[0001] The utility model relates to the technical field of pipeline inspection devices, in particular to a straight-wheel driven pipeline inspection device. Background Art

[0002] The external inspection of pipelines can often be quickly carried out through manual visual inspection or scanning inspection, but the internal inspection of pipelines often requires in-depth equipment to be used for internal inspection, which requires internal inspection operations using inspection devices.

[0003] The existing pipeline inspection device lacks collision protection for the outside of the shooting end, and the overall external displacement device is not easy to flexibly adjust to adapt to different pipe diameters. Therefore, a direct-wheel drive pipeline inspection device is needed. Utility Model Content

[0004] The utility model aims to provide a straight-wheel driven pipeline inspection device, which solves the problems in the prior art that there is a lack of collision protection for the outside of the shooting end and the overall external displacement device is not easy to flexibly adjust to adapt to different pipe diameters.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a direct-wheel driven pipeline inspection device, comprising a main body, a camera is installed on the top of the main body, a protective mechanism is installed on the outside of the camera, a mounting frame is sleeved on the outside of the main body, a mounting mechanism is arranged at the end of the mounting frame, a fixed shaft is arranged on the outside of the mounting mechanism, a support leg is rotatably connected to the outside of the fixed shaft, a motor is fixedly installed on the end of the support leg, a roller is connected to the output end of the motor, the roller and the support leg are connected by a flat key, and an adjustment mechanism is installed on the outer wall of the outer side of the mounting frame.

[0006] Preferably, the protective mechanism includes a protective rubber ring, an upper mounting hoop, a sliding plate, a lower mounting hoop and a buckle. The outer wall of the protective rubber ring is fitted with an upper mounting hoop, sliding plates are symmetrically arranged at both ends of the upper mounting hoop, a lower mounting hoop is arranged below the upper mounting hoop, and a buckle is slidably installed on the outer side of the sliding plate.

[0007] Preferably, the lower mounting hoop and the upper mounting hoop are symmetrically arranged with the same structure, and the upper mounting hoop forms a detachable structure with the lower mounting hoop through a sliding sheet and a buckle.

[0008] Preferably, the installation mechanism comprises a fixing frame, a turntable and a threaded column, the turntable is rotatably installed in the end groove of the fixing frame, and the inner wall center of the turntable is integrally provided with a threaded column.

[0009] Preferably, the mounting frame forms a detachable structure through the fixing frame, the turntable, the threaded column and the main body, and the main body and the threaded column are threadedly connected.

[0010] Preferably, the adjustment mechanism includes a fixed plate, a bidirectional screw, a lifting disk, and a pull rod, the middle part of the fixed plate is rotatably mounted with a bidirectional screw, the outer side of the bidirectional screw is threadedly connected to the lifting disk, and the outer wall of the lifting disk is rotatably connected to the pull rod.

[0011] Preferably, the pull rods and the legs correspond to each other and are arranged in five groups in a ring around the outer wall of the mounting frame. The legs form a transmission structure through a fixed shaft, a lifting plate, a pull rod and a bidirectional screw.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. By setting up a protective mechanism, first, a protective rubber ring is added to the outside of the camera. The protective rubber ring is a semi-arc protective part made of vibration-damping rubber material. Two protective rubber rings are selected and symmetrically added to the outside of the camera to form a wrapping installation, and the upper mounting hoop and the lower mounting hoop are added externally for limit fixing, and then the buckles on both sides are aligned with the slide for sliding plug-in installation. The overall outer diameter of the protective rubber ring here is slightly larger than the inner diameter of the circle formed by the upper mounting hoop and the lower mounting hoop. Due to the extrusion deformation characteristics of the rubber, it can be further tightened and connected with the slide through the reaction of the rubber after the buckle installation, effectively preventing slippage and facilitating disassembly and fixation. The setting of the protective mechanism effectively protects the internal camera and reduces the damage to the camera caused by collision. The overall mounting frame set on the outside of the equipment can be regularly disassembled, replaced and repaired through the mounting mechanism at the end. By turning the turntable to drive the threaded column to rotate and take it out from one end of the main body, the movable and adjustable components on the overall equipment can be quickly disassembled, stably connected and installed, and the disassembly and assembly are convenient and fast.

[0014] 2. By setting up the adjustment mechanism, and then manually controlling the rotation of the outer bidirectional screw according to the needs of different pipe diameters, the threads arranged relatively on both sides can drive the lifting plates arranged symmetrically on both sides to perform relative movement adjustment on the outside of the mounting frame. When the lifting plates are away from the bidirectional screws, the legs can be transmitted through the pull rods to make the legs move closer around the fixed axial equipment side, so as to stably and flexibly adjust the legs arranged symmetrically on both sides for folding operations. Conversely, the bidirectional screws can be adjusted to control the legs to unfold operations to adapt to wider pipe inner diameters, ensuring that the overall equipment can effectively contact the pipe wall through the rollers at the ends of the legs, ensuring that the equipment can perform stable movement operations in the pipe, and the setting of multiple sets of legs also effectively ensures the stability of overall movement and use.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] like Figure 1-4 As shown, a straight-wheel driven pipeline inspection device includes a main body 1, which is characterized in that a camera 2 is installed on the top of the main body 1, a protective mechanism 3 is installed on the outside of the camera 2, a mounting frame 4 is mounted on the outside of the main body 1, and a mounting mechanism 5 is arranged at the end of the mounting frame 4.

