Description
Technical field
The rigid suspended bus duct elasticity of the utility model steady ear, relate to a kind of being applied in the subway tunnel rigid contact net, dynamically be subjected to fluidity to reduce abrasion of contact wire, improve its service life and improve train speed per hour thereby utilize springing to improve bow net, and have the bus duct steady ear of monomer simplified structure.
Background technology
The prior art of steady ear, general employing is closed up spelling by two double wire clamps and is formed.China Patent No. is 01240444.6 to disclose a kind of bus duct steady ear, as Fig. 1, shown in Figure 2, this steady ear is by two wire clip bodies 1, insulating gasket 2, dowel bolt 3, elastic cylindrical pin 4 and tie bolt 5 constitute, the horizontal direction symmetry is shaped on screw 6 on two steady ear bodies 1, the vertical direction symmetry is equipped with 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 major defect of the said goods of prior art is: shortage can be improved the damping measure that bow net dynamically is subjected to the fluidity energy; Wire clamp is askew the sticking up of meeting under the horizontal loading effect, and bus duct forms and jeopardizes the curved disconnected risk of vertical hanging insulator easily in the easy jam of wire clamp content, influences reliability of operation; The applied metal casting production process, efficient is low, cost is high; Assembled structure, wire clamp need to close up finishing the assembling of self with bus duct, and need to install behind the bus duct could overall fixed on insulator, operational procedure inconvenience separately, the part construction can not be arranged in advance.
The utility model content
In view of this, the technical matters that the utility model solved:, reach the lifting of production efficiency and the optimization that cost descends by a kind of futuramic unitary construction is provided; The ad hoc metallic elastic damping arrangement of wire clamp dynamically is subjected to the fluidity energy, the inordinate wear of slowing down contact system, and the potentiality that improve train speed per hour with what improve bow net.
Take off purpose on reaching, the technical solution adopted in the utility model is: a kind of rigid suspended bus duct elasticity steady ear, comprise main body rack and axostylus axostyle, this main body rack is the integrative-structure that is formed by the high strength aluminum alloy extrusion process, be formed with the spring holding part in the middle of the main body rack, the both sides, lower end are provided with for slide block bonded assembly flange, be provided with two on the main body rack axis to perforation, main body rack is enclosed within on the axostylus axostyle perforation by two, spring housing is located at the spring holding part that is positioned at main body rack on the axostylus axostyle, the axostylus axostyle middle part is provided with convex shoulder, axostylus axostyle gives support by convex shoulder to spring and main body rack, the axostylus axostyle bottom is provided with shoulder, the operating range that is situated between and decides main body rack and spring by shoulder;
Described slide block is fixed on the main body rack by bolt, nut, safety washer and pressing plate, and this slide block and bus duct couple positioned opposite have U-lag.
Be provided with spring chair between described spring upper end and the main body rack, the spring lower end is positioned on the convex shoulder by packing ring;
Described spring is metal cylinder helix compression spring, disc spring film cluster spring or rubber mass spring;
Described this axostylus axostyle is provided with elastic cylindrical pin, and this main body rack is provided with the groove hole, and elastic cylindrical pin is arranged in the groove hole, by the rotation of this elastic cylindrical pin restriction axostylus axostyle;
The beneficial effects of the utility model are:
1, the main body rack applied metal is squeezed into the prepackage integral body that a single component and [slide block+pressing plate+bolt] are formed in the technical program, reaches optimization economically.
(A) production efficiency of metal extrusion process and cost all are better than casting processing.
(B) improve the efficient that the bus duct Assembly ﹠Disassembly is constructed:
(i) steady ear integral body can be pre-installed on the insulator, refills bus duct then.Two working procedures can separately carry out, and help the optimization of operating efficiency.
Only need unclamp a nut when (ii) bus duct being installed, [slide block+pressing plate+bolt] assembly of just detachable lower bracket one side, the combination of opposite side is stayed and is supplied bus duct as the hook point of adorning/unloading on the support.
(iii) bus duct in place after, one group of [slide block+pressing plate+bolt] entire combination that unloads when reinstall, only needs tighten up nut from a side.
2, improve the inordinate wear that dynamically is subjected to fluidity energy, contact system of bow net, and the potentiality that improve train speed per hour, be to realize that by spring members the loading of bus duct that support bears is born by spring, therefore, bus duct is actually with the elasticity suspended pattern and is installed on the spring.In train driving, when vibration made pantograph act on the acceleration/accel rising of bus duct, spring force discharged, and acceleration/accel is closelyed follow the come-up of bus duct along with pantograph and had loose bowels, may too high contact force be weakened between bow net, the fluidity that is subjected between bow net can be improved then.Because spring can influence contact force between bow net with its sensitivity and height effective means, vibration and impact can be maintained uniformly all the time change in the scope, the corresponding minimizing of the probability of off-line and flashing, the wearing and tearing of contact wire are minimized, life-span is promoted, and train can higher speed per hour travel.
3, the technical program is utilized the rotation with respect to support of hole groove restraining spring Xiao of support and screw rod, and steady ear is after loading onto bus duct and being fixed in insulator, and support just can be firm locked with being connected of insulator, can not break away from mutually, and serviceability is higher.
4, axostylus axostyle is provided with two at a distance of the suitable strong point at support; Axle, hole cooperate closely; Four from upper and lower, left and right orientation of the U-lag that slide block has are equipped with appropriate space and provide carrying, location and guide function for bus duct.Above measure is guaranteed can askewly not stick up under the effect of steady ear loading in the horizontal direction, spring is regulated efficient and is fully played, the expansion of bus duct and contraction, under circuit (track) condition of the standard bending spring and the gradient, all can be free flexibly, bus duct can not occur stuck in wire clamp and jeopardize the risk of insulator bending strength, and serviceability is improved.
5, can dress up a composite entity in advance by bolt, pressing plate and slide block, and the protruding rafter that is provided with of frame bottom, when nut and bolt were tightened, only need tighten up connection from nut one side and get final product, and bolt and slide block can not followed tightening up of nut and be rotated.Measure makes the more convenient operation of installation.
6, slide block institute tool electric conductivity, the piece electrical performance that must possess for bus duct and steady ear, for reliability and when having a power failure maintenance required validity ground connection and the safety of equipment when the charging operation provides assurance.
7, the lower end of described axostylus axostyle is shaped on shoulder, decides the operating range of spring to be situated between.
8, spring is made by metal cylinder helix compression spring, and long service life, the adjusting function of spring can satisfy different needs and make convenient, flexible preferred and adjustment.
