Abstract
Description
Technical Field
[0001] The utility model relates to the field of engineering blasting, in particular to a device for measuring parameters of tunnel blasting blastholes. Background Art
[0002] When conducting tunnel excavation and blasting operations, the quality of blastholes is a key factor affecting the blasting effect. Since the tunnel is a limited space, only the face being excavated is a free face, and the rest are all wrapped by surrounding rocks. Therefore, when drilling blastholes, the types of blastholes in the tunnel blasting face are divided into: slot holes, auxiliary holes, and peripheral holes according to their functions. In the axial angle (along the direction of the tunnel): slot holes and auxiliary holes are mostly horizontal holes, and the peripheral holes have a slight upward angle toward the arch; in the lateral angle (perpendicular to the direction of the tunnel): slot holes are of two types: inclined drilling and vertical drilling, auxiliary holes are mostly vertical drilling, and the peripheral holes have a slight contour extrapolation angle on the left and right sides.
[0003] At present, the method of measuring the angle of blastholes is that the number of blastholes in a tunnel blasting is usually not measured or roughly estimated through the blasting sticks used for loading. There are also some devices that can measure the angle, but the measurement parameters are incomplete, usually only a single measurement data. Utility Model Content
[0004] The utility model aims to provide a device for measuring tunnel blasting blasthole parameters in view of the problem that the prior art lacks a device that can accurately and comprehensively measure the length, angle and slope of blastholes.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A device for measuring parameters of tunnel blasting blastholes comprises an angle measuring device and a length measuring device, wherein the length measuring device is detachably connected to the angle measuring device, the angle measuring device is provided with an inclination measuring device capable of measuring the axial angle of the blasthole, and the angle measuring device is provided with an angle measuring device capable of measuring the lateral angle of the blasthole.
[0007] The device for measuring the parameters of tunnel blasting blastholes realizes measurement of the depth of the excavated blastholes by setting a length measuring device, and the angle measuring device is provided with a slope measuring device and an angle measuring device, which can respectively measure the lateral angle and the axial angle of the blasthole, thereby providing a more efficient and comprehensive measurement method and simplifying the measurement process.
[0008] As a preferred embodiment of the present invention, a length scale is provided on the outer side of the length measuring device, and the length scale starts from an end away from the angle measuring device. To measure the depth of a blasthole, the length measuring device needs to be inserted into the blasthole, and then the depth is measured by the length scale provided on the outer side of the length measuring device. Since one end of the length measuring device is connected to the angle measuring device, the length scale needs to be taken from the end away from the angle measuring device as the origin.
[0009] As a preferred solution of the utility model, a connecting rod is provided at one end of the length measuring device close to the angle measuring device, and a connecting port is provided at one end of the angle measuring device. The connecting rod and the connecting port are provided to realize that the length measuring device can be detachably connected to the angle measuring device, and because the depth of the blasthole excavated in each construction is different, the measuring range of the length measuring device to be used is also different, so the length measuring device can be detachably connected to the angle measuring device so that the length measuring device of different lengths can be replaced as needed.
[0010] As a preferred embodiment of the present invention, the length measuring device includes at least one length section, one end of which is provided with a connecting rod, and the other end of which is provided with a connecting port. In order to further improve the practicality of the length measuring device, the length measuring device is configured to be composed of a plurality of length sections, which can effectively shorten the preparation time before the test and improve the measurement efficiency.
[0011] As a preferred embodiment of the present invention, the angle measuring device includes an angle ruler and an angle disk. One end of the angle ruler is rotatably connected to the center of the angle disk. The angle ruler and the angle disk cooperate with each other. By digging out the angle ruler and making it perpendicular to the palm face, the parameters can be read according to the scale on the angle disk to know the angle between the blasthole and the palm face, that is, the lateral angle.
[0012] As a preferred embodiment of the present invention, a scale line is arranged on the center line of the angle ruler, and an observation window is arranged at the connection between the angle ruler and the angle disk. The scale line is arranged to be able to read the lateral angle parameters of the blasthole more clearly; the arrangement of the observation window can avoid the scale on the angle disk being difficult to read due to obstruction, thereby causing measurement errors.
[0013] As a preferred solution of the utility model, the observation window is a transparent material component. The observation window is made of transparent material, which can not only cover the angle disk to protect it, ensuring that the angle disk can measure accurately, but also avoid obstruction that makes the scale on the angle disk difficult to read, thereby causing measurement errors.
[0014] As a preferred solution of the utility model, the outer contour of the angle ruler is in the shape of a capsule, and a finger-locking groove is provided on the angle ruler. The finger-locking groove is provided to facilitate the rotation of the angle ruler during use.
[0015] As a preferred solution of the present utility model, the cross-sectional shape of the angle measuring device is rectangular, circular or polygonal.
[0016] As a preferred solution of the present utility model, the cross-sectional shape of the length measuring device is circular.
[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:
[0018] The device for measuring the parameters of tunnel blasting blastholes realizes measurement of the depth of the excavated blastholes by setting a length measuring device, and the angle measuring device is provided with a slope measuring device and an angle measuring device, which can respectively measure the lateral angle and the axial angle of the blasthole, thereby providing a more efficient and comprehensive measurement method and simplifying the measurement process.
