Technical Field

The utility model relates to a construction monitoring technology field relates to a drilling rod straightness detection device that hangs down especially.

Background

The perpendicularity deviation of the pile is required to be not more than 1% during CFG pile construction. Because the foundation soil is often uneven, the drill rod of the drilling machine is difficult to avoid skewing in the construction process. In order to ensure the perpendicularity of the CFG pile, attention needs to be paid to checking the perpendicularity of the rechecking drill rod at any time in the drilling process, and once the perpendicularity exceeds the limit or approaches the limit, the adjustment is carried out in time.

At present, three methods are mainly used for checking the verticality of a drill rod and judging whether the verticality exceeds the limit or not: firstly, a constructor observes the position of a drill rod by using a total station or a theodolite so as to judge whether the drill rod is vertical or not, and adjusts the drill rod when the drill rod is inclined greatly; secondly, a constructor visually observes the relative position of a plumb bob arranged on a drill rig guide frame connected with the drill rod and a horizontal contrast line drawn on the guide frame, so as to judge whether the drill rod is vertical or not, and adjusts when the drill rod is sensed to be inclined greatly; and thirdly, automatically acquiring the inclination angle data of the drill rod or the guide frame by using an instrument with an inclination angle sensor, and judging whether the drill rod is vertical or not by a constructor according to the specific numerical value or image display of the data on the instrument display screen, and adjusting when the constructor feels that the drill rod is inclined greatly.

the three methods are all to judge whether the drill rod is inclined to the degree required to be adjusted according to the subjective feeling of constructors, and a specially-assigned person needs to be dispatched to check in real time, so that time and labor are wasted, and the judgment precision is low.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

Fig. 1 shows the structure of the drill rod verticality detection device provided by the utility model. The device is including casing 1, biax angular transducer 2, singlechip 3, bee calling organ 4 and the LED lamp 5 that has magnetic chuck 6, biax angular transducer 2, singlechip 3 and bee calling organ 4 are located 1 inside the casing, LED lamp 5 is located on the casing 1, biax angular transducer 2, bee calling organ 4 and LED lamp 5 respectively with 3 electricity of singlechip are connected. The housing 1 is optionally square or circular; the double-shaft inclination angle sensor 2 is used for acquiring the inclination angle of the drill rod relative to the whole horizontal plane in real time in the drilling process. The single chip microcomputer 3 is used for comparing the inclination angle with a threshold value. The buzzer 4 is used for giving an audible alarm when the inclination angle is larger than a threshold value. The LED lamp 5 is used for emitting light to indicate the inclination direction when the inclination angle is larger than a threshold value. Further, the device also includes a power supply (not shown) for powering the components in the device. The power source comprises a rechargeable battery and/or a solar cell.

Fig. 2 shows a schematic rear view of a device for detecting the verticality of a drill rod according to the present invention. The example device is in the shape of a cube with a square front and back, and the magnetic chuck 6 is used to hold the device at any height above the drill pipe (above the pre-drilling depth) or on the guide rod of the drill pipe, preferably at the side of the device housing. Optionally, LED lamp 5 is including installing 8 lamp pearls that are circular arrangement at the casing back, works as when the device is vertical to be placed, wherein 2 lamp pearls are located the horizontal direction, show left and right respectively, 2 lamp pearls are located the vertical direction, show preceding and back respectively, 4 lamp pearls are located respectively and are 45 degrees four directions of angle with the horizontal direction, show left front, right front, left back, right back respectively, only can send light with 1 or 2 lamp pearls that the incline direction is unanimous to can clearly show the direction of slope. When the direction of slope corresponds with a certain lamp pearl instruction direction, this lamp pearl is luminous, and when the direction of slope was between the direction that two lamp pearls instructed, these two lamp pearls were luminous. The light emission means is, for example, blinking.
