Description

The locking device for collapsible pavements relates to the field of road construction and can be used for the construction of temporary roads with transitional and lower types of coatings, which include collapsible pavings, and can be used in various industries. For example, the instruction for the construction of temporary roads for pipeline construction in difficult conditions (VSN 2-105-78), Minneftegazstroy, M., 1978, provides for the expediency of constructing temporary roads on flooded and wetlands. In accordance with this, the scope of application of the claimed technical solution is the construction of temporary roads, as well as the construction of temporary sites in areas with weak soil, waterlogged and swampy areas, to ensure the passage and parking of wheeled and tracked vehicles weighing up to 60 tons.

Known castle connection plates of collapsible pavements, the end faces of which have locking elements for interaction with mating locking elements of adjacent plates. At the same time, the locking elements have clamps for connecting the plates to each other, which are made in the form of protrusions opposite to the opposite sides of the plate, one of which contains a spherical bulge along the entire length, and the other contains a spherical concavity corresponding to the diameter of the bulge (RF patent No. 121818 U1, Е01С 5/00, 11/10/2012).

The closest known device is a locking device for plates of collapsible road surfaces, containing channel-shaped fastenings to the plates facing the shelves, interconnected by means of a hinge, the axis of which is parallel to the shelves of the channel-shaped fasteners and passed through the holes of the loops fixed to the corresponding channel-shaped fasteners moreover, under the swivel is a support plate fixed to one of the channel-shaped fasteners, printing increased rigidity and strength of the locking device (RF patent No. 152598 U1, ЕС 5/00, 12/22/2014).

The proposed technical solution is a further improvement of this previously developed design of the castle device, which takes into account the possibility of reliable operation of such castle devices in a wide temperature range and in various soils with different moisture content, as well as in snow and ice conditions.

The task to which this docking device is aimed is to create a locking device that is reliable in various thermal and abrasive conditions to provide the possibility of perceiving the design operational loads for a long time with the possibility of subsequent dismantling of the paved road surface.

The technical result consists in increasing the reliability of the locking device in various thermal conditions.

This is achieved by the fact that in the locking device for collapsible road surfaces, containing the channel-shaped fastenings to the plates facing the shelves in opposite directions, interconnected by means of a hinge, the axis of which, made in the form of a finger fixed from falling out, is passed through holes located in parallel loops one channel-shaped fastening, in the gap between which there is a loop of another channel-shaped fastening, made with the bottom open and tapering up a groove having in its upper part a cylindrical surface in contact with a stop fixed under the axis in the gap between the loops. In addition, the hole for the hinge axis can be made in one of the loops located in the gap between the others, oblong in the direction of the channel-shaped fastening of the plates, or the holes for the hinge axis can be made in a pair of loops forming the gap, oblong in the direction of the channel-shaped fastening of the plates. The axis of the swivel, made in the form of a finger, can be fixed, for example, with a cotter pin or other quick-mount. And channel-shaped fastenings can be made with holes for placement of elements having a countersunk head connecting them to the plate.

The causal relationship of the features of this technical solution and the specified technical result is due to the fact that the fastening to the channel-shaped plates ensures reliable and uniform loading of the edges of the plates and the redistribution of the applied operational load on the large sections of the plate fixed between the shelves of the indicated fasteners, which makes it possible to perceive a large largest operational load. The parallel arrangement of the loops and their interconnection in the gap located under the axis of the emphasis, which covers the top formed in the loop of another channel-shaped fastening groove (slot) increases reliability due to the fact that it allows you to significantly unload the hinge assembly by redistributing (power circuit) the operating load on the stop while the movable hinge assembly practically shuts down from work, which positively affects its reliability, especially in an abrasive environment, and the durability of the entire structure ruction. The presence of a groove (slot) that is open from the bottom and tapers upwards allows to increase reliability by displacing the abrasive medium from such a gap.

In FIG. 1 shows a General view of the locking device for collapsible road upgraded coatings;

In FIG. 2 is a view of a channel-shaped fastener having double hinges and a stop fixed between them;

In FIG. 3 is a view of a channel-shaped fastener with a loop having a groove of a tapering upward cross-section.

The locking device for collapsible pavement contains channel-shaped fastenings 1 and 2, which are facing shelves 3, 4 and 5, 6 in opposite directions to the plates (not shown conditionally). Loops 8 and 9 (ears and cheeks) are connected by means of a weld seam 10 to the corresponding channel-shaped fasteners 1 or 2. Fastened on one of the channel-shaped fasteners, the loops 8 are located in parallel with the gap in which the loop 9 of the other channel-shaped fastener is located. A stop 11 of a cylindrical shape is located in the gap between the loops 8 under the axis 7. The loop 9 on the lower side is made with a groove tapering (in cross section) up to a radius “R” under the stop 11, the width “a” of which exceeds the diameter of the stop 11. Moreover, the cylindrical or a quasi-cylindrical surface made with a radius of "R" rests on the stop 11. The axis 7 of the swivel is made in the form of a finger and is fixed by means of fixation, for example, a cotter pin. It is advisable to arrange the hinges forming the hinge pairwise symmetrically with respect to the transverse axis of the docking device to form a pair of hinges. On the channel-shaped fastener 3, plates 13 are welded (serving as shown in Fig. 1) to fix the chain of the axis 7. Channel-shaped fasteners are made with holes 12 uniformly distributed along the length of the shelf to connect them to the corresponding plate. The hole for the hinge axis can be made in one (9) or in a pair (8) of mating hinge loops elongated in the direction of the plates, which, in addition to reducing dynamic loads in the joint, can compensate for thermal deformations of the paved road surface, ensuring its reliable operation at various temperature conditions, and significantly reduce abrasive wear of the joint.

The locking device provides reliable bonding of the plates to each other, forming a roadway (platform) of the required standard size. In the manufacture of the locking device, materials and protective coatings are used that provide operating conditions (climatic factors of the external environment, type of underlying surface, planned loads, etc.).

Design features and special characteristics of the materials used are reflected in the following results:

- the design is collapsible, reusable;

- the ability to adapt to specific operating conditions determined by climatic factors of the environment, planned loads, etc. by varying the type, size and coating material;

- the design provides semi-rigid fastening of the coatings with a small angle of deviation of the coatings relative to each other, which ensures the work of the adhesion of coatings to work as a whole;

- the presence of increased gaps in the loops (ear and cheeks) ensures the operation of the coatings under conditions of resizing as a result of heating and cooling;

- simplicity of design provides assembly and disassembly of coatings without tools in extreme conditions (weak soils, low temperatures, bad weather conditions).

The use of a locking device will allow for quick assembly and disassembly of coatings in any environmental conditions, joining of coatings without the use of tools, providing thermal clearances, the ability to assemble disassembly in extreme conditions, which will lead to a reduction in material and technical resources and labor costs for road construction work when installing and disassembling, loading / unloading in comparison with the use of known constructions of collapsible coatings.
