Description

Technical Field

[0001] This invention relates to the field of door panel impact testing technology, and in particular to an impact detection device for explosion-proof valves. Background Technology

[0002] After the production of blast wave ventilators is completed, the finished samples generally need to be tested. Among them, impact testing is one of the most important test items. The core purpose of impact testing on blast wave ventilators is to verify their key protective performance by simulating high-speed projectiles or severe overpressure loads generated by blast wave shock waves. This includes the impact deformation resistance of the ventilator structure, the reliability of dynamic sealing, and the functionality of key components such as hinges and locking devices. This ensures that the ventilator can effectively block shock waves and debris in a real explosion accident, thus protecting the safety of personnel and equipment inside.

[0003] However, existing explosion-proof door impact tests typically use a single hammer to strike the door, resulting in a monotonous impact area and shape. Furthermore, the material properties of the impact shaft cannot be altered, failing to accurately simulate real-world conditions. Additionally, existing explosion-proof door impact testing devices cannot change the absorption method of the reverse impact force, nor can they effectively utilize the reaction impact generated during the impact process. After impact, the vibrations generated are transmitted to the ground or vibration damping devices, preventing the secondary utilization of the vibration kinetic energy. Therefore, an explosion-proof door impact testing device is needed that can switch between impact heads of different sizes and shapes, and impact shafts made of different materials, while also effectively utilizing the reverse impact force and vibrations generated during the impact, to address the shortcomings of existing explosion-proof door impact testing devices. Summary of the Invention

[0009] Furthermore, the hammering device includes a hammer changing assembly, a hammering sleeve, a liquid storage sleeve, a liquid passage hole, a hammering support, a rigid component, a vent hole, and a hammering base; the hammer changing assembly is slidably installed in the hammering sleeve along the axial direction; the hammering sleeve is fixedly installed at the front end of the liquid storage sleeve; the liquid storage sleeve is fixedly installed at the front end of the hammering support; the liquid passage hole is fixedly installed on the side of the liquid storage sleeve; the rigid component is fixedly installed at the rear end of the hammering support; the vent hole is fixedly installed on the side of the liquid storage sleeve; and the upper end of the hammering base is fixedly installed at the lower end of the hammering support.

[0010] Furthermore, the hammer changing assembly includes an impact shaft, a limiting cover, a hammer changing drum, a hammer changing sleeve, a locking sleeve, a locking shaft, a hammer changing base, a hammer changing bracket, a hammer changing slide bar, and a hammer changing hole; the impact shaft is placed inside the hammer changing bracket; the hammer changing bracket is fixedly installed inside the hammer changing sleeve; the limiting cover is fixedly installed at the front end of the hammer changing sleeve; the hammer changing drum is rotatably connected to the periphery of the hammer changing sleeve; a through hole is provided on the side of the hammer changing drum; the hammer changing sleeve is fixedly installed at the front end of the hammer changing base; the hammer changing sleeve is also slidably installed inside the hammer changing sleeve; a through hole is provided on the side of the hammer changing sleeve; the locking sleeve is fixedly installed at the front end of the hammer changing base; the locking shaft is slidably installed inside the locking sleeve along the axial direction; the hammer changing base is slidably installed inside the liquid storage sleeve; the hammer changing slide bar is fixedly installed inside the locking shaft by a spring; and the hammer changing hole is fixedly installed at the rear end of the hammer changing base.

[0011] Furthermore, the impact shaft includes an impact hammer head, an impact sleeve, a first shaft body, and a second shaft body. The impact hammer head is fixedly installed inside the impact sleeve by fastening bolts. The impact sleeve is fixedly installed at the front end of the first shaft body. The outer cylindrical surface of the second shaft body contacts the inner side of the hammer changing bracket. The diameter of the second shaft body is larger than that of the first shaft body. When the impact shaft is pushed out from the hammer changing bracket, the first shaft body and the second shaft body will align with the axis of the hammer changing sleeve. Then, the spring on the hammer changing slide rod will drive the hammer changing slide rod and the second shaft body to slide forward, so that the first shaft body extends out from the limiting cover. When the first shaft body is fully extended, the front end of the second shaft body will be stuck by the inner wall of the limiting cover, thereby replacing different types of impact shafts.

[0012] Furthermore, the rigid component includes a rigid slider, a rigid base, and a rigid pipe; the rigid slider is slidably installed inside the rigid base along the axial direction; the rigid base is fixedly installed at the rear end of the hammer support; the rear end of the rigid base is also provided with a liquid filling hole; the rigid pipe is fixedly installed on the side of the rigid base along the radial direction; the rigid pipe is also connected to a one-way pressure valve on the side of the control slide.

[0013] Furthermore, the support device includes a support base, a support frame, a hammer slide, a support mounting base, and a support socket; the support base is fixedly installed on the ground by bolts; the support frame is fixedly installed on the upper end of the support base by bolts; the hammer slide is slidably installed on the inner side of the support base; the upper end of the hammer slide is fixedly connected to the lower end of the hammer base; the support mounting base is fixedly installed on the front end of the support base; and the support socket is fixedly installed on the upper end of the support mounting base.

