Description

The invention relates to industrial transport and can be used to transport goods in cramped conditions with the need to automatically change the distance of cargo transportation and the length of the conveyor belt, for example, when refractory bricks are fed into a cement kiln for producing lining operations.

Known sectional conveyor containing mounted on the frame conveyor sections and the mechanism for their issuance and acceptance 1.

However, the length of this conveyor is limited, since only two sections can be installed on the frame, extending in opposite directions of the frame.

Closest to the invention is a sectional conveyor comprising a frame with mounted conveyor sections, a lifting and lowering mechanism, and a mechanism for issuing and receiving sections having a carriage with an anvil 2 mounted on it.

In this conveyor, a bundle of conveyor sections is mounted on the folding shelves of a lifting and lowering mechanism, the carriages of which are fixed in the upper position by a braking device. When it fails, it is possible that the sections pack will fall down or skew, which creates an emergency. In addition, to ensure the necessary sequence of disassembly operations or a set of packs of sections, the cassette is equipped with synchronization mechanisms having a complex structure. The carriages of the mechanism for issuing and receiving sections have stops that interact with the copiers in the extreme positions to turn them from one fixed position to another. This requires a greater stroke of the carriage than the length of the conveyor section, which is another disadvantage of the known construction.

The aim of the invention is to increase the safety of the operation of the conveyor and reduce the time for shifting sections with an emphasis.

This goal is achieved by the fact that in a sectional conveyor, including a frame with installed conveyor sections, a lifting and lowering mechanism and a mechanism for issuing and receiving sections, having a carriage mounted on it with an emphasis, the frame is equipped with pivotally supported spring-loaded shelves and dogs with the possibility of their interaction with the location of the spring-loaded support shelves in the extreme upper position, with the emphasis installed on the carriage by means of a turntable.

FIG. 1 shows a sectional conveyor, general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 — node I in FIG. one.

A section conveyor consists of conveyor sections 1, a frame 2 on which a mechanism for issuing and receiving sections is mounted, and racks 3 (FIG. 2) equipped with a lifting mechanism.

The mechanism for issuing and receiving sections is made in the form of a driving carriage 4 (FIG. 4), on which a turntable 5 is mounted, equipped with a pivotally mounted stop 6 with a one-sided clamping spring 7 to the turntable.

The lifting and lowering mechanism is made in the form of vertical lift carriages 8 with drives 9 (Fig. 2). On the carriages of the vertical lift 8, hinged shelves 10 (Fig. 3) are mounted on the axis 8, 5 having a finger 11. On the uprights 3, pivotally supported spring-loaded shelves 12 with a tooth and a spring 13 and pawls 14 are mounted on the axis (Fig. 2).

Conveyor section 1 is made in the form of f. belt conveyor on track rollers with electro-mechanically driven drum.

The operation of the conveyor is carried out in the following order.

On pivot bearing shelves 12 lift

5, a bundle of sections 1 is installed by means of a crane, for example a crane. Vertical lift carriages 8 rise to the upper position and take 10 packs of sections on the folding shelves, while, turning the 11 folding shelves with their fingers, the last flange 12 are fixed in the extreme upper position a tooth with paws 14. When lowering the carriages 8, the second from the bottom of the pack section presses the pawl 14, releasing the supporting shelves 12, which then return the spring 13 to a horizontal position and go under the frame of the second from the bottom section. Next, the second bottom and the upper sections of the packs lying on it are hung on shelves 12, and the lower section 5} is placed on frame 2. The carriage

, 4 of the mechanism for issuing and receiving sections, interacting with the support 6 with the frame of the conveyor section, outputs it from frame 2, and then returns to its original position. At the same time, the separation from the pack and the descent of the following sections occurs in a similar way, and then it is issued.

As the length of the conveyor belt decreases, the turntable 5 is turned by the operator 180 ° about the vertical axis, and then the carriage 4 makes a turn towards the track sections. Passage under the frame

0 the near section, the stop b is rotated and then returned by the spring 7 in ver. ticking position During the reverse course of the carriage 4, the path of the conveyor moves inside the frame 2. With the full entrance into the frame, section 1 is disconnected from the path.

5 During upward movement of the vertical lift carriage 8, the folding shelves 10 lift section 1. At the same time, the section fits under the pack, lifts it, and passes the shelf 12, turning it upwards, which then returns to its original position with spring 13. In this case, the pawl 14 must be previously removed by the operator from engagement with the shelf 12. When the vertical lift 8 carriages run down, the bundle is placed on the flanges 12 and the carriages are moved to the lower position. Further, the reception of sections and a set of packs occurs in a similar order.

The accumulated stack of sections is taken out of frame 2 by a lifting mechanism and is ready for transportation to other working fronts.

This embodiment of the conveyor increases the safety of his work and reduces the time for shifting sections focus.
