Abstract
The utility model discloses a depth measuring device for a rotary drilling machine, which comprises a programmable controller, a display, two proximity switches and an induction plate. The induction plate is arranged on the side face of a main hoist; the two proximity switches are fixed on the supporting frame of the main hoist on the side face of the induction plate; and the programmable controller and the display are connected with the two proximity switches. The coaxial induction plate on the side face of the main hoist is detected directly through the two proximity switches, thereby achieving the process of always retracting steel wires along with the main hoist during the detection process. The depth measuring device has the advantages of high detection accuracy, accurate and effective detection, reasonable structure, stable performance, stability and reliability, uneasy deformation and less effect caused by external factors.
Description
Technical field
The utility model relates to the rotary drilling rig that uses in a kind of engineering construction, particularly a kind of depth measurement device that is used on the rotary drilling rig.
Background technology
Rotary drilling rig is the efficient pore-forming equipment of heavy caliber that uses in a kind of foundation construction, and the drilling rod that its utilization remains vertical direction directly rotates, excavates ground, thereby forms the stake hole of the required diameter and the degree of depth fast on ground.Rotary drilling rig is because power is big, power is strong, pore-forming is quick, so in the foundation construction process of the engineering of being widely used in, building.Existing rotary drilling rig in use owing to need to grasp at any time the degree of depth of boring, all is equipped with measurement mechanism on the gooseneck boom pulley of mast top, by gathering the rotating cycle of gooseneck boom pulley, converse the distance that wire rope is passed by, thereby determine the degree of depth in a hole.But the method for this detection gooseneck boom pulley rotating cycle in actual use, owing to be subjected to the bigger unit head of power and weight and the percussion of drilling rod, be easy to starting and operation produces skidding when stopping, thereby caused the measure error of stake hole depth, can not accurately guarantee the degree of depth in a hole; Simultaneously, the gooseneck boom pulley is subjected to that wire rope pressure is big, serious wear, and the distortion of the pulley yoke in the long-term work process, the capital makes measuring process produce cumulative errors and measurement is used near the switch performance instability, the stake hole depth can not get effective assurance, brings adverse effect for the use of rotary drilling rig, how to overcome the problem that this metering system runs in actual use, effectively guaranteeing the degree of accuracy of measurement, is problem to be solved in the utility model.
Summary of the invention
In view of above-mentioned deficiency of the prior art, the utility model aims to provide a kind of accuracy of measurement height, be subjected to extraneous factor to influence the depth measurement device that is used on the rotary drilling rig little, stable and reliable for performance.
The utility model is achieved through the following technical solutions:
A kind of depth measurement device that is used on the rotary drilling rig, comprise that programmable logic controller, display, two are near switch and tablet, tablet is located at the master winch side, on two are fixed on the tablet side near switch the master winch support, programmable logic controller and display and two are connected near switch.
Described tablet is provided with continuous dentate stripe, and two corresponding with dentate stripe respectively near switch.
Described tablet is circular, and tablet is coaxial with master winch, and dentate stripe is positioned on the circumference of tablet.
The depth measurement device that is used on the rotary drilling rig described in the utility model, by two coaxial inductive plates near switch direct detection master winch side, when having avoided surveying the gooseneck boom pulley before, because the shortcoming that detecting error is big, the degree of accuracy is low that the gooseneck boom pulley skids and causes, realized detection process all the time along with the process of master winch folding and unfolding wire rope is carried out, have the detection accuracy height, survey accurate and effective, rational in infrastructure, stable performance, solid and reliable, not yielding, be subjected to extraneous factor to influence little advantage.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Be further described below in conjunction with 1 pair of the utility model of accompanying drawing:
A kind of depth measurement device that is used on the rotary drilling rig described in the utility model, comprise programmable logic controller 6, display 7, two near switch 5 and tablet 3, wherein tablet 3 is circular, tablet 3 circumference are provided with the dentate stripe of continuous distributed, tablet 3 and master winch 4 are coaxial, tablet 3 is positioned at master winch 4 sides, tablet 3 is rotation simultaneously along with the rotation of master winch 4, on two are fixed on tablet 3 sides near switch 5 the master winch support 8, master winch support 8 is fixed on the mast 1, detecting head near switch 5 is corresponding with dentate stripe respectively, and programmable logic controller 6 and display 7 and two are connected by cable near switch 5.When master winch 4 rotations, tablet 3 is rotation thereupon also, two obtain corresponding two bars curves near switch 5 by the detection sensor to dentate stripe and show in display 7, programmable logic controller 6 can draw the length that wire rope 2 moves by judging and calculating, and by the contrast to two bars curve waveforms, programmable logic controller 6 readily appreciates that also master winch 4 is to promote drilling rod or transferring drilling rod, thereby obtains length information and demonstration on display 7 accurately.The operation conditions of direct detection master winch 4 like this, in the time of can effectively avoiding surveying the gooseneck boom pulley originally because the shortcoming that certainty of measurement is inaccurate, error is bigger that the gooseneck boom pulley skids and causes, have survey accurately, stable performance, advantage reliably.Certainly, when calculating the length of wire rope 2 operations by the quantity of dentate stripe on the detection sensor plate 3, the factors such as original position that also need wire rope 2 on the change in length of master winch 4 lay winding wire ropes 2 in the thickness of corresponding consideration wire rope 2, the every circle rotary course and the master winch 4, and these all can be finished by corresponding process software in the programmable logic controller 6 and are provided with and compensation, finish the process of digging of revolving thereby finally draw accurately length information with auxiliary rotary drilling rig.
Claims (3)
1, a kind of depth measurement device that is used on the rotary drilling rig, it is characterized in that, comprise programmable logic controller, display, two described tablet is located at the master winch side near switch and tablet, on two are fixed on the tablet side near switch the master winch support; Described programmable logic controller and display and two are connected near switch.
2, the depth measurement device that is used on the rotary drilling rig according to claim 1 is characterized in that, described tablet is provided with continuous dentate stripe, and two corresponding with dentate stripe respectively near switch.
