Description

Special dipperstick of track traffic bow net antithetical couplet accent

Technical Field

The utility model relates to a city rail traffic contact net specialty maintenance technical field, in particular to track traffic bow net allies oneself with transfers special dipperstick.

Background

The matching degree between the pantograph and the contact network in the rail transit industry directly determines the safe operation reliability of the electric locomotive. At present, a default pantograph for maintenance and adjustment of a contact network is absolutely flat, no abnormal shaking occurs during operation, and a rail is used as a reference object and is adjusted by using a laser measuring instrument static measurement method. The inspection of the pantograph by the vehicle profession is subject to the flatness of a single pantograph, and the standard of the consistency of all pantographs is not intentionally pursued. Therefore, the two sides are not overhauled according to the unified standard, the possibility of unmatched pantograph nets exists, errors in overhauling can be superposed and amplified, and abnormal abrasion is inevitably caused in the operation of the pantograph due to the defect of sine wave design of an early rigid catenary. The maintenance modes of the two major can not reflect the real bow net relationship, and a special inspection and adjustment scheme and a special inspection and adjustment tool for matching bow nets do not exist all the time along with the rapid development of urban rail transit. In the field of rail transit, the geometrical parameters of the pantograph-catenary are in millimeter level, and small unevenness can cause bad pantograph-catenary relation, ignition, arc discharge, damage and the like, so that the driving safety is damaged.

Detailed Description

The present invention will be described in further detail with reference to examples.

As shown in fig. 1-2;

the utility model provides a bow net allies oneself with transfers special dipperstick, includes main scale 1, both ends contain separately on the main scale 1 and keep off lock 2, horizontal bubble 3 and prevent spacer 4, and 333 dog 5 are installed to the inner core, and the dog can freely reciprocate.

The main ruler 1 adopts a plastic mold opening structure, and comprises an anti-support baffle 4 when the mold is opened, and a horizontal blister 3, a baffle lock 2 and an inner core position are reserved. 333 check blocks 5 are precisely installed on the inner core, the check blocks can freely move up and down, horizontal bubbles 3 are installed at reserved positions to achieve horizontal observation, and the check locks 2 achieve locking after the check blocks 5 are subjected to mold taking.

As shown in figure 1, comprises a main scale 1, a length of 800mm, a width of 44mm, a thickness of 20mm, a hollow inner core with a length of 500mm, a width of 44mm and a thickness of 5mm. The stop locks 2 are embedded into two sides of the main ruler 1, and are 20mm long and 44mm wide. The inner long lock catch is contacted with the stop block 5, and the stop block 5 can move freely when the stop lock 2 is pulled upwards; the stop 5 is locked when the catch 2 is pulled down. 2 horizontal blisters 3 are respectively embedded into two sides of the main scale 1, the length of the blisters is 40mm, the width of the blisters is 10mm, the thickness of the blisters is 10mm, and the 2 horizontal blisters 3 are respectively parallel to the length and the width of the main scale 1 and used for measuring whether the main scale 1 is horizontal or not in an auxiliary observation mode. 333 blocks of stoppers 5 are arranged on the inner core of the main scale 1, as shown in fig. 2, the stoppers 5 are 130mm long, 1.5mm wide and 5mm thick, can freely move up and down in the hollow inner core of the main scale 1, and have protrusions with thickness larger than 5mm on two sides to prevent the stoppers from falling out of the hollow inner core of the main scale 1. In order to ensure that 333 blocks of stop blocks 5 are tightly attached, two sides of the hollow inner core of the main scale 1 are connected with 2 anti-support blocks 3262 zxft 3238 with the length of 25 zxft 3238, the width of 54mm and the thickness of 20mm, the width of 500mm in the middle of the anti-support blocks 3262 is the same as the length of the inner core of the main scale 1, and therefore 333 blocks of stop blocks 5 are tightly attached without gaps.

The utility model discloses a theory of operation:

after the stop lock 2 is opened before use, the main ruler stop block part is contacted with the pantograph to be tested, the horizontal condition is observed, the stop lock 2 is locked after the main ruler stop block part is kept horizontal and completely attached, and the mold taking of the carbon slide plate abrasion of the pantograph is completed. Utilize this device to keep off chi part and snatch each pantograph wearing and tearing condition, draw the average wearing and tearing point of line train of wearing and tearing curve calculation, polish by the vehicle specialty to the pantograph that surpasss for the carbon slide wearing and tearing of each pantograph are the same basically. The contact net specialty adjusts key equipment according to the average value of snatching again, guarantees that the parameter of key equipment is the same with the wearing and tearing of pantograph. And parameters of each pantograph and each contact network parameter joint equipment are matched with each other. The potential factors of different pantographs damaging equipment such as a section insulator, an anchor section joint and the like are eliminated, and the occurrence of arc discharge and ignition among pantograph meshes is improved.
