Description

Technical Field

[0001] The present invention relates to the technical field of lifting devices, and in particular to a pipeline robot lifting mechanism. Background Art

[0002] Underground pipelines are an important part of urban functions. Due to the special nature of the underground pipeline environment, it is difficult for workers to directly enter the underground pipelines for inspection. Usually, pipeline robots are used to monitor and maintain the underground pipelines. During this process, the pipeline robots need to be placed into and recovered from the underground pipelines. The current operation is to use a lifting rope to lower and recover the pipeline robot. The problem is that the hook at the lower end of the lifting rope is not easy to remove when the pipeline robot sinks to the bottom of the well. What is more difficult is that when the pipeline robot needs to be pulled up again, it is difficult to hang the hook on the correct position of the pipeline robot, resulting in difficulties in the operation of lowering and recovering the pipeline robot. For pipelines with entrances in the middle of the well instead of at the bottom of the well, manual operation is required to go down the well. Summary of the Invention

[0025] Reference below Figures 1 to 3 A pipeline robot lifting mechanism according to an embodiment of the present invention is described.

[0026] According to an embodiment of the present invention, the pipeline robot lifting mechanism includes a lifting frame and two first hooks 310. The two first hooks 310 are respectively arranged on the left and right sides of the pipeline robot 410. The two first hooks 310 are symmetrical in structure. The lower end of the lifting frame is provided with a hook shaft 233 corresponding to the first hook 310, and the upper end of the lifting frame is provided with a pull rope or a pull rod.

[0027] For example, Figure 1 and Figure 2 As shown, two first hooks 310 are respectively provided on the left front and the right front of the pipeline robot 410, and the hook mouth of the first hook 310 faces backward; a hanging hole 232 can be set at the position corresponding to the first hook 310 at the lower end of the lifting frame, and the bottom of the hanging hole 232 is the hook shaft 233; the two hanging holes 232 on the lifting frame can be simultaneously covered on the two first hooks 310 from back to front, that is, the hook shaft 233 is hung on the first hook 310.

[0028] When in use, hang the hook shaft 233 on the first hook 310, and then control the pull rope or pull rod to lower or recover the pipeline robot 410; the two first hooks 310 are symmetrical in structure, and the two hook shafts 233 at the lower end of the lifting frame can be hung on the two first hooks 310 at the same time. The hooking and unhooking actions are simple and easy to operate, making it easy to lower and recover the pipeline robot 410.

[0029] In some embodiments of the present invention, the hook mouth of the first hook 310 faces rearward; the first hook 310 includes a first transverse section 311, a second vertical section 312 and a third transverse section 313, the first transverse section 311 is arranged to be tilted downward from front to back, the top end of the first transverse section 311 is connected to the bottom end of the second vertical section 312, the third transverse section 313 is arranged to be tilted downward from front to back, the top end of the second vertical section 312 is connected to the top end of the third transverse section 313, the front and rear dimensions of the third transverse section 313 are smaller than the front and rear dimensions of the first transverse section 311, the space between the rear end of the third transverse section 313 and the first transverse section 311 is the hook mouth, and the hook mouth is arranged on the upper side of the first transverse section 311.

[0030] like Figure 2As shown, the bottom of the first transverse section 311 is fixedly connected to the pipeline robot 410, the top of the first transverse section 311 extends upward to form the second vertical section 312, and the top of the second vertical section 312 is bent backward and downward to form the third transverse section 313, so that an "L"-shaped channel is formed in the first hook 310. After the hook shaft 233 enters from the hook mouth, the hook shaft 233 can move along the "L"-shaped channel to a position between the third transverse section 313 and the second vertical section 312, so that the hook shaft 233 is not easy to fall off from the hook accidentally; because the first transverse section 311 is tilted downward from front to back, when the lifting frame hangs freely under the action of gravity, the hook The shaft 233 can slide out of the hook mouth along the first transverse section 311, which is convenient for separating the first hook 310 from the hook shaft 233; when the pipeline robot 410 needs to be recovered, since the third transverse section 313 is tilted downward from front to back, the lifting frame is dropped downward, and the bottom of the lifting frame hits the third transverse section 313 and then slides backward and downward, and then falls onto the first transverse section 311. At this time, pulling the lifting frame upward can make the hook shaft 233 hang on the first hook 310 along the first transverse section 311. Even if there is a certain deviation when the lifting frame is dropped, the hook shaft 233 can be accurately hung on the first hook 310, which greatly reduces the difficulty of operation.

