Description
Technical field
The utility model relates to a kind of measurement mechanism, relates in particular to a kind of orbit measurement device.
Background technology
In order to guarantee that hoisting crane with good state operation, except the normal operation of hoisting crane body equipment, also must ensure track in good condition.It is the basis of the good running state of hoisting crane that the track of good straightness accuracy, rigidity and stability is arranged.When track is installed and overhaul, in order to measure the straightness accuracy of track, technical personnel is often at track 1 ' support rail beam equal intervals (as with per 20 meters spacing) welding angle steel reference block 4 ', and the wire of placement and parallel track, by measuring steel wire line and track adjust the straightness accuracy of track apart from a, as shown in Figure 1.
Fig. 2 has shown the structure of existing orbit measurement device.Wherein angle steel reference block 4 ' is to process and directly be welded on the support rail beam by angle steel, angle steel reference block 4 ' upper end has recess 3 ', wire 2 ' is installed in the recess 3 ', and fixed block 5 ' captives joint to tighten wire with wire 2 ' one end.
In above-mentioned orbit measurement device, the angle steel reference block be adopt position, theodolite set-point and directly be welded on the support rail joist steel structural.Because be subjected to the impact of workshop steel structure differential settlement, the support rail beam can be out of shape and displacement, in case deform or displacement, original reference block point position that arranges also can corresponding generation deviation.Therefore, before adjusting the track straightness accuracy, original reference block must be cut off at every turn in advance, then adopt theodolite to come set-point position and welding reference block to guarantee the straightness accuracy of wire.And when using transit survey, the driving in whole zone must withdraw from use at every turn, the vibration that is produced with the operation that prevents from driving a vehicle and affect the accuracy rate of transit survey.For example, for 300 meters long tracks, if per 20 meters arrange a reference block, just must weld 15 reference blocks, make the loaded down with trivial details and inefficiency of whole operating process.
The utility model content
The purpose of this utility model provides a kind of adjustable track linearity measurer, its should the Measurement accuracy track straightness accuracy, avoid the deviation that causes owing to the beam displacement of track support rail or distortion, this adjustable track linearity measurer also should satisfy the fast requirement of measuring speed in addition, thereby increases work efficiency.
To achieve these goals, the utility model provides a kind of adjustable track linearity measurer, and it comprises: a reference block, and this reference block is provided with a groove; One wire wore described groove; This adjustable track linearity measurer also comprises:
One wire set collar, it is sheathed on the described reference block, and an end of described wire is fixed on this wire set collar;
One screw mandrel, it is connected with described reference block, and the setting party of described screw mandrel is to vertical with the bearing of trend of wire;
One base, described reference block is provided thereon, and is connected slidably with it, and described screw mandrel drives reference block axis direction along screw mandrel on base and moves.
The described adjustable track linearity measurer of the technical program, it is mobile in the direction vertical with track to drive reference block by screw mandrel, thereby the position of quick adjustment reference block, overcome departing from of bench mark, and then the straightness accuracy of quick adjusting wire, satisfy the measurement requirement of track straightness accuracy.
Further, described base is provided with slide block, and described reference block is provided with corresponding chute, and this slide block can move along chute.
Further, also be fixed with a positioning block on the described screw mandrel, described base is provided with corresponding positioning groove, and this locating piece correspondence is located in the positioning groove.
Further, described screw mandrel also with side's feather joint.
Further, this uses novel described adjustable track linearity measurer also to comprise a base plate, and it is located at the below of described base, and captives joint with described base.
Compare with existing track linearity measurer, adjustable track linearity measurer described in the utility model can substitute the measurement mechanism of simple disposable to realize repeated multiple times use, cut off and repeat in the situation of welding sequence saving, the accurately measuring track straightness accuracy, and greatly shortened the time of adjusting the wire straightness accuracy, greatly improved the work efficiency of track straight line degree measurement.
