Description

The group of inventions relates to freight vehicles and can be used to obtain a pulsed directional impact on the vehicle and its stepwise movement in a given direction, in particular, a walking vibrating press for the manufacture of building blocks.

A known method of horizontal stepwise movement of heavy loads, described in a device for repair and construction of a railway track, which provides lifting and moving cargo using articulated frames fixed with offset on the casing with hydraulic drive. The load is displaced by retracting the hydraulic cylinder rod.

A known method of implementing directional movement of self-propelled systems based on the transmission of rotation from the engine to an inertial-pulse mechanism containing two parallel shafts with imbalances made to rotate in opposite directions in the plane of rotation of the unbalances perpendicular to the direction of movement of the system, while in the plane of direction of movement the systems provide the ability to swing the frame bearing an inertial-pulse mechanism (AS USSR No. 151574, class B63C 29/06, 1962).

This method provides a strictly directed movement without separation of the supporting surface from the ground.

A known method of converting directed mechanical vibrations into unidirectional intermittent translational motion for controlled movement of a vehicle in a given direction, based on the interaction between two masses of the system, one of which is inertial. An unbalanced system with a center of mass that coincides in a static state with the center of gravity of the same system is used. The movement of the system is carried out by sequential step movements at the moments of the pulsed action of inertial forces along the long axis of the device directed towards the movement. This method of controlled movement of the vehicle in a given direction involves the use of a propulsion device to obtain traction, which generates pulses of inertial forces (RF Patent for the invention No. 2280513, CL 1/06, published on July 27, 2006).

The disadvantage of this method is the difficulty of using an unbalanced rolling system of a rotating element of an elliptical treadmill to obtain directional mechanical vibrations.

All-terrain vehicles are known from the prior art, the method of movement of which is based on the displacement of the center of gravity of the vehicle, forcing it to move in the direction of displacement of the center of gravity (AS USSR 380517 A from 05.15.1973; US patent 2977714 A from 04.04.1961; patent RF invention No. 2196260 dated 01/10/2003).

The disadvantage of these methods is the spherical or cylindrical design of their devices that implement these methods and the inability to provide stepwise movement of heavy loads.

A known machine for the manufacture of wall stones (vibropress), consisting of a matrix having sides and hollow formers, and an electric vibrator and containing a shock absorber that dampens excessive vibration and provides alignment - a uniform distribution of the weight of all structural elements of the machine along the center of gravity, which, in addition, serves as an additional the support of the machine and prevents it from slipping during vibration (RF patent for utility model No. 75983).

The disadvantage of this machine is the stationary position and the inability to conveniently and quickly unload finished construction products.

Known vibropresses for the manufacture of wall (building) blocks of the Italian company Kadona brand 842 Hydr. Vibrating presses, which are a metal frame structure, on which are installed: a power frame with a matrix and a punch, a front driving wheel electric drive, a hydraulic drive for the matrix and punch, a vibrator, shock absorbers, an unloading mechanism and rear support wheels for moving the vibropress after unloading the finished unit to the floor.

The disadvantage of this device is the loss of productivity due to the irrational movement of the vibrating press when unloading the finished product.

Analysis of patent and other scientific and technical information from the prior art showed that power drives are widely used for unloading finished building products from vibrating presses, for example, for pushing out finished blocks, for pushing blocks onto rotary tables and roller tables, and also for unloading on the floor and on pallets. But the mechanisms of step movement in any direction - walking machines and vibrating presses to ensure continuous unloading of building blocks in the information sources have not been identified.

The technical task of the claimed group of inventions is to increase the efficiency of a freight vehicle with successive step movements in any direction, achieved by using the inertial force of the freight vehicle itself, acting in the direction of its movement as a result of the pulsed action of the power drive kinematically connected with the freight vehicle. The technical result of the invention by the method is achieved by the fact that in the method of converting the directed pulsed action of inertial forces to the sequential stepwise movement of a cargo vehicle in a given direction, based on the use of a propulsion device to obtain an impulse of inertial forces and converting the directed mechanical action into a directional intermittent translational motion, as propulsors use a power drive-step, kinematically connected with a cargo vehicle ohm, which rests on the floor surface and provides an impulse of inertial force of the cargo vehicle when pushing it to provide a shift in the center of gravity of the cargo vehicle, forcing it to move ("fall") in the direction of the center of gravity to the stop, at a distance of a given step and in a given direction.

