Description

Technical Field

[0001] The utility model belongs to the technical field of inspection well patrol robots, and in particular relates to a rapid flow guide rod device of an inspection well patrol robot. Background Art

[0002] An inspection well is a well pipe that is connected to an underground pipeline and is vertically arranged with the underground pipeline. When an underground pipeline (horizontal well pipeline) fails, such as a blockage or a pipeline leak, the inspection well can be used to enter the underground pipeline for inspection and troubleshooting.

[0003] Because the space in underground pipelines is narrow, the air is scarce, and they are used to discharge sewage all year round, the pollution in the pipeline space is relatively high. Therefore, with the development of technology, robots are gradually being used to replace manual labor to enter underground pipelines for inspections.

[0004] Specifically, in the prior art, after the robot is lowered along the inspection well, the robot enters the underground pipeline (horizontal well pipeline) for operation, and the cables hung on the robot body are continuously released by the operator above the inspection well.

[0005] Therefore, in order to prevent the cable from scratching the inner wall of the inspection well and the corner between the inspection well and the underground pipeline, a guide rod is currently used to guide the cable. Specifically, the guide rod is inserted into the bottom of the inspection well, such as in the mud. The cable is guided downward. However, since the insertion end of the guide rod is located in the underground pipeline, especially when the water flow in the underground pipeline is relatively turbulent, the stability of the guide rod is very poor, and it is pulled by the cable, causing its distance to shake unsteadily. On the one hand, this method seriously interferes with the operation of the robot in the underground pipeline. On the other hand, the cable is unstable when it is lowered and easily scratches the well wall. Once it is broken or broken, the robot cannot continue to operate, and may even detach from the cable and be located in the underground pipeline, making it difficult to salvage.

[0006] Based on the above background, the purpose of the utility model is to provide a rapid guide rod device for an inspection well inspection robot.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0040] Example 1

[0041] like Figure 1-8 As shown, a rapid guide rod device of an inspection well inspection robot includes a rapid guide rod 1, and the lower end of the rapid guide rod 1 is equipped with a clamping mechanism that is clamped at the corner position of the inspection well. Specifically, the clamping mechanism includes a U-shaped arm 51, and the U-shaped arm 51 is equipped with a plurality of clamping wheels. Specifically, the U-shaped arm 51 is fixedly connected to a wheel axle rod, and according to the existing method, the wheel axle rod is rotatably connected to two spaced-apart clamping wheels 5. The clamping wheel 5 adopts a wheel body design with a slightly larger wheel diameter, so as to be able to fully clamp at the corner position A between the inspection well and the underground horizontal pipeline.

[0042] At the same time, the locking mechanism also includes a U-shaped embedded rod 2 fixedly connected to the bottom position of the rapids guide rod 1 (the U-shaped embedded rod 2 has two embedded ends, and the bottom of the embedded end is a conical structure. This method can increase the stability of embedding in the mud and increase the embedding depth).

[0043] At the same time, the rapid current guide rod 1 device of the inspection well inspection robot also includes a guide wheel mechanism fixedly connected to the inner wall of the U-shaped embedded rod 2. The guide wheel mechanism includes guide wheels 3 arranged at intervals on both sides, and a fixed seat plate for installing the guide wheel is welded on the U-shaped embedded rod 2, and the guide wheel 3 is rotatably connected to the fixed seat plate. A curved guide groove is provided on the guide wheel 3 (that is, the guide wheel 3 is shaped like a dumbbell).

[0044] During the operation, the robot 6 is lowered along the inspection well, and the cable it pulls is guided by the guide groove on the guide wheel. Specifically, the entire device is lowered vertically into the inspection well, and under the guidance of the guide wheel 3, the cable is kept from rubbing against the wall of the inspection well, and the corner position A between the inspection well and the underground horizontal pipeline.

