Description

Technical Field

[0001] The present invention relates to the technical field of vehicle MU posture correction, and in particular to a mining vehicle MU posture correction device and correction method. Background Art

[0002] Mine car posture correction is a key technology to ensure the stable operation of mine cars in complex track environments, especially in scenarios such as turns, slopes, and load changes. It can effectively prevent derailment, rollover, and abnormal wheel-rail wear. Mine tracks are often deformed due to geological subsidence, mechanical vibration, etc., which can easily cause mine cars to tilt or shift.

[0003] During use, the existing MU posture correction equipment for mining vehicles has a problem. When passing through a curve, the centrifugal force on the outer tire is too large due to the contact of the two sets of tires. As a result, the outer wheel of the vehicle deviates due to the excessive centrifugal force when turning, which in turn causes the vehicle to roll over, seriously affecting the use of the device and easily causing economic losses.

The first spring squeezes the moving wheel to move the moving wheel, and at the same time, the outer group of first springs are stretched, thereby driving the outer group of moving wheels to move forward inside the limiting plate through the movable rod, so that the two groups of moving wheels are separated. When turning, the outer wheel contacts the curve first, guides the steering in advance, reduces the lateral impact of the inner wheel rim, and at the same time gives an early warning before turning to avoid the sudden turn affecting the device and causing the moving wheel to deviate from the track.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The present invention provides a mining vehicle MU posture correction device, comprising a storage box 1, one end of which is provided with an auxiliary mechanism 2; The auxiliary mechanism 2 includes a shock-absorbing chassis 21 provided at the bottom of the storage box 1, a connecting rod 22 is provided at one end of the shock-absorbing chassis 21, a rotating shaft 23 rotating at one end of the connecting rod 22 is passed through one end of the connecting rod 22, a first limiting rod 26 is provided at both ends of the rotating shaft 23, a first spring 28 is further provided at one end of the first limiting rod 26, and a correction mechanism 3 is further provided at one end of the first spring 28; The correction mechanism 3 includes a limiting plate 31 fixed at both ends of the shock-absorbing chassis 21, a movable rod 32 is inserted into the limiting plate 31, a movable wheel 33 is provided at one end of the movable rod 32, a first rack 34 is provided on one side of the movable rod 32, a gear 37 is rotated at the upper end of the first rack 34, a second rack 38 is engaged with one side of the gear 37, a baffle 311 is provided at one end of the second rack 38, and telescopic sleeves 312 are respectively provided on both sides of the movable wheel 33.

[0024] Before using this device, by placing the device on the track and inserting the first limiting rods 26 at both ends into the track, when the device is running on the track and the device needs to turn, the group of first limiting rods 26 on the inner side of the curve is compressed, and the group of first limiting rods 26 on the outer side of the curve is extended, so that the rotating shaft 23 rotates when turning, and the rotation of the rotating shaft 23 drives the inner first spring 28 to be compressed, and the first spring 28 squeezes the moving wheel 33, so that the moving wheel 33 moves. At the same time, the outer group of first springs 28 is stretched, thereby driving the outer group of moving wheels 33 to move forward inside the limiting plate 31 through the movable rod 32, so that the two groups of moving wheels 33 separate. When turning, the outer wheel contacts the curve first, guiding the steering in advance, reducing the lateral impact of the inner wheel rim, and at the same time giving an early warning before turning to avoid the sudden turn affecting the device and causing the moving wheel 33 to deviate from the track.

[0025] At the same time, the telescopic sleeves 312 and the fourth springs 313 on both sides of the moving wheel 33 enable the moving wheel 33 to move to a certain extent on the transmission shaft, thereby increasing the adaptability to the track.

