Description

Technical Field

[0001] This utility model relates to the field of plate chain elevator technology, and more specifically to an anti-vibration guide device for a high-speed plate chain elevator. Background Technology

[0002] As a core piece of equipment for vertical material conveying in modern industry, plate chain elevators are widely used in mining, metallurgy, building materials, grain, chemical and other fields due to their advantages such as robust structure, large lifting height and strong adaptability. However, with the expansion of production scale and the increase in efficiency requirements, the violent shaking of the chain and load-bearing components becomes particularly prominent when the operating speed increases or the load increases significantly.

[0003] Jitter is essentially an unstable lateral vibration phenomenon in a high-speed chain system during the engagement, disengagement, steering, and sudden load changes of the drive sprocket. This vibration is caused by the coupling of factors such as polygonal effect, inertial impact, tension fluctuation, and external excitation. The severe lateral swaying first causes serious rigid impact and sliding friction between the chain and the guide rail, which accelerates the wear of the chain hinge, chain plate edge, and guide rail working surface, significantly shortens the life of key components, and increases maintenance costs and downtime risks.

[0004] Nowadays, guide devices are generally set up to guide and limit the chain, thereby reducing its vibration amplitude. However, when conveying different materials, the vibration amplitude of the plate chain elevator is different. The current guide devices cannot be freely detected and adjusted, so they cannot be adapted to different conveying conditions. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an anti-vibration guide device for a high-speed plate chain elevator to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a vibration-proof guiding device for a high-speed plate chain elevator, comprising a feeding hopper, a side baffle above the feeding hopper, an output shaft movably connected inside the side baffle, an output gear fixedly connected to the side of the output shaft, a plate chain meshing with the side of the output gear, a feeding plate fixedly connected to the side of the plate chain, a support plate fixedly connected to the side of the side baffle away from the plate chain, a detection mechanism fixedly connected to one side of the top of the support plate, and a guiding mechanism fixedly connected to the other side of the top of the support plate, the sides of the detection mechanism and the guiding mechanism contacting the side of the plate chain; the guiding mechanism includes a mounting box for fixed support, an electromagnet fixedly connected to the side of the mounting box away from the side baffle, a magnetic plate provided on the side of the electromagnet, the side of the magnetic plate away from the electromagnet contacting the side of the plate chain, and a clearance hole for the guide rod to move is opened inside the side baffle.

[0007] Furthermore, support plates are fixedly connected to the top and bottom of the side baffles on both sides away from the plate chain, and a detection mechanism and a guide mechanism are fixedly connected to the top of each support plate.

[0008] Furthermore, a fixing pad is fixedly connected to the bottom of the mounting box, and the bottom end of the fixing pad is fixedly connected to the top end of the support plate. When the electromagnet is energized, there is a magnetic repulsion between it and the magnetic plate.

[0009] Furthermore, each of the four corners of the electromagnet's side is fixedly connected with a fixing rod, and the inside of the magnetic plate is provided with a limiting hole that matches the fixing rod. The side of the fixing rod is provided with a spring, and the spring is located on the side of the magnetic plate away from the electromagnet.

[0010] Furthermore, the detection mechanism includes a fixed plate and a limiting plate for support. The bottom ends of the fixed plate and the limiting plate are fixedly connected to the top end of the support plate. A limiting rod is movably connected inside the limiting plate. A pressure sensor is fixedly connected to the side of the fixed plate near the limiting plate.

[0011] Furthermore, a connecting block is fixedly connected to the side of the limiting rod near the fixed plate, and an elastic head is fixedly connected to the side of the limiting rod away from the fixed plate. The elastic head can be compressed, and the side of the elastic head contacts the side of the plate chain.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model comprises an electromagnet, a magnetic plate, and a guide rod. When the electromagnet is energized, a magnetic repulsion force is generated between it and the magnetic plate. Under the action of the magnetic repulsion force, the magnetic plate moves away from the electromagnet. When the magnetic plate moves, it drives the guide rod to move. After the guide rod moves, it contacts the side of the plate chain, thereby guiding and limiting the tilted plate chain, reducing its vibration amplitude. Moreover, the force applied to the plate chain by the guide rod can be changed according to the current value of the electromagnet, and it can be freely adjusted in different environments.

[0014] 2. This utility model, by incorporating an elastic head, a connecting block, a limiting rod, and a pressure sensor, allows the elastic head to be compressed when the plate chain tilts. This compression causes the limiting rod and connecting block to move, and the moving connecting block then contacts the pressure sensor, thus compressing it. The pressure value from the pressure sensor indicates the degree of tilt of the plate chain, and the current value of the electromagnet in the guide mechanism is adjusted accordingly. Therefore, effective guiding and limiting can be achieved under various conditions. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figure 1 and Figure 2 This utility model provides an anti-vibration guiding device for a high-speed plate chain elevator, including a feeding hopper 1, a side baffle 2 above the feeding hopper 1, an output shaft 3 movably connected inside the side baffle 2, an output gear 4 fixedly connected to the side of the output shaft 3, a plate chain 5 meshing with the side of the output gear 4, a feeding plate 6 fixedly connected to the side of the plate chain 5, a support plate 7 fixedly connected to the side of the side baffle 2 away from the plate chain 5, a detection mechanism 8 fixedly connected to one side of the top of the support plate 7, and a guide mechanism 9 fixedly connected to the other side of the top of the support plate 7. The sides of the detection mechanism 8 and the guide mechanism 9 are in contact with the side of the plate chain 5. The top and bottom of the two sides of the side baffle 2 away from the plate chain 5 are both fixedly connected to the support plate 7, and the top of each support plate 7 is fixedly connected to both the detection mechanism 8 and the guide mechanism 9.

