Collecting device for rail-replacing fasteners of long steel rail

Abstract

The invention discloses a collecting device for rail-replacing fasteners of a long steel rail. The collecting device comprises a flat car, a transport belt conveyor and a bucket chain conveyor, wherein two pairs of guide rails are arranged on a bottom plate of the flat car; two supporting rollers are further arranged at the two sides of the left end of the flat car; the transport belt conveyor is the horizontal type belt conveyor; the transfer belt conveyor can move front and rear on the flat car; the bucket chain conveyor comprises a horizontal fixed frame and a swing lifting frame, a chain suspended with an iron bucket and a chain wheel; the iron bucket is used for loading the recycled fasteners; the horizontal fixed frame and the swing lifting frame are hinged through a hinged lug; the lower part of the swing lifting frame is supported by a supporting roller in a sliding mode; the lower part at the left end of the swing lifting frame is equipped with a supporting wheel capable of being supported on the iron rails; while the fasteners are recycled, the swing lifting frame extends to the outside of the flat car and is supported on the iron rails; after being put into the iron bucket, the fasteners can be fed into the flat car; and while not working, the swing lifting frame can be manually retracted into the flat car under an electric condition and an emergency condition. The collecting device is simple in structure, is convenient to deploy and retract, and is safe to operate.

Description

technical field [0001] The invention relates to a long steel rail rail change fastener collecting device, 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 fix the rail tightly on the sleeper, and control and maintain the distance between the two rails, the height difference of the rail surface, and prevent the vertical and horizontal movement of the rail relative to the sleeper. The composition of rail fasteners mainly includes elastic or rigid fastening parts (elastic strips, buckle plates), 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 Component parameters of long rail fasteners [0004] [0005] It can be seen from Table 1 that no matter it is a type II pillow or a type III pillow, the total weight of old fasteners...

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 to solve 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 first and then pushes 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 parts; 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
