Technical Field

The invention relates to the technical field of railway installation, in particular to a detection and repair robot for a rail.

Background

Railway transportation is a type of land transportation in which a locomotive pulls a train vehicle over two parallel rails. The rails provide an extremely smooth and hard medium on which the train wheels roll with minimal friction, making the upper person more comfortable, and it also saves energy. If properly configured, rail transport can save five to seven costs of energy over road transport when carrying the same weight. Moreover, the rails can evenly disperse the weight of the train, so that the loading capacity of the train is greatly improved.

When the rail is subjected to impact and friction for a long time, the rail can generate various degrees of abrasion, and the general abrasion forms are three, namely side abrasion, vertical abrasion and wave abrasion. And after the rail is excessively worn, the rail needs to be replaced in time, so that potential safety hazards are eliminated. The rail replacing process comprises the following steps: removing the elastic fastener, cutting the old steel rail, replacing the old steel rail with a new steel rail, re-fastening the fastener, welding the steel rail and polishing the joint.

As shown in fig. 8 to 9, the storage unit includes a rail slot 36 disposed between the front and rear inner side walls of the vehicle body 1, and the rail slot 36 is parallel to the advancing direction of the vehicle body 1 and is located between two rails 3.

In this embodiment, the rail clamping groove can be used for placing new rails and replaced old rails, and is convenient to recycle.

As shown in fig. 10, the conveying unit includes two third box bodies 37, the third box bodies 37 are fixedly connected to the bottom surface of the vehicle body 1, and are respectively located on the left and right sides of the rail clamping groove 36 and between the two first openings 12, the length direction of the third box body 37 is parallel to the rail clamping groove 36, the top surface of the third box body 37 is open, a conveying belt 38 moving from the detaching unit to the installing unit is installed in the third box body 37, a plurality of grooves 39 for placing the elastic fasteners 5 are arranged on the conveying belt 38 along the conveying direction, and avoidance holes 40 for avoiding screws are arranged in the grooves 39;

the top of the third box 39 is further provided with a cleaning brush 41 for cleaning the elastic fastener 5 and an oil pot 42 for spraying lubricating oil to the elastic fastener 5, and both the cleaning brush 41 and the oil pot 42 are erected above the conveyor belt 38.

In this embodiment, put into the recess with elastic fastener when dismantling the unit, under the action of gravity, elastic fastener's screw is flagging dodging downtheholely, and conveyer belt work drives elastic fastener and moves to the rear, and the cleaning brush cleans elastic fastener, and the lubricated screw of oilcan spraying lubricant, the follow-up locking of being convenient for.

As shown in fig. 11, the cutting unit includes a first cutting assembly and a second cutting assembly symmetrically disposed on the left and right inner sidewalls of the vehicle body 1, and the first cutting assembly and the second cutting assembly are respectively located at a first opening 12;

the first cutting assembly and the second cutting assembly respectively comprise a second sliding block 43, second sliding grooves 44 are formed in the left inner side wall and the right inner side wall of the vehicle body 1, the length direction of the second sliding grooves 44 is parallel to the advancing direction of the vehicle body 1, the second sliding blocks 43 are slidably located in the second sliding grooves 44, fourth threaded rods 45 are further arranged in the second sliding grooves 44, the second sliding blocks 43 are sleeved on the fourth threaded rods 45 and are in threaded connection with the fourth threaded rods 45, fifth motors 46 are further arranged in the second sliding grooves 44, output shafts of the fifth motors 46 are fixedly connected with the fourth threaded rods 45, third telescopic rods 47 are mounted on the second sliding blocks 43, the telescopic ends of the third telescopic rods 47 respectively point to the rails 3 on one side, sixth motors 48 are fixedly connected with the telescopic ends, and saw blades 49 are fixedly connected to output shafts of the sixth motors 48.

In the embodiment, after the vehicle body moves to the position near the damaged rail, the fifth motor is started to drive the fourth threaded rod to rotate, the fourth threaded rod drives the second sliding block to slide in the second sliding groove, the third telescopic rod extends out to drive the sixth motor and the saw blade to cut the old rail, the old rail is grabbed by the disassembling unit and the installing unit and is placed in the storage unit, the new rail is grabbed and is placed in the original rail, and after the elastic fastener is locked again by the installing unit, a worker performs rail welding work;

the cutting unit can move in the second sliding groove, so that the cutting unit is convenient to adapt to rail cutting with different lengths, and the cutting unit can be used for cutting an old rail and can also be matched with the dismounting unit and the mounting unit to cut a new rail.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting the same, and although the present invention is described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that: modifications and equivalents may be made to the embodiments of the invention without departing from the spirit and scope of the invention, which is to be covered by the claims.
