Description
Technical Field
[0001] This utility model relates to a liquid-driven rapid separation device, belonging to the field of pump cover pressure testing and leak detection technology. Background Technology
[0002] After the pump cover pressure test is completed, a rubber hammer needs to be used to tap the edge of the test fixture to separate the pump cover from the test fixture by relying solely on inertia.
[0003] Utility model patent number 202421749280.1 discloses a rapid separation device for a testing fixture. It includes a fixed base that snaps into the top opening of a pressure testing fixture. Hook connectors for detachable connection to the pressure testing fixture are installed on both sides of the fixed base. A manual lifting drive for driving the pump cover relative to the pressure testing fixture is installed in the middle of the fixed base. The output end of the manual lifting drive is fixedly connected to a fixed plate to control the lifting of the fixed plate. The fixed plate is detachably connected to the pump cover by connecting screws.
[0004] Although the aforementioned patent allows for the quick removal of the pump cover from the pressurizing fixture using a manual lifting drive, the current technology is not comprehensive and has the following drawbacks: 1. Wear occurs between the cam eccentric handle and the fixed seat after repeated pressing, leading to reduced separation efficiency or inability to separate quickly; 2. The cam eccentric handle may bend due to insufficient rigidity; 3. Since the original device still requires manual pressing, it demands strength from the worker and is not suitable for operators with different physical abilities, resulting in a heavy workload for the worker.
[0005] To solve one of the above problems, there is an urgent need for a liquid-driven rapid separation device. Utility Model Content
[0006] Based on the shortcomings of the existing technology, the technical problem to be solved by this utility model is: how to combine the lifting cylinder to provide continuous pulling force so that the pump cover in the pressure fixture can be quickly separated from the pressure fixture, reducing the reliance on manual labor and making it suitable for operators with different physical abilities. To this end, a hydraulically driven rapid separation device is provided.
[0007] The liquid-driven rapid separation device of this utility model includes a fixed seat that is fastened to the top opening of the pressure fixture. Rotary hook connectors for detachable connection with the pressure fixture are installed on both sides of the fixed seat. A lifting drive component for driving the pump cover to move relative to the pressure fixture is installed in the middle of the fixed seat. The lifting drive component is a lifting cylinder installed on the fixed seat. A fixed plate is detachably installed on the pump cover. The piston rod A of the lifting cylinder passes through the fixed seat and is welded to the lifting rod. The lifting rod and the piston rod A of the fixed seat are coaxially arranged, and the bottom end of the lifting rod is detachably connected to the fixed plate.
[0008] After the pump cover has completed the pressure test, it needs to be separated from the pressure testing fixture. This application uses a rotary hook connector to achieve quick assembly and separation of the fixed seat and the pressure testing fixture. Alternatively, the lifting rod and the fixed plate can be assembled and separated using connecting bolt B, and the pump cover and the fixed plate can be assembled and separated using connecting bolt A. Through the synergistic effect of the above structures, and combined with the lifting cylinder to provide continuous pulling force, the pump cover in the pressure testing fixture can be quickly separated from the pressure testing fixture.
[0009] Hydraulic drive replaces manual operation, improving safety during separation and disassembly, and further freeing up workers' labor.
[0010] In any of the above embodiments, preferably, the lifting cylinder includes a cylinder body and a piston rod A. The front end of the cylinder body is fixed to a fixed seat by connecting screws. A circular hole for the piston rod A to pass through is opened at the center of the fixed seat. The tail end of the piston rod A is located inside the cylinder body, and a piston A that cooperates with the cylinder body is provided at the tail end of the cylinder body. The piston A divides the cylinder body into a rod chamber and a rodless chamber. A rear end cover is installed at the tail end of the cylinder body. An oil port A communicating with the rodless chamber is opened on the rear end cover. An oil port B communicating with the rod chamber is opened on the outer wall of the front end of the cylinder body. A front guide sleeve that cooperates with the piston rod A is provided on the inner wall of the front end of the cylinder body. A combined seal is installed on the front guide sleeve.
[0011] Hydraulic oil enters the rodless chamber through port A or the rod chamber through port B, pushing piston A to move and causing piston rod A to extend and retract, achieving bidirectional control. The front guide sleeve ensures motion stability, the combined seals prevent leakage, and the lifting cylinder continuously provides pulling force to separate the pump cover and the pressure fixture, enabling the pump cover to separate from the pressure fixture quickly.
[0012] In any of the above embodiments, preferably, the lifting cylinder includes a cylinder body and a piston rod A. The front end of the cylinder body is fixed to a fixed seat by a connecting screw. A circular hole for the piston rod A to pass through is opened at the center of the fixed seat. The tail end of the piston rod A is located inside the cylinder body, and a piston A that cooperates with the cylinder body is provided at the tail end of the cylinder body. The piston A divides the cylinder body into a rod chamber and a rodless chamber. A rear end cover is installed at the tail end of the cylinder body. A guide hole communicating with the rodless chamber is opened on the rear end cover. An oil port B communicating with the rod chamber is opened on the outer wall of the front end of the cylinder body. A front guide sleeve that cooperates with the piston rod A is provided on the inner wall of the front end of the cylinder body. A combined seal is installed on the front guide sleeve. A rear guide sleeve that cooperates with a sliding rod is installed in the guide hole. One end of the sliding rod is inserted into the rodless chamber and connected to the piston B. A return spring is provided between the rear end cover and the piston B. The return spring provides a thrust to push the piston B closer to the piston A.
[0013] Hydraulic drive stage: The oil pump is turned on, and high-pressure oil enters the rod chamber through oil port B, pushing piston A to move upward and driving piston rod A to retract.

[0014] Spring reset phase: The oil pump is turned off, and the rod chamber of the lifting cylinder is connected to the oil tank. After the lifting cylinder is depressurized, the reset spring pushes the piston B downward, the piston B pushes the piston rod downward, the oil in the rod chamber returns through the oil port B, and the piston rod extends out of the cylinder body.
[0015] The hydraulic stage utilizes high-pressure oil to directly perform work, resulting in high energy transfer efficiency and ensuring a stable and reliable separation process; the spring reset stage only requires the release of elastic potential energy, leading to low energy consumption. The rear guide sleeve also integrates a combined seal.

[0018] In any of the above embodiments, it is preferred that the rotary hook connector includes a pull rod body, the upper end of which is rotatably mounted on a fixed base via a bearing, and the other end of which is integrally provided with a hook head. By rotating the rotary hook connector, the hook head can be hooked onto the bottom of the pressing fixture or detached from the bottom of the pressing fixture.
[0019] The hook head can be switched relative to the pressing fixture by means of a pull rod that can be positioned relative to the fixed seat, thus enabling the two to be engaged or disengaged. In the engaged state, the fixed seat is restricted from being removed from the pressing fixture. In the disengaged state, the fixed seat can be removed from the pressing fixture. The structure is simple and reasonable, enabling quick connection between the movable connector and the pressing fixture.
[0020] In any of the above embodiments, it is preferred that the bottom end of the lifting rod is provided with a threaded hole, and the bolt body of the connecting bolt B passes through the fixing plate and connects with the threaded hole to fix the fixing plate to the bottom end of the lifting rod.
