As shown in fig. 1 to 4, a fast-acting hydraulic control integration apparatus 1 corresponding to an embodiment of the present invention is a modular integrated arrangement and integrally mounted directly above a hydraulic cylinder 5 having a self-resetting function for controlling the operation of the hydraulic cylinder 5. The quick acting hydraulic control integration device 1 comprises a valve body 10, a regulating valve group 20 and a quick acting valve group 30 which are mounted on the valve body 10 and are mutually matched.

With further reference to fig. 5-8, the valve body 10 has a block-like structure and includes a main body 101 and a positioning portion 103 fixedly connected to each other, and of course, the main body 101 and the positioning portion 103 may be integrally formed. An oil inlet P and an oil outlet T are provided on one side 11 thereof. The oil inlet P and the oil return port T are both communicated with a hydraulic oil station (not shown) and three oil path pipelines including a large oil path pipeline 12, a medium oil path pipeline 14 and a small oil path pipeline 16 are also arranged in the valve body 10, and the three oil path pipelines 12, 14 and 16 are all mutually communicated with the oil inlet P and the oil outlet T. Corresponding to the embodiment of the invention, the diameters of the three oil way pipelines 12, 14 and 16 are 6mm, 16mm and 40mm respectively, and the corresponding flow rates are respectively smaller than 20L/Min, larger than or equal to 20L/Min and larger than or equal to 1600L/Min. Furthermore, an oil inlet a and an oil outlet B are provided on the bottom surface 13 of the valve body 10. The oil inlet P, the oil outlet T, the three oil way pipelines 12, 14 and 16, the oil inlet A of the oil cylinder and the oil outlet B of the oil cylinder are all mutually communicated. In addition, the valve body 10 is fixedly mounted on the hydraulic cylinder 5 through a fastener (not shown), and the cylinder oil inlet a and the cylinder oil outlet B on the valve body are aligned and communicated with the oil inlet channel A1 and the oil outlet channel B1 arranged on the hydraulic cylinder 5, so that the circulation of liquid can be realized without configuring additional oil pipe fittings and the like.

With further reference to fig. 9-10, the regulator valve block 20 basically includes a first electromagnetic directional valve F1, a proportional valve F2 and a plurality of check valves D3, D4, D5. The first electromagnetic directional valve F1 and the proportional valve F2 are each installed on the top surface 15 of the valve body 10 at a distance from each other, and are connected to the corresponding oil path pipe through corresponding openings (not numbered) provided on the top surface 15. The plurality of check valves includes a first check valve D3, a second check valve D4, and a third check valve D5, which are inserted into corresponding openings (not numbered) provided on the side of the valve body 10 to be connected to corresponding oil path pipes. Specifically, the first electromagnetic directional valve F1 is directly connected to the oil inlet P of the hydraulic station, and two ports of the first electromagnetic directional valve F are respectively connected to the first and second check valves D3 and D4. The proportional valve F2 is connected to three check valves D3, D4, D5 simultaneously.

The pressure gauge B2 is arranged on the small oil way pipeline 16, and can check the oil inlet pressure condition of the integrated device 1 in real time. In addition, the fast-acting hydraulic control integrated device 1 is further provided with two expansion interfaces CY1 and CY2 which are respectively arranged on the small oil way pipeline 16 and the large oil way pipeline 12, and can be used by customers (accessories such as a pressure sensor, a pressure measuring joint and the like can be connected in) to better monitor the use condition.

Fig. 11 is a schematic structural diagram of the integrated device 1 of the present invention. The working principle and process of the integrated device 1 are as follows: after the electromagnetic reversing valve F1 of the regulating valve group 10 is firstly electrified and reversed, pressure oil from a hydraulic oil station enters the first hydraulic control one-way valve D3 and the second hydraulic control one-way valve D4 through the oil inlet P on the valve body 10, the two one-way valves are opened, at the moment, one end of the proportional electromagnetic valve F2 is electrified and is connected into an oil way pipeline to communicate the oil inlet P with the oil inlet A of the oil cylinder, at the moment, the pressure oil inlet and the oil discharge of the end of the oil inlet A of the oil cylinder are regulated by controlling the proportional electromagnetic valve F2, and the stop of any position of an actuator unit of the oil cylinder 5 is realized. If the other end of the proportional solenoid valve F2 is electrified, the oil inlet A of the oil cylinder is communicated with the oil return opening T, and hydraulic oil returns through the one-way valve D5 to release pressure, so that the function of regulating the movement of the cylinder body is realized. In the power-on state of the electromagnetic directional valve F3, hydraulic oil passes through the electromagnetic directional valve F3 to enable the hydraulic two-way cartridge valve F4 to be closed, so that the oil inlet A of the oil cylinder is not communicated with the oil inlet B of the oil cylinder, and the oil cylinder 5 normally operates; when pressure relief is needed, the second electromagnetic directional valve F3 is powered off, so that the hydraulic two-way cartridge valve F4 is opened, and the oil cylinder oil inlet A, B and the oil return port T are mutually communicated, so that quick pressure relief action of hydraulic oil is realized.

As can be seen from the above description, the fast-acting hydraulic control integrated device 1 provided by the present invention at least includes the following advantages: firstly, by arranging the regulating valve group 20 and the quick action valve group 30, not only the flow and the pressure of the liquid can be regulated and controlled, but also the use requirement of quick action is met; secondly, the integrated device 1 has an integral modularized structure, not only parts of the integrated device are integrally connected to the valve body 10, but also the integrated device is directly communicated with the oil inlet channel A1/the oil outlet channel B1 of the oil cylinder 5 through the oil inlet A/the oil outlet B, and the oil way pipelines 12, 14 and 16 arranged inside the integrated device are directly integrally formed on the valve body 10 without additional arrangement of pipelines or pipelines, so that the occupied space of the whole device is small, the assembly and the disassembly are convenient, and the environmental pollution is small; and the integrated device 1 is further provided with a pressure gauge B2, a plurality of expansion interfaces CY1 and CY2 and the like, can monitor the whole equipment in real time, and has the performance advantages of quick response, stable and reliable work and high efficiency.
