Description

Technical Field

[0001] This invention relates to the field of mining machinery technology, specifically to a mining rail transport vehicle. Background Technology

[0002] A mine refers to an independent production and operation unit that extracts ore within a certain mining boundary. A mine mainly includes one or more mining workshops (also known as pitheads, mine shafts, open-pit mines, etc.) and some auxiliary workshops. Most mines also include ore dressing plants (coal washing plants). Mines include coal mines, metal mines, non-metal mines, building material mines, and chemical mines, etc.

[0003] However, existing mining machinery and equipment have poor shock absorption and buffering capabilities, and are prone to large collisions during use, which reduces the service life of the equipment. The shock absorption equipment occupies a large space, cannot optimize the air quality during mining construction, and cannot effectively prevent secondary pollution caused by the rising of dust in the air. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a mine rail transport vehicle that solves the problem of poor shock absorption and buffering capacity of existing mining machinery and equipment. It reduces the degree of collision generated during the use of mining machinery and equipment, improves the service life of the device, reduces the space occupied by the shock absorption equipment, optimizes air quality during mine construction, and effectively prevents secondary pollution caused by the stirring up of dust in the air.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a mine rail transport vehicle, comprising a transport frame, wherein rollers are symmetrically mounted on the bottom of the transport frame, and the interior of the transport frame is provided with:

[0008] An air extraction device includes air extraction columns symmetrically installed on the inner bottom of the transport frame. Each air extraction column has an internal air extraction groove and symmetrical air extraction holes at its top, communicating with the air extraction groove. One end of the bottom of the air extraction groove extends through the air extraction column. A lifting plate is slidably connected between the two sides of the inner wall of the transport frame, extending into the air extraction groove. A sealing folding plate is slidably connected between the two sides of the inner wall of the air extraction groove, with its bottom fixedly connected to the lifting plate. During the descent of the lifting plate... The space inside the extraction trough above the lifting plate gradually increases, and the air pressure inside the extraction trough above the lifting plate decreases. This draws the air around the extraction column into the extraction trough through the extraction hole. Dust particles generated around the transport frame due to ore handling enter the extraction trough with the air and settle inside. As the lifting plate is pushed upward by the buffer spring and elastic plate, the air inside the extraction trough is discharged through the extraction hole, which improves the air purification capacity of the device and can remove dust generated by ore handling from the air, thus optimizing the working environment in mine construction.

[0009] A buffer device is provided, which has a limiting post. The top end of the limiting post is fixedly connected to the lifting plate. The bottom of the limiting post passes through the transport frame and extends to the outside of the transport frame. A buffer spring is sleeved on the outside of the limiting post. An elastic plate is fixedly connected to the bottom of the lifting plate.

[0010] Preferably, the limiting post has an upper post and a lower post, which are alternately connected. A limiting groove is formed at the bottom of both the upper post and the lower post, and a limiting block is fixedly connected to the end of the upper post and the lower post away from the limiting groove.

[0011] Preferably, a limiting frame is fixedly connected to the inner bottom of the transport frame, and one bottom end of the elastic plate extends into the interior of the limiting frame and is slidably connected to the limiting frame. When the ore presses down on the lifting plate, the lifting plate presses the limiting post down to the outside of the transport frame, which in turn presses and bends the buffer spring and the elastic plate. As the amount of ore inside the transport frame gradually increases, the bending range of the buffer spring and the elastic plate gradually increases, and the tilt angle between the bottom of the elastic plate and the bottom of the transport frame gradually decreases. Finally, one bottom end of the elastic plate slides to the outside of the limiting frame and is close to horizontal with the bottom of the transport frame, which improves the buffering capacity of the mining transport equipment, reduces the space occupied by the buffer structure, and improves the transport capacity of the mining transport equipment.

[0012] Preferably, the outer side of the transport frame is symmetrically provided with discharge grooves, the discharge grooves pass through the transport frame and the air extraction column and are connected to the air extraction groove, and the two sides of the transport frame are fixedly connected to receiving frames below the discharge grooves.

[0013] Preferably, a magnet is installed on one side of the receiving frame, and the limiting post is made of magnetic metal. After the limiting post is pressed down by the lifting plate to the outside of the transport frame, it is attracted by the magnet. After the upper and lower posts are completely lowered to the outside of the transport frame, they are attracted by the magnet and hit the receiving frame, and finally adhere to the receiving frame. The sound generated by the impact can be used to alarm the ore loading amount. After the limiting post hits the receiving frame several times and produces a sound, loading stops and transport is carried out, which improves the intelligence level of the device.

[0014] Preferably, a longitudinal column is fixedly connected to the top of the lifting plate inside the air extraction groove, and a dust baffle is fixedly connected to the top of the longitudinal column. Air around the transport frame enters the air extraction groove through the air extraction hole, and dust in the air settles below the dust baffle. When the buffer spring and elastic plate push the lifting plate upward, the air inside the air extraction groove is pushed out through the air extraction hole. When the dust inside the air extraction groove is moved upward by the air, it is blocked by the dust baffle, which can effectively fix the filtered dust in the air and prevent the dust from re-entering the air and causing secondary pollution to the air environment of the mine construction.

