The disadvantages of the known device are: - the absence of additional compartments for various inventory;

[0010] - a design with a large number of articulated joints, which without bearings may not withstand heavy loads (wood, sand, soil, etc.), which ultimately increases the likelihood of device failure;

[0011] - small diameter of the front wheels, which leads to limited cross-country ability of the device on uneven surfaces and rough terrain (getting stuck in the ground, getting stuck in potholes) and to an increased likelihood of tipping over the loaded trolley when it is moved forward over the axle of the front wheels;

[0012] - low maneuverability of the device;

[0013] - the location of the drive mechanism on the frame, requiring additional wheel drive units.

[0014] A combined electric hand truck is known, formed in the form of a box and comprising: a folding cover on the upper surface, an auxiliary wheel on the lower surface in the area adjacent to the steering wheel, a signal lamp in the upper area of ​​the advertising display unit formed in front of the direction of movement of the motorized rear body of the car, so that the control unit operates in accordance with the user's control, the rear part of the car body with an electric drive, which issues a warning signal classified when stopping, using an LED module, thanks to the inclusion of a touch panel in the smartphone holder on the steering wheel, it not only controls the bidirectional change of the wheel mode with a battery-based in-wheel motor, but also a handle control unit that adjusts the length of the steering wheel by controlling hydraulic or pneumatic folding drive modules formed at both ends of the rod,where they come into contact with the rear electric drive of the car body (publication KR102369197, IPC B62B 1 / 12, B62B 5 / 00, B62B 5 / 06, B62B 5 / 08, G09F 21 / 04, 2022, 2022, https: / / patentscope.wipo.int / search / ru / detail.jsf?docId=KR356037093). The disadvantages of the known device are:,

[0015] - limited use only in the medical field for the transportation of goods, the movement of which is subject to certain requirements

[0016] - lack of additional compartments for various equipment;

[0017] - the presence of a large body, which increases the overall weight of the trolley and reduces the ground clearance, which leads to a decrease in the cross-country ability, mobility, maneuverability and controllability of the device; - the lack of the ability to vertically physically impact the handle by pressing to pass obstacles due to the presence of three wheels and a large body.

[0018] The closest in technical essence to the claimed invention is a trolley-post for a janitor with inventory, containing a tubular frame for installing a plastic tank, two side wheels, two side handles-handrails, two front stops, as well as tapes for fixing the installed plastic tank are attached to the frame (URL: https: / / ooo888.ru / shop / product / telezhka-post-dlya-dvomika, Date of access: 07 / 26 / 2023). The disadvantages of the known device are:

[0019] - lack of additional compartments for various equipment;

[0020] - the need for a person to apply physical effort to move the cart, which increases the labor intensity of using the device and the speed of its movement;

[0021] - the design of the handles-handrails, providing a small lever for applying force to move the trolley and requiring the mandatory use of both hands when operating;

[0022] - fixing the tank with tape, which increases the time it takes to install the tank and does not ensure sufficient reliability of its fastening.

[0023] - small wheel diameter, which limits the cross-country ability of the device on uneven surfaces and rough terrain (getting stuck in the ground, getting stuck in potholes);

[0024] - the location of the tool holder mount in which the attached tool makes it difficult to operate the device.

[0025] The objective of the claimed group of inventions is to eliminate the said disadvantages, and the technical result consists in increasing the speed, mobility, maneuverability and convenience of moving cargo through the use of cargo trolleys.

[0026] The specified technical result is achieved due to the fact that the cargo trolley consists of a tubular frame for installing a plastic tank, on the lower part of the sides of the tubular frame there are two leading side motor-wheels with spokes and with electric motors mounted in them, and the side motor-wheels are attached using adapter bushings put on the axle of each cantilever-type motor-wheel, fixing them in the eye, on the upper part of the rear side of the tubular frame there is a movable tubular retainer for attaching a plastic tank and a handle-handle, where the trolley controls are located: a gas handle, an on-board computer with an LED display and an on / off power switch, a brake handle for controlling the rim brakes, on the lower part of the front side of the tubular frame there is a trolley stop installed, also on the rear side of the tubular frame there are tubular niches for placing inventory,between which there is a box with controllers and a battery.

[0027] Another embodiment of the invention assumes that the cargo trolley consists of a tubular frame for installing a plastic tank, on the lower part of the sides of the tubular frame there are two leading side motor-wheels with spokes and with electric motors mounted therein, wherein the side motor-wheels are attached using adapter bushings put on the axle of each cantilever-type motor-wheel, fixing them in the eye, on the upper part of the rear side of the tubular frame there is a movable tubular retainer for attaching a plastic tank and a handle-handle, where the trolley control elements are located: a gas handle, an on-board computer with an LED display and an on / off power switch, a brake handle for controlling the rim brakes, on the lower part of the front side of the tubular frame there is a trolley stop installed, also on the rear side of the tubular frame there are mounted tubular niches for placing inventory,between which is located a box with controllers and a battery, while in the tubular niches one or more of the following devices, powered from the battery through a voltage-reducing device, are installed: a blower, a vacuum cleaner, a broom, a grass trimmer, a scythe, a brush cutter, a sprayer, a cultivator.

