Abstract
The utility model relates to a hole depth measuring device, which comprises a hole depth measuring rod, a sliding seat and a positioning cross rod. One end of the positioning cross rod is connected with the sliding seat, the sliding seat is sleeved on the hole depth measuring rod, and scale marks are arranged on the hole depth measuring rod and are perpendicular to the hole depth measuring rod. The hole depth measuring device is simple in structure, easy in processing and wide in application, the problem of detection of the hole depth of a blast hole in blasting operation can be solved, control of the hole depth of the blast hole is facilitated, blasting effects are improved, the negative influence of improper hole depth of the blast hole on the blasting effects is avoided, and blasting cost is reduced.
Description
Technical field
The utility model relates to the blasting technique field, relates in particular to a kind of hole depth measurement mechanism.
Background technology
Explosion is widely used in many-sides such as mining, water conservancy, highway, railway, urban construction, and demolition effect directly influences project progress and engineering cost etc., in engineering, plays a crucial role.Need on blasting operation face, bore many blast holes before the explosion, the explosive of in these holes, packing into then can be implemented explosion, but the normal too dark or too shallow demolition effect that influences because of blast hole in the blasting operation at present.
The utility model content
The utility model technical matters to be solved provides a kind of hole depth measurement mechanism simple in structure, easy to use.
For addressing the above problem, the described a kind of hole depth measurement mechanism of the utility model, it is characterized in that: this device comprises hole depth sounding rod, slide and location cross bar; One end of said location cross bar is connected with said slide, and this slide is sleeved on the said hole depth sounding rod; Said hole depth sounding rod is provided with scale, and perpendicular with said hole depth sounding rod.
Said slide is provided with slotted eye, and this slotted eye is positioned on the scale of said hole depth sounding rod.
Said hole depth sounding rod is a straight-bar.
The utility model compared with prior art has the following advantages:
1, because the hole depth sounding rod in the utility model is a straight-bar, and has enough rigidity, therefore, be different from and be usually used in the dark rope of gaging hole, avoided rope crooked in the hole easily, thereby caused the blast hole hole depth to measure inaccurate problem.
2, owing to location cross bar and slide in the utility model are connected; And has certain length; The location cross bar is attached on the blasting operation face when measuring the blast hole hole depth, thereby can accurately measure the blast hole hole depth, and the bottom, blast hole hole that makes same hole depth at grade.
3, the utility model is simple in structure, processing is simple and easy, easy to use, applied range can be applicable to open-air drill eye blasting, underground drill eye blasting etc.
Description of drawings
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model.
Among the figure: the cross bar 5-blasting operation face of 1-blast hole 2-hole depth sounding rod 3-slide 4-location.
Embodiment
As shown in Figure 1, a kind of hole depth measurement mechanism, this device comprise hole depth sounding rod 2, slide 3 and location cross bar 4.One end of location cross bar 4 is connected with slide 3, and this slide 3 is sleeved on the hole depth sounding rod 2; Hole depth sounding rod 2 is provided with scale, and perpendicular with hole depth sounding rod 2.
Wherein: slide 3 is provided with slotted eye, and this slotted eye is positioned on the scale of hole depth sounding rod 2.Hole depth sounding rod 2 is a straight-bar.
Embodiment 1 is in the open in the bench blasting; Hole depth sounding rod 2 is placed downward blast hole 1; Hole depth sounding rod 2 bottoms contact with at the bottom of blast hole 1 hole, and slip slide 3 is attached on the blasting operation face 5 the location cross bar 4 that links to each other with slide 3; So that all be at the bottom of each blast hole hole on the plane, this moment, the scale of slide 3 hole depth sounding rods of living in 2 positions was exactly blast hole 1 degree of depth.Ground is smooth after the explosion, and demolition effect is good and reduced cost.
