Description

TECHNICAL FIELD

[0001] The present disclosure belongs to the technical field of material transportation, and particularly relates to a lifting transportation device. BACKGROUND

[0002] In the process of energy exploitation, it is often necessary to transport underground materials to the ground. For example, in the process of coal mining.

[0003] In the related art, many underground coal mines generally use lifting transportation devices to transport underground coal. The lifting transportation device includes a friction hoist winch, a traction rope, and a coal bucket. The traction rope is wound around the drum of the friction hoist winch, and the traction rope is connected to the coal bucket. In order to improve the transportation efficiency, two coal buckets are used, and the two coal buckets are counterbalanced and connected by a counterweight rope. While one coal bucket is ascending with a full load of coal, the other coal bucket is descending with an empty load.

[0004] However, when the friction hoist winch lifts the coal bucket, the traction rope and the drum of the friction hoist winch are driven by friction. If the traction rope slips on the drum, the traction rope will uncontrollably ascend and descend, which is very dangerous. In order to increase the friction, a friction pad made of rubber material is provided on the drum. The friction pad increases the friction between the drum and the traction rope. However, the friction pad is easily worn and often needs to be replaced. Moreover, the replacement of the friction pad is complex and expensive, which increases the overall transportation cost.

[0017] When the lifting and transporting device provided by the present disclosure is used for coal conveying, since the lifting and transporting device comprises a track assembly, a moving assembly, a connecting and guiding assembly and a coal conveying assembly, and the coal conveying assembly comprises two coal conveying buckets, the two coal conveying buckets can be used to load coal. Meanwhile, since the moving assembly can move along the length direction of the track assembly relative to the track assembly, and each traction rope is connected to one end of the moving assembly and one corresponding coal conveying bucket, when the moving assembly moves along the track assembly, the two traction ropes can be used to pull the coal conveying buckets.

[0040] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the following will further describe the embodiments of the present disclosure in combination with the drawings.

[0041] Figure 1 is structure diagram of lifting and transporting device in related art, such as Figure 1As shown, in the related art, when underground coal is transported, a friction hoist winch, a traction rope 31 and a coal bucket 41 are generally used for transportation. The traction rope 31 is wound around the drum 100 of the friction hoist winch, and the traction rope 31 is connected with the coal bucket 41. In order to improve the transportation efficiency, the coal bucket 41 is two, and the traction rope 31 between the two coal buckets 41 passes through the drum 100, so that the two coal buckets 41 are located on both sides of the drum 100. The two coal buckets 41 are counterweights. One coal bucket 41 is filled with coal and rises at the same time, and the other coal bucket 41 is empty and descends. In order to balance the weight of the traction rope 31, a counterweight rope 40 is connected at the bottom of the two coal buckets 41. In this way, the friction hoist winch only provides the driving force to drive the coal weight to rise.

[0042] When the lifting friction winch lifts the coal bucket, the traction rope and the drum are driven by friction between the two, and the traction rope and the drum are relatively static, that is, the linear speed of the drum surface and the linear speed of the traction rope are the same. The drum is driven by a driving motor, and after the drum rotates, the traction rope is lifted, so that the lifting power of the coal bucket is completely transmitted by the friction between the traction rope and the drum. If the traction rope slips on the drum, the traction rope will be uncontrollably lifted, which is very dangerous.

[0043] In addition, in order to increase the winding angle of the traction rope on the drum, the above transportation device will be configured with a guide pulley 101, and at the same time, the weight of the coal bucket is increased, so that the weight difference on both sides of the drum is as small as possible, and the required effective lifting friction is reduced.

[0044] The embodiment of the present disclosure provides a lifting transportation device, which comprises a track assembly 1, a moving assembly 2, a connecting guide assembly 3 and a coal conveying assembly 4. Figure 2 As shown, the lifting transportation device comprises a track assembly 1, a moving assembly 2, a connecting guide assembly 3 and a coal conveying assembly 4.

[0045] The moving assembly 2 can move along the length direction of the track assembly 1 relative to the track assembly 1. The coal conveying assembly 4 is located on one side of the track assembly 1 along the length direction of the track assembly 1, and comprises two coal buckets 41 connected by a counterweight rope 40.

