Abstract
The utility model relates to a positioning cable cleat for collecting bar, which consists of two cable cleat bodies(1), an insulating gasket(2), a positioning screw bolt(3), an elastic cylindrical pin(4) and a connecting screw bolt(5). A screw nut revolving-proof platform(8) is arranged on the cable cleat bodies(1) aside the two ends of the connecting screw bolt(5), a positioning screw nut(9) is arranged at the middle part of the positioning screw bolt(3), and the positioning screw nut(9) is connected with the positioning screw bolt(3) into a whole. The utility model has the advantages that the insulating gasket is tightly connected with the two cable cleat bodies, the positioning is accurate, the installation is simple and the structure is reasonable. The metal model copper alloy precision casting is adopted, and the positioning, mechanical performance and insulating ability are enhanced. The utility model is applicable for the installation on the clearance tunnel of the domestic subway tunnel sector and the electric railway bottom.
Description
The utility model relates to the bus duct steady ear of a kind of electrified railway and urban track traffic use.
The overhead rigid suspension that electrified railway and urban track traffic are used is general adopt have corresponding rigidity bus duct and contact wire composition, for vertical fixing hangs and the clamping bus duct, pantograph is evenly flowed, and wherein supporting key components and parts is the bus duct steady ear.The domestic Qun Dynasty-Yungang Grottoes ditch the funnel bin that removes is introduced 6 sections about tens meters overhead rigid suspensions, and the bus duct steady ear complex contour that is adopted, integral structure are two presser type clamping T-shape bus ducts, and material is a carbon structural steel.The overhead rigid suspension of France's pattern, the bus duct steady ear that is adopted is a casting copper alloy, integral structure is bolted two wire clip bodies that contain insulating gasket, vertical fixing and clamping " π " type bus duct, and its casting surface is more coarse, the physical dimension excessive clearance, complexity is installed, and insulating gasket is connected insecure with two wire clip bodies, when dowel bolt is connected with other parts, nut and dowel bolt rotate simultaneously, are not easy to site operation and install.
The purpose of this utility model is to design the bus duct steady ear of a kind of electrified railway and urban track traffic use.Insulating gasket and two wire clip bodies are connected firmly, and accurate positioning is installed simple, rational in infrastructure.Adopt the precision cast of metal paattern copper alloy, its location, mechanical property and insulating power all are improved.
Design plan of the present utility model: a kind of bus duct steady ear, by two wire clip bodies (1), insulating gasket (2), dowel bolt (3), elastic cylindrical pin (4) and tie bolt (5) constitute, two wire clip bodies (1) are gone up the horizontal direction symmetry and are shaped on screw (6), the vertical direction symmetry is shaped on semicircle orifice (7), tie bolt (5) passes screw (6) two wire clip bodies (1) is fixed together, insulating gasket (2) is embedded on two wire clip bodies (1) by elastic cylindrical pin (4), dowel bolt (3) passes semicircle orifice (7) and is sleeved on two wire clip bodies (1), the place, two ends that is positioned at tie bolt (5) on two wire clip bodies (1) is shaped on the anti-turntable (8) of nut, the middle part of dowel bolt (3) is shaped on setscrew nut (9), and setscrew nut (9) is an integral structure with dowel bolt (3).The quantity that insulating gasket (2) is embedded in the elastic cylindrical pin (4) on two wire clip bodies (1) is 4～8, and evenly arranges.
Advantage that the utility model compared with prior art has and effect:
1, setscrew nut on the dowel bolt and dowel bolt body are designed to one, and on two wire clip bodies, all be shaped on the anti-turntable of nut, site operation is installed very convenient, being particularly suitable for domestic subway tunnel section and electrified railway low headroom tunnel installs and uses, lack 6 kinds at same line section than the flexible suspension steady ear and connect parts, occupy little space, save civil engineering costs, the line service amount is less.
2, increase the quantity of insulating gasket and two wire clip body bonded assembly elastic cylindrical pins, make insulating gasket and two wire clip bodies be connected firmly accurate positioning.
3, adopt the casting of metal paattern copper alloy, smooth surface, compact conformation, size is accurate, can reduce stock allowance.
Fig. 1 is a structural front view of the present utility model,
Fig. 2 is a structure right elevation of the present utility model.
1,2 a kind of embodiment of the present utility model is described in conjunction with the accompanying drawings.
A kind of bus duct steady ear, by two wire clip bodies (1), insulating gasket (2), dowel bolt (3), elastic cylindrical pin (4) and tie bolt (5) constitute, two wire clip bodies (1) are gone up the horizontal direction symmetry and are shaped on screw (6), the vertical direction symmetry is shaped on semicircle orifice (7), tie bolt (5) passes screw (6) two wire clip bodies (1) is fixed together, insulating gasket (2) is embedded on two wire clip bodies (1) by elastic cylindrical pin (4), dowel bolt (3) passes semicircle orifice (7) and is sleeved on two wire clip bodies (1), the place, two ends that is positioned at tie bolt (5) on two wire clip bodies (1) is shaped on the anti-turntable (8) of nut, the middle part of dowel bolt (3) is shaped on setscrew nut (9), and setscrew nut (9) is an integral structure with dowel bolt (3).The quantity that insulating gasket (2) is embedded in the elastic cylindrical pin (4) on two wire clip bodies (1) is 4～8, and evenly arranges.
Two wire clip bodies of the present utility model adopt the precision cast of metal paattern copper alloy, all the other machine ups, and insulating gasket adopts rubber to suppress through mould, and dowel bolt and tie bolt, nut, packing ring all adopt the corrosion-resistant steel manufacturing.At the scene during construction and installation, tie bolt is unclamped with hexagonal key wrench, two wire clip bodies are embedded in the bus duct positioning table, check whether insulating gasket and bus duct positioning table are adjacent to, replace binding bolt with dial torque wrench then, make moment of torsion reach 25N.m, again dowel bolt is connected with the insulator at top.
The utility model is through the test section trail run that domesticizes at line of Guangzhou Underground, and respond well, the bus duct steady ear is connected firmly, do not have distortion, copper alloy wire clamp body rotproofness in tunnel is good, and pantograph-catenary current collection is stable, technology, safe and reliable has satisfied city rail traction power supply and has been flowed requirement.
