Description

Technical Field

[0001] This invention relates to the field of road safety facility testing technology, and more specifically, to a pressure resistance testing device for crash barriers. Background Technology

[0002] As a road safety protection facility, the compressive strength of crash barriers is a key indicator to ensure their protective function. To ensure that crash barriers can effectively withstand loads such as vehicle collisions, stacking compression, and lateral crushing in actual use, relevant standards (such as GB / T 28650 "Highway Crash Barriers") put forward clear test requirements for the compressive strength of crash barriers. It is necessary to apply a specified load to the barrel body through special testing equipment to verify its structural strength and resistance to deformation.

[0003] However, during the pressure resistance test of the impact-resistant barrel, when the pressure is applied to the barrel's limit, the barrel is prone to bursting, producing high-speed flying plastic fragments. At the same time, some components of the barrel are ejected due to the instantaneous release of pressure, posing a serious threat to the personal safety of operators and the surrounding environment. Especially under low-temperature testing conditions (such as the standard requirement of -40℃), the barrel material becomes brittle, and the bursting is more violent, further aggravating the hazards of flying and ejected fragments. On the other hand, the instantaneous impact force generated by the bursting of the barrel is directly transmitted to the inside of the cylinder or hydraulic cylinder through the pressure plate and piston rod, which can easily cause fatigue damage or structural damage to its precision components (such as seals, pistons, and cylinder end caps), affecting the service life of the equipment and the testing accuracy. Summary of the Invention

[0004] To address the problems existing in the prior art, the purpose of this invention is to provide a pressure resistance testing device for anti-collision barrels, which can realize the formation of a semi-circular plate to form a protective barrier to block and intercept explosive fragments, and the inclined block to limit and block the impact force on the pressure plate in stages, so as to ensure the safety of operators and avoid the impact force from being transmitted to the cylinder and causing structural damage.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A pressure resistance testing device for impact-resistant barrels includes a test bench and further includes: Two semi-circular plates are symmetrically slidably mounted on the top of the test platform; Two cylinders are provided, which are fixedly installed on the test platform and located on opposite sides of the two semicircular plates. The output ends of the two cylinders are fixedly connected to the adjacent semicircular plates, and are used to drive the two semicircular plates to move closer to each other to close into a cylinder or move away from each other to open. The top mount is fixedly installed above the test bench; Cylinder 2 is fixedly installed at the bottom of the top seat; The pressing assembly includes a pressure plate one and a pressure plate two. The pressure plate one is fixedly installed at the output end of the cylinder two. The pressure plate two is located below the pressure plate one and is the same size as the pressure plate one. Several heavy-duty springs are evenly fixedly installed between the pressure plate one and the pressure plate two. The elastic force of the heavy-duty springs is greater than the maximum pressure that the anti-collision barrel can withstand. The diameters of the pressure plate one and the pressure plate two are adapted to the inner diameter of the cylinder formed by the two semi-circular plates when they are closed. A limiting component is disposed on the opposite sides of the two semicircular plates to form a step-by-step limiting and blocking effect on the second pressure plate when it is impacted and moves upward.

[0007] Furthermore, the limiting component includes slots evenly opened on opposite sides of the two semicircular plates, and an inclined block is slidably installed in the inner cavity of each set of slots. An elastic spring is fixedly installed between each set of inclined blocks and the inner cavity of the adjacent slot. The contact surfaces of the pressure plate one and the pressure plate two with the inclined block are both set to arc shape. The pressure plate one, the pressure plate two and the inclined block have the same height. The distance between the pressure plate one and the pressure plate two is equal to the sum of the heights of the two inclined blocks.

[0008] Furthermore, magnet blocks are uniformly fixedly installed at the bottom of the top seat, and vertical rods are magnetically attached to the bottom of each group of magnet blocks. The first pressure plate and the second pressure plate are slidably installed with each group of vertical rods. A fixing plate is fixedly installed on the rod wall of each group of vertical rods. Each group of fixing plates is located below the second pressure plate. A sleeve frame is fixedly installed on the outer wall of each group of vertical rods. The inner diameter of the sleeve frame is adapted to the diameter of the two groups of semicircular plates combined. Each set of vertical rods has a guide rod slidably installed inside its top end. Each set of guide rods is fixedly installed to the bottom of the adjacent magnet block. Each set of guide rods has an elastic rope inside its cavity. The two ends of each set of elastic ropes are fixedly installed to the inner wall of the adjacent magnet block and the inner cavity of the vertical rod, respectively.

