Description

Technical Field

[0001] The utility model belongs to the technical field of antenna supporting equipment, and in particular relates to a steel wire rope supporting mechanism for a radar antenna. Background Art

[0002] The parabolic curved antenna is hundreds of meters long and tens of meters in diameter. During use, in order to better perform astronomical observations, radar searches, and other tasks, the curved antenna needs to have a certain angle adjustment capability so as to better receive signals.

[0003] In the prior art, there is a curved connecting plate connected to the hinge shaft at the bottom of the support plate of the curved antenna. The two ends of the curved connecting plate are respectively connected to the ends of the wire rope. The middle section of the wire rope extends backward to the reel and is wound on the reel. The wire ropes on the adjacent curved connecting plates are driven by the same reel. When the reel rotates, the wire rope at one end of the curved connecting plate becomes longer and the wire rope at the other end becomes shorter. The length of the wire rope at both ends of the curved connecting plate is changed so that the wire rope pulls the curved connecting plate. The curved connecting plate drives the curved antenna to rotate along the hinge shaft to adjust the angle of the curved antenna. The rotating mechanism has a simple structure, high angle adjustment accuracy, and is easy to use. However, during use, since the wire rope is suspended in the air for a long time without a supporting mechanism and is exposed to the air, dust and impurities are easily accumulated on the wire rope, and even rust occurs. Regular maintenance is required by the staff, otherwise it may affect the pulling effect of the wire rope on the curved antenna, and the curved antenna cannot be adjusted normally. Utility Model Content

[0004] In order to solve the problems existing in the above-mentioned prior art, the utility model provides a radar antenna wire rope support mechanism, which can provide support for the suspended wire rope and automatically apply rust inhibitor to the wire rope during the process of adjusting the angle of the curved antenna, thereby reducing the frequency of manual maintenance and extending the service life of the wire rope.

[0005] The specific technical solution adopted by the utility model is:

[0006] The radar antenna wire rope support mechanism includes a mounting frame, and the key point is that the mounting frame is provided with a support assembly and an oil brush assembly matched with the wire rope, the support assembly includes a support conveyor belt located below the wire rope and arranged in close contact with the wire rope, and a first roller matched with the support conveyor belt, the oil brush assembly includes a rolling brush and a rust inhibitor supply box matched with the rolling brush, and the rolling brush is transmission-connected to the first roller and rotates with the drive of the first roller.

[0007] The rolling brushes are arranged in pairs and adjacent to each other, the bristles of the rolling brushes are in contact with the surface of the wire rope, the bristles at the adjacent ends of the two rolling brushes are arranged crosswise, and the rust inhibitor supply box is located below the rolling brushes and matched with the bristles.

[0008] The rolling brush is an oil brushing conveyor belt installed with the aid of a second roller, and the bristles are arranged on the outer surface of the oil brushing conveyor belt.

[0009] The adjacently arranged rolling brushes rotate in the same direction respectively by the driving of the first roller.

[0010] The rust-proof agent supply box is provided with a dust cover, and the dust cover is provided with an opening matched with the bristles.

[0011] The mounting frame is also provided with a tensioning wheel matched with the steel wire rope.

[0012] The beneficial effects of the utility model are:

[0013] The utility model adopts a supporting component to partially support the suspended steel wire rope, and an oil brushing component to brush the steel wire rope with a rust preventive agent, and cleans the steel wire rope at the same time; when the angle of the arc antenna needs to be adjusted, the reel rotates, and the length of the steel wire rope from the two ends of the arc connecting plate to the reel is respectively retracted and released. During the retraction and release process, the steel wire rope moves, and friction is generated with the supporting conveyor belt, driving the supporting conveyor belt to rotate, thereby causing the first roller to rotate, and the first roller drives the rolling brush to rotate. During the rotation of the rolling brush, the rust preventive agent is dipped through a rust preventive agent supply box, and the rust preventive agent is continuously rotated to brush the steel wire rope, and at the same time, impurities such as dust attached to the steel wire rope can be brushed off, so as to prevent the steel wire rope from being corroded or rusted, thereby increasing the service life of the steel wire rope and ensuring that the steel wire rope can work normally; with the retraction and release of the steel wire rope as the source of driving force for the rolling brush, no additional power supply is required, and the frequency of manual maintenance is reduced.

