Description

Technical Field

[0001] The invention relates to the technical field of spacer irons, and in particular to a spacer iron of a raceway beam spacer device. Background Art

[0002] As we all know, rails are the main components of railway tracks. Their function is to guide the wheels of locomotives and vehicles forward, bear the huge pressure of the wheels, and transmit it to the sleepers. The spacer iron of the roller beam spacer is a special equipment to prevent the rails from lateral displacement during transportation. It is installed on the rail transport vehicle to ensure the stable transportation of the rails.

[0003] At present, my country uses long rail trains to transport 500-meter-long rails. Multiple rail transport vehicles in the train are responsible for loading long rails. There are three rail support devices on the rail transport vehicle, which are located at both ends and the middle of the vehicle. Each rail support device has four roller beams, which can load 4 layers of 56 long rails in total. Spacers are set on the four roller beams of the rail support device in the middle of the rail transport vehicle. During transportation, the spacers can keep the rails in place on the roller beams to prevent the rails from moving laterally and squeezing each other. The working component of the spacer used in the rail transport vehicle is an integrated spacer iron, which is A solid block with specifications of 80mm high, 50mm wide and 35mm thick, mostly made of Q235. The spacer device has a solid through shaft arranged along the length direction of the raceway beam. The through shaft is manually operated and can swing within a range of 90°. The spacer iron is welded to the through shaft and can swing with the through shaft to achieve two working states: standing up and lying down. When standing up, it can block the bottom of the transported rails to play a spacing role. When lying down, the spacer iron is located below the upper plane of the raceway beam. The long-rail vehicle set also has a rail unloading function, which can unload the transported rails on the designated line.

[0004] When a rail transporter transports 500-meter-long rails through a curved section, the curvature of the rails is different. The curvature of the rails on the inner side of the curve is greater than that on the outer side. When passing through a straight section, the rails return to a straight line, which causes the rails on the vehicle to have a longitudinal relative movement relative to the single rail transporter. During transportation, the rail bottom and the spacer iron will constantly rub due to this relative movement, causing the spacer iron to wear. During the unloading process, friction will occur between the rail bottom and the spacer iron, which will also cause the spacer iron to wear. When the spacer iron is severely worn, deep grooves will be worn on the spacer iron. Sometimes the spacer irons are even cut off, causing safety hazards to transportation and operation. Once the grooves worn on the spacer irons are stuck with the bottom of the rails, the spacer device and the raceway beam will be subjected to the longitudinal force caused by the relative movement of the rails during the transportation of the rails. This longitudinal force may exceed the design bearing capacity of the spacer device and the raceway beam, causing safety hazards. In order to avoid accidents caused by the wear of the spacer irons, the users of long-rail vehicles must frequently check and repair the spacer irons, which greatly increases the frequency and workload of long-rail vehicle maintenance. Even so, failures caused by the wear of the spacer irons still occur frequently. Summary of the invention

[0040] In summary, the working principle of the spacer iron of the raceway beam spacer device is as follows: when in use, the spacer iron of the raceway beam spacer device is first installed in a matching transport vehicle; during the installation process, an appropriate number of spacer irons of the raceway beam spacer device are selected according to the specific length specification of the long rail 1; when the long rail 1 needs to be loaded, the synchronous cylinder 7 is rotated to make the multiple spacer blocks 9 rotate and rise; when the multiple spacer blocks 9 are rotated and raised, the holes on the outer limit cylinder 41 and the holes on the synchronous cylinder 7 coincide with each other; pins are inserted into the coincident holes to achieve auxiliary limiting between the synchronous cylinder 7 and the outer limit cylinder 41, so as to maintain the upright state of the rotated and raised spacer blocks 9. The long rails 1 to be transported can then be loaded between the spacer blocks 9. When the long rails 1 are deformed due to turning during transportation, the relative position change between the bent long rails 1 and the spacer blocks 9 is achieved through the rolling assistance of the separation wheels 14, that is, through the rotation of the ball bearings 11, thereby reducing the direct contact wear between the spacer blocks 9 and the long rails 1. In addition, during transportation, when the long rails 1 change height due to factors such as bumps, the sliding friction between the long rails and the spacer blocks 9 in the up and down directions can be offset by the sliding bearings 13, thereby reducing the friction loss of the separation wheels 14 and increasing the service life of the equipment.

[0041] Furthermore, when multiple spacer blocks 9 need to be laid down synchronously, it is only necessary to rotate the synchronous cylinder 7 to achieve the synchronous laying down of multiple spacer blocks 9. When a single spacer block 9 needs to be laid down, the middle shaft rod 35 can be pulled relative to the synchronous cylinder 7, and the two driving side plates 37 can be synchronously adjusted in position in the synchronous cylinder 7 under the transmission action of the two side connecting rods 36, until the two driving side plates 37 are moved in the synchronous cylinder 7 to the corresponding positions of the spacer blocks 9 that need to be laid down, so that the middle connecting plate 32 in the spacer seat 8 fixedly connected to the spacer block 9 to be laid down enters the gap between the two driving side plates 37, and then the middle shaft rod 35 is rotated and adjusted relative to the synchronous cylinder 7 to achieve the synchronous rotation of the two driving side plates 37, and finally the two driving side plates 37 are achieved. The middle connecting plate 32 in the gap area between the driving side plates 37 is driven to rotate, and the driven middle connecting plate 32 realizes the rotational drive of the spacer seat 8 outside the middle connecting plate 32, and finally reaches the corresponding rotation and laying down of the spacer block 9. After the spacer block 9 is laid down, the holes on the inner limit cylinder 40 and the holes on the central axis rod 35 overlap with each other, and the auxiliary limit between the central axis rod 35 and the inner limit cylinder 40 can be achieved by inserting pins into the overlapping holes. There are multiple holes on the central axis rod 35, and the multiple holes correspond to multiple spacer blocks 9 respectively. In order to facilitate the identification of the corresponding driven spacer block 9 after the central axis rod 35 is adjusted relative to the synchronous cylinder 7, a corresponding mark can be set on the central axis rod 35 to facilitate the judgment operation during actual operation.
