Description

(54) ASSEMBLY OF INTERMEDIATE-POTENTIAL PRODUCTION OF CONSTRUCTION PRODUCTS

one

This invention relates to the manufacture of precast concrete and reinforced concrete products.

A known installation for the manufacture of reinforced concrete products, containing installed in two rus conveyors of molding and heat treatment of products, connected by transfer carriages and descender-lift to the lifting-lowering frame through which the paths of the transfer carriages 1 pass.

The closest technical solution known is a unit for the interim production of building products, which is mounted on a base for transferring molds, along which equipment for stripping, cleaning, lubricating and assembling forms, installing reinforcement, laying and compacting concrete mixtures are located in the technological sequence , post-heat treatment, placed parallel to the conveyor, and the ends of the latter are connected to each other by transfer carts 2.

The disadvantage of this device is low productivity and high power consumption.

This goal is achieved by the fact that the unit is a continuous-flow production of building products, containing a base-mounted conveyor for moving molds, along which equipment for stripping, cleaning, lubricating and assembling forms, installing reinforcements, laying and compacting concrete in them is located in the technological sequence mixtures, heat and moisture treatment post, placed

Q parallel to the conveyor, and the ends of the conveyor and the post are connected to each other by transfer carriages, equipped with a railing installed above the post of the heat-humidity treatment with a railing supported on them

15 by a manipulator, the post of heat and moisture treatment is made in the form of several successively installed multi-chambers with packers, and the ends of the rails of the overpass are placed above the transfer carriages.

FIG. 1 shows the unit intermittent production of products, top view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. 2

The unit consists of a conveyor 1, in the form of, for example, a non-driving roller table 2, on which rollers 3 forms 4 are installed, a mechanism 5 for stepping movement of forms 4 with a pusher 6 and a gripper 7, vibrating plate 8 with lowering sections of the roller table 9, overpass 10 and a concrete paver 11 .

Parallel to the conveyor 1, there is a post of heat and humidity treatment of the steam steaming chambers 12 with lids 13 and palletizers 14. On the upper longitudinal walls of the chambers 12 there is a ramp on which the rail tracks 15 are located, the ends of which extend beyond the chambers 12 and rest on ramps 16 and 17 On rail tracks 15, a movable portal 18 is installed with a drive of longitudinal movement 19 and a manipulator consisting of a winch 20, a cable-block system 21 connected to a cross member 22 having grippers 23 for engaging (gripping) with forms 4 .

Rails 24 and 25 are installed at the ends of the conveyor 1 and the post of the heat-moisture treatment of products, which run under the ramps. On tracks 24 and 25, respectively, transfer carriages 26 and 27 are installed, each of which has a longitudinal movement drive and a roller table 28 with rollers 29.

The height of the traverse 22 of the manipulator of the movable portal 18 is selected according to the conditions of its interaction with the lids of the 13 meter chambers 12 and the forms 4 with the products when installed on the transfer carts 26 and 27, as well as on the lower supports of the packers 14.

The unit of discontinuous production of building products works as follows.

In the initial steady state mode, the transfer carts 26, 27 are located on the axis of the conveyor 1. On the carriage 27, there is a form 4 with the finished product. The descending sections of the roller table 9 vibroplatform 8 are raised with a form 4 with a freshly molded product. The lids of 13 two multi-chamber chambers are 12 sleepers and lie on the lids of the neighboring chambers 12. Portal 18 is located on the overpass 16.

The drive of the mechanism 5 for stepping the molds 4 is turned on and the pusher 6 is gripping the mold from the carriage 27, pushing through all the molds on the conveyor table 2 of the conveyor 1. On the carriage 26 (on the rollers 29 of the roller table 28), the mold 4 with the freshly formed product rolls and the pushing cycle ends .

The drive of the transfer carriages 26, 27, which move along rail tracks 24 and 25 under ramps 16 and 17, is switched on, while the trolley 26 carries the form 4 with a freshly molded article. The transfer trolleys 26 and 27 stop along the axle rail of the 15-meter chambers 12.

The winch 20 of the mobile gantry 18 is turned on, the traverse 22 is lowered, and the gripper 23 grasps the form 4 and lifts it. The drive 19 for moving the movable port 18 is turned on and it rolls over to the chamber 12, stops above the opening and sets the form 4 with the product onto the brackets of the shipper 14. The traverse 22 of the manipulator is lifted to the upper position, and the portal 18 is rolled to the next chamber 12, the traverse 22 of the manipulator capture and raise the form 4 with a heat-treating device with the secret product and the portal 15 is moved to the ramp 27, stop and lower the form 4 with the heat-treated product onto the rollers 29 of the roller table 28 with the transfer carriage 27.

The transfer carts 26 and 27 roll and stop along the axis of the conveyor 1. Subsequently, the loading and unloading cycle of the forms 4 from the chambers 12 is repeated until one of the chambers 12 is fully loaded with the forms 4 with freshly molded products Do not unload.

By the manipulator of the movable portal 18, the lid 13 seizes, transports and closes the chamber 12 with the molded products for heat treatment. Likewise, the movable portal manipulator is opened with an 18-meter chamber 12 with a heat-treated product and the cycle is repeated.

The use of building products in industry will increase productivity and reduce their energy intensity

 manufacturing.
