Abstract
The invention discloses a high-speed pantograph head with double contact strips. The high-speed pantograph head comprises an upper top pipe (1), sleeves (2), two pantograph horns (3) and two spring supports (4); two sets of spring pieces are symmetrically arranged at the two sides of each spring support (4), each set of spring pieces is composed of the upper spring piece (5) and the lower spring piece (6) in parallel, and the ends of the spring pieces in each set are connected with one contact strip support (7); every two contact strip supports (7) located at the same side of the upper top plate (1) are provided with one contact strip (8), and namely the two contact strips (8) are symmetrically arranged at the two sides of the upper top plate (1). Several sets of simple spring pieces installed symmetrically are used for replacing an original complex spring hanging system, the high-speed pantograph head has the advantages of being light and good in aerodynamics performance. The two contact strips are used, and lighter contact strips can be used, and the following performance of the pantograph can be greatly improved.
Description
Technical field
The present invention relates to a kind of head of high-speed pantograph, particularly relate to a kind of two slide plate head of high-speed pantograph.
Background technology
Pantograph is the equipment that contact system is powered to motor train unit or electric locomotive.Because motor train unit or electric locomotive are that on the go contacts with contact system, require very high to the dynamic characteristics of pantograph.Bow is the critical component of pantograph, and the requirement of pantograph to bow is, structure is simple, lightweight, volume is little, air dynamic behaviour is good.At present, there is a variety of high speed pantograph in the world, also have a variety of head of high-speed pantograph.But the general all complex structures of collector head spring suspension, volume is large, quality is heavy, aerodynamic performance also receives larger impact.Li Fengliang had once invented a kind of head of high-speed pantograph (patent No.: ZL201010610605.4, hereinafter referred to as document 1).He gets up skid plates support with four laminated springs, attempts to address this problem.But owing to laminated spring being placed in the side of pantograph push pipe in design.When pantograph is run with different directions, aerodynamic force may be lift, also may be down-force, and in fact can not meet the speed of a motor vehicle is that more than 100km/h is subject to stream needs, does not have value of service.
Summary of the invention
Technical matters to be solved by this invention is the two slide plate head of high-speed pantographs that oscillation frequency is high, followability is high, aerodynamic performance is good, practical.
In order to solve the problems of the technologies described above, provided by the invention pair of slide plate head of high-speed pantograph, comprise push pipe, sleeve pipe, two Gong Jiao and two spring bearings, two groups of spring leafs are provided with in the bilateral symmetry of each described spring bearing, often organize described spring leaf to be made up of parallel upper spring sheet and lower spring sheet, the end often organizing described spring leaf is connected with a sliding bearing, every two described sliding bearings being in the same side of described upper push pipe are provided with a slide plate, and the slide plate namely described in two is symmetricly set on the both sides of described upper push pipe.
Described lower spring sheet there is superimposed spring leaf near described spring bearing place in described sliding bearing place and described upper spring sheet, described superimposed spring leaf near described sliding bearing is fixedly connected with described sliding bearing, and the described superimposed spring near described spring bearing is fixedly connected with described spring bearing.
Described upper spring sheet is identical with the physical dimension of lower spring sheet, and elastic modulus E, bending resistant section coefficient W are identical with the mechanics parameter of Poisson's ratio μ.
Adopting two slide plate head of high-speed pantographs of technique scheme, is improve patent ZL201010610605.4.Laminated spring is placed in pantograph push pipe bilateral symmetry.Pantograph is run to that direction all has two groups of laminated springs to bear lift, and other two groups of laminated springs produce down-force, balance the air lifting force of bow, thus pantograph can be made to meet current collection at high speed needs.The present invention does like this spring system can be made to have nonlinear feature being also provided with superimposed spring near sliding bearing place and spring bearing place, is more conducive to the followability improving pantograph.
The present invention uses two slide plate.Two slide plates are placed on sliding bearing.Sliding bearing is all fixedly connected with laminated spring with spring bearing.Four groups of laminated spring placements symmetrical relative to push pipe.The mechanics parameter of four groups of laminated springs, elastic modulus E, bending resistant section coefficient W, and Poisson's ratio μ is identical, physical dimension is also identical.
Compared with prior art, the invention has the beneficial effects as follows:
One, overcome the design defect of document 1, this bow structure based on laminated spring is moved towards practical.
Two, the non-linear of the collector head spring based on laminated spring is achieved.Greatly can improve the followability of pantograph.
Three, bow adopts two slide plates, and every root slide plate only has the half of the slide plate weight of single slide plate pantograph.Oscillation frequency improves, and followability also improves greatly.
In sum, the present invention be that oscillation frequency improves, followability is high, aerodynamic performance good, practical and structure is simple, lightweight pair of slide plate head of high-speed pantograph.
Accompanying drawing explanation
Fig. 1 is three-dimensional structure entity design figure of the present invention.
Fig. 2 is punch forming figure of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
See Fig. 1 and Fig. 2, sleeve pipe 2 is inserted in push pipe 1, the two ends of sleeve pipe 2 are inserted at two bow angles 3 respectively, spring bearing 4 is fastened on the two ends of sleeve pipe 2 and bends angles 3 and sleeve pipe 2 consolidation by two, two groups of spring leafs are provided with in the bilateral symmetry of each spring bearing 4, often organize spring leaf to be made up of parallel upper spring sheet 5 and lower spring sheet 6, the end winding support often organizing spring leaf is connected with a sliding bearing 7, every two sliding bearings 7 being in the same side of push pipe 1 are fixed with a slide plate 8, and namely two slide plates 8 are symmetricly set on the both sides of push pipe 1.
Further, lower spring sheet 6 there is superimposed spring leaf near spring bearing 4 place in sliding bearing 7 place and upper spring sheet 5, superimposed spring leaf near sliding bearing 7 is fixedly connected with sliding bearing 7, and the superimposed spring near spring bearing 4 is fixedly connected with spring bearing 4.
Upper spring sheet 5 is identical with the physical dimension of lower spring sheet 6, and elastic modulus E, bending resistant section coefficient W are identical with the mechanics parameter of Poisson's ratio μ.
