As shown in fig. 2, in some embodiments, the lifting part 22 is provided with three stages of lifting assemblies, and the first lifting assembly to the third lifting assembly are a first lifting cylinder 221, a second lifting cylinder 222 and a third lifting cylinder 223 with gradually reduced cylinder diameters; wherein, the first end of the first lifting cylinder 221 is connected to the supporting body 21, the second end of the first lifting cylinder 221 is sleeved with the first end of the second lifting cylinder 222, the second end of the second lifting cylinder 222 is sleeved with the first end of the third lifting cylinder 223, and the second end of the third lifting cylinder 223 is connected to the detecting unit 1.

Specifically, the application is provided with three stages of lifting components, and the lifting components are respectively a first lifting cylinder 221, a second lifting cylinder 222 and a third lifting cylinder 223 in a trend of gradually reducing the cylinder diameter. To the arrangement of the detection device of tertiary lifting assembly, the first end of the first lifting cylinder 221 is connected with the supporting main body 21, the second end of the first lifting cylinder 221 is sleeved with the first end of the second lifting cylinder 222, the second end of the second lifting cylinder 222 is sleeved with the first end of the third lifting cylinder 223, the detection unit 1 is connected with the second end of the third lifting cylinder 223 at the tail end of the tertiary lifting assembly, and the adjustment of the height of the detection unit 1 is achieved through the lifting movement of the tertiary lifting cylinder.

As shown in fig. 2, in some embodiments, the drive assembly includes a first pulley 2221, a second pulley 2222, a belt 224, a driven gear 2223, a rack 2211, and a drive rod 2231; the first belt pulley 2221 and the second belt pulley 2222 are rotatably connected to both ends of the inner wall of the second lifting cylinder 222, respectively, and the first belt pulley 2221 and the second belt pulley 2222 are in driving connection by the belt 224; the driven gear 2223 is coaxially connected with the first belt pulley 2221, the outer diameter of the driven gear 2223 is larger than that of the first belt pulley 2221, through grooves 2225 are formed in two sides of the second lifting cylinder 222 corresponding to one end of the first belt pulley 2221, and the driven gear 2223 can at least partially penetrate through the through grooves 2225 and be exposed out of the second lifting cylinder 222; the driving part is arranged in the second lifting cylinder 222, and the driving end of the driving part is in meshed connection 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 in meshed connection with the driven gear 2223; both ends of the transmission rod 2231 are respectively connected with the belt 224 and the third lifting cylinder 223.

Specifically, in the present embodiment, the working principle is: the driving end of the driving part is meshed with the driven gear 2223 through the driving gear 2224, so as to drive the driven gear 2223 to rotate, so as to drive the first belt pulley 2221 coaxial with the driven gear 2223 to rotate, and thus, the two belt pulleys in the second lifting cylinder 222 rotate through the belt 224. Since one end of the first lifting cylinder 221 is connected to the supporting body 21, in order to lift the second lifting cylinder 222, a rack 2211 is disposed on the inner wall of the first lifting cylinder 221, and the rack 2211 is meshed with the driven gear 2223, so that when the driving gear 2224 drives the driven gear 2223 to rotate, the second lifting cylinder 222 lifts in the vertical direction through the rack 2211 on the inner wall of the first lifting cylinder 221. For the third lifting cylinder 223, the third lifting cylinder 223 is provided with a transmission rod 2231 connected with the belt 224, and the transmission rod 2231 can drive the third lifting cylinder 223 to lift up and down reciprocally in the vertical direction along with the reciprocal rotation of the belt 224.

Since the driven gear 2223 is required to mesh with the rack 2211 on the inner wall of the first elevation cylinder 221, the driven gear 2223 has an outer diameter larger than that of the first pulley 2221. In order to prevent the rotation of the driven gear 2223 in the second lifting cylinder from being interfered, the two sides of the second lifting cylinder 222 corresponding to one end of the first belt pulley 2221 are provided with through grooves 2225, and the driven gear 2223 can at least partially pass through the through grooves 2225 and be exposed outside the second lifting cylinder 222. It should also be noted that in this embodiment, the driving portion is disposed in the second lifting cylinder 222 to avoid interference during lifting of the lifting cylinder.

