Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for attaching / detaching an automobile engine, a mission or the like to a vehicle body.

[0002]

2. Description of the Related Art The repair of the interior of an automobile engine and mission and the frequent replacement of clutch discs and the like are performed by removing the engine and mission from the vehicle body. Since the engine and the mission are very heavy, a special detaching machine is used for their attachment and detachment. However, among various operations in vehicle maintenance, there is no work as complicated and dangerous as this attachment and detachment work.

Particularly in recent years, the ratio of front engine / front drive vehicles (FF vehicles), which emphasizes habitability and the like, has rapidly increased in place of conventional front engine / rear drive vehicles (FR vehicles). The problem of the work of attaching and detaching the engine and the like is particularly great in such FF vehicles. In other words, in the case of FR vehicles, the engine is located in the engine room, the mission gear is under the floor, and the differential gear is under the rear trunk. It is not difficult and there is little danger in work. On the other hand, in the case of FF vehicles, the structure is such that the mission gear and the differential gear are packed in addition to the engine in the narrow space of the engine room where only the engine is originally stored, so it is very difficult to attach and detach the engine and the mission. However, the danger is also great.

Conventionally, as a desorption machine, a trolley system equipped with a lifting means such as a chain block has been used.
This desorption machine is placed on the work floor independently of the lift of the automobile, and the lifting means lifts the engine and mission, and the wheels move on the work floor so that the engine and mission can be carried in and out of the vehicle body. ing.

[0005]

Conventionally, when removing an engine and a mission from the body of an FF vehicle by using such a desorption machine, the body is placed on a lift and the parts and bolts are removed from the engine room and under the floor. After that, lower the lift to the position where the desorption machine can be set on the engine. Then, set the lifting means of the desorption machine located on the work floor near the lifting lift to the engine and mission, and then remove the several bolts for temporary fastening that support the engine and mission to the vehicle body, and remove the desorption machine. Lift the engine and mission with and take it out of the vehicle.

However, when removing the engine or the like, the heavy engine and the vehicle body with the mission removed become lighter by that amount, so that the lift for supporting the same tries to bounce upward, while the removable machine Tries to move downward due to the weight of the engine, etc., and such contradictory movements occur in the narrow engine room, so the work is very dangerous, and the work should be done in consideration of such movements. There is the difficulty of having to do it. For this reason, there are many accidents in this kind of desorption work, and there is a big problem that the work itself takes time.

Further, in the detachable machine as conventionally used, when the lifting means is once set to the engine and the mission when the engine and the mission are removed, the vehicle body can be lifted and lowered by the lifting lift. Even if you forget to remove one bolt, you have to remove the desorption machine and go back to the place where you install the bolts that support the engine and the mission. There was a problem of being bad.

The present invention has been made in view of the above conventional problems, and an object thereof is to provide a device capable of safely attaching and detaching an engine and a mission with good workability.

[0009]

SUMMARY OF THE INVENTION In the present invention, the conventional problems as described above are solved by the attachment / detachment machine independent from the lifting / lowering lift of the vehicle body.
Focusing on the fact that it does not move in the same manner as this, the present invention has devised a desorption device that can perform a lifting operation integrally with a lifting lift.

A lifting device detachably attached to an arbitrary mounting portion, the lifting device including a vertically movable hoisting arm having a power mechanism for hoisting an engine or the like. The detaching device is characterized in that a main body or a lifting arm constituting the main body can be horizontally swung.

[0011]

In the attachment / detachment device of the present invention, the hoisting device is attached to an arbitrary attachment portion of the turning arm according to the position of the engine or the like of the vehicle body. The swivel arm can swivel horizontally using the hoisting part of the hoisting lift or / and its longitudinal middle part as a fulcrum, and the hoisting arm equipped with a power mechanism for hoisting an engine or the like can vertically swivel. Further, the main body of the hoisting device or the hoisting arm constituting the hoisting device main body is horizontally rotatable. Therefore, the engine and the mission suspended by the lifting arm can be moved in any of the up-down direction, the front-rear direction, and the left-right direction with respect to the vehicle body.

Further, since the apparatus of the present invention moves up and down together with the lifting portion of the lifting lift, it is possible to lift the lifting lift while the engine and the mission are being lifted, and the lifting position of the lifting portion is independent of the lifting position. The suspended engine or mission can be moved in any of the above directions.
