Description

Technical Field

[0001] This application relates to the field of dust control technology, and in particular provides a full-section spray vehicle for coal mine return airway. Background Technology

[0002] Dust suppression by spraying in the return airway of a coal mine is one of the core technologies for dust control in underground coal mines. It mainly uses tiny water mist particles generated by high-pressure spraying to collide, adsorb, and agglomerate with suspended dust in the return airway, ultimately causing the dust to settle, thereby reducing the dust concentration in the roadway, protecting the health of workers, and preventing dust explosion accidents.

[0003] In related technologies, a full-section spray dust suppression device is fixedly installed on the roof of the return airway to reduce dust concentration by forming a water mist barrier along the width of the roadway.

[0004] However, the fixed installation of the full-section spray dust suppression device makes it inconvenient to move. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description of this application is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

[0019] Dust suppression by spraying in the return airway of a coal mine is one of the core technologies for dust control in underground coal mines. It mainly uses tiny water mist particles generated by high-pressure spraying to collide, adsorb, and agglomerate with suspended dust in the return airway, ultimately causing the dust to settle, thereby reducing the dust concentration in the roadway, protecting the health of workers, and preventing dust explosion accidents.

[0020] In related technologies, a full-section spray dust suppression device is fixedly installed on the roof of the return airway to reduce dust concentration by forming a water mist barrier along the width of the roadway.

[0021] However, the fixed installation of the full-section spray dust suppression device makes it inconvenient to move.

[0022] Based on the above considerations, this application provides a full-section spray vehicle for coal mine return airways, which can solve the problem of inconvenient movement of existing full-section spray dust suppression devices.

[0023] The specific implementation of this application will be described in detail below with reference to specific embodiments.

[0024] Please see Figures 1-3 The embodiments of this application provide a full-section spray vehicle for coal mine return airway, including a lifting frame 20 fixed on the vehicle body 10, a mounting plate 30 fixedly connected to the lifting frame 20, a folding rod 31 hinged to the end of the mounting plate 30, a nozzle 33 provided on the folding rod 31, a folding cylinder 32 hinged to the mounting plate 30, and a connecting plate 311 hinged to both the folding rod 31 and the mounting plate 30 and simultaneously hinged to the folding cylinder 32.

[0025] The vehicle body 10 refers to the overall support structure of the full-section spray truck in the return airway of the coal mine. The vehicle body 10 adopts a wheeled structure and has movable wheels 11 installed at the bottom.

[0026] The folding rod 31 and other structures with nozzles 33 are arranged on the vehicle body 10. The movement of the vehicle body 10 can drive the overall structure to move, making it easy to adjust the position of the water mist barrier formed by the nozzles.

[0027] The lifting frame 20 refers to the lifting structure of the mounting plate 30, which can lift the mounting plate 30 to the target height.

[0028] The lifting frame 20 includes a lifting cylinder 23 arranged between two fixed frames.

[0029] The fixing frame includes a column 22 inserted into the guide cylinder 21. The lower end of the guide cylinder 21 is welded to the base plate 25, and the base plate 25 is bolted to the vehicle body 10. The column 22 is inserted into the guide cylinder 21 with a matching shape, and the column 22 can move up and down inside the guide cylinder 21. The top end of the column 22 is welded or bolted to the mounting plate 30.

[0030] Two parallel fixed frames are symmetrically arranged on both sides of the lifting cylinder 23. A crossbeam 24 is welded between the two guide cylinders 21. The lower end of the lifting cylinder 23 is hinged to the crossbeam 24, and the upper end of the lifting cylinder 23 is hinged to the lower end of the mounting plate 30.

[0031] When the lifting cylinder 23 extends, it pushes the mounting plate 30 upward; when the lifting cylinder 23 retracts, it drives the mounting plate 30 downward.

[0032] Mounting plate 30 is fixed to the top of lifting cylinder 23 and column 22. Folding rods 31 are hinged to both ends of mounting plate 30. The two folding rods 31 are respectively hinged to the front and rear sides of mounting plate 30. The folding rods 31 and mounting plate 30 have roughly the same longitudinal length. After being stored, the two folding rods 31 are located on the front and rear sides of mounting plate 30 respectively.

[0033] The fixed end of the folding cylinder 32 is connected to the middle position of the mounting plate 30 through the hinge shaft 321. The movable end of the folding cylinder 32 is provided with a connecting shaft 312. Both the hinge shaft 321 and the connecting shaft 312 are arranged parallel to the column 22. The folding cylinder 32 and the folding rod 31 are in one-to-one correspondence. Both the mounting plate 30 and the folding rod 31 are hinged with connecting plates 311. Both the mounting plate 30 and the folding rod 31 are hinged with the connecting shaft 312. The connecting plates 311 are symmetrically arranged at both ends of the connecting shaft 312.

[0034] The folding cylinder 32 drives the folding rod 31 to rotate via the connecting shaft 312, thereby realizing the folding and storage or extension and opening of the folding rod 31.

[0035] When the folding cylinder 32 retracts, it will drive the folding rod 31 to rotate until the two folding rods 31 rotate to the front and rear sides of the mounting plate 30 and are parallel to the mounting plate 30. At this time, the space occupied by the extension of the folding rod 31 can be greatly reduced. At the same time, the overall center of gravity of the spray module can be moved towards the vehicle body 10, improving the stability of movement.

[0036] It should be understood that a folding rod can be continued to be connected to the outer end of the folding rod 31.

[0037] The full-section spray vehicle for coal mine return airway provided in this application can reduce the encroachment on external space by folding the folding rod 31 into the mounting plate 30 through the folding cylinder 32. The vehicle body 10 drives the whole movement. Compared with the prior art, it can solve the problem of inconvenient movement of the full-section spray dust suppression device.

[0038] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