[0023] In this embodiment, the top and bottom ends of the side baffles 2 away from the plate chain 5 are fixedly connected to the support plates 7, and the top ends of the support plates 7 are fixedly connected to the detection mechanism 8 and the guide mechanism 9. Therefore, the detection mechanism 8 and the guide mechanism 9 can perform detection and guide limiting at different positions, thereby improving the stability of the plate chain 5 and the feeding plate 6 during transportation.

[0024] Reference Figure 3 and Figure 5 The guide mechanism 9 includes a mounting box 902 for fixed support. An electromagnet 903 is fixedly connected to the side of the mounting box 902 away from the side baffle 2. A magnetic plate 904 is provided on the side of the electromagnet 903. The side of the magnetic plate 904 away from the electromagnet 903 contacts the side of the plate chain 5. The side baffle 2 has a clearance hole for the guide rod 907 to move. A fixing pad 901 is fixedly connected to the bottom of the mounting box 902. The bottom of the fixing pad 901 is fixedly connected to the top of the support plate 7. When the electromagnet 903 is energized, there is a magnetic repulsion between it and the magnetic plate 904. Fixing rods 905 are fixedly connected to the four corners of the side of the electromagnet 903. The magnetic plate 904 has a limiting hole that matches the fixing rod 905. A spring 906 is provided on the side of the fixing rod 905. The spring 906 is located on the side of the magnetic plate 904 away from the electromagnet 903.

[0025] In this embodiment, after the electromagnet 903 is energized, a magnetic repulsion force is generated between it and the magnetic plate 904. This causes the magnetic plate 904 to move the guide rod 907 away from the electromagnet 903. After the guide rod 907 moves, it contacts the plate chain 5, thereby pushing the tilted plate chain 5 back to its original position and guiding and positioning the plate chain 5. This reduces the vibration amplitude of the plate chain 5 during transportation and maintains its stability during transportation. When the magnetic plate 904 moves, it compresses the spring 906. When guidance is not needed, the guide rod 907 moves away from the plate chain 5 and will not affect it.

[0026] Reference Figure 3 and Figure 4 The detection mechanism 8 includes a fixed plate 801 and a limiting plate 802 for support. The bottom ends of the fixed plate 801 and the limiting plate 802 are fixedly connected to the top end of the support plate 7. A limiting rod 804 is movably connected inside the limiting plate 802. A pressure sensor 803 is fixedly connected to the side of the fixed plate 801 near the limiting plate 802. A connecting block 805 is fixedly connected to the side of the limiting rod 804 near the fixed plate 801. An elastic head 806 is fixedly connected to the side of the limiting rod 804 away from the fixed plate 801. The elastic head 806 can be compressed, and the side of the elastic head 806 contacts the side of the plate chain 5.

[0027] In this embodiment, when the inclined plate chain 5 moves to both sides, it will come into contact with the elastic head 806, thereby squeezing the elastic head 806 to move. After the elastic head 806 is squeezed, it will drive the limiting rod 804 and the connecting block 805 to move towards the pressure sensor 803. At this time, the connecting block 805 comes into contact with the pressure sensor 803 and squeezes the pressure sensor 803. The pressure sensor 803 will display the pressure value. The greater the pressure value of the pressure sensor 803, the greater the inclination of the plate chain 5.

[0028] The working principle of this utility model is as follows: When lifting and conveying materials, the output shaft 3 drives the output gear 4 to rotate. When the output gear 4 rotates, it drives the plate chain 5 to rotate, which in turn drives the feeding plate 6 to rotate while conveying the materials. When conveying materials, if the plate chain 5 tilts and vibrates, the tilted plate chain 5 will contact the elastic head 806 when it moves to both sides, thereby squeezing the elastic head 806 to move. After the elastic head 806 is squeezed, it drives the limit rod 804 and the connecting block 805 to move towards the pressure sensor 803. At this time, the connecting block 805 contacts the pressure sensor 803 and squeezes the pressure sensor 803. The pressure sensor 803 will display the pressure value. The greater the pressure value of the pressure sensor 803, the greater the tilt of the plate chain 5.

[0029] The electromagnet 903 is energized according to the value of the pressure sensor 803. The larger the value, the larger the current of the electromagnet 903. After the current is applied to the electromagnet 903, a magnetic repulsion force is generated between it and the magnetic plate 904. This causes the magnetic plate 904 to move the guide rod 907 away from the electromagnet 903. After the guide rod 907 moves, it comes into contact with the plate chain 5, thereby pushing the tilted plate chain 5 back to its original position, guiding and positioning the plate chain 5, reducing the vibration amplitude of the plate chain 5 during transportation, and maintaining its stability during transportation.

[0030] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
