Description

The invention relates to the production of building materials by vibropressing foundation blocks from semi-dry (hard) concrete.

The installation is a self-propelled equipment, during the operation of which the blocks are molded directly onto a flat concrete working platform, then they are aged on it in order to accumulate strength. The starting material for the preparation of the molding sand are: aggregate, binder and water. The principle of operation of the installation is to obtain simultaneously two molded blocks or one specified strength by vibrocompression from semi-dry (hard) concrete mixtures directly on the working platform.

The mobile, mobile vibrating presses developed by the NEMP company (http://nemp.com.ua/strotitelnoe_oborudovanie/) are widely known.

NEMP LLC Ukraine, Nikolaev. The products of the NEMP company have such significant shortcomings as the time of delivery of original spare parts and state interest in supporting a domestic manufacturer (state import substitution strategy), as well as limited technological capabilities.

A mobile unit adopted for the closest technical solution is known (see RU Utility Model Patent RU 133463, IPC В28В 3/00, publ. 10/20/2013), made in the form of a vibrating press, intended for use on open areas in the summer and year-round in heated rooms, consisting of a base frame of a vibrating press, equipped with a gear motor, wheels, a vibrating press with a hydraulic power station, a hydraulic distributor, forming equipment (die-punch), loading capacity. Moreover, the base frames of the vibrating press are spatial, a gear motor, a driving wheel, a rotary wheel, a steering gear, a free wheel are mounted in the lower part of the base frame, a hydrostation, a hydraulic distributor, power cylinders, vertical displacements of the matrix matrix spatial frame are installed, and power cylinder, vertical displacement of the spatial frame of the punch. Inside the spatial frame of the base of the vibrating press there is a spatial frame of the matrix, which is connected to the frame of the base of the punch through the rolling friction units and the rods of the power cylinders. In the lower part of the matrix frame, through the vibration mounts, a matrix is mounted with a receiving tray that performs the function of the loading capacity. At least one vibrator is mounted under the receiving tray on the front wall of the matrix. Inside the matrix frame there is a spatial frame of the punch, which is connected to the matrix frame through the rolling friction units and the ram cylinder. In the lower part of the punch frame, on the rails, a punch bracket is placed, onto which a punch is mounted through vibration mounts. At least one vibrator can be installed on the punch. In the design of the vibrating press, spatial frames are used, placed one in the other, having the possibility of vertical movements and interconnected via rolling friction units, which allows you to distribute the loads that arise when using large dies and punches. A drive has been used to move the mobile vibrating press around the site.

The disadvantages of this technical solution are the low productivity of the installation, its ergonomic characteristics, which would guarantee a longer service life, also the disadvantages of this device include the need to manually load concrete mixture components and water into the bunker-mixer, which reduces the productivity of the device and increases the time concrete preparation at the construction site. Another important drawback is the technical characteristics of this solution, when the range of products is limited only to the production of wall stones (cinder blocks) and does not have the possibility of its expansion due to the production of foundation concrete blocks (FBS).

The technical task of the claimed invention is to increase the reliability of operation due to the constructive solution, reduce the cost of manufactured products, since it does not require a mold for each manufactured unit, the drying time of the manufactured product is also reduced due to the fact that its manufacture is carried out by vibrocompressing a semi-dry mixture, and not by casting from liquid concrete.

The technical task is achieved by creating a self-propelled unit for the production of foundation blocks, whose ergonomic characteristics guarantee a longer service life, increasing productivity due to a constructive solution.