[0015] Preferably, an elastic rope is fixedly connected to the bottom of the dust baffle, and an impact ball is fixedly connected to the end of the elastic rope away from the dust baffle. As the lifting plate rises, the elastic rope is stretched. When the lifting plate rises to its highest point, the air inside the suction trough stops moving to the outside. The elasticity generated by the stretching of the elastic rope causes the impact ball to strike the dust baffle. After the air inside the device stops moving, the impact generates vibration to prevent dust from adhering to the inner wall of the device, thereby improving the cleanliness of the device and preventing dust from being carried outside the device by the flowing air due to premature vibration.

[0016] (III) Beneficial Effects

[0017] This invention provides a mine rail transport vehicle. It has the following beneficial effects:

[0018] (i) The mine rail transport vehicle uses a lifting plate that is pressed down by ore. The lifting plate presses the limiting post down to the outside of the transport frame, which in turn presses and bends the buffer spring and elastic plate. As the amount of ore inside the transport frame gradually increases, the bending of the buffer spring and elastic plate gradually increases. The angle between the bottom of the elastic plate and the bottom of the transport frame gradually decreases. Finally, one end of the bottom of the elastic plate slides to the outside of the limiting frame and is close to the bottom of the transport frame. This improves the buffering capacity of the mine transport equipment, reduces the space occupied by the buffer structure, and improves the transport capacity of the mine transport equipment.

[0019] (II) During the descent of the mine rail transport vehicle via the lifting plate, the space inside the extraction trough above the lifting plate gradually increases, and the air pressure inside the extraction trough above the lifting plate decreases. This draws the air around the extraction column into the extraction trough through the extraction port. Dust particles generated around the transport frame due to ore handling enter the extraction trough with the air and settle inside. As the lifting plate is pushed upward by the buffer spring and elastic plate, the air inside the extraction trough is discharged through the extraction port, improving the air purification capacity of the device. This removes dust generated by ore handling from the air and optimizes the working environment during mine construction.

[0020] (III) The mine rail transport vehicle allows air around the transport frame to enter the air extraction slot through the air extraction hole. Dust in the air settles below the dust baffle. When the buffer spring and elastic plate push the lifting plate upward, the air inside the air extraction slot is pushed out through the air extraction hole. When the dust inside the air extraction slot is moved upward by the air, it is blocked by the dust baffle. This effectively fixes the filtered dust in the air and prevents the dust from re-entering the air and causing secondary pollution to the air environment of the mine construction.

[0021] (iv) The mine rail transport vehicle, through the elastic rope and impact ball, rises with the lifting plate. The elastic rope is stretched and elongated. When the lifting plate rises to the highest point, the air inside the exhaust trough stops moving to the outside. The elasticity generated by the stretching of the elastic rope drives the impact ball to hit the dust baffle. After the air inside the device stops moving, the impact generates vibration to prevent dust from adhering to the inner wall of the device, improve the cleanliness of the device, and prevent dust from being carried to the outside of the device by the flowing air due to premature vibration.

[0022] (v) The mine rail transport vehicle can collect the dust filtered in the air by sliding the dust that settles inside the air extraction trough from the discharge trough into the receiving frame, which reduces the difficulty of dust treatment.

[0023] (vi) The mine rail transport vehicle is pressed down by the lifting plate by the limiting column and then attracted by the magnetic block. After the upper and lower columns are completely lowered outside the transport frame, they are attracted by the magnetic block and hit the receiving frame, and finally adsorbed on the receiving frame. The sound generated by the impact can be used to alarm the ore loading amount. When the limiting column hits the receiving frame and produces a sound several times, the loading stops and the transport continues, which improves the intelligence level of the device.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] Please see Figure 1-4 The present invention provides a technical solution: a mine rail transport vehicle, including a transport frame 1, with rollers 2 symmetrically installed on the bottom of the transport frame 1, and the interior of the transport frame 1 being provided with:

[0033] The air extraction device 3 has an air extraction column 31, which is symmetrically installed on the inner bottom of the transport frame 1. An air extraction groove 32 is opened inside the air extraction column 31, and air extraction holes 33 are symmetrically opened on the top of the air extraction column 31. The air extraction holes 33 are connected to the air extraction groove 32. One end of the bottom of the air extraction groove 32 passes through the air extraction column 31. A lifting plate 34 is slidably connected between the two sides of the inner wall of the transport frame 1. The lifting plate 34 extends into the interior of the air extraction groove 32. A sealing folding plate 35 is slidably connected between the two sides of the inner wall of the air extraction groove 32. The bottom of the sealing folding plate 35 is fixedly connected to the lifting plate 34.

