DEVICE FOR FINISHING SURFACE OF REINFORCED CONCRETE PRODUCTS,. containing a self-propelled portal, a frame mounted on it with spring-loaded levers mounted on it. SU ,, .. 1Q21625 A 3

Description

The invention relates to devices for finishing freshly molded surfaces of concrete and reinforced concrete products.

A device for finishing the surface of reinforced concrete products is known, which contains a self-propelled portal, a frame mounted on it with mounted spring-loaded levers on which the smoothing roller is rigidly fixed, and a frame-lifting drive mounted on the portal.

A disadvantage of the known device is the inability to control the constancy of the pressure during the filling process, which reduces the quality of the surface finish of the product.

The purpose of the invention is to improve the quality of the finish by creating an optimal pressure roller to the surface of the product ..

The goal is achieved by the device for finishing the surface of reinforced concrete products, containing a self-propelled portal, a frame mounted on it, with mounted springs on it, on which the smoothing roller is fixed and the frame lifting drive installed on the portal, is fitted with a frame in the middle part a collar connected to a frame lift drive, mounted on the portal with brackets with vertical cuts, in which are placed the ends of the frame, made in the form of rocker arm, and the levers are attached to romysle, and their springs are provided with rollers / in contact with the portal.

Fig. 1 shows a machine for smoothing concrete products, general view, Fig. 2, a sectional view in Fig. 1; figure 3 - section bb in figure 2; figure 4 - section bb In figure 2; figure 5 is a section of the G-Gn figure 2; on fig.b - adjustment scheme. nor the pressure of the working body on the surface to be laid.

The machine contains a self-propelled gantry 1 with a drive for its movement, a smoothing roller 2 with a drive for its rotation 3, and a suspension system aatf face, made in the form of mounted with the possibility of raising and lowering the rocker arm 4, to which the levers 5 are attached, carrying the smoothing roller 2. Drive 3 rotation , the roller 2 is on the levers 5. The yoke 4 is placed in the slots of the brackets –b of the portal 1 and through the yoke 7 and the finger 8 is connected to the yoke 9 of the mechanism 1O, lifting and lowering the rocker arm 4. The levers 5 through the rollers 11

unlocked on the vertical plane of the portal 1. The rollers 11 are spring-loaded springs 12. In addition to the roll-down roller 2, the portal 1 also features a trowel disk 13 with its rotational drive 14, a mechanism 15 for horizontal movement of the disk 13 perpendicular to the axis of movement of the portal

1 and a disc movement mechanism 16.

The operation of the proposed machine is as follows.

Before starting work, the drive mechanism 10 of the vertical movement of the roller 2 is turned on with its setting at a level corresponding to the level of the product surface being treated. Next, the rotational drive 3 is turned on. 2 and the portal travel drive and the smoothing of the open surface of the product 17 molded into the mold 18 is performed. The smoothing is carried out by re-rolling the roller 2 along the surface of the product 17.

. At the end of the smoothing roller

2 if necessary, the grinding of the machined surface involves turning the disk 14 of the disk 13 and, when the latter passes over the surface being treated, it is finally ground by re-using the machine 16 over the product 17. The moving disk 13 horizontally is moved by the mechanism 15, and vertical by the mechanism 16.

In the process of smoothing the pressure of the roller 2 on the surface to be treated is equal to the force generated by the weight of the roller 2 and the levers 5, reduced by the amount of compressive force of the springs 12, rollers 11, taking into account the ratio of the arms of the levers 5. By adjusting the amount of lifting-lowering of the bore 4 by means of mechanism 10 in the process smoothing, the operator has the ability to smoothly change the pressure of the roller 2 on the surface of the workpiece, without stopping the smoothing process.

By performing the suspension of the smoothing roller in the form of a yoke on which the roller is mounted, and fixing the levers hingedly by means of a yoke with a vertical thrust, the specified pressure of the smoothing roller on the treated surface is maintained, and resting the levers on the portal by means of supporting spring-loaded rollers ensures a smooth running effect. on the smoothing surface.
