Abstract
Description
Technical Field
[0001] This invention belongs to the field of self-moving tail section technology, specifically, it relates to a stepping self-moving tail section for belt conveyors. Background Technology
[0002] The self-propelled tail section of a belt conveyor is a major transportation device in coal mine tunneling faces. It is installed between the head section of the transfer conveyor and the tail section of the belt conveyor. The head section of the transfer conveyor overlaps with the guide rail of the self-propelled tail section. Coal is unloaded from the head section onto the self-propelled tail section and then transferred to the belt conveyor for transport to the surface. During tunneling, the face scraper conveyor and the roadway transfer conveyor advance forward a distance under the thrust of the hydraulic supports. At the same time, the head section of the transfer conveyor also advances forward by the same distance along the guide rail of the self-propelled tail section until the end of the guide rail. At this point, the self-propelled tail section and the guide rail must move forward to ensure the continued advancement of the head section of the transfer conveyor and the continuous operation of coal mining and transportation.
[0003] When the existing self-propelled tail slides, the sides of the slide rails and the device will slide and rub against each other. In order to enable the device to move smoothly and reduce the wear of the slide rails, the sides of the slide rails need to be cleaned. The outer side of the slide rails can be cleaned manually, but the inner side of the slide rails cannot be cleaned manually due to the obstruction of the device. If it is not cleaned for a long time, stones may wear down the slide rails and reduce the service life of the device.
[0004] In view of this, the present invention is proposed. Summary of the Invention
[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:
[0006] A stepping self-moving tail section for a belt conveyor includes a slide rail and a mounting platform located on top of the slide rail. The slide rail has two symmetrically distributed sections. The mounting platform has moving mechanisms at both ends. Each moving mechanism includes a drive wheel. The top of the drive wheel is mounted on the bottom of the mounting platform, and the bottom of the drive wheel is rotatably connected to the top of the slide rail.
[0007] The mounting platform is equipped with support mechanisms at both ends, each support mechanism including a hydraulic cylinder, which is used to support the overall lifting of the device.
[0008] Multiple mounting platforms are provided, and a cleaning mechanism is provided at the bottom between two adjacent mounting platforms. The cleaning mechanism is used to clean the inside of the slide rail.
[0009] The cleaning mechanism includes four sleeves arranged symmetrically in pairs. Each sleeve has a connecting frame mounted on its top, and the top of the connecting frame is mounted on the bottom of the mounting frame. One end of each sleeve is fitted with a conduit, which is a rigid conduit, and the other end is fitted with an air nozzle. The two air nozzles on the same side spray in opposite directions. The pad moves and drives the connecting rod to move via the support rod, thereby moving the piston. The piston away from the direction of movement of the slide rail, through cooperation with the sleeve, allows gas to be ejected through the conduit and the air nozzle, thus cleaning the slide rail. At the same time, the piston and sleeve on the other side perform air extraction. When the slide rail is stationary, the pad is blocked by the sleeper and cannot move, thus keeping the piston stationary. The sleeve away from the direction of movement of the drive wheel, through cooperation with the piston, cleans the slide groove. At the same time, the sleeve and piston on the other side perform air extraction. The slide groove can be cleaned during the repeated movement of the device without the need for manual cleaning.
[0010] A piston is slidably connected inside the sleeve. A connecting rod is installed between two pistons on the same side. A support rod is installed at the bottom of the connecting rod, and a pad is installed at the bottom of the support rod. Multiple sleepers are installed between the two slide rails at equal intervals. The length of the pad is adapted to the distance between two adjacent sleepers. The bottom of the pad extends to the bottom of the sleeper. The idler roller is used to drive the conveyor belt, and the correction wheel is used to prevent the conveyor belt from running off-center.
[0011] In a preferred embodiment of the present invention, the slide rail has grooves on both sides at the bottom, and fixed plates are installed on both sides of the drive wheel. Rollers are installed on the bottom of the fixed plates near the slide rail. The top of the rollers is in rolling connection with the top of the inner wall of the groove. The diameter of the rollers is smaller than the cross-sectional height of the groove. When the hydraulic cylinder drives the drive wheel to rise, the slide rail rises through the rollers and the groove.
[0012] In a preferred embodiment of the present invention, multiple equally spaced mounting blocks are installed on both sides of the mounting platform, and a protrusion is installed on the top of the mounting block. A mounting frame is provided between two adjacent mounting platforms. The mounting frame is spliced together from multiple channel steels. Mounting holes are provided at both ends of the mounting frame. The shape and size of the mounting holes are adapted to the protrusions.
