Abstract
Description
Technical Field
[0001] The present invention relates to the field of radar locking technology, and in particular to a high-rigidity locking device for radar equipment. Background Art
[0002] When a radar is transported long distances by road or rail, the antenna is either lifted vertically by a lifting mechanism, lifted horizontally by a four-bar linkage, or flipped around a fixed fulcrum by a lifting mechanism, ultimately transitioning from the transport and storage state to the operational state. Vertical lift is generally used for pure height lifting in situations where horizontal space is limited. The latter two lifting mechanisms require a certain amount of horizontal and vertical space. With the advancement of radar technology, the requirements for tracking accuracy and dynamic response capabilities are becoming increasingly higher. Regardless of the lifting situation, high structural rigidity is required after the lift is in place. Therefore, a locking mechanism is used to lock the antenna base after the lift is in place to ensure tracking accuracy during dynamic tracking of targets.
[0003] Currently, radar antennas are locked primarily through methods such as buckles and pinholes. Buckle locking typically involves multiple locking mechanisms distributed on a single plane. To avoid internal stress when locking simultaneously, the edge blocks themselves must possess a certain degree of flexibility and high machining and assembly precision are required. Furthermore, external forces can cause locking failure. Pinhole locking is the most common locking method, employing single or multiple groups of tapered or cylindrical pins. This requires high machining precision and good alignment between the pins and holes, while also requiring high structural rigidity. After long-term operation, if the base of the pin or hole is deformed by force, the alignment deteriorates, and the pin or hole experiences backlog deformation, generating significant friction. High friction makes unlocking difficult or even impossible, especially when the friction is high.

[0022] The above and other technical features and advantages of the present invention are described in more detail below with reference to the accompanying drawings.
[0023] like Figures 1 to 4 As shown, Figure 1 A structural view of a high-rigidity locking device equipped for the radar; Figure 2 A top view of the structure of a high-rigidity locking device equipped for the radar; Figure 3 is a schematic diagram of the cooperation between the latch plate and the latch mechanism; Figure 4 Schematic diagram of the installation of the high-rigidity locking device equipped with the radar.
[0024] The high-rigidity locking device of the radar equipment described in the present invention includes a base 1, a lifting mechanism 2, a latch plate 3, a flange seat 4, a transition connecting plate 5, a cabin carrier 6 and a latch mechanism 7; the lifting mechanism 2 is arranged in the cabin carrier 6, the base 1 is arranged on the lifting mechanism 2, and the lifting mechanism 2 drives the base 1 to adjust the height; the transition mounting plate is fixedly arranged at the top end of the lifting mechanism 2 through the flange seat 4, and the transition mounting plate is fixedly arranged on the rigid frame of the cabin carrier 6, the latch plate 3 is fixedly arranged on the transition mounting plate, and the latch mechanism 7 is fixedly arranged on the base 1, and the latch mechanism 7 and the latch plate 3 are arranged in a one-to-one correspondence.
[0025] When the lifting mechanism 2 lifts the base 1 to the working position, the base 1 is rigidly connected to the cabin carrier 6 through the engagement and fixing between the latch mechanism 7 and the latch plate 3 .
[0026] Preferably, the lifting mechanism 2 is provided with a plurality of lifting rods, and the top ends of the lifting rods are fixedly provided with the transition connecting plates 5 through the flange seats 4 .
[0027] like Figure 5 、 Figure 6 As shown, Figure 5 is a structural sectional view of the latch mechanism; Figure 6 The figure is a view of the connection structure of the latch mechanism. The latch mechanism 7 includes an electric push cylinder 71, a latch 72 and a latch seat 73. The latch seat 73 is fixedly arranged on the base 1, and the latch 72 is arranged in an adjustment hole in the latch seat 73. The electric push cylinder 71 is fixedly arranged on the latch seat 73, and the telescopic rod of the electric push cylinder 71 is fixedly connected to the latch 72, thereby driving the latch 72 to move axially in the adjustment hole. The electric push cylinder 71 pushes the latch 72 outward, so that the end of the latch 72 is fixedly engaged with the latch plate 3, thereby achieving a mating engagement between the latch mechanism 7 and the latch plate 3.
[0028] Preferably, the adjustment hole is set as a cylindrical hole, and the pin 72 includes a guide section and a clamping section. The guide section is set to be cylindrical, and the diameter of the guide section is consistent with the diameter of the adjustment hole. The end of the guide section is fixedly connected to the telescopic rod of the electric push cylinder 71 to ensure that the pin 72 moves stably in the adjustment hole.
