Description

Technical Field

[0001] This application relates to the field of mine-clearing vehicle technology, and in particular to a mine-clearing device and a mine-clearing vehicle. Background Technology

[0002] Mine clearance equipment, as the primary payload of manned and unmanned mine clearance vehicles, can perform mine clearance operations and quickly clear pathways through minefields. Since mine clearance vehicles inevitably encounter impacts from mines and explosives during operations, the blast resistance of the mine clearance equipment is a key indicator of its ability to maintain operational capability after a mine detonation. If the equipment can withstand the blast, it can maintain continuous operation and improve clearance efficiency. Simultaneously, the blast-resistant design of the mine clearance equipment effectively blocks blast impacts and fragments, reducing casualties among mine clearance personnel behind the equipment and damage to the vehicle itself.

[0003] In practice, the main threats posed by landmines and other explosives are high-pressure shock waves and high-speed fragments. Regarding the threat of fragments, current mine-clearing devices primarily employ blast-resistant designs using protective plates, such as blast-proof plates, and high-strength bulletproof materials in areas potentially exposed to blast impacts to protect personnel and vehicles from fragment damage. However, this approach offers limited protection against the shock waves generated by the blast. For the threat of high-pressure shock waves, current mine-clearing devices typically utilize flexible connections in their structure. For example, they use chains or wire ropes to connect the mine-clearing components and the drive mechanism, and employ telescopic arms in their overall layout to keep the device away from the vehicle, reducing damage to the vehicle and tracks from mine explosions. However, this approach cannot protect against fragment damage, and the flexible connections only buffer a small portion of the shock wave directly acting on the chain hammer or detonator connected to the flexible component.

[0004] Therefore, how to avoid the current mine-clearing devices having a single explosion-proof method and being unable to fully resist the high-pressure shock waves and high-speed fragments generated by landmines and other explosives is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this application is to provide a mine-clearing device and a mine-clearing vehicle, which solves the problem that existing mine-clearing devices have a single blast-resistant method and cannot fully resist the high-pressure shock waves and high-speed fragments generated by landmines and other explosives.

[0006] To achieve the above objectives, this application provides a mine-clearing device, comprising:

[0007] Quick-change mechanism, used for connection to the vehicle body;

[0008] The flail mechanism includes:

[0009] Quick-change connector, for connection to the quick-change mechanism;

[0010] The yaw assembly, in rotational engagement with the quick-change connector, is used to rotate relative to the quick-change connector about an axis in a first direction;

[0011] The flail frame is rotatably engaged with the yaw assembly and is used to rotate relative to the yaw assembly about an axis perpendicular to the first direction. The flail frame is provided with a baffle.

[0012] The protective cover is rotatably attached to the flail frame;

[0013] A flexible component is attached to the side of the protective cover near the quick-change mechanism to secure the protective cover.

[0014] An elastic element, connected to the side of the protective cover away from the quick-change mechanism, is used to provide elastic force to the protective cover so that the protective cover tends to tighten the flexible element.

[0015] In some embodiments, the mine-clearing device further includes:

[0016] The connecting frame has one end hinged to the quick-change mechanism and the other end hinged to the vehicle body;

[0017] The tilting cylinder has one end hinged to the quick-change mechanism and the other end hinged to the connecting frame.

[0018] In some embodiments, the mine-clearing device further includes a pitch cylinder, one end of which is hinged to a connecting frame and the other end of which is hinged to the vehicle body.

[0019] In some embodiments, a fixed shaft is provided in the middle of the flail frame, and a bushing is provided in the middle mounting hole of the yaw assembly. The fixed shaft and the bushing are inserted and engaged so that the flail frame rotates relative to the yaw assembly with the axis of the fixed shaft as the rotation center line.

[0020] In some embodiments, the flail mechanism further includes a pin that engages with the yaw assembly, and a quick-change connector is hinged to the yaw assembly via the pin, so that the yaw assembly rotates relative to the quick-change connector about the axis of the pin as its rotation center line.

