Description

The invention relates to lifting and transport mechanisms, namely to mobile lighting installations and can be used in construction, repair, installation and many other types of work.

Mobile telescopic lighting towers are versatile and have a wide range of applications. In particular, they can be used to organize the lighting of sites in various industries. Such installations are especially in demand for high-quality lighting of construction sites, industrial areas, roads, highways, highways, roadwork sites, logistics sites, warehouses, storage facilities, closed regime facilities, farms, fields, mining sites for various minerals, airports and airfields (mobile lighting can be both emergency and as additional light sources), railway stations, bus stations with sites for temporary parking of vehicles, venues for public events with a large crowd of people, sports stadiums, ice rinks, courts and other structures.

Mobile lighting masts of the telescopic type are free-standing hoisting machines, the stability of which is ensured only by their own gravity. When working, they rely on side safety stops (outriggers), which allows you to have the necessary margin of stability.

The weight of such installations can vary from 450 kg to 700 kg, overall dimensions from 1200 to 1450 mm.

Light weight allows the use of mobile lighting masts both outdoors and indoors, where the load on the floor can be limited. Due to their compactness and lightness, mobile lighting masts can be transported through narrow aisles and corridors, moved between floors in freight elevators.

Mobile telescopic lighting masts are equipped with a wheel base, which allows them to be moved manually over short distances.

When transporting mobile lighting masts over long distances, a vehicle is used. The units can be towed both behind the vehicle and inside it - in the back of a truck, for example, a cargo gazelle GAZ 2705, 27075, GAZ 3302, etc.

Loading and unloading of a mobile telescopic type lighting mast from a vehicle body can be carried out by personnel manually or with the help of a loader, the forks of which are brought under its supporting frame, as well as by a crane.

The use of mobile telescopic lighting masts refers to high-risk work, during which injuries and other accidents may occur that threaten the health and life of people, caused, in particular:

- loss of stability and overturning of the mobile lighting mast for various reasons: high center of gravity, insufficient support contour when using short outriggers, unintentional folding of the outriggers, insufficient rigidity of the telescopic mast, deviation of the mast from the vertical position, etc.;

- mechanisms, movable and protruding parts of the lighting mast;

- technical malfunctions of lighting mast units;

- the complexity and injury risk of operations to prepare the lighting tower for operation and transportation.

The closest analogue of the claimed mobile lighting tower (prototype) can be attributed to the lifting type mobile lighting tower disclosed in the patent CN 2886338 (Y), 04.04.2007, WU YINXI (CN). This lighting tower includes a movable frame on wheels, a generator mounted on the frame, an air compressor, an electronic control device, a retractable profile mast, a hydraulic pump, and a lighting crown equipped with lamps and lanterns. The frame design is specially shaped to allow the mast to be towed behind the vehicle. The product is suitable for field operations, night rescue and disaster relief, maintenance and repair, etc. The cross section of each profile of the telescopic mast has a rectangular shape, and on the sides, respectively, a guide plate and a chute are provided so that adjacent profiles are slidably connected through the guide plate and the chute. The lower part of the mast is fixed to the frame. The lifting gear of the telescopic mast consists of hydraulic cylinders, chain and pulleys. The lighting crown is made removable and is located on a rotating shaft with the possibility of adjusting the lighting angle from the drive. The frame is equipped with supports (outriggers located at the corners of the frame) for fixing the lighting mast in the working position. The telescopic mast is equipped with parallel braces, made of aluminum alloy, the surface is anodized and has anti-corrosion treatment.

The disadvantage of the prototype is the high risk of injury to operating personnel and people in close proximity to it, and as a result, insufficient safety when operating the lighting tower in advanced performance indicators (ambient temperature, weather conditions, wind loads, lifting height, etc.), and also when preparing the lighting tower for operation or transport.

These shortcomings are due to:

- the possibility of overturning of the lifting-type lighting mast due to insufficient stability caused by the small size of the outriggers and the risk of their unintentional folding during operation; the resulting support contour does not ensure the stability of the light tower for work at a height of 10 m and / or with wind gusts of 12.5 m / s, i.e. the use of a prototype to perform work in such performance indicators is unsafe;

- the possibility of overturning of the lighting mast due to insufficient rigidity of the telescopic mast with extended performance, caused by the use of parallel braces for fixing the telescopic mast (in case of lateral gusts of wind, parallel braces do not perceive the load on compression / extension, but perceive the load on shear and transverse bending, which adds additional load in the form of a transverse bend to the telescopic mast), low location of the attachment point of the braces to the telescopic mast;

