Description

Technical Field

[0001] The invention relates to a mobile crossing frame with buffering energy absorption, lifting cleats and track monitoring, and belongs to the technical field of mechanized equipment for power line crossing construction. Background Art

[0002] In the construction of power lines, it is inevitable to carry out three-span operations, that is, crossing roads, railways and power lines. In order to protect these facilities and ensure construction safety, a crossing frame must be erected to protect them. In the three-span operation, especially crossing the live line, the contradiction is the most prominent. Using ordinary crossing frame erection or layout technology, in order to ensure the construction safety of the crossing frame erection, network closure layout, network closure evacuation, and crossing frame dismantling, the crossed power line must be shut down. However, ensuring that the power supply line is not shut down is the social responsibility and service goal pursued by the power industry. The State Grid Corporation of China clearly stipulates in the "State Grid Corporation Power Supply Service Specifications" that the number of power outages for customers with a voltage level of 35 kV and above should not exceed 1 per year; for customers with a voltage level of 10 kV, it should not exceed 3 times per year; with the acceleration of my country's power grid construction and transformation and the world's most developed power supply network, the situation of crossing power lines during line construction is ubiquitous. Therefore, when the construction of power lines crosses over energized lines, ensuring power supply and ensuring safety are two irreconcilable contradictions, which makes it extremely difficult for the line construction department to approve power outage applications. In desperation, illegal crossing construction without power outages will occur.

[0003] In order to resolve this difficult-to-reconcile contradiction, a mobile automatic fast-deployable crossing frame is disclosed in the prior art, with the announcement number CN205452971U. The crossing frame realizes the protection of the object by supporting the umbrella-shaped crossing frame above the object to be crossed through a car crane. The mobile crossing frame is widely used for its safety, convenience, economy and solution to the problems of manual high-altitude and near-electrical operations. Later, its function was innovated and a mobile umbrella-shaped crossing frame with rotation and pitching functions was introduced, with the announcement number CN 216598743 U. It was improved from a simple mobile quick-deployment crossing frame using the umbrella principle to a mobile umbrella-shaped crossing frame with rotation and pitching functions. In order to meet the needs of construction use, the prior art has introduced a mobile umbrella-shaped crossing frame with three functions, namely, a near-electricity alarm system, a front and rear sealing device, and a state change alarm system after deployment, such as the patent application with the publication number CN 117335320 A. The mobile umbrella-shaped crossing frame can safely carry out completely non-power-off crossing construction when the construction site has a large space, the live lines and the surrounding environment are good, and the electromagnetic environment is good, and can adapt to most construction conditions. However, this type of mobile umbrella-shaped spanning frame also exposes its imperfections in the application of spanning construction without power outages. The reason is that the above technology does not have a safety monitoring system specifically for the layout and movement trajectory of the mobile umbrella-shaped spanning frame during evacuation. When used on site, it will be difficult to use due to design errors in the special spanning construction plan, on-site layout errors, inaccuracy of near-electric sensors in complex electromagnetic environments, inability to install near-electric sensors on the boom of the truck crane for near-electric monitoring, multiple parallel power supply lines leading to tight space for spanning frame layout, irregular operation of truck cranes and spanning frames, etc. In addition, in order to reduce the construction cost of the line tower, the power line design department The tower height is kept as low as possible while ensuring that the safety distance at the intersection of power lines is sufficient, so that in many cases the height difference between the newly installed line and the crossed line at the intersection does not exceed the safety distance by much. The height dimension from the top of the existing horn to the bottom of the sealing plane is close to 4 meters, which often results in the mobile umbrella-shaped crossing frame not being able to be safely removed from the upper and lower power lines, causing the boom of the truck crane and the crossing frame to be too close to or contact the live line, which may cause the crossed live line to trip at the least, causing significant economic losses to power users, and serious safety accidents such as personal injury to the truck crane operator and construction workers on nearby construction lines.

[0004] Therefore, in order to further ensure construction safety and facilitate safe and convenient use on site, it is necessary to add devices such as a liftable horn device, a main load-bearing roller buffer energy absorption device, and a safety monitoring system for the moving trajectory during arrangement and evacuation to the existing mobile umbrella-shaped crossing frame to ensure the safety of the mobile crossing frame during arrangement and evacuation without power outages on the crossed power lines, so that the advantages of the mobile umbrella-shaped crossing frame cannot be fully utilized.

The buffer support rod 70104 can freely move up and down in the circular tube in the middle of the main load-bearing truss 10204. Under the action of the elastic force of the buffer spring 70102, the buffer support rod 70104 is pushed to the top, and the upper end surface of the circular axis in the middle section of the buffer support rod 70104 and the upper end surface of the circular tube in the middle of the main load-bearing truss 10204 form a space in which one end can move freely; when an accident occurs, the newly built conductor 2 suddenly breaks and contacts the buffer energy-absorbing device 7 of the main load-bearing roller, and an impact force is generated between the newly built conductor 2 and the buffer energy-absorbing device 7 of the main load-bearing roller. After a period of displacement and deceleration, the newly built conductor 2 and the buffer energy-absorbing device 7 of the main load-bearing roller are relatively stationary, and the impact process ends.

When the velocity change V is constant, the larger the displacement change S is, the longer the movement time t is.

[0028] The free movement space can increase the time t for the buffer energy-absorbing device 7 to act from contact to static force after the newly built conductor 2 suddenly breaks and impacts the main bearing roller during an accident.

Because the buffer energy absorption devices 701 at both ends have free movement space, in the state of a crossing construction accident, the impact force between the newly built conductor 2 and the buffer energy absorption device 7 of the main bearing drum is reduced (according to the impulse theorem of classical mechanics, , where P is the change in impulse of the newly built conductor 2 contacting the buffer energy absorbing device 7 of the main load-bearing roller during the accident, F is the force of the newly built conductor 2 contacting the buffer energy absorbing device 7 of the main load-bearing roller, and t is the time for the newly built conductor 2 to contact the buffer energy absorbing device 7 of the main load-bearing roller to exert its static force during the accident.
