Description

Technical Field

[0001] The utility model relates to the technical field of cable fixing, in particular to a movable common cable tightening sleeve connector. Background Art

[0002] Usually, it is a rope-like cable made of several or several groups of wires (at least two in each group), each group of wires is insulated from each other and often twisted around a center, and the entire outside is covered with a highly insulating covering. The cable has the characteristics of internal power supply and external insulation.

[0003] During the laying process of the cable, whether it is laying on a high tower or laying in a shaft, one end of the cable needs to be lifted upward. However, the outer wall of the cable includes a smooth insulating sheath, which is easy to fall off during the lifting process. In addition, the inner wall of the cable contains metal wires. The cable is heavy and difficult to twist. It is difficult to fix one end of the cable, and it is not convenient to lift the cable upward. Therefore, we propose a movable ordinary cable tightening sleeve connector. Utility Model Content

[0004] The utility model aims to provide a movable common cable fastening sleeve connector to solve the above-mentioned technical deficiencies.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a movable ordinary cable tightening sleeve connector, comprising a first locking sleeve and a second locking sleeve, the second locking sleeve is arranged on the top of the first locking sleeve, and the outer walls of both sides of the first locking sleeve and the second locking sleeve are fixedly provided with fixing plates, the outer walls of the fixing plates are opened with fixing holes distributed at equal distances, and the outer wall of the fixing plate is movably connected with a hinge rod through the fixing hole, and the outer walls of one end of the hinge rod provided on the first locking sleeve and the second locking sleeve are movably connected using a rotating shaft through the opening, and an extrusion plate is fixedly provided on the outer wall of one side corresponding to the hinge rod, and a semi-arc extrusion block is fixedly provided on the outer wall of one end of the extrusion plate, and a lifting plate is provided on the top of the second locking sleeve, and positioning holes are opened on the outer walls of both ends of the lifting plate, and steel wire ropes are bolted to the two ends of the lifting plate through the positioning holes, and the bottom ends of the two steel wire ropes are fixedly connected to the inner walls of the fixing holes opened on the fixing plate on the second locking sleeve.

[0006] Preferably, a rubber pad is fixedly provided on the arc-shaped inner wall of the semi-arc extrusion block, which helps to increase the friction between the semi-arc extrusion block and the outer wall of the cable, while preventing the semi-arc extrusion block from damaging the external insulating rubber of the cable.

[0007] Preferably, a vertically upward metal rod is fixedly provided at the top center position of the lifting plate, and a lifting ring is fixedly provided at one end of the top of the metal rod, which is connected to the steel cable of the lifting equipment through the lifting ring to facilitate the utility model to be lifted upward.

[0008] Preferably, a threaded hole is formed on one outer wall of the first locking sleeve and the second locking sleeve, and a fastening bolt is screwed on the inner wall of the threaded hole. By tightening the fastening bolt, the cable inserted into the inner wall of the first locking sleeve and the second locking sleeve can be initially fixed.

[0009] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0010] One end of the cable passes through the inner walls of the first locking sleeve and the second locking sleeve in turn, and the fastening bolt is tightened. The lifting plate is driven upward by the lifting equipment, and the lifting plate drives the second locking sleeve upward through the wire rope. The second locking sleeve is first subjected to force, and the cable slides on the inner wall of the second locking sleeve. The hinged rods hinged to each other begin to straighten, and the semi-arc extrusion block fixedly arranged on the inner wall of the hinged rod through the extrusion plate clamps the cable. As the height of the cable lifting increases, the semi-arc extrusion block will clamp the outer wall of the cable tighter, which can prevent the cable from falling off during the lifting process, and facilitate lifting one end of the cable to a high place.

The rubber pad 9 is helpful to improve the friction of the semi-arc extrusion block 8 on the outer wall of the cable, and at the same time prevents the semi-arc extrusion block 8 from damaging the external insulating rubber of the cable. A threaded hole 10 is opened on the outer wall of one side of the first locking sleeve 1 and the second locking sleeve 2. A fastening bolt 11 is screwed on the inner wall of the threaded hole 10. By tightening the fastening bolt 11, the cable inserted into the inner wall of the first locking sleeve 1 and the second locking sleeve 2 can be preliminarily fixed.

[0022] Working principle of this utility model:

[0023] Refer to the instruction manual Figure 1-3When the utility model is used, firstly, the lifting ring 15 provided on the top of the lifting plate 3 is connected to the lifting device through the steel cable, and then the cable to be lifted is passed through the inner wall of the first locking sleeve 1, and then the cable is passed through the inner wall of the second locking sleeve 2, and the positions of the first locking sleeve 1 and the second locking sleeve 2 on the cable are adjusted so that the outer wall of the semi-arc extrusion block 8 contacts the outer wall of the cable, the hinged rods 6 hinged to each other are bent, and the fastening bolts 11 are tightened, and the lifting plate 3 is driven to move upward by the lifting device, and the lifting plate 3 drives the second locking sleeve 2 to move upward through the steel wire rope 14, and the second locking sleeve 2 is first subjected to force, and the second locking sleeve 2 drives the first locking sleeve 1 to lift the cable upward through the hinged rod 6. The cable is lifted upward through the second locking sleeve 2. The cable first slides on the inner wall of the second locking sleeve 2, and the hinged hinged rods 6 begin to straighten. The semi-arc extrusion block 8 fixedly provided on the inner wall of the hinged rod 6 through the extrusion plate 7 clamps the cable. As the height of the cable lifting increases, the sliding distance of the second locking sleeve 2 on the outer wall of the cable increases, and the semi-arc extrusion block 8 will clamp the outer wall of the cable more tightly, which can prevent the cable from falling off during the lifting process, and facilitate lifting one end of the cable to a high place.
