Description

Technical Field

[0001] This invention belongs to the field of tunnel blasting construction technology, and in particular relates to a circumferential rock drilling blasting device and construction method for tunnel blasting construction. Background Technology

[0002] In tunnel excavation, blasting is often required beforehand, with rock drilling and blasting being an important method. In actual rock drilling and blasting operations, multiple boreholes arranged in a circumferential pattern are typically opened on the blasting surface. Explosive charges are then prepared according to pre-designed blasting parameters, placed into the boreholes, and detonated to complete the blasting operation. Currently, during tunnel excavation and blasting, the positions of each blast hole are typically determined first using measuring tools. Then, manual drilling or chiseling equipment is used to manually drill the blast holes one by one in the surrounding rock. After the blast holes are drilled, pre-made explosive charges are manually placed into each hole. This process requires significant manpower and resources and is time-consuming, impacting the tunnel construction cycle. Existing patent CN201210509112.0 discloses a circumferential rock drilling blasting device for tunnel blasting. This patent can complete the drilling of multiple blast holes arranged in a circumferential pattern in one go, but it has certain limitations. The blast hole positions are relatively fixed, the positions cannot be adjusted, resulting in low flexibility. Furthermore, the device is prone to vibration during the drilling process, which can damage the equipment over time, and the drilling quality cannot be effectively guaranteed. Moreover, the blast hole drilling equipment is often in a humid environment, and the controller may experience partial discharge due to moisture or aging wiring. Existing controllers often lack discharge detection functions, and the sparks generated by the discharge can easily ignite the wiring, significantly increasing safety hazards. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a circumferential rock drilling and blasting device and construction method for tunnel blasting construction, which is reasonably designed, easy to use and operate, highly intelligent, and effective. It can automatically complete the opening of multiple blast holes arranged in a circumferential manner in one go, and can adjust the position of the opening to prevent the equipment from shaking during the opening process, thereby improving the quality of the opening.

[0004] One object of the present invention is to provide a circumferential rock drilling and blasting device for tunnel blasting construction.

[0005] The system includes a base, a first cylinder mounted on top of the base, a support mounted on top of the first cylinder, and an output shaft of the first cylinder connected to the lower surface of the support. The first cylinder is used to drive the lifting and lowering of the support. A rock-drilling ring is mounted on top of the support, and a drilling mechanism is mounted on the rock-drilling ring. The drilling mechanism includes a motor and a drill bit. The output shaft of the motor passes through the side wall of the rock-drilling ring, and the drill bit is connected to the output shaft of the motor. The motor is used to drive the drill bit to rotate, thereby realizing drilling operations. Support rods are mounted on both sides of the base. The support rods are inclined and hinged to the side walls of the base. A support assembly is mounted between the support rods and the base. The support assembly includes a second cylinder and a support rod. The second cylinder is mounted on the side wall of the base. The output shaft of the second cylinder is connected to one end of the support rod, and the other end of the support rod is connected to the side wall of the support rod. The second cylinder is used to drive the support rod to move left and right, thereby driving the support rod to move in the left and right direction, thus adjusting the angle between the support rod and the base. A pressure pump is also mounted on the base. The pressure pump is connected to the second cylinder through a connecting pipe. The pressure pump is used to adjust the pressure value in the second cylinder, thereby realizing the operation process of the second cylinder on the support rod. A pressure sensor is mounted on the lower end of the support rod. A controller is mounted on the base. The controller is electrically connected to the pressure pump, the first cylinder, the motor, and the pressure sensor.

[0006] When the support rod retracts along the top of the base, the pressure sensor retracts along with the support rod until it comes into contact with the ground. At this time, the pressure sensor generates a signal due to the pressure from the ground and transmits the signal to the controller. The controller recognizes the signal and controls the pressure pump to stop operating, thereby stopping the second cylinder from pushing the support rod and stabilizing the support rod on the base.

[0007] The base is provided with a pulley at its lower end, which facilitates the movement of the base. The pulley is provided with a brake pad to prevent the pulley from slipping during operation.

[0008] Optionally, a limiting mechanism is provided between the base and the support. The limiting mechanism includes a limiting cylinder disposed on the upper surface of the base and a limiting rod slidably disposed within the limiting cylinder. The upper end of the limiting rod is fixedly connected to the lower surface of the support.

[0009] Optionally, the drilling mechanism is configured as several groups, and the several groups of drilling mechanisms are evenly spaced apart.

[0010] Optionally, the controller is equipped with a processor, and the controller is electrically connected to the processor. The controller is also equipped with an ultrasonic module and a photosensitive module, which are electrically connected to the processor. The ultrasonic module can sense the sound wave conditions of the surrounding environment, and the photosensitive module can sense the photoelectric conditions of the surrounding environment. When used together, the ultrasonic module and the photosensitive module can sense whether there is a discharge phenomenon in the surrounding environment.

