Description

Technical Field

[0001] This utility model relates to the technical field of blast hole cleaning equipment, and in particular to a blast hole cleaning device with force measuring function. Background Technology

[0002] In operations involving boreholes, especially in blasting operations, it is essential to detect and clean the borehole before loading emulsion explosives into it. This involves determining whether the borehole has collapsed or become blocked due to complex geological conditions and removing debris and other contaminants. If this step is omitted or improperly performed, it can easily lead to the failure of the borehole or damage to the emulsion explosives during loading, resulting in safety hazards.

[0003] In existing technologies, borehole exploration and cleaning operations mostly rely on manual labor, requiring workers to use hand tools to penetrate deep into the borehole for exploration and cleaning. However, blasting operations are often carried out in complex geological conditions and harsh environments. Manual operation is not only labor-intensive and involves complicated procedures, but also poses extremely high safety risks and is inefficient. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a borehole probing and cleaning device with force measurement function. This device probes and cleans the inside of holes, especially during blasting operations. Before loading emulsion explosives into blasting holes, the blasting holes must be probed and cleaned to determine whether they have collapsed or become blocked, and to remove debris from the holes to prevent the blasting holes from becoming ineffective or the emulsion explosives from breaking.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: A hole cleaning device with force measurement function includes a mounting base plate, a take-up and discharge turntable, a take-up and discharge force measurement mechanism, a hole balancing drive mechanism, a hole cleaning hose, a positive and negative pressure interface, a force measurement guide mechanism, and a hole cleaning probe. The mounting base plate is equipped with a take-up and discharge turntable and a force measuring and guiding mechanism. The take-up and discharge force measuring mechanism drives the take-up and discharge turntable, on which a hole cleaning tube is wound. One end of the hole cleaning tube is fixed to the positive and negative pressure interface, and the other end is equipped with a hole cleaning probe that passes through the force measuring and guiding mechanism. The hole balancing drive mechanism drives the force measuring and guiding mechanism. Under the coordinated action of the take-up and discharge turntable and the force measuring and guiding mechanism, the hole cleaning tube can drive the hole cleaning probe to make telescopic movements within the hole.

[0006] Preferably, the receiving and discharging turntable is rotatably mounted on one end of the mounting base plate, and the receiving and discharging force measuring mechanism is fixedly mounted on one end of the mounting base plate, driving the receiving and discharging turntable to rotate through gear transmission.

[0007] Preferably, the force measuring and guiding mechanism includes a mounting frame, a hanging rail is fixedly mounted on the front side of the mounting frame, a pair of hangers are mounted on the front side of the hanging rail, a driving wheel and an adjustable driven wheel are rotatably connected to the front side of the hangers, and the borehole balancing drive mechanism is mounted on the rear side of the mounting frame, and its output end drives the driving wheel to rotate.

[0008] Preferably, a force measuring device is also installed on the front side of the mounting bracket corresponding to the drive wheel. The force measuring device is a pressure sensor used to monitor the pressure of the cleaning hose in the hole.

[0009] Preferably, a bolt adjustment assembly is installed at the bottom of the hanger, the bolt adjustment assembly including an adjusting bolt and a locking nut, for adjusting the tension of the driven wheel.

[0010] Preferably, the force measuring and guiding mechanism further includes two pairs of auxiliary wheels, which are rotatably connected to the front and rear ends of the mounting frame, respectively. The cleaning hose passes through the guide channel formed by the two pairs of auxiliary wheels, the driving wheel, and the driven wheel in sequence.

[0011] Preferably, a docking plate is installed at the center of the receiving and discharging turntable. The docking plate is provided with a sealing interface. The cleaning hose passes through the sealing interface of the docking plate and is sealed to the positive and negative pressure interface. The positive and negative pressure interface can be selectively connected to a negative pressure air source or a positive pressure air source. The negative pressure state is used to adsorb debris in the hole, and the positive pressure state is used to blow away stubborn impurities.

[0012] Preferably, the hole-clearing probe is a camera, which can transmit data and display video footage inside the hole.

[0013] Preferably, the probe balance drive mechanism is a servo motor, and the take-up and discharge force measuring mechanism includes a drive motor and a torque sensor. The torque sensor is connected to the output end of the drive motor and is used to monitor the winding torque of the take-up and discharge turntable.

[0014] This utility model also provides a method for using a borehole cleaning probe with force measuring function, including the following steps: S1. Equipment preparation and positioning: Move the device to the side of the blast hole, fix it with the bottom support feet or lock it with the casters to ensure that the device is parallel to the axis of the blast hole; connect the positive and negative pressure interfaces to the negative pressure air source, and connect the external display screen to the hole cleaning probe, force measuring device and torque sensor to complete the equipment debugging.

[0015] S2. Hole Probing and Cleaning Operations: Activate the force-measuring mechanism and the hole-balancing drive mechanism, set the extension speed to 0.2-0.3 m / s, and drive the cleaning hose to slowly extend the cleaning probe into the blast hole. The cleaning probe provides real-time video feedback of the hole, allowing operators to determine the location and extent of blockage through the display screen. The pressure sensor of the force-measuring device monitors the radial pressure of the hose, and the torque sensor of the force-measuring mechanism monitors the winding torque. When the pressure value exceeds the limit, the device automatically reduces the extension speed and makes reverse fine adjustments to prevent the hose from bending or the probe from being damaged. Simultaneously, the extension and retraction of the cleaning hose pushes and pulls the debris, and the negative pressure airflow discharges the debris through the cleaning hose.

