Description

2. A device according to claim 1, characterized in that on the eccentric axis, a double-arm lever with a longitudinal groove connected to a pivoting lever is mounted on the eccentric axis.

3. The device according to Claims 1 and 2, in that the two-armed lever is connected to the pivoting lever by means of a fork, the end of which is installed in the longitudinal groove of the two-armed lever.

The invention relates to the construction, in particular to the production of reinforced concrete products in forms. A lock for connecting the sides of the mold is known, which contains one on the side of the spring-loaded lever, which cooperates with a stop fixed on the other side, and the lock is provided with a movable bar with a protrusion, guides and fork, and the movable bar is located above the lever in direction. on the horizontal plane of this bead, it interacts with the sockets made on the other side, and the plug is fixed on the spring-loaded lever in the place of the swivel unit and covers the protrusion of the bar C13. The disadvantages of this device are design complexity and non-maintenance convenience. The closest to the proposed is a device for closing and opening the sides of the mold mounted on a pallet, containing a vertically rotatable lever with a figured notch in contact with the stops 2. A disadvantage of the known devices is the inconvenience of its maintenance due to the large number of hinge joints . The purpose of the invention is to improve the service. The goal is achieved by the fact that the device for closing and opening the sides of the mold installed on the pallet, containing a lever with a figured cutout in the vertical plane that contacts the stops, is equipped with rotary levers with eccentric heads, installed with console stops, in contact with the latter, fixed on the pallet with a bracket, on which on the eccentric axis there is a pivot arm, made with protrusions-stops in contact with additional levers, and in places contact with stops -. with facets arranged at right angles and WEDGE-forming Moreover ustanovle.ny additional pivot arms at the nearest to the end where boron pivot arm at an acute angle to its longitudinal axis. At the same time, on the eccentric axis, a double-arm lever with a longitudinal groove is mounted on the eccentric axis, connected to the pivoting lever by means of ilka, the end of which is installed in the longitudinal groove of the two-armed lever. FIG. Figure 1 shows a proposed form with a device for closing and opening all sides, a common zid; FIG. 2 — node I in FIG. IJ in FIG. 3 is a section A-A in FIG. 1. FIG. 4 is a view B in FIG. one ; FIG. 5, view B in FIG. four; in fig. b - a fragment of the assembly of the device in axonometry; Fig.7 - section GGD of Figs. FIG. 8 is a section d-d in FIG. 7) FIG. 9 is a section E-E of FIG. 7. Installed on the pallet 1 forco folding sides 2 are interconnected by a device that contains pivot levers 3 located at an angle of 45 ° to the horizontal in plan. Each lever 3 has a figured cutout in the shape of a hook 4, and has right-angled edges 5, forming a wedge. On the pivot arm 3 mounted on the axis x 6 additional pivot arms 7 with eccentric heads .8, which are contiguity-. They are mounted with supports 9, which are attached to the borg 2. The pivoting lever 3 is mounted on the eccentric axis 10, which is located in the sleeves 11 and 12 on the bracket 13, which is closed on the pallet 1. In the middle part, the pivoting lever 3 has a longitudinal groove 14, in which Axis 10 has its sleeve 15 with edges. The edges of the sleeve 15 cover with their figure cutout 16 (Fig. 6) a double-arm lever 17, made with a longitudinal groove 18, and on its axis 19 a fork 20 mounted on the pivot arm 3 is mounted. The axis 19 is fixed by a washer 21 and a cotter pin 22 (Fig. 6 ). The free end of the swivel rod is hollow and has a detachable extension 23. The rotary lever 3 has projections 24 d; r1 contact with additional levers 7. The bracket 13 has an eccentric stop 25 for fixing the lever 3 in the off position (. Fig. 3). The levers 7 are fixed on the axles x 6 by the spring washer 26. The pa6oTai9T device is next. The levers 3 are set in the lower position on the eccentric stops 25 (Fig. 3) and then two adjacent bopts 2 are raised and fixed in the closed position by turning down the additional levers 7 with the eccentric head 8 (Fig. 4). In this case, the eccentric heads 8 of the levers-7, acting on the console stops 9, press the adjacent beads 2 to each other. After that, they close and fix with the levers 7 the remaining two sides 2. The mold is ready to form the product. After the end of the product, the bead 2 is unlocked by means of levers 7, which rotate the yoke and thereby release the console ynoix 9 from the action of eccentric heads 8 and 7. Then turn up the levers 3 by extension cords 23. At the same time, hook 4 with its faces 5, forming wedge. interacts on console supports 9 and spreads them. When each lever 3 is lifted, the fork 20, its neighbor, with its end moves in the longitudinal groove 18, moving the two shoulders {shchag 17, which rotates the sleeve 15 with faces, respectively,; and the eccentric axis 10. The eccentricity value e provides the hook 4 and, consequently, of its faces 5 when the stops are moved 9. Due to this, the sides 2 are opened with their separation from the finished product r i. simultaneous dismantling of the product. In order to avoid emergency operation when the sides of the mold open, when the eccentric heads 8 of the levers 7 are not brought out of contact with the stops 9, on the swivel heads 3 there are protrusions-stops 24 which, when turned up, forcefully rotate the levers 7, freeing the stops 9 from the eccentric heads 8 , which increases the reliability of the device. Thus, the proposed device is convenient to operate. And an additional stripping mechanism is not needed for spreading the product.
