Description
Technical field
The present invention relates to a kind of running machinery of railway construction machine, particularly a kind ofly be used to change the switch tracks guard rail hoisting device of working vehicle of gapless track.
Background technology
At present; in the prior art; the running mechanism of railway construction machine is not provided with special counter-rail apparatus; with the erectility of assurance track and the constant distance between the two rails; and switching tracks; changing pillow waits in the construction of railways operation process; rail to be in inevitably be not fixed or not quilt be completely fixed state; under this state; the phenomenon that rail very easily occurs tilting or is offset; distance between the two rails also is difficult to protect constant, and the wheel of running mechanism is to very easily sliding down in operation process, in case slide down like this; can only be by large-scale jack or the large-scale lifting machinery of long-distance allocation and transportation, whole multiple process complexity; cycle is long.
The for example present railway machinery that switches tracks all is not provided with guard rail machinery, as Chinese patent CN2263610Y, CN2871617, CN2510526Y, CN1152169C discloses the dissimilar replacing track machines that are adapted to different purposes, the method that is adopted generally is that new rail is put in by the old rail and after removing most of fastener of old rail, while walking old rail is moved away from rail support groove piecemeal continuously by mechanical, the limit is placed in the mode of working continuously in the rail support groove piecemeal continuously with new rail, in this operating type, the front and back wheel of working vehicle is to traveling on new rail or old rail respectively, new rail or the old rail of this moment all are in not by the fastener tightening state, because new rail and old rail are all because of taking place laterally in the process of switching tracks, length travel and need bear big active force, new rail and old rail all are difficult to guarantee to remain erectility, in case track run-off the straight or gauge are excessive, very easily cause construction mechanisms such as working vehicle security incident such as slide down or tumble, general processing method all need just can be finished reseting procedure by other equipment, as adopt crane that construction machinery integral body such as working vehicle are sling, manually fit into road wheel to resetting, or adopt a plurality of hydraulic jacks to withstand on different positions construction machinery is supported jacking to certain height, again by manually fitting into road wheel to resetting, in this process, because bogie of the prior art is not fixed into one in vertical direction, in the car body uphill process, bogie part needs jacking separately once more usually, just can finish steering framing wheel to the contraposition of track, reset.Because car body self does not possess and plays multiple function voluntarily, the site requirements of hoisting operation and equipment require all higher, the operating worker number that plays multiple process is more, constructor's safety is difficult to guarantee, need carry out a large amount of operation preparation, operation time is long, the task of switching tracks of generally can not finishing on schedule, and it is normally open-minded to influence circuit.
All there is the shortcoming that the activity duration is long, operation process is dangerous in of the prior art compound method, and the mode of especially slinging needs promptly to allocate and transport large-scale crane especially to on-the-spot, is pressed for time, and the place is restricted, has brought very big difficulty to construction.Therefore, railway construction machine of the prior art need be provided with self guard rail hoisting device, with the needs that are adapted to fast, safety resets.
Summary of the invention
Purpose of the present invention is exactly at above-mentioned present situation, a kind of guard rail hoisting device of railway construction machine is provided, it can make in the work progress track that needs carrying but the be not completely fixed state of being kept upright, prevented the generation of the accident that slides down to the full extent, it is multiple that the railway construction machine that slides down is risen fast, and safety resets.
Another object of the present invention is to provide a kind of guard rail hoisting device of the working vehicle that switches tracks, it it can make the track that needs carrying in the process of switching tracks but be not completely fixed keep the state that stands up, prevented the generation of the accident that slides down to the full extent, it is multiple that the industry car that switches tracks that slides down has been done fast, and safety resets.
