[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-6 This utility model discloses a remote-controlled explosive drop test device, including a column 1 and a reinforcing plate 2 fixedly connected to the bottom of the outer surface of the column 1. The top of the column 1 is fixedly connected to a crossbeam support 3. A crossbeam 4 is fixedly connected to the right side of the crossbeam support 3. A pulley mechanism is connected to the bottom of the crossbeam 4. A drop shell 6 is connected to the bottom of the pulley mechanism.

[0022] A wing plate 601 is fixedly connected to the outer surface of the falling shell 6 near the top. A slide rail 603 is fixedly connected to the outer surface of the falling shell 6. An electromagnetic locking buckle 604 is installed on the surface of the slide rail 603. A counterweight 605 is slidably connected to the surface of the slide rail 603. A crash box 602 is provided outside the slide rail 603. The wing plate 601 and the slide rail 603 are evenly spaced. Three electromagnetic locking buckles 604 are provided and evenly distributed on the surface of the slide rail 603. The electromagnetic locking buckles 604 are controlled by a remote control switch. The crash box 602 is fixedly connected to the outer surface of the falling shell 6.

[0023] The wing plate 601 is fixed to the outer surface of the falling shell 6 near the top. During the fall of the falling shell 6, the wing plate 601 interacts with the air, forming a certain air resistance, which can reduce the shaking of the falling shell 6 and keep the falling shell 6 in a relatively stable posture, thus avoiding the impact of shell shaking on the accuracy of the test results.

[0024] The anti-collision box 602 is wrapped around the slide rail 603. When the falling shell 6 falls or is accidentally hit during the test, the anti-collision box 602 can first withstand the impact force and distribute the impact force to the overall structure of the falling shell 6, so as to prevent the slide rail 603 and the counterweight 605 from being directly damaged by the impact, protect the integrity of the counterweight adjustment system, and ensure that subsequent tests can be carried out normally.

[0025] The pulley mechanism includes a driver 5, a lifter 501, a pulley block 502, a chain 503, a wheel frame 504, a solenoid valve 505, a hanging ring 506, and a hook 507. The pulley block 502 is slidably connected to the outer surface of the crossbeam 4. The lifter 501 is connected to the side of the pulley block 502. The driver 5 is fixedly installed on the top of the lifter 501. The chain 503 is connected to the bottom of the lifter 501. The wheel frame 504 is fixedly connected to the bottom end of the chain 503. The solenoid valve 505 is installed on the side of the wheel frame 504. The hanging ring 506 is movably connected to the bottom of the wheel frame 504. The hook 507 is fixedly connected to the top of the falling housing 6. There are two hanging rings 506, which are symmetrically distributed. The driver 5 and the lifter 501 are controlled by a remote control switch.

[0026] The top of the crossbeam support 3 is fixedly connected to a connecting plate 301, the bottom of the crossbeam support 3 is fixedly connected to a connecting plate 302, the column 1 passes through the connecting plate 302 and is fixedly connected to the bottom of the connecting plate 301, and the outer surface of the crossbeam support 3 is connected to a steel wire rope 303 that is connected to the upper surface of the crossbeam 4.

[0027] The explosive to be tested is carefully placed inside the drop casing 6, ensuring that it is stable and will not shift during the test. Based on the weight of the explosive and the required drop impact force, the number and position of the counterweights 605 on the sliding rail 603 are adjusted to achieve the required overall weight and center of gravity distribution for the test. After adjustment, the electromagnetic locking latch 604 is activated via a remote control switch to fix the counterweights 605 in their current positions.

[0028] Check the connections between the remote control switch and components such as driver 5, lift 501, electromagnetic lock latch 604, and solenoid valve 505 to ensure the remote control signal is stable. Test the control functions of the remote control switch on each component, such as controlling driver 5 to start and drive lift 501, controlling the opening and closing of electromagnetic lock latch 604, and controlling the on / off state of solenoid valve 505, to ensure that each component can operate accurately according to remote commands.

[0029] A comprehensive inspection of the stability of all connections within the device should be conducted, including the connections between column 1 and reinforcing plate 2, crossbeam support 3, crossbeam support 3 and crossbeam 4, connections between components of the pulley mechanism, and the connection between the lowering shell 6 and the pulley mechanism. Any loose parts should be reinforced immediately. The integrity of wire rope 303 should be checked for wear, breakage, or other defects to ensure it functions properly for reinforcement. Simultaneously, the test area should be cleared, surrounding obstacles removed, safety warning signs erected, and unauthorized personnel prohibited from entering the hazardous test area.

[0030] The drive unit 5 is activated via a remote control switch. Drive unit 5 then operates the lifting device 501, which in turn raises the wheel frame 504 and the drop housing 6 connected to the wheel frame 504 via a chain 503. During the ascent, the rising position of the drop housing 6 is monitored in real-time using a remote observation device (not explicitly mentioned in the document, but inferred here as necessary equipment for conventional remote testing). When the drop housing 6 reaches the required drop height for the test, the operation of drive unit 5 and lifting device 501 is stopped via the remote control switch. At this point, the drop housing 6 is suspended at the designated height.

[0031] After confirming that the test area is safe, the solenoid valve 505 is activated by the remote control switch. The solenoid valve 505 controls the connection between the hanging ring 506 and the wheel frame 504, causing the hanging ring 506 to separate from the wheel frame 504. This causes the hook 507 to detach from the hanging ring 506, and the falling shell 6 begins to fall freely under the action of gravity.