- the possibility of overturning the lighting mast when the telescopic mast moves at an angle exceeding the permissible angle of inclination;

- the possibility of unauthorized lowering of the lighting tower down in case of an abnormal breakdown of any elements of the hydraulic system and pollution of the atmosphere and personnel during normal operation of the safety valve when using the lighting tower in extended temperature ranges due to changes in oil viscosity;

- the presence of protruding parts: four outrigger handles and a section of the frame for towing behind the vehicle;

- lack of devices for loading the lighting mast into a vehicle for transportation to another facility; if it is impossible to tow the lighting mast behind the vehicle, loading the mast into the back of a truck in the absence of specialized means will be unsafe;

- lack of places for storing tools and personal belongings of the operator; in the absence of places to store the tool and personal belongings of the operator, the personnel is forced to carry these things in their hands, in practice, if it is necessary to carry out manual operations below, the tool and personal belongings are deposited on the floor and workers concentrated on the task often stumble over things and tools, which leads to their fall, including on the protruding parts of the lighting mast;

- fastening of the lighting crown to the top point of the telescopic mast, which requires personnel to be lifted onto steps, ladders, ladders or other means for working at height in order to mount and dismantle lighting equipment.

Since the work performed with the use of mobile lighting masts is associated with lifting loads to a height (the weight of the lighting crown can be from 70 to 80 kg when lifting to a height of up to 11 m), they are classified as high-risk work, which requires unconditional compliance with the safety requirements set forth in normative legal acts, technical standards and regulations.

However, these requirements are often not met in practice. Due attention is not paid to the technical condition of lifting structures, compliance of lifting structures with the requirements of regulatory documents and compliance with established labor safety requirements when using them. Effective control is not always provided over the use by employees of safe work practices, compliance with the requirements set out in the instructions for labor protection, as well as the correct use of collective and individual protective equipment.

In view of which, at present, the possible options for reducing the risk of injuries and other accidents when using lifting structures, in particular mobile lighting masts of a lifting (telescopic) type are:

- increasing the reliability of the lifting equipment and its components;

- increasing the ease of use (excluding traumatic operations to prepare equipment for operation or transportation);

The claimed mobile telescopic type lighting tower, the general view of which is shown in Fig. 1, 2 and 11 contains a frame (1) on a wheelbase (2), a telescopic boom (3) fixed on the frame, consisting of stationary and movable parts, including sections interconnected by roller blocks and a block-chain system, located on the movable parts of the telescopic boom (З) lighting crown (4) fixed on the frame and telescopic boom (3) side braces (5), telescopic boom motion drive (6) and folding outriggers (7) pivotally mounted on axles (15) at the corners frames (1).

Frame (1), illustrated in detail in FIG. 3 is the supporting structure of a mobile telescopic lighting tower and serves as a frame on which all the nodes of the lighting tower are fixed. The frame (1) is mounted on a wheel base (2), which consists of two front swivel wheels with a parking brake and two rear wheels, which allows you to move the lighting tower in space in the presence of a large number of turns.

The frame (1) includes a hollow frame (8) made of steel square tubes stacked in 2 rows on top of each other, with pads (9). The upper and lower linings (9) are interconnected by stiffening ribs (10), thereby forming a box-shaped section that reduces the deflection of the linings (9) relative to the frame (1). These design solutions make it possible to increase the rigidity of the frame (1) of the lighting mast and increase the stability of the mobile telescopic lighting mast when operating at a height of more than 9 m and / or wind gusts up to 12.5 m/s.

As seen in FIG. 4 the bottom of the frame (1) is reinforced with a power solid sheet

(11), as well as two compartments: a compartment for storing tools or personal belongings of the operator (12) and a compartment for storing power electrics (13). Storage compartments (12, 13) are box-shaped structures welded from steel sheets. Due to these design solutions, the rigidity of the frame structure (1) is also increased, and the center of mass of the frame (1) is shifted as low as possible to the ground, which increases the stability of the lighting tower when operating in extended ranges of operational characteristics, thereby increasing the safety of using the declared lighting tower .

In addition, the presence of compartments (12, 13) allows the operator to store equipment, tools, personal items and power electrics in closed places, which also increases the safety of personnel when operating the lighting tower.

Linings (9) are shaped steel sheets and are located above and below the hollow frame (8) with the formation of four corners of the frame (1) in such a way that 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 execution of the frame (1) in this way allows the use of folding outriggers (7) in the construction of the lighting tower, the length of which can be equal to the length of the frame (1) and at the same time completely fold into the transport position without protruding parts. This greatly increases the support contour of the light tower and therefore increases its stability during operation, reducing the risk of tipping over, while achieving a smooth compact contour for transportation, allowing the light tower to be unloaded and loaded into a vehicle easily and safely.

