Description

Technical Field

[0001] This utility model relates to the field of highway tunnel construction technology, specifically a maintenance device that can spray moisture onto the corners and edges of a highway tunnel. Background Technology

[0002] During highway tunnel construction, concrete curing plays a crucial role in ensuring the durability and stability of the tunnel structure. In particular, the curing quality of the concrete at sharp corners such as steps and the arc transition area connecting the invert arch and the sidewall directly affects the service life and safety of the entire tunnel.

[0003] Currently, although some equipment exists for highway tunnel maintenance, it presents numerous problems when performing wet spraying on sharp, angular areas. Traditional wet spraying equipment often has a fixed spray range, making it difficult to flexibly adjust the spray direction and position. This makes it challenging to precisely wet protruding or recessed areas of different shapes and angles, easily leading to missed areas. This results in the concrete surface of these areas drying out, affecting their strength development and durability, potentially causing structural damage to the tunnel, increasing later maintenance costs, and even impacting the normal operation and safety of the tunnel. Therefore, we propose a maintenance device that can wet the sharp, angular areas inside highway tunnels. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a maintenance device for spraying moisture onto the corners of highway tunnels, comprising a water tank 1, wherein a water pump is installed inside the water tank 1, and a battery for powering the water pump is installed inside the water tank 1. The battery can be a commonly used lead-acid battery or a lithium-ion battery, etc. The water pump can also be powered by an external power source or a vehicle power source via cables, etc.

[0023] The water pump's outlet is connected to the spray pipe 4, which extends through the side surface of the water tank 1 and connects to the first gooseneck pipe 44. The first gooseneck pipe 44 is connected to the outlet pipe 46, and a second gooseneck pipe 48 is installed on each side of the outlet pipe 46. Both the end of the second gooseneck pipe 48 and the end of the outlet pipe 46 are equipped with nozzles 47.

This effectively avoids omissions in curing, thereby improving the curing quality of the entire highway tunnel concrete structure and ensuring the durability and stability of the tunnel structure. Meanwhile, the multi-nozzle design allows for simultaneous spraying and wetting of different parts of the edges and corners during a single maintenance operation. This enables the spraying of edges and corners or grooves to be completed in one go, improving maintenance efficiency, shortening the maintenance cycle, and helping to accelerate the construction progress of highway tunnels, allowing them to be put into use sooner.

[0024] The shapes, angles, and positions of the corners inside highway tunnels vary. The equipment, with its adjustable gooseneck design, can be adapted to different construction environments and corner shapes. Whether it is a protruding step edge or a recessed arc transition area, it can achieve effective spraying and curing, has good adaptability, and can be widely used in the maintenance of various highway tunnels.

[0025] In a preferred embodiment, wheel frames 10 are provided at the four corners of the lower surface of the water tank 1, and rollers 11 are rotatably mounted on the wheel frames 10. A push handle 8 is provided on the upper side surface of the water tank 1. The push handle 8 and the rollers 11 enable the entire maintenance equipment to move conveniently and quickly within the highway tunnel, facilitating rapid spraying and maintenance of sharp corners and other areas along the length of the highway tunnel.

[0026] In a further preferred technical solution, a foot brake 12 corresponding to the roller 11 is installed on the wheel frame 10 on the side of the water tank 1 near the pusher 8, which facilitates parking and fixing the water tank 1 at any time, prevents slippage, ensures safe and stable maintenance operations, and improves work accuracy.

[0027] In a preferred embodiment, a control panel 9 is installed on the pusher 8. The control panel 9 is equipped with a control switch corresponding to the water pump. The control switch is electrically connected to a battery or an external power source, and is also electrically connected to the water pump, for controlling the on / off state and speed of the water pump.

[0028] Optionally, a water level sensor can be installed in the water tank 1, and a display screen corresponding to the water level sensor can be installed on the control panel 9, so that staff can check the remaining water at any time and replenish the maintenance water in a timely manner.

[0029] In a preferred embodiment, the upper surface of the water tank 1 is provided with a water inlet 2 for adding water to the water tank 1. A sealing cap 3 is provided at the water inlet 2 to prevent impurities from entering, ensure water quality, and extend the service life of the equipment.

[0030] The water pumps, batteries, and water level sensors used in this application are all commonly used electronic components in the prior art. Their specific structures, working principles, control methods, and circuit connections are all well-known technologies and will not be described in detail here.

