Description

Technical Field

[0001] This utility model relates to the field of safety braking technology in coal mine transportation equipment, specifically to an intelligent damping device. Background Technology

[0002] When the potential energy of a conveyor exceeds the sum of its resistance energies, the conveyor's braking performance becomes particularly critical. The main safety issues that need to be addressed include runaway failures during operation, as well as parking brake and power failure braking problems.

[0003] According to the patent titled "An Intelligent Adjustable Damping Device" (Patent Publication No.: CN105114526A, Patent Publication Date: 2015-12-02), this device employs an axisymmetric design, with the portion of the rotating shaft located in the working chamber designed as a fence structure. The speed variation of the fence structure alters the shear force experienced by the shear-thickening fluid, thereby affecting the fluid's viscosity and adjusting the device's damping force. Changing the traditional linear design to an axisymmetric rotating shaft design not only eliminates radial and axial jitter and vibration but also ensures rapid equipment startup, thus improving work efficiency. When vibration and jitter occur on the rotating shaft, a large damping force is generated to achieve vibration reduction; under stable operation, a smaller damping force is maintained, enabling high-speed movement of the mechanism. Therefore, it effectively solves the contradictory problem of the large damping force required for vibration reduction and the small resistance required for movement.

[0004] Based on the aforementioned existing technologies, current intelligent damping devices still have the following problems: "runaway" malfunctions during conveyor operation, as well as parking braking and power failure braking issues. Traditional solutions, such as four-quadrant frequency converter control, brake braking, increasing conveyor belt tension, and adding steel damping plates, suffer from reduced conveyor belt slippage between the conveyor belt and rollers due to decreased slack side tension, leading to reduced braking effectiveness and potential heat damage to the conveyor belt surface and roller coating. Furthermore, while increasing conveyor belt tension can improve braking performance to some extent, it also complicates the conveyor structure and increases the workload of tail movement. Therefore, this invention provides an intelligent damping device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an intelligent damping device that solves the following problems associated with existing intelligent damping devices: "runaway" malfunctions during conveyor operation, as well as parking braking and power failure braking issues. Traditional solutions such as four-quadrant frequency converter control, brake braking, increasing conveyor belt tension, and adding steel damping plates are not ideal in practical applications. For example, when using these traditional braking methods, the reduced slack side tension of the conveyor belt easily causes slippage between the conveyor belt and the rollers, reducing the braking effect and potentially generating heat that damages the conveyor belt surface rubber and roller coating. Furthermore, while increasing the conveyor belt tension can improve the braking effect to some extent, it also makes the conveyor structure more complex and increases the workload of tail movement.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an intelligent damping device, including an intermediate connecting member, wherein damping mechanisms are provided at both ends of the intermediate connecting member to improve the braking effect, and the damping mechanisms include:

[0007] The movable part, located on the side of the intermediate connector, includes a set of movable seats. A tripod is fixedly installed on the top of the movable seats by bolts, and a triangular connecting rod is fixedly installed on the inner side of the tripod by bolts. An inclined damping plate is fixedly installed on the inclined surface of the tripod by bolts. A transverse damping plate is fixedly installed on the top of the movable seats. The materials of the inclined damping plate and the transverse damping plate are flame-retardant ultra-high molecular weight polyethylene.

[0008] A support section is located below the movable section and is used to support the movable section.

[0009] Adjustment sections are located at both ends of the support section and are used to adapt the device to different installation positions;

[0010] A fixing part is provided at one end of the adjusting part and is used to fix the device.

[0011] The limiting part is provided at both ends of the support part and is used to limit the movement of the movable part.

[0012] Preferably, the support includes a support base movably mounted below the triangular connecting rod, with connecting seats fixedly mounted at both ends of the support base, and a set of through slots opened inside the connecting seats, and a cylinder fixedly mounted at the bottom of the connecting seats, with the output end of the cylinder passing through the connecting seats and fixedly connected to the bottom of the triangular connecting rod.

[0013] Preferably, the adjustment part includes a mounting box fixedly installed on the side of the connecting seat. A slider is slidably installed inside the mounting box, and a fixing plate is fixedly installed on one side of the slider. A threaded post is fixedly installed on the top of the slider. A groove is opened on the top of the groove, and the threaded post is located inside the groove to adapt to sliding. A threaded sleeve is rotatably installed on the external thread of the threaded post, and a remote handle is fixedly installed on the top of the threaded sleeve.

[0014] Preferably, the fixing part includes a fixing frame fixedly installed on the side of the fixing plate, a mounting plate is fixedly installed on the outside of the horizontal plate of the fixing frame, and the mounting plate is fixedly installed with the mounting frame by bolts, and one end of the horizontal plate of the fixing frame is inserted into the interior of the mounting frame and fixedly installed by bolts.

