Problems solved by technology

However, they have a relatively complex structural design
Furthermore, such known devices have been shown to be susceptible to dust, sand and other environmental factors that arise in the vicinity of the rail system
This can lead to a malfunction or damage to the tongue lift, significantly reducing its operational reliability
As a result, the tongue lift has to be checked and maintained frequently
In addition, precautions such as wrapping around the tongue lift must be taken to prevent sand and stones from entering the tongue lift, which is laborious and time consuming

Embodiment Construction

[0029] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

[0030] figure 1 Shown is a schematic perspective view of the tongue lifting device 1 according to the first embodiment of the present invention. The tongue lifter 1 has a base body 8 in which two supporting bearing pins 22 and 24 are supported. Support bearing pins 22 and 24 are used to pivotally support the rollers 12 and 14 respectively in the tongue lifter 1 . Furthermore, the base body 8 has two fixing holes 8' and 8" to fix the tongue lifter 1 in its installed position.

[0031] figure 1 The first embodiment shown has two rollers 12 and 14 . It should be noted, however, that three or more rollers can be equipped, depending on the main requirements, such as that of the positioning range.

[0032] Between two adjacent rollers 12 and 14, a channel cover 10 is provided facing a first direction, wher...

Abstract

The invention relates to a device which is used to lift and displace the tongue blade (2) of a rail (6), comprising at least two rollers (12, 14) whereby the axes thereof are arranged in an essentially parallel manner in relation to a running rail (4), in order to displace the tongue blade (2) in a transversal manner in relation to the running rail (4), at least two support carrier pins (22, 24) which respectively support a roller (12, 14), and a base body (8) which supports the carrier pins (22, 24). The rollers (12, 14) have a projection which projects in at least one first direction in relation to the base body (8). The inventive device is characterised in that a covering (10) is arranged between at least two adjacent rollers and is oriented towards the first direction and at least partially covers a passage between the at least two adjacent rollers (12, 14).

Description

technical field [0001] The invention relates to a device for lifting and moving switch blades according to the preamble of claim 1 . Background technique [0002] The first mentioned device of this type, also known as tongue lift device, is very popular in the prior art, and it is easier to reverse the switch in the track system by moving the tongue blade. [0003] Thus, for example, EP0692570B1 discloses a tongue-lift device with two rollers pivotally supported on an adjustable tongue-lift platen preloaded by springs. These components have proven to be advantageous in practical applications. However, they have a relatively complex structural design. Furthermore, such known devices have been shown to be susceptible to dust, sand and other environmental factors that arise in the vicinity of the rail system. This can lead to a malfunction or damage to the tongue lift, which significantly reduces its operational reliability. As a result, frequent inspection and maintenance ...
