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 improve operational characteristics, by ensuring the fixation of positions when turning at any angle with any step, as well as the possibility of height adjustment with fixing of intermediate positions.

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;

- the inability to adjust the position of the traverse in height with the fixation of intermediate positions.

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].

Trolley - prototype contains, supported by 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 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 s rack in one of the holes on the disc when you turn the traverse.

Cart - prototype works 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.

Trolley - prototype allows you to fasten, assemble, turn over (turn) and transport products, but it has disadvantages:

- the impossibility of precise adjustment of the positions when turning the traverse due to a certain rotation step, depending on the diameter of the retainer disk and the number of holes in it;

- the inability to adjust the position of the traverse in height with fixing the intermediate positions of the racks.

The purpose of the utility model is to improve operational characteristics, by ensuring the fixation of positions when turning at any angle with any step, as well as the possibility of height adjustment with fixing of intermediate positions.

This goal is achieved by the fact that in the trolley-tilter, containing, supported by wheels, longitudinal beams connected by a cross-beam, mounted on the longitudinal beams of the rack, mounted on the last rotary beam and mounted on the axis of its rotation position lock, the latter is made in the form of a friction disk, installed in a split plate with a clamp, and the racks are made telescopic with the possibility of changing the height and fixing the intermediate positions.

The technical result in the implementation of the utility model is to improve performance by providing accurate adjustment of the position of the beam when it is rotated to any angle with any step that does not depend on the diameter of the lock disk and the number of holes in it (friction locking), as well as increasing the usability of the introduction height adjustment of the traverse with fixation of intermediate positions (telescopic racks).

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).

Products are metal structures of complex configuration, in which it is necessary to carry out complex and saturated electrical installation in different planes and at different angles, while the mass of the products is relatively small 5-10 kg.

The tilting cart is a welded frame, in the form of an I-beam, 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.

Trolley trolley provides:

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

- assembly of the product, including wiring;

- canting, i.e. 360 ° turn of the beam with the product, manually to ensure assembly, with fixation of positions;

- adjustment (adjustment) of the product;

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

However, with saturated wiring and a complex configuration of the basic design, the pitch of the rotation angle should be minimal and not depend on the diameter of the retainer disk and the number of holes in it, as in the prototype. Increasing the diameter of the disk to increase the number of holes in it (minimizing the pitch) is impractical. In addition, for the convenience of work, it is necessary to adjust the position of the traverse (platform) in height with the fixation of intermediate positions in the range of 500-800 mm.

Therefore, the best option for solving the indicated problem is to use a position lock when turning the traverse in the form of a friction disk mounted in a split plate with a clamp (screw with a handle), as well as telescopic racks with the possibility of adjusting their height with fixing intermediate positions with clamps similar to that mentioned.

The purpose of the utility model is to improve operational characteristics, by ensuring the fixation of positions when turning at any angle with any step, as well as the possibility of height adjustment with fixing of intermediate positions.

The technical result in the implementation of the utility model is to improve performance by providing accurate adjustment of the position of the beam when it is rotated to any angle with any step that does not depend on the diameter of the lock disk and the number of holes in it (friction locking), as well as increasing the usability of the introduction height adjustment of the traverse with fixation of intermediate positions (telescopic racks).
