Description

Technical Field

[0001] This utility model relates to the military field, specifically to an anti-recoil top-removal device for armored vehicles. Background Technology

[0002] In the routine maintenance and battlefield use of armored vehicles, the recoil mechanism, as a crucial component of the vehicle's main gun, directly impacts the vehicle's overall combat capability. When the recoil mechanism malfunctions or needs replacement, the disassembly and assembly process typically presents significant technical challenges. On one hand, the recoil mechanism has a complex structure, and its installation location is usually in a confined space, making it difficult to apply sufficient force for disassembly using traditional tools. On the other hand, the recoil mechanism is made of high-strength materials, and the connections between components are tight, making it easy for improper force application during disassembly and assembly to cause damage to parts or operational errors.

[0003] In existing technologies, hydraulic jacking devices or traditional hand tools are typically used to solve the problem of disassembling and assembling the recoil mechanism. However, these methods have the following problems:

[0004] Limitations of hydraulic systems: While hydraulic jacking devices can provide significant jacking force, their large size makes them unsuitable for operation within the confined spaces of armored vehicles. Furthermore, hydraulic systems are complex to operate, have high maintenance costs, require an external power source, and are unsuitable for certain field environments.

[0005] Traditional hand tools are inefficient: Tools such as bolt wrenches and pry bars have low force transmission efficiency, making it difficult to apply high torque precisely. Furthermore, they are prone to causing device misalignment or operational failure during the assembly and disassembly of recoil mechanisms. In addition, the operation of hand tools relies heavily on the operator's experience and skill level, resulting in poor operational stability. Summary of the Invention

[0006] To solve the above-mentioned technical problems, this utility model provides an anti-recoil top-removal device for armored vehicles.

[0007] This utility model is achieved through the following technical solution:

[0008] This utility model discloses an anti-recoil top-removal device for armored vehicles, comprising:

[0009] Recoil-reducing connector for use with the anti-recoil device of armored vehicles;

[0010] The sleeve is fixedly connected to the aforementioned anti-recoil connector;

[0011] A lead screw with one end set inside the aforementioned sleeve and arranged coaxially with the aforementioned sleeve;

[0012] A ratchet drive mechanism installed on the aforementioned sleeve to drive the aforementioned lead screw to rotate;

[0013] A force-applying seat is fixedly connected to the aforementioned ratchet drive mechanism;

[0014] A top seat is fixedly connected to the lead screw at the end away from the anti-back-seat connector.

[0015] The key to this device lies in the linkage between the ratchet drive mechanism and the lead screw to generate a controllable jacking force, enabling the rapid and safe assembly and disassembly of the anti-recoil device on armored vehicles. The anti-recoil connector is the foundation for connecting this device to the anti-recoil device on the armored vehicle, while the sleeve provides the main guidance and support. Through the extension and retraction of the lead screw, the jacking seat transmits the jacking force to the target component, achieving controlled disassembly. This device is designed with simplicity in structure and ease of use in mind, while also being adaptable to assembly and disassembly requirements in various environments.

[0016] Furthermore, the aforementioned anti-recoil connector includes a connecting cylinder and a connecting seat; two connecting cylinders are provided and are fixedly connected to the connecting seat in a mirror-symmetrical arrangement; the connecting seat is a rectangular plate-shaped piece, one side of which is fixedly connected to the sleeve, and the other side is connected to the two connecting cylinders; the connecting seat is arranged perpendicular to the central axis of the sleeve; the central axis of the connecting cylinder is arranged perpendicular to the central axis of the sleeve.

[0017] The recoil-recoil connector consists of two connecting cylinders and a connecting seat, ensuring a reliable connection between the device and the armored vehicle's recoil-recoil mechanism. The mirror-symmetric layout of the connecting cylinders ensures even force distribution on the connecting seat, preventing excessive load in one direction. One side of the connecting seat is fixedly connected to the sleeve, while the other side connects to the two connecting cylinders, forming a stable mechanical unit. This structure ensures that the connection will not loosen or shift due to high-intensity upward forces during operation.

[0018] Furthermore, the aforementioned connecting cylinder is a hollow cylindrical component with openings at both ends. The open-end design allows for quick insertion into the fixing pins of armored vehicles, facilitating rapid installation. Its hollow cylindrical structure reduces weight while meeting strength requirements. The central axes of the connecting cylinder and the sleeve are arranged perpendicularly, which helps balance the load transmitted from the recoil device, reduces the risk of stress concentration, and extends component life.

