[0034] The technical solution of the present application is described in detail below with reference to the accompanying drawings and specific embodiments, wherein the same components are denoted by the same reference numerals.

[0035] See also Figures 1 to 10 The embodiment of the present application discloses a video shooting and inspection device for super-high piers, including a camera assembly 100, a lifting assembly 200 and a support frame 300; wherein the support frame 300 is used to support the lifting assembly 200, the lifting assembly 200 is used to drive the camera assembly 100 to rise and fall, and the camera assembly 100 is used to capture images of different parts of the pier.

[0036] like Figure 2-Figure 6As shown, a lifting assembly 200 is installed at the center of the upper end of the support frame 300; the lifting assembly 200 includes an outer support tube 210, an inner guide tube 220, a lifting rod 230, a driving mechanism 240, a guide mechanism 260 and a locking sleeve 250. The upper and lower ends of the outer support tube 210 have end holes that are coaxial and connected to the inner cavity of the outer support tube 210. The main body of the inner guide tube 220 is placed in the inner cavity of the outer support tube 210, and an annular cavity is formed between the outer tube wall of the inner guide tube 220 and the inner tube wall of the outer support tube 210. The two ends of the inner guide tube 220 pass through the corresponding end holes of the outer support tube 210 and are pressed against the upper and lower end surfaces of the outer support tube 210 and fixedly sleeved on the upper and lower ends of the inner guide tube 220. The two locking sleeves 250 are locked on the outside of the outer support tube 210, the driving mechanism 240 and the guide mechanism 260 are fixed in the annular cavity in upper and lower correspondence, the cylinder wall of the inner guide cylinder 220 is provided with a driving through hole 221 and a guide through hole 222, the lifting rod 230 is movably sleeved in the inner guide cylinder 220, the rod wall of the lifting rod 230 is the driven part, the driving part of the driving mechanism 240 moves through the driving through hole 221 and is drivingly connected to the driven part, so that the driving mechanism 240 drives the lifting rod 230 to move up and down, and the guide part of the guide mechanism 260 moves through the guide through hole 222 and is tightly fitted with the driven part; the camera assembly 100 is mounted on the upper end of the lifting rod 230 and rises and falls synchronously with the lifting rod 230.

[0037] When using the super-high pier video shooting and inspection device provided by this embodiment, the support frame 300 is fixed to a suitable position on the ground, such as a flat ground, and the lifting assembly 200 is started. The driving part of the driving mechanism 240 cooperates with the driven part of the lifting rod 230 to drive and lift the lifting rod 230. At the same time, the guiding part of the guide mechanism 260 is in close contact with the driven part for guidance. The guide mechanism 260 and the driving mechanism 240 cooperate with the driven part of the lifting rod 230 at the same time, so that the lifting rod 230 can be accurately lifted and lowered in a preset direction. When the camera assembly 100 reaches the required shooting position, the lifting assembly 200 stops lifting.

[0038] This embodiment provides a super-high pier video shooting and inspection device. By adjusting the lifting component 200, the camera component 100 can reach a specified height, and can shoot pier inspection points that are inaccessible or difficult to reach by humans. Compared with the prior art in which people are sent to the specified position by large mechanical equipment for shooting, the device is safer and more economical. For piers that require daily inspections, people can operate under the piers, without occupying the road for inspection and causing no impact on traffic.

[0039] Since the height of each pier or other inspected object (such as a bridge) varies, the most common pier height is between 5m and 40m. For piers higher than 10m, the portable lifting mechanism commonly used in the prior art has poor stability and limited lifting height. For large lifting mechanisms, installation space is difficult to meet, and transportation of the lifting mechanism is time-consuming and labor-intensive. Therefore, this embodiment makes improvements to the drive mechanism 240, as follows:

[0040] like Figure 5-Figure 7 As shown, the driving mechanism 240 includes a driving motor 241, a driving wheel 242, a first clamping wheel 243, a first clamping ring 244, a first support 245 and a first clamping plate 246. The first clamping plates 246 are two pieces arranged opposite to each other, wherein the width of the middle part of each first clamping plate 246 gradually decreases toward the two ends. A driving wheel 242 is rotatably provided between the upper ends of the two first clamping plates 246. A driving motor 241 is fixed to the outer side of the upper end of any first clamping plate 246. The output shaft of the driving motor 241 is movable through the first clamping plate 246 and is driven and connected to the driving wheel 242. A first clamping wheel 243 is rotatably provided between the lower ends of the two first clamping plates 246. The first support 245 is provided to the lower ends of the two first clamping plates 246. One end of 5 is fixedly connected to the inner guide cylinder 220, and both sides of the other end of the first support 245 are hinged to the middle parts of the two first clamping plates 246. The first clamping ring 244 is fixedly arranged on the inner cylinder wall of the outer support cylinder 210. The first clamping ring 244 has a conical surface that is pressed and matched with the first clamping wheel 243. By adjusting the connection position of the locking sleeve 250 and the inner guide cylinder 220, the upper and lower relative positions of the inner guide cylinder 220 and the outer support cylinder 210 are changed, and then the position of the first clamping wheel 243 pressing against the conical surface of the first clamping ring 243 is changed, and finally the first clamping plate 246 is rotated to change the compression coefficient of the matching surface between the driving wheel 242 and the driven part, and the driven part is a rough surface.

