Description

S sQ

The invention relates to industry, building materials / in particular. devices for stripping boards of forms of building products.

A device for manufacturing reinforced concrete products is known, comprising a bed, outer shields, a core and a formwork and assembly mechanism.

. A device for stripping and assembling molds is also known, comprising a portal on which pivot arms are mounted, a lever pivot drive in the form of power cylinders and a lifting-lowering mechanism 0).

The closest to the proposed technical essence and the achieved result is a device for opening and closing the sides of the molds containing pivoting levers pivotally connected to the rod, and a pivoting drive of levers in the form of power cylinders, the rods of which are pivotally connected to the levers (2).

A disadvantage of this device is that. that it can be used to open the longitudinal or end walls only with a constant size between the stop axes on the mold, since when changing to a different size, it requires CO

with change the width of the rod. A disadvantage is also the inability to fix the bar relative to the shape.

The purpose of the invention is the expansion of technological capabilities.

This is achieved in that in the device for stripping the sides of the mold on the self-propelled portal using flexible links, a traverse made in the form of a hollow beam is suspended, inside of which there are sprockets with carriages placed between them with grippers for interacting with the longitudinal sides of the form, and sprockets. covered by a closed circuit connected by each of two parallel branches to one of the carriages, and one of the latter is connected to a separate power cylinder mounted on the traverse. The yoke at the ends of the hollow beam is provided with horizontal movement limiters designed to interact with the guides on the posts of the portal ..-. . . .

In FIG. 1 shows a general view of the device in a transverse directional shape; Fig. 2 shows the successive positions of the traverse when stripping the transverse sides of the mold; in Fig.Z is a view of the crosshead from above.

. The device for stripping the sides of the mold comprises pivot arms 1 for interacting with the transverse sides. 2 forms pivotally connected to traverse 3, a drive for turning levers 4 in the form of power cylinders, the rods of which are pivotally connected to levers, a cable-block mechanism for raising and lowering 5 traverses,. including a chain 6 thrown over the deflecting sprockets 7, and a self-propelled portal 8, on which a yoke is suspended by means of flexible connections.

Traverse 3 is a hollow beam, inside which chain sprockets 9 are installed with carriages 10 located between them with grippers 11 for interacting with the longitudinal sides 12 of the mold. Guides 13 are also made on the traverse for moving the carriages 10. The sprockets 9 are surrounded by a closed chain 1.4 connected to each of two parallel branches with only one of the carriages 10. An arm 15 is mounted on one of the carriages, which is pivotally connected to one end of the power cylinder 16, the other end of which is attached to the traverse 3. The grips 11 of the carriages 10 are located in one common vertical plane.

At the ends of the hollow beam of the beam 3 there are limiters 17 of its movement in the horizontal plane, made

to interact with the guides 18 on the racks of the portal 8.

On the sides of the form 19 should be provided pockets 20, consisting of two

cheeks and a persistent finger between them. Opposite pockets on the longitudinal sides 12 should be in the same vertical plane and at the same height, and the distance between this plane and the nearest end of the article should be constant for all shapes. On the transverse sides 2 pockets 20 are located in the middle part. Pockets on the longitudinal sides 12, if there are grips 11 in them,

are abutments for fixing the yoke 3 on the mold in the longitudinal direction. One end of each pivot arm is operative and can interact with the thrust finger of pocket 20 on the transverse

board 2. The device is controlled by an operator located on site 21 from the console 22.

The device operates as follows.

a) After the filing of the mold (or trolley mold) 19 in the operating zone of the device, the latter is fed to one of the ends of the mold 19 so that the plane of the grippers of the lifting beam 3 coincides with the plane

the speed of the pockets on the longitudinal sides 12 of the form (plane 1 in FIG. 2). The traverse must be in the raised position, its left-hand swing arm 1 is in the working position, and the right-hand lever is turned to the idle position. The carriages 10 are divorced so that their grabs 11 are able to fall into the pockets of 20 longitudinal sides 12.

b) The traverse 3 is completely lowered onto the mold 19 until it touches the sides or the product, while the grips 11 of the carriages 10 enter the pockets 20 of the longitudinal sides 12, and the working part of the left lever enters the pocket 20 of the left transverse side 2.% c) Including the power cylinder 4 left

lever 1 to retract the rod, the transverse side 2 is opened. At the end of the stroke, the lever 1 is pulled out of the pocket

twenty. /-..;

Thereafter:.. .

. d) The traverse 3 is lifted up and the device is moved to the second transverse 1 st side 2, again combining the plane of the traverse grips with the plane of the pockets on the longitudinal sides (plane P on

figure 2). The right rotary lever 1 turn-. they are in the working position, the left one remains inoperative.

d) Lower the traverse 3 to the form 19, making sure that the grips of the carriages 10 and

the capture of the pivot arm 1 fell into the corresponding pockets 20.

f) The transverse side 2 is opened with the right pivoting arm 1. After completion of the stroke of the pivoting arm, the carriages 10 with grippers 11 are moved to the sides, opening the longitudinal sides 12.

When non-simultaneous separation of the sides from the product, the beam 3 is displaced towards the open side. In this case, the opening force is sensed by the device portal 8, into the guides 18 of which the travel limiters 17 of the yoke 3 abut.

With great effort stripping the longitudinal sides 12, the latter can be opened in two steps: first, as described in the paragraph, tear off one end of the side, and then you need to return the device with traverse 3 to plane 1 and. the sliding here of the carriage 10, finally open the sides.

The possibility of opening no longitudinal sides 12 beyond the middle is also excluded, for which purpose it is necessary to provide pockets in any, specific place along the length of the side. .

The application of the proposed device provides advantages :.

1. Forms can be of different sizes in length, width and height (in certain sizes);

2. The device can itself move along the shape, i.e. not associated with a tap;

3. The traverse with captures is automatically fixed on the form;

-.-.-

4. The device can be applied in the case when any or any of the sides are rigidly attached to the pallet form. .
