Safety barrier stand

Abstract

This utility model relates to the design of devices that block or restrict vehicle movement, particularly for the creation of modular and individual barriers for parking spaces, industrial plants, cargo transportation and handling facilities, loading and unloading areas, production lines, and process equipment. The technical challenge addressed by this solution is to ensure, on the one hand, elastic deflection of the post under light loads, and, on the other hand, separation from the base under heavy loads (deflection at a significant angle), with the possibility of subsequent reinstallation. To achieve this, the base comprises a central insert made of structural material, permanently installed within the base. Its central portion, for accommodating the signal post, is shaped like an inverted truncated cone with a groove with smoothed edges.The signal post is circular in cross-section, with a conical section and protrusion at the bottom that replicate the shape of the inner portion of the central insert, forming a locking mechanism during assembly. The signal post, at least in the area where it contacts the central insert, is hollow and has vertical through-grooves designed to reduce the insert's diameter under compressive forces during installation and removal.

Description

[0001] This utility model relates to the design of devices that block or restrict vehicle movement, in particular for the creation of modular and individual fencing for parking spaces, industrial facilities, cargo transportation and handling complexes, loading and unloading areas, production lines, and process equipment. It can be used as a signal barrier to separate traffic flows, as well as traffic and pedestrian flows.

[0002] From the Russian Federation patent No. 160269, a road signal post is known, adopted as a prototype, containing a base with a signal post fixed in it, the base is made of flexible PVC with the possibility of fastening with anchor bolts in the road surface, and the signal post is made in the form of a plate with an arcuate shape in plan from a material with low residual deformation and on its surface there are stiffening ribs in the form of longitudinal protrusions.

[0003] The general essential features of the proposed solution, which coincide with the essential features of the prototype, are the following: a safety barrier post containing a base with a signal post fixed in it, the base is made of an elastic material with the possibility of fastening with anchor bolts in the road surface.

[0004] During operation, this signal post, if there is no additional fastening at the base, will be easily pulled out even by hand, or, if there is any fastening to the base, it will be pulled out with the fastener.

[0005] The technical problem that this technical solution is aimed at solving is to ensure, on the one hand, elastic deflection of the rack under light loads, and on the other hand, in the case of high loads (deflection at a significant angle), separation from the base, with the possibility of subsequent reverse installation.

[0006] The stated technical problem is solved in that the safety barrier post, comprising a base with a signal post fixed therein, the base is made of an elastic material with the possibility of fastening with anchor bolts in the road surface, in contrast to the prototype, the base contains a central insert made of a structural material, installed in the base permanently, its central part for placing the signal post has the shape of an inverted truncated cone, having a recess with smoothed edges; the signal post is made of a circular cross-section, with a conical part and a protrusion at the bottom, repeating the shape of the inner part of the central insert, forming a lock during assembly; the signal post, at least in the contact zone with the central insert, is made hollow and has vertical through grooves made with the possibility of reducing the diameter of the insert from the compressive force during installation and dismantling and returning to its original position without destruction.

[0007] Thanks to the central insert, even with minor deformations (small tilt angles, for example, up to 15°), the signal post springs forward within the elastic base, maintaining their mutual engagement in the lock. Under greater loads (greater tilt angles), the signal post disengages from the locking mechanism of the central insert due to the conical shape, compression of the groove, and smoothed edges of the groove and protrusion. Furthermore, if the signal post is not damaged (which can occur at high speeds and / or when colliding with a vehicle), it can be reinstalled (restoring its original configuration).

[0008] This technical solution can be used, in particular, to create modular and custom fencing for parking spaces, industrial facilities, cargo transportation and handling complexes, loading and unloading areas, production lines, and process equipment. It can also be used as a signal barrier to separate traffic flows, as well as traffic and pedestrian flows. It can also be used in a modular design, with adjacent posts connected by rigid or flexible ties.

[0009] The proposed technical solution is explained in Fig. 1-7.

[0016] Fig. 7 shows a signal post that has fallen out of the central insert.

[0017] The safety barrier post shown in Fig. 1-7 comprises a base 1 made of an elastic material with a central insert 2 made of structural plastic permanently installed therein, into which a signal post 3 is installed, the base 1 is configured to be secured with anchor bolts 11 in the road surface 4, the central insert 2 has the shape of an inverted truncated cone 5 having a recess 6 with smoothed edges. The signal post 3 is made of a circular cross-section, with a conical part 7 at the bottom and a projection 8, repeating the shape of the inner part of the central insert 2 (the inverted truncated cone 5 and the recess 6), forming a lock during assembly. The signal post 3, at least in the area of ​​contact with the central insert 2, is made hollow and has vertical through grooves 9 configured to be compressed during installation and dismantling.

[0018] The central insert is designed to secure the pipe. Its inner surface is shaped like a truncated cone 5, with a recess 6 at the bottom that forms a "lock" for securing the pipe. On the outer side of the central insert 2, there are ring-shaped hooks 10 that act to counteract the pull-out force. The central insert of the proposed form can be made from a structural composite material (for example, a thermoplastic: polyamide, polyphenylene sulfide, polyarylene ketones, polyarylene sulfones, or a thermosetting: polydicyclopentadiene, polyester, polyepoxide, filled with reinforcing fibers - glass, carbon, basalt - with a fiber content of 0% to 60% depending on the type of polymer matrix used and the type of fiber), or from a corrosion-resistant metal alloy by various methods, casting, turning of the workpiece, a combination, for example, obtained by casting from a rigid structural thermoplastic.The base of the collar is elastic, for example, made of rubber or flexible polyurethane, which ensures self-alignment at small angles of deviation of the signal post 3 from the vertical under external influence. The central insert 2 is typically molded into the base blank, which, after vulcanization, forms a permanent connection. The material of the signal post 3 can be thermoplastic, such as polyolefin, polyvinyl chloride, polyalkylene terephthalate, or polyurethane, formed by melt extrusion of the polymer or by hot winding of a semi-finished tape based on thermoplastic and continuous reinforcing fiber. Priority is given to the use of the most readily available polymer composites, predominantly polyethylene or polypropylene. The required shape of the pipe in the contact zone can be achieved by blow molding, machining, or a sequential application of these methods.

[0019] In the operating position, signal post 3 is inserted into central insert 2 of base 1 until it clicks into place. Locking is ensured by the shape of post 3's lower tube, which replicates the shape of central insert 2 in the contact area: a cone 7 and a thickening 8 (the "lock"). Post 3's tube also has grooves 9 (notches) in the contact area, facilitating separation of the structure when struck by a vehicle. Grooves 9 (in this case, two, but there may be more) are located symmetrically relative to the longitudinal axis of post 3's tube.

[0020] The safety barrier post can be installed at the installation site either as an assembly, or first the base 1 with the central insert 2, and then the signal post 3 is installed until it clicks (implementing the locking fastening). The configuration of the signal post 3, the base 1, the central insert 2 and the materials used together make the structure vertically fixed in a stationary position and detachable and deformable when the signal post 3 is subjected to an impact.

[0021] The proposed design operates as follows. During a slow approach and a deflection angle of approximately 15°, signal post 3 and central insert 2 tilt due to the elasticity of base 1 (Fig. 4). After departure, post 3 returns to its original position.

[0022] During a more intense collision (further) at a low speed of up to 5 km / h, signal post 3 first loses contact with the inner surface of the central insert 2 due to the narrowing of groove 9 (Fig. 5), then the lock opens and post 3 comes out of insert 2 (Fig. 6), and then falls out of it (Fig. 7). If after the collision base 1, insert 2, and post 3 are not damaged, then post 3 can be installed in place.