[0023] The protective mechanism 3 includes a protective rubber ring 301, an upper mounting hoop 302, a sliding sheet 303, a lower mounting hoop 304 and a buckle 305. The upper mounting hoop 302 is fitted on the outer wall of the protective rubber ring 301, the sliding sheets 303 are symmetrically arranged at both ends of the upper mounting hoop 302, the lower mounting hoop 304 is arranged below the upper mounting hoop 302, and the buckle 305 is slidably installed on the outer side of the sliding sheet 303.

[0024] The lower mounting hoop 304 and the upper mounting hoop 302 are symmetrically arranged with the same structure. The upper mounting hoop 302 forms a detachable structure with the slide 303, the buckle 305 and the lower mounting hoop 304. The overall outer diameter of the protective rubber ring 301 here is slightly larger than the inner diameter of the circle formed by the upper mounting hoop 302 and the lower mounting hoop 304. Due to the extrusion deformation characteristics of the rubber, after the buckle 305 is installed, it can be further fastened to the slide 303 through the reaction of the rubber, which effectively prevents slipping and facilitates disassembly and fixation.

[0025] The mounting mechanism 5 comprises a fixing frame 501 , a rotating disk 502 and a threaded column 503 . The rotating disk 502 is rotatably mounted in an end groove of the fixing frame 501 , and a threaded column 503 is integrally provided at the center of the inner wall of the rotating disk 502 .

[0026] The mounting frame 4 forms a detachable structure with the main body 1 through the fixing frame 501, the turntable 502, the threaded column 503, and the main body 1 is threadedly connected with the threaded column 503. By rotating the turntable 502 to drive the threaded column 503 to be rotated and taken out from one end of the main body 1, the movable and adjustable components on the overall equipment can be quickly disassembled, the connection and installation are stable, and the disassembly and assembly are convenient and fast.

[0027] Example 2

[0028] like Figure 1-3 As shown, this embodiment further illustrates Example 1, a fixed shaft 6 is provided on the outside of the mounting mechanism 5, a leg 7 is rotatably connected to the outside of the fixed shaft 6, a motor 8 is fixedly installed on the end of the leg 7, a roller 9 is connected to the output end of the motor 8, and the roller 9 and the leg 7 are connected by a flat key, and an adjustment mechanism 10 is installed on the outer wall of the outer side of the mounting frame 4;

[0029] The adjusting mechanism 10 includes a fixed plate 1001, a bidirectional screw 1002, a lifting disk 1003, and a pull rod 1004. The bidirectional screw 1002 is rotatably installed in the middle of the fixed plate 1001, the outer side of the bidirectional screw 1002 is threadedly connected to the lifting disk 1003, and the outer wall of the lifting disk 1003 is rotatably connected to the pull rod 1004.

[0030] The pull rod 1004 and the support leg 7 correspond to each other and are arranged in five groups in a ring around the outer wall of the mounting frame 4. The support leg 7 forms a transmission structure through the fixed shaft 6, the lifting plate 1003, the pull rod 1004 and the bidirectional screw 1002. The overall equipment can effectively contact the pipe wall through the roller 9 at the end of the support leg 7, ensuring that the equipment can be stably moved in the pipe. The setting of multiple groups of support legs 7 also effectively ensures the stability of overall movement and use.

[0031] Working principle: First, install the protective rubber ring 301 on the outside of the camera 2. The protective rubber ring 301 is a semi-arc protective part made of vibration-damping rubber material. Two protective rubber rings 301 are symmetrically installed on the outside of the camera 2 to form a wrapping installation, and the upper mounting hoop 302 and the lower mounting hoop 304 are installed on the outside to limit and fix them, and then the buckles 305 on both sides are aligned with the sliding sheet 303 for sliding plug-in installation. Here, the overall outer diameter of the protective rubber ring 301 is slightly larger than the inner diameter of the circle formed by the upper mounting hoop 302 and the lower mounting hoop 304. Due to the extrusion deformation characteristics of rubber, it can After the buckle 305 is installed, it is further tightened and connected to the slide 303 through the reaction of the rubber, which effectively prevents slipping and facilitates disassembly and fixation. The setting of the protective mechanism 3 effectively protects the internal camera 2 and reduces the damage to the camera 2 caused by collision. The overall mounting frame 4 set on the outside of the equipment can be regularly disassembled, replaced and repaired through the mounting mechanism 5 at the end. By rotating the turntable 502 to drive the threaded column 503 to rotate and be taken out from one end of the main body 1, the movable and adjustable components on the overall equipment can be quickly disassembled, stably connected and installed, and the disassembly and assembly are convenient and fast.

[0032] Then, according to the needs of different pipe diameters, the rotation of the outer bidirectional screw 1002 is manually controlled so that the threads arranged relatively on both sides can drive the lifting plates 1003 arranged symmetrically on both sides to perform relative movement adjustment on the outside of the mounting frame 4. When the lifting plate 1003 is away from the bidirectional screw 1002, the support legs 7 can be transmitted through the pull rod 1004, so that the support legs 7 are moved closer to the equipment side around the fixed axis 6, so as to stably and flexibly adjust the support legs 7 arranged symmetrically on both sides for folding operation. On the contrary, the bidirectional screw 1002 can be adjusted to control the support legs 7 to unfold operation to adapt to the wider inner diameter of the pipeline, thereby ensuring that the overall equipment can effectively contact the pipe wall through the rollers 9 at the ends of the support legs 7, ensuring that the equipment can perform stable movement operation in the pipe, and the setting of multiple groups of support legs 7 also effectively ensures the stability of overall movement and use.