[0046] The connecting guide assembly 3 comprises two traction ropes 31 and a pulley set 33. The two traction ropes 31 correspond to the two coal buckets 41 one by one, and the two traction ropes 31 are respectively located at both ends of the moving direction of the moving assembly 2, and the two ends of each traction rope 31 in the two traction ropes 31 are respectively connected with the moving assembly 2 and the corresponding one of the two coal buckets 41. The pulley set 33 is slidably connected with the two traction ropes 31, and the pulley set 33 is configured to guide the two traction ropes 31, so that when the moving assembly 2 moves, one of the two coal buckets 41 rises and the other one descends.

[0047] When the lifting transportation device provided by the embodiment of the present disclosure is used for coal transportation, since the lifting transportation device comprises the track assembly 1, the moving assembly 2, the connecting and guiding assembly 3 and the coal conveying assembly 4, and the coal conveying assembly 4 comprises two coal conveying buckets 41, the coal can be loaded by the two coal conveying buckets 41. At the same time, since the moving assembly 2 can move along the length direction of the track assembly 1 relative to the track assembly 1, and each traction rope 31 is connected with one end of the moving assembly 2 and the corresponding coal conveying bucket 41 respectively, when the moving assembly 2 moves along the track assembly 1, the coal conveying bucket 41 can be pulled by the two traction ropes 31.

[0048] Since the pulley block 33 is connected with the two traction ropes 31 respectively, the pulley block 33 is configured to guide the two traction ropes 31, so that when the moving assembly 2 moves, one of the two coal conveying buckets 41 rises and the other falls, so that when the moving assembly 2 reciprocates, one of the two coal conveying buckets 41 is continuously lifted and the other is continuously lowered, so as to transport the coal in the coal conveying bucket 41 from the underground to the ground.

[0049] Since the above lifting transportation device drives the coal conveying bucket 41 to rise or fall by the movement of the moving assembly 2, the friction lifting winch is avoided to drive the coal conveying bucket 41 to rise or fall, so as to avoid the continuous replacement of the friction pad, reduce the transportation cost and simplify the transportation process.

[0050] Figure 3 is Figure 2 The structure diagram of the moving assembly in the embodiment, combined with Figure 3 Optionally, the moving assembly 2 comprises a moving trolley 22 and two guide wheels 23. The two guide wheels 23 are respectively located at both ends of the moving direction of the moving trolley 22, and are respectively connected with the moving trolley 22 in rotation, and the rotation axis of the guide wheel 23 is perpendicular to the moving direction of the moving trolley 22. The two guide wheels 23 correspond to the two traction ropes 31 one by one, and the end of each traction rope 31 away from the connected coal conveying bucket 41 is wound outside the corresponding guide wheel 23, and the traction rope 31 wound outside the guide wheel 23 spans at least half the circumference of the guide wheel 23, and the end of the traction rope 31 wound outside the guide wheel 23 is fixed.

[0051] In the embodiment of the present disclosure, the connecting frame 34 is arranged at the track assembly 1. The connecting frame 34 is fixed with the track assembly 1 or is fixed in the use site of the lifting transportation device. The end of each traction rope 31 away from the connected coal conveying bucket 41 is fixedly connected on the connecting frame 34 through a lock buckle. Then each traction rope 31 is wound on the top of the corresponding guide wheel 23 along the bottom of the guide wheel 23, and is connected with the coal conveying bucket 41 through the pulley block 33.

[0052] In the above implementation, the moving trolley 22 is used to move along the length direction of the track assembly 1. The guide wheels 23 are used to be connected with the two traction ropes 31, so as to move with the corresponding traction ropes 31 while following the movement of the guide wheels 23, so as to drive the coal bucket 41 to move up and down.

[0053] Moreover, since the traction ropes 31 wound outside the guide wheels 23 span at least half of the circumference of the guide wheels 23, the ends of the traction ropes 31 wound outside the guide wheels 23 are fixed, so the guide wheels 23 are essentially moving pulleys. Thus, by arranging the guide wheels 23 at the two ends of the moving trolley 22 respectively, the moving distance of the moving trolley 22 can be halved through the guide wheels 23, so as to reduce the moving distance of the moving trolley 22, and further reduce the length of the track assembly 1, so that the volume of the lifting and transporting device is greatly reduced.