The horizontal height of the detection unit 1 in the vertical direction can be controlled through the working principle, so that detection points with different heights can be detected, the adaptability of the device is improved, and the problem of comprehensive detection of the detection points with different heights is solved. Note that the lifting movement range of the second lifting cylinder 222 is related to the length of the rack 2211 provided on the inner wall of the first lifting cylinder 221 in the vertical direction, and the lifting movement range of the third lifting cylinder 223 is related to the length of the belt 224 in the vertical direction between the first belt pulley 2221 and the second belt pulley 2222, so that the length setting of the rack 2211 or the belt 224 described above can be adjusted as needed.

It should be noted that, in addition, the first lifting cylinder 221, the second lifting cylinder 222 and the third lifting cylinder 223 may be influenced by gravity vertically downward in the lifting process in the vertical direction, so that the locking or limiting design may be performed for the driving end of the driving portion. Because the drive end of drive portion passes through drive gear 2224 and driven gear 2223 meshing connection, in order to prevent to receive vertical decurrent gravity influence to make the drive end reverse rotation, can set up the drive end of drive portion for worm gear's drive form, also can add locking spacing element such as establishing telescopic link or spacing clamping piece for the drive end.

In some embodiments, driven gear 2223 is an incomplete gear.

Specifically, in order to achieve intermittent lifting of the present device lifting section 22, the driven gear 2223 is provided as an incomplete gear under the operation principle of the above-described embodiment. Since the lifting movement of the second lifting cylinder 222 relative to the first lifting cylinder 221 is achieved through the driven gear 2223 and the rack 2211 arranged on the inner wall of the first lifting cylinder 221, the driven gear 2223 is an incomplete gear, so that the driven gear 2223 cannot be in clearance fit with the rack 2211, and the second lifting cylinder 222 cannot be driven to move in a lifting manner intermittently.

The incomplete gear can be adjusted according to actual requirements, for example, when the driven gear 2223 is half of a tooth and the other half is an incomplete gear with the empty 50%, the driven gear 2223 rotates one circle, and the fit clearance with the rack 2211 is half of the time when the driven gear 2223 rotates one circle, and other percentages are the same as above. Also, for example, the incomplete gears are circumferentially arranged with teeth at a certain distance, and the teeth are not engaged with the rack 2211, thereby realizing intermittent lifting of the detecting device lifting part 22.

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

It should be noted that a second guide groove may be provided on the inner wall of the second lifting cylinder 222, and a second protrusion may be provided on the outer wall of the third lifting cylinder 223; the second protrusion may be provided on the inner wall of the second lifting cylinder 222, and the second guide groove may be provided on the outer wall of the third lifting cylinder 223, which is not limited thereto.

In some embodiments, two spiral slides with opposite rotation directions are provided on the inner wall of the third lifting cylinder 223, a shaft body is penetrated in the third lifting cylinder 223, two sliding blocks are provided on the outer side of the shaft body, and the two sliding blocks are respectively connected with the two slides in a sliding manner, so that the shaft body can rotate in the third lifting cylinder 223; wherein, the detection unit 1 is connected to the one end of the shaft body extending out of the third lifting cylinder 223.

Specifically, after the detection of the adjustment height corresponding to the detection device of the present application, the rotational 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 cylinder 223, in order to realize the rotation of the detection unit 1 in the third lifting cylinder 223, two spiral slides with opposite rotation directions are provided on the inner wall of the third lifting cylinder 223, a shaft body is penetrated in the third lifting cylinder 223, and two sliding blocks are provided outside the shaft body corresponding to the slides. When the third lifting cylinder 223 moves up and down in the vertical direction, the shaft body in the third lifting cylinder moves in the vertical direction, so that the sliding block slides along the sliding ways, and the two sliding ways rotate oppositely and are spiral, so that the linear motion of the shaft body in the vertical direction is converted into circumferential rotary motion, and the rotary motion of the detection unit 1 can be driven by one end of the shaft body extending out of the third lifting cylinder 223, so that the detection device can detect the surrounding environment and equipment, and the detection range and the detection efficiency are improved.

In addition, two sliding blocks are further arranged on the inner wall of the third lifting cylinder 223, two spiral sliding ways with opposite rotation directions are formed for the shaft body penetrating the third lifting cylinder 223, and the same applies to the above, so that the linear motion of the shaft body in the vertical direction is converted into the circumferential rotary motion, and the rotary motion of the shaft body extending out of one end of the third lifting cylinder 223 to drive the detection unit 1 can be realized.
