Description

Technical Field

[0001] The utility model relates to the technical field of pipeline inspection robots, in particular to a pipeline inspection robot which can be used for pipelines with different diameters. Background Art

[0002] Municipal pipe network refers to a series of underground pipe networks serving urban infrastructure, mainly including pipelines for water supply, drainage, gas, electricity, communication, heating and other systems. These pipe networks are an important part of modern urban operations, responsible for transporting domestic water, discharging wastewater, supplying natural gas, transmitting electricity and signals, and providing heating and other services. Since municipal pipe networks may become blocked, damaged or otherwise affect the normal operation of pipes during long-term operation, these pipes need to be cleaned or repaired regularly.

[0003] Before cleaning or repairing the municipal pipe network, these pipes need to be inspected. Currently, pipe inspection robots are often used to inspect municipal pipe networks. After entering the drainage pipe, the camera on the robot will take pictures of the inner wall of the pipe and transmit the image data to the control computer to assist the operator in judging the rupture, corrosion and weld quality of the pipe.

[0004] In the prior art, the patent with the patent authorization announcement number CN214374358U discloses a pipeline detection device, including a head module, a lifting module and a main control drive module; the main control drive module includes a drive bin and an oil seal bin installed on the drive bin, an aviation plug connector, a crawling tire, an anti-collision rod and a handle; the lifting module includes a lifting bin and a data connector installed on the lifting bin, a lifting rod and a gas spring; the head module includes a light and lens control bin, a lens steering bin, a lens bin installed on the lens steering bin and a lens quick connector connecting the light and lens control bin and the lens steering bin; one end of the lifting rod is connected to the lifting bin, and the other end of the lifting rod is connected to the light and lens control bin; one end of the gas spring is connected to the drive bin, and the other end of the gas spring is connected to the lifting rod.

[0005] Although the pipeline inspection equipment in the above patent can automatically judge pipeline defects during inspection, with high inspection efficiency and accuracy, there are still certain defects in this pipeline inspection robot. Since the diameters of municipal pipe networks are different, when the pipeline inspection robot enters the interior of pipelines with different diameters for inspection, it is necessary to first replace the tires of the pipeline inspection robot according to the diameter of the pipeline to facilitate the pipeline inspection robot to enter the pipeline. However, currently, the pipeline inspection robot has multiple tires, and most of the tires of each pipeline inspection robot are connected to the rotating shaft through multiple bolts. Therefore, it is relatively difficult to replace the tires of the current pipeline inspection robot. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the present invention provides a pipeline inspection robot that can be used for pipelines with different diameters to solve the problems raised in the background technology and make the disassembly and installation of the tire body of the robot main body simpler and more convenient.

[0007] To achieve the above object, the present invention provides the following technical solution: A pipeline inspection robot that can be used for pipelines with different diameters, including a robot main body and a rotating shaft installed on the robot main body.

A plurality of positioning components are arranged on the outer wall of the connecting block away from the rotating shaft end. The side wall of the positioning component abuts against the tire body. A protective component is connected to the side of the tire body away from the rotating shaft.

[0008] Further, the positioning component includes a positioning post, a positioning block, and an outward pushing elastic member. A plurality of equally spaced receiving grooves are formed on the circumferential side of the connecting block. Both ends of the positioning post are fixedly connected to the inner wall of the receiving groove. The positioning block is slidably connected to the positioning post. The outward pushing elastic member is sleeved on the outside of the end of the positioning post away from the positioning block. One end of the outward pushing elastic member is fixedly connected to the inner wall of the receiving groove, and the other end of the outward pushing elastic member is fixedly connected to the positioning block.

[0009] Further, the positioning block is arranged in a T shape, and a chamfer is formed on the side of the positioning block away from the outward pushing elastic member.

[0010] Further, the protective component includes a protective plate and a bolt. The protective plate is slidably connected to the side of the tire body away from the rotating shaft. The bolt is slidably connected to the middle position of the protective plate. The bolt passes through the protective plate and is threadedly connected to the connecting block.

[0011] Further, an outer ring of the side of the protective plate close to the tire body is fixedly connected with a sealing ring, and the sealing ring is elastically arranged.

The end of the insertion rod passes through the positioning hole and extends into the interior of the insertion hole.

[0013] Furthermore, chamfers are provided on the circumferences of the ends of the insertion rods away from the protection plate.

