Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal mining support technology, and in particular to a large-angle coal mining support. Background Technology
[0002] The steep-angle coal mining support is a hydraulic support specifically designed for steep-angle coal seam mining. This equipment can effectively control the subsidence and displacement of the roof, prevent roof collapse, provide a safe space for coal mining operations, reduce the risk of accidents, and protect the lives of coal miners and the safe operation of equipment.
[0003] In actual use, existing supports are often used in dark environments, which makes maintenance time-consuming and inefficient. Furthermore, the environment makes it difficult to quickly assess the working status of support components. Therefore, there is a need for a large-angle coal mining support that allows for proactive daily inspections and remote monitoring of the support components by taking photographs. Utility Model Content
[0004] The purpose of this utility model is to provide a large-angle coal mining support to solve the problems mentioned in the background art, where existing supports, due to the relatively dark working environment, not only take a long time and are inefficient to troubleshoot problems during actual use, but also cannot quickly determine the working status of support parts due to environmental influences.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a large-angle coal mining support, comprising:
[0007] Coal mining hydraulic supports;
[0008] The detection component includes a blind-spot-free camera, a movable frame, an inclined plate, and a movable column; the blind-spot-free camera is fixed on the upper surface of the coal mining hydraulic support, the movable frame is located outside the blind-spot-free camera, the inclined plate is fixed on the outer surface of one side of the movable frame, and the movable column is fixed on the outer surface of one end of the movable frame.
[0009] Furthermore, a fixed frame is fixed on the upper surface of the coal mining hydraulic support, a motor is fixed on the outer surface of the other side of the fixed frame, a ball screw is fixed at the output end of the motor, and the outer surface of the ball screw nut is fixed to the moving column.
[0010] Furthermore, a guide hole is provided through the interior of the other side of the fixed frame, and a connecting frame is fixed to the outer surface of the bottom end of the movable column.
[0011] Furthermore, a magnetic column is fixed inside the connecting frame, and two sets of magnetic columns are provided. A connecting frame is fixed to the outer surface of one end of the magnetic column.
[0012] Furthermore, the connecting frame is internally threaded with a threaded post, and a scraper is fixed on the outer surface of the threaded post, with the lower surface of the scraper in contact with the inner surface of the fixing frame.
[0013] Furthermore, it also includes a lighting assembly, which includes a lighting lamp, a support frame, and a mounting frame; the lighting lamp is fixed to the outer surface of the movable frame, the support frame is fixed to the outer surface of the other side of the coal mining hydraulic support, and the mounting frame is fixed to the upper surface of the support frame.
[0014] Furthermore, a mounting plate is snapped into the inside of the mounting frame, and a cleaning cloth is attached to the lower surface of the mounting plate.
[0015] Furthermore, a threaded rod is fixed to the outer surface of the mounting plate, the threaded rod passes through and is connected to the interior of the mounting frame, and a connecting pipe is threaded to the outer surface of the threaded rod.
[0016] Compared with existing technologies, the advantages of this utility model are:
[0017] I. This utility model, through its set detection components, enables the rotation of a ball screw driven by a motor when the hydraulic support for coal mining needs to be inspected. This, in turn, drives a movable column to move horizontally within a fixed frame. Once the movable frame is outside the blind-spot camera, the camera takes pictures of the internal components of the hydraulic support to detect whether their operation is normal. During the movement of the movable column, the scraper contacts the inner surface of the fixed frame, and dust is discharged through the guide hole, ensuring the continued normal use of the movable column. This solution allows for autonomous daily inspection of the support and remote observation of the component status by taking photos.
[0018] Second, based on the first beneficial effect, when the lighting components are used in conjunction with the lighting components, the movable frame is used to move the lighting lamp to the required position when it is necessary to inspect the parts, thereby making the image captured by the blind spot camera clearer. When the surface of the lighting lamp is covered with dust, the lighting lamp is moved to the bottom of the cleaning cloth, and the lighting lamp can be cleaned by rubbing. This solution not only makes the image captured by the blind spot camera clearer, but also maintains the brightness of the lighting lamp. Attached Figure Description

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0031] Please see Figures 1-4 As shown, this embodiment is a large-angle coal mining support, including:
[0032] 11. Coal mining hydraulic support;
[0033] The detection assembly includes a blind-spot camera 21, a movable frame 22, an inclined plate 23, and a movable column 27. The blind-spot camera 21 is fixed on the upper surface of the coal mining hydraulic support 11, the movable frame 22 is located outside the blind-spot camera 21, the inclined plate 23 is fixed on the outer surface of one side of the movable frame 22, and the movable column 27 is fixed on the outer surface of one end of the movable frame 22.
[0034] The coal mining hydraulic support 11 provides support and working space for steeply inclined coal seam mining, withstands pressure from the roof, and ensures the safe operation of coal mining. The blind spot camera 21 is used to take pictures of the internal parts of the coal mining hydraulic support 11 so as to remotely observe the condition of the support parts, detect whether the parts are operating normally, and provide a basis for maintenance and repair. The movable frame 22 is used to properly store the blind spot camera 21 in the required position. The inclined plate 23 prevents debris from falling directly onto the lens of the blind spot camera 21. The movable column 27 is used to change the position of the movable frame 22.
