As shown in Figure 2, in some embodiments, the lifting part 22 is provided with three-stage lifting components. The first lifting component to the third lifting component are a first lifting cylinder 221, a second lifting cylinder 222 and a third lifting cylinder with gradually reduced diameters.

Specifically, this application is provided with three-stage lifting components, and the cylinder diameter tends to gradually decrease, namely the first lifting cylinder 221, the second lifting cylinder 222 and the third lifting cylinder 223. For the layout of the detection device of the three-stage lifting assembly, the first end of the first lifting tube 221 is connected to the support body 21, the second end of the first lifting tube 221 is sleeved with the first end of the second lifting tube 222, and the second lifting tube 222 is connected to the first end of the first lifting tube 221.

At the end of the three-stage lifting assembly, the detection unit 1 is connected to the second end of the third lifting tube 223. Through the lifting movement of the three-stage lifting tube, , to realize the adjustment of the height of the detection unit 1.

As shown in Figure 2, in some embodiments, the transmission assembly includes a first pulley 2221, a second pulley 2222, a belt 224, a driven gear 2223, a rack 2211 and a transmission rod 2231; the first pulley 2221 and the second pulley 2221. The pulleys 2222 are respectively rotatably connected to both ends of the inner wall of the second lifting tube 222. The first pulley 2221 and the second pulley 2222 are drivingly connected through the belt 224; the driven gear 2223 is coaxially connected to the first pulley 2221, and the outer surface of the driven gear 2223 The diameter is larger than that of the first pulley 2221. The second lifting tube 222 is provided with through grooves 2225 on both sides of one end of the first pulley 2221. The driven gear 2223 can at least partially pass through the through groove 2225 and be exposed outside the second lifting tube 222; The driving part is arranged in the second lifting tube 222, and the driving end of the driving part is meshed and connected with the driven gear 2223 through the driving gear 2224; the rack 2211 is arranged on the inner wall of the first lifting cylinder 221, and the rack 2211 is meshed and connected with the driven gear 2223 ; The two ends of the transmission rod 2231 are respectively connected to the belt 224 and the third lifting tube 223.

Specifically, in this embodiment, the working principle is: the driving end of the driving part is meshed with the driven gear 2223 through the driving gear 2224, driving the driven gear 2223 to rotate to drive the first pulley 2221 coaxial with it to rotate, so that The two pulleys in the second lifting tube 222 are rotated through the belt 224 . Since one end of the first lifting tube 221 is connected to the support body 21, in order to lift the second lifting tube 222, a rack 2211 is provided on the inner wall of the first lifting tube 221, and the rack 2211 meshes with the driven gear 2223, so that When the driving gear 2224 drives the driven gear 2223 to rotate, the second lifting tube 222 can be raised and lowered in the vertical direction through the rack 2211 on the inner wall of the first lifting tube 221 . For the third lifting tube 223, the third lifting tube 223 is provided with a transmission rod 2231 connected to the belt 224. As the belt 224 rotates back and forth, the transmission rod 2231 can drive the third lifting tube 223 to reciprocate in the vertical direction.

Since the driven gear 2223 needs to mesh with the rack 2211 on the inner wall of the first lifting tube 221, the outer diameter of the driven gear 2223 is larger than the first pulley 2221. In order to prevent the rotation of the driven gear 2223 in the second lifting tube from being interfered, the second lifting tube 222 has through-slots 2225 on both sides corresponding to one end of the first pulley 2221, and the driven gear 2223 can at least partially pass through the through-slots 2225. And exposed outside the second lifting tube 222.

Through the above working principle, the horizontal height of the detection unit 1 in the vertical direction can be controlled, thereby detecting detection points at different heights, improving the adaptability of the equipment, and solving the problem of comprehensive detection of detection points at different heights. It should be noted that the lifting movement range of the second lifting tube 222 is related to the length of the rack 2211 provided on the inner wall of the first lifting tube 221 in the vertical direction, and the lifting movement range of the third lifting tube 223 is related to the first pulley 2221 and The length of the vertical belt 224 between the second pulleys 2222 is related, so the length of the rack 2211 or the belt 224 can be adjusted as needed.

In addition, it should be noted that considering that the first lifting tube 221, the second lifting tube 222 and the third lifting tube 223 will be affected by vertical downward gravity during the lifting process in the vertical direction, the driving part may be The driving end is designed to be locked or limited. Since the driving end of the driving part is meshed with the driven gear 2223 through the driving gear 2224, in order to prevent the driving end from being reversed due to the influence of vertical downward gravity, the driving end of the driving part can be set in the form of a worm gear, or it can be Add telescopic rods or limiting clips and other locking limiting elements to the drive end.

