Description

The invention relates to the field of ground construction, in particular, to devices for the manufacture of concrete and reinforced concrete products by continuous molding on long stands.

It is known from the state of the art to manually insert a sling rod into concrete (https://kblok.ru/blog/jbk-9). The worker, using a knife, cuts through the concrete above the void of the slab, pushes the cut concrete to the sides with a trowel and manually inserts the sling rod into the slab.

However, the low accuracy of the position of the sling rod horizontally and vertically leads to uneven tension of the slings when lifting the slab and its possible destruction and the need for two workers to perform this work; the initial manual placement of the sling rod (SS) along the slab at the point of implementation on both sides.

The technical problem is to create a device for installing a sling rod into a reinforced concrete slab before the concrete hardens, reducing labor costs and creating a comfortable working environment.

The technical result consists in increasing the accuracy of installing the sling rod in a reinforced concrete slab until the concrete hardens along one line and equalizing the tension of the slings.

The technical result is achieved in that the machine for installing a sling rod into a reinforced concrete slab before the concrete hardens, according to the solution, contains a frame configured to move along the reinforced concrete slab, a control unit placed on it, two blocks for forming holes on opposite sides of the reinforced concrete slab and two implementation blocks sling rods into a reinforced concrete slab, configured to extend the sling rods and install them in the side parts of the reinforced concrete slab, to be automatically loaded with the next sling rods for pushing the previous sling rods into the side parts of the reinforced concrete slab to a given depth in the holes.

The machine for installing a sling rod into a reinforced concrete slab before the concrete hardens contains a frame 1 configured to move along the reinforced concrete slab 9, a control unit 4 placed on it, two blocks for forming holes 2 on opposite sides of the reinforced concrete slab and two blocks for introducing 3 sling rods 6 into the reinforced concrete plate 9 (Fig. 1-2). The implementation unit 3 is configured to extend the SS 6 and install it into the side of the reinforced concrete slab 9, to be automatically charged with the next SS 6 to push the previous sling rod into the side of the reinforced concrete slab to a given depth into the hole.

Well formation block 2 consists of a metal frame with a casing covering the top frame (Fig. 2). A gearbox for linear movement of the knife 19 is attached to the frame on top. A rectangular knife 16 is attached to the gearbox rack, in the form of a box, having wide and narrow sides according to the required size of the hole in the concrete 9. The knife is moved down and up by the motor 18 through the gearbox 19. The position of the knife is at the top is controlled by a knife position sensor 12, mounted on the block frame from above. Inside the knife, a guide axis 20 and a screw 15 are fixed on bearings on the narrow sides. The blade 11 is held on the axis 20 and the screw 15. The blade movement motor 13 rotates the screw 15 and moves the blade 11 inside the knife. The position of the blade 11 is controlled by a blade position sensor 21, mounted on the narrow side of the knife 16 (Fig. 3-4).

The implementation block 3 consists of a metal base on which two mechanisms are located: the first is for charging the SS, the second is for horizontal movement of the SS (Fig. 5-7).

The CC charging mechanism is designed to install one CC in working position 25 (lowest) and consists of a motor with a charging reducer CC 5 rigidly fixed to the base. The shaft of this gearbox rotates two gearboxes 23 with gear wheels 17, which dose the CC 6 feed during their rotation. The presence of a charged CC in the working position 25 is controlled by two CC position sensors 10, mounted on the base on the side of the CC.

The horizontal movement mechanism of the CC is fixed on the base and is designed to move the CC forward and backward perpendicular to the side wall (part) of the reinforced concrete slab and consists of two rubberized guide rollers with a shear 7 inside the magazine 24 and two rubberized guide rollers without a shear 8 outside the magazine 24, rotating four 22 motors mounted above the rollers in a vertical position. The horizontal position of the SS is controlled by sensors 10. Before installing the SS 6 into the working position 25 by the SS charging mechanism, rubberized rollers with a cut 7 are installed with a cut inside the magazine 24 according to the roller position sensors on the cut 14.

The device works as follows.

All movements of the mechanisms and their position are controlled by control unit 4. The machine operator moves the machine on rails along the plate, controls the presence of the CC in the magazine 24 and gives a command to install (implement) the CC by pressing a button or this happens automatically, depending on the operating mode of the machine and the option execution.

The machine moves along the reinforced concrete slab on rails (Fig. 2). The hole-forming unit lowers the knife down and cuts a hole in the reinforced concrete slab until the concrete above the void hardens; the cut concrete falls down and is moved apart across the void by a spatula in different directions. The insertion block extends the SS and installs it up to the wall of the knife, the knife wall supports the concrete from chipping, the knife rises above the SS, the insertion block pushes the first SS to its edge and is automatically loaded with the next SS, which pushes the first SS to the end to a depth of 0.5 cm from the edge of the plate and returns back, the machine is set to its initial position - the knife rises up, the blade is set in the middle (Fig. 8).

In the initial position, the knife 16 is located above the plate 9, its position is controlled by the sensor 12, the blade is in the middle of the knife, CC 25 is located between the guide rollers 7.

After receiving a command from the control unit 4, the knife is lowered down by the engine 18 through the gearbox 19, it cuts a hole in the reinforced concrete slab 9, the blade cuts the cut concrete in half, moves forward by the engine 13 along the screw 15 and moves half of the cut concrete along the void in the slab 9, the blade returns back to sensor 21 and moves the second half of the cut concrete along the void in slab 9, completing the hole arrangement, rollers 7 and 8 begin to move the SS 25 forward until it stops at the knife 16, the knife keeps the concrete from chipping, the knife 16 rises up above the SS 25 by 5 mm and the CC is introduced to the edge of the implementation block 3, the movement of the sling rod 25 is controlled by sensors 10, the guide rollers 7 are installed in the initial position with cuts inside the magazine 24 according to the sensors 14, the engine with the gearbox 5 begins to rotate the gear wheels 17 and they lower the second sling rod 6 between the slices guide rollers 7 before the sensors 10 are triggered, guide rollers 7 and 8 move the second sling rod 25 forward and it pushes the first sling rod to the end to the required (specified) penetration depth and returns back to the implementation block, the knife 16 rises up to the sensor 12 and the blade 11 moves to the middle of the knife, the second hole formation block 2 and the insertion block 3 work similarly, the machine’s operating cycle is completed (Fig. 9).

The present invention is not limited to the above-described embodiment and can be subject to various modifications and changes in the size and operating sequence of the machine mechanisms, which does not deviate from the essence of the invention.
