Technical Field

[0001] This utility model relates to the field of hydraulic actuator technology, specifically a hydraulic cylinder sleeve connector. Background Technology

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or oscillating motion). It has a simple structure and reliable operation. When used to achieve reciprocating motion, it eliminates the need for a speed reduction device and has no transmission backlash, resulting in smooth movement. Therefore, it is widely used in the hydraulic systems of various machines. During its use, it needs to be used in conjunction with a connector.

[0003] However, existing connectors still have the following technical problems when in use:

[0004] Existing connectors have poor locking performance and cannot quickly lock and unlock, resulting in low security during use.

[0005] Therefore, a hydraulic cylinder sleeve connector is proposed to solve the above-mentioned problems. Utility Model Content

The lower ends of the two pawls on the side closest to each other are engaged with the side wall of the lower connecting member. Injection holes are opened on the left and right sides of the hydraulic cylinder sleeve. The lower ends of the two injection holes communicate with the locking hydraulic chambers.

[0023] Example:

[0024] Please see Figure 1-5 This utility model provides a technical solution:

[0025] A hydraulic cylinder sleeve connector includes a hydraulic cylinder sleeve body 9, a pipe connector 2 fixed to the upper end of the hydraulic cylinder sleeve body 9, an upper connector 1 fixed inside the pipe connector 2, a sealing ring 11 fixed to the lower end of the upper connector 1, a centering cone 13 fixed to the lower side of the hydraulic cylinder sleeve body 9, symmetrical locking hydraulic chambers opened at the lower end of the interior of the hydraulic cylinder sleeve body 9, a hydraulic cylinder cover 7 fixed to the upper end of the symmetrical locking hydraulic chambers, and limit grooves opened on the left and right sides of the upper connector 1, with each limit groove having a... There is a chuck 4, which can be locked inside the limiting groove. When the chuck 4 is squeezed by the driving ring plate, the chuck 4 can rotate around the part located inside the limiting groove as a fulcrum, thereby locking the lower end of the chuck 4 onto the lower connector 12. The upper end of the chuck 4 contacts the inner wall of the limiting groove. The lower end of the pipe connector 2 is fixed with symmetrical shims 3. The opposite sides of the two chucks 4 are in contact with the lower side of the shims 3. Support blocks are provided on the sidewalls of the chuck 4. When the driving ring plate 5 moves upward, the driving ring plate... The upper side of 5 will press against the support block on the side wall of the chuck 4. The chuck 4 will rotate counterclockwise again with the part located inside the limiting groove as the fulcrum, thereby separating the lower left end of the chuck 4 from the lower connecting piece 12. Hydraulic cylinder pistons 8 are slidably installed inside both locking hydraulic chambers. Piston connecting rods 6 are fixed to the upper side of both hydraulic cylinder pistons 8. Drive ring plates 5 are fixed to the upper ends of the rod walls of both piston connecting rods 6. The side walls of the drive ring plates 5 and the opposite sides of the two chucks 4 are all inclined surfaces. When the drive ring plates 5 move downwards, they can... The jaw 4 is squeezed by the mutual movement between the two inclined surfaces. The inclined surface of the drive ring plate 5 contacts the inclined surface of the jaw 4. The lower connecting piece 12 is arranged longitudinally inside the centering cone 13. The upper side of the lower connecting piece 12 contacts the lower side of the sealing ring 11. The lower ends of the two jaws 4 on the side closest to each other are engaged with the side wall of the lower connecting piece 12. The left and right sides of the hydraulic cylinder liner 9 are provided with injection holes. The lower ends of the two injection holes are connected to the locking hydraulic cavity. The upper ends of the two injection holes are provided with liquid-passing screws 10.

[0026] The pipe connector 2 is fixedly connected to the upper side of the hydraulic cylinder liner 9 by the evenly arranged first connecting bolts.

[0027] The upper connector 1 is fixedly connected to the pipe connector 2 by the second connecting bolt.

[0028] The hydraulic cylinder head 7 is fixedly connected to the inner wall of the hydraulic cylinder sleeve body 9 by the third connecting bolt.

[0029] The lower ends of the two claws 4 that are close to each other are provided with anti-slip texture, which increases the stability of clamping when the claws 4 come into contact with the lower connector 12.

[0030] The fluid-passing screw 10 has a fluid-passing cavity inside, and the fluid-passing screw is threadedly connected to the hydraulic cylinder liner 9 and the pipe connector 2.

[0031] Working principle:

[0032] Hydraulic jaw flange connector locking process: After the lower connector 12 enters the connector through the centering cone 13, the hydraulic control system opens the locking hydraulic valve. Hydraulic oil enters the locking hydraulic chamber through the fluid screw 10, pushing the hydraulic cylinder piston 8 downward and causing the piston connecting rod 6 and the drive ring plate 5 to move downward. When the drive ring plate 5 moves downward to the design limit position, it will compress the jaw 4 and begin to rotate with the upper end as the fulcrum, thereby locking the upper connector 1 and the lower connector 12. During the connection process between the upper connector 1 and the lower connector 12 through the jaw 4, a compressive force will be generated on the sealing ring 11, which can form a good metal seal at the connection when the connection is completed.

[0033] Unlocking process of hydraulic jaw flange connector: When unlocking the connector is required, the unlocking hydraulic valve can be opened through the hydraulic control system. Hydraulic oil enters the unlocking oil tank through the fluid screw 10, pushing the hydraulic cylinder piston 8 upward, and driving the piston connecting rod 6 and the drive ring plate 5 upward. As the drive ring plate 5 moves upward, it releases the radial force on the jaw 4. When it reaches a certain position, the drive ring plate 5 pushes the jaw 4 open. At this time, the jaw 4 is unlocked from the lower connecting piece 12. The upper connecting piece 1 then drives the entire connector upward to retract, completing the unlocking process.
