Description

Technical Field

[0001] This invention relates to the field of vertical shaft hoists, and more particularly to a device and method for real-time measurement of whether the disc brake of a vertical shaft hoist is working properly. Background Technology

[0002] Vertical shaft hoists are core equipment in vertical shaft mining, used for the vertical transportation of ore, coal, gangue, personnel, materials, and equipment. They serve as the "throat" connecting the surface and underground. A vertical shaft hoist is driven by an electric motor to rotate a drum, which in turn moves the steel wire rope wound around the drum, thus pulling the hoisting container up and down along the guideway. As a core piece of vertical transportation equipment, vertical shaft hoists are widely used in mining, construction, port logistics, municipal and environmental engineering, and other fields, offering significant advantages such as high-efficiency transportation, safety and reliability, strong adaptability, high space utilization, and potential for intelligent operation. In the mining sector, vertical shaft hoists are used to transport valuable minerals such as coal and ore, achieving efficient transport from underground to the surface; transport gangue and materials; and lift personnel and equipment, ensuring the continuity of mining operations. They are suitable for mines with large hoisting heights and high production capacities, with multi-rope friction hoists meeting the needs of large-tonnage transportation.

[0003] The disc brake of a vertical shaft hoist is a hydraulic actuator used in the braking system of a mine hoist. Currently, the braking system of a vertical shaft hoist is relatively complete. A hoist braking system consists of multiple sets of disc brakes. The entire disc brake system displays a set of hydraulic oil pressure data. However, the hydraulic oil pressure data of a set of total disc brake system cannot accurately reflect the actual oil supply pressure data of a single disc brake. If the oil supply line of a single disc brake is blocked, the single disc brake will not work properly, and there will be data distortion, making it difficult to detect the problematic single disc brake in time.

[0037] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0038] Figures 1 to 11 The diagram shown is a structural schematic of an embodiment of the device and method for real-time measurement of whether the disc brake of a vertical shaft hoist is working properly according to the present invention.

[0039] Example 1 like Figures 1 to 3 As shown, the device and method for real-time measurement of whether the disc brake of a vertical shaft hoist is working properly includes a support frame 1, on which multiple disc brake bodies 2 are symmetrically installed on both sides; Brake shoe disc assembly 3 and power module 4, each disc brake body 2 is provided with a brake shoe disc assembly 3 on one side, and a power module 4 is installed on the other side of the disc brake body 2. The output end of the power module 4 passes through the disc brake body 2 and is connected to the brake shoe disc assembly 3. The power module 4 controls the operation of the brake shoe disc assembly 3. Hydraulic supply and distribution pipeline 5, one end of which is connected to power module 4, and the other end of which is connected to hydraulic station; The monitoring mechanism includes a hydraulic oil monitoring component 6, which is connected to the hydraulic supply and distribution pipeline 5. The hydraulic oil monitoring component 6 is used to monitor the operating status of the disc brake.

[0040] Vertical shaft hoists are core equipment used for transporting materials and personnel in vertical shafts. They are driven by electric motors to rotate drums, which in turn drive steel wire ropes to lift containers such as skips or cages up and down along the hoistway, achieving efficient and safe vertical transportation. For safety reasons, a braking system needs to be installed when using a vertical shaft hoist to brake the hoist and ensure its safe operation.

[0041] Disc brakes are mainly composed of disc brakes, oil inlet pipes, distributors, supports, brake shoe wear protection devices, etc. Among them, the disc brake is the core braking component. It uses a hydraulic system to drive a piston to squeeze the brake block and clamp the brake disc that rotates with the drum to generate braking torque. The brakes are used in pairs symmetrically to ensure that no additional lateral load is generated on the brake disc and drum during the braking process.

[0042] When the hydraulic station outputs pressurized oil into the cylinder, the piston is subjected to oil pressure to overcome the preload of the disc spring and compress the disc spring, which drives the brake shoe to move backward, so that a gap is formed between the brake shoe and the brake disc, releasing the positive braking pressure, and the hoist starts to run. The hydraulic station adjusts the pressure according to the working conditions. When the oil pressure decreases, the disc spring assembly acts on the brake shoe through the push shaft and wear compensation stud, applying a positive spring force to make the brake shoe fit against the brake disc, generating a positive braking pressure and restricting the rotation of the brake disc.