[0014] Compared with the prior art, the present utility model has the following beneficial effects:

[0015] For this pipeline inspection robot that can be used for pipelines with different diameters, when replacing the tire body, only need to remove the bolts, then take out the protection plate, press the positioning block into the storage groove, then the tire body can be removed. Subsequently, put the new tire body on the connecting block, release the positioning block, and the positioning block is pushed out by the outward pushing elastic member, and the tire body is fixed by the positioning block. Then install the protection plate on one side of the tire body and fix it with bolts. The replacement process of a single tire only requires turning a single bolt, which improves the replacement efficiency of the tire body and makes the replacement of the tire body simpler and more convenient.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] Please refer to Figures 1-5, A pipeline inspection robot applicable to different pipe diameters, including a robot main body 1 and a rotating shaft 2 installed on the robot main body 1. One end of the rotating shaft 2 far away from the robot main body 1 is fixedly connected with a connecting block 3. A tire main body 8 is slidably connected to the connecting block 3. A plurality of positioning components are arranged on the outer wall of the connecting block 3 at the end far away from the rotating shaft 2. The side wall of the positioning component abuts against the tire main body 8. A protective component is connected to the side of the tire main body 8 far away from the rotating shaft 2.

[0024] In the pipeline inspection robot applicable to different pipe diameters of the present utility model, when replacing the tire main body 8, only need to first remove the protective component, then release the positioning component, then the tire main body 8 can be removed from the connecting block 3. Subsequently, a new tire main body 8 is sleeved on the connecting block 3, and the tire main body 8 is fixed again through the positioning component. Finally, the protective component is installed on one side of the tire main body 8. The whole replacement process is relatively simple and fast, effectively improving the replacement efficiency of the tire main body 8 and making the replacement of the tire main body 8 simpler and more convenient. In addition, the structures of the robot main body 1 and the rotating shaft 2 in the present utility model are similar to those of a pipeline detection device disclosed in a patent with the patent authorization announcement number CN214374358U in the prior art, so no more elaboration will be made here.

[0025] As Figure 2 , Figure 3 and Figure 4 shown, the positioning component includes a positioning column 5, a positioning block 6 and an outward pushing elastic member 7. A plurality of equally spaced receiving grooves 4 are formed on the circumferential side of the connecting block 3. Both ends of the positioning column 5 are fixedly connected with the inner wall of the receiving groove 4. The positioning block 6 is slidably connected with the positioning column 5. The outward pushing elastic member 7 is sleeved on the outside of the end of the positioning column 5 far away from the positioning block 6. One end of the outward pushing elastic member 7 is fixedly connected with the inner wall of the receiving groove 4, and the other end of the outward pushing elastic member 7 is fixedly connected with the positioning block 6.

[0026] Specifically, before installing the tire main body 8, first press the positioning block 6 into the receiving groove 4, then sleeve the tire main body 8 on the connecting block 3. Subsequently, only need to push the tire main body 8 to the end of the connecting block 3 close to the rotating shaft 2 and release the positioning block 6. The positioning block 6 will pop out of the connecting block 3 under the action of the outward pushing elastic member 7, thereby fixing the tire main body 8. The fixing method is relatively simple and fast.

[0027] As Figure 3 shown, the positioning block 6 is arranged in a T shape, and a chamfer is formed on the side of the positioning block 6 far away from the outward pushing elastic member 7. The positioning block 6 with a chamfer is easier to pop out of the receiving groove 4.

[0028] As Figure 4 and Figure 5As shown, the protection component includes a protection plate 10 and a bolt 12. The protection plate 10 is slidably connected to the side of the tire body 8 away from the rotating shaft 2, and the bolt 12 is slidably connected to the middle position of the protection plate 10. The bolt 12 passes through the protection plate 10 and is threadedly connected to the connecting block 3.

[0029] Specifically, after the tire body 8 is installed on the connecting block 3, the protection plate 10 can be installed on the side of the tire body 8 away from the rotating shaft 2 and reinforced by the bolt 12. In this way, the probability of impurities entering the storage groove 4 can be reduced, and the connecting block 3 is not easily damaged.

[0030] As Figure 4 and Figure 5 shown, an outer ring of the side of the protection plate 10 close to the tire body 8 is fixedly connected with a sealing ring 11, and the sealing ring 11 is elastically arranged. The sealing ring 11 improves the sealing effect and further reduces the probability of impurities entering the inside of the connecting block 3.

[0031] As Figure 3 , Figure 4 and Figure 5 shown, a positioning hole 14 is formed in the positioning block 6, a plurality of jacks 9 are formed in the tire body 8, and a plurality of inserting rods 13 are fixedly connected to the side of the protection plate 10 close to the tire body 8. The end of the inserting rod 13 passes through the positioning hole 14 and extends into the inside of the jack 9.

[0032] Specifically, during the process of installing the protection plate 10 on one side of the tire body 8, the inserting rod 13 will be inserted into the positioning hole 14 and the jack 9, making the connection between the positioning block 6 and the tire body 8 closer, and making it easier for the rotating shaft 2 to drive the tire body 8 to rotate.

[0033] As Figure 5 shown, chamfers are provided on the circumferential sides of the ends of the inserting rods 13 away from the protection plate 10. The chamfers are provided to facilitate the insertion of the inserting rods 13 into the positioning hole 14 and the jack 9.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
