Four-post lifting machine for preventing car from slipping

Abstract

The invention discloses a four-post lifting machine for preventing a car from slipping. The four-post lifting machine comprises a bottom plate; stand posts are installed at vertex corner positions ofthe upper portion of the bottom plate; a screw rod is installed inside a threaded sleeve; one end of the screw rod is provided with a suction cup; mounting shafts are symmetrically mounted on the upper surface of a mounting plate; and a fixing clamp is installed on the outer surface of a mounting belt. The four-post lifting machine is scientific and reasonable in structure and safe and convenientto use, a tyre is clamped by the screw rod so as not to slip on a supporting plate, the suction cup at one end of the screw rod is sucked on a brake pad to ensure stability of the screw rod, and occurrence of safety accidents caused by slipping of the car on the supporting plate is reduced; and a tank body containing liquid and a tool are installed on the fixing clamp, the fixing clamp is pushed to make the mounting belt rotate around the sleeve, needed parts are selected according to overhauling requirements, and the problem that overhauling personnel continuously stoop to take the tools on the bottom plate and consequently the overhauling personnel cannot quickly overhaul or detect the car is solved.

Description

technical field [0001] The invention relates to the technical field of automobile machinery, in particular to a four-column lift that prevents automobiles from slipping. Background technique [0002] As the most commonly used travel tool for modern people, automobiles have broadened the scope of human travel and increased cultural exchanges between different geographical regions. The main components of automobiles include engines, chassis, body and corresponding electrical equipment. There are many uncontrollable factors in the car, and the various parts of the car are prone to damage. Regular maintenance can effectively avoid car accidents caused by damage to auto parts. Among the existing car repair tools, scissor lifts and pillars are commonly used Among them, the four-post lift has more support points at the bottom and the lifting process is stable, so the four-post lift is used as a lifting tool for large and medium-sized car maintenance, but the four-post lift on the m...

Problems solved by technology

[0003] The present invention provides a four-column lift that prevents automobiles from slipping, which can effectively solve the above-mentioned background technology. The four-column lifts currently on the market have a simple structure. Lift the pallet and the car, at this time the tires of the car cannot roll through its own braking, but when the position of the pallet is not adjusted properly, the car is prone to slip due to its own gravity, which will cause the vehicle to slide off the pallet The personal safety of the maintenance personnel is endangered. Because the cars lifted by the four-post lift are mostly large and medium-sized cars, their weight is relatively heavy, and the iron cables are prone to fatigue fracture damage after long-term use, and the iron cables have no obvious signs before fatigue fracture damage. , the existing four-post lift does not have an effective protection mechanism, and it is easy to cause injury to the maintenance personnel after the iron cable breaks. When the maintenance personnel perform maintenance under the supporting plate, they need to use more tools and place the toolbox on the bottom plate Maintenance personnel need to bend down to pick it up, which is not conducive to the maintenance personnel's rapid maintenance and inspection of the car. At the same time, when some tanks containing solution are placed on the bottom plate, they are easily kicked by maintenance personnel accidentally, resulting in leakage of the solution and damage to the bottom plate. Dirty, when the floor is dirty, the existing four-post lift cannot quickly clean the surface of the floor, which will easily cause debris to accumulate on the surface of the floor, which is not conducive to the construction of a high-quality workshop environment. During maintenance and inspection, because the car body blocks part of the light, it is usually necessary to use portable lighting fixtures for lighting. The existing four-post lift is inconvenient to fix the portable lighting fixtures, and it is also difficult to adjust the lighting light, which is not conducive to maintenance personnel Accurate Observational Maintenance Problems
