Description

Technical Field

[0001] The utility model relates to the field of steel, and in particular to a special steel seat frame for railway steel coil transportation. Background Art

[0002] At present, in the steel industry, the proportion of steel coil products is very large. Although steel coils have many types, such as cold-rolled coils and hot-rolled coils, and the sizes are also different, the thickness, width, outer diameter and inner diameter of the steel coils are not the same, and there are many types, but they are generally curled into a cylindrical shape, so they are easy to roll during transportation, and the weight of the steel coils is several tons or even dozens of tons. If a rollover accident occurs, it will be a major accident. Moreover, the current road transportation heavy truck load is basically dozens of tons, so a truck can transport at most three to four coils, while for large steel coils of dozens of tons, only one coil can be transported. Therefore, it is not easy to transport steel coils by truck, which is dangerous and inefficient. Therefore, truck transportation of steel coils is only suitable for short-distance transportation. Railway transportation is most suitable for steel coil transportation because of its large load capacity and fast speed. Therefore, railway transportation is the first choice when transporting steel coils across the country.

[0003] However, during railway transportation, the rolling of steel coils during transportation is still an inevitable problem. At present, in order to prevent the rolling of steel coils during transportation, old methods such as sleepers and rubber supports are used, but the effect is not ideal. Steel coils often roll during transportation due to insufficient strength or displacement during transportation. Although railway transportation will not cause accidents due to the rolling of steel coils, the rolling of steel coils will still damage the appearance of the steel coils and affect the delivery of goods. At the same time, the rolling of steel coils will also increase the difficulty of loading and unloading of steel coils. In addition, anti-rolling measures such as sleepers and rubber supports are still difficult to control when loading steel coils, because there is no reference standard, the position is not easy to place, and the effect is useless if the spacing is large. If the spacing is small, the steel coils will be suspended, and the anti-rolling effect will still be greatly reduced. Utility Model Content

DETAILED DESCRIPTION

[0034] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0035] Example 1

[0036] According to the utility model, a special steel frame for railway steel coil transportation is provided. Figure 1-6 As shown, it includes a basic frame 1, a hump 2, a groove 3, a positioning block 4 and a flip-up pillow 5. Figure 1 As shown, several rows and columns of triangular humps 2 are processed in the form of rows and columns on the front of the basic frame 1. Two adjacent humps 2 in the same row form a groove 3, so that several rows and columns of grooves 3 are formed. Based on the formation principle of the grooves 3, the number of rows of grooves 3 is the same as the number of rows of humps 2, and the number of columns will be 1 less than the number of columns of humps 2. The steel coils will be placed inside the grooves 3 in the same column. Depending on the length of the steel coil, one steel coil may occupy 2-3 grooves 3. The bottom of the humps 2 at the four corners of the basic frame 1 are processed with lifting ears 6, and the lifting ears 6 are hook-shaped, as shown in the figure. Figure 2 The lifting lug 6 is convenient for lifting by ropes, and of course, lifting by special clamps can be more convenient and quick, and can also achieve automated lifting.

[0037] Several positioning blocks 4 are processed on the front and rear crossbeams of the basic frame 1. The positioning blocks 4 will be used for internal positioning of the train open car compartment, and can also lock the position of the overall structure in the compartment, so as not to cause sliding during the operation of the train. The positioning block 4 is composed of three steel plates: the top positioning plate 41, the bottom positioning plate 42 and the vertical positioning plate 43, and the thickness of the steel plate is 10 mm. Since the positioning block 4 is fixed in the position in the compartment, it may vary depending on the compartment, so more models will be required for adaptation. The top positioning plate 41 and the bottom positioning plate 42 need to be welded to the top and bottom of the basic frame 1 according to the position of the compartment positioning pile, and the vertical positioning plate 43 is welded to the sides of the top positioning plate 41 and the bottom positioning plate 42 respectively to reinforce the top positioning plate 41 and the bottom positioning plate 42. A foot pad 11 is provided at the bottom of the basic frame 1. The foot pad 11 is consistent with the thickness of the bottom positioning plate 42. The function of the foot pad 11 is to balance the protrusion of the bottom positioning plate 42 to ensure that the basic frame 1 can be placed stably.

[0038] The hump 2 includes a large hump 201 and a small hump 202. There is no restriction on how to set the specific size of the hump. The size of the steel coils adapted to different models varies. The large hump 201 and the small hump 202 include an inner working arm and an outer working arm. Figure 1 As shown, four large humps 201 are respectively arranged around the basic frame 1, and four small humps 202 are arranged in the middle of the basic frame 1. Flippable cushions 5 are installed in the four small humps 202 in the middle. The flippable cushions 5 can change the size of the hump 2 in which they are located to adapt to the placement of different types of steel coils.