[0054] That is, by arranging the guide wheels 23 at the front and rear ends of the moving trolley 22 respectively, a two-fold relationship is formed between the two traction ropes 31 and the moving trolley 22. That is, the speed of the traction ropes 31 is twice that of the moving trolley 22, but the driving force required for the moving trolley 22 to drive the coal bucket 41 to move up and down is twice the difference in load of the two traction ropes 31 to lift the coal bucket 41, and the stroke of the moving trolley 22 is half that of the coal bucket 41.

[0055] When the moving trolley 22 moves towards the left side of the Figure 1 , the traction rope 31 located at the left side of the moving trolley 22 drives the connected coal bucket 41 to move downward, while the traction rope 31 located at the right side drives the connected coal bucket 41 to move upward. When the moving trolley 22 moves towards the right side of the Figure 1 , the traction rope 31 located at the left side of the moving trolley 22 drives the connected coal bucket 41 to move upward, while the traction rope 31 located at the right side drives the connected coal bucket 41 to move downward.

[0056] For example, the net weight of the coal bucket itself is 150 tons, the rated coal loading is 150 tons, and the weight of the counterweight rope 40 in the lifting height range is 50 tons. When the coal is transported, the two coal buckets 41 are counterweighted, and only one coal bucket 41 is in the coal loading state. Therefore, the tension of one traction rope 31 for lifting the coal bucket 41 is about 350 tons, and the tension of the other traction rope 31 for lowering the coal bucket 41 is about 200 tons. The load difference between the two traction ropes 31 is 150 tons, that is, the weight of the coal. However, due to the ratio, the moving assembly 2 needs to provide a driving force of 300 tons. Due to the large production capacity requirement of the underground coal mine, the lifting speed of the coal bucket 41 is very fast, which can reach 18 m / s at the maximum, and the moving speed of the moving assembly 2 is 9 m / s (due to the ratio), that is, the moving assembly 2 needs to provide a horizontal driving force of 300 tons at a speed of 9 m / s. The lifting stroke of the coal bucket 41 is 700 meters, and the stroke of the moving trolley 22 is 350 meters.

[0057] In the embodiment, the pulley block 33 includes four pulley units 330, two of which are respectively located at both ends of the length direction of the track assembly 1 and are fixed on the ground through a support. The other two pulley units 330 are respectively located outside the shaft and at a position with a certain height from the ground. The two traction ropes 31 include a first traction rope 31a (located on the left side of the traction rope in the figure) and a second traction rope 31b (located on the right side of the traction rope in the figure). One end of the first traction rope 31a is connected with the left side of the track assembly 1, and the other end is wound out of the guide wheel 23 located on the left side, sequentially passes through one pulley unit 330 on the ground and one pulley unit 330 in the air, and is connected with the top of the coal bucket 41 located on the right side. One end of the second traction rope 31b is connected with the right side of the track assembly 1, and the other end is wound out of the guide wheel 23 located on the right side, sequentially passes through one pulley unit 330 on the ground and one pulley unit 330 in the air, and is connected with the top of the coal bucket 41 located on the left side. Figure 2 Figure 2 In other examples, the moving assembly 2 can be directly arranged as a moving trolley without arranging the guide wheel 23, but directly connecting the two traction ropes 31 with the front and rear ends of the moving trolley.

[0058] In the embodiment of the disclosure, each traction rope 31 is formed by a plurality of steel wire cables arranged side by side. Correspondingly, each pulley unit 330 includes a plurality of pulleys corresponding to the plurality of steel wire cables arranged side by side. Each steel wire cable is located in the guide groove of the corresponding pulley.

[0059]

[0060] Figure 4 is a left view of Figure 1 , combined with Figure 4 ​​Optionally, the track assembly 1 comprises two toothed rails 11, and the two toothed rails 11 are parallel to each other. The moving trolley 22 comprises two rows of driving pinions 222, and the two rows of driving pinions 222 correspond to the two toothed rails 11 in one-to-one correspondence. Each row of driving pinions 222 comprises a plurality of driving pinions 222, and each driving pinion 222 is engaged with the corresponding toothed rail 11.

