Description

The utility model relates to the field of control and calibration of scales and can be used as part of weighing laboratories, especially for checking stationary platform electromechanical scales, mainly designed for weighing heavy weighed goods stacked by hoisting mechanisms, in particular, for performing metrological verification of gauge automobile scales, located at a considerable distance from the center of metrology.

A load-lifting device on a car-van is known, containing rail beams installed in the upper part of the van, a drive carriage with lifting ropes movably mounted in the longitudinal direction, and a grip made in the form of a traverse suspended on ropes and hooks installed on it (see, e.g. ., Auth. Certificate of the USSR No. 1382690, Mkl. 60 P 17/04).

Also known is the mobile weighing laboratory SPPL -2 of the Armavir Instrument-Making Plant TU 25-96, 1294-79. As part of this device there is a monorail protruding beyond the van, along which a load trolley is mixed.

Devices of a similar purpose are also known, containing two beams located under the ceiling of the van parallel and symmetrically with respect to the longitudinal axis of symmetry of the van of the van along which the load carriage moves (see, for example, Auth. St. USSR No. 261925 Mkl. 60 P 1/54, 1968 g.). To ensure the possibility of moving the carriage along one rail and the transition from rail to rail, a guide is provided, which, when the device is transferred to

the transport position must be retracted inside the van, (see, for example, RF patent No. 2031017 MKP. 60 P 1/54, application. 28.03.91). This device also has a disadvantage due to the fact that a large mass lifting device with a traction motor is suspended on the carriage, which leads to large loads on the suspension nodes when moving the car with the laboratory. In addition, the design of the introduced guide is very complex and not sufficiently reliable. It takes time to transfer the device to the working or transport position.

The closest to the proposed technical solution, according to the applicant, is a weighing complex according to the patent of the Russian Federation No. 2022833 Mcl B 60 P 1/54, decl. 09/06/90, containing a telpher beam installed parallel to the longitudinal axis of the van under the ceiling of the truck van, on which a trolley and tool holders mounted in the van under the telpher beam are mounted with the possibility of longitudinal movement. The design disadvantages, according to the applicant, are the lack of ease of use, since the beam is located along the longitudinal axis of symmetry of the van, so that the reference weights can be laid out only in one row, and also that the lifting device, including the traction motor, is located on the external end of console. This circumstance leads to the appearance of great efforts on the beam, which reduces the reliability and durability of the device. In addition, the location of the hoist under the monorail reduces the working clearance, i.e. the maximum hook lift above the floor of the van (container), the height of which is limited by the standards for the dimensions of vehicles. This does not allow sufficient use of the volume of the van for the transportation of reference weights. The location of the monorail in the plane of longitudinal symmetry of the van makes it difficult to install weights (weighing 500 -1000 kg) with a deviation from the longitudinal axis of symmetry of the load receiving platform on the ruts, lateral edges of the cargo receiving platform, which is necessary to verify the independence of the weighing from the position of the load on the cargo receiving platform, as well as checking gauge truck scales, which often do not have a continuous load-bearing platform under the longitudinal axis of the container. The location of the mechanism for moving the trolley cart on the trolley itself reduces

the reliability of moving the trolley trolley along the monorail, especially if a weight is suspended on the telpher and the monorail (container, van) is installed with a deviation from the horizontal plane, for example, due to unevenness of the supporting surface.

The aim of the invention is to simplify the design and increase the reliability of the device, as well as expanding the capabilities of operation.

For this purpose, in a weighing complex containing a monorail mounted parallel to the container’s longitudinal plane of symmetry under the ceiling of the container, a traction winch with a traction cable, a load gripping unit, a trolley mounted on a monorail with the possibility of longitudinal movement, a trolley moving mechanism, and lodgements installed in the container under monorail, introduced the second monorail, on which the second trolley is mounted with the possibility of longitudinal movement, and additional lodgements installed in the container span under the second monorail, the mechanism for moving the second carriage, the second traction winch with a traction cable, the second load gripping unit, two movable blocks, six fixed blocks, monorails are fixed symmetrically relative to the vertical longitudinal plane of symmetry of the container, on the front and rear sides of each carriage are fixed respectively the axis of two fixed blocks, on the back side of each monorail one fixed block is fixed, the load-gripping unit of each trolley is respectively fixed on the movable axis block, traction winches are fixed on the container body, the traction cable of each traction winch is respectively sequentially stored through a fixed block fixed on the rear side of the monorail, a fixed block fixed on the rear side of the trolley, a movable block, a fixed block fixed on the front side of the trolley and fixed on the front side of the corresponding monorail, the movement mechanism of each trolley contains an engine mounted on the rear side of the corresponding monorail and kinematically connected the box with the corresponding trolley, the blocks, the axis of the blocks are perpendicular to the longitudinal plane of symmetry of the container ..

