Description

Railway locomotive cab vibration damping regulating method

Technical field

The present invention relates to a kind of railway locomotive cab vibration damping regulating method, belong to the railway locomotive technical field.

Background technique

Railway locomotive is the high powered diesel locomotive of high-speed overload especially, and transferring energy is huge, and the vibration-generating problem is also more frequent.The harm of locomotive vibration is huge, not only affects the life-span of component on the locomotive, also can cause driver and conductor's serious discomfort, and is very unfavorable to the safety traffic of train.The vibration isolation form of internal combustion locomotive mainly contains two kinds: a kind of is active vibration isolation, and namely the driver's cab rigidity is installed on the underframe, and the transmission that elastic support reduces vibration is installed between diesel generating set and vehicle body bottom frame; Another kind is passive vibration isolation, is about to the diesel generating set rigidity and is installed on the vehicle body bottom frame, and mounting spring and damper, rubber bush bearing vibration damper etc. are to reduce the vibration of driver's cab between driver's cab and the underframe.When the vibration of passive vibration isolation locomotive cab occurs, how effectively to regulate, the vibration that reduces driver's cab is very important.

Prior art must be removed all pipelines and connected element to the driver's cab overall pulling down when locomotive cab is regulated, then regulate.Reinstall driver's cab after the adjusting, connect all pipelines and connected element, just can restart locomotive and carry out obtaining of vibration data.If situation is not improved, must again remove driver's cab and regulate, just can obtain new vibration data after the recovery.This mode expends a large amount of manpower and materials and time, need to adopt a large amount of equipment, the being dismounted for multiple times driver's cab, and can't be in real time, the continuous acquisition vibration data, know the adjusting situation of vibrating.

Summary of the invention

Purpose of the present invention overcomes the deficiency of above-mentioned prior art exactly, provides a kind of need with few, the easy and simple to handle railway locomotive cab vibration damping of equipment regulating method.

The object of the present invention is achieved like this: a kind of railway locomotive cab vibration damping regulating method is characterized in that taking the following step:

A. for each elastic member compressing mechanism is set;

B. with described elastic member with compressing mechanism with the bottom of driver's cab be connected wall and be connected with the partition wall that underframe is connected with adjacent functional respectively;

C. regulate respectively the compressing mechanism of each elastic member, change the rigidity of elastic member, until the driver's cab level of vibration meets the requirements.

Adopt the solution of the present invention, can carry out easily and effectively the vibration of passive vibration isolation internal combustion locomotive and regulate, need not lift by crane driver's cab, need not to carry out a large amount of dismounting and resume work, do not need various frocks, suspender, equipment only relies on simple pneumatic impact wrench effectively to regulate.Saved a large amount of manpower and materials times, and can carry out immediately the collection of vibration data after regulating, be optimized adjustment, the vibration problem that not only is used for the rear locomotive of assembling is processed, and also can be applied in the process of experimental of vibration problem.

Number in the figure: the fitting seat on the 1-driver's cab, 2-spring, 3-U type socket pad, supporting base on the 4-underframe anticollision mechanism, 5-jackscrew, 6-adjusting bolt, the 7-pad, the fitting seat under the 8-driver's cab, 9-vibration damper, fitting seat on the 10-underframe, 11-underframe, the partition wall of the functional compartments that 12-and driver's cab are adjacent, wall behind the 13-driver's cab, 14-steel structure, 15-damper, the 16-jackscrew, 17-jacking block, 18-stiffening plate.

Embodiment

For the purpose, technological scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technological scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiments.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment who obtains under the creative work prerequisite.

Referring to Fig. 1, the compressing mechanism of driver's cab bottom spring is comprised of jackscrew 5, supporting base 4 and U-shaped socket pad 3.Jackscrew 5 is threaded, spring supporting seat 4 integrates support and jackscrew adjustment seat, by regulating jackscrew 5, change the decrement of spring 2, make between spring 2 and the supporting base 4 and produce the gap, thereby can successfully U-shaped socket pad 3 be inserted, change the rigidity of spring 2 by the compression height of Regulation spring 2, change the driver's cab stress, play the effect that vibration is regulated.

Referring to Fig. 2, the rubber bush bearing vibration damper for the driver's cab bottom couples together the fitting seat 10 on the fitting seat 8 under the driver's cab, vibration damper 9 and the underframe 11 by adjusting bolt 6 and pad 7.Tight, vibration damper 9 decrements increase with bolt 6, and rigidity increases; Bolt 6 is unclamped, and vibration damper 9 decrements reduce, and rigidity reduces.By this kind mechanism and Placement, vibration damper 9 has become adjustable vibration damper in the certain limit.Thereby regulate the vibrational energy that passes to driver's cab from underframe, thereby the adjusting of vibrating.

Referring to Fig. 3, the elastic connecting device of wall adopts jackscrew 16, jacking block 17, hydraulic cylinder damping device 15 and stiffening plate 18 to form behind the driver's cab.The size that jackscrew 16 and jacking block 17 are used for regulating support force, stiffening plate 18 is used for guaranteeing the reliability of power transmission between the structure, oil hydraulic cylinder 15 serves as damping, is used for absorbing vibrational energy, reaches the function of regulating vibration.
