Abstract
The utility model relates to a fully-insulated joint fishplate for connecting railway tracks and belongs to the technical field of railway construction fittings. The fully-insulated joint fishplate is provided with a steel fishplate body with bolt holes and is characterized in that a plurality of anti-skidding protruding strips are arranged on the connecting surface of the steel fishplate body, which is in contact and connection with the railway tracks; and an insulated coating covers the surfaces of the fishplate body and the anti-skidding protruding strips. The utility model has the advantages of good integral insulation performance and anticorrosion performance, long service life, and simple and convenient field installation and construction, thereby being a substitute for the prior adhesive-bonding insulated fishplate.
Description
Technical field
The utility model relates to a kind of joint bar that railway track is used that connects.Belong to railway construction accessory technical field.
Background technology
Between two section of railway track rail, must adopt joint bar to connect.Electric locomotive travels and requires two sections connected rail will keep insulation.Present extensive employing be a kind of " splicing cleat insulator ", referring to " People's Republic of China's railroad industry standard " " speed per hour 250km/h and following railway track glued joint the insulating joint technical condition ", this splicing cleat insulator is to adopt the adhesive technology of heating, pressurize in factory, the clamping plate with certain insulating properties that clamping plate, troughing plate (or slotless shaped steel plate), insulation channel plate are made.With bolt joint bar is installed between the two section of railway track rail during use, utilizes insulation channel plate to realize that the insulation between the two rails connects.The shortcoming one of the existence of these clamping plate is that the vibrations when electric locomotive travels can cause the mutual displacement between rail and connecting cleat, easily produces and comes unstuck, and causes defective insulation; The 2nd, insulation channel plate is thinner, and meeting conducting clamping plate and rail make the class of insulation descend when the rainy water of the excessive situation of rainwater flows through narrow insulation channel plate edge; In addition, the steel of clamping plate part is exposed for a long time in air, and its anticorrosion needs are safeguarded specially.
The utility model content
The purpose of this utility model is the above-mentioned shortcoming that overcomes existing splicing cleat insulator, for the connection of railway track provides a kind of on-site maintenance and higher all insulation joint bar of reliability of insulating properties of need not.
This railway track all insulation joint bar has a steel clamping plate body that has bolt hole, the joint face with rail touches mutually that it is characterized in that steel clamping plate body is provided with some anti-skidding raised lines, is coated with an insulation coating in the surperficial integral body of described clamping plate body and anti-skidding raised line.The same with prior art, with bolt joint bar is installed between the two section of railway track rail during use, steel clamping plate body is the main body of bearing two sections rail tensile forces, shearing force, anti-skidding raised line plays increases mill sassafras power to prevent mutual displacement between rail and connecting cleat in order to avoid the wearing and tearing of insulation coating, and the insulation coating that is arranged on whole surface has guaranteed two sections insulation that are connected between the rail.
Compared with the aforementioned existing similar products, the advantage of this joint bar is to adopt the whole insulating layer that covers in surface, has realized the connector all insulation, and the glued layer that has solved traditional splicing cleat insulator easily comes unglued and comes off, the defective of insulating layer cracky has improved the reliability of insulation; Thoroughly stopped to cause the problem of clamping plate and the decline of rail insulation degree because of heavy rain.And antiseptic property is good, long service life.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.

The specific embodiment
Shown in Fig. 1～5, this railway track all insulation joint bar has a steel clamping plate body 1 that has bolt hole 3, the joint face with rail 5 touches mutually of steel clamping plate body 1 is provided with some anti-skidding raised lines 2, is coated with an insulation coating 4 in the surperficial integral body of described clamping plate body 1 and anti-skidding raised line 2.Insulation coating 4 can form by integral surface coating insulation plastic cement, also can adopt injection moulding or plating to mould and form.