[0031] In some embodiments of the present invention, a fourth transverse section 314 is provided between the third transverse section 313 and the first transverse section 311, and the rear end of the fourth transverse section 314 is connected to the rear end of the third transverse section 313. Figure 2 As shown, the bottom of the third transverse section 313 is bent forward to form a fourth transverse section 314, so that the hook shaft 233 can move to a position between the third transverse section 313 and the fourth transverse section 314 after entering from the hook mouth, making it less likely to fall off accidentally.

[0032] In some embodiments of the present invention, the lifting frame includes a cross bar 210, and a first telescopic rod is provided at both ends of the cross bar 210. The first telescopic rod is vertically arranged, and the first telescopic rod includes an upper rod section 220 and a lower rod section 230. The upper rod section 220 and the lower rod section 230 are movably connected up and down, and the hook shaft 233 is provided on the lower rod section 230; a pull rope or pull rod is provided on the cross bar 210. When the pipeline robot 410 needs to be recovered, since the ground inside the pipeline is not flat, the pipeline robot 410 may be tilted, and the two first hooks 310 are at different heights; when the lifting frame is lowered, one of the hook shafts 233 touches the first cross bar 210, but the other hook shaft 233 has not touched the first cross bar 210. At this time, the lifting frame can continue to be lowered downward. Since the first telescopic rod is provided, the hook shaft 233 that touches the first cross bar 210 in advance can remain in its original position, and the other hook shaft 233 can continue to descend until it touches the first cross bar 210. At this time, the lifting frame is pulled upward, and the two hook shafts 233 can be hung on the corresponding first hooks 310 at the same time, which is convenient for recovering the tilted pipeline robot 410.

[0033] In some embodiments of the present invention, the upper rod section 220 is tubular and is sleeved on the outside of the lower rod section 230. A first abutting block 221 is provided at the bottom of the upper rod section 220 and a second abutting block 231 is provided at the top of the lower rod section 230. The first abutting block 221 is provided on the lower side of the second abutting block 231, and the first abutting block 221 contacts the second abutting block 231. Figure 3 As shown, the first abutment block 221 is fixedly connected to the upper rod section 220, and the second abutment block 231 is fixedly connected to the lower rod section 230. The second abutment block 231 can move upward freely, so that the lower rod section 230 can hang down freely under the action of gravity. When the lifting frame hangs down, the lower rod section 230 can retract into the upper rod section 220 when encountering resistance.

[0034] In some embodiments of the present invention, the upper rod section 220 is in the shape of a flat tube or a square tube. This allows the cross-sectional shape of the lower rod section 230 to be adapted to the upper rod section 220, preventing the lower rod section 230 from rotating along the axial direction of the upper rod section 220. This prevents the hook shaft 233 from deflecting and thus becoming difficult to hook onto the first hook 310. The first abutting block 221 can be annular, and the second abutting block 231 can be annular.

[0035] Some pipelines are located midway through the well. Therefore, in some embodiments of the present invention, the first hook 310 is located in front of the center of gravity of the pipeline robot 410. This allows the center of gravity of the pipeline robot 410 to be within the pipeline, allowing the first hook 310 to protrude outward, facilitating connection or disconnection between the lifting frame and the first hook 310.

[0036] In some embodiments of the present invention, the hook opening of the first hook 310 faces rearward, and a second hook is provided behind the first hook 310. The first hook 310 and the second hook are symmetrical in structure, and the second hook is provided in the middle of the pipeline robot 410. This allows the appropriate hook to be selected for lowering or retrieving the pipeline robot 410 according to the on-site environment, making the present invention more adaptable to the environment.

[0037] In some embodiments of the present invention, the first hook 310 and the second hook are integrally formed, which facilitates production and simultaneous installation of the first hook 310 and the second hook on the pipeline robot 410 .

[0038] In some embodiments of the present invention, a pull rod is provided at the upper end of the lifting frame, and the pull rod is the second telescopic rod 110. Compared with the pull rope, the pull rod can control the lifting frame to tilt slightly, so that the hook shaft 233 is hung on the first hook 310.

[0039] The above specifically describes the preferred embodiments of the present invention, but the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
