Description

Technical Field

[0001] The present invention relates to the technical field of digital electronic detonator testing, in particular to an impact device. Background Art

[0002] On September 17, 2018, Guizhou Province held a conference promoting intelligent manufacturing in the civil explosives industry, proposing a three-to-five-year plan to promote the use of digital electronic detonators and phase out conventional electric and noning cord detonators. Consequently, market demand for digital electronic detonators is expected to continue to grow. During the production process of digital electronic detonators, they need to undergo a series of performance tests. Since digital electronic detonators use electronic control modules to control the detonation process, testing the power loss of the capacitor set on the electronic control module after the electronic detonator is impacted is a key test - namely the electronic detonator impact test. The specific operation method is: the electronic detonator with a leg wire is impacted against an obstacle at high speed, and the leg wire of the electronic detonator is electrically connected to the initiator. An oscilloscope is used to follow the electronic detonator impact process and record the electronic detonator communication, capacitance, ignition and other related conditions. However, currently, the impact is mainly created manually. With the increase in the production of electronic detonators, the impact force of this collision test method is uncontrollable and time-consuming and labor-intensive. Therefore, current technology has not yet provided an impact test device that can be used to perform impact tests on electronic detonators to measure whether the capacitor provided by the supplier has good impact resistance, thereby avoiding a series of explosion refusal problems caused by poor capacitor impact resistance, rapid power loss, and lack of secondary charge storage.

DETAILED DESCRIPTION

[0027] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0028] The embodiment of the present invention provides a collision device, see Figure 1-10 The invention comprises a support frame 1, a rotating mechanism, and a collision blocking mechanism 5. The support frame 1 comprises a base 11 and a supporting component provided on the base 11. The collision blocking mechanism 5 is fixed to the base 11. The rotating mechanism is provided on the supporting component and is provided with a clamping structure 33 for clamping an electronic detonator 0 with a leg wire. The rotation of the rotating mechanism drives the electronic detonator 0 clamped by the clamping structure 33 to collide with the collision blocking mechanism 5. The impact equipment provided by the present invention is used for the impact test of the electronic detonator 0. During the test, the electronic detonator 0 with the foot line only needs to be clamped on the clamping structure 33 provided by the rotating mechanism. The rotating mechanism rotates and drives the electronic detonator 0 clamped by the clamping structure 33 to collide with the collision blocking mechanism. Before the rotational impact, the foot line of the electronic detonator 0 is electrically connected to the initiator, and an oscilloscope is used to follow up the rotation and impact process of the electronic detonator 0, and the communication, capacitance, ignition and other related conditions of the electronic detonator 0 during the impact process are recorded. Thus, the electronic detonator 0 is subjected to an impact test by the impact equipment to measure whether the anti-impact performance of the capacitor provided by the supplier is good, so as to avoid a series of explosion refusal problems caused by the electronic control module of the electronic detonator due to the poor anti-impact performance of the capacitor, such as fast power loss and no power storage after secondary charging.

[0029] Specifically, the support component includes a first support frame 12 and a second support frame 13, which are fixed on the base 11 of the support frame 1 at a distance, so that a rotation space is reserved between the first support frame 12 and the second support frame 13 for the rotation mechanism. The first support frame 12 and the second support frame 13 both include: a first support column 231, a second support column 232 and a crossbeam 233. The two ends of the crossbeam 233 are respectively fixed to the upper ends of the first support column 231 and the second support column 232, and the bottom ends of the first support column 231 and the second support column 232 are fixed to the base 11 of the support frame 1, and the collision blocking mechanism 5 fixed to the base 11 is located between the first support column 231 and the second support column 232 of the first support frame 12 or the second support frame 13. The rotation mechanism is fixed to the crossbeam 233 of the first support frame 12 and the second support frame 13.