[0009] Furthermore, a plurality of openings are evenly provided on the test platform and below the pressure plate two, and a funnel is fixedly installed at the bottom of the test platform, with the bottom of each opening located within the opening range of the top of the funnel.

[0010] Furthermore, each set of heavy-duty springs is provided with a cylindrical block fixedly installed with the second pressure plate. A special-shaped lead screw is threaded into the top of each set of cylindrical blocks. The first pressure plate is provided with a movable groove that matches the special-shaped lead screw of each set. A gear is sleeved on the upper part of each set of special-shaped lead screws. Each set of gears is rotatably installed on the top of the first pressure plate. A limit block is fixedly installed at the top of each set of special-shaped lead screws. Each set of limit blocks abuts against the top of the adjacent gear. A gear ring is meshed between each set of gears. The gear ring is located outside the output end of the second cylinder and is rotatably installed on the top of the first pressure plate.

[0011] Furthermore, a movable plate is rotatably mounted on the top of one of the limiting blocks, and a marking plate is slidably mounted on the rear side of the movable plate. The marking plate is fixedly mounted to the pressure plate, and a paintbrush is detachably mounted on the movable plate. The output end of the paintbrush is in contact with the marking plate.

[0012] Furthermore, a pull rope is fixedly installed on one side of the top of the frame, and guide rollers for conveying the pull rope are evenly installed on the bottom of the top seat.

[0013] Furthermore, the upper part of each set of irregularly shaped lead screws is non-circular to ensure that the irregularly shaped lead screw can slide on the gear and rotate with it.

[0014] Furthermore, a protective pad is installed on the bottom wall of the inner cavity of the sleeve frame.

[0015] Furthermore, the bottom diameter of the vertical rod is adapted to the diameter of the leak, and when the vertical rod falls to the top of the test platform, its bottom end inserts into the corresponding leak.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The present invention forms a cylinder by joining two semicircular plates together, which surrounds the outside of the anti-collision barrel. When the barrel bursts, the fragments are intercepted inside and cannot be scattered. At the same time, the inclined blocks driven by elastic springs on the inner side of the semicircular plates form a step-by-step limiting structure. When the pressure plate moves up, it abuts against the bottom of the inclined block to block the upward transmission of the impact force, thus avoiding damage to the cylinder and realizing the integrated protection of fragments and impact isolation.

[0017] (2) When the pressure plate moves down, it pushes the fixing plate, so that the vertical rod is freed from the magnetic attraction of the magnet and falls to the top of the test platform by gravity. Multiple vertical rods form a lateral limit around the outside of the barrel to prevent the barrel from tipping over when it is under pressure. At the same time, the vertical rod drives the sleeve frame to be locked on the top of the two semicircular plates radially to prevent the bursting impact from breaking the semicircular plates and to ensure that the semicircular plates remain closed at the moment of bursting.

[0018] (3) The present invention uses the evenly distributed openings on the test bench and the funnel installed at the bottom. When the water or sand filling barrel bursts, the leaked water or sand flows into the funnel through the openings and is collected and discharged, which avoids the accumulation of the medium on the surface of the test bench and affects the subsequent test environment or causes equipment pollution. At the same time, it is easy to clean.