The problem is solved by creating a self-propelled installation for the production of foundation blocks, the main part of which is the base of the vibrating press, equipped with a reversible geared motor, wheels, hydraulic power station, hydraulic distributor, forming equipment (die-punch), and loading capacity. The main part, uniting all the working bodies of the installation, is a welded frame, which consists of two parts: a vibrating press frame and a bucket frame. The flanges located at the ends of both parts of the frame, provide the connection of two parts of the frame into a single unit using bolted connections. Before transporting the product, both parts of the frame are disconnected. The vibrating press frame consists of two side parts having a U-shaped profile, and connected in the upper part by a traverse, in the lower part - by a longitudinal channel. The frame of the vibropress is made of channels. In this part of the frame, there is a direct vibropress with a forming tool (matrix-punch) and all the nodes that ensure the formation of blocks. The second part of the frame is designed for mounting the boot bucket (hereinafter - the bucket). The bucket frame consists of two rear bases, interconnected by two longitudinal channels. On each base, the rear are fixed along the body of the bucket hydraulic cylinder, the gear motor and the drive wheel. Two supports are installed on the longitudinal channels, in the brackets of which the bucket supports are fixed on the axles. On each of the parts of the frame, the chassis of two pairs of wheels is located in pairs, with the help of which the installation moves along the working platform during the molding of blocks. On each base of the rear bucket frame, a drive wheel is installed, the drive of which is a gear motor (each wheel is controlled by its own gear motor). A pair of wheels are installed on the vibrating press frame, which are swivel and provide rotation of the installation during operation. The rotary wheel is driven by a hydraulic cylinder. With the help of traction, a rigid connection between the wheels is provided. The traverse is the upper part of the frame of the vibrating press, which provides rigidity to the frame structure and is intended for fastening on it two hydraulic cylinders of the punch holder, the hydraulic cylinder of the matrix and blocks synchronizing the movement of the matrix during molding up / down. Two vertical brackets are mounted symmetrically across the crosshead, in which the bodies of the two hydraulic cylinders of the punch holder are fixed. The rods of the hydraulic cylinders of the punch holder are mounted on the punch holder. During the working strokes of the hydraulic cylinders, the punch holder moves up / down during the molding cycle. The punch holder is located in the upper part of the vibrating press frame and is designed to move the punch up / down during the molding cycle. To mount the punch, frames are used. The frame is a unit designed for mounting interchangeable punch plates, installing a vibrator and placing two boxes. Replaceable punch plates are fixed to the bottom surface of the frame by bolted connections (6 pcs. On each side). The punch is a replaceable element, its size depends on the width of the molded blocks and on their number (one or two). A vibrator is installed in the center of each frame. In each frame, symmetrically mounted on both sides of the box, designed to install and fix the mounting loops in them. Mounting loops are installed before molding and locked with a lock. The frames are made in two versions: one type of frames is used for forming blocks and half blocks with a length of 1189 mm, and the other is used for forming half blocks with a length of 880 mm. Each frame is attached to a pair of racks. In order to protect the frame from vibration, the frame and the rack are pulled together by fasteners through shock absorbers. To fasten the uprights to the punch holder, six pairs of eyes are welded to its bottom surface, into which, depending on the length of the blocks to be molded, the uprights are installed. The design of the installation is such that when loading the matrix with molding sand, the frames should be moved to the side, freeing the cavity of the matrix for loading. The mobility of the connection “rack-eye" is provided by connecting them through the axis. Brackets are welded to the ends of the punch holder, which are connected through a bolt connection to the brackets of the punch holder guides. The considerable length of the guides ensures reliable centering of the punch holder during movement. For easy sliding, polyurethane bushings are installed in the guides, protected by wipers. The guides of the punch holder move along the fixed rods, which are installed in the center of each side of the frame of the vibrating press. Each bar is fixed between the lower base of the vibrating press frame and the traverse. The movement of the punch holder and the punch mounted on it up / down is provided by two hydraulic cylinders of the punch holder. For their synchronous operation, a flow divider is installed on the pressure pipe, which divides the supply flow of the working fluid from the PUNCHON section of the hydraulic distributor into equal parts by flow rate, which enter the piston cavities