Description

[Detailed Description of the Invention] The present invention relates to a lift device that is convenient for repairing a vehicle body that has been dented due to an accident or the like.

To repair car bodies that have been dented due to accidents, etc.
As shown in the first figure, the vehicle body a is lifted to a predetermined height by jacks, and then mounted on a mount, that is, a rigid track b, b.
Place the chain e of the traction device d on the recessed part c.
are connected, and the chain e is pulled by the pulling device d.
The recessed portion is pulled out through the .

However, according to this conventional repair method, in order to counter the traction by the traction device d, the vehicle body a must be towed from the opposite side by the traction device f via the chain g. In order to hold the vehicle in that state after lifting it with a jack, it is necessary to insert the rigid trucks b and b into the underside of the vehicle body a, which is time consuming and inefficient.

The purpose of the present invention is to provide a lift device for car body repair that eliminates such inconveniences and improves work efficiency.The main components of the present invention are to fix a base frame to the lower surface of the recess in the floor, and to A support base that fixedly supports the lower surface of the vehicle body is provided on a frame so as to be movable up and down, and when the support base is raised, a column that fixes and holds the support base in the raised position has one end attached to either the base frame or the support base. one corner of the support column, and the other end of the support column is latched to the other corner of the base frame or the support stand when the support column is in an upright state; It was arranged to abut against a stopper piece in the recess and hold it vertically.

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3.

1 is the floor of the workshop, 1a is a base frame fixed to the lower surface of the recess in the floor 1, 2 is a hydraulic cylinder buried in the center of the bottom of the recess, 3 is the plunger of the cylinder 2, and 4 is the plunger of the plunger 3. A cradle 5 provided at the upper end indicates a support pedestal placed on the pedestal 4, and the support pedestal 5 consists of bench frames 5a, 5a and cross beams 5b, 5b installed horizontally on the upper surface of the bench frames 5a, 5a. Clamps 6...6 are provided at both ends of the upper surface of these cross beams 5b, 5b. 7...
Reference numeral 7 indicates columns, and the roots of these columns 7...7 are rotatably connected to the four corners of the base frame 1a. Reference numerals 8...8 indicate stopper pieces erected at the four corners of the base frame 1a to hold the supports 7...7 when they are erected and placed in a vertical position.

Next, the operation of the above embodiment device will be explained.

The supports 7...7 are brought down as shown by dotted lines in FIG. 2, and the plunger 2 is lowered so that the pedestal 4 at its upper end is between these supports 7...7. 5 is placed in the state shown by the dotted line in FIG. Then, the automobile with the recessed body A is introduced above the support stand 5, and predetermined locations on the lower surface of the car body A are fixed by the clamps 6...6 of the support stand 5. Thereafter, the plunger 2 is raised, and the support base 5 lifts the vehicle body A to a predetermined height, and then the support column 7...
7 is erected, and the support base 5 is supported by the upper ends of the columns 7...7, and both are fixed with pins or other locking means. At this time, the struts 7...7 are the stopper pieces 8...8
is held in a vertical position. Then, the tip of a chain 10 of a traction device 9 consisting of a conventionally known hydraulic cylinder is connected to a dented part of the vehicle body A, and the part is pulled and repaired. Here, since the support base 5 to which the vehicle body A is fixed is held in a fixed state by the pillars 7...7, there is no need to tow the vehicle body A from the opposite side to resist towing as in the conventional case. During this work, the pedestal 4 is lowered as shown by the solid line in FIG. After the repair work is completed, the plunger 3 is raised to temporarily support the support stand 5 by the pedestal 4, and the supports 7...7 are lowered into the recesses of the floor 1, and then the plunger 3 is lowered, and the vehicle body A is lifted together with the support stand 5. Descend.

In the above embodiment, the columns 7...7 were pivotally connected to the base frame 1a of the floor 1, but on the contrary, the columns 7...
... 7 is pivotally attached to the support stand 5, and when the support stand 5 is in the lowered position, the support columns 7...7 are stored on the underside of the support stand 5, and when the support stand 5 is raised, the support columns 7...
... 7 may be suspended vertically and their lower ends may be locked and fixed to the base frame 1a. Further, the support stand 5 can be applied to any type of lift such as a one-post type lift, a two-post type lift, or a gate-type lift suspended from a ceiling rail.

As described above, according to the present invention, the support platform that fixedly supports the vehicle body is raised, and the columns that are pivotally connected at one end to the corners of the support platform or the base frame are brought into an upright state, and the other ends of these columns are connected to the base frame or the support frame. These pillars are fixed to the corners of the stand and kept in a vertical position by contacting the stopper pieces of the recess, so when pulling out a recessed part of the car body, there is no need to pull the part on the opposite side as in the conventional method. This eliminates the need to insert a frame such as a rigid truck under the vehicle body, thus improving work efficiency and eliminating the need for ordinary sheet metal work.
It can also be used as a lift device for inspection work, and has advantages such as a simple structure and low cost.
