[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] The utility model aims to solve the problems that the existing pipeline monitoring device may damage the pipe wall during installation and use, is costly and dangerous. Figure 1-9 As shown, the following technical solution is provided: a pipeline stability detection vehicle, comprising: a connecting rod 2, an upper fixed structure 1 arranged at the upper end of the connecting rod 2 and a lower fixed structure 3 arranged at the lower end of the connecting rod 2, the upper fixed structure 1 comprising a fixed bracket 11 vertically arranged with the connecting rod 2 and telescopic arms 12 telescopically arranged at both ends of the fixed bracket 11, the fixed bracket 11 is provided with a telescopic driving component connecting the two telescopic arms 12, the telescopic driving component drives the telescopic arms 12 to move and telescope synchronously, the lower fixed structure 3 comprises an upper flange connecting block 32 and a lower flange connecting block 34 arranged up and down along the connecting rod 2, the lower flange connecting block 34 is connected with a sliding driving component, and the lower flange connecting block 34 is in the sliding driving component The upper flange connection block 32 and the lower flange connection block 34 are movably connected to each other to slide along the connecting rod 2. A plurality of folding strut assemblies circumferentially arranged around the connecting rod 2 are movably connected between the upper flange connection block 32 and the lower flange connection block 34. The folding strut assembly includes an upper support arm 31 and a lower support arm 35. The upper end of the upper support arm 31 is rotatably connected to the upper flange connection block 32, and the lower end of the lower support arm 35 is rotatably connected to the lower flange connection block 34. A support seat 37 is movably connected between the upper support arm 31 and the lower support arm 35. The telescopic arm 12 can be extended to support the upper end of the fixed carrier through the telescopic drive assembly. The lower fixed structure 3 can be opened and supported by the sliding drive component to fix the lower end of the carrier. The operation is safe and the detection cost is saved.

[0029] Specifically, the upper end of the connecting rod 2 can be connected to a lifting structure to facilitate placing the entire carrier into the inspected pipeline, such as a lifting rope, a hanging rod, etc., and the connecting rod 2 itself can adopt a multi-section structure, and the number of multi-section structures can be increased or decreased according to the needs of the inspection pipeline. A retractable multi-section structure can also be adopted. Various inspection equipment can be installed on the connecting rod 2, such as visual inspection equipment, temperature detection equipment, etc.

[0030] The upper fixed structure 1 can be connected to the connecting rod 2 as a separate combined module. For example, a connecting flange 4 is set between the upper fixed structure 1 and the connecting rod 2 to facilitate disassembly and installation. The upper fixed structure 1 can be disassembled during transportation, and the length of the fixed bracket 11 can also be replaced according to pipes of different diameters.

[0031] The upper support arm 31 and the lower support arm 35 are rotatably connected to the upper flange connection block 32 and the lower flange connection block 34 via the fixing pin 7, so that the upper support arm 31 and the lower support arm 35 can rotate flexibly.

[0032] The telescopic drive assembly can have various implementations, such as Figure 2-4 The figure shows a first embodiment of the telescopic drive assembly. Specifically, the telescopic drive assembly includes a screw rod 18 that passes horizontally through the fixed bracket 11 and a connecting block 15 installed at both ends of the screw rod 18 with threads. Both sides of the connecting block 15 are connected to the telescopic arm 12 on the corresponding side through a connecting arm 16. The connecting arm 16 is rotatably connected to the connecting block 15 and the telescopic arm 12. The movement of the connecting block 15 can be achieved by rotating the screw rod 18, thereby achieving the telescopic movement of the telescopic arm 12, which is very convenient and reliable. The threads at both ends of the screw rod 18 are opposite, so when the screw rod 18 rotates, the connecting blocks 15 at both ends move relative to each other or move away from each other. When the connecting block 15 moves relative to each other, the distance between one end of the connecting arm 16 on the same side is close, and the telescopic arm 12 can be pushed outward to extend the two telescopic arms 12 until the outer end of the telescopic arm 12 contacts and supports the inner wall of the pipe; when the connecting block 15 moves away from each other, the telescopic arm 12 will retract and detach from the inner wall of the pipe. In order to facilitate the rotation of the screw rod 18 , a rotating rocker arm 14 is installed at at least one end of the screw rod 18 . The rotating rocker arm 14 can facilitate the rotation operation of the screw rod 18 .

