Description

Technical Field

[0001] This invention relates to the field of mining machinery and equipment technology, specifically to a hoisting mechanism for installing mining machinery and equipment. Background Technology

[0002] Mining machinery and equipment refers to machinery specifically used for mining, mineral processing, and prospecting. A large number of cranes, conveyors, ventilators, and drainage machinery used in mining operations are collectively referred to as mining machinery and equipment.

[0003] Currently, the installation of existing underground mining machinery requires moving the equipment to a designated installation location in the mine tunnel before installation. When installing centrifugal multistage water pumps, which are long and heavy, multiple workers are needed to move them. This manual handling is not only time-consuming, but the uneven surface of the mine tunnel also increases the difficulty of moving the centrifugal multistage water pumps. Furthermore, the pumps are prone to collisions with the tunnel during handling, affecting their service life.

[0004] Although the existing patent application number CN202110479833.0 discloses a hoisting mechanism for mining equipment, relating to the field of mining equipment technology, including a support column, a connecting beam fixedly connected to the top of the support column, and an annular slide rail fixedly connected to the bottom of the connecting beam; however, when this hoisting mechanism moves along the inside of the tunnel to hoist a centrifugal multistage water pump, the motor end of the centrifugal multistage water pump is relatively heavy, so the hoisting mechanism cannot guarantee the stability of the centrifugal multistage water pump during the hoisting process.

Detailed Implementation

[0044] 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.

[0045] Please see Figure 1-4 Example 1

[0046] A hoisting mechanism for installing mining machinery includes a hoisting guide rail 1 installed inside a mine tunnel. The hoisting guide rail 1 is installed at the top of the mine tunnel and serves to support a traveling mechanism 2. The traveling mechanism 2 is located on the outer side of the hoisting guide rail 1, and a support base 3 is connected to the bottom of the traveling mechanism 2. In this invention, the hoisting guide rail 1 is I-shaped, and the traveling mechanism 2 consists of traveling wheels that are respectively rolled and connected to concave grooves on both sides of the hoisting mechanism. Both traveling wheels are existing electrically controlled, enabling them to move along the hoisting guide rail 1. Both traveling wheels are mounted on the support base 3, and a connecting mechanism 4 is installed at the bottom of the support base 3. The bottom of the connecting mechanism 4 is connected to a support plate 41. The connecting mechanism 4 includes four winding wheels 42 located below the support base 3, and a rotating shaft is fixedly inserted through the axis of each of the four winding wheels 42. A base plate is installed at the bottom of the rotating shaft 43 and the support base 3 to support the rotating shaft 43. The rotating shaft 43 is rotatably connected to the base plate. A traction chain 44 is wound around the outside of the winding reel 42. One end of the traction chain 44 is connected to the support plate 41 by a buckle. A first helical gear 45 is fixedly connected to one end of the rotating shaft 43. A second helical gear 46 is meshed with the outside of the first helical gear 45. A transmission shaft 47 is fixedly connected to the second helical gear 46. The transmission shaft 47 is rotatably connected to the support base 3 through a bearing seat. A transmission gear 48 is fixedly connected to the top of the rotating shaft. Multiple transmission gears 48 are connected to each other by an internal gear ring 49. The internal gear ring 49 is rotatably connected to the bottom of the support base 3 through a bearing seat. A transmission motor (not shown in the figure) is installed on the support base 3 to drive one of the transmission gears 48.

[0047] Specific implementation process: When the support height of the support plate 41 is adjusted, the drive motor runs, which causes one of the drive gears 48 to rotate synchronously under the transmission of the inner gear ring 49. Under the transmission of the first helical gear 45 and the second helical gear 46, multiple winding wheels 42 are further used to simultaneously wind or unwind the traction chain 44. Before hoisting the centrifugal multistage water pump, the traction chain 44 is adjusted to the lowest height of the support plate 41. After the centrifugal multistage water pump is fixed, the traction chain 44 is wound up to lift the water pump. At the same time, the centrifugal multistage water pump moves along the inside of the mine tunnel under the drive of the walking mechanism.

[0048] An adjustment and locking mechanism 5 is installed at the bottom of the support plate 41, and a lifting frame 6 is connected to the adjustment and locking mechanism 5. The lifting frame 6 is inverted U-shaped, and both ends of the lifting frame 6 are fixedly connected to the lifting shell 71. The lifting frame 6 is provided with a fixing mechanism 7 for fixing the centrifugal multistage water pump. After the centrifugal multistage water pump is fixed, the adjustment and locking mechanism 5 adjusts the stability of the support plate 41.

[0049] The fixing mechanism 7 includes a lifting shell 71 fixedly installed at the bottom of the lifting frame 6. The bottom of the lifting shell 71 is connected to a moving mechanism 72, and two moving shells 73 are connected to the moving mechanism 72.

