Problems solved by technology

[0004] It can be seen from the manual pushing of the rollers from under the rails that the operation of manually pushing out the rollers not only increases the labor cost, but also is slow and inefficient. At the same time, it is difficult to make the position of the rollers manually pushed and placed neatly. Fast and accurate grasping by one-step manipulators is very unfavorable, all of which will seriously affect the progress of the entire track laying system

Embodiment 1

[0042] like figure 1 , 2 , shown in 3, a kind of device designed by the above-mentioned method that the roller 27 that is used for rail dragging under the rail 30 is dragged out, comprises the rail lift mechanism 110 that is arranged on the both sides of roller recovery vehicle 100, also includes the mechanism that is located at the recovery The active frame 2 on the car 100, the retrograde parking mechanism arranged between the active frame 2 and the recovery vehicle 100, the transverse drive mechanism arranged on the active frame 2, the longitudinal fine-tuning mechanism located on the transverse drive mechanism, and the longitudinal fine-adjustment mechanism The upper lifting mechanism and the hook part located at the lower end of the lifting mechanism. The rail lifting and sliding mechanism 110 arranged on both sides of the drum recovery vehicle 100 has two horizontally arranged pulleys 32, which are respectively added between the rail head 31 and the rail bottom on both ...

Embodiment 2

[0064] like Figure 10 As shown, a device for pulling out the roller 27 used for dragging the rail under the rail 30 is different from Embodiment 1 in that: the hook component includes a hook frame 33, an electromagnet that is arranged at the lower end of the hook frame 33 Suction cup 34, electromagnetic suction cup 34 is towards the left side or the right side of track bed 26 under the car belly. Correspondingly, the front and rear ends of the roller frame 28 are made of magnetic material such as iron, or a magnetic plate is directly installed. A strong electromagnetic coil is arranged in the electromagnetic chuck 34 to control the suction and release of the roller frame by cutting off the current. During application, the electromagnetic coil is energized, so that the electromagnetic chuck 34 is close to the roller frame 28, and after sucking the roller frame 28, the roller 27 is dragged to a limited position, and then the power is turned off and released. The advantage of ...

Abstract

The invention discloses a method and a device for dragging out a roller used for dragging the steel rail below a steel rail, and the method comprises the following steps: arranging lifting and sliding mechanisms on two sides of a roller recovery vehicle, lifting a section of steel rail of which two sides are pressed on the roller by the lifting and sliding mechanisms, and enabling the lifting and sliding mechanisms to slide forwards along with the vehicle on the bottom surfaces of rail heads on two sides of the steel rail; and meanwhile, a dragging device which can move forwards and backwards on the roller recovery vehicle and can drag the roller out of the bottom of the steel rail is arranged on the roller recovery vehicle, and the dragging device moves backwards on the roller recovery vehicle when the roller recovery vehicle moves forwards during operation. And the dragging device and the ballast bed are kept relatively static for a period of time, the dragging device completes the action of dragging the roller out of the bottom of the lifted steel rail in the period of time, and then the roller recovery vehicle forwards moves forwards at the speed higher than the advancing speed of the roller recovery vehicle, and the next operation is started. The method has the advantages that the roller pressed under the steel rail can be quickly dragged out and accurately and normatively placed at a set position.

Description

technical field [0001] The invention relates to a method and a device for dragging out a roller used for rail dragging under a rail, and belongs to the technical field of rail transit rail laying. Background technique [0002] In the automatic track laying system, a roller that temporarily carries the rail and can drag the rail on it is used, and the roller has a roller frame that can be placed stably on the track bed. In the automatic track laying process, the front car pre-places the rollers on both sides of the ballast bed according to the gauge to provide temporary support with minimal frictional resistance for the rails on both sides of the back while falling and moving forward. When the rails on both sides of the ballast bed (one rail The length is about 500 meters) and then stop moving forward after falling on the roller. At this time, there is no roller placed under the steel rail with a length of more than ten meters at the rear end. The rear ends of the rails on bo...
