Description
Technical field
The present invention relates to track traffic track switch design technical field, especially, relate to the connection between a kind of medium-and low-speed maglev turnout junction girder
Device.
Background technology
Medium-and low-speed maglev track switch typically uses sectional type structure, is attached by attachment means between beam between turnout junction girder.Track switch is turning
The relatively rotating of two turnout junction girder when changing, by attachment means transmitting forces, and carries out spacing.In order to enable two turnout junction girder phases
To rotation, between the beam that existing medium-and low-speed maglev track switch is used, attachment means have employed the gun iron link seat in gap.But due to upper
Having gap between lower connecting base, turnout junction girder can not control in the movement of vertical direction so that causes relatively when magnetic-levitation train is by track switch
Big vibration, affects ride comfort, and can produce the environmental problems such as bigger noise.
Chinese patent 201120311257.0 discloses a kind of medium-and low-speed maglev track switch fine strain of millet middle hinge shaft device, its upper bearing plate with
Being provided with pivot shaft device between lower bearing plate, this vertical articulated structure only has spinfunction, is not intended on track switch fine strain of millet vertical direction
Freely up and down spend, then can not limit upper and lower vibration.
Summary of the invention
Present invention aim at providing the attachment means between a kind of medium-and low-speed maglev turnout junction girder, to solve turnout junction girder at vertical direction
The technical problem that degree of freedom is excessive.
For achieving the above object, the invention provides the attachment means between a kind of medium-and low-speed maglev turnout junction girder, including with first
Upper connecting base that Cha Liang connects and the lower connecting base that is connected with the second turnout junction girder, described lower connecting base is provided with and raises up
Two columns, are provided with slide block between described column, the self-lubricating brass sheet that described slide block is pressed on lower connecting base by pressing plate
Upper surface, and slide block is articulated with on upper connecting base by running through the lateral bearing axle of axis hole in slide block；
Described slide block slides between pressing plate and self-lubricating brass sheet, and the material of slide block is wear-resisting steel, or general through Overheating Treatment
Logical steel.
Preferably, described slide block is provided with through grease nipple, and it is yellow with self-lubricating that the outlet of described grease nipple is arranged on described slide block
Between copper coin and between described pressing plate and slide block.
Preferably, it is provided with butter chamber in described slide block.
Preferably, described spring is disk spring.
Preferably, the mounting means of described disk spring is involutory or overlapping.
Preferably, adjustment pad it is provided with between described pressing plate and spring.
Preferably, described self-lubricating brass sheet is pyrite graphite cake.
Preferably, it is provided with reinforcement gusset outside described upper connecting base.
The method have the advantages that
The attachment means of the present invention is provided with the slide block that horizontal direction can relative be slided with lower connecting base, it is allowed to have phase all around
To motion, and hinged by slide block and upper connecting base, make two overlap joint beams to relatively rotate, prevent internal stress；But
Actively push down two overlap joint beams, eliminate the vertical gap between medium-and low-speed maglev track switch two tie-beam, only by adjusting the precompressed of spring
Contracting amount can make two beams overlapped up and down there is precompression, prevents the vibration on vertical direction, the vertical degree of freedom of restraint beam, improves
Magnetic floats the globality of turnout junction girder.
Further, disk spring can compensate the gap that track switch uses abrasion to be caused for a long time within the specific limits, makes underbeam all the time
Withhold together effectively, reduce maintenance times.
The coefficient of sliding friction of the present invention is little, uses between that may extend to slip relatively and that stability requirement is high two overlap joint beams；
Also can change according to the wear condition of slide block and self-lubricating brass sheet and adjust pad, to reach the precompression of regulation, extend and use the longevity
Life.
In addition to objects, features and advantages described above, the present invention also has other objects, features and advantages.Below
Will be with reference to figure, the present invention is further detailed explanation.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the present invention can limit according to claim and cover
The multitude of different ways of lid is implemented.
See Fig. 1, Fig. 2, the attachment means between a kind of medium-and low-speed maglev turnout junction girder, include in case 6 with the first turnout junction girder even
The upper connecting base 4 connect and the lower connecting base 11 being connected with the second turnout junction girder, described lower connecting base 11 is provided with and raises up
Two columns 8.Reinforcement gusset 7 it is provided with outside upper connecting base 4；Upper connecting base 4 is to be provided with downwardly convex welding body, can
Slide relative to lower connecting base.
Being provided with slide block 9 between described column 8, described slide block 9 is pressed on the profit certainly being installed on lower connecting base 11 by pressing plate 3
On the upper surface of sliding brass sheet 10.So, slide block then can slide between self-lubricating brass sheet and the pressing plate on lower connecting base relatively,
Slide block 9 is connected with described upper connecting base 4 by lateral bearing axle 13, then when meeting track switch lane-change outside the two of two beam junctions
While there is the requirement of relative motion all around.
Self-lubricating brass sheet can be structure as a whole with lower connecting base.Slide block 9 is provided centrally with axis hole, and lateral bearing axle 13 may pass through
Axis hole is connected with slide block 9.
Described slide block 9 slides between pressing plate and self-lubricating brass sheet, and the material of slide block can be wear-resisting steel, or through over carburizing,
The common iron of the heat treatment such as nitriding, surface hardening.