[0030] The rotating mechanism in the embodiment of the present invention includes a motor 2 and a rotating component 3. The impact device also includes two rotating shaft mounting assemblies 6. The two rotating shaft mounting assemblies 6 are respectively fixed on the crossbeam 233 of the first support frame 12 and the second support frame 13. The motor 2 is fixed on the crossbeam 233 of the first support frame 12, and the rotating shaft 21 of the motor 2 is rotatably connected across the first support frame 12 and the second support frame 13 through the two rotating shaft mounting assemblies 6. Specifically, the motor 2 in the embodiment of the present invention is fixed to the first support frame 12 by a motor fixing frame 8. For the specific structure of the motor fixing frame 8 provided in the embodiment of the present invention, please refer to Figure 10. Before the collision test of the electronic detonator 0 is carried out, the rotation speed of the motor 2 can be set according to the actual collision requirements to obtain the force required for the collision. Therefore, the collision force of the collision device provided by this embodiment is controllable, the test process has a high degree of automation, and is time-saving and labor-saving. The rotating component 3 is fixed on the rotating shaft 21 of the motor 2 and is located between the first support frame 12 and the second support frame 13 (that is, located in the rotation space reserved between the first support frame 12 and the second support frame 13), and the clamping structure 33 is arranged on the rotating component 3. Specifically, the rotating shaft mounting assembly 6 includes a bearing mounting seat 61 and a bearing 62 that cooperates with the rotating shaft 21 of the motor 2. Preferably, the bearing 62 in the embodiment of the present invention is a deep groove ball bearing. The deep groove ball bearing is suitable for the rotation speed of the rotating mechanism of the impact device of this embodiment when it is working, and is very durable and does not require frequent maintenance. The bearing 62 is arranged in the bearing mounting seat 61, and the bearing mounting seats 61 of the two rotating shaft mounting assemblies 6 are respectively fixed on the crossbeams 233 of the first support frame 12 and the second support frame 13.

[0031] Preferably, the rotating component 3 in the embodiment of the present invention includes a rotating frame 31 and a rotating auxiliary arm 32 provided on the rotating frame 31. The rotating frame 31 is fixed on the rotating shaft 21 of the motor 2 and is located between the first support frame 12 and the second support frame 13. At this time, the clamping structure 33 is provided on the rotating auxiliary arm 32. Before the collision test begins, the electronic detonator 0 is assembled: the prepared electronic control module of the electronic detonator 0 is installed into the steel sleeve of the electronic detonator 0. When the electronic detonator 0 is clamped on the rotating auxiliary arm 32, ensure that the length from the end of the rotating auxiliary arm 32 to the foot line of the steel sleeve of the electronic detonator 0 is controlled at the optimal impact position. Too long or too short will affect the impact effect, resulting in inaccurate experimental data.

[0032] In a preferred embodiment of the present invention, the rotating frame 31 includes four supporting and fixing rods 31, four connecting rods 32, and a fixed clamping wheel 9. The four supporting and fixing rods 31 and the fixed clamping wheel 9 are each provided with a connection hole that matches the outer diameter of the rotating shaft 21 of the motor 2. After the fixed clamping wheel 9 fixes the four supporting and fixing rods 31 together, it is fixed to the rotating shaft 21 of the motor 2 together with the four supporting and fixing rods 31 through their respective connection holes. The four connecting rods 32 respectively connect the four supporting and fixing rods 31 in pairs to form a quadrilateral structure of the rotating frame 31, thereby ensuring that the overall structure of the rotating frame 31 is stable and reliable. Among them, any two connecting rods 32 and one supporting and fixing rod 31 are connected and fixed together by studs 313 and two nuts 315, and a balancing wheel 314 is also provided at the connection between the connecting rods 32 and the supporting and fixing rods 31. The rotating auxiliary arm 32 is fixed to the studs 313 at the connection between any two connecting rods 32 and one supporting and fixing rod 31. In a preferred embodiment of the present invention, the rotating auxiliary arm 32 includes: a first auxiliary arm plate 321, a second auxiliary arm plate 322 and four connecting columns 323. The four connecting columns 323 relatively fix the first auxiliary arm plate 321 and the second auxiliary arm plate 322. The lower end of the first auxiliary arm plate 321 is fixed to the stud 313 at the connection between any two connecting rods 32 and a supporting fixing rod 31 of the rotating frame 31, and is fixed by a balance wheel 314 and a nut 315 at this location of the rotating frame 31. When the clamping structure 33 clamps the electronic detonator 0, the nut 315 at this location is also used to clamp the extended section of the foot wire of the electronic detonator 0, thereby preventing the electronic detonator 0 from falling off when it performs circular motion and collides, causing continuous impact and damaging the test sample.