Specifically, in order to realize intermittent lifting of the lifting part 22 of the device, under the working principle of the above embodiment, the driven gear 2223 is set as an incomplete gear. Since the lifting movement of the second lifting tube 222 relative to the first lifting tube 221 is realized by the driven gear 2223 and the rack 2211 provided on the inner wall of the first lifting tube 221, setting the driven gear 2223 as an incomplete gear can make the driven gear 2223 an incomplete gear. The gap between the moving gear 2223 and the rack 2211 is insufficient, so that the second lifting tube 222 is intermittently unable to be driven to move up and down.

The incomplete gear can adjust the percentage of the incomplete part in the entire gear circumference according to actual needs. For example, when half of the driven gear 2223 is an incomplete gear with teeth and the other half is 50% vacant, the driven gear 2223 rotates once. , the matching clearance between the driven gear 2223 and the rack 2211 is half the time for the driven gear 2223 to rotate once, and the other percentages are the same as above. For example, incomplete gears are circumferentially arranged with teeth spaced at a certain distance, and the teeth are spaced apart from each other and do not mesh with the rack 2211, thereby realizing intermittent lifting of the lifting part 22 of the detection device.

In some embodiments, the inner wall of the first lifting tube 221 and the outer wall of the second lifting tube 222 are provided with a first guide groove and a first protrusion, and the first protrusion is slidingly connected with the first guide groove.

Specifically, since the second lifting tube 222 moves up and down in the vertical direction relative to the first lifting tube 221, in order to guide this lifting movement, the inner wall of the first lifting tube 221 and the outer wall of the second lifting tube 222 can be A first guide groove and a first protrusion are provided, and the lifting movement is guided through the sliding connection between the first protrusion and the first guide groove.

It should be noted that a first guide groove can be provided on the inner wall of the first lifting tube 221, and a first protrusion can be provided on the outer wall of the second lifting tube 222; The outer wall of the second lifting tube 222 is provided with a first guide groove, and the two methods are not limited.

In some embodiments, the inner wall of the second lifting tube 222 and the outer wall of the third lifting tube 223 are provided with a second guide groove and a second protrusion, and the second protrusion is slidably connected to the second guide groove.

Specifically, since the third lifting tube 223 moves up and down in the vertical direction relative to the second lifting tube 222, in order to guide this lifting movement, the inner wall of the second lifting tube 222 and the outer wall of the third lifting tube 223 can be A second guide groove and a second protrusion are provided, and the lifting movement is guided through the sliding connection between the second protrusion and the second guide groove. It should be noted that a second guide groove can be provided on the inner wall of the second lifting tube 222, and a second protrusion can be provided on the outer wall of the third lifting tube 223; a second protrusion can also be provided on the inner wall of the second lifting tube 222, The outer wall of the three lifting tubes 223 is provided with a second guide groove, and the two methods are not limited.

In some embodiments, the inner wall of the third lifting tube 223 is provided with two spiral slideways with opposite rotation directions. A shaft is provided in the third lifting tube 223, and two slide blocks are provided on the outside of the shaft. The blocks are respectively slidably connected to the two slideways, so that the shaft body rotates in the third lifting tube 223; one end of the shaft body extending out of the third lifting tube 223 is connected to the detection unit 1.

Specifically, after the detection device of the present application detects the corresponding adjustment height, the rotation movement of the detection unit 1 in the horizontal direction can be achieved in the following manner. Since the detection unit 1 is connected to the second end of the third lifting tube 223, in order to realize the rotation of the detection unit 1 in the third lifting tube 223, two spiral slides with opposite rotating directions are provided on the inner wall of the third lifting tube 223. The third lifting tube 223 is provided with a shaft body, and two slide blocks are provided outside the shaft body corresponding to the slideway. When the third lifting tube 223 moves up and down in the vertical direction, the shaft inside it moves in the vertical direction, causing the slider to slide along the slideway. Since the two slideways rotate in opposite directions and are in a spiral shape, the shaft is forced to slide along the slideway. The linear motion of the body in the vertical direction is converted into a circumferential rotational motion, so that one end of the shaft body extends out of the third lifting tube 223 to drive the detection unit 1 to perform a rotational motion, so that the detection device of the present application can detect the surrounding environment and equipment. Carry out detection and improve detection range and detection efficiency.

In addition, two slide blocks can also be provided on the inner wall of the third lifting tube 223 to open two spiral slides with opposite directions for the shaft passing through the third lifting tube 223. In the same way as above, the shaft is forced to The linear motion in the vertical direction is converted into a circumferential rotational motion, so that one end of the shaft extending out of the third lifting tube 223 can drive the detection unit 1 to rotate.
