Description

{Barrel Droop Prevention Apparatus of High Angle Weapon}

The present invention is intended to solve the problem of sagging due to the weight of barrel when heat is radiated manually due to a motor failure for square control of the barrel.

In the automatic operation system of the tattoo machine, if the automatic operation can not be performed due to a failure of the drive motor and the drive control device, it is necessary to enable the heat radiation of the tattoo machine manually.

As a representative example of a gun firearm, if you look at the manual operation system of a mortar, the operator sets the barrel to the target and secures the range by controlling the gun barrel.

In recent years, the mortar has been able to automatically control the turning angle and squareness of the gun barrel by driving the motor, making it possible to move the vehicle and making the mortar itself smaller. When the height of the jigger is lowered, the center of gravity of the actuator for controlling the square of the barrel and the barrel may not coincide with the rotation axis of the barrel in miniaturizing the jig that adjusts the square.

In order to dissipate the attractor quickly during manual operation, the center of gravity of the driving load must be balanced with the center of gravity to balance the center of gravity. However, if the gravity center deviates from the axis of rotation by lowering the height, Even if the barrel is heated to a desired angle due to a central imbalance, the barrel is sagged downward due to the weight of the barrel and the actuator.

In addition, since the height of the firearm is low, the height of the operator's key height and the position of the handle for manual driving do not match at the time of manual operation, thereby causing difficulties in manual operation.

Fig.

As shown in FIG. 1, the automatic launcher 100 is hinged to the lower end of the barrel 101 on a rotating base plate 110 mounted on a vehicle or the like, and the actuator 120 is hinged to the base plate 110 And the barrel 101 while controlling the angle of the barrel 101 while expanding and contracting. The actuator 120 is expanded and contracted by receiving the power of the motor 103 mounted on the base plate 110 so as to control the square of the barrel 101 through the control of the motor 103.

On the other hand, the automatic fire extinguisher (100) must be able to heat manually even in an emergency state where the automatic operation is not performed.

In order to solve the problem of sagging due to the self weight of barrel during manual operation as described in the prior art, in the present invention, the expansion and contraction control of the actuator 120 is controlled through the worm gear box 130 have. Therefore, the mechanical properties of the worm gear 131 and the worm wheel 132 prevent the barrel 101 from sagging downward.

Hereinafter, a barrel deflection preventing device of the thus configured projecting machine will be described in detail.

2 to 5, the front end of the expandable actuator 120 is hinged to the bottom surface of the barrel 101 and the rear end of the actuator 120 is connected to the worm gear box 130 .

4, the worm gear box 130 includes a worm gear 131 rotated by the input shaft 141 and a worm wheel 132 rotated in engagement with the worm gear 131, .

Here, the axis of the worm wheel 132 is connected to the screw shaft 121 located inside the actuator 120 shown in Fig. The worm gear 131 that cooperates with the input shaft 141 rotates the worm wheel 132 and the screw shaft 121 rotates by the rotation of the worm wheel 132 to control the expansion and contraction of the actuator 120.

The rotation of the worm wheel 132 is restricted due to the mechanical characteristics of the worm gear 131 and the worm wheel 132 even though the actuator 120 receives a force in a direction in which the actuator 120 is expanded or contracted by the weight of the barrel 101 during manual operation It is possible to prevent deflation of the barrel 101.

At this time, the worm wheel 132 rotates along the outer circumferential surface of the worm gear 131, so that the inclination of the actuator 120 is also equal to the square of the barrel 101 .

The operator manually rotates the handle 151 of the manual control unit 140 mounted on the upper surface of the base plate 110 to change the slope of the barrel 101, that is, the slope of the actuator 120.

The manual control unit 140 is mounted to be adjustable in height in accordance with the height of the operator. The elevation adjustment will be described later in detail, and the expansion and contraction control relationship of the actuator 120 will be described below.

The manual control unit 140 is equipped with a handle 151 for rotating the horizontal axis 151S and a first bevel gear box 161 mounted on the horizontal axis 151S to transmit the power of the horizontal axis 151S to the universal joint 170 .

A second bevel gear box 162 is mounted on the lower end of the universal joint 170 to transmit the power of the universal joint 170 to the input shaft 141 connected to the shaft 131S of the worm gear 131. In this case, the shaft of the motor 103 is connected to the second bevel gear box 162 so that the actuator 120 is operated by the power of the motor 103 during automatic operation, and when the motor 103 is manually operated Is controlled by the rotation of the handle 151. As shown in FIG. 2, a coupling 180 is mounted on the input shaft 141 to transmit power and facilitate disassembly and assembly during maintenance.

Therefore, when manual operation is required due to a failure of the motor 103, the handle 151 of the manual control unit 140 is rotated to rotate the horizontal axis 151S, the first bevel gear box 161, the universal joint 170, The worm gear 131 rotates through the gear box 162 and the input shaft 141 so that the worm wheel 132 rotates and the screw shaft 121 of the actuator 120 rotates so that the square of the barrel 101 Respectively.

The principle of controlling the angle of the barrel 101 by the rotation of the screw shaft 121 is that the upper end of the nut shaft 123 fastened to the screw shaft 121 is mounted on the barrel 101, Is moved in the longitudinal direction of the nut shaft 123 while rotating. That is, when the screw shaft 121 is inserted into the nut shaft 123, the length of the actuator 120 is contracted. On the other hand, when the screw shaft 121 comes out of the nut shaft 123, Lt; / RTI > As the actuator 120 is expanded and contracted, the slope of the barrel 101 hinged to the base plate 110 is changed and the angle of the square is controlled.

On the other hand, during the automatic operation, the manual control unit 140 is lowered on the upper surface of the base plate 110, but is elevated to be adjusted to the operator's key in the manual operation.

To this end, a stretchable gas shock absorber 190 is mounted between the manual control unit 140 and the base plate 110. Accordingly, during the manual operation, the gas shock absorber 190 is stretched to move the manual control unit 140 upward.

Therefore, as shown in Fig. 7, the stem 171 of the universal joint 170 is retractably mounted. Specifically, a piston 173 is inserted into the cylinder 175, and a key 177 is formed around the piston 173, and a keyway is formed on the inner circumferential surface of the cylinder 175. The rotational force transmitted through the first bevel gear box 161 transmits the rotational force to the second bevel gear box 162 by the stem 171 matched with the key 177 and the key groove, The piston 173 moves in the longitudinal direction of the cylinder 175. In this case,

As described above, according to the present invention, when the shooter 100 is operated manually, deflation phenomenon can be prevented by the self weight of the gun 101 through the worm gear box 130, thereby improving the accuracy of the shooter And also allows the operator to easily control the attractor 100 during manual operation, thereby facilitating heat dissipation of the attractor 100.
