Description

Technical Field

[0001] This utility model belongs to the field of water lock equipment maintenance tools, specifically a tool for opening and closing the end cover of a lock hydraulic oil tank. Background Technology

[0002] The hydraulic system of a ship lock is a crucial component ensuring its normal operation. The hydraulic oil tank, as an important container for storing hydraulic oil, needs to be opened during lock maintenance for operations such as oil replenishment, filter replacement, and internal cleaning. Traditionally, opening and closing the hydraulic oil tank end caps lacks specialized tools; a hammer is used to loosen the end cap through impact, followed by disassembly with suitable tools. This method is problematic. Firstly, forcefully hammering the end cap can damage it, causing deformation and sealing surface damage, affecting the tank's sealing performance and leading to hydraulic oil leaks, posing a potential threat to the stable operation of the lock's hydraulic system. Secondly, the violent hammering can cause injury to personnel. Furthermore, manual operation is inefficient, wasting significant time on repetitive bolt tightening, extending the maintenance cycle of the lock equipment, and reducing overall operational efficiency. Therefore, there is an urgent need for a specialized tooling system capable of efficiently, safely, and accurately opening and closing the hydraulic oil tank end caps of ship locks.

[0038] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0039] Example 1:

[0040] See Figure 1-11 A hydraulic oil tank end cover opening and closing fixture for a ship lock includes a gripping base plate 4. Multiple sets of end cover gripping claws 1 arranged radially in a circular manner are slidably mounted on the upper surface of the gripping base plate 4. The end cover gripping claws 1 engage with a large gripping gear 5 installed at the top center of the gripping base plate 4, and the rotation of the large gripping gear 5 drives the extension and retraction of the end cover gripping claws 1. The large gripping gear 5 meshes with a locking mechanism 2 to lock the end cover gripping claws 1. A handle structure 3, which drives the entire gripping base plate 4 to rotate, is fixedly installed on the top of the gripping base plate 4 and directly above the large gripping gear 5. This opening and closing fixture can be effectively used for opening hydraulic oil tank end covers, thus replacing the traditional manual disassembly process, effectively improving disassembly efficiency and ensuring operational safety.

[0041] During the disassembly process, the gripping base plate 4 is positioned on top of the fuel tank end cover. Then, the gripping gear 5 is driven by the locking mechanism 2, which in turn drives the end cover gripping claw 1. The end cover gripping claw 1 reliably clamps the fuel tank end cover. After clamping, the locking mechanism 2 keeps it locked. Then, the manual operating handle structure 3 is used to rotate and open the fuel tank end cover.

[0042] Furthermore, the end cap gripper 1 includes a telescopic gripper slide rod 102 that slides in conjunction with the gripping base plate 4. A telescopic gripper shaft 101 is provided at the top of one end of the telescopic gripper slide rod 102, and an arc-shaped clamp 103 is provided at the bottom of the other end. The telescopic gripper shaft 101, the telescopic gripper slide rod 102, and the arc-shaped clamp 103 are welded together. The end cap gripper 1 described above is mainly used to subsequently grip the fuel tank end cap, facilitating subsequent rotation and opening.

[0043] Furthermore, a base shaft 401 is fixed to the top center of the gripping base plate 4, and a gripping gear 5 is positioned and mounted on the base shaft 401. Multiple sets of base slide rails 402 are machined on the top surface of the gripping base plate 4, and the base slide rails 402 and the telescopic gripper slide rod 102 form a sliding fit. The gripping base plate 4 is provided with a locking shaft positioning hole 403, and a positioning boss 404 is machined on the bottom surface of the gripping base plate 4. The gripping base plate 4 is mainly used for mounting and installing the components of the entire opening and closing fixture. The base slide rails 402 ensure that the end cap gripper 1 can slide and extend radially, thus facilitating the subsequent clamping of the fuel tank end cap.

[0044] Furthermore, the positioning boss 404 is used for positioning and engaging with the surface structure of the fuel tank end cover. This positioning engagement ensures that a force point is provided for the installation and removal of the end cover during subsequent disassembly, guaranteeing sufficient torque for disassembly.

[0045] Furthermore, the gripping gear 5 is machined with multiple sets of circumferentially distributed gripping guide rails 502. The telescopic gripper shaft 101 is fitted into the gripping guide rails 502 and forms a sliding fit. The center of the gripping gear 5 is machined with a gear positioning hole 501, which mates with the base shaft 401. The gripping gear 5 is mainly used to convert its circumferential motion into the radial extension and retraction of the end cover gripping claw 1, thereby facilitating the clamping of the fuel tank end cover by the end cover gripping claw 1. In specific operation, the rotation of the gripping gear 5 drives the end cover gripping claw 1 to slide along the base slide rail 402 by the gripping guide rails 502 on the gripping gear 5, thereby synchronously achieving extension and retraction.

[0046] Furthermore, the handle structure 3 includes an upper cover 301, on which a long handle 302 made of high-strength aluminum alloy is welded and fixed. The upper cover 301 has multiple evenly distributed sets of threaded holes 303, which are fixedly connected to the gripping base plate 4 by bolts. The upper cover 301 is provided with a locking through hole 304 for the locking mechanism 2 to pass through. Through the aforementioned handle structure 3, the end cap can be disassembled and installed with minimal effort using the lever principle.

[0047] Furthermore, the locking mechanism 2 includes a locking shaft 205, which has a threaded end and a non-threaded end. A locking pinion 204 is welded to the non-threaded end of the locking shaft 205, and the locking pinion 204 meshes with the gripping gear 5. The threaded end of the locking shaft 205 extends to the upper cover 301 through a locking through-hole 304. A locking nut 203 is fitted to the threaded end of the locking shaft 205. A locking knob 202 is located on the end cap of the threaded end of the locking shaft 205, and a fixing bolt 201 is provided above the locking knob 202. The locking mechanism 2 can be used to drive the gripping gear 5 to rotate, and also to lock the position of the gripping gear 5 after clamping, thereby achieving the clamping state of the end cover gripping claw 1.

[0048] The locking nut 203 on the threaded end of the locking shaft 205 is rotated and locked, and the locking mechanism 2 is locked by friction with the upper cover 301, ensuring that the gripping gear 5 does not move after being locked.

[0049] Furthermore, the number of gripping guide rails 502, base plate slide rails 402, and end cap gripping claws 1 are the same, and there are at least two sets. This matching of numbers ensures reliable gripping of the fuel tank end cap during disassembly.

[0050] Furthermore, the number of gripping guide rails 502, base plate slide rails 402, and end cap gripping claws 1 is 5 sets.

[0051] The specific working process and principle of the device of this utility model are as follows:

[0052] When it is necessary to remove the fuel tank end cover, combine the positioning boss 404 of this utility model with the fuel tank end cover, rotate the locking knob 202 counterclockwise and use your hand to push the arc chuck 103 to clamp the circumference of the end cover. At this time, rotate the locking nut 203 to lock the locking mechanism 2, and use the long handle 3 to rotate clockwise to remove the fuel tank end cover.

[0053] When it is necessary to install the end cover, combine the positioning boss 404 of this utility model with the oil tank end cover, rotate the locking knob 202 counterclockwise and the arc chuck 103 cannot be pushed by hand to clamp the circumference of the end cover. At this time, rotate the locking nut 203 to lock the locking mechanism 2, and use the long handle 3 to rotate counterclockwise to install the oil tank end cover.
