Sleeper evenly arranging device and evenly arranging construction method used for group-sleeper-type sleeper laying unit

Abstract

The invention discloses a sleeper evenly arranging device and an evenly arranging construction method used for a group-sleeper-type tail laying unit. The sleeper evenly arranging device and the evenly arranging construction method used for the group-sleeper-type tail laying unit have the advantages that automatically and evenly arranging working of sleepers is achieved, foundation is established for successful development of a group-sleeper-type long-sleeper sleeper laying unit, a sleeper laying working manner of a ballast seamless track is radically changed, and due to the fact that during a sleeper laying construction process, the sleepers are horizontally conveyed in a natural state mode, the group-sleeper-type long-sleeper sleeper laying unit works stably, the phenomena of sleeper-clamping and sleeper-turnover are avoided, and impact on an sleeper laying mechanism caused by the sleepers is eliminated. Compared with a sleeper laying unit with a single sleeper method, the group-sleeper-type tail laying unit with the sleeper evenly arranging device eliminates a multi-level sleeper conveying mechanism, the structure is greatly simplified, various mechanisms are relatively independent, working is reliable, maintenance is convenient, sleeper laying accuracy is high, adaptability to the track is good, and a mechanization working degree is high.

Description

technical field [0001] The invention relates to the construction field of ballasted seamless railway sleeper laying, in particular to a sleeper leveling device and a leveling construction method for a group sleeper type track laying unit. Background technique [0002] In recent years, the construction technology of ballasted railway seamless track with a speed of 200km / h in my country has developed rapidly. The "replacement method" and "single sleeper method" long track laying units laying sleepers are the main construction methods for ballasted railway seamless track. The traditional "replacement method" is gradually seldom used due to low work efficiency and complicated procedures. Most track-laying constructions with tight construction schedules use long-track track-laying units to lay sleepers on the construction site. Therefore, long-track track-laying units and their application technology With considerable development, it has taken more than ten years from the introdu...

Problems solved by technology

In terms of the structure of the track laying machine, in order to ensure that the sleeper can be smoothly transferred to the sleeper distribution mechanism, the structural design of the sleeper transfer mechanism is relatively complicated, with many related parts, and its cost is expensive. The unit price of the imported track laying unit is about 40 million yuan. The price of the same type of equipment is about 20 million; from the actual use situation, during the operation process of the "single sleeper method" long track laying unit, the sleeper needs to be relay-transmitted to the cloth sleeper through a three-stage transmission chain with a certain inclination angle. Mechanism, often due to sleeper tilting, the phenomenon of sleeper jamming and overturning occurs. On the other hand, the heavier sleeper has a greater impact on the sleeper mechanism during the placement process, resulting in easy damage to the components of the sleeper mechanism, and a relatively high failure rate of equipment

[0003] The group-pillow long-track track-laying unit is an innovative track-laying equipment based on the concept of the single-pillow long-track track-laying unit. The meaning is that the sleepers are laid in groups (or groups) instead of one by one, that is, the N sleepers are evenly arranged so that the error of the distance between the sleepers is within the allowable range, and then they are laid on the ballasted track bed at one time to carry out the sleeper laying operation The process involves the technical problem of how to separate the close sleepers evenly and ensure that the sleeper spacing conforms to the construction specifications. Therefore, the group sleeper long track laying unit must solve the problem of evenly arranged sleepers, that is, the sleeper uniform layout. This problem is also the development of the group sleeper track laying unit. The bottleneck and difficulty of the work, it is reported that there is no group sleeper long track laying unit with mature technology and advanced functions at home and abroad.