[0034] The buffer device 4 has a limiting post 41. The top end of the limiting post 41 is fixedly connected to the lifting plate 34. The bottom of the limiting post 41 passes through the transport frame 1 and extends to the outside of the transport frame 1. A buffer spring 42 is sleeved on the outside of the limiting post 41. An elastic plate 43 is fixedly connected to the bottom of the lifting plate 34.

[0035] A limiting frame 9 is fixedly connected to the bottom inner side of the transport frame 1, and one end of the bottom of the elastic plate 43 extends into the interior of the limiting frame 9 and is slidably connected to the limiting frame 9.

[0036] In use, a transport vehicle moves the transport frame 1 to the location where the ore needs to be transported. The ore is then placed inside the transport frame 1, and the ore presses down on the lifting plate 34. The lifting plate 34 then presses the limiting post 41 down to the outside of the transport frame 1, which in turn presses and bends the buffer spring 42 and the elastic plate 43. As the amount of ore inside the transport frame 1 gradually increases, the bending range of the buffer spring 42 and the elastic plate 43 gradually increases, and the tilt angle between the bottom of the elastic plate 43 and the bottom of the transport frame 1 gradually decreases. Finally, one end of the bottom of the elastic plate 43 slides to the outside of the limiting frame 9 and is almost horizontal with the bottom of the transport frame 1. This improves the buffering capacity of the mining transport equipment, reduces the space occupied by the buffer structure, and improves the transport capacity of the mining transport equipment.

[0037] During the process of feeding ore into the transport frame 1, the lifting plate 34 first compresses the buffer spring 42 and the elastic plate 43 to descend. As the lifting plate 34 descends, the sealing folding plate 35 blocks the gap in the suction groove 32 located above the lifting plate 34. Then, due to their own elasticity, the buffer spring 42 and the elastic plate 43 push the lifting plate 34 upward a certain distance. During the descent of the lifting plate 34, the space inside the suction groove 32 located above the lifting plate 34 gradually increases, and the air pressure inside the suction groove 32 located above the lifting plate 34 decreases. This draws the air around the suction column 31 into the suction groove 32 through the suction hole 33. Dust particles generated around the transport frame 1 due to ore handling enter the suction groove 32 with the air and settle inside the suction groove 32. As the lifting plate 34 is pushed upward by the buffer spring 42 and the elastic plate 43, the air inside the suction groove 32 is discharged through the suction hole 33, improving the air purification capacity of the device, removing dust generated by ore handling from the air, and optimizing the working environment of the mine construction.

[0038] Example 2

[0039] Please see Figure 1-5 The present invention provides a technical solution: Based on the first embodiment, the limiting post 41 has an upper post 5 and a lower post 6, which are alternately connected. The bottom of the upper post 5 and the lower post 6 are provided with limiting grooves 7, and the ends of the upper post 5 and the lower post 6 away from the limiting grooves 7 are fixedly connected with limiting blocks 8.

[0040] The outer side of the transport frame 1 is symmetrically provided with a discharge trough 10. The discharge trough 10 passes through the transport frame 1 and the air extraction column 31 and is connected to the air extraction trough 32. Both sides of the transport frame 1 are fixedly connected to a receiving frame 11 below the discharge trough 10.

[0041] A magnet block 12 is installed on one side of the receiving frame 11, and the limiting post 41 is made of magnetic metal.

[0042] The top of the lifting plate 34 is fixedly connected to the inner side of the air extraction slot 32 with a longitudinal column 13, and the top of the longitudinal column 13 is fixedly connected to a dust baffle 14.

[0043] An elastic rope 15 is fixedly connected to the bottom of the dust baffle 14, and an impact ball 16 is fixedly connected to the end of the elastic rope 15 away from the dust baffle 14.

[0044] During use, the air around the transport frame 1 enters the air extraction slot 32 through the air extraction hole 33. The dust in the air settles below the dust baffle 14. When the buffer spring 42 and the elastic plate 43 push the lifting plate 34 to rise, the air inside the air extraction slot 32 is pushed out through the air extraction hole 33. When the dust inside the air extraction slot 32 is carried upward by the air, it is blocked by the dust baffle 14, which can effectively fix the filtered dust in the air and prevent the dust from re-entering the air and causing secondary pollution to the air environment of the mine construction.

[0045] After the limiting column 41 is pressed down by the lifting plate 34 to the outside of the transport frame 1, it is attracted by the magnet 12. After the upper column 5 and the lower column 6 are completely lowered to the outside of the transport frame 1, they are attracted by the magnet 12 and hit the receiving frame 11, and finally adsorbed on the receiving frame 11. The sound generated by the impact can be used to alarm the ore loading amount. After the limiting column 41 hits the receiving frame 11 and makes a sound several times, the loading stops and the transport is carried out, which improves the intelligence level of the device.
