Lifting device for shift carrying

Abstract

The invention provides an elevating gear for movement, which is capable of shortening field installation or movement period, and of bringing forward running. The elevating gear comprises a rack (2) fixed on the floor (FL); and a plurality of struts (3) stretched upwards and downward, each of which is composed of a fixing strut (4) extending upwards and a lifting strut (4) sliding upwards and downward relative to the fixing strut (4). By a drive unit, the struts are stretched and a workpiece support tool (6) of the lifting strut (5) is lifted, thus realizing movement between transporters (C1, C2) having different heights. Since the whole height is lower than a lift when the struts (3) are contacted, the elevating gear can not interfere with other apparatuses (FR) even if moved in the state. According to the invention, an elevating gear (1) for movement is assembled and adjusted in a manufacture factory and then delivered, and is installed in field.

Description

technical field [0001] The present invention relates to an elevating device for transfer, which transfers between conveyors having height differences by raising and lowering a workpiece support tool supported by a pillar by a drive device. Background technique [0002] As an existing lifting device for transfer, there are devices such as the following: For example, as described in Patent Document 1, a pair of sprockets are arranged above and below the pillar, the rotation axes of the pair of sprockets are horizontal and parallel to each other, and An endless chain driven by a motor is wound around the wheel, and one of the base end portion and the middle portion of the length of the arm provided with the workpiece supporting tool at the movable end is an elevating member that can slide freely only in the up and down direction with respect to the above-mentioned support. connected, and another passing shaft is connected to the above-mentioned endless chain, as the path of the...

Problems solved by technology

[0006] In the schemes of Patent Documents 1 and 2, since the column length (pillar height) above the head is required, it is easy to interfere with other equipment in the factory in the assembled state, especially when moving heavy objects such as automobile bodies. In the case of loading, it is difficult to shorten the installation or relocation period and operate early because it requires on-site assembly and on-site installation of auxiliary beams, cantilevers, inspection platforms, and ladders, etc., and requires more man-hours for installation and relocation. needs

[0007] Moreover, according to the proposal of Patent Document 1, after the stand is fixed on the ground with anchor bolts, fine adjustments in the horizontal direction and in the vertical direction cannot be performed. Spend time

[0008] Moreover, according to the proposal of Patent Document 2, the wheels and the adjuster are installed under the feet of the base, so the adjuster can be protruded after being moved by the wheels to install the device on the ground, but since the direction in the horizontal plane and the up and down Fine adjustment of the direction, so from this point of view, the adjustment work at the time of installation and relocation also takes time
