Linkage system based on multiway hydraulic control valve

Abstract

The invention discloses a linkage system based on a multiway hydraulic control valve. The linkage system comprises a multiway hydraulic control valve for being connected with operating oil paths of a plurality of hydrocylinders in a switching manner, wherein a travel bracket is connected onto a piston rod of each hydrocylinder; a travel collision block and a first opener are arranged on the travel bracket; rotatable rocker arms are arranged between the multiway hydraulic control valve and the travel brackets; a movable collision block positioned between each travel collision block and each first opener is arranged on each rocker arm; a reversing poking plate and an opener fixing plate are arranged on each rocker arm; each reversing poking plate is connected with a reversing valve core; a second opener provided with a valve core opposite to a switching valve core is fixed on each opener fixing plate. According to the linkage system provided by the invention, an oil-path system is controlled through the multiway control valve, so as to control the hydrocylinders to operate, and the full-automatic control on the hydrocylinders is realized through the cooperation of the linkage system; the linkage system has a simple structure, ideal synchronicity, accuracy and reliability, and can realize remote mechanical transmission automation.

Description

technical field [0001] The invention relates to a control device, in particular to a linkage device based on a multi-channel hydraulic control valve. Background technique [0002] In modern times, industrial automation has been widely used in production, and some production equipment has realized fully automatic or semi-automatic operation, which saves labor and improves production efficiency. In the existing automation equipment, numerical control or relays are generally used to realize automatic control. Among them, the numerical control automation equipment has the advantages of convenient operation, stable performance and high efficiency, but the cost of the existing numerical control equipment is generally tens of times higher than that of ordinary equipment. times, there are disadvantages of high cost and difficult maintenance; and the equipment that uses relays to realize automation has low cost, high efficiency, and is easy to replace and maintain, but because the re...

Problems solved by technology

In the existing automation equipment, numerical control or relays are generally used to realize automatic control. Among them, the numerical control automation equipment has the advantages of convenient operation, stable performance and high efficiency, but the cost of the existing numerical control equipment is generally tens of times higher than that of ordinary equipment. times, there are disadvantages of high cost and difficult maintenance; and the equipment that uses relays to realize automation has low cost, high efficiency, and is easy to replace and maintain, but because the relay is prone to failure, the performance of the equipment is unstable and safe. The coefficient is also lower

[0003] Hydraulic power systems are widely used in industry and construction. Existing hydraulic power systems can be controlled by numerical control devices and / or relays, but there are still problems in terms of cost, performance or safety mentioned above; at the same time, numerical control devices and relays are both Restricted by the use environment, it cannot be used normally in some harsh environments, and the hydraulic power system is often used in harsh environments, so it cannot be automatically controlled by the above-mentioned numerical control equipment and relays, and manual control is required