[0061] In the above implementation manner, the toothed rail 11 is used for engaging with the driving pinion 222, so that when the driving pinion 222 rotates, the driving pinion 222 is engaged with the toothed rail 11, and then the driving pinion 222 can move along the toothed rail 11, so as to move the moving trolley 22.

[0062] Continuing to refer to Figure 4 Optionally, the track assembly 1 further comprises two wheel rails 12, and the two wheel rails 12 are parallel to the toothed rails 11. The moving trolley 22 further comprises two rows of walking wheels 223, and the two rows of walking wheels 223 correspond to the two wheel rails 12 in one-to-one correspondence. Each row of walking wheels 223 comprises a plurality of walking wheels 223, and at least part of each walking wheel 223 is movably located in the corresponding wheel rail 12.

[0063] In the above implementation manner, the wheel rail 12 is used for providing a track for the movement of the walking wheel 223, so that the walking wheel 223 can only walk along the length direction of the wheel rail 12. By arranging the walking wheel 223 in the moving trolley 22, the rolling of the walking wheel 223 in the wheel rail 12 can reduce the friction of the moving trolley 22 during movement, and facilitate the walking of the moving trolley 22.

[0064] Optionally, the moving trolley 22 further comprises a support body 221 and a driving unit 224. The plurality of driving pinions 222 and the plurality of walking wheels 223 are located at the bottom of the support body 221, and the plurality of driving pinions 222 and the plurality of walking wheels 223 are rotationally connected with the support body 221. The driving unit 224 is located in the support body 221 and connected with the plurality of driving pinions 222, so as to rotate the driving pinions 222.

[0065] In the above implementation manner, the toothed rail 11 is used for engaging with the driving pinion 222, so that when the driving pinion 222 rotates under the driving of the driving unit 224, the driving pinion 222 is engaged with the toothed rail 11, and then the driving pinion 222 can move along the toothed rail 11, thereby moving the moving trolley 22.

[0066] The support body 221 is used for being connected with the driving pinion 222 and the driving unit 224, so as to provide a mounting basis for the driving pinion 222 and the driving unit 224.

[0067] In this embodiment, the driving unit 224 includes a plurality of driving motors 2241, a plurality of gearboxes 2242 and a plurality of brakes 2243 arranged one-to-one corresponding to the driving pinions 222.

[0068] The driving motor 2241 is connected to the input end of the corresponding gearbox 2242, and the output end of the gearbox 2242 is connected to the corresponding driving pinion 222. The brake 2243 is connected to the corresponding driving motor 2241.

[0069] When the moving assembly 2 needs to move, the brake 2243 is opened, each driving motor 2241 is started, and the driving motor 2241 drives the corresponding driving pinion 222 to rotate through the corresponding gearbox 2242, and the driving pinion 222 moves along the rack rail 11 under the meshing with the rack rail 11. When the moving assembly 2 needs to be braked, the driving motor 2241 can be controlled to stop, and the brake 2243 is opened to brake the driving pinion 222.

[0070] In this embodiment, in a general underground coal mine, the net weight of the coal bucket itself is 150 tons, the rated coal loading is 150 tons, and the weight of the counterweight rope 40 in the lifting height range is 50 tons. When transporting coal, the two coal buckets 41 are counterweighted, and only one coal bucket 41 is in the coal loading state. Therefore, the tension of one traction rope 31 for lifting the coal bucket 41 is about 350 tons, and the tension of the other traction rope for lifting the coal bucket 41 is about 200 tons. The load difference between the two traction ropes 31 is 150 tons, that is, the weight of the coal. However, due to the magnification, the moving assembly 2 needs to provide a driving force of 300 tons.

