Description

I

The invention relates to mechanical engineering, in particular to lifting and transport engineering and can be used for maintenance of products and as a tooling.

A device for maintenance of products is known, which comprises interconnected carts of a frame structure with roller supports 1, which are interconnected by quick-release connections.

The disadvantages of this device are its narrow purpose, the impossibility of installing products of various geometric shapes and diametrosis.

The purpose of the invention is to increase productivity.

The goal is achieved by the fact that each trolley is equipped with coupling for the product and parallel guides, one of which is made in the form of screws connected to the left and right threads, while

, one of the ends of one of the screws is connected to the rotational drive, and the roller bearings are made with an internal thread and mounted on these guides.

FIG. 1 shows one of the carts of the device, a general view; .on FIG. 2 is a side view device for maintenance of products.

The device contains two mobile carts. The design of each bogie contains two frames 1 with handles 2, four guides 3 along which supporting elements consisting of a slider A move, and roller supports 5 fixed on it.

Claims (1)

The sliders are pairwise connected by a screw mechanical strap 6, made in the form of two screws 7 and 8 with left and right threads and connected by a clutch 9, and the shanks of the screw mechanism are removed from the frames 1, which makes it possible to connect the spry 10 to any of them. Each frame 1 has two rollers 11, a stopper 12 and a bracket 13 with a quick-release pin for fastening the brackets 15. The carriages are interconnected by quick-disconnect couplings, which serve as a limiter for carriages relative to each other and made in the form of a tape measure 16, secured constant on one of the carriages, and a cable 17 which is connected to one end of a tape 16 and a second end fixed to pin 18, facilitating fastening a cable 17 up responses ti x 19 second carriage. The device for the maintenance of the products works as follows. Depending on the length of the product and the regulations of the work carried out, one, two or a few carts can be used. Each trolley is mounted with rollers 11 on special rails mounted on a table, rack, container or vehicle platform. The product with which to operate is hung horizontally by a lifting mechanism and is fed to the roller bearings 5 trolleys that are pre-installed and locked by the stopper 12 at a certain distance from each other. Rotating the screw mechanism with the handle 10, thereby moving the roller supports 5, brings the latter to the bypass of the product, after which the product is detached from the lifting mechanism and appropriate operations can be performed with it. The product is raised or lowered, tilted in the right direction to the required angle within certain limits by rotating the screw mechanism. 6 corresponding pairs of rollers with the help of the handle 10, as a result of which the roller supports 5, moving or moving apart, move the products in the vertical plane to the required position. The rotation of the product around its axis is carried out on roller bearings 5. The product is fastened on carts by means of straps 15 on each carriage. The undocking (joining) of the component parts of the product is carried out by fixing each part on one of the trucks with the aid of studs 15 followed by separation of the trucks, previously uncoupling them with the stopper 12 to the desired distance, and if it is necessary to limit the separation of parts of the product, a sliding limiter with limitation the length of the cable 17 by fastening the finger 18 into the corresponding hole 19. In the undocked state and in the process of docking, all the above mentioned operations can be carried out on the cart with each part of the product. ation as a whole product. The invention makes it possible to increase labor productivity by providing maintenance for products of various geometric shapes and sizes. Claims The device for maintenance of products, containing interconnected quick-disconnect joints of frame frame with roller bearings, characterized in that, in order to increase productivity, each trolley is equipped with straps for the product and parallel guides, one of which is made in the form of coupled screws to the left and right teeth, one of the ends of one of the screws connected to the rotational drive, and the roller bearings are made with internal thread and enes on these guides.
