Hydraulic lifting mechanism of double-layer curing kiln

Abstract

The invention discloses a hydraulic lifting mechanism of a double-layer curing kiln. The hydraulic lifting mechanism of the double-layer curing kiln comprises a lifting mechanism and a shuttle bus forbearing plates. The hydraulic lifting mechanism of the double-layer curing kiln is characterized in that the lifting mechanism comprises a working face corresponding to a kiln door of the double-layer curing kiln, lifting guide rails arranged on the two sides of the working face, a lifting platform which is connected with the lifting guide rails and lifts the shuttle bus to the second-layer transverse guide rail, a hydraulic drive device driving the lifting platform to move along the lifting guide rail, wherein the working face comprises a first-layer transverse guide rail, a second-layer transverse guide rail and a pull device, the first-layer transverse guide rail and the second-layer transverse guide rail have different heights, and the pull device pulls the shuttle bus to move along the transverse guide rails; and the lifting guide rails are provided with limiting devices for limiting the lifting heights of the lifting platform, and the limiting devices correspond to the second-layer transverse guide rail in height. The hydraulic lifting mechanism of the double-layer curing kiln is relatively good in overall running stability, the production efficiency is advantageously improved, and operation can be completed only with the two lifters on the two sides.

Description

technical field [0001] The invention relates to the technical field of plate production, in particular to a hydraulic lifting mechanism for a double-layer curing kiln. Background technique [0002] At present, in the production process of environmentally friendly boards, the boards pressed in the formwork need to enter the curing kiln with specific humidity and temperature for curing to ensure the final quality of the boards. [0003] In the existing curing kiln design, in order to effectively use the space, reduce the floor space, improve work efficiency, etc., a double-layer or multi-layer curing kiln design will be adopted. When using a double-layer curing kiln, it is necessary to use a lifting mechanism to lift the plate to a predetermined height before sending it into the curing kiln. [0004] However, the existing lifting mechanism has the problem that the lifting accuracy is not high, and after multiple liftings, the stroke is prone to deviation. Especially in the c...
