Description

[Detailed Description of the Invention] The present invention relates to a vehicle body holder device for a lift used in automobile repair shops and other places.

Conventionally, for example, in a lift used to lift a car that has a protrusion such as an exhaust gas purification tank on the lower surface, when lifting the car body by a lifting arm extending laterally from the support, the protrusion is prevented from colliding with the arm. The vehicle body support receiving device provided at the tip of the arm is composed of a link lifting mechanism such as a bander bluff and a vehicle body receiving device provided at its upper end. That is, with the arm and receiver lowered, a car is driven into the arm, the tip of the bar is inserted into the underside of the receiver, the rear end of the bar is pushed down by the worker, and the receiver is pushed up using the principle of leverage. The upper surface of the receiver is pressed against the lower surface of the vehicle body, and then the lift is raised to lift the vehicle body. However, this conventional money receiving device has the disadvantage that a considerable amount of force is required by the operator to push up the money receiving device.

The purpose of the present invention is to obtain a money receiving device that eliminates such drawbacks, and its main components are an outer cylinder provided at the tip of the lifting arm, and a protrusion that comes into contact with the upper end surface of the outer cylinder. an inner cylindrical body having an inner cylindrical body at its upper end and capable of being inserted into the outer cylindrical body; a push-up cylindrical body removably provided at the lower end of the inner cylindrical body and capable of being inserted into the outer cylindrical body; It consists of a locking tool that locks the inner cylinder protruding from the upper end of the outer cylinder when it is inserted into the cylinder in its protruding state, and a receiver of the vehicle body provided on the upper surface of the protrusion.

An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a support column of the lift, 2 an arm that moves up and down along the support column 1, and an outer cylindrical body 3 is provided at the tip of the arm 2.

Reference numeral 4 denotes an inner cylinder, and the inner cylinder 4 has an outer circumferential diameter that allows it to be freely inserted into the outer cylinder 3, and has a protrusion 4a formed by protruding the upper end of its outer circumferential surface. At the same time, threads 4b and 4c are formed at the middle and lower end portions of the inner circumferential surface, respectively. 5 is car body A
The receiver 5 has a screw rod 5a protruding from its lower surface, and the screw rod 5a is screwed into the thread 4b. Reference numeral 6 indicates a push-up cylinder, and the push-up cylinder 6 has an outer circumferential diameter that is the same as that of the inner cylinder 4, and has an annular protrusion 6a projecting from its upper end surface. Thread 6b that can be screwed onto thread 4c
These threads 4c and 6b allow the push-up cylinder 6 to be detachably attached to the lower end surface of the inner cylinder 4.

Reference numeral 7 indicates a locking tool, and the locking tool 7 is formed in a U-shape as shown in FIG. I tried to make it wet. Note that reference numeral 9 indicates a bolt for adjusting the amount of push-up of the push-up cylinder 6.

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

As shown in the second figure, enter the car with the arm 2 lowered to the floor 10, then raise the arm 2 a little and place the push-up cylinder 6 on the lower surface of the inner cylinder 4 as shown in the third figure. Screw it on and lower arm 2 again. Along with this, the head of the bolt 9 of the push-up cylinder 6 hits the floor surface 10, and the push-up cylinder 6 pushes up the inner cylinder 4 so that it is inserted into the outer cylinder 3, and the inner cylinder 4 is pushed up. protrude upwards. Thus, no effort is required for this pushing up as in the conventional case. Then, the grooves 8, 8 of the inner cylindrical body 4 are exposed above the outer cylindrical body 3, and the locking tool 7 is engaged with the grooves 8, 8 as shown in the fourth figure. Therefore, the inner cylindrical body 4 is maintained in its protruding state. After that, the arm 2 is raised to lift the car body A to the state shown in the first figure for maintenance work.

Here, since the distance between the vehicle body A and the arm 2 is large due to the protrusion of the inner cylinder 4, the exhaust gas purification tank B, etc. on the underside of the vehicle body A does not hit the arm 2, and the tank, etc. is replaced and maintained. can be easily done.

After the maintenance work is completed, the vehicle body A is lowered by the reverse procedure described above.

Note that the means for attaching and detaching the push-up cylinder 6 and the inner cylinder 4 is not limited to that of the embodiment described above, and any means such as dovetail engagement may be used. It is optional, such as drilling a hole in the direction and inserting a wedge-shaped object into the hole.

As described above, according to the present invention, the push-up cylinder is attached to the lower surface of the inner cylinder, the arm is lowered, and the lower surface of the push-up cylinder is pressed against the floor, thereby forming the inner cylinder with the support for the vehicle body provided on the upper surface. Since it is made to protrude upward and the protruding state is held by a locking tool, it does not require any labor unlike conventional methods, and the exhaust gas purification tank, etc. protruding from the underside of the vehicle body can be used without hitting the arm. The vehicle body can be lifted up, the tank etc. can be easily replaced, and the structure can be simplified and the cost can be reduced.
