[0003] However, in the elevator of Patent Document 1, the pivotal end and the sliding end such as the X-shaped connecting rod forming the upper lifting mechanism are connected to the upper surface of the cover plate, so even if the cover plate closes the pit opening surface, the X-shaped connecting rod The pivotal end and sliding end of the guide rail, etc., and the lower end of the guide rail may also protrude from the cover and become an obstacle to the operation.
In particular, in the type in which a pair of vehicle platforms are provided on the left and right and each vehicle platform is supported by an X-shaped link, from a cost point of view, there is a possibility that the two X-shaped links are not adjusted synchronously by a hydraulic mechanism, but by synchronous adjustment. The adjustment shaft connects the pivotal ends of the two X-shaped linkages to each other, thereby achieving synchronous adjustment, but in this way, since the synchronous adjustment shaft is also exposed from the cover plate, it causes the cover plate to close the pit. The effect is further reduced

Embodiment Construction
[0012] Embodiments of the present invention will be described below based on the drawings.
[0013] 1A, FIG. 1B, FIG. 2A, and FIG. 2B are explanatory diagrams showing an example of a lift for vehicle maintenance according to the present invention. FIG. 1A and FIG. The state when the loading platform is at the lower limit position. The vehicle maintenance elevator 1 includes a two-stage upper and lower elevator device 2 formed of a lower elevator mechanism 4 and an upper elevator mechanism 6 . This lower elevating mechanism 4 makes the elevating platform 3 provided at the upper end carry out lifting action in the pit 30 that is recessed under the ground F, and the upper elevating mechanism 6 is arranged on the elevating platform 3 of this lower elevating mechanism 4, so that the elevating platform 3 provided at the upper end The vehicle carrying platform 5 carries out lifting. A pair of lifting devices 2 are disposed on the left and right sides of the pit (the right side of F...

The subject of the present invention is to effectively close a pit when the lift is elevated. To solve the problem, an elevating / lowering means 2 comprises a lower elevating / lowering mechanism 4 for elevating and lowering an elevating / lowering stand 3 provided at an upper end, and an upper elevating / lowering mechanism 6 which is provided at the elevating / lowering stand 3 of the lower elevating / lowering mechanism 4 to elevate and lower a vehicle receiving stand 5 provided at an upper end. A cover 23 for covering the upper side of the elevating / lowering stand 3 except a shaft attachment end 19 and a sliding end 20 forming operational parts of the upper elevating / lowering mechanism 6 while its contour is matched with the opening surface of a storage part 31 is provided on the elevating / lowering stand 3 of the lower elevating / lowering mechanism 4. During the elevating operation of the elevating / lowering means 2, the opening surface of the storage part 31 is closed by the cover 23.
Description
technical field [0001] The invention relates to a lifter for vehicle maintenance, which lifts a vehicle carrying platform up and down through a lifting device arranged in a pit recessed under the ground. Background technique [0002] The lift for vehicle maintenance uses a lifting device to lift the vehicle platform up and down. The lifting device is composed of a driving device such as a hydraulic cylinder and an X-shaped link mechanism that performs telescopic movements in the up and down direction under the action of the driving device. In particular, In order to improve workability, etc., a vehicle maintenance lift is often used. The lifting device is installed in a pit recessed in the ground, and when the lift is lowered, the vehicle platform closes the opening surface of the pit so that it is flat relative to the ground. Regarding this elevator for vehicle maintenance, the applicant of the present application provided the invention of Patent Document 1 (JP Unexamined P...
