Channel type heavy vehicle lifting machine

Abstract

The invention discloses a channel type heavy vehicle lifting machine. The channel type heavy vehicle lifting machine comprises two platforms which are horizontally arranged in parallel, main legs arecorrespondingly installed below the two ends of the platforms, and the lower ends of the main legs are hinged to a base; sliding blocks are hinged to the upper ends of the main legs, sliding rails arearranged at the two ends of the platforms, and the sliding blocks are slidably installed in the corresponding sliding rails; and connecting rods are further hinged to the two ends of the platforms, the other ends of the connecting rods are hinged to the middle parts of the main legs, oil cylinders are hinged to the two ends of the platforms, and piston rods of the oil cylinders are connected to the middle parts of the main legs on the corresponding sides. The channel type heavy vehicle lifting machine has the beneficial effects that a large amount of auxiliary time can be saved, a vehicle canbe directly driven onto a guide rail platform, and thus the lifting and lowering operation can be carried out. The synchronous lifting and lowering control over the four parallel oil cylinders can berealized through a centralized control pump by being matched with a hydraulic electric control cabinet, the efficiency can be greatly improved, and repairmen in heavy vehicle repair plants can feel relaxed and convenient during working.

Description

technical field [0001] The invention relates to the technical field of lifting devices for automobile manufacturing and maintenance, in particular to a channel-type heavy vehicle lift. Background technique [0002] At present, most of the maintenance platforms for heavy-duty vehicle lifts are still based on the trench. The car is driven into the trench, and the maintenance personnel drill into the trench to perform various maintenance operations on the chassis of the vehicle. On the one hand, the cold and damp trench is not conducive to the health of the maintenance workers; on the other hand, such a dirty working environment makes the workers lose their dignity. In the past two decades, some international manufacturers have begun to provide ground lifts: purely mechanical or purely hydraulic multi-column lifts including screw nut drive, through real-time tracking and synchronous control to realize the control of heavy vehicles Steady lifting allows maintenance workers to c...

Problems solved by technology

In addition to the high economic cost, the main reason is that it is troublesome! After the car arrives at the station, it is necessary to move each column and push each tire, and then turn on the electric control system of each column to lift the car body to the required position through synchronous control; It takes a lot of time and effort to drive the car away only by dragging the uprights away from the tires! In the process of market research, it was learned through the research that the maintenance workers still hope to have a platform product that is closer to the trench, so that it will feel safer and more reliable when lifting the car
