Description
Technical Field
The utility model relates to a during the operation of blasting, measure the vibration measuring instrument of blasting vibration size, specifically be a sensor alignment device of blasting vibration measuring instrument.
Background
The blasting vibration meter is a vibration meter which is applied to blasting measurement engineering and is specially used for recording and analyzing blasting vibration data, and the instrument, a sensor and a data analysis system can form an intelligent test system. The vibration meter can be adapted to the special environment of the blasting site only by the advantages of small volume, light weight, high sensitivity, multiple functions, convenient use, high automation degree, large memory capacity, various data transmission interfaces and the like.
The blasting vibration measurement system comprises: and during blasting test, the blasting vibration meter is placed at a vibration test point, and the test points can be distributed in a large range on site. The blasting vibration meter automatically conditions and stores dynamic and static analog signals generated by the sensor (including speed, acceleration, pressure, strain, temperature and the like), and after the test is finished, the blasting vibration meter can directly communicate with a computer through a USB interface on the instrument, transmit data and perform further data analysis and processing by combining with matched software. According to different test requirements, different types of vibration testers can be selected. Before the blasting field test, a user can withdraw from the site only by starting acquisition after simple parameter setting, and when a seismic wave signal is transmitted, the vibration meter can automatically record the dynamic waveform of the whole seismic wave, convert the dynamic waveform into a digital signal for storage, and then can be connected with a desktop or notebook computer through a USB interface, and data processing and analysis are carried out by using matched software. In one blasting operation, only by aligning the measuring direction of the sensor (i.e. the X direction on the sensor) with the direction of the blasting source, the measured data can be accurate and effective. However, in the actual installation process, the sensor is difficult to be accurately aligned with the center of the explosion source, and the vibration measurement quality is seriously affected, so that a device capable of accurately aligning the sensor with the center of the explosion source is urgently needed.
SUMMERY OF THE UTILITY MODEL
In order to solve the alignment problem of sensor (the X direction of sensor promptly) and explosion source center, prevent to lead to the measuring accuracy not high because of aiming at the inaccuracy, the utility model provides a sensor aligning device of blasting vibrometer.
The utility model adopts the following technical scheme: the sensor is characterized in that a shell is arranged outside a cube sensor with the side length of 60mm, the color of the shell is red, the shell is made of PVC plastic, the shell is in a cuboid shape, and the length of the shell is 70mm, the width of the shell is 70mm, and the height of the shell is 22 mm. Fixing slot is connected on shell upper portion (highly being 70mm, the draw-in groove is the diameter 14mm semicircle, and the face is the matte in order to increase the friction), and fixing slot is parallel with cuboid shell both sides, and a laser pen is installed to fixing slot top, because the X direction is parallel with the both sides of sensor on the sensor, consequently is pressing back laser pen on the sensor with the shell parallel with the X direction of sensor, and shell, fixing slot and laser pen three form a whole.
The utility model has the characteristics of it is following:
1. the material and the manufacturing process are simple, the material can be recycled, and the cost is greatly reduced;
2. the use is convenient, and the expected engineering requirements can be easily met on site.
Drawings
Fig. 1 is a laser pen according to an embodiment of the present invention;
FIG. 2 is a main body of an embodiment of the present invention;
FIG. 3 shows a screw rod according to an embodiment of the present invention
In the figure, 1-a laser pen, 2-a fixed clamping groove, 3-a red shell, 4-a bolt hole and 5-a screw rod.
Detailed Description
Please refer to fig. 1, fig. 2, and fig. 3, which show the specific structure of the embodiment of the present invention: before the laser pen is used, the laser pen is pressed on the clamping groove, then the X direction on the sensor is distinguished, the laser pen is enabled to be parallel to the X direction (the side, parallel to the X direction, of the shell is aligned to the side, parallel to the X direction, of the sensor, the shell is squeezed and pressed on the sensor, then the shell and the sensor are fixed by screwing the screw rod, and after the shell and the sensor are connected, a plurality of parts form a firm whole. When the laser is used, the bottom of the sensor is completely bonded with a position to be detected in a gypsum coupling mode, the laser pen is opened, and when the laser is adjusted to irradiate the center of the explosion source, the sensor and the center of the explosion source are on the same straight line, and the alignment is accurate. Wherein, the shell has the guard action concurrently, prevents that the sensor from being destroyed by the blasting flyrock in the measurement process, and the red is then to provide visual striking.
