Description

Technical Field

[0001] The invention relates to the field of engineering machinery, and in particular to a counterweight tray with a rotation warning light and engineering machinery. Background Art

[0002] Engineering machinery: refers to the mechanical equipment necessary for comprehensive mechanized construction such as earthwork, stonework, mobile lifting and loading and unloading, and various construction projects, as well as mechanized operations in industrial production processes related to the above projects; it can also be simply defined as: mechanical equipment used for various types of construction projects and construction tasks are collectively referred to as engineering machinery. Turntable: A key load-bearing structural component in the main engine of engineering machinery, which can be installed with power system, hydraulic system, electrical system, transmission system, counterweight, etc., and it can rotate 360 ​​degrees relative to the lower part. Counterweight: A heavy object used to balance a moving part; usually installed at the tail of the turntable of the engineering machinery, connected to the turntable by a pin shaft, and separated from the turntable during transportation; usually composed of a counterweight tray at the bottom and a counterweight block above the tray, installation accessories, etc. Rotation warning light: A warning light installed at the tail of the rotating part of the engineering machinery. When the engineering machinery is rotating, the rotation warning light emits an audible and visual alarm to remind the surrounding workers to pay attention to avoid it. Rotation radius: The straight-line distance from the outermost edge of the rotating part of the engineering machinery equipment to the rotation center line.

[0003] Cranes, excavators, rotary drilling rigs, etc. are all common construction machinery in daily life. They all have the function of rotating operation and are large in size. Counterweights are configured at the tail of the turntable, and the counterweights must be separated from the turntable during transportation. According to relevant design specifications or customer requirements, these construction machinery should issue an alarm when performing a rotating action to alert people near the equipment.

[0004] The common rotation warning light in the prior art is installed on the top of the counterweight block at the tail of the turntable, and adopts a magnetic suction type; Advantages: The lines are fixed on the turntable, and the magnetic suction type is convenient for disassembly and assembly. During transportation, the rotation warning light can be quickly disassembled and transported separately; Disadvantages: The fixing point is too high (higher than the horizontal line of sight of people) and is not at the outermost edge of the maximum rotation radius, so the warning effect cannot achieve the best effect.

[0005] Or the slewing warning light can be installed on the outside of the tail of the turntable, near the position below the counterweight; Advantages: The overall installation point is located on the turntable, which is easy to implement. During transportation, the electrical control circuit does not need to be disassembled, and there is no risk of water ingress or collision; It is low to the ground (basically flush with people's sight), and the warning effect is better than that placed on the top of the counterweight; Disadvantages: The installation point is not at the position with the largest slewing radius and the outermost edge, so the warning effect cannot achieve the best effect.

[0006] In summary, the installation positions of the above two types of rotation warning lights are not ideal. Therefore, it is necessary to develop a new type of counterweight tray and engineering machinery with a rotation warning light to overcome the problems of the prior art. Summary of the invention
