Description

Technical Field

[0001] The present invention relates to the technical field of mining machinery, and more particularly to a stable structure of a mining machinery elevator car. Background Art

[0002] The elevator car of the mining hoist system is towed or suspended by traction media such as steel ropes or steel belts. Especially when the elevator car stops at a certain floor position to load / unload items, the elevator car is suspended by the steel ropes or steel belts and stops relatively in the hoistway, making loading or unloading convenient.

[0003] However, traction media such as steel ropes or steel belts are somewhat elastic. If the weight of the elevator car fluctuates significantly during loading or unloading, it can easily cause vertical vibrations in the elevator car, especially when the ropes or belts are long. This vibration can lead to unstable parking of the elevator car relative to a floor and a poor operator experience. Summary of the Invention

[0004] In response to the deficiencies in the prior art, the present invention aims to provide a stable structure for a mining machinery elevator car, in which the closing of the car door drives the sliding part to slide toward the direction close to the T-shaped slide rail, so that the plug-in plates on the first plug-in part and the second plug-in part are plugged into the corresponding slots, completing the positioning plug-in of the first plug-in part, the second plug-in part and the T-shaped slide rail. When the elevator car vibrates due to loading and unloading mineral materials, the elevator car drives the sliding part to vibrate synchronously, and the buffering effect of the first damper and the second damper absorbs the energy of the elevator car vibration, so that the vibration of the elevator car is reduced or suppressed, thereby improving the stability of the elevator car during loading and unloading mineral materials and improving the operator's experience.

[0033] For example 1, please refer to Figure 1-12 , the present invention provides the following technical solutions:

[0034] A stable structure for a mining machinery elevator car, specifically, comprises a T-shaped slide rail 1 symmetrically fixedly installed in a mine shaft and an elevator car 2 slidably arranged on the two T-shaped slide rails 1; a slide plate 3 is symmetrically slidably arranged on the bottom surface of the elevator car 2; a retaining frame 4 is installed at the bottom of the elevator car 2; the retaining frame 4 comprises a retaining rod 5 fixed to the bottom surface of the elevator car 2; two sets of guide plates 6 are slidably arranged on the retaining rod 5 from top to bottom; a sliding part 7 is fixed on the slide plate 3; a first plug-in part 8 and a second plug-in part 9 are slidably arranged on the inner wall of the sliding part 7 from top to bottom; the sliding part 7 comprises a fixed part fixed to the slide plate 3 A U-shaped plate 10 is fixedly connected; an L-shaped support plate 11 is fixed to the bottom surface of the U-shaped plate 10; a first damper 12 is fixed to the surface of the L-shaped support plate 11; the first plug-in portion 8 and the second plug-in portion 9 both include a plug-in plate 13; a plurality of slots 14 for plugging with the plug-in plate 13 are evenly opened on the side of the T-shaped slide rail 1 from top to bottom; a second damper 15 is installed on the surface of the plug-in plate 13 on the first plug-in portion 8; an ear plate 16 is fixed to the side of the U-shaped plate 10; the telescopic end of the first damper 12 is fixedly connected to the bottom surface of the plug-in plate 13 on the second plug-in portion 9; the telescopic end of the second damper 15 is fixedly connected to the bottom surface of the ear plate 16.

[0035] Working principle of this embodiment 1:

[0036] By closing the car door 19, the sliding part 7 is driven to slide toward the direction close to the T-shaped slide rail 1, so that the plug-in plates 13 on the first plug-in part 8 and the second plug-in part 9 are plugged into the corresponding slots 14, completing the positioning plug-in of the first plug-in part 8, the second plug-in part 9 and the T-shaped slide rail 1. When the elevator car 2 vibrates due to loading and unloading mineral materials, the elevator car 2 drives the sliding part 7 to vibrate synchronously. Through the buffering effect of the first damper 12 and the second damper 15, the energy of the vibration of the elevator car 2 is absorbed, so that the vibration of the elevator car 2 is reduced or suppressed, thereby improving the stability of the elevator car 2 during loading and unloading mineral materials and improving the operator's experience.

[0037] For example 2, please refer to Figure 1-12 The second embodiment makes the following improvements on the basis of the first embodiment. Specifically, a mining elevator is installed on the top of the mine shaft; a steel rope 17 is wound on the elevator; the top of the elevator car 2 is suspended on one end of the steel rope 17; and lifting grooves that slide with the T-shaped slide rail 1 are opened on the opposite sides of the elevator car 2.

[0038] By controlling the forward and reverse rotation of the mining elevator, the steel rope 17 is driven to be wound and released, thereby driving the elevator car 2 to rise and fall, and then realizing the transportation of the ore by the elevator car 2.

