Description

The invention relates to containers for transporting long goods with the possibility of stacking during storage, mainly for lumber, as well as a set of manor houses.

A well-known container for packaging long goods (by AS No. 370153, IPC B 65 J 1/02 of 03/29/1971, publ. 02/15/1973, BI No. 11), containing two rigid rectangular clamps, each of which is equipped cantilevered end wall, made in the form of a bracket, pivotally mounted on the inner side of the opposing clamp rods.

The disadvantages of this device include insufficient protection against mechanical damage not only to the ends, but also to the entire load, the ability to transport only packets of the same size. The device is not weatherproof.

The closest in technical essence to the proposed device is the design of the container for packages of long loads (by AS No. 789338, B 65 D 90/02 of 03/05/1976, publ. 12/23/1980, BI No. 47), containing two rigid rectangular clamps, each of which is equipped with an end wall made in the form of a frame and connected to the clamp by four double-hinged links mounted in pairs on the vertical rods of the end wall and interacting with the stops located on the clamp.

In this device, protection against mechanical damage is carried out only from the ends, and its length is not, as there is no protection against atmospheric influences and insufficient rigidity along the length of the container. This design is complicated by clamps that are removed from the end walls, so there is a need for them to be pivotally connected by links that are interconnected by flexible connections. The presence of articulated joints, which are triggered during use, and other joints complicates the design and does not have the required stiffness required during storage and storage. This design does not allow transporting lumber of various sizes and there is no possibility to stack loads in several rows.

The basis of the invention is the creation of a container for transporting long loads with the prevention of mechanical damage to the cargo and protection against weathering with the possibility of stacking during storage by creating structural rigidity in the longitudinal and transverse directions of the container.

The problem is solved in that the collapsible container for storing and transporting long loads, mainly lumber, contains four rigid rectangular clamps with load-gripping elements, two of which are equipped with an end wall, and two others are located in the longitudinal direction at equal distances from each other, each which are made of two horizontal lines, supported by two verticals, between which are located plates, fastened together and connecting the end walls to each other. The strapping of the clamp on the outside is made of profiled material, the horizontal and vertical of which are interconnected by two bolt joints along the width of the profile material, and the extreme surfaces from the ends have holes for fixing containers to each other. The binding of the clamp on the inside of the container is made of wood similarly to the binding on the outside. These strapping fasten together plates connecting the end surfaces of the container uniformly along the entire transverse perimeter, and the clamps are evenly distributed in the longitudinal direction of the container, while the ratio of the height and width of the container can be equal to one.

The external harness of the channels and the inner of the clamp tree are interconnected at regular intervals, giving it a shape in the form of a rectangle or square and ensuring the strength of the connection in cross section. A set of boards, bonded together, forms the lower, upper and two side walls of the container, provides the connection of the end walls and rigidity in the transverse and longitudinal direction. The arrangement of the harnesses in the longitudinal direction through equal distances ensures uniform load distribution in the longitudinal direction, i.e. horizontally. All vertical elements of the external and internal harnesses work for strength, as horizontal elements rely on vertical ones; therefore, horizontal elements of two strands are longer than vertical ones. The rigidity of the connection of the external strapping is enhanced by fastening the horizontal lines and verticals to each other with the help of two bolts along the width of the channel. The external strapping of each clamp contains eyes in each channel, located on the upper wall not only at the ends, but also uniformly along the length of the container, which allows different ways of securing the slings when loading and unloading the container, providing ease of use. On the end surfaces of the external strapping in cross section there are openings for connecting the containers along each other in length, which makes it possible to arrange the container differently during transportation and storage, both in length and in width.

The end walls are formed by the vertical arrangement of the boards, also providing vertical strength, which eliminates distortions during assembly and operation, increasing the rigidity in the cross section and in general the container structure.

There is an opening on each end wall, which are diagonally opposite to each other, and are intended for ventilation. This makes it possible to transport goods that are subject to increased environmental requirements.

All elements of the container without waste are used later in the construction of, for example, a manor house, which excludes empty transportation of vehicles. This container design allows you to transport lumber of various sizes, protects it from mechanical damage and atmospheric influences, which increases the usability of the container, and during storage allows you to stack loads.