[0015] Preferably, the limiting part includes two limiting seats at the two outer corners of the bottom of the connecting seat, and a limiting post is fixedly installed on the top of the limiting seat, and the limiting seat is fixed to the connecting seat by a nut and the limiting post.

[0016] Preferably, the limiting post is located inside the through groove, and the limiting post penetrates the movable seat to limit the movement of the movable part.

[0017] This invention provides an intelligent damping device. Compared with the prior art, it has the following advantages:

[0018] (1) The intelligent damping device is operated by a cylinder to push the triangular linkage upward. The triangular linkage drives the movable seat and the triangular frame to move synchronously. At the same time, the movable seat and the triangular frame drive the inclined damping plate and the transverse damping plate to move synchronously and lift them to the appropriate position so that they are in close contact with the belt. This generates additional friction to slow down the belt speed. It also improves the problems caused by traditional braking methods, such as conveyor belt and roller slippage, increased structural complexity, and wear of damping plate materials. This ensures the stable operation and safety of the conveyor under various working conditions.

[0019] (2) The intelligent damping device is equipped with an adjustment part. When the user rotates the threaded sleeve remotely, the threaded sleeve does not contact the top of the mounting box. At this time, the fixed plate pulls the slider to slide inside the mounting box, thereby adjusting the position of the fixed part, so that the device can be adapted to different installation positions.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-10 This utility model provides a technical solution:

[0033] The intelligent damping device includes an intermediate connector 5. Damping mechanisms are provided at both ends of the intermediate connector 5 to improve the braking effect. The damping mechanisms include:

[0034] The movable part 1 is located on the side of the intermediate connector 5 and includes a set of movable seats 11. A tripod 12 is fixedly installed on the top of the movable seat 11 by bolts, and a triangular connecting rod 15 is fixedly installed on the inner side of the tripod 12 by bolts. An inclined damping plate 13 is fixedly installed on the inclined surface of the tripod 12 by bolts, and a transverse damping plate 14 is fixedly installed on the top of the movable seat 11. The inclined damping plate 13 and the transverse damping plate 14 are made of flame-retardant ultra-high molecular weight polyethylene.

[0035] Support part 2 is disposed below movable part 1 and is used to support movable part 1;

[0036] Adjustment parts 3 are provided at the left and right ends of the support part 2 and are used to adapt the device to different installation positions;

[0037] The fixing part 4 is provided at one end of the adjusting part 3 and is used to fix the device.

[0038] The limiting part 7 is provided at both ends of the support part 2 and is used to limit the movement of the movable part 1.

[0039] The cylinder 6 operates, pushing the triangular connecting rod 15 upward. The triangular connecting rod 15 drives the movable seat 11 and the triangular frame 12 to move synchronously. When the movable seat 11 moves upward, the limiting post 72 slides inside the movable seat 11 to limit it. At the same time, the movable seat 11 and the triangular frame 12 drive the inclined damping plate 13 and the transverse damping plate 14 to move synchronously and lift them to the appropriate position, so that they are in close contact with the belt. This generates additional friction to slow down the belt speed. It also improves the problems of conveyor belt slippage, increased structural complexity and wear of damping plate material caused by traditional braking methods, ensuring the stable operation and safety of the conveyor under various working conditions.

[0040] The intelligent damping device, applied in downhill conveyor belts, utilizes modified flame-retardant ultra-high molecular weight polyethylene (UHMWPE) material to manufacture the damping plates. This material's high coefficient of friction and excellent flame-retardant properties significantly improve the conveyor's braking effect and overall safety performance in emergency situations such as belt overspeed or brake failure. The device is ingeniously designed; in emergencies, a cylinder can quickly lift the damping plate to the belt position, thereby significantly increasing friction and effectively reducing belt speed, preventing potential accidents. Furthermore, the device has low maintenance requirements and is compatible with various conveyor sizes.

[0041] Using flame-retardant ultra-high molecular weight polyethylene (UHMWPE) as the damping plate material provides extremely high wear resistance, impact resistance, corrosion resistance, and good self-lubricating properties. This material also has unique low-temperature resistance and non-fouling properties, as well as a long service life, meeting the needs of conveyors in complex environments.

[0042] Ultra-high molecular weight polyethylene (UHMWPE) materials undergo special modification treatment to improve their coefficient of friction, enabling them to provide more effective damping when in contact with the conveyor belt.

[0043] The shape, size, and installation position of the damping plate were designed to be suitable for the downward conveyor, ensuring that it is evenly distributed in the downward section of the conveyor, effectively reducing the tension of the conveyor belt and improving the braking effect.

[0044] By improving the flame-retardant and antistatic properties of the damping plate to meet the requirements of MT113-95 standard, the heat generated by friction and adhesion phenomenon are reduced, which greatly reduces the risk of fire and the possibility of static electricity accumulation.

