So left running gear 100 and right running gear 300 advance and punch alternately, accomplish the restriction to hole interval through clamping assembly 130, locating pin 112 and telescopic machanism 200's cooperation, avoided because of wheel 141 skid the inaccurate location that leads to on rail a, influence the drilling interval and make the unable smooth installation of railway track rail side equipment. Meanwhile, accumulated errors caused by continuous punching for many times can be reduced as much as possible, and the distance between the mutually related mounting holes can be ensured not to exceed the allowable errors. That is, a plurality of holes with size correlation are required for the trackside equipment installation of one railway track, and the railway track drilling machine can ensure that the accumulated error of one group of installation holes is within the allowable range. The railway track drilling machine can ensure the accuracy of the distance of the adjacent railway track side equipment and the distance of the adjacent railway track side equipment exceeds the magnitude of accumulated errors.
It will be apparent that when only one rail a is perforated, both rails a still need to be perforated to ensure the hole spacing.
In the present embodiment, since a plurality of drilling assemblies 110 may be provided in the left and right traveling mechanisms 100 and 300, the drilling assemblies 110 may drill a plurality of holes every time the traveling mechanism advances, thereby further reducing accumulated errors. Taking the left running mechanism 100 as an example, after the first drilling, the positioning pin 112 of one drilling assembly 110 penetrates into the hole to complete positioning, and the other drilling assembly 110 can drill the rest of the holes within the range of travel, so that the errors between the rest of the holes do not accumulate to the next drilling of the right running mechanism 300.
In short, if the travelling mechanism is provided with only one drilling assembly 110, only one hole can be drilled in each advance, and the distance of each advance is limited by the hole pitch, so that frequent alternate advance can be caused, and error accumulation is easily caused. When two drilling assemblies 110 are provided, the integral accumulated error is accumulated only when the holes are drilled alternately, and the error among a plurality of holes drilled in each advance is accumulated only when the holes are drilled, so that the next advance is not influenced.
That is, by reasonably setting the relative movement distance of the drilling assembly 110 and the telescopic length of the telescopic mechanism 200, any number of drilling holes at any interval can be realized with the minimum advancing times, and the total accumulated error can be greatly reduced due to the fewer advancing times.
Based on the railway track drilling machine provided by the embodiment, a railway track drilling method is provided, which comprises the following steps:
s100, drilling a starting hole: drilling assembly 110 on left running gear 100 and/or right running gear 300 drills rail a first time to obtain a starting hole;
s200 locked position: according to the drilling requirement, the positioning pin 112 of one of the left traveling mechanism 100 and the right traveling mechanism 300 is inserted into the starting hole;
s300, drilling a second hole: the telescopic mechanism 200 pushes the other of the left traveling mechanism 100 and the right traveling mechanism 300 to advance to the second hole position and drill by the drill assembly 110;
s400: the locking position step and the second hole drilling step are then repeated, so that the left traveling mechanism 100 and the right traveling mechanism 300 alternately advance and drill holes.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
