Description

Sliding limiting device for ship-borne tracking turret

Technical Field

The utility model relates to the technical field of ship-based tracking turret control, in particular to a sliding limiting device for a ship-based tracking turret.

Background

In ship-borne tracking equipment, a turret is generally used for bearing the tracking equipment to rotate within a certain rotation angle range. In order to meet the continuous and reciprocating tracking requirement of the turret on the target, it is sometimes required that the rotation angle of the turret reaches a limit rotation angle position, even exceeds a limit rotation angle position of a certain angle, such as reaching + -185 degrees. For such turrets requiring a certain angular range, a limiting device is required to limit the rotation angle of the turret within the required range. The existing limiting device mainly comprises a mechanical type limiting device and an electrical type limiting device or a combination of the mechanical type limiting device and the electrical type limiting device. The defects are that: the electrical or combined limiting device has relatively complex structure, and the limiting function can be realized only by combining the related electrical switch and the mechanical device, so that the cost is high. Although the mechanical stop device is relatively low in cost, the stop block itself in the conventional mechanical stop device occupies a certain physical space, so that the rotation angle of the shaft is less than ±180°. In view of the limited internal space of the ship-based tracking turret, the size of the limiting mechanism is not easy to be too large. In the existing improved limiting device capable of achieving the requirement, most of the limiting devices are relatively complex in structure and large in size, or can only achieve +/-180 degrees, but cannot meet the requirement of limiting corner positions exceeding a certain angle.

Detailed Description

The present utility model will be further described in detail below with reference to specific embodiments and with reference to the accompanying drawings, in order to make the objects, technical solutions and advantages of the present utility model more apparent.

As shown in fig. 1, 2 and 3, the present utility model provides a sliding limiting device for a ship-borne tracking turret. The limiting device comprises a bottom plate 1, a collision block 2, a stop block 3, a sliding block 4 and two elastic limiting pieces 5.

As shown in fig. 1 and 2, a guide rail is provided at the middle of the base plate 1 to allow the slider 4 to be inserted into the rail, and a stopper 3 is fixed to the slider 4 to extend in a direction perpendicular to the guide rail. Two elastic limiting pieces 5 are respectively arranged at two ends of the rail.

The sliding block 4 can slide on the bottom plate 1 along the guide rail for a certain distance, and the guide rail and the sliding block 4 are arranged in a simpler rectangular shape so as to be convenient for processing and manufacturing.

The base plate 1 is provided with associated holes so that the stop device can fix the elastic stop 4 and in place in the turret casing.

As shown in fig. 1 and 2, the stop block 3 and the slide block 4 are connected together through screws, and the slide block 4 can keep the device stable under the action of the elastic limiting pieces 5 at two sides under the condition that the collision block 2 does not collide with the stop block 3, so that the safety and reliability of the device are improved.

As shown in fig. 3, the elastic stopper 5 includes a housing 501, a front cover 502, a connecting rod 503, a spacer 504, a spring 505, and a fixing block 506.

Wherein shim 504 is embedded on connecting rod 503, shim 504 will contact with the slider, and shim 504 is made of a nonmetallic material with certain elasticity to avoid hard contact of connecting rod 503 with slider 4; one end of the spring 505 is sleeved on the fixed block 506, the other end of the spring 505 is abutted against the connecting rod 503, and the spring 505 is respectively contacted with the connecting rod 503 and the fixed block 506 and is in an uncompressed state. The elastic limiting piece 5 can enable the sliding block 4 to maintain a stable state under the action of certain external force under the action of the springs 505 at the two sides. The housing 501 and the front cover 502 enclose the spring 505 inside the elastic stopper 5.

As shown in fig. 1, when the rotation angle of the bump 2 is 0 °, the bump 2 and the limiting device are respectively located at two sides of the shaft, and the bump 2 and the stop 3 are on the same axis.

In this example, as shown in fig. 4 and 5, when the bump 2 is driven by the shaft to rotate from 0 ° to around 180 °, the bump will collide with the stop block 3, and when the bump 2 continues to move, the stop block 3 and the fixed slider 4 move along the guide rail on the base plate 1. At this time, slider 4 pushes connecting rod 503 to move through spacer 504. At the same time, connecting rod 503 begins to compress spring 505. Continued rotation of ram 2 causes connecting rod 503 to continue to move compression spring 505 until connecting rod 503 hits fixed block 506, at which point rotation is stopped, thereby achieving a limit function.

As shown in fig. 1, 3, 4 and 5, the rotation angle of the stopper exceeds 180 ° by an angle θ, which is the distance L between the connecting rod 503 and the fixed block 506 of the elastic stopper 4 ₁ Width L of front end of stopper 3 ₂ Width L of striker 2 ₃ And the distance L from the center of the rotating shaft to the front end of the collision block ₄ And (5) correlation. Calculated from the associated mathematical relationship, the relationship between them The rotation angle range of the striker 2 from the 0 ° position is- (180 ° +θ) to + (180 ° +θ).
