Description

Technical Field

[0001] This utility model relates to the field of coal mining technology, specifically an anti-tipping mechanism for coal mine transportation. Background Technology

[0002] Coal mines are areas where humans extract coal resources in coal-rich areas, generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, underground tunnels are typically dug to extract the coal; this is called an underground coal mine. When the coal seam is very close to the surface, the surface soil is typically stripped away to extract the coal; this is called an open-pit coal mine. The vast majority of coal mines in China are underground mines, typically including tunnels, shafts, and working faces.

[0003] Utility model patent CN218316851U discloses a coal mine transport vehicle, relating to the field of transport vehicle technology. Specifically, it is a coal mine transport vehicle including a floor, with a carriage fixedly connected to the upper surface of the floor. This coal mine transport vehicle, through a drive assembly, an opening and closing assembly, and a scraping assembly, activates a cylinder during coal transport. One end of the cylinder then extends and retracts, pushing against cover plate A, thereby adjusting the tilt angle of cover plate A. When cover plate A adjusts its tilt angle, a connecting rod drives the adjustment of the tilt angle of cover plate B, thus causing cover plates A and B to cover the carriage, thereby reducing the amount of coal falling during transport.

[0004] When excavating coal in underground mines, railcars are used to transport coal. Although the transport vehicle in the aforementioned patent prevents coal from falling into the mine, when the fully loaded vehicle turns, it may overturn due to its high center of gravity and large inertia, increasing the risk of coal transportation. To address this issue, we provide an anti-overturning mechanism for coal transportation. Utility Model Content

[0005] The purpose of this invention is to provide an anti-tipping mechanism for coal mine transportation to solve the problems raised in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-rollover mechanism for coal mine transportation, comprising a vehicle base and a fixing plate, wherein a T-shaped frame is fixedly connected to the surface of the fixing plate, and an equidistantly arranged mounting mechanism is provided at the bottom of the fixing plate, the mounting mechanism comprising a mounting frame and a support rod, and the mounting frame being fixedly connected to the fixing plate; positioning mechanisms are provided at the four corners of the vehicle base, each positioning mechanism comprising a mounting plate, a support shaft being rotatably connected to the center of the mounting plate, a support frame being fixedly connected to the bottom of the support shaft, and positioning rollers being rotatably connected inside the support frame, and the positioning rollers being movably connected to the T-shaped frame.

[0007] Preferably, the surface of the fixing plate is fixedly connected with equidistantly arranged ground anchors, and the bottom end of the ground anchors is inserted into the track foundation. The mounting plate is fixedly connected to the vehicle base by bolts. The ground anchors provide secondary reinforcement to the fixing plate and enhance its gripping ability.

[0008] Preferably, the support rod abuts against the bottom surface of the track, and both ends of the support rod are fixedly connected to side fixing rods, which are interlocked with the two tracks. By having the fixing rods abut against the tracks on both sides, the support rod is fixed to the bottom of the two tracks, preventing the support rod from sliding laterally under the action of external force.

[0009] Preferably, the support rod is snapped into the mounting frame, and a reinforcing buckle is fixedly connected to the middle of the support rod. The reinforcing buckle is snapped into the mounting frame. The connection between the support rod and the mounting frame is clamped and fixed by the reinforcing buckle. The mutual snapping with the mounting frame improves the fixing ability of the mounting frame for the support rod.

[0010] Preferably, the middle of the fixing plate is movably connected with a mounting bolt, and the bottom end of the mounting bolt passes through the mounting frame and is threadedly connected to the support rod. The support rod is fixed inside the mounting frame by the mounting bolt, which improves the convenience of fixing and installing the support rod.

[0011] Preferably, a sliding rod is rotatably connected to the surface of the support shaft, and a support sleeve is slidably connected to the surface of the sliding rod. The support sleeve is rotatably connected to the mounting plate, and the sliding rod is fixed by the support sleeve, so that the support shaft is kept relatively parallel to the track.

[0012] Preferably, the fixed shaft of the positioning roller is rotatably connected to a rotating ball, and the rotating ball is slidably connected to the T-shaped frame. The support sleeve is fixedly connected to a telescopic spring, and the other end of the telescopic spring is fixedly connected to a sliding rod. By rotating the ball, the friction between the positioning roller and the T-shaped frame is reduced, and the stability of the positioning roller sliding on the surface of the T-shaped frame is improved.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This application uses the support rods on both sides to abut against the bottom of the two rails, fixing the fixing plate to the surface of the rail sleepers, and then fixing the device on the rails. When the center of gravity of the vehicle changes, the positioning rollers slide to the top wall of the T-shaped frame to fix the vehicle base, preventing the vehicle base from leaving the rails, reducing the probability of the transport vehicle overturning, and improving the stability of the transport vehicle in transporting coal.

[0015] 2. This application reinforces the fixing plate by fixing ground anchors, enhancing its grip and providing a more stable pulling force to the vehicle base. By installing bolts, the support rod is fixed inside the mounting frame, improving the convenience of fixing and installing the anti-rollover mechanism. By rotating the ball bearings, the friction between the positioning roller and the T-frame is reduced, improving the stability of the positioning roller sliding on the surface of the T-frame, thereby improving the positioning ability of the T-frame to the vehicle base.

[0021] 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.

[0022] like Figure 1 - Figure 4 As shown, this utility model provides a technical solution for an anti-rollover mechanism for coal mine transportation, including a vehicle base 1 and a fixing plate 2. A T-shaped frame 3 is fixedly connected to the surface of the fixing plate 2, and the T-shaped frame 3 is fixedly installed through the fixing plate 2.

