Description

Technical Field

[0001] The utility model relates to a two-way passage inspection frame, belonging to the field of mechanical equipment. Background Art

[0002] The dynamic offset of heavy railway vehicles during operation due to factors such as line conditions and passing speed is difficult to grasp, which brings safety risks to the transportation of oversized and oversized goods by rail. In order to ensure the transportation safety of equipment, for railway sections with relatively poor clearance conditions and dense bridges and tunnels, a simulated transportation test is usually carried out on the inspection frame before formal transportation.

[0003] The main body of the inspection frame is usually made of steel structure, which generally consists of two parts: a fixed bracket and a movable bracket. In addition, supporting equipment also includes reinforcement materials, lighting equipment, and video acquisition equipment. During the transportation test of the inspection frame, a specialist will be assigned to accompany the vehicle to monitor the inspection frame through video surveillance in the vehicle to see if there are any scratches or collisions, and record the corresponding locations and equipment. After that, the person in charge of the relevant railway bureau will be notified and an on-site inspection and rectification will be organized.

[0004] The current inspection frame test mode is relatively mature, and there are many successful cases of ensuring the safety of special train transportation through the inspection frame test. However, there are still many problems that affect the accuracy of the inspection frame test results and need to be solved urgently. The following are two main problems.

[0005] First, due to structural design reasons, the current inspection frames are all one-way inspection frames, that is, the inspection frames after installation can only move in the opposite direction of the vehicle's forward movement. Therefore, when installing the inspection frame, it is necessary to determine the installation direction in advance. At the same time, for transportation routes that need to change direction in the middle, it is necessary to reinstall the inspection frame in a conditional site, or conduct multiple inspection frame tests. In addition, the activity angle and rebound force of the one-way inspection frame rebound device are nonlinear, and there is a problem that when the collision force is too large, it cannot rebound, or the rebound force is too large, resulting in limit displacement.

[0006] Secondly, during the inspection frame test, monitoring personnel are required to monitor the entire process through video acquisition equipment to observe whether the inspection frame has any scratches or collisions. Since the monitoring camera's observation angle is not directly facing the position, there is visual dislocation when observing with the naked eye, which leads to deviations in the observation results. In addition, personnel will inevitably become tired and distracted after monitoring for a long time, resulting in missing collision points. Both of these situations will reduce the credibility of the observation results and will also cause uncontrollable risks in formal transportation. Utility Model Content
