Abstract
The utility model relates to a hand brake plate which is especially used for wrenching fixed rotating type hand brake machine detent roller on the railway wagon, comprising a clamping shaft sleeve, a wrenching flap base, a wrenching flap and a handle. The wrenching flap base is a slot-shaped member the two upright edges of which have unequal height. The inward bend is arranged on the upper end of the higher upright edge. A wrenching flap shaft is fixed on the wrenching flap. Both ends of the wrenching flap shaft are installed on the two upright edges of the wrenching flap base, and both ends of the wrenching flap shaft can be freely rotated. The centre of the gravity of the wrenching flap is positioned at one edge of an anti-wrenching direction of the hand brake plate. The hand brake plate has the advantages of simple and reasonable structure and flexible and convenient use. The hand brake plate can completely achieve the brake effect of wrenching the hand wheels of the hand brake machines.
Description
The utility model relates to a kind of railway truck Hand brake bar, is the special tool that is used for pulling fixed type hand brake detent roller on the lorry.
Existing railway truck is equipped with the fixed type hand brake mostly, and the hand braking handwheel of this rim brake is positioned at the roof top, must step on the hand brake pedal during use and could move.Make electric locomotive into because original steam locomotive now more, frame has contact line conducting wire along the railway, and to get on to pull hand braking handwheel at the hand brake pedal be breakneck as also stepping on, and like this, original fixed type hand brake just can't continue to have used.
The purpose of this utility model provides a kind of special tool that is used for pulling fixed type hand brake detent roller---Hand brake bar.Reach the braking effect that the hand braking handwheel of original rotation could be realized by the switching detent roller.
The utility model Hand brake bar mainly comprises axis cover, cock tongue seat, pulls tongue and handle.Cock tongue seat is one two channel member that vertical edge is not contour, and on the higher vertical edge an inside bending is arranged, and is used for limiting the position of Hand brake bar when operation, in order to avoid slippage.Pull and be fixed with cock tongue shaft on the tongue, the cock tongue shaft two ends are contained on two vertical edges of cock tongue seat, and cock tongue shaft is free to rotate.Therefore the center of gravity of pulling tongue is not on cock tongue shaft, and center of gravity is positioned at Hand brake bar and moves back the one side of pulling direction, pulls tongue and always is upturned advancing to pull direction.The diff-H of two vertical edges of cock tongue seat should be not less than the thickness (height that comprises tooth on the detent roller) of hand brake detent roller, so that insert detent roller.The height (at perk end height) of pulling tongue should exceed the low limit of cock tongue seat, and exceeding height can be selected according to the diff-H and the tooth depth on the detent roller of two vertical edges of cock tongue seat, and to insert the position of the tooth on the detent roller moderate so that pull tongue during the Hand brake bar operation.General, two vertical edge diff-Hs are similar to detent roller thickness, pull tongue and exceed about half tooth depth in the low limit of cock tongue seat.The axis cover is a camber member, and its effect is to be stuck in to play point action on the hand brake mast when pulling Hand brake bar.The axis cover can be fixed in the outside of the low vertical edge of cock tongue seat, also can be fixed on the crooked edge section of stretching in the higher vertical edge of cock tongue seat upper end.Handle is fixed in the higher vertical edge of the cock tongue seat outside, and for easy to use, handle becomes one greater than 90 ° of obtuse angles with the cock tongue seat channel-section.
The utility model Hand brake bar is simple and reasonable, easy to use flexible, just only need stand on the handrail hand brake detent roller fastenedly, and can reach fully and pull the braking effect that hand braking handwheel reaches, play a role again thereby can make at electrified sections withdraw from service fixed type hand brake.
Two embodiment below in conjunction with description of drawings the utility model Hand brake bar:
Fig. 1 is an embodiment of the present utility model.Axis cover 1 is a camber member, has two work segmental arcs, and big segmental arc plays point action, and the effect of little segmental arc is slippage when preventing retaining plate.Axis cover 1 is welded on the edge section of stretching 3 of curved end of the higher vertical edge 4 of plate tongue seat, and reinforced rib 2 play fixed supporting role.It is fixing with cock tongue shaft 7 to pull tongue 6, in the hole 5 that cock tongue shaft 7 inserts on cock tongue seat two vertical edges, and free to rotate.Handle 8 is welded on the higher vertical edge of cock tongue seat 4 outsides, and handle 8 is 120-135 ° with the angle of cock tongue seat channel-section.
Fig. 2 is another embodiment of the present utility model.Axis cover 1 is a tabular component with arc bayonet socket, is welded on the outside of the low vertical edge 10 of cock tongue seat.Pull tongue 6 and be welded on the cock tongue shaft 7, also free to rotate in the hole that cock tongue shaft 7 inserts on cock tongue seat two vertical edges.Handle 8 is welded in the outside of the higher vertical edge 4 of cock tongue seat, and becomes 130 ° of obtuse angles with the cock tongue seat channel-section.There is one section inside bending 9 the higher vertical edge of cock tongue seat 4 upper ends.
Claims (3)
1, a kind of Hand brake bar of pulling fixed type hand brake detent roller on the railway truck that is specifically designed to is characterized in that this Hand brake bar comprises axis cover, cock tongue seat, pulls tongue and handle; Cock tongue seat is one two channel member that vertical edge is not contour, and there is an inside bending higher vertical edge upper end; Pull and be fixed with cock tongue shaft on the tongue, the cock tongue shaft two ends are contained on cock tongue seat two vertical edges, and free to rotate; The center of gravity of pulling tongue is positioned at Hand brake bar and moves back the one side of pulling direction, and the diff-H of two vertical edges of cock tongue seat should be not less than the thickness of hand brake detent roller (height that comprises tooth on the detent roller), pulls tongue and should exceed the about half detent roller tooth depth in the low limit of cock tongue seat at the height of perk end; The axis cover is an arc component, is fixed in the outside of the low vertical edge of cock tongue seat; Handle is fixed in the higher vertical edge of the cock tongue seat outside.
2, Hand brake bar as claimed in claim 1 is characterized in that handle becomes greater than 90 ° of obtuse angles with the cock tongue seat channel-section.
