Technical Field

[0001] The utility model relates to the technical field of hydraulic cylinder maintenance, in particular to a tool for quickly disassembling and assembling a displacement sensor in a hydraulic cylinder. Background Art

[0002] The hydraulic cylinder is an actuator in the hydraulic transmission system. It converts hydraulic energy into mechanical energy to enable the working mechanism to achieve linear or swinging motion. The hydraulic cylinder has the advantages of simple structure, reliable operation, smooth movement, and easy stepless speed regulation. Therefore, it is widely used in the hydraulic systems of various machines.

[0003] The displacement sensor used to measure the stroke of the hydraulic cylinder is usually installed on site by being embedded in the hydraulic cylinder. Due to the extremely limited installation space, when the sensor malfunctions and needs to be tested or replaced, the hydraulic cylinder can only be disassembled and taken out for testing or replacement during shutdown. The hidden dangers cannot be dealt with in time and the fault handling time is long. For this reason, the present application proposes a tool for quickly disassembling and assembling the displacement sensor in the hydraulic cylinder, which is suitable for the scenario of quickly disassembling and assembling the displacement sensor in the hydraulic cylinder.

[0005] The tool for quickly disassembling and assembling the displacement sensor in the hydraulic cylinder in the present scheme includes a connecting piece and a bayonet piece and a handle respectively connected to the two ends thereof, wherein the handle and the bayonet piece are parallel to each other and perpendicular to the connecting piece so that the handle and the bayonet piece can simultaneously rotate with the connecting piece as a rotation axis, and the bayonet piece is provided with a bayonet for matching the sensor mounting nut, wherein the connecting piece includes a coaxial connecting prism and a connecting sleeve, and the connecting prism is slidably matched with the connecting sleeve in the axial direction.

[0006] The technical solution further defined in the utility model is:

[0007] Furthermore, a prismatic groove having a cross section adapted to the connecting prism is provided in the connecting sleeve.

[0008] Furthermore, the connecting prism is connected to the bayonet piece, and the connecting sleeve is connected to the handle.

[0009] Furthermore, a sunken installation groove adapted to connect the end of the prism is provided on the bayonet piece, and the end of the prism is connected to the bayonet piece by welding.

[0010] Furthermore, a groove adapted to the end of the connecting sleeve is formed on the handle, and the end of the connecting sleeve is welded to the handle.

[0021] This embodiment provides a tool for quickly disassembling and assembling a displacement sensor in a hydraulic cylinder, such as Figure 1As shown, from top to bottom, it includes a handle 30, a connecting sleeve 22, a connecting prism 21 and a bayonet piece 10. The connecting sleeve 22 and the connecting prism 21 are combined into a connecting piece 20. Specifically, the handle 30 is cylindrical, 200 mm long, and has a cross-section of a circle with a diameter of 10 mm. A groove 31 with a depth of 5 mm is provided at the bottom thereof, so that the top of the connecting sleeve 22 can be inserted and welded and fixed. A prismatic groove 23 is provided at the bottom of the connecting sleeve 22. In this embodiment, it is specifically a quadrangular prism to accommodate the insertion of the connecting prism 21. The overall height of the connecting prism 21 is 605 mm. In some other embodiments, the prismatic groove 23 can also be other prismatic shapes, which only needs to be adapted to the connecting prism 21.

[0022] like Figure 2-4 As shown, a sunken mounting groove 11 is provided on the bayonet piece 10, so that the bottom of the connecting prism 21 can be inserted and welded and fixed. The bayonet 12 on the bayonet piece 10 has a width of 47 mm and is used to clamp the two opposite sides of the hexagonal nut. The thickness of the bayonet piece 10 itself is 6 mm, and the bayonet 12 is used to disassemble and assemble the bolt.

[0023] In this embodiment, see Figure 1 When the tool for quickly disassembling and assembling the displacement sensor in the hydraulic cylinder is assembled, the handle 30 and the bayonet member 10 are parallel to each other and perpendicular to the connecting member 20, so that the handle 30 and the bayonet member 10 can simultaneously rotate with the connecting member 20 as the rotation axis, and the coaxial connecting prism 21 and the connecting sleeve 22 on the connecting member 20 slide and cooperate in the axial direction. When the bayonet member 10 clamps the bolt member to be disassembled, the height of the handle 30 can be adjusted and the handle 30 can be controlled to rotate, which can be suitable for use environments with different depths.

[0024] This embodiment is mainly applicable to the scene of disassembling and assembling displacement sensors or other accessory bolts in a hydraulic cylinder, such as Figure 5 As shown, there is a sensor mounting nut 41 that needs to be disassembled in the hydraulic cylinder body 40, but since the hydraulic cylinder body 40 has a certain depth, ordinary wrenches and disassembly tools are inefficient to use. After using the tool, the tool is inserted downward into the hydraulic cylinder body 40, the bayonet 12 is aligned with the sensor mounting nut 41, the connecting sleeve 22 is controlled to rise and fall to adjust the height of the handle 30, and the handle 30 is manually controlled to rotate, so that the bayonet part 10 can be conveniently controlled to disassemble and assemble the sensor mounting nut 41. When the displacement sensor is abnormal, it can be quickly disassembled for detection and replacement without waiting for shutdown, resulting in the expansion of the fault scope and affecting the production rhythm due to untimely handling of hidden dangers. The daily maintenance work of workers on such sensors is simplified, the labor intensity is reduced, and the efficiency is improved.

[0025] It should be noted that in the present embodiment, the connection between the connecting member 20 and the handle 30 and the bayonet member 10 is all welded. In some other embodiments, they may also be bolted, bolt-fitted welded or other detachable connection methods.

[0026] In addition to the above embodiments, the present invention may also have other implementation modes; any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the protection scope required by the present invention.