A through hole (14) is made in the corner of each lining (9) to install an axle for attaching the outrigger (15).

Outriggers (7) are installed on the axles for fastening the outriggers (15), holding the lighting mast in the working position.

Each outrigger (7) contains a spring retainer (16) and a jack (17).

The spring retainer (16) is shown in FIG. 5, is a spring-loaded, hardened cylindrical pin on one side and is designed for automatic fixation of the outrigger (7) in the extreme extended position.

Spring clips (16) protect the lighting tower from unauthorized folding of the outriggers (7) during operation, which can lead to loss of stability and overturning of the lighting tower.

The jack, shown in section in Fig. 6 is designed to install the product in a horizontal position even in areas with a pronounced surface roughness and contains a sleeve (18) of square section with a cover (19) and a base (20). As seen in FIG. 6, inside the sleeve (18) a square rod (22) connected to the ball bearing (23) is installed through anti-friction round-section bushings (21). A screw (25) is installed inside the square stem (22) through the bushing (24). The cover (19) of the jack (17) contains a through hole for the screw (25) to come out.

The use of a sleeve (18) of square section in the design of the jack (17), as well as a square rod (22) (i.e. a square rod) allows you to increase the axial moment of resistance of this section, which increases the local stability of the frame and the lighting mast as a whole.

The transfer of all four outriggers (7) to the working position is carried out by means of one removable handle. Thus, the outriggers (7), in contrast to known analogues, including the prototype, do not have protruding parts in the form of handles, and the risk of injury to personnel on the protruding parts of the lighting mast is reduced, thereby increasing the safety of its use.

At the same time, it is preferable that the frame (1) be made of 09G2S steel with a frame tube wall thickness of at least 3 mm, a lining thickness of at least 4 mm, and a reinforcing solid sheet (11) of at least 8 mm thick, which increases the stability of the frame during operation. in extended ranges of performance, since 09G2S steel is less prone to cracking in welds during sudden temperature changes (below 35 degrees) compared to others.

Similarly, it is preferable that the outriggers and side braces of the lighting mast be made of steel 09G2S.

The telescoping type mobile light tower may include a swing assembly or a lifting eye for loading and unloading the light tower to and from a vehicle, which will be described in more detail below.

Inside the hollow frame (8) of the frame (1), a telescopic boom (3) is installed between the square tubes, designed to raise the lighting crown (4) to a predetermined height.

The telescopic boom (3) consists of a stationary (fixed) part (26), which includes one fixed section (profile), and a movable part (27), which includes several movable sections (profiles), interconnected from above and below by roller blocks that provide movement sections (profiles) relative to each other. The movement of the telescopic boom (3) from the drive (6) is carried out through a block-chain system of reverse pulley blocks.

The design of the telescopic boom (3) is shown in more detail in figures 7-10.

The telescopic boom (3) consists of sections of the same type in terms of design (one section includes one profile). The movable part of the telescopic boom (27) can be equipped with a different number of sections, depending on the required lifting height of the lighting crown (4), for example, it can include 2, 4, 6 or 8 sections (profiles).

In this case, the first section of the movable part of the telescopic boom (27) is configured to locate the lead screw (54) of the drive (6) of the lighting mast inside it. In addition, a nut (55) is attached to the lower part of the first section of the movable part of the telescopic boom (27).

Each section of the telescopic boom (3) is connected by two parallel branches of chains (28) to the section standing in front of the previous section using holders (29), tensioners (30) and blocks (31) (for example: the third section is connected to the first; the fourth section is connected from the second, etc.).

Holders (29) are fixed directly on top of each section on the side surface of the telescopic boom (3), tensioners (30) are fixed on bars (32) installed at the bottom of each section of the movable part of the telescopic boom (27), and blocks (31) are mounted on axles from above on the end surface of each section of the movable part of the telescopic boom (27).

Thus, the block-chain movement system consists of two parallel branches of the chain (28) coming out of the holders (29), passing through the blocks (31) and entering the tensioners (30).

On the side surfaces of the sections (profiles) there are roller blocks (not shown), which are a housing with rollers, with the help of which one section moves along the other, in contact with it.

On the fixed section of the telescopic boom (3), a lifting eye (14) is fixed from above, made of sheet metal and allowing transportation of the lighting mast using a crane or overhead crane.