[0011] Optionally, the ultrasonic module includes an ultrasonic detection module, an ultrasonic data processing module, and a first transmission module. The output end of the ultrasonic detection module is connected to the input end of the ultrasonic data processing module, and the output end of the ultrasonic data processing module is connected to the first transmission module. The ultrasonic detection module is used to detect the sound wave conditions of the surrounding environment. The ultrasonic data processing module is used to determine whether the sound wave values ​​of the surrounding environment are normal based on the sound wave values ​​of the surrounding environment. The first transmission module is used to transmit the data generated by the ultrasonic data processing module to the processor.

[0012] Optionally, the photosensor module includes a photosensor detection module, a photosensor data processing module, and a second transmission module. The output terminal of the photosensor detection module is connected to the input terminal of the photosensor data processing module, and the output terminal of the photosensor data processing module is connected to the second transmission module. The photosensor detection module is used to detect the photoelectric status of the surrounding environment. The photosensor data processing module is used to determine whether the photoelectric status of the surrounding environment is normal based on the photoelectric status of the surrounding environment. The second transmission module is used to transmit the data generated by the photoelectric data processing module to the processor.

[0013] Optionally, an alarm is provided on the surface of the controller. The alarm is electrically connected to the processor. When the ultrasonic module and the photosensitive module sense a discharge phenomenon in the surrounding environment, the processor can control the alarm to ring as a reminder.

[0014] Optionally, another objective of the present invention is to provide a circumferential rock drilling and blasting construction method for tunnel blasting construction.

[0015] The method includes the following steps:

[0016] S1: According to the required blasting range, the controller controls the first cylinder to drive the drilling mechanism to the required position. When the drilling mechanism rises to the required position, the first cylinder closes.

[0017] S2: When the drilling mechanism rises to the required position, the controller controls the pressure pump to operate. The pressure pump extracts gas from the second cylinder through the connecting pipe, thereby reducing the pressure value of the second cylinder. The second cylinder drives the support rod to retract, and the pressure sensor retracts along with the support rod until it contacts the ground. At this time, the pressure sensor generates a signal due to the pressure from the ground and transmits the signal to the controller. The controller recognizes the signal and controls the pressure pump to stop operating, thereby stopping the second cylinder from pushing the support rod and stabilizing the support rod on the base.

[0018] S3: When the support rod stabilizes the base, the controller controls the motor to operate, and the motor drives the drill bit to rotate to realize the drilling operation;

[0019] S4: After drilling is completed, the controller drives the support rod and the first cylinder to reset, and then moves the base to a safe area through the pulley. Then, the through hole after drilling is manually filled with explosives to realize the blasting operation.

[0020] Beneficial effects of the invention

[0021] This invention is rationally designed, easy to use and operate, highly intelligent, and effective. It can automatically complete the opening of multiple circumferentially arranged boreholes in one go, and the position of the boreholes can be adjusted to improve the flexibility of the opening process and prevent equipment vibration during the opening process, thereby improving the quality of the opening. In addition, since the controller may experience partial discharge due to moisture or aging wires, accompanied by sound and light, this invention uses an ultrasonic module and a photosensitive module to sense whether there is a discharge phenomenon in the surrounding environment. This is used to detect whether the environment around the controller is safe and whether there are any sparks generated by the discharge that could endanger the equipment, greatly improving the safety of enterprise production.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example

[0030] like Figures 1-5 As shown, one object of the present invention is to provide a circumferential rock drilling and blasting device for tunnel blasting construction.

[0031] The system includes a base 1, a first cylinder 2 mounted on top of the base 1, a support 3 mounted above the first cylinder 2, and the output shaft of the first cylinder 2 connected to the lower surface of the support 3. The first cylinder 2 is used to drive the lifting and lowering of the support 3. A rock-drilling ring 4 is mounted above the support 3, and a drilling mechanism is mounted on the rock-drilling ring 4. The drilling mechanism includes a motor 5 and a drill bit. The output shaft of the motor 5 passes through the side wall of the rock-drilling ring 4, and the drill bit is connected to the output shaft of the motor 5. The motor 5 is used to drive the drill bit to rotate, thereby realizing drilling operations. Support rods 6 are mounted on both sides of the base 1. The support rods 6 are inclined and hinged to the side walls of the base 1. A support assembly is provided between the support rods 6 and the base 1. The support assembly includes a second cylinder 7 and a support rod 8. A cylinder 7 is mounted on the side wall of the base 1. The output shaft of the second cylinder 7 is connected to one end of the support rod 8, and the other end of the support rod 8 is connected to the side wall of the support rod 6. The second cylinder 7 is used to drive the support rod 8 to move left and right, thereby driving the support rod 6 to move in the left and right direction, thereby adjusting the angle between the support rod 6 and the base 1. A pressure pump 9 is also mounted on the base 1. The pressure pump 9 is connected to the second cylinder 7 through a connecting pipe 10. The pressure pump 9 is used to adjust the pressure value inside the second cylinder 7, thereby realizing the operation process of the second cylinder 7 on the support rod 6. A pressure sensor is mounted at the lower end of the support rod 6. A controller 11 is mounted on the base 1. The controller 11 is electrically connected to the pressure pump 9, the first cylinder 2, the motor 5, and the pressure sensor.

