Abstract

The invention discloses a steel rail insulation connector glue joint protection device. The steel rail insulation connector glue joint protection device comprises two steel rail insulation connectors.A glue joint gap is arranged between the two steel rail insulation connectors. An adhesive is arranged in the glue joint gap and is wrapped by a heat preservation layer. The outline of the heat preservation layer is in an isosceles trapezoid shape. An outer shell is arranged outside the heat preservation layer. The inner wall of the outer shell is attached to the outer surface of the heat preservation layer. The two side faces of the outer shell are slope faces. The steel rail insulation connector glue joint protection device can overcome the defects in the prior art, the structure is simpleand reasonable, enough protection can be provided for the adhesive connecting the steel rail insulation connectors at the two ends, the situation that when the temperature greatly changes, performanceof the adhesive fluctuates, and consequently the glue joint quality is poor is avoided, the situation that the adhesive is in an exposed state for a long term is avoided as well, and the service lifeis prolonged.

Description

technical field [0001] The invention relates to the field of track parts, in particular to a glued protection device for rail insulating joints. Background technique [0002] Rail insulation joints are currently fixed by glue joints. When the temperature difference is large, the performance of the glue fluctuates greatly, resulting in poor quality of glue joints. In addition, the service life of glue that has been exposed for a long time is short. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies, the present invention provides a rail insulation joint glue joint protection device, which includes two sections of rail insulation joints, a glue joint is provided between the two sections of rail insulation joints, and glue joints are provided in the joints. agent, the adhesive is coated with a thermal insulation layer, the outer contour of the thermal insulation layer is isosceles trapezoidal, the thermal insulation layer is provided with...