[0071] Due to the large production capacity requirement of the underground coal mine, the lifting speed of the coal bucket 41 is very fast, and the maximum can reach 18 m / s, and the corresponding moving speed of the moving assembly 2 is 9 m / s (due to the magnification), that is, the moving assembly 2 needs to provide a horizontal driving force of 300 tons at a speed of 9 m / s. Since the lifting stroke of the coal bucket 41 is 700 meters, the stroke of the moving assembly 2 is 350 meters, although the guide wheel 23 reduces the stroke of the moving trolley 22, but the 350-meter-long stroke is difficult to be reliably realized by the conventional driving mechanism, and the gear and rack is the first choice due to the long stroke and large load. However, due to the manufacturing process, the gear engagement speed in general engineering is relatively low, and it is difficult to reach the engagement speed of 9 m / s, so high-speed gear and rack engagement mechanisms are rarely seen in coal mines. However, the train with a speed of 11 m / s on the railway has been successfully developed, which is a train that obtains high-speed movement by gear and rack transmission. The high-speed gear and rack engagement mechanism in the railway industry is applied to the underground coal mine in the embodiment of the present disclosure, that is, the toothed rail 11, the wheel rail 12, the driving pinion 222 and the walking wheel 223 are used to realize the high-speed and long-stroke walking of the moving assembly 2.

[0072] Furthermore, since the mobile trolley 22 requires a total driving force of 300 tons, and each driving pinion 222 provides approximately 25 tons of driving force, in this embodiment, there are 12 driving units 224 and 12 driving pinions 222. That is, there are 6 driving pinions 222 meshing with each toothed rail 11. Calculations show that its strength and lifespan meet the requirements.

[0073] The structure of the traveling wheels 223 is similar to that of train wheels, with 3 sets on each rail 12, for a total of 6 sets of traveling wheels. The traveling wheels 223 roll at high speed on the rail 12, driving the entire moving trolley 22 to move horizontally. To improve the stability of the moving trolley 22, each set of traveling wheels 223 is located between two adjacent drive pinions 222 along the length of the rail 12.

[0074] In this embodiment, the cross-section and specifications of the wheel rail 12 refer to the structural form of a train track. The toothed rail 11 has single-sided teeth, with the tooth surface facing the drive pinion 222. The installation of the toothed rail 11 and the wheel rail 12 is similar to that of a train track. First, a foundation (including sleepers, gravel, etc. for the track) needs to be laid, and then the track is connected to the foundation using movable fasteners or fasteners.

[0075] Optionally, the two toothed rails 11 are located between the two wheel rails 12. This places the traveling wheels 223 on both sides of the support body 221 to provide stable support for the support body 221, so that the moving trolley 22 will not shake but remain stable when moving.

[0076] In this embodiment, the bottom of the support 221 has a cavity 2210 for accommodating the drive unit 224.

[0077] Figure 5 yes Figure 1 Top view, combined Figure 5 Optionally, the lifting and transporting device also includes a telescopic assembly 5, which includes a support unit 51 and two telescopic units 52. The support unit 51 is located outside the track assembly 1, and the two telescopic units 52 are located at both ends of the moving direction of the moving assembly 2 and are connected to the support unit 51. The two telescopic units 52 correspond one-to-one with the two traction ropes 31.

[0078] Each telescopic unit 52 is located at the bottom of the corresponding traction rope 31 and contacts the corresponding traction rope 31 to support the traction rope 31. Each telescopic unit 52 can move along the length direction of the track assembly 1 as the contacted traction rope 31 moves. Figure 2 a) Stretch or contraction in the direction of the middle.

[0079] In the above implementation, the telescopic component 5 is used to support the traction rope 31 to prevent the traction rope 31 from sagging and affecting the lifting of the coal skip 41. The support unit 51 provides an installation base for the telescopic unit 52, which in turn supports the corresponding traction rope 31 to prevent it from sagging.

[0080] Because the horizontal movement distance of the moving trolley 22 is relatively long, the length of the traction rope 31 wound on the guide wheels 23 at both ends of the moving trolley 22 is constantly changing. When the length of the traction rope 31 is long, the traction rope 31 will sag like an electric wire due to its own weight. The longer the length, the more serious the sag. Therefore, the middle part of the traction rope 31 needs to be supported.