Figure 1 shows the proposed container, General view; figure 2 is the same, a top view; figure 3 - section aa, the connection of the harnesses of the clamp on the outer and inner sides of the container with the end wall; figure 4 is the same side view, without end wall (or cross section of the container); figure 5 - connection of horizontal and vertical elements of the strapping of the clamp on the outside of the container.

The collapsible container contains clamps 1, consisting of two strands of external 2 and internal 3 (figure 4), each of which contains two horizontal and two verticals. Between the external and internal strapping are plates 4, fastened together by means of a dowel and connecting the end walls to each other (figures 1 and 4). The horizontal and vertical strapping of the clamp on the outside of the container are fastened together by two bolted joints along the width of the profile material (figure 5). The harnesses are evenly fastened with bolted joints 5 along the entire transverse perimeter of the container (figure 4). The clamps are evenly distributed in the longitudinal direction of the container (figure 1). The plates of the upper, lower and side walls from the ends have a groove 6 along the entire transverse perimeter for connection with the end walls 7 (figures 1 and 3).

The container is collected as follows. Each wall can be assembled separately, i.e. lower, upper, two lateral and two end or all at once. In the cross section of the container, metal channels are laid, facing outwardly, onto which 6 m long boards are laid in the longitudinal direction (Fig. 1), fastened together with a key. Then, in the direction of the metal channels, wooden blocks are laid, and all this is fixed to each other evenly with bolted joints. The bars form the inner strapping of the clamp, and the channel - the outer strapping. The clamps are located at the ends and at regular intervals along the length of the container. There are at least four such clamps, depending on the container load. Thus, a wall panel is formed, along the perimeter of which there is a groove, i.e. a recess for keyway with the boards of the mating walls (figure 3). Then, to the external piping of the channels, vertical channels (Fig. 3) are attached, having a box-shaped shape, the end surface of which abuts against the base of the horizontal channel and is fastened with it using two bolts located in width. Then, in the longitudinal direction, the sheathing is made of boards 6 m long, fastened together with a key and fixed on the outer and inner sides of the container with channels and bars, respectively, which are evenly stitched through the bolts evenly from the outside of the container.

Thus, two side walls of the container are formed. Similarly, the upper wall foam is assembled with channels, which lie on the vertical channel of the box type, which ensures strength in the vertical direction. Lastly, the end walls of the container are attached, which may or may not be present at all, depending on the type of material being filled. If these are lumber of the same size, then they are not needed, but if the completeness is different, then they are easily installed.

The end walls represent a set of boards interconnected by a key and vertically mounted and nailed to the inner strapping of the clamp, bounding the end surfaces.

Each end surface has an opening (300 by 300) mm in size, diagonally opposed to each other and intended for ventilation, which ensures the transportation of wooden structures, which are subject to high demands from atmospheric conditions and also protection against mechanical stress.

The transverse strapping of the channels facing outward, allows you to capture the forklift, and from above, having eyes, it is possible to secure the sling elements in various places. This increases the convenience of loading and unloading. The container can be loaded and unloaded through the end walls, and the end wall boards can serve as an auxiliary tool that fits inside the channel for convenience when installing containers in several rows during storage or intermodal transport. Sheathing with 6 m long boards, i.e. in the longitudinal direction of the container with evenly spaced clamps, and the presence of end walls make it possible to create the necessary rigidity, which protects the load from mechanical damage and protects it from atmospheric influences.

The container has dimensions (2500 × 2500 × 6000) mm and can accommodate a set of manor house. The dimensions of the container, depending on the need, can be increased in length by no more than 500 mm. The carrying capacity of the container is 24 tons. The square cross-section allows you to optimally fill the space during storage and intermodal transport. The container does not have protruding elements, therefore, during storage and transportation a different arrangement is possible. In the end walls of the harness, on the outside of the container, holes are made for attaching a container of a similar design with an increase in length, which is also important during storage and transportation. The container can be equipped with lumber of both one and various sizes. The container is intended for single use, which excludes empty transportation.

The proposed design of the container is simple, not time-consuming to assemble, allows you to assemble it directly on the spot, while it is possible to assemble the walls in advance. It is durable, allows you to install the container in several rows during transportation and storage, as well as transport lumber of various sizes, saving the load from the effects of external conditions and mechanical damage.
