Description

The invention relates to devices for securing goods on vehicle platforms, preferably for mounting wheeled and tracked vehicles on railway platforms.

A device for attaching wheeled vehicles to a vehicle is known, comprising a stretch that is adjustable along the core element and is attached to one end of the cable, the other end of which is fixed on the C-shaped grip with a chute equipped with hooks.

Due to the presence of hooks, the C-shaped element has large dimensions and it is difficult to install it in tight places on the elements of the fixed equipment, especially since to select the slack of the cable, the grip must be turned. In addition, due to the fact that the load in this device is transmitted only through one branch of the cable, it is necessary to increase the diameter of the cable, which leads to an increase in the size of the C-grip in order to ensure the admissible bending radius of the cable.

A device for securing cargo on a vehicle is known, comprising a length-adjustable stretch mounted on a core element with a traverse arm hinged on it, to the ends of which is attached a cable, an envelope rim mounted on the power elements of the cargo being fixed.

The disadvantages of this device include the need for a large stroke of adjustable stretch (lanyard). So, with a rim groove diameter of 120 mm, taking into account the cable diameter and overlapping of the cable coils, the cable length of more than 400 mm or more than 200 mm on one branch is selected for one coil. Thus, to ensure the tension of the cable, the stretching stroke must be more than 200 mm, which leads to large dimensions and stretching weight and increases the time for securing the load, which is used to rotate the lanyard to select a free wheel. Given the large amount of stretching required to secure a large cargo, most of the time spent for securing is spent on the rotation of the turnbuckle.

The purpose of the invention is to increase the ease of use

The goal is achieved by the fact that the ends of the cable are provided with stops, the sleeves with supporting end surfaces are worn with the ability to move, and at the ends of the traverse there are grooves with a width greater than the diameter of the cable but smaller than the diameters of the supporting surfaces of the sleeves.

Due to the change in the number of bushings between the cable stops and the ends of the traverse, a sample of the slack is faster and more complete than the prototype.

cable, which reduces the working stroke of the adjustable tie rod. The presence of grooves at the ends of the crosshead ensures that the cable is removed to move to the ends with stops of the required number of bushings.

0 In addition, in order to improve reliability, the shoulders are made at the ends of the sleeves, and at the ends of the socket cross-brackets and clamps for engagement with the said shoulders. Sockets and retainers keep bushings from

5 falling out during operation in case of loosening of cable tension.

Figure 1 shows the device, a general view; figure 2 - section aa in figure 1; figure 3 - section bb in figure 2.

0 A device for securing a cargo contains a stretchable (lanyard) 1 adjustable in length, one end of which is fixed to the railway platform 3 by means of the core element 2, and the second hinge5 is fastened to the cross member 4, at the ends of which the cable 6 is fixed, which bends around the shaped rim 7, mounted on the power elements of the fixed cargo 8.

The presence of shaped rim 7 in this

The device is not necessary, since the cable can also bend around the power elements of the fixed load, if they have smooth rims with a radius acceptable for the cable.

5 The ends of the cable 6 are embedded in the fixed stops 9, and the sleeves are put on the moving cable

10 with supporting end surfaces

11 and pins 12.

General dyne all sleeves 10 approximately

0 is equal to the circumference of the figured rim 7, and the number is determined taking into account ease of use and the working turn of the turnbuckle 1. At the ends 5 of the crosspiece 4, the grooves 13 are made wider than the diameter of the cable 6, but

5 is smaller than the diameter of the shoulders 12. Due to this, the cable 6, but less than the diameter of the shoulders 12. Due to this, the cable 6 freely enters the groove 13, and the shoulders 12 with supporting end surfaces 11 abut against the ends 5.

0 At the ends 5, sockets 14 are made, corresponding to the sizes of the shoulders 12. The sockets 14 are not closed from the open end of the grooves 13, which allows winding the shoulders 12 into the sockets 14 along the axes of the grooves 13. At the same time

5 due to the protrusions 15 interacting with the shoulders 12, the sleeves 10 cannot be moved along the axis of the cable 6 without removing the cable 6 from the groove 13. In addition, at the ends 5 there are holes in which clamps 16 are installed, made, for example, in the form of spring

a check that prevents the removal of the shoulders 12 from the sockets 14.

The device works as follows.

To secure the load 8 on the platform 3, the core element 2 is installed in the platform lug, and on the load-bearing element 8, the figured rim 7. The sleeves 10 are approximately equally spaced at the two ends of the cable 6, the cable is twisted around the rim 7 for 1-3 turns, depending on mutual arrangement of the core element 2 and the rim 7, providing an approximate arrangement of the ends 5 of the crosspiece 4. Pull the checks 16 and wind the cable 6 with two ends into the grooves 13, having the sleeves 10 between the stops 9 and the ends 5 in such quantities as to ensure the selection of the slack of the cable 6 with discrete Strongly equal length sleeves 10.

After that, winding the piles 12 into the sockets 14 and install the checks 16. In the holes at the ends 5, the rotation of the lanyard 1 provides the necessary tension on the cable 6.

When the platform 3 is moving, even if the tension of the cable 6 is weakened, the cable does not disengage from the cross beam 4, since the projections 15 prevent axial displacement of the fixed sleeves 10, and the checks 16 prevent the sleeves from moving in the groove direction. This increases the reliability of operation of the device.

The proposed device makes it possible to reduce the time of securing the load on the platform, increases the convenience of operation, reduces the consumption of materials of the adjustable stretch, and secures the load in conditions of constrained space,
