Description

Technical Field

[0001] This application relates to the field of GNSS antenna technology, and in particular to a GNSS antenna assembly device for engineering machinery. Background Technology

[0002] GNSS antennas are the core components of satellite navigation systems for signal reception. Through multi-constellation signal compatibility, centimeter-level positioning technology, and anti-interference design, they provide support for high-precision positioning in complex environments.

[0003] In engineering construction, because GNSS antennas need to receive satellite signals from the air, they are often mounted on the surface of mechanical equipment, such as the hooks of tower cranes on construction sites, to achieve precise construction. At present, since it is not allowed to directly weld GNSS antenna components or drill holes in the equipment for installation, suction cups are usually used for installation and fixation. Although installation can be achieved, suction cups are not stable enough and there is a risk of falling, which poses a significant safety hazard. Utility Model Content

[0016] The present application will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present application, and therefore only show the components relevant to the present application.

[0017] like Figure 1-6 As shown, a GNSS antenna assembly device for engineering machinery includes: A fixing plate is provided at one end of the fixing plate; The movable plate is slidably mounted on the fixed plate, and the end of the movable plate away from the fixed clamping plate 4 is provided with a movable clamping plate 6. The fixed plate and the movable plate are elastically connected; The antenna body 3 is slidably mounted on the fixed plate.

[0018] The fixing plate serves as the basic load-bearing structure of the entire device. One end of the fixing plate is integrally formed or fixed with a fixing clamp 4 by bolts. The clamping surface of the fixing clamp 4 is adapted to the installation position of the engineering machinery (such as the boom and hook of an excavator), eliminating the need to drill holes in the equipment.

[0019] The movable plate is mounted on the fixed plate via a sliding structure and can slide back and forth along the length of the fixed plate. The end of the movable plate away from the fixed clamping plate 4 is also provided with a movable clamping plate 6. The fixed clamping plate 4 and the movable clamping plate 6 are arranged opposite to each other to form a clamping space.

[0020] The elastic connection structure between the fixed plate and the movable plate provides an elastic force that brings them closer together, ensuring that the clamping space can fit tightly against the installation part.

[0021] The antenna body 3 is mounted on top of the fixed plate via a sliding structure.

[0022] Compared to the suction cup fixing method in traditional background technology, the elastic clamping design achieves damage-free installation, which does not require drilling or welding on the equipment, and also effectively solves the safety problems of unstable suction cup fixing and easy falling off.

[0023] In some further embodiments, the fixed plate includes a first slide rail 1 disposed above it, and the movable plate includes a second slide rail 2. The first slide rail 1 and the second slide rail 2 together constitute a sliding track for the movable plate to slide.

[0024] A first slide rail 1 is provided above the fixed plate along the length direction. The cross section of the first slide rail 1 can be wedge-shaped to ensure that the part to be slid can only slide along the sliding direction.

[0025] The cross-section of the second slide rail 2 can also be wedge-shaped. The first slide rail 1 and the second slide rail 2 cooperate with each other to form a sliding track that constrains the sliding direction of the movable plate.

[0026] The sliding track provides precise guidance for the sliding of the movable plate, preventing the movable plate from shifting or getting stuck during the sliding process, and ensuring that the fixed clamping plate 4 and the movable clamping plate 6 always remain parallel and aligned, so that the clamping force is evenly applied to the installation part.

[0027] The overlapping part of the first slide rail 1 and the second slide rail 2 in the sliding direction is the final determined position of the antenna. The staggered setting of the first slide rail 1 and the second slide rail 2 can not only ensure the stability of the sliding process, but also avoid excessively increasing the length of the track to extend the sliding stroke.

[0028] In some further embodiments, the bottom of the antenna body 3 is provided with a base 30, which is slidably connected to a sliding rail; a first locking bolt 300 for abutting against the sliding rail is screwed onto the base 30.

[0029] The base 30 and the antenna body 3 can be connected by bolts to achieve the separate installation of the entire device, making installation more convenient.

[0030] The bottom of the base 30 is provided with a sliding slot 31, which interacts with the sliding track.

[0031] The first locking bolt 300 is screwed toward the fixing plate and is used to tighten the base 30 when the base 30 is fixed in position to limit the position of the base 30.

[0032] In some further embodiments, the fixed plate is provided with a groove 10, and the movable plate includes a sliding plate 60, which is slidably disposed in the groove 10.

[0033] The slide groove 10 is located inside the fixed plate and has openings at the top and bottom, and also has an opening at one end facing the movable clamping plate 6 so that the sliding plate 60 can slide in.

[0034] In some further embodiments, a through hole 600 is provided in the sliding plate 60 along the sliding direction, and an adjusting rod 62 is provided in the through hole 600 to stop rotation. A spring 7 is provided at one end of the adjusting rod 62 facing the fixed clamping plate 4, and the other end of the spring 7 is connected to the fixed plate. A threaded section is provided at one end of the adjusting rod 62 facing the movable clamping plate 6, and an adjusting nut 63 is screwed on the threaded section.

[0035] One end of the spring 7 is connected to the inner wall of the slide groove 10 away from the movable clamp 6, and the other end is connected to the adjusting rod 62.

[0036] The outer peripheral wall of the adjusting rod 62 is provided with a snap-fit ​​strip 620, and the inner wall of the through hole 600 is provided with a snap-fit ​​groove 601. The snap-fit ​​strip 620 and the snap-fit ​​groove 601 are slidably snapped together to prevent the adjusting rod 62 from rotating.

[0037] When the adjusting nut 63 is rotated, the adjusting rod 62 is driven to move toward or away from the fixed clamping plate 4, thereby reducing or increasing the tension of the spring 7, and further adjusting the clamping degree between the fixed clamping plate 4 and the movable clamping plate 6.

[0038] In some further embodiments, the fixed clamping plate 4 is provided with a second clamping bolt 42 facing the movable clamping plate 6, and the movable clamping plate 6 is provided with a third clamping bolt 65 facing the fixed clamping plate 4.

[0039] The second clamping bolt 42 and the third clamping bolt 65 are located opposite each other below the fixed clamping plate 4 and the movable clamping plate 6.

[0040] First, pull the movable clamping plate 6 so that it can accommodate the mechanism to be clamped between it and the fixed clamping plate 4 to achieve pre-clamping. Then, simultaneously screw the second clamping bolt 42 and the third clamping bolt 65 in opposite directions to achieve further clamping of the mechanism.

[0041] In some further embodiments, the movable clamping plate 6 is also screwed with screws 61 facing the fixed clamping plate 4, and the fixed plate is correspondingly provided with threaded holes 11.

[0042] To ensure the clamping effect, the screw 61 can be screwed toward the threaded hole 11, thereby making the movable clamping plate 6 fit more tightly with the fixed plate.

[0043] In some further embodiments, the bottom of the fixed clamping plate 4 and the movable clamping plate 6 are provided with a connecting handle 40, and the connecting handle 40 is provided with a connecting hole 41; it also includes a connecting plate 5, which is provided with a slot hole 50, and the slot hole 50 and the connecting hole 41 are connected by bolts.

[0044] To further ensure the clamping effect, a connecting plate 5 can be set up to form a ring-shaped clamping of the mechanism with the fixed clamping plate 4, the movable clamping plate 6, and the fixed plate, so as to prevent the entire device from falling directly off the mechanism and causing safety hazards when the fixed clamping plate 4 and the movable clamping plate 6 become loose.

[0045] The slot 50 on the connecting plate 5 is used to accommodate the sliding between the sliding plate 60 and the fixed plate.

[0046] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
