In this embodiment, the sideslip preventing assembly 3 includes a rotating shaft 301, a forward rotation gear 302, a first gear 303, a belt 304, a second gear 305, and a reverse rotation gear 306, the inner wall of the side frame plate 13 is rotatably connected with four rotating shafts 301, each rotating shaft 301 rotatably penetrates four rotating holes 1302 formed in the side frame plate 13, each side frame plate 13 is fixedly connected with a side plate 1301, each rotating shaft 301 is respectively and fixedly penetrated through the forward rotation gear 302 and the reverse rotation gear 306, the forward rotation gears 302 and the reverse rotation gears 306 are alternately arranged, the belt 304 for driving is connected between the two forward rotation gears 302, the belt 304 for driving is connected between the two reverse rotation gears 306, the first gear 303 and the second gear 305 are fixedly connected to the end portions of the rotating shafts 301 on the adjacent reverse rotation gears 306 and the forward rotation gears 302, the first gear 303 and the second gear 305 are engaged with each other, the end portion of each rotating shaft 301 extending out of the side plate 1301 is fixedly connected with a roller 14, simultaneously after the installation, because of the outside moisture and the whole heavier production marginal cable of cable upwards squints the scheduling problem, can drive the rotation of cylinder 14, when arbitrary cylinder 14 rotated, through the drive of belt 304, make the intermeshing of first gear 303 and second gear 305, and connect the opposite problem of direction of rotation through adjacent meshing, make two cylinders 14 of 4 cylinder bells carry out the rotation of opposite direction, thereby when the cable takes place to squint, can make every two cylinders 14 do the power to opposite direction and press from both sides tightly through anti-skidding glueballs 15.

The cable mounting structure for rail transit has the working principle that: a round hole is formed in a subway, a round rod 6 extends into the round hole and is fixed on a mounting wall through a fixed bolt plate 2, the mounting number of cables and the transverse length of a plurality of cables are measured, then the round rod 6 is moved to change the length of a cable mounting groove 11, when the round rod 6 is moved, a square plate 406 arranged at the upper end of a connecting rod 801 at the lower end is driven to slide in a plurality of clamping plates 402, a torsion spring 410 is arranged to enable the square plate 406 to slide in a torsional angle when the square plate collides with the clamping plates 402, the next clamping plate 402 slides to reset through the torsion spring 410, an arc plate and an inclined surface are arranged to reduce the friction between the square plate 406 and the clamping plates 402, meanwhile, the round rod 6 has a touch feeling when being moved, the clamping plates 402 arranged at equal intervals can facilitate a user to move and adjust the cable mounting groove 11 accurately and conveniently, after adjustment is finished, the hand ring 8 is rotated and tensioned, so that a clamping rod 508 moves in a limiting groove 506 and a straight sliding groove 507 pushes the connecting rod 801 upwards, thereby promote the second circular arc portion 408 of square plate 406 upper end and paste closely to first circular arc portion 403, then at the card pole 508 that rotates connecting rod 801 and make its lower extreme carry out spacing connecting rod 801's slip, through the chucking of square plate 406 in first draw-in groove 401, thereby round bar 6's removal has been stabilized, make equipment can adjust the length of cable mounting groove 11 wantonly and carry out the chucking, conveniently adjust the length of cable mounting groove 11 simultaneously, make equipment simple, the stable characteristics after providing high-efficient installation cable and the installation.

Simultaneously after the installation, because of the outside moisture and the whole heavier production marginal cable of cable squint etc. that makes progress, can drive the rotation of cylinder 14, when arbitrary cylinder 14 rotated, through the drive of belt 304, make the intermeshing of first gear 303 and second gear 305, and connect the opposite problem of direction of rotation through adjacent meshing, two cylinders 14 that make 4 cylinder bells carry out the rotation of opposite direction, thereby when the cable takes place to squint, can make every two cylinders 14 do the power to opposite direction and press from both sides through anti-skidding glueballs 15, the effectual problem that prevents the cable skew, the use after having provided the installation cable is stable.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
