Detailed Description
The technical solution in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, and the terms used herein are for the purpose of describing particular embodiments only and are not intended to be limiting of the invention, and terms such as "and/or" as used herein include any and all combinations of one or more of the associated listed items; furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.
Referring to fig. 1 to 5, the embodiment of the present invention discloses a novel cable bridge expansion joint, which includes two connecting devices 1, a cable guiding device 2 and an expansion sleeve 3;
the two connecting devices 1 are respectively and fixedly connected to two ends of the telescopic sleeve 3, and one sides of the two connecting devices 1 close to the telescopic sleeve 3 are respectively and fixedly connected with the cable guide device 2;
The connecting device 1 comprises a connecting plate 11;
a cable hole 12 is formed in the connecting plate 11, a guide arc piece 13 is fixedly connected to one side, close to the telescopic sleeve 3, of the outer surface of the connecting plate 11, a connector 14 is fixedly connected to one side, far away from the telescopic sleeve 3, of the outer surface of the connecting plate 11, and a mounting hole 15 is formed in the outer surface of the connector 14; the upper surface of the connecting plate 11 is connected with a pressing rod 16 in a threaded manner, and the pressing rod 16 extends to the inside of the cable hole 12 and is rotatably connected to the inside of the clamping piece 17.
The two fixing blocks 21 are respectively fixed on one sides of the two connecting plates 11 close to the telescopic sleeves 3.
To sum up, the utility model relates to a novel cable testing bridge expansion joint, the operation flow in the use is as follows:
a cable is inserted into the telescopic sleeve 3 through the cable hole 12 of one of the connecting devices 1, passes through the cable positioning ring 25 when passing through the telescopic sleeve 3, and then passes out through the cable hole 12 of the other connecting device 1;
then, the pressing rod 16 is rotated, the cable is pressed in the cable hole 12 through the clamping sheet 17, the position of the cable is fixed, and the cable in the cable bridge stringing tube is prevented from being influenced during stretching;
