Description

The present invention relates to weighing equipment, namely to weighting cars designed for calibration of car scales with a wide weighing range of one or two cars on the gauge railways of the Russian Federation, CIS countries, Latvia, Lithuania and Estonia.

The following solutions are known in the art.

A weight-verification complex is known that contains a car with a van mounted on a trailer, a set of model weights, a forklift transported by a car, a traction winch and a gangway in the form of inclined rails for loading and unloading a forklift (Patent RU 2019451 C 1, 09/15/1994).

Also known is a mobile device for checking weights by the method of applying weights, containing a vehicle with weights located on it, a rotary device and a ladder (РЖ N 10, 1975, Metrological and measuring equipment, p.42-46. - Metrological problems of checking weights).

The disadvantage of these devices is the presence of a loader for the transportation of weights, which does not make it possible to use this complex for checking carriage weights, the heavy weight of the complex due to the presence of a loader.

Also known is a weighing complex containing running bearings with a body, in the upper part of which a longitudinal guide is fixed for moving the trolley with running wheels and a lifting device, a set of weights that are installed in the body. (RU 2022833 C1, 11/15/1994).

The disadvantage of this design is the installation of the complex on a car chassis, which does not make it possible to effectively use it for calibration of carriage weights. The installation of weights on the lodges complicates maintenance, since for the accurate installation of weights on the scales only come with a hoist to manipulate. In addition, there are no means for fixing weights on the side of the end doors, which can lead to damage to the body during sudden braking during movement.

The closest analogue of the proposed technical solution is a weight-checking complex containing a body, in the upper part of which a longitudinal beam is fixed for moving the boom of the electric hoist with a gripper, a set of weights that are installed in the body. The body is mounted on a frame with railway trolleys and is equipped with self-propelled weight-checking trolleys mounted with the possibility of fixing, made with the possibility of placing and fixing weights on them, and the hinges of each end door are made with the possibility of turning the door by an angle of at least 270 °, and the body is made with the possibility of fixing doors in open and closed positions and is equipped with a means for fixing weights from the side of the front doors (patent RU53006U1, 04/27/2006). This device can be selected as a prototype.

The disadvantage of the analogue is that the boom and hoist are controlled only with the help of a control panel located in the cab mounted on the boom, with the cab glazing occupying no more than a third of the entire side surface of the cab, which entails a small viewing area from the cab and the impossibility of accurate positioning of metrological equipment by the operator. Also, the known complex does not provide mechanical protection for the lighting elements of the car, lifting and metrological equipment during the movement of the car and during unloading / loading operations.

The technical problem solved by the claimed complex is the need to modernize the production process, ensure safety for personnel and equipment, increase the accuracy of calibration of scales.

The technical result of the proposed technical solution is to increase the accuracy of the unloading / loading of metrological equipment during verification work with safety at the expense of improvements in terms of controlling the movement of the boom and hoist, as well as the mechanisms of lifting equipment.

The claimed technical result is achieved by the fact that the weighing complex includes a six-axle car with oar end gates and lighting with protective metal grills, and inside of which a two-tee boom boom with a retractable boom beam is welded to the roof stiffeners, on which the driver’s cab is fixed with side glazing surface component 0.4 ÷ 0.6 of the total surface of the front and side walls, electric hoist with a lifting capacity of 2.0 ÷ 4.0 tons, on which the automatic eskoe lifting devices moving the boom mechanism comprising two gear motor arranged according to FIG. 2 and the mechanism for moving the hoist, while the mechanisms for moving the boom and hoist are wired to the control panel on the hoist, as well as to the control module connected to the radio transmitter mounted on the boom, which is wirelessly connected to the control panel, including 1-2 joysticks, 4-12 buttons, while the boom is fixed during transportation of the complex by means of a mounting unit, including a lanyard and a loop put on the boom hook, at least one all-metal weight is located in the lower part of the car about the bracket in the middle, while the weight is placed on the base, which is a platform welded to the floor of the car, having conical protrusions corresponding to the conical grooves made in the lower part of the weight, and along the edges of the site are fencing with truss configurations welded to the side walls of the car , also in the lower part of the car are two weight control trolleys, each of which has a frame mounted on two wheel axles fixed in arc bearings-shoes welded to the car floor; on the car body in the upper part of which a longitudinal beam is fixed for moving the boom and electric hoist with an automatic load gripping device and a set of weights. In the particular case of the invention, the lighting means are LED lights mounted on the side walls of the car and having protection against mechanical damage in the form of metal gratings .

In the particular case of the invention, the lighting means include two emergency rechargeable LED lamps in the working part of the car, the batteries of which are charged when the diesel generator set is connected or the car is connected to an external 380 V network.

In the particular case of the invention, non-contact induction limit switches and mechanical stops are installed on the boom to limit the movement of the boom and hoist.

In the particular case of carrying out the invention, 39 all-metal weights (without inert fillers) of 2000 kg each and a basket with 50 weights of 20 kg each are placed in the lower part of the car.

In the particular case of the invention, each weight control trolley has a mass of 2000 kg, one of which is installed in the middle of the car, and the other near the swing end gates.

In the particular case of the invention, the boom during transportation of the complex is fixed by means of three attachment points.

In the particular case of the invention, two-ton weights are located on the installation floor of the car floor, each of which has two symmetrically located fitting recesses in the upper part, closed by a lid with a hole in the middle, in which the upper part of the bracket is located, the lower parts of which are mounted in the weight body, while the weights at the edges are secured with locking screws with locknuts, and the upper screws located closer to the swing gates have an elongated structure (330-350 cm), which provides reliable fastening upper weights and does not allow their transverse movement.

In addition to the wired control panel for the mechanisms of movement of the boom, hoist and lifting device, the proposed solution provides the ability to control the boom, hoist and automatic lifting device by the operator using a remote controller with joysticks and buttons. Due to the fact that in the case of controlling the remote control, the operator does not need to be in the cab, but it is possible to control the boom, hoist and automatic load gripping device outside the car (at a distance of up to 100 meters from the boom), the exact positioning of the load when lifting / moving / is ensured lowering / grabbing a kettlebell. The nodes of the crane move freely, their speed does not slow down, since the operator perfectly sees the surrounding area and is better oriented than when in the cab, and the operator can move around the facility and control the operation of lifting equipment from different positions. In addition, the smoothness and accuracy of the boom movement is provided by two gear motors, instead of one. Thus, the movement of cargo is carried out along an optimal trajectory, under the complete control of the operator. At the same time, safety for the operator outside the cab, as well as for the equipment itself, is ensured by increased hoisting capacity, protective metal grilles on LED lamps, which eliminates their accidental damage and the fall of lighting elements from mounts, including to the operator. The increased glazing of the driver's cab (0.4 ÷ 0.6 of the side surface in comparison with standard glazing up to 0.3) provides the best view for the operator of lifting equipment in case of need to work from the cab.

Further, the solution is illustrated by reference to the figures, which show the following.