[0039] One side of the elevator car 2 is open, and sliding cavities 18 are provided on both sides opposite to the opening; a car door 19 is slidably provided inside the sliding cavity 18; an L-shaped slide rail 20 is fixed to the bottom surface of the car door 19; a slide groove 21 that slides with the L-shaped slide rail 20 is provided on the bottom surface of the elevator car 2; a fixed plate 22 is fixed to the top of the retaining rod 5; the fixed plate 22 is fixedly installed on the bottom surface of the elevator car 2 by fastening bolts; an avoidance hole 23 that is compatible with the fixed plate 22 is provided on the surface of the L-shaped slide rail 20.

[0040] The fixing plate 22 is fixedly installed on the bottom surface of the elevator car 2 by tightening the bolts to complete the fixation of the retaining frame 4. The opening and closing of the car door 19 is achieved by controlling the sliding of the car door 19 inside the sliding cavity 18. The specific control of the opening and closing of the car door 19 is an existing technology and will not be elaborated here.

[0041] Ear seats 24 are symmetrically fixed to the bottom surface of the elevator car 2 on both sides of the corresponding T-shaped slide rail 1; a guide rod 25 is fixed between the two opposite ear seats 24; sliding sleeves 26 that slide with the corresponding guide rods 25 are fixed on the opposite side surfaces of the slide plate 3; a return spring 27 mounted on the corresponding guide rod 25 is fixed between the sliding sleeve 26 and the corresponding ear seat 24; a plurality of mounting holes 28 are opened on the side surface of the slide plate 3 and the inner wall of the U-shaped plate 10; the slide plate 3 and the U-shaped plate 10 are plugged into each other and the two are fixedly connected by fastening bolts.

[0042] When the car door 19 is closed, the slide plate 3 is driven by the elastic force of the return spring 27 to abut against the corresponding L-shaped slide rail 20 and the side of the vertical plate 45.

[0043] A guide groove 29 is provided on the side of the L-shaped support plate 11, which slides with the plug-in plate 13; limiting grooves 30 are symmetrically provided on both sides of the inner wall of the guide groove 29; guide rails 31 that slide with the limiting grooves 30 are symmetrically fixed on the opposite sides of the plug-in plate 13; positioning plates 32 are fixed on both opposite sides of the plug-in plate 13; positioning grooves 33 that plug and cooperate with the corresponding positioning plates 32 are symmetrically provided on the inner wall of the slot 14.

[0044] By controlling the plug-in board 13 to be inserted into the corresponding guide groove 29, during this process, the positioning plate 32 is inserted into the corresponding positioning groove 33, so that the corresponding plug-in boards 13 on the first plug-in part 8 and the second plug-in part 9 cannot move in the vertical direction, while the elevator car 2 together with the sliding part 7 can move in the vertical direction, and cooperate with the first damper 12 and the second damper 15 to achieve the absorption of the vibration energy of the elevator car 2; the plug-in cooperation between the positioning plate 32 and the positioning groove 33 can prevent the plug-in board 13 from lateral displacement, thereby further improving the anti-vibration ability.

[0045] A through groove 34 is provided inside the plug board 13, which slides with the guide plate 6; a sleeve 35 is fixed between the two guide plates 6, which slides with the retaining rod 5; an upper retaining ring 36 is fixed to the side of the retaining rod 5; a lower retaining ring 37 is fixed to the bottom end of the retaining rod 5; a guide rail 38 is fixed to the side of the retaining rod 5 between the upper retaining ring 36 and the lower retaining ring 37; and a guide groove is provided on the inner wall of the sleeve 35, which slides with the guide rail 38.

[0046] Through the sliding cooperation between the guide rail 38 and the guide groove, the retaining rod 5 can only slide in the vertical direction along the two guide plates 6, while ensuring that the two guide plates 6 do not rotate.

[0047] An L-shaped extension plate 39 is fixed to the side of the guide plate 6; an insertion rod 40 is slidingly set through the side of the L-shaped extension plate 39; a ball head 41 is fixed to one end of the insertion rod 40; a support spring 42 mounted on the insertion rod 40 is fixedly connected between the ball head 41 and the side of the L-shaped extension plate 39; the side of the guide plate 6 and the side of the retaining rod 5 are provided with a socket 43 that is plugged into and cooperates with the insertion rod 40.

[0048] A vertical plate 45 is fixed to the bottom surface of the L-shaped slide rail 20 on a car door 19; two sets of guide parts are fixed from top to bottom on the vertical plate 45; the guide parts include a first transverse guide plate 46 and a second transverse guide plate 47 arranged parallel to each other; an inclined guide plate 48 is fixedly connected between the first transverse guide plate 46 and the second transverse guide plate 47

[0049] When the two car doors 19 are closed, the ball head 41 is pressed against the bottom surface of the second cross guide plate 47 under the elastic force of the support spring 42, and the support spring 42 is in a compressed state. At this time, the insertion rod 40 is inserted into the insertion hole 43 on the side of the guide plate 6 and the side of the retaining rod 5, completing the plug-in fixation of the two sets of guide plates 6 and the retaining rod 5, and the two plug-in plates 13 are disengaged from the corresponding slots 14.

