Description

  The present invention is suitable for, for example, lift-up of a low-floor vehicle or an aero component-equipped vehicle, can be easily manufactured with a simple structure, can improve workability at the time of lifting set, and can realize subtle height adjustment. Related to lift attachments.

Among automobile enthusiasts, low-floor vehicles for the purpose of improving comfort and aero parts-equipped vehicles for the purpose of comfortable driving and steering are used.
Among these, some low-floor vehicles have the vehicle body floor surface greatly bulged downward, and when the vehicle is lifted up during the maintenance inspection, an attachment is attached to the mounting base, and the attachment is attached to the bulging portion. Positioning was performed avoiding contact, and a jack-up point on the vehicle side was positioned on the attachment (see, for example, Patent Document 1).

  However, some low-floor vehicles have various shapes and dimensions of the bulge, so it is necessary to prepare attachments of various shapes and dimensions according to them, and the jack-up point at the time of lift-up is high. There is a problem that the adjustment is complicated and time-consuming.

In order to solve such a problem, an outer cylinder is installed at the tip of the lift arm, the middle cylinder is screwed into the outer cylinder so as to be movable up and down, and the lifting and lowering unit integrated with the mounting base is inserted into the inner cylinder. There is a pedestal in which a support is slidably mounted and the support is biased upward by the elasticity of a spring.
When the cradle is used, the tip of the lift arm is moved to the jack-up point portion on the vehicle side, the cradle is pushed down against the elasticity of the spring, and this is released just below the jack-up point. The holding groove of the holding member on the pedestal is fitted into the side sill part, and at that time, the support plate is rotated to raise and lower the middle cylinder, and the height of the pedestal is adjusted precisely to enable lifting. (For example, refer to Patent Document 2).

  However, since the height of the cradle is adjusted by the elasticity of the spring and the screw mechanism of the intermediate cylinder, the range of adjustment is narrow and the accuracy is generally low. There is a problem that workability is poor due to the troublesome rotation operation.