[0043] In this technical solution, the hydraulic oil monitoring component 6 can monitor the oil supply pressure of a single disc brake in real time. By comparing the oil supply pressure of a single disc brake with the hydraulic oil pressure of the total disc brake system when it is working, when the oil supply pressure of a single disc brake is significantly lower than the hydraulic oil pressure of the total disc brake system when it is working, it indicates that the disc brake is not working properly and there may be a blockage or oil leakage in the oil supply line.

[0044] The hydraulic oil monitoring component 6 includes a connecting pipe 61, one end of which is connected to the hydraulic oil monitoring component 6, and the other end of which is detachably connected to a three-way pipe 62. One end of the three-way pipe 62 is detachably connected to an exhaust valve 63, and the other end of the three-way pipe 62 is detachably connected to a pressure gauge 64.

[0045] In this technical solution, the hydraulic oil monitoring component 6 is used to monitor the oil supply pressure of a single disc brake in real time.

[0046] When in use, remove the original bleed valve from the oil supply line of the single disc brake, then install a three-way pipe 62 through the connecting pipe 61, then install a bleed valve 63 at one joint of the three-way pipe 62, and install a pressure gauge 64 at the other joint of the three-way pipe 62. When the vertical shaft hoist is working, the disc brakes will also work. At this time, the pressure value in the oil supply line of each disc brake is measured by pressure gauge 64. The hydraulic oil pressure value of the oil supply line of each disc brake can be determined in real time. By comparing the oil supply pressure of each disc brake with the hydraulic oil pressure value of the total disc brake system, the working status of each disc brake can be reflected in real time. When the oil supply pressure of a single disc brake is significantly lower than the hydraulic oil pressure when the entire disc brake system is working, it indicates that the disc brake is not working properly and there may be a blockage or oil leakage in the oil supply line.

[0047] like Figure 11 As shown, the method includes the following steps: Step 1: Install hydraulic oil monitoring component 6. Remove the vent valve from the original disc brake oil supply line and install the three-way pipe 62 to the original vent valve. Then install the vent valve 63 at one end of the three-way pipe 62 and the pressure gauge 64 at the other end of the three-way pipe 62. Step 2: Measure the working status in real time. Determine the oil supply pressure of a single disc brake using pressure gauge 64. Compare the oil supply pressure of a single disc brake with the hydraulic oil pressure of the overall disc brake system when it is working. When the oil supply pressure of a single disc brake is significantly lower than the hydraulic oil pressure of the overall disc brake system when it is working, it indicates that the disc brake is not working properly.

[0048] Example 2 As one embodiment of this application, such as Figure 4 and Figure 5 As shown, the difference between it and other embodiments is that the monitoring mechanism further includes a width detection component 7, which includes an upper support plate 71 and a lower fixing plate 72. The upper support plate 71 is connected to the top of the disc brake body 2, and the lower fixing plate 72 is connected to the bottom of the disc brake body 2. A threaded adjusting shaft 73 is provided between the upper support plate 71 and the lower fixed plate 72. A moving block 74 is threadedly connected to the surface of the threaded adjusting shaft 73. A width detector 75 is installed on one side of the moving block 74.

[0049] In this technical solution, the thickness of the brake shoe disc assembly 3 is detected by the width detection component 7 to avoid excessive wear of the brake shoe disc assembly 3, which would affect the braking effect of the disc brake.

[0050] The bottom end of the threaded adjusting shaft 73 is rotatably connected to the top of the lower fixed plate 72, the upper support plate 71 is provided with a rotating hole, and the top end of the threaded adjusting shaft 73 is rotatably connected to the upper support plate 71 through the rotating hole. The top end of the threaded adjustment shaft 73 is connected to the output end of the drive source 76, and the drive source 76 is connected to the top of the upper support plate 71.

[0051] In this technical solution, the driving force for braking the threaded adjusting shaft 73 is provided by the driving source 76.

[0052] The disc brake body 2 has an anti-deviation groove on one side, and the moving block 74 is connected to an anti-deviation block 77 on one side, which slides in the anti-deviation groove.

[0053] In this technical solution, the movement trajectory of the moving block 74 is limited by the anti-deviation block 77 and the anti-deviation groove, making the movement of the moving block 74 and other structures more stable.

