Abstract

The utility model provides a bolt-type reinforced concrete track tie; two sides of the track tie main body on a steel track base are respectively provided with a strip-type through hole that is used for mounting a bolt; the bottom of the strip-type through hole is provided with a rectangular groove that is larger than the length of the strip-type through hole, and the rectangular groove is arranged on the lower part of the track tie main body and is communicated with the strip-type through hole; the bolt is a T-shaped bolt, and one end of the bolt is used for being matched with a screw cap to connecting with a screw rod, and the other end of the bolt is a T-shaped end; the size of the T-shaped end is equal to the size of the strip-type through hole. The track tie has the advantages of skillful construction, simple structure and reasonable design. Since strip-type holes and rectangular grooves are arranged on the track tie to be matched with the T-shaped bolt, the wearing part bolt can be replaced from the upper part of the track tie, thereby being convenient to replace the bolt, and saving the time and the labor power.

Description

The bolt type reinforced concrete sleeper

Technical field

The utility model relates to the improvement technology of colliery railway with sleeper, is specifically related to a kind of bolt type reinforced concrete sleeper that is convenient for changing bolt.

Background technology

As everyone knows, the colliery railroad track is the key of colliery material transportation.At present, most of collieries railroad track mainly adopts concrete sleeper, and it mainly is made of with the connector that is connected track (bolt) the sleeper body.In the prior art, the connector (bolt) that connects track and sleeper body normally is embedded in the sleeper body, perhaps connector (bolt) is upwards worn from the bottom of sleeper body, install rail after, use again that briquetting and nut and connector (bolt) are fastening to be connected as a single entity rail and sleeper.But because mine car operation and vibrations for a long time very easily cause the damage of connector bolt silk tooth, therefore, the connector bolt belongs to consumable accessory, needs often to change.If adopt the sleeper of pre-embedded bolt, then need to change whole sleeper, must cause great waste, and it is longer to change the sleeper time, influences conevying efficiency; And the structure that adopts bolt upwards to wear from sleeper body bottom need be employed bigger labour sleeper is lifted can to install and change bolt, obviously has inconvenient part, uses this structure also very easily to damage sleeper simultaneously, influences the application life of tie.

The utility model content

At the prior art above shortcomings, the purpose of this utility model provides a kind of bolt simple in structure, conveniently replaced, and can prolong the sleeper bolt type reinforced concrete sleeper in application life.

The purpose of this utility model is achieved in that the bolt type reinforced concrete sleeper, comprises sleeper body, bolt and buckle; The both sides that it is characterized in that being positioned at rail bed on the sleeper body vertically are provided for the stripe shape through hole of erection bolt respectively, the stripe shape via bottoms is provided with the rectangular recess greater than stripe shape through hole length, and rectangular recess is located at the bottom of sleeper body and is communicated with the stripe shape through hole; Described bolt is a T type bolt, and the one end is to be used for the screw mandrel that is connected with nut, and the other end is T type termination; The size of T type termination and the sizableness of described stripe shape through hole.

Also be preset with backing metal in the rectangular recess of described sleeper body bottom; Backing metal is laminar, and the middle part is provided with and identical stripe shape through hole relative with the tie body, and both sides, the long limit of stripe shape through hole are respectively equipped with projection in the same way.

Compared to existing technology, the utlity model has following advantage:

1, be skillfully constructed, simple in structure.Because design bar hole and rectangular recess and the pairing of T type bolt on sleeper, so just can be from the top replacing consumable accessory bolt of sleeper, change just very convenient, and time saving and energy saving.

2, reasonable in design.Owing in the rectangular recess of sleeper bottom, also be provided with backing metal, the root of T type bolt is matched with it, can prolong the application life of sleeper greatly.

The specific embodiment

As shown in Figure 1, a kind of bolt type reinforced concrete sleeper, mainly bolt 2 and the buckle 3 by sleeper body 1, connection rail 4 constitutes; The both sides that are positioned at rail 4 bases on sleeper body 1 vertically are provided for the stripe shape through hole 1.1 of erection bolt 2 respectively, stripe shape through hole 1.1 bottoms are provided with the rectangular recess 1.2 greater than stripe shape through hole 1.1 length (limit), and rectangular recess 1.2 is located at the bottom of sleeper body 1 and is communicated with stripe shape through hole 1.1.Referring to Fig. 2 and Fig. 3, bolt 2 is a T type bolt, and the one end is to be used for the screw mandrel 2.1 that is connected with nut 6, and the other end is T type termination 2.2; The size of T type termination 2.2 and the sizableness of the stripe shape through hole 1.1 on the sleeper body 1, and can pass described stripe shape through hole.After passing the stripe shape through hole and rotate an angle of 90 degrees in rectangular recess 1.2, the T type termination 2.2 of bolt 2 stops the location with end face that stripe shape through hole 1.1 is transferred to rectangular recess 1.2 mutually, the upper end of bolt 2 is put on buckle 3 and is connected with nut 6, rail 4 can be fixed on the sleeper body 1.Among the figure, the 7th, resilient sleeper-bearing.

Mine car uses the utility model, owing to after operation and vibrations cause 2 teeth of bolt to damage for a long time, can be changed bolt 2 easily.Promptly only need loosen nut 6 to take off the buckle 3 of rail 4 base both sides, again T type bolt is rotated an angle of 90 degrees, make the T type termination 2.2 of bolt 2 relative, so just bolt 2 directly can be taken out from the top of sleeper with stripe shape through hole 1.1, changed bolt very easily, and time saving and energy saving.In addition, directly act on the concrete sleeper for fear of the T type termination 2.2 of T type bolt 2, and influence application life of concrete sleeper, also default (burying) has backing metal 5 in the rectangular recess 1.2 of sleeper bottom; Referring to Fig. 4 and Fig. 5, backing metal 5 is laminar, and its middle part is provided with and identical stripe shape through hole 5.1 relative with tie, is respectively equipped with on the length sides of stripe shape through hole 5.1 to be used to prevent T type bolt 2 that rotate, projections in the same way 5.2; Owing to use the backing metal 5 and the root of T type bolt to match, can effectively prolong the application life of concrete sleeper.

Referring to Fig. 6 and Fig. 7, buckle 3 central authorities are provided with the circular hole 3.1 that matches with T type bolt 2 screw mandrels 2.1, and buckle 3 is provided with the convex shoulder 3.2 that is used to compress the rail seat.