[0031] An optional technical solution is that the spray pipe 4 includes a fixed pipe 41, a corrugated pipe 42, and a main pipe 43. One end of the fixed pipe 41 is connected to the outlet of the water pump, and the other end extends out of the upper surface of the water tank 1 and is connected to the main pipe 43 through the corrugated pipe 42. The first gooseneck pipe 44 is connected to the main pipe 43. The fixed pipe 41, the main pipe 43, and the outlet pipe 46 are all rigid pipes. The corrugated pipe 42 is a telescopic and bendable pipe. The position of the main pipe 43 can be adjusted by telescopically and bending the corrugated pipe 42, and the position and angle of the fixed pipe 41 and the second gooseneck pipe 48 can be further adjusted, thereby improving the adaptability of the equipment to spraying and maintaining the corners at different positions and heights in the highway tunnel.

[0032] Optionally, the end of the first gooseneck tube 44 is connected to the outlet tube 46 via a rotating tube 45. The rotating tube 45 is fixedly connected to the first gooseneck tube 44, while the outlet tube 46 is rotatably connected to the rotating tube 45. A rotation seal is provided between the outlet tube 46 and the rotating tube 45 to prevent leakage. The rotating tube 45, in conjunction with the first gooseneck tube 44 and the second gooseneck tube 48, can expand the adjustment range of the nozzle 47, further improving the versatility of the equipment.

[0033] In a preferred embodiment, a connecting rod 5 is provided on the side surface of the water tank 1. A ball groove is provided at the end of the connecting rod 5, and a first universal ball 6 is provided in the ball groove. A first clip 7 is fixedly provided on the outer surface of the first universal ball 6. The first clip 7 is snapped onto the outside of the main pipe 43, which can fix the main pipe 43 part to the side of the water tank 1. At the same time, by adjusting the angle of the first universal ball 6, the approximate angle of the nozzle 47 is adjusted. Then, by adjusting the second gooseneck tube 48, the spraying angle of the nozzle 47 is further adjusted. Thus, while the water tank 1 is being moved, the nozzle 47 can be used to spray and maintain the edges or recessed parts inside the highway tunnel, making the operation more convenient.

[0034] In a further preferred embodiment, a groove is provided at the edge of the upper surface of the water tank 1, a sliding cylinder 13 is slidably disposed in the groove, a sliding rod 14 is slidably disposed inside the sliding cylinder 13, a fixing post 15 is fixedly disposed at the top of the sliding rod 14, a ball groove is provided at the end of the fixing post 15, a second universal ball 16 is disposed in the ball groove, and a second clamp 17 corresponding to the main pipe 43 is fixedly disposed on the outer surface of the second universal ball 16. When it is necessary to spray wet maintenance on the high corners or recessed areas of the highway tunnel, the main pipe 43 can be removed from the first clamp 7, its end can be placed in the second clamp 17, and then the height of the sliding rod 14 and the sliding cylinder 13 can be adjusted to a suitable position so that the nozzle 47 is aimed at the high spraying area. Then, the spraying angle can be finely adjusted by the second universal ball 16, so that the nozzle 47 can spray wet maintenance on the high corners or recessed areas of the highway tunnel.

[0035] The chute and sliding cylinder 13, and the sliding cylinder 13 and sliding rod 14 can be fixed together by their mutual friction to ensure the stability of the spraying process. Alternatively, fastening bolts or a quick adjustment device similar to that used for adjusting and fixing bicycle seats can be installed on the sliding cylinder 13 to fix the position of the sliding rod 14; while fastening bolts corresponding to the fixed cylinder 13 are installed on the water tank 1 to fix the sliding cylinder 13.

[0036] Both the first clip 7 and the second clip 17 include two arc-shaped blocks with a certain degree of elasticity. The main tube 43 can be clipped between the two arc-shaped blocks to fix the main tube 43.

[0037] Both the first universal ball 6 and the second universal ball 16 are made of rubber balls, and there is a certain friction between them and the ball groove. After the main tube 43 is fixed on the clamp, when no external force is applied, the first universal ball 6 and the second universal ball 16 are fixed by friction and will not rotate, thus ensuring the stability of the spray curing process.

[0038] The parts not disclosed in this utility model are all prior art, and their specific structures, materials, and working principles will not be described in detail. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
