Description

Technical Field

[0001] The utility model relates to the field of photographing inside a pipe pile hole, and particularly relates to a device for preventing camera offset inside a pipe pile hole. Background Technique

[0002] Quality inspection is required for a large number of pipe piles used in construction projects. When using the in-hole camera method for inspection, mostly the camera is placed into the pipe pile hole. One end of the camera is provided with a body, and a rope is connected to the body. The other end of the rope can be installed on a lift or a winding machine, which facilitates the lift or the winding machine to drive the camera to adjust the height inside the pipe pile hole through the rope. Finally, dynamic video is observed and collected at the control terminal, and it can also be processed with software later to form a columnar unfolded view inside the hole.

[0003] However, since most of the connected ropes are flexible, and due to the different sizes of pipe piles, the diameters of the inner holes of pipe piles are also inconsistent. When the rope is used to put the camera into or pull it out of the pipe pile hole, there is a lack of a positioning and supporting structure, and it is very easy for the camera to shake during the lifting process, thus making it difficult for the camera to focus accurately and affecting the shooting effect.

[0004] Therefore, it is very necessary to invent a device for preventing camera offset inside a pipe pile hole. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A device for preventing camera offset inside a pipe pile hole, including a fixed seat, a base is installed at the lower end of the fixed seat, a lifting component is installed between the fixed seat and the base, a circumferentially arrayed positioning rod is installed outside the base, a roller is installed at the end of the positioning rod far away from the base, a protection component is installed at the lower end of the lifting component, a camera probe is connected inside the protection component, and a transparent glass cover is installed at the shooting end of the camera probe.

[0007] Based on the above features: When the whole device needs to be extended into the pipe pile hole, the device can be put into the pipe pile hole by using a lift or a winding machine. At this time, the lifting component can drive the positioning rod to open outwards, so that the roller at one end of the positioning rod contacts with the inner wall of the pipe pile hole. Then the device can be moved downwards, and the roller will also form a rolling friction with the pipe pile hole, which is convenient for auxiliary positioning during the movement of the device, avoiding the camera probe from shaking or offsetting and affecting the shooting effect. Finally, as the device moves, the camera probe will extend out of the protection component for shooting.

[0008] Preferably, a driving motor is installed in the middle of the end of the fixing base away from the base, a connecting rope is installed on the side of the end of the fixing base away from the base, and a rope bundler is installed at the other end of the connecting rope.

[0009] Based on the above features: The driving motor can drive the lifting component to rotate forward and backward for adjustment, and the connecting ropes can be tightened together through the rope bundler, and the end of the connecting rope away from the fixing base can be connected to a lift or a winder, which is convenient for the lift or the winder to drive the whole device to lift and move.

[0010] Preferably, lug bosses in an annular array are installed on the side of the base, and a rotating shaft is installed in the middle of the base.

[0011] Based on the above features: One end of the lifting component is connected to the output end of the driving motor through the rotating shaft, and one end of the positioning rod is movably hinged to the lug boss, which is convenient for the positioning rod to be opened or folded for adjustment.

[0012] Preferably, the lifting component includes an adjusting screw rod and a connecting seat installed at one end of the adjusting screw rod. An adjusting nut is threadedly connected to the outside of the adjusting screw rod, and a fixing plate is fixedly installed on the outside of the adjusting nut.

[0013] Based on the above features: One end of the adjusting screw rod is connected to one end of the protection component through the connecting seat. When the adjusting screw rod is driven to rotate forward and backward for adjustment, the adjusting nut can drive the fixing plate to lift and adjust.

[0014] Preferably, annularly arrayed grooves are formed on the surface of the fixing plate, a support rod is hinged inside the groove, and one side of the support rod away from the groove is movably hinged to the positioning rod.

[0015] Based on the above features: One end of the support rod can rotate inside the groove. When the fixing plate drives the support rod to move upward, the support rod can be opened and push up the positioning rod to open outward, which is convenient for the roller to contact the inner wall of the pipe pile hole with a larger diameter. When the fixing plate drives the support rod to move downward, the support rod can move closer to the adjusting screw rod. At this time, the support rod can pull the positioning rod to retract inward, which is convenient for the roller to contact the inner wall of the pipe pile hole with a smaller diameter.

[0016] Preferably, the protection component includes a protection housing A and a protection housing B. A micro cylinder is installed in the middle of the inner cavity of the protection housing A, and a cleaning cotton is installed on the inner wall of the protection housing B.

[0017] Based on the above features: The micro cylinder is located in the inner cavity of the protection housing A. The micro cylinder can drive the camera probe to stretch and adjust. When the camera probe retracts, the transparent glass cover will be located inside the protection housing B. At this time, the cleaning cotton on the inner wall of the protection housing B can wipe and clean the transparent glass cover.

[0018] Preferably, the protective shell A and the protective shell B are an integrated structure, the protective shell A is a tubular structure with one end open and the other end sealed, and the protective shell B is a tubular structure with both ends open.

[0019] Based on the above features: the sealed end of the protective shell A is fixedly connected to the connecting seat, while both ends of the protective shell B are open, which facilitates the telescopic movement of the camera probe.

