Carrying vehicle and hydraulic control system

Abstract

The invention discloses a carrying vehicle and a hydraulic control system. The carrying vehicle comprises a vehicle body, a door frame assembly, a rotating assembly, a holding and clamping assembly and a lifting assembly; the door frame assembly is vertically installed on the vehicle body and used for driving a rod-shaped object to ascend and descend; the rotating assembly is connected with the door frame assembly and used for driving the rod-shaped object to rotate in a vertical plane; the holding and clamping assembly is fixedly connected with the rotating assembly; and the lifting assembly is arranged on the holding and clamping assembly and used for bearing the rod-shaped object and providing additional lifting motion for the rod-shaped object, and the lowest point of downward motion of the lifting assembly is lower than the vehicle body. The lifting assembly capable of providing an additional lifting function for the rod-shaped object is arranged in the holding and clamping assembly, a hydraulic motor drives a reduction gearbox to move, a lifting guide rail is driven to move up and down along a shaft head fixing plate under the action of a gear and a rack, and finally a crystal bar on a tray is linked to move up and down; and due to the arrangement of the lifting assembly, the whole vehicle has an additional lifting function besides the portal assembly, the stacking height of the whole vehicle is greatly increased, and the adaptability of the whole vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of transport vehicle equipment, in particular to a transport vehicle and a hydraulic control system. Background technique [0002] With the continuous advancement of science and technology, the level of industrial production has also been continuously improved. Among them, the ingot industry has also developed rapidly. The domestic ingot production technology has continued to improve, which has greatly improved the production scale and product quality of ingots. In this context, More and more crystal ingot manufacturers are born. However, the crystal ingot production process needs to be processed by multiple procedures, and the crystal ingot needs to be transported. In the prior art, the ingot is transported manually, which increases the labor intensity of workers and reduces the cost.

Problems solved by technology

[0002] With the continuous advancement of science and technology, the level of industrial production has also been continuously improved. Among them, the ingot industry has also developed rapidly. The domestic ingot production technology has continued to improve, which has greatly improved the production scale and product quality of ingots. In this context, More and more crystal ingot manufacturers are born. However, the crystal ingot production process needs to be processed by multiple procedures, and the crystal ingot needs to be transported. In the prior art, the ingot is transported manually, which increases the labor intensity of workers and reduces the cost. Production efficiency, since the object to be transported is an irregular cylindrical crystal, for a crystal with a long size and a large weight, it is laborious to carry it by a single person, and it is easy to cause personal danger, requiring multiple people to work at the same time

[0003] Chinese Patent Publication No.: CN208747110U, discloses a single crystal silicon ingot handling mechanism, by setting the gripper, and the gripper is connected with the lifting mechanism and the rotating mechanism, can realize good handling to the crystal ingot, but the above-mentioned crystal ingot handling mechanism is in There are the following obvious deficiencies in the use process: the lifting of the grip is only realized by the lifting mechanism, and it does not have an independent lifting function. On the one hand, due to the size of the model, the lifting mechanism cannot be made very large, which makes the lifting height of the grip limited. It is not suitable for stacking crystal ingots with high dimensions; on the other hand, the lowest point of the lifting mechanism is the ground, and in the actual handling process, the lifting mechanism needs to be lowered below the ground so that the upper and top of the crystal ingots can be viewed by the staff , operation, however, the above-mentioned handling mechanism cannot be lowered to a height below the ground
