Abstract
The utility model discloses an empty weight handle automatic transferring device for rail vehicles. The utility model is characterized in that according to the change of the loading capacity of vehicles, by using the fall of a swing bolster (19) and a side frame (20), a proportional amplifying lever assembly is composed of a baffle plate (1) arranged on the side frame, and a lever drive arm (2) and a lever power arm (6) which are arranged on the swing bolster, and a swing link (4). An action pull rod (11) and an empty weight handle transferring pull plate (16) are driven by the lever power arm (6) under the action of the tension of an action spring (7) arranged on the lever power arm (6), and an empty weight handle (17) is driven to transfer automatically.
Description
The utility model relates to a kind of rolling stock bare weight handgrip automatic exchanger.
The adjustment of rolling stock bare weight handgrip, be vehicle at sky, loaded vehicle when operation, determine a kind of control device of braking force power, to guarantee that train safe normally moves.Rolling stock bare weight handgrip is by manually changing at present.When vehicle is loaded with goods, need artificially to transfer the bare weight handgrip to loaded position, after unstowing, goods must transfer the empty wagons position to, just can enroll sharp car operation.If do not change the bare weight handgrip on request, in heavy duty, high speed train generation glancing impact, when car brakeing power is strong excessively, be easy to cause the vehicle band-type brake, make the vehicle wheel flat sliding, otherwise car brakeing power is not enough, causes vehicle to collide mutually, and perhaps overrunning of signal jeopardizes traffic safety.At interval station on the way, behind the vehicle handling goods, check that without the vehicle department technology vehicle bare weight handgrip is difficult to reach normotopia and enrolls train operation especially,
The purpose of this utility model is at above-mentioned weak point, and a kind of component composition is provided, and simple installation is safe and reliable, is convenient to vehicle again when maintenance, and demolition is rolling stock bare weight handgrip automatic exchanger easily.
The utility model is achieved in that it is to change according to the load carrying ability of vehicle, because under the bolster pressure effect of bearing body, bolster spring produces a stroke, makes and produces a drop amount between bolster and the bogie side frame.It utilizes the drop amount that produces between bolster and the bogie side frame, by the baffle plate and the leverage arm and the lever moving arm that are installed on the bolster that are installed on the bogie side frame, and pivot link, the leverage of forming a proportional amplification, with the drop amount of bolster and bogie side frame, zoom into the variable quantity of a trip distance.By being installed under the operating spring tension on the lever moving arm.By lever moving arm, induced effect pull bar and the conversion of bare weight handgrip are drawn and are pulled, and the bare weight handgrip is changed automatically, reach the purpose of adjustment,
The utility model has following advantage and effect: this device can be followed according to the vehicle load situation and be realized the conversion of bare weight handgrip automatically, reduce the car brakeing fault that human element causes, guarantee safe train operation, can also follow actual requirement according to railway all kinds vehicle, only need to consider minimum drop amount between bolster and the bogie side frame, calculate ratio between leverage arm and the lever moving arm, the moving transfer device of bare weight handgrip order just can be installed on various types of vehicles.Install for convenience and decompose car body when adjusting this device and car inspection and maintenance, the spy is provided with the empty wagons positioning regulator and overhauls demolition Lantern Festival.
Below in conjunction with accompanying drawing the utility model is described in detail:
Fig. 1 is a utility model accessory scantling plan.
Fig. 2 is the utility model front view.
Fig. 3 is the utility model birds-eye view.
Fig. 4 is a conversion pulling plate structure scheme drawing
With reference to accompanying drawing: when vehicle is in complete vehicle curb condition, because car body (22) is in light weight, bolster (19) to relatively not compression of body spring (21), bolster (19) keeps relative equilibrium with bogie side frame (20) State, at this moment, owing to be welded in the effect of the baffle plate (1) on the bogie side frame, leverage arm (2) and side Frame (20) is in level, and at this moment lever moving arm (6) is in state to the right, so that the action bullet Spring (7) elongates, and is in to right conversion through cross connector (9) induced effect pull bar (11) Arm-tie (16) drives bare weight handgrip (17) left, makes bare weight adjust cock (18) and is in opening Finish the empty parking space conversion.
When car body was equipped with goods and is in the loaded vehicle state, the weight of car body (22) was by bolster (19) Body spring (21) is compressed, and bolster (19) descends simultaneously, bolster (19) and bogie side frame (20) Between produce a drop so that produce the gap between leverage arm (2) and the baffle plate (1), by Holder (3) in pivot link (4), (5) are to be positioned on the bolster (19), in operating spring (7) The pulling force effect under so that lever moving arm (6) is moved to the left, by pivot link (4) so that Leverage arm (2) moves up, and lever moving arm (6) drive cross connector (9) makes simultaneously Effect pull bar (11) is moved to the left, and drives conversion arm-tie (16) through positioning regulator (13) and moves to sheet Moving, bare weight handgrip (17) makes bare weight adjust cock (18) and is in closed condition to the right, finishes heavily The parking stall conversion.
In order to keep vehicle in curve motion, the rotation spirit between bolster (19) and the car body (22) Live, adopt cross connector (9), this device is installed in bolster is connected accessory with car body and connects , when installing or overhauling this device, as long as positioning regulator (13) is adjusted normotopia with empty parking space, just Can protect just this device normal operation, when vehicle need to decompose maintenance, overhaul Lantern Festival as long as discharge (10), just this device can be resolved into two parts, i.e. body part and bogie part are among the figure (12), (14) are effect pull bar carriage, and (15) are conversion arm-tie fixed support.
Implement example: C62A type vehicle for example, drop is 30 to 40MM between its normal loaded vehicle (601) and empty wagons bolster and the bogie side frame, and the conversion stroke of bare weight handgrip is about 150MM, for the load-carrying of considering vehicle has only a half, can carry out the bare weight conversion, therefore the leverage arm of this device is 1: 3 with the ratio of lever moving arm, the arm of force length that is the leverage arm is 70MM, and lever moving arm arm of force length is 210MM, the conversion of this device draw pull OA and OB length ratio be 1: 5 be that OA is 60MM as Fig. 4, OB is 300MM, and bolster and bogie side frame drop are as long as just can turn to loaded position by the empty wagons position with the bare weight handgrip greater than 10MM like this.
