Description

Technical Field

[0001] This invention relates to the field of conveyor technology, and more particularly to a belt conveyor. Background Technology

[0002] Coal mine machinery, electrical equipment, and facilities are the foundation of coal mine production. Underground coal mining machinery and equipment mainly include hoisting equipment, ventilation equipment, compressed air equipment, pressure equipment, drainage equipment, mining equipment, support equipment, transportation equipment, power supply and electrical equipment, safety monitoring and gas drainage equipment. Transportation equipment mostly uses belt conveyors, which can transport large quantities of coal with strong conveying capacity. Patent document CN112849929B discloses a belt conveyor, including a conveying device, a drive device, a trigger slider mechanism, a scraping mechanism, an inclined support device, a sliding device, a cooperating device, and a hammering device. Its characteristic is that the drive device is connected to the trigger slider mechanism, the trigger slider mechanism is connected to the conveying device, and the scraping mechanism is connected to the conveying device. However, this device lacks effective support points. Due to the long conveying distance and the long conveyor belt, the pressure on the supports on both sides is high, making it unable to bear a large amount of coal, resulting in low transportation capacity. Therefore, we propose a belt conveyor. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as a lack of effective support leading to low transport capacity, and to propose a belt conveyor.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A belt conveyor includes a support frame and a vertical pipe. A drive wheel and a driven wheel are rotatably mounted on the support frame. A conveyor motor is connected to the drive wheel. The same conveyor belt is driven onto the drive wheel and the driven wheel. An adjusting motor and a support mechanism are installed inside the vertical pipe. The support mechanism includes a lifting screw, which is fixedly connected to the output shaft of the adjusting motor. A lifting plate is threaded onto the lifting screw. An L-shaped roller frame is fixedly mounted on the lifting plate. A support roller is rotatably mounted on the L-shaped roller frame. A slot is provided on the L-shaped roller frame, and an insert is rotatably mounted inside the support roller. Insert plates are inserted into both the slot and the insert tube. A secondary roller frame is fixedly mounted on the two insert plates. The vertical pipe is fixedly mounted with… Two slotted plates are fixedly installed, and extension mechanisms are provided within the two slotted plates. Each extension mechanism includes a first bevel gear fixedly connected to a lifting screw. Two second bevel gears mesh with the first bevel gear, and each of the two second bevel gears has a first pulley fixedly installed on it. Pushing screws are rotatably installed within each of the two slotted plates, and second pulleys are fixedly installed on each of the two pushing screws. Two belts are driven onto the two first pulleys and two second pulleys. Extension plates are threadedly connected to each of the two pushing screws, and multiple rollers are provided at the bottom of each of the two extension plates. Two mounting cavities are formed on the vertical pipe, and fixing and reinforcing mechanisms are provided within each mounting cavity. The fixing mechanism includes two racks, both of which are fixedly connected to the lifting plate. Two first gears are rotatably mounted inside the cavity, meshing with two racks. Each of the first gears has a vertical toothed plate meshing with it. A fixing rod is fixedly mounted on each of the two vertical toothed plates, and a nail cone is fixedly mounted on each of the two fixing rods. The reinforcement mechanism includes two second gears, rotatably connected to the inner walls of the two mounting cavities, meshing with two racks. A rope pulley is fixedly mounted on each of the two second gears, and a pull rope is fixedly connected to each of the two rope pulleys. Horizontal plates are slidably mounted inside each of the two mounting cavities. One end of each pull rope is fixedly connected to one of the two horizontal plates, and a compression spring is connected to one end of each of the two horizontal plates. Horizontal holes are formed on each of the two vertical toothed plates, and two support grooves are formed on the vertical tube. The two support grooves and the two horizontal holes are connected to... Two horizontal plates are inserted together. Multiple pulleys are rotatably installed in each of the two mounting cavities, and each pulley is movably connected to two pull ropes. Each mounting cavity has a maintenance door. Each mounting cavity has a grooved rail, which is slidably connected to two vertical toothed plates. A vertical rail is installed inside the vertical tube, which is slidably connected to a lifting plate. Slide rails are installed in each of the two mounting cavities, and these slide rails are slidably connected to two horizontal plates. Horizontal rails are installed inside each of the two grooved plates, and these horizontal rails are slidably connected to two extension plates. Two rotating shafts are rotatably installed inside the vertical tube, and these two rotating shafts are fixedly connected to two first pulleys. All the rotating parts described above are restricted by bearings, rotating shafts, or a combination of bearings and rotating shafts to ensure that all parts can rotate stably in a specific position.

