Description

Technical Field

[0001] The utility model relates to a bridge crane for lifting operations in metallurgy, machinery and other industrial and mining industries and transportation industries, and more specifically, to a positioning warning device for a high-place track beam of a bridge crane. Background Art

[0002] Lifting, hoisting and barging operations are common operating procedures in industrial and mining enterprises such as metallurgy, machinery, and transportation industries. Bridge cranes (commonly known as cranes and overhead cranes) are common lifting equipment.

[0003] The two ends of the bridge crane are located on tall concrete columns or metal brackets, and the shape resembles a bridge, hence the name. The bridge crane is a lifting equipment that is horizontally mounted in the upper space of industrial buildings such as workshops and warehouses and above outdoor material yards to lift materials. The bridge of the bridge crane runs longitudinally along the tracks laid on the elevated platforms on both sides, and can make full use of the space under the bridge to lift materials without being hindered by ground equipment. Therefore, it is the most widely used and largest type of lifting machinery.

[0004] As far as the operation of bridge cranes in industrial buildings is concerned, it is mainly the reciprocating operation of the bridge crane on the high rail beams in the building through the wheels at the bottom of the beam. Therefore, in production practice, the bridge crane and the high rail beams will undergo fault inspection and repair operations as well as regular maintenance operations, which are essential procedures in the daily use of bridge cranes.

[0005] When inspecting and repairing bridge cranes and high-altitude rail beams, or carrying out regular maintenance, the first step is to locate them, that is, to stop the bridge crane at a designated workstation to carry out related operations; in the event of a sudden failure of the bridge crane and it cannot operate, emergency repairs can also be carried out at the faulty workstation. Regardless of the operation method, warning signs need to be set up in the operation area.

[0006] At present, "red and white belts" are used as warning signs in industrial and mining enterprises. The so-called "red and white belts" are composed of red and white pennants, with a length of more than 10 meters. When used on site, track clamps are set on the outside of the wheels on both sides of the bridge crane that needs to be inspected, repaired or maintained (if the bridge crane is parked at a wall-mounted station, it is only on the side not against the wall), and a "red and white belt" warning line is set 10 to 15 meters outside the track clamp. The purpose is to inform adjacent bridge cranes not to enter the maintenance area to prevent collision accidents; at the same time, inform ground personnel not to enter the bottom of the maintenance area to prevent injuries from falling from heights.

[0007] The "red and white belt" has been used as a warning sign for many years and is widely used. It can serve as a warning sign, but it still has the following shortcomings:

[0008] 1) The vision is unclear due to environmental influences, which weakens the warning function: The "red and white belt" is installed on the high track beam and is directly affected by the height of the track beam. It is also affected by factors such as night time, weather, lighting, and colors in buildings, which causes unclear vision to a certain extent and weakens the warning function.

[0009] 2) Only visual warning function affects the warning effect: The "red and white belt" realizes the guidance and warning functions through visual discovery → feedback → warning. In industrial buildings, there is only a single visual method, which is particularly restricted by the environment and is not conducive to the full play of the warning effect.

[0010] 3) Safety first in height operations: Bridge crane and high-altitude rail beam operations are considered height operations. Warning lines must be set up at the work station and on the ground below it to implement area closure to ensure operation safety. Therefore, warning signs are the core measure for area closure and their functions must be guaranteed to be effective.

[0011] In summary, high-altitude warning signs are essential technical measures in the inspection, repair and maintenance of bridge cranes and rail beams, and are also necessary safety devices. The traditional "red and white belt" warning line is affected by the environment and is not conducive to the online warning function. It is necessary to make corresponding technical improvements to achieve sound and light warnings, overcome the adverse factors in industrial buildings, play an effective guiding and warning role, and further improve the warning efficiency, so as to ensure the safety of high-altitude operations and effective regional closure.