It is allowed to use a crane or overhead crane with a minimum lifting capacity of 1000 kg in conditions where it is necessary to transport the light tower over a short distance, but the conditions do not allow this to be done using the wheelbase (2). In this case, the load hook of the crane or crane beam must be fixed to the lifting eye (14) of the lighting mast.

A distinctive feature of the claimed invention is the location in the groove of the stationary part (26) of the telescopic boom (3) from below (closer to the frame) of the sensor for controlling the tilt angle of the telescopic boom (34), designed to determine the safe angles for using the telescopic boom at different heights. In case of exceeding the permissible tilt angle, the tilt angle control sensor (34) transmits this information to the controller, which in turn will block the possibility of lifting the telescopic boom up (with the corresponding sound signal).

An inclination sensor based on a solid-state accelerometer can be used as a tilt angle control sensor (34).

Location of the telescopic boom angle control sensor (34) in the slot of the stationary part of the telescopic boom (26) ensures smoothness and evenness of the surface of the telescopic boom (3), on which the mobile lighting mast can be placed during transportation, and therefore it will not interfere when unloading and loading the lighting tower into a transportation vehicle, and will not damage the stability of the lighting tower during transportation.

The use of a tilt angle control sensor (34) in the design of the lighting tower makes it possible to eliminate the possibility of the telescopic boom (3) exceeding the allowable angle of inclination to the vertical position, as a result of which the lighting tower can be overturned, thereby reducing the risk of injuries and other accidents and increasing safety .

The controller (not shown in the figure) is a safety device and is designed to be installed on the lighting tower in order to prevent its destruction and tipping over when the lighting crown (4) is lowered/raised, as well as to control the light alarm in critical operating modes of the lighting tower.

The controller that limits the tilt angle of the telescopic boom (3) contains a display and is placed in a housing with cable entries to supply power to it and receive information from the tilt angle sensor (34).

The principle of operation of the controller is based on receiving and converting an analog signal from the telescopic boom angle control sensor (34) and comparing the information received with the maximum permissible values.

To turn on signaling devices, an executive electromechanical relay with a contact group of the "dry contact" type is used.

The sensor operation algorithm is to transmit information directly to the controller, after which the controller evaluates the possibility of raising or lowering the telescopic boom (3) depending on the height of the illumination crown (4).

In a preferred embodiment of the invention, the telescopic boom (3) is made of 6082 T66 aluminum alloy. Due to the high yield strength of this alloy, the structure is able to withstand bending loads much higher than those made of aluminum or other aluminum alloy, which also increases the safety of using the light tower.

On the last section of the movable part of the telescopic boom (27) there is an illumination crown (4), shown in detail in FIG. 20-21.

The lighting crown (4) can be installed with the possibility of quick (quick, no additional tools required) removal.

The lighting crown (4) consists of a frame (33), brackets (35) and fixtures (36).

The frame of the lighting crown (33) is a rigid structure made of a shaped square tube and round tubes, as well as sheet metal, and is designed to accommodate a light source.

On the sides of the frame of the lighting crown (33) there are brackets (35) with the possibility of rotation relative to the frame (33) around the vertical axis through the rotary sleeve (71). Each bracket (35) is designed to hold two lamps (36). The design of the lighting crown (4) has four brackets (35), which allows you to install eight fixtures (36), in pairs for each.

Luminaires (36) consist of an aluminum profile, three LED voltage converting lenses, drivers and plastic plugs.

The illumination crown brackets (35) are shown in more detail in FIG. 20 and 21.

The bracket (35) is made of a lower bracket (37) and an upper bracket (38), connected to each other with the possibility of rotation relative to the horizontal axis. The brackets are made of sheet metal. Fixing the position of fixtures (36) is provided by the possibility of rotation of the upper bracket (38) relative to the lower bracket (37), as well as due to the rotation of the lower bracket (37) relative to the frame (33).

The lower bracket (37) is U-shaped, contains an end wall and side walls with rounded ends, additionally connected by a rigidity axis.

A swivel sleeve (71) is welded to the end wall of the bottom bracket (37), which secures the bottom bracket (37) to the frame of the lighting crown (33), which serves as the axis of rotation of the bracket (35) with the luminaires (36) around the vertical axis when adjusting the position of the luminaires (36).

Holes are made around the rotary sleeve (71) in the end wall of the bottom bracket (37) for fixing (72) the position of the bracket (35) with lamps (36) during operation or transportation of the lighting mast. Thus, the brackets (35) with luminaires (36) can be rotated around the vertical axis relative to the frame of the lighting crown (33) by 252° in 18° increments, which ensures the possibility of lighting in a wide range of angles, as well as obtaining an even compact contour. for transporting the lighting tower, which makes it easy and safe to unload and load the lighting tower into a vehicle without removing the lighting crown (4).

