Description

Technical Field

[0001] This application belongs to the field of rocket blasting technology, specifically relating to a launch attitude locker. Background Technology

[0002] The rocket launcher of a light obstacle-clearing vehicle is typically driven by a manual or motor-driven reducer to rotate and adjust the launch angle. The launcher's position is primarily fixed by the meshing of gears within the reducer. When launching a rocket demolition device, its stable attitude and control are essential for achieving accurate obstacle clearance. Due to the significant thrust during launch, the launcher exerts a counter-thrust on the reducer. This can accelerate wear and tear on the reducer, potentially causing damage. Furthermore, wear on the reducer can make it difficult for the rocket demolition device to maintain its intended attitude, leading to deviations in positioning and strike control. Utility Model Content

[0003] In view of this, this application provides a launch attitude locker for locking the launcher when launching a rocket detonator, thereby avoiding the adverse effects of the rocket detonator launch on the decelerator and improving positioning and strike control accuracy.

[0004] This application adopts the following technical solution: A launch attitude locker, comprising: A locking plate, which is mounted on the rocket launch pad and can rotate with the rocket launch pad, the locking plate having a fan-shaped structure, and a locking tooth area provided at the arc-shaped edge of the fan-shaped structure; and... A clamping device includes a fixed plate, a pair of clamping blocks, a puller, and a driving component. The fixed plate has slots extending through both sides. The pair of clamping blocks are disposed on the fixed plate and symmetrically distributed on both sides of the slots. One end of each pair of clamping blocks forms a clamping jaw end, and the other end forms a closing end. The middle of each pair of clamping blocks is rotatably connected to the fixed plate through a rotating pin. Each closing end is movably connected to a pull rod. The end of each pull rod away from the clamping block is movably connected to the puller. The driving component is connected to the puller. A bracket is mounted on the fixed plate and connected to the puller by an elastic element that is always in a compressed state. The locking plate is disposed between the two jaws and the locking tooth area can contact the two jaws. When the two jaws are separated, the locking plate can rotate with the launcher. When the two jaws are closed, the locking tooth area is clamped, the position of the locking plate is locked, and the position of the rocket launcher is locked.

[0005] Furthermore, the jaws of the pair of clamping blocks are respectively provided with clamping teeth.

[0006] Furthermore, the locking plate is connected to a baffle plate, and a mounting base is connected to one end of the baffle plate away from the locking plate. The locking plate is mounted on the launcher via the mounting base.

[0007] Furthermore, a clamp body block is provided on the fixing plate, and a positioning key is provided on the clamp body block. The clamp block is disposed between the positioning key and the clamp body block.

[0008] Furthermore, the puller includes a connecting rod and a connector connected to one end of the connecting rod. The ends of the two pull rods away from the clamp block are movably connected to the connector. The other end of the connecting rod is sleeved in the bracket and connected to the drive member. The elastic member is connected between the connector and the bracket.

[0009] Furthermore, the elastic element is a spring, which is sleeved on the outside of the connecting rod, and its two ends are in contact with or connected to the joint and the bracket, respectively.

[0010] Furthermore, the driving component includes a rope and a power mechanism. One end of the rope is connected to the retractor, and the other end is connected to the power mechanism. The power mechanism is used to pull the retractor and the lever through the rope and compress the elastic element, or the power mechanism can cancel the power output, the elastic element can return to its initial state, and push the retractor and the lever in the opposite direction.

[0011] Furthermore, the power mechanism is one of a cylinder, an electric push rod, or a hydraulic cylinder.

[0012] The beneficial effects of this application are: The locking plate described in this application is fixedly installed on the rocket launcher and can rotate with the rocket launcher. The clamping device can clamp or release the locking plate. When the clamping device clamps the locking plate, it can fix the rocket launcher. When the rocket detonator is launched, its thrust will not directly act on the decelerator, thereby avoiding damage to the decelerator to a certain extent, thus improving the stability of the rocket launcher and improving the positioning and strike control accuracy.

