Abstract
Disclosed is a dust blocking shade. The dust blocking shade is composed of two shade bodies (1) and an elastic clamping piece (2) in a connecting mode, wherein the two shade bodies are symmetrically arranged in parallel, the lower ends of the two shade bodies are open, the elastic clamping piece is used for connecting the shade bodies, and a bayonet (3) which can be clamped into a steel rail top is formed in the middle of the elastic clamping piece (2). The dust blocking shade solves the protection problem of a sleeper and a buckling piece in the process of track bed concrete pouring, prevents the sleeper and the buckling piece from being damaged, and meanwhile improves the track bed concrete pouring efficiency.
Description
Technical field
The utility model belongs to the railway casting technical field, is specifically related to a kind of ash retaining cover.
Background technology
In the railway engineering installation process, fastener outward appearance and performance, sleeper outward appearance usually can appear by the phenomenon of concrete destruction when after sleeper and the fastener installation that matches, railway roadbed being carried out concreting.Based on this, people usually adopt plastic sheeting that it is protected.But poor due to plastic sheeting light weight, weatherability, cause can't coordinating with rail, sleeper without good size etc., cause fastener, sleeper protection bad and impaired.
The utility model content
The technical problem that the utility model solves: a kind of ash retaining cover is provided, solves sleeper and the protection question of fastener in concreting process, prevent that sleeper and fastener are impaired, improve simultaneously the efficient that railway roadbed carries out concreting.
Technical solution of the present utility model: a kind of ash retaining cover be formed by connecting with the elastic card that is connected two cover bodies by the cover body that two symmetries are arranged side by side and the lower end is uncovered, and the middle part of elastic card has the bayonet socket that can snap in rail top of steel rail.
The upper surface that the lower end of described cover body is fastened on sleeper is enclosed in fastener in cover body.
Described cover body adopts the engineering plastics one-shot forming.
The advantage that the utlity model has and effect:
1, the utility model is simple in structure, cost is low, and is reusable, long service life, and coordinate desirable, easy to install with rail, sleeper, fastener etc.
2, the utlity model has some strength and good impact resistance, weatherability, chemical resistance, can effectively prevent from when railway roadbed from carrying out concreting the destruction of sleeper and fastener has been improved the efficient that railway roadbed carries out concreting simultaneously.

Fig. 3 is the utility model structure left view.
The specific embodiment
Below in conjunction with accompanying drawing 1,2,3, a kind of embodiment of the present utility model is described.
A kind of ash retaining cover be formed by connecting with the elastic card 2 that is connected two cover bodies 1 by the cover body 1 that two symmetries are arranged side by side and the lower end is uncovered, and the middle part of elastic card 2 has the bayonet socket 3 that can snap in rail top of steel rail.Described.Described cover body 1 adopts the engineering plastics one-shot forming.
The utility model is stuck on rail top of steel rail by elastic card when using, and the upper surface that the lower end of cover body 1 is fastened on sleeper is enclosed in fastener in cover body 1, guarantees that concrete can not infiltrate contacting piece and produce destruction.And can adjust the dust-blocking cover product size according to the sleeper size.
Above-described embodiment is preferred embodiment of the present utility model, is not to limit the utility model practical range, thus all equivalent variations of being done with the described content of the utility model claim, within all should being included in the utility model claim scope.
Claims (3)
1. ash retaining cover, it is characterized in that: described ash retaining cover is formed by connecting with the elastic card (2) that is connected two cover bodies (1) by the cover body (1) that two symmetries are arranged side by side and the lower end is uncovered, and the middle part of elastic card (2) has the bayonet socket (3) that can snap in rail top of steel rail.
