A locking device is provided between the frame 5 and the carrying platform 4, which can lock the carrying platform 4 when the self-locking of the worm 2 and the worm wheel 3 fails due to wear, so as to avoid the free swing of the high and low machine components and affect the shooting accuracy. In this technical solution, the control of the pitch angle of the bearing platform 4 is realized, and it has good self-locking performance.

As shown in Figure 2, one implementation of the locking device in the above technical solution is to install a ratchet mechanism on the left and right trunnions 6, 7 respectively, and the ratchet mechanism includes ratchets 8, 9 and pawls 10, 11, two Two ratchets 8,9 are fixedly connected with the left and right trunnions 6,7 respectively, and the installation direction of the ratchet mechanism installed on the left trunnion 6 is opposite to that of the ratchet mechanism installed on the right trunnion 7, so that the two ratchet mechanisms are limited respectively Limit the rotation of the carrying platform 4 in two directions. Through the limitation of these two ratchet mechanisms, the carrying platform 4 is locked in a fixed position. Even when the self-locking of the worm gear and worm transmission system fails, the carrying platform 4 will not rotate by itself, ensuring the shooting accuracy of the remote control weapon station . When the bearing platform 4 needs to be rotated to adjust the pitch angle, the ratchets 10, 11 are lifted from the ratchet wheels 8, 9 to remove the restrictions on the movement of the ratchet wheels 8, 9, so that the bearing platform 4 can adjust the pitch angle under the drive of the transmission system .
