Abstract
The utility model discloses a kind of cable length adaptive supporting frame, comprise the fixed head being fixedly connected with bridge, the portable plate of carrying cable, be arranged on the rolling element between described fixed head and described portable plate; Described portable plate is provided with arc sections in position corresponding to the telescopic section with described cable, and described portable plate is provided with backplate at two side positions of described cable.The utility model, due to the structural design of above-mentioned portable plate, has adapted to the variation of cable length in telescopic process, especially; by arc sections being set at portable plate corresponding site; reduce the telescopic section of cable and the friction of support, reduced cable friction power, be conducive to protect cable.
Description
Technical field
The utility model relates to power construction technical field, relates in particular to a kind of cable length adaptive supporting frame.
Background technology
Along with socioeconomic development, power consumption is increasing, and more and more thicker power cable often will be crossed over river by bridge structure.
Because the main material of cable is rubber and metal, the main material of bridge is concrete and reinforcing bar, therefore, and both performance differences of expanding with heat and contract with cold.Very long when bridge, or cable is very thick, and while running into the more extreme temperature difference, both rates of expanding with heat and contract with cold can differ greatly.So cable when (being generally bottom or the sidepiece that is suspended on bridge) lays on bridge, be reserved long telescopic section.
The telescopic section of cable generally with the corresponding setting in expansion joint of bridge, be semi-open several fonts.When the flexible difference of cable and bridge is obvious, cable can pull this telescopic section, to adapt to the length variations of bridge, avoids cable to be subject to too large tension force and is damaged.
The problem running into is at present, cable is when pulled, tractive effort is larger, the crust of cable (being generally quality of rubber materials) produces friction with the support (being generally metal material or concrete material) of placing cable, cause cable sheath repeatedly to wear and tear, affect the useful life of cable, when serious, also may cause cable breakage or electric leakage.
Therefore, those skilled in the art are devoted to solve the problems of the technologies described above.
Utility model content
Because the above-mentioned defect of prior art, the utility model proposes a kind of simple in structurely, can appropriate cable length extend the cable length adaptive supporting frame needing.
For achieving the above object, the utility model provides a kind of cable length adaptive supporting frame, comprises the fixed head being fixedly connected with bridge, the portable plate of carrying cable, is arranged on the rolling element between described fixed head and described portable plate; Described portable plate is provided with arc sections in position corresponding to the telescopic section with described cable, and described portable plate is provided with backplate at two side positions of described cable.
Preferably, described arc sections and described portable plate are split, by bolt or buckle, are connected and fixed.
The beneficial effects of the utility model:
The utility model, due to the structural design of above-mentioned portable plate, has adapted to the variation of cable length in telescopic process, especially; by arc sections being set at portable plate corresponding site; reduce the telescopic section of cable and the friction of support, reduced cable friction power, be conducive to protect cable.
Below with reference to accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is described further, to understand fully the purpose of this utility model, feature and effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment;
Fig. 2 is opposite side structural representation embodiment illustrated in fig. 1.
Embodiment
As shown in Figure 1 to Figure 2, a kind of cable length adaptive supporting frame of the present utility model, is applied in the supporting bracket 1 of bridge, comprises the fixed head 21 being fixedly connected with supporting bracket 1, the portable plate 23 of carrying cable.
Between portable plate 23 and fixed head 21, by some rolling elements 22 are set, realization can relative sliding displacement.
Portable plate 23, for direct carrying cable 5, on position corresponding to the telescopic section 51 with cable 5, is also provided with one section of arc sections 24, and especially, the radian of this arc sections 24 is close or identical with the radian of telescopic section 51.
Two side positions at portable plate 23 are provided with backplate 25, and backplate 25 is for stopping cable 5 landings.
Further, the inner side of backplate 25 is arc, to reduce the damage to cable 5.
Arc sections 25 can be integrative-structure with portable plate 23.
In other embodiments, arc sections 25 can be also split with portable plate 23, by bolt or buckle, is connected and fixed.
The utility model is due to the structural design of above-mentioned portable plate, when cable expansion section is stretched, because the force of sliding friction between cable and portable plate can be greater than the force of rolling friction between portable plate and fixed head, therefore, relative displacement does not now occur between cable and portable plate, but the slip on fixed head carrys out the length variations of appropriate cable by portable plate.
When the sliding distance between portable plate and fixed head can not appropriate cable collapsing length while changing, cable just can slide on portable plate, with the length variations of appropriate cable.But owing to being provided with arc sections, reduced the telescopic section of cable and the friction of support, reduced cable friction power, be conducive to protect cable.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without creative work.Therefore, all technical staff in the art comply with design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in the determined protection range by claims.
