Description

Technical Field

[0001] The utility model relates to the technical field of coal mine production, in particular to a water sprinkling and dust reduction device for a monorail crane. Background Art

[0002] Traditionally, watering and dust reduction efforts in mine tunnels involve on-site workers using high-pressure hoses. This method requires the coordinated efforts of multiple workers, and the frequent dragging of high-pressure hoses weighing tens of kilograms is labor-intensive. In tunnels with varying widths or obstacles, conventional watering equipment, due to its fixed width, lacks flexibility, making it difficult to access narrow areas or bypass obstacles. This limitation prevents comprehensive dust reduction coverage, impacting effectiveness and sometimes even preventing the operation. Utility Model Content

[0003] In order to make up for the above-mentioned deficiencies, the utility model provides a water sprinkling and dust reduction device for a monorail crane, which can still work effectively when the width of the tunnel varies greatly or there are obstacles, so as to reduce manpower input, improve work efficiency and reduce labor intensity.

[0004] The utility model is realized through the following technical scheme: a water sprinkling and dust reduction device for a monorail crane, the technical key points of which are: it includes a water tank, a water inlet pipe is fixedly arranged on the upper part of the water tank, and a water outlet pipe is fixedly arranged on the front part of the water tank; a water pump and a solenoid valve are arranged on the water outlet pipe; the water outlet pipe is symmetrically arranged with branch pipes through a three-way joint, and the branch pipes are connected to the folding branch pipe through a rotating assembly; a fixed support rod is also fixedly arranged at the front part of the water tank, and a recess for limiting the folding branch pipe is provided on the fixed support rod; a magnet is fixedly arranged near the recess of the fixed support rod; a reinforcement rod is fixedly arranged between the water tank and the branch pipe; a limiting chain is fixedly arranged between the fixed support rod and the folding branch pipe; a plurality of water spray heads are fixedly arranged at the bottom of the branch pipe and the folding branch pipe; and a lifting ring is provided near the four corners of the upper part of the water tank.

[0005] Furthermore, the rotating assembly includes a first turning pipe connected to the branch pipe, a second turning pipe connected to the folding branch pipe, and a rotating pipe joint connected between the first turning pipe and the second turning pipe.

[0006] Furthermore, a button switch is fixedly provided at the front of the water tank, and the button switch is connected to the water pump and the solenoid valve through a relay.

[0007] Compared with the prior art, the present invention has the following advantages:

[0008] This new water sprinkler dust suppression device features a foldable branch pipe that fully covers the dust suppression area. When encountering narrow lanes or obstacles, the branch pipe can be folded to reduce the width of the device, allowing it to pass smoothly through narrow areas or bypass obstacles. This greatly improves the device's adaptability and flexibility, ensuring effective operation in a variety of complex lane conditions.

[0009] This utility model incorporates multiple safety features, including a magnet that attracts the folding branch to prevent it from slipping, and a limit chain that restricts the folding branch's rotation angle, ensuring stability and safety during use. Furthermore, a push-button switch controls the water pump and solenoid valve via a relay, enabling convenient control of the device and further enhancing operational safety.
