Description

Technical Field

[0001] The utility model relates to the technical field of a fixed bracket for a distance measuring sensor, in particular to a bracket capable of automatically adjusting an angle. Background Art

[0002] When it is necessary to measure the distance between two platforms with relative displacement, the distance measuring sensor needs to be fixed on the moving platform for distance detection. Since the platform's running trajectory fluctuates up and down during movement, the distance measuring sensor bracket fixed on the platform will also shake a certain amount with the platform. The fixed bracket cannot automatically adjust the angle, and the distance measuring sensor plane will not be parallel to the measured plane in the distance, and there will be a certain angle (there may even be a problem that the energy beam emitted by the distance measuring sensor exceeds the edge of the measured plane). As a result, the distance measured by the distance measuring sensor is extremely inaccurate and cannot meet the measurement requirements. Utility Model Content

[0003] The purpose of the utility model is to provide a bracket capable of automatically adjusting the angle in view of the defects of the prior art, so as to solve the problems raised by the above-mentioned background technology.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] Automation: An angle sensor is used to detect the tilt angle of the bracket relative to the horizontal plane, which can convert the tilt angle into an electrical signal. The control program automatically calculates and adjusts the rotation angle of the motor according to the data measured by the angle sensor to ensure that the distance sensor plane is parallel to the measured plane. This method greatly improves the automation level of adjustment;

[0012] Accuracy: The sensor bracket with automatic angle adjustment is a device that integrates advanced sensing technology and mechanical adjustment system. It can automatically adjust the tilt angle of the sensor according to the monitored environmental changes or preset parameters, so that the distance sensor plane and the measured plane at a distance are always parallel, thus accurately measuring the data;

[0013] Precision: In order to ensure that the distance sensor bracket can accurately maintain balance, a high-precision angle sensor is required; in addition, when the motor controls the rotation of the shaft, the small gear drives the large gear to engage in mechanical transmission. Due to the difference in the number of gear ratios, the shaft can be precisely rotated, thereby making precise adjustments to the angle;

[0014] Applicability: The automatically adjustable angle bracket provides greater flexibility and adaptability, enabling use in a variety of environments and conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Rollers are installed at the four corners of the bottom of the mobile platform 1. The gearbox A3 is installed on the mobile platform 1 by bolts, the motor A2 is installed on the gearbox A3 by bolts, and the first gear 13 installed on the first driving shaft 14 in the motor A2 is meshed with the second gear 16 on the first driven shaft 15 in the gearbox A3. The gearbox B6 is installed on the side of the rotatable base 4 by bolts, the motor B5 is installed on the gearbox B6 by bolts, and the third gear 18 installed on the second driving shaft 19 in the motor B5 is meshed and connected with the fourth gear 21 on the second driven shaft 20. The second rotating shaft 17 is installed on the top of the rotatable base 4 by bolts, and the first driven shaft 15 is installed on the bottom of the rotatable base 4 by bolts. The outer frame 8 is fixed to the mobile platform 1 by welding, and the lateral angle sensor 11 and the longitudinal angle sensor 9 are electrically connected to the motor A2 and the motor B5 respectively through the controller.

[0025] The mobile platform 1 has wheels at the bottom and can be moved by other power. The entire sensor bracket is fixed on the mobile platform 1. In order to ensure that the rotatable base 4 can rotate smoothly along the axis, the outer frame 8 can be fixed on the mobile platform 1 by welding, which is more stable.

[0026] The rotatable base 4 is connected to the hole on the outer frame 8 through the second rotating shaft 17. In order to ensure the stability of rotation, it is connected to the hole on the mobile platform 1 through the first driven shaft 15 at the bottom. Bearings are installed in the upper and lower holes so that the rotatable base 4 can rotate smoothly. The second rotating shaft 17 is fixed to the rotatable base 4 by bolts or the like, and the first driven shaft 15 is connected to the rotatable base 4 by bolts or keys or the like.

[0029] In order to detect the inclination angle of the rotatable vertical board 10 during the platform movement, a lateral angle sensor 11 is connected to the lateral rotation axis 12. The lateral angle sensor 11 can sense the measured angle and convert it into a usable output signal. The output signal is transmitted to the control unit, usually a PLC, which processes these signals according to the set program and calculates the angle that needs to be adjusted and the corresponding control instructions.

[0030] The control unit sends instructions to the actuator, such as motor B5, which adjusts the angle of the rotatable base according to the instructions to restore or maintain a balanced state; the motor B5 is connected to the second driving shaft 19 and drives it to rotate. In order to precisely adjust the angle, the third gear 18 on the second driving shaft 19 in the gear box B6 drives the fourth gear 21 on the second driven shaft 20 to engage and transmit. Due to the difference in the gear ratio, precise rotation of the shaft can be achieved. The shaft and the gear are connected by a key to maintain synchronous movement.

[0031] The above embodiments only express the implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
