Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for mining trucks, specifically a device to prevent mining trucks from running away. Background Technology

[0002] Mining cars are narrow-gauge railway 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) discharge mining cars, and shuttle mining cars.

[0003] Mining cars are vehicles pulled by locomotives or winches to transport coal, gangue, equipment, and personnel. They are mainly used for rail transport in underground mine roadways, shafts, and on the surface. They are the most widely used and numerous type of transport equipment in coal mines, with common track gauges of 600, 762, and 900 mm.

[0004] In existing technologies, the intake shaft serves as the primary point for material entry and exit, responsible for the normal material intake of various teams. During daily transportation, mine cars often need to stop at specific locations, such as loading points, unloading points, or maintenance areas. However, due to factors such as track gradient or improper operation, mine cars sometimes slip when stationary. This not only damages transportation equipment but can also lead to safety accidents, posing a serious threat to personnel and property. The lack of effective measures to prevent runaway mine cars presents certain safety hazards. Utility Model Content

[0018] 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.

[0019] Please see Figures 1-3 This utility model discloses a mine car anti-runaway device, including a frame 1. A wheel assembly 2 is provided on the lower surface of the frame 1. Mounting mechanisms 3 are provided on the upper and lower inner walls of the frame 1 near the left and right sides. A drive mechanism 4 is fixedly mounted on each of the left and right mounting mechanisms 3. The drive mechanism 4 is fixedly connected to the input shaft of a reducer 5. A connecting plate 6 is fixedly mounted on the front side of the output shaft of the reducer 5. A blocking mechanism 8 is mounted on the connecting plate 6 through a rotating mechanism 7. A guide mechanism 9 is provided on the rear side of the blocking mechanism 8. The guide mechanism 9 is installed on the left side of a vertical plate 10. The right side of the reducer 5 is fixedly mounted near the front side of the vertical plate 10.

[0020] Specifically, the mounting mechanism 3 includes a mounting plate 301 and mounting holes 302. There are two mounting plates 301 arranged vertically, and the mounting plates 301 have rectangular mounting holes 302 at their four corners.

[0021] In this embodiment, the mounting hole 302 on the mounting plate 301 mates with the reserved hole on the frame 1, and the mounting plate 301 is easily fixed to the frame 1 by bolts.

[0022] Specifically, the drive mechanism 4 includes a bearing assembly 401, a first sleeve 402, a handle 403, a locking bolt 404, and a second sleeve 405. The bearing assembly 401 is fixedly installed between the upper and lower mounting plates 301. The first sleeve 402 is installed inside the bearing assembly 401. The handle 403 is fixedly installed on the end of the first sleeve 402 away from the reducer 5. The second sleeve 405 is installed on the end of the first sleeve 402 facing the reducer 5 by the locking bolt 404, and the second sleeve 405 is movably inserted into the first sleeve 402. The second sleeve 405 is fixedly connected to the input shaft of the reducer 5.

[0023] In this embodiment, the handle 403 drives the first sleeve 402 to rotate in the bearing assembly 401, which in turn drives the second sleeve 405 to rotate. The second sleeve 405 drives the input shaft of the reducer 5 to rotate, and the locking bolt 404 is tightened or loosened, so that the second sleeve 405 can move within the first sleeve 402, thereby achieving the effect of adjusting the overall length of the drive mechanism 4.

[0024] Specifically, the rotating mechanism 7 includes a pin 701, a first bushing 702, and a first limiting pin 703. The pin 701 is fixedly installed on the front side of the connecting plate 6 near the lower edge. The first bushing 702 is movably sleeved on the pin 701, and the first limiting pin 703 is inserted into the pin 701 on the front side of the first bushing 702.

[0025] In this embodiment, the first limiting pin 703 limits the first bushing 702 to the fish pin shaft 701, so that the first bushing 702 has a rotation function.

[0026] Specifically, the blocking mechanism 8 includes a transmission rod 801 and a blocking block 802. The transmission rod 801 is fixedly installed on the left side of the first bushing 702, and the blocking block 802 is fixedly installed on the left side of the transmission rod 801, and the blocking block 802 is inserted into the lower side of the wheel assembly 2.

[0027] In this embodiment, the transmission rod 801 moves with the first bushing 702, causing the transmission rod 801 to drive the blocking block 802 to be inserted into the lower side of the wheel assembly 2, thus blocking the wheel assembly 2.

[0028] Specifically, the guiding mechanism 9 includes a guide sleeve 901, a rotating shaft 902, a second bushing 903, and a second limiting pin 904. The guide sleeve 901 is movably sleeved on the transmission rod 801. The rotating shaft 902 is fixedly installed on the rear side of the guide sleeve 901, and the second bushing 903 is movably sleeved on the rotating shaft 902. The second bushing 903 is fixedly installed on the left side of the vertical plate 10, and the second limiting pin 904 is inserted into the second bushing 903 near the rear side.

[0029] In this embodiment, the second limiting pin 904 limits the rotating shaft 902 within the second bushing 903, enabling the rotating shaft 902 to rotate, which in turn enables the guide sleeve 901 to rotate, thereby guiding the left and right movement of the transmission rod 801.

[0030] In use, according to the length of the frame 1, the locking bolts 404 in the drive mechanism 4 are tightened or loosened, allowing the second sleeve 405 to move within the first sleeve 402, thus adjusting the overall length of the drive mechanism 4 and positioning the reducer 5 on the frame 1. Then, the mounting holes 302 on the mounting plate 301 in the mounting mechanism 3 are aligned with the pre-drilled holes on the frame 1, and bolts are used to install the plate 301 into the mounting holes 302, thus fixing the mounting plate 301 to the frame 1. The first sleeve 402 and the second sleeve 405 are then locked together using the front and rear locking bolts 404. Finally, the handle 403 rotates the first sleeve 402 within the bearing assembly 401, causing the first sleeve 402 to rotate the second sleeve 405, which in turn rotates the reducer 5. When the shaft rotates, the output shaft of the reducer 5 drives the connecting plate 6 to rotate. The connecting plate 6 drives the first bushing 702 to move to the left via the pin 701. This causes the first bushing 702 to drive the transmission rod 801 in the blocking mechanism 8 to move to the left. The second limit pin 904 in the guide mechanism 9 limits the rotating shaft 902 to the second bushing 903, giving the rotating shaft 902 a rotation function, which in turn gives the guide sleeve 901 a rotation function. This allows the guide sleeve 901 to guide the left and right movement of the transmission rod 801. The transmission rod 801 drives the blocking block 802 to be inserted into the lower surface of the wheel assembly 2, preventing the wheel assembly 2 from rotating and achieving anti-slippage. The device has a compact structure, small size, and light weight, and will not have too much impact on the normal operation of the mine car or the layout of other equipment.

[0031] In summary, this mine car anti-runaway device is easy to install on mine cars of different specifications, preventing the wheel assembly 2 from rotating and thus preventing the car from running away. The device has a compact structure, small size, and light weight, and will not have too much impact on the normal operation of the mine car or the layout of other equipment.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