[0021] In some embodiments, the yaw assembly is provided with a mechanical limit and the quick-change connector is provided with a limiting groove. The mechanical limit and the limiting groove cooperate to limit the rotation angle range of the yaw assembly.

[0022] In some embodiments, the quick-change mechanism includes:

[0023] Quick-change structural components are equipped with pin holes;

[0024] A pin is movably disposed within a pin hole;

[0025] The handle, connected to the pin, is used to move the pin within the pin hole to lock and unlock the quick-change connector.

[0026] In some embodiments, the flail mechanism further includes:

[0027] The roller is positioned parallel to the flail frame;

[0028] A chain chain assembly, mounted on a roller;

[0029] A drive assembly, connected to the roller, is used to drive the roller to rotate.

[0030] In some embodiments, the hammer chain assembly includes a plurality of chains arranged in a double helix at a predetermined interval along the axial direction of the drum, and a hammer is connected to the end of any chain away from the drum.

[0031] This application also provides a mine-clearing vehicle, including a vehicle body and a mine-clearing device connected to the vehicle body as described above.

[0032] Compared to the aforementioned background technology, the mine-clearing device provided in this application includes a quick-change mechanism and a flail mechanism. The quick-change mechanism is used to connect to the vehicle body; the flail mechanism includes a quick-change connector, a sway assembly, a flail frame, a protective cover, a flexible element, and an elastic element. The quick-change connector is connected to the quick-change mechanism, the sway assembly is rotatably coupled to the quick-change connector, and the sway assembly is used to rotate relative to the quick-change connector about an axis in a first direction; the flail frame is rotatably coupled to the sway assembly, and the flail frame is used to rotate relative to the sway assembly about an axis in a second direction perpendicular to the first direction, and a baffle is provided on the flail frame; the protective cover is rotatably connected to the flail frame; the flexible element is connected to the side of the protective cover near the quick-change mechanism, and the flexible element is used to fix the protective cover; the elastic element is connected to the side of the protective cover away from the quick-change mechanism, and the elastic element is used to provide elastic force to the protective cover, so that the protective cover tends to tighten the flexible element.

[0033] To counter the high-speed fragments generated by the explosion, a multi-layered protection design is adopted. Specifically, the baffles on the protective cover and flail frame can withstand most of the threat of high-speed fragments, reducing the damage to the rear equipment and the vehicle body; at the same time, the multi-layered explosion-proof structure, including the flail frame, yaw assembly, and quick-change connectors, can greatly reduce the damage of high-speed fragments to the front of the vehicle body, thus forming at least two levels of protection.

[0034] To address the high-pressure shock wave generated by the explosion, a multi-stage pressure relief design is employed. Specifically, under normal conditions, the elastic force of the elastic element tauts the flexible element, fixing the protective shield relative to the flail frame. During an explosion, the shock wave acts on the protective shield, causing the elastic element to be stretched, which in turn causes the protective shield to rotate around the hinge point while simultaneously buffering and relieving pressure. At the same time, since the explosive device's location is random and unlikely to align with the flail mechanism, the explosion will generate impact torques that cause the flail mechanism to overturn both laterally and backward. The yaw assembly allows the flail frame and its associated mechanisms to rotate a certain angle in the yaw direction, thus relieving pressure. The quick-change connector allows the yaw assembly and its connected flail frame and other structures to rotate a certain angle in the backward direction, also relieving pressure. This creates at least three stages of pressure relief.

[0035] As can be seen from the above, in view of the problem that the existing mine-clearing devices have a single blast-resistant method and cannot fully resist the high-pressure shock waves and high-speed fragments generated by landmines and other explosives, this application provides a multi-stage pressure relief and multi-layer protection blast-resistant mine-clearing device. It provides multiple buffering and pressure relief for the high-pressure shock waves generated by explosives and multiple protections for high-speed fragments, forming a comprehensive and multi-layered blast-resistant protection system. This solves the problem that the existing mine-clearing devices have a single blast-resistant method and cannot fully resist the high-pressure shock waves and high-speed fragments generated by landmines and other explosives, enabling the mine-clearing device to maintain continuous operation, improving mine-clearing efficiency, and reducing personnel casualties and vehicle damage.

