Problems solved by technology

As a result, the hexagonal head of the clip bolt 11 must be oriented towards the fastening plate 12, so that when the clip bolt is tightened it must be retightened by up to 60° anyway, due to the thread strength of, for example, M20 (and the pitch of the connection) which again requires very large forces which may adversely act on the connected parts

Embodiment Construction

[0014] figure 2 in relation to figure 1 The enlarged illustration shows a schematic view of the switch rail 4 with the locking seat 7 fastened thereto. The head 13 of the locking seat bolt 11 fixes the locking seat 7 with a pressure acting vertically on the switch rail 4 . The head 13 has a hexagonal shape. The fastening plate 12 designed as a spring plate has holes corresponding in area to a hexagon. If the fastening plate 12 is now pushed onto the head 13 , it bends upwards and snaps into place on the head 13 when the holes fit perfectly into the head 13 . Therefore, the head 13 must be precisely oriented towards the hole in the fixing plate 12 .

[0015] image 3 a now shows the figure 2 The situation with the spring pad 14 put under the head 13 of the locking seat bolt 11 according to the present invention (detailed drawing see image 3 b). As a result, the locking seat screw 11 can be fixed within a small torque range. At the same time, this solution allows fur...

Abstract

Ratchet pawl lock with lock clip bolt. The invention relates to a locking seat (5) for a turnout adjustment device, having a locking seat bolt (11) passing through the rail bottom of a switch rail (4) and a locking seat bolt (11) arranged between the rail bottom and the locking seat bolt (11) Spring washers (14) between bolt heads (13).

Description

technical field [0001] The invention relates to a ratchet pawl lock (Klinkenverschluss) with a locking clip bolt (Verschlussklammerschraube). Background technique [0002] Furthermore, ratchet pawl locks are also used for the adjustment of railway switches. The construction of this ratchet pawl lock is described in great detail in European patent document EP 0 624 508 A1. The pawl lock described there for a switch rail of a railway switch comprises a lock pawl actuatable by means of a slide bar and a lock element, wherein the lock pawl is pivotably arranged in a locking seat and the switch rail is fixed on On the upper end of the locking seat (Verschlusslager). [0003] The locking seat is used in railway switches to pull the tip of the switch rail onto the adjacent rail side and fix it there. In this case, the tongue rail is slidably guided on the sleeper over a certain length. In this case, one end merges into a rail section which is fixedly connected to the sleeper, w...