[0019] Furthermore, the aforementioned sleeve includes:

[0020] The cylinder body is connected to the aforementioned anti-recoil connector;

[0021] A lubrication chamber is located on the cylinder body at the end away from the anti-recoil connector; the lubrication chamber is fitted and connected to the lower side of the ratchet drive mechanism;

[0022] A dust cover is fitted to the upper side of the ratchet drive mechanism.

[0023] The sleeve achieves functional integration of its structure through the sleeve body, lubrication chamber, and dust cover. The lubrication chamber, located on the sleeve body, lubricates the contact surfaces between the lead screw and the inside of the sleeve, ensuring smooth extension and retraction of the lead screw. The dust cover, located above the lubrication chamber, acts as a physical barrier to prevent external dust from entering the lubrication system, thereby protecting the internal components from the influence of the external environment.

[0024] Furthermore, the aforementioned lubrication chamber is a hollow cylindrical shape, coaxially arranged with the main body of the cylinder. The function of this hollow cylindrical lubrication chamber is to reduce friction and minimize wear on the leadscrew by using lubricant. This design allows the lubricant to be evenly distributed between the inner walls of the leadscrew and the sleeve, reducing mechanical losses during component movement. The coaxial arrangement of the lubrication chamber also facilitates centralized storage of the lubricant, preventing uneven lubrication caused by device tilting.

[0025] Furthermore, one end of the aforementioned lead screw is disposed inside the aforementioned sleeve, and the other end passes through the ratchet drive mechanism and is connected to the top seat; the aforementioned lead screw can extend or retract along the direction of the central axis of the sleeve under the drive of the ratchet drive mechanism.

[0026] One end of the lead screw is housed inside the sleeve, and the other end is connected to the top seat via a ratchet drive mechanism. Driven by the ratchet drive mechanism, the lead screw moves along the central axis of the sleeve, realizing the extension and retraction of the top seat. Through the rotational thread transmission of the lead screw, the device can generate a large pushing force within a limited space, thereby meeting the requirements for the assembly and disassembly of the anti-recoil device of armored vehicles.

[0027] Furthermore, the aforementioned ratchet drive mechanism includes:

[0028] Ring-shaped ratchet;

[0029] A rotating drum is fixedly connected coaxially to the aforementioned annular ratchet; the inner wall of the rotating drum is provided with a thread that mates with the lead screw;

[0030] A U-shaped retainer is engaged at both ends of the aforementioned annular ratchet.

[0031] The fork is pinned to the cage and can rotate horizontally. The fork is V-shaped, with two fork-like branches at the upper end of the V-shape for turning the annular ratchet, and the lower end of the V-shape is the bottom.

[0032] A top cone is fitted at the bottom of the aforementioned shift fork; the aforementioned top cone has a tendency to move toward the annular ratchet, lifting the shift fork and causing the shift fork to swing to its limit position in a certain direction;

[0033] A compression spring, with one end connected to the aforementioned top cone and the other end fixed, provides elastic force to the top cone.

[0034] The reversing handle, which is fixedly connected to the aforementioned shift fork, can overcome the spring force of the top cone under the operator's rotation operation, allowing the shift fork to move from one extreme position to another.

[0035] The housing encapsulates the aforementioned cage and shift fork, and provides physical limits for the two extreme positions of the shift fork.

[0036] The core of the ratchet drive mechanism is the engagement between the annular ratchet and the rotating drum. The teeth of the annular ratchet mesh with the shift fork, and the oscillation of the shift fork drives the annular ratchet to rotate in one direction. The inner thread of the rotating drum matches the lead screw, and when the annular ratchet rotates, it drives the lead screw to move along the central axis. The design of the reversing handle allows the shift fork to switch extreme positions, thereby changing the rotation direction of the annular ratchet and realizing the extension and retraction adjustment of the lead screw.

[0037] Furthermore, when the aforementioned fork is in a certain extreme position, one fork-shaped part of the fork is located between two adjacent ratchet teeth of the annular ratchet. At this time, rotating the retainer in one direction can drive the annular ratchet to rotate, while rotating it in the other direction cannot drive the annular ratchet to move.

[0038] The shift fork is held at a certain extreme position by the elastic force provided by the compression spring. When the fork-shaped part of the shift fork is between the ratchet teeth of the ring ratchet, the unidirectional rotation of the cage can drive the ring ratchet to work. By operating the reversing handle, the shift fork can overcome the elastic force of the compression spring and switch from one extreme position to another, completing the reversing adjustment of the ratchet drive mechanism.

