Description

Technical Field

[0001] This utility model relates to the field of bridge building equipment technology, and in particular to a bridge building machine traveling device. Background Technology

[0002] The bridge-building machine traveling device refers to the core component system used to support and move bridge-building machines (such as bridge erecting machines, mobile formwork, and other large bridge construction equipment) during bridge construction. Its function is to enable the bridge-building machine to travel longitudinally, laterally, or in curves during the bridge construction process, so as to adapt to the operational needs of different spans, alignments, and construction stages, while ensuring the stability, safety, and accuracy of the equipment during movement.

[0003] Currently, bridge-building machines use a diamond-shaped basket construction system. Its main load-bearing structure is the diamond frame, while the traveling structure consists of a manhole jack, precision-rolled threaded steel bars, and traveling attachments. The traveling method is towing, where one end of the precision-rolled threaded steel bar is anchored to the traveling attachment at the front of the track, and the other end passes through a sliding support and a hydraulic manhole jack, and is fixed to the tail of the hydraulic jack. The extension thrust of the manhole jack pushes the diamond frame forward. The entire operation is complex, the structure is prone to deformation, and the track needs to be manually moved forward, re-assembled and anchored, and then the diamond frame slowly pushed forward again. This process is time-consuming and slow. Furthermore, the diamond basket structure has a high center of gravity, numerous pre-drilled holes, a high risk of overturning, and requires many manual steps with low automation. Therefore, there is an urgent need to design a new type of bridge-building machine traveling device to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a bridge-building machine traveling device to solve the problems of existing bridge-building machine traveling devices using the diamond basket construction method, such as complicated operation, easy structural deformation, long cycle time, slow speed, high risk of overturning, and low level of intelligence.

[0005] To solve the above technical problems, this utility model provides a bridge-building machine traveling device, including a traveling beam and a main beam. The top surface of the traveling beam is rotatably connected to a pushing cylinder and a locking cylinder. The piston rod of the pushing cylinder is rotatably connected to the side of the locking cylinder. The main beam is located above the traveling beam and its bottom surface is provided with a steel rail. The top surface of the traveling beam is also provided with a traveling wheel, and the top of the traveling wheel is located on the steel rail.

[0006] Both ends of the main beam are equipped with support leg beams, and the bottom of the support leg beams is fixed with a lifting cylinder.

[0007] As a further improvement to the above technical solution:

[0008] Optionally, the top surface of the traveling beam is provided with a counter-pressure wheel box and a tank wheel, the counter-pressure wheel box is provided with a counter-pressure wheel, and the counter-pressure wheel and the tank wheel are connected to the bottom end of the beam.

[0009] Optionally, a front support is also provided on the top surface of the traveling beam, and the front support is located at the bottom end of the main beam.

[0010] In the bridge-building machine traveling device provided by this utility model, a pushing cylinder and a locking cylinder are rotatably connected to the top surface of the traveling beam. The piston rod of the pushing cylinder is rotatably connected to the side of the locking cylinder. The main beam is located above the traveling beam and a steel rail is provided on its bottom surface. The top surface of the traveling beam is also provided with a traveling wheel, the top of which is located on the steel rail. Leg beams are installed on both sides of the main beam, and a lifting cylinder is fixed at the bottom of the leg beam. By using the bridge-building machine traveling device, through optimizing the structural design of the traveling beam and the main beam, and combining components such as the pushing cylinder, locking cylinder, traveling wheel, and lifting cylinder, modular and intelligent control of the traveling device is achieved. This solution, starting from structural integration and functional synergy, solves the core problems of poor flexibility and insufficient stability of traditional traveling devices, and provides an efficient and reliable mobile support solution for bridge construction.

[0019] Operating procedures

[0020] First, the front lifting cylinder 9 extends to lift the main beam 2, remove the pad on the front support 7, and remove the anchor of the traveling beam 1. Then, both lifting cylinders 9 extend simultaneously, lifting the main beam 2 and causing the traveling beam 1 to detach from the bridge contact surface. Next, the locking cylinder 5 is released, and the pushing cylinder 4 extends to the set maximum position. At this time, the locking cylinder 5 is locked, and the pushing cylinder 4 is retracted. The above actions are repeated to move the traveling beam 1 forward until it reaches the set position. At this time, the locking cylinder 5 is locked, and the pushing cylinder 4 extends (moving the main beam 2 to complete a section of forward movement). The locking cylinder 5 is released, and the pushing cylinder 4 is retracted. The above actions are repeated to move the main beam 2 forward to the set position, preparing for the next stage of construction.