The implementation of the proposed method can be carried out on any cargo vehicle (figure 1), where it is necessary to move it stepwise in different directions and with a given step length. In the claimed particular case, the method of converting the directed pulsed action of inertial forces into the sequential stepwise movement of a freight vehicle is carried out in a vibrating press for the manufacture of building blocks.

An object of the invention is to develop and equip the vibrating press with a moving mechanism for laying finished products on the concrete floor of the workshop or on pre-laid pallets along the trajectory of the step-by-step movement of the vibrating press in any convenient place.

A positive result of the invention is expressed in increasing the operating efficiency of the vibrating press due to the additional useful properties of the walking mechanism (drive-step), which provides the finishing operation - economical, reliable and quick unloading of finished products.

The solution of the technical problem and the positive result of the invention is achieved by the fact that the device, which is a vibrating press for the manufacture of building blocks with a mechanism for moving and unloading finished products, contains a power frame, on the traverse of which a drive for raising and lowering the matrix and raising and lowering the punch, vibrators and shock absorbers are fixed , and the wheels that make up the movement mechanism, unlike the prototype, has a pushing mechanism on the vibrating press frame in the form of a power drive-step, for example, a hydrocycle a nut that is pivotally mounted on the power frame and abuts against the floor surface, while the step-drive provides a pulsed effect on the power frame and inertial transfer (shift) of the center of gravity of the vibrating press, which causes it to “fall” in the direction of the center of gravity shift, transmitting inertial motion the front support wheels of the vibrating press, while moving it forward by the distance of the step specified by the step-drive.

An essential distinguishing feature of the invention is the presence of a repulsive mechanism in the form of a power drive-step, in the claimed particular case - a hydraulic cylinder that provides a given step-by-step movement of the vibrating press.

The invention is illustrated by drawings. Figure 1 shows a schematic illustration of a method of converting a directed pulsed action of inertial forces into a sequential stepwise movement of a cargo vehicle in a given direction; figure 2 shows the device is a vibrating press with a step-drive; figure 3 a, b, c, d, d - the same, the working cycle of the vibrating press from the beginning of the pressing of building blocks and to the unloading of finished products.

Description of the device.

A vibrating press with a walking mechanism for the manufacture of building blocks (Fig. 2) includes a power frame 1, on the traverse of which a drive 2 for raising and lowering the matrix 3 and raising and lowering the punch 4, a matrix 3 and vibrators 5, mounted on 4 shock absorbers 6 to to the cheeks of the guides 7. The movement mechanism - the power drive-step is a pusher on the frame 1 of the vibrating press in the form of a power cylinder 8, the rod of which abuts through the stop-shoe 9 to the floor surface. In the upper part, the cylinder 8 of the power drive is fixed in a pivotally swivel mounting unit 10. During operation, the walking mechanism - the power drive-step (Fig. 1, Fig. 3) provides an insignificant shift of the center of gravity of the vibrating press forward, in the direction of displacement of the center of gravity, which causes its "fall" under its own weight forward and at this moment due to the front support wheels 11 of the vibrating press it is moved forward by a distance of a given step.

The power drive-step is designed to ensure the forward movement of the vibropress. The vibropress moves to a distance of a given step and a little more by inertia, taking into account the resistance of the rolling force over the surface. In practice, this can be neglected, and experimentally adjust the required step distance. Experimental studies have confirmed the effective operation of the vibrating press. To move a vibrating press weighing 0.5 tons over a distance of 0.5 meters in five seconds, a power of 3 thousand Newton (about one horsepower) is enough. In addition, this principle and the claimed mechanism has a much greater applied effective power, no slippage, less loss of power consumption, and also produces a step at the required distance.

The power drive can be any, but in this particular case it is hydraulic, pneumatic cylinders or actuators. Their cost is two to three times lower than the usual wheel-motor mechanism of movement, and in terms of reliability and motor resource exceeds the existing several times.

Vibrating press works by means of a walking mechanism, moving around the production site on the front support wheels, leaving unloaded construction products. During the operation of the vibropress, the molded blocks are laid out with an adjustable interval directly onto the concrete floor. The full cycle of product formation lasts 30-40 seconds.

Loading the finished mixture into a vibrating press is carried out using a special loading trolley and a lifting mechanism.

In the absence of free production space, a walking vibrating press can be used in a limited area with the formation of finished products on pre-laid pallets along the path of movement of the vibrating press.

Drives are controlled from the control panel or semi-automatically without operator intervention in the production cycle of mechanisms in production.