[0023] The surface of the fixing plate 2 is fixedly connected with equidistantly arranged fixed ground anchors 4, and the bottom end of the fixed ground anchors 4 is inserted into the track foundation. The fixed plate 2 is reinforced secondary by the fixed ground anchors 4, which enhances the gripping ability of the fixing plate 2 and makes the fixing plate 2 provide a more stable pulling force to the vehicle base 1.

[0024] like Figure 2 As shown, the bottom of the fixing plate 2 is provided with an equidistantly arranged installation mechanism 5. The installation mechanism 5 includes a mounting frame 501 and a support rod 502. The mounting frame 501 is fixedly connected to the fixing plate 2. The support rod 502 is positioned by the mounting frame 501. The fixing plate 2 is fixed to the surface of the track sleepers by the two sides of the support rod 502 abutting against the bottom of the two tracks, thereby fixing the device on the track and reducing the difficulty of device installation.

[0025] The support rod 502 abuts against the bottom surface of the track. Both ends of the support rod 502 are fixedly connected to side fixing rods 503, and the side fixing rods 503 are interlocked with the two tracks. By the side fixing rods 503 abutting against the tracks on both sides, the support rod 502 is fixed to the bottom of the two tracks, preventing the support rod 502 from sliding laterally under the action of external force and improving the fixing ability of the support rod 502 to the fixing plate 2.

[0026] The support rod 502 is snapped into the mounting bracket 501. A reinforcing buckle 504 is fixedly connected to the middle of the support rod 502, and the reinforcing buckle 504 is snapped into the mounting bracket 501. The reinforcing buckle 504 clamps and fixes the connection between the support rod 502 and the mounting bracket 501. The mutual snapping with the mounting bracket 501 improves the fixing ability of the mounting bracket 501 to the support rod 502.

[0027] The middle part of the fixing plate 2 is movably connected with a mounting bolt 505, and the bottom end of the mounting bolt 505 passes through the mounting bracket 501 and is threadedly connected to the support rod 502. The support rod 502 is fixed inside the mounting bracket 501 by the mounting bolt 505, which improves the convenience of fixing and installing the support rod 502.

[0028] like Figure 3 and Figure 4 As shown, positioning mechanisms 6 are provided at the four corners of the vehicle base 1. The positioning mechanism 6 includes a mounting plate 601, which is fixedly connected to the vehicle base 1 by bolts. A support shaft 602 is rotatably connected to the middle of the mounting plate 601. A support frame 603 is fixedly connected to the bottom of the support shaft 602. A positioning roller 604 is rotatably connected inside the support frame 603, and the positioning roller 604 is movably connected to the T-shaped frame 3.

[0029] The mounting plate 601 is assembled with the vehicle base 1, thereby fixing the positioning mechanism 6 to the bottom of the vehicle base 1. The support frame 603 is fixedly installed with the mounting plate 601 via the support shaft 602. When the transport vehicle turns, the support frame 603 can rotate within a certain range. When the vehicle's center of gravity changes, the positioning roller 604 slides and connects with the inner top wall of the T-shaped frame 3 to fix the vehicle base 1, preventing the vehicle base 1 from derailing, reducing the probability of the transport vehicle overturning, and improving the stability of the transport vehicle in transporting coal.

[0030] A sliding rod 607 is rotatably connected to the surface of the support shaft 602, and a support sleeve 606 is slidably connected to the surface of the sliding rod 607. The support sleeve 606 is rotatably connected to the mounting plate 601. A telescopic spring 608 is fixedly connected inside the support sleeve 606, and the other end of the telescopic spring 608 is fixedly connected to the sliding rod 607. The sliding rod 607 is fixed by the support sleeve 606, and the telescopic spring 608 provides thrust to the sliding rod 607. Through the interaction of the two sliding rods 607, the support shaft 602 is kept relatively parallel to the track, which improves the stability of the support frame 603 during operation.

[0031] The fixed shaft of the positioning roller 604 is rotatably connected to a rotating ball 605, and the rotating ball 605 is slidably connected to the T-shaped frame 3. By rotating the ball 605, the friction between the positioning roller 604 and the T-shaped frame 3 is reduced, the stability of the positioning roller 604 sliding on the surface of the T-shaped frame 3 is improved, and the positioning ability of the T-shaped frame 3 on the vehicle base 1 is improved.

[0032] In use, this utility model first fixes four mounting plates 601 to the bottom of the vehicle base 1 with bolts. According to the position of the mounting plates 601, the fixing anchor 4 is inserted into the foundation to initially fix and position the fixing plate 2. Then, the support rod 502 is inserted under the track and the support rod 502 is interlocked with the mounting frame 501. The connection between the support rod 502 and the mounting frame 501 is reinforced by the reinforcing buckle plate 504. The support rod 502 is fixed inside the mounting frame 501 by the mounting bolts 505. Before the transport vehicle needs to turn, the positioning roller 604 and the rotating ball 605 first contact the surface of the T-shaped frame 3 to fix the support frame 603 to the surface of the T-shaped frame 3, thereby reinforcing both sides of the vehicle base 1. When the center of gravity of the vehicle changes, the positioning roller 604 slides to the inner top wall of the T-shaped frame 3 to fix the vehicle base 1, preventing the vehicle base 1 from derailing from the track, reducing the probability of the transport vehicle overturning, and improving the stability of the transport vehicle in transporting coal.
