Description
Technical field
The utility model relates to railway truck, especially relates to the hopper car for transporting coal, coke, ore, grain and other bulk freight.
Background technology
The bulk freight such as hopper car prevailing traffic coal, ore, are divided into uncovered by structure and have the large class of lid two.China's hopper car mainly contains the serial hopper cars such as coal, ballast, limestone, ore, cement and grain, the coal hopper car of current China is the surface facility requirement adapting to coal-fired power plant of China, all adopt longitudinal side to start discharging cargo interests formula, its bottom door open-close device independently can be controlled by pneumatic and manual system.Pneumatic operating console and manual transmission are all located on the underframe of car body one end, can control the opening and closing of four bottom doors in both sides simultaneously.Manual transmission adopts reduction box organizations.Pneumaticly to change by power-transfer clutch with manual transmission.Bottom door opening and closing mechanism mainly contains large blade switching mechanism and top locking-type switching mechanism two kinds.
Large blade bottom door opening and closing mechanism action principle is the rack drives pinion rotation be contained in before two way cylinder, the rotation of gear makes the toggle linkage be installed on transmission shaft rotate, promote bottom door short rod and bottom door long draw, because the long and short lever other end of bottom door is connected with bottom door axle, thus drive the opening and closing of bottom door.This mechanism's self-locking property is poor, and bottom door may be caused in operational process from opening.Within 1980, on the basis of this mechanism, add 2 grades of lockings, but to cross l level locking and centering type 2 grades of locking device self-lockings at dead point by machete due to this mechanism, goods will be compressed during enabling, enabling pressure is comparatively large, for addressing this problem, and development top locking-type switching mechanism again.
Top locking-type switching mechanism action principle is the rack drives pinion rotation be contained in before two-way function reservoir, the rotation of gear makes to be installed on the upper crank throw uploaded on moving axis and rotates, the connecting rod composition that rotates through of crank throw drives lower crank throw to rotate, and then drive lower drive shaft to rotate, the toggle linkage be installed on lower drive shaft rotates together, promote short push rod and long push rod, because the long and short lever other end of bottom door is connected with lock body, thus drive the opening and closing of bottom door.Reliable in order to ensure locking, prevent lock body from vibrating from opening when empty wagons runs, between the upper and lower transmission shaft of two-stage transmission, devise one and cross the connecting rod composition just can opened at dead point, lower drive shaft is locked in the turned position of specifying, make lock body be locked in assigned address, define secondary locking states.Open bottom door, when connecting rod is by dead point, the minor rotation of lock body can only be caused at the most.Due to the circular arc that lock body and bottom door pin contacts face are a radii fixus, namely do not compress goods can produce so lock body does not compress funnel door, damping between the friction force that mechanism only overcomes bottom door pressure and produces and each Transmission, therefore enabling power is little.
All there is mechanism's complexity in these two kinds of switching mechanisms, driving efficiency is low, deadweight is comparatively large, the deficiencies such as efficiency is low of unloading coal, lower car body space can not get effective utilization, the raising that the every linear meter(lin.m.) of restriction vehicle Specifeca tion speeification is heavy, exposes the problems such as switching mechanism maintenance is inconvenient, retarder leak tightness is poor, parts are easily lost, wind keyholed back plate road is sewed in utilization process.