[0048] It should be noted that the directional terms such as "upper end," "lower end," "left side," and "right side" mentioned below are defined based on the accompanying drawings in the instruction manual.

[0049] Please refer to Figures 1 to 4 , Figure 1 This is a schematic diagram of the mine-sweeping device in the embodiments of this application. Figure 2 for Figure 1 A cross-sectional view of the mine-clearing device shown. Figure 3 for Figure 1 A schematic diagram of the structure of the quick-change mechanism. Figure 4 for Figure 2 A schematic diagram showing the connection between the hammer chain assembly and the roller.

[0050] The mine-clearing device provided in this application includes a quick-change mechanism 2 and a flail mechanism 1.

[0051] The quick-change mechanism 2 is used to connect with the vehicle body. At the same time, the quick-change mechanism 2 is connected to the flail mechanism 1 through a connector.

[0052] The flail mechanism 1 includes a quick-change connector 20, a swing assembly 17, and a flail frame 10.

[0053] The quick-change connector 20 (also called quick-change interface) is connected to the quick-change mechanism 2. The sway assembly 17 is rotatably engaged with the quick-change connector 20. The sway assembly 17 is used to rotate relative to the quick-change connector 20 about the axis of the first direction. The flail frame 10 is rotatably engaged with the sway assembly 17. The flail frame 10 is used to rotate relative to the sway assembly 17 about the axis of the second direction perpendicular to the first direction. The flail frame 10 is provided with a baffle.

[0054] It should be noted that the first direction mentioned above is the transverse direction of the flail mechanism 1, and the second direction is the longitudinal direction of the flail mechanism 1. The rotation of the yaw component 17 around the transverse axis is used to resist the shock wave that would cause the mechanism to overturn backward, and the rotation of the flail frame 10 around the longitudinal axis is used to resist the shock wave that would cause the mechanism to overturn sideways.

[0055] Meanwhile, the flail mechanism 1 also includes a protective cover 21, a flexible component 23, and an elastic component 22.

[0056] The protective cover 21 is rotatably connected to the flail frame 10; the flexible member 23 is connected to the side of the protective cover 21 near the quick-change mechanism 2, and the flexible member 23 is used to fix the protective cover 21; the elastic member 22 is connected to the side of the protective cover 21 away from the quick-change mechanism 2, and the elastic member 22 is used to provide elastic force to the protective cover 21 so that the protective cover 21 tends to tighten the flexible member 23.

[0057] Of course, depending on actual needs, the above-mentioned protective cover 21 can be an arc-shaped protective cover or a bent protective cover, the elastic element 22 is a tension spring, and the flexible element 23 can be a chain or a steel wire rope.

[0058] Specifically, the upper surface of the flail frame 10 is connected to the protective cover 21 via a hinge. The rotation of the protective cover 21 relative to the flail frame 10 is restricted by the elastic element 22 on the front side and the flexible element 23 on the rear side of the protective cover 21. Under normal conditions, the tension of the elastic element 22 tightens the flexible element 23, fixing the protective cover 21 relative to the flail frame 10. During an explosion, the shock wave generated by the explosion acts on the protective cover 21, and the elastic element 22 is stretched, causing the protective cover 21 to rotate around the hinge point while buffering and dissipating the shock wave.

[0059] Set it up like this:

[0060] To counter the high-speed fragments generated by the explosion, a multi-layered protective design is adopted. Specifically, the baffles on the protective cover 21 and the flail frame 10 can withstand most of the threat of high-speed fragments, reducing the damage to the rear equipment and the vehicle body; at the same time, the multi-layered explosion-proof structure, including the flail frame 10, the sway assembly 17, and the quick-change connector 20, can greatly reduce the damage of high-speed fragments to the front of the vehicle body, thus forming at least two levels of protection.

