Technical Field
[0001] This utility model relates to the field of mining car technology, specifically a mining car that facilitates unloading. Background Technology
[0002] Mining cars are narrow-gauge railway transport vehicles used in mines to transport bulk materials such as coal, ore, and waste rock. They are generally pulled by locomotives or winches. Mining cars are classified into five main categories according to their structure and unloading method: stationary mining cars (material cars, flatbed cars), tipper mining cars, single-sided curved rail side-discharge mining cars, bottom (side) unloading mining cars, and shuttle mining cars. Among them, the tipper mine car has a U-shaped or V-shaped cross-section design, with arc-shaped rolling rings at both ends, supported on the tipping rail of the frame. After the stop plate that locks the car is opened, the car can tilt to either side at ≥40° along the tipping rail and automatically unload the material by gravity. Its core feature is that it achieves rapid unloading by tipping the car, without the need for auxiliary facilities. The unloading can be completed by manually operating the stop plate, saving time and energy.
[0003] However, in actual use, the tipper mine car is easily deformed by the impact of the ore, and the semi-circular welded ends are prone to cracking. Repeated repairs will still result in recurrence, which means that the service life of the car is short and the replacement of the entire car is time-consuming and labor-intensive. Based on this, a mine car that is easy to unload is provided. Utility Model Content
[0004] The purpose of this utility model is to provide a mine car that facilitates unloading, in order to solve the problems mentioned above.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a mine car for easy unloading, comprising a tipping mine car consisting of a car body, an arc-shaped rolling ring, and a frame. The arc-shaped rolling ring is symmetrically fixed at both ends of the car body. The car body is distributed inside the frame and placed on the tipping rail of the frame via the arc-shaped rolling ring. The inner and outer sides of the car body are provided with lining components. The lining components include two semi-V-shaped inner buckets, which are symmetrically distributed inside the car body. The hopper structure formed by the two semi-V-shaped inner buckets provides a receiving point for the ore, preventing the ore from directly impacting the car body. The maintenance workload is reduced by replacing the semi-V-shaped inner buckets individually.
[0006] As a further embodiment of this utility model: the inner lining assembly also includes a concave flange, a connecting arm, a concave fixing sleeve, and fastening bolts; The concave folded edge is fixed to the top of the semi-V-shaped inner hopper, and the concave folded edge extends to the outside of the vehicle body; The concave fixing sleeve is fixed to both sides of the carriage, the connecting arm is fixed to the bottom of the concave folded edge and passes through the concave fixing sleeve, and the fastening bolt passes through the concave fixing sleeve and is threadedly connected and fixed to the connecting arm, so as to realize the connection and fixation between the connecting arm and the concave fixing sleeve. The detachable connection structure, consisting of a connecting arm and a concave fixing sleeve, allows for the assembly and disassembly of the semi-V-shaped inner hopper.
[0007] As a further embodiment of this utility model: multiple sets of the connecting arm and the concave fixing sleeve are evenly arranged along the long side of the concave fold, and a single set of the connecting arm and the concave fixing sleeve is connected and fixed by multiple fastening bolts.
[0008] As a further improvement of this utility model: multiple longitudinally distributed vertical reinforcing ribs are symmetrically welded and fixed at both ends of the inner wall of the carriage, and the bottom of the vertical reinforcing ribs is welded and fixed to the semi-circular bottom and side of the carriage.
[0009] As a further improvement of this utility model: multiple horizontally distributed V-shaped reinforcing ribs are welded and fixed to the bottom and sides of the semi-circular arc of the carriage, and the inner surface of the V-shaped reinforcing ribs is in contact with the outer surface of the semi-V-shaped inner bucket. The vertical reinforcing ribs are fitted to the end face of the semi-V-shaped inner hopper, and the center line of the vertical reinforcing ribs distributed in the middle is aligned with the splicing surface of the two semi-V-shaped inner hoppers.
[0010] As a further embodiment of this utility model: the lower surface of the concave folded edge is in contact with the top of the carriage, the vertical reinforcing rib, and the V-shaped reinforcing rib, and the outer wall dimension of the concave folded edge is larger than the outer wall dimension of the carriage.
[0011] Compared with the prior art, the beneficial effects of this utility model are: By setting up an inner lining component, a hopper structure is formed by two semi-V-shaped inner hoppers. The ore is placed directly inside the hopper structure, so the ore does not directly impact the truck body, effectively avoiding impact deformation and damage to the truck body. Furthermore, by removing the fastening bolts and tilting the truck body, the semi-V-shaped inner hopper, concave folded edge, and connecting arm slide down and fall off under their own weight, which can be achieved by disassembling the semi-V-shaped inner hopper. After that, a new set of semi-V-shaped inner hoppers, concave folded edges, and connecting arms can be installed. The replacement operation of the semi-V-shaped inner hopper is simple and convenient.

