UTILITY MODEL CONTENTS

[0004] The utility model aims at overcoming the problems in prior art, and provides multi-target infrared tracking measurement device, which can change the measurement angle of infrared measuring instrument, reduce the measurement blind area of infrared measuring instrument, and has better actual use effect.

[0005] In prior art, the rotation of rocker arm is realized by the way of extending electric push rod, however, electric push rod is rotated along with rocker arm in the process of extension, when rocker arm is parallel to electric push rod, electric push rod reaches the maximum extension length, and rocker arm cannot continue to rotate, so that rocker arm has large rotation dead angle, further leads to large measurement blind area of infrared measuring instrument, and actual use effect is poor.

[0012] During the winding of the power rope on the driving shaft or the driven shaft, the power rope is closely arranged along the fixed shaft, so that the power rope is always arranged closely and the problem of loosening and slipping of the power rope is avoided. However, there is an included angle between the power rope located between the driven shaft and the driving shaft and the axial direction of the driven shaft in the above process, so that the power rope not only has a tangential friction force between the surface of the driven shaft during rotation, but also has an axial traction force between the surface of the driven shaft, so that the driven shaft has a tendency to move along the axial direction. If the position of the driven shaft is always fixed, the power rope is easily too tight, which leads to the breakage of the power rope. Therefore, the above structure is designed.

[0018] Preferably, the two ends of each sliding shaft are fixedly connected with a blocking ring.

[0037] The drawings in the utility model are not strictly drawn according to actual proportions, and the specific dimensions and quantity of each structure can be determined according to actual needs. The drawings described in the utility model are only structural schematic diagrams.

[0038] In the prior art, Figure 1 , the rotation of the rocker arm is realized by elongating the electric push rod, however, the electric push rod rotates simultaneously with the rocker arm during the elongation process, when the rocker arm and the electric push rod are parallel to each other, the electric push rod reaches the maximum elongation length, and the electric push rod cannot push the rocker arm to continue rotating, so that the rocker arm has a large rotation dead angle, further resulting in that the infrared measuring instrument has a large measurement blind area, and the actual use effect is poor. In order to further solve the above technical problems, the following is described in detail.

[0039] The multi-target infrared tracking and measuring device provided by the utility model comprises Figures 2-3 and Figure 8 an installation frame 1, and further comprises:

[0040] a power member 2 fixed on the installation frame 1, and the power member 2 has a driving shaft;

[0041] a driven shaft 3 rotationally arranged on the installation frame 1;

[0042] a power rope 4 sequentially wound on one end of the driving shaft, the driven shaft 3 and the other end of the driving shaft, and the two ends of the power rope 4 are respectively fixedly connected to the two ends of the driving shaft;

[0043] a mounting seat 5 fixedly connected to the driven shaft 3 and used for mounting the infrared measuring instrument.

[0044] The first end of the power rope 4 is fixed on one end of the driving shaft, the second end of the power rope is first wound on one end of the driving shaft, then the second end of the power rope is wound on the driven shaft 3 along the length direction of the driven shaft 3, and then the second end of the power rope is wound on the other end of the driving shaft and fixedly connected to the other end of the driving shaft; through the rotation of the driving shaft on the power member 2, the power rope 4 is simultaneously wound from the driving shaft to the driven shaft 3 and then from the driven shaft 3 to the driving shaft, the number of winding turns of the power rope 4 on the driven shaft 3 is always the same, and the power rope 4 drives the driven shaft 3 to rotate through friction force in the winding process on the driven shaft 3, so as to realize the deflection of the mounting seat 5 and the infrared measuring instrument.

[0045] The multi-target infrared tracking and measuring device avoids the problem of limited rotation angle caused by the combination of the rocker arm and the electric push rod, can change the measurement angle of the infrared measuring instrument at the maximum angle, reduces the measurement blind area of the infrared measuring instrument, and has a better actual use effect.

[0046] In this embodiment,Figures 3-5 Both ends of the driven rotating shaft 3 are coaxially fixedly connected to a limiting shaft 6 and a sliding shaft 7 in sequence. A first slider 8 along its length direction is fixedly connected to the limiting shaft 6. A limiting sleeve 9 is slidably connected to both the limiting shaft 6 and the first slider 8. The inner diameter profile of the limiting sleeve 9 is adapted to the profile of the limiting shaft 6 and the first slider 8. The limiting sleeve 9 is fixedly connected to the mounting base 5. Both sliding shafts 7 are rotatably and slidably connected to the sliding hole 10 on the mounting bracket 1.