[0061] To address the high-pressure shock wave generated by the explosion, a multi-stage pressure relief design is employed. Specifically, under normal conditions, the elastic force of the elastic element 22 tightens the flexible element 23, fixing the protective cover 21 relative to the flail frame 10. During an explosion, the shock wave generated by the explosion acts on the protective cover 21, and the elastic element 22 is stretched, causing the protective cover 21 to rotate around the hinge point while simultaneously buffering and relieving pressure. At the same time, since the explosive device explodes at random locations, it is highly unlikely to align with the flail mechanism 1. During the explosion, impact torques that cause the flail mechanism 1 to overturn laterally and backward will be generated simultaneously. The sway assembly 17 can rotate the flail frame 10 and its associated mechanisms at a certain angle in the direction of lateral overturning to achieve pressure relief. The quick-change connector 20 can rotate the sway assembly 17 and its connected structures such as the flail frame 10 at a certain angle in the direction of backward overturning to achieve pressure relief, thus forming at least three stages of pressure relief.

[0062] As can be seen from the above, in view of the problem that the existing mine-clearing devices have a single blast-resistant method and cannot fully resist the high-pressure shock waves and high-speed fragments generated by landmines and other explosives, this application provides a multi-stage pressure relief and multi-layer protection blast-resistant mine-clearing device. It provides multiple buffering and pressure relief for the high-pressure shock waves generated by explosives and multiple protections for high-speed fragments, forming a comprehensive and multi-layered blast-resistant protection system. This solves the problem that the existing mine-clearing devices have a single blast-resistant method and cannot fully resist the high-pressure shock waves and high-speed fragments generated by landmines and other explosives, enabling the mine-clearing device to maintain continuous operation, improving mine-clearing efficiency, and reducing personnel casualties and vehicle damage.

[0063] In some embodiments, the mine-clearing device further includes a connecting frame 3 and a tilting cylinder 4.

[0064] One end of the connecting frame 3 is hinged to the quick-change mechanism 2, and the other end is hinged to the vehicle body; one end of the tilting cylinder 4 is hinged to the quick-change mechanism 2, and the other end is hinged to the connecting frame 3.

[0065] Specifically, one end of the connecting frame 3 is hinged to the quick-change mechanism 2 via two side pins, and the other end of the vehicle body is hinged via a pin; the two ends of the tilting cylinder 4 are respectively hinged to the middle hinge seat of the quick-change mechanism 2 and the middle hinge seat of the connecting frame 3 via pins.

[0066] In this way, a connecting frame 4 is set between the flail mechanism 1 and the vehicle body, which serves as a mechanical interface for connection and quick replacement, and also increases the distance between the flail mechanism 1 and the vehicle body, further reducing the damage to the vehicle body caused by landmine explosions.

[0067] In some embodiments, the mine-clearing device further includes a pitch cylinder 5, one end of which is hinged to the connecting frame 3, and the other end is used to hinge to the vehicle body.

[0068] It should be noted that the pitch cylinder 5 adopts a floating mode during mine clearance operations, with the cylinder in a depressurized state. The flail mechanism 1 contacts the ground under natural gravity. In the event of an explosion, the pitch cylinder 5 can retract, and the flail mechanism 1 rotates relative to the vehicle body to depressurize, with the hinge center line between the connecting frame 3 and the vehicle body as the axis.

[0069] To facilitate the rotational engagement of the flail frame 10 and the yaw assembly 17, a fixed shaft is provided in the middle of the flail frame 10, and a bushing 16 is provided in the mounting hole in the middle of the yaw assembly 17. The fixed shaft and the bushing 16 are inserted into each other so that the flail frame 10 rotates relative to the yaw assembly 17 with the axis of the fixed shaft as the rotation center line.

