Description

Technical Field

[0001] The utility model belongs to the technical field of railway hopper cars, and more specifically, relates to an inner lining device for a hopper car and the hopper car. Background Art

[0002] The temperature in northern my country is low in winter. During long-term transportation, coal often freezes and sticks to the carriage. In severe cases, the entire car freezes, making unloading difficult and inefficient. The current methods for cleaning and preventing frozen coal mainly include spraying antifreeze in the coal carriage and mechanically or manually knocking on the carriage wall. Spraying antifreeze has been used in most enterprises that use open cars to transport coal, and has a certain effect. Since the end and bottom hopper areas of the coal hopper car are inclined structures without water collection function, the sprayed antifreeze has a poor hanging effect on the wall. After the instantaneous impact of falling coal, the already fragile antifreeze coating is even less. Therefore, spraying antifreeze has limited effect on the antifreeze of coal hopper cars. The main method for unloading frozen coal from coal hopper cars is to manually knock on the carriage wall. This method not only increases coal transportation time and labor costs, but also easily damages the car body, shortens the service life of the vehicle, and increases vehicle maintenance costs.

[0026] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0027] like Figures 1 to 6 As shown, the utility model provides a lining device for a hopper car, comprising:

[0028] Lining plate 1, wherein the lining plate 1 is an anti-sticking plate;

[0029] The mounting structure is used to mount the liner 1 on the inner wall of the compartment of the hopper car, so that the liner 1 is in close contact with the inner wall of the compartment.

[0030] Specifically, Figure 1 As shown, in order to solve the problem of frozen coal sticking to coal hopper cars in winter, the lining device for hopper cars provided by the utility model has a lining plate 1, which is an anti-sticking plate and is installed on the inner wall of the hopper car through a mounting structure. The anti-sticking plate can effectively prevent the frozen coal from sticking to the car body, saving time and labor costs for coal transportation in winter; and it has a simple structure, light weight, and easy installation; at the same time, the impact resistance of the anti-sticking plate can also protect the car body, avoid damage to the car body caused by knocking during manual unloading, and alleviate the impact of falling coal blocks on the car body during loading.

[0031] Furthermore, there is no limitation on the specific components of the installation structure, as long as the lining plate 1 can be fixed to the inner wall of the carriage.

[0032] Optionally, the anti-sticking plate is made of ultra-high molecular weight polyethylene.

[0033] Specifically, ultra-high molecular weight polyethylene has excellent wear resistance, corrosion resistance, self-lubrication, anti-stickiness, impact resistance, low density, and its wear resistance is 1 to 7 times that of steel plates. Its density is only 1 / 9 of that of steel. It can be used for hopper and silo linings for materials such as coal, lime, and cement.

[0034] Optionally, the lining plate 1 is installed on the inner side of the end wall component 6 of the carriage through the mounting structure.

[0035] Furthermore, a lining plate 1 may be provided on the side wall component 7. Since, in actual implementation, the freezing and adhesion of the side wall component 7 is slight, while the freezing and adhesion of the end wall component 6 is serious, the lining plate 1 is only provided on the end wall component 6 in this embodiment.

[0036] Alternatively, if Figure 1 , 2 As shown, the mounting structure includes a first mounting structure, which includes a plurality of first studs and a plurality of first nuts 13. A plurality of first holes 9 are provided on the liner 1. The first studs are fixedly connected to the end wall component 6. The first studs pass through the first holes 9 and are threadedly connected to the first nuts 13.

[0037] Specifically, considering that the thermal deformation temperature of ultra-high molecular weight polyethylene material is only 85°C, the device must be installed after the welding of the vehicle body steel structure is completed. However, due to the poor flatness of the end wall component 6 after welding deformation, and the large number of fasteners, it is difficult to ensure the positioning accuracy of each bolt if bolts are used to fix the components of the device. Therefore, the first stud and the first nut 13 are used to fix the large surface of the liner to the inner wall of the end wall component 6.

[0038] Furthermore, a plurality of first studs are arranged in an array on the inner wall of the end wall.

