Description

Technical Field

[0001] This utility model relates to the field of installation tooling technology, specifically to a leveling device for installing a radar antenna. Background Technology

[0002] A radar panel is composed of several antenna boards, and the planar precision of the radar panel requires high assembly accuracy.

[0003] During the assembly process, the product frame is usually first installed on the antenna fixture. Then, dial indicators are set at each installation point of the product frame to monitor the installation angle of the antenna board at that position. The antenna board is then adjusted based on the information fed back by the dial indicators. Although this method has high precision, it is relatively cumbersome to operate and requires continuous monitoring of the dial indicator readings, which is not conducive to improving production efficiency. A more convenient and faster leveling device is needed to adjust the antenna board to achieve the ideal flatness. Therefore, a leveling device for radar antenna installation is proposed. Utility Model Content

[0004] In order to solve the technical problems existing in the prior art, the present invention provides a leveling device for radar antenna installation.

[0005] To solve the above technical problems, the present invention provides the following technical solution: a leveling device for installing a radar antenna, comprising a supporting beam, wherein both ends of the supporting beam are connected to a set of downwardly extending telescopic cantilever arms, and the lower ends of the two sets of telescopic cantilever arms are fixed with an I-beam frame, the two sets of I-beam frames are symmetrically arranged, and a gap is formed between the two symmetrically arranged I-beam frames for the antenna board to be installed.

[0006] One set of I-beams has threaded holes at each of its four corners, and an adjuster is installed in each of the threaded holes. Another set of I-beams has through holes at each of its four corners, and a limiter is installed in each of the through holes. The positions of the four sets of adjusters and the four sets of limiters correspond one-to-one.

[0007] Preferably, the load-bearing beam includes a base beam, a sliding shaft, and a first spring. Two sets of base beams are provided, and the two sets of base beams are arranged symmetrically. The sliding shaft passes through one set of base beams, and one end of the sliding shaft is connected to the side of the other set of base beams. The first spring is sleeved on the outside of the other end of the sliding shaft, and the two ends of the first spring abut against the outer wall of one set of base beams and the end of the sliding shaft, respectively.

[0008] Preferably, the foundation beam is a continuous stepped shape, and a snap-fit ​​area for snap-fit ​​is formed below the two sets of foundation beams. The length of the sliding shaft is longer than the length of the top part of the foundation beam, and a space for the foundation beam to move is formed outside the sliding shaft.

[0009] Preferably, the adjuster includes a screw and a contact head. The screw is installed in the threaded holes at the four corners of the I-beam frame by means of a threaded connection, and the contact head is installed at the end of the screw near the limiter.

[0010] Preferably, the contact head is spherical and made of a flexible material.

[0011] Preferably, the limiter includes a guide shaft and a suction cup. The guide shaft slides horizontally through the four corners of the I-beam. A suction cup for attaching the antenna board is installed at one end of the guide shaft near the adjuster.

[0012] Preferably, the limiter includes a limit block, a second spring, and a groove. A receiving cavity is formed in the end of the I-beam frame, and the receiving cavity communicates with the through hole where the guide shaft is located.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model is equipped with four sets of adjusters and four sets of corresponding limiters. The four sets of adjusters and four sets of corresponding limiters are used to adjust the four corners of the antenna board. The adjusters push the antenna board and drive the guide shaft of the limiter to move until the limit block is locked into the groove under the action of the spring, thus determining the position of the antenna board.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments, highlighting the above and other technical features and advantages of the present invention. However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive.

[0028] Example:

[0029] like Figure 1 - Figure 6 As shown, this utility model provides a leveling device for installing a radar antenna, including a supporting beam 1. Both ends of the supporting beam 1 are connected to a set of downwardly extending telescopic cantilever arms 2. The lower ends of the two sets of telescopic cantilever arms 2 are fixed with an I-beam 3. The two sets of I-beams 3 are symmetrically arranged, and a gap is formed between the two sets of I-beams 3 for the antenna board to be installed.

[0030] The load-bearing beam 1 includes a foundation beam 11, a sliding shaft 12, and a first spring 13;

[0031] Two sets of foundation beams 11 are provided, symmetrically arranged, with adjacent surfaces of the two sets of foundation beams 11 fitting together to form a slot for engaging with the top beam of the antenna fixture. A sliding shaft 12 passes through one set of foundation beams 11, with one end of the sliding shaft 12 connected to the side of the other set of foundation beams 11. A first spring 13 is sleeved on the outside of the other end of the sliding shaft 12, with both ends of the first spring 13 abutting against the outer wall of one set of foundation beams 11 and the end of the sliding shaft 12, respectively. The length of the sliding shaft 12 is longer than the length of the top part of the foundation beam 11, and a space is formed outside the sliding shaft 12 for the foundation beams 11 to move. Under the elastic force of the first spring 13, the two sets of foundation beams 11 tend to move closer to each other, so that the supporting beam 1 can be clamped on the top beam of the antenna fixture.