[0006] The beneficial effects of the belt conveyor in this invention are as follows: the support mechanism can stably support the conveyor belt at different heights, reduce the stress on the support, and thus increase the load-bearing capacity and conveying capacity of the conveyor; the extension mechanism can increase the ground contact area, prevent the conveyor belt from pulling on the device, and increase stability; the fixing and reinforcement mechanisms can increase the adhesion of the device to the ground, prevent the device from shaking, and further improve stability, enabling the conveyor to stably transport coal.

An adjusting motor 7 and a support mechanism are installed inside the vertical pipe 2 to stably support the conveyor belt 6, reduce the pressure on the support frame, and improve the conveying capacity. The support mechanism includes a lifting screw 8, which is fixedly connected to the output shaft of the adjusting motor 7. A lifting plate 9 is threadedly connected to the lifting screw 8. An L-shaped roller frame 10 is fixedly mounted on the lifting plate 9, and a drive wheel 6 is rotatably mounted on the L-shaped roller frame 10. The device includes a support roller 11, an L-shaped roller frame 10 with a slot 12, a tube 13 rotatably mounted inside the support roller 11, and insert plates 14 inserted into both the slot 12 and the tube 13. A secondary roller frame 15 is fixedly mounted on the two insert plates 14. Two grooved plates 16 are fixedly mounted on the vertical tube 2, and an extension mechanism is provided in the two grooved plates 16. The extension mechanism can improve stability and prevent tipping due to force. Two mounting cavities 25 are provided on the vertical tube 2, and a fixing mechanism and a reinforcing mechanism are provided in the two mounting cavities 25. The cooperation of the fixing mechanism and the reinforcing mechanism can make the device stably fixed on the ground, prevent the device from sliding, and improve stability.

[0019] Reference Figures 1-3The extension mechanism includes a first bevel gear 17, which is fixedly connected to a lifting screw 8. Two second bevel gears 18 mesh with the first bevel gear 17. A first pulley 19 is fixedly installed on each of the two second bevel gears 18. A push screw 22 is rotatably installed in each of the two slot plates 16. A second pulley 20 is fixedly installed on each of the two push screws 22. Two belts 21 are driven on the two first pulleys 19 and the two second pulleys 20.

Nail cones 30 are fixedly installed on the two fixing rods 29.

[0021] Reference Figures 5-6 The reinforcement mechanism includes two second gears 31, which are rotatably connected to the inner walls of two mounting cavities 25. The two second gears 31 mesh with two racks 26. Each of the two second gears 31 is fixedly mounted with a rope wheel 32, and each of the two rope wheels 32 is fixedly connected with a pull rope 33. Each of the two mounting cavities 25 has a horizontal plate 34 slidably mounted inside. One end of each of the two pull ropes 33 is fixedly connected to the two horizontal plates 34. One end of each of the two horizontal plates 34 is connected to a compression spring 35. Each of the two vertical toothed plates 28 has a horizontal hole 37. The vertical tube 2 has two support grooves 36, and the two support grooves 36 and the two horizontal holes 37 are inserted into the two horizontal plates 34.

