Abstract
A point switch-used roller trailing device comprises an adjusting nut 1, an adjusting shim 2, a disc spring 3, a trailing post 4, a contact 5 and a lock rail 6, and is characterized by also comprising a roller 7, the roller 7 is positioned between the trailing post 4 and the lock rail 6; the lock rail 6 is provided with a groove 8 in which the roller can be inlaid; and the lower part of the trailing post is provided with a rolling groove 9 in which the roller can be inserted. Since the roller is used to replace the trapezoid convex plate, so the phenomenon that the trailing post can not separate from the lock rail when in inclined trailing, but can move up and down with the change of the external force, the surface of the part can be worn, and the geometric dimension changes, so the force required by the trailing becomes small is eliminated, and simultaneously the effect of the friction force to the force required by the trailing is reduced.
Description
Technical field
The utility model relates to a kind of switch machine, particularly relates to the crowded device that takes off of the roller that uses on a kind of switch machine.
Background technology
Switch machine is the actuating unit of track switch control system.Be used to change locking point tongue or heart rail, the position and the state of point tongue or heart rail in the expression supervision interlocking area.Squeeze track switch generation under the situation of trouble, can the track switch conversion equipment adapt to, promptly squeeze trouble generation back track switch conversion equipment and can cut off switch indication by failure-free, the fast quick-recovery of energy after can not being damaged or being damaged, can not influence driving or reduce influences running time, just becomes very important problem.
Can squeeze the type switch machine and after squeezing trouble, can disconnect the switch indication circuit, protection switch machine and conversion locking device and point tongue.The ZD9 type electric switch machine branch of present domestic use can squeeze and can not squeeze two kinds on type; the principle that the type that can squeeze squeezes: when squeezing trouble switch pole stressed surpass specified squeeze take off power after; squeeze and take off the post disengagement, the throw rod release reaches the function of cutting off switch indication circuit and trap points.As shown in Figure 1, it adopts the crowded device that takes off in an inclined-plane to realize squeezing the function of taking off.Contact seat 5 is fixed in the switch machine, squeeze the round bar take off post 4 tops and partly be with several dish springs 3, adjustment nut 1 is pushed down dish spring 3, and is tightened on the contact seat 5, the dovetail groove that squeezes the trapezoid boss 11 embedding locking iron 6 that take off post 4 bottoms is interior and compacted, thereby makes the position of locking iron also fixing.When external force acted on the locking iron, the inclined-plane by trapezoid boss 11 had component upwards to act on the dish spring, when external force enough greatly the time, dish spring 3 is compressed, squeeze and to take off post 4 and rise, finally make locking iron 6 and crowdedly take off post 4 and separate, provide signal by a warning device in the switch machine simultaneously.In this device, make locking iron and squeeze the size take off the power that post breaks away from and mainly determined by the angle on dish spring, inclined-plane and the physical dimension of each part, the friction between part.
Squeeze in the structure take off on the inclined-plane, take off post and can not guarantee unanimity with bevel angle and the relevant physical dimension of locking iron if squeeze, then make locking iron and crowded power of taking off the post disengaging with regard to wayward on a constant value.In addition in actual use, the power that acts on locking iron is the power that changes, though it can cause squeeze take off post do not break away from locking iron groove can be along with the power up-and-down movement of this variation, cause and squeeze the mutual friction mutually take off between post and locking iron inclined-plane, cause the variation of part geometry size, final when external force does not also reach predefined value, locking iron just breaks away from the crowded post that takes off, and causes a hidden danger of switch machine device.
The utility model content
The purpose of this utility model is to provide a kind of crowded device that takes off of roller construction at the existing deficiency of taking off device of squeezing, and guarantees to have only when external force increases to the value of a preliminary election setting, could take place to squeeze and take off phenomenon.
The technical scheme that the utility model adopted is: a kind of switch machine squeezes with roller and takes off device, comprise adjustment nut 1, bearing cap shim 2, dish spring 3, squeeze and take off post 4, contact seat 5, locking iron 6, it is characterized in that: also comprise a roller 7, described roller 7 takes off between post 4 and the locking iron 6 crowded, locking iron is provided with the groove 8 that can embed roller, squeezes to take off the post bottom and be provided with the slot rolling 9 that can insert roller.
Further, the described crowded slot rolling 9 that takes off the setting of post bottom is under shed, and described opening is less than the diameter of roller.
The described end that takes off post bottom slot rolling 9 that squeezes is provided with the boss 10 that the restriction roller moves.
Owing to use roller construction to replace trapezoid boss, the one, the friction force of friction of rolling is less than the friction force of inclined-plane cliding friction, the 2nd,, roller begins to take place the needed external force maximum of rolling, promptly roller can not roll when external force does not reach the power value that sets, and in a single day reaches this setting value and work as external force, after roller rolls, its the required external force of keep rolling will be reduced immediately, so the power value of roller when taking place to roll is maxim.The beneficial effect of roller construction is: though one, eliminated the inclined-plane and squeeze to squeeze in taking off and take off post and do not break away from locking iron, but can be along with the crowded post up-and-down movement that takes off of the variation of external force, piece surface wearing and tearing, physical dimension are changed, take off the phenomenon that required power diminishes thereby cause taking place squeezing.Two, since the friction force of friction of rolling less than the friction force of inclined-plane cliding friction, so reduced friction force to the influence of taking off required power takes place to squeeze.

The specific embodiment
As shown in Figure 3, roller squeezes and takes off device, comprise adjustment nut 1, bearing cap shim 2, dish spring 3, squeeze and take off post 4, contact seat 5, locking iron 6, roller 7, roller 7 takes off between post 4 and the locking iron 6 crowded, locking iron is provided with the groove 8 that can embed roller, squeezes to take off the post bottom and be provided with the slot rolling 9 that can insert roller.
Shown in Fig. 4,5,6, the crowded slot rolling 9 that takes off the setting of post bottom is under shed, and described opening makes roller pack into and to guarantee from slot rolling 9 and do not come off less than the diameter of roller.Squeeze the end take off post bottom slot rolling 9 and be provided with the boss 10 that the restriction roller moves, can limit roller and can not continue to move forward, the afterbody of roller also has a screw to withstand slot rolling can not be moved backward.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limit practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
