Description

Technical Field

[0001] This utility model relates to the field of tunnel trolley technology, specifically a multi-functional tunnel grinding and cleaning trolley. Background Technology

[0002] Currently, in tunnel cleaning and maintenance operations, traditional equipment is mostly simple frame structures temporarily welded by construction units according to on-site needs. Such equipment has many technical defects and safety hazards, and can no longer meet the requirements of high efficiency, safety, and standardization in modern tunnel maintenance. The disadvantages are as follows: Low operational efficiency: It relies on manual labor to stand on a simple frame and use hand tools for cleaning and polishing. The speed of manual operation is limited (the average cleaning efficiency is only 3-5m / h), and continuous automated operation cannot be achieved; for tunnels with a length of more than 1,000 meters, the maintenance cycle can last for several months. The work intensity and safety risks are prominent: workers need to be on a high-altitude work platform (3-5m high) for a long time, repeatedly performing bending and raising movements, which is extremely labor-intensive; the simple frame has no stable protective structure (such as no anti-collision and anti-fall design), which is easy to collide with the tunnel wall or cause people to fall; the humid and dusty environment in the tunnel can easily cause short circuits in electrical equipment. Poor equipment adaptability: Traditional frames are mostly fixed structures that cannot be folded or disassembled. They need to be hoisted as a whole during transportation, making it difficult to pass through narrow tunnel entrances (such as tunnels with a diameter ≤5m); the platform size is fixed, and the working range cannot be adjusted according to the inner diameter of the tunnel. There are blind spots for cleaning and maintenance in tunnels with non-circular cross sections. The maintenance effect is unstable: the manual operation force and path are inconsistent, and the cleanliness of the tunnel wall is uneven (local residual algae and silt thickness exceeds 5mm); there is no accurate distance measurement function, which can easily damage the tunnel lining structure. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a multi-functional tunnel grinding and cleaning trolley, which realizes all-round and continuous grinding and cleaning of the tunnel inner wall, effectively integrates multiple functions such as grinding, high-pressure flushing, and distance monitoring, and significantly improves the overall efficiency of the equipment; it solves the problems of low efficiency, high labor intensity, poor adaptability and prominent safety hazards of traditional tunnel maintenance equipment, and can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional tunnel grinding and cleaning trolley, including a gantry, which travels inside the tunnel. The end of the gantry is provided with an arc-shaped track that matches the tunnel cross-section. A cleaning trolley is slidably fitted onto the arc-shaped track. The cleaning trolley is driven by a drive system and travels along the arc-shaped track. The gantry is provided with a high-pressure cleaning assembly that provides water to the cleaning trolley. The cleaning trolley includes a fixed base, with T-shaped wheels adapted to the arc-shaped track at the bottom. The fixed base is connected to a trolley bracket via a screw jack. A roller brush is rotatably connected to the upper part of the trolley bracket via bearing seats. One of the bearing seats is equipped with a motor that drives the roller brush to rotate. The trolley bracket is also connected to an arc-shaped housing, which is located below the roller brush. Several high-pressure nozzles are provided at both ends of the arc-shaped housing on both sides corresponding to the rolling direction of the roller brush.

[0005] Preferably, the high-pressure cleaning assembly includes a water tank and a high-pressure cleaner. The high-pressure cleaner is connected to the water tank through a water inlet pipe and to a high-pressure nozzle through a high-pressure water pipe.

[0006] Preferably, the end of the gantry is also provided with a pipeline swing rod. One end of the pipeline swing rod is rotatably connected to the gantry through a bearing, and the other end of the pipeline swing rod is connected to the fixed seat of the cleaning trolley through a chain. The high-pressure water pipe is fixed to the pipeline swing rod by a pipe clamp.

[0007] Preferably, the drive system includes a drive motor and a chain. The chain is arranged along an arc-shaped track and connected to a fixed seat of the cleaning trolley.

[0008] Preferably, the trolley bracket is equipped with a laser ranging sensor for monitoring the distance between the roller brush and the tunnel wall.

[0009] Preferably, limit switches are provided at both ends of the arc-shaped track.

[0010] Preferably, the lower part of the trolley bracket is also provided with a guide post, and the fixing seat is provided with a guide hole adapted to the guide post.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: By setting an arc-shaped track on the gantry that matches the tunnel cross-section, and sliding a cleaning trolley on the track, it achieves all-round and continuous grinding and cleaning of the tunnel inner wall, effectively integrating multiple functions such as grinding, high-pressure washing, and distance monitoring, significantly improving the overall efficiency of the equipment; the cleaning trolley is equipped with a rotating roller brush and an arc-shaped shell located below it, with multiple high-pressure nozzles at both ends of the shell, which can perform high-pressure water washing in the front and back directions while the roller brush is grinding, which not only improves cleaning efficiency, but also avoids dust flying, improves the working environment, and effectively prevents secondary adhesion of dirt; it solves the problems of low efficiency, high labor intensity, poor adaptability, and prominent safety hazards of traditional tunnel maintenance equipment.

