　　1DK618-4-12 coal mine switchProduct Introduction:

　　Mining single switch is a basic setup that branches a track into two or more tracks, allowing locomotives and vehicles to switch from one track to another. The single switch number is represented by the frog number, and the intersection angle between the working sides of the switch center is called the frog angle. The residual tangent value of the frog angle is called the frog number. The commonly used turnouts are divided into single opening turnouts, symmetrical turnouts, compound crossover turnouts, and crossovers.

　　The model parameters of single turnout are classified by rail type as follows: 8 kg/m、12kg/m、15kg/m、18kg/m、22kg/m、24kg/m、30kg/m、38kg/m、43kg/m、50kg/m、60kg/m Switches used for steel rails. Divided by switch number, there are switches such as No. 2, No. 3, No. 4, No. 5, No. 6, No. 7, No. 8, No. 9, and No. 12.

　　IIDK618-4-12 coal mine switchComposition of

　　1. Switch: The switch consists of two basic rails, two switch rails, and a switch mechanism. Operating the switch mechanism can change the position of the switch rails, thereby determining the opening direction of the turnout.

　　2. Frog and guard rail: The frog and guard rail consist of a frog center, wing rail, and guard rail, ensuring the safe passage of wheels through the intersection of two tracks. Due to the existence of hazardous spaces, when locomotives and vehicles pass through hazardous spaces at the frog, the wheel flange may go wrong in the frog groove and cause derailment.

　　3. Connection part: The connection part consists of two straight rails and two curved rails, which are used to connect the switch, frog, and guard rail to form a complete set of turnouts.

　　Remedial measures for poor direction of single switch

　　1. Make sure the direction of the straight stock basic rail is correct and set the switch position.

　　2. Perform overall maintenance on the curve behind the switch and the 50m line before and after the switch. If there are poor on-site roadbed conditions, the switch needs to be extended

　　The maintenance distance before and after.

　　3. Make appropriate improvements to the homework method to ensure the correctness and smoothness of the track gauge and support gauge, and to prevent the generation of significant internal forces.

　　4. Strengthen the compaction work, ensure the quality of compaction work, and make appropriate adjustments according to the characteristics of the roadbed, track bed, and switch structure

　　Strong.

　　5. Bend the basic rail at the bending point and carry out the widening and decreasing of the track gauge.

　　6. Strengthen maintenance and repair of various parts to ensure that the role of various fasteners in fixing the position of the steel rail can be fully utilized.

　　Our company adheres to the principle of honesty and quality as the lifeblood of the enterprise. Through a scientific quality management system,DK618-4-12 coal mine switchConduct a comprehensive inspection of product quality to ensure its quality.Single switch switchAll indicators of the factory products meet or exceed national standards.
