The ends of a left clamping plate and a right clamping plate can be slidingly arranged in the clamping plate sliding grooves. Clamping bolts pass through the left clamping plate and the right clamping plate and tightly fasten the left clamping plate and the right clamping plate on groove mouth folding edges of the wire groove body. Opposite clamping faces of the left clamping plate and the right clamping plate are provided with cable clamping grooves, and the cable clamping grooves are arc grooves. The glass fiber reinforced plastic fixing wire groove can clamp the cable without damaging the cable, and the installation is convenient. Besides, the glass fiber reinforced plastic fixing wire groove is light in weight, strong in carrying capacity, and is suitable for various using environments.
Description
Technical field
The utility model relates to a kind of railway electric wires such as electric railway, passenger and freight special line and urban track traffic that are used for and lays annex, relates in particular to be used for fixing the railway cable trunking of installing through bridge.
Background technology
In railway constructions such as electric railway, passenger and freight special line and urban track traffic; Always to lay power transmission cable line, communicaton and signal cable line; These cables are to place to be installed in the special-purpose railway bed cable trunking in the railway bed both sides; And when the bridge, then be to adopt pre-buried wire casing at bridge pier up and down and across the bridge place, the railway cable then fixedly is loaded in the pre-buried wire casing; General per 10 meters high piers need preset about 12 of such wire casings, and every kilometer overpass then need preset 380 gap bridge wire casings at least.
Present railway cable gap bridge wire casing mostly adopts pre-buried steel C type channel-section steel earlier, and then with ply-yarn drill or directly with screw bunch of cables is pressed abd fixed in the C type channel-section steel, there is obvious defects in this structure in using; At first adopt ply-yarn drill or bolt screw to compress cable; Cable to compress contact-making surface little, thrust is concentrated, fixing insecure, poor stability; Be easy to cause the damage of protective coverings of cable, influence the useful life of cable; Especially as far as the telecommunication cable of transmitting high-frequency signal, its thrust also is easy to cause the variation of each heart yearn physical structure in the cable, directly has influence on the transmission performance of signal cable.Moreover this wire casing pursues being fixed of root to cable often, and not only the thrust size is difficult to control, and the fitting operation trouble, and workload is big, is unfavorable for the unification and the raising of cable fixed installation quality.In addition since the railway cable can be layed in the various comparatively rugged environments, existing steel wire casing Heavy Weight, poor-performing such as cost is high, and is heat insulation, corrosion-resistant is unfavorable for the fixing and protection through cable.
The utility model content
Not enough to existing in prior technology, the utility model technical problem to be solved is, provide a kind of fixed, do not damage cable, and the fixing wire casing of the railway gap bridge cable of convenient installation and operation.
In order to solve the problems of the technologies described above, the railway gap bridge cable fiberglass of the utility model is wire casing fixedly, comprises the wire casing body, and the cross section of this wire casing body is C type cross section, and the two cell wall inboards relative at said wire casing body are provided with the clamping plate chute; The end of a left side clamping plate and right clamping plate places said clamping plate chute slidably, and fishbolt passes said left clamping plate and right clamping plate tightening on the notch flanging of wire casing body.
After adopting said structure, owing to be provided with the left clamping plate and the right clamping plate of the cable that is used to be fixedly clamped in the online cell body, through the clamping plate cable that is fixedly clamped; At first make the contact-making surface of clamping cables become big; Clamping pressure diminishes, and neither can damage protective coverings of cable, also can not destroy the arrangement architecture of cable core; And fixed, clamp good stability.Adopt the clamp region many cable handled easilies that can disposablely be fixedly clamped again simultaneously, significantly reduce the fixing labour intensity of cable.Again because the two ends of left clamping plate and right clamping plate are the clamping plate chutes that place the wire casing body slidably; And through the fishbolt tightening on the notch flanging of wire casing body; The flanging outside that needs only online cell body so just can make things convenient for the tightening cable, not only fastening convenient installation and operation, and can guarantee easily that the size equalization of cable clamping force is consistent; It is firm both to have guaranteed to clamp, and does not injure cable again.Also since the cable of this structure fixedly wire casing be convenient to adopt glass fibre reinforced plastic structure; And glass fibre reinforced plastic structure had both had good insulation performance performance and performance such as heat-resisting, corrosion-resistant; More can be adapted to various abominable environments for use; Have again that light weight, bearing capacity are strong, low cost of manufacture, processability be good, can easily make the chute structure, has more soft cable grip simultaneously.
The further execution mode of the utility model is provided with the cable clamping slot on the said left clamping plate clamping area relative with right clamping plate.Clamping slot on said left clamping plate and the right clamping plate clamping area is an arc groove.This structure has better cable surface contact stabilization, and is fixing more reliable, more helps protecting cable.
Description of drawings
Below in conjunction with accompanying drawing and embodiment to the utility model railway gap bridge cable fiberglass fixedly wire casing be described further.
Fig. 1 is the fixedly structural representation of a kind of embodiment of wire casing of the utility model railway gap bridge cable fiberglass.
Among the figure, 1-wire casing body, 2-left clamping plate, 3-right clamping plate, 4-fishbolt, 5-binding nut, 6-cable, 7-notch flanging, 8-clamping plate chute, 9-set bolt, 10-bridge concrete.
Embodiment
Fixedly in the wire casing, wire casing body 1 is fixedly installed on the bridge concrete 10 with set bolt 9 railway gap bridge cable fiberglass shown in Figure 1, and bridge concrete 10 is a railway bridge bridge pier or across bridge, set bolt 9 adopts common expansion bolt.Wire casing body 1 is processed by fiberglass, and its cross section is C type cross section, and width is 15cm, highly is 25cm, and length is 50cm, and the notch both sides of online cell body 1 are provided with notch flanging 7 symmetrically.Online cell body 1 two relative cell wall inboards are provided with the clamping plate chute 8 of indent, and two plate ends of left clamping plate 2 and right clamping plate 3 place its pairing clamping plate chute 8 slidably.Left clamping plate 2 and right clamping plate 3 relative clamping areas are provided with three pairs of cable clamping slots of mutual correspondence, and this cable clamping slot is an arc groove.In left clamping plate 2 and position, right clamping plate 3 both ends fishbolt 4 is housed, these two fishbolts 4 pass corresponding bolt hole on left clamping plate 2 and right clamping plate 3 and the notch flanging 7 thereof, and with binding nut 5 tightenings on the notch flanging 7 of wire casing body 1.
With set bolt 9 wire casing body 1 is fixed on the bridge concrete 10 earlier during installation; After more left clamping plate 2 being put into the clamping plate chute 8 of wire casing body 1 correspondence and are loaded onto fishbolt 4; Cable 6 is put the cable clamping slot corresponding to the left clamping plate 2 from the notch position of wire casing body 1; Then right clamping plate 3 are covered on cable 6 binding nut 5 from the notch flanging 7 position tightening fishbolts 4.Because the clamping plate two ends are arranged in clamping plate chute 8, the plate end of right clamping plate 3 is stuck on the right trough rim of clamping plate chute 8, and the slip away left trough rim of clamping plate groove 8 of the plate end of left clamping plate 2, make two clamping plate each other near and clamping cables 6.Cable clamping slot number on the clamping plate is then corresponding with the required cable radical that is fixedly clamped.
