lifting component rises, it is avoided. The wall is collided to cause damage, thereby ensuring the service life of the lifting component; by opening a leg through groove on the bottom surface of the first leg, setting the second leg under the first leg, and at the same time setting the second leg in the leg through groove The inner side of the gantry lift is supported by the first leg and the second leg at the same time, which ensures the stability during work. The second leg can be retracted into the leg slot, which is more convenient to use and carry, and solves the problem of using the two-column gantry lift. The medium wire rope is easy to stretch, and the maintenance frequency is high, which may easily cause the problem that the insurance cannot be opened and is easy to break
