Abstract
Description
Technical Field
[0001] This utility model relates to a system for guiding retractable ropes, lines and cables, and more particularly to a cable guide. Background Technology
[0002] Cable guides, such as anchor chain guides, can be used to guide and restrict the lateral movement of ropes and / or cables. Specifically, the rope and / or cable can pass through an opening in the cable guide, and the lateral movement of the rope and / or cable can be restricted within said opening. Cable guides can be used in winches, cranes, boats, and other applications where the rope and / or cable undergo bidirectional movement. When the rope and / or cable is pulled through the cable guide, it can contact the surface of the opening. The surface of the cable guide opening can tend to wear due to prolonged contact with the rope and / or cable.
[0003] The existing cable guide includes a cable guide housing with a cable guide hole. The cable guide hole is a through hole with the front and rear ends turned outwards to form a front guide hole with a large flared hole facing forward and a rear guide hole with a large flared hole facing backwards, respectively. A cable guide hole liner made of wear-resistant material is provided in the cable guide hole. The cable guide hole liner includes a front liner and a rear liner. The front liner and the rear liner are respectively inserted into the flared holes at the front and rear ends of the cable guide hole in the cable guide housing. A gap is left between the rear end face of the front liner and the front end face of the rear liner. The rear end of the front liner and the front end of the rear liner are connected in the middle of the cable guide hole in the cable guide housing by several fastening components. The main drawback of existing cable guides is that the fastening components used for connection on the front and rear pads are generally bolts or bolt-nut assemblies. Whether bolts or bolt-nut assemblies, they are connected to the front and rear pads in a front-to-back direction. The front or rear pads need to be provided with countersunk holes for bolt hexagonal heads or nuts. These countersunk holes generally form notches on the surface of the flared hole inside the front or rear pad. When the cable guide is in use, these notches can easily damage the rope and / or cable passing through the holes of the cable guide, and also accelerate the wear of the rope and / or cable, significantly reducing the service life of the rope and / or cable. Utility Model Content
[0004] This utility model addresses the shortcomings of existing technologies by proposing a single-sided threaded and clamping plate connection structure for the cable guide hole liner, which can significantly reduce damage and wear of the rope and / or cable passing through the cable guide hole, thereby significantly extending the service life of the rope and / or cable.
[0005] The present invention achieves its technical objectives through the following technical solutions.
[0006] A single-sided threaded connection structure with a retaining plate is provided in a cable guide hole gasket. The cable guide hole gasket, located within a cable guide hole in a cable guide housing, includes a front gasket and a rear gasket. The cable guide hole in the cable guide housing is a through hole in the front-to-back direction, with the front and rear ends flared outwards to form flared bell-shaped holes. The front and rear gaskets are respectively inserted into the flared holes at the front and rear ends of the cable guide hole in the cable guide housing, with a gap between the rear end face of the front gasket and the front end face of the rear gasket. The improvement lies in that the rear end of the front gasket and the front end of the rear gasket are connected at the center of the cable guide hole in the cable guide housing by several single-sided threaded connection units. These single-sided threaded connection units are spaced apart around the rear end of the front gasket and the front end of the rear gasket. Each single-sided threaded connection unit includes a connecting... The system comprises a connecting bolt, a retaining plate, and a connecting nut. The connecting bolt includes a shoulder and a single-sided bolt. One end of the connecting bolt is a single-sided bolt, and the outer wall of the other end is recessed to form a journal. The shoulder is located between the single-sided bolt and the journal, and has a polygonal cross-section. The central axis of the connecting bolt is parallel to the central axis of the cable guide hole in the cable guide housing. Both ends of the connecting bolt are respectively inserted into the mounting holes of the connecting bolt through a clearance fit from the rear end face of the front pad and the front end face of the rear pad. The outer walls of the rear end of the front pad and the front end of the rear pad are respectively provided with a first radial retaining groove and a second retaining groove at the corresponding positions of the journal of the connecting bolt and the single-sided bolt. The retaining plate is radially inserted into the first retaining groove and engaged in the journal of the connecting bolt. The connecting nut is radially engaged in the second retaining groove. The single-sided bolt of the connecting bolt is threadedly connected to the connecting nut.
[0007] Furthermore, the connecting bolt connection portions on the rear end face of the front liner and the front end face of the rear liner are respectively provided with radial straight grooves with relatively open openings.
[0008] Furthermore, the cross-section of the shoulder of the connecting bolt is hexagonal.
[0009] Compared with the prior art, this utility model has the following advantages: 1. The rear end of the front pad and the front end of the rear pad are connected in the middle of the cable guide hole in the cable guide housing by several single-sided threaded connection units. On the one hand, no gaps are formed on the surface of the horn hole in the front pad or the rear pad, which can significantly reduce the damage and wear of the rope and / or cable passing through the cable guide hole, thereby significantly extending the service life of the rope and / or cable passing through. On the other hand, the clamping plate structure allows for quick adjustment.
[0010] 2. The connecting bolt connection parts on the rear end face of the front pad and the front end face of the rear pad are respectively provided with radial straight grooves with opposite openings. In this way, when using this utility model, a wrench can be inserted into the radial straight groove to adjust the double-headed bolt, increasing the adjustment space and improving the assembly efficiency.
