Description

Technical Field

[0001] The utility model relates to a rangefinder fixing device which can be adjusted in multiple dimensions and belongs to the field of rangefinder auxiliary equipment. Background Art

[0002] In the scenario of loading and unloading steel coils on the production line, the automatic operation control system needs to collect the distance information of the steel coils in real time, and an infrared rangefinder can be used to achieve this function. However, infrared distance measurement has extremely high requirements for the horizontality and verticality of the equipment installation, and the actual angle range that can be used on site is narrow. Direct installation of the equipment inevitably requires repeated debugging, and the accuracy is uncontrollable.

[0003] like Figure 1 As shown, the distance between the steel coil (the object to be measured) on the production line and the end of the motor drum (the fixed background wall of the distance meter) needs to be detected in real time, and the distance information will be used in various automatic control systems. From the perspective of safety and data reliability, an infrared rangefinder is used in this scenario to realize the distance detection function. Since there is a push plate (blocking object, which cannot be removed, and there is a circular through hole with a diameter of 3 cm) between the rangefinder and the object to be measured, the infrared light of the rangefinder can only be emitted through the small through hole on the push plate for detection. After the rangefinder is welded and fixed, the situation ① (the infrared ray is horizontally consistent, but the object to be measured cannot be detected) and situation ③ (the infrared ray can be emitted to the object to be measured, but the infrared ray is skewed, which will cause the detection distance to be distorted) in the figure often occur. Only situation ② (the infrared ray can pass through the through hole horizontally and detect the object to be measured) can be correctly detected. Therefore, it is necessary to repeatedly weld, install, remove, adjust, and reinstall the rangefinder until the position of the rangefinder is appropriate. Repeated adjustments (regardless of whether the rangefinder is fixed by welding or punching) will cause irreparable damage to the background wall and cause the wall surface to be uneven. The subsequent installation angle is difficult to control, and it is time-consuming and labor-intensive for personnel. Therefore, it is necessary to design a convenient device that can fine-tune the position and angle of the rangefinder after one-time installation. Utility Model Content

The device has a wide range of applications and strong scalability.

[0005] The utility model utilizes the mechanical structure of the fixing device itself to realize that the fixed rangefinder can be conveniently adjusted in multiple dimensions, avoiding the complicated operation of repeatedly disassembling and assembling the rangefinder.

[0024] like Figures 2~6 As shown, a multi-dimensionally adjustable rangefinder fixing device is composed of a position regulator and an angle regulator; the specific description is as follows:

[0025] The position regulator comprises a fixed base 1 and a slide rail 2 with a T-shaped groove, the slide rail 2 is connected to the fixed base 1 through an intermediate rotating shaft 3, and the slide rail 2 can rotate 0-360 degrees around the rotating shaft 3; the slide rail 2 is a rectangular parallelepiped structure, and an inverted T-shaped groove 4 is provided at the center of the upper part; the angle regulator is arranged on the slide rail 2, and the angle regulator is composed of a slider 5, a top plate 6, a bottom plate 7, a spring 8, and a stud 9, wherein the slider 5 at the bottom thereof is located in the T-shaped groove 4 of the slide rail, and the slider 5 can slide in the T-shaped groove 4, the slider 5 is connected to the bottom plate 7, the bottom plate 7 is arranged parallel to the top plate 6, three studs 9 are evenly arranged between the bottom plate 7 and the top plate 6, and a spring 8 is arranged on the stud 9; the top plate 6 is a mounting surface for the rangefinder, and the measuring angle of the rangefinder is adjusted by adjusting the compression amount of the spring 8, so as to realize multi-dimensional adjustment of the rangefinder.

[0026] In the above device, four screw holes 10 are provided below the fixing base 1 for mounting the fixing base on the background wall.

[0027] The bottom of the intermediate rotating shaft 3 is connected with a nut, and after the position is adjusted, the position is tightened by the nut.

[0028] The bottom slider 5 of the angle adjuster is fixed in the center of the bottom plate 7; in the initial state, the bottom plate is arranged parallel to the top plate. When the measuring angle of the rangefinder needs to be adjusted, the compression amount of 1-3 springs is adjusted according to actual needs to change the inclination angle of the top plate, thereby realizing multi-dimensional change of the rangefinder angle.

[0029] Two positioning holes 11 are provided at the center of the top plate for mounting the rangefinder; the top plate 6 is the mounting surface of the rangefinder.

[0030] The specific usage is as follows:

[0031] First through Figure 1 The circular through hole in the middle cover is viewed horizontally to confirm the approximate installation position of the device. Figure 2 The fixed base 1 is provided with four screw holes 10 at the bottom, which can be fixed by drilling holes in the background wall and fixing with bolts. In addition, the slide rail of this part can be adjusted by 0-360° rotation around the middle rotating shaft (with nuts, the angle of the slide rail can be fixed) fixed on the base.

[0032] Then, Figure 4 Angle adjuster insert Figure 2 The distance meter is fixed in the T-shaped groove of the middle slide rail by screws. Figure 4 Just place it on the reference surface (top plate) positioning hole in the device.

[0033] Finally, fine-tune the position and angle of the rangefinder. The specific steps are:

[0034] ①After the rangefinder is installed on the device, turn on the infrared ray of the rangefinder to observe the adjustment status;

[0035] ② Adjust the nuts on the three bolts in the angle adjuster to change the compression of the three springs, so as to adjust the three-dimensional angle of the rangefinder fixed on the reference plane until the infrared horizontality and verticality of the rangefinder meet the requirements;

[0036] ③ Then by rotating the slide rail and the position of the sliding angle adjuster, the horizontal infrared ray emitted by the rangefinder can be Figure 1 Until the circular through hole of the middle obstruction passes through;

[0037] ④After confirming the final position, tighten the middle shaft nut of the slide rail and the nut of the angle adjuster slider respectively.

[0038] Before installing this device, the rangefinder can only be fixed at a single point and cannot be adjusted. Once the infrared ray emitted by the rangefinder cannot horizontally penetrate the through hole to illuminate the measured object, it is necessary to repeatedly disassemble and assemble the rangefinder, change the position, and it is impossible to fine-tune it. The process is complicated and the installation background plate is greatly damaged. With this device, as described in the above method, it only needs to be fixed once at the position where the ray can roughly pass through the through hole. The rangefinder can be adjusted at any time by virtue of the mechanical structure of the base. Figure 6 The position can be fine-tuned and fixed within the rotating circle, and the horizontal angle can be achieved by adjusting the springs on the three studs. The structure is simple and easy to maintain.