[0032] When the support rod 6 retracts along the top of the base 1, the pressure sensor retracts along with the support rod 6 until it comes into contact with the ground. At this time, the pressure sensor generates a signal due to the pressure from the ground and transmits the signal to the controller 11. The controller 11 recognizes the signal and controls the pressure pump 9 to stop working, thereby stopping the second cylinder 7 from pushing the support rod 6 and stabilizing the support rod 6 on the base 1.

[0033] The lower end of the base 1 is provided with a pulley 12, which facilitates the movement of the base 1. The pulley 12 is provided with a brake pad to prevent the pulley 12 from slipping during operation.

[0034] A limiting mechanism is provided between the base 1 and the support 3. The limiting mechanism includes a limiting cylinder 23 disposed on the upper surface of the base 1 and a limiting rod 24 slidably disposed in the limiting cylinder 23. The upper end of the limiting rod 24 is fixedly connected to the lower surface of the support 3. During the lifting and lowering process of the support 3, the limiting rod 24 moves along the limiting cylinder 23, thereby ensuring that the position of the drilling mechanism will not shift.

[0035] This invention is reasonably designed, easy to use and operate, highly intelligent, and effective. It can automatically complete the opening of multiple blast holes arranged in a ring at one time, and the position of the holes can be adjusted to improve the flexibility of the hole-opening process, prevent the equipment from shaking during the hole-opening process, and thus improve the quality of hole opening.

[0036] The controller 11 is equipped with a processor 13, and the controller 11 is electrically connected to the processor 13. The controller 11 is also equipped with an ultrasonic module 14 and a photosensor module 15, both electrically connected to the processor 13. The ultrasonic module 14 can sense the sound wave conditions of the surrounding environment, and the photosensor module 15 can sense the photoelectric conditions of the surrounding environment. The ultrasonic module 14 and the photosensor module 15 work together to detect whether there is a discharge phenomenon in the surrounding environment. The ultrasonic module 14 includes an ultrasonic detection module 16, an ultrasonic data processing module 17, and a first transmission module 18. The output terminal of the ultrasonic detection module 16 is connected to the input terminal of the ultrasonic data processing module 17, and the output terminal of the ultrasonic data processing module 17 is connected to the first transmission module 18. The ultrasonic detection module 16 is used to detect the sound wave conditions of the surrounding environment; the ultrasonic data processing module 17 is used to determine the sound level of the detected surrounding environment based on the sound wave values. The first transmission module 18 transmits the data generated by the ultrasonic data processing module 17 to the processor 13 to determine whether the wave value is normal. The photosensitive module 15 includes a photosensitive detection module 19, a photosensitive data processing module 20, and a second transmission module 21. The output terminal of the photosensitive detection module 19 is connected to the input terminal of the photosensitive data processing module 20, and the output terminal of the photosensitive data processing module 20 is connected to the second transmission module 21. The photosensitive detection module 19 is used to detect the photoelectric status of the surrounding environment. The photosensitive data processing module 20 determines whether the photoelectric status of the surrounding environment is normal based on the photoelectric status. The second transmission module 21 transmits the data generated by the photoelectric data processing module to the processor 13. An alarm is installed on the surface of the controller 11 and is electrically connected to the processor 13. When the ultrasonic module 14 and the photosensitive module 15 sense a discharge phenomenon in the surrounding environment, the processor 13 can control the alarm to sound.

[0037] Since the controller 11 may experience partial discharge due to moisture or aging wires, accompanied by sound and light, the present invention uses an ultrasonic module 14 and a photosensitive module 15 to sense whether there is a discharge phenomenon in the surrounding environment. This is used to detect whether the environment around the controller 11 is safe and whether there are any sparks caused by the discharge that could endanger the equipment, thus greatly improving the safety of enterprise production.

[0038] Another object of the present invention is to provide a circumferential rock drilling and blasting construction method for tunnel blasting construction.

[0039] The method includes the following steps:

[0040] S1: According to the required blasting range, the controller 11 controls the first cylinder 2 to drive the drilling mechanism to the required position. When the drilling mechanism rises to the required position, the first cylinder 2 is closed.

[0041] S2: When the drilling mechanism rises to the required position, the controller 11 controls the pressure pump 9 to operate. The pressure pump 9 extracts gas from the second cylinder 7 through the connecting pipe 10, thereby reducing the pressure value of the second cylinder 7. The second cylinder 7 drives the support rod 6 to retract. The pressure sensor retracts along with the support rod 6 until it comes into contact with the ground. At this time, the pressure sensor generates a signal due to the pressure from the ground and transmits the signal to the controller 11. The controller 11 recognizes the signal and controls the pressure pump 9 to stop operating, thereby stopping the second cylinder 7 from pushing the support rod 6 and stabilizing the support rod 6 on the base 1.

[0042] S3: When the support rod 6 stabilizes the base 1, the controller 11 controls the motor 5 to operate, and the motor 5 drives the drill bit to rotate to realize the drilling operation;

[0043] S4: After drilling is completed, the controller 11 drives the support rod 6 and the first cylinder 2 to reset, and then moves the base 1 to a safe area through the pulley 12. Then, the through hole after drilling is manually filled with explosives to realize the blasting operation.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
