Description

Technical Field

[0001] The utility model relates to the technical field of artillery recoil machines, in particular to an automatic recoil device for artillery recoil machines. Background Art

[0002] During routine maintenance, inspection and repair of artillery, it is necessary to check the amount of recoil mechanism fluid and the recoil mechanism rod, test the automatic latch, etc. To perform these operations, it is necessary to use the manual recoil device to pressurize the front of the recoil mechanism piston and inject the recoil fluid, so that the mechanism rod drives the gun body to move backward, thereby achieving the purpose of the manual gun body moving backward. The existing manual recoil equipment has been used for more than 20 years, and its operation procedure is complicated. Taking the manual recoil of the gun body of 250mm as an example, it is necessary to manually make a distance mark on the gun body or the rear of the breech during operation, remove the screw plug at the recoil mechanism vent, connect the special screw head, connect the injection hose, connect the injection dual-purpose pump, put the suction tube into the recoil fluid, and remove the air in the pump body. When the dual-purpose pump is activated, the liquid enters the recoil mechanism piston of the recoil mechanism, squeezes the piston to move backward, thereby driving the gun body to move backward. During operation, it is necessary to manually observe the recoil mark and stop when the gun body reaches the marked position. This operation requires the cooperation of more than 2 people, and the average completion time is about 14 minutes when all preparations are complete, which is not conducive to improving the repair efficiency. And because the recoil distance needs to be observed manually, it is easy to cause errors in the recoil mechanism fluid volume inspection calculation due to inaccurate observation of the recoil distance. Therefore, we propose an automatic recoil device for the artillery recoil mechanism to solve the above problems. Utility Model Content

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Depend on Figure 1-Figure 2 As shown, it relates to an automatic recoil device for a cannon recoil mechanism, comprising an inner tube 15 and a controller 5, the outer wall of the inner tube 15 is fixedly sleeved with an outer tube 12, the inner tube 15 and the outer tube 12 are both provided with a recoil fluid 13, the inner wall of the inner tube 15 is slidably connected with a recoil mechanism piston 11, the outer wall of the recoil mechanism piston 11 is fixedly connected with a recoil rod 14, the outer wall of the outer tube 12 is provided with a sliding hole, and the inner wall of the sliding hole is slidably connected to the outer wall of the recoil rod 14.

[0020] The inner wall of the inner tube 15 is threadedly connected with a connecting screw head 3, and the inner wall of the connecting screw head 3 is fixedly connected with a position sensor 2. The working principle of the position sensor 2 is that when an object approaches or moves away from the coil, the magnetic correlation between the object and the coil changes, thereby changing the inductance in the induction coil. By measuring the change in inductance, the position of the object can be determined, so the position change of the position ruler 9 can be detected. The position ruler 9 is slidably connected inside the connecting screw head 3, and one end of the position ruler 9 is in contact with the outer wall of the recoil machine piston 11. The outer wall of the position ruler 9 is sleeved with a spring 1, and one end of the spring 1 is pressed against the inner wall of the connecting screw head 3. Under the action of the spring 1, the position ruler 9 moves with the recoil machine piston 11.

[0021] The outer wall sliding sleeve of the position ruler 9 is provided with a bracket, the outer wall of the bracket is fixedly connected to the inner wall of the connecting screw head 3, the other end of the spring 1 is squeezed with the outer wall of the bracket, the outer wall of the connecting screw head 3 is fixedly communicated with a high-pressure hose 10, and the inner tube 15 is provided with a detection mechanism.

[0022] The detection mechanism includes an electric hydraulic pump 8, and an electromagnetic valve is installed in the pump body of the electric hydraulic pump 8. When the electric hydraulic pump 8 starts working, the high-pressure recoil fluid 13 is pressed into the front end cavity of the recoil mechanism piston 11 through the high-pressure hose 10 through the connecting screw head 3 at the recoil mechanism vent. The high-pressure recoil fluid 13 pushes the recoil mechanism piston 11 to move backward. One end of the high-pressure hose 10 is fixedly connected to the output end of the electric hydraulic pump 8. A control panel 7 is fixedly installed on the outer wall of the electric hydraulic pump 8. The outer wall of the controller 5 is electrically connected to a first cable 4. One end of the first cable 4 passes through the outer wall of the connecting screw head 3 and is electrically connected to the position sensor 2. The connection between the first cable 4 and the connecting screw head 4 is mechanically sealed. The outer wall of the control panel 7 is electrically connected to a second cable 6. One end of the second cable 6 is electrically connected to the controller 5. The control circuit of the controller can be realized by simple programming by technicians in this field.

[0023] Working principle: During the inspection, the gun body needs to be recoiled 200mm, the automatic recoil device is connected, and the 24V power supply on the gun is connected. At this time, the position scale 9 is in contact with the recoil mechanism piston 11 and is tightened under the action of the spring 1; press the zero button on the control panel 7, and the system defaults to zero recoil distance; press the number keys on the electric hydraulic pump 8 control panel 7, enter 200, and press the "Execute" key. At this time, the electric hydraulic pump 8 starts working and presses the high-pressure recoil fluid 13 into the front end cavity of the recoil mechanism piston 11 through the connecting screw head 3 at the recoil mechanism vent hole. The high-pressure recoil fluid 13 pushes the recoil mechanism piston 11 moves backward, and at the same time, the position ruler 9 moves backward with the recoil machine piston 11 under the action of the spring 1, thereby pushing the recoil rod 14 to move backward, thereby pushing the gun body to move backward. During the backward movement of the gun body, the position ruler 9 transmits the position information to the controller 5 in real time. When the recoil distance reaches 200㎜, the controller 5 issues a stop command, the electric hydraulic pump 8 stops working, and the solenoid valve in the pump body is closed to prevent the liquid injected into the front end cavity of the recoil machine piston 11 from returning, and the gun body stops at the 200㎜ recoil position; at this time, the machine rod can be inspected and maintained, and the recoil machine liquid volume can be checked. After the operation is completed, press the stop button, and the solenoid valve in the electric hydraulic pump 8 opens, and the liquid at the front end of the recoil machine piston 11 returns to the barrel of the recoil liquid 13 under the action of the internal pressure of the recoil machine. When an unexpected situation occurs during operation or an emergency shutdown is required, it can be achieved by pressing the stop button, and only one person is required to operate, saving manpower; according to the pump body flow measurement.

The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification.
