Embodiment 1

[0038] This embodiment provides a lubricating and maintaining device for stay cables, which includes a cylinder body 3 and a sealing cover assembly 4. Both ends of the cylinder body 3 in the axial direction and the sealing cover assembly 4 are equipped with Through holes, the shape of the cylinder body 3 can be square or circular and other cylindrical structures. The outer edge side wall of the sealing cover plate assembly 4 is in sliding contact with the inner wall of the cylinder body 3, preferably a dynamic sealing contact. 1. A chamber is formed between the side wall section of the cylinder body 3 and the sealing cover assembly 4 to accommodate the lubricating grease; The inner wall can be adapted. In order to realize the reciprocating dynamic sealing connection, a rubber sealing ring can be arranged on the outer edge side wall of the sealing cover assembly 4, so that the rubber sealing ring can be pressed against the outer edge side wall of the sealing cover assembly 4 an...

Embodiment 2

[0041] An improvement is made on the basis of Example 1, the cylinder 3 includes a cylinder wall and a cylinder assembly 5, and the cylinder 3 is designed to be a cylindrical structure; the cylinder assembly 5 includes a bottom plate 51 and a sealing plate 52, and the bottom plate 51 is detachably fixed At the bottom of the cylinder wall, the bottom plate 51 is a circular plate structure, and if it is fixed on the bottom of the cylinder wall by bolt connection, it realizes the opening and sealing of the bottom of the cylinder wall. The bottom plate 51 is provided with a through hole I511 and a slit I512 for passing the stay cable 1, and the slit I512 extends from the edge of the bottom plate 51 to the through hole I511 and communicates with the through hole I511; the sealing plate 52 is slidably arranged on the bottom plate 51 , used to cover the incision I512. If the sealing plate 52 adopts a fan-shaped plate structure, the inner arc section of the fan-shaped plate is close t...

Embodiment 3

[0046] Further improvement on the basis of Example 2, the top of the cylinder 3 is also provided with a cleaning part, the cleaning part and the smearing part move synchronously with the cylinder 3, and the cleaning part is used to clean the sundries on the stay cable, such as the oblique Aged, weathered grease and dust on the cables.

[0047] Optimized design, the smearing part adopts the sleeve bristle assembly II7, and the cleaning part adopts the sleeve bristle assembly I6. The sleeve bristle assembly II7 and the sleeve bristle assembly I6 have the same structure, and the mirror images are symmetrically arranged at both ends of the cylinder body 3 in the axial direction. The outer diameter of the sleeve bristles 10 is smaller than the outer diameter of the barrel 3, and the shape of the sleeve bristles 10 is circular.

[0048] Sleeve bristle assembly I6 all comprises sleeve bristle 10 and four pull rod members 11; Sleeve bristle 10 is used to be sleeved on the stay cable 1...

Abstract

The invention discloses a stay cable lubrication maintenance device. The stay cable lubrication maintenance device comprises a cylinder and a sealing cover plate assembly, through holes allowing a stay cable to penetrate through are formed in the two axial ends of the cylinder and the sealing cover plate assembly, the side wall of the outer edge of the sealing cover plate assembly is in sliding contact with the inner wall of the cylinder, and a cavity between the sealing cover plate assembly and the cylinder is used for containing lubricating grease; and the stay cable lubrication maintenancedevice further comprises a paratrooper rope II, one end of the paratrooper rope II is connected with the sealing cover plate assembly, and the other end of the paratrooper rope II penetrates out of the bottom of the cylinder and extends outwards. The paratrooper rope II is pulled to drive the sealing cover plate assembly to move in the axial direction in the cylinder, lubricating grease in the cavity is extruded, and the lubricating grease is extruded out through a gap between the inner wall of the through hole in the bottom of the cylinder and the outer wall of the stay cable; and the top ofthe cylinder is used for being connected with a traction component, and a smearing component is further arranged at the bottom of the cylinder and used for smearing extruded lubricating grease on thestay cable. Under the safe and controllable condition, the stay cable without an outer-layer sealing cylinder is rapidly and effectively maintained.

Description

technical field [0001] The invention relates to the field of cable-stayed cables of high iron towers, in particular to a cable-stayed cable lubricating and maintenance device, especially used for lubricating and maintaining cable-stayed cables of nuclear power plant iron towers. Background technique [0002] At present, cable-stayed cable technology is mainly used in the structural stability of buildings such as cable-stayed bridges and high-level iron towers. In the application of cable-stayed bridge construction, the cable-stay cables used for anchoring will be wrapped with a layer of PE pipe from bottom to top. In terms of construction, the anchored stay cables are only steel cables, and there is no sealing sleeve for oil injection on the outer layer, and there is no such maintenance equipment on the market, so there is a high risk in the maintenance of the tower stay cables. Construction difficulties and other issues. [0003] According to the regulations in the "Techn...
