FR2723892A1 - Fixing for chains for vehicles on transporter - Google Patents

Abstract

The system of chains (1) for securing the wheels is arranged in a circular and radial manner on the tyres and is fitted with an element (2) for drawing in and shortening. It is also fitted with transverse links (3). At each end of the wheel securing section are suspension links (4,5) to which are attached the suspension chains (6,7). The suspension chains are fitted to the suspension links by fixing links (8). The suspension chains then pass through the intermediate link (9), which also carries an attachment hook (10), and then return through the suspension links and are attached to the transporter chassis by secondary hooks (12) on the other end of the chains. The hooks are attached to perforations in the loading track (11).

Description

The invention relates to a device ensuring the safety of vehicles on automobile transporters and / or trailers, the construction and equipment of which allow safe transport. This safety device consists of continuous lashing means arranged on the tires in a circular manner, at the left and right ends of which a second and third lashing means are fixed respectively by means of fixing elements. These securing means are attached on each side of the tire to the perforated sheets of automobile transporters and / or trailers, so that there are two vertical ropes and a rope with an angle of 30 on the respective side of the tires. wheels. The securing means are tensioned with clamping elements and thus replace the wheel chocking device.

The state of the art is described in guidelines 2700 - VDI (Verein Deutscher Ingenieure), page 28, point 3.6 and is supplemented by specific loading instructions given by the car manufacturers. One of the ways prescribed by the manufacturers to ensure safety provides for a radial arrangement of three-point straps in conjunction with a wedging device arranged to the left and right in front of the tires.

One of the major drawbacks is that the various automobile constructions and the reduced spaces between the vehicles placed one behind the other on the conveyors cause torsion and bias tightening of the lashing straps at indefinite angles, relative to the longitudinal sides of the vehicles . The stresses to which the straps are then subjected, cause premature wear and rupture of the threads of the strap, which we have tried to limit by the use of movable hooks, but which we are unable to avoid. A second drawback at the level of the wheel chocking device is due to the fact that it is relatively rare for the fixed spacing between the holes and the variable dimensions of the tires to allow direct blocking.

The invention consists of a safety device which overcomes the aforementioned drawbacks and does not use the wheel chock device.

The solution is given by a device ensuring vehicle safety on automobile transporters or trailers, characterized in that lashing means (1) are arranged in a circular and radial manner, are provided with shortening elements ( 2) and transverse links (3) and receive the suspension links (4/5) at their left and right ends thus obtained, through which pass the lashing means (6/7) which is fixed on the one hand to the suspension link (4/5) by the fixing element (8) and on the other hand to the perforated sheet forming the rolling track by the suspension link (9) and the hook (10), and which returns to the suspension links (4/5), in order to attach the hooks (12) to the runway at an angle of approximately 30 and to replace the clamping device by means of the clamping element (13) of the securing means (7).

The invention gives the possibility of adapting the securing means (1) to the dimensions of the tires of the types of vehicles by means of a shortening element (2). The securing means (1) is provided with transverse links (3), in order to prevent it from sliding on the sidewalls of the tires and damaging the latter. The transverse connections (3) are equipped with intermediate metallic or non-metallic layers (14) and are surrounded by a strap (15), in the eyelets (16) from which pass the strings of the lashing means (1), so to prevent these strings from coming together during tightening. The transverse connections (3) can also be entirely made of metallic or non-metallic materials.

An advantageous design of the invention is obtained which takes particular account of the radius of deflection of the securing means (6/7), if the suspension links (4/5/10) are replaced by shackles (17) whose axes (18) are provided with deflection pulleys (19) made of metallic or non-metallic materials.

The perforated sheet (11) forming the runway is provided with oblong holes arranged horizontally (20) and vertically (21).

Another possibility is the additional arrangement of securing means (6/7) and clamping elements (13) if necessary.

An exemplary embodiment is illustrated in Figures 1-5 and is detailed below.

Figure 1 shows an overall drawing of the device.

Figure 2 shows the securing means (1) and the guide of the securing means (7) using the clamping element (13).

Figure 3 illustrates in detail the cross links.

Figure 4 shows half of the rolling track in perforated sheet.

FIG. 5 represents an alternative consisting in replacing the suspension links (4, 5, 9) by shackles (17) whose axes (18) are provided with deflection pulleys (19).

Figure 1 is an overall drawing of the device which illustrates the guiding of the securing means (6/7) represented by a chaining system. The lashing means (1) arranged in a circular and radial manner on the tires of the vehicle to be secured shows the arrangement at its ends of the suspension links (4/5) to which are fixed by the fastening elements (8) the means of securing (7) and the clamping element (13) to the left of the wheel and the securing means (6) to the right of the wheel.

Figure 2 is an extract that clarifies the situation.

The securing means (1) arranged in a circular and radial manner and attached to the shortening element (2) and to the transverse links (3) shows the ends which are thus formed and which receive the suspension link (5). The lashing means (7) is fixed to the suspension link (5) by the fixing element (8) and undergoes a deflection in the suspension link (9) which is attached to the runway (11) by . the hook (10). In the link (5) the securing means (7) is hooked to the runway (11) via the hook (12) at an angle of about 30 and tensioned with the aid of the element clamp (13). The circumference of the securing means (1) can be adapted to the dimensions of the tires of the types of vehicle by means of the shortening element (2).

FIG. 3 represents the structure of the transverse links (3). The intermediate layers (14) made of metallic or non-metallic materials and surrounded by the strap (15) make it possible to prevent the lashing means (1) from sliding on the sidewalls of the tires when the device is tightened and that the strings passing through the eyelets (16) do not approach. The transverse connections (3) preferably consist of a riveted assembly and can also be entirely made from metallic or non-metallic materials.

FIG. 4 represents the runway made of perforated sheet metal (11) provided with oblong horizontal (20) and vertical (21) holes, in which the hooks (10/12) are attached.

FIG. 5 represents an alternative which consists in replacing the suspension links (4/5/9) by shackles (17) whose axes (18) are equipped with deflection pulleys made of metallic or non-metallic materials. Thus, the deflection radii of the securing means are more advantageous. For this purpose, the fixing element (8) by means of lashing (1) or to the shackle (17) is necessary.
