Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel pipe transportation in water conservancy and hydropower engineering, and particularly relates to a steel pipe transportation method and a steel pipe transportation turnover device. BACKGROUND

[0002] In a water conservancy and hydropower engineering project, a water conveying pipeline is usually made of a steel pipe or a steel lining, and is located inside a tunnel. For some pumped storage power stations, the size of the steel pipe is relatively small. For such small-sized steel pipes, a single steel pipe section is usually processed outside the tunnel during construction, and then transported into the tunnel in the form of a single steel pipe section and subjected to subsequent construction operations.

[0003] In the existing mode, in order to ensure the safety of the transportation process, a flat car, a truck or other transportation vehicles are generally used for pipe section transportation. The steel pipe section is generally placed in a vertical state with the pipe opening upward on the transportation vehicle to ensure the stability of the transportation. The single steel pipe section is transported from outside the tunnel into the tunnel, and when the pipe section is installed in the horizontal tunnel, the pipe opening must be in a horizontal state. Therefore, when the pipe section enters the tunnel for installation, it must be hoisted and turned over in the air to make the pipe opening horizontal. For example, after reaching the intersection position of the traffic branch tunnel and the main tunnel, the steel pipe section is unloaded from the vehicle through the hoisting point previously set on the top of the tunnel, and is turned over by 90 degrees in the air to make the pipe opening horizontal, and then is transferred to a dedicated transportation trolley for subsequent transportation and installation of the steel pipe section. That is, the existing construction method must set a hoisting point or hoisting equipment on the top of the tunnel to perform the turnover construction operation. For example, the chamber internal pressure steel pipe section turnover device disclosed in the Chinese Utility Model Patent with the publication number CN202542770U increases the equipment investment and construction cost. The turnover operation in the air also brings certain safety operation risk and the possibility of safety accidents.

[0004] The Chinese Invention Patent with the publication number CN114043390B discloses a pipe section supporting and turning over equipment, which is used for processing the stiffening ring of the pipe section. Although the pipe section can be turned over between the horizontal direction and the vertical direction, the pipe section cannot be transported, so that other equipment is needed to transport the vertical pipe section to the designated installation position, then the pipe section is turned over by the pipe section supporting and turning over equipment, and then the pipe section is installed, so that the construction process is relatively complex, the equipment investment and construction cost are increased, and it is difficult to ensure that the stability of the turnover and transportation processes can be met at the same time based on the prior art. SUMMARY

In step S4, the hydraulic cylinder arranged above the vehicle body overturns the steel pipe section from vertical to horizontal, and places the steel pipe section on the special transportation equipment in the main tunnel, and then transports the horizontal steel pipe section in the main tunnel through the special transportation equipment for installation.

[0047] The steel pipe transportation and overturning device in the embodiment 1 can be used to transfer and overturn the pressure steel pipe section outside or inside the tunnel, and has two use methods, that is, one is used as a transportation vehicle alone, and the other is used as a trailer combined with a general tractor head.

[0048] Method 1: used alone When the steel pipe transportation and overturning device is used alone, a driving motor 21 needs to be installed on the wheel set 2, and the steel pipe transportation and overturning device is driven to walk by the driving motor 21, which is especially suitable for short-line transportation of the pipe section.

[0049] The steel pipe section 8 is hoisted and placed on the lifting support 3 of the steel pipe transport and turnover device in the initial transfer position, as shown in the figure, with the pipe opening side close to the first plate 41 of the pipe section support 4. The steel pipe section 8 is transported to the intersection position of the traffic branch hole and the main tunnel by the steel pipe transport and turnover device, the auxiliary support foot 6 is extended and supported on the ground to increase the stability of the steel pipe transport and turnover device. The lifting support 3 is lifted by the hydraulic cylinder 5 on the vehicle body 1, and is rotated around the side hinge point of the vehicle body 1, so that the pipe section is turned over by 90°. Two groups of special transport devices are pre-installed in the main tunnel, as shown in the figure, and the pipe section can be placed on the special transport device after being turned over by 90°, without relying on the lifting point at the top to complete the construction. The special transport device can be a multifunctional transport trolley which can walk along the transport track 91, which is a prior art. After the turnover is completed, the special transport device transports the steel pipe section into the next construction stage, at this time the auxiliary support foot 6 of the steel pipe transport and turnover device is retracted, and the steel pipe transport and turnover device is walked to the initial position for the transfer of the next steel pipe section.

This mode can be used for short-line or long-line transportation, but it is especially suitable for long-line transportation of pipe sections.

[0050] First, the steel pipe transport and turnover device is connected with the towing vehicle head through the bottom towing pin 7, and the steel pipe section 8 is hoisted and placed on the lifting support of the steel pipe transport and turnover device in the initial transfer position, as shown in the figure, with the pipe opening side close to the pipe section support. The steel pipe section is transported to the intersection position of the traffic branch hole and the main tunnel by the steel pipe transport and turnover device, the auxiliary support foot 6 is extended and supported on the ground to increase the stability of the steel pipe transport and turnover device. The lifting support 3 is lifted by the hydraulic cylinder 5 on the vehicle body 1, and is rotated around the side hinge point of the vehicle body 1, so that the pipe section is turned over by 90°. Two groups of special transport devices are pre-installed in the main tunnel, as shown in the figure, and the pipe section can be placed on the special transport device after being turned over by 90°, without relying on the lifting point at the top to complete the construction. The special transport device can be a multifunctional transport trolley which can walk along the transport track 91, which is a prior art. After the turnover is completed, the special transport device transports the steel pipe section into the next construction stage, at this time the auxiliary support foot 6 of the steel pipe transport and turnover device is retracted, and the steel pipe transport and turnover device is walked to the initial position for the transfer of the next steel pipe section.
