[0002] The electronic detonator uses an electronic control module to control the detonation process, can register and issue control codes in the cloud, is convenient to manage, and is safer. In addition, the electronic detonator uses a delay control method to achieve precise blasting, and has higher blasting efficiency. However, the superimposed vibration and impact of the blasting process can cause the electronic detonators located at the rear of the blasting sequence to have a risk of failure, and therefore it is necessary to test the stability of the electronic detonator under actual conditions.

[0003] At present, a commonly used method is to test at the blasting site, and to correct through on-site data feedback, but this method has limited times, long time consumption for general testing, and the need for targeted removal or secondary detonation of the dummy charge, which has certain danger.

DETAILED DESCRIPTION

[0043] The technical solutions in the application will be described in further detail below with reference to the drawings.

[0044] Please refer to Figure 1 The anti-shock and anti-impact simulation testing device for electronic detonators disclosed in the application is composed of a blasting pool 1, a moving cross beam 2, a first operation platform 31, a second operation platform 32, a drilling module 4, a first installation pipe 51, a second installation pipe 52, a stretcher 53 and an electric drill bit 6, etc. The blasting pool 1 is placed on a horizontal ground and has a space inside and an open top end. The blasting pool 1 is used to simulate the soil structure of a blasting site, that is, according to the soil parameters in the actual use scene of the electronic detonator to be tested, the parameters are reproduced in the blasting pool 1, so that the obtained parameters are more accurate.

[0045] The moving cross beam 2 is located above the blasting pool 1 and has two operation platforms installed thereon, i.e., the first operation platform 31 and the second operation platform 32. Both the first operation platform 31 and the second operation platform 32 can move on the moving cross beam 2. The first operation platform 31 is provided with the drilling module 4, which is used to drill a blasting hole in the soil sample in the blasting pool 1, and the blasting hole is used to place an explosive therein to simulate the explosion in the actual blasting process.

[0046] In one explosion process, the number of blasting holes can be one or multiple.

[0047] The second operation platform 32 is provided with the first installation pipe 51, the second installation pipe 52, the stretcher 53 and the electric drill bit 6, etc. The first installation pipe 51, the second installation pipe 52, the stretcher 53 and the electric drill bit 6, etc. are used to bury an electronic detonator or a sensor in the soil sample in the blasting pool 1. The electronic detonator is used to detect the stability of the electronic detonator in the explosion environment, and the sensor is used to collect the environmental parameters of the electronic detonator in the explosion environment.

[0048] The first end of the first installation pipe 51 is fixed to the second operation platform 32, and the second end is an open end. The first end of the second installation pipe 52 is a closed end, and the second end is an open end. The second installation pipe 52 can move towards or away from the first installation pipe 51 under the driving of the stretcher 53. When the second installation pipe 52 moves away from the first installation pipe 51, a gap will appear between the two installation pipes. When the second installation pipe 52 moves towards the first installation pipe 51 and abuts against the first installation pipe 51, the gap between the two installation pipes disappears.

[0049] The electric drill bit 6 is installed on the second operation platform 32 and is used to drill a hole in the soil sample in the blasting pool 1, so that the first installation pipe 51 and the second installation pipe 52 can enter the soil sample in the blasting pool 1. The electric drill bit 6 has a channel inside, and the second installation pipe 52 is located in the channel and can extend out of the channel.

[0050] In combination with a specific simulation test process, the first operation platform 31 moves on the moving beam 2, and when it moves to a specified position, the drilling module 4 installed on the first operation platform 31 starts to drill holes (forming explosion holes) on the soil sample in the explosion pool 1. The amount of explosive and the hole spacing are executed according to the set parameters. Please refer to Figures 2 to 4 .

[0051] In some possible implementations, a linear module is installed on the first operation platform 31, and the moving direction of the linear module is opposite to the moving direction of the first operation platform 31 on the moving beam 2. In this way, the holes can be arranged in the form of an MxN matrix, and M and N are both natural numbers greater than zero.

