Digital video monitoring cable for high-speed elevator and its installation and binding method

Abstract

The invention discloses a digital video monitoring cable for a high-speed elevator and an installing and binding method of the digital video monitoring cable. The digital video monitoring cable comprises a monitoring communication cable, an electrifying cable, four strands of anti-bending wire ropes and a butterfly outer sheath, wherein the butterfly outer sheath is in a butterfly outer sheath structure with two triangular grooves on the cross section; the butterfly outer sheath structure is formed by simultaneously removing an isosceles triangle inwards from each of two opposite sides of a rectangular frame; the monitoring communication cable and the electrifying cable are respectively arranged at the centre positions of two symmetrical triangles; the four strands of anti-bending wire ropes are symmetrically arranged at the positions at the inner sides of four vertex angles of the butterfly outer sheath structure respectively; the butterfly outer sheath and an elevator travelling cable are arranged in parallel and then are transversely bound by a transverse binding tape; and the transverse binding tape at the position of the gap between the butterfly outer sheath and the elevator travelling cable is vertically bound by a binding tape. Therefore, the anti-disturbance force of the cable in the high-speed up and down movement process is improved; damages caused by external force are avoided; and relatively long-term use of the monitoring cable is ensured.

Description

technical field

[0001] The invention relates to a monitoring cable, in particular to a monitoring cable in high-speed elevator digital video monitoring and an installation and binding method thereof. Background technique

[0002] With the emergence of more and more high-rise buildings, video surveillance equipment, such as surveillance cameras, advertising media video displays, etc., are installed in elevators; and these video equipment need video cables to provide safe and reliable transmission signals to ensure the safety of video equipment. work normally, but the cables installed in the existing high-speed elevators for digital video monitoring to transmit digital video signals are data communication cables. When the cable moves up and down with the elevator bridge car, the bending force generated by itself is dispersed and consumed by the outer sheath and the two strands of steel wire rope. The effect of video surveillance, and even the short-term failure of the video s...