[0050] The bottom of the movable housing 73 is equipped with a clamping component 74, and the hoisting housing 71 is provided with a synchronizing component 75 for synchronously driving the two clamping components 74.

[0051] The moving mechanism 72 includes two first bidirectional threaded screws 721 rotatably connected to the bottom of the hoisting shell 71. One end of the two first bidirectional threaded screws 721 located outside the hoisting shell 71 is fixedly connected to a drive gear 722. The two drive gears 722 are connected to each other by a drive gear chain 723. A handle 724 is installed on one of the drive gears 722.

[0052] Two first bidirectional threaded screws 721 are rotatably sleeved with two moving blocks 725 on their outer sides, and the two moving blocks 725 are respectively fixedly connected to two moving shells 73.

[0053] The clamping member 74 includes a second bidirectional threaded screw 741 rotatably connected inside the movable housing 73, and one end of the second bidirectional threaded screw 741 located outside the movable housing 73 is connected to the synchronizing member 75.

[0054] The second bidirectional threaded screw 741 has two clamping plates 742 threadedly sleeved on its outer side. The clamping plates 742 are provided with anti-slip pads on their outer sides. The clamping plates 742 can not only stably clamp the centrifugal multistage water pump, but also prevent the water pump from slipping. Both clamping plates 742 are slidably connected to the movable housing 73. The bottom of the clamping plates 742 is arc-shaped. The four clamping plates 742 are located at both ends of the centrifugal multistage water pump and are fixed to it.

[0055] The synchronizing component 75 includes connecting gears 751 that are fixedly connected to one end of the two second bidirectional threaded screws 741 located on the outside of the movable housing 73. A connecting gear chain 752 is connected between the two connecting gears 751. A synchronizing gear 753 is connected to the inner side of the connecting gear chain 752. A drive motor 754 is provided on the outside of the hoisting housing 71, and the output end of the drive motor 754 is fixedly connected to the synchronizing gear 753 through a coupling.

[0056] A fixing block 755 is installed on the outside of the drive motor 754, and a positioning component 76 for adjusting the fixed height of the fixing block 755 is installed on the hoisting housing 71.

[0057] The positioning component 76 includes a lifting port provided on the hoisting housing 71, and a lifting screw 761 is rotatably connected to the lifting port. A rotating handle 762 is installed at one end of the lifting screw 761 located at the bottom of the hoisting housing 71. A fixing block 755 is threaded onto the outside of the lifting screw 761 and is slidably connected to the lifting port.

[0058] Specific implementation process: Before hoisting the centrifugal multistage water pump, the centrifugal multistage water pump is moved to the mine tunnel entrance by a mobile vehicle. At this time, the centrifugal multistage water pump is located on the ground at the mine tunnel entrance. Then, the hoisting shell 71 is moved to directly above the centrifugal multistage water pump. Subsequently, the two first bidirectional threaded screws 721 are rotated synchronously by the manual handle 724, and driven in opposite directions by the two moving blocks 725 respectively. Due to the limitation of the two first bidirectional threaded screws 721, the two moving blocks 725 are further moved towards each other or in opposite directions. The two sets of clamping plates 742 are further adjusted to move to both ends of the centrifugal multistage water pump respectively.

[0059] After the distance between the two movable housings 73 is adjusted, the handle 762 can be manually turned to make the lifting screw 761 rotate at the lifting port and provide driving force to the fixing block 755. Under the limit of the lifting port, the fixing block 755 further moves the synchronous gear 753 on it in the vertical direction until the connecting gear 751 chain is adjusted and tightened. Then, by running the drive motor 754, the two second bidirectional threaded screws 741 are further rotated relative to the inside of the movable housing 73, and provide driving force in opposite directions to the two clamping plates 742, so that the four clamping plates 742 located at both ends of the centrifugal multistage water pump move towards each other until the centrifugal multistage water pump is clamped and fixed. In this application, the centrifugal multistage water pump is lifted by clamping, and there is no need for manual handling of the water pump. At the same time, the water pump is stably lifted and protected during lifting.

[0060] The adjusting locking mechanism 5 includes two side plates 51 fixedly connected to the bottom of the support plate 41. Support rods 52 are fixedly connected to the side of the two side plates 51 that are close to each other. Two connecting brackets 53 are fixedly connected between the two support rods 52, and the support rods 52 are slidably connected to the bottom of the hoisting frame 6.

[0061] One end of one of the support rods 52 is fixedly connected to a transmission limiting mechanism 8, and the transmission limiting mechanism 8 is connected to the hoisting shell 71;

[0062] Both support rods 52 are provided with telescopic fixing parts 54 on their outer sides, and the telescopic fixing parts 54 connect the support plate 41 to the hoisting shell 71. The telescopic fixing parts 54 include a positioning sleeve 541 fixedly connected to the bottom of the support plate 41. A positioning rod 542 is slidably connected inside the positioning sleeve 541, and one end of the positioning rod 542 is connected to a T-shaped end 543 inside the positioning sleeve 541. A locking part 9 is provided at the T-shaped end 543 to lock the positioning rod 542 and the positioning sleeve 541.

