Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a body support device of a mobile lift device used for lifting a vehicle in inspection and maintenance of the vehicle.

[0002]

2. Description of the Related Art As a conventional moving lift device, one fixed lift is provided at one end of an opening of a pit formed on a floor surface, and the other moving lift is movably provided along the opening. A large vehicle such as a truck enters the pit, stops the vehicle at a position where a front support point on the lower surface of the vehicle body is above the fixed lift, and then moves the mobile lift along the pit. And stops when the moving lift is located below a supporting point at the rear of the lower surface of the vehicle body of the vehicle, and raises and lowers the lifting rods of the fixed lift and the moving lift. Is known to lift the vehicle by contacting the vehicle.

[0003]

This conventional mobile lift apparatus is applied to lift-up of a large vehicle, and accordingly, the fixed lift and the mobile lift are formed to be large, and the mobile lift is fixed. Even when approaching the lifts, the lifting rods of these lifts cannot be brought close to the front and rear support points on the lower surface of the body of ordinary passenger cars and small passenger cars, and thus it is difficult to lift up these ordinary passenger cars and small passenger cars. was there.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problem and to provide a vehicle supporting device for a mobile lift device capable of supporting not only large vehicles but also ordinary passenger vehicles and small passenger vehicles.

[0005]

According to the present invention, there is provided a moving lift apparatus provided with a plurality of lifts in which at least one lift is movable at an opening of a pit formed on a floor to achieve the above object. A small and medium-sized support arm is detachably pivotally mounted on a support stand for a large vehicle body above the lift.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS.

FIG. 1 is a perspective view showing a state in which a passenger car A according to an embodiment of the present invention is being lifted, wherein 1 is a pit formed on a floor, 2 is a fixed lift, and 3 is a moving lift.

The fixed lift 2 is provided at the tip of the opening of the pit 1 and the movable lift 3 at the rear is movably provided along the opening. A large number of box-shaped lids 4 are provided on a continuous chain (not shown) connected before and after 3 to cover the opening, and the lid 4 has extremely high rigidity. Since it is supported by the ridges on both sides of the opening of the pit 1, it has high strength against load and prevents wheels and workers from falling.

In addition, since the cover 4 covers the downwardly entangled portion of the lid 4 in the pit 1, it is safe even if the vehicle tires fall on this portion.
A fixed cover 6 is provided on the side, and is opened at the time of maintenance in the pit 1 or the like.

Reference numerals 2a and 3a denote bearing stands for the lifts 2 and 3, respectively, and are fixed to the upper surface of a lifting rod 8 which is a lifting body of the lifts 2 and 3.

Reference numeral 7 denotes a bearing arm, and the bearing pedestal 2
a, 3a are detachably provided on the upper surface.

A two-dot chain line indicates a passenger car A such as an ordinary passenger car or a small passenger car.

In FIG. 2, the support arm 7 has an attachment / detachment portion 7a for attachment / detachment to the upper surface of the support receiving bases 2a, 3a, and an arm fulcrum 7b provided on the upper surface of the attachment / detachment portion 7a. The support arm 7 is pivotally mounted, and a support 7c for supporting the vehicle body is pivotally provided at the tip of the support arm 7. The support arm 7 swings around the arm fulcrum 7b and has a rectangular cross section. The frame bodies are fitted and formed so as to be able to expand and contract.

Reference numeral 7d denotes a positioning pin when mounted on the bearing supports 2a, 3a.

In FIG. 3, the bearing pedestals 2a, 3a
a is a frame formed by combining iron plates by welding or the like, and the lower mounting portions 2b and 3b of the bearing supports 2a and 3a are fixed to the upper surface of the elevating rod 8 by bolts. The upper part of 3a is formed in receiving frames 2c, 3c which are separated into right and left, and an auxiliary receiving device or the like for adjusting to the unevenness on the lower surface of the large vehicle body is attached.

The receiving frames 2c, 3c are provided with retaining ridges 2e, 3e at the upper and left and right ends.

First, as shown by the arrow, the attachment / detachment portion 7a of the support arm 7 is first lowered to the receiving frames 2c, 3c, and then moved to the left to insert and lock, and then another attachment / detachment of another support arm 7 is performed. After lowering the portion 7a, it moves to the right to be inserted and locked, and is formed as a pair by two right and left support arms 7, and the positioning pin 7d is formed.
Is inserted into the positioning holes 2d, 3d to determine the position. or,
When removing the bearing arm 7 from the bearing pedestals 2a, 3a, the order may be reversed.

Here, the mounting of the two bearing arms 7 individually on the bearing supports 2a, 3a can be reduced to a weight that can be handled by one worker with one bearing arm. Mounting work can be facilitated.

Next, the operation of one embodiment of the present invention will be described.

First, both lifts 2 and 3 are lowered to near the floor, and the movable lift 3 is moved to a predetermined position near the fixed lift 2 to stand by.

Next, when the passenger car A such as a normal passenger car or a small passenger car is lifted up, the support arm 7 is reduced to the shortest as shown in FIG. 4 and is opened close to 180 ° so that the vehicle width can be entered. Then, the passenger car A enters at right angles to the pit 1,
The support arm 7 is inserted under the vehicle body of the passenger car A as shown in FIG. 5, and each support arm 7 is adjusted by swinging or expanding and contracting so that the respective receiving members 7c face the respective support positions of the vehicle body. When the lifting rod 8 is raised to a predetermined height, FIG.
And maintenance work is performed at the ascending position.

Finally, the lifts 2 and 3 are lowered to return the support arm 7 as shown in FIG. 4, and then the passenger car A is moved to another place.

In order to carry out inspection and maintenance of the large car B after the passenger car A, the support arm 7 shown in FIG. 1 is removed, and an auxiliary support or the like adapted to the unevenness under the vehicle body is mounted on the support bases 2a and 3a. After mounting and moving the mobile lift 3 backward as shown in FIG. 6, the large vehicle B is lifted up.

As described above, the moving lift 3 is moved forward, and the bearing arms 7 are pivotally mounted on the bearing supports 2a, 3a, so that not only large vehicles but also passenger vehicles can be lifted up.

[0025]

As described above, according to the present invention, not only a large vehicle but also a vehicle such as a passenger car can be lifted up by pivotally mounting the bearing arm on the bearing support of the lift, so that the equipment cost can be reduced and the cost can be reduced. This has the effect of increasing the operating rate by adapting the vehicle type.