[0019] (4) The present invention drives the gear and the special-shaped screw to rotate through the gear ring, so that the cylindrical block pulls the pressure plate two to move relative to the pressure plate one to adjust the preload of the heavy-duty spring and adapt to the testing requirements of different specifications of barrels; at the same time, when the pressure plate two moves up, the cylindrical block pushes the special-shaped screw to drive the movable plate and the pen to leave marks on the marking plate, intuitively recording the relative magnitude of the bursting impact force, and providing a traceable basis for the quality assessment of the barrel.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1 to 7 A pressure resistance testing device for anti-collision barrels includes a test bench 1, and further includes: Two semicircular plates 101 are symmetrically slidably mounted on the top of the test bench 1; There are two cylinders 102, which are fixedly installed on the test bench 1 and located on opposite sides of the two semicircular plates 101. The output ends of the two cylinders 102 are fixedly connected to the adjacent semicircular plates 101, and are used to drive the two semicircular plates 101 to move closer to each other to close into a cylinder or to move away from each other to open. Top mount 103 is fixedly installed above test bench 1; Cylinder 2 104 is fixedly installed at the bottom of top seat 103; The pressing assembly includes a first pressing plate 105 and a second pressing plate 106. The first pressing plate 105 is fixedly installed at the output end of the second cylinder 104. The second pressing plate 106 is located below the first pressing plate 105 and is the same size as the first pressing plate 105. Several heavy-duty springs 107 are evenly fixedly installed between the first pressing plate 105 and the second pressing plate 106. The elastic force of the heavy-duty springs 107 is greater than the maximum pressure that the anti-collision barrel can withstand. The diameters of the first pressing plate 105 and the second pressing plate 106 are adapted to the inner diameter of the cylinder formed after the two semi-circular plates 101 are closed. The limiting components are located on opposite sides of the two semicircular plates 101 and are used to limit and block the pressure plate 106 step by step when it is impacted and moves upward.

[0024] The limiting component includes slots 110 evenly opened on opposite sides of two semi-circular plates 101. Each set of slots 110 has an inclined block 112 slidably installed in its inner cavity. Each set of inclined blocks 112 is fixedly installed with an elastic spring 111 between it and the inner cavity of the adjacent slot 110. The contact surfaces of pressure plate 105 and pressure plate 2 106 with the inclined block 112 are all set to be arc-shaped. The heights of pressure plate 105, pressure plate 2 106 and inclined block 112 are the same, and the distance between pressure plate 105 and pressure plate 2 106 is equal to the sum of the heights of the two inclined blocks 112.

[0025] By adopting the above technical solution, the anti-collision barrel to be tested is first placed on top of the test platform 1 between the two semicircular plates 101. This can be an empty barrel, a barrel filled with water, or a barrel filled with sand. At this time, the anti-collision barrel is directly below the pressure plate 106. The cylinder 102 is then activated, and the output ends of the two cylinders 102 extend to push the semicircular plates 101 on them to slide on the top of the test platform 1. At this time, the two semicircular plates 101 approach and contact each other on the top of the test platform 1. 1. The components are combined to form a cylinder surrounding the outer side of the crash barrier. Activating cylinder 2 104 causes its output end to extend and push pressure plate 1 105 downwards. Pressure plate 1 105, via heavy-duty spring 107, drives pressure plate 2 106 downwards synchronously. When pressure plate 2 106 enters the two semi-circular plates 101, a small gap is formed between pressure plate 2 106 and the inner walls of the two semi-circular plates 101. When the bottom of pressure plate 2 106 contacts the uppermost inclined block 112... As the inclined plane continues to move downwards, pressure plate 2 106 will squeeze the inclined block 112 to slide outwards within the inner cavity of slot 110 and compress the elastic spring 111. When the side wall of pressure plate 2 106 disengages from the uppermost inclined block 112 and moves to its lower side, under the force of the elastic spring 111, the elastic spring 111 returns to its initial state and pushes the inclined block 112 to its initial position, located above pressure plate 2 106. Pressure plate 1 105 and pressure plate 2 106 are in two half- The same process applies to the downward movement of the circular plates 101. The elastic force of the heavy-duty spring 107 is greater than the maximum pressure that the anti-collision barrel can withstand, so as to ensure that the downward pressing of the pressure plate 106 is a rigid pressure. When the pressure plate 106 contacts the top of the anti-collision barrel and continues to move downward, the pressure plate 106 can perform the downward pressure test on the anti-collision barrel. Parts of the two semi-circular plates 101 are set with visual materials so that the state of the anti-collision barrel during the pressure resistance test can be seen. When the crash barrier bursts during the compression process, the magnitude of the force is: bursting impact force > cylinder 104 thrust > heavy-duty spring 107 elastic force > pressure borne by the crash barrier. The impact force generated by the bursting crash barrier will act on the bottom of pressure plate 106. At this time, the impact force will instantly push pressure plate 106 upward. The upward movement of pressure plate 106 will compress the heavy-duty spring 107. The compression deformation of the heavy-duty spring 107 absorbs the impact energy, smoothing out the sharp instantaneous impact peak and avoiding direct hard transmission of the impact force. By ensuring that the heights of pressure plate 105, pressure plate 106, and inclined block 112 are the same, and the distance between pressure plate 105 and pressure plate 106 is equal to the sum of the heights of the two inclined blocks 112, it is ensured that pressure plate 105 and pressure plate 106 are at any height within the two semicircular plates 101. Each cylinder has at least one inclined block 112 located between pressure plate 2 106 and pressure plate 105 as a limiting base, realizing real-time and segmented limiting of the upward stroke of pressure plate 2 106, thereby blocking the path of the bursting impact force to continue to be transmitted upward, so that the impact force of the anti-collision barrel bursting will not act on pressure plate 105, and also protecting cylinder 2 104, effectively preventing the impact force from being transmitted along the piston rod to the inside of the cylinder, causing fatigue damage or structural damage to precision components such as sealing rings, pistons, and cylinder end caps, extending the service life of the equipment, and ensuring long-term testing accuracy; at the same time, the plastic fragments generated by the bursting will also be blocked by the semi-circular plate 101, which forms a protective barrier to effectively prevent fragments from flying at high speed towards the operator, eliminating personnel safety hazards. It is also applicable when the barrel body becomes brittle and fractures under low temperature testing conditions. After the impact force generated by the explosion ends, under the action of the heavy-duty spring 107, the heavy-duty spring 107 returns to its initial state and pushes the pressure plate 106 down to its initial position.

