SU1364477A1 - Locking device for table vibrator - Google Patents

Abstract

This invention relates to the manufacture of precast concrete and reinforced concrete products. The goal is to enable the use in the building materials industry of forms with the location of cap bolts at several levels. This is achieved by the fact that in the locking device of the vibrating plate, the I-pillar is made with interlocked vertical guides 5. Elastic tape 3 is made with counter load 6 and rigid end 7 and elastic intermediate 8 stops with electromagnetic grippers 9 fixed on its idle and working branch x . Counterweight 6 and rigid end stop 7 are contacted by means of support rollers with vertical guides 5 of rack 1. 8 Il.

This invention relates to the manufacture of precast concrete and reinforced concrete products.

The aim of the invention is to provide the possibility of using molds with the location of the cap screws at different levels.

FIG. 1 shows schematically the locking device of the vibron table, general view; in fig. 2 is a view A of FIG. one; in fig. 3 - section B - B in FIG. one; in fig. four -

Form 11 with fixed locks is lowered onto the movable frame 2 of the vibrating plate. In this case, the lower nut 12 of the cap bolt 13 interacts with the electrically-controlled electromagnetic clamp 9 of the end stop 7 and moves the latter downwards, while the elastic intermediate stop 8 passes to the working branch of the elastic band 3 and interacts with the other 12 nut located above

Section b-B in FIG. one; in fig. 5 - cut Yu cap bolt 13.

YY in FIG. four; in fig. 6 - section Д-Д Thanks to this, the side locks of the mold are simultaneously locked

FIG. four; in fig. 7 is a section E - E in FIG. four; in fig. 8 — node I in FIG. four.

Claims (1)

The fixture of the vibroplatform consists of a rack 1 mounted. on the movable frame 2 of the vibrating plate, the elastic band 3, the envelope of the guide block 4, fixed in the upper part of the stand 1, which is made with vertical-Hall pairs blocked in pairs, located at different levels. Invention Formula The locking device of the vibroplatform containing the rack mounted on the last frame with the guides 5 installed in its upper part, and the elastic tape 3 - 20 the Shchy block and its elastic envelope with its idle and working branches x corresponding to the counterweight 6 and a rigid end 7 and an unary intermediate 8 stop with electromagnetic grippers 9, with the counterweight 6 and the hard end stop 7 in contact with the vertical guides 5 by means of the support rollers 10. The locking device vibroplatform works as follows. 25 a tape in contact with the surface of the nut of at least one cap bolt of the form, characterized in that, in order to enable the use of molds with the arrangement of cap bolts on several levels, the stand is made with interlocked vertical guides, elastic tape-mounted on it idle and working branch x respectively counterweight and Before installing form 11 on the movable, rigid end and elastic intermediate frame 2 vibrating plates, a rigid end stops with electromagnetic gripping under 7 under the action of a counter load with 6 tons, with the counter load and rigid end in the extremely upper position, the end stop is in contact by means of support- elastic intermediate stop 8 - on non-rollers with vertical directions of the slender branch of the elastic tape 3. by means of stanchions. Form 11 with fixed locks is lowered onto the movable frame 2 of the vibrating plate. In this case, the bottom nut 12 of the cap bolt 13 interacts with the electromagnetic clutch 9 of the end stop 7 and moves the latter down, and the elastic intermediate stop 8 passes to the working branch of the elastic tape 3 and with its electromagnetic gripper 9 interacts with the other coupling bolt 13. ll located on different levels. Invention Formula The locking device of the vibroplatform, containing the rack mounted on the last frame on the moving frame with the guide block installed in its upper part and the flexible envelope around it a tape in contact with the surface of the nut of at least one cap bolt of the form, characterized in that, in order to enable the use of molds with the arrangement of cap bolts on several levels, the stand is made with interlocked vertical guides, elastic tape-mounted on it idle and working branch x respectively counterweight and eleven Lx 1 / f 8 P Vida 1I Phage. 2 i3, 5-B 8 Fig.Z Yr FIG. five /////////////////, , V / 7 / FIG.