[0070] Specifically, a fixed shaft is provided at the symmetrical axis in the middle of the flail frame 10. The fixed shaft protrudes from the end face where the flail frame 10 is located. A swing assembly 17 is arranged behind the flail frame 10. A bushing 16 is fitted into the mounting hole in the center of the swing assembly 17. After the fixed shaft in the middle of the flail frame 10 is inserted into the bushing 16, it is fixed by the end cap 18 and bolts and connected to the swing assembly 17, so that the flail frame 10 can rotate relative to the swing assembly 17 with the fixed shaft as the rotation center.

[0071] In this way, in response to the impact torque that would cause the flail mechanism 1 to overturn during an explosion, the yaw component 17 can rotate the flail frame 10 and its associated mechanism at a certain angle along the longitudinal rotation center to achieve buffering and pressure relief.

[0072] To facilitate the rotational engagement of the yaw assembly 17 and the quick-change connector 20, the flail mechanism 1 also includes a pin 19, which is engaged with the yaw assembly 17. The quick-change connector 20 is hinged to the yaw assembly 17 via the pin 19, so that the yaw assembly 17 rotates relative to the quick-change connector 20 with the axis of the pin 19 as the rotation center line.

[0073] Specifically, the yaw assembly 17 is hinged to the quick-change connector 20 at the rear by a pin 19 passing through pin holes on the top left and right sides, so that the yaw assembly 17 can rotate relative to the quick-change connector 20 with the pin 19 as the rotation center.

[0074] In this way, in response to the impact torque that would cause the flail mechanism 1 to overturn during an explosion, the quick-change connector 20 can rotate the yaw assembly 17 and its connected flail frame 10 and other structures by a certain angle along the lateral rotation center to achieve buffering and pressure relief.

[0075] In some embodiments, the yaw assembly 17 is provided with a mechanical limit, such as a limit block. Correspondingly, the quick-change connector 20 is provided with limit grooves on both sides. The mechanical limit and the limit groove limit each other to limit the rotation angle range of the yaw assembly 17, thereby limiting the yaw angle range as needed.

[0076] In some embodiments, the quick-change mechanism 2 includes a quick-change structural member 41 (also called a quick-change weldment), a pin 42, and a handle 43.

[0077] The quick-change structural component 41 is provided with a pin hole; the pin 42 is movably disposed in the pin hole; the handle 43 is connected to the pin 42, and the handle 43 is used to drive the pin 42 to move in the pin hole so as to realize the locking and unlocking of the quick-change mechanism 2 and the quick-change connector 20.

[0078] Specifically, the pin 42 is arranged in the pin holes on the lower left and right sides of the quick-change structure 41. The handle 43 is connected to the pin 42 through a connecting rod. Rotating the handle 43 can drive the pin 42 to move up and down in the pin hole below the quick-change structure 41, so as to realize the quick locking and unlocking of the quick-change component 2 and the quick-change connector 20 on the flail mechanism 1.

[0079] In some embodiments, the flail mechanism 1 further includes a roller 11, a chain assembly 12, and a drive assembly.

[0080] The roller 11 is arranged parallel to the flail frame 10; the hammer chain assembly 12 is installed on the roller 11; the drive assembly is connected to the roller 11 and is used to drive the roller 11 to rotate so that the hammer chain assembly 12 can perform mine-clearing operations.

[0081] Specifically, the drive assembly includes a belt drive assembly 13 and a flail motor 14. The belt drive assembly 13 is installed in the left and right housings of the flail frame 10. The belt drive assembly 13 includes a drive pulley connected to the flail motor 14, a driven pulley connected to one end of the roller 11, and a belt tensioned on both the drive pulley and the driven pulley. In this way, the flail motor 14 provides rotational power to drive the roller 11 to rotate via the belt drive assembly 13.

[0082] In this embodiment, the hammer chain assembly 12 includes a plurality of chains 31, which are arranged in a double spiral at a preset interval along the axial direction of the roller 11, and a chain hammer 32 is connected to the end of any chain 31 away from the roller 11.

