Description

Technical Field

[0001] This utility model relates to the field of hydraulic support technology, specifically a coal seam shielding hydraulic support structure. Background Technology

[0002] There are two main types of support equipment for full-height working faces in domestic underground coal mines: two-column shield hydraulic supports and four-column support shield hydraulic supports. The two types of hydraulic supports have their own advantages and disadvantages in adapting to underground geological conditions. When the roof of the working face is broken, two-column shield hydraulic supports are generally used, which can better control the roof. When the floor of the working face is broken, four-column support shield hydraulic supports are generally used. The smaller ground pressure can reduce the damage to the floor and the phenomenon of the support "getting stuck", ensuring that the support can be moved smoothly.

[0003] Since hydraulic supports operate in underground mine tunnels and their presence is intertwined with the coal mining process, they are often located in dusty areas. The lack of effective collection and treatment of this coal dust exposes the miners to its effects, negatively impacting their health. Utility Model Content

[0020] 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.

[0021] Please see Figure 1-4 This utility model discloses a coal seam shielding hydraulic support structure, including a base 1, a hydraulic support body 2 and a dust suppression structure 3 at the top of the base 1, and the dust suppression structure 3 is located below the hydraulic support body 2.

[0022] The dust suppression structure 3 includes a rotating mechanism 301, an adjusting mechanism 302 is fixedly connected to the movable end of the rotating mechanism 301, a dust suppression nozzle 303 is provided at the movable end of the adjusting mechanism 302, and a water storage mechanism 304 is placed at the top of the rotating mechanism 301, and the water storage mechanism 304 is connected to the rotating mechanism 301.

[0023] The rotating mechanism 301 includes a drive box 305 and an inspection cover 306. The drive box 305 has a built-in motor 307 fixedly installed inside and a transmission wheel 308 rotatably connected to it. The output shaft of the built-in motor 307 is connected to the transmission wheel 308 via a transmission belt.

[0024] The adjustment mechanism 302 includes a mounting frame, on the inner side of which a hydraulic cylinder 310 is fixedly mounted. The movable end of the hydraulic cylinder 310 is fixedly connected to a lifting rod 311. The top end of the lifting rod 311 extends to the outer side of the mounting frame and is fixedly mounted on a mounting platform 312. A water supply pipe 313 is provided at the top end of the mounting platform 312. An external motor 314 is fixedly mounted on the outer side of the mounting platform 312. The output shaft of the external motor 314 is fixedly connected to the side end of the water supply pipe 313. The water supply pipe 313 is connected to the water inlet end of the dust suppression nozzle 303.

[0025] By setting up the dust suppression structure 3, the rotating mechanism 301 can drive the dust suppression nozzle 303 to perform a fan-shaped motion. Combined with the adjusting mechanism 302, the height and tilt angle of the dust suppression nozzle 303 can be adjusted, giving it the ability to dynamically adjust according to actual needs and flexibly adjust the dust suppression range to adapt to different working environments. By spraying fine water mist, it effectively captures and settles dust particles in the air, significantly reducing dust floating in the mine. With the reduction of dust in the mine, not only is the working environment improved, but the safety of operators is also enhanced, providing strong protection for their health and safety.

[0026] Specifically, the inspection cover 306 has a rotating opening inside, and a follower disk 309 is provided on the inner side of the rotating opening. The bottom end of the follower disk 309 is fixedly connected to the transmission wheel 308, and the bottom end of the follower disk 309 is fixedly connected to the top end of the mounting bracket.

[0027] In this embodiment, the follower disk 309 enables a stable connection between the transmission wheel 308 and the mounting bracket. At the same time, the follower disk 309 can rotate together with the transmission wheel 308, thereby ensuring the normal operation of the rotating mechanism 301.

[0028] Specifically, the water storage mechanism 304 includes a water tank 315, a sealing cover 316 is movably attached to the top of the water tank 315, a water supply valve 317 is provided on the front side of the water tank 315, the other end of the water supply valve 317 is connected to the water supply pipe 313, and an observation window is provided on the surface of the water tank 315, with a scale strip on the observation window.

[0029] In this implementation scheme, the water level inside the water tank 315 can be intuitively understood through the observation window and scale bar, so as to make timely water replenishment operations, thereby ensuring the continuous water supply of the dust suppression nozzle 303 and improving the dust suppression efficiency.

[0030] Meanwhile, the sealed cover 316 effectively prevents dust and other impurities from entering the water tank 315, ensuring water cleanliness and avoiding problems such as clogging of the dust suppression nozzle 303.

[0031] When in use, when it is necessary to reduce dust in the surrounding environment, the water supply valve 317 is opened, and the water in the water tank 315 flows into the water supply pipe 313 through the water supply valve 317, and then is transported to the dust suppression nozzle 303 through the water supply pipe 313, causing the dust suppression nozzle 303 to start dust suppression treatment.

[0032] When it is necessary to adjust the tilt angle of the dust suppression nozzle 303, the external motor 314 is started, driving the water pipe 313 to rotate, thereby driving the dust suppression nozzle 303 to adjust the tilt angle.

[0033] When the height of the dust suppression nozzle 303 needs to be adjusted, the hydraulic cylinder 310 is activated, and the mounting platform 312 is moved up and down through the lifting rod 311, thereby driving the dust suppression nozzle 303 to adjust its height.

[0034] Meanwhile, depending on the dust suppression requirements, the operator can adjust the height of the dust suppression nozzle 303 by controlling the extension and retraction of the hydraulic cylinder 310, and change the rotation speed of the dust suppression nozzle 303 by adjusting the speed of the external motor 314, thereby adjusting the dust suppression range and intensity.

[0035] When it is necessary to adjust the spraying range of the dust suppression nozzle 303, the built-in motor 307 is started to drive the transmission wheel 308 to rotate through the transmission belt, and the follower plate 309 drives the entire adjustment mechanism 302 and the dust suppression nozzle 303 to perform a fan-shaped movement, further expanding the dust suppression coverage area.

[0036] In summary, this coal seam shield hydraulic support structure, through the installation of a dust suppression structure 3, utilizes a rotating mechanism 301 to drive the dust suppression nozzles 303 in a fan-shaped motion. Furthermore, the adjusting mechanism 302 allows for height and tilt adjustment of the dust suppression nozzles 303, enabling them to dynamically adjust according to actual needs and flexibly adapt the dust suppression range to different working environments. By spraying fine water mist, it effectively captures and settles dust particles in the air, significantly reducing dust floating within the mine. The reduction in dust levels not only improves the working environment but also enhances the safety of operators, providing strong protection for their health and safety.

[0037] It should be noted that the specific models and specifications of the dust suppression nozzle 303, built-in motor 307, hydraulic cylinder 310, external motor 314, and water supply valve 317 in the coal seam shield hydraulic support structure need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0038] Furthermore, the power supply and operating principle of the dust suppression nozzle 303, built-in motor 307, hydraulic cylinder 310, external motor 314, and water supply valve 317 in the coal seam shield hydraulic support structure are clear to those skilled in the art and will not be described in detail here.

[0039] Furthermore, the working principles and wiring methods of the dust suppression nozzles 303, built-in motors 307, hydraulic cylinders 310, external motors 314, and water supply valves 317 in the coal seam shielded hydraulic support structure are commonplace and belong to conventional methods or common knowledge, so they will not be elaborated here.

[0040] Furthermore, the dust suppression nozzles 303, built-in motors 307, hydraulic cylinders 310, external motors 314, and water supply valves 317 in the coal seam shield hydraulic support structure are purchased from the market. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manuals, without requiring any creative work from technical personnel in this field.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
