Description

Technical Field

[0001] This application relates to the technical field of belt conveyors, and specifically relates to a belt conveyor drive connection device. Background Art

[0002] The belt conveyor for coal mines, also known as the belt conveyor for coal mines, is a key mechanical equipment for material transportation by belt widely used in the coal mining industry, and undertakes the task of transporting materials such as coal. It consists of multiple components, including a drive device, a belt, conveyor rollers, a tensioning device, a support device, etc. These components work together to achieve continuous transportation of materials from one place to another. The belt conveyor for coal mines has the advantages of long-distance continuous transportation, large transportation capacity, flexible layout, durability and reliability.

[0003] The drive device of the belt conveyor for coal mines mainly consists of a motor, a coupling or a hydraulic coupling, a reducer, a driving drum, etc. These components work together to transmit the power of the motor to the driving drum, and then drive the belt to move. Specifically, when it works, the motor transmits the power to the driving drum through the reducer and the coupling, and the driving drum transmits the power to the belt by means of the friction between its surface and the belt, so that the belt moves and transports materials. During the transportation process, the tensioning device is used to adjust the tension of the belt to ensure the stability and safety of transportation; the support device is used to support the conveyor rollers and the belt to keep it running smoothly.

Detailed Embodiment

[0023] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "vertical", "horizontal", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0024] In order to better understand the technical solution of the present application, the above technical solution will be described in detail below in conjunction with the specification drawings and specific embodiments.

[0025] In order to solve the technical problem that the existing motor drive connection seat cannot adapt to motors of different specifications and sizes according to actual working requirements, this example discloses a belt conveyor drive connection device, see Figure 1 .

[0026] The belt conveyor drive connection device includes an L-shaped seat body 1, which is made of steel and includes a bottom plate 11 and a vertical plate 12 arranged perpendicularly to each other. The bottom plate 11 is used to directly or indirectly contact the working ground to ensure the stability of the seat body 1 after loading during operation. The vertical plate 12 is used to fix the drive motor, and the seat body 1 provides reliable support for the drive motor. In order to fix the drive motor at the vertical plate 12, see Figure 2 A driving through hole 21 is provided at the vertical plate 12. The diameter of the driving through hole 21 is larger than the maximum diameter of the shaft of the driving motor, and the center of the driving through hole 21 passes through the vertical center line of the vertical plate 12, so that the shaft of the driving motor can be passed through the driving through hole, thereby ensuring that the motor is fixed to the base 1 while the shaft can be connected to the coupling and the reducer. Since the end face of the driving motor is provided with a fixing flange, the corresponding Figure 2 The driving through hole 21 is provided with a plurality of mounting slots 21 in a circular array along the edge thereof. The mounting slots 21 are arranged along the radial direction of the driving through hole 21 , thereby being able to adapt to the fixing flanges of different diameters of different driving motors, and realizing the bolt connection and fixation between motors of different specifications and sizes and the seat body 1 .

[0027] In addition, considering that the vertical plate 12 is arranged perpendicular to the bottom plate 11, in order to ensure the vertical relationship between the two, and thus ensure the horizontality of the power shaft after the drive motor is connected and fixed to the vertical plate 12, in this embodiment, see Figure 2 Reinforcing ribs 13 are arranged between the bottom plate 11 and the vertical plates 12 on both sides of the seat body 1 .

[0028] However, considering that the drive motor has a certain weight, it is impossible to achieve a stable and reliable fixed setting by only relying on the connection between the fixing flange at the end of the drive motor and the seat plate 1 because the tail of the drive motor is suspended in the air. Therefore, in this embodiment, see Figure 1 The belt conveyor drive connection device also includes a seat plate 5 that moves along the slide groove driven by the slide member. The rear of the drive motor is supported by the movable and liftable seat plate 5, thereby ensuring the stability of the drive motor setting.

[0029] Considering that drive motors of different specifications and sizes vary in length, and after the end of the drive motor is fixedly connected to the flange of the seat body, there is a problem that the tail is suspended without support. However, in this embodiment, considering that if the support body for supporting the tail of the drive motor is designed to be too long, in the operating state of a small-sized drive motor, the overly long support body will affect the limited space in the mine. If it is set too short, it will be difficult to effectively support a large-sized drive motor. Therefore, in this embodiment, a seat plate 5 adjustable along the axial direction of the drive motor is provided, so as to adjust its support position according to drive motors of different sizes, thereby ensuring the stability and reliability of the installation of the drive motor.

[0030] Specifically, referring to Figure 1 and Figure 2 , to achieve the adjustability of the seat plate 5 along the axial direction of the drive motor, two chutes 3 symmetrical about the vertical central plane of the bottom plate 11 are provided on the top surface of the bottom plate 11 of the seat body 1. In this example, the chute is formed by welding two relatively arranged angle steels to the bottom plate 11, and a certain gap is left between the two angle steels to form a strip-shaped sliding hole 31. A sliding member is slidably fitted in the chute 3, and the seat plate 5 is driven to move along the axial direction of the drive motor by the sliding of the sliding member.

