Description

Technical Field

[0001] The present invention relates to the technical field of rock blasting, in particular to a blast hole detection device and method for rock blasting. Background Art

[0002] Blasting is currently the most widely used and effective means of breaking rocks. During the blasting process, holes need to be drilled into the rock formation so that explosives can be loaded into the rock formation.

[0003] In the prior art, when conducting blasting hole detection, it is usually necessary to first detect the hole depth with a side depth meter, and then detect the collapsed hole on the inner wall of the hole with an ultrasonic hole wall detector. The working steps are cumbersome, resulting in low detection efficiency. At the same time, when a collapsed hole is detected, staff are often required to perform data analysis to determine the specific location of the collapsed hole, and then record the collapsed hole location to facilitate subsequent blasting work analysis. The convenience is insufficient. Therefore, there is a need for a device that can automatically detect the hole depth and the location of the collapsed hole on the inner wall of the hole, and record and analyze the collapsed hole location at the same time, so as to avoid low detection efficiency and insufficient convenience.

[0012] Preferably, the method for using the blast hole detection device for rock blasting comprises the following steps: S1: The staff first controls the electric push rod to drive the telescopic sleeve to extend and retract, so that the bearing platform enters the blasting hole and is located at the opening. Then, by manually toggling the control rod, the two locking wedge blocks are driven to move upward along the second spring telescopic rod through the curved connecting rod, so that they are away from the stop wedge blocks. The stop wedge blocks move under the action of the first spring telescopic rod with stored force, thereby driving the articulated frame to slide synchronously along the side end of the bearing platform. Then, under the cooperation of the first linkage rod, the second linkage rod and the matching rod, each control component is moved away from the bearing platform, and the side end of each induction wheel is made to contact the inner wall of the blasting hole. The position of the induction wheel is stabilized and will not deviate by the provided flexible spring sheet and the center rod. S2: Subsequently, under the action of the electric push rod, the bearing platform and the induction wheel move vertically downward along the blasting hole. When encountering a collapsed hole, the induction wheel slides along the inner wall to the collapsed hole. At the same time, the sliding frame slides in the limit frame, thereby driving the adjacent hinged frame to slide, and then pulling the position of the hinged frame to stretch the first spring telescopic rod, so that the recording component can record according to the moving distance, thereby determining the collapsed hole position, and when the induction wheel moves out of the collapsed hole, the first spring telescopic rod is driven to restore to the unlocked state through the first linkage rod, the second linkage rod and the matching rod, thereby synchronously recording the longitudinal distance of the collapsed hole, thereby facilitating subsequent data analysis and improving the convenience of using the device; S3: After the control locking wedge block moves away from the resisting wedge block, the resisting wedge block drives the synchronous L-shaped rod to move, thereby driving the two control clamping parts to clamp the side ends of the recording pen through the compression spring and the telescopic rod, so that the recording pen slides along the through-hole through the resisting ring under the action of the telescopic spring, so that its output end resists on the drawing and synchronously pulls the tension spring. At this time, under the extension of the telescopic sleeve, the telescopic toothed rod is driven to extend synchronously, thereby driving the linkage gear meshing with it to rotate, so that the mating gear rotates synchronously. Since the linkage gear and the mating gear have different diameters, the mating gear can be proportional to the extension distance of the telescopic toothed rod. It drives the cooperating toothed rod to move upward, thereby synchronously driving the polygonal paper holder to move upward through the connecting rod, thereby stretching the drawing and pulling it at one end of the recording pen, so that the recording pen draws lines according to the conditions of the inner wall of the blasting hole. When encountering a collapsed hole, the first spring telescopic rod stretches, thereby driving the recording holder to move through the synchronous L-shaped rod, thereby recording a curve of corresponding proportion on the drawing paper, and after passing through the collapsed hole, the first spring telescopic rod returns to the unlocked state, thereby driving the recording holder to move the recording pen back to the longitudinal line through the auxiliary telescopic rod, and after moving to the bottom, the rotating table is driven to deflect the bearing platform, and it moves upward after deflection, thereby detecting the undetected inner wall of the blasting hole.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, when the device is used, the driving component is controlled to work, thereby driving the identification device to enter the blasting hole, and the sensing end of the sensing component can be against the inner wall of the hole, and then the sensing component is moved to the bottom of the hole by the driving component. During the penetration process, the paper discharge component is driven to work synchronously, so that one end of the paper surface is against the recording end of the recording component, forming a longitudinal line corresponding to the blasting hole. When the collapsed hole position is detected, the recording component performs a corresponding proportional change according to the change of the sensing component, thereby recording a curve of the corresponding position on the paper surface, thereby facilitating the staff to analyze the collapsed hole position through the curve change position in the straight line on the drawing, and to perform data analysis on the collapsed hole according to the curve change rate. In this process, the need to detect the hole depth and the collapsed hole position of the inner wall of the blasting hole through multiple working steps is avoided, the working steps are simplified, and the working efficiency is improved. At the same time, the position of the collapsed hole can be directly reflected on the drawing, and the collapsed hole data can be analyzed according to the information on the drawing, thereby improving the convenience of work. In the present invention, by cooperating with the sensing assembly and the control assembly, when the carrier platform enters the blasting hole, the side end of each sensing wheel can be brought into contact with the inner wall of the blasting hole. When encountering a collapsed hole, the sensing wheel will slide along the inner wall to the collapsed hole, causing the first spring telescopic rod to stretch, making it easier for the recording assembly to record according to the moving distance, thereby determining the collapsed hole position, thereby facilitating subsequent data analysis and improving the convenience of using the device. In the present invention, through the coordinated use of components such as the identification device and the paper discharge assembly, the drawing and the recording assembly cooperate with each other to record the longitudinal line of the hole depth in equal proportion during detection, and when the hole collapses, the recording assembly records it in a curve on the drawing, which is convenient for subsequent data analysis of the collapsed hole, thereby avoiding the need to detect the hole depth and the position of the collapsed hole on the inner wall of the blasting hole through multiple working steps, simplifying the working steps, and thus improving work efficiency. At the same time, the position of the collapsed hole can be directly reflected on the drawing, and the collapsed hole data can be analyzed based on the information on the drawing, thereby improving convenience in work.

When encountering a collapsed hole, the first spring telescopic rod 332 stretches, thereby driving the recording frame 51 to move through the synchronous L-shaped rod 41, thereby recording a curve of corresponding proportion on the drawing paper, and after passing through the collapsed hole, the first spring telescopic rod 332 returns to the unlocked state, thereby driving the recording frame 51 to move the recording pen 54 back to the longitudinal line through the auxiliary telescopic rod 52, and after moving to the bottom, by driving the rotating table 1 to deflect the supporting platform 25, and move upward after deflection, thereby detecting the undetected inner wall of the blasting hole.
