Description

Technical Field

[0001] The utility model relates to the technical field of shield pipe gallery construction, and particularly relates to a pipeline transportation and installation vehicle applicable to shield pipe galleries. Background Technique

[0002] In the technical field of shield pipe gallery construction, due to the emphasis on economy and the maximum utilization rate of construction space, various comprehensive pipelines, large-diameter pipelines entering the gallery (the pipeline diameter is greater than or equal to 1.2 m), and other components are often arranged in the newly built pipe gallery line. The internal space of the pipe gallery is extremely narrow and airtight, and the construction operation surface is insufficient. When transporting and installing pipelines, such as water conveyance pipelines, due to the narrow internal space of the pipe gallery and the large self-weight and volume space occupation of the pipelines, it is difficult to carry out manual transportation. The common transportation and installation method is to use a winch to tow the pipeline to the installation position. However, since concrete pipe piers are arranged at intervals along the axial direction of the pipeline at the predetermined installation position of the pipeline, after the pipeline reaches the pipe pier, it is still necessary to use manual labor and a hoist hook to lift and translate the pipeline onto the pipe pier, and then use a steel support to temporarily fix and support the pipeline, so as to carry out alignment and welding. In addition, the pipe gallery line often has a certain curvature and slope, resulting in a cumbersome operation process, a high safety risk coefficient, a large consumption of manual labor, a low transportation and installation efficiency, and an impact on the construction period in this construction method. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the technical problems in the existing pipe gallery construction that it is necessary to use manual labor and a hoist hook to move the pipeline onto the pipe pier and use a steel support for temporary support, resulting in a large consumption of manpower, low construction efficiency, and high safety risks, and to provide a pipeline transportation and installation vehicle applicable to shield pipe galleries.

[0004] In the first aspect, the utility model provides a pipeline transportation and installation vehicle applicable to shield pipe galleries, comprising:

[0005] A vehicle body;

[0006] Wheels, the wheels are rotatably connected to the vehicle body, and the number of wheels is at least two; at least one wheel is connected with a driving device for driving the wheel to rotate; at least one wheel is connected with a steering device for driving the wheel to turn;

[0007] A limiting structure for connecting the pipeline to be installed, the limiting structure is connected to the vehicle body through a telescopic device; when the telescopic device extends, it can drive the limiting structure to rise to a height higher than the upper surface of the pipe pier, and when the telescopic device shortens, it can drive the limiting structure to drop to a height lower than the upper surface of the pipe pier.

[0008] When the pipe transportation and installation vehicle for shield pipe galleries in this solution transports the pipe to be installed, first place the pipe to be installed on the limiting structure, and then operate the driving device and the steering device to make the vehicle body carry the pipe to be installed and perform actions such as advancing, retreating, turning, and climbing inside the pipe gallery until it reaches near the pipe pier; then extend the telescopic device to lift the limiting structure together with the pipe to be installed to a height exceeding the upper surface of the pipe pier; at this time, operate the driving device and the steering device again to move the vehicle body between two adjacent pipe piers, and then the pipe to be installed can be moved above the pipe pier, and the pipe to be installed will not interfere with the pipe pier; lower the telescopic device and finely adjust the position of the vehicle body, and the pipe to be installed can reach the predetermined installation position, completing the transportation and positioning of the pipe to be installed, and then subsequent connection work can be carried out.

[0009] As can be seen from the above, this solution transports the pipe to be installed through a vehicle body that can advance and retreat and turn, which is more adaptable to the narrow space and the internal environment of the pipe gallery with curvature and slope compared with the existing technology that uses a winch to tow; at the same time, this solution also sets a liftable limiting structure on the vehicle body, which can automatically realize the operation of lifting the pipe to be installed above the pipe pier without the help of manpower, hoist hooks and steel brackets, so that this solution has the effects of simple operation, low safety risk coefficient, small manpower consumption and high construction efficiency.

