Description

The railroad ballast paver

Affiliated technical field

The utility model belongs to the road construction field of mechanical technique, relates to a kind of paver that is used for quarrel laying construction at the bottom of the railway ballast.

Background technology

For a long time, this area particularly domestic construction of railways department for railway ballast at the bottom of the laying of quarrel generally all adopt the mode that manually paves, though can also reach the specification and requirement of common railway construction on the whole basically, there is bigger shortcoming its aspect such as uniformity at planeness, compactness and the broken stone metaling of laying layer.Along with the fast development of national economy in recent years and the continuous speed-raising of railway transportation, the implementation phase that high speed railway construction having entered, since high-speed railway to railway ballast at the bottom of quarrel lay layer planeness, compactness and broken stone metaling uniformity and require very strict to the stationarity of elastic carrier structure ballast bed of track, traditional artificial paving mode still all is difficult to reach the construction requirement of modernized railway in construction technology on operating efficiency, therefore present stage this area be badly in need of a kind ofly can carrying out the paver special that ballast aggregate paves.At present external existing same category of device is corresponding exists complex structure, costs an arm and a leg and safeguards deficiency such as inconvenience, and domesticly is exclusively used in the equipment that quarrel paves at the bottom of the railway ballast and also belongs to a blank.

The utility model content

The purpose of this utility model is at the existing problem of state of the art, and a kind of particularly railroad ballast paver of high-speed railway fundus ballast laying of railway ballast that is suitable for is provided.

Be used to realize that the technical solution of foregoing invention purpose is such: the railroad ballast paver that is provided is made of the screed of band pre-hammer ram of frame, driver's cabin, band of traveling crawler and main hammer ram and electrical apparatus control system, hydraulic control system etc., screed is located at the frame rear and is connected with frame by draft arm, be provided with a hopper at frame front, below hopper, be provided with a ribbon flight conveyer, the other end below of conveyer is provided with the distribution cabins of a band downward swing door, is provided with distributing device at the rear portion of frame.In the course of work, along with paver travels along railway ballast with the speed of paving, by paver promotion and accompanying with it material containing dump truck compound is sent into hopper, by drag conveyer material is sent to distribution cabins and will expects that by the distributing device before the screed branch is to both sides then, compound is delivered to after the hammer ram pre-compacted on the screed earlier under the screed vibrating bottom plate again and is pressed and compacting, finally forms the single line or the two-wire railway roadbed of construction requirement.

The specific embodiment

Referring to accompanying drawing, railroad ballast paver described in the utility model comprises parts such as frame, driver's cabin 1, screed 3, draft arm 5 and the electrical apparatus control system of being with traveling crawler 6, hydraulic control system, on frame, be provided with the compound induction system that constitutes by hopper 9, drag conveyer 7 and distribution cabins, join by draft arm 5 between screed 3 and the frame.Paver driver's cabin 1 adopts totally enclosed metal driver's cabin and is furnished with high-power air conditioner, and dust is very big when paving owing to ballast aggregate, when adopting totally-enclosed metal driver's cabin can make tractor driver's operation a good environment is arranged, and helps the healthy of tractor driver.Between draft arm 5 and screed 3, be provided with screed thickness adjusting plate 2, both can increase distance between main frame rear wall and the screed antetheca by this adjustable plate 2, also can improve the elemental height of screed, distribution cabins makes distributing device will be cut the stone uniformly dispersing on roadbed fully with regard to enough spaces are arranged like this, overcome because of the less mobile adverse influence of distribution cabins, also reduced simultaneously the extruding and the wearing and tearing of the distributing device blade that causes because of the storing space is too small, screed antetheca etc. quarrel stone.Distributing device is located at the rear portion of frame, below distributing device, be provided with a secondary high abrasion large helix angle blade wheel 4, because the particle diameter of ballast aggregate is big, mobile poor, therefore divide in respect of large helix angle, major diameter blade at distributing device, its material mixture ratio and heat-treatment protocol make blade have higher impact toughness and scuff resistance, both can significantly reduce the loss of helical blade, and can reduce use cost again.The cross section structure of the material-conveying belt of drag conveyer 7 as shown in Figure 3, it is divided into two-layer, its lower floor is the material scraping plate that spacing is encrypted, the upper strata is a flakey high-strength abrasion-proof rubber conveyor belt, adopt the flakey conveyer belt can effectively increase carrying and the conveying capacity of transportation belt body to hard coarse aggregate (ballast aggregate), aggregate does not directly contact with material scraping plate with base plate, the life-span that has alleviated wearing and tearing greatly and improved conveyer belt.Screed 3 base plates are provided with able to quickly change formula high abrasion template, can directly form groove in the middle of the quarrel face when the single line railway roadbed paves, and can directly form symmetrical grooves on the quarrel face when the two-wire railway roadbed paves, and form consistent compactness on whole cross section.The wear rib inboard of screed installs the yielding rubber pad additional, alleviates between screed master, pre-hammer ram and screed antetheca three rubbing surface pressure and wearing and tearing with this, makes the hammer ram can normal guide and compacting, satisfies the compactness requirement that ballast aggregate paves.Number in the figure 8 is for can be used for promoting the push roller of dump truck.

Railroad ballast paver described in the utility model have the efficient of paving height, effective, constructing operation convenient, economize on the use of funds and advantage such as economic results in society are considerable.The operation travel speed of paver generally is controlled at (stepless speed regulation) between 0～16m/min, and laying depth 0～400mm lays width 2.5～9.0m, but ballasting particle diameter 25～70mm, and the laying amount maximum of ballast aggregate can reach 500t/h; Lay the surface course that forms by this ballast aggregate paver and have higher planeness, planeness 3m ruler is measured the discrepancy in elevation, the hammer ram frequency 24.5Hz (stepless speed regulation) that vibrates can make the compactness of whole shop layer reach more than 90% like this, and the stability of track is had laid a good foundation for future; In addition, use this ballast aggregate paver to carry out the broken stone metaling laying construction, can satisfy the uniformity of the planeness of laying layer, compactness, broken stone metaling fully and to the stationarity requirement of elastic carrier structure ballast bed of track, owing to cancelled the rolling apparatus that former artificial laying needs, cargo handling operation is greatly reduced, not only be convenient to construction but also can save substantial contribution, the railway roadbed external form after paving is smooth, attractive in appearance, and the size of the groove that forms meets construction technical requirement fully.
