Description

Technical Field

[0001] This utility model relates to the field of coal mine transportation equipment, and more specifically, to a multi-functional mining car. Background Technology

[0002] Coal mines are areas where humans extract coal resources in coal-rich areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, tunnels are usually dug underground to mine the coal. This is called an underground coal mine. In coal mining, mine cars are an indispensable tool.

[0003] Currently, during the process of transporting coal in mining trucks, the truck beds are directly connected to the outside environment, resulting in a large amount of coal dust spilling out and causing environmental pollution. The lack of dust suppression function, coupled with the fact that most current mining trucks do not have the function of convenient tipping and unloading, means that the effectiveness and functionality of mining trucks need to be improved.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0038] like Figures 1 to 3 As shown, a multi-functional mining car includes a frame 1, wheels 2 mounted on the frame 1, and side bars symmetrically fixed on the frame 1. It also includes a U-shaped car body 3, connecting rollers 4, through holes, a limiting assembly 5, a cover plate 6, a mounting assembly 7, limiting rods 8, a receiving groove 9, a dust-adhesive assembly 10, and a buffer component 11 (specifically, a polyurethane buffer).

[0039] The U-shaped carriage 3 is symmetrically welded with connecting rollers 4 that are rotatably connected to the side rods, and one of the connecting rollers 4 has a through hole (the through hole is not shown in the figure);

[0040] The limiting component 5 cooperates with the through hole to keep the U-shaped carriage 3 in a vertical position;

[0041] The cover plate 6 is connected to the U-shaped carriage 3 and seals its upper surface through the mounting assembly 7 set on the U-shaped carriage 3, and the cover plate 6 abuts against the limiting rod 8 fixed on the U-shaped carriage 3;

[0042] The receiving groove 9 is opened inside the cover plate 6, and the dust-adhesive component 10 is provided inside the receiving groove 9;

[0043] Two buffer components 11 are symmetrically arranged on the outer sides of the two side rods.

[0044] Specific implementations of the embodiments of this utility model, such as Figure 1 As shown, the limiting assembly 5 includes a cylinder 51, a roller 52, an external thread, and an internal thread (the external thread and internal thread are not shown in the figure).

[0045] The insert 51 is welded onto the frame 1;

[0046] The insertion roller 52 passes through the through hole and engages with the insertion cylinder 51 to keep the U-shaped carriage 3 in a vertical position;

[0047] The external thread is provided at one end of the insertion roller 52 that is inserted into the insertion cylinder 51;

[0048] The bottom area of ​​the insert 51 is provided with an internal thread that matches the external thread. The purpose of the threaded connection between the bottom of the insert 51 and one end of the insert roller 52 is to prevent the insert roller 52 from fluctuating up and down when the mine car is bumpy, thus causing the U-shaped car 3 to have an unstable limiting effect.

[0049] As shown in the figure, the specific implementation of this utility model embodiment includes an installation rod 71, a plug rod 72, an L-shaped connecting rod 73, and a slot 74.

[0050] Mounting rods 71 ​​are symmetrically welded onto the U-shaped carriage 3 and are flush with the top of the U-shaped carriage 3;

[0051] The insertion rod 72 is symmetrically welded to the cover plate 6 via the L-shaped connecting rod 73;

[0052] A slot 74, which is adapted to the shape of the insertion rod 72 and corresponds to it one by one, is opened on the mounting rod 71, and the insertion rod 72 and the slot 74 cooperate.

[0053] To ensure the cover plate 6 is stable after installation, further optimizations to the above-described embodiments are made, such as... Figure 1 As shown, a handle 13 is provided on the cover plate 6, and a magnet is provided at the end of the slot 74. The insertion rod 72 is made of martensitic stainless steel.

[0054] As shown in the figure, the specific implementation of this utility model embodiment includes a dust-adhesive assembly 10, a mounting frame 101, mounting holes 102, a dust-adhesive mesh 103, and fixing bolts 104.

[0055] The outer wall of the mounting frame 101 is circumferentially fitted to the inner wall of the receiving groove 9, and mounting holes 102 are symmetrically opened on the mounting frame 101;

[0056] The dust-adhesive screen 103 is mounted on the mounting frame 101;

[0057] The fixing bolt 104 passes through the mounting hole 102 and is threaded into the threaded hole on the cover plate 6 (the threaded hole on the cover plate 6 is not shown in the figure).

[0058] To avoid hard contact between the U-shaped carriage 3 and the frame 1 during unloading, further optimizations to the above embodiments are made, such as... Figure 1 As shown, the frame 1 is provided with a rubber strip 12 that flexibly contacts the U-shaped carriage 3.

[0059] To effectively reduce the amount of wet material adhering to the inner wall of the U-shaped carriage 3, the above-described embodiment is further optimized by coating the inner wall of the U-shaped carriage 3 with epoxy primer, and then coating the outer side of the epoxy primer with a nano-composite coating. First, a 50-80μm epoxy primer is sprayed to ensure adhesion, and then a 20-30μm nano-composite coating is superimposed to achieve surface functionalization. The surface structure of the nano-composite coating can effectively block the adhesion of wet material, reducing the amount of residue by more than 60%.

[0060] The working process of this utility model:

[0061] Initially, the orientation of the U-shaped carriage 3 is limited by the limiting component 5 in conjunction with the through hole (i.e., the U-shaped carriage 3 is in a vertical state under the action of the limiting component 5), so that the U-shaped carriage 3 will not experience large positional shaking during material unloading and subsequent transfer. Then, the coal is placed into the U-shaped carriage 3. After the coal is placed, the cover plate 6 is installed by the installation component 7. The installation component 7 can accurately align with the cover plate 6, and after alignment, the bottom surface of the cover plate 6 fits against the top surface of the U-shaped carriage 3. At this time, the amount of dust overflow during subsequent coal transportation can be effectively reduced, and the cover plate 6 does not come into contact with the coal during installation.

[0062] At the same time, a dust-adhesive component 10 is installed on the inner side of the cover plate 6 to further capture coal dust particles raised during transportation, with a dust suppression efficiency of 60-80%.

[0063] Once the coal mine reaches the unloading area, the limit on the U-shaped car 3 can be released and manually intervened to achieve the directional tilting of the U-shaped car 3. Then the coal can be unloaded to the designated mining area for subsequent processing. It should be noted that the coal storage area is lower than the ground height of the track of the mine car wheel 2. After unloading is completed, the U-shaped car 3 can be reset.

[0064] During the movement of the mine car, the polyurethane buffers on both sides can prevent the front or rear of the car from being damaged by a violent collision, thus achieving a safety protection effect.

[0065] In summary, the mining truck in this application has multiple functions such as tipping unloading, dust suppression, and safety protection, thus making the mining truck more effective.

[0066] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