[0033] At the same time, in order to ensure the smooth rotation of the screw rod 18, a linear bearing 17 is installed at the position where the screw rod 18 passes through the fixed bracket 11, and the screw rod 18 passes through the linear bearing 17, and the linear bearing 17 can realize the stable rotation of the screw rod 18. Limiting nuts 13 are also installed at both ends of the screw rod 18, and the connecting block 15 is arranged between the two limiting nuts 13. The limiting nuts 13 can limit and lock the connecting block 15. When the outer end of the telescopic arm 12 contacts and supports the inner wall of the pipe, the limiting nuts 13 can be rotated to adjust the position to support the connecting block 15, so as to prevent the connecting block 15 from moving and realize locking.

[0034] Of course, in this embodiment, the telescopic drive assembly may also adopt other structures, such as the inner ends of the telescopic arms 12 are each provided with a rack arranged along the length direction of the fixed bracket 11, and the two racks are moved synchronously by rotating the gear in the middle to achieve synchronous extension and retraction of the two telescopic arms 12.

[0035] In order to increase the friction between the upper fixed structure 1 and the lower fixed structure 3 and the inner wall of the pipe, the side of the support seat 37 and the end of the telescopic arm 12 are installed with anti-slip pads 5, which can improve the entire detection carrier to be firmly contacted and locked with the pipe wall. The anti-slip pads 5 can be made of nylon material with good wear resistance.

[0036] As a specific embodiment of the sliding drive component, Figure 5-6 As shown, the sliding driving component is at least one pull rope 33 connected to the lower flange connecting block 34, and the pull rope 33 is arranged along the length direction of the connecting rod 2. The lower end of the pull rope 33 is connected to the connecting part 38 on the lower flange connecting block 34, and the pull rope 33 can be operated from the pipe mouth of the pipeline to realize the lifting and lowering of the lower flange connecting block 34. When the pull rope 33 pulls the lower flange connecting block 34 to rise, the upper support arm 31 and the lower support arm 35 can push the support seat 37 outward until the support seat 37 is fixed to the inner wall of the pipeline. At this time, the upper end of the pull rope 33 can be fixed to the outside of the pipeline, so that the lower flange connecting block 34 will not fall automatically. The cost of the pull rope 33 is relatively low. In actual use, the pull rope 33 is in the form of two and symmetrically connected to the two sides of the lower flange connecting block 34. The simultaneous operation of the two pull ropes 33 can improve the sliding stability of the lower flange connecting block 34.

[0037] In order to allow the lower flange connection block 34 to quickly detach from the inner wall of the pipe, an elastic member 36 is connected between the support seat 37 and the corresponding upper support arm 31 and lower support arm 35. The elastic member 36 can drive the upper support arm 31 and the lower support arm 35 to automatically open and detach from the pipe wall after the pull rope 33 is relaxed. The elastic member 36 can be a spring or an elastic rope.

[0038] like Figure 8-9 As shown, the support seat 37 includes a main body plate 9, an anti-slip pad 5 can be installed on the outer side of the main body plate 9, a pair of fixing ears 6 are centrally installed on the inner side of the main body plate 9, a fixing pin 7 is connected between the fixing ears 6, the ends of the upper support arm 31 and the lower support arm 35 are connected to the fixing pin 7, support frames 8 are arranged on both sides of the fixing pin 7, and the ends of the elastic member 36 are connected to the corresponding support frames 8, and the structure is simple and reliable.