[0052] The second operation platform 32 moves on the moving beam 2 at the same time, and when it moves to a specified position, the electric drill 6 starts to drill holes in the soil sample in the explosion pool 1, and at the same time, the first installation pipe 51 and the second installation pipe 52 move into the holes (test holes) drilled by the electric drill 6.

[0053] After the electric drill 6 stops drilling, the first installation pipe 51 and the second installation pipe 52 stop moving at the same time. At this time, the electric drill 6 and the first installation pipe 51 start to move away from the second installation pipe 52, and the second installation pipe 52 remains stationary at the original position.

[0054] A gap appears between the first installation pipe 51 and the second installation pipe 52, and the electronic detonator or sensor located in the first installation pipe 51 is exposed. Then, the pre-buried explosive is detonated, and the stability of the electronic detonator can be tested or the environmental parameters of the environment in which the electronic detonator is located during the explosion process can be collected using the sensor.

[0055] The test of the electronic detonator has the following two kinds:

[0056] The first kind is to detonate the electronic detonator after the explosive is detonated, in order to determine whether the stability of the electronic detonator meets the requirements;

[0057] The second kind is to take out the electronic detonator after the explosive is detonated, and analyze the electronic detonator after disassembly, in order to determine whether the stability of the electronic detonator meets the requirements.

[0058] Considering the displacement of the electronic detonator during the explosion process, a rope can be used to fix the electronic detonator, and the two ends of the rope are fixed on the inner wall of the electronic detonator and the second installation pipe 52, respectively.

[0059] In the above, the first operation platform 31 and the second operation platform 32 both have lifting functions, which are realized by telescopic cylinders. In the structure of the first operation platform 31, the first operation platform 31 has a moving part and a lifting part, the moving part is installed on the moving cross beam 2, and the two ends of the telescopic cylinder are connected with the moving part and the lifting part respectively.

[0060] The linear module and the drilling module 4 are both installed on the lifting part.

[0061] Please refer to Figure 5 In the structure of the second operation platform 32, the second operation platform 32 has a moving part and a lifting part, the moving part is installed on the moving cross beam 2, and the two ends of the telescopic cylinder are connected with the moving part and the lifting part respectively.

[0062] The first mounting pipe 51 is fixedly installed on the lifting part and communicates with the hole on the lifting part or extends from the lifting part, so that the electronic detonator or the sensor can be directly placed into the first mounting pipe 51 after being connected with the wire harness.

[0063] Overall, the explosive burying point, burying density and explosion amount in the electronic detonator anti-shock and impact simulation test device provided by the application can be freely set, and the soil in the blasting pool 1 can be filled according to the actual blasting environment.

[0064] The automation degree and safety in the test process are also higher. For the test of the electronic detonator, the electronic detonator can be tested after the explosion of the explosive or tested after being taken out. For the sensor, it can also be automatically taken out from the blasting pool 1 after the test is completed.

[0065] Please refer to Figure 1 As a specific embodiment of the electronic detonator anti-shock and impact simulation test device provided by the application, the drilling module 4 is composed of a first driving member 41 and an electric drill bit 42, the first driving member 41 is installed on the first operation platform 31, and the electric drill bit 42 is installed on the telescopic end of the first driving member 41.

[0066] In some possible implementations, the first driving member 41 uses an electric hydraulic cylinder. During the punching process, the first driving member 41 can work or not work, which needs to be determined according to the punching depth.

[0067] Please refer to Figure 1 and Figure 5 As a specific embodiment of the electronic detonator anti-shock and impact simulation test device provided by the application, the stretcher 53 is composed of a second driving member 531 and a guide rod 532, the first end of the guide rod 532 is fixed on the second mounting pipe 52, and the second end extends into the first mounting pipe 51 and is connected with the second driving member 531.

[0068] The second driving member 531 is installed on the second operation platform 32, and in some possible implementations, the second driving member 531 uses a pneumatic cylinder or an electric cylinder.