[0013] In a preferred embodiment of the present invention, fixing blocks are installed on both sides of the top of the mounting platform, and telescopic rods are installed at both ends of the fixing blocks. The outer ends of the two telescopic rods on the same side are equipped with the same baffle. The length of the baffle is adapted to the length of the mounting platform, and the width of the baffle is greater than the width of the protrusion. A spring is movably sleeved between the telescopic rod and the baffle and the fixing block. The two ends of the spring are installed on one side of the baffle and the fixing block. The spring is always in a compressed state. By sliding the baffle and overcoming the elastic force of the spring, the baffle is offset from the top of the mounting frame. The mounting frame can be removed through the mounting hole, which facilitates disassembly of the device and transportation.
[0014] In a preferred embodiment of the present invention, a roller is mounted on the top of the mounting platform located between the two fixed blocks, and two symmetrically distributed correction wheels are mounted on the outside of the mounting platform located between the two fixed blocks.
[0015] In a preferred embodiment of the present invention, a support leg is installed at the bottom of the hydraulic cylinder, and the hydraulic cylinder lifts the support leg to raise the entire device.
[0016] Compared with the prior art, the present invention has the following advantages:
[0017] When the device moves, the hydraulic cylinder first operates, lifting the device via the support legs. At this time, the drive wheel rotates, and through rolling friction with the slide rail, it moves the slide rail. The slide rail's movement also moves the sleepers, which in turn move the pads. The pads, in turn, move the connecting rod via the support rod, thus moving the piston. The piston, moving away from the slide rail's direction of movement, cooperates with the sleeve to eject gas through the conduit and nozzle, cleaning the slide rail. Simultaneously, the piston on the other side works with the sleeve to evacuate air. After moving a certain distance, the drive wheel stops rotating. At this time, the hydraulic cylinder retracts, causing the support legs to retract, and the support... With the support legs off the ground, the entire device is supported by a slide rail. At this point, the drive wheel rotates in the opposite direction, and through its interaction with the slide rail, it moves the mounting platform and its connecting components, thus moving the entire device. The moving mounting platform moves the mounting frame, which in turn moves the sleeve through the connecting frame. At this point, the pad is blocked by the sleeper and cannot move, thus keeping the piston stationary. The sleeve away from the direction of the drive wheel's movement cleans the slide groove through its interaction with the piston. Simultaneously, the sleeve on the other side works with the piston to evacuate air. The slide groove is cleaned during the repeated movement of the device, eliminating the need for manual cleaning.
[0018] This invention uses a sliding baffle to overcome the spring force, thereby misaligning the baffle with the top of the mounting bracket. The mounting bracket can be removed through the mounting hole, facilitating disassembly of the device and making transportation convenient.
[0019] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.
[0028] Example 1:
[0029] like Figures 1 to 5 As shown, a stepping self-moving tail section for a belt conveyor includes a slide rail 1 and a mounting platform 4 located on top of the slide rail 1. The slide rail 1 has two symmetrically distributed sections. The mounting platform 4 has a moving mechanism at both ends. The moving mechanism includes a drive wheel 3. The top of the drive wheel 3 is mounted on the bottom of the mounting platform 4, and the bottom of the drive wheel 3 is rotatably connected to the top of the slide rail 1.
[0030] The mounting platform 4 is equipped with support mechanisms at both ends. The support mechanisms include hydraulic cylinders 14 and are used to support the overall lifting of the device.
[0031] Multiple mounting platforms 4 are provided, and a cleaning mechanism is provided at the bottom between two adjacent mounting platforms 4. The cleaning mechanism is used to clean the inside of the slide rail 1.
[0032] like Figures 1 to 5As shown, in a specific embodiment, grooves 2 are provided at the bottom of both sides of the slide rail 1, and fixing plates 16 are installed on both sides of the drive wheel 3. Rollers 17 are installed at the bottom of the fixing plates 16 near the slide rail 1. The top of the rollers 17 is in rolling connection with the top of the inner wall of the groove 2, and the diameter of the rollers 17 is smaller than the cross-sectional height of the groove 2. In this configuration, when the hydraulic cylinder 14 drives the drive wheel 3 to rise, the slide rail 1 rises through the rollers 17 and the groove 2.
[0033] like Figures 1 to 5 As shown, further, multiple equally spaced mounting blocks 7 are installed on both sides of the mounting platform 4. A protrusion 8 is installed on the top of the mounting block 7. A mounting frame 5 is set between two adjacent mounting platforms 4. The mounting frame 5 is spliced from multiple channel steels. Mounting holes 6 are opened at both ends of the mounting frame 5. The shape and size of the mounting holes 6 are adapted to the protrusion 8. Fixing blocks 9 are installed on both sides of the top of the mounting platform 4. Telescopic rods 11 are installed at both ends of the fixing blocks 9. The same baffle 12 is installed at the outer end of the two telescopic rods 11 located on the same side. The length of the baffle 12 is adapted to the length of the mounting platform 4. The width of the baffle 12 is greater than the width of the protrusion 8. A spring 10 is movably sleeved between the baffle 12 and the fixing block 9 of the telescopic rod 11. The two ends of the spring 10 are installed on one side of the baffle 12 and the fixing block 9. The spring 10 is always in a compressed state. In this configuration, by sliding the baffle 12 and overcoming the elastic force of the spring 10, the baffle 12 is offset from the top of the mounting bracket 5, and the mounting bracket 5 can be removed through the mounting hole 6, which facilitates disassembly of the device and makes transportation convenient.
