Description

Technical Field

[0001] The utility model relates to the field of coal transportation, and more specifically, to an underground coal transportation device. Background Art

[0002] Coal is the most abundant and widely distributed fossil fuel on earth. The elements that make up the organic matter of coal are mainly carbon, hydrogen, oxygen, nitrogen and sulfur. In addition, there are very small amounts of phosphorus, fluorine, chlorine and arsenic. Coal resources are also very important resources. Coal resources can provide a steady stream of energy and play a vital role in people's production and life. Nowadays, many coal resources are buried in underground mines and need to wait for people to mine. After mining coal, workers need to use transportation equipment to transport coal resources out.

[0003] The Chinese patent authorization announcement number: CN213869954U provides an improved coal underground transportation device. This patent installs a coal scraping mechanism in the device. When taking coal, the coal scraping mechanism can be driven to rotate, which can effectively scrape the coal in the coal storage trough to prevent coal from remaining on the inner wall of the coal storage trough. At the same time, an automatically retractable cleaning brush is installed on the side wall of the coal scraping mechanism. After each scraping, the cleaning brush can be cleaned again at the same time to ensure the thoroughness and effectiveness of scraping and cleaning.

[0004] In the existing technology, underground coal is transported by special transport vehicles moving on tracks. However, when the coal mine is full, it will fall from the transport vehicle during transportation, which increases the cost of coal mining and easily blocks the transport vehicle track, thereby affecting the use of the transport vehicle. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] In view of the problems existing in the prior art, the purpose of the utility model is to provide a coal underground transportation device, which can realize the coal being poured into the interior of the transport vehicle by arranging a limit frame on the upper end of the outer side of the transport vehicle and installing a support sealing plate supported by springs at the bottom of the transport vehicle. The gravity of the coal will press the support sealing plate downward, and under the action of the linkage assembly, the limit frame will be synchronously driven to move upward, thereby increasing the overall height of the transport vehicle, reducing coal leakage, reducing coal mining costs, and avoiding interference with the transport vehicle track.

[0007] 2. Technical solution

[0008] To solve the above problems, the utility model adopts the following technical solutions.

[0009] A coal underground transportation device includes a transport vehicle, a plurality of springs are fixedly installed on the bottom of the transport vehicle, a support sealing plate is fixedly installed on the upper end of the springs, the support sealing plate is installed inside the transport vehicle by a sliding connection, the support sealing plate is adapted to the internal shape of the transport vehicle, a limit frame is slidably installed on the upper end of the outer side of the transport vehicle, support rods are fixedly installed on both sides of the lower end of the limit frame, limit holes are provided on the lower ends of both sides of the transport vehicle, a linkage assembly is installed inside the limit hole, and the linkage assembly is rotatably connected to the support rod and the support sealing plate.

[0010] Furthermore, two limiting slide grooves are arranged on both sides of the transport vehicle, and rollers are rotatably installed at the front and rear ends of both sides of the supporting sealing plate, and the rollers are movably clamped in the limiting slide grooves.

[0011] Furthermore, universal wheels are fixedly installed at the four corners of the lower end of the transport vehicle, and coal is arranged inside the transport vehicle, and the coal is located at the upper end of the supporting sealing plate.

[0012] Furthermore, the two linkage components each include a fixed seat and a rocker arm. The fixed seat is installed at both ends of the bottom of the transport vehicle by a fixed connection method, and the rocker arm is installed at the front end of the fixed seat by a rotational connection method. The rocker arm is rotationally connected to the support sealing plate and the support rod, and the rocker arm passes through the inside of the limiting hole.

[0013] Furthermore, the two rocker arms each include a movable sleeve and two movable connecting rods, the movable connecting rods are installed on both sides of the movable sleeve by a movable insertion method, the movable sleeve is installed at the front end of the fixed seat by a rotational connection method, and the end of the movable connecting rod away from the movable sleeve is rotationally connected to the support sealing plate and the support rod.

[0014] 3. Beneficial effects

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] (1) This solution can be realized by installing a limit frame on the upper end of the outer side of the transport vehicle and installing a support sealing plate supported by a spring at the bottom of the transport vehicle. When coal is poured into the interior of the transport vehicle, the gravity of the coal will press the support sealing plate downward. Under the action of the linkage assembly, the limit frame is synchronously driven to move upward, thereby increasing the overall height of the transport vehicle, reducing coal leakage, reducing coal mining costs, and avoiding interference with the transport vehicle track.

[0017] (2) The support sealing plate can be limited by setting the limiting slide groove and the rollers. The rollers on both sides of the support sealing plate can slide up and down in the limiting slide groove, which is convenient for the lifting and lowering movement and limiting of the support sealing plate, thereby improving the stability of the support sealing plate.

[0018] (3) The support sealing plate and the support rod are connected at both ends of the rocker respectively. The support sealing plate will move up and down when materials are placed inside the transport vehicle or when it is reset by default. At the same time, through the setting of the linkage component, the support rod and the limit frame move in the same direction as the support sealing plate. When materials are placed inside the transport vehicle, the support sealing plate moves downward due to the influence of gravity, and the limit frame moves upward, thereby increasing the height of the transport vehicle and reducing material leakage. When the materials are taken out, the support sealing plate moves upward and resets under the automatic extension of the spring, and the limit frame moves downward and resets.

[0019] (4) Since the supporting sealing plate and the supporting rod move vertically up and down, and the two ends of the swing arm are connected to the supporting sealing plate and the supporting rod, the movable connecting rod and the movable sleeve are combined to enable the movable connecting rod to be retractable and movable in the movable sleeve when the swing arm swings.

In the default state, the spring 3 is stretched, and the support sealing plate 4 is located in the middle position of the transport vehicle 1 under the support of the spring 3.

[0030] Two limiting slide grooves 101 are arranged on both sides of the transport vehicle 1, and rollers 41 are rotatably installed on the front and rear ends of both sides of the supporting sealing plate 4, and the rollers 41 are movably clamped in the limiting slide grooves 101. When in use, the supporting sealing plate 4 can be limited by the setting of the limiting slide grooves 101 and the rollers 41, and the rollers 41 on both sides of the supporting sealing plate 4 can slide up and down in the limiting slide grooves 101, which is convenient for the lifting and lowering movement and limiting of the supporting sealing plate 4, and improves the stability of the supporting sealing plate 4.

[0031] Universal wheels 2 are fixedly installed at the four corners of the lower end of the transport vehicle 1. When in use, the transport vehicle 1 can move in multiple directions through the installation of the universal wheels 2.

[0032] The two linkage components 6 each include a fixed seat 61 and a rocker arm 62. The fixed seat 61 is installed at both ends of the bottom of the transport vehicle 1 by a fixed connection, and the rocker arm 62 is installed at the front end of the fixed seat 61 by a rotational connection. The rocker arm 62 is rotationally connected to the support sealing plate 4 and the support rod 51, and the rocker arm 62 passes through the inside of the limiting hole 102. When in use, the support sealing plate 4 and the support rod 51 are respectively connected through the two ends of the rocker arm 62. The support sealing plate 4 will move up and down when the transport vehicle 1 contains materials or is reset by default. At the same time, through the setting of the linkage component 6, the support rod 51 and the limit frame 5 move in the same direction as the support sealing plate 4.