[0083] As can be seen, the double-helix chain 31 drives the chain hammer 32 to form a three-dimensional mine-sweeping trajectory, covering the entire axial range of the drum 11 and eliminating the axial mine-sweeping blind zone of the traditional single-row chain. At the same time, the double-helix symmetrical structure cancels out the axial component force of the single-helix arrangement, making the drum 11 stress-balanced and reducing the risk of bearing wear. Of course, the helical distribution of the chain 31 also optimizes the phase difference of the instantaneous impact load and reduces the rotational resistance torque of the drum 11.

[0084] In addition, the mine-clearing device also includes slipper assemblies 15 installed on the lower ends of both sides of the flail frame 10, which are used to support the flail mechanism 1 during mine-clearing.

[0085] In summary:

[0086] Multi-stage pressure relief is achieved through the following structure:

[0087] 1. Since the overpressure of the high-pressure shock wave decreases exponentially with distance, this application adopts an extended chain 31 to increase the distance from the landmine explosion point to the flail mechanism 1 and the vehicle body, so that the high-pressure shock wave decreases rapidly with distance and achieves the first stage of pressure relief.

[0088] 2. The protective cover 21 of the flail mechanism 1 is connected by a flexible component 23, a hinge and an elastic component 22. During an explosion, it can rotate around the hinge point while buffering and venting the wave, thus achieving a second-stage depressurization.

[0089] 3. The explosive device detonates randomly and is unlikely to align with the flail mechanism 1. The explosion will simultaneously generate impact torques that cause the flail mechanism 1 to overturn both laterally and backward. The yaw assembly 17 allows the flail frame 10 and its associated rollers 11 to rotate a certain angle along the overturning direction, achieving a third-stage pressure relief.

[0090] 4. The quick-change connector 20 allows the yaw assembly 17 and its connected flail frame 10 and other structures to rotate a certain angle in the backward direction to release pressure, thus achieving the fourth stage of pressure relief.

[0091] 5. When the pitch cylinder 5 is in mine-clearing operation, it adopts floating mode and the cylinder is in depressurization state. The flail mechanism 1 is in contact with the ground under natural gravity. In the event of an explosion, the pitch cylinder 5 can retract and the flail mechanism 1 rotates relative to the vehicle body to depressurize around the hinge center line between the connecting frame 3 and the vehicle body. This is the fifth stage of depressurization.

[0092] 6. A connecting frame 4 is installed between the flail mechanism 1 and the vehicle body. This serves as a mechanical interface for connection and quick replacement, and also increases the distance between the flail mechanism 1 and the vehicle body, further reducing the damage to the vehicle body caused by landmine explosions. This is the sixth-stage pressure relief device.

[0093] After multiple layers of depressurization, the impact of the explosive product will be buffered and dissipated layer by layer, greatly reducing the damage of the shock wave overpressure to the flail mechanism 1 and the vehicle body.

[0094] Multi-layered protection is achieved through the following structure:

[0095] 1. The protective cover 21 of the flail mechanism 1 and the front baffle of the flail frame 10 are both made of bulletproof steel plates, which can withstand most of the threats of high-speed fragments and reduce the damage to the rear device and the vehicle body. This is the first level of protection.

[0096] 2. The flail mechanism 1 adopts a multi-layer explosion-proof structure, including a flail frame 10, a sway assembly 17, and a quick-change connector 20, which can greatly reduce the damage of high-speed fragments to the front of the vehicle body. This is the second level of protection.

[0097] 3. The mine-clearing device has two layers of protection, which, together with the bulletproof steel plate placed at the front of the vehicle body, can effectively block damage from high-speed fragments.

[0098] The mine-clearing vehicle provided in this application includes a vehicle body and a mine-clearing device connected to the vehicle body as described in the specific embodiments above; other parts of the mine-clearing vehicle can be referred to in related technologies, and will not be elaborated here.
