Description

one

BACKGROUND OF THE INVENTION The invention relates to crusts with opening legs, which are immersed in loose soils by firing. Such measles can be used, for example, to loosen various floating objects.

Known measles with drop-down legs is known, which contains a spindle, on which legs with ribs mounted on a common axis, are hinged and mounted on a common axis, bracings to hold the legs in an open position, and bridle fixed on the spindle. Shot bark of such a co-adjustment, especially with a cylindrical spindle and flat paws, experience with their immersion a great resistance of the soil. With the legs of a curvilinear outline in the plan, difficulties arise in the question of ensuring the reliability of opening the legs during the removal of the core.

To reduce the resistance of the soil when the core of the spindle is inserted into it, it is made with a cross-shaped cross section and contains transverse and longitudinal ribs located between the edges of the legs and equipped with streamlined collars with fixed straps passing through conical collars fixed on the spindle and mounting plates and having at the ends of the tapered couplings, fixed in the tapered yoke.

In addition, to protect the hinged joint of the legs with the spindle from overloads during acceleration of the core, the axis on which the legs of the core are placed can be movably mounted in

an oblong hole made in the body of the spindle, equipped with projections interacting with the edges of the legs.

In order to facilitate the opening of the paws, when removing the core on the planes of the paws,

Pointed plates fixed at an angle to the planes of the feet, with the Bridel located in a plane perpendicular to the plane of rotation of the feet of the cor. The design of the core is designed taking into account

that the gun for firing the bark has an element (rod) pushed out when fired, to which measles is attached. FIG. 1 shows a general view of the core before immersion, with the dotted line showing the paw in the open (working) position; in fig. 2 is a section along A-A in FIG. one; in fig. 3 - measles, left view. Anchor contains cruciform spindle

section 1, on which paws with ribs 2, which sit on a common axis 3, are pivotally mounted, protrusions 4, which serve to hold the paws in the open position, and bridle 5, which is attached to the spindle and goes to the object to be fixed.

The spindle core contains a transverse and longitudinal ribs, a pointed head and a shank, which serves to connect the core with the ejected element (rod) of the gun.

Paws of the core are made in the form of a heel, their planes reinforced with two or more ribs. The ribs of the paws are rammed, the axes on axis 3 are such that the longitudinal edge of the spindle is between the edges of the paws, and the edges of one paw are between the edges of the other.

Thanks to this design of the spindle and legs, compactness of the core is achieved.

The axis on which the legs of the cortex are planted is mounted on the node but in an oblong core, made in the body of the spindle, therefore the spindle and the legs can mutually move in a vertical plane by a specified amount.

The paws are equipped with streamlined clips b used to seal them, for example with the help of molten metal, of the lower ends of the straps.

The slings freely pass through the conical clips 7 fixed on the spindle of the core. The upper ends of the tailgate are provided with conical sleeves 8, with the help of which the sleeves are fixed in the conical holders of the spindle with the legs fully opened.

Bridel is located in, perpendicular to the plane of rotation of the paws, and may consist of one or more threads (in cross section) made of cables, synthetic ropes, chains and located symmetrically with respect to the plane of rotation of the paws.

In the edges of the spindle are provided in the appropriate places of the hole to secure the bridle.

In the position of the core, before the shot, the paws are closely pressed to the spindle and, together with the cable outlets, are held in a vertical position with the help of mounting plates 9 fixed to the spindle.

During acceleration of the core, at the moment of the shot, under the action of inertial forces, the paws with the axis of rotation move upwards with respect to the spindle until their ribs are pressed into the projections 10 provided on the spindle. The load from the paws is transmitted directly to the spindle, and the hinge assembly

The connection of the paws with the spindle is protected from overloads and can be facilitated. To protect the joint from impact when the core enters the ground in the nose of the spindle, there are some thickenings that serve at the same time as a support for the paws when they are open.

In order to facilitate the opening of the paws while removing the core on the carrying planes of the paws, there are pointed tip plates 11 arranged at an angle to the planes of the paws. In addition, tides 12 are provided on the spindle, which, when the spindle is moving relative to the paws upwards during extraction

core interact with paws, pushing them apart.