[0034] Example 2:
[0035] like Figures 1 to 5As shown, the cleaning mechanism further includes a sleeve 21, of which four sleeves 21 are arranged symmetrically in pairs. The top of each sleeve 21 is equipped with the same connecting frame 20, and the top of the connecting frame 20 is installed at the bottom of the mounting frame 5. One end of the sleeve 21 is equipped with a conduit 22, which is a rigid conduit, and the other end of the conduit 22 is equipped with an air nozzle 23. The spray directions of the two air nozzles 23 on the same side are opposite. A piston 25 is slidably connected inside the sleeve 21. The same connecting rod 24 is installed between the two pistons 25 on the same side. A support rod 26 is installed at the bottom of the connecting rod 24, and a pad 27 is installed at the bottom of the support rod 26. Multiple sleepers 13 are installed between the two slide rails 1 at equal intervals. The length of the pad 27 is adapted to the distance between two adjacent sleepers 13, and the bottom of the pad 27 extends to the bottom of the sleeper 13. In this setup, the pad 27 moves and drives the connecting rod 24 to move via the support rod 26, thereby moving the piston 25. The piston 25, moving away from the direction of movement of the slide rail 1, cooperates with the sleeve 21 to allow gas to be ejected through the conduit 22 and the air nozzle 23, thus cleaning the slide rail 1. At the same time, the piston 25 on the other side and the sleeve 21 perform air extraction. When the slide rail 1 is stationary, the pad 27 is blocked by the sleeper 13 and cannot move, thus keeping the piston 25 stationary. The sleeve 21, moving away from the direction of movement of the drive wheel 3, cleans the slide groove 2 through cooperation with the piston 25. At the same time, the sleeve 21 on the other side and the piston 25 perform air extraction. During the repeated movement of the device, the slide groove 2 can be cleaned without manual cleaning.
[0036] Example 3:
[0037] like Figures 1 to 5 As shown, in a specific embodiment, a roller 18 is mounted on the top of the mounting platform 4 located between the two fixed blocks 9, and two symmetrically distributed correction wheels 19 are mounted on the outer side of the mounting platform 4 between the two fixed blocks 9. In this configuration, the roller 18 is used to drive the conveyor belt, and the correction wheels 19 are used to prevent the conveyor belt from running off-track.
[0038] like Figures 1 to 5 As shown, a support leg 15 is further installed at the bottom of the hydraulic cylinder 14. In this configuration, the hydraulic cylinder 14 lifts the entire device by pushing up the support leg 15.
[0039] The implementation principle of the stepping self-moving tail section of a belt conveyor in this embodiment is as follows: During movement, the hydraulic cylinder 14 first operates and lifts the device through the support leg 15. At this time, the drive wheel 3 rotates, driving the slide rail 1 to move through rolling friction with the slide rail 1. The slide rail 1 moves and drives the sleeper 13 to move. The sleeper 13 moves and drives the pad 27 to move. The pad 27 moves and drives the connecting rod 24 to move through the support rod 26, thereby causing the piston 25 to move. The piston 25, which is away from the direction of movement of the slide rail 1, allows gas to be ejected through the conduit 22 and the air nozzle 23 through the cooperation of the sleeve 21, thus cleaning the slide rail 1. At the same time, the piston 25 on the other side and the sleeve 21 perform air extraction. After moving a certain distance, the drive wheel 3 stops rotating. At this time, the hydraulic cylinder 14 first operates and lifts the device through the support leg 15. When cylinder 14 retracts, it causes support leg 15 to retract and lift off the ground. The entire device is supported by slide rail 1. At this time, drive wheel 3 rotates in the opposite direction. Drive wheel 3 rotates and moves mounting platform 4 and its connecting components through cooperation with slide rail 1, thereby realizing the movement of the entire device. The movement of mounting platform 4 drives mounting frame 5 to move. Mounting frame 5 drives sleeve 21 to move through connecting frame 20. At this time, pad 27 is blocked by sleeper 13 and cannot move, thus keeping piston 25 stationary. Sleeve 21 away from the direction of movement of drive wheel 3 cleans slide groove 2 through cooperation with piston 25. At the same time, sleeve 21 on the other side pumps air from piston 25. During the repeated movement of the device, slide groove 2 can be cleaned without manual cleaning.
[0040] This device uses a sliding baffle 12 to overcome the elastic force of the spring 10, thereby offsetting the top of the baffle 12 from the mounting bracket 5. The mounting bracket 5 can be removed through the mounting hole 6, which facilitates disassembly of the device and makes it convenient for transportation.