of the hydraulic cylinders. The flow divider is mounted on the traverse. From the rod cavities of the hydraulic cylinders, the working fluid, through a tee mounted on the drain line, enters the drain in the PUNCHON section of the hydraulic distributor. To ensure a smooth return stroke to the punch holder, a throttle is installed on the line for draining the working fluid from the hydraulic cylinders. Guide rods are installed on the rods in the lower part of the vibropress, on the cone of which removable side walls of the matrix are installed. Two longitudinal walls are attached to the side walls with bolts: the front and the back, which form the matrix. Thus, the matrix is a prefabricated structure in which, by reinstalling the longitudinal front wall, the matrix width changes, which makes it possible to produce blocks with a width of 300 to 600 mm. A removable insert installed in the middle of the matrix divides the matrix into two parts, which allows two blocks to be molded simultaneously. When forming one block, plugs are installed in the installation locations of the removable liner. The size of the molded block along the length is fixed using interchangeable middle liners and their corresponding side, so the matrix can form from one solid block to two blocks at a time. When forming two blocks, the middle liner is installed in the middle part of the matrix; when forming a whole block, the middle liner is not installed, a special plug is installed in its place. Depending on the width and length of the moldable block, the changeover of the punch plates takes place. One vibrator is installed in the center of the front and rear longitudinal walls of the matrix, which transmit vibration to the matrix metal structure, and from it to the moldable mixture, which ensures vibration compaction of the moldable mixture. Moving the matrix guides up / down provides a hydraulic cylinder, which is installed horizontally inside the crosshead. The housing of the hydraulic cylinder of the matrix is mounted on the traverse, and the rod is pivotally connected to the carriage, which moves reciprocally along the channels of the traverse. The carriage is connected to the guide rails of the matrix through the drive chains and the block system. The drive chain tension mechanism provides tension control of the drive chains for synchronous operation of the guide rails. The bucket combines the loading capacity and two bins in which a stock of the molding mixture is created. In the idle position, the bucket is in the lower horizontal position. When the matrix is loaded with the molding mixture, the bucket with the help of two hydraulic cylinders rises up to its highest position, which is limited by the working stroke of the hydraulic cylinder. Cases of hydraulic cylinders are fixed on the frame, and the rod on the body of the bucket. For safety reasons, excluding spontaneous lowering of the bucket when loading the matrix with the molding sand, a hydraulic lock is installed that fixes the bucket in the raised position. The hydraulic lock is mounted on the longitudinal channel of the bucket frame, connecting the pressure and discharge pipelines of the KOVSh hydraulic distributor section and the pipelines of the piston and rod lines of the bucket hydraulic cylinders. Each hopper has a dispenser, each of which opens its own hopper when loading the matrix with molding sand. The operation of the dispensers is provided by two hydraulic cylinders, the rods of which are fixed on the dispensers, and the body - on the bucket body. When the bucket is raised up, the dispenser opens and the mixture is unloaded directly into the matrix. A vibrator is attached to each bunker, which shakes the mixture, ensuring its best descent into the matrix. To protect the bucket body from vibration, the connection of the bottoms of the dispensers to the bucket body occurs through shock absorbers. Two fangs welded to each bunker body (1 piece for each bunker) serve as a pusher: abutting the extreme racks when lifting the bucket up, they take the punch to the side, freeing the matrix cavity for loading. In order to interlock in moving the bucket of the matrix and punch holder, three contactless induction switches (hereinafter referred to as the sensor) are installed. Locks are introduced in order to prevent the operator from mistakenly raising the bucket when the die is raised up or the punch is in the lower position during the molding cycle. Conversely, during the loading process (with the bucket raised), a block occurs in moving the die up or punch down. The sensors are installed in holders welded to the vibrating press frame (2 pcs.) And to the bracket. The sensor is triggered when a metal part enters the contact zone. For this purpose, the matrix and punch are welded according to the flag, the metal part to which the bucket sensor is triggered is the bucket support. On the left side of the vibrating press, on the brackets welded to the vibrating press frame, a pumping station is mounted, which provides the supply of working fluid under working pressure to the hydraulic cylinders of the matrix, punch, dampers, swivel wheel and bucket, as well as its discharge, adjustment of pressure in the hydraulic system, protection against overloads and hydraulic control of the installation.