[0029] A first inclined end surface is provided on the snap-fit section, and a first inclined end surface is provided on the latch 72 plate 3. The first inclined end surface and the first inclined end surface are provided correspondingly and have the same inclination angle, thereby ensuring that when the latch mechanism 7 and the latch 72 plate 3 are in contact, the first inclined end surface and the first inclined end surface are snap-fitted and fitted to achieve mating fixation.
[0030] Preferably, an anti-rotation pin 74 is provided at the connection position between the end of the guide section and the telescopic rod of the electric push cylinder 71 to prevent the first inclined end surface from rotating.
[0031] Similarly, the cross section of the adjustment hole can be set to a square shape, and the latch pin 72 can also be set to a corresponding square cross section. In the case where the cross section of the adjustment hole is set to a square shape, the anti-rotation pin 74 may not be provided.
[0032] Preferably, the latch mechanism 7 is also provided with a first travel switch 75 and a second travel switch 76, and the first travel switch 75 and the second travel switch 76 are both provided on the electric push cylinder 71. The first travel switch 75 and the second travel switch 76 correspond to the locking position and the unlocking position of the latch 72 respectively, so that there is a signal display status when the latch 72 is inserted and pulled out.
[0033] The plurality of latch mechanisms 7 are all arranged on the same horizontal plane and are radially symmetrically arranged along the rotation center of the base 1. The axial extension lines of the latches 72 intersect at the intersection of the horizontal plane where the axis of the latch 72 is located and the axis of the rotation center.
[0034] After lifting into place, there is a small gap between the flange surface of the base 1 and the lower surface of the transition connecting plate 5, the size of the gap being the transmission clearance of the lifting mechanism 2. After the latch 72 is locked, the gap between the flange surface of the base 1 and the lower surface of the transition connecting plate 5 is zero.
[0035] The high-rigidity locking device for radar equipment described in the present invention includes a latch mechanism 7, a latch plate 72, a base 1, a lifting mechanism 2, a flange seat 4, a transition plate 5, and a shelter carrier 6. The base 1 is fixedly connected to the nut of the lifting mechanism 2, which is in turn fixedly connected to the shelter carrier 6. The latch mechanism 7 is fixed to the base 1, the latch plate 72 is fixed to the upper horizontal surface of the transition plate 5, the two vertical surfaces of which are fixedly connected to the shelter carrier 6, and the lower horizontal surface of the transition plate 5 is connected to the top of the lifting mechanism 2 via the flange seat 4.
[0036] The latch mechanism 7 is composed of an electric push cylinder 71, a latch 72, a latch seat 73, an anti-rotation pin 74, a travel switch, etc. The latch seat 73 is fixed to the base 1, and the interior of the latch seat 73 is provided with a through hole. The latch 72 is connected to the push rod of the electric push cylinder 71, and the latch 72 is sleeved with the inner hole of the latch seat 73.
[0037] The latch 72 is an integrally formed structure, comprising a cylindrical portion and an inclined portion. The cylindrical portion fits within the internal through-hole of the latch seat 73, forming a transition or clearance fit. One end face of the cylindrical portion is connected to the push rod of the electric push cylinder 71. When the electric push cylinder 71 pushes the electric rod, it simultaneously pushes the latch 72, and the anti-rotation pin 74 connects and prevents the latch 72 from rotating. The inclined portion abuts the inclined surface of the latch plate 3 after the electric push cylinder 71 is fully extended. The inclined surface at the rear of the latch 72 and the inclined surface of the latch plate 3 are the same inclination, forming a contact fit.
[0038] A travel switch indicates the status of both the insertion and removal of the latch 72. The travel switch is fixed to the cylinder body of the electric cylinder. To ensure that the inclined surface of the latch 72 is completely aligned with the inclined surface of the latch plate 3 after the latch 72 is extended, the actual stroke of the electric cylinder is slightly larger than the designed stroke. After the latch 72 is fully extended, a travel trigger signal is output, causing the latch 72 to continue its movement. The delay time ensures that the latch 72 is extended to the designed position.
[0039] The above description is merely a preferred embodiment of the present invention and is intended to be illustrative rather than restrictive of the present invention. Those skilled in the art will appreciate that many changes, modifications, and even equivalents may be made to the present invention within the spirit and scope of the claims, all of which fall within the scope of protection of the present invention.
