Abstract
The utility model relates to a sliding support of a horizontal tie rod cable, which comprises a base, a sliding plate and a sliding block, wherein the sliding plate is fixed on the base, the sliding block is in sliding fit with the sliding plate, an arc-shaped groove for supporting a horizontal tie rod cable body is arranged on the sliding block, and the sliding direction of the sliding block on the sliding plate is consistent with the length direction of the horizontal tie rod cable body. The arc-shaped groove is matched with the external shape of the horizontal tie bar cable body to form surface contact. The slider is the nylon slider, the slide is the polytetrafluoroethylene slide. The tie rod cable body is in surface contact with the sliding block, so that the sliding block can be prevented from directly extruding the outer PE of the tie rod cable, the friction force is improved, and the sliding tendency of the sliding block is increased. The sliding block and the sliding plate are arranged in a sliding mode, so that the deformation requirement of the tie rod cable body can be met, the deformed shearing force is offset through the sliding of the sliding block, and the extrusion of the support to the cable body is reduced.
Description
Technical Field
The utility model relates to a roller bracket of a horizontal tie rod cable.
Background
The horizontal tie rod cable is an important structural part of the bridge, the outer layer of the horizontal tie rod cable is a PE layer, the horizontal tie rod cable is structurally supported through a nylon roller wheel support, and the PE layer is directly contacted with a roller wheel. The contact between the tie rod cable body and the nylon roller is point contact, the nylon roller cannot rotate freely, the direct extrusion of the nylon roller and the outer PE layer of the cable body can cause the conditions of sinking, cracking and the like of the outer PE layer of the tie rod cable, meanwhile, the horizontal tie rod cable rotates in the operation of the bridge, and most of the found damages are near the contact point between the horizontal tie rod cable and the roller.
If the PE on the outer layer of the cable body is damaged during the service period of the horizontal tied rod cable, the common method is to continue the service after PE repairing treatment is carried out on the damaged part, and the condition that the repaired part is repeatedly damaged exists in the later period, so that the service life and the safety of the stay cable are seriously influenced.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem that the horizontal tie rod cable is easy to damage near the contact point of the nylon roller, the utility model improves the roller bracket which is directly contacted with the horizontal tie rod cable, and reduces the abrasion of the roller to the tie rod cable body.
The technical scheme adopted by the utility model for solving the problems is as follows: a sliding support of a horizontal tie rod cable comprises a base, a sliding plate and a sliding block, wherein the sliding plate is fixed on the base, the sliding block is in sliding fit with the sliding plate, an arc-shaped groove used for supporting a horizontal tie rod cable body is formed in the sliding block, and the sliding direction of the sliding block on the sliding plate is consistent with the length direction of the horizontal tie rod cable body.
Preferably, the arc-shaped groove is matched with the external shape of the horizontal tie rod cable body to form a stable surface support so as to avoid overlarge local support pressure.
Preferably, the sliding plate is provided with a sliding groove, and the sliding block is arranged in the sliding groove and can slide along the sliding groove. And the front end and the rear end of the sliding groove are closed to form front and rear limiting when the sliding block slides forwards and backwards in the sliding groove.
Furthermore, the slider is nylon slider, the slide is the polytetrafluoroethylene slide, ensures gliding smooth and easy.
Compared with the prior art, the utility model has the advantages that:
(1) the tie rod cable body is in surface contact with the sliding block, so that the sliding block can be prevented from directly extruding the outer PE of the tie rod cable, the friction force is improved, and the sliding tendency of the sliding block is increased.
(2) The sliding block and the sliding plate are arranged in a sliding mode, so that the deformation requirement of the tie rod cable body can be met, the deformed shearing force is offset through the sliding of the sliding block, and the extrusion of the support to the cable body is reduced.

FIG. 2 is a side view of a prior art roller carriage;
FIG. 3 is a front view of a sliding bracket according to an embodiment of the present invention;
FIG. 4 is a side view of a sliding support according to an embodiment of the present invention;
in the figure, a nylon slide block 1, a polytetrafluoroethylene slide plate 2, a base 3 and an arc-shaped groove 4 are arranged.
Detailed Description
The present invention will be described in further detail below with reference to the embodiments of the drawings, which are illustrative and intended to be illustrative of the present invention and are not to be construed as limiting the present invention.
Traditional tie rod cable body is with gyro wheel support, including gyro wheel and support, the cable body supports on the gyro wheel, and the gyro wheel is difficult to realize nimble roll, can't in time react to the deformation of cable body, and the gyro wheel is more serious to the wearing and tearing of cable body.
The embodiment discloses a sliding support as improving, comprises base 3, polytetrafluoroethylene slide 2 and nylon sliding block 1, and polytetrafluoroethylene slide 2 is fixed on base 3, and nylon sliding block 1 and polytetrafluoroethylene slide 2 sliding fit are provided with the arc wall 4 that is used for supporting horizontal tie rod cable body on the nylon sliding block 1, and the radian of arc wall 4 matches with the cable body appearance and makes cable body and arc wall 4 constitute the face contact.
The polytetrafluoroethylene sliding plate 2 is provided with a sliding chute, and the extending direction of the sliding chute is consistent with the length direction of the cable body so as to adapt to the deformation of the cable body in the length direction. The nylon sliding block 1 is arranged in the sliding groove and can slide along the sliding groove, the nylon sliding block 1 is pressed in the sliding groove by the cable body during operation to prevent the nylon sliding block from being separated, and the front end and the rear end of the sliding groove are sealed to form front and rear limit when the nylon sliding block 1 slides in the sliding groove.
The sliding support with the structure can be used for replacing the traditional roller support, and after the PE damage repair of the outer layer of the tie rod cable and the replacement of the roller support are completed, PVF belts are proposed to be wound on the tie rod cable body exposed outside, so that the harm of ultraviolet rays to the PE sheath of the tie rod cable is reduced, and the service life of the tie rod cable is prolonged.
Although preferred embodiments of the present invention have been described in detail hereinabove, it should be clearly understood that modifications and variations of the present invention are possible to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
