Abstract
The utility model discloses a fastening structure of a railway concrete sleeper spike. The lower end of a spike is changed and casted as an elliptical taper body and is covered by an elliptical taper sleeve, an integrated body which matches the elliptical taper body is put into an elliptical taper hole which is meshed and consistent with the elliptical taper body through the lower end of a sleeper, and a bolt part is exposed, is covered by a flat gasket and is screwed with a thin nut, the spike is fixed at the sleeper, then all fasteners and parts are mounted, and a top nut is screwed down, so the spike can be fastened firm inside a concrete elliptical taper hole. The fastening structure of the railway concrete sleeper spike can replace sulfur anchoring which has the disadvantages of causing environmental pollution, complex construction, being not capable of changing and recycling, wasting resource.
Description
Described technical field
This practicality newly relates to a kind of fastening structure of railway concrete sleeper railway spike.
Background technology
The railway concrete sleeper is in order to still to adopt sulfur cement mortar anchorage agent anchoring with the method for bolton within its circular hole at present, and the sulfur cement mortar anchorage railway spike will boil sulphur, environment is polluted, and the harm workers ' health, construction is complicated loaded down with trivial details.Owing to adopt the disposable utilization of the fixed anchoring of this kind, when in case railway spike makes situations such as railway spike becomes flexible because of thread damage, corrosion and sulfur cement mortar anchorage lost efficacy, whole sleepers is also scrapped, together abandon together with four railway spikes, can't regain again and utilize, cause the multiple loss of its coherent domestic animal, so far seek a kind of economical and practical railway spike fastening means is the difficult problem that the expectation of railway department solves always.
The utility model content
The utility model provides a kind of simple in structure, installing/dismounting and changes concrete sleeper railway spike fastening structure easily.This structure is at existing railway spike, nut, elastic bar fastener, to be improved with the railway spike and the sleeper hole that are anchored in the sleeper circular hole on the basis of shell fragment etc., railway spike within it is cast as has the big concentric ellipticity body of top handle, make conical plastics sleeve pipe that an endoporus is meshed with it again and it is enclosed within on the railway spike of elliptic cone body, four circular holes of concrete sleeper are changed system into and the together big consistent oval bellmouth of shape of the railway spike that puts plastic bushing, so far the railway spike that only needs to put plastic bushing penetrates from the following hole of sleeper, the bolt of its upper end is partly exposed, the Dai Yiyuan plain cushion is fixed with thinner nut thereon, in order to avoid railway spike falls in the sleeper hole, all supporting elastic bar fasteners, spring, shell fragments etc. are enclosed within the nut and it is tightened screwed on the bolt and get final product.Because the sleeper hole all becomes the elliptic cone shape with railway spike within it, can not form the phenomenon of working day and night when firmly tightening, and in the oval bellmouth that is fastened on sleeper that can it is firm, thereby sulfur cement mortar anchorage replaced.And, no longer abandon other all intact sleeper and railway spikes because of a bolts damages to later dismounting and change or the good condition of recycling creation, its benefit is considerable.
Advantage of the present utility model just is: simple structure, easy construction, installation save time, dismantle flexibly, be beneficial to replacings, can realize utilizing again and the effect of useless railway spike recovery.

Specific embodiments
As Fig. 1, shown in Figure 13, concrete implementation step is as follows:
Oval taper railway spike (1) among Fig. 1 is penetrated from plastic bushing (2) lower end, in the lump again from the lower end of concrete sleeper penetrate with the supporting consistent oval bellmouth (3) of its engagement in, make bolt all be exposed at top, cover upper gasket (4), the thin nut 5 of screwing on causes railway spike down not come off.Installing and loading onto packing ring (6) nut (7) of screwing on behind the various fastener spare and accessory parts is the finishing device overall process.
Owing to penetrate the railway spike that is with plastic bushing in the sleeper hole, all be complete supporting tight engagement be the elliptic cone physique structure, therefore firmly tightening the top nut when fastening, bolt has enough anti-rotation abilities, when fastening, make and move on the bolt also from the sleeper hole, to deviate from, and can be firm with its fastening being squeezed within the concrete sleeper hole, and can help evenly disperseing to make to add the expansive force of splashing that acts in the sleeper hole, prolong its application life.
Need its railway spike of dismounting and change very convenient, as long as nut and accessory take down, slightly firmly hammering bolt top just can be with its whole taking-ups.
Claims (3)
1. the fastening structure of a railway concrete sleeper railway spike, by oval taper railway spike, oval conical plastics sleeve pipe, the oval bellmouth of sleeper, compositions such as nut and plain washer is characterized in that: the top of oval taper railway spike is the body of bolt, the bottom is the elliptic cone body.
2. the fastening structure of railway concrete sleeper railway spike according to claim 1 is characterized in that: plastic bushing is the elliptic cone shape, and its internal diameter is identical with oval taper railway spike bottom, and external diameter is consistent with the oval bellmouth epimere of sleeper.
3. the fastening structure of railway concrete sleeper railway spike according to claim 1, it is characterized in that: the sleeper hole be prefabricated into oval bellmouth make the oval taper railway spike that is through wherein and oval conical plastics thimble joint at the assembly of one when fastening, prevent to work day and night and railway spike is deviate from from the sleeper hole, and evenly its expansive force of splashing that acts in the sleeper hole is distributed on the entire contact surface.