[0026] like Figure 2 , Figure 3 and Figure 6 As shown, magnet blocks 201 are evenly fixedly installed at the bottom of the top seat 103. Each set of magnet blocks 201 has a vertical rod 2 magnetically attached to its bottom. Pressure plate 105 and pressure plate 206 are slidably installed with each set of vertical rods 2. Fixing plate 204 is fixedly installed on the rod wall of each set of vertical rods 2. Each set of fixing plates 204 is located below pressure plate 206. A sleeve frame 205 is fixedly installed on the outer wall of each set of vertical rods 2. The inner diameter of the sleeve frame 205 is adapted to the diameter of the two sets of semicircular plates 101 after combination. Each set of vertical rods 2 has a guide rod 202 slidably installed inside the top end. Each set of guide rods 202 is fixedly installed to the bottom of the adjacent magnet block 201. Each set of guide rods 202 has an elastic rope 203 in its inner cavity. The two ends of each set of elastic ropes 203 are fixedly installed to the inner cavity wall of the adjacent magnet block 201 and the vertical rod 2, respectively.

[0027] By adopting the above technical solution, when the output end of cylinder 2 104 pushes the pressure plate 2 106 downward, when the bottom of the pressure plate 2 106 contacts the fixed plate 204 and continues to move downward, the pressure plate 2 106 will push the vertical rod 2 downward through the fixed plate 204. The top of the vertical rod 2 will break away from the magnetic attraction of the magnet block 201 and fall by its own gravity. By setting the elasticity of the elastic rope 203, the speed of the vertical rod 2's descent can be slowed down to prevent it from falling instantly. The vertical rod 2 will slowly slide down along the wall of the guide rod 202. After each set of vertical rods 2 falls to the top of the test platform 1, they will surround the outside of the anti-collision barrel to limit the anti-collision barrel and prevent it from tilting to the side due to uneven force or barrel deformation during the pressing process. This ensures that the pressure always acts vertically on the top of the barrel, improving test stability and data accuracy. As the vertical rod 2 moves downward, it will drive the sleeve 205 to move synchronously. When the vertical rod 2 falls to the top of the test platform 1, the vertical rod 2 will drive the sleeve 205 to lock onto the top of the two semicircular plates 101. At this time, the two semicircular plates 101 can be limited to prevent the impact force generated by the explosion of the anti-collision barrel from causing the two semicircular plates 101 to move outward. This ensures that the semicircular plates 101 remain in an enclosed state at the moment of explosion, avoiding the expansion of the fragmentation range or the failure of protection due to the impact force breaking through the protective barrier. This improves the stability of the protection process and further protects the cylinder 102.

