Description

The invention relates to the construction, namely, to machines for carrying out plastering work - applying a plaster layer with a smooth surface.

The purpose of the invention is to improve the quality of finishing and expanding technological capabilities by ensuring the distribution of materials under pressure.

FIG. 1 shows the machine, a general view; in fig. 2 - - equipment, general view; in FIG 3, a plasterer's machine at bor durokladchiki; in fig. four . the same, in the technological equipment of factory production of lengthy profile products from plastic masses.

A plastering machine for distributing plastering solutions and other plastic materials can be installed on a vehicle that includes base chassis 1, rod 2 and carrier 3. Carrier 3 is a carriage with an individual electric drive (not shown) and can move along rod 2, which spreads between the floor and the ceiling. The rod 2 is parallel to the outer plane of the plaster layer. The stucco solution is fed to the distribution unit 4 through a flexible pipe 5 with a mortar pump 6.

The profiling device 7, the front wall 8 and the feeding device 9 form the distribution unit 4. The front wall 8 is attached to the forward edge of the profiling device 7 in the direction of movement at an angle to this direction.

The height of the wall 8 is less than or equal to the thickness of the layer of material being laid

The feeding device 9 is made in the form of a pipe with a slit. Slot length

0 The distribution unit 4 is connected to the carriage 3 through a movable connection — an additional carriage consisting of two mutually movable parts 10 and 11. The part 10 of the carriage is connected to the profiling device 7 of the distribution unit

5 of the unit 4, part 11 is connected to the carriage 3. Part 10 of the additional carriage is made in the form of a cart with twin wheels. Part 11 of the additional carriage is made in the form of a frame with directional pairs. The wheels of the cart encompass these guides on both sides. Parts 10 and 11 of the additional carriage are interconnected by an elastic element 12. In addition, on one of the parts, for example, part 11 connected to the carriage 5 and 3, a system for controlling the set value of the elastic resistance consisting of the controller (actuator) 13 of the system is installed. moving the carriage 3, and the pressure device 14 of the actuator 13 on the part 10 of the additional carriage.

Instead of the actuator 13, any known proportional displacement transducer may be installed.

The control device 13 has a scale 15 for adjusting for a given deformation of the elastic element 12. The relative position of the actuator 13 and the pressure device 14 can vary in the direction of movement of the additional carriage.

Scale 15 is designed to adjust the distribution unit 4 at a given pressure of the solution on the treated surface. The pressure depends on the type of solution and its fluidity.

The profiling device plays the role of a mobile formwork and is intended to form a strip of the stacked layer of mortar and smooth its surface. The profiling device 7 is made in the form of a plate with a side wall on the right along the movement of the distribution unit 4. The profiling device 7 is open at the back and on the left during the movement. The profiling device 7 does not have a left side wall along the side movement, which allows seamless joining of two adjacent stacked solution strips.

The height of the side wall is such that it completely or partially covers the cross-sectional area of the profiling material. If there is a gap between the side wall of the profiling device 7 and the surface to be treated, the applied solution, penetrating the gap, creates a locking roller directly behind the side wall. This roller prevents further leakage of the solution from under the side wall of the profiling device 7.

The front wall 8 of the profiling device 7 senses the pressure of the solvent injected by the feeding device 9 into the space bounded by the non-plastered wall and the distribution unit 4.

The forces acting on the wall 8 are not balanced, and when they reach a certain value, the distribution unit 4 begins to move.

The movable joint consisting of two mutually movable parts 10 and II allows the distribution unit 4 to move relative to the carriage 3.

In order to ensure adhesion of the solution to the material of the treated surface, to fill the volume of the profiling device 7, and also to move, some excess pressure of the solution in the cavity of the profiling device 7 is necessary. This pressure is achieved with a certain deformation of the elastic element 12 that occurs at a certain displacement from the initial position of the profiling device 7 relative to the carriage 3.

In order that the displacement does not increase above the set value, the carriage 4 turns on. The starter 13 and the pressure device 14 are intended to turn on the electric drive of the carriage 3 when the mobile part 10 of the additional carriage is displaced relative to part 11 by a predetermined value.

Plasteural machine works as follows.

A setting is made to a predetermined pressure by moving the actuator 13 on a scale 15 to a position in which its activation corresponds to a certain deformation of the elastic element 12 and, consequently, to a given pressure of the solution. Then, with the help of the carriage 3, the distribution equipment moves along the rod 2 to the extreme upper position and stops. Next, the plant pump 6 is turned on and the plaster solution through the flexible pipe 5 flows through the feeding device 9 into the space bounded by the plastered wall and the profiling device 7 with the front wall 6. As this space is filled, including all the cavities on the wall, the pressure of the solution increases. The pressure forces acting on the front wall 8 of the distribution unit 4 are not balanced by the pressure forces on the opposite side, and the unit begins to move forward (in this case it is a movement from top to bottom) with the stationary carriage 3. As the movement proceeds, the elastic element 12 gradually expands. This leads to an increase in the resistance to movement of the aggregate 4 and an increase in the pressure of the solution in its cavity. The growth of the solution pressure occurs until the pressure device 14 switches on the starter 13 of the carriage movement system 3.

If the speed of the carriage 3 is greater than the speed of movement of the distribution unit 4. A moment will come when the pressure device 14 lags behind the actuator 13, the drive system of the carriage 3 turns off and it stops. After some time, the pressing device 14 will catch up with the starter 13, and the carriage drive system 3 will be turned on again. Further, these actions are repeated, and the carriage 3 moves at an average speed equal to the average speed of the distribution unit 4

Throughout the entire path of movement of the distribution unit 4, the solution pressure is kept close to the target, i.e. the carriage 3 moves in accordance with the commands of the actuator 13 with a limited lag and advance of the distribution unit 4 and, therefore, the tension of the elastic element 12 also fluctuates boundedly, the same happens with the pressure of the solution.

There are other options for using distribution equipment. For example, distribution equipment can be used in machines for setting concrete curbs on highways. In this case, the self-propelled tracked chassis 16 has a distribution unit 4, which is profiled

device 7 which corresponds to the road curb profile. The adjustment of the speed of the machine is made depending on the speed of movement of the distribution unit 4.

The principle of operation in the manufacture of road curbs is the same as in the application of plaster, only the stencil is laid on a horizontal surface.
