Description

Technical Field

[0001] The utility model relates to the technical field of support for a rail-bearing groove, and more specifically, to a support assembly for a rail-bearing groove of a ballastless track bed. Background Art

[0002] Level crossings and freight hub sections are the key parts in railway transportation and highway transportation. Ballastless track beds such as crossing slabs set rails in the groove through a rail-bearing groove, enabling motor vehicles, non-motor vehicles, and pedestrians to pass through the crossing or cross the railway at the hub section smoothly and quickly on the premise of ensuring safety. To improve the smoothness of vehicles passing through the crossing, the rail-bearing groove is usually designed as a dovetail-shaped closing structure to reduce the width of the rail-bearing groove. To prevent sundries such as stones from falling into the rail-bearing groove and affecting the train operation, and to protect spikes and fasteners, a support buckle plate is usually arranged in the rail-bearing groove.

[0003] In the prior art, as Figure 1 shown, trapezoidal groove-shaped support buckle plates are arranged on both sides of the rail in the rail-bearing groove. For relatively short crossings within twenty or thirty meters, after the rail is installed, the support buckle plates can be installed by threading them from one end of the rail-bearing groove to the other end. However, for crossings or freight hub sections with a large distance, since the distance of the rail-bearing groove is large, up to hundreds of meters or even thousands of meters, it is very difficult to install them by threading. And the existing support buckle plates are formed by stamping and bending a metal plate. One side abuts against both sides of the rail, and the other side abuts against the inner wall of the rail-bearing groove, being in close contact with metal parts such as rail fasteners, angle irons, and steel bars in the crossing slab or track bed, and it is easy to occur the situation of conductive short circuit between the two rails, affecting railway safety monitoring. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a support assembly for a rail-bearing groove of a ballastless track bed, adopting a split structure to realize the buckling installation from the outside to the inside, and solving the inconvenience of installing a long-distance rail-bearing groove by threading.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A support assembly for a rail-bearing groove of a ballastless track bed includes a first fastener and a second fastener that abut against each other. The first fastener includes a first abutting surface that abuts against the side surface of the rail. The top end of the first abutting surface extends to the second fastener through the top surface, bends downward to form a second abutting surface, and then bends again towards the second fastener to form a third abutting surface.

[0007] The second fastener includes a fourth abutting surface that abuts against the side surface of the rail-bearing groove. The top end of the fourth abutting surface extends to the first fastener through the top surface, bends downward to form a fifth abutting surface that cooperates with the second abutting surface, and then bends again to form a sixth abutting surface that cooperates with the third abutting surface.

[0008] The support component for the rail groove realizes mutual cooperation and restriction through the mutual abutment between two fasteners and the abutment with the rail groove and the rail, so as to maintain the stability of the support structure. During installation, first place the first fastener in the rail groove and abut it against the side of the rail, and then insert the fourth abutting surface of the second fastener into the rail groove along the side wall of the rail groove. When the abutting end of the second fastener falls into the second abutting surface of the first fastener, press down the second fastener, and the second fastener and the first fastener can be mutually buckled to realize the installation and fixation of the support component.

[0009] As a preferred solution, an insulating partition with an L-shaped structure is arranged between the first fastener and the second fastener at their abutting surfaces. Thus, insulation between the two fasteners of the support component is realized, and short circuit between rails is avoided.

[0010] Further as a preferred solution, the bottom surface of the third abutting surface of the first fastener abuts against the top end of the spike. Thus, the support strength of the support component can be effectively improved, and the stability of the support component can be further improved.

[0011] Still further as a preferred solution, the bottom surface of the insulating partition is folded back to form a second bottom surface, and the third abutting surface of the first fastener is inserted between the two bottom surfaces of the insulating partition and abuts against the top end of the spike through the second bottom surface.

[0012] The beneficial effects of the present utility model compared with the prior art:

[0013] 1. By adopting the mutually buckling first fastener and second fastener, the support component for the rail groove forms a split structure, so as to realize the buckling installation from outside the rail groove to inside the rail, which is convenient for the support construction of long-distance rail grooves.

[0014] 2. The insulating partition realizes the insulated connection between the two fasteners of the support component, avoids the short circuit between rails caused by the support component, and improves the safety and reliability of railway monitoring.

[0015] 3. The present utility model has the characteristics of simple structure, low cost, convenient installation and maintenance, strong practicability and good use effect, and is worthy of wide promotion and use. BRIEF DESCRIPTION OF THE DRAWINGS

The first fastener 2 includes a first contact surface 2-1 that contacts the side surface of the rail. The top end of the first contact surface 2-1 extends to the second fastener 3 through the top surface, bends downward to form a second contact surface 2-2, and then bends again in the direction of the second fastener to form a third contact surface 2-3.

[0023] The second fastener 3 includes a fourth contact surface 3-1 that contacts the side surface of the tie slot. The top end of the fourth contact surface 3-1 extends to the first fastener 2 through the top surface, bends downward to form a fifth contact surface 3-2 that cooperates with the second contact surface 2-2, and then bends again to form a sixth contact surface 3-3 that cooperates with the third contact surface 2-3.

[0024] An insulating partition 4 with an L-shaped structure is arranged between the first fastener 2 and the second fastener 3, between their contact surfaces, that is, between the second contact surface 2-2 and the fifth contact surface 3-2, and between the third contact surface 2-3 and the sixth contact surface 3-3. The insulation between the first fastener 2 and the second fastener 3 of the support assembly is achieved through the insulating partition 4.

[0025] The tie slot support assembly in this embodiment realizes mutual cooperation and restriction through the mutual contact between the two fasteners, as well as the contact with the tie slot and the rail, to maintain the stability of the support structure. During installation, first place the first fastener 2 in the tie slot and contact it with the side surface of the rail, then place the insulating partition 4 at the second contact surface 2-2 and the third contact surface 2-3 of the first fastener 2. Then insert the fourth contact surface 3-1 of the second fastener 3 into the tie slot along the side wall of the tie slot. When the contact end of the second fastener 3 falls to the second contact surface 2-2 of the first fastener 2, that is, when the included angle between the fifth contact surface 3-2 and the sixth contact surface 3-3 of the second fastener 3 abuts against the longitudinal surface of the insulating partition 4, press down the second fastener 3, and the second fastener 3 can be mutually fastened with the insulating partition 4 and the first fastener 2 to realize the installation and fixation of the support assembly. Thus, the installation from outside the tie slot to inside the tie is realized, which is convenient for the support construction of long-distance tie slots, and the insulating connection between the two fasteners of the support assembly is realized through the insulating partition, avoiding the short circuit between the rails caused by the support assembly and improving the safety and reliability of railway monitoring.
