Description

Technical Field

[0001] The present invention relates to the technical field of antenna assembly, and in particular to a combined hoisting device and method for weak-rigidity large-size antenna units. Background Art

[0002] Antenna units are a crucial component of radar antenna arrays. Their function is to transmit signals generated by internal components and receive reflected echoes, converting the echo energy and returning it to the components for analysis and calculation. The antenna unit assembly is the product of antenna unit integration. While this modular, integrated unit assembly facilitates subsequent electromagnetic signal debugging, it also presents significant challenges to the overall assembly and turnover of the unit assembly.

[0003] Traditional antenna unit assembly installation relies on manual handling, where the unit assembly structural components are lifted to the mounting location on the array frame, adjusted, lowered, and fasteners tightened. This method is only suitable for small and lightweight unit assemblies, such as antenna unit assemblies ≤2m in length and ≤8kg in weight. It is no longer suitable for increasingly integrated antenna unit assemblies. Integration increases size and weight, and simultaneously reduces structural rigidity. In this case, manual lifting and installation can easily cause deformation and damage to the antenna unit assembly, making it difficult to ensure the integrity of the unit assembly during installation. Furthermore, the dense arrangement of unit assembly antennas on the array frame reduces the space for manual operation. Therefore, manual lifting and installation is no longer suitable for weakly rigid, large-sized antenna unit assemblies. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention provides a device and method for hoisting a large-sized antenna unit assembly with weak rigidity, which solves the problems raised in the above-mentioned background technology.

[0011] The front side of the bottom of the adjustment plate is fixedly connected with a balancing plate, and the bottom of the seat plate is provided with a through slot adapted to the balancing plate.

[0012] The present invention is further configured as follows: the combined rod includes several square tubes, one end of the square tube is fixedly connected to a male head, the other end of the square tube is provided with a female groove, the male head and the female groove are used in conjunction with each other, and adjacent square tubes are fixed by butt bolts.

[0013] The present invention is further configured as follows: the square frame is sleeved and slidably mounted on the outer periphery of the square tube, the bottom and the bottom of the inner cavity of the square frame are fixedly connected with positioning blocks, and the top and the bottom of the square tube are provided with long slots for use with the positioning blocks;

[0014] A friction pad is embedded in the back of the square tube, a fastening bolt is passed through and threadedly installed on the back of the square frame, and one end of the fastening bolt is in contact with and matched with the back of the friction pad.

[0015] The present invention also discloses a method for using a weak-rigidity large-size antenna unit combined hoisting device, which specifically includes the following steps:

[0016] Step 1: Assemble several square tubes according to the length of the antenna to be hoisted.

As long as the handle 404 is rotated, the first support seat 401 and the second support seat 402 can be driven closer to or away from each other, providing conditions for the horizontality of the square cylinder 601.

[0042] As a preferred solution, in order to adapt to different lifting points, the adapter plate 5 includes a square frame 501, the first support seat 401 is rotatably installed on the top of the square frame 501 through a pin shaft, the bottom of the square frame 501 is fixedly connected to a trapezoidal plate 502, and the bottom of the trapezoidal plate 502 is fixedly connected to a seat plate 503.

In order to ensure the relative stability of the position of the square frame 501, a friction pad 606 is embedded in the back of the square cylinder 601, and a fastening bolt 507 is passed through and threadedly installed on the back of the square frame 501, and one end of the fastening bolt 507 is in contact with the back of the friction pad 606.

[0043] In this embodiment, the stable hoisting of the weak-rigidity large-size antenna unit combination can be conveniently achieved.

[0044] Example 2. This example is an improvement on the previous example. In order to adapt to the different heights of the lifting points, a weak-rigidity large-size antenna unit combination lifting device is provided. A balancing component 7 is provided on the top of the base plate 503. The balancing component 7 includes an adjustment plate 701. A rubber pad 702 is embedded on the top of the adjustment plate 701.

[0045] The advantage of the second embodiment over the first embodiment is that it can adapt to hoisting points at different heights, and provide reliable guarantee for uniform force on the weak-rigidity large-size antenna unit combination during the hoisting process.

[0046] The method for using the above-mentioned weak-rigidity large-size antenna unit combined lifting device specifically includes the following steps:

[0047] Step 1: Assemble several square tubes 601 according to the length of the antenna to be hoisted. During the process, insert the male connector 602 of one square tube 601 into the female groove 603 of another square tube 601 and tighten the docking bolts 604 to complete the assembly of the two square tubes 601. After completing the assembly of several square tubes 601 in sequence, the number of hoisting points of the antenna to be hoisted is used as the number of hoisting components 3 on the combined rod 6. Push the square frame 501 to slide on the square tube 601, move the base plate 503 to the hoisting point, and then tighten the fastening bolts 507 to complete the assembly of the hoisting component 3.

[0048] Step 2: Pass the lifting rope 2 through the lifting ring 406 and hang it on the boom 1. Lift the boom 1 by the crane. The boom 1 drives the lifting rope 2 to pull up the lifting ring 406, so that the hoisting assembly 3 is in a suspended state. Determine whether the levelness of all hoisting assemblies 3 meets the requirement of 1mm / m. If it does not meet the requirement, turn the corresponding handle 404 of the corresponding hoisting assembly 3. The handle 404 drives the two screws 403 to rotate, and adjust the distance between the first support base 401 and the second support base 402 until the levelness requirement is met.

[0049] Step 3: Move the suspended hoisting assembly 3 to the hoisting point and observe whether the horizontal heights of several hoisting points are consistent. If not, after one hoisting assembly 3 is lifted up and contacts the hoisting point, adjust the heights of the remaining hoisting assemblies 3, that is, rotate the screw rod 704, the screw rod 704 drives the slider 703 to slide in the slot 504, and the slider 703 drives the adjustment plate 701 to move until the adjustment plate 701 drives the rubber pad 702 to contact the hoisting point;

[0050] Step 4: Continue to lift the boom 1 upwards while driving, and then pull several lifting ropes 2 to enable the lifting assembly 3 to lift the antenna to be lifted and move it to the target position.

[0051] As an extended explanation, in order to achieve stable and efficient assembly of weak rigidity large-size antenna unit combinations, in view of the characteristics of the antenna unit combination being tightly arranged on the array frame, and in order to meet the requirement of installing the antenna unit combination from one side, the center of gravity of the adapter plate 5 is adjusted to the axis of the lifting rope 2, and the antenna unit combination is kept in a vertical state when it is hoisted, which facilitates the tight arrangement between the antenna unit combination and the unit combination on the array frame.