[0041] In an embodiment of the present application, the first clamping plate 246 uses the first support 245 as a fulcrum, and both ends are tilted upward or downward. When the position of the first clamping ring 244 is moved upward, the matching position of the first clamping ring 244 and the first clamping wheel 243 changes, the first clamping wheel 243 tilts upward, and the relative driving wheel 242 and driving motor 241 tilt downward. The greater the upward angle of the lower end of the first clamping plate 246, the tighter the contact between the driving wheel 242 and the driven part, the greater the clamping force between the two, and the higher the stability of the lifting rod 230.

[0042] like Figure 6 As shown, in an optional embodiment of the present application, the upper outer wall and the lower outer wall of the inner guide cylinder 220 are both provided with external threads, and the locking sleeve 250 has an internal thread that cooperates with the external thread of the outer inner guide cylinder 220. By adjusting the positions of the upper and lower locking sleeves 250 on the inner guide cylinder 220, the position of the first clamping wheel 243 can be adjusted, and this adjustment method is simple and fast.

[0043] In an optional embodiment of the present application, there are multiple driving mechanisms 240, and they are evenly arranged along the circumference of the outer cylinder wall of the inner guide cylinder 220. Preferably, there are three, four or six driving mechanisms 240, and the number of activations is determined according to the lifting height during use. Among them, when there are three driving mechanisms 240 and they form an equilateral triangle, the three driving mechanisms 240 can form a three-claw centering effect on the lifting rod 230, ensuring that the lifting rod 230 is always on the central axis of the inner guide cylinder 220, and at the same time balancing the driving forces of the three driving mechanisms.

[0044] In an optional embodiment of the present application, there are multiple lifting rods 230, and the multiple lifting rods 230 are connected in a splicing manner. During specific use, the number of lifting rods 230 can be increased in real time according to the lifting height to meet the lifting height requirements.

[0045] It should be noted that when the number of lifting rods 230 increases, the overall weight of the lifting rods 230 will increase. At this time, it is necessary to adjust the contact position between the first pressure wheel 243 and the conical surface of the first pressure ring 243 to achieve the overall rotation of the driving device, thereby increasing the pressing force between the driving wheel 242 and the lifting rod 230, thereby achieving stable lifting of the lifting rod 243. Specifically, when the first pressure wheel 243 moves toward a position close to the lower end surface of the conical surface of the first pressure ring 243, the angle between the driving device and the inner guide cylinder 220 increases, and the relative pressing force between the driving wheel 242 and the lifting rod 230 increases. When the first pressure wheel 243 moves toward a position away from the lower end surface of the conical surface of the first pressure ring 243, the angle between the driving device and the inner guide cylinder 220 decreases, and the relative pressing force between the driving wheel 242 and the lifting rod 230 decreases.

[0046] like Figure 5 、 Figure 6 and Figure 8As shown, the guide mechanism 260 includes a guide wheel 261, a second pressing wheel 262, a second pressing ring 263, a second connecting seat 264 and a second clamping plate 265. The second clamping plates 265 are two pieces arranged opposite to each other. The guide wheel 261 is rotatably provided between the upper ends of the two second clamping plates 265, and the second pressing wheel 262 is rotatably provided between the lower ends of the two second clamping plates 265. One end of the second connecting seat 264 is fixedly connected to the inner guide cylinder 220, and both sides of the other end of the second connecting seat 264 are fixedly connected to the two second clamping plates 26 The middle portion is hinged, and the second pressing ring 263 is fixed to the inner wall of the outer support cylinder 210. The second pressing ring 263 has a conical surface that presses against the second pressing wheel 262. By adjusting the connection position of the locking sleeve 250 and the inner guide cylinder 220, the vertical relative position of the inner guide cylinder 220 and the outer support cylinder 210 is changed, thereby changing the position of the second pressing wheel 262 pressing against the conical surface. Finally, the second clamping plate 265 is rotated to change the compression coefficient of the mating surface between the guide wheel 261 and the driven part.

