Description

Cementing insulating joint breaker Technical Field The utility model relates to the technical field of railway maintenance equipment, in particular to a cementing insulating joint breaker. Background The rail cementing insulating joint is a key structure for realizing the connection of a track circuit and machinery in a seamless line between areas, and is formed by compounding components such as standard rails, insulating clamping plates, insulating groove plates, insulating sleeves, insulating end plates, high-strength bolts and the like through a cementing process. The technical performance of the steel rail cementing insulating joint (TB/T2975-2018) is strictly in accordance with the standard of steel rail cementing insulating joints, and comprises the technical indexes of insulating resistance which is more than or equal to 10MΩ in a dry state and more than or equal to 1kΩ in a wet state, integral shear strength which is more than or equal to 4000kN, and the like. However, in the long-term service process, the adhesive layer is easily aged, cracked, insulated and invalid and the like under the influence of temperature stress, train dynamic load and environmental corrosion, so that the joint loses the electrical insulation function, and the safety of a track circuit and the running stability of a train are seriously threatened. And thus requires a re-arrangement after removal. For the problems, the prior art partially adopts hammering wedge iron stripping splints, the scheme is easy to cause the belly damage of the steel rail, the acting force direction is difficult to control, the risk of damaging the insulating end plate exists, the prior art also provides some technical schemes, such as CN202022645760.1 provides a quick adhesive frozen joint breaker, but the structure is complex, a hole is required to be dug at the bottom of the steel rail when the quick adhesive frozen joint breaker is used, the anti-jump fixing frame passes through the lower part of the steel rail, the operation is inconvenient, and a railway steel rail adhesive insulating joint splints stripper is disclosed in CN202123011344.7, and the bottom plate 5 also needs to pass through the lower part of the steel rail. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provide a cementing insulating joint breaker which is scientific in structure, simple and quick to operate and convenient to use. The utility model solves the technical problems by adopting the technical scheme that the cementing insulating joint breaker comprises a connecting plate, wherein a clamping device for clamping one section of steel rail and a pushing device for laterally pushing the other section of steel rail are arranged on the lower side of the connecting plate, the clamping device comprises two fixing seats respectively arranged on two sides of a rail head of the steel rail, a pressing rod for pressing the rail head on the side surface of the other fixing seat after penetrating through the fixing seats is arranged on the fixing seats positioned on the outer side, the pressing rod is in threaded connection with the fixing seats, the pushing device comprises a separated hydraulic jack and a supporting seat, the separated hydraulic jack comprises a piston rod for pushing the rail head of the other section of steel rail and a cylinder body, the piston rod is arranged in parallel with the pressing rod, the cylinder body is in abutting connection with the supporting seat, and the connecting plate is provided with an observation hole for aligning the insulating joint and the observation hole is positioned between the clamping device and the pushing device.
