Abstract

The rail kit is attached to the steel pillow on the bridge. Aims to be Option for the use of the bridge guard rail anchor kit. By piece of sheet The wrought iron will be welded to the rail box. And both parts will be welded to the inner pillow. Small pillow factory And at each rail box there will be drilling holes in two sizes The two parts of the drilled holes are connected by a larger hole than the head of the bolt (Head Bolt) is located on the side of the ductile iron plate. To be able to insert the bolt (Bolt) and the drill holes that are similar to the size of the bolts (Bolt) are on the side of the rail box. To be used to lock the bolt (Bolt) when sliding the bolt into position. The hole is drilled near the size of the bolt (Bolt) at the end of the rail box already. Then put the components Such as steel plate, washer (Washer), double coil spring washer (Double coiled spring washer), Nut key in order. To be used as a fastener for the rail together tightly with the rail box Ready to tighten the hold This invention can prevent the theft or loss of the bolt, which is a locked piece. The wooden tracks can be loosened out of the way as well.

Claims (5)

1. A set of devices for anchoring rail to the steel pillow on the bridge Consists of a box rail (1) is a square box. The side consists of 3 steel plates with the bottom part of the box, the rail (1) used to attach to the steel pillow And the outward-facing part of the rail box (1) is welded to the ductile iron plate (2) which is L-shaped by the end of the wrought iron plate (2) in the arc. Turn the rail into the box (1), which will fit into the base of the rail. To be used for fixing The rail base prevents moving. And on the top of the rail box (1), there are two sizes of drilled holes welded together by a large drilled hole (12) and the head of the bolt (Head Bolt) can be placed on the side of the steel plate (2) and the hole. Drill (9) which is as small as the size of the bolt body. It is at the end of the rail box (1) facing inward. By the end of the rail box (1) opposite to the ductile iron plate (2) will insert the bolt (Bolt) (3) through the drilled hole (12) and slide it into the drilled hole position (9) to use for Assembled with various parts of the kit. In order to attach to the rail base from moving, the rail is then placed onto the rail box (1) with one side of the rail base inserted into the arch of the wrought iron plate (2) and the rail base together. Cover the drilled hole (12) and insert a steel plate (7) with a drilled hole (11) equal to the size of the drilled hole (9) into the bolt body (Bolt) 3 by the bottom base of the steel plate (Steel plate) (7), one side (10) can be completely covered on the rail base. The bottom base of the steel plate (7), the other side is completely sealed against the top of the rail box (1), washer (6) and double coil spring washers ( Double coiled spring washer) (5) that is inserted into the bolt body (3) respectively and placed on a steel plate (7) to support the weight and absorb the shocks from the train when the train. Causes oscillation or derailment and prevents loosening of the nut (4) on the top of the double coiled spring washer (5) by the nut (4). Is put on the bolt (3) lastly By tightening the bolts (Bolt) (3) to prevent Movement of bolts (Bolt) (3), Steel plate (7), Washer (6) and Double coiled spring washer (5). In particular, the rail box (1) has two sizes of holes, drilled holes (12) and drilled holes (9), both of which are drilled. Will be connected by the drilled holes (12) on the side of the plate, the steel plate (2) will be larger than the head bolt so that the bolt (3) can be inserted and the drilled hole (9) It is slightly larger than the Bolt (3), which drilled holes (9) are located on the side of the rail box (1) for sliding the bolts (Bolt) (3) into position. In order to insert the components, such as Steel plate (7), Washer (6), Double coiled spring washer (5), Nut. ) (4) respectively to be used as a rail anchor for Tightly attached to the rail box (1), this invention prevents theft or loss of Bolt (3), the piece that locks the rail from falling out of the way. Since the bore hole (12) is designed in the position where the rail is pressed, if the bolt (Bolt) (3) is to be removed, the rail must also be lifted. 2. A set of devices for anchoring rail to the steel pillow on the bridge According to claim 1, the drill hole (12) has a large geometric shape. To be able to insert the head of the bolt (Bolt) (3). 3. A set of devices for anchoring rail to the steel pillow on the bridge According to claim 1, the part of the wrought iron plate (2) L-shaped (L) in connection with the rail box (1), which allows the ends of the wrought iron plate (2) to bend towards the rail box (1). ) By the distance between each rail box (1) to the end of the part The bends of the ductile iron plates (2) are designed to fit each rail base. 4. A set of devices for anchoring rail to a steel pillow on the bridge According to claim 1, the section of the double coiled spring washer (5) has a spiral characteristic Springiness To be used for absorbing the impact that has been applied to the invention. And prevent loosening Of the nut (4) 5. A set of devices for anchoring rail to a steel pillow on the bridge According to claim 1, the part of the steel plate (7) has a geography shape. At the bottom of the steel plate (7) the bottom base design (10) One side of the base can be covered on the rail base, and the bottom of the other side can be covered on the rail box (1 )