[0045] At the same time, the above-mentioned two clamping wheels 5 are clamped at the corner position A between the inspection well and the underground horizontal pipeline; a triangular clamping structure is formed between the two clamping wheels 5 and the U-shaped embedded rod 2 (specifically, one embedded end of the U-shaped embedded rod 2 forms a triangular clamping structure with the two clamping wheels 5, and the other embedded end forms a triangular clamping structure with the two clamping wheels 5). In this way, the lower end of the rapids guide rod 1 is clamped at the corner position A between the inspection well and the underground horizontal pipeline to maintain a very high stability. Secondly, even during work, the rapids guide rod 1 can maintain a very high stability and will not shake violently, resulting in low operating stability of the robot 6.

[0046] The above method greatly improves the stability and safety of the inspection robot 6 during underground operations.

[0047] The U-shaped arm 51 can be detachably mounted on the upper end of the U-shaped embedded rod 2; specifically, the inner end of the U-shaped embedded rod 2 is fixedly connected with a connecting seat, the upper end of the U-shaped embedded rod 2 is welded with a mounting seat, and the mounting seat is threadedly connected with a plurality of connecting screws, which are fastened to the connecting seat.

[0048] At the same time, when the entire device is lowered vertically, the locking wheel 5 is clamped at the corner position A between the inspection well and the underground horizontal pipeline, in order to further improve the clamping stability, the above-mentioned inspection well inspection robot 6 rapids guide rod 1 device also includes a small resistance wheel mechanism. When the locking mechanism is clamped at the corner position A of the inspection well, the small resistance wheel mechanism abuts against the side wall of the inspection well.

[0049] Specifically, the small resistance wheel mechanism includes a wheel arm rod 4, the upper end of which is installed on the upper end of the rapids guide rod 1 (specifically, a locking hoop 11 is installed on the rapids guide rod 1, and the locking hoop 11 is detachable through bolts, and the locking hoop 11 is fastened to the upper end of the wheel arm rod 4 through a fastening bolt); the lower end of the wheel arm rod 4 is fixedly connected to the wheel axle rod; the small resistance wheel mechanism also includes a small resistance wheel 41 rotatably connected to the wheel arm rod.

[0050] When the entire device is lowered to the angle position A where the locking wheel 5 is clamped between the inspection well and the underground horizontal pipeline, the small contact wheel 41 contacts the wall of the inspection well to improve stability. Specifically, the small contact wheel 41 contacts downward to form a contact fulcrum.

[0051] Example 2

[0052] like Figure 1-8 As shown, based on the structure of embodiment 1, this embodiment reduces the distance between the small contact wheel 41 and the inspection well according to actual work needs. If the diameter of the inspection well is too large, the small contact wheel 41 is installed separately on a wheel arm support rod 411 vertically fixed on the rapid guide rod 1. This ensures that after the locking wheel 5 is tightened, it can contact the inner wall of the inspection well.

[0053] Example 3

[0054] like Figure 7 As shown, based on the structure of the embodiment 1, in order to increase the locking stability of the locking mechanism, the locking wheel 5 on the locking mechanism is designed as a multi-wheel system containing multiple locking wheels 5, such as the locking wheel 5 is designed as three locking wheels 7 distributed in a circular array, and the locking wheels 7 are integrally assembled through a wheel frame plate 71, and the wheel frame plate 71 is installed on the rapids guide rod 1. The advantage of this method is that: since the three locking wheels 7 are distributed in a triangle, there is a locking gap between adjacent locking wheels 7 that is adapted to the corner position A between the inspection well and the underground horizontal pipeline. Therefore, when the locking wheel of the multi-wheel system is locked in the corner position A, at this time, the corner position A is clamped in the locking gap between the two locking wheels 7, and the locking stability is further improved in this way.

[0055] Similarly, if Figure 8 As shown, the principle is the same as the above method, and the clamping mechanism can also be designed to contain four clamping wheels distributed in a circular array to further increase its clamping stability.

[0056] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