[0033] Preferably, the clamping structure 33 provided in this embodiment of the present invention is disposed on the second auxiliary arm plate 322 of the rotating auxiliary arm 32. The clamping structure 33 includes an abutment plate 331, two push-pull rods 332, two compression springs 333, a connecting plate 334, a first clamping plate 335, and a second clamping plate 336. One end of each of the two push-pull rods 332 is fixed to the abutment plate 331, and the two compression springs 333 are respectively sleeved onto the two push-pull rods 332. A connecting frame 3221 is provided on the second auxiliary arm plate 322. Two connecting through-holes A are provided on each of the connecting plate 334 and the first clamping plate 335. Fixing holes B are provided on the second clamping plate 336 at positions corresponding to the respective connecting through-holes A on the first clamping plate 335. The connecting plate 334 and the first clamping plate 335 are fixed to the inner and outer sides of the second auxiliary arm plate 322, respectively. The two connecting through-holes A on the connecting plate 334 and the first clamping plate 335 are arranged opposite each other and located within the connecting frame 3221 of the second auxiliary arm plate 322. The other ends of the two push-pull rods 332, each sleeved with a compression spring 333, are respectively moved through the connecting through-holes A of the connecting plate 334 and the first clamping plate 335, and then fixedly connected to the fixing holes B on the second clamping plate 336. The first clamping plate 335 and the second clamping plate 336 are provided with clamping grooves 561 opposite each other. The clamping grooves 561 are used to clamp the leg wire of the electronic detonator 0. In other words, when the clamping grooves 561 of the first clamping plate 335 and the second clamping plate 336 are clamped together (at this time, the compression spring 333 is in a static state), A circular through-hole structure is formed that matches the outer diameter of the leg of the electronic detonator 0, thereby tightly clamping the leg of the electronic detonator 0 (at this time, the nut 315 at the fixed connection between the first auxiliary arm plate 321 and the stud 313 clamps the portion of the leg that extends out of the leg, further ensuring that the electronic detonator 0 will not fall off). To remove the electronic detonator 0, simply press the abutment plate 331 in the compression direction of the compression spring 333 until the push-pull rod 332 pushes the second clamping plate 336 to separate from the first clamping plate 335, and the electronic detonator 0 can be removed. It can be seen that the clamping structure 33 provided in this embodiment of the present invention is simple and easy to operate when clamping the electronic detonator 0, making it convenient to take it in and out.

[0034] During the test, since it is necessary to electrically connect the foot wire of the electronic detonator 0 to the detonator, and use an oscilloscope to follow up the rotation and impact process of the electronic detonator 0, at this time, if the electronic detonator 0 clamped on the rotating component 3 is directly electrically connected to the detonator, the wiring harness connecting the electronic detonator 0 and the detonator will be entangled or even broken during the rotation of the rotating component 3, affecting the test effect and causing great trouble to the operation process of the equipment. Therefore, the impact device provided by the embodiment of the present invention also includes an electrical contact sliding connector 4 located between the first support frame 12 and the rotating frame 31, the electrical contact sliding connector 4 includes a brush ring assembly 41 and a brush terminal holder 42 located below the brush ring assembly 41, the brush ring assembly 41 is slidably connected to the brush terminal holder 42 and is sleeved on the rotating shaft 21 of the motor 2, the brush terminal holder 42 is fixed on the first support frame 12, and the brush ring assembly 41 is provided with Multiple wiring terminals. After the electronic detonator 0 is clamped on the rotating auxiliary arm 32 by the clamping structure 33, the foot wire of the electronic detonator 0 is electrically connected to the wiring terminal provided on the brush ring assembly 41. At the same time, the brush terminal block 42 is externally connected to the peripheral interface workbench for connecting the detonator, and the detonator is electrically connected to the peripheral interface workbench. In this way, the electrical connection between the electronic detonator 0 and the detonator is realized. When the rotating shaft 21 of the motor 2 rotates and drives the rotating component 3 to rotate, the electronic detonator 0 performs a circular motion. At this time, the brush ring 41 connected to the foot wire of the electronic detonator 0 also rotates with the rotating shaft 21, thereby ensuring that the foot wire of the electronic detonator 0 will not be entangled during the rotation process, and it can also ensure that the detonator can be reliably and effectively electrically connected to the electronic detonator 0. At the same time, an oscilloscope is used to follow up the rotation and impact process of the electronic detonator 0, thereby recording the communication, capacitance, ignition and other related conditions of the electronic detonator 0 during the rotation and impact process.

