Embodiment
Fig. 1～7th, most preferred embodiment of the present invention, below in conjunction with accompanying drawing 1～7, the present invention will be further described.
As shown in Figure 1, electric bus charging wire protector, comprises the protection of welded joints assembly that charging wire 11 joints are protected and the cable protective sleeve 9 that charging wire 11 bodies are protected.Wherein, protection of welded joints assembly comprises and is arranged on the protection of welded joints cover of charging pile 10 outsides and is arranged on that charging pile 10 is inner overlaps supporting joint fixed head with protection of welded joints.
As shown in Figure 2, joint fixed head is rectangle, and its center has the through wires hole 1 supporting with charging wire 11 thicknesses, at four jiaos of places of joint fixed head, is respectively provided with a fixing hole 2.
As shown in Fig. 3～5, the protection of welded joints cover body 3 that protection of welded joints cover comprises protective jacket fixed head 5 and is arranged on protective jacket fixed head 5 middle parts, protection of welded joints cover body 3 is structure as a whole with protection of welded joints cover fixed head 5.Protection of welded joints cover fixed head 5 structures are identical with joint fixed plate structure, comprise the fixing hole 2 that is opened in the through wires hole 1 of the center and is opened in four jiaos of places, and joint joint fixed head matches with the position of fixing hole 2 with the through wires hole 1 on protection of welded joints cover fixed head 5.
Protection of welded joints cover body 3 be thick outer thin taper tubular in inferior thick, external diameter on internal diameter, and axial opening of from-inner-to-outer opening on protection of welded joints cover body 3, when actual installation, is somebody's turn to do that Open Side Down, can guarantee best fastening strength.Protection of welded joints cover body 3 is arranged on through wires hole 1 place at protection of welded joints cover fixed head 5 middle parts, and the opening in protection of welded joints cover body 3 overlaps with the through wires hole 1 at protection of welded joints cover fixed head 5 middle parts.The both sides of protection of welded joints cover body 3 axially opens are arranged side by side a plurality of buckles 6 that opening can be locked, and in the both sides of protection of welded joints cover body 3 axially open roots, be respectively arranged with can be by the fixed block 4 of protection of welded joints body 3 root openings lockings.At the middle part of both sides fixed block 4, respectively have a circular hole, between two fixed blocks 4, be bolted.At protection of welded joints cover body 3 and protection of welded joints, overlapping the root that fixed head 5 is connected is charging wire 11 position the most easy to crack, with boltsly can guarantee best constant intensity.
Outer surface axially spaced-apart at protection of welded joints cover body 3 has some grooves, in adjacent two grooves, is provided with reinforcement.When operating personnel drag charging wire 11, the bending that can facilitate protection of welded joints cover body 3 to realize to a certain extent, has extended useful life.
As shown in Figure 6, buckle 6 comprises that being fixed on protection of welded joints overlaps the card pin 7 of body 3 axially open one sides and be fixed on the draw-in groove 8 that protection of welded joints overlaps body 3 axially open opposite sides.Card pin 7 is arrow shaped, and draw-in groove 8 is rectangle frame, is each side provided with a Ka Tai in rectangle frame, and after card pin 7 stretches in draw-in groove 8, the rear end of sagittate card pin 7 is stuck in the Ka Tai place in draw-in groove 8, makes card pin 7 be difficult for deviating from.The mode coordinating with draw-in groove 8 by card pin 7 is locked the axially open of protection of welded joints body 3, easy to operate, has good locking effect simultaneously.
As shown in Figure 7, the thick tubular such as cable protective sleeve 9 is inside and outside footpath has axially open simultaneously on cable protective sleeve 9, in the both sides of axially open, be arranged side by side a plurality of buckles 6 simultaneously.Cable protective sleeve 9, for being enclosed within charging wire body, prevents that charging wire from rubbing on the ground and wearing and tearing.
Specific operation process is as follows:
As shown in Figure 1, first the joint fixed head shown in Fig. 2 is placed in charging pile, and makes charging wire 11 through the through wires hole 1 at its middle part.Then get a protection of welded joints cover and also charging wire 11 is passed to the through wires hole 1 at protective jacket fixed head 5 middle parts simultaneously.After the corresponding fixing hole 2 through four jiaos of protective jacket fixed head 5 and joint fixed heads of bolt, protection of welded joints cover is fixed on the housing of charging pile 10, realize pre-fixing of charging wire 11.
Then will between two fixed blocks 4 of protection of welded joints body 3 roots, be bolted, the root of protection of welded joints cover is fixed, then, by the some buckle clampings on protection of welded joints body 3, complete the fixing of charging wire 11 joints.
According to the physical length of charging wire 11 and cable protective sleeve 9, get one or more cable protective sleeves 9 and be sleeved on charging wire 11 body outsides, and by the buckle clamping on cable protective sleeve 9, realize the protection of 9 pairs of charging wire 11 bodies of cable protective sleeve.
In this electric bus charging wire protector, the protection of welded joints assembly that the joint of charging wire 11 is protected and the cable protective sleeve 9 that charging wire 11 bodies are protected all adopt rubber to make.Joint fixed head and protective jacket fixed head 5 can be set to other shapes, as circle.
The above, be only preferred embodiment of the present invention, is not the present invention to be done to the restriction of other form, and any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solution of the present invention content that do not depart from, any simple modification, equivalent variations and the remodeling above embodiment done according to technical spirit of the present invention, still belong to the protection range of technical solution of the present invention.
