Description
Technical field
The utility model relates to the technical field of Highspeed Catenary, especially a kind of city rail bus duct electrically connecting clamp.
Background technology
In recent years, along with socioeconomic fast development, urban track traffic is had higher requirement, in order to adapt to the development of city rail under the new situation, also to contact system bus duct electric connection line be clipped in technology, have higher requirement in appearance requirement aspect.
Bus duct electrically connecting clamp is arranged in tunnel, and air humidity is large, tunnel internal corrosion rifle etc., and just there is very large potential safety hazard in bus duct electrically connecting clamp, and the safety of power supply can not get strong assurance.
Summary of the invention
The technical problems to be solved in the utility model is: in order to solve the problem proposing in above-mentioned background technology, the utility model provides a kind of city rail bus duct electrically connecting clamp, and easy for installation, Supply Security is high.
The utility model solves the technical scheme that its technical matters adopts: a kind of city rail bus duct electrically connecting clamp, the fixture block that comprises fastening assembly and parallel distribution identical with two block specifications, on two fixture blocks, offer respectively for clamping the clamping notch of bus duct, the opening direction of two clamping notches distributes relatively, two fixture blocks are controlled clamp distance between the two by fastening assembly, on the upper surface of two fixture blocks, are provided with copper to aluminum adapter bar.
In order to guarantee the location of two fixture blocks, therefore the copper to aluminum adapter bar on every fixture block and fixture block upper surface offers a plurality of positioning through hole jointly.
In order to guarantee fastening to two fixture blocks, therefore fastening assembly comprises through two fixture blocks and two overbolts that be arranged in parallel and two nuts matching with two overbolts respectively.
The beneficial effects of the utility model are: city rail bus duct electrically connecting clamp of the present utility model, for electrification railway contact net, connect and transmission current, mainly by two fixture blocks, formed, make it can not affect installation because of the skew of pitch of holes in fastening process is installed, and then realizes the electric continued access between each anchor section of rigid suspended bus duct; Moreover because the upper surface of two fixture blocks is all attached with copper to aluminum adapter bar, make electrically connecting clamp reasonably meet safety, stability and the sight of power supply, and improved greatly power supplying efficiency, can be under electric power thus supplied, the situation of aluminum alloy corrosion in conduction is well solved.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1.
In figure: 1, fixture block, 2, clamping notch, 3, copper to aluminum adapter bar, 4, positioning through hole, 5, overbolt, 6, nut.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
City rail bus duct electrically connecting clamp as depicted in figs. 1 and 2, the fixture block 1 that comprises fastening assembly and parallel distribution identical with two block specifications, on two fixture blocks 1, offer respectively for clamping the clamping notch 2 of bus duct, the opening direction of two clamping notches 2 distributes relatively, two fixture blocks 1 are controlled clamp distance between the two by fastening assembly, on the upper surface of two fixture blocks 1, be provided with copper to aluminum adapter bar 3, copper to aluminum adapter bar 3 makes electrically connecting clamp reasonably meet safety, stability and the sight of power supply, and has improved greatly power supplying efficiency.
Wherein, the copper to aluminum adapter bar 3 on every fixture block 1 and fixture block 1 upper surface offers a plurality of positioning through hole 4 jointly, in each positioning through hole 4, fixing screw is installed, and guarantees the location of two fixture blocks 1.
Fastening assembly comprises through two fixture blocks 1 and two overbolts 5 that be arranged in parallel and two nuts 6 matching with two overbolts 5 respectively, guarantees fastening to two fixture blocks 1.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on specification sheets, must determine its technical scope according to claim scope.