Technical characteristics of the proposed facility are shown in table 1.

Thus, the combination of features characterizing the claimed object, determines the appearance of such a technical result, which provides a solution to the problems of the proposed technical solution.

The analysis of the prior art shows that the installation is unknown, which is characterized by features identical to all the essential features of this technical solution, which indicates its unknownness and, therefore, novelty.

The main part, uniting all the working bodies of the installation, is a welded frame 2, consisting of two parts: a vibrating press frame and a bucket frame. The flanges located at the ends of both parts of the frame provide the connection of the two parts of the frame into a single unit using bolt connections 41. Before transporting the product, both parts of the frame are disconnected. The vibrating press frame consists of two side parts having a U-shaped profile, and connected in the upper part by a traverse 22, in the lower part - by a longitudinal channel. The frame of the vibropress is made of channels. In this part of the frame is located directly vibropress 1 with forming equipment (matrix-punch) and all the nodes that ensure the formation of blocks. The second part of the frame is designed for mounting the boot bucket 9 (hereinafter bucket). The bucket frame consists of two rear 43 bases, interconnected by two longitudinal channels. On each base, rear 43 is fixed along the body of the hydraulic cylinder of the bucket 10, the gear motor 16 and the drive wheel 15. Two supports 49 are installed on the longitudinal channels, in the brackets 50 of which the bucket supports 45 are fixed on the axles. On each of the frame parts are two chassis pairs of wheels, with which the installation moves along the working platform in the process of forming blocks. On each base, the rear 43 bucket frames are mounted on a drive wheel 15, the drive of which is a gear motor 16 (each wheel is controlled by its own gear motor). A pair of wheels are installed on the vibrating press frame, which are rotary 3 and provide rotation of the installation during operation. The rotary wheel is driven by a hydraulic cylinder 33. A traction 31 provides a rigid connection between the wheels 3. The cross-beam 22 is the upper part of the vibrating press frame, which provides rigidity to the frame structure and is designed to fasten two hydraulic cylinders of the punch holder 17, the hydraulic cylinder of the matrix 32 and the blocks synchronizing movement matrices during molding up / down. Two vertical brackets are mounted symmetrically across the traverse, in which the bodies of the two hydraulic cylinders of the punch holder 17 are fixed. The rods of the hydraulic cylinders of the punch holder 17 are mounted on the punch holder 19. During the working strokes of the hydraulic cylinders 17, the punch holder 19 moves up / down during the molding cycle. The punch holder 19 is located in the upper part of the vibrating press frame and is intended to move the punch 21 up / down during the molding cycle. Frames 24 are used to fasten the punch 21. Frame 24 is a unit for attaching replaceable punch plates, installing a vibrator 20 and placing two boxes 26. Replaceable punch plates 21 are fixed to the bottom surface of the frame 24 by bolt connections (6 pcs. On each side ) The punch 21 is a replaceable element, its size depends on the width of the molded blocks and on their number (one or two). A vibrator 20 is installed in the center of each frame 24. Boxes 26 are mounted symmetrically on both sides of each frame 24 for mounting and fixing mounting loops in them. Mounting loops are installed before molding and locked with a lock. Frames 24 are made in two versions: one type of frames is used for forming blocks and half blocks with a length of 1189 mm, and another is used for forming half blocks with a length of 880 mm. Each frame 24 is attached to a pair of racks 18. In order to protect the frame from vibration, the frame 24 and the rack 18 are pulled together by fasteners through shock absorbers 39. To attach the racks to the punch holder 19, six pairs of eyes are welded to