Description

The technical field to which the invention relates

The invention relates to vehicles for the transport of goods, in particular, to a transport trolley with a self-propelled towing vehicle and can be used in loading and unloading operations, for transporting goods of any type in a warehouse or production, at an airport or train station, and transportation in vehicles for various purposes.

State of the art

Known rigging roller bogie with 4 fixed rollers for moving medium-heavy loads with a carrying capacity of 1000 kg (see rigging roller bogie YALELF-1 (Germany), www. Kiit. Ru, innovation and technology company).

The disadvantage of this trolley is its low reliability.

A vehicle for the transportation of long loads is known, including a trolley and a frame with end and supra-trolley beams and end parts with side braces attached to them, as well as a device for supporting a load, and each device for supporting a load is made with the ability to roll in the longitudinal direction, for example , in the form of a roller located parallel to the bogie beam in V-shaped brackets fixed on the frame, and the end parts are made in the form of pallets with end walls, each of which rests on the end beam with the help of supports, elastically connected to the frame in the longitudinal direction using a damping device and is installed with the possibility of contact with the backstops.

In a vehicle, a damping device is made in the form of several horizontal springs symmetrically located relative to the longitudinal axis of the frame, installed on pipes rigidly fixed to the end beams, equipped with adjusting screws located inside the pipes and abutting on one side against the brackets fixed on the pallets from below, and on the other - into the end beam.

In a vehicle, the backstops are the mentioned V-shaped brackets (see US Pat. RU No. 2156197, IPC B61D 3/16, B61P 3/40, publ. 09/20/2000).

The disadvantage of this vehicle is the complexity of the design, low reliability.

Known hand trolley for transporting cargo, including a frame formed by support legs with wheels, a platform, a lifting mechanism and a pallet, while the lifting mechanism is mounted on the platform and can be made in the form of a screw pair, a winch or a hand hoist, and on the frame between with wheels of racks and a platform, a removable horizontally located pallet is installed, which is made in the form of a metal lattice, separate metal brackets or in the form of a wooden shield (see US Pat. RU No. 2491200, IPC В62В 3/04, В66F 9/06, publ. 08.06.2011 g.).

The disadvantage of this hand trolley for transporting goods is the complexity of the design, low reliability, limited functionality, namely, the movement of goods only over short distances, as well as the impossibility of loading the cargo with the trolley into vehicles.

The closest in technical essence and the achieved positive effect and adopted by the authors as a prototype is a heavy-duty frame hand trolley for transportation of goods of any type, with a carrying capacity of 3 tons, without flooring and sides, with pneumatic wheels with a diameter of 450 or 540 mm or with cast rubber wheels with a diameter of 375 mm, the front axle is on a support bearing, and the swivel drawbar has a 180-degree angle of rotation, in the rear part there is a tow hitch (hitch), and the absence of flooring and sides maximally simplifies and reduces the cost of the design, while the trolley contains a frame with wheels, an extension for the frame , in the form of cross beams, swivel arm, suspension and swivel mechanism of the wheel, (see. Heavy-duty frame trolley RUSKLAD BT 2K 1250 × 2500 mm, carrying capacity 3000 kg. Catalog RUSKLAD platform trolleys of Russian production).

The disadvantage of this trolley is that it is easy to transport vehicles for loading and unloading operations, since large human and technical resources are required to perform these works.

Disclosure of invention

The objective of the present invention is the development of a transport carriage, which has a reduction in the downtime of vehicles for loading and unloading operations, as well as a decrease in the necessary human and technical resources required to perform these works.

The technical result, which can be obtained with the help of the present invention, comes down to reducing the downtime of vehicles for loading and unloading operations and reducing the necessary human and technical resources to perform these works.

The technical result is achieved with the help of a transport trolley containing a frame with wheels, an extension for the frame, in the form of cross beams, a swing arm, a suspension, a swing mechanism of the wheel, while it is equipped with a manual towing vehicle, and the frame is equipped with docking and locking ears, rods, and on docking ears are rigidly fixed to the frame from the front and rear parts, and the locking ears are fixed to the front part of the frame with the possibility of a parking brake in the vehicle, while on both sides inside the frame there are forks and a suspension made independent and pivotally connected to the frame using a pivot axis the fork mechanism, while under the rear end of the independent suspension fork there is an independent suspension spring, the lower part of which rests against the lower limit bar rigidly fixed to the lower part of the frame, and the upper support bar is rigidly fixed to support the spring, while rigidly fixed to the independent suspension fork using bolts on a gate mechanism, consisting of an outer body, inside which there is a pivot body with an axis of the pivot mechanism, on which the bearing of the outer body is located, and on the lower part of the pivot mechanism, a support bearing is installed, abutting against the bottom of the outer body, and the outer body of the pivot mechanism is locked with using a retaining ring, and wheels are installed inside the rotary housing, with bearings, while the wheel axle is locked by a retaining ring, and a pivot rod lever with a rod fastening finger attached to it is installed on the axis of the rotary mechanism, while the fastening pin is connected to the rod, the second end of the rod connected to the lugs of the traction and attached to the pivot arm, which is attached to the frame with the lugs of the pivot arm, while the latter is connected by means of a hook to a self-propelled towing vehicle, consisting of a frame, wheels with a wheel axle, on which an electric motor with a gearbox with a small sprocket and a chain transfer to a large asterisk p of the emitter, while to the front of the frame of the self-propelled towing vehicle, a hook connected to the pivot arm is rigidly fixed.

Thus, the technical result is achieved due to a transport trolley with a self-propelled towing vehicle, which includes a swivel wheel mechanism, an independent suspension for each wheel, which are installed inside the swivel housing, as well as a swivel arm, docking lugs, locking lugs, swivel rods, a rod arm, a locking ring wheel axle, additional for the frame and transportation using a self-propelled towing vehicle in loading and unloading operations and transportation of the trolley in a vehicle.