[0026] At the same time, the limiting plate 31 is squeezed, squeezing the first rack 34 on one side. The first rack 34 moves under the restriction of the limiting plate 314, driving the gear 37 to rotate. The rotation of the gear 37 drives the second rack 38 to rise. The second rack 38 slides on the second limiting rod 310, driving the baffle 311 on one side to rise. When turning, the inner baffle 311 rises to prevent the vehicle from rolling over when turning, thereby improving the safety and stability of the vehicle operation. At the same time, after the turn is completed, the third spring 36 squeezes and resets the first rack 34, so that the two sets of moving wheels 33 return to their original positions and the vehicle travels normally.

[0027] In an optional embodiment, a rotating rod 24 is provided through the rotating shaft 23, and connecting hands 25 are provided on both sides of the rotating rod 24. Both ends of the connecting hands 25 are respectively connected to the first limiting rod 26, and the first limiting rod 26 is designed to be retractable.

[0028] It should be noted that the first limiting rod 26 is squeezed against the outer track so that the first limiting rod 26 is restricted in the track. When a turn is required, the moving wheel 33 is warned, and the squeezing of the first limiting rod 26 by the track drives the rotating rod 24 to rotate around the rotating shaft 23, driving the first spring 28 to expand and contract, thereby assisting the moving wheel 33 and preventing the moving wheel 33 from leaving the track due to a sudden turn, causing damage to the device, causing the loaded material to fall out, causing economic losses, and increasing the labor intensity of the staff.

[0029] In an optional embodiment, a hose 27 is provided on the outside of the first spring 28, and the two ends of the hose 27 are respectively connected to the rotating rod 24 and the moving wheel 33. Multiple groups of second springs 29 are provided on the upper end of the shock-absorbing chassis 21, and the upper end of the second spring 29 is connected to the storage box 1.

[0030] It should be noted that the vibration of the storage box 1 is slowed down by the second spring 29, thereby reducing the impact of high-frequency vibration on the device during operation. At the same time, the rotating rod 24 rotates around the rotating shaft 23 when turning, so that the rotating rod 24 stretches and contracts the first springs 28 on both sides, so that the inner first spring 28 is compressed when turning, thereby squeezing the inner moving wheel 33, and the outer first spring 28 is stretched, so that the outer moving wheel 33 is pulled, so that the outer wheel contacts the curve first when turning, guiding the steering in advance and reducing the lateral impact of the inner wheel rim.

[0031] In an optional embodiment, a first support plate 35 is provided at the bottom of the first rack 34 , a limiting plate 314 is provided on the first support plate 35 , the first rack 34 slides on the limiting plate 314 , and one side of the first support plate 35 is connected to the shock-absorbing chassis 21 .

[0032] It should be noted that the first rack 34 slides inside the first support plate 35 and at the same time slides outside the limiting plate 314, thereby limiting the first rack 34 and preventing the first rack 34 from detaching during sliding and affecting the normal operation of the device.

[0033] In an optional embodiment, a third spring 36 is provided at one end of the first rack 34 , and one end of the third spring 36 is connected to the first support plate 35 .

[0034] It should be noted that after the turn is completed, the pressure of the track on the first limiting rod 26 is reduced, so that the rotating rod 24 returns to its original position, and the first spring 28 does not apply force to the moving wheels 33 on both sides, so that the third spring 36 squeezes the first rack 34, so that the moving wheels 33 return to their original position, facilitating the normal operation of the device.

[0035] In an optional embodiment, a second support plate 39 is provided on one side of the gear 37 , the gear 37 rotates on the second support plate 39 , and one side of the second support plate 39 is connected to the first support plate 35 .

[0036] It should be noted that the gear 37 rotates on the second support plate 39 under the push of the first rack 34, while driving the second rack 38 on one side to move, and then driving the baffle 311 to move, protecting the device when turning and preventing the device from tipping over.

[0037] In an optional embodiment, a second limiting rod 310 is provided through the interior of the second rack 38 , and the upper end of the second limiting rod 310 is connected to the storage box 1 .

[0038] It should be noted that the second rack 38 moves on the second limiting rod 310 when moving, which limits the second rack 38 and prevents the second rack 38 from deviating from the track when moving, thereby affecting the normal operation of the device.

