TECHNICAL FIELD

[0001] The present application relates to the field of pipeline transportation, in particular to a typhoon and flood prevention intelligent immersed tube transportation trolley system. BACKGROUND

[0002] The immersed tube is a hollow long strip circular pipe material, which is mainly widely used in industrial conveying pipelines such as petroleum, chemical industry, medical treatment, food, light industry, machinery and instrument, and mechanical structure parts. Due to its large volume, a transportation base or trolley system is often needed to assist in ground or water transportation.

[0003] Especially when long-distance large-scale immersed tube construction is carried out on water, the problems of large engineering quantity and high construction difficulty make the project construction period longer, which leads to high risk of typhoon and large water level change in the process.

[0004] Therefore, a typhoon and flood prevention intelligent immersed tube transportation trolley system is urgently needed. SUMMARY

[0005] In order to avoid the above problems existing in the prior art, the purpose of the present application is to provide a typhoon and flood prevention intelligent immersed tube transportation trolley system.

[0006] In order to achieve the above purpose, the present application provides the following technical scheme: a typhoon and flood prevention intelligent immersed tube transportation trolley system, comprising a central control system, a trolley track, a trolley, an information monitoring mechanism and a lifting mechanism; The trolley track is laid from top to bottom along a certain slope to the water edge, and a plurality of trolleys are uniformly arranged on the trolley track; the information monitoring mechanism comprises a length detection device and a liquid level sensor, the liquid level sensor is arranged in water, the length detection device is arranged at the end of the trolley track, and the trolley is provided with a lifting mechanism; The lifting mechanism and the information monitoring mechanism are respectively connected with the central control system, and the central control system controls the lifting mechanism to adjust the water inlet height of the immersed tube based on the data monitored by the information monitoring mechanism.

[0008] After the trolley is transported to the end of the track, the trolley is separated from the immersed tube, slides down the slope into the recovery groove, stops the trolley through the stopping plate, and then the trolley is transported back to the starting point of the trolley track by other equipment or manpower to wait for transportation of the immersed tube.

[0009] The present application is further provided that a bevel operation position, a welding operation position and a corrosion prevention operation position are sequentially arranged from top to bottom along the trolley track. The beveling operation position is used to align the unconnected pipe joint with the connected pipe joint; the welding operation position is used to weld the aligned pipe joint; and the anti-corrosion operation position is used to apply anti-corrosion coating to the welded pipe joint.

[0010] The present invention is further configured such that each trolley is equipped with an NFC chip, the NFC chip contains the trolley number, an NFC sensor is provided on one side of the trolley track, the NFC sensor is signal-connected to the central control system, and the NFC sensor is located at the front end of the welding operation position.

[0015] The roller can be made of aluminum with a hard polyurethane rubber sintered on its surface. It can rotate as the tube moves. With the help of a rotary encoder, the number of rotations of the roller is converted into a pulse signal. The length of the tube that has passed is obtained by calculating the number of pulses multiplied by the circumference of the roller.

[0016] The present invention is further configured such that the Hall sensor assembly is suitable for detecting a submerged tube with a stiffening ring, the Hall sensor assembly including a Hall sensor and a sensing magnetic sheet, the sensing magnetic sheet being disposed on the stiffening ring.
