LT6676B - High strength car insert with a high adhesion tape and amortization mounting system - Google Patents

Abstract

The car insert is designed for transporting dry, finely divided cargoes with a high bulk density, such as alumina and cement, and has fastening elements to rigid fixed parts of the vehicle, in particular, a gondola car, as well as four charging valves located in the upper part, which are distinguished by the fact that the car insert is made in the form of a parallelepiped, and the structure of the insert is additionally introduced a shock-absorbing system of the installation, and the insert consists of two layers—internal and external ones, which are interconnected with a tape of high adhesion, which helps to eliminate sagging, exfoliation, and airlocking of the interlayer space.

Description

The wagon liner is intended for the transport of dry, fine-dispersed cargoes with a high rash density, such as alumina and cement.

Known container for bulk cargo (Russian Federation Utility Model Patent No. 90751, published January 20, 2010), which has a flexible liner made of woven material for bulk transportation in railway semi-wagons.

Also known is a bulk container (Russian Federation utility model patent 101420, issued January 20, 2011), which is made in the form of a vehicle's internal volume and has floor hatches fitted to rigid fixed parts of the vehicle, namely a semi-wagon , elements and at least one charging hose at the top. According to this known device, the container has an inflatable pneumatic cushion constructed so as to be positioned along the vehicle, i.e.. along the length of the semi-wagon, between the hatches on the floor. The hooks are laid around the entire circumference of the liner.

The use of this liner is unacceptable for goods with a high rash density due to the dimensions and shapes of the wagon liner.

The dimensions of the liner replicate the inside shape of the wagon and its shape is an inverted trapezoid or prism with a width at the upper base greater than the width at the lower base. The insertion of the liner into the wagon results in wrinkles which "steal" the main dimensions of the liner, especially its length of 13 meters. Thus, the size of the wagon liner should not repeat the internal dimensions of the wagon, but should be larger, taking into account the error due to the wrinkles that occur during installation. Thus, for a wagon length of 12900 mm, the wagon liner should be at least 13100 mm.

In the form of an inverted trapezoid or prism, where the upper base is wider than the lower base, it also has two weaknesses for loads with high rash density.

For example, the loading of the overlay on the sidewalls during loading causes wrinkles on the sidewalls to pull the wagon liner down and tear it out of the mounting straps during loading, and the upper base to collapse and form two large recesses when loading the liner in bad weather (rain or snow) these depressions receive rainfall, which also pulls the wagon liner down. And when loaded, there is excess material that is inflatable during transportation and presents a risk of overhead power lines that can be hooked.

Known container for bulk cargo (Russian Federation Utility Model Patent No. 90751, published January 20, 2010), having a flexible liner for bulk freight rail wagons made of a woven material having dimensions corresponding to the inside dimensions of a wagon, the liner completely enclosing surface and having an upper wall, the insert members being interconnected by a sewing method along the entire length of each edge of the insert, and the upper wall of the insert having at least one loading hose.

According to its technical essence, purpose and achievable result, the closest invention to the claimed invention is a container for bulk cargo (utility model patent No. 101420 of the Russian Federation, published 20-01-2011), which is manufactured in the form of a vehicle internal volume and fitted with hatches rigid parts of the vehicle, namely the semi-wagon, and at least one loading hose at the top. According to this known device, the container has an inflatable pneumatic cushion constructed so as to extend along the vehicle, i.e. along the semi-wagon, between the hatches on the floor. The lugs are laid around the entire circumference of the liner.

This well-known wagon liner has hammocks with mounting straps that attach the liner to the frame during loading, but in reality and in practice, they may be missing or pull the luvern out of the material. This causes the liner to fall on the wagon bottom, thus interfering with the loading process. The drawbacks are due to the fact that one of the folds formed during installation was very large, and after the high-density load has been loaded, it cannot straighten under this load and pulls the wagon liner down.

The object of the present invention is to eliminate the possibility of the interlayer space to be bent, layered and filled with air.

This is accomplished by the fact that the wagon liner is made in the form of an interior volume of a vehicle with floor hatches and is fitted with rigid fixed parts of the vehicle, namely a semi-wagon, and at least one loading valve at the top. According to the present invention, the wagon insert is made in the form of a parallelepiped, the parts of which, in particular the outer and inner layers of the liner, are further joined by double-sided high adhesive tape, and the insert component additionally introduces a shock mounting elements that are pulled through loungers or eyelets and the liner dimensions are larger than the inside dimensions of the wagon.

The reliability of the liner for the transport of loads with high rash densities is enhanced by the addition of a cushioning mounting system, the wagon liner is made in the form of a parallelepiped, flexible mounting members on the upper base perimeter of the liner that are pulled through luvers or eyelets. the dimensions are greater than the inside dimensions of the wagon. Thus, the bulk liner is not vulnerable to bulk loading as the cargo is distributed in folds that are smoothed by the extra volume.

If the liner folds on one side and pulls it down, the mounting rubber-shock absorber will also stretch and at the same time keep the liner suspended.

Extra reliability is provided to the liner when the liner is made of two layers. The braided laminate layer protects the load from the outside while the entire welded polyethylene inner layer provides extra tightness. The use of a high-adhesion tape, which connects the inner and outer layers to each other, results in a tight fit of one layer to another. Depending on the length and width of the wagon, the liner shall be 100-300 mm larger than the inside dimension of the wagon, which causes an error in the formation of wrinkles.

BRIEF DESCRIPTION OF THE DRAWINGS The present invention is illustrated by drawings showing a general view of the insert.

Figure 1 shows the wagon insert from above; Figure 2 is a side view of a wagon insert; Figure 3 shows the wagon insert from below.

The wagon insert with damping mounting system is a wagon insert in the form of a smooth wall 1 with four loading valves 2 and fitted with mounting rings 3 on the perimeter of the top base of the insert, which are larger than the inside dimensions of the wagon. The liner consists of two layers, an outer layer and an inner layer bonded together by a high-adhesive adhesive tape 4. The outer layer is made, for example, of a braided laminate material which protects the load from damage and the inner layer is made of all welded polyethylene.

the liner is used as follows. The straps at the lower perimeter of the base are fixed to the rigid structure of the wagon by lashings to the existing wagon eyelets. Thus, the liner is ready for loading. Loading is via the loading hoses (see Figure 1-3).

After loading the liner, the loading hoses are then closed and then cut and the liner can be transported to its destination with the load.

The loaded semi-wagon is unloaded in a known manner through the lower hatches of the semi-wagon, cutting the liner material with a sharp object and releasing the load through the lower hatches.

Thus, the present invention achieves the object of eliminating the possibility of the interlayer space to be bent, laminated and filled with air.
