Abstract
The utility model discloses a rotary drilling rig with a depth measurement function, which comprises a drilling rig platform, a main windlass mounted on the drilling rig platform, and a depth measurement device, wherein the depth measurement device comprises a sensor drive plate and sensors matched with the sensor drive plate; a mounting plate opposite to one end face of a reel of the main windlass is arranged on a rack of the main windlass; the sensor drive plate is coaxially fixed on the corresponding end face of the reel of the main windlass; the sensors are fixed at positions on the mounting plate, corresponding to drive plate teeth of the sensor drive plate; and the sensing ends of the sensors face towards the drive plate teeth corresponding to the sensors. The drilling depth of a drilling bucket has a direct relation with the displacement of a steel wire rope on the reel, no skid happens between the steel wire rope and the reel, and the sensor drive plate rotates with the reel, so that detection accuracy of the drilling depth is ensured. In addition, the main windlass is arranged on the drilling rig platform, and is lower, so that mounting and maintenance are convenient.
Description
Technical field
The utility model relates to a kind of rotary drilling rig with depth measurement function.
Background technology
Rotary drilling rig is the efficient pore-forming equipment of a kind of heavy caliber that uses in foundation construction, its utilization remains that the drilling rod of vertical direction directly rotates, excavates ground, thereby form fast the stake hole of required diameter and the degree of depth on ground, this rotary drilling rig is large due to power, power is strong, easy to use, the one-tenth piece is quick, so be widely used with in the foundation construction process of engineering construction.The boring procedure of rotary drilling rig is: drilling bucket is transferred, holed, and------turn round soil, close sluice gate---turned round hole, drilling bucket transferred and holed, so complete an operation cycle to mention drilling bucket.Because boring procedure is complicated, be not disposable boring, therefore need special checkout gear to measure drilling depth, to reach the requirement hole depth.
The sounding gear of existing rotary drilling rig comprises a sensor driver plate and two sensors, the sensor driver plate is the disk tooth, its structure as shown in Figure 1, comprise driver plate main body 21, the periphery of driver plate main body 21 has along its circumferential uniform driver plate tooth 211, the pulley coaxle on sensor driver plate and rotary digging driller mast top is connected, and two sensors are fixed on pulley yoke, and is oppositely arranged with two adjacent teeth of sensor driver plate respectively; Because the drilling bucket of rotary drilling rig is to be connected with the wire rope of winding on the main winch reel, wire rope also passes through pulley simultaneously, like this drilling bucket mention and the process transferred in, wire rope relies on sliding friction band movable pulley to rotate, the sensor driver plate rotates with pulley, the number of teeth that two sensors turns over by the measuring transducer driver plate calculates the degree of depth of boring after calculating by processor.There are the following problems for this form: 1, be positioned at the mast top of rotary drilling rig due to pulley, the position of whole sounding gear is too high, installation and maintenance inconvenience; 2, transfer in process at drilling bucket, easily skid between wire rope and pulley, two kinds of situations occur, a kind ofly be that pulley rotates but wire rope is moving, another kind is that wire rope moves but pulley is motionless, and both of these case all can cause fathoming not being inconsistent with actual value.
The utility model content
The purpose of this utility model is to provide a kind of rotary drilling rig that can Measurement accuracy drilling bucket drilling depth.
the utility model adopts following technical scheme: a kind of rotary drilling rig with depth measurement function, comprise drilling machine platform and be arranged on main winch on drilling machine platform, also comprise the sounding gear for detection of the drilling bucket drilling depth, sounding gear comprises sensor driver plate and the sensor that coordinates with the sensor driver plate, has the installing plate that an end face with the main winch reel is oppositely arranged on the frame of described main winch, described sensor driver plate is coaxial to be fixed on the corresponding end face of main winch reel, described sensor is fixed on the position corresponding with the driver plate tooth of sensor driver plate of described installing plate, and the induction end of sensor is towards its corresponding driver plate tooth.
Described sensor has two, and two sensors are oppositely arranged with wherein two adjacent driver plate teeth of sensor driver plate respectively.
Described two sensors are connected by bolt and described installing plate respectively.
Adopt the rotary drilling rig with depth measurement function of said structure, due to the coaxial end that is fixed on reel of the sensor driver plate of sounding gear, guaranteed that the sensor driver plate can rotate with reel, the sensor of sounding gear is fixed on installing plate, the induction end that has guaranteed sensor can be oppositely arranged with the driver plate tooth, has satisfied the needed correlated condition of whole sounding gear normal operation; The more important thing is, because the drilling depth of drilling bucket and the displacement of the wire rope on reel have direct relation, and do not have the phenomenon of skidding between wire rope and reel, add the upper sensor driver plate to rotate with reel, guaranteed the accuracy that drilling depth detects; In addition, main winch is arranged on drilling machine platform, and its position is relatively low, and installation and maintenance are also convenient.
Description of drawings
Fig. 1 is the structural representation of the sensor driver plate of existing sounding gear;
Fig. 2 is the main winch of a kind of embodiment of the present utility model and the assembling schematic diagram of sounding gear.
The specific embodiment
The utlity model has the embodiment of the rotary drilling rig of depth measurement function: as shown in Figure 2, comprise drilling machine platform (not shown), main winch and sounding gear, main winch is arranged on drilling machine platform, main winch comprises that frame and rotation are assemblied in the reel 1 on frame, is fixed with the installing plate 4 that an end with reel 1 is oppositely arranged on the frame of main winch; Sounding gear is prior art, comprise a sensor driver plate 2 and two sensors 3, the coaxial corresponding end that is fixed on reel 1 of sensor driver plate 2, two sensors 3 are bolted on respectively on installing plate 4 and are corresponding with wherein two adjacent driver plate teeth of sensor driver plate 2, and the induction end of two sensors 3 is respectively towards each self-corresponding driver plate tooth.
Because the drilling bucket of rotary drilling rig is to be connected with the wire rope of winding on reel, in the drilling bucket boring procedure, its drilling depth is directly relevant with the displacement of wire rope, the displacement of wire rope is relevant with the rotation of reel 1,2 of sensor driver plates rotate with reel 1, the number of teeth that two sensors 3 turns over by measuring transducer driver plate 2 calculates the degree of depth of boring after calculating by processor.Simultaneously, skidding can not occur between wire rope and reel, guarantee the accuracy of measuring.
In other embodiments, sensor also can be one or three, and is corresponding with one of them driver plate tooth when being one, when being three, corresponding respectively with three adjacent driver plate teeth.
