Description

Technical area

[0001] The present utility model relates to the technical field of protective pipe tunnel construction, in particular to a pipe transport and installation vehicle suitable for a protective pipe tunnel. State of the art

[0002] In the engineering field of conduit tunnel construction, due to the emphasis on cost-effectiveness and maximum utilization of construction space, various types of large-diameter pipes and large-caliber corridor pipes (pipe diameter greater than or equal to 1.2 m) and other components are often arranged in the newly constructed pipe tunnel lines. The interior of the pipe tunnel is very narrow and confined, and the working space is insufficient. When the pipes are to be transported and laid, such as water pipes, manual transport is difficult due to the narrow interior of the pipe tunnel and the great stress caused by the large weight and volume of the pipes. The usual transportation method is to pull the pipes to the installation position with a winch.However, since the concrete pipe piers are provided at predetermined installation positions along the pipes' axial direction, after reaching the pipe piers, the pipes still need to be lifted and transferred to the piers using manual labor and lifting hooks. Then, steel beams are configured to temporarily fix and support the pipes for coupling and welding. Furthermore, the pipeline route often has certain curvatures and inclinations, resulting in cumbersome work processes, high safety risks, high labor costs, and low efficiency in transportation and installation, affecting the construction period. Summary of the utility model

[0003] The purpose of the present utility model is to provide a pipe transport and installation vehicle suitable for a protective pipe tunnel to overcome the technical problems of high labor requirement, low construction efficiency and high safety risk caused by the need to move a pipe to a pipe pier by means of manual labor and a fixed chain hoist during the construction of an existing pipe tunnel, and to use a steel girder for temporary support.

[0004] In a first aspect, the present utility model provides a pipe transport and installation vehicle suitable for a protective pipe tunnel and comprising: a vehicle body; Wheels rotatably connected to the vehicle body, the number of wheels being at least two; a drive device is connected to at least one of the wheels, the drive device being suitable for driving the rotation of the wheel; a steering device is connected to at least one of the wheels, the steering device being suitable for steering the wheel; a containment structure, the containment structure being adapted to connect and receive a pipe to be arranged, and the containment structure being connected to the vehicle body via a telescopic device; wherein extension of the telescopic device can drive the containment structure to rise to a height higher than the upper surface of the pipe pillar; and shortening of the telescopic device can cause the containment structure to fall to a height lower than the upper surface of the pipe pillar.

[0005] When transporting the pipe to be placed by the pipe transport and installation vehicle suitable for the protective pipe tunnel, the pipe to be placed is first placed on a containment structure. Then, a driving device and a steering device are operated so that the vehicle body supports the pipe to be placed, performing actions such as moving forward and backward, turning, and climbing in the pipe tunnel until it reaches the vicinity of the pipe pier. Then, the telescopic device is extended to lift the containment structure together with the pipe to be placed to a height exceeding the top of the pipe pier. The driving device and the steering device are operated to move the vehicle body between two adjacent pipe piers, and then the pipe to be placed is moved over the pipe piers, ensuring that the pipe to be placed does not collide with the pipe piers.The telescopic device is lowered and the position of the vehicle body is precisely adjusted, that is, the pipe to be arranged can reach a predetermined installation position, the transportation and positioning of the pipe to be arranged can be completed, and the subsequent connection work can be carried out.

[0006] From the above, it can be seen that the transport of the pipe to be arranged by the vehicle body, which can move back and forth and rotate according to the present solution, is better able to adapt to the internal environment of the pipe tunnel, which is narrow and has curvature and inclination, compared to the prior art using the traction force of the winch. At the same time, the solution also provides a liftable limiting structure on the vehicle body, which can automatically achieve the process of lifting the pipe to be arranged above the pipe pier without the aid of labor, lifting hooks, and steel beams. Thus, this solution has the effects of simple operation, low safety risk coefficient, low labor consumption, and high construction efficiency.