[0047] As the power rope 4 is wound around the driving shaft or the driven shaft 3, it is tightly arranged along a fixed axial direction, which ensures that the power rope 4 is always tightly arranged and avoids the problem of the power rope becoming loose and slipping. However, in the above process, there is an angle between the power rope 4 located between the driven shaft 3 and the driving shaft and the axial direction of the driven shaft 3. Therefore, during the rotation, the power rope 4 not only has tangential friction with the surface of the driven shaft 3, but also axial traction with the surface of the driven shaft 3, which makes the driven shaft 3 tend to move along the axial direction. If the position of the driven shaft 3 is always fixed, the power rope 4 is easily too tight, which can lead to the breakage of the power rope. Therefore, the above structure is designed.

[0048] When the power rope 4 generates an axial traction force on the driven shaft 3, the sliding shaft 7 slides and rotates within the sliding hole 10 to eliminate or weaken the traction force. At the same time, the limiting shaft 6 transmits the rotational power to the limiting sleeve 9 through the first slider 8, so that the limiting sleeve 9 drives the mounting base 5 to rotate. The limiting shaft 6 and the first slider 8 slide axially relative to the limiting sleeve 9 together. The above structure ensures that the power rope 4 can be tightly arranged when wound, maintains the stability of power transmission, and avoids the problem of the power rope 4 breaking due to excessive force.

[0049] The inner wall of the limiting sleeve 9 has a groove that can slide with the first slider 8. The first slider 8 slides in the groove to limit the synchronous rotation of the limiting shaft 6 and the limiting sleeve 9.

[0050] In this embodiment, as Figures 2-3 The power component 2 is a dual-head motor. Both ends of the dual-head motor are coaxially fixedly connected to rollers 11, and the two ends of the power rope 4 are respectively wound on the rollers 11.

[0051] The dual-head motor can drive two rollers 11 to rotate synchronously. By controlling the rotation of the dual-head motor, the angle of the mounting base 5 can be changed.

[0052] In this embodiment, as Figure 6 The mounting base 5 is fixedly connected to two sides of a second slider 12, and the opposite sides of the two second sliders 12 are slidably connected to the surface of the mounting frame 1.

[0053] The second sliding block 12 is annular, semi-annular or block-shaped, preferably semi-annular, which can reduce the contact area with the mounting frame 1 and the frictional resistance, and can stably contact with the mounting frame 1; the mounting frame 1 is a U-shaped plate, the opposite inner walls of the U-shaped plate are slidably connected with the second sliding block 12, so as to limit the axial movement of the mounting seat 5; the distance between the opposite inner walls of the U-shaped plate is 20-45 cm, and the wall thickness of the side wall of the U-shaped plate is 3-8 mm.

[0054] In the embodiment, the mounting seat 5 is provided with a notch 14 for clamping the infrared measuring instrument. Figure 4 The two ends of each sliding shaft 7 are fixedly connected with a blocking ring 13.

[0055] The side surface of the blocking ring 13 is fixedly connected with the end surface of the sliding shaft 7, so as to prevent the sliding shaft 7 from sliding out of the sliding hole 10.

[0056] In the embodiment, the mounting seat 5 is provided with a notch 14 for clamping the infrared measuring instrument. Figure 6 The opposite side surfaces of the notch 14 are provided with elastic rubber pads 15.

[0057] The mounting seat 5 is a flat plate, the notch 14 is used for clamping the infrared measuring instrument, the elastic rubber pads 15 are used for increasing the friction force between the surface of the elastic rubber pads 15 and the surface of the mounting seat 5, preventing the elastic rubber pads 15 from falling off, and the two side edges of the elastic rubber pads 15 protrude from the surface of the mounting seat 5 and are arc-shaped and bent towards the middle part of the notch 14, so as to increase the holding force and adapt to infrared measuring instruments of different sizes.

[0058] In the embodiment, the mounting seat 5 is provided with a notch 14 for clamping the infrared measuring instrument. Figure 7 The mounting frame 1 is fixedly connected with an ear plate 16, and the ear plate 16 is provided with a limiting hole for penetrating a fixing member.

[0059] The fixing member includes a bolt, a screw or a rivet, and the fixing member penetrates the limiting hole in the ear plate 16 and is used for fixing the mounting frame 1 on a carrier.

[0060] The use method of the multi-target infrared tracking and measuring device is as follows:

[0061] Firstly, the fixing member penetrates the limiting hole in the ear plate 16 and fixes the mounting frame 1 on the carrier.

[0062] Then, the infrared measuring instrument is clamped in the notch 14.

[0063] Finally, the double-head motor is controlled to rotate forward or reversely, so as to drive the mounting seat 5 to rotate forward or reversely, and the infrared measuring instrument is convenient to track and measure multiple targets at a suitable angle.
