General run of thins, the antenna equipment of guideway vehicle signal system is generally arranged on car body, but along with vehicle parking accuracy requirement more and more higher, signal system is thought due in vehicle operation, the displacement of car body is comparatively large, can affect stability and the precision of antenna equipment work.And on whole guideway vehicle, the dynamic displacement of bogie truck is minimum, existing settling mode is arranged on bogie truck by antenna equipment, little on the signal system impact of antenna equipment, but it is compact that Problems existing is bogie structure, inner space is limited, is difficult to meet large-size or without the larger antenna equipment of metal area; Also technical personnel is had to consider antenna equipment to be arranged on bogie truck two ends, but because current truck frame is generally " H " type, end carriage is not had to fix up an aerial wire, if be welded with an end carriage, all larger impact can be caused on the rigidity of structure of truck frame, intensity and manufacturing process, need to carry out a large amount of tests to framework, not only need the expense of great number but also delay project process.
Utility model content
For solving the problems of the technologies described above, this practicality provides a kind of antenna equipment anchor fitting for guideway vehicle, and it is by arranging an end carriage, is fixed on by antenna equipment on end carriage and realizes improving the stability of signal system and the object of precision.
For realizing above-mentioned technical purpose, the concrete scheme that this practicality is taked is:
For an antenna equipment anchor fitting for guideway vehicle, comprise two mount pads, end carriage and antenna equipment mount pad; In the rearward end of the truck frame both sides of guideway vehicle, fix aforesaid two mount pads respectively; Each mount pad all with mounting hole, and installs end carriage by described mounting hole, and end carriage is positioned at the rear of rail vehicle truck; Described antenna equipment mount pad is fixed on end carriage midway location.
As the preferred technical scheme of this practicality, also comprise the rubber nodal point with through hole and node seat; Described end carriage runs through the through hole of rubber nodal point; Described rubber nodal point and node seat interference fit; Described node seat is fixed on mount pad by unit bolt nut.
As the preferred technical scheme of this practicality, the termination of described end carriage is threaded, and end carriage adopts retaining washer after running through the through hole of two rubber nodal points, end carriage and rubber nodal point are locked by the screw thread fit of jam nut and end carriage termination.
As the preferred technical scheme of this practicality, described node seat is with dome, and node seat adopts unit bolt nut to be fixed after the mounting hole interference fit of dome and mount pad.
As the preferred technical scheme of this practicality, described mount pad at the contact surface of the truck frame curb girder rearward end with guideway vehicle with boss; The truck frame curb girder rearward end of described guideway vehicle with the contact surface of mount pad with the groove corresponding with boss, mount pad after the groove fit of the truck frame curb girder rearward end by the boss on mount pad and guideway vehicle is fixed on the truck frame curb girder of guideway vehicle, then adopts bolt to be fixed
The beneficial effect of this practicality
1. this practical end carriage is connected, on truck frame agent structure without impact with framework left and right curb girder rearward end bolt by two mount pads; Adopt rubber nodal point between mount pad and end carriage, end vibration of beam can be reduced, and then reduce end carriage to the impact of framework, be unlikely to increase the rigidity between the curb girder of truck frame left and right simultaneously, drop to minimum on truck frame impact.
2. the boss adopted between mount pad and truck frame and groove fit, the tie bolt between mount pad and truck frame by vertical shearing force, not ensure that the stability of antenna equipment anchor fitting; And mount pad endoporus and node seat dome adopt transition fit, tie bolt is not by shearing force.
3. interface flexibility, wide adaptability, this end carriage midway location arrange antenna equipment mount pad can with the changing of design excuse of different bogie truck and antenna equipment, can be used for various different bogie truck and antenna equipment, comformability is widely.
