Description

Lift for repairing vehicle

[technical field]

The present invention relates to the elevator that automotive servicing that its front end is equipped with the pivotal mounting that swing arm that vehicle bears platform can freely horizontally rotate with respect to the carriage along the pillar lifting is used, more particularly, relate to the limiting mechanism of the swinging arm of aforementioned swing arm.

[prior art]

This lift for repairing vehicle with swing arm by adjusting the angle of swing arm, goes for various vehicles.

For vehicle is lifted, at first, swing arm is reduced to lower limit, vehicle is left in this swing arm, then, vehicle is born platform adjust to angle under the hoist point, afterwards, carriage is risen, bear the position that platform and vehicle will soon contact up to vehicle, confirm that vehicle bears platform and hoist point matches, carriage is risen, reach specified height up to vehicle.

When promoting, the action of restriction swing arm makes it and can not optionally rotate, but when carrying out angular adjustment according to the difference of vehicle, must solve the restriction to its action, can freely rotate.

Thereby, for most vehicles, solving the adjustment that restriction makes the angle of operation that swing arm can move and arm under the unsettled posture of having to inwardly observe below the vehicle on side-looking ground simultaneously, operability is very poor.

Therefore, in the prior art, for example, as described in the public clear 53-33178 communique of spy, propose following scheme: with having with the pivot is the mating component of the arcuation auxiliary section of center fixation in swing arm, and on carriage and position that aforementioned mating component cooperates, the power of rubber-like directed downwards, the stationary member of liftable configuration constitutes the matching mechanism as the limiting mechanism of swing arm, when carriage drops to specified height, contact with platform from the hang down lower end of the drive pin that comes of stationary member, hoisting force works, stationary member breaks away from aforementioned mating component, the lift for repairing vehicle that matching mechanism automatically terminates, and, as described in the fair 7-86080 communique of spy, following scheme has been proposed: with being pivotally mounted to the locking lever in the swing arm and traversing the lockout mechanism of the mutual a pair of latch formation that oppositely along inclined direction loads of (trip is passed through) this locking lever loosely as the swinging arm limiting mechanism, when carriage drops to specified altitude, the latch-release plate that is arranged on highlightedly on the pedestal is inserted between the latch, resist loading force latch is strutted, automatically terminate the lift for repairing vehicle of lockout mechanism.

Although can improve operating characteristic but preceding a kind of lift for repairing vehicle, in order when promoting, not counteract the outstanding drive pin that to contract as much as possible downwards by the swinging arm limiting mechanism.

But when shortening drive pin, the effect of swinging arm restriction cancellation function only is limited in the scope that swing arm slightly upwards lifts from lower limit, therefore, swing arm is low excessively be difficult to vehicle bear platform correctly navigate to hoist point under.

In addition, a kind of vehicle maintenance of elevator in back, when carriage is dropped to its lowermost position, it should be noted that the front end that can not make the point of removing plate is from outstanding a lot of between the latch, so the same with the previous case, the effect of swinging arm restriction cancellation function only limits in the scope that swing arm slightly upwards lifts from lower limit, be difficult to adjust the angle of swing arm, in most of the cases can only be inadequate adjust.

The reason that these shortcomings exist is, any swinging arm restriction cancellation mechanism all sticks to and is arranged between carriage (swing arm) and the ground.
