Description

Technical Field

[0001] The utility model belongs to the technical field of slope brackets, and in particular relates to an adjustable metal slope bracket for railway signals. Background Art

[0002] The function of the rail lead wire is to connect the railway signal equipment and the rail. In high-speed railways, there is a height difference of about 60 cm between the rail and the outlet position of the railway signal equipment. The traditional method is to pile up cement slopes, but cement slopes have shortcomings such as cracking, powdering, corrosion resistance, and long construction and maintenance cycles. In order to solve the many problems of cement slopes, some existing high-speed railways use flat metal slope brackets. This bracket adopts a single-end adjustable method and is fixed between the rail and the signal equipment with chemical anchor bolts. The rail lead wire is fixed on the metal plate.

[0003] At present, the existing metal slope bracket has the following problems: 1. Due to the single-end adjustable method, the adjustable angle is very small; 2. The rail lead wire is directly fixed on the metal plate, which cannot play a protective role. (The high-speed rail runs very fast, and there is a phenomenon of ice and snow hitting the equipment) 3. The length cannot be adjusted and can only be customized according to the on-site conditions. For this reason, we propose an adjustable metal slope bracket for railway signals. Utility Model Content
