Abstract
The utility model relates to a fastener-type steel-rail loose preventing device, which comprises a steel rail, a sleeper, a bolt, a spike, a fastener, a spring, an arc stop seat and an iron cushion plate. The bolt which is arranged on the fastener is used to make a rail bottom and the iron cushion plate connected together. The arc stop seat is arranged on the iron cushion plate. The fastener is composed of a press tongue, a front stop shoulder, a stop groove of an elastic strip and an arc stop shoulder. The arc stop shoulder and the arc stop seat are attached. The elastic strip is positioned by the stop groove of an elastic strip. The spike is fixed between the iron cushion plate and the sleeper. The utility model has the characteristics of no looseness, no loss, less damage, less maintenance and no failure.
Description
The utility model is a kind of anti-creep device that is used for preventing on the wooden railroad crosstie circuit rail creeping, and sleeper track switch the going up that is specially adapted to various models used.
The anticreeper that uses on the existing railway is two kinds of string Xiao's formula and bolt types.Its disadvantage be easily become flexible, easily lose, cracky, bring many difficulties for normal maintenance.
The purpose of this utility model is a kind of fastener type rail anchor that does not become flexible, does not lose, lacks damage, few maintenance and do not lose efficacy of design.
The purpose of this utility model is achieved in that the fastener type rail anchor, comprise rail, sleeper, bolt, railway spike, it also comprises fastener, spring, arc block seat and iron chair, spring on the described fastener links together the flange of rail and described iron chair by bolt, the arc block seat is arranged on the described iron chair, described fastener is by pressing tongue, preceding shoulder block, spring retaining groove and arc shoulder block are formed, described arc shoulder block and described arc block seat fit, described spring is located by described spring retaining groove, fixes with railway spike between described iron chair and the described sleeper.
The utlity model has following advantage: 1) do not become flexible, do not lose efficacy, do not lose, lack and damage, do not need maintenance basically; 2) this device does not influence any regular link maintenance activity, and anti-creep is effective, and the anti-creep resistance is stable, lasting.
Fig. 1 is the assembly drawing of the utility model fastener type rail anchor;
Fig. 2 is that the master of the utility model fastener looks sectional view;
Fig. 3 is the vertical view of the utility model fastener;
Fig. 4 is the vertical view of the utility model iron chair;
Fig. 5 is Fig. 4 A-A sectional view.
Describe architectural feature of the present utility model in detail below in conjunction with accompanying drawing.
The utility model mainly is made up of fastener 1, spring 2, plain cushion 3, nut 4, rectangular dormant bolt 5, arc block seat 6, iron chair 7, screw spike 8, the little rubber cushion 9 of friction, the big rubber cushion 10 of friction.Fastener 1 is by pressing tongue 13, preceding shoulder block 14, bolt hole 15, spring retaining groove 16, arc shoulder block 17 to form.Iron chair 7 is made up of screw spike hole 18, rectangular dormant bolt hole 19, positive stop 20.Press tongue 13 with rubbing little rubber cushion 9 clinchings on the flange of rail 11, preceding shoulder block 14 joins with the distolateral of the flange of rail 11 by the little rubber cushion 9 that rubs, and arc shoulder block 17 fits with arc block seat 6.Preceding shoulder block 14 plays fixed track apart from effect jointly with arc shoulder block 17, arc block seat 6.Spring 2 on the fastener 1 links together the flange of rail 11 and iron chair 7 by plain cushion 3, nut 4, rectangular dormant bolt 5, and tightening nuts 4 can increase the anti-creep resistance of this device.Spring 2 is made it and can not be moved by the front and back string by spring retaining groove 16 location.Fixing between iron chair 7 and the sleeper 12 with screw spike 8, make the flange of rail 11, iron chair 7 form an integral body with sleeper 12, stop the lateral force of creeping of rail and train with this.
Installation of the present utility model is also very convenient.60 kilograms of sleeper buckle type track switches can directly be taken off former buckle, change fastener 1, and the little rubber cushion 9 of friction on fastener 1 and 11 pads of the flange of rail (can cancel the big rubber cushion 10 of friction this moment) is installed spring 2 on fastener 1, tighten and get final product with plain cushion 3, nut 4 again.Because the screw spike of this moment near the arc block seat, is not conflicted mutually in order to make spring 2 and original thread railway spike, can suitably increase the height of arc shoulder block 17.When track switch below 50 kilograms or sleeper circuit are installed, should earlier former iron chair be withdrawn from, press the different choice iron chair 7 of rail type, put on rectangular dormant bolt 5, iron chair 7 is installed in the flange of rail 11 times, the big rubber cushion 10 of friction on 11 pads of the iron chair 7 and the flange of rail, again with the same method fastener for installing 1, the little rubber cushion 9 that rubs, spring 2, plain cushion 3, tightening nuts 4 more at last.12 on iron chair 7 and sleeper are fixing with screw spike 8.
The adjustment of gauge can realize by the little rubber cushion 9 of friction of selecting different-thickness or the fastener 1 of changing different model.Fastener for installing formula rail anchor needn't be provided with in pairs, also needn't in a row lock, and can determine to install quantity according to the amount of creeping of sub-thread rail.Particularly 60 kilograms of buckle type track switches can all be installed in this anticreeper the straight strand of basic trackside of easily creeping and get final product.According to searching relevant data and practical application proves: install the anti-creep effect that 10 these anticreepers of cover can be equivalent to 10 pairs of string Xiao formula anticreepers.
