Abstract
The utility model provides a pedal brake chain winding device for railway freight train, comprising a winding chain wheel inside the casing and a coaxial eccentric oscillating weight. At the moment of the relieving procedure finishing, the winding chain wheel interacts to the lug of the eccentric oscillating weight with the flange radius jump link stopper, the flabby part of the manpower brake chain is tautened and kept quickly, to finish the next brake with convenience and rapidity, and even the power of brake can be mediated directly to carry out stage brake. The pedal brake chain winding device can make the performance of the pedals brake more perfect, which profits to the mediation and group work of the railway freight train to adapt the needs in new period railway transportation.
Description
The invention belongs to railway truck brake equipment technical field, is specifically related to a kind of perfect performance of preventing the foot-operated brake of slide and terrestrial operation with manual braking, alleviation, graduated application, locking.
So far the general purpose freight car of china railway on-line operation has nearly ten thousand and has installed " railway truck lever foot brake machine " (number of patent application: 90221403.9,95215144.8).This machine is gone through more than 4 years in thread test and test operation, and its performance is described as railway truck manual braking's revolution by the particularly vast braking person's of the relevant expert of the Ministry of Railways approval and give favorable comment.Domestic lorry master makes producer and newly makes the railway general purpose freight car and adopted " foot-operated brake (Ministry of Railways's code designation) " basically entirely, and the problem that the vertical shaft type hand brake of incompatibility railway modernization exists is completely resolved, is substituted progressively that the die is cast.But requiring braking person must expertly grasp operation skill, foot-operated brake can give full play to its excellent performance.
The purpose of the invention will provide a kind of operation skill of emphasizing within reason still can implement quickly and easily to alleviate exactly---and the braking cycle event even chain winder braking can directly reconcile the braking force size implementation phase makes foot-operated brake performance more become perfect.
The invention is to former patent (number of patent application: improvement 95215144.8), change newly-designed around sprocket wheel and cancellation with around the adjustment cover of sprocket coaxiality, on the position of adjusting cover, changed the outfit newly-designed with around the supporting eccentric pendulum of sprocket wheel, two parts can make the operation of foot-operated brake only need stepping of 1 to 2 pin just can implement to brake even graduated application by the mutual action of projection and flange radius jump link stopper.Principle of work: when foot-operated brake was in braking mode, it is sagging that eccentric pendulum with the axle is by deadweight that hinge rotates naturally, do not act on around sprocket wheel; When the moment that foot-operated brake is alleviated, around sprocket wheel reversing rapidly under the drag chain tension, act on eccentric pendulum projection by flange radius jump link stopper, it is turned to by the spacing back of the reinforced rib in the housing reverses, it is stirred around chain wheel rim radius jump link stopper by the projection of self again conversely under the effect of pendulum deadweight, make around sprocket wheel by rotating around chain, strained the drag chain that souththern pine relaxes again around chain direction.The slack of alleviating the back drag chain is tightened up again, and foot-operated brake still is in the core that relieved state is the art of this patent theory.The feasible foundation of principle: the foot-operated brake of railway truck device is under 125 millimeters the prerequisite at wind brake cylinder stroke, pedal brake chain stroke be 290 to 340 millimeters comparatively desirable, braking person steps 8 to 9 pin can implement braking.By the braking rule, for railway truck, the drag chain effective travel has only 60 millimeter, these the 60 millimeters elastic deformations that come former in car load braking rod member, the bearing pin gap, the accumulation of factors such as wheel rim and brake clearance size, all the other all are idle travels, braking person just begins to enter the deboost phase after will giving and stepping 6 to 7 pin earlier in other words, step 1 to 2 pin again and could implement braking or graduated application, particularly graduated application is concerning the braking person who grasps operation skill, reconcile the braking force size without a doubt, but concerning operating unskilled braking person, acquire a certain degree of difficulty.Eliminated idle travel in advance, only need step that 1 to 2 pin can be implemented braking even braking directly the implementation phase through the chain winder of redesign.Eccentric pendulum itself is exactly a counterweight, its role is to drag chain weight that balance relaxed and around the chain radius do not wait around the laying particular stress on of sprocket wheel, torsion has only several kilograms.
The invention can make foot-operated brake performance more perfect, only need step 1 to 2 pin and can implement braking even graduated application, modulation within reason is mobilized operation skill, making alleviation---the braking cycle event is faster, more help the railway truck grouping operation of shunting, with the requirement of the railway transportation that adapts to the New Times.
Below in conjunction with accompanying drawing this patent implementation example is illustrated.
The normal braking mode of Fig. 1, principle schematic: A, B are alleviated moment, the normal relieved state of C, and e hammers bolt into shape for hanging among the figure, f is that drag chain, g are that pendulum projection, h are radius jump link stopper.
Fig. 2, structure drawing of device.
See accompanying drawing.Newly-designed key way for sleeping in around sprocket wheel [2] makes single radially spiral into around chain by original axially and radially spiral in the housing [1], minimum changes greatly R70 millimeter around the chain radius, radially in chain radius R 70 to R76 millimeter scopes, flange radius is the R88 millimeter, and all the other radiuses still are the R108 millimeter, and radius jump place has 20 * 12 millimeters, angle is 15 ° link stopper h, still use raw MAT'L QT450-10, the more former wheel of weight alleviates 5 kilograms, and technology is more former takes turns simply; With eccentric pendulum [3] geometric shape around sprocket wheel [2] coaxial cooperation be the fabricate block of thick-walled pipe and secter pat, near have around 90 millimeters places of sprocket wheel [2] end secter pat radius R 12 * 18 * 25 millimeters projection g with around sprocket wheel link stopper h mutual action, secter pat itself is a counterweight, and its weight is spacious according to railway, the corresponding weight of a canopy freight car braking f is determined.Secter pat itself also is a limiting stopper, is retrained by housing [1] reinforced rib.
This device is suitable for the first tension of giving with the foot-operated brake braking of railway truck chain.
Claims (1)
- The chain winder of the foot-operated brake of a kind of railway truck, by being formed in the housing [1] around sprocket wheel [2] and coaxial eccentric pendulum [3], it is characterized in that installing have spiral radially crouch key way around sprocket wheel [2] by self flange radius jump link stopper with have the projection mutual action of the eccentric pendulum [3] of counterweight function, the slewing area of eccentric pendulum [3] is retrained by the reinforced rib in the housing [1].
