Abstract

The utility model relates to a drilling machine, and particularly to a control device for hole forming precision of the drilling machine. The measuring/controlling device for hole forming angle and depth of the drilling machine comprises a length calibrated scale and an angle dial disk. The length calibrated scale is parallel with a drilling rod and furthermore a zero position of the length calibrated scale is level with the top of the drilling rod. The angle dial disk is arranged at the middle part of the length calibrated scale, and is furthermore provided with a pointer which is hinged at the center. The pointer is vertically oriented to ground always. The measuring/controlling device for the hole forming angle and depth of the drilling machine has the following advantages: low cost, high convenience in mounting, and easy popularization.

Description

Rig becomes the measure and control device of orifice angle and the degree of depth

Technical field

The utility model relates to rig, relates in particular to the control device of pore-forming accuracy of drilling machine.

Background technology

At present, rig angle and degree of depth in pore forming process are often estimated definite by the rig driver, larger error occurs easily, in the high engineering of the accuracy requirements such as massif controlled blasting, the error of depth of pore forming and angle often causes serious consequence, and subsequent treatment can improve cost and delay the duration.Domestic more existing auxiliary rigs are adjusted to the device of orifice angle, for example " automatic mast angle adjustment device for core-drilling machine ", application number: 201010121811.9, this device forms by parts such as obliquity sensor, central processing unit, display screens, this device can be controlled the angle of drilling machine mast, but cost is higher, and the maintenance difficulty is difficult to promote the use of in construction.

Summary of the invention

The utility model is intended to overcome the defective of prior art, provides a kind of rig to become the measure and control device of orifice angle and the degree of depth.The utility model is with low cost, and is easy for installation, is easy to promote.

In order to solve the problems of the technologies described above, a kind of rig becomes the measure and control device of orifice angle and the degree of depth, it comprises a length rule and an angle dial, described length rule is parallel with drilling rod and its zero-bit is concordant with the drilling rod top, described angle dial is installed in length rule middle part, and with the pointer of a hinge joint at the center, this pointer is vertical directed towards ground all the time.

Material of the present utility model is stainless steel, aluminium alloy or irony, and pointer is all the time perpendicular to ground when the drill boom mast rotates, and the angle of pointer indication represents the angle of drilling rod and surface level.The utility model can the work of Effective Raise rig precision, improve construction quality, avoid because the adverse consequences that depth of pore forming and angular error cause, reduce project cost is saved the duration.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is the utility model synoptic diagram;

Fig. 2 is the enlarged drawing of angle dial.

Embodiment

As depicted in figs. 1 and 2,1 be that main body, 2 is for the length rule among the figure; 3 is angle dial; 4 is pointer; 5 is the drill boom mast; 6 is drilling rod.A kind of rig becomes the measure and control device of orifice angle and the degree of depth, it comprises a length rule 2 and an angle dial 3, described length rule and drilling rod 6 are parallel and its zero-bit is concordant with the drilling rod top, described angle dial is installed in length rule middle part, and with the pointer of a hinge joint at the center, this pointer is vertical directed towards ground all the time.Length of the present utility model is determined according to the length of drill boom mast, 0 °-90 ° of angle dial meter full scales, and minimum scale is 2 °, the angle of pointer indication represents the angle of drilling rod and surface level.

As shown in Figure 1, the length of supposing every drilling rod is a, and existing n root drilling rod pierces in the soil body, n+1 root drilling rod bottom rigidly connects when contacting the soil body, scale corresponding to top is b, and scale corresponding to drilling rod top is c when pore-forming is finished, then actual drilling depth L=n*a+c-b.In the middle of Fig. 2, the angle that pointer 4 points to is 64 °, and the angle of expression drilling rod and surface level is 64 °.

Claims

1. a rig becomes the measure and control device of orifice angle and the degree of depth, it is characterized in that, it comprises a length rule and an angle dial, described length rule is parallel with drilling rod and its zero-bit is concordant with the drilling rod top, described angle dial is installed in length rule middle part, and with the pointer of a hinge joint at the center, this pointer is vertical directed towards ground all the time.
