Description

Semi Scissor Type Lift}

The present invention improves the inclination of the uneven distribution of the scissor lifts, the inefficiency of space utilization of the four main lifts, and the inconvenience of the lateral movement of the scissor lifts. A semi scissor lift with all its advantages.

In general, a fixed cost lift is a device that helps the vehicle to easily maintain various kinds of failure factors by lifting the vehicle body off the ground after mounting the vehicle. Scissor Type).

Cross-link type (X-type or scissor-type) lifts are equipped with X-shaped cross links on the left and right sides of the pair of floor frames, respectively, and a vehicle mounting base on which the vehicle can be seated. . In addition, hydraulic cylinders are mounted to lift and lower the pair of cross links, respectively. Therefore, the hydraulic cylinder lifts and lowers the vehicle mounting stand on which the vehicle is seated while the cross link is raised and lowered.

In the case of scissor lifts, the wheels of the vehicle are located on the outside of the cross link, and the upper part of the cross link supports the vehicle mounting platform at two front and rear points, so if the vehicle is not located in the center of the vehicle mounting platform in the longitudinal direction, the weight is directed to one side. There is a problem that the mount is inclined in the longitudinal direction. Since typical lifts are used with small, medium and large vehicles, it is impossible to ensure that the center of gravity of the vehicle with different lengths is centered between the two front and rear supports of the crosslink. In addition, the scissor lift has a problem in that when the vehicle does not come in the middle of the vehicle loading stand and is moved toward one side, the load of the vehicle is concentrated on one side cross link and the vehicle mounting stand is inclined laterally. The on-board tilt of the scissor lift has a problem in that it is inconvenient for a job requiring horizontal precision such as wheel alignment work (for example, alignment work requires a precision of 0.01 °).

In addition, in the case of a scissor type lift, when a worker working in the lower part of the vehicle platform attempts to move laterally to replace a tool, the crosslink or the hydraulic cylinder for raising the link cannot be moved laterally, and the operator cannot move out of the lift. In case of exiting, there was inconvenience to move forward and backward of the vehicle.

Unlike the scissor type lift, the strut (particularly four-type) type lift has an advantage of preventing the tilting of the vehicle mounting by the uneven distribution of the weight of the vehicle and has excellent side mobility of the operator. However, since the strut type lift has to be installed wider than the width of the vehicle, and the four main type lift has to have the front and rear struts positioned at a distance longer than the vehicle's total length, the space found by the lift is large, which makes the space within the vehicle maintenance center more efficient. There was a problem that utilization is impaired.

An object of the present invention is to improve the inclination of the uneven distribution of the scissor lift, the inefficiency of space utilization of the four-wheel lift, and the inconvenience of moving the scissor lift, which has the advantages of the scissor lift and the four-wheel lift. This is to provide a semi scissor lift with advantages.

Another object of the present invention, unlike the scissor type lift that supports one vehicle stand at two intermediate points of the present invention is to support one vehicle stand at four outer points and even the four-wheel lift in case of uneven distribution of vehicle weight. Its purpose is to provide a semi scissor lift for vehicle work that requires almost 0.1 ° of precision, such as wheel alignment, because there are few inclined shapes.

It is another object of the present invention to provide a semi-caesar lift which improves the inefficiency problem of space utilization of a four-week lift that requires a lot of installation space because the precision is excellent and the space occupies the same as a conventional scissor lift. To do this.

Another object of the present invention is to provide a semi scissor lift having excellent workability by facilitating side movement of the operator by moving the lifting means outward unlike the conventional scissor lift.

The semi-caesar lift according to the present invention for achieving the object of the present invention, two parallel to the vehicle mounting stage 10, and one of the vehicle mounting base 10 in the front lower and rear lower symmetrical to each other 2 Four lifting means (100) for elevating the vehicle mounting table (10) and power means (200) for operating the elevating means (100);

The elevating means 100, the lower end is supported by the pin (P1) to the ground or the support 22, the upper end of the main link slidably supports the vehicle mounting table 10 through the operation link 40 20 and a shorter length than the main link 20, and an upper end thereof is connected to an outer-fixing pin P3 provided outside the vehicle mounting stand 10, and a lower end thereof is connected to the main link 20. It characterized in that it comprises a secondary link 30 is connected to the pin (P2).

A semi scissor lift with all its advantages is provided.

According to the present invention, unlike a scissor type lift that supports one vehicle stand at two intermediate points, the four-wheel lift is supported even when the vehicle weight is unevenly distributed by supporting one vehicle stand at four outer points. There is almost no inclined shape, and a semi scissor lift is provided for vehicles that require precision such as wheel alignment.

In addition, according to the present invention, as described above, the semi-caesar lift which has excellent horizontal accuracy and the same space occupied with the conventional scissor lift, which improves the inefficiency problem of space utilization of the four mold lift which requires a lot of installation space.