[0016] S3. Finishing Operation: After the hole cleaning probe confirms that there is no obvious blockage in the hole and the debris has been cleaned, stop the negative pressure adsorption; switch the positive and negative pressure interfaces to positive pressure air source, maintain positive pressure blowing for 3-5 seconds, and clean the residual debris in the hole cleaning hose; then reverse the drive of the retraction and discharge turntable to retract the hole cleaning hose at a speed of 0.3-0.5m / s, completing a single hole probing and cleaning operation.

[0017] The beneficial effects of this utility model are as follows: 1. It can replace manual exploratory hole cleaning operations, reduce labor intensity and safety hazards, adapt to complex and harsh blasting construction environments, and improve operational safety; 2. Integrated force measurement function: Through dual monitoring by force measuring device and torque sensor, the force situation inside the hole can be accurately grasped, avoiding damage to the probe and hose, and at the same time assisting in judging the degree of hole blockage; 3. High degree of automation: The rotating disc for receiving and discharging, along with the force-measuring and guiding mechanism, works together to enable the cleaning hose to extend and retract smoothly within the hole, pushing and pulling away debris to facilitate cleaning. Combined with positive and negative pressure adsorption and blowing functions, it improves cleaning efficiency and simplifies construction procedures. 4. The structure is compact, easy to install and debug, and can be adapted to blasting holes of different diameters. It has strong versatility and reduces construction and production costs.

[0024] Mounting base plate 1 is a rigid flat plate structure with four lockable casters at the bottom for easy movement and positioning of the device. Mounting base plate 1 is equipped with a take-up and discharge turntable 2 and a force measuring and guiding mechanism 7.

Its output end drives the take-up and discharge turntable 2 to rotate through a gear transmission with a transmission ratio of 1:4, ensuring smooth rotation of the turntable.

[0025] A cleaning hose 5 is wound around the discharge turntable 2. One end of the cleaning hose 5 is fixed to the positive and negative pressure interface 6, and the other end is equipped with a cleaning probe 8 that passes through a force-measuring guide mechanism 7. The force-measuring guide mechanism 7 includes a mounting frame 78. A hanging rail 71 is fixedly mounted on the front side of the mounting frame 78. A pair of hangers 72 are mounted on the front side of the hanging rail 71. A drive wheel 73 and an adjustable driven wheel 74 are rotatably connected to the front side of the hangers 72. A probe balancing drive mechanism 4 is installed on the rear side of the mounting frame 78, and its output end drives the drive wheel 73 to rotate. Furthermore, the force measuring and guiding mechanism 7 also includes two pairs of auxiliary wheels 76, which are rotatably connected to the front and rear ends of the mounting frame 78 respectively. The cleaning hose 5 passes through the guide channel formed by the two pairs of auxiliary wheels 76, the driving wheel 73 and the driven wheel 74 in sequence to realize bidirectional guidance and limiting of the hose and prevent the hose from deviating.

[0026] A force measuring device 77 is also installed on the front side of the mounting bracket 78, corresponding to the drive wheel 73. The force measuring device 77 is a pressure sensor used to monitor the pressure of the cleaning hose 5 in the hole.

[0027] Furthermore, a bolt adjustment assembly 75 is installed at the bottom of the hanger 72. The bolt adjustment assembly 75 includes an adjustment bolt and a locking nut. The adjustment stroke of the adjustment bolt is 0-20mm. By rotating the adjustment bolt, the height of the driven wheel 74 can be precisely adjusted, thereby adjusting the distance between the driven wheel 74 and the driving wheel 73, and realizing the tension adjustment of the cleaning hose 5.

[0028] A docking plate 21 is installed at the center of the receiving and discharging turntable 2. The docking plate 21 is equipped with a sealing interface. The cleaning tube 5 passes through the sealing interface of the docking plate 21 and is sealed to the positive and negative pressure interface 6. The positive and negative pressure interface 6 can be selectively connected to a negative pressure air source or a positive pressure air source. The negative pressure state is used to adsorb debris in the hole, and the positive pressure state is used to blow away stubborn impurities.

Under the coordinated action of the discharge turntable 2 and the force measuring and guiding mechanism 7, the hole cleaning hose 5 drives the hole cleaning probe 8 to make telescopic movements in the hole.

[0031] Work process: Move the device to the blast hole and fix it with the bottom support feet or the moving wheels to ensure that the device is parallel to the axis of the blast hole; connect the positive and negative pressure interface 6 to the negative pressure air source, and connect the external display screen to the hole cleaning probe 8, the force measuring device 77 and the torque sensor signal to complete the equipment debugging.

[0032] The force-measuring mechanism 3 and the probe balance drive mechanism 4 are activated, and the extension speed is set to 0.2-0.3 m / s. The cleaning hose 5 is driven to slowly extend the cleaning probe 8 into the blast hole. The cleaning probe 8 provides real-time video feedback of the hole, and the operator can judge the location and degree of blockage in the hole through the display screen. The pressure sensor of the force measuring device 77 monitors the radial pressure of the hose, and the torque sensor of the force-measuring mechanism 3 monitors the winding torque. When the pressure value exceeds the limit, the device automatically reduces the extension speed and makes a reverse fine adjustment to avoid hose bending or probe damage. At the same time, the debris is pushed and pulled by the extension and retraction of the cleaning hose 5, and the debris is discharged through the cleaning hose 5 in conjunction with the negative pressure airflow.

[0033] Once the hole cleaning probe 8 confirms that there is no obvious blockage in the hole and that the debris has been cleaned, stop the negative pressure adsorption; switch the positive and negative pressure interface 6 to a positive pressure air source, maintain positive pressure blowing for 3-5 seconds, and clean the residual debris in the hole cleaning hose 5; then reverse the drive of the retractable and discharge turntable 2 to retract the hole cleaning hose 5 at a speed of 0.3-0.5 m / s, completing a single hole probing and cleaning operation.
