Vibrocomplex universal mobile

The invention relates to the production of concrete and reinforced concrete products for road construction in the factory and at landfills.

Currently, there is a wide variety of different installations for the production of concrete and reinforced concrete products, the closest of which to the proposed invention is the installation according to patent No. 2080988 of 10/06/1997 containing a frame with sides, elastically supported on the base, insert.

A disadvantage of the known device is the impossibility of its use as a universal installation for the manufacture of a wide range of products, because the vibrator used is designed to interact with the load.

technical result, the invention is aimed at achieving KOTOpoio is to create a universal vibro-complex for the production of a wide variety of products with high performance.

The specified technical result is achieved in that the installation containing the frame with the sides, elastically supported on the base, the insert, is equipped with at least one additional insert and at least one vibrator mounted on the frame, made with at least one flip board, while Vibrator mounts may be located below the frame.

To increase the efficiency of at least one liner is configured to install vibropruss.

The basis for reducing the pressure on the soil can be made in the form of a welded frame.

The invention is illustrated in the drawing.

Vibrocomplex universal mobile "GEVIT-1 consists of the following structural elements:

support frame 1

vibro-frames (frames with sides) 2

-forming boards 3

forming inserts 4

-System stops and locks 5 for fixing structural elements

shock absorbers 6 between the supporting frame and the vibration frame

-vibrators or vibration units 7

-drive (not specified)

control panel (not shown)

Traverse (not shown).

The supporting frame 1 is the supporting structure of the vibrocomplex; it is a rigid welded structure.

Vibrating frame 2 is a rigid welded frame on which vibration mechanisms 7 are installed (vibrators or vibration blocks). The rigidity of the vibration frame provides an almost equal amplitude of vibrations of the vibration frame and the forming metal insert 4 attached to it. The vibration frame is supported by elastic supports (shock absorbers) 6, which transfer the load to the lower stationary support frame and foundation (or base). The elastic supports are also vibration isolators, since their natural frequency of oscillation is several times less than the vibration frequency of the vibro frame. Due to the effect of vibration isolation, only static load is transmitted mainly to the foundation.

Products for road construction have high demands on the degree of compaction of the concrete mix. At the vibrocomplex, such an arrangement and fastening of vibratory mechanisms is provided, in which the most effective effect of vibration on the concrete mixture is achieved. Depending on the configuration of the molded products, the vibration amplitude can vary from 0.1 to 1 mm by adjusting the vibrators. Depending on the length of the vibro-complex, it is equipped with vibration mechanisms from one to four.

On-board equipment is the enclosing and forming structure of the vibrocomplex, and serves to perceive the lateral AaBJieiiHH concrete mixture. The inner surface of the sides 3, which is the working surface, provides the configuration of the molded products. The working surface of the sides 3 has a higher purity of processing in order to ensure the quality of the front surface of manufactured products. On the outer plane

ribs are located on the sides, which prevent deformation of the sides, curvature of the plane.

The forming sides are fixed with locks 5. The sides can be removed if necessary. In the process of work, only the opening-closing of the sides is carried out, which ensures minimal laboriousness during the operation of the vibrocomplex. Universal onboard equipment reduces metal consumption. forms. Immediate formwork allows you to increase the turnover of the tooling.

Shaping metal liners 4 are a bending-welded structure with stiffeners, holes for stops and mounting holes. The design of the forming inserts provides when installed on

vibrocomplex the gap between the connecting elements within 2 mm. The increase in the gap will entail the loss of the binder during the molding of products and its hit on the lower vibration mechanisms.

Locks and stops are designed to fix all structural elements of the vibrocomplex. The design of the locks ensures their quick opening and closing. These are screw, wedge, lever, eccentric, bayonet locks.

The vibrocomplex can be equipped with vibration mechanisms with a voltage of 42 or 380 V.

Vibrocomplex universal mobile due to its relatively small mass (within 2.5 tons with molded products) does not require special foundations for installation. A fairly flat dense base.

The vibrocomplex works as follows:

A reinforcing cage with mounting loops fixed to it is installed in metal inserts, previously cleaned of residual concrete mixture and lubricated. Then, with the help of a lifting device and a traverse, the prepared metal insert is installed on the vibrocomplex and fixed on it.

The concrete mix prepared for molding with strictly regulated indicators for workability from the feed hopper is poured into the molding space of the installation. Filling the vibrocomplex with concrete mixture is carried out while the vibrating / building systems are in operation.

During the vibroforming process, the concrete mixture is evenly distributed along the length of the insert. The vibration molding process is controlled from the control panel.

At the end of the vibroforming process, the forming sides of the vibrocomplex are opened using a lifting device and the traverses remove the metal insert with the molded product from the vibrocomplex and transport it to the site of the set with strength products.

 molding cycle is repeated.

If necessary, after loading the concrete mixture, with the ongoing process of vibration, a vibrated load with an additional vibrator is installed on top of the laid concrete mixture from above, and after installation, the vibro-load vibrator is turned on;

- the vibration process “bottom and top”, due to the synchronization of the vibrators, provides the required concrete compaction;

- after a period of time specified by the technology, the vibration process stops (the vibrators of the vibrating table and vibroprigruz turn off);

The vibro-load is removed, then the sides of the vibro-complex are opened and, together with the liner, the product is removed and sent to the post of curing (heat treatment or natural exposure);

- further, the new insert is installed on the vibration table of the vibrocomplex, with the help of locks and stops its sides are fixed and the process is repeated again.

The proposed installation allows using the principles of vibropressing to obtain products:

- up to 3000 mm long and even up to 5000 mm wide, up to 1000 mm wide, up to 1000 mm high with a tray profile depth of up to 600 mm, i.e. all types of trays for road construction;

reduce the formation cycle to 20 minutes per cycle or 20-25 moldings per shift (8 hours) (compare with one cycle per day during injection molding) due to almost “immediate stripping (removal) of the product from the molding unit, which ensures its high performance; Due to the required set of inserts in one installation, it is possible to quickly form the entire required range of concrete products for the construction of roads of all categories of complexity.