[0032] After the drop shell 6 falls to the test ground, wait for a period of time to ensure that the explosive is stable. Then, using remote control equipment or under safe conditions, approach the device to check the damage to the drop shell 6 and the state of the explosive after the drop test, such as whether an explosion, deformation, or leakage has occurred, and record relevant test data, such as drop height, drop time, and explosive state.

[0033] The upright column 1 is made of Q345B alloy steel, and the reinforcing plate 2 is made of Q235 steel plate. It is bolted to the ground, requiring a pull-out force of at least 10kN to enhance the connection strength between the column and the ground. The crossbeam support 3 also uses Q345B alloy steel structural components to provide stable support for the crossbeam. The crossbeam 4 uses Q345B alloy steel pipe to ensure the suspension requirements of the pulley mechanism and the lowering shell. The wire rope 303 uses a 6×19S+FC structure wire rope. The driver 5 can be a servo motor such as the 110ST-M06030 model, with a power range of 0.75-2kW and a speed of 1000-1500r / min, featuring forward / reverse rotation and braking functions to provide stable power for lifting operations. The lifting device 501 is recommended to be a SWL2.5 model ball screw jack, with a rated load of 2.5-5kN, a lifting speed of 50-100mm / s, and a transmission efficiency of not less than 85%, ensuring precise and controllable lifting of the lowering shell.

[0034] Pulley block 502 is made of cast steel, with 2-4 pulleys per block. The pulley diameter is 100-150mm, and the groove width must match the chain size. The rated load is not less than 800kg, ensuring smooth sliding and reliable load-bearing capacity. Chain 503 uses G80 grade lifting chain with a chain pitch of 16-22mm. The single link load capacity is ≥200kg, and the overall length must match the maximum drop height, with a 1-2m margin to avoid insufficient length affecting the test.

[0035] The solenoid valve 505 is a 4V210-08 model two-position two-way solenoid directional valve. The hanging ring 506 and hook 507 are forged from 40Cr alloy and the surface is carburized to ensure connection stability and durability.

[0036] The drop shell 6 is welded from Q345B steel plate, and its internal volume is adjusted according to the size of the explosive. A polyurethane buffer layer is added to the bottom to reduce the impact of the fall on the shell and the explosive. The wing plate 601 is made of 6061-T6 aluminum alloy plate to enhance stability during the descent.

[0037] The slide rail 603 uses a 45# steel guide rail to provide a smooth track for the counterweight to slide. The electromagnetic locking buckle 604 can be a DS-205 model electromagnetic lock, which has an anti-accidental locking function to ensure that the counterweight is securely fixed.

[0038] The counterweight 605 is made of cast iron and has a groove on its surface that matches the slide rail. It can be combined and stacked according to test requirements to flexibly adjust the overall weight. The anti-collision box 602 is made of ABS engineering plastic, and its protective area must cover the entire slide rail and counterweight to prevent collision damage to the components.

[0039] Working principle:

[0040] After receiving a start signal from the remote control switch, the actuator 5 converts electrical energy into mechanical energy, driving the transmission mechanism inside the lift 501. The transmission mechanism of the lift 501 drives the chain 503 to retract and extend. When the chain 503 retracts, the wheel frame 504 rises under the tension of the chain 503, thereby raising the lowering shell 6, which is connected to the wheel frame 504 via the hanging ring 506 and hook 507. When the chain 503 extends, the lowering shell 6 descends under gravity. By controlling the forward and reverse rotation and the running time of the actuator 5, precise control of the lifting height of the lowering shell 6 can be achieved.

[0041] During the suspension of the falling housing 6, the solenoid valve 505 is either de-energized or energized, depending on the type of solenoid valve. Its internal valve core is held in a specific position by the action of spring force, etc., so that the hanging ring 506 is connected to the wheel frame 504, and the hook 507 is hung on the hanging ring 506, thereby suspending the falling housing 6 stably.

[0042] When a drop test is required, the remote control switch sends an on or off signal to the solenoid valve 505. The electromagnetic coil inside the solenoid valve 505 generates a magnetic field, which attracts the valve core to overcome the spring force and other forces to move, changing the connection structure between the hanging ring 506 and the wheel frame 504, so that the hanging ring 506 can be separated from the wheel frame 504. The hook 507 loses the support of the hanging ring 506, and the falling shell 6 falls freely under the action of gravity.

[0043] The slide rail 603 provides a sliding track for the counterweight 605. By changing the position of the counterweight 605 on the slide rail 603, the overall center of gravity distribution of the falling shell 6 can be adjusted; by increasing or decreasing the number of counterweights 605, the overall weight of the falling shell 6 can be adjusted. Different center of gravity distributions and weights will affect the motion posture and impact force of the falling shell 6 during the drop process, thereby meeting the requirements of different explosive drop tests.

[0044] When the electromagnetic locking buckle 604 is not energized, its internal moving parts are in the open state under the action of springs, allowing the counterweight 605 to slide on the slide rail 603. When the electromagnetic locking buckle 604 receives the energizing signal from the remote control switch, the internal electromagnetic coil generates magnetic force, attracting the moving parts to move and firmly lock the counterweight 605 on the slide rail 603, preventing the counterweight 605 from sliding during the movement of the falling housing 6, and ensuring the stability of the test parameters.

[0045] The specific embodiments of this utility model are not intended to limit the utility model in any way. Any simple modifications, equivalent changes and alterations made to the specific embodiments based on the technical essence of this utility model shall still fall within the scope of protection of the technical solution of this utility model.