[0039] Furthermore, the rotation direction of the aforementioned cage is arranged perpendicular to the central axis of the sleeve; the aforementioned force-applying seat is fixedly connected to the outer shell and can be temporarily fixedly connected to the force-applying rod.

[0040] The force-adjusting seat is fixedly connected to the housing and can be used in conjunction with the force-adjusting rod during operation to provide additional torque support for the operator. The temporary fixing design of the force-adjusting seat facilitates quick assembly and disassembly, while its position ensures that the applied force is consistent with the direction of movement of the lead screw, avoiding wasted torque.

[0041] Furthermore, the aforementioned top seat is a rectangular plate-shaped component. As the end component of the device, the top seat is fixedly connected to the lead screw and is used to apply the jacking force transmitted by the lead screw to the target component. The rectangular plate-shaped design provides a large contact surface, thereby ensuring that the top seat will not damage the surface of the target component when applying jacking force, while effectively distributing the load and further improving the operational reliability of the device.

[0042] This utility model proposes an anti-recoil top-removal device for armored vehicles, which has the following significant advantages compared with the prior art:

[0043] With its compact and highly adaptable design, this device employs a modular design. Through the flexible combination of anti-recoil connectors and sleeves, it can be adapted to anti-recoil devices of various armored vehicle models, meeting the different vehicle assembly and disassembly requirements. Furthermore, its small overall size makes it suitable for operation within the limited space inside armored vehicles, significantly improving operational convenience.

[0044] Simple to operate and convenient to use, this device requires no additional power source and can complete complex disassembly and assembly tasks by manual operation alone. The ratchet drive mechanism controls the extension and retraction of the lead screw through the reversing handle. The operator only needs to rotate the force-applying rod to easily achieve a large jacking force output, significantly reducing the difficulty of operation and improving efficiency.

[0045] With controllable jacking force and safe operation, the device maintains stable jacking force under any operating condition through the self-locking characteristics of the lead screw and ratchet drive mechanism, avoiding damage or accidents caused by unexpected rebound. At the same time, the design of the top seat provides a large force-bearing surface, which can effectively distribute the load and prevent the target component from being damaged due to excessive local stress.

[0046] Highly durable and with low maintenance costs, the lubrication chamber and dust cover design of this device effectively reduce frictional loss between the lead screw and the inner wall of the sleeve, extending the service life of the device. The lubrication system has excellent sealing performance, maintaining the operational stability of the device in complex environments and significantly reducing maintenance costs and operational risks.

[0047] With its high versatility and wide applicability, this device is not only suitable for disassembling recoil mechanisms but also for installing and securing other armored vehicle components. Its adjustable torque output enables it to handle various types of mechanical assembly and disassembly tasks, making it widely applicable in both battlefield and maintenance station environments.

[0048] In summary, this utility model overcomes various problems existing in the prior art through structural optimization and functional design, and significantly improves the disassembly and assembly efficiency, safety and applicability of the anti-recoil device for armored vehicles, which has important practical significance and promotional value.

Detailed Implementation

[0060] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0061] Example: Figure 1-10 As shown, an anti-recoil top-removal device for armored vehicles includes:

[0062] Recoil-recoil connector 1, which connects to the anti-recoil device of an armored vehicle;

[0063] Sleeve 2 is fixedly connected to the aforementioned anti-recoil connector 1;

[0064] One end is set inside the sleeve 2 and the lead screw 3 is arranged coaxially with the sleeve 2;

[0065] A ratchet drive mechanism 4 is installed on the sleeve 2 and drives the lead screw 3 to rotate.

[0066] A force-applying seat 5 is fixedly connected to the ratchet drive mechanism 4 described above;

[0067] The top seat 6 is fixedly connected to the lead screw 3 at the end away from the anti-back-seat connector 1.

[0068] The key to this device lies in the linkage between the ratchet drive mechanism 4 and the lead screw 3 to generate a controllable jacking force, enabling the rapid and safe assembly and disassembly of the anti-recoil device on armored vehicles. The anti-recoil connector 1 forms the basis for connecting the device to the anti-recoil device on the armored vehicle, while the sleeve 2 provides the main guidance and support. Through the extension and retraction of the lead screw 3, the top seat 6 transmits the jacking force to the target component, achieving controlled disassembly. This device is designed with simplicity in structure and ease of use in mind, while also being adaptable to the assembly and disassembly requirements of various environments.