[0050] During the opening process of the car door 19, the ball head 41 first slides on the bottom surface of the second cross guide plate 47, and the plug-in plate 13 slides toward the corresponding slot 14. When the ball head 14 slides on the inclined guide plate 48, the plug-in plate 13 is inserted into the slot 14. At this time, the plug rod 40 slides along the corresponding socket 43 but does not disengage. The plug-in plate 13 continues to be inserted into the slot 14. When the ball head 41 slides to the bottom surface of the first cross guide plate 46, the plug-in plate 13 abuts against the inner wall of the slot 14, and the plug rod 40 slides out of the socket 43.

[0051] During the closing process of the car door 19, the ball head 41 first slides on the bottom surface of the first cross guide plate 46, and the plug-in plate 13 slides outward along the slot 14. When the ball head 41 slides on the inclined guide plate 48, the plug-in rod 40 is inserted into the socket 43. At this time, the plug-in plate 13 is not disengaged from the slot 14. When the ball head 41 slides to the bottom surface of the second cross guide plate 47, the plug-in plate 13 slides out of the slot 14.

[0052] A first corrugated protective tube 44 is connected between the telescopic ends and the corresponding fixed ends of the first damper 12 and the second damper 15 ; a second corrugated protective tube is connected between the L-shaped extension plate 39 and the ball head 41 .

[0053] The provision of the first corrugated protective tube 44 protects the telescopic ends of the first damper 12 and the second damper 15, preventing them from being contaminated by external mining dust; the provision of the second corrugated protective tube prevents the support spring 42 from being contaminated by external mining dust.

[0054] Working principle of the second embodiment:

[0055] When the mining elevator is controlled to drive the steel rope 17 to descend to the designated floor, the two sets of plug-in plates 13 are aligned with the corresponding slots 14, and the positioning plates 32 are aligned with the corresponding positioning grooves 33, and the car door 19 is controlled to be stored in the corresponding sliding cavity 18, so that the car door 19 is opened. During this process, the car door 19 drives the corresponding L-shaped slide rail 20 to slide synchronously, squeezing the corresponding slide plate 3, and the corresponding return spring 27 is compressed. The ball head 41 slides from the second cross guide plate 47 to the inclined guide plate 48. The elastic reset force of the reset spring 27 drives the ball head 41 to press against the inclined guide plate 48. During the sliding of the ball head 41 on the inclined guide plate 48, the plug-in plate 13 is first inserted into the corresponding slot 14, and then the plug-in rod 40 slides out of the corresponding socket 43, releasing the plug-in fixation of the retaining rod 5 and the two guide plates 6. Under the elastic reset force of the reset spring 27, the ball head 41 is driven to press against the bottom surface of the first cross guide plate 46. At this time, the retaining rod 5 can move synchronously with the elevator car 2.

[0056] When the elevator car 2 is loaded and unloaded with mineral materials, the steel rope 17 drives the elevator car 2 to vibrate. Since the corresponding plug-in plates 13 on the first plug-in part 8 and the second plug-in part 9 cannot move in the vertical direction, when the elevator car 2 floats up, the first damper 12 is contracted by the upward pull of the L-shaped support plate 11, and the telescopic end of the second damper 15 is extended by the upward pull of the ear plate 16. When the elevator car 2 sinks, the first damper 12 is extended by the downward pull of the L-shaped support plate 11, and the second damper 15 is contracted by the downward thrust of the ear plate 16, thereby absorbing the energy generated by the vibration process of the elevator car 2, so that the vibration of the elevator car 2 is reduced or suppressed, thereby improving the stability of the elevator car 2 when loading and unloading mineral materials and improving the operator's experience.

[0057] After completing the loading and unloading of the mineral materials, when the elevator car 2 is stable, the two car doors 19 are controlled to slide out from the corresponding sliding cavity 18 to realize the closing of the two car doors 19. During this process, the ball head 41 slides from the bottom surface of the first cross guide plate 46 to the inclined guide plate 48. During the sliding of the ball head 41 on the inclined guide plate 48, the plug rod 40 is first inserted into the corresponding socket 43, and then the plug-in plate 13 slides out of the corresponding slot 14, keeping the two guide plates 6 in the designated position on the retaining rod 5 unchanged, so that the plug-in plate 13 can be accurately inserted into the corresponding slot 14 in the future, thereby improving the accuracy of the device operation.
