SU589168A1 - Load trolley of overhead push-type conveyer - Google Patents

Description

FIELD OF THE INVENTION The invention relates to a lifting and transport machinery industry and concerns the design of cargo carriages of an overhead push conveyor.

Known cargo carriage overhead pushing conveyor, including the head and pushing carriage mounted on their corners leading stops and rollers, which are placed on the cargo track, having in the place of transfer. Trucks cutouts in the upper shelf 1.

However, such a structure does not prevent the trolley from running out of the pusher body when it is pushed from one conveyor to another.

Also known cargo truck suspension pusher conveyor, including the head and pushing carriage mounted on their buildings leading stops and rollers, which are placed on the cargo track, having in the place of transfer carts cutouts in the upper shelf 2.

However, such a structure also does not prevent the trolley from running out when the conveyor is operating at high speeds during the pushing process.

The purpose of the invention is to prevent the trolley from running out of the traction body when it is pushed from one conveyor to another in conditions of high speed of the engine.

This goal is achieved by the fact that the leading support of the pushing carriage is provided with a shoulder with a holding stop and is made with the possibility of moving in the guide body of the pushing carriage by means of a counterweight mounted on the roller axis and placed inside the cargo track, and by means of on the leading emphasis of the protrusions interacting with the upper shelf of the cargo track.

FIG. 1 shows the proposed trolley, a general view; in fig. Figure 2 shows a push-in carriage with a controlled stop in the working position; in fig. 3 - the same, in the initial position; in fig. 4 shows a front view of a pushing carriage.

A freight trolley transported by a conveyor body along a freight track 1 consists of a head carriage 2 connected by a cross member

3 with a pushing carriage 4, which includes a housing 5, running rollers 6, guide rollers 7. The leading stop 8 of the pushing carriage is provided with a shoulder 9 with a holding stop 10 mounted on an axis 11 and having a counterweight 12. The stop 8 is adapted to

movement in the guide housing 5 at

using the counterweight lever 13 mounted on the wasp of the rollers 6 and placed inside the cargo track 1, and by means of the projections 14 installed on it, interacting with the upper shelf of the cargo route 1. The protrusions 14 are made to widen the distance between the upper channels of the channels forming the path, and keep the stop 8 in the off position (under the upper shelves of the cargo route). The holding stop 10 can be tilted only in the direction of movement of the pusher 15 attached to the chain 16.

There are notches 17, 18 and inclined tires 19 in the transmission zone in the upper part of the cargo track.

The load carriage moves along the load path when the pusher interacts with the leading support of the head carriage. At the same time, the stop 8 of the pushing carriage 4 is constantly in the set position, due to the enhanced protrusions 14, which slide along the inner surface of the upper shelves of the track, without giving the stop a lift. When the carriage (coupler) enters the transfer zone from the conveyor to the conveyor, the chain pusher disengages from the upright of the head carriage and the cart stops. At this moment, the stop 8 of the pushing carriage, under the action of the counterweight 13, rises upward, appears in the notches 18 of the track shelf and occupies the working position. Behind the free chain pusher, approaching the pushing stop 8, tilts the holding protrusion 10 forward, which passes the pusher and, under the action of the counterweight 12, takes up the working position. The pusher 15 interacts with the leading stop 8 and pushes the load trolley into the zone of action of the receiving body of the receiving conveyor (gear. The protrusion 10 interferes with the free

run trolleys forward. The insertion of the pushing stop 8 takes place when the carriage protrusions 14 onto the inclined plate 19 when the carriage is pulled. As a result, the stop 8 disassociates from the J pusher of the transfer conveyor chain.

Thus, the installation of an adjustable stop having two projections, one of which is movable, in the pushing carriage of the trolley makes it possible to increase the reliability of the conveyor and improve its performance.
