Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cable laying, and in particular relates to a cable guiding and fixing protective sleeve. Background Art
[0002] During the movement of the gantry crane, it usually needs to pass over its own power supply box, and in the process of passing over the gantry crane's own power supply box, the cable connected to the gantry crane often needs to turn 180 degrees.
[0003] Therefore, during the long-term reciprocating operation of the gantry crane, the rigidity of the cable at the turning fixed point will gradually decrease, and the external insulation layer of the cable will age faster, thereby increasing the mechanical loss of the cable joint and the cable itself. In the long run, the cable will have problems such as poor contact, copper core breakage, insulation layer damage at the turning fixed point, and even in severe cases, it will directly lead to cable leakage, short circuit and sparking, which will seriously endanger the safety of production operations.

One end of the connecting pin shaft alternately passes through the fixed sleeve and the movable sleeve and is then plugged with a pin to rotatably connect the support and the connecting plate together; at the same time, it can also ensure that the connecting plate and the bending sleeve can rotate 180 degrees through the cylindrical fixed sleeve and the movable sleeve.
[0010] Furthermore, the connecting pin is in an L-shape, and one end thereof can be used to penetrate the fixed sleeve and the movable sleeve, and the other end is used as a handle and an abutment portion.