[0028] The use of two leading side motor wheels with spokes, the electric motors of which are driven by energy from the battery by pressing the gas handle, makes it easy to control a cargo trolley loaded not only with cleaning equipment, but also with a fully filled tank, which is securely fastened with a movably installed tubular retainer. The use of large-diameter wheels increases the cross-country ability of the trolley on uneven surfaces, on stairs and over obstacles such as curbs, and also reduces the overall weight of the device. Fastening two leading side motor wheels with adapter bushings makes it possible to reduce the dimensions of the device compared to other fastening methods, for example, fork-mounted, which also increases the mobility and maneuverability of the claimed invention.In addition, the use of built-in electric motors that provide direct rotation of the motor wheels simplifies the design of the device due to the absence of a transmission through which it is necessary to transmit the force of movement. Installation in tubular niches powered by a battery through a device for reducing the voltage of devices allows not only to compactly place additional electrical equipment without negatively affecting the speed of movement and maneuverability of the claimed invention, but also to prevent premature shutdown of such equipment during its prolonged use.

[0029] To increase the strength of the device, the tubular frame is made of steel, aluminum or stainless steel pipes.

[0030] For optimal operation of the device, it is recommended to select values ​​for various technical characteristics from the following range:

[0031] - dimensions of the tubular frame: length 400-1000 mm, width 300-1000 mm, height 400-1000 mm;

[0032] - diameter of motor wheels 16-29 inches;

[0033] - dimensions of the handle-handrail: length 400-1200 mm and width 300-1000 mm.

[0034] - the power of the electric motor on each motor wheel is 200-500 W.

[0035] To improve the ease of use of the device, the trolley control elements can be supplemented by installing one and / or several of the following devices on the handlebar: a tracker, a movement control button, a mechanical throttle limiter, a reverse button, a smart speaker with voice control of the audio system.

[0036] To increase the safety of using the device, it is advisable to attach reflective tape around the perimeter of the tubular frame.

[0037] The device can also be supplemented with other accessories depending on the user's needs, for example, by installing a removable holder for garbage bags on the tubular frame.

[0038] The claimed invention is illustrated in Fig. 1 and Fig. 2, which show a side view and a top view of a cargo trolley with an air blower, respectively, using the following designations:

[0039] 1 - tubular frame;

[0040] 2 - side motor wheel;

[0041] 3 - handle-handrail;

[0042] 4 - throttle handle;

[0043] 5 - brake handle;

[0044] 6 - on-board computer with LED display;

[0045] 7 - power on / off switch; 8 - stop;

[0046] 9 - plastic tank;

[0047] 10 - tubular retainer;

[0048] 11 - tubular niches;

[0049] 12 - battery compartment;

[0050] 13 - rim brake,

[0051] 14 - blower.

[0052] The cargo trolley is a tubular frame 1 with dimensions selected from the following ranges: length 400-1000 mm, width 300-1000 mm, height 400-1000 mm. On the lower part of the sides of the tubular frame 1 there are two leading side motor wheels 2 with spokes and with electric motors mounted in them, and the side motor wheels are attached using adapter bushings placed on the axle of each cantilever-type motor wheel, fixing them in the eye. On the upper part of the rear side of the tubular frame 1 there is a movable tubular retainer 10, which secures by its lowering a plastic tank 9 installed inside the tubular frame 1, and a handrail handle 3, where the trolley control elements are located: a gas handle 4, a brake handle 5 for controlling the rim brakes 13, an on-board computer with an LED display 6 and a power on / off switch 7.On the lower part of the front side of the tubular frame 1, a stop 8 is installed, due to which the device is stable during downtime and does not roll away on its own. Also on the rear side of the tubular frame 1, tubular niches 11 are mounted for placing inventory (tongs for waste, a broom, a shovel, a rake, etc.), behind which a controller and a compartment with a battery 12 are installed.

[0053] Before using the cargo trolley, a plastic tank 9 is installed inside the tubular frame 1, and the necessary inventory is placed in the tubular niches 11. For example, an air blower 14 is installed in one of the tubular niches 11, which is connected via a flexible cable to the battery 12 through a voltage-reducing device. During operation, the air blower branch pipe 14 is directed so that the air flow blows leaves and small debris in the desired direction, and the air blower can operate when connected to the battery 12 or independently after charging its own battery. To set the device in motion, it is necessary to move the power on / off switch 7 to the "on" position and press the gas handle 4. Two leading side motor wheels 2 are set in motion by electric motors mounted in them, powered by the battery 12.The user only needs to walk alongside and guide the cargo trolley without applying any physical effort. At the same time, the on-board computer with LED display 6 displays the battery charge level, speed and other indicators of the cargo trolley. To stop the device from moving, it is necessary to press the brake handle 5 located on the handrail handle 3, which tightens the cable that sets the rim brakes 13 in motion, clamping the rims of the side motor wheels 2. Another braking option involves releasing the gas handle 4, which stops the power supply to the electric motors and the rotation of the side motor wheels 2, with the simultaneous use of the user's muscular strength.

[0054] Thus, the technical result of the claimed invention consists in increasing the speed, mobility, maneuverability and convenience of moving cargo through the use of cargo trolleys.
