Description

The invention relates to collapsible devices designed for fixing operations on vehicles with the required angle of inclination of stretch marks and (or) to transfer objects for various purposes (transport containers, boxes and other products). In particular, when performing these operations (securing, loading / unloading), hook and loop, known as hook and eye bolt according to the reference book of a mechanical designer, are used as load-gripping elements of the device. Anuryev, Volume 1, 8th edition revised and enlarged, Mashinostroenie publishing house, Moscow, 2001, p. 9, 823, 834. An eyebolt is a ring connected to a threaded rod screwed into an object. The hook is a hook with a threaded rod screwed into the object. However, the patent search did not reveal objects that satisfy the claimed invention, containing two features in one.

The aim of the invention is the expansion of operational capabilities.

The goal is achieved due to the fact that the rigging and mooring unit contains a rod with coaxially mounted on it with the possibility of rotation of the sleeve and bracket; the design of the bracket provides for the implementation of the mounting elements of the axis with load-gripping elements located on it with the possibility of independent rotation; the rod and axis are mutually perpendicular; axis fixing elements are holes in the protrusions of the bracket; the rod and sleeve are made of dissimilar materials, for example, rolled steel and bronze, respectively; the device is collapsible; load gripping elements are hook and loop.

The invention is illustrated by drawings, which depict:

in FIG. 1 - structural design of the rigging and mooring unit and its main elements (initial position, main view);

in FIG. 2 - structural design of the rigging and mooring unit and its main elements (initial position, 3d view);

in FIG. 3 - rigging and mooring unit in working position when used for the intended purpose of the hook;

in FIG. 4 - rigging and mooring unit in the working position when used for the intended purpose of the loop.

The lifting and mooring unit consists of seven elements - a rod 1, a sleeve 2, an arm 3, a cotter pin 4, an axis 5, a loop 6 and a hook 7.

The rod 1 is the structural bearing during rigging and mooring and is fixed on the object 8, subjected to fixing on the vehicle and (or) transfer. The rod 1 is made in the form of a bar with a circular cross section, which does not limit other design. A sleeve 2 is coaxially mounted on the rod 1 with a bracket 3 fixed on it. To prevent jamming and jamming when the sleeve 2 rotates around the axis of the rod 1, the diameter of the hole in the sleeve is structurally larger than the diameter of the rod 1 by (0.5 ... 2.0) mm based on weight and size characteristics of these nodes. The bracket 3 is designed to provide two degrees of freedom of the structure as a whole due to the perpendicular arrangement of two geometric axes of rotation, one of which passes through the axis of symmetry of the rod 1 (see Fig. 2), and the other through axis 5. The angle of rotation of the bracket 3 relative to the axis of symmetry the rod 1 can be limited only by the design of the object 8. In order to avoid diffusion during operation, it is necessary to make the rod 1 and the sleeve 2 from dissimilar materials, it is preferable to make the rod 1 of rolled steel and a sleeve 2 made of bronze.

The load-gripping elements 6, 7, preferably steel, are attached to the bracket 3 on one geometric axis, namely the loop 6 and hook 7, for example, by means of a cotter pin 4 and axis 5, due to the fact that in the design of the bracket 3 there are protrusions in the form of ears with holes. The holes in the protrusions of the bracket 3, loop 6 and hook 7 are made with a diameter that ensures the axis 5 is in contact. The cotter pin 4 fixes the axis 5 in the structure in order to prevent its spontaneous loss from the device during operation, which does not limit the use of other locking elements in this structure. To avoid jamming and jamming during rotation of the loop 6 and hook 7 relative to the axis 5, the diameter of the holes in the bracket 3, loop 6 and hook 7 is structurally performed larger than the diameter of the axis 5 by (0.5 ... 1.5) mm based on the weight and size characteristics of these nodes. The rotation angle of the loop 6 and the hook 7 relative to the axis passing through the points of their attachment can be limited only by the design of the object 8 and the bracket 3. The loop 6 and the hook 7 are fixed in the device with the possibility of their independent rotation relative to the axis 5 on which they are fixed. When carrying out rigging and mooring operations, both loop 6 and hook 7 can equally be used.

The number of rigging and mooring units is selected depending on the desired task, design and weight of the object 8.

The considered rigging and mooring unit operates as follows.

Depending on the required task (moving or securing the object on the vehicle), as well as the counterparts of lifting devices or extensions (loop, hook or other), loop 6 or hook 7 is used. The counterpart of the lifting device or extension is attached to loop 6 or hook 7 . Then the immediate task is carried out, namely, the transfer of the object or its fastening on the vehicle by means of stretch marks with the provision of their required angle of inclination due to the possibility of rotation of the rigging and mooring unit relative to its mutually perpendicular geometric axes of rotation, which eliminates possible deformation of the connected objects when they are fastened. For a clearer understanding of the operation of the device as a whole in FIG. 3 shows the rigging and mooring unit with the hook 7 used for its intended purpose under the working load P, and in FIG. 4 shows a rigging and mooring unit with a loop 6 used for its intended purpose under a working load R.

The invention relates to collapsible devices designed for fixing operations on vehicles with the required angle of inclination of stretch marks and (or) to transfer objects for various purposes (transport containers, boxes and other products).

The technical result of the invention is versatility due to the use of various load-gripping elements in its design, manufacturability due to a collapsible design, elimination of possible deformations of connected objects when bonding due to the location and providing the required angle of inclination of the load-gripping elements by the possibility of rotation of the lifting and mooring unit relative to its perpendicular geometric axes.

This design of the rigging and mooring unit is implemented in transport containers intended for transportation of space technology products. In order to carry out rigging and mooring operations with the container, which is structurally made in the form of a rectangular parallelepiped, four rigging and mooring units are provided in its design located at the corners of the containers at an equidistant distance relative to the geometric center of the container. The rotation angle of the hinges and (or) hooks relative to any of the two mutually perpendicular planes is at least 180 ° and is limited only by the design of the container.

The proposed technical solution is an effective rigging and mooring unit, allowing its use in various rigging and mooring structures, as well as simple and reliable in operation.
