Description

one

The invention relates to trunnion throwing devices and can be used to treat the surfaces of building structures with various viscous mixtures, for example concrete, that are enclosed for throwing into a sacrificial shell.

A device for the throwing of viscous concrete mixes is known, which includes mobile means on which a rod with a cylindrical container mounted on it is installed, the lateral surface of which is made in the form of barrel chambers, which are closed after introducing solid, gaseous explosives and concrete mixture into them, crushable covers, and explosive blasting systems in chambers 1J.

The disadvantage of this device is its limited use, the impossibility of processing vertical surfaces.

Closest to the present invention is a device for throwing, including a support, mounted on it with the possibility of rotation in the vertical plane of the trunk, a plug installed in the rear part of the barrel with an axial bore made

with counterbore, bolt-mounted shutter with drummer and. trigger mechanism and placed in the barrel obturator 2.

The disadvantages of this device are in the complexity of operation, the lack of stabilization of the process of throwing when using projectiles in the form of destructible

shells filled with a viscous mixture. The purpose of the invention is to improve the operating conditions.

This goal is achieved by the fact that a device for throwing, predominantly viscous mixtures enclosed in a crushable shell, includes a support fixed on it with the possibility of turning in a vertical plane a trunk mounted in the rear part of the barrel a plug with an axial bore made with a counterbore mounted on the shutter with a hammer and a trigger and a shutter placed in the barrel,

equipped with ejector sleeve, raskischenny in the radial groove, made on the outer surface of the plug. In this case, the ejector is made

in the form of a two-armed arm, hinged

fixed in the radial groove of the stub, one shoulder of which is made in the form of a plug, which is included in the counterbore of the holes in the plug and interacts with the restrictive shoulder made on it, and the second with the end protruding from the radial groove, having the ability to interact with the bolt.

In addition, to stabilize the throwing process, the obturator is made with an annular groove in the peripheral part of the end, which forms a cavity with the plug, and the plug is equipped with a fitting that is integrated on its outer side with a check valve that communicates with the specified cavity.

The device comprises a barrel 1, a ball mounted in racks 2 of a turntable 3 mounted on a movable platform 4 (shown in Fig. 1 partially). One of the pivots of the hinge of the barrel 1 serves as the shaft of the gear wheel 5, the output shaft of which is a double hinge of the Gun with an intermediate spline telescopic shaft b connected with a flywheel 8 installed in the trunk bracket 7. The upper part of the front end of the barrel 1 is cut off with a slope and left The lower part serves as a bed and a guide for loading into the bore of a viscous concrete mix packaged in a sacrificial shell. The rear part of the bore 1 is closed by a plug 9, along the axis of which a hole 10 (chamber) is made to install the squib. On the plug 9, on the outside on the axis 11, a pivoting bolt 12 with a handle 13 is hinged. The shutter 12. is made in the form of a plate into which the sleeve 14 is pressed on one side. At the end. This sleeve, protruding from the outside of the shutter 12, is mounted on the thread and fixed the housing 15, the striker 16, which is briskly mounted in the sleeve 14 and in the housing 15 on the spring (shown conventionally with axial lines). The end of the striker 16 extends beyond the limits of the housing 15 provided with a lid 17 in the form of a flange with a nozzle. At the end of the striker 16, a sleeve 18 is fixed with a lever 19 for cocking the striker. In the nozzle of the lid 17, a slot is made along the entire length of the lever 19 forming for free movement.