[0028] like Figure 2 As shown, a number of openings 3 are evenly provided on the test platform 1 and below the pressure plate 2 106. A funnel 301 is fixedly installed at the bottom of the test platform 1, and the bottom of each opening 3 is located within the opening range of the top of the funnel 301.

[0029] By adopting the above technical solution, and through the setting of the leak 3, when the water or sand anti-collision barrel bursts during the pressure resistance test, the water or sand will flow into the funnel 301 through the leak 3. A collection frame can be added below the funnel 301 to collect it, realizing the automatic discharge and centralized collection of water or sand, avoiding the accumulation of residual media on the test platform 1, which would affect the subsequent test environment or cause equipment pollution, and at the same time, it is easy to clean.

[0030] like Figure 3 and Figure 5As shown, each set of heavy-duty springs 107 is provided with a cylindrical block 4 fixedly installed with pressure plate 2 106. A special-shaped lead screw 401 is threadedly installed at the top of each set of cylindrical blocks 4. The pressure plate 105 is provided with a movable groove 404 that matches each set of special-shaped lead screws 401. A gear 402 is sleeved on the upper part of each set of special-shaped lead screws 401. Each set of gears 402 is rotatably installed on the top of pressure plate 105. A limit block 408 is fixedly installed at the top of each set of special-shaped lead screws 401. Each set of limit blocks 408 abuts against the top of the adjacent gear 402. A gear ring 403 is meshed between each set of gears 402. The gear ring 403 is located outside the output end of cylinder 2 104 and is rotatably installed on the top of pressure plate 105.

[0031] A movable plate 406 is rotatably mounted on the top of one set of limit blocks 408. A marking plate 405 is slidably mounted on the rear side of the movable plate 406. The marking plate 405 is fixedly mounted with the pressure plate 105. A paintbrush 407 is detachably mounted on the movable plate 406. The output end of the paintbrush 407 is in contact with the marking plate 405.

[0032] By adopting the above technical solution, the gear ring 403 is rotated by the tool to drive the gears 402 to rotate. When the gears 402 rotate, they will drive the special-shaped lead screw 401 on them to rotate synchronously. When the special-shaped lead screw 401 is tightened and rotated on the cylindrical block 4, the limit block 408 contacts the top of the gear 402 to play a limiting role. This allows the cylindrical block 4 to pull the pressure plate 106 upward and squeeze the heavy-duty spring 107. If the special-shaped lead screw 401 is loosened and reversed on the cylindrical block 4, the elastic force of the heavy-duty spring 107 will push the pressure plate 106 to drive the cylindrical block 4 to move downward accordingly. At this time, the distance between the pressure plate 106 and the pressure plate 105 can be adjusted to adjust the elastic preload of the heavy-duty spring 107, thereby adapting to the testing requirements of different counterweight states or different specifications of anti-collision barrels such as empty barrels, water-filled barrels, and sand-filled barrels. The adjustment of the special-shaped lead screw 401 can achieve precise matching between the elastic force and the test load, improving the versatility and flexibility of the equipment. When the impact force of the crash barrier bursting pushes the pressure plate 106 upward to compress the heavy-duty spring 107, the pressure plate 106 pushes the irregular lead screw 401 upward on the gear 402 through the cylindrical block 4. At the same time, the irregular lead screw 401 moves upward and drives the movable plate 406 to move upward synchronously on the front wall of the marking plate 405 through the limit block 408. At this time, the movable plate 406 with the drawing pen 407 can paint and leave marks on the path of the movement of the front wall of the marking plate 405, thereby forming a quantitative record mark of the bursting impact force. This allows the testers to intuitively judge the relative magnitude and trend of the impact force in each test, providing traceable data for the quality assessment of the barrel and the adjustment of test standards.

[0033] like Figure 2 , Figure 3and Figure 7 As shown, a pull rope 206 is fixedly installed on one side of the top of the frame 205, and guide rollers 207 for conveying the pull rope 206 are evenly installed on the bottom of the top seat 103.

[0034] The upper part of each set of irregular lead screws 401 is non-circular to ensure that the irregular lead screw 401 can slide on the gear 402 and rotate with it.

[0035] A protective pad 208 is installed on the bottom wall of the inner cavity of the sleeve 205.