[0010] Preferably, the limiting structure includes an installation base and at least two limiting claws; the installation base is connected to the telescopic device; the limiting claws are distributed at intervals on the installation base, and the distance between two adjacent limiting claws is adjustable to adapt to the size of the pipe to be installed, so as to clamp the pipe to be installed.

[0011] This solution recommends a specific structural form of the limiting structure, which connects the pipe to be installed by clamping. Compared with other methods, such as setting a profiling groove or a profiling through hole, the shape of the limiting claw does not need to match the pipe to be installed, but can abut against the outer wall of the pipe to be installed, so as to reduce the manufacturing difficulty and manufacturing cost of the limiting claw.

[0012] Preferably, at least one limiting claw is connected to the installation base through a kidney-shaped hole.

[0013] This solution recommends a structure that can adjust the distance between two adjacent limiting claws. The kidney-shaped hole structure is simple and reliable in operation, and can reduce the manufacturing difficulty and manufacturing cost of this solution.

[0014] Preferably, the limiting claw is detachably connected to the installation base.

[0015] This solution can conveniently replace the limiting claw to adapt to pipes to be installed with different size specifications or different shapes, so as to improve the versatility of this solution; at the same time, it can also conveniently replace the damaged limiting claw, so as to improve the maintainability of this solution.

[0016] Preferably, all wheels are connected with steering devices.

[0017] This solution can further enhance the steering ability of the vehicle body, enabling the vehicle body to translate flexibly in multiple directions, thereby making it easier to drive into the space between two adjacent pipe supports to place the pipeline to be installed.

[0018] Preferably, the telescopic device includes a hydraulic rod. One end of the hydraulic rod is connected to the limit structure, and the other end is connected to the vehicle body.

[0019] This solution recommends a specific structural form of the telescopic device, which has the advantages of strong load-bearing capacity and stable operation, and can be applied to transporting pipelines to be installed with relatively large weights.

[0020] Preferably, it further includes a transmission mechanism. The input end of the transmission mechanism is connected to the driving device, and the output end is connected to at least two wheels. The driving device can drive the corresponding wheels to rotate synchronously through the transmission mechanism.

[0021] This solution connects the wheels through the transmission mechanism, enabling the corresponding wheels to rotate synchronously, thereby making the operation of this solution more stable and controllable.

[0022] Preferably, it further includes an electronic control module. The electronic control module is communicatively connected to the driving device, the steering device, and the telescopic device, and is used to control the start and stop of the driving device, the steering device, and the telescopic device.

[0023] This solution controls the driving device, the steering device, and the telescopic device through the electronic control module, enabling fully automated transportation of the pipeline to be installed, thereby further reducing the labor consumption and safety risks of this solution.

[0024] Preferably, the unilateral steering range of the steering device is greater than or equal to 90°.

[0025] This solution enables the steering device to turn at least 90° to one side, that is, the rolling direction of the wheel after steering is 90° different from the rolling direction before steering, enabling the wheel to switch between rolling along the axial direction of the tunnel and rolling along the transverse direction of the tunnel, thereby making it easier to drive into the space between two adjacent pipe supports to place the pipeline to be installed.

[0026] Preferably, the wheels are solid rubber-coated wheels.

[0027] This solution can ensure that the wheels obtain sufficient grip, preventing the wheels from slipping in places with a relatively large slope in the pipe gallery, thereby ensuring transportation safety and reducing the possibility of major risk accidents.

[0028] Compared with the prior art, the beneficial effects of the present utility model:

[0029] The utility model provides a pipeline transportation and installation vehicle applicable to a shield pipe gallery, which transports the pipeline to be installed through a vehicle body that can move forward and backward and turn. Compared with the prior art using a winch for traction, it can better adapt to the internal environment of a pipe gallery with narrow space, curvature and slope. At the same time, the scheme also sets a liftable limit structure on the vehicle body, which can automatically lift the pipeline to be installed above the pipe pier without the help of manpower, a hoist hook and a steel support, so that the scheme has the effects of simple operation, low safety risk coefficient, small manpower consumption and high construction efficiency.
