Description

The utility model relates to mechanical engineering, namely to assembly equipment and can be used for assembly, tipping (turning) and transportation of products.

The purpose of the utility model is to increase versatility by providing the possibility of use for products with various sizes.

State of the art

A trolley is known that comprises wheels supported by a cross member, supported by a cross member, mounted on the longitudinal beams of the rack, a beam that is rotatable in the longitudinal vertical plane, having a fastening unit for the goods to be transported, a beam of a beam, and also an additional beam with a drive locked with the drive of the first traverses, moreover, the longitudinal beams of the trolley frame are connected with the cross member with the possibility of changing the distance between them, and both drives are a jack fixed to the longitudinal beams . In addition, there is a blocking device for traverses that prevents them from turning when the load is loose (AS USSR No. 1062089, MKI B62V 3/04, 1982, publ. Bull. No. 47, 1983) [1].

When working with a trolley, using the drive, the longitudinal beams are moved, and the distance between them is adjusted to the size of a particular product.

In the initial position, with an unsecured product, the locking device does not allow the yoke to rotate. When fixing the product with standard bolts, they also unlock the turn of the traverse. Using the drive, the traverses with the product are rotated according to the specified pattern, perform the necessary assembly operations, then the traverses are returned to their original position and the product is removed, while the traverses are again blocked from rotation.

The well-known trolley allows you to fix, transport and turn over (turn) the product, but has the disadvantages:

- the inability to rotate the product 360 °, i.e. limited access to the product during assembly, due to the use of jacks (interlocked) among themselves, mounted on longitudinal beams and traverses, as a drive;

- the complexity of the design, due to the presence of two drives (jacks) and a mechanism for matching drives among themselves;

- the lack of fixing the position of the traverse with the product during assembly and tipping (turning) at any angle.

For the prototype, as the closest in technical essence to the claimed one, a trolley according to the RF Patent for utility model No. 81149, IPC BV 3/04, 2008, publ. 2009.03.10 [2].

The prototype trolley contains, based on wheels, longitudinal beams connected by cross members, mounted on the longitudinal beams of the rack, mounted on the latter, a rotary beam with holes for securing the cargo and a drive for turning it on one of the racks, while the said rotary beam is removable and with a sling element, and on the axis of its rotation a position lock is installed in the form of a disk with holes around the circumference, alternating with the hole in the said rack and the locking pin entering through the hole e in the rack in one of the holes on the disc when you turn the traverse.

The prototype trolley operates as follows:

- the product or its components are fixed on a rotary traverse;

- the product is assembled, while the traverse is unlocked and turned over (rotated) at various angles in the range of 360 ° for accessibility to components, including for electrical installation;

- all positions (including transport and working) are locked with a latch, while the locking pin enters one of the holes of the disk (depending on the angle of rotation) through the hole in one of the racks;

- transport the cart with the product on wheels to the points of adjustment, testing or packaging in an upright position, with the flange down (to reduce the center of mass point, and accordingly increase stability);

- translate the rotary traverse with the product in a vertical position, flange up (180 ° rotation, for access to rigging points on the product flange) using a drive;

- install a sling element (without interference) on the cross-arm (on the back side of the product fixing) and fix it on the hook of the load-lifting mechanism (crane, hoist, etc.);

- hang the beam with the product with a certain lift (with an interference fit) using a lifting mechanism;

- release the mounting of the rotary (it is also load gripping) traverse to the trolley, while the product is in a suspended state;

- they lift and move the product on the beam, freed from fastening to the cart, by means of a lifting mechanism;

- make installation of the product, for example in a device for mechanical testing or in a container of sealed containers and remove the traverse from the product.

The prototype trolley allows you to fasten, assemble, turn over (rotate) and transport products, but has the disadvantage of the inability to work with similar products of various sizes.

The purpose of the utility model is to increase versatility by providing the possibility of use for products with various sizes.

This goal is achieved by the fact that in the trolley-trolley, containing, supported by wheels, longitudinal beams connected by cross members, mounted on the longitudinal beams of the rack, mounted on the last rotary beam with a latch and a drive for turning the beam on one of the columns, the central beam is made in the said beam hole and installed slats with slots with the ability to move.

The technical result in the implementation of the utility model is to increase versatility, by ensuring the assembly, tipping (rotation) and transportation of similar products with different sizes.

Utility Model Disclosure

The problem to which the utility model is directed is as follows.

In the manufacture (assembly), adjustment, testing and transportation of units, blocks, etc. (hereinafter referred to as products) trolleys are used (tilter from Polish - kantować, from German kanten - turn over).

The tilting cart is a welded frame, at the bottom of which four rotary (self-mounted) wheels are installed. At the top of the frame there are two vertical racks with pins, in which a rotary traverse (platform) is installed for fixing the product with a position lock. On one of the racks there is a worm gear (drive), on the output shaft of which one of the trunnions is fixed using a key connection.

Trolley trolley provides:

- fixing the product and its components on the rotary traverse;

- assembly of the product, including wiring;

- canting, i.e. 360 ° rotation of the beam with the product using a worm gear (drive) to ensure assembly;

- adjustment (adjustment) of the product;

- transportation of the product from the assembly site to the places of adjustment, testing and packaging.

However, products can have various configurations and sizes, with many products having a flange with mounting holes located in the center of the structure, i.e. the components protrude up and down from the flange, and the use for different products of the original trolley or removable traverse is not economically feasible.

Therefore, the best option for solving the indicated problem is to use a traverse with a central hole, designed for the maximum size of the product and to install movable plates with grooves on the plane, providing the necessary distance between them to fit the size of a particular product. In addition, it is advisable to arrange the mounting holes for the plates on the traverse in pairs, i.e. to fix said plates on two fixing points, for reliability of fixing of products.

The technical result in the implementation of the utility model is to ensure the assembly, tipping (rotation) and transportation of similar products with different sizes.