[0035] The impact device provided in this embodiment of the present invention also includes a speed feedback device 7, which includes a speed sensing unit 71 and a speed feedback component. The speed sensing unit 71 is disposed outside the crossbeam 233 of the second support frame 13 and below the rotating shaft 21 of the motor 2. The speed feedback component includes an end cap 721 and a feedback plate 722 disposed on the end cap 721. The end cap 721 is disposed at the end of the rotating shaft 21 of the motor 2. The feedback plate 722 rotates with the rotating shaft 21 of the motor 2. The speed sensing unit 71 is provided with a beam sensor. The sensor detects and determines the speed of the rotating shaft 21 of the motor 2 and the position reached by the electronic detonator 0 through the feedback plate 722 that rotates with the rotating shaft 21. The sensor then feeds the relevant information back to the main control platform, which controls the operation of the motor 2 and the collision blocking mechanism 5 of the impact device. The collision blocking mechanism 5 includes a cylinder 51, a collision baffle 52, and a cylinder mounting seat 53. The cylinder mounting base 53 fixes the cylinder 51 on the base 11 of the support frame 1, and the extension direction of the piston rod of the cylinder 51 is toward the rotating frame 31, and the bottom end of the piston rod of the cylinder 51 is fixedly connected to the collision baffle 52. During the specific test, the output pipe of the air compressor is connected to the input end of the air pressure control valve of the cylinder 51 of the impact device, the air compressor switch button is started, the air pressure of the air compressor is set to a preset value (such as 2 bar), and the motor 2 is started. The tester sets the speed of the motor 2, the extension length of the piston rod of the cylinder 51 (that is, the length of the collision baffle 52 extending toward the rotating frame 31) and other parameters on the main control platform. For example, the speed of the motor 2 can be set to 130r / min and the action time of the cylinder 51 can be set to 0.8s (the parameters can be set according to the actual test requirements, collision force, etc.). When the impact device is working, the rotating shaft 21 of the motor 2 drives the rotating parts. 3, the electronic detonator 0 with the foot line rotates. After the speed of the motor 2 stabilizes, the rotating wheel of the motor 2 stops running, and then the electronic detonator 0 continues to rotate by inertia. When the sensor of the speed sensing unit 71 detects that the electronic detonator 0 has passed the preset position, the main control platform controls the cylinder 51 to move and push the collision baffle 52 toward the rotating frame 31, blocking the travel path of the electronic detonator 0. The electronic detonator 0 can then collide with the collision baffle 52 at high speed. At the same time, an oscilloscope is used to track the rotation and collision process, and record the communication, capacitance, and ignition related conditions of the electronic detonator 0. The main control platform in the embodiment of the present invention is an existing control device and will not be described in detail here.

[0036] The impact equipment provided by the present invention is used for the impact test of the electronic detonator 0. During the test, the electronic detonator 0 with the foot line only needs to be clamped on the clamping structure 33 provided on the rotating mechanism. The rotating mechanism rotates and drives the electronic detonator 0 clamped by the clamping structure 33 to collide with the collision blocking mechanism. Before the rotation and impact of the electronic detonator 0, the foot line of the electronic detonator 0 is electrically connected to the detonator through the electrical contact sliding connector 4. At the same time, an oscilloscope is used to follow up the rotation and impact process of the electronic detonator 0, and record the communication, capacitance, ignition and other related conditions of the electronic detonator 0 during the rotation and impact process. Moreover, since the speed of the power source motor rotating the rotating mechanism is controllable, the collision force during the collision test is controllable, and the test process saves time and effort, thereby conveniently measuring whether the anti-impact performance of the capacitor provided by the supplier is good, and avoiding a series of explosion refusal problems caused by the poor anti-impact performance of the capacitor, fast power loss, no power storage after secondary charging, and the like.
