Description

Technical Field

[0001] This utility model relates to the field of crane accessories technology, and in particular to an intelligent hydraulic control device for crane luffing. Background Technology

[0002] A crane is a mechanical device used for vertically lifting or horizontally moving heavy objects. It is widely used in construction, ports, factories and other fields. When using a crane, an intelligent hydraulic control device for boom luffing is required to control the hydraulic system. This intelligent hydraulic control device is a high-end device that integrates sensor technology, intelligent algorithms and hydraulic control. It is used to precisely adjust the pitch angle of the crane boom. It is mainly used to optimize the motion stability and operating accuracy of the crane's luffing mechanism. It can control the capacity of the hydraulic oil inside the hydraulic cylinder to control the efficiency and intensity of the hydraulic pressure.

[0003] Modern crane luffing intelligent hydraulic control devices can basically meet people's needs, but there are still some problems, as follows: During use, the sealing between the connecting pipe and the conduit is not strong enough, and leakage may occur when hydraulic oil enters. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent hydraulic control device for crane luffing, which solves the problem that existing intelligent hydraulic control devices for crane luffing are difficult to improve sealing.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a crane luffing intelligent hydraulic control device, including a housing;

[0006] An inlet is installed at the top of the box, and a cover is installed at the top of the inlet. A water pump is installed on one side of the box, and a conduit is installed on one side of the water pump.

[0007] A sealing structure is installed on one side of the conduit. The sealing structure includes a second flange on one side of the conduit and a first flange on one side of the second flange. A connecting plate is installed on the outer side of both the first flange and the second flange.

[0008] A connecting pipe is installed on one side of the sealing structure, a hydraulic cylinder is installed on one side of the connecting pipe, and a hydraulic rod is installed at the bottom end of the hydraulic cylinder.

[0009] When in use, the top water pump generates suction to send hydraulic oil from inside the housing into the hydraulic cylinder through a conduit. The bottom water pump draws the hydraulic oil from inside the hydraulic cylinder back into the housing. This allows adjustment of the hydraulic oil capacity inside the hydraulic cylinder and thus of the hydraulic system.

[0010] Furthermore, a slot is provided at the top of the inlet, and a locking block is provided at the bottom of the cover. The inlet and the cover form a locking structure, which facilitates disassembly.

[0011] Furthermore, an anti-backflow structure is installed on one side of the water pump. The anti-backflow structure includes a one-way valve installed on one side of the water pump. A ring is installed on one side of the inside of the one-way valve. An mounting plate is installed on one side of the inside of the one-way valve. A spring is installed on one side of the mounting plate. A sealing plate is installed on one side of the spring. The anti-backflow structure can prevent hydraulic oil from flowing back.

[0012] Furthermore, the springs are arranged in a ring, and the springs and the sealing plate form an elastic connection, and the springs are elastic.

[0013] Furthermore, a valve structure is installed on the outside of the conduit. The valve structure includes a valve body installed on the outside of the conduit, a rotating shaft installed inside the valve body, and a handle installed at the top of the rotating shaft. The valve structure can control the opening and closing of the conduit.

[0014] Furthermore, valve plates are installed on both sides of the rotating shaft, and the valve plates are symmetrically distributed about the central axis of the rotating shaft. The valve plates can control the sealing of the valve body.

[0015] Furthermore, a fixing screw is installed on the outer side of the connecting plate, and a nut is installed on one side of the fixing screw. A sealing groove is provided on one side of the second flange, and a sealing block is installed on one side of the first flange. A sealing ring is provided on the outer side of the sealing block. The sealing structure can enhance the sealing between the connecting pipe and the conduit.

[0016] Furthermore, the nuts are arranged in a ring shape, and the nuts are arranged at equal intervals on one side of the first flange, and the nuts can be tightened onto the fixing screws.

[0017] Furthermore, the outer side wall of the fixing screw is uniformly provided with external threads, and the inner side wall of the nut is uniformly provided with internal threads that cooperate with the external threads. The fixing screw and the nut are threadedly connected, and the fixing screw can fix the flange.

[0018] Furthermore, the sealing ring and the sealing groove form an engaging structure, and the inner diameter of the sealing ring is smaller than the inner diameter of the sealing groove, making the engaging structure easy to disassemble.

[0019] The advantages of the intelligent hydraulic control device for crane luffing provided by this utility model are: during use, the sealing structure can be used to enhance the sealing between the connecting pipe and the guide pipe, the anti-backflow structure can be used to prevent the hydraulic oil from flowing back, and the valve structure can be used to control the opening and closing of the guide pipe.

[0020] By installing a first flange on one side of the connecting pipe, the connecting pipe and the conduit can be connected together through the cooperation of the first flange and the second flange. The fixing screw passes through the connecting plate and the nut can be tightened to fix the flange together. The sealing block on one side of the first flange can be inserted into the sealing groove of the second flange. A sealing ring is embedded on the outside of the sealing block. The sealing ring is made of rubber material. The sealing ring is squeezed by the sealing groove to block the sealing groove. The sealing ring can enhance the sealing between the flanges and prevent hydraulic oil leakage. This achieves the purpose of enhancing the sealing of the crane luffing intelligent hydraulic control device.

[0021] By installing a check valve on one side of the conduit, when hydraulic oil passes through the check valve, it can force open the sealing plate. Then, the hydraulic oil can pass through the ring, the sealing cloth, and the holes on the mounting plate through the check valve. After the hydraulic oil passes through the check valve, the elasticity of the spring will drive the sealing plate to move. The sealing plate can also block the ring. The backflowing hydraulic oil will be blocked by the sealing plate, preventing the hydraulic oil from flowing back. This achieves the purpose of the crane luffing intelligent hydraulic control device to prevent hydraulic oil backflow. Attached Figure Description