[0039] The reversible pillow 5 is connected to the hump 2, and the reversible pillow 5 rotates and switches between the idle state and the working state; when the reversible pillow 5 is in the idle state, the reversible pillow 5 is located between two adjacent humps 2, and the size of the groove 3 formed by the two adjacent humps 2 is the maximum value, and an extra-large steel coil can be placed here; when the reversible pillow 5 is in the working state, the bottom of the reversible pillow 5 is attached to the first working surface on the hump 2, and the formed second working surface is flush with the first working surface of the adjacent large hump 201, and a larger hump 2 can be formed in cooperation with the original hump 2, and the size of the groove 3 is the minimum value, at this time two large and medium-sized steel coils can be placed.

[0040] like Figure 2 As shown, the inner working arm of the hump 2 is longer than the outer working arm and overlaps the top of the outer working arm, and the two working arms form a 90-degree angle. This can cope with the huge pressure caused by the rolling tendency of the steel coil due to inertia caused by acceleration and deceleration during the transportation of the steel coil.

[0041] like Figure 4 The bottom of the hump 2 is provided with a hinge base 20, which is composed of two L-shaped steel plates 21 installed back to back with a spacing of 30 mm; the L-shaped steel plate is 10 mm thick and 50 mm wide. The L-shaped steel plate 21 includes a short side 23 and a long side 22, the long side is 50 mm, and the short side is 40 mm long. The short side 23 is connected to the first working surface, and the first working surface is perpendicular to the long side 22. The long side 22 has a hole in the center, and a hinge shaft is installed in the hole.

[0042] like Figure 5As shown, the flip pillow 5 includes a hinge arm 51, a main body 52 and a rubber pad. The main body 52 is the working body and will be subjected to huge pressure during operation. It must be made of a steel plate of not less than 10 mm. The hinge arm 51 can be made of a 3-5 mm steel plate. The hinge arm 51 is connected to the bottom of the main body 52, and a rubber pad is connected to the top of the main body 52. ​​When the flip pillow 5 is flipped to the working position, its back side just fits against the rubber pad on the hump 2, so that the rotatable pillow 5 can form a whole with the hump 2. A hinge rotation hole 54 is provided on the hinge arm 51, and the hinge arm 51 is connected to the hinge shaft through the hinge rotation hole 54, and the size of the hinge rotation hole 54 is greater than the diameter of the hinge shaft. In this way, when the flip pillow 5 is in the working position, the hinge arm 51 has some room for movement on the hinge axis. When the rotatable pillow 5 is squeezed, the force will be transmitted to the hump 2 through the back of the rotatable pillow 5 without causing the hinge arm 51 to be subjected to stress.

[0043] More specifically, the reversible pillow 5 is connected to the hump 2 via a hinge, and the reversible pillow 5 can be switched between the idle position and the working position by rotating the hinge. It should be noted that the hinge can theoretically be set on either the front or rear side of the hump 2, but usually, in order to improve the strength of the hump 2, the hump 2 is processed near the crossbeam of the nine-square grid of the basic frame 1. If the hinge is set incorrectly, the reversible pillow 5 will interfere with the crossbeam of the basic frame 1 when it is flipped to the idle position, making it impossible to flip to the idle position, so the hinge should be set on the side away from the crossbeam of the basic frame 1.

[0044] Example 2

[0045] The second embodiment is completed on the basis of the first embodiment, and the main difference is that the present embodiment has three rows of humps, and the size is larger than that of the first embodiment, specifically:

[0046] like Figure 7 As shown, the outermost eight humps are small humps 202, and the middle four humps are large humps 201. The right working surface of the large hump 201 is provided with a rotatable pillow 5. The two arms of the small hump 202 are of different lengths, and the inner arm is longer and overlapped on the outer arm. This can cope with the huge pressure caused by the rolling tendency of the steel coil due to inertia caused by acceleration and deceleration during transportation. The middle large hump 201 has two arms of equal length butt joint. Since both sides of the middle large hump 201 are working surfaces, the stress on both sides can be offset during operation, so they are equal length arms. The size of this embodiment can accommodate more steel coils, and is mainly suitable for large, medium and small steel coils.

[0047] Example 3

[0048] This embodiment 3 is completed on the basis of embodiment 1. The main difference is that there are four rows of humps in this embodiment, and the size is larger than that of embodiment 2. Specifically: the outermost 8 humps are small humps 202, and the middle 8 humps are large humps 201. The working surface adjacent to each large hump 201 and small hump 202 is provided with a rotatable pillow 5. The two arms of the small hump 202 are of different lengths. The inner arm is longer and overlapped on the outer arm. This can cope with the huge pressure caused by the rolling tendency of the steel coil due to inertia caused by acceleration and deceleration during transportation. The middle large hump 201 is connected with two arms of equal length. Since both sides of the middle large hump 201 are working surfaces, the stress on both sides can be offset during operation, so they are equal length arms. The size of this embodiment can accommodate more steel coils, and the groove size is also slightly smaller. It is mainly suitable for medium, small and micro steel coils.
