Description

Technical Field

[0001] This utility model relates to the field of airport runway surveillance radar installation technology, specifically to an airport runway surveillance radar pole leveling device. Background Technology

[0002] When installing airport runway surveillance radar, it is essential to ensure the verticality of the poles (installation foundation) and to regularly check for any tilting. Currently, the poles are installed by pre-embedding the lower end within the concrete layer of the civil engineering construction, waiting for the concrete to set. However, this method presents the following problems: 1. It is difficult to guarantee the verticality of the poles after the concrete has set; 2. Adjusting the poles to maintain verticality is quite troublesome if tilting is detected during later inspections. Utility Model Content

[0003] The purpose of this invention is to provide a reasonably structured and reliable airport runway surveillance radar pole leveling device, which solves the problem that pre-embedded poles are not easy to maintain verticality. Compared with the existing technology, it also facilitates the monitoring of the pole's verticality at any time, making it convenient to adjust the verticality of the pole in subsequent operations, that is, to adjust the levelness of the upper end face of the pole, so that the entire radar system has better stability during installation and subsequent use.

[0004] The technical solution of this utility model is:

[0005] A leveling device for an airport runway surveillance radar pole includes a pole. The key technical features are: a support plate perpendicular to the pole is fixed to its lower end; multiple through holes are evenly distributed along the edge of the support plate; a longitudinal screw is inserted through each through hole; a lower adjusting nut assembly and an upper locking nut assembly are mounted on the longitudinal screw; the support plate is clamped between the lower adjusting nut assembly and the upper locking nut assembly; a pre-embedded part is provided at the lower end of the longitudinal screw; and a steel support parallel to the upper surface of the pole is fixed to the upper part of its outer peripheral wall. A magnetic level is provided on the upper surface of the steel support.

[0006] The aforementioned airport runway monitoring radar pole leveling device has a positioning slot on the upper surface of the steel support corresponding to the magnetic level.

[0007] The aforementioned airport runway surveillance radar pole leveling device includes a lower adjusting nut assembly consisting of a lower adjusting nut, a spring washer, and a flat washer, and an upper locking nut assembly consisting of an upper locking nut, a spring washer, and a flat washer.

[0008] The aforementioned airport runway surveillance radar pole leveling device has a steel support with an arc-shaped positioning side that is in contact with the outer peripheral wall of the pole. The two ends of the arc-shaped positioning side are provided with connecting ears. The connecting ears are connected and fixed to the pole by a screw assembly, which consists of a screw, a spring washer, and a flat washer.

[0009] The aforementioned airport runway surveillance radar pole leveling device has a rectangular support plate and four through holes arranged in a square shape around the pole.

[0010] The beneficial effects of this utility model are:

[0011] The uprights do not require pre-embedding. The pre-embedded parts connected to the lower ends of the assembled longitudinal screws are fixed integrally with the concrete layer of the civil engineering construction. Observe the position of the bubble in the magnetic level and adjust the positions of the lower adjusting nut assembly and upper locking nut assembly of the longitudinal screws to center the bubble in the magnetic level, ensuring the verticality of the uprights. The upper end face of the uprights is parallel to the horizontal plane, suitable for leveling during installation and subsequent work. Adjustment is convenient and reliable, ensuring the accuracy of the radar system's installation position and the stability of the radar system during normal operation. Attached Figure Description

[0015] The present invention will be described in detail with reference to the accompanying drawings.

[0016] like Figure 1 , Figure 2 As shown, the airport runway surveillance radar pole leveling device includes a pole 4, and a support plate 12 perpendicular to the pole 4 is fixed to the lower end of the pole. The support plate 12 has multiple through holes evenly distributed along its edge. In this embodiment, the support plate 12 is rectangular, and the number of through holes is four, arranged in a U-shape around the pole 4.

[0017] A longitudinal screw 13 passes through the through hole. A lower adjusting nut assembly and an upper locking nut assembly are mounted on the longitudinal screw 13. The support plate 12 is clamped between the lower adjusting nut assembly and the upper locking nut assembly. The lower adjusting nut assembly consists of a lower adjusting nut 2, a spring washer 9, and a flat washer 10. The upper locking nut assembly consists of an upper locking nut 1, a spring washer 9, and a flat washer 10. A pre-embedded part 5 is provided at the lower end of the longitudinal screw 13.

[0018] A steel support 3, parallel to the upper surface of the outer periphery of the upright 4, is fixed to the upper part of the upright 4. A magnetic level 11 is provided on the upper surface of the steel support 3, and a positioning slot corresponding to the magnetic level 11 is provided on the upper surface of the steel support 3. The steel support 3 has an arc-shaped positioning side that is in contact with the outer periphery of the upright 4. Connecting ears are provided at both ends of the arc-shaped positioning side. The connecting ears are connected and fixed to the upright by a screw assembly, which consists of a screw 6, a spring washer 7, and a flat washer 8.