[0081] Since the telescopic unit 52 can extend and retract along the length of the track assembly 1 as the contacting traction rope 31 moves, the telescopic unit 52 will not interfere with the moving trolley 22 due to its movement, while simultaneously supporting the traction rope 31 to prevent it from sagging. In other words, the telescopic unit 52 can support the traction rope 31 and extend and retract with the moving assembly 2 without hindering its operation.

[0082] The support unit 51 mentioned above is located outside the track assembly 1, meaning that the support unit 51 is located outside the two toothed rails 11 and outside the two wheel rails 12 in the track assembly 1. In this embodiment, the two toothed rails 11 and the two wheel rails 12 are located on the ground, and the support unit 51 is located above the track assembly 1.

[0083] Figure 6 yes Figure 5 Enlarged view at point C, combined with Figure 6 Optionally, the support unit 51 includes two guide rails 511 and a plurality of support arms 512. The two guide rails 511 are parallel to each other and located on one side of the track assembly 1 along a direction perpendicular to the length direction of the track assembly 1. The length direction of each of the two guide rails 511 is the same as the length direction of the track assembly 1.

[0084] Two sets of support arms 512 correspond one-to-one with two guide rails 511. Each set of support arms 512 includes multiple support arms 512. The multiple support arms 512 in the same set are connected at intervals along the length direction of the guide rail 511 on the side of the corresponding guide rail 511 facing the track assembly 1. The support arms 512 intersect with the planes where the two guide rails 511 are located.

[0085] Combination Figure 6 The plane containing the two guide rails 511 is the same plane as the paper. The support arm 512 is located on one side of the plane containing the paper, and the length direction of the support arm 512 is perpendicular to the paper or intersects the paper.

[0086] In the above implementation, the guide rail 511 is used to provide a mounting base for the telescopic movement of the telescopic unit 52, and the support arm 512 is used to support the guide rail 511 so that the guide rail 511 can be suspended above the track assembly 1 and be separated from the ground.

[0087] Figure 7 is Figure 2 In the above implementation, the support arm 512 is connected to the guide rail 511 perpendicularly, and the support arm 512 is used to support the guide rail 511. One end of the support arm 512 is welded or bolted to the guide rail 511, and the other end is fixed to the ground. Figure 7

[0088] In the above implementation, the telescopic unit 52 includes a plurality of sliding members 521 and a plurality of hinged members 522. The plurality of sliding members 521 are located between two guide rails 511 along the length direction of the guide rail 511, and each sliding member 521 is connected to two guide rails 511 at both ends thereof. Each sliding member 521 is in contact with a traction rope 31 and supports the traction rope 31. Figure 5 Figure 6 is

[0089] In the above implementation, each hinged member 522 of the plurality of hinged members 522 is located between two adjacent sliding members 521 and is hinged to the two adjacent sliding members 521 to change the distance between the two adjacent sliding members 521. Figure 8 Figure 2 Figure 8 In the above implementation, since one hinged member 522 is arranged between two adjacent sliding members 521, when the moving assembly 2 moves, the sliding member 521 follows the movement, and the hinged member 522 hinged to the sliding member 521 pushes the other adjacent sliding member 521 to move and form a relay, and finally all the sliding members 521 are retracted into a gathered state or stretched into an elongated state.

[0090] In the above implementation, the plurality of sliding members 521 includes a first sliding member 5211, a plurality of second sliding members 5212, and a third sliding member 5213. The plurality of second sliding members 5212 is located between the first sliding member 5211 and the third sliding member 5213, and the third sliding member 5213 is located between the first sliding member 5211 and the moving assembly 2. The first sliding member 5211 is connected to the track assembly 1, the third sliding member 5213 is connected to the moving assembly 2, and the plurality of second sliding members 5212 and the third sliding member 5213 can move close to or away from the first sliding member 5211.

[0091] In the above implementation, the plurality of sliding members 521 includes a first sliding member 5211, a plurality of second sliding members 5212, and a third sliding member 5213. The plurality of second sliding members 5212 is located between the first sliding member 5211 and the third sliding member 5213, and the third sliding member 5213 is located between the first sliding member 5211 and the moving assembly 2. The first sliding member 5211 is connected to the track assembly 1, the third sliding member 5213 is connected to the moving assembly 2, and the plurality of second sliding members 5212 and the third sliding member 5213 can move close to or away from the first sliding member 5211.