[0036] The bottom diameter of the vertical rod 2 is matched with the diameter of the leak 3. When the vertical rod 2 falls to the top of the test platform 1, its bottom end is inserted into the corresponding leak 3.

[0037] By adopting the above technical solution, when it is necessary to reset the vertical rod 2 and the sleeve frame 205, the outer end of the pull rope 206 is pulled downwards. The pull rope 206 is guided and conveyed by the guide roller 207, which reduces friction. The pull rope 206 will pull the vertical rod 2 upwards on the guide rod 202 through the sleeve frame 205. When the sleeve frame 205 moves out of the top outer side of the two semicircular plates 101, the control cylinder 102 is opened, driving the two sets of semicircular plates 101 to move away from each other to the initial position. Then, the cylinder 204 is opened, driving the pressure plate 105 and pressure plate 206 to move upwards. At this time, the pull rope 206 is pulled again. At the same time, under the action of the elastic rope 203, the elastic rope 203 will gradually contract and return to its initial position. In the initial state, it further assists in moving the vertical rod 2 upward, effectively reducing the force required for manual reset by the operator and reducing labor intensity. When the vertical rod 2 moves to contact the magnet block 201, the magnetic attraction of the vertical rod 2 by the magnet block 201 cancels the tension on the pull rope 206. The setting of the protective pad 208 reduces the impact when the frame 205 falls and the noise generated by rigid collision, thus achieving protection. When the bottom end of the vertical rod 2 falls to the top of the test platform 1, it will be inserted into the outlet 3 on its lower side, improving the stability of the vertical rod 2 and allowing some of the bursting impact force to be transmitted to the test platform 1 through the vertical rod 2 for dispersion and unloading, and further limiting part of the impact force of the anti-collision barrel bursting.

[0038] Working principle: The anti-collision barrel is placed on the test platform 1. Cylinder 102 pushes two semi-circular plates 101 together to form a cylinder surrounding the barrel. Cylinder 204 pushes pressure plate 105, which, through a heavy-duty spring 107, causes pressure plate 206 to move downwards. During its downward movement, pressure plate 206 contacts the fixing plate 204 and pushes the vertical rod 2 downwards. The vertical rod 2, after escaping the magnetic attraction of the magnet 201, falls to the top of the test platform 1 under gravity, forming a lateral limit around the outside of the barrel to prevent it from tipping over under pressure. Simultaneously, the vertical rod 2... The moving sleeve frame 205 moves down synchronously and is locked on the top of the two semicircular plates 101, radially locking the closed semicircular plates 101. After the pressure plate 2 106 enters the cylinder, a small gap is left between it and the inner wall of the semicircular plate 101 to ensure air circulation. It squeezes each inclined block 112 in sequence so that it retracts into the slot 110. After passing through, each inclined block 112 automatically resets to above the pressure plate 2 106 under the action of the elastic spring 111, forming a step-by-step limiting structure. After the pressure plate 2 106 contacts the top of the barrel, it continues to press down to apply the test load. When the barrel bursts, the impact force pushes the second pressure plate 106 upward and compresses the heavy-duty spring 107 to absorb some of the impact energy. During its upward movement, the second pressure plate 106 abuts against the bottom of the inclined block 112 at its current height, preventing the impact force from continuing upward to the first pressure plate 105 and the second cylinder 104. Simultaneously, the pen 407 leaves marks on the marking plate 405 during the upward movement of the second pressure plate 106. Fragments are blocked and intercepted by the semi-circular plate 101, and the frame 205 provides further radial locking protection for the semi-circular plate 101. If the barrel contains water or sand, the leaked medium... The contents flow into the funnel 301 through the outlet 3 on the test bench 1 and are discharged in a concentrated manner. For barrels of different specifications, the gear ring 403 is rotated to drive each set of gears 402 and the special-shaped lead screw 401 to rotate synchronously. The distance between the pressure plate 2 106 and the pressure plate 1 105 is adjusted to change the preload of the heavy-duty spring 107. After the test, the pull rope 206 is pulled to drive the sleeve frame 205 and the vertical rod 2 to reset upwards. The elastic rope 203 assists the vertical rod 2 to reset. The vertical rod 2 moves to the magnet block 201 and is magnetically attracted and fixed. The cylinder 1 102 drives the semi-circular plate 101 to reset and remove the barrel.
