Description

Technical Field

[0001] The utility model relates to the technical field of bottom side-dumping mine cars, and specifically relates to a bottom side-dumping mine car. Background Technique

[0002] Bottom-dumping mine cars and fixed mine cars are both the main transportation equipment for transporting ore and gangue on the ground and in the underground roadway of coal mines. The bottom-dumping mine car mainly consists of a car body, a frame, a buffer, a coupler, axles, etc. The car body is generally made of metal structure, with buffer devices at both ends. There is also a coupler for connecting mine cars to mine cars and mine cars to locomotives. The car body of the bottom-dumping mine car is connected to the frame by axles. The unloading principle of the bottom-dumping mine car is as follows:

[0003] When the mine car body is suspended and moves forward along the idler rollers, the bottom frame of the mine car automatically opens downward by its own weight and the weight of the ore carried. The unloading wheels at the rear end of the car body bottom frame roll downward along the unloading curved rail, and the car bottom door gradually opens wide. Due to the weight of the ore carried and the self-weight of the mine car bottom frame, the mine car receives a horizontal thrust, which pushes the train to continue moving forward. When the mine car passes through the unloading center point, all the ore is unloaded. The unloading wheels roll over the inflection point of the curved rail and gradually move upward, and the frame and the car body gradually close.

[0004] There is a kind of car body bottom-dumping mine car on the market at present, which is welded by 16Mn steel. Compared with Q235A steel, the strength of 16Mn steel is increased by 50%, the atmospheric corrosion resistance is increased by 20 - 38%, and the low-temperature impact toughness is also superior, and the price is not expensive;

[0005] However, in actual use, due to the great impact on both sides of the car body during loading and unloading of ore, the car body is severely deformed, resulting in a short service life of the mine car, a large amount of maintenance work, and poor reliability of the transportation system. If HD500 steel plates are used, the trial effect is very good, and the service life is increased by 1.5 - 2 times compared with 16Mn steel. However, this kind of steel is relatively expensive and the use cost is high. Based on this, in the design of the side plates of the car body, by adding 16Mn steel reinforcing plates to form a rigid frame structure, its strength is greatly enhanced, the deformation is reduced, not only the maintenance amount is reduced, but also the service life of the mine car is extended. Based on this, a bottom side-dumping mine car is provided. Content of the Utility Model

Detailed Embodiment

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1 to 4, in the embodiment of the present utility model, a bottom-side unloading mine car includes a mine car main body 1 composed of a carriage 101, a car chassis 102, a connecting hinge 103, and side rails 104. The car chassis 102 is distributed at the bottom of the carriage 101, and one side of the car chassis 102 is rotatably connected to the bottom of one side of the carriage 101 through the connecting hinge 103. The side rails 104 are symmetrically welded and fixed on both sides of the outer wall of the carriage 101. An impact-resistant component 2 is arranged on the inner and outer sides of the carriage 101, and the impact-resistant component 2 is used to increase the impact-resistant strength of the carriage 101;

[0028] The impact-resistant component 2 includes a bottom plate 201, a plugging groove 202, an n-shaped reinforcing plate 203, and a 7-shaped plugging block 204;

[0029] The bottom plate 201 is symmetrically welded and fixed on both sides of the inner wall of the carriage 101 and at a position close to the bottom end of the carriage 101. The plugging groove 202 is opened at the top of the bottom plate 201 and penetrates to the bottom of the bottom plate 201;

[0030] The 7-shaped plugging block 204 is fixed to the bottom end of the n-shaped reinforcing plate 203, and the top of the n-shaped reinforcing plate 203 is sleeved on the outside of the top of the side plate of the carriage 101. The 7-shaped plugging block 204 is plugged inside the plugging groove 202. The n-shaped reinforcing plate 203 is used to further increase the side thickness of the carriage 101 and improve the side impact-resistant strength of the carriage 101;

[0031] The impact-resistant component 2 further includes a connecting plate 205, a fixed side plate 206, and a locking bolt 208;

[0032] The fixed side plates 206 are symmetrically welded and fixed on both sides of the outer wall of the carriage 101 and above the side rails 104. The connecting plate 205 is fixed to the bottom end of the vertical bending part of the top of the n-shaped reinforcing plate 203 and is attached to the upper surface of the fixed side plate 206;

