Description

Technical Field

[0001] This utility model relates to a mounting structure for a relative angle sensor. Background Technology

[0002] An aerial work platform is a mobile piece of machinery that lifts personnel, tools, and materials to a designated location in the air for work. During operation, the turntable's rotation angle needs to be monitored in real time to control the boom's movement and ensure safety. This monitoring is crucial for the continuity, stability, and reliability of the entire vehicle's operation.

[0003] Currently, the angle sensors on aerial work platforms on the market have a large amount of sway after installation, and are easily affected by off-center loads, causing the angle sensors to drift and affecting their accuracy. Utility Model Content

[0004] The technical problem to be solved by this utility model is that, in view of the shortcomings of existing relative angle sensors, the large amount of shaking after installation easily leads to the drift of the detected values. This utility model provides a relative angle sensor installation structure that can reduce the drift of the detected values ​​of the angle sensor to a certain extent.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A relative angle sensor mounting structure, including a mounting base, is characterized by the following features: A shaft seat is fixedly mounted on the fixed base, a turntable is rotatably mounted on the shaft seat, an angle sensor is mounted on the turntable, the angle sensor includes a fixed end and a rotating end, the fixed end is fixedly connected to the turntable, the rotating end is fixedly connected to the shaft seat, and the fixed base and the angle sensor are coaxially arranged, and the turntable is fixedly connected to a turntable that rotates around the fixed base; A positioning pin is provided between the bearing seat and the fixed seat to ensure that the bearing seat and the fixed seat are arranged coaxially, and a limiting pin is provided between the turntable and the bearing seat to prevent the turntable from moving axially.

[0006] This invention utilizes a turntable fixedly connected to the fixed end of the angle sensor, and a shaft seat fixedly connected to the rotating end of the angle sensor. By setting a positioning pin between the shaft seat and the fixed seat, the concentricity of the shaft seat and the fixed seat is ensured. At the same time, a limiting pin is set between the turntable and the shaft seat to further restrict the axial movement of the turntable during rotation, thereby axially limiting the turntable and the angle sensor. This reduces the amount of shaking after the angle sensor is installed, reduces the drift of the angle sensor's detection value, and improves the detection accuracy of the angle sensor.

[0007] A further improvement to the above scheme is that the limiting pin is arranged parallel to the radial direction of the turntable.

[0008] A further improvement to the above solution is that an angle sensor mounting part is provided in the middle of the bearing seat, and the rotating end of the angle sensor is connected to the angle sensor mounting part.

[0009] A further improvement to the above solution is that a boss is provided in the middle of the bearing seat, and a positioning groove is provided on the boss along the radial direction of the turntable. The limiting pin is fixedly connected to the turntable and inserted into the positioning groove.

[0010] A further improvement to the above solution is that the limiting pin is a bolt.

[0011] A further improvement to the above scheme is that the bearing seat is fixed to the fixed seat by bearing seat fixing bolts arranged along the axial direction of the turntable.

[0012] A further improvement to the above solution is that the shaft seat is fixedly connected to the turntable via a detection bracket.

[0013] A further improvement to the above solution is that one end of the positioning pin is located at the center of the fixed seat, and the other end is located at the center of the shaft seat, ensuring that the fixed seat and the shaft seat are installed concentrically.

[0014] A further improvement to the above solution is that the outer periphery of the angle sensor is covered with a protective cover to protect the angle sensor.

[0015] A further improvement to the above solution is that the protective cover is fixed to the turntable by bolts.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This invention is easy to install and disassemble, and can reduce the drift of the angle sensor's detection values ​​to a certain extent. Attached Figure Description

[0024] Please see Figure 1 - Figure 3 An embodiment of the relative angle sensor mounting structure of this utility model includes a fixed base 10. A shaft seat 1 is fixedly mounted on the fixed base 10 via shaft seat fixing bolts 4 arranged along the axial direction of a turntable 2. A turntable 2 is placed on the shaft seat 1, and an angle sensor 3 is mounted on the turntable 2. A boss 13 and an angle sensor mounting part 14 are provided in the middle of the shaft seat 1. The angle sensor 3 includes a fixed end 31 and a rotating end 32. The fixed end 31 is fixedly connected to the turntable 2 via angle sensor fixing bolts 5, and the rotating end 32 is fixedly connected to the angle sensor mounting part 14 of the shaft seat 1. The fixed base 21 and the angle sensor 3 are coaxially arranged. The turntable 2 is fixedly connected to a turntable (not shown in the figure) that rotates around the fixed base 10 via a detection bracket 12.

[0025] A positioning pin 11 is provided between the bearing seat 1 and the fixed seat 10. One end of the positioning pin 11 is located at the center of the fixed seat 10, and the other end is located at the center of the bearing seat 1, so as to ensure that the bearing seat 1 and the fixed seat 10 are installed on the same axis.

[0026] A limiting pin 8 is provided between the turntable 2 and the bearing seat 1, and the limiting pin 8 is arranged parallel to the radial direction of the turntable 2. Specifically, a positioning groove 15 is provided on the boss 13 along the radial direction of the turntable 2, and the limiting pin 8 is fixedly connected to the turntable 2 and inserted into the positioning groove 15. The limiting pin 8 is preferably a bolt.

[0027] To protect the angle sensor 3, a protective cover 9 covers the outer periphery of the angle sensor 3. In this embodiment, the protective cover 9 is fixedly connected to the turntable 2 by cover mounting bolts 6 and 7.

[0028] In use, the bearing seat 1 is mounted on the fixed shaft 10 by the bearing seat fixing bolt 4 and will not rotate. The turntable 2 is placed on the bearing seat 1 and can rotate around the central axis of the bearing seat 1. During the rotation of the turntable 2, the limiting member 8 connected to the turntable 2 is engaged in the positioning groove 15 and rotates with the turntable 2 to achieve the purpose of axial limiting of the turntable 2 and the angle sensor 3. The angle sensor 3 is fixed on the turntable 2 by the angle sensor fixing bolt 5, and the rotating end 32 at the lower end of the angle sensor 3 is fixed to the bearing seat 1. When the turntable 2 rotates with the turntable... When rotating, the rotating end 32 of the angle sensor 3 rotates relative to the fixed end 31, thereby detecting the rotation angle of the turntable; the detection bracket 12 and the turntable 2 have no relative movement. When the turntable and the fixed seat 10 rotate relative to each other, the detection bracket 12 drives the turntable 2 to rotate, thereby causing the rotating end 32 of the angle sensor 3 to rotate relative to the fixed end 31, realizing the detection of the rotation angle of the turntable; one end of the positioning pin 11 is located at the center of the fixed shaft 10, and the other end is located at the center of the bearing seat 1, ensuring that the fixed shaft 10 and the bearing seat 1 are concentric.
