MOBILE TELESCOPIC LIGHTING TOWER Russian patent published in 2023 - IPC F21V21/22 

FIELD: lifting and transport mechanisms.

SUBSTANCE: invention is related to mobile lighting installations, and can be used in construction, repair, installation and many other types of work. Mobile telescopic lighting tower, containing a steel frame on a wheelbase, a telescopic boom fixed on the frame, consisting of stationary and movable parts, including sections interconnected by roller blocks and a block-chain system, a lighting crown located on the movable part of the telescopic boom, fixed side braces on the frame and the telescopic boom, telescopic boom motion drive and folding outriggers pivotally mounted on axles at the corners of the frame, characterized in that the frame contains a hollow frame made of square pipes with linings located above and below the frame, interconnected by stiffening ribs , wherein the length of one side of the frame is greater than the other side of the frame by at least the width of the outrigger, the bottom of the frame is reinforced with a solid sheet, provided with at least one compartment, in the hollow frame of the frame there are reciprocal holes for the forks of the loader, the shape of which corresponds to the shape of the forks of the loader, each outrigger contains a spring retainer and a jack, including a sleeve of square section, inside of which a square rod with a screw is installed through antifriction bushings of round section, connected to a ball bearing installed in the base, the side braces are not parallel to each other, and the side braces are attached to the telescopic mast in the uppermost point of the stationary part of the telescopic mast through the bracket. The telescopic boom motion drive consists of a DC motor, a worm gear, a thrust cup with a bearing, a lead screw and a nut, the DC motor and the worm gear are fixed to a solid frame sheet from below, the thrust cup is from above, and the lead screw is located inside the first section of the movable part of the telescopic boom, which is attached to its threaded part through a nut, is fixed in the thrust cup with a bearing and is connected to the worm gearbox by means of a key connection. Additionally, the lighting mast contains a revolving unit, a controller that limits the maximum wind load on the lighting crown and the angle of the lighting mast, a light beacon, a wind speed sensor and a telescopic boom angle sensor connected to the controller. The tilt angle sensor is installed at the bottom of the stationary part of the telescopic mast in a groove. The lighting crown consists of a frame made of square tubes and round tubes, as well as sheet metal, with brackets and fixtures. The lighting crown is mounted on the telescopic tower with the possibility of quick removal by means of the lower and upper grips, the lower grip is a lower bracket with hooks, and the upper grip consists of an upper bracket with hooks, in the grooves of which a hinged bracket with a spring-loaded lock and containing recesses on the side slats for a round tube of the lighting crown frame, a light beacon and a wind speed sensor are installed on the lighting crown frame. The reversing assembly includes a U-shaped reversing lever telescopically located in the hollow frame of the frame, a wheel block rigidly fixed to the stationary part of the telescopic boom, a latch consisting of a bracket and a spring-loaded pin fixed to the stationary part of the telescopic boom, a thrust block mounted on the stationary part of the telescopic boom, parts of a telescopic boom with the ability to move along it, and skis located on the rear side of the frame, while the thrust block includes two sidewalls, spacers connecting the sidewalls to each other, a folding hook and a scraper pivotally mounted in the sidewalls by means of the scraper axis.

EFFECT: increased reliability of operation of the lighting tower and its components under extended operating conditions, elimination of traumatic operations for preparing the lighting tower for operation or transportation, automation of safety control and increased ease of operation while simplifying and increasing the speed of preparatory operations.
