Abstract
The utility model relates to a hole depth measuring device for a drilling machine, which comprises a pull rope type length sensor, wherein a pull rope type length sensor body is jointed and mounted on the drilling machine by using bolts to ensure immobilization; a pull rope head of the pull rope type length sensor is fixed on a power head; and a pull rope of the sensor is pulled out or retracted from the sensor body by the power head. The hole depth measuring device adopts the principle that when a winding haulage rope drives the power head to drive a drilling rod perpendicular to the ground all the time to tunnel the ground, the pull rope of the length sensor is hauled by the power head, and the sensor detects a variation value of the length of the pull rope, namely a height variation value of the power head, that is a hole depth value is measured. The hole depth measuring device has the advantages that the hole depth measuring device is simple in structure, and can measure the drilling depth of the drilling machine accurately in real time.
Description
Technical field
The utility model relates to a kind of rig, particularly relates to a kind of rig hole depth measurement mechanism.
Background technology
In pile foundation construction, very accurate to the dark requirement of stake, need us to grasp at any time drilling depth, perpendicular to the drilling rod on ground, projected depth is crept into to guarantee to reach accurately in ground all the time thereby the control elevator haulage cable of in time operating machines drives the unit head drive.There is at present following several commonplace drilling depth to measure way.
The first be with installation of sensors on the gooseneck boom pulley, the band movable pulley rotates when the steel cable sliding of traction power head, the momentum of walking that utilizes the revolution that slides and radius of gyration to calculate wire rope has also just obtained drilling depth.
When adopting said method, because there are relative sliding in pulley and wire rope, the drilling depth of utilizing the measurement pulley to obtain is incorrect.
The second be with installation of sensors on elevator, utilize elevator revolution and wire rope rotating radiuscope to calculate drilling depth.
When adopting said method; utilize the revolution of elevator and wire rope rotating radius calculation out numerical value and the momentum of walking of actual wire rope relatively meet; but when actual drilling rod is transferred, often can exist wire rope to transfer, but the situation that drilling rod does not descend.The drilling depth that shows under such state is also incorrect.
Therefore, the degree of accuracy that how to improve the drill hole of drilling machine depth survey is in the art problem demanding prompt solution
The utility model content
Technical problem to be solved in the utility model is can be in real time and measure accurately the rig hole depth measurement mechanism of the drill hole of drilling machine degree of depth.
In order to solve the problems of the technologies described above, the rig hole depth measurement mechanism that the utility model provides, the body of a dragline type linear transducer is fixedly mounted on rig, and the stay cord fag end of the sensor stay cord of described dragline type linear transducer is fixed on unit head.
The body of described dragline type linear transducer utilizes bolted on connection to be arranged on described rig.
Adopt the rig hole depth measurement mechanism of technique scheme, its operating principle is: the dragline type linear transducer is fixed on drilling machine body, the fag end of sensor stay cord is fixed on unit head, when thereby the elevator haulage cable drives unit head and drives all the time drilling rod perpendicular to ground ground is tunneled, the sensor stay cord of dragline type linear transducer is drawn by unit head, the change value that sensor the detects pulling rope length unit head height change value of killing has namely been measured the hole depth value.
In sum, the utility model is a kind of simple in structure, can be in real time and measure accurately the rig hole depth measurement mechanism of the drill hole of drilling machine degree of depth.
Description of drawings
The accompanying drawing that consists of a part of the present utility model is used to provide further understanding of the present utility model, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of improper restriction of the present utility model.
Fig. 1 is embodiment rig hole depth measurement mechanism schematic diagram.
Fig. 2 is the sensor construction schematic diagram.
The specific embodiment
Further illustrate the specific embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figures 1 and 2, the body 2-1 of dragline type linear transducer 2 utilizes bolted on connection to be arranged on rig 1 and maintains static with assurance, the stay cord fag end 2-3 of the sensor stay cord 2-2 of dragline type linear transducer 2 is fixed on unit head 3, and unit head 3 pulls sensor stay cord 2-2 or retracts from sensor body 2-1.
As shown in Figures 1 and 2, dragline type linear transducer 2 is fixed on rig 1 fuselage, the fag end 2-3 of sensor stay cord 2-2 is fixed on unit head 3, when thereby the elevator haulage cable drives unit head 3 and drives all the time drilling rod perpendicular to ground ground is tunneled, the sensor stay cord 2-2 of dragline type linear transducer 2 is drawn by unit head 3, the change value that dragline type linear transducer 2 detects the length of the sensor stay cord 2-2 unit head height change value of killing has namely been measured the hole depth value.
The above is only preferred embodiment of the present utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