it, depending on the length molded blocks, racks are installed 18. The design of the installation is such that when loading the matrix with the molding mixture, the frames should be moved to the side, freeing the matrix cavity for loading. The mobility of the connection “rack-eye" is provided by connecting them through the axis. Brackets are welded to the ends of the punch holder 19, which are connected via a bolt connection to the brackets of the punch holder guides 8. The considerable length of the guides 8 ensures reliable centering of the punch holder during movement. For easy sliding, polyurethane bushings are installed in the guides, protected by wipers. The guides of the punch holder 8 are moved along the stationary rods 6, which are installed in the center of each side of the frame of the vibrating press. Each rod 8 is fixed between the lower base of the vibrating press frame and the traverse 22. The punch holder 19 and the punch 24 mounted on it are moved up / down by two hydraulic cylinders of the punch holder 17. For their synchronous operation, a flow divider is installed on the pressure pipe, which divides the supply fluid flow from the section PUNCHON of the hydrodistributor 36 into equal parts by the flow rate, which enter the piston cavities of the hydraulic cylinders 17. The flow divider is mounted on the traverse 22. From the rod cavities of the hydraulic cylinder at 17, the working fluid through the tee installed on the drain line, enters the drain in the PUNCH section of the hydraulic distributor 36. To ensure a smooth return stroke to the punch holder, a throttle is installed on the drain line of the working fluid from the hydraulic cylinders 17. On the rod 8 in the lower part of the vibropress, guide matrixes 4 are installed, on the cone of which removable side walls of the matrix 30 are mounted. Two longitudinal walls 46 are attached to the side walls 30 by bolts 29: the front and rear walls, which form the matrix 28. Thus, the matrix is prefabricated structure, in which, by reinstalling the longitudinal front wall, the width of the matrix changes, which allows the production of blocks with a width of 300 to 600 mm. A removable liner 40 mounted in the middle of the matrix divides the matrix into two parts, which allows two blocks to be molded simultaneously. When forming one block, plugs are installed in the installation locations of the removable liner. The size of the molded block along the length is fixed using interchangeable middle liners 40 and the corresponding lateral, so the matrix can form from one solid block to two blocks at a time. When molding two blocks, the middle liner is installed in the middle part of the matrix, the middle liner is not installed when molding a single block, the special plug is installed in its place. Depending on the width and length of the moldable block, the changeover of the punch plates takes place. In the center of the front and rear longitudinal walls of the matrix, one vibrator 27 is installed, which transmit vibration to the matrix metal structure, and from it to the moldable mixture, thereby providing vibration compaction of the molding mixture. The upward and downward movement of the matrix guides 4 is provided by a hydraulic cylinder 32, which is mounted horizontally inside the yoke 22. The matrix hydraulic cylinder body is mounted on the yoke 22, and the rod is pivotally connected to the carriage 47, which moves reciprocally along the channels of the yoke 22. The carriage 47 through the drive chains 7 and the system of blocks 34 is connected to the guides of the matrix 4. The tension mechanism of the drive chains provides the tension of the drive chains for their synchronous operation of the guide matrix 4. The bucket 9 combines gruzochnuyu container and two hoppers 52, which creates a supply of the moldable mixture. In the idle position, the bucket is in the lower horizontal position. When the matrix is loaded with the molding mixture, the bucket 9 with two hydraulic cylinders 10 rises up to its highest position, which is limited by the working stroke of the hydraulic cylinder 10. The hydraulic cylinder bodies 10 are mounted on the frame 2, and the rod on the bucket body.

