Description

Technical Field

[0001] This utility model relates to the field of anti-rust paint spraying technology, specifically a track-type device suitable for spraying anti-rust paint on the weld seams of large-diameter jacking pipes inside working wells. Background Technology

[0002] Currently, the application of anti-rust paint to the weld seams of pipe jacking in working shafts still relies on manual brushing. This is mostly used for small-diameter pipes where there is ample operating space for workers. However, in restrictive environments such as large-diameter pipes, confined spaces, and harsh working conditions (pungent rust paint, severe water accumulation and dampness in the working shaft), manual brushing significantly reduces work efficiency. Secondly, to protect workers, effective measures to safeguard their lives and health are required at the construction site. Furthermore, the uniformity of the anti-rust paint thickness and the width of the weld seams are constrained by factors such as the worker's skill level and sense of responsibility, potentially leading to frequent quality issues. For all these reasons, the quality of pipe jacking weld seams cannot be effectively guaranteed. Utility Model Content

[0003] In view of the above-mentioned prior art, this utility model proposes a track-type device suitable for spraying anti-rust paint on the weld seams of large-diameter jacking pipes in working wells. This device can meet the construction operation of anti-rust paint spraying on the weld seams of large-diameter jacking pipes in working wells, and can adapt to situations such as large pipe diameter and harsh working environment (the anti-rust paint has a pungent smell, and the working well is severely waterlogged and humid). Moreover, it does not require workers to directly apply the paint, fundamentally solving the problem of frequent quality problems of anti-rust paint on the weld seams of jacking pipes, and improving the quality confidence of the anti-rust paint on the weld seams of jacking pipes in working wells.

[0004] This utility model provides a track-type device for spraying anti-rust paint on the weld seams of large-diameter jacking pipes in working wells, including a ring-shaped double track arranged around the jacking pipe, and an automatic paint sprayer arranged on the inner side of the ring-shaped double track, which can move along the ring-shaped double track.

[0005] Preferably, the annular double track is fixedly connected to the well wall of the working well through several evenly arranged connecting rods.

[0006] Preferably, both the annular double rail and the connecting rod are made of round steel.

[0007] Preferably, the distance between the paint spray nozzle of the automatic paint sprayer and the surface of the pipe weld is 20-30cm.

[0008] Preferably, the automatic paint spraying machine is fixedly connected to several track rods, and both ends of the track rods are connected to the annular double track by H-shaped track wheels.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) This utility model is reasonably designed. It uses an automatic spraying machine to spray the top pipe around the ring double track. The spraying pressure is kept stable during the spraying process, which can well guarantee the thickness and width of the anti-rust paint film after spraying. (2) The device can be reused. (3) The device can improve the working conditions of the workers and avoid prolonged exposure to the pungent and humid environment. (4) The device can overcome the problem that the construction quality of anti-rust paint cannot be guaranteed when workers apply it in a narrow space. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the track-type device for spraying anti-rust paint on the weld seams of large-diameter jacking pipes in the working well, as described in this utility model embodiment.

[0011] In the diagram, 1 is the pipe jacking system; 2 is the annular double track; 3 is the connecting rod; 4 is the working shaft wall; 5 is the automatic paint spraying machine; 6 is the track rod; and 7 is the H-shaped track wheel. Detailed Implementation

[0012] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0013] Example: Figure 1 The above describes a track-type device suitable for spraying anti-rust paint on the weld seams of large-diameter jacking pipes in working wells. It includes a ring-shaped double track 2 set around the jacking pipe 1. The ring-shaped double track 2 is fixedly connected to the working well wall 4 by several evenly arranged connecting rods 3. Both the ring-shaped double track 2 and the connecting rods 3 are made of round steel to ensure that the automatic paint spraying machine 5 runs smoothly and stably.

[0014] Furthermore, an automatic paint sprayer 5 is installed on the inner side of the annular double track 2. The automatic paint sprayer 5 can move along the annular double track 2 and is fixedly connected to two track rods 6. Both ends of the track rods 6 are rolledly connected to the annular double track 2 through H-shaped track wheels 7. The distance between the paint spray nozzle of the automatic paint sprayer 5 and the surface of the pipe weld is maintained at 20-30cm.

[0015] In practical application of this embodiment, the automatic spray painting machine 5 is remotely controlled to uniformly spray anti-rust paint around the jacking pipe 1 on the annular double track 2. The pressure is kept stable at 0.2-0.3MPa and the spraying distance remains constant. This ensures that the anti-rust paint film and width at the weld of the jacking pipe 1 are effectively guaranteed, and also allows the workers to avoid the pungent and humid working conditions.

[0016] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent solutions made using the contents of this utility model specification, whether directly or indirectly applied to other related technical fields, are also within the patent protection scope of this utility model.