[0014] Furthermore, the reinforcement device includes a reinforcement frame and a reinforcement rod; the reinforcement frame is fixedly installed on the upper end of the support mounting base by bolts; the reinforcement rod is slidably installed inside the reinforcement frame in the vertical direction; the reinforcement rod is also inserted into the support socket.

[0015] The beneficial effects of this invention compared with the prior art are: (1) When the control spring drives the liquid storage slider and the gas storage slider to slide forward by its own elastic force, the liquid storage slider and the gas storage slider will also drive the hammering device to slide forward together. When the hammering device hits the explosion-proof valve, the vibration will be transmitted to the control housing through the reinforcement device and the support device, and then transmitted from the control housing to the crank plate. At this time, the center of gravity of the crank plate is biased to the upper front. The vibration will cause the center of gravity of the crank plate to rotate forward. At the same time, the crank plate drives the oiling roller to rotate and drives the lubricating oil in the oiling assembly to enter the upper surface of the oiling slope, and then flows from the upper surface of the oiling slope into the interior of the control housing to realize the automatic lubrication function and the recycling of vibration. (2) The staff member holds the long rod and pushes the hammer changing slide back into the locking shaft. Then, the hammer changing drum is manually rotated so that the through hole on the hammer changing drum is aligned with the through hole on the hammer changing sleeve. Then, the impact shaft is pushed out of the hammer changing bracket by the long rod so that the first shaft and the second shaft are aligned with the axis of the hammer changing sleeve. Then, the two long rods are manually pulled out. At this time, the spring on the hammer changing slide causes the hammer changing slide and the second shaft to slide forward, so that the first shaft extends out from the limiting cover. When the first shaft is fully extended, the front end of the second shaft will be stuck by the inner wall of the limiting cover, thereby replacing the impact shaft of different material types. (3) Liquid or gas enters the liquid storage sleeve through the liquid passage or vent, and then the liquid or gas enters the clamping sleeve through the hammer changing hole on the hammer changing base. The gas or liquid will push the clamping shaft in the clamping sleeve to extend forward. At this time, the front end of the second shaft will be clamped by the inner wall of the limiting cover, so that the spring between the clamping shaft and the hammer changing slide is gradually compressed until the spring is fully compressed. At this time, the hammer changing slide and the limiting cover will clamp the second shaft to achieve further reinforcement of the impact shaft. (4) When liquid or gas is being filled into the reservoir sleeve, hydraulic oil is added from the filling hole at the rear end of the rigid base, and then the filling hole is closed. When the impact shaft collides with the explosion-proof wave valve, the reverse impact force will act on the impact shaft in the opposite direction, and then be transmitted to the hammer changing sleeve through the impact shaft. The hammer changing sleeve will transmit the reverse impact force to the rigid slider through the liquid in the reservoir sleeve. At this time, the rigid slider will retract back into the rigid base, so that the hydraulic oil in the rigid base is discharged into the control slide through the one-way pressure valve on the side of the control slide. Then, the deviation between the actual impact force and the theoretical impact force is judged according to the volume of hydraulic oil in the control slide. Attached Figure Description

[0043] Working principle of the invention: Figure 1 The invention provides its usage and corresponding scenarios. The attitude control during the blast wave door impact test is determined by the hammer impact device 2, the control device 4, and the reinforcement device 5. The attitude of the hammer impact device 2 and the attitude of the reinforcement device 5 are determined by the control device 4. Therefore, the control device 4 is the core of the blast wave door impact test process.

