Description

Technical Field

[0001] The present invention relates to the technical field of bridge equipment, and in particular to a rapid positioning construction trolley device for a bridge anti-collision guardrail embedded part device. Background Art

[0002] With the continuous growth of my country's national economy and the development of infrastructure construction, large-scale construction of urban and highway bridges, underpasses, viaducts and other transportation projects is being carried out. In order to ensure traffic order and traffic safety, anti-collision guardrails will be installed in the center and on both sides of the bridge deck.

[0003] Highway crash barriers create a longitudinal separation across the road, separating motor vehicles, non-motor vehicles, and pedestrians, preventing vehicles from making U-turns and pedestrians from jaywalking. If a vehicle collides with the barrier due to loss of control, the impact can be mitigated to the driver and passengers. The collision path of the vehicle with the barrier can be smoothly transitioned, returning the vehicle to its normal course and reducing the possibility of a secondary accident. They can effectively prevent vehicles from running off the road or crossing the central divider into the oncoming lane. They serve as a visual guide for drivers, helping them determine the direction of the road beyond their visual range, particularly at night, during heavy rain, fog, or in snowy conditions. An uneven installation of the barrier can negatively impact the appearance of the barrier, directly impacting the aesthetics of the city. Therefore, crash barriers must be sufficiently strong, smooth, and possess sufficient strength and appearance to ensure traffic safety.

[0004] The protective guardrails currently used on highway bridges are mainly modular steel guardrails. The modular steel guardrails are beam structures fixed by pillars. They rely on the bending deformation and tension of the guardrails to resist vehicle collisions. The anti-collision guardrails have a certain degree of rigidity and toughness, and absorb collision energy through the deformation of the beams. The modular steel guardrails are mainly composed of corrugated beams, beams, columns, barrier blocks, base embedded parts and other components. Damaged parts are easy to replace, and they have a certain visual induction effect. They can be coordinated with the road line and have a beautiful appearance. The modular steel guardrails rely on the embedded parts of the base for stability. Before installing the guardrail, the embedded parts of the guardrail must be reserved on the roadbed in advance. The installation quality of the embedded parts directly affects the overall firmness and appearance quality of the subsequent guardrail. Therefore, higher requirements are placed on the installation of the embedded parts of the anti-collision guardrail.

[0005] At present, the conventional construction process of the embedded parts device of the anti-collision guardrail project requires the control line and elevation control line of the embedded parts device to be drawn from the measurement control network for positioning. It is necessary to set a relative elevation point on the fixed bracket pile for welding and fixing, fix the bolts according to the positioning line, and then adjust the elevation and perform temporary reinforcement according to the requirements of the plan. The placed bolts and embedded parts device are adjusted and checked. When they meet the specifications, the lower part of the bolt and the fixed frame are welded. This traditional construction method not only has the problems of complicated positioning steps and inability to accurately position, slow positioning and installation speed, but also leads to inaccurate horizontal and vertical positioning of the embedded parts device, which in turn leads to the installation quality of the embedded parts device failing to meet the construction requirements, causing great hidden dangers to the subsequent guardrail installation, which is something that technical personnel in this field do not want to see. Summary of the Invention
