Abstract

The utility model relates to a multifunctional sliding-bed plate used for supporting a pointed track of a switch, and solves the problems that when the pointed track moves on the sliding-bed plate, the friction resistance is large, and the pointed track can not be reliably positioned and can move and skip on the sliding-bed plate. The utility model can reduce the resistance and solve the skipping and moving problem of the pointed track by adding a pulley assembly composed of a spacing bracket and a friction reducing wheel and an anti-skipping wheel which are installed on the spacing bracket. The pulley assembly is installed on an antiskid stage of which the center is provided with a groove. Two strip-shaped elastic strips are used as buckles on the inner side of a base track. The front end of the elastic strip is arranged on the bottom of the base track. The middle section of the elastic strip is clamped under two wings of a wing-shaped sliding-bed stage respectively. The tail part is provided with a cushion block which is arranged in a cushion plate through small grooves on the cushion plate so as to increase the buckling and pressing force and the elasticity of the elastic strips.

Description

Multi-functional slide plate

The utility model relates to the turnout baseplate of the supporting tongue that a kind of rail track track switch uses.

Traditional turnout baseplate, because tongue motion on its sliding bed platform is subjected to sliding friction, switch convert resistance is big, and speed-raising back tongue is by in the past interlock, after changing transfer into, scold from tongue only to rely on the outer locking device at towing point place to keep its position, can not reliably locate, the tongue generation is beated and is moved, and influences the equipment operate as normal.

The purpose of this utility model provides a kind of frictional resistance that both can reduce tongue and sliding bed platform, can prevent that again tongue from beating to solve reliable orientation problem turnout baseplate.

The technical solution of the utility model is as follows: it is made up of pulley combination and the backing plate sliding the bed platform, be installed on the sliding bed platform that the both sides that have rectangular slot along central axis have both wings.Pulley combination is by limiting bracket, rack-mount anti-attrition wheel and the anti-jump composition of taking turns, the front end of limiting bracket inserts in the groove of sliding the bed platform and blocks, tail end is fixed by bolts on the backing plate, the anti-attrition wheel that two diameters do not wait is installed in the middle part of support, diameter near tongue one side is less, so that tongue moves, the anti-jump tail end that is installed in support of taking turns upwarps portion, both being beneficial to tongue slides, can prevent that again tongue from beating, in addition, because the tail end perk of support, can prevent to move forward after tongue from putting in place, because sliding bed platform center grooved, the fastener of withholding stock rail that is contained on the slide plate is made up of two stripe shape springs and cushion block, and the front end of spring is pressed on the flange of rail, the middle part is stuck under the both wings of sliding bed platform, have sulculus on backing plate, cushion block is bumped in the groove, the afterbody of spring places on the cushion block, to keep the elastic force of spring, prevent the spring play simultaneously.

In track switch when conversion,, scolding leaves the right or normal track slides into major diameter anti-attrition wheel by minor diameter anti-attrition wheel, and after moving into place, the anti-jump wheel pushed down the tongue flange of rail, prevents that it from beating, and limits it and move laterally; Close obedient tongue slides into minor diameter anti-attrition wheel by major diameter anti-attrition wheel, and after close card put in place, the tongue flange of rail was thrown off the anti-attrition wheel, drops on the slide unit.

The utility model is located on the adjacent sleeper of track switch towing point, and each towing point is established a pair of.Because tongue changes rolling friction with a sliding bed platform into by sliding friction, has reduced friction, in addition, limiting bracket can limit that scolding leaves the right or normal track moves laterally, has avoided the malfunction of switch indication, and anti-jump on it taken turns and can be prevented that tongue from beating.

Fig. 1 is a lateral view of the present utility model

Fig. 2 is a vertical view of the present utility model

Among Fig. 1, multi-functional slide plate is made up of sliding bed platform 6, backing plate 7 and pulley combination.Pulley combination by limiting bracket 2, be installed in the anti-attrition wheel 5 that two diameters on the support 2 do not wait and be installed in support 2 tail ends top anti-jumply take turns 1 and form, the anti-attrition wheel diameter of close tongue 8 one sides is less.

Among Fig. 2, the sliding bed platform 6 that is cast with both wings has rectangular slot along central axis, and the front end of support 2 inserts in the groove of sliding bed platform 2, and tail end is fixed by bolts on the backing plate 7.

Because the center of sliding bed platform 6 has groove, the fastener rail inboard of withholding stock rail changes into by two stripe shape springs 4 and cushion block 3 to be formed, the front end of spring 4 is pressed on the flange of rail, the middle part is pressed under the both wings of sliding bed platform 6, open a sulculus on the backing plate 7, cushion block 3 is placed wherein, and the afterbody of spring is placed on the cushion block 3, to increase the elasticity and the buckle press of spring.