On each rounded end of the side walls of the lower bracket (37) there is a through hole for the axis of rigidity, a hole for connection with the upper bracket (38), as well as several adjustment holes (73) arranged in an arc to adjust the angle of the upper bracket (38) relative to the lower (37) (due to the possibility of rotation of the upper bracket (38) relative to the lower (37) around the horizontal axis).

The upper bracket (38) is made in the form of a frame with lugs, on which a reciprocal hole is made for connection with the bottom bracket (37) and a reciprocal adjustment hole (74) for adjusting the angle of inclination of the upper bracket (38) relative to the bottom one (37), corresponding to each of several adjustment holes (73) made on the bottom bracket (37).

Adjustment of the horizontal tilt angle of the luminaires (36) is carried out by aligning one of several adjustment holes (73) on the bottom bracket (37) with the mating adjustment hole (74) on the top bracket (38) and installing a fixing bolt into the specified adjustment holes, due to which it is possible to illuminate in a wide range of angles, as well as to obtain an even compact contour for transporting the lighting tower, which makes it easy and safe to unload and load the lighting tower into a vehicle without removing the lighting crown (4).

On the frame of the upper bracket (38) there are holes for fixing fixtures (36).

A wind speed sensor is installed on the frame of the lighting crown (33), (anemometer) (39) - a sensor that allows you to control the wind speed when the lighting mast is in operation, and a light beacon (40) - a beacon-type light indicator that provides light indication when movement of the lighting crown (4) up or down, as well as in the event of an emergency.

The wind speed sensor (39) and the light beacon (40) are connected to the controller. The algorithm of the sensors is to transmit information directly to the controller, after which the controller evaluates the possibility of raising or lowering the telescopic boom (3) depending on the height of the lighting crown (4), thereby increasing the automation of security control.

The lighting crown frame (33) has a panel (41) that provides access to the electrical communication system of the lighting tower located inside the frame (33).

The mechanism for fixing the illumination crown (4) on the telescopic boom (3) consists of a lower grip and an upper grip, which are illustrated in Fig. 14-16.

The locking mechanism is located on the front side of the last section of the movable part of the telescopic boom (27) in the center of the section. This arrangement does not require personnel to climb ladders, ladders or other means to work at height in order to mount and dismantle the lighting crown and increases the safety of using the lighting tower.

The bottom grip shown in Fig. 15 is a welded bottom bracket with hooks (42) for fixing one of the round tubes of the lighting crown frame (33).

The top grip shown in Fig. 16, consists of an upper bracket (43) with hooks, in the grooves (44) of which a hinged bracket (45) with a spring-loaded latch (46) is pivotally mounted by means of two axles (47).

The spring-loaded detent (46) includes a pedal (49) rigidly connected to the hinged bracket (45) and an extension spring (48).

The side rails of the hinged brace (45) contain recesses to wrap around one of the round tubes of the lighting crown frame (33). Thus, when fixing the lighting crown (4) in the upper grip, the round tube of the lighting crown frame (33) is located in the cavity formed by the hooks of the upper bracket (43) and the recesses of the folding bracket (45).

At the time of mounting the lighting crown (4) on the telescopic boom (3), the operator with an assistant lowers the round tubes of the lighting crown frame (33) onto the lower and upper grips, respectively, while the folding bracket (45) is in the upper position at this time and the extension spring (48) is fully compressed.

When the crown frame (33) is lowered, its round top tube rests on the pedal (49). As it is lowered, the pedal (49) rotates the folding bracket (45) relative to two axes (47) until the spring-loaded pin mechanism automatically operates on the spring retainer (46), which additionally fixes the folding bracket (45) relative to the upper bracket (43) (at this moment, the lighting crown (4) is fully fixed on the telescopic boom (3) of the lighting mast).

The presence of lower and upper grips designed for quick removal of the lighting crown (4) in the specified design makes it possible to reduce the weight of the lighting mast and lower its center of gravity for manual loading into a vehicle, which minimizes the risk of injury and thereby increases the safety of using the lighting mast, and also simplifies and increases the speed of preparatory and repair operations.

To dismantle the lighting crown (4), it is necessary to move the lever of the spring lock (46) and lift the lighting crown frame (33) up - in this case, the extension spring (48) will “release” the lighting crown frame (33) from the folding bracket (45).

