Angle-variable illuminating lamp of crane and application method of angle-variable illuminating lamp

Abstract

The invention discloses a variable-angle illuminating lamp for a crane and an application method thereof, and aims to solve the problem that the probability of accidents of a common crane working at night is high due to the fact that the mounting position of the lamp is too low, horizontal light irradiation during illumination is limited, and objects and constructors on the irradiation surface have large shadows. Objects in other directions and constructors cannot see clearly, when the constructors stand in a light shielding area for construction, crane operators can only see part of the constructors and equipment, and therefore large potential safety hazards are generated, and the safety protection device has the advantage that safety can be improved in places with poor light.

Description

Technical Field

[0001] This patent invention belongs to the field of crane technology and redesigns the crane's variable-angle lighting and its application method. Background Art

[0002] Generally, the probability of accidents occurring when cranes are working at night is higher. The reason is often that the installation position of the lamps is too low, and the horizontal light is limited during lighting. Objects and construction workers on the illuminated surface have large shadows, and objects and construction workers in other directions cannot be seen clearly. When construction workers stand in the light-blocked area to work, the crane operator can only see some construction workers and equipment, which creates a major safety hazard. Summary of the invention

[0003] Design purpose: In order to overcome the shortcomings of the existing technology, a variable angle lighting solution for cranes is provided, which is installed at a higher position of the crane. The lighting from top to bottom allows the crane operator to better see the position of the construction workers and the surrounding environment.

[0004] Design plan: In order to achieve the above design purpose, the structural design of this patent invention is as follows: a variable-angle lamp holder and a lighting lamp are installed below the front end of the first section of the crane's boom, below the front end of the crane's jib, or below the middle of the crane's jib, and are connected to the crane's onboard power supply via quick-release connector wires.

[0005] Technical solution: The first solution is a variable angle light stand for cranes. The fixed bracket is connected to the crane jib by bolts. A rotatable bearing is installed at the center of the bracket. The bearing is connected to another small bracket, and the lamp is installed on the small bracket. The bracket changes the lighting angle due to gravity traction. Due to the bearing connection, the lighting angle of the lamp always remains toward the ground when the crane changes its position. The second solution is a variable angle light stand for cranes. The fixed bracket is connected to the jib by bolts. A variable angle motor is installed at the center of the bracket. The angle change is controlled by remote control. The variable angle motor is connected to the small bracket. The lamp is installed on the small bracket. Due to the existence of a variable angle motor, the direction of illumination can be manually controlled. The variable angle light stand installed in the middle is the same as the above solution, but the installation method is different. The third solution is a variable angle light stand for cranes. The variable angle light stand and the lamp can be installed under the front end of the first section of the crane's boom to keep the illumination angle always toward the ground.