[0069] It should be understood that during the process of the electric drill bit 6 rising and exposing the second installation pipe 52 from inside the electric drill bit 6, the second installation pipe 52 needs to be kept stationary, and at this time, the second driving member 531 needs to cooperate to push the guide rod 532 to extend from inside the first installation pipe 51, and the extension length of the guide rod 532 increases with the distance between the first installation pipe 51 and the second installation pipe 52, so as to ensure that the second installation pipe 52 is kept relatively stationary relative to the blasting pool 1.

[0070] Further, a guide groove or a guide channel is additionally arranged on the inner wall of the second installation pipe 52, and the second end of the guide rod 532 passes through the guide groove or the guide channel. The guide groove or the guide channel functions to guide the moving direction of the guide rod 532.

[0071] In some possible implementations, the guide rod 532 is composed of a rigid part and a flexible part, the rigid part of the guide rod 532 is connected with the second installation pipe 52, and the flexible part of the guide rod 532 is connected with the second driving member 531. The flexible part functions to isolate the vibration generated in the blasting process from causing damage to the moving beam 2, the second operation platform 32, and the accessories of the second operation platform 32.

[0072] It should be understood that the vibration generated in the blasting process is transmitted to the first installation pipe 51 through the second installation pipe 52 and the guide rod 532, and then to the second operation platform 32, and in frequent blasting processes, the transmitted vibration can cause damage to the above-mentioned components. Therefore, the flexible part is used in the present application to isolate the vibration.

[0073] The rigid part of the guide rod 532 can be made of a metal bar, and the flexible part of the guide rod 532 can be made of a flexible material such as a steel wire.

[0074] Please refer to Figure 1 and Figure 5 , as a specific embodiment of the anti-vibration and anti-impact simulation test device of the electronic detonator provided in the application, the electric drill bit 6 is composed of a pipe drill bit 61 and a driving motor 62, and the pipe drill bit 61 is rotationally connected with the second operation platform 32; the driving motor 62 is installed on the second operation platform 32 and connected with the pipe drill bit 61, and functions to drive the pipe drill bit 61 to rotate.

[0075] In some possible implementations, the first end of the pipe drill 61 is connected with the rotating base on the second operation platform 32, and the driving motor 62 drives the pipe drill 61 to rotate through a gear set. There is a gap between the pipe drill 61 and the first mounting pipe 51, and several positioning rings are arranged in the gap to reduce the shaking of the pipe drill 61 during rotation.

[0076] The material of the positioning ring is polytetrafluoroethylene or copper.

[0077] When the second mounting pipe 52 is retracted into the electric drill 6, the closed end of the second mounting pipe 52 closes or extends from the pipe drill 61. That is, the closed end of the second mounting pipe 52 can be used as a part of the head of the pipe drill 61, which can accelerate the drilling speed.

[0078] Further, the cross-sectional area of the second mounting pipe 52 tends to decrease in the direction away from the first mounting pipe 51.

[0079] It should be understood that the above-mentioned actions involved in the process can be realized by the controller 7. The first operation platform 31, the second operation platform 32, the stretcher 53, the first driving member 41, the electric drill 42, the second driving member 531, the pipe drill 61 and the driving motor 62 are all connected with the controller 7 to realize automatic actions.

[0080] Taking the first operation platform 31 as an example, the power for moving the first operation platform 31 is provided by a motor, and the control end of the motor is connected with the controller 7 through a control circuit. The controller 7 sends control instructions such as starting, stopping and forward / reverse rotation to the motor belonging to the first operation platform 31 through the control circuit.

[0081] Please refer to Figure 9 The controller 7 can be a CPU, a microprocessor, an ASIC, or one or more integrated circuits for executing programs for controlling the above-mentioned contents. The controller 7 mainly includes a CPU 701, a RAM 702, a ROM 703 and a system bus 704, wherein the CPU 701, the RAM 702 and the ROM 703 are all connected with the system bus 704. The control circuit for controlling the motor belonging to the first operation platform 31 is also connected with the system bus 704.

[0082] The embodiments of the specific implementation are the preferred embodiments of the present application, but do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