[0032] One set of I-beams 3 has threaded holes at each of its four corners, and an adjuster 4 is installed in each set of threaded holes. Another set of I-beams 3 has through holes at each of its four corners, and a limiter 5 is installed in each set of through holes. The positions of the four sets of adjusters 4 and the four sets of limiters 5 correspond one-to-one. The adjuster 4 can move linearly along the direction of the limiter 5 to push the antenna board to press the limiter 5 until the limiter 5 is activated, so that the position of the antenna board can no longer be changed. Since the limiters 5 have the same structure, the positions of the four corners of the antenna board can be kept consistent, and there is no need to adjust the readings using a dial indicator, thereby effectively improving the leveling efficiency.

[0033] The regulator 4 includes a screw 41 and a contact head 42;

[0034] The screw 41 is installed in the threaded holes at the four corners of the I-beam 3 by means of threaded connection. The contact head 42 is installed at the end of the screw 41 near the limiter 5. The contact head 42 is spherical and made of flexible material. The contact head 42 made of flexible material can avoid pressure damage to the antenna board.

[0035] The limiter 5 includes a guide shaft 51 and a suction cup 56;

[0036] The guide shaft 51 slides horizontally through the four corners of the I-beam 3. A suction cup 56 for attaching the antenna board is installed at the end of the guide shaft 51 near the adjuster 4. The suction cup 56 is used to attach the antenna board to prevent the guide shaft 51 from sliding between itself and the antenna board during movement, thus avoiding damage to the antenna board.

[0037] The limiter 5 includes a limit block 52, a second spring 53, and a groove 54;

[0038] An accommodating cavity is provided at the end of the I-beam 3, which is connected to the through hole of the guide shaft 51. The limiting block 52 and the second spring 53 are vertically arranged in sequence in the accommodating cavity. The two ends of the second spring 53 abut against the accommodating cavity and the end of the limiting block 52, respectively. Several sets of grooves 54 are provided, and several sets of grooves 54 are sequentially opened on the upper part of the guide shaft 51. The guide shaft 51 cooperates with the limiting block 52 and the second spring 53 through the grooves 54 to form a locking and limiting structure. The grooves 54 are opened on the guide shaft 51 at one end near the position of the adjuster 4. When the adjuster 4 pushes the antenna board to squeeze the limiter 5, the limiter 5 can form a self-locking mechanism.

[0039] The side of the groove 54 away from the regulator 4 is an arc-shaped slope, and the limiting block 52 has an inclined surface that adapts to the slope of the groove 54. In this way, after the guide shaft 51 self-locks, it can push the limiting block 52 back into the receiving cavity by moving in the opposite direction, thereby releasing the self-locking state.

[0040] The guide shaft 51 has a protruding rib 55 arranged along its axial direction on its outer side, and the end of the I-beam 3 where it is located has a sliding groove that can be adapted to the protruding rib 55 to ensure that the guide shaft 51 can only perform linear movement.

[0041] In this embodiment, before the leveling operation, the two base beams 11 of the supporting beam 1 are first pulled apart to increase the width of the slot. Then, it is placed on the top beam of the antenna fixture. The first spring 13 is used to bring the two base beams 11 together to ensure that the supporting beam 1 can be firmly clamped. Then, the antenna board is placed in the gap between the two I-beams 3 and the suction cup 56 is attached to the antenna board. Then, the screw 41 of the adjuster 4 is rotated to make the contact head 42 abut against the antenna board and push it. During this process, the guide shaft 51 of the limiter 5 moves accordingly. The limit block 52, which was originally abutting against the shaft of the guide shaft 51, falls into the groove 54 as the guide shaft 51 moves to form a self-locking mechanism. At this time, the position of the antenna board no longer changes and can be fixed. Since the limiters 5 at the four corners have the same structure, the position of the four corners of the antenna board can be kept consistent. After the antenna board in the horizontal direction is leveled, the height can be adjusted by the telescopic cantilever 2 to carry out the next round of leveling operation for the antenna board at a higher position.

[0042] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