[0033] Mounting holes 207 are correspondingly opened on the connecting plate 205 and the fixed side plate 206. The locking bolt 208 sequentially penetrates through the mounting holes 207 on the connecting plate 205 and the fixed side plate 206 and is tightened with a nut to realize the installation and fixation of the n-shaped reinforcing plate 203;

[0034] A plurality of plugging grooves 202 are uniformly opened along the horizontal transverse direction of the bottom plate 201. The transverse width of the 7-shaped plugging block 204 is smaller than the transverse width of the n-shaped reinforcing plate 203, and two adjacent horizontally transversely distributed n-shaped reinforcing plates 203 are mutually attached;

[0035] The n-shaped reinforcing plate 203, the 7-shaped plugging block 204, and the connecting plate 205 are integrally formed by stamping and bending a steel plate.

[0036] In this embodiment: When this mine car is in use, n-shaped reinforcement plates 203 can be added on both sides of the inner wall of the carriage 101 to enhance the impact resistance of the sides of the carriage 101 (it should be noted that during ore loading and unloading, the impact of ore on both sides of the carriage is the greatest). The installation operation of the n-shaped reinforcement plate 203 is as follows:

[0037] It only needs to align the vertical part of the 7-shaped insertion block at the bottom of the n-shaped reinforcement plate 203 with the insertion slot 202 and insert it. When the vertical part of the 7-shaped insertion block is completely inserted into the inner side of the insertion slot 202, at this time, the connecting plate 205 fits on the upper surface of the fixed side plate 206, and the mounting holes 207 on the connecting plate 205 are aligned with the mounting holes 207 on the fixed side plate 206. Then, lift the locking bolt 208 and insert it into the mounting hole 207, and tighten it with a nut to complete the installation operation of the n-shaped reinforcement plate 203. The cooperation between the insertion slot 202 and the 7-shaped insertion block can limit the horizontal direction of the n-shaped reinforcement plate 203, and the locking bolt 208 can achieve the vertical limit of the n-shaped reinforcement plate 203, thereby making the installation of the n-shaped reinforcement plate 203 stable;

[0038] During ore loading and unloading, the ore directly contacts the n-shaped reinforcement plate 203. The n-shaped reinforcement plate 203 is processed from 16Mn steel plate. By adding a rigid frame structure composed of multiple n-shaped reinforcement plates 203, the strength of the side of the mine car is greatly enhanced, reducing deformation, not only reducing the maintenance volume, but also extending the service life of the mine car;

[0039] In addition, through the independent structure setting of multiple n-shaped reinforcement plates 203, when a certain n-shaped reinforcement plate 203 is deformed, only a single n-shaped reinforcement plate 203 needs to be replaced, and the maintenance is more flexible and convenient.

[0040] Please refer specifically to Figures 1 to 4 , an n-shaped shock-absorbing rubber pad 209 is adhesively fixed to the inner side of the n-shaped reinforcement plate 203. The inner wall of the n-shaped shock-absorbing rubber pad 209 fits on the inner and outer surfaces of the carriage 101, and the thickness of the vertical part of the 7-shaped insertion block 204 matches the horizontal thickness of the insertion slot 202;

[0041] The vertical side of the n-shaped reinforcement plate 203 is flush with the side of the bottom plate 201;

[0042] A groove matching the horizontal part of the 7-shaped insertion block 204 is formed at the bottom of the n-shaped shock-absorbing rubber pad 209, and the horizontal width of the n-shaped shock-absorbing rubber pad 209 matches the horizontal width of the n-shaped reinforcement plate 203.

[0043] In this embodiment: through the arrangement of the n-type shock-absorbing rubber pad 209, a buffer layer is formed between the n-type reinforcing plate 203 and the side plate of the carriage 101. In this way, when the n-type reinforcing plate 203 is impacted by ore, the impact force transmitted to the side plate of the carriage 101 can be reduced through the n-type shock-absorbing rubber pad 209, further improving the protection effect on the side plate of the carriage 101;

[0044] In addition, through the structure that the vertical side surface of the n-type reinforcing plate 203 is flush with the side surface of the bottom plate 201, it is possible to prevent the ore sliding downward from contacting the upper surface of the bottom plate 201 and causing impact, and at the same time avoid the situation of ore residue during unloading.

[0045] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