[0022] Reference Figures 1-6 Each of the two mounting cavities 25 has multiple pulleys 38 rotatably installed inside, and the multiple pulleys 38 are movably connected to two pull ropes 33 respectively. Each of the two mounting cavities 25 is provided with a maintenance door 39, which facilitates subsequent maintenance.

[0023] Reference Figure 2 A vertical rail is installed inside the vertical tube 2, and the vertical rail is slidably connected to the lifting plate 9. The vertical rail enables the lifting plate 9 to slide stably inside the vertical tube 2 without rotating.

[0024] Reference Figure 5 Both slots 16 are equipped with horizontal rails, which are slidably connected to the two extension plates 23. The horizontal rails enable the extension plates 23 to slide stably within the slots 16.

[0025] Reference Figure 3Two rotating shafts are rotatably installed inside the vertical tube 2. The two rotating shafts are fixedly connected to two first pulleys 19. The setting of the rotating shafts enables the first pulleys 19 to rotate stably in a fixed position.

[0026] Reference Figure 4 Both mounting cavities 25 are equipped with grooves, which are slidably connected to the two vertical toothed plates 28. The grooves enable the vertical toothed plates 28 to slide stably in a fixed position.

[0027] Reference Figure 6 Each of the two mounting cavities 25 is equipped with a slide rail, which is slidably connected to the two horizontal plates 34. The slide rails enable the horizontal plates 34 to slide stably in a fixed position.

[0028] In this embodiment, when a conveyor is needed to transport coal, the support 1 is positioned appropriately to taut the conveyor belt 6. The vertical pipe 2 is placed between the two legs of the support 1. The auxiliary roller frame 15 is pulled out so that the support roller 11 is positioned between the upper and lower belts of the conveyor belt 6. Then, the auxiliary roller frame 15 is inserted. At this time, the adjusting motor 7 is started, which drives the lifting screw 8 to rotate. The rotation of the lifting screw 8 drives the lifting plate 9 to rise, so that the L-shaped roller frame 10 drives the support roller 11 to rise and support the conveyor belt 6. The rotation of the lifting screw 8 drives the first bevel gear 17 to rotate. The first bevel gear 17 drives the two second bevel gears 18 to rotate. The two second bevel gears 18 drive the two first pulleys 19 to rotate. With the cooperation of the two belts 21, the two first pulleys 19 drive the two second pulleys 20 to rotate. The two second pulleys 20 drive the two push screws 22 to rotate. The two push screws 22 drive the two extension plates 23. Sliding to both sides increases the support area and stability. The lifting plate 9 rises, driving the two racks 26 to rise. At this time, the two racks 26 mesh with the first gear 27, thus driving the two first gears 27 to rotate, which in turn drives the two vertical tooth plates 28 to fall. This causes the two fixed rods 29 to drive the two nail cones 30 to fall and insert into the ground stabilizing device. The two racks 26 continue to rise, disengage from the two first gears 27, and mesh with the two second gears 31, driving the two second gears 31 to rotate, which in turn drives the two rope wheels 32 to rotate, releasing the two pull ropes 33. At this time, under the elastic force of the two compression springs 35, the two horizontal plates 34 are inserted into the horizontal holes 37 on the vertical tooth plates 28 and pass through the horizontal holes 37 to insert into the support grooves 36, fixing the vertical tooth plates 28, and thus fixing the support mechanism to support the conveyor belt 6, increasing the conveying capacity. Similarly, if the conveyor belt 6 is long, multiple support mechanisms can be selected for support, resulting in high stability.

[0029] Example 2

[0030] Reference Figure 7The difference between this embodiment and embodiment one is that: two fixed plates 40 are fixedly installed on each of the two extension plates 23, and fixed holes 41 are opened on each of the four fixed plates 40. When the conveyor is used to transport coal, if the support mechanism is adjusted, the extension plates 23 will not move. In this way, nails can be inserted into the fixed holes 41 and then inserted into the ground to further increase stability and enable the conveyor to operate stably.