[0020] The beneficial effects of the utility model are:

[0021] 1. It is convenient to position, lift and adjust the camera probe. When the camera probe is placed inside the pipe pile hole, according to the diameter of the pipe pile hole, the driving motor can drive the adjusting screw rod to adjust forward and reverse through the rotating shaft. At this time, the movable nut can drive the fixed plate to move synchronously. When the fixed plate drives the support rod to move upward, the support rod can open and lift the positioning rod to open outward, so that the roller contacts the inner wall of the pipe pile hole with a larger diameter. When the fixed plate drives the support rod to move downward, the support rod can pull the positioning rod inward and retract it, so that the roller contacts the inner wall of the pipe pile hole with a smaller diameter. This is convenient for auxiliary positioning when the camera probe moves, and avoids shaking or offset of the camera probe to affect the shooting effect.

[0022] 2. When it is necessary to shoot inside the pile hole, the micro cylinder can drive the camera probe to extend, and the camera probe can shoot the inside of the pile hole. When the camera probe retracts, the transparent glass cover will be located inside the protective shell B. At this time, the cleaning cotton on the inner wall of the protective shell B can wipe the transparent glass cover to avoid dust covering the surface of the transparent glass cover and affecting the shooting effect.

It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not used to limit the present invention.

[0029] Refer to the attached Figures 1-4 A device for preventing camera offset in a pipe pile hole provided by the present invention includes a fixed seat 1. A base 2 is installed at the lower end of the fixed seat 1. A lifting assembly 3 is installed between the fixed seat 1 and the base 2. An annular array of positioning rods 4 is installed outside the base 2. A roller 5 is installed at the end of the positioning rod 4 far from the base 2. A protection assembly 6 is installed at the lower end of the lifting assembly 3. A camera probe 7 is connected inside the protection assembly 6. A transparent glass cover 8 is installed at the shooting end of the camera probe 7.

[0030] When the whole device needs to be extended into the pipe pile hole, the device can be put into the pipe pile hole by using a lift or a winch (the settings of the fixed seat 1 and the base 2 should be smaller than the inner diameter of the pipe pile hole). Since the inner diameters of the pipe pile holes are different, at this time, the lifting assembly 3 can drive the positioning rods 4 to open outwards, so that the rollers 5 at one end of the positioning rods 4 are in contact with the inner wall of the pipe pile hole. Then, the device can be moved downwards, and the rollers 5 will also form rolling friction with the pipe pile hole, which is convenient for auxiliary positioning when the device moves, and avoids the camera probe 7 from shaking or offsetting and affecting the shooting effect. Finally, as the device moves, the camera probe 7 will extend out from inside the protection assembly 6 for shooting.

[0031] Preferably, a driving motor 11 (which can also be a micro motor or a micro motor) is installed in the middle of the end of the fixed seat 1 far from the base 2. A connecting rope 12 is installed on the side of the end of the fixed seat 1 far from the base 2. The other end of the connecting rope 12 is installed with a rope binder 13.

[0032] The driving motor 11 can drive the lifting assembly 3 to rotate forward and backward for adjustment, and the connecting ropes 12 can be tightened together through the rope binder 13.

[0036] One end of the adjusting screw rod 31 is connected to one end of the protective assembly 6 through the connecting seat 32. When the adjusting screw rod 31 is driven to adjust forward and reverse, the movable nut 33 can drive the fixing plate 34 to move up and down.

[0037] Preferably, a ring-shaped array of grooves 341 is formed on the surface of the fixing plate 34 , a support rod 342 is hinged inside the groove 341 , and a side of the support rod 342 away from the groove 341 is movably hinged to the positioning rod 4 .

[0038] One end of the support rod 342 can rotate inside the groove 341. When the fixed plate 34 drives the support rod 342 to move upward, the support rod 342 can open and lift the positioning rod 4 to open outward, making it convenient for the roller 5 to contact the inner wall of the pipe pile hole with a larger diameter. When the fixed plate 34 drives the support rod 342 to move downward, the support rod 342 can move closer to the adjusting screw rod 31. At this time, the support rod 342 can pull the positioning rod 4 inward to retract, making it convenient for the roller 5 to contact the inner wall of the pipe pile hole with a smaller diameter.

When the device is placed in the interior of the pipe pile hole, according to the diameter of the pipe pile hole, the driving motor 11 can drive the adjusting screw rod 31 to adjust forward and reverse through the rotating shaft 22. At this time, the movable nut 33 can drive the fixing plate 34 to move synchronously. When the fixing plate 34 drives the support rod 342 to move upward, the support rod 342 can open and lift the positioning rod 4 to open outward, so that the roller 5 contacts the inner wall of the pipe pile hole with a larger diameter. When the fixing plate 34 drives the support rod 342 to move upward, the support rod 342 can open and push up the positioning rod 4 to open outward, so that the roller 5 contacts the inner wall of the pipe pile hole with a larger diameter. When the support rod 342 is driven to move downward, the support rod 342 can move closer to the adjusting screw rod 31. At this time, the support rod 342 can pull the positioning rod 4 to retract inward, so that the roller 5 contacts the inner wall of the pipe pile hole with a smaller diameter. When it is necessary to shoot the inside of the pipe pile hole, the micro cylinder 63 can drive the camera probe 7 to extend. At this time, the camera probe 7 can shoot the inside of the pipe pile hole. When the camera probe 7 retracts, the transparent glass cover 8 will be located inside the protective shell B62. At this time, the cleaning cotton 64 on the inner wall of the protective shell B62 can wipe and clean the transparent glass cover 8. After the shooting is completed, the elevator or the winder can drive the entire device to rise and leave the pipe pile hole.