[0044] Taking a preferred embodiment as an example, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the worker holds a long rod and pushes the hammer-changing slide rod 217 back into the locking shaft 214. Then, the hammer-changing drum 211 is manually rotated so that the through hole on the hammer-changing drum 211 is aligned with the through hole on the hammer-changing sleeve 212. Then, the impact shaft 209 is pushed out from the hammer-changing bracket 216 of the hammer-changing assembly 201 using the long rod, so that the first shaft 221, the second shaft 222 and the axis of the hammer-changing sleeve 212 are aligned. Then, the two long rods are manually pulled out. At this time, the spring on the hammer-changing slide rod 217 drives the hammer-changing slide rod 217 and the second shaft 222 to slide forward, so that the first shaft 221 extends out from the limiting cover 210. When the first shaft 221 is fully extended, the front end of the second shaft 222 is locked by the inner wall of the limiting cover 210. This allows for the replacement of impact shafts 209 with different material types; subsequently, different styles of impact hammers 219 are manually inserted into the impact sleeve 220, and the impact hammers 219 and impact sleeve 220 are tightened with fastening bolts; the liquid pump in the liquid storage slider 409 or the air pump in the air storage slider 410 will drive liquid or gas to enter the liquid storage sleeve 203 through the liquid passage hole 204 or the air passage hole 207, and then the liquid or gas will enter the locking sleeve 213 through the hammer replacement hole 218 on the hammer replacement base 215 from the liquid storage sleeve 203. The gas or liquid will push the locking shaft 214 in the locking sleeve 213 to extend forward, and at this time the front end of the second shaft 222 will be locked by the inner wall of the limiting cover 210, so that the locking shaft 214 in the locking sleeve 213 extends forward. The spring between the positioning shaft 214 and the hammer-changing slide 217 is gradually compressed until it is fully compressed. At this time, the hammer-changing slide 217 and the limit cover 210 will clamp the second shaft 222 to further reinforce the impact shaft 209. When liquid or gas is being filled into the accumulator sleeve 203, hydraulic oil is manually added from the filling hole at the rear end of the rigid base 224. The hydraulic oil will cause the rigid slider 223 to extend forward in the rigid base 224, and then the filling hole of the rigid component 206 will be closed to achieve synchronous filling of the accumulator sleeve 203 and the rigid base 224. When the impact shaft 209 collides with the explosion-proof wave valve, the reverse impact force will act on the impact shaft 209 in the reverse direction, and then be transmitted to the impact shaft 209. On the hammer-changing sleeve 212, the reverse impact force is transmitted to the rigid slider 223 through the liquid in the accumulator sleeve 203. At this time, the rigid slider 223 retracts back into the rigid base 224, so that the hydraulic oil in the rigid base 224 is discharged into the control slide 411 through the rigid pipe 225 and the one-way pressure valve on the side of the control slide 411. Then, the deviation between the actual impact force and the theoretical impact force is judged according to the volume of hydraulic oil in the control slide 411. The hammer sleeve 202 is used for the sliding installation of the hammer-changing sleeve 212. When a large impact force impact test is performed, the filling material in the accumulator sleeve 203 is gas, and when a small impact force impact test is performed, the filling material in the accumulator sleeve 203 is liquid.

[0045] like Figure 2 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13As shown, motor 418 drives control roller 413 to rotate, control roller 413 drives pull belt 402 to wind up, pull belt 402 drives control slide 411 and control support block 412 to slide backward. Control slide 411 drives control spring 408 to stretch through liquid storage slider 409 and gas storage slider 410. At the same time, control slide 411 also drives hammer slide 103 to slide backward on support base 101 on support device 1. Hammer slide 103 drives hammer base 208 and hammer support 205 to slide backward. Hammer support 205 drives hammer changing assembly 201 to slide backward, thus realizing the power storage function. When the electric push rod on the output end of motor 418 retracts, the output end of motor 418 will interact with control roller 413. Upon disengagement, the control spring 408, relying on its own elasticity, drives the liquid storage slider 409 and the gas storage slider 410 to slide forward. At this time, the liquid storage slider 409 and the gas storage slider 410 also drive the hammering device 2 to slide forward together. When the hammering device 2 impacts the explosion-proof valve, the vibration is transmitted through the reinforcing frame 501 of the reinforcing device 5 to the support mounting base 104 and the support base 101, then from the support base 101 to the support frame 102, then from the support frame 102 to the control housing 401, and finally from the control housing 401 to the crank disc 416. At this time, the center of gravity of the crank disc 416 is biased to the upper front, and the vibration will cause the center of gravity of the crank disc 416 to rotate forward. 416 drives the oiling roller 406 to rotate, causing the lubricating oil in the oiling assembly 405 to enter the upper surface of the oiling ramp 407. The lubricating oil then flows from the upper surface of the oiling ramp 407 into the interior of the control housing 401, achieving automatic lubrication and vibration recovery. The absorbent cloth 420 of the oiling assembly 405 permeates the lubricating oil in the oiling tank 419 into the absorbent rod 421. The absorbent rod 421 then permeates the lubricating oil onto the surface of the roller body 423. When the oiling hole 422 approaches the absorbent rod 421, the lubricating oil on the absorbent rod 421 drips into the oiling hole 422. As the roller body 423 rotates, the oiling hole 422 transports the lubricating oil to the upper surface of the oiling ramp 407. The oil then flows from the oiling ramp 407 to the control roller 413 and control pulley 414 to achieve lubrication. By adjusting the tightness of the crankshaft disc 416 and the right side of the control housing 401, the rotation angle of the crankshaft disc 416 during each vibration can be controlled, thereby controlling the relationship between the number of vibrations and the amount of lubricating oil. This allows for automatic addition of lubricating oil when the operator forgets to lubricate regularly. After the lubricating oil is applied, the operator needs to manually restore the position of the crankshaft disc 416. The operator can also manually rotate the crankshaft disc 416 to achieve the oiling function. When facing a large impact test, the reinforcement rod 502 can be manually inserted into the reinforcement frame 501 and the support socket 105 to achieve temporary reinforcement.Necessary control components are placed between the main unit housing 403 and the control top cover 404. The interior of the main unit housing 403 is filled with sponge, foam, and air cushions to reduce impact damage to the control components. The liquid reservoir 415 supplies liquid to the liquid storage slider 409; the gas reservoir 417 supplies gas to the gas storage slider 410; and the protective plate 3 is fixedly installed on the left side of the control housing 401.

[0046] This invention is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort are within the protection scope of this invention.