[0092] ​​​Since the first sliding member 5211 is connected with the track assembly 1, and the third sliding member 5213 is connected with the moving assembly 2, the first sliding member 5211 is fixed and cannot move. The second sliding member 5212 and the third sliding member 5213 can move relative to the first sliding member 5211. Therefore, when the moving assembly 2 moves, the third sliding member 5213 will move synchronously and in the same direction with the moving assembly 2.

[0093] Since a hinged member 522 is arranged between two adjacent sliding members 521, when the third sliding member 5213 moves, the hinged member 522 connected with the third sliding member 5213 will push the adjacent second sliding member 5212, forming a relay, and finally retracting all the sliding members 521 into the gathered state or stretching into the elongated state.

[0094] In combination Figure 3 In order to facilitate the connection between the third sliding member 5213 and the moving assembly 2, the moving assembly 2 is provided with a connecting member 231 at both ends of the moving direction, the connecting member 231 is connected with the nearest guide wheel 23, and the connecting member 231 is connected with the third sliding member 5213 in the adjacent telescopic unit 52.

[0095] In combination Figure 4 Optionally, each sliding member 521 includes a sliding rod 5001 and two guide blocks 5002. The two guide blocks 5002 are connected with both ends of the length direction of the sliding rod 5001, and each guide block 5002 of the two guide blocks 5002 is located in a guide rail 511 and in sliding contact with the guide rail 511. The outer wall of the sliding rod 5001 close to the guide block 5002 is hinged with the adjacent hinged member 522.

[0096] In the above implementation manner, the sliding rod 5001 is used to support the traction rope 31 and provide a mounting basis for the guide block 5002. The guide block 5002 is used to cooperate with the guide rail 511, so that the sliding member 521 can only move along the length direction of the guide rail 511.

[0097] Moreover, the guide block 5002 is used to be hinged with the hinged member 522, so that the adjacent two sliding members 521 are telescopically connected together.

[0098] In combination Figure 4 For example, when the moving assembly 2 moves to the left, the third sliding member 5213 in the left telescopic unit 52 is driven by the moving assembly 2 to move to the left, and the guide block 5002 in the third sliding member 5213 will push the adjacent guide block 5002, forming a relay, and finally retracting the left sliding member 521 into the gathered state.

[0099] Meanwhile, in the right telescopic unit 52, the moving assembly 2 pulls the right third sliding member 5213 to move left, under the pulling effect of the hinge member 522, the sliding members 521 and the corresponding guide blocks 5002 are pulled apart from each other, and the right sliding member 521 is in an elongated state.

[0100] Although the distances between the sliding members 521 are not necessarily the same during the movement, the maximum distance between the sliding members 521 is determined due to the connection of the hinge member 522, so that the traction rope 31 can be effectively lifted and supported to prevent sagging.

[0101] In combination Figure 4 Optionally, the sliding member 521 further comprises a roller 5003 coaxially sleeved on the middle portion of the sliding rod 5001 and rotationally connected with the sliding rod 5001, and the outer wall of the roller 5003 is in contact with the traction rope 31.

[0102] In the above implementation, the roller 5003 rolls relative to the sliding rod 5001, which acts like a bearing to support the traction rope 31, and can reduce the friction between the traction rope 31 and the sliding member 521.

[0103] Figure 9 In combination Figure 4 In combination Figure 9 In this embodiment, the inside of each guide rail 511 has a guide groove 510, and the guide groove 510 is long strip-shaped, and the length direction of the guide groove 510 is the length direction of the guide rail 511. The guide block 5002 is a rectangular block, and the guide block 5002 is connected with the end portion of the sliding rod 5001 through threads. The guide block 5002 is located in the guide groove 510 and is in contact with the groove wall of the guide groove 510 to form a sliding friction pair.

[0104] Figure 10 In combination Figure 2 In combination Figure 11 In combination Figure 10 In combination Figure 10 and Figure 11 The groove wall of the guide groove 510 is provided with a sliding surface 5110 with a small friction coefficient, and the sliding surface 5110 is made of copper-based alloy material or high polymer material.