[0019] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0020] Specific implementation examples Figure 1-4 As shown, the radar antenna wire rope support mechanism includes a mounting frame. The key point is that the mounting frame is provided with a support component 2 and an oil brush component 3 which are matched with the wire rope 1. The support component includes a support conveyor belt 21 which is located below the wire rope 1 and is closely connected with the wire rope 1, and a first roller 22 which is matched with the support conveyor belt 21. The oil brush component 3 includes a rolling brush 31 and a rust preventive supply box 32 which is matched with the rolling brush 31. The rust preventive supply box 32 contains rust preventive. The rolling brush 31 is transmission-connected to the first roller 22 and rotates with the help of the drive of the first roller 22. The suspended steel wire rope 1 is partially supported by the support assembly 2, and the steel wire rope 1 is brushed with rust inhibitor by the oil brush assembly 3, and the steel wire rope 1 is cleaned at the same time; the specific working process of the support mechanism is that when the angle of the arc antenna needs to be adjusted, the reel rotates, and the length of the steel wire rope 1 from the two ends of the arc connecting plate to the reel is respectively retracted and released. During the retraction and release process, the steel wire rope 1 moves, generates friction with the support conveyor belt 21, drives the support conveyor belt 21 to rotate, thereby rotating the first roller 22, and the second roller 23 rotates. A roller 22 drives the rolling brush 31 to rotate. During the rotation of the rolling brush 31, the rust inhibitor is dipped into the rust inhibitor supply box 32, and the rust inhibitor is brushed onto the wire rope 1 by continuing to rotate. At the same time, dust and other impurities attached to the wire rope 1 can be brushed off to prevent the wire rope 1 from being corroded or rusted, thereby increasing the service life of the wire rope 1 and ensuring that the wire rope 1 can work normally. The retraction and extension of the wire rope 1 is used as the driving force source of the rolling brush 31, and no additional power supply is required, and the frequency of manual maintenance is reduced. The transmission ratio between the first roller 22 and the rolling brush 31 is less than 1, and relative motion is generated between the rolling brush 31 and the wire rope 1, thereby improving the brushing effect.

[0021] Furthermore, the rolling brushes 31 are arranged in pairs and adjacent to each other, the bristles 33 of the rolling brushes 31 are in contact with the surface of the wire rope 1, the bristles 33 at adjacent ends of the two rolling brushes 31 are cross-arranged, and the rust inhibitor supply box 32 is located below the rolling brush 3 and is matched with the bristles 33. During the process of retracting and releasing the wire rope 1, the bristles 33 at adjacent ends of the rolling brushes 31 cross-rub against each other and scrape off impurities attached to the bristles 33, which helps to reduce the impurities attached to the bristles 33 and achieve self-cleaning of the bristles 33.

[0022] Furthermore, the rolling brush 31 is an oil brushing conveyor belt installed on the mounting frame by means of a second roller 34, and the bristles 33 are arranged on the outer surface of the oil brushing conveyor belt. Compared with the roller, the oil brushing conveyor belt effectively increases the contact area between the bristles 33 and the wire rope 1, and can apply rust inhibitor to a longer section of the wire rope 1, thereby improving the brushing effect and efficiency.

[0023] Furthermore, the adjacent rolling brushes 31 are driven by the first roller 22 to rotate in the same direction. In this embodiment, the rolling brush 31 is rotated along the moving direction of the wire rope 1, which helps to simplify the arrangement of the transmission components between the rolling brush 31 and the first roller 22, reduce the reverse force on the wire rope 1 during the retraction and release process, and reduce the driving force required for the rotation of the reel; on the other hand, at the adjacent ends of the rolling brushes 31 rotating in the same direction, the bristles 33 on one of the rolling brushes 31 move upward, and the bristles 33 on the other rolling brush 31 move downward, which can effectively improve the scraping effect of impurities on the bristles 33.

[0024] Furthermore, a dust cover 35 is provided on the rust preventive agent supply box 32, and an opening matching the bristles 33 is provided on the dust cover 35. When the bristles 33 enter the rust preventive agent supply box 32 through the opening on the dust cover 35 to dip in the rust preventive agent, the opening on the dust cover 35 is blocked and covered, which can not only allow the bristles 33 to enter the rust preventive agent supply box 32, but also prevent foreign matter from falling from the outside from entering the rust preventive agent supply box 32.

[0025] The mounting frame is also provided with a tensioning wheel 4 matched with the steel wire rope 1. The tensioning wheel 4 is located above the steel wire rope 1 to press the steel wire rope 1 against the supporting conveyor belt 21, thereby increasing the friction between the steel wire rope 1 and the supporting conveyor belt 21, so that the supporting conveyor belt 21 can be effectively driven during the retraction and release of the steel wire rope 1, thereby ensuring that the rolling brush 31 brushes the steel wire rope 1.
