Embodiment Construction

[0011] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0012] Such as figure 1 , 2 As shown, the present invention is a new type of rail insulation joint glue joint protection device, comprising two sections of rail insulation joint 1, a glue joint 2 is arranged between the two sections of rail insulation joint 1, and a glue joint 2 is provided in the glue joint 2. Adhesive 3, the adhesive 3 is coated with an insulation layer 4, a reinforcement layer 5 and an outer casing 6 in sequence, the insulation layer 4, the reinforcement layer 5 and the outer casing 6 are all C-shaped structures, and the insulation layer 4 is made of rigid polyurethane foam, the reinforcing layer 5 is made of No. 55 steel, and the lower e...

Abstract

The invention discloses a novel steel rail insulated joint gluing protection device which comprises two steel rail insulated joints. A gluing seam is formed between the two steel rail insulated joints. An adhesive is arranged in the gluing seam and sequentially coated with a heat preservation layer, a reinforcing layer and a shell body. Each of the heat preservation layer, the reinforcing layer and the shell body is of a C-shaped structure. The heat preservation layer is made of polyurethane rigid foam. The reinforcing layer is made of number 55 steel. The lower ends of the two side walls of the shell body retract inwards. The novel steel rail insulated joint gluing protection device can overcome the defects in the prior art, the structure is simple and reasonable, the adhesive connectingthe steel rail insulated joints at the two ends is fully protected, the situation that the performance of the adhesive fluctuates when the temperature changes and thus the gluing quality is poor is prevented, the adhesive is prevented from being in an exposed state for a long time, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of rail parts, in particular to a novel glued protection device for insulating joints of rails. 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 new type of rail insulation joint glue joint protection device, which includes two sections of rail insulation joints, a glue joint is arranged between the two sections of rail insulation joints, and glue joints are provided in the glue joints. Adhesive, the adhesive is coated with a thermal insulation layer, a reinforcement layer and an outer shell in sequence, the thermal insulation layer, the rein...