For safety reasons, excluding spontaneous lowering of the bucket when loading the matrix with the molding sand, a hydraulic lock is installed that fixes the bucket in the raised position. The hydraulic lock is mounted on the longitudinal channel of the bucket frame, connecting the pressure and discharge pipelines of the KOVSh hydraulic control valve section and the pipelines of the piston and rod lines of the bucket hydraulic cylinders 10.

Each hopper 52 has a dispenser 12, each of which opens its own hopper when loading the matrix molding sand. The operation of the dispensers is provided by two hydraulic cylinders 35, the rods of which are mounted on the dispensers, and the body on the body of the bucket 9. When the bucket 9 is raised up, the dispenser 12 is opened and the molding mixture is unloaded directly into the matrix. A vibrator 11 is attached to each hopper 52, which shakes the molding mixture, providing its best descent into the matrix. To protect the bucket body from vibration, the connection of the bottoms of the dispensers to the bucket body occurs through shock absorbers 13. Two fangs 42, welded to each housing of the hopper 52 (1 piece for each hopper), act as a pusher: abutting against the extreme racks 18 when lifting the bucket up, take the punch aside, freeing the cavity of the matrix for loading.

In order to interlock in moving the bucket, matrix and punch holder, three proximity induction switches (hereinafter referred to as the sensor) are installed. Locks are introduced in order to prevent the operator from mistakenly raising the bucket when the die is raised up or the punch is in the lower position during the molding cycle. Conversely, during the loading process (with the bucket raised), a block occurs in moving the die up or punch down.

The sensors are installed in holders welded to the vibrating press frame (2 pcs.) And to the bracket 50. The sensor is triggered when a metal part enters the contact zone. For this purpose, the matrix and punch are welded according to the flag, the metal part to which the bucket sensor is triggered is the bucket support. On the left side of the vibrating press, on the brackets welded to the vibrating press frame, a pump station 14 is mounted, which provides the supply of working fluid under working pressure to the hydraulic cylinders of the matrix, punch, dampers, swivel wheel and bucket, as well as its discharge, pressure regulation in the hydraulic system, protection against overloads and hydraulic control of the installation.

Works self-propelled for the production of blocks as follows.

Turn on the pumping station by pressing the start button of the START pump station. Set the hydraulic distributor handles in turn all the working elements of the installation in the initial position: punch - in the upper position, raise the matrix by 5-10 mm and place a piece of polyethylene under it, exceeding the matrix by 15-20 mm, then move the matrix down onto the polyethylene, bucket - in the lower position.

Load the molding sand into the bucket by any technological transport (loading volume ~ 2.6 m ³ ), while trying to load it closer to the hoppers. The ladle is lifted by the bucket control handle, while the molding mixture moves from the bucket loading cavity to the hopper 52. Check the position of the frames 24, which with their fangs 42 should be moved to the side, releasing the matrix loading cavity 28. Using the DOSER control knobs, open the batchers of each hopper, while simultaneously pressing control button VIBRATOR OF DISPENSER 57, and fill the matrix with molding sand. Close the hopper dispensers. Vibro-lay the forming mixture in the matrix. Turn on the control button VIBRATORS OF THE MATRIX 56 for 3-5 seconds. The mixture is vibro-compacted and the stones are preformed in the matrix. Turn off the vibrators. If necessary, reload the moldable mixture into the matrix. Install the mounting loops. Installation loops are installed with the punch deflected when the bucket is at the top. Install the mounting loops on the side of the punch 21 and fix them in the locks. After installing the mounting loops, the BUCKET control handle moves the bucket to the lower position. The PUNCH control knob moves the punch down until the mounting loops touch the surface of the moldable mixture and press the control button PUNCH VIBRATORS 55, introducing the mounting loops into the molding mixture, continue to move the punch down the PUNCH control handle until it stops with bolts 23. Press the CONTROL MATRIX button and continue forming blocks in a given mode until a sound of free vibration of the form (increase in sound) appears. Turn off the VIBRATORS control button. Release the mounting loops by removing the lock from the locks of the mounting loops. Forming molded blocks. The MATRIX control knob lifts the matrix up until the blocks are completely released (lift the matrix up without stopping), while the punch should remain in the lower position, pressing the blocks to the platform. At the initial moment of formwork, the matrix is lifted when the hydraulic cylinders 32 are running slowly. The punch is raised to its initial upper position with the PUNCH control handle. By pressing the MOTION control button, the installation is moved to the required step, and the work cycle is repeated. To change the direction of movement of the installation, the WHEEL control knob sets the movement of the installation in a given direction.
