Abstract

The invention relates to the production of reinforced concrete products in a conveyor production. The aim of the invention is to increase the operational reliability of the conveyor. The conveyor contains interconnected cargo carriages 2 on rail tracks 1, a drive for their movement, lifting beams 4 with rollers 5, installed along the rail tracks to rails with wedge sections. The trolley 2 with a backward stop is provided with deflecting stops 12, which are in contact with the hooks of the lifting beams 4 to 6 sludge. from 8

The invention relates to the production of reinforced concrete products in a conveyor production and is an improvement of the invention according to the author. St. No. 1395504.

The purpose of the invention is to increase the operational reliability of the conveyor.

A-A in FIG. figure 4 - node I in figure 2; Fig. 5 is a section B-B in Fig.} in Fig. 6 is a diagram of the interaction of the articulated supports with the hooks of the lifting beams.

The conveyor contains rail tracks I, cargo carts 2 installed at technological posts and interconnected, a drive 3 moving cargo carts 2, lifting beams 4 with rollers 5, wedge guides 6 with wedge sections and a protrusion, stops 7 on cargo carts for moving lifting beams in the course of transferring products and stops 8 on cargo trolleys for reverse movement of lifting beams, as well as interacting with them hooks 9 and 10, located on lifting beams On the cargo trolley in front of the stop 8 for reverse scheni lifting beams for manufacturing transfer direction sharyirno mounted on the axis 31 is deflected propelling stops 12 and stops its rotation 13.

The conveyor works as follows,

After performing the technological operations at the posts of the conveyor, the drive 3 of the movement of the cargo carts 2 is switched on. The carts 2 with the products start moving in the direction of the next post. At the same time, the deflecting stops 12 freely pass over the hooks 10, since they are located above them with a height clearance. After moving the carts to the distance L along the track 1, the stops 7 of the trucks 2 come into contact with the hooks 9 of the lifting beams 4. The lifting beams 4, moving together with the cargo carriages, rolls 5 into the wedge sections on the rails and lifting by wedging sections, the distance La passes, choosing the gap between the lifting beams and the products, raising the products

Oversignment cargo carts 2. During the movement of the carriages, the cooperating stops 8 and the hooks 10 are located at a distance of L. At the end of the course of the cargo carriages, the drive 3 of their movements is reversed, and the carts without products return to their original position. When in motion carts movement

JQ deviating stops 12 touch the hook 10 of the lifting beams, which are in raised condition, are rejected

upward, they pass over the stops 10 to descend to their original position. After that, a distance L ,,, the stops 8 of the cargo carts 2 are engaged with the hooks of the 10 lifting beams 4 and set them in motion. The lifting beams 4 roll down downward along the inclined section of the guides, the hooks 10 are detached from the stops 8 and engage with the stops 12 of the carriage. In this case, the lifting beams 4 cannot move rapidly along the inclined section of the guides 6, but move with the speed of the carriage 2. At the end of the stroke, the hooks 10 descend together with the lifting beams 4 along the inclined section of the guides by an amount equal to the height of the inclined section, get out of the engagement with the deviating stops 12, and the lifting beams 4, having no greater speed, pass the rest of the way and stop, having reached the protrusion of the guides, lowering the products on the carts.

The use of the invention makes it possible to eliminate the shock load on the products when lowering the products from the lifting beams onto the load carriages, to prevent displacement of the products, which increases the operational reliability of the conveyor.
