Description
Technical field
The present invention relates to a kind of measurement mechanism, particularly a kind of overhead travelling crane span measurement mechanism.
Background technology
General overhead travelling crane span adopts routine measurement farad steel tape method to measure, but for span comparatively large (more than 34.5m), and exceeded steel tape modified value scope (see table 1), correct correction of cannot tabling look-up records numerical value.When survey crew is measured, measure two orbit centre gauges with 50m steel tape, simultaneously by spring balance tension steel tape, repetitive measurement numerical value sums up process, and because survey crew physical efficiency limit, cannot complete whole across measuring process, it produces measuring error.In measuring process, survey crew need be stood to track both sides, and survey crew causes larger potential safety hazard (see Fig. 1).Meanwhile, adopt routine measurement method, need operate a switch whole across crane slip power supply, cause the whole crane that collapses cannot operation, and the used time be longer, the production run at scene is caused to having a strong impact on.
Period also adopts transit survey, but requires higher to site environment, produces vibration influence, still cannot meet on-the-spot actual measurement requirement due to tested across by adjacent across crane job.
So far, due to cannot exact value be recorded, therefore effectively can not adjust and service crane cart gauge, cause crane rotation browsing rail serious.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of structure is simple, easy and simple to handle, operating speed overhead travelling crane span measurement mechanism soon and accurately.
For reaching above-mentioned purpose, a kind of overhead travelling crane span of the present invention measurement mechanism, described measurement mechanism comprises housing and reflecting plate, described enclosure interior is provided with laser range finder, both sides, below are respectively equipped with bottom plate, wherein bottom plate described in side is provided with and regulates trapped orbit screw rod, and housing sidewall corresponding above it is provided with laser range finder and regulates standing screw, and described reflecting plate is used for the laser reflection that described laser range finder is launched to return described laser range finder.
Wherein said housing upper opening.
Wherein said housing is formed by the Plate Welding that 2mm is thick.
Wherein said bottom plate is the steel plate that 2mm is thick, and described bottom plate and described case weld form.
Overhead travelling crane span measurement mechanism difference from prior art of the present invention is that the present invention achieves following technique effect:
After overhead travelling crane span measurement mechanism of the present invention adopts laser range finder, comparatively conventional measuring method is compared, the error measuring numerical value is contracted to the modified value error of laser range finder own by about 20mm, numerical value contrast is recorded by steel tape mensuration and laser range finder method, crane span is at more than 34.5m, and steel tape mensuration is not tool measurement requirement;
Seamless Tube Plant of Baotou Steel Corp. φ 460 unit crane rail is apart from the use 14 months through this measuring method, remarkable effect is served to the Adjustment precision of gauge, namely crane locomotive rotation browsing rail phenomenon is thoroughly solved, simultaneously not more wheel change, not only reduce the workload of survey crew, and in measuring process, do not affect produced on-site operating rate, also reduce standby redundancy expense.
Below in conjunction with accompanying drawing, the invention will be further described.

Embodiment
Below in conjunction with drawings and Examples, to above-mentioned being described in more detail with other technical characteristic and advantage of the present invention.
A kind of overhead travelling crane span measurement mechanism as shown in Figure 2, described measurement mechanism comprises 2mm steel plate and to be welded housing 1 and reflecting plate 6, housing 1 open top, inside is provided with laser range finder 3, both sides, below are welded with the thick bottom plate of 2mm 2 respectively, wherein side bottom plate 2 is provided with and regulates trapped orbit screw rod 5, and housing 1 sidewall corresponding above it is provided with laser range finder and regulates standing screw 4, the laser reflection return laser light stadimeter 3 of reflecting plate 6 for being launched by laser range finder 3.
Laser range finder 3 is put into housing 1, tightening laser range finder regulates standing screw 4 to tighten laser range finder 3, it is made to eliminate the play error with housing 1, again housing 1 is placed on crane runway 7 wherein on a row rail level (laser range finder 3 surface of emission with inside track 8 parallel), the adjustment of laser range finder 3 device and track, fastening, according to laser range finder surveyor's staff, trapped orbit screw rod 5 is regulated to tighten by bottom of device, to make inside device and laser range finder 3 and track 8 fastening and be in horizontality, again by 9 setting reflecting plates 6 outside another row track, the distance of laser beam 10 pairs of reflecting plates 11 is utilized to measure (see Fig. 3) during last laser range finder 3, draw gauge 11 thus.
Laser range finder self round-off error is ± 2mm, record numerical value without the need to correction of tabling look-up, laser range finder is not namely by influence of temperature change, the personal safety of survey crew is also ensured to some extent, do not affect on-the-spot normal production simultaneously, field working conditions does not affect the error measuring numerical value, and Fig. 4 measures numerical value comparison diagram for adopting steel tape method to measure numerical value with adopting measurement mechanism of the present invention, can find out that adopting this device to carry out measurement span accuracy provides greatly.。
Above-described embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determines.