[0039] In this embodiment, the first hole 9 is a countersunk hole, the first stud is a standard part, the first nut 13 is cylindrical, the upper surface of the first nut 13 is grooved to facilitate screwing with a tool, and the first nut 13 is spot welded after installation. After installation, the upper surface of the first nut 13 is flush with the surface of the liner 1 to prevent coal from sticking and accumulating.

[0040] In this embodiment, the first stud and the first nut are both made of stainless steel.

[0041] Alternatively, if Figure 1 , 3 As shown, at least two lining plates 1 are arranged on each of the end wall components 6, and the mounting structure also includes a second mounting structure, which includes an intermediate pressure strip 2, the cross-section of the intermediate pressure strip 2 is T-shaped, and a gap is left between two adjacent lining plates 1. The web of the intermediate pressure strip 2 is arranged in the gap between the two adjacent lining plates 1, and the wing plate of the intermediate pressure strip 2 is pressed on the edge of the lining plate 1, and the intermediate pressure strip 2 is fixedly connected to the end wall component 6.

[0042] Specifically, since the ultra-high molecular weight polyethylene sheet is soft, a liner 1 with too large an area will cause inconvenience in transportation and installation, so this embodiment adopts a splicing structure of multiple liner 1 to facilitate transportation and installation of the liner 1. Furthermore, the middle layer 2 can prevent the edge of the liner 1 from warping and prevent water in the coal from corroding the end wall component 6.

[0043] Alternatively, if Figure 4 As shown, the mounting structure also includes a third mounting structure, which includes a corner bead 3, which is arranged at the connecting position of the end wall component 6 and the side wall component 7, and the cross-section of the corner bead 3 is L-shaped. The edge of the lower flange of the corner bead 3 is provided with a stepped notch 8 matching the thickness of the lining plate 1, and the stepped notch 8 of the corner bead 3 is pressed on the edge of the lining plate 1, the web of the corner bead 3 is fixedly connected to the side wall component 7, and the lower flange of the corner bead 3 is fixedly connected to the end wall component 6.

[0044] Specifically, the corner bead 3 can prevent the edge of the liner 1 from warping, prevent water in the coal from corroding the end wall component 6 and the side wall component 7, and prevent frozen coal from sticking to the corner formed by the end wall component 6 and the side wall component 7.

[0045] Optionally, a first gap is left between the web of the middle bead 2 and the edge of the lining plate 1 , and a second gap is left between the side wall of the stepped notch of the corner bead 3 and the edge of the lining plate 1 .

[0046] Specifically, considering that the linear expansion coefficient of the ultra-high molecular weight polyethylene plate is relatively large, a first gap is left between the web of the middle bead 2 and the edge of the liner 1, and a second gap is left between the side wall of the stepped notch of the corner bead 3 and the edge of the liner 1 to prevent it from deforming and bulging due to heat.

[0047] Alternatively, if Figure 3 As shown, the middle layer 2 is provided with a plurality of second holes 10; Figure 4 As shown, the web of the corner strip 3 is provided with a plurality of third holes 11, the lower flange of the corner strip 3 is provided with a plurality of fourth holes 12, the end wall component 6 is fixedly provided with a plurality of second bolts 4 corresponding to the second holes 10, and a plurality of fourth bolts corresponding to the fourth holes 12, the side wall component 7 is fixedly provided with a plurality of third bolts corresponding to the third holes 11, the second bolt 4 passes through the second hole 10 and is threadedly connected to the second nut 5, the third bolt passes through the third hole 11 and is threadedly connected to the third nut, and the fourth bolt passes through the fourth hole and is threadedly connected to the fourth nut.

[0048] Optionally, the middle bead 2 and the corner bead 3 are made of ultra-high molecular weight polyethylene.

[0049] The utility model also provides a hopper car, comprising a car body and a lining device for the hopper car, wherein the lining plate 1 is installed on the inner wall of the car body of the hopper car through the installation structure.

[0050] The various embodiments of the utility model have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