[0014] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0015] Please see Figure 1-6 The present invention provides the following technical solution: Example 1: A multi-functional grinding and cleaning trolley for tunnels includes a gantry 1, which travels inside the tunnel. The lower part of the gantry 1 is equipped with four wheels 1.1. The end of the gantry 1 is equipped with an arc-shaped track 3 that matches the tunnel cross-section. A cleaning trolley 2 is slidably fitted onto the arc-shaped track 3. The cleaning trolley 2 is driven by a drive system 6 and travels along the arc-shaped track 3. The gantry 1 is equipped with a high-pressure cleaning assembly 4 that provides water to the cleaning trolley 2. The cleaning trolley 2 includes a fixed base 2.6. The lower part of the fixed base 2.6 is equipped with a T-shaped wheel 2.4 that is adapted to the arc-shaped track 3. The fixed base 2.6 is connected to the trolley bracket 2.7 through a screw jack 2.5. The upper part of the trolley bracket 2.7 is rotatably connected to a roller brush 2.1 through a bearing seat. One of the bearing seats is equipped with a motor 2.2 that drives the roller brush 2.1 to rotate. The trolley bracket 2.7 is also connected to an arc-shaped housing 2.8, which is located below the roller brush 2.1. Both ends of the arc-shaped housing 2.8 are equipped with several high-pressure nozzles 2.9 on both sides corresponding to the rolling direction of the roller brush 2.1. The motor 2.2 drives the roller brush 2.1 to rotate to achieve grinding of the tunnel wall, while the high-pressure nozzles 2.9 perform high-pressure water washing. The four traveling wheels 1.1 at the bottom of the gantry 1 adopt a combination design of "4-wheel drive + 4-wheel electric steering", which can adapt to tunnels with a longitudinal slope of 5%, turns and uneven ground conditions. The gantry 1 travels in the tunnel and drives the cleaning trolley 2 to reciprocate along the arc track 3 through the drive system 6, thereby realizing automated, all-round and continuous grinding and cleaning operations on the tunnel wall. It integrates multiple functions such as grinding, high-pressure washing and distance monitoring. Specifically, the high-pressure cleaning component 4 includes a water tank 4.1 and a high-pressure cleaner 4.3. The high-pressure cleaner 4.3 is connected to the water tank 4.1 through a water inlet pipe 4.2 and to the high-pressure nozzle 2.9 through a high-pressure water pipe 4.4. The high-pressure cleaner 4.3 draws water from the water tank 4.1 through the water inlet pipe 4.2 and pumps it to the high-pressure nozzle 2.9 through the high-pressure water pipe 4.4. Furthermore, the end of the gantry 1 is also provided with a pipeline swing rod 5. One end of the pipeline swing rod 5 is rotatably connected to the gantry 1 through a bearing, and the other end of the pipeline swing rod 5 is connected to the fixed seat 2.6 of the cleaning trolley 2 through a chain. The high-pressure water pipe 4.4 is fixed to the pipeline swing rod 5 through a pipe clamp. By setting the pipeline swing rod 5 and connecting the cleaning trolley 2 with a chain, the high-pressure water pipe 4.4 swings synchronously with the movement of the trolley, avoiding pipeline entanglement, pulling or wear, ensuring a stable supply of high-pressure water, and improving the reliability and safety of system operation. Specifically, the drive system 6 includes a drive motor and a chain. The chain is arranged along the arc-shaped track 3 and is connected to the fixed seat 2.6 of the cleaning trolley 2. The drive motor is mounted on the gantry 1, and the output end of the drive motor is connected to a sprocket. The sprocket meshes with the chain. The drive system 6 adopts a motor-chain transmission method to control the cleaning trolley 2 to move automatically back and forth along the arc-shaped track 3.

[0016] Example 2: Unlike Example 1, the trolley bracket 2.7 is equipped with a laser rangefinder sensor for monitoring the distance between the roller brush 2.1 and the tunnel wall. The laser rangefinder sensor provides real-time position information. The distance between the roller brush 2.1 and the tunnel wall is adjusted by the screw lift 2.5 to achieve precise fit and adapt to different curvatures and uneven tunnel cross sections.

[0017] Example 3: Unlike Example 1, limit switches are provided at both ends of the arc track 3 to prevent the cleaning trolley 2 from overtraveling and detaching from the arc track 3, thus ensuring safe operation.

[0018] Example 4: The lower part of the trolley bracket 2.7 is also provided with a guide post 2.3, and the fixed seat 2.6 is provided with a guide hole that matches the guide post 2.3 to ensure the accuracy of the movement of the trolley bracket 2.7 under the action of the screw jack 2.5.

[0019] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents in the content of this utility model.