[0063] A positioning spring 544 is sleeved on the outside of the positioning rod 542. The top of the positioning spring 544 is fixedly connected to the T-shaped end 543, and an annular plate 545 is fixedly connected to the bottom of the positioning spring 544. A pressure sensor 546 is installed at the bottom of the annular plate 545, and the pressure sensor 546 is fixedly connected to the bottom end inside the positioning sleeve 541.

[0064] The hoisting frame 6 is provided with a movable opening for the positioning rod 542 to pass through. A limiting ring 547 is fixedly connected to the outside of the positioning rod 542 and the limiting ring 547 is located on the movable opening. A rolling rod 548 is fixedly connected to the bottom of the positioning rod 542 and the rolling rod 548 is slidably connected between the hoisting frame 6 and the hoisting shell 71.

[0065] The transmission limiting mechanism 8 includes a limiting motor 81 fixedly connected to one end of one of the support rods 52. A limiting gear 82 is fixedly connected to the output end of the limiting motor 81. A gear rack 83 is meshed with the outer side of the limiting gear 82. A certain gap exists between the gear rack 83 and the limiting gear 82, allowing the gear rack 83 to rotate a certain angle relative to the limiting gear 82 as the hoisting shell 71 rotates. Simultaneously, the limiting gear 82 also limits the movement of the hoisting shell 71, preventing it from sliding relative to the support rod 52 after tilting. Please refer to [reference needed]. Figure 13 The top of the hoisting housing 71 is provided with a groove, and the bottom of the gear rack 83 is installed inside the groove. The top of the gear rack 83 and the top of the hoisting housing 71 are on the same plane.

[0066] The locking component 9 includes a movable groove provided at the T-shaped end 543, and an electric push rod 91 is fixedly connected inside the movable groove. A locking block 92 is fixedly connected to the output end of the electric push rod 91, and two wedge blocks 93 are slidably connected to the outside of the locking block 92. A snap-fit ​​rod 94 is fixedly connected to the ends of the two wedge blocks 93 that are far apart from each other. At the same time, when the elastic force of the positioning spring 544 and the T-shaped end 543 are in a state of mutual balance, the limiting ring 547 is located at the movable opening. At this time, the snap-fit ​​block 95 is located at the snap-fit ​​groove position.

[0067] The T-shaped end 543 has a guide groove inside for limiting the locking rod 94. The locking rod 94 is fixedly connected to a locking block 95 at one end inside the guide groove. The positioning sleeve 541 has two locking grooves inside. A locking spring 96 is sleeved on the outside of the locking rod 94, and the two ends of the locking spring 96 are fixedly connected to the locking block 95 and one end of the inner wall of the guide groove, respectively.

[0068] Specific implementation process: After clamping the centrifugal multistage water pump, it is lifted by the connecting mechanism 4. Since the motor end of the centrifugal multistage water pump is relatively heavy, the electric push rods 91 inside the two positioning sleeves 541 are in a retracted state, meaning the two locking rods 94 are disengaged from the locking grooves. At this time, the positioning rods 542 and the positioning sleeves 541 maintain relative sliding. When the weight of one end of the lifting shell 71 is relatively large, the lifting shell 71 rotates relative to the support rod 52. Simultaneously, the positioning rods 542 at both ends of the support rod 52 move relative to the positioning sleeves 541. When one of the pressure sensors 546 detects an increase in pressure, the limit motor... When 81 is in operation, the limiting gear 82 drives the heavier end of the hoisting shell 71 to move along the direction of the support rod 52 through the gear rack 83 until the pressure values ​​detected by the two pressure sensors 546 are the same. Then, the limiting plates of the two side plates 51, the two positioning rods 542 and the positioning sleeve 541 form an initial height. At this time, the two electric push rods 91 are in operation, which further causes the locking block 95 at the positioning rod 542 to engage with the locking groove, thereby locking the positioning rod 542 and the positioning sleeve 541. This further supports the hoisting frame 6 with the support rod 52 and the two positioning rods 542. At this time, the centrifugal multistage water pump can move along the inside of the mine tunnel to the installation position through the walking mechanism 2.

A rotating ring 10 is installed at one end of the second bidirectional threaded screw 741 located outside the movable housing 73. By manually rotating the two rotating rings 10, the second bidirectional threaded screw 741 is further rotated inside the movable housing 73. Driven by the clamping plates 742, and under the limitation of the movable housing 73, the two clamping plates 742 move towards each other until the centrifugal multistage water pump is clamped and fixed. In this embodiment, the distance between the two clamping plates 742 is adjusted manually.