when lowering the firing pin 16 and notches to position the lever and keep the firing pin in the cocked position (when turning the lever 90 ° in either direction after the firing pin is raised). To simplify the descent of the striker 16, a lever 21 mounted on the spring 20 is pivotally mounted on the flange of the lid 17 (the trigger mechanism enters the transverse slot of the nozzle of the lid 17 and into the groove on the tail section of the stern of the striker 16. To set the bolt 12 to a position corresponding to locking the hole To install the squib, the plug 9 is provided with a stop 22. To lock the bolt 12 in this position, a hole is drilled into the bolt plate, into which the end of the lock 23, fitted with a lever 24 and installed in the opening, is slanting and an emphasis 22 on a spring 25 fixed in a groove of an emphasis 22 by a pin 26. To remove an ejected sleeve or; an unused squib, in the radial groove of the plug 9, an ejector lever 27 is installed, pivotally fixed by an axis 28 in the insert 29 in the form of a key recessed into an adjacent radial groove of the groove. The end of the long arm of the lever 27 is designed in the form of forks 30, which includes a hole for mounting the squib from the outer end of the plug 9 and interacting with the base of the squib of the squib. The crustal shoulder 31 of the lever 27 protrudes from the radial groove of the plug 9. To limit the rotation of the bolt 12 when recharging the stopper 9, an emphasis 32 is made. For convenience of operation and rotation of the barrel 1 around the vertical axis of the swivel bearing 3, the bracket 9 with handles 34 is fixed on the stopper 9 Installation of the obturator 35 in the form of a disk made of soft textolite material, wood, plastic, etc. is provided in the bore of barrel 1. The obturator 35 can be made with a groove on the peripheral part of one end or, as shown in FIG. 3 steps (option for making the mentioned groove). In the cavity of the bore 1 formed by the groove in bbturator 35, can be bred 36, made for example in the plug 9, at the entrance to which the outside inlet valve 37 is installed.

Taking into account the wear of the hole 10 with frequent installation and removal of the squib, it is made in the sleeve 38 installed in the plug 9. For repeated use of the shutter 35, the latter is fixed on a cable (not shown) fixed by the other end on the stop of the device.

The device works as follows.

A obturator 35 is introduced into the bore 1. Then, a shell (snaps), packed with a section corresponding to the bore cross section, is placed on the front part of the barrel.

After that, rotation of the flywheel 8 through Hooke’s double hinge with intermediate splined telescopic shaft 6 and the worm gear reducer 5 of the turn removes the worm wheel on the trunnion hinge pin, which is set to the required angle relative to the vertical surface to be machined. Subsequently, the lock of the turntable 3 is released and, using handles 34, the barrel rotates around the vertical axis in the direction of the mixture throwing. If necessary, the platform 4 is moved. To install the squib, the lever 19 is retracted, rotated 90 ° and installed in the notch on the lid port 17. At this, the hammer 16 is shifted to the side, compressing the spring. Under the action of the spring 20, the end of the lever 21 enters the groove on the tail end of the impactor rod. The lever 24 of the latch 23 is pulled out and the handle 13 of the shutter 12 is sharply turned to contact with the stop 32. At the same time, the slide of the shutter 12 at the end of the stroke sinks the short arm 31 of the lever 27 and rotates the lever 27 around the axis 28. In the case of sleeve 30 fork when turning the lever 27 throws this sleeve.

The shutter 12 is withdrawn to its original position, after which the squib is inserted into the axial hole 10 in the plug 9 in (chamber) and the knob 13 of the shutter 12 starts the cartridge chamber. In this case, the gate plate 12 will first drown the lock 23, remove the spring 25, and then reach the stop 22, the hole in it will align with the lock 23, and under the action of the spring 25 the lock will enter the hole in the gate plate, fixing its position.

For the production of the protrusion, the lever 19 is pulled down, turned down until it coincides with the slot in the nozzle of the cover 17, and is gently released until the end of the groove on the tail end of the hammer rod 16 is in the lever .21.

When the second end of the lever is pressed, it rotates around the axis of the hinge attachment, compressing the spring 20. The end of the lever 21 that enters the groove of the impactor shaft 16 rotates and releases the impactor 16, which, due to the action of its own spring, strikes the cap of the squib.

The gases produced by the explosion of the igniter charge, act through the obturator 35 on the

the barrel 1 is wrapped by a concrete viscous mixture, throwing it at high speed out of the barrel in the direction of the surface to be treated. In this case, the shell, when ejected from the barrel, is destroyed and the air resistance is thrown to the side, freeing the concrete and viscous mixture, which reaches the surface and is applied to it.

Adjustment of the power of throwing can be provided not only by changing the charge of the squib, but also additionally by injecting bore 1 into the iocTb of the barrel 1 formed by bore at one end of the obturator 35 of the explosive gaseous substance through the built-in plug 9 check valve 37.

Due to the presence in the ejection device of the used cartridges of the squibs, as well as the possibility of adjusting the power of the methane-viscous mixtures enclosed in a ruptured shell, by introducing gaseous explosives into the cavity of the borehole of the barrel,

It is used to stabilize the process of throwing viscous concrete mixes when processing various surfaces.