[0069] Furthermore, the aforementioned anti-recoil connector 1 includes a connecting cylinder 11 and a connecting seat 12; two connecting cylinders 11 are provided and are fixedly connected to the connecting seat 12 in a mirror-symmetrical arrangement; the connecting seat 12 is a rectangular plate-shaped piece, one side of which is fixedly connected to the sleeve 2, and the other side is connected to the two connecting cylinders 11; the connecting seat 12 is arranged perpendicular to the central axis of the sleeve 2; the central axis of the connecting cylinder 11 is arranged perpendicular to the central axis of the sleeve 2.

[0070] The anti-recoil connector 1 consists of two connecting cylinders 11 and a connecting seat 12, ensuring a reliable connection between the device and the anti-recoil device of the armored vehicle. The mirror-symmetric layout of the connecting cylinders 11 ensures a uniform force distribution on the connecting seat 12, avoiding excessive load in one direction. One side of the connecting seat 12 is fixedly connected to the sleeve 2, and the other side is connected to the two connecting cylinders 11, forming a stable mechanical unit. This structure ensures that the connection will not loosen or shift due to high-intensity upward forces during operation.

[0071] Furthermore, the aforementioned connecting cylinder 11 is a hollow cylindrical component with openings at both ends. The open-end design of the connecting cylinder 11 allows for quick insertion into the fixing pin of the armored vehicle, facilitating rapid installation of the device. Its hollow cylindrical structure reduces weight while meeting strength requirements. The connecting cylinder 11 is arranged perpendicularly to the central axis of the sleeve 2, which helps to balance the load transmitted from the recoil device, reduce the risk of stress concentration, and extend the component's lifespan.

[0072] Furthermore, the aforementioned sleeve 2 includes:

[0073] The cylinder body 21 is connected to the aforementioned anti-recoil connector 1;

[0074] A lubrication chamber 22 is disposed on the cylinder body 21 at the end away from the anti-recoil connector 1; the lubrication chamber 22 is fitted and connected to the lower side of the ratchet drive mechanism 4;

[0075] A dust cover 23 is fitted and connected to the upper side of the ratchet drive mechanism 4.

[0076] The sleeve 2 achieves functional integration of its structure through the sleeve body 21, lubrication chamber 22, and dust cover 23. The lubrication chamber 22 is located on the sleeve body 21 and is used to lubricate the contact surface between the lead screw 3 and the inside of the sleeve, ensuring smooth extension and retraction of the lead screw 3. The dust cover 23 is located above the lubrication chamber 22 and prevents external dust from entering the lubrication system through a physical barrier, thereby protecting the internal parts from the influence of the external environment.

[0077] Furthermore, the aforementioned lubrication chamber 22 is a hollow cylindrical shape, coaxially arranged with the main body 21. The function of the lubrication chamber 22, being a hollow cylindrical shape and coaxially arranged with the main body 21, is to reduce friction and decrease wear on the lead screw 3 by using lubricant. This design allows the lubricant to be evenly distributed between the inner walls of the lead screw 3 and the sleeve 2, reducing mechanical losses during component movement. The coaxial arrangement of the lubrication chamber 22 facilitates centralized storage of the lubricant, preventing uneven lubrication caused by device tilting.

[0078] Furthermore, one end of the aforementioned lead screw 3 is disposed inside the aforementioned sleeve 2, and the other end passes through the ratchet drive mechanism 4 and is connected to the top seat 6; the aforementioned lead screw 3 can extend or retract along the direction of the central axis of the sleeve 2 under the drive of the ratchet drive mechanism 4.

[0079] One end of the lead screw 3 is located inside the sleeve 2, and the other end is connected to the top seat 6 via a ratchet drive mechanism 4. Driven by the ratchet drive mechanism 4, the lead screw 3 moves along the central axis of the sleeve 2, realizing the extension and retraction of the top seat 6. Through the rotational thread transmission of the lead screw, the device can generate a large pushing force within a limited space, thereby meeting the requirements for the assembly and disassembly of the anti-recoil device of armored vehicles.

