Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
Referring to fig. 2, a steel wire rope sealing and guiding assembly comprises a clamping seat 4, a guiding sleeve 5, a clamping nut 3 and a arrowhead 7. One end of the guide sleeve 5 is mounted on the clamping seat 4, and the clamping seat 4 is used for clamping the steel wire rope 6 passing through the clamping seat and sending the steel wire rope into the guide sleeve 5. And the clamping seat 4 is provided with a clamping nut 3 for sealing the end part of the steel wire rope on the clamping seat 4. And a arrowhead 7 is arranged at the other end of the guide sleeve 5 and used for sealing the end part of the steel wire rope penetrating through the guide sleeve 5. That is to say, the two ends of the steel wire rope sequentially passing through the clamping seat 4 and the guide sleeve 5 are respectively sealed by the matching clamping structure between the clamping nut 3 and the clamping seat 4 and the matching clamping structure between the guide sleeve 5 and the arrowhead 7.
Specifically, one end of the guide sleeve 5 is wrapped outside the clamping seat 4 and is installed together with one end of the clamping seat 4. The clamping nut 3 is covered outside the clamping seat 4 and is installed with the other end of the clamping seat 4. The guide sleeve 5 is arranged at one end of the clamping seat 4 and is mutually abutted with one end of the clamping nut 3 arranged on the clamping seat, so that the clamping seat 4 is closed. Under the structure, the steel wire rope can be effectively sealed inside and is not easily interfered by the external environment.
In order to further improve the clamping tightness, the wire rope sealing guide assembly further comprises a clamping piece 11. The inner side of the clamping seat 4 is provided with a convex part 41 for clamping the steel wire rope, a gap is reserved between the inner side of the clamping seat 4 between the clamping nut 3 and the convex part 41 and the steel wire rope, and the gap is used for accommodating a clamping sheet 11 abutting against the clamping nut 3. The clamping piece 11 is arranged in the gap and can clamp the steel wire rope. In order to avoid that the clamping piece moves in the gap, which makes the clamping force uneven or ineffective, the clamping piece 11 not only abuts between the wire rope and the clamping shoe 4, but also abuts against the clamping nut 3. The contact surfaces of the clamping pieces and the clamping seats, which are mutually abutted, are inclined planes, so that the steel wire rope can be effectively sealed. In addition, in order to facilitate the smooth guiding of the steel wire rope in the guide sleeve 5, a gap is left between the inner side of the clamping seat 4 between the guide sleeve 5 and the convex part 41 and the steel wire rope.
The guide sleeve 5 can be a nylon guide sleeve. Both sides of the guide sleeve can be processed into flat surfaces.
The steel wire rope sealing guide assembly can be used for sealing steel wire ropes in other fields, is simple in structure and convenient to detach, and avoids the steel wire ropes from being polluted by the external environment.
The utility model discloses still provide a wire rope protection architecture that sea water environment used, this protection architecture include above-mentioned wire rope seal guide subassembly and protecting pipe 9. As shown in fig. 3, the steel cable sealing and guiding assembly is used for sealing a steel cable, and the sheath tube 9 is used for accommodating the steel cable sealing and guiding assembly. And a clamping nut 3 of the steel wire rope sealing and guiding component is fixed in a protecting sleeve 9 through a connecting sleeve 2.
The guide sleeve is provided with a flat groove. As shown in fig. 3, the sheathing tube 9 is provided with a stop pin opening 52. The shield sleeve 9 and the guide sleeve 5 are accommodated in the flat groove 51 through the stop pin 10 passing through the stop pin opening 52. The flat groove is a groove which is formed downwards from the surface of the guide sleeve relative to the end part of the guide sleeve for installing the arrowhead, and a step surface 511 is formed between the flat groove and the end part of the guide sleeve for installing the arrowhead. The flat groove 51 is matched with the stop pin 10 for use, so that the connecting rod 13 and the steel wire rope assembly can be still retained in the protective sleeve after being broken, and the risk of rolling into a filter screen is avoided. The stop pin opening 52 may facilitate the installation of the stop pin, which is an opening machined in the bottom of the sheath tube in vertical alignment with the stop pin. When the steel wire rope assembly falls, the position of the guide sleeve can be rotationally adjusted, and when the flat groove of the guide sleeve is touched by hand to be aligned with the lower opening of the protective sleeve, the stop pin can be screwed in to place, so that the underwater operation is very convenient. Preferably, the stop pin may be a threaded stop pin and the stop pin opening may also have threads that mate with the stop pin.
The uide bushing is the nylon uide bushing, can avoid wire rope and protective casing to take place to bump the mill. The two sides of the guide sleeve are processed into flat surfaces 52, so that silt can be prevented from accumulating.
The existing alarm device replaces the original steel wire rope with a plastic-lined steel wire rope, and two ends of the plastic-lined steel wire rope are exposed after being stripped of a plastic-lined layer. The steel wire rope is required to be installed in the protective sleeve when being installed underwater, wherein the exposed part of the steel wire rope is installed in the steel wire rope sealing component. In this case, there are two wire rope sealing and guiding assemblies, which are respectively used for sealing the parts of the two ends of the wire rope in the guiding sleeve, which are stripped from the plastic coating. In fig. 3, the left steel wire rope sealing and guiding assembly is an upper sealing and guiding assembly, and the right steel wire rope sealing and guiding assembly is a lower sealing and guiding assembly. The lower sealing assembly is connected with the hinged plate assembly through a connecting rod 13, and the upper sealing joint assembly is connected with the travel switch assembly through a pull rod with the same structure as the connecting rod.
During the operation of the unit, if the steel wire rope assembly needs to be replaced, all the components can be assembled on water and fall down through the protective sleeve, and only the stop pin, the connecting rod and the connecting sleeve need to be screwed in during underwater operation, so that the operation is convenient and rapid, and the underwater operation time is greatly shortened.
It will be understood by those skilled in the art that the embodiments of the present invention as described above and shown in the drawings are given by way of example only and are not limiting of the present invention. The purpose of the utility model is completely and effectively realized. The functional and structural principles of the present invention have been shown and described in the embodiments without departing from the principles, embodiments of the present invention may have any deformation or modification.