[0105] In combination Figure 9Optionally, the sliding member 521 further comprises two baffle plates 5004, which are respectively connected to the two ends of the sliding rod 5001 and correspond to the two guide blocks 5002. Each baffle plate 5004 is located on the side of the corresponding guide block 5002 facing the other guide block 5002 and is spaced from the corresponding guide block 5002. The hinged member 522 is located between the guide block 5002 and the corresponding baffle plate 5004.

[0106] The baffle plate 5004 can limit the hinged member 522 and the hinged part of the sliding member 521 between the guide block 5002 and the corresponding baffle plate 5004, preventing the hinged member 522 from interfering with the intermediate traction rope in space.

[0107] In the embodiment, the baffle plate 5004 is a circular ring structure and is welded with the sliding rod 5001.

[0108] Referring to Figure 8 Optionally, the hinged member 522 comprises two hinged arms 5220 hinged with each other and respectively hinged with the adjacent two sliding members 521.

[0109] In the above implementation, the hinged arm 5220 is used to hinge the adjacent two sliding members 521 together.

[0110] That is, each hinged member 522 comprises Figure 8 As shown, the first hinged arm (the hinged arm on the left side) and the second hinged arm (the hinged arm on the right side) are located, one end of the first hinged arm is hinged with one of the adjacent two sliding members 521, the other end of the first hinged arm is hinged with one end of the second hinged arm, and the other end of the second hinged arm is hinged with the other of the adjacent two sliding members 521.

[0111] Figure 12 is a structural schematic view of the hinged arm, in combination with Figure 12 In the embodiment, the hinged arm 5220 is a steel wire rope joint, and the hinged arm 5220 comprises a steel wire rope 5221 and two shackles 5222. The two shackles 5222 are respectively connected to the two ends of the steel wire rope 5221 and are respectively hinged with the other hinged arm 5220 adjacent to the hinged arm 5220 and the sliding member 521.

[0112] Among the two shackles 5222, one is a male pin hole and the other is a female pin hole. Since the steel wire rope joint has a certain hardness, when a plurality of steel wire rope joints are contracted together, they will not be entangled with each other and cannot be separated.

[0113] The working process of the lifting and transporting device provided by the embodiment of the present disclosure will be briefly introduced as follows:

[0114] The initial state is that the coal bucket 41 on the right is on the ground in the unloading state, and the coal bucket 41 on the left is at the bottom of the shaft in the loading state. The moving assembly 2 is at the leftmost side of the track assembly 1, and the brake 2243 of each drive unit 224 is in the braking state.

[0115] When the coal in the coal bucket 41 on the right has been completely unloaded and needs to be lowered, and the coal in the coal bucket 41 on the left has been completely loaded and needs to be lifted, each brake 2243 in the drive unit 224 in the moving assembly 2 is opened, the drive motor 2241 is started, the drive pinion 222 is engaged with the rack rail 11 of the track assembly 1 to drive the entire moving trolley 22 to roll on the wheel rail 12 and move to the right. The left traction rope 31 is lifted to move the left coal bucket 41 upward, and at the same time, the right traction rope 31 is lifted to move the right coal bucket 41 downward. The left telescopic unit 52 gradually changes from the gathering state to the elongated state to effectively support the traction rope 31, and the right telescopic unit 52 gradually changes from the elongated state to the gathering state. In the final state, the left coal bucket 41 is lifted above the ground, and the right coal bucket 41 is lowered into the well.

[0116] When the coal in the coal bucket 41 on the right is loaded, and the coal in the coal bucket 41 on the left is unloaded, the next step of lifting is needed, the moving assembly 2 only needs to move in the opposite direction (to the left), and the specific process will not be repeated.

[0117] In the embodiments of the present disclosure, the moving assembly 2 continuously moves back and forth horizontally on the track assembly 1 to convert the horizontal movement into the vertical lifting movement of the coal bucket 41, so as to realize the rapid mining and transportation of coal underground.

[0118] The above only describes optional embodiments of the present disclosure, and does not limit the present disclosure. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present disclosure shall be included in the protection scope of the present disclosure.