Detailed Implementation
[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figures 1-3 In this embodiment of the utility model, a mine car that is easy to unload includes a tipping mine car 1 consisting of a car body 101, an arc-shaped rolling ring 102, and a frame 103. The arc-shaped rolling ring 102 is symmetrically fixed at both ends of the car body 101. The car body 101 is distributed inside the frame 103 and placed on the tipping rail of the frame 103 through the arc-shaped rolling ring 102. The inner and outer sides of the car body 101 are provided with an inner lining assembly 2. The inner lining assembly 2 includes two semi-V-shaped inner buckets 201. The two semi-V-shaped inner buckets 201 are symmetrically distributed inside the car body 101. The hopper structure formed by the two semi-V-shaped inner buckets 201 provides a receiving point for the ore and is used to prevent the ore from directly impacting the car body 101. The maintenance workload is reduced by replacing the semi-V-shaped inner buckets 201 individually. The inner lining assembly 2 also includes a concave flange 202, a connecting arm 203, a concave fixing sleeve 204, and a fastening bolt 205; The concave folded edge 202 is fixed to the top of the semi-V-shaped inner hopper 201, and the concave folded edge 202 extends to the outside of the carriage 101; The concave fixing sleeve 204 is fixed on both sides of the carriage 101, the connecting arm 203 is fixed to the bottom of the concave folded edge 202 and passes through the concave fixing sleeve 204, and the fastening bolt 205 passes through the concave fixing sleeve 204 and is threadedly connected and fixed to the connecting arm 203, so as to realize the connection and fixation between the connecting arm 203 and the concave fixing sleeve 204. The detachable connection structure of the connecting arm 203 and the concave fixing sleeve 204 is used to realize the assembly and disassembly of the semi-V-shaped inner hopper 201.
[0016] In this embodiment, it should be noted that: concave brackets 105 are fixed at both ends of the carriage 101 above the arc-shaped rolling rings 102, and stop plates 104 are rotatably installed at the top of both ends of the frame 101. The carriage 101 is fixed in an upward-facing state by rotating the stop plates 104 into the concave brackets 105. When the carriage 101 is flipped, the stop plates 104 are manually rotated to separate them from the concave brackets 105, thereby releasing the lock of the carriage 101. Then the carriage 101 can be manually pushed to flip. When this tipper mine car 1 is in use, it forms a hopper structure with two semi-V-shaped inner hoppers 201. The ore is placed directly inside the hopper structure, so that the ore does not directly impact the car body 101, effectively avoiding the deformation and damage of the car body 101 by impact. When the two semi-V-shaped inner buckets 201 are damaged after a period of use, the fastening bolts 205 can be removed with tools. Then, the car body 101 is tilted and tilted. At this time, the semi-V-shaped inner buckets 201, concave folded edges 202, and connecting arms 203 will slide down and fall off under their own weight, thus realizing the disassembly of the semi-V-shaped inner buckets 201. After that, a new set of semi-V-shaped inner buckets 201, concave folded edges 202, and connecting arms 203 can be installed. The operation is simple and convenient. (It should be noted that when disassembling the semi-V-shaped inner buckets 201, ramps can be set on both sides of the tipper mine car 1 track to provide sufficient space for the semi-V-shaped inner buckets 201 to slide down.)
[0017] Please refer to this carefully. Figures 1-2 Multiple sets of connecting arms 203 and concave fixing sleeves 204 are evenly arranged along the long side of the concave folded edge 202. Each set of connecting arms 203 and concave fixing sleeves 204 is connected and fixed by multiple fastening bolts 205.
[0018] In this embodiment, the structure of multiple connecting arms 203, concave fixing sleeves 204 and multiple fastening bolts 205 provides sufficient connection force for the installation of the semi-V-shaped inner hopper 201, ensuring the stable use of the semi-V-shaped inner hopper 201.
[0019] Please refer to this carefully. Figures 2-3 Multiple longitudinally distributed vertical reinforcing ribs 3 are symmetrically welded and fixed at both ends of the inner wall of the carriage 101. The bottom of the vertical reinforcing ribs 3 is welded and fixed to the semi-circular bottom and side of the carriage 101. Multiple horizontally distributed V-shaped reinforcing ribs 4 are welded and fixed to the bottom and sides of the semi-circular arc of the carriage 101. The inner surface of the V-shaped reinforcing ribs 4 is in contact with the outer surface of the semi-V-shaped inner hopper 201. The vertical reinforcing rib 3 is in contact with the end face of the semi-V-shaped inner hopper 201, and the center line of the vertical reinforcing rib 3 distributed in the middle is aligned with the splicing surface of the two semi-V-shaped inner hoppers 201. The lower surface of the concave fold 202 is in contact with the top of the carriage 101, the vertical reinforcing rib 3, and the V-shaped reinforcing rib 4, and the outer wall dimension of the concave fold 202 is larger than the outer wall dimension of the carriage 101.
[0020] In this embodiment: the vertical stiffener 3 can provide welded reinforcement between the end plate and the side plate of the carriage 101 and the bottom of the semi-circular arc, so as to avoid cracking at the welded semi-circular arc at both ends of the carriage 101; the V-shaped stiffener 4 can improve the deformation resistance of the side plate and the bottom of the semi-circular arc of the carriage 101. In addition, the V-shaped reinforcing ribs 4 and vertical reinforcing ribs 3 can provide support for the two semi-V-shaped inner hoppers 201, thereby improving the deformation resistance of the semi-V-shaped inner hoppers 201. The concave fold 202 not only provides a connection between the semi-V-shaped inner hopper 201 and the connecting arm 203, but also seals the gap between the semi-V-shaped inner hopper 201 and the carriage 101, preventing ore from falling into the gap between the semi-V-shaped inner hopper 201 and the carriage 101.
[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