The invention is illustrated by drawings, which show an example implementation of the proposed device. It should be noted that the implementation of the load gripping unit in the form of a hook, as well as the mechanism for moving the trolley in the form of a gear motor with a chain drive, is only a concrete example of the design.

Since the execution of the monorails and the carts located on them is identical, and the drawings of FIGS. 3 and 4 show sections of a transportable container, the drawings show the designations of the individual elements belonging to only one of the monorails, which, according to the applicant, facilitates the reading of the drawings and understanding of the proposed design .

The weighing and testing complex contains a movable container 2, mounted under the ceiling 1 (of a semi-trailer or a covered truck van) parallel to the longitudinal axis 3 of the container 2, a monorail 4, a traction winch 5 with a traction cable 6 and a load gripping unit 7, a trolley 8 is mounted with a longitudinal movement for monorail 4 , a second monorail 9 on which a second trolley is mounted, a second traction winch with a traction cable, and a second load gripping unit. (since the monorails 4 and 9 and the elements belonging to them have an identical construction, the elements related to the monorail are not indicated by 9 in the drawings to simplify the understanding of the device operation), the mechanism 10 for moving the carriage 8, the movable block 11, three stationary blocks 12, 13 , 14, the monorails 4 and 9 are fixed symmetrically with respect to the longitudinal plane of symmetry 15 of the container 2, the axes of two fixed blocks 12 and 13 are fixed on the front and rear sides of the cart 8, one fixed block is fixed on the rear side of the monorail 4 14, the load gripping unit 7 is fixed on the axis of the movable unit 11, the traction winch 5 is fixed on the floor 16 of the container 2, the traction cable 6 of the traction winch 5 is sequentially stored through the fixed unit 14, mounted on the rear side of the monorail 4, the fixed unit 13, mounted on the rear side trolleys 8, movable block 11, fixed block 12,

mounted on the front side of the carriage 8 and mounted on the front side of the monorail 4, the mechanism 10 for moving the carriage 8 includes an engine 17 mounted on the rear side of the monorail 4 and kinematically connected to the carriage 8 via a chain gear 18 with an asterisk 19. The position 20 indicates the weight of the weighing complex, lodges 21 for weights 20 are located under the corresponding monorails 4 and 9, the limit switches are indicated by positions 22 and 23, and the rollers providing movement of the trolley 8 along the monorail 4 are indicated by 24; For a complete idea of the specific constructive implementation of the complex in the housing of the transportable container 1, the drawings show the power generation system 24, control cabinet 25, bracket 26, on which the fixed unit 14 is fixed, brackets 27, 28 through which monorails 4 and 9 are attached to the ceiling 1 of container 2 The device operates as follows:

To load the weighing complex with reference test weights (weights 20), the trolley 8 is pushed out of the container 2 from the container 2 along the monorail 4 to the position shown in the drawings. Then, with the help of the traction winch 5, lower the hook 7, grab the weight (the weight outside the container is not shown in the drawings), lift the traction winch 5 on the hook 7. Using the mechanism 10, move the cart 8 along the monorail 4 into the depth of the container 2 and lower the weight 20 by the traction winch 5 to the right place in the cradle 21. The required weights are installed on the site of the calibrated scales in the reverse order. The movement of the trolley 8 is limited by limit switches 22 and 23. The movement of calibration weights from the transport position to the working one and vice versa using the second monorail 9 and its structural elements is carried out similarly. Thus, the proposed design of the device allows you to load more containers (weights) into the container, both by stacking them in two rows on the lodgements, and in a larger number of rows in height due to the greater clearance between the container floor and the hook.
