Description

Technical Field

[0001] The invention relates to the field of bridge erection machine equipment, and in particular to a device integrating a bogie of a beam transport vehicle and a bridge erection and beam feeding mechanism. Background Art

[0002] With the continuous development of my country's railways, the span of prefabricated bridge piers erected on railway lines is getting larger and larger, and the length of the erected concrete box beams is also increasing, which puts higher and higher requirements on bridge erection machines.

[0003] Traditional bridge erection machines are separated in beam transport and beam feeding. The beam transport vehicle transports the pre-supported beam to the designated location, and then a beam transport trolley on the bridge erection machine lifts one end of the pre-supported beam and moves it to the appropriate location, and then another beam transport trolley lifts the other end of the pre-supported beam, and finally completes the entire beam feeding process. The whole process involves three mechanisms and is time-consuming. In order to solve the above technical problems, a device is provided that integrates a beam transport vehicle bogie with a bridge erection beam feeding mechanism. Summary of the invention

[0004] In order to solve the above technical problems, the object of the present invention is to provide a device integrating a beam transport vehicle bogie and a bridge erection and beam feeding mechanism.

[0005] The technical problems to be solved by the present invention are:

[0006] The present invention can realize both rapid transportation of pre-supported beams and rapid feeding of pre-supported beams by means of the oil cylinder, the pin shaft and the beam transporting mechanism. The integrated mechanism is designed so that beam transport and beam feeding can be completed continuously without the need for a conversion mechanism in between, thus saving time, improving efficiency and greatly improving the safety of the device, thereby solving the technical problem in the prior art that the beam transport and beam feeding processes of the bridge erecting machine are separate and involve many mechanisms, which is time-consuming.

[0007] The purpose of the present invention can be achieved through the following technical solutions:

[0008] A device integrating a beam transport vehicle bogie and a bridge erection beam feeding mechanism, comprising two beam transport vehicles, a pre-support beam, a main beam mechanism, a beam pier and a suspension frame, wherein the main beam mechanism and the beam transport vehicle are both erected directly above the beam pier, the pre-support beam is respectively connected and fixed to the two beam transport vehicles, and the suspension frame is fixed on a side of the main beam mechanism away from the beam transport vehicle;

[0009] The beam transport vehicle comprises a frame and a plurality of parallel running wheels located on the outer surface of the lower end of the frame, and a beam transport mechanism is fixedly installed on the outer surface of the upper end of the frame;

[0010] The beam transport mechanism comprises a bearing frame and a sliding wheel. The bearing frame is fixedly mounted on the outer surface of the upper end of the frame, and the sliding wheel is movably connected to the inner side wall of the bearing frame.

[0011] Furthermore, a pin shaft is movably mounted on the outer surface of the upper end of the beam transport vehicle, and an oil cylinder for controlling the lifting of the pin shaft is fixedly mounted on the outer surface of one side of the beam transport vehicle.

[0012] Furthermore, the pin shaft is connected and fixed to the beam transport mechanism through oil cylinder lifting.

[0013] Furthermore, a track is laid between the frame and the supporting frame, and the track and the sliding wheel are mutually matched structures.

[0014] Furthermore, the specific method of using the device integrating the bogie of the beam transport vehicle and the bridge erection and feeding beam mechanism is as follows:

[0015] S1: When transporting the pre-supported beam, fix the bearing frame on two beam transport vehicles, lift the pin shaft through the oil cylinder, so that the beam transport mechanism is connected and fixed with the beam transport vehicle, then fix the pre-supported beam on the bearing frame, and transport the pre-supported beam by the beam transport vehicle;

[0016] S2: When the pre-supported beam is transported to the designated position, the beam feeding operation is performed. The pin shaft is controlled to descend by the oil cylinder, so that the beam transport mechanism is separated from the beam transport vehicle. Then, under the sliding action of the sliding wheel on the track, the pre-supported beam is sent to the designated position to complete the beam feeding process.

[0017] Beneficial effects of the present invention:

[0018] The present invention can realize both rapid transportation of pre-supported beams and rapid feeding of pre-supported beams by means of the oil cylinder, the pin shaft and the beam transporting mechanism. The integrated mechanism is designed so that beam transportation and beam feeding can be completed continuously without the need for a conversion mechanism in between, thus saving time, improving efficiency and greatly improving the safety of the device. When in use, the carrier frame is fixed on two beam transporting vehicles and connected to the vehicle frame through the pin shaft, wherein the pin shaft can be controlled to rise and fall by the oil cylinder. When the pre-supported beam is to be transported, the pin shaft is lifted by the oil cylinder so that the beam transporting mechanism and the beam transporting vehicle are connected together, thereby realizing the beam transporting process; when the pre-supported beam is transported to the designated position, the pin shaft is controlled to descend by the oil cylinder so that the beam transporting mechanism and the beam transporting vehicle are out of contact, so that the beam transporting mechanism can deliver the pre-supported beam to the designated position through the rails on the beam transporting vehicle and the main beam mechanism, thereby completing the beam feeding process.
