A kind of long rail change rail fastener collection device

Abstract

The invention discloses a collection device for rail-changing fasteners for long steel rails, comprising: a flatbed car, a transfer belt conveyor, and a bucket chain conveyor; two-spoke guide rails are arranged on the bottom plate of the flatbed car, and there are two support rollers on both sides of the left end of the flatbed car; the transfer belt The machine is a horizontal belt conveyor. The transfer belt conveyor can move back and forth on the flatbed. The bucket chain conveyor includes: a horizontal fixed frame and a swing lifting frame, a chain with an iron bucket suspended, and a sprocket. The iron bucket is used for loading recovered fasteners ;The horizontal fixed frame and the swinging lifting frame are hinged by hinge ears; the lower part of the swinging lifting frame is supported by the support rollers, and the lower part of the left end of the swinging lifting frame has a supporting wheel that can be supported on the rail. When the fastener is recovered, the swinging lifting frame extends The flatbed car is carried outside and carried on the rails. After the fasteners are put into the iron bucket, they can be sent into the flatbed car. When not working, the swing lifting frame can be electrically or manually retracted into the flatbed car in emergency situations. The structure is simple, the retraction is convenient, and the operation is safe.

Description

technical field [0001] The invention relates to a collection device for rail-changing fasteners of long steel rails, which belongs to the technical field of railway maintenance equipment. Background technique [0002] The rail fastener is a part used to connect the rail and the sleeper on the track. Its function is to tightly fix the rail on the sleeper, and to control the distance between the two rails and the height difference of the rail surface to prevent the rail from moving longitudinally and laterally relative to the sleeper. The composition of rail fasteners mainly includes elastic or rigid fasteners (spring bars, gussets), under-rail pads (large rubber pads), gauge blocks for adjusting the gauge, nylon shoulder pads and nuts, etc. (see Table 1 below. ). [0003] Table 1 Parameters of components of long rail fasteners [0004] [0005] As can be seen from Table 1, whether it is a type II pillow or a type III pillow, the total weight of the old fasteners per kilo...

AI Technical Summary

Problems solved by technology

[0006] In view of this, there are also a variety of inventions or new patents that have been disclosed, aiming at solving this problem. For example, the Chinese new patent "Recycling and Transmission Device for Sleeper Fasteners" (201520578992.6) puts the recycled fasteners on the receiving hopper before pushing them On the conveyor belt of the movable conveyor, the fixed conveyor transports the fasteners conveyed from the movable conveyor to the middle position of the road flatbed truck. The disadvantage is that the operation process of releasing or retracting the movable conveyor is complicated and particularly difficult. Control will affect safe production. On the other hand, the fasteners are easy to slip when walking on the conveyor belt of the movable conveyor; the new patent "A Rail Fastener Recovery Device" (201420460652.9) also suffers from the complicated operation of retracting and unloading the lifting conveyor. , the safety factor is low, the fasteners are easy to slip on the conveyor belt, etc., and the electromagnetic roller can only collect iron pieces; the conveyor belt of "A Fastener Recovery Vehicle" (201120534220.4) is installed on a long belt conveyor, and the belt conveyor It is difficult to retract and unwind. During operation, the upper end of the belt conveyor is close to the railway electrical catenary, which is extremely unsafe; the invention patent "A Device and Method for Recovering Rail Fasteners" (201410401450.1) also has complicated devices and high overall structure. The center of gravity is high, and it is close to the railway electrical contact network, so there are safety hazards and other problems

[0007] Due to the very limited controllable time nodes for construction on the railway, there are common problems in the disclosed technical solutions: the released fastener recovery device cannot be recovered immediately when there is an electrical or hydraulic failure. If there is no manual emergency treatment operation device, it cannot be retracted safely and effectively, which will affect the opening of the line blockade construction section, and even cause safety accidents in severe cases
