[0012] Preferably, the use method of the blasting hole detection device for rock blasting comprises the following steps:

[0013] S1: The staff first drives the telescopic sleeve to stretch and retract through the control of the electric push rod, so that the bearing table enters the blasting hole and is located at the opening, then the control lever is manually rotated to drive the two locking wedge blocks to move upwards along the second spring telescopic rod through the curved connecting rod, so that the locking wedge blocks move away from the abutting wedge blocks, the abutting wedge blocks move under the action of the force-stored first spring telescopic rod, so that the hinged frame moves along the side end of the bearing table, and then, under the cooperation of the first linkage rod, the second linkage rod and the matching rod, each control member moves away from the bearing table, and the side end of each induction wheel abuts against the inner wall of the blasting hole, and the position of the induction wheel is stable and cannot deviate through the flexible spring sheet and the center rod.

[0014] S2: Then, under the action of the electric push rod, the bearing table and the induction wheel move vertically downward along the blasting hole, when encountering a collapsed hole, the induction wheel will slide along the inner wall to the collapsed hole, at the same time, the sliding frame slides in the limiting frame, so as to drive the adjacent hinged frame to slide, thereby pulling the position of the hinged frame, so that the first spring telescopic rod is stretched, and the recording assembly can record the moving distance, so as to determine the position of the collapsed hole, and when the induction wheel moves out of the collapsed hole, the first spring telescopic rod is restored 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, so as to facilitate subsequent data analysis and improve the convenience of using the device.

[0015] 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.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 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.

[0018] 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.

[0019] 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.

[0043] In this embodiment, as shown in Figures 1 to 11 A method for using a blast hole detection device for rock blasting, comprising the following steps:

[0044] S1: the staff first controls the electric push rod 21 to work, thereby driving the telescopic sleeve 23 to expand and contract, so that the bearing table 25 enters the blasting hole and is located at the opening, and then the control rod 338 is manually rotated, thereby driving the two locking wedge blocks 336 to move upwards along the second spring telescopic rod 335 through the curved connecting rod 337, so that they are away from the abutting wedge block 333, the abutting wedge block 333 moves under the action of the force-stored first spring telescopic rod 332, thereby driving the hinged frame 311 to synchronously slide along the side end of the bearing table 25, and then under the cooperation of the first linkage rod 312, the second linkage rod 314 and the cooperation rod 317, each control member 313 moves away from the bearing table 25, and the side end of each induction wheel 318 abuts against the inner wall of the blasting hole, and the position of the induction wheel 318 is stable and cannot be deviated through the flexible spring sheet 319 and the center rod 320;

[0045] S2: then, under the action of the electric push rod 21, the bearing table 25 and the induction wheel 318 move vertically downwards along the blasting hole, when encountering the collapsed hole, the induction wheel 318 will slide along the inner wall to the collapsed hole, at the same time, the sliding frame 316 is arranged to slide in the limiting frame 315, thereby driving the adjacent hinged frame 311 to slide, thereby pulling the position of the hinged frame 311, so that the first spring telescopic rod 332 is stretched, the recording assembly 5 is convenient to record according to the moving distance, so as to determine the position of the collapsed hole, and when the induction wheel 318 moves out of the collapsed hole, the first spring telescopic rod 332 is driven to restore to the unlocked state through the first linkage rod 312, the second linkage rod 314 and the cooperation rod 317, thereby synchronously recording the longitudinal distance of the collapsed hole;

[0046] S3: After the control locking wedge block 336 moves away from the resisting wedge block 333, the resisting wedge block 333 drives the synchronous L-shaped rod 41 to move, thereby driving the two control clamping parts 44 to clamp the two control clamping parts 44 on the side ends of the recording pen 54 through the compression spring 45 and the telescopic rod 43, and through the synchronous L-shaped rod 41, the recording pen 54 slides along the through-hole 53 through the resisting ring 55 under the action of the telescopic spring 56, so that its output end resists on the drawing, and the tension spring is pulled synchronously. At this time, under the extension of the telescopic sleeve 23, the telescopic toothed rod 24 is driven to extend synchronously, thereby driving the linked gear 68 meshing with it to rotate, so that the mating gear 66 rotates synchronously. Since the linked gear 68 and the mating gear 66 have different diameters, the mating gear 66 can rotate according to the telescopic gear. The extended distance of the slot rod 24 drives the matching toothed slot rod 64 upward in proportion, thereby synchronously driving the polygonal paper holder 62 upward through the connecting rod 63, thereby stretching the drawing and pulling it at one end of the recording pen 54, so that the recording pen 54 draws lines according to the condition of the inner wall of the blasting hole. 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.