[0018] Reference Figure 1-4 This application provides a launch attitude locker, comprising: A locking plate 200, mounted on the rocket launcher 100 and capable of rotating with the rocket launcher 100, the locking plate 200 having a fan-shaped structure, with a locking tooth area provided at the arc-shaped edge of the fan-shaped structure; and... A clamping device 300 includes a fixed plate 301, a pair of clamping blocks 305, a puller 302, and a driving component. The fixed plate 301 has slots 309 extending through both sides. The pair of clamping blocks 305 are disposed on the fixed plate 301 and symmetrically distributed on both sides of the slots 309. One end of each pair of clamping blocks 305 forms a clamping jaw end, and the other end forms a closing end. The middle of the pair of clamping blocks 305 is rotatably connected to the fixed plate 301 through a rotating pin 306. The closing end is movably connected to a pull rod 304. The end of the pull rod 304 away from the clamping blocks 305 is movably connected to the puller 302. The driving component is connected to the puller 302. A bracket 310 is mounted on the fixed plate 301 and is connected to the puller 302 by an elastic element 303 that is always in a compressed state. The locking plate 200 is disposed between the two jaws and the locking tooth area can contact the two jaws. When the two jaws are separated, the locking plate 200 can rotate with the launcher 100. When the two jaws are closed, the locking tooth area is clamped, the position of the locking plate 200 is locked and the position of the rocket launcher 100 is locked.

[0019] Specifically, this application applies to the field of rocket detonators, wherein the rocket detonator is mounted on a launcher 100, the launcher 100 is mounted on a breaching vehicle, and the launcher 100 can adjust its design angle by driving a reducer 500 through a manual or electric mechanism set on the breaching vehicle, thereby driving the launcher 100 to pitch and rotate. This is common knowledge in the field.

[0020] In this application, the locking plate 200 is fixedly installed on the launcher 100 and can rotate with the launcher 100. It should be noted that "fixedly installed" means that the locking plate 200 and the launcher 100 are connected by a connector and cannot move relative to the launcher 100, rather than that the locking plate 200 and the launcher 100 are not detachable.

[0021] In this application, the clamping device 300 is fixedly installed on the obstacle-clearing vehicle at the launcher 100 and is correspondingly arranged with the locking plate 200. It should be noted that "fixedly installed" means that the clamping device 300 and the launcher 100 are connected by a connector and cannot move relative to the launcher 100, rather than that the clamping device 300 and the launcher 100 are not detachable.

[0022] The working principle of this application is as follows: When the rocket detonator is launched, the launch angle of the launcher 100 needs to be adjusted first. At this time, the clamping device 300 needs to be separated from the locking plate 200. The driving component drives the retractor 302 to move, and at the same time the elastic element 303 is compressed. The retractor 302 drives the two pull rods 304 to move. The two pull rods 304 drive the two clamps 305 to rotate around the rotating pin 306. At the same time, the converging ends of the two clamps 305 move together, and the jaws of the two clamps 305 separate. At this time, the clamping device 300 separates from the locking plate 200, and the launcher 100 can be freely rotated to the appropriate launch angle position under manual or electric drive.

[0023] When it is necessary to lock the launch angle of the rocket detonator, the driving component is deactivated from the pull-back mechanism 302. The pull-back mechanism 302 then moves under the action of its elastic rebound. At the same time, the pull-back mechanism 302 drives the two pull rods 304 to move. The two pull rods 304 drive the two clamps 305 to rotate around the rotating pin 306. Meanwhile, the close ends of the two clamps 305 move away from each other, and the jaws of the two clamps 305 clamp the locking plate 200. At this time, the clamping device 300 clamps the locking plate 200, thereby locking the launch angle of the rocket launcher 100.

[0024] This application, by setting a locking plate 200 and a clamping device 300, can effectively fix the launch position of the rocket launcher 100, reduce the reverse thrust of the rocket detonator's booster force on the decelerator 500 during launch, avoid further wear on the decelerator 500, and effectively improve the launch accuracy and control accuracy of the rocket detonator. Furthermore, the locking plate 200 in this application is provided with a toothed area, which is a region along the arc-shaped edge of the locking plate 200 with a width greater than or equal to the width of the jaw segment of the clamping block 305. The toothed area is uniformly distributed with conical teeth that increase friction, thereby improving the clamping force.

[0025] It is understood that the jaws of the pair of clamping blocks 305 are respectively provided with clamping teeth.

