Description
Technical Field
The invention relates to a railway turnout transport and paving integrated machine and a transport method thereof, which are used for construction machinery for railway turnout whole-group dismantling, whole-group transport and whole-group paving, and belong to large-scale railway construction equipment.
Background
In China, railway turnout replacement is generally carried out in a mode of matching small machinery with manual work at present, namely, a new turnout is prefabricated and assembled at a proper place near the turnout to be replaced in advance, the construction is started, the prefabricated and assembled new turnout is transversely moved to an existing line through a transverse moving slide rail, then transversely and longitudinally moved to the front and back of the turnout to be replaced or transversely aligned along the existing line, and the transverse moving slide rail or the longitudinal moving slide rail is adopted for positioning construction. In the process, old turnouts need to be dismantled at a construction site after being dismantled, an operator needs to loosen fastener bolts by using a bolt tightening machine, the operator needs to cooperate with a rail crane or an excavator to gradually hoist and mount steel rails and sleepers, the excavator needs to manually lay transverse and longitudinal movement sliding rails after being grooved, lifting turnouts need to be jacked by operating jacking equipment (currently, the domestic main jacking equipment is a portal type elevation hydraulic rail lifting machine and a single-column combined turnout exchange and laying machine set) by the operator, turnouts need to be accurately adjusted transversely and longitudinally by the operator after falling to the ground, the machines used in the whole process all belong to manually operated small-sized machines, and the construction method of the generally adopted transverse and longitudinal movement sliding rails mainly has the following defects: (1) the selection of a prefabricating place is difficult, and a suitable place is difficult to be arranged near a turnout to be changed; (2) the construction process is multiple, the occupied time is long, the construction delay is often caused, and the transportation order is disturbed; (3) the number of constructors is large, the number of small-sized construction machines is large, the operation field is narrow, and the personal safety hidden danger is large; (4) in order to avoid construction delay, people and sea tactics are often adopted, and labor is seriously wasted; (5) the prefabrication and construction operation efficiency is limited by transportation conditions and skylight time, and the labor efficiency is low; (6) the used small machines have various and large quantity, and the workload of loading, unloading, transportation, maintenance and repair is large; (7) the construction cost is high and the economy is unreasonable due to the fact that a plurality of constructors and construction machines are provided. In individual construction in China, medium-sized equipment such as CPH type turnout changing and laying machine of Kunming medium-sized railway large-scale road maintenance machinery group limited company is adopted, the CPH type turnout changing and laying machine adopts the principle of an upper computer and a lower computer, and still needs to lay a longitudinal traveling rail, so that compared with the traditional construction method of transversely and longitudinally moving into place along the existing road, the construction method does not save time, and the equipment is not suitable for the transverse moving construction working condition and cannot solve the problem that the level of the turnout exceeds the limit and scrapes and touches a signal machine and other equipment during longitudinal moving.
Internationally, there are switching devices such as a switching machine of gisman, a gantry crane of ICE switch, a switch machine and a transport vehicle of DESEC, finland, and a four-column switch self-propelled crane frame of Plasser. The France Gisca turnout replacing machine still needs to lay a running rail like the CPH turnout replacing machine of Kunming medium-sized railway large-scale road maintenance machinery group limited company, and the construction time is not saved compared with the construction of the traditional transverse and longitudinal moving-in method along the existing road; the German ICE laying turnout gantry crane needs to pre-lay a gantry crane track in advance and cannot be widely applied due to the limitation of an operation field; the turnout paving machine and the turnout transport vehicle of Finland DESEC company are two kinds of equipment, and the transportation and the laying are separated, and the turnout is transported and laid in a way of inclined loading in sections, so that the field connection is time-consuming and labor-consuming; the four-column switch jack frame of the company Plasser & Theurer is not universally applicable due to site limitations.
In a word, at present, no large-scale construction equipment which can be widely applied, completely solves the problems of turnout transportation and laying, is generally applicable and integrates transportation and replacement and laying is available at home and abroad.