[0045] Since the braking effect of the damping plate does not require additional management, even when the conveyor stops due to power failure, the damping plate can still exert a damping effect on the conveyor belt, making the power failure braking of the conveyor more reliable and eliminating the need for a cumbersome and complicated power failure braking system.

[0046] Suitable for different specifications of down-carrying conveyors, with an applicable bandwidth range of 800-2000mm, damping plate thickness ≥25mm, and friction coefficient ≥0.3, it can be widely used in the raw coal down-carrying process in industries such as coal mines.

[0047] By using damping plates made of modified flame-retardant ultra-high molecular weight polyethylene material, the braking ability of the conveyor in emergency situations (such as belt overspeed or brake failure) is significantly enhanced, effectively reducing the risk of safety accidents.

[0048] The high coefficient of friction of the damping plate and the fast-response cylinder lifting mechanism can quickly increase the contact friction with the belt, thereby effectively slowing down the belt speed and improving the overall braking effect.

[0049] Because the selected materials have extremely high wear resistance, impact resistance and corrosion resistance, the intelligent damping device does not require frequent replacement and maintenance during long-term use, thus reducing operating costs.

[0050] The selected flame-retardant ultra-high molecular weight polyethylene material not only meets the safety requirements of industrial production, but also complies with environmental protection standards, reducing the negative impact on the environment.

[0051] In this embodiment, the support part 2 includes a support base 21 that is movably installed below the triangular connecting rod 15. Both the left and right ends of the support base 21 are fixedly installed with connecting seats 22. A set of through slots 23 are opened inside the connecting seat 22. A cylinder 6 is fixedly installed at the bottom of the connecting seat 22. The output end of the cylinder 6 passes through the connecting seat 22 and is fixedly connected to the bottom of the triangular connecting rod 15.

[0052] The cylinder 6 is model DSNU-20-50-PPV-A. It is electrically connected to an external power source and is operated by a human-controlled control panel. It supports the movable part 1 through the support base 21 and the connecting base 22, and moves the movable part 1 up and down through the cylinder 6 installed at the bottom of the connecting base 22.

[0053] In this embodiment, the adjustment unit 3 includes a mounting box 31 fixedly installed on the side of the connecting seat 22. A slider 32 is slidably installed inside the mounting box 31, and a fixing plate 33 is fixedly installed on one side of the slider 32. A threaded post 35 is fixedly installed on the top of the slider 32. A groove 34 is opened on the top of the groove 34, and the threaded post 35 is located inside the groove 34 to adapt to sliding. A threaded sleeve 36 is rotatably installed on the external thread of the threaded post 35, and a remote handle 37 is fixedly installed on the top of the threaded sleeve 36.

[0054] When the user rotates the threaded sleeve 36 by the remote handle 37, the threaded sleeve 36 does not contact the top of the mounting box 31. At this time, the slider 32 is pulled by the fixing plate 33 to slide inside the mounting box 31, thereby making the position of the fixing part 4 adjustable, so that the device can be adapted to different installation positions.

[0055] In this embodiment, the fixing part 4 includes a fixing frame 41 fixedly installed on the side of the fixing plate 33. The mounting plate 42 is fixedly installed on the outside of the horizontal plate of the fixing frame 41, and the mounting plate 42 is fixedly installed with the mounting frame 43 by bolts. One end of the horizontal plate of the fixing frame 41 is inserted into the interior of the mounting frame 43 and fixedly installed by bolts.

[0056] The device is fixedly installed in the designated position by mounting bracket 43 and bolts.

[0057] In this embodiment, the limiting part 7 includes two limiting seats 71 fixedly installed at the two outer corners of the bottom of the connecting seat 22, and a limiting post 72 is fixedly installed on the top of the limiting seat 71. The limiting seat 71 is fixed to the connecting seat 22 by nuts and the limiting post 72.

[0058] In this embodiment, the limiting post 72 is located inside the through groove 23, and the limiting post 72 passes through the movable seat 11 to limit the movement of the movable part 1.

[0059] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0060] During operation, the user first rotates the threaded sleeve 36 via the remote handle 37. At this time, the threaded sleeve 36 does not contact the top of the mounting box 31. Then, the fixed plate 33 pulls the slider 32 to slide inside the mounting box 31, adjusting the position of the fixed part 4 to a suitable position. The device is then installed via the mounting bracket 43. Then, during braking, the cylinder 6 operates, pushing the triangular connecting rod 15 upward. The triangular connecting rod 15 drives the movable seat 11 and the triangular frame 12 to move synchronously. At the same time, the movable seat 11 and the triangular frame 12 drive the inclined damping plate 13 and the transverse damping plate 14 to move synchronously and lift them to a suitable position, so that they are in close contact with the belt, generating additional friction to slow down the belt speed.