[0026] Specifically, the clamping teeth should correspond to the locking tooth area, and their direction should be opposite to the movement direction of the locking tooth area. That is, the clamping teeth should be able to prevent the movement of the locking tooth area, thereby improving the clamping degree of the clamping device 300 on the locking plate 200.

[0027] It is understood that the locking plate 200 is connected to the baffle plate 201, and the end of the baffle plate 201 away from the locking plate 200 is connected to the mounting base 202. The locking plate 200 is mounted on the launcher 100 through the mounting base 202.

[0028] Specifically, the baffle plate 201 and the locking plate 200 can be connected by bolts. Both the baffle plate 201 and the locking plate 200 have a semi-circular groove at their connecting ends. At least one of the semi-circular grooves has a keyway on its inner wall. The output shaft of the reducer 500 passes through the circular groove formed by the two semi-circular grooves, and a key is provided on the output shaft of the reducer 500, which is inserted into the keyway. The mounting base 202 and the launcher 100 can be connected by bolts. As described above, the locking plate 200 is directly connected to the launcher 100 and connected to the output shaft of the reducer 500 via a keyway.

[0029] It is understood that the clamp body block 307 is provided on the fixing plate 301, the clamp body block 307 is provided with a positioning key 308, and the clamp block 305 is disposed between the positioning key 308 and the clamp body block.

[0030] Specifically, the clamp body block 307 is a plate-shaped structure and can be bolted to the fixing plate 301. The clamp body block 307 and the positioning key 308 can be an integral structure to support the clamp block 305. The positioning key 308 is a plate-shaped structure, and the positioning key 308 and the clamp body block 307 restrict the movement of the clamp block 305 within a certain range by vertically restricting it. This ensures that the clamp block 305 will not sway towards the sides of the fixing plate 301 during clamping or loosening, resulting in a more stable clamping structure.

[0031] It is understood that the puller 302 includes a connecting rod and a connector connected to one end of the connecting rod. The ends of the two pull rods 304 away from the clamp block 305 are movably connected to the connector. The other end of the connecting rod is sleeved in the bracket 310 and connected to the drive member. The elastic member 303 is connected between the connector and the bracket 310.

[0032] Specifically, the aforementioned bracket 310 can be an inverted L-shaped structure, with one end of the connecting rod passing through the short axis of the bracket 310 and able to move freely within the bracket 310. The puller 302 adopts a structure in which a connecting rod is sleeved within the bracket 310. During the process of the connecting rod being pulled by the driving component, the connecting rod will always move along the long axis of the bracket 310, playing a good guiding role and ensuring that the pair of clamps 305 can be stably clamped and released.

[0033] It is understood that the elastic element 303 is a spring, which is sleeved on the outside of the connecting rod, and its two ends are in contact with or connected to the joint and the bracket 310 respectively.

[0034] Specifically, the elastic element 303 is a spring and sleeved on the outside of the connecting rod. Its installation is relatively stable, and the elastic force tends to be relatively stable when contracted (in a straight direction), which is more conducive to the opening and closing clamping and releasing operation of a pair of clamps 305.

[0035] It is understood that the driving component includes a rope and a power mechanism. One end of the rope is connected to the puller 302, and the other end is connected to the power mechanism. The power mechanism is used to pull the puller 302 and the pull rod 304 through the rope and compress the elastic element 303, or the power mechanism can cancel the power output, the elastic element 303 can return to its initial state, and push the puller 302 and the pull rod 304 in the opposite direction.

[0036] Specifically, the driving component is a combination of a rope and a power mechanism. In use, the power mechanism can pull the rope to open (release) a pair of clamps 305, or remove the power and use the elastic element 303 to clamp the pair of clamps. The overall structure is simple in design and the power output is stable. The rope is preferably made of steel wire rope, and a rope loop can be designed at the end of the connecting rod, and the rope can be tied to the rope loop.

[0037] It is understood that the power mechanism can be any one of the existing technologies, such as a pneumatic cylinder, an electric push rod, or a hydraulic cylinder, and can be connected to a controller to achieve automated control operation.

[0038] The above embodiments are merely preferred technical solutions of this application and should not be considered as limitations on this application. The embodiments and features described therein can be arbitrarily combined without conflict. The scope of protection of this application should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of this application.
