Description
Technical field
The utility model belongs to the urban rail transit technology field, is specifically related to a kind of spring hole seat of steel rail vibration reduction fastener.
Background technology
In recent years, the development of the City Rail Transit Systems such as China's subway, light rail had effectively been alleviated the nervous situation of urban traffic rapidly.In these a series of construction, fastener system is absolutely necessary, and fastener is the connector that connects rail and sleeper, and the mode that fastener is withheld rail by spring realizes and being connected of rail, and the mode of fixing by the bolt railway spike realizes and being connected of sleeper; But because the spring installation is not in place, cause the frequent phenomenon of rupture of spring to become problem demanding prompt solution, this problem has not only increased the metro operation maintenance cost, is also a kind of potential potential safety hazard simultaneously; E type, PR etc. draw in the formula spring in installation process, and the workman uses the spring pull bar that spring is drawn in fastening elastic rod hole seat, uses sledgehammer to knock the spring tail end as more difficult installation spring and makes it enter the position; The spring hole seat of existing fastener is designed to via design, without constraint portions (as shown in Figure 1), exists wayward spring that the problem that whether puts in place is installed.Due to construction environment insufficient lights such as subways, great in constructing amount, the workman can't guarantee each uniformities of exerting oneself in the process that spring is installed, thereby can not guarantee to carry out in strict accordance with the spring installation specification, spring often can occur and install lack of standardization.
In the spring installation process, in case exerting oneself excessive, the workman can cause spring that tension is installed, the spring inner arc contacts fully with spring hole seat, existing spring hole seat mostly is the design of 2 * 45° angle with the spring contact site in addition, corner angle are comparatively sharp, spring was installed the position will be subject to the continuous cutting partly of spring hole seat corner angle, and spring is caused greatly fatigue damage, greatly reduces application life.In case and in installation process, the workman is firmly too small, spring was installed pine, can cause elastic-strip pressure not enough, not have the expection purpose spacing to rail, when causing train to pass through, rail displacement up and down is larger, may exceed spring bullet journey, equally also can cause the spring fracture.
The utility model content
For solving the problems of the technologies described above, the purpose of this utility model is the spring hole seat that proposes a kind of steel rail vibration reduction fastener.
The utility model adopts following technical scheme for completing above-mentioned purpose:
A kind of spring hole seat of steel rail vibration reduction fastener, the spring hole that has to install spring on the seat of described spring hole; Have in order to spacing spacing shoulder block is carried out in the installation of spring in the described spring hole of spring hole seat.
The described spacing shoulder block that is positioned at the spring hole is combined the spring hole that consists of blind hole structure with described spring hole.
The described spacing shoulder block that is positioned at the spring hole is positioned at the top in described spring hole, and the bottom in described spring hole is communicating structure.
The described spacing shoulder block that is positioned at the spring hole is positioned at the bottom in described spring hole, and the top in described spring hole is communicating structure.
Be positioned at the inner side end of described spacing shoulder block in spring hole to the distance of the spring insertion end outer face in spring hole, insert the end face of spring hole one end to the little 6 ~ 12mm of distance of spring inner arc face than spring.
Be positioned at the inner side end of described spacing shoulder block in spring hole to the distance of the spring insertion end outer face in spring hole, insert the end face of spring hole one end to the little 8 ~ 10mm of distance of spring inner arc face than spring.
Described spacing shoulder block and described spring hole seat are integrated moulding by casting.
Described spacing shoulder block and described spring hole seat are welded as a whole.
The spring hole seat of a kind of steel rail vibration reduction fastener that the utility model proposes, have spacing shoulder block in the spring hole of spring hole seat, the installation of spring is guaranteed, can be fast, the installation spring of guaranteeing both quality and quantity, make the installation level of every spring basically identical, and reach installation requirement; Avoided occurring causing the spring damaged or causing elastic-strip pressure not enough because spring is installed tension or pine was installed, do not had the phenomenon generation spacing to rail; Improve the application life of spring, and had easy for installation, characteristics efficiently.