[0054] In use, the drive source 76 drives the threaded adjustment shaft 73 to rotate, thereby driving the moving block 74 to move, which in turn drives the width detector 75 to rotate. The width detector 75 is used to detect the width of the brake shoe disc assembly 3, that is, to detect the thickness of the brake shoe disc assembly 3, and to confirm the wear degree of the brake shoe disc assembly 3. Furthermore, when the moving block 74 moves, it drives the anti-deviation block 77 to move within the anti-deviation groove, thereby limiting the movement trajectory of the moving block 74.

[0055] Example 3 As one embodiment of this application, such as Figures 6 to 8 As shown, the difference between it and other embodiments is that the monitoring mechanism further includes a distance detection component 8, which includes a plurality of fixed reinforcing plates 81 and a number of follower plates 82 equal to the number of fixed reinforcing plates 81; Multiple fixed reinforcing plates 81 are connected to one side of the disc brake body 2, and multiple fixed reinforcing plates 81 are connected to one side of the brake shoe assembly 3; A sliding post 83 is connected to one side of the follower plate 82. The surface of the sliding post 83 is slidably connected to the fixed reinforcing plate 81. An indicator scale line 84 is engraved on the surface of the sliding post 83.

[0056] In this technical solution, the distance detection component 8 is used to monitor and confirm the distance between the brake shoe disc assembly 3 and the disc brake body 2, thereby determining the wear degree of the brake shoe disc assembly 3 and thus determining whether the disc brake can work normally.

[0057] The fixed reinforcing plate 81 has a preset hole, and the surface of the sliding column 83 is slidably connected to the fixed reinforcing plate 81 through the preset hole.

[0058] The end of the sliding column 83 away from the follower plate 82 is connected to an anti-detachment block 85, the diameter of which is larger than the inner diameter of the preset hole.

[0059] In this technical solution, the anti-detachment block 85 can prevent the sliding column 83 from sliding out of the preset hole.

[0060] In use, the power module 4 drives the brake shoe disc assembly 3 to brake the vertical shaft hoist. During this process, the movement of the brake shoe disc assembly 3 drives the follower plate 82 to move in the same direction, thereby driving the sliding column 83 to move in the same direction. At this time, the distance moved by the follower plate 82 can be confirmed by the indicator scale line 84. From the distance moved by the brake shoe disc assembly 3 each time, the wear condition of the brake shoe disc assembly 3 can be confirmed to confirm whether the disc brake can work normally.

[0061] Example 4 As one embodiment of this application, such as Figure 9 and Figure 10 As shown, the difference between this and other embodiments is that the monitoring mechanism further includes an auxiliary monitoring component 9, which includes a fixed mounting plate 91 and a movable mounting plate 92. The disc brake body 2 is connected to fixed mounting plates 91 on both the upper and lower sides, and the brake shoe disc assembly 3 is connected to movable mounting plates 92 on both the upper and lower sides. An infrared rangefinder transmitter group 93 is connected to the side of the fixed mounting plate 91 near the movable mounting plate 92, and an infrared rangefinder receiver group 94 is connected to the side of the movable mounting plate 92 near the fixed mounting plate 91. The center lines of the infrared rangefinder transmitter group 93 and the infrared rangefinder receiver group 94 are on the same horizontal straight line.

[0062] In this technical solution, the distance between the disc brake body 2 and the brake shoe assembly 3 can be detected using the auxiliary monitoring component 9 to determine whether the disc brake is working properly.

[0063] In use, the power module 4 drives the brake shoe disc assembly 3 to brake the vertical shaft hoist. During this process, the brake shoe disc assembly 3 drives the movable mounting plate 92 to move in the same direction, which in turn drives the infrared rangefinder receiver assembly 94 to move in the same direction. The distance moved by the brake shoe disc assembly 3 is confirmed by the infrared rangefinder transmitter assembly 93 and the infrared rangefinder receiver assembly 94. By comparing this distance with the distance moved when the disc brake is working normally, the wear condition of the brake shoe disc assembly 3 is confirmed to confirm whether the disc brake can work normally.

[0064] The drive source 76 is a motor set or other device that can output rotational kinetic energy.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.

When the oil supply pressure of a single disc brake is significantly lower than the hydraulic oil pressure of the total disc brake system when it is working, it indicates that the disc brake is not working properly.