Eyelets (50) are located on the hollow frame (8) of the frame (1) for attaching side braces (5) to the frame (1). On the other hand, the side braces (5) are rigidly fixed to the upper point of the stationary part of the telescopic boom (26) through the bracket so that the side braces (5) are not parallel to each other and form a spatial tetrahedron.

The implementation of the side braces (5) non-parallel (converging) provides greater rigidity of the boom with lateral gusts of wind. The fastening of the side braces (5) at the highest point of the stationary part of the telescopic boom (26) through the bracket “transfers” the dangerous section from the lower section of the stationary part of the stationary telescopic boom from any bending moments to the more rigid movable part of the telescopic boom (27). This design solution allows the telescopic boom (3) to perceive serious wind loads even at a height of 10-12 meters from the frame (1) without deviating from the vertical axis, which reduces the risk of injury or other accidents from the possibility of overturning the lighting mast and increases the safety of using the lighting mast during work.

On the frame (1) of the lighting mast, a telescopic boom motion drive (6) is installed, shown in Fig. 4 and 10. The movement drive of the telescopic boom (6) consists of a DC motor (51), a worm gear (52), a thrust cup with a bearing (53), a lead screw (54) and a nut (55), while the DC motor (51) and the worm gearbox (52) are fixed to the power solid sheet (11) of the frame (1) from below, and the thrust cup (53) - from above. The lead screw (54) is located in front of the fixed part of the telescopic boom inside the first section of the movable part of the telescopic boom, which is attached to its threaded part through the nut (55) mounted on it, fixed in the thrust cup (53) with a bearing and connected to the worm gear ( 52) via keyed connection. Due to these design solutions, the center of mass of the frame (1) is shifted as low as possible to the ground, which increases the stability of the lighting tower. At the same time, these design solutions make it possible to distribute the entire load from the lead screw (54) to the frame (1) evenly, removing all axial loads on the engine and gearbox, which increases their service life.

The use of this drive (6) for extending the telescopic boom (3) instead of the hydraulic system used in the prototype makes it possible not to install an additional oil station with a pump unit. Also, an electric drive has higher efficiency values than a hydraulic one.

When using an oil station, there is a possibility of polluting the atmosphere and personnel in case of normal operation of the safety valve or in the event of an abnormal breakdown of any elements of the hydraulic system (this also entails possible unauthorized lowering of the lighting mast down).

In the case of an electric screw drive, unauthorized lowering does not occur, since even in the event of a breakdown of the electric motor or gearbox, the bronze nut (55) will not slide over the screw (54) (self-braking occurs due to friction forces in the screw-nut pair), which is significant enhances security.

In one of the preferred embodiments of the invention, the claimed telescopic-type mobile lighting tower must be equipped with a turning unit designed to transfer the lighting tower from the working position to the transport position and vice versa, as well as loading the lighting tower into various trucks by applying force to the lever.

The turning point is shown in Fig. 11, 12 and consists of a U-shaped flip lever (56), a wheel block (57), a thrust block (58), a latch (59) and skis (60).

The U-shaped flip arm (56) is telescopically installed in the hollow frame (8) of the frame (1) of the lighting tower and is pulled out only when it is necessary to flip the lighting tower into the vehicle.

The U-shaped toggle lever (56) consists of two shaped square tubes interconnected by a round handle, which ensures the application of force to two points of the lighting mast frame, reduces the risk of the lighting mast tipping over when loaded into a vehicle, i.e. eliminates the risk of injury to personnel and increases the safety of work when loading the lighting tower into a vehicle. In addition, this shape of the reversing arm makes it possible for two workers to lift the lighting mast into the vehicle at the same time, which facilitates and simplifies the loading operation.

The implementation of the U-shaped flip lever (56) as a telescopic one eliminates the risk of injury to personnel when working on the protruding parts of the lighting mast.

The wheel block (57) is intended for rolling the lighting mast into a cargo vehicle after turning it over into the transport position. The wheel block (57) is rigidly mounted in the upper part of the stationary part of the telescopic boom (26) and consists of a welded frame and two wheels similar to the wheelbase (2).

Skis (60) are designed to slide the frame (1) over the vehicle body when loading the lighting mast. Skis (60) are rigidly mounted on the rear side of the frame (1) near the front wheels of the wheelbase (2). Skis (60) are a bent profile coated with an anti-friction coating.

The thrust block (58) is designed to ensure contact between the lighting tower and the vehicle when loading and unloading the lighting tower from the vehicle and has the ability to move vertically along the stationary part of the telescopic boom (26). However, its movement is limited from below by the frame (1), and from above by the latch (59).

