Description
Technical field
The present invention relates to railway locomotive unit brake field, refer in particular to a kind of being used to the used hand alleviation auxiliary device of the unit brake of parking.
Background technology
It is to be with one of unit brake device component part of parking that hand is alleviated, and its function is thoroughly to alleviate the spring parking brake power that the parking brake device produces.The hand relieving apparatus that existing band is parked unit brake is positioned under the car; On operating mode; The hand relieving apparatus need carry instrument or get into and pull relieving apparatus under the car and alleviate, the very inconvenience that operates, and the guideway vehicle that is particularly flowed for the 3rd rail does not possess the safety of operation.
Summary of the invention
The hand relieving apparatus of parking unit brake to existing band is positioned under the car; Inconvenience operates; The guideway vehicle that is particularly flowed for the 3rd rail does not possess the safety of operation, operating mode on, existing hand relieving apparatus need adopt the instrument of carrying or get into and pull the defective that relieving apparatus is alleviated under the car; The present invention aims to provide a kind of hand that is used for the parking brake device and alleviates auxiliary device; Can realize the quick alleviation of parking brake device parking brake power through this device, and simple installation, simple operation.
For solving the problems of the technologies described above, the technical scheme that the present invention adopted is:
A kind of hand that is used for the parking brake device is alleviated auxiliary device, and its constructional feature is to comprise the handle bar pivotally attached connecting rod of parking unit brake with band; The lower end of vertical this connecting rod of arranging is hinged on the rotating plate; One end of the other end of said rotating plate and a horizontal hand lever is hinged, and the other end of this hand lever is a free end, and the medium position of said rotating plate and a bearing are hinged; Bearing is fixed on the seat board, and this seat board is parked unit brake with band and captiveed joint.
Further, be connected through Connection Block between said rotating plate and the hand lever, an end and the rotating plate of this Connection Block are hinged, and its other end is captiveed joint with hand lever.
When needing brake action that the release spring parking brake produces, only need to alleviate auxiliary device and can realize that the spring stop braking thoroughly alleviates through hand.Hand is alleviated auxiliary device and need not on unit brake, newly to open mounting hole, through unborn mounting hole on the unit brake it is installed on and is with on the unit brake of parking.Pull bar on the auxiliary device stretches out the framework outside, stands in car body side pulling hand lever, and the parking brake device is alleviated fast, realizes the convenience and the safety of operation.
Further, said hand lever passes a seat board, and seat board slides relatively, and said seat board is fixedly connected on band and parks on the unit brake.
It between said seat board and the hand lever free-running fit.
The upper end of said bearing is fixedly connected on the seat board.
For the ease of driving the hand lever parallel motion, an end of said hand lever is equipped with elastic cylindrical pin.
Said hand lever and Connection Block be for being threaded, and this junction is equipped with nut, between nut and Connection Block, is provided with spring washer.
By said structure, hand is alleviated the spin-block rotating mechanism in the auxiliary device, and the unit brake upper handle pull bar that band is parked moves downward the parallel motion that converts hand lever through rotating mechanism into.The size of alleviating position, spin-block and the connecting rod of bearing in the auxiliary device through hand guarantees to make handle bar can reach thorough release position through hand lever being applied certain power.
Hand alleviation auxiliary device is installed on the parking brake device through the mounting hole of parking brake device self; The mounting hole that utilizes band to park to exist originally on the unit brake is hand alleviation auxiliary device fixedly; The displacement scale of handle bar when alleviating the spin-block rotating mechanism assurance hand relieving on the auxiliary device through hand; Required pulling force is alleviated pulling force near parking brake device design-calculated hand in the time of simultaneously also guaranteeing hand relieving, guarantees that the unit brake that can on function, not park band is influential; Alleviate at hand on the mounting means of auxiliary device and unit brake, adopt bolted connection.
According to the preferred version of embodiment, hand is alleviated the auxiliary device parts and is adopted ferrous materials commonly used and gauge member, and the assembling performance is good, convenient disassembly.
Compared with prior art, the invention has the beneficial effects as follows:
1, after hand was alleviated the auxiliary device installation, the hand relieving operation compared of parking brake device did not have auxiliary dress
More convenient when putting, safety;
2, alleviate auxiliary device through hand and the parking brake device is reached alleviate the position fully, required pulling force with
Hand relieving power basically identical during no auxiliary device;
3, hand is alleviated the auxiliary device installation, changes, is dismantled simply.