[0039] In an optional embodiment, a fourth spring 313 is provided inside the telescopic sleeve 312 , and the telescopic sleeve 312 is designed to be telescopic.

[0040] It should be noted that when the moving wheel 33 is squeezed, the fourth springs 313 on both sides and the telescopic sleeve 312 are extended and retracted, so that the moving wheel 33 can move within a certain range, thereby improving the stability of the device.

[0041] A method for correcting a mining vehicle MU posture correction device, the method of using the device comprises the following steps: Step 1: Place the device on the track, start the device to transport the mineral, and clamp the first limiting rod 26 on the track to make the rotating rod 24 move on the track.

[0042] Step 2: When turning, the first limiting rods 26 on both sides are squeezed under the pressure of the track, causing the rotating rod 24 to rotate around the rotating shaft 23. The rotation of the rotating shaft 23 drives the first springs 28 on both sides to expand and contract.

[0043] Step 3: When turning, the outer first spring 28 stretches the moving wheel 33, and the inner first spring 28 squeezes the moving wheel 33, so that the moving wheel 33 drives the movable rod 32 to move inside the limiting plate 31 and squeezes the first rack 34 on one side.

[0044] Step 4: The first rack 34 is squeezed and moved to drive the gear 37 to rotate, thereby driving the baffle 311 to rise, so that when the vehicle turns, the inner baffle 311 rises.

[0045] Working principle: Before using this device, the device is placed on the track and the first limiting rods 26 at both ends are inserted into the track. When the device is running on the track and the device needs to turn, a group of first limiting rods 26 on the inner side of the curve is compressed, and a group of first limiting rods 26 on the outer side of the curve is extended, so that the rotating shaft 23 rotates when turning. The rotation of the rotating shaft 23 drives the inner first spring 28 to be compressed, and the first spring 28 squeezes the moving wheel 33, so that the moving wheel 33 moves. At the same time, the outer group of first springs 28 is stretched, thereby driving the outer group of moving wheels 33 to move forward inside the limiting plate 31 through the movable rod 32, so that the two groups of moving wheels 33 separate. When turning, the outer wheel contacts the curve first, guides the steering in advance, reduces the lateral impact of the inner wheel rim, and issues an early warning before turning to avoid the sudden turn affecting the device and causing the moving wheel 33 to deviate from the track.

[0046] At the same time, the telescopic sleeves 312 and the fourth springs 313 on both sides of the moving wheel 33 enable the moving wheel 33 to move to a certain extent on the transmission shaft, thereby increasing the adaptability to the track.

[0047] At the same time, the limiting plate 31 is squeezed, squeezing the first rack 34 on one side. The first rack 34 moves under the restriction of the limiting plate 314, driving the gear 37 to rotate. The rotation of the gear 37 drives the second rack 38 to rise. The second rack 38 slides on the second limiting rod 310, driving the baffle 311 on one side to rise. When turning, the inner baffle 311 rises to prevent the vehicle from rolling over when turning, thereby improving the safety and stability of the vehicle operation. At the same time, after the turn is completed, the third spring 36 squeezes and resets the first rack 34, so that the two sets of moving wheels 33 return to their original positions and the vehicle travels normally.

[0048] The gear 37 rotates on the second support plate 39 under the push of the first rack 34, and at the same time drives the second rack 38 on one side to move, and then drives the baffle 311 to move, thereby protecting the device when turning and preventing the device from tipping over. When the second rack 38 moves, it moves on the second limiting rod 310 to limit the second rack 38 to prevent the second rack 38 from leaving the track when moving, thereby affecting the normal operation of the device. The first rack 34 slides inside the first support plate 35, and at the same time, the first rack 34 slides outside the limiting plate 314, thereby limiting the first rack 34 to prevent the first rack 34 from leaving when sliding, thereby affecting the normal operation of the device.

[0049] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