The thrust block (58), shown in more detail in Fig.12, consists of two sidewalls (61), which move along the stationary part of the telescopic boom (26) using wheels (not shown), struts (62) connecting the sidewalls to each other, a scraper (63) installed in the sidewalls (61) with the help of the scraper axle (64).

Thus, the thrust block (58) is a structure that, on the one hand, is rigidly fixed to the stationary part of the telescopic boom (26) and at the same time has an element that is movable relative to the truck body - a scraper (63) on the axis of the scraper (64), which ensures the contact of the thrust block (58) and the truck body at one point both during loading and unloading of the lighting tower from the vehicle, i.e. ensures the unloading of the lighting mast without the application of additional force by the personnel (“jerking on themselves”), which minimizes the risk of injury during preparatory operations. In addition, this design of the thrust block (58) eliminates the possibility of interference with the scraper (63) when advancing the lighting tower along the floor of the body during loading, which also eliminates the need for personnel to apply additional force (“jerking away from themselves”), minimizes the risk of injury, and additionally simplifies and speeds up the preparatory operations.

The thrust block (58) is connected to the latch (59) with a hinged hook (65).

The latch (59) as well as the thrust block (58) has the ability to move vertically along the stationary part of the telescopic boom (26). The latch (59) is designed to set the thrust block (58) to the required height when loading (depending on the height of the vehicle) and to limit the movement of the thrust block (58) up the telescopic boom (3).

The retainer (59) consists of a clip (66) and a spring-loaded pin (67).

The bracket (66) is installed on the stationary part of the telescopic boom (26) with the help of antifriction elements and has the ability to move vertically relative to it.

To fix the thrust block (58) and the latch (59) at the required height, a bar (68) with through holes is provided on the stationary part of the telescopic boom (26).

When setting the loading height, the operator installs a spring-loaded pin (67) in one of the holes of the bar (68) rigidly fixed to the profile (depending on the specific loading height in the vehicle).

To facilitate the preparatory work, the lighting mast can be lifted with a forklift. In order to engage the lighting tower with the forklift, the hollow frame (8) of the frame (1) is provided with counter holes for the forklift forks (69), the shape of which corresponds to the shape of the forklift. The implementation of counter holes for the forks of the loader (69) in the frame (1) of the lighting mast increases the safety of using the lighting mast during preparatory operations in comparison with the scheme used in analogues for lifting with forks "under the frame" of the installation.

The invention works as follows.

Preparatory operations: loading of the declared mobile telescopic lighting tower into and out of a freight vehicle.

The process of loading the claimed lighting tower into the body of the vehicle is shown in Fig.17-19.

In order to carry out transportation to the object, the lighting mast is installed near the vehicle in the loading area, as shown in Fig. 17. The telescopic boom (3) of the lighting mast is lowered, the outriggers (7) are folded, the brackets (35) with lamps (36) are turned towards the telescopic boom (3) and fixed. The lighting tower is in the transport position.

By means of a spring-loaded pin (67), the thrust block (58) is set slightly above the vehicle loading height.

From the hollow body (8) of the frame (1) of the lighting mast, the worker extends the reversing lever (56) and, by applying force on it, tilts the lighting mast into the cargo area until the scraper (63) comes into contact with the floor of the cargo space. At this moment, the thrust block (58) moves up along the stationary part of the telescopic boom (26) until it comes into contact with the latch (59).

With further force on the reversing arm (56), the light mast tilts into the cargo area until the wheel block (57) comes into contact with the floor of the cargo area. At this moment, the folding hook (65) under its own weight releases the thrust block (58) from engagement with the latch (59). The swing arm (56) slides under its own weight into the hollow frame (8) of the frame (1).

Next, the operator rolls the lighting mast into the cargo area, pushing it forward. At the moment, the lighting tower rests only on the wheel block (57) and on the wheels of the thrust block (58), while the edge of the skis (60) rests against the outer side of the loading area.

Next, the operator rolls the lighting mast inward along the skis (60) until the front wheels of the wheelbase (2) come into contact with the floor of the loading area, for further rolling the product into the vehicle and transportation.

The design of the turning unit allows to increase safety and, at the same time, to simplify and speed up the loading of the claimed lighting tower into the vehicle.

When the lighting tower is delivered to the facility, it is unloaded from the vehicle, which is carried out in the same way in reverse order.

If necessary, a forklift can be used during the preparatory work. In this case, the loader's forks are installed in the mating holes (69) of the hollow frame (8) of the frame (1) of the lighting tower, and the lighting tower is lifted by the loader.