[0007] Preferably, the restricting structure consists of an arranging base and at least two restricting claws; the arranging base is connected to the telescopic device; the restricting claws are spaced apart from each other on the arranging base; and the distance between two adjacent restricting claws can be adjusted according to the size of the pipe to be arranged in order to clamp the pipe to be arranged.

[0008] This solution recommends a specific design of the limiting structure, and the pipes to be arranged are connected by clamps. Compared with other methods, such as creating a profiled groove or a profiled through hole, the shape of the limiting claw does not need to match the pipe to be arranged, but can be attached to the outer wall of the pipe to be arranged, thus reducing the manufacturing difficulty and cost of the limiting claw.

[0009] Preferably, at least one of the limiting claws is connected to the arrangement base via a waist-shaped hole.

[0010] This solution recommends a structure that can adjust the distance between two adjacent limit claws. The waist-shaped hole is simple in structure and reliable in operation, which can reduce the manufacturing difficulty and cost of this solution.

[0011] Preferably, the limiting claw is detachably connected to the arrangement base.

[0012] With this solution, the limit claws can be easily replaced to adapt to different sizes or shapes of the pipes to be arranged, which improves the universality of this solution. At the same time, it is easy to replace the damaged limit claw, improving the maintainability of this solution.

[0013] Preferably, the steering device is connected to all wheels.

[0014] This solution makes it possible to further improve the steerability of the vehicle body, allowing the vehicle body to be flexibly moved in several directions, which facilitates the movement between two adjacent pipe pillars for the insertion of a pipe to be arranged.

[0015] Preferably, the telescopic device comprises a hydraulic rod, wherein one end of the hydraulic rod is connected to the boundary structure and the other end of the hydraulic rod is connected to the vehicle body.

[0016] This solution recommends one of the concrete structure forms of telescopic devices that has the advantages of strong bearing capacity and smooth operation, and can be applied for the transportation of heavy pipes to be arranged.

[0017] Preferably, it further comprises a gear mechanism, wherein an input end of the gear mechanism is connected to the driving device; an output end of the gear mechanism is connected to at least two of the wheels; and the driving device can drive the corresponding wheels through the gear mechanism for synchronous rotation.

[0018] In this solution, the wheels are connected to each other by a gear mechanism, so that the corresponding wheels can rotate synchronously and the operation of this solution is smoother and more controllable.

[0019] Preferably, it further comprises an electronic control module communicatively connected to the drive device, the steering device, and the telescopic device; and the electronic control module is configured to control the starting and stopping of the drive device, the steering device, and the telescopic device.

[0020] By controlling the drive device, the steering device and the telescopic device through the electronic control module, the fully automatic transport of the pipe to be arranged can be realized, which further reduces the personnel effort and the safety risk of the solution.

[0021] Preferably, a one-sided steering range of the steering device is greater than or equal to 90°.

[0022] This solution allows the steering device to be steered by at least 90° to one side, ie the rolling direction of the wheel after steering deviates by 90° from the rolling direction before steering, so that the wheel can be switched between rolling axially along the tunnel axis and rolling transversely along the tunnel, which facilitates driving between two adjacent pipe pillars for the insertion of the pipe to be arranged.

[0023] The wheels are preferably solid rubber wheels.

[0024] This solution ensures that the wheels have sufficient grip to prevent them from slipping in the pipe tunnel with a steep gradient, thus ensuring transport safety and reducing the possibility of serious accidents.

[0025] The utility model has the following advantages over the prior art: The present utility model provides a pipe transport and installation vehicle suitable for a protective pipe tunnel. When the pipe to be installed is transported via a vehicle body capable of forward and backward movement and rotation, it is better able to adapt to the internal environment of the pipe tunnel, which is narrow and has curves and inclines, compared to the prior art that uses the traction of a winch.At the same time, the solution also provides a liftable limiting structure on the vehicle body, which can automatically achieve the process of lifting the pipe to be arranged above the pipe pier without the help of manpower, lifting hooks and steel beams, so this solution has the effect of simple operation, low safety risk coefficient, low labor consumption and high construction efficiency.