[0031] Referring to Figure 3 , the sliding member includes sliders 41 respectively slidably fitted in the two chutes 3. The sliders 41 are strip-shaped sliders and the outer edges thereof slidably fit with the inner edges of the chutes 3 correspondingly, so as to prevent the sliders 41 from shaking in the chutes 3 after being stressed, thereby ensuring the relative fixation of the position of the seat plate after adjustment and avoiding affecting the support stability effect of the seat plate on the drive motor. In order to realize the synchronous movement and adjustment of the two sliders 41, referring to Figure 3 , in this example, a connecting plate 43 is fixedly arranged between the two sliders 41, and the connecting plate 43 is arranged at the middle position of the two sliders 41. Considering that the strip-shaped sliding hole 31 of the chute 3 has a certain thickness, in order to prevent the connecting plate 43 from interfering with the chute wall in position and affecting the fitting of the slider 41 in the chute 3, the distance between the bottom surface of the connecting plate 43 and the top surface of the slider 41 is set to be not less than the thickness of the strip-shaped sliding hole 31. Specifically, in this embodiment, the connecting plate is fixedly connected to the slider 41 through a backing plate with a thickness greater than the thickness of the strip-shaped sliding hole 31.

[0032] In order to realize the adjustment of the position of the seat plate, that is, the adjustment of the position of the slider 41 relative to the chute 3, in this example, referring to Figure 3 , a displacement sleeve 62 is fixedly arranged at the middle position of the bottom of the connecting plate 43 parallel to the length direction of the slider 41. The displacement sleeve 62 is provided with internal threads inside, referring to Figure 1 , a displacement screw 61 is provided to match with the displacement sleeve 44, and referring to Figure 2The two ends of the bottom plate 11 of the seat body 1 are respectively fixedly connected with screw positioning plates 32, which are parallel to the bottom plate and coincide with the center line of the slide slot, and are used to relatively fix the displacement screw 61. Among them, a through hole for passing the displacement screw 61 is opened at the screw positioning plate 32, and a bearing is fixedly arranged in the hole, and the bearing is also fixedly connected to the displacement screw. Therefore, the two ends of the displacement screw 61 are relatively fixed to the seat body 1 through the bearings, and the displacement screw 61 is rotated relative to the seat body 1 through the bearings. Since the displacement sleeve 44 is threadedly connected to the displacement screw 61, when the displacement screw 61 rotates, the displacement sleeve 44 drives the connecting plate 43 to realize the forward and backward movement along the layout direction of the displacement screw 61.

[0033] Further, in order to achieve the purpose of adjusting the height position while the seat plate 5 moves with the connecting plate 43, see Figure 1 and Figure 3 An adjusting stud 44 is fixedly provided at the center position of the connecting plate 43, and correspondingly, an adjusting sleeve 51 is fixedly provided at the bottom center position of the seat plate 5, the adjusting sleeve 51 is slidably sleeved outside the adjusting stud 44, and an adjusting nut 53 is threadedly connected at the adjusting stud 44, and the end of the adjusting sleeve 51 abuts against the corresponding end surface of the adjusting nut 53, thereby changing the depth of the adjusting stud 44 embedded in the adjusting sleeve 51 by adjusting the height position of the adjusting nut 53 at the adjusting stud 44, that is, the height position of the seat plate 5 is adjusted by screwing the adjusting nut 53.

[0034] However, the adjusting sleeve 51 is only movably mounted on the adjusting stud 44. When the seat plate 5 is subjected to external force, it will rotate around the adjusting sleeve 51 as the center. Figure 3 , guide posts 42 are fixedly arranged at the top positions of both ends of the slider 41, and each guide post 42 is arranged perpendicular to the top surface of the slider. Figure 1 , guide sleeves 52 are fixedly arranged at the corresponding positions at the bottom of the seat plate 5, respectively, and are nested with the guide posts 42, wherein the outer edge contour of the guide posts 42 matches the inner edge contour of the guide sleeves 52, so that when the guide sleeves 52 are movably sleeved outside the guide posts 42, the position shaking between the two is avoided, thereby affecting the relative fixation of the position of the seat plate 5. Thus, through the four corners of the four guide posts 42, when the height of the seat plate 5 is adjusted by screwing the adjustment nut 53, the seat plate 5 is only displaced in the vertical direction. In addition, in this embodiment, the height of the plane where the top surface of the adjustment stud 44 is located is not greater than the height of the plane where the top surface of each guide post is located, so as to prevent the guide sleeve from being separated from the guide post when the adjustment nut 53 is screwed to the maximum height.

[0035] See also Figure 4, when the device is in use, first remove the old drive motor from the seat body, then hoist the new drive motor. After fixedly connecting the fixing flange at the end of the drive motor to the vertical plate and ensuring that the drive motor shaft is concentric with the drive through hole, adjust the displacement screw to adjust the front and rear positions of the seat plate. After ensuring that the seat plate can effectively support the drive motor, use a wrench to adjust the adjusting nut so that the seat plate fits and bears force against the bottom of the drive motor. Then disconnect the hoisting point of the drive motor, and all the loads of the drive motor are transferred to this drive connection device, and the connection device realizes an adaptable and stable support for the drive motor.