[0035] A fixed frame 24 is fixed on the upper surface of the coal mining hydraulic support 11. A motor 25 is fixed on the outer surface of the other side of the fixed frame 24. A ball screw 26 is fixed at the output end of the motor 25. The outer surface of the nut of the ball screw 26 is fixed to the moving column 27.
[0036] The fixed frame 24 provides space for the installation and fixing of components such as motor 25 and ball screw 26. Motor 25 serves as a power source, outputting power to drive ball screw 26 to rotate. Ball screw 26 converts the rotational motion of motor 25 into linear motion, precisely controlling the moving position and speed of moving column 27.
[0037] A guide hole 28 is provided through the interior of the other side of the fixed frame 24, and a connecting frame 29 is fixed to the outer surface of the bottom end of the movable column 27.
[0038] The guide hole 28 provides a discharge channel for the dust formed when the scraper 294 is in contact with the inner surface of the fixed frame 24, ensuring that the dust can be discharged smoothly. The connecting frame 29 is used to support and install the connecting bracket 292.
[0039] A magnetic post 291 is fixed inside the connecting frame 29. There are two sets of magnetic posts 291. A connecting bracket 292 is fixed on the outer surface of one end of the magnetic post 291.
[0040] The magnetic post 291 is used to confine the connecting frame 292 inside the connecting frame 29. The connecting frame 292 is used to receive and install the threaded post 293, thereby fixing the scraper 294 in the required position.
[0041] The connecting frame 292 has a threaded post 293 internally connected to it. A scraper 294 is fixed on the outer surface of the threaded post 293. The lower surface of the scraper 294 is in contact with the inner surface of the fixed frame 24.
[0042] The threaded post 293 is used to fix the scraper 294 in the desired position, and the scraper 294 is used to clean the dust inside the fixing frame 24.
[0043] Working principle: When the coal mining hydraulic support 11 needs to be inspected, the motor 25 drives the ball screw 26 to rotate, which in turn drives the moving column 27 to move horizontally inside the fixed frame 24. After the moving frame 22 is removed from the outside of the blind spot camera 21, the blind spot camera 21 takes pictures of the state of the parts inside the coal mining hydraulic support 11, thereby detecting whether the operation of the parts inside the coal mining hydraulic support 11 is normal. During the movement of the moving column 27, the scraper 294 is in contact with the inner surface of the fixed frame 24, and the dust is discharged through the guide hole 28, ensuring the normal use of the moving column 27 in the future.
[0044] When the scraper 294 needs to be replaced, move the connecting frame 29 to the guide hole 28, apply a pulling force to the connecting bracket 292 to pull the connecting bracket 292 out of the connecting frame 29, apply a rotating force to the scraper 294 to remove the threaded post 293 from the connecting bracket 292, rotate the threaded post 293 on the surface of the new scraper 294 into the connecting bracket 292, and then insert the connecting bracket 292 into the connecting frame 29 so that the two sets of magnet posts 291 are connected together.
[0045] This step involves autonomously conducting routine inspections of the support system and remotely monitoring the condition of its components by taking photos.
[0046] Please see Figures 1-4 As shown, this embodiment is based on the above embodiment and also includes a lighting component. The lighting component includes a lighting lamp 31, a support frame 32 and a mounting frame 33. The lighting lamp 31 is fixed on the outer surface of the movable frame 22, the support frame 32 is fixed on the outer surface of the other side of the coal mining hydraulic support 11, and the mounting frame 33 is fixed on the upper surface of the support frame 32.
[0047] When the lighting 31 is insufficient inside the steep-angle coal mining support, it provides additional lighting for the blind-spot-free camera 21, making the captured images clearer. The support frame 32 is used to fix the mounting frame 33 in the required position, and the mounting frame 33 is used to support and install the mounting plate 34.
[0048] The mounting frame 33 is fitted with a mounting plate 34, and a cleaning cloth 35 is attached to the lower surface of the mounting plate 34.
[0049] Mounting plate 34 is used to support and install cleaning cloth 35, which is used to wipe the surface of lighting lamp 31 that is contaminated with dust.
[0050] A threaded rod 36 is fixed to the outer surface of the mounting plate 34. The threaded rod 36 passes through and is connected to the inside of the mounting frame 33. A connecting pipe 37 is threadedly connected to the outer surface of the threaded rod 36.
[0051] The threaded rod 36 is used to confine the mounting plate 34 inside the mounting frame 33, while the connecting tube 37 is used to stably fix the mounting plate 34 in the desired position.
[0052] Working principle: When it is necessary to inspect the parts, the movable frame 22 is used to move the lighting lamp 31 to the required position, so that the image captured by the camera 21 with no blind spots is clearer. When the surface of the lighting lamp 31 is covered with dust, the lighting lamp 31 is moved to the bottom of the cleaning cloth 35 and the lighting lamp 31 can be cleaned by rubbing.
[0053] When the cleaning cloth 35 needs to be replaced, first remove the connecting tube 37 from the surface of the threaded rod 36, then remove the mounting plate 34 from the inside of the mounting frame 33, tear the cleaning cloth 35 off the bottom of the mounting plate 34, stick the new cleaning cloth 35 to the surface of the mounting plate 34, then insert the mounting plate 34 into the inside of the mounting frame 33, and use the connecting tube 37 and threaded rod 36 to fix the threaded rod 36 in the desired position.
[0054] This step not only makes the images captured by the all-around camera 21 clearer, but also maintains the illumination brightness of the lighting lamp 31.