When the lighting tower is unloaded from the vehicle, it is manually transported by means of the wheelbase (2) to the specified work site.

Next, the lighting mast is installed in the working position. The operator opens the folding outriggers (7) until the spring lock (16) is activated and fixes them with jacks (17), for which he uses one removable handle.

Next, the operator installs the fixtures (36) of the lighting crown (4) in the required position by rotating the bracket (35) relative to the frame of the lighting crown (33) and installing in at least one hole for fixing (72) the bolt, as well as combining one of the many adjusting holes (73) on the bottom bracket (37) with a matching adjustment hole (74) on the top bracket (38) and installing a fixing bolt in them.

Control:

The lighting mast is controlled by the control panel (70) located on the telescopic boom (3). The control panel (70) contains a display on which are located:

• emergency stop button,

• work permission indicator,

• indicator of work prohibition,

• remote control activation lock,

• button "ON AND OFF THE LOWER LIGHTS",

• button "TURN ON AND OFF THE TOP LIGHTS",

• DOWN button,

• "LOCK" button,

• UP button.

The controller is located in the control panel (70).

The operation of the lighting tower is carried out from a single-phase network 230 V / 50 Hz with grounding.

The movement of the telescopic boom (3) is carried out when the drive (6) is turned on by pressing the corresponding button on the control panel (70). The lead screw (54) of the drive (6) drives the bronze nut (55) installed at the bottom of the first section of the movable part of the telescopic boom (27), thereby raising and lowering the movable part of the telescopic boom (27), the sections of which are interconnected by a block -chain system, relative to the stationary part (26).

When the telescopic boom (3) moves, the wind speed sensor (anemometer) (39) registers the wind speed and sends this information to the controller, which compares the information received with the maximum allowable values stored in its memory. If the permissible values are exceeded, the controller prohibits the movement of the telescopic boom (3) upwards. If the telescopic boom (3) is open, then when the permissible wind load is exceeded, the controller automatically lowers the lighting crown (4) in order to prevent possible tipping. (this is accompanied by a special sound signal).

When the telescopic boom (3) moves, the inclination angle control sensor (34) registers the value of two frame inclination angles to the horizon (along the “X” axis and along the “Y” axis) and sends this information to the controller, which compares the received information with the maximum allowable values stored in its memory. If one of the angles is exceeded, the controller prohibits the movement of the telescopic boom (3) only upwards (in this case, a special sound accompaniment occurs in such a situation). If the lighting crown (4) is already at a height and the controller starts to register slight deviations in the angles of inclination (for example, when the ground subsides): an audible warning occurs and after that the telescopic boom (3) of the lighting mast automatically lowers - to prevent tipping and security. Further lifting of the telescopic boom (3) is possible only when the tilt angles are restored to no more than permissible values.

The lighting mast is switched to the transport position by folding the telescopic boom (3), folding the outriggers (7) and removing the lighting crown (4) (if necessary) from the telescopic boom (3) or turning the brackets (35) with the lamps to the inside, according to towards the telescopic boom (3).

The claimed invention provides a reduction in the risk of injuries and other accidents when using a mobile telescopic lighting tower in extended performance, including preparatory operations and transportation, due to:

- improving the reliability of the lighting tower by increasing the stability of the lighting tower when performing work in advanced performance indicators, namely, reducing the center of gravity of the telescopic boom and frame, increasing the support contour of the lighting tower, increasing the rigidity of the telescopic boom, increasing the axial moment of resistance of the outrigger jack section,

- improving the reliability of the lighting mast units, such as the drive and outrigger jacks,

- elimination of traumatic operations to prepare equipment for operation or transportation, namely, reducing the risk of overturning and falling of the lighting mast when it is loaded into a vehicle, eliminating the change in the point of contact of the lighting mast with the floor of the vehicle when loading and unloading the lighting mast, ensuring uniform movement of the lighting mast when loading and unloading from a vehicle (eliminating the application of jerks “toward” or “away from you”), providing the possibility of reducing the weight of the lighting mast for loading and unloading,

- reducing the number of protruding parts,

- provision of specially designated storage areas for tools and personal belongings of the operator,

- automation of safety control in terms of automatic fixation of outriggers from unintentional folding during operation, control of the position (tilt angle) of the telescopic boom, control of wind load, both when moving up and when moving down.

Thus, the claimed mobile telescopic lighting tower in the above embodiments of the invention is designed for safe operation in open spaces and indoors with an ambient temperature of -45°C to +40°C and a relative humidity of not more than 80%, with the possibility of lifting to a height of up to 11 m and with wind gusts up to 12.5 m/s.