[0080] Furthermore, the aforementioned ratchet drive mechanism 4 includes:

[0081] 41-ring ratchet;

[0082] A rotating drum 42 is coaxially and fixedly connected to the aforementioned annular ratchet 41; the inner wall of the rotating drum 42 is provided with a thread that mates with the lead screw 3;

[0083] A U-shaped retainer 43 is engaged at both ends of the aforementioned annular ratchet 41;

[0084] The fork 44 is pinned to the retainer 43 and can rotate horizontally. The fork 44 is V-shaped, with two branches at the upper end of the V-shape as fork-like parts for turning the annular ratchet 41, and the lower end of the V-shape as the bottom.

[0085] A top cone 45 is fitted at the bottom of the aforementioned shift fork 44; the aforementioned top cone 45 has a tendency to move toward the annular ratchet 41, lifting the shift fork 44 and causing the shift fork 44 to swing to its limit position in a certain direction.

[0086] A compression spring 46, with one end connected to the aforementioned top cone 45 and the other end fixed, provides elastic force to the top cone 45.

[0087] The reversing handle 47, which is fixedly connected to the aforementioned shift fork 44, can overcome the elastic force of the top cone 45 under the operator's rotation operation, allowing the shift fork 44 to move from one extreme position to another.

[0088] The housing 48 encapsulates the aforementioned retainer 43 and shift fork 44, and provides physical limits for the two extreme positions of the shift fork 44.

[0089] The core of the ratchet drive mechanism 4 is the engagement between the annular ratchet 41 and the rotating cylinder 42. The teeth of the annular ratchet 41 engage with the shift fork 44, and the oscillation of the shift fork 44 drives the annular ratchet 41 to rotate in one direction. The inner thread of the rotating cylinder 42 matches the lead screw 3, and when the annular ratchet 41 rotates, it drives the lead screw 3 to move along the central axis. The design of the reversing handle 47 allows the shift fork 44 to switch extreme positions, thereby changing the rotation direction of the annular ratchet 41 and realizing the extension and retraction adjustment of the lead screw 3.

[0090] Furthermore, when the aforementioned shift fork 44 is in a certain extreme position, one fork-shaped part of the shift fork 44 is located between two adjacent ratchet teeth of the annular ratchet 41. At this time, rotating the retainer 43 in one direction can drive the annular ratchet 41 to rotate, while rotating it in the other direction will not drive the annular ratchet 41 to move.

[0091] The shift fork 44 is held at a certain extreme position by the elastic force provided by the compression spring 46. When the fork-shaped part of the shift fork 44 is between the ratchet teeth of the ring ratchet 41, the unidirectional rotation of the retainer 43 can drive the ring ratchet 41 to work. By operating the reversing handle 47, the shift fork 44 can overcome the elastic force of the compression spring 46 and switch from one extreme position to another, completing the reversing adjustment of the ratchet drive mechanism 4.

[0092] Furthermore, the rotation direction of the aforementioned retainer 43 is arranged perpendicular to the central axis of the sleeve 2; the aforementioned force-applying seat 5 is fixedly connected to the outer casing 48 and can be temporarily fixedly connected to the force-applying rod.

[0093] The force-applying seat 5 is fixedly connected to the housing 48 and can be used in conjunction with the force-applying rod during operation to provide additional torque support for the operator. The temporary fixing design of the force-applying seat 5 facilitates quick assembly and disassembly, while its position selection ensures that the applied force is consistent with the movement direction of the lead screw 3, avoiding wasted torque.

[0094] Furthermore, the aforementioned top seat 6 is a rectangular plate-shaped component. As the end component of the device, the top seat 6 is fixedly connected to the lead screw 3 and is used to apply the jacking force transmitted by the lead screw 3 to the target component. The rectangular plate-shaped design provides a large contact surface, thereby ensuring that the top seat 6 will not damage the surface of the target component when applying jacking force, while effectively distributing the load and further improving the operational reliability of the device.

[0095] The following is a detailed description of the workflow of this utility model:

[0096] 1. Device Connection and Initialization

[0097] During the maintenance of the recoil reduction device of a certain type of armored vehicle, it is necessary to use this armored vehicle recoil reduction disassembly device to remove the recoil reduction device. First, the recoil reduction connector 1 is connected to the fixed interface of the armored vehicle recoil reduction device through two connecting cylinders 11, and the connection is fixed by pins to ensure that the connecting seat 12 of the recoil reduction connector 1 is vertically stable with the structure of the device. After installation, the positioning of the connecting cylinders 11 is checked to ensure that they are completely aligned with the interface of the armored vehicle and there is no looseness.

