Abstract
The invention discloses a compensatory self-locking steel rail elastic fastener comprising a spring and an embedded iron seat, wherein a self-locking block is arranged between the spring and the embedded iron seat, and the combined parts of the spring and the self-locking block are of lock catch structures matched with each other. By adding the low-cost self-locking block, the compensatory self-locking steel rail elastic fastener can better solve the problems of in-place installation, displacement control and height adjustment of the spring; and the compensatory self-locking steel rail elastic fastener can be used for conveniently reforming and updating the same type of fasteners without the functions of self locking and height adjustment so that the traditional fastener system has better comprehensive fastening performance, and the compensatory self-locking steel rail elastic fastener is greatly convenient for the maintenance of the fastener system in daily use and improves the safety of the fastener system.
Description
Technical field
The present invention relates to a kind of railway track fastener, especially relate to a kind of compensatory self-locking steel rail elastic fastener.
Background technology
Domestic existing a large amount of III type elastic bar fastener, this fastener is made up of spring (III type), Insulation rail distance keeper, rubber mat plate and the preburied iron base that is positioned prestressed concrete non-shoulder pillow, its advantage is a non-bolt, maintenance is little, shortcoming: the one, spring takes place situation not in place is installed in spring installation requirement height easily; The 2nd, making the rear section spring firm by ramming at big base has offset phenomena, and the 3rd, spring does not have vertically heightens function, withholds in case generation subgrade settlement just can't guarantee the safety of fastener.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art, the invention provides a kind of compensatory self-locking steel rail elastic fastener, compensation by between spring and preburied iron base, increasing by one from snap close piece, solved the problems referred to above that exist in the background technology effectively.
The technical solution adopted for the present invention to solve the technical problems is: a kind of compensatory self-locking steel rail elastic fastener comprises spring and preburied iron base; Between described spring and preburied iron base, be provided with self-locking block, adopt the buckle structure that cooperatively interacts at described spring and self-locking block joint portion.
Described buckle structure is concavo-convex buckle structure, be included in be provided with on the described spring along being of its axis step-like spill fore shaft, in described self-locking block, be provided with along the step-like male locks platform that matches with the spill fore shaft that is provided with on the spring of being of its axis.
Compared with prior art, good effect of the present invention is: by adding a self-locking block cheaply, can solve the displacement that is in place, controls spring such as spring, the problem of heightening of solution spring preferably; And by the present invention, the fastener of the same type of can be easily function being heightened in no self-locking carries out transformation and upgrade, in the past fastener system is had better withhold combination property, be very easy to this maintenance of type fastener system in daily use, and the safety that has improved fastener system.Be in particular in:
1) increased self-locking block, spring is when mounted as long as the snap close (spill fore shaft) of spring arrives self-locking block snap close place (male locks platform), and the two is engaged to illustrate that promptly spring is in place;
2) self-locking block has limited the displacement of spring;
3) can realize vertically heightening of fastener by changing the different-thickness self-locking block during sleeper generation sedimentation, guarantee fastener safety.
4) can upgrade to fastener system of the same type, to solve the problem of no self-lock ability and subgrade settlement.
Description of drawings
The present invention will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a sectional drawing of the present invention;
Fig. 2 is a vertical view of the present invention;
Fig. 3 is the enlarged drawing that spring of the present invention and self-locking block are used;
Fig. 4 is the partial enlarged drawing of spring of the present invention;
Fig. 5 is a self-locking block enlarged drawing of the present invention.
The specific embodiment
A kind of compensatory self-locking steel rail elastic fastener, comprising: rail 1, spring 2, preburied iron base 3, self-locking block 4, rubber mat plate 5, Insulation rail distance keeper 6, spill fore shaft 7, male locks platform 8 to shown in Figure 5 as Fig. 1.
As shown in Figure 1, preburied iron base 3 directly is anchored in the sleeper, spring 2 is plugged in the preburied iron base, and form buckle press by the distortion that its toe-end is withheld face and withhold rail 1, between spring 2 and preburied iron base 3, be provided with self-locking and heightened the self-locking block 4 of effect, between rail and sleeper, be provided with the rubber mat plate 5 of cushioning effect; As shown in Figure 2, withhold at rail and spring and be provided with the Insulation rail distance keeper 6 that is used for the horizontal gauge of adjusting and plays insulating effect between the face.
For the ease of the installation of spring, and the displacement of restriction spring, the buckle structure that cooperatively interacts can be adopted at spring and self-locking block joint portion.Wherein the simplest suitable buckle structure is concavo-convex buckle structure, as Fig. 3, Fig. 4, shown in Figure 5, adopt the concavo-convex buckle structure that cooperatively interacts at spring and self-locking block joint portion, promptly spring is provided with along step-like spill fore shaft 7 of being of its axis, in self-locking block, be provided with along step-like male locks platform 8 of being of its axis, make spill fore shaft 7 and male locks platform 8 engaged when spring is installed, reach the function of fastener self-locking.
Claims (2)
1. a compensatory self-locking steel rail elastic fastener comprises spring and preburied iron base; It is characterized in that: between described spring and preburied iron base, be provided with self-locking block, adopt the buckle structure that cooperatively interacts at described spring and self-locking block joint portion.
2. compensatory self-locking steel rail elastic fastener according to claim 1, it is characterized in that: described buckle structure is concavo-convex buckle structure, be included in be provided with on the described spring along being of its axis step-like spill fore shaft, in described self-locking block, be provided with along the step-like male locks platform that matches with the spill fore shaft that is provided with on the spring of being of its axis.