[0047] In the embodiment of the present application, the material of the rotating surfaces of the guide wheel 261 and the driving wheel 242 is rubber. The guide wheel 261 and the driving wheel 242 made of this material can increase the pressing force when cooperating with the driven part.

[0048] In the embodiment of the present application, there are multiple guide mechanisms 260, which are evenly arranged along the circumference of the outer cylinder wall of the inner guide cylinder 220. Preferably, the guide wheels 261 correspond to the driving wheels 242 one by one in the upper and lower directions.

[0049] In the embodiment of the present application, the driving mechanism 240 is located below the guiding mechanism 260 . In other optional embodiments, the driving mechanism 240 may also be located above the guiding mechanism 260 .

[0050] In the embodiment of the present application, since the first clamping ring 244 and the second clamping ring 263 are both fixed to the outer support cylinder 210, and the driving mechanism 240 and the guide mechanism 260 are both fixed to the inner guide cylinder 220, when the upper and lower relative positions of the inner guide cylinder 220 and the outer support cylinder 210 are adjusted, the driving mechanism 240 and the guide mechanism 260 are synchronously improved with the pressing positions of the first clamping ring 244 and the second clamping ring 263, thereby making the first clamping wheel 243 and the first clamping ring 244, the second clamping ring 263 and the second clamping ring 263 The contact positions change at the same time, and finally the degree of compression of the driving wheel 242, the guide wheel 261 and the lifting rod 230 changes at the same time, that is, by adjusting the upper and lower relative positions of the inner guide cylinder 220 and the outer support cylinder 210, the compression force of the driving mechanism 240 and the guide mechanism 260 on the lifting rod 230 can be adjusted; when the driving mechanism 240 fails, the compression force of the driving wheel 242 and the guide wheel 261 on the lifting rod 230 can be reduced by adjusting the upper and lower relative positions of the inner guide cylinder 220 and the outer support cylinder 210, thereby achieving the purpose of manual lifting.

[0051] In an embodiment of the present application, the driven part is a first concave-convex groove extending axially along the lifting rod 230 and distributed at intervals along the circumference of the lifting rod 230. The annular surfaces of the guide wheel 261 and the driving wheel 242 are both provided with damping rings. The damping rings are evenly distributed axially with second concave-convex grooves extending circumferentially along the damping rings and fitting with the first concave-convex grooves. The provision of the first concave-convex grooves and the second concave-convex grooves helps to increase the contact area between the driving wheel 242 and the lifting rod 230, thereby increasing the compression coefficient.

[0052] In other embodiments of the present application, the lifting rod (230) is a carbon fiber tube (no schematic diagram), and the driven part can be a rough surface with a high friction coefficient.

[0053] like Figure 8 As shown, the outer support cylinder 210 includes a split outer cover shell 211, an end plate 212 and an external rod 213. Multiple split outer covers 211 and end plates 212 form a cylindrical structure. An external rod 213 is sandwiched between the side edges of two adjacent split outer covers 211. The inner side of the external rod 213 is provided with a mounting portion for connecting the first clamping ring 244 and the second clamping ring 263. The structure of the mounting portion can be a screw mounting structure. The provision of the external rod 213 can facilitate the installation of the first clamping ring 244 and the second clamping ring 263.

[0055] In the embodiment of the present application, the support legs 304 are connected to the diagonal support rods 301 through threads, and the support frame 300 can be leveled by adjusting the height of the support legs 304 .

[0056] like Figure 2 As shown, connecting holes 3011 are evenly distributed axially on the outer wall of the diagonal support rod 301, and pins are inserted into the connecting holes 3011. Locking grooves are opened on the sides of both ends of the locking rod 303. The locking grooves and the pins are inserted to enable the locking rod 303 to lock the diagonal support rod 301. By selecting different connecting holes 3011, the expansion angle of the support frame 300 can be controlled.

[0057] In an embodiment of the present application, a telescopic rod is provided inside the diagonal support rod 301, and the telescopic rod is positioned by an elastic pin; the diagonal support rod 301 is hingedly connected to the outer support tube 210 at one end of the auxiliary support rod 302, and is connected to the diagonal support rod 301 at the other end by a sliding sleeve, and is provided with a locking knob 305. The locking knob 305 can be used to control the external support angle of the diagonal support rod 301, and the maximum height of the support frame 300 is not higher than 1.8m, so as to facilitate the fixation of the diagonal support rod 301.