[0098] Screw drive and top force application

[0099] Operate the reversing handle 47 of the ratchet drive mechanism 4 to adjust the shift fork 44 to its initial position, so that the lead screw 3 is in the retracted state. Then, drive the annular ratchet 41 to rotate by continuously rotating or reciprocating the force bar, thereby causing the rotating drum 42 and the lead screw 3 to extend along the central axis. The extension length of the lead screw 3 can be adjusted as needed, and the top seat 6 gradually contacts the separation part of the anti-recoil device.

[0100] Top force application and disassembly

[0101] Continue operating the lever to gradually increase the force applied to the lead screw 3. The top seat 6 then begins to apply disassembly force to the anti-recoil device. Because the threaded drive of the lead screw 3 has a self-locking function, the force can be stably maintained at the target value, avoiding secondary damage caused by springback. During disassembly, observe the state of the device and the target component to ensure stable operation. Once the target component is completely separated, stop applying force and operate the reversing handle 47 to retract the lead screw 3.

[0102] Device adaptation and adjustment

[0103] If the recoil device needs to be installed or removed from another type of armored vehicle, the model of the connecting sleeve 11 needs to be changed due to the different interface size. The operator removes the original connecting sleeve 11 from the connecting seat 12, installs the new-sized connecting sleeve 11, adjusts and fixes it. The connecting seat 12 remains perpendicular to the sleeve 2, and the entire device can be adapted to the new vehicle model without major modifications.

[0104] Force control in segmented operations

[0105] For larger anti-recoil devices, the force applied by the lead screw 3 is adjusted in stages to gradually separate the target component. Precise control of the lead screw 3 is achieved through the unidirectional rotation of the ratchet drive mechanism 4, preventing damage to the device or target component from excessive force applied at once. The reversing handle 47 allows for flexible adjustment of the extension and retraction of the lead screw 3, ensuring no uncontrolled retraction occurs during operation.

[0106] Top mounting and fixing

[0107] Furthermore, this device can also be used to precisely install components. After the target component is installed in place, the lever is operated to extend the lead screw 3, causing the top seat 6 to contact the installation point of the target component. By controlling the magnitude of the jacking force, the component is slowly positioned. After the jacking force stabilizes, the target component is tightened with bolts to complete the assembly.

[0108] Post-disassembly maintenance

[0109] After completing the assembly, conduct a comprehensive inspection of the device. Clean the lubrication chamber 22, remove residual lubricant and dirt from the lead screw 3, and re-add lubricating oil to ensure smooth operation in the next operation. If there are scratches or slight deformations on the surfaces of the connector 1 and sleeve 2, they should be ground and repaired in a timely manner to ensure the overall performance of the device.

[0110] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

A fork (44) is pinned inside the retainer (43) and can rotate in the horizontal direction; the fork (44) is V-shaped, with two branches at the upper end of the V-shape being fork-shaped parts used to rotate the annular ratchet (41), and the lower end of the V-shape being the bottom; A top cone (45) is fitted at the bottom of the shift fork (44); the top cone (45) tends to move toward the annular ratchet (41), lifting the shift fork (44) and causing the shift fork (44) to swing to its limit position in a certain direction; A compression spring (46) is connected at one end to the top cone (45) and fixed at the other end, providing elastic force to the top cone (45); The reversing handle (47) fixedly connected to the shift fork (44) can overcome the elastic force of the top cone (45) under the operator's rotation operation, so that the shift fork (44) can move from one extreme position to another extreme position; The housing (48) encapsulates the cage (43) and the fork (44) and provides physical limits for the two extreme positions of the fork (44).

8. The anti-recoil top-removal device for armored vehicles as described in claim 7, characterized in that: When the fork (44) is in a certain extreme position, one fork-shaped part of the fork (44) is located between two adjacent ratchet teeth of the annular ratchet (41). At this time, rotating the retainer (43) in one direction can drive the annular ratchet (41) to rotate, while rotating in the other direction will not drive the annular ratchet (41) to move.

9. The anti-recoil top-removal device for armored vehicles as described in claim 7, characterized in that: The rotation direction of the retainer (43) is perpendicular to the central axis of the sleeve (2); the force-applying seat (5) is fixedly connected to the outer shell (48) and can be temporarily fixedly connected to the force-applying rod.

10. The anti-recoil top-removal device for armored vehicles as described in claim 1, characterized in that: The top seat (6) is a rectangular plate.
