A two-column gantry with pneumatic unlocking

Abstract

The invention discloses a pneumatically unlocked two-column gantry, which comprises two upright housings and a lifting component, the lifting component is arranged on the inner surface of the upright housing, and the bottom end of the upright housing is fixedly equipped with a support base plate, The inner side of the column shell is longitudinally provided with a riser, and the upper ends of the two column shells are fixedly connected by a connecting beam; the lifting assembly includes a lifting shell, and the upper inner surface of the column shell is provided with a relief Shock assembly; the present invention uses a driving cylinder instead of the traditional wire rope pulling, so that the control of the driving cylinder can control the clamping or loosening of the switch of the limit clamp, thereby realizing the purpose of automatic control of safety opening and avoiding the shortcoming of the wire rope breaking; through Start the driving motor, and the worm gear and the worm are used together, so that the lifting component can rise and fall, and the lifting is convenient and fast, which is convenient for people to operate and use; the shock absorption component is provided to provide shock absorption for the lifting component, ensuring the service life of the lifting component .

Description

technical field [0001] The invention relates to the technical field of lifts, in particular to a pneumatically unlocked two-column gantry. 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 the ...

AI Technical Summary

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
