Abstract

Usage: the invention relates to means for transporting long loads. SUMMARY OF THE INVENTION: A stepping conveyor comprises a fixed frame; the load-bearing beams of which consist of horizontal sections for step-by-step transportation; products by rolling, sections with supports fixed to them in the form of lodgements for step-by-step movement of products by transferring, sections in which one of the bearing beams of the fixed frame is made with cutouts, and sections with parallel cutouts for removing products from the conveyor or feeding them to the conveyor during transportation in the transverse direction. Each support for the pipes of the movable and fixed frames is made in the form of two lodges located opposite each other on different sides from the longitudinal axis of the conveyor. The supporting surfaces for the pipes of each pair of lodges of the movable and fixed frames are located at different levels. The difference in the levels of the supporting surfaces for the pipes of each pair of lodges of the fixed frame is equal to the difference in the levels of the supporting surfaces for the pipes of each pair of lodgements of the fixed frame. The lodges of the movable and fixed frames with large levels of pipe support surfaces are located on one side of the longitudinal axis of the conveyor, and the lodges with lower levels are located on the other side of the longitudinal axis of the conveyor. 6 ill.

moving products by rolling, sections with supports fixed to them in the form of lodgements 3 for step-by-step moving products by shifting, sections on which one of the supporting beams of the fixed frame is made with cutouts 4 (Fig. 4) and sections with parallel cutouts 5 (Fig. 1) for removing products from the conveyor or feeding them to the conveyor during transportation in the transverse direction.

The conveyor also contains a movable frame b mounted with the possibility of reciprocating in the longitudinal and vertical directions with a pipe lodgement and pushing elements made in the form of brackets 8 with rotating rollers 9 mounted on them (Figs. 1 and 4).

The conveyor also includes a lifting device 10, consisting of two power cylinders 11, two parallel systems of thrust 12 and levers 13, interconnected by shafts 14, in order to synchronize the rotation of the parallel levers, bearings 15 mounted on a fixed frame and designed to support levers 13, double-flange support rotary rollers 16 at the upper ends of levers 13 supporting and guiding the movable frame 6.

The conveyor also includes a drive of longitudinal movement 17, consisting of a power cylinder 18 pivotally connected to the fixed 1 and movable 6 frames.

The positions of the pipes on the step conveyor during transportation are indicated by the technological positions (pos. 1-pos. 7).

The number of identical items is determined by the number of process steps.

At position 3 (Figs. 1 and 5), each support for the pipes of the movable and fixed frames 7 and 3 is made in the form of two lodgements, located opposite each other on opposite sides from the opposite axis of the conveyor, while the supporting surfaces for pipes of each pair of lodgements are movable and the fixed frames are located at different levels (marks a and b, c and d), while the difference in the levels of the supporting surfaces for the pipes of each pair of lodges of the fixed frame e is equal to the difference in the levels of the supporting surfaces for the pipes of each pair of lodgment of the moving pair f, while Options movable and fixed frames with high levels of support surfaces for the tubes (b and d) are located on one side of the longitudinal axis of the conveyor, and lodgements with lower levels of (a and c) - on the other side of the longitudinal axis of the conveyor.

In the areas indicated by pos. 2 (FIG. 1), prisms 19 (FIG. 6) are provided for

fixing the position of the pipes transported by rolling.

The step conveyor works as follows:

The lifting device 10 and

the power cylinders 11 through the traction system 12, levers 13 with support rollers 16 raise the movable frame 6 to the upper position, while the lodgement of the movable frame removes the product from the loading device 5 (pos. 1) and lifts it above the fixed frame 1 and lodges 3. Then the drive cylinder 13 of the longitudinal movement drive 17 moves the frame 2 with the product one step in the direction of movement of the products. The lifting device 10 is turned on and the movable frame 6 is lowered, and the product is laid on the fixed frame 1, after which the drive 17 returns the movable frame 6 to its original position, and the conveyor

5 Ends the cycle of work.

The sequential activation of the hoist and hoist drives is automatic. Then the cycle repeats and the walking conveyor is full

0 transported long products of circular cross section, e.g. pipes. At the same time, the products located at positions 2, 4 and 6 are transported by rolling in horizontal sections 2 of the non-movable frame 1 under the pressure of the pushers 8 with the pressure rollers 9 of the movable frame when it is moved horizontally in the upper position, and at 1.3, 5 and 7 products are transported

0 shifting.

At the 3rd position, the products are moved in an inclined position (see, Fig. 5), which ensures reliable operation of the conveyor when the defective hydraulic wash

5 inner cover. In the remaining positions, the articles move horizontally.

At the 5th position, products are removed from the stream, for example by roller

0 conveyor.

At the 7th position, the step conveyor is unloaded.

Thus, in comparison with the prototype, the proposed step conveyor

5 provides increased reliability of the conveyor during hydraulic washing off of the defective inner coating.

When transporting products in one technological cycle, the conveyor provides simultaneously with shifting to

horizontal position of long round products, shifting to an inclined position to provide reliable gidosymyva, rolling to horizontal

and inclined positions, as well as

Allowed to arrange the removal of products from the potatoque in the transverse direction to any

technological position.
