Abstract

PURPOSE: A double-post lift is provided to improve safety by alarming in advance with detecting unbalance in front and rear parts of a vehicle on the lift, and to increase working efficiency by preventing overturn of the vehicle. CONSTITUTION: A two-post lift is composed of a couple of posts installed vertically and faced to each other; a bar(3) installed parallel, and moved up and down in the posts; a support(5) installed in both sides of the bar to support the lower part of a vehicle; and an alarming unit detecting the change of the weight of the vehicle applied to the support, and warning overturn of the vehicle to an operator. The vehicle is loaded in the bar, and the support has a base plate(11) and a rubber support plate(13). The base plate is extended horizontally in the bar, and the support plate is restricted with a shock absorber, an elastic member(19) and a stopper(17). Safety is improved with alarming overturn of the vehicle by detecting the change of vehicle weight applied to the support. Working efficiency is increased with relieving uneasiness from overturn.

Description

2 post type lift}

The present invention relates to a two-stock lift, and more particularly, to detect and warn in advance the front and rear weight imbalance of the vehicle occurring on the lift in order to solve the safety of the use of the lift and anxiety due to the overturning of the vehicle to improve the work efficiency. It is about a two-stock lift.

In general, the maintenance of the car is performed on the lower side of the car body, so a lift capable of lifting the car body is required. Such lifts include four shares and two shares depending on the number of columns.

Compared to four stocks, two-stock lifts can be installed in narrow spaces and are often used for small car maintenance because of low installation costs. The two-stock lift is configured to support the lower part of the vehicle by four points using a pedestal provided to extend in the front-rear direction on each column.

If the front engine or transmission is removed or the rear rear axle is removed while the vehicle is lifted by the two-seat lift, front and rear weight unbalance of the vehicle occurs on the lift.

Due to the weight imbalance generated in this way, the two-stock lift may overturn the vehicle to the front or the rear during the work, thereby deteriorating safety due to the use of the lift and reducing work efficiency due to anxiety caused by the vehicle overturning.

Therefore, the present invention was created to solve the above problems, the object of the present invention is to detect the warning of the front and rear weight imbalance of the car in advance on the lift in advance to improve the safety of the use of the lift and anxiety due to the overturning of the car It is to provide a two-stock lift to solve the problem and improve work efficiency.

In order to realize this, the two-stock lift according to the present invention,

A pair of posts installed vertically opposite each other,

Bars are installed in parallel in the front and rear directions so that they can be lifted from the post,

Pedestal is installed to support the lower part of the car at both ends of the bar,

And warning means for detecting a change in weight of the vehicle acting on the pedestal and warning the worker that the vehicle is to be overturned.

BEST MODE Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a side view illustrating a state in which a car is lifted on a two-stock repeat according to the present invention, and includes a post 1, a bar 3, a pedestal 5, and a warning means.

The posts 1 consist of a pair and are provided opposite to each other in the vertical direction on the ground 7. And the pair of posts 1 have a vehicle width width between which the vehicle 9 can travel.

The bar 3 is installed to be elevated in each post 1, and is installed in parallel in the longitudinal direction, that is, the front-rear direction, of the vehicle 9 so that the vehicle 9 can be mounted thereon.

The pedestals 5 are provided at both ends of the bar 3 as described above, so that when the car 9 is mounted, the pedestal 5 can directly contact the lower part of the car 9 to support the car 9. As shown in the drawing, the base plate 11 and the support plate 13 are configured as main parts.

That is, the base plate 11 is formed to extend in the horizontal direction on the bar 3, the lower end of the shock absorber 15 and the stopper 17 is installed vertically on the upper surface thereof. The support plate 13, which is fixed to the upper end of the shock absorber 15 and whose operating range is limited by the shock absorber 15, the elastic member 19, and the stopper 17, is installed in the horizontal direction. The support plate 13 is preferably formed of a rubber in order to support the lower part of the vehicle without damage.

In addition, the warning means is configured to detect a weight change of the vehicle acting on the pedestal 5 according to the operation of the pedestal 5 as shown in FIG. 2 so as to warn the worker that the vehicle is to be overturned.

The warning means is composed of a switch 21 and a warning light 23 as shown in FIG.

The switch 21 is installed between the base plate 11 and the support plate 13 so as to be turned on / off by the support plate 13 which acts on the base plate 11 forming the pedestal 5. The switch 21 is turned on when the weight of the support plate 13 decreases when the vehicle 9 is about to be rolled over and the support plate 13 rises above a certain height by the elastic force of the elastic member 19. Such a switch 21 is preferably installed in each of the four pedestals 5 so as to operate a warning even when the vehicle 9 is rolled over or unbalanced from side to side. Do.

The warning lamp 23 constitutes a circuit with the switch 21 and the power source 25 to be turned on / off as one of the four switches 21 as described above is turned on / off. This warning light 23 can also be used effectively where there is noise, but can be replaced by a horn (not shown) where it is not.

When the vehicle 9 is overturned to the virtual line state (a or b) of FIG. 1 during the maintenance work by lifting the vehicle with the two-stock lift configured as described above, the switch provided in the rear or front pedestal 5 (21) is activated.

That is, in more detail, first, when the vehicle 9 is inclined, the weight acting on the support plate 13 on the side of the vehicle 9 that is heard is reduced.

The support plate 13 can no longer be lowered by the virtual line state c of FIG. 2, that is, the stopper 17 due to the elastic force of the elastic member 19 acting on the support plate 13 due to this weight reduction. It rises in the downward constraint state.

This causes the switch 21 to operate on and the warning light 23 or horn (not shown) to operate.

Therefore, the worker can know in advance that he wants to overturn the vehicle 9 by the light of the warning light 23 or the sound of the horn.

Therefore, the two-stock lift according to the present invention is provided with a warning means by detecting the weight change of the vehicle acting on the support for supporting the vehicle to warn the operator to try to overturn, thereby improving the safety of using the lift and overturning the vehicle It can improve work efficiency by relieving anxiety caused by.
