Description

Technical Field

[0002] A building is an entity that provides users or investors with a place to live, produce, work or carry out other activities at a planned and designed location. The purpose of building structural design is to ensure that the constructed structure is safe and applicable, can meet the requirements of various expected functions within the prescribed period of time, and is economical and reasonable.

[0003] Construction generates a significant amount of dust, necessitating the use of dust suppression equipment to reduce dust on construction sites by spraying water, thereby improving the dusty environment. However, current dust suppression equipment lacks flexibility, with limited adjustability in sprinkler height and tilt angle. This makes it difficult to achieve full coverage of dust removal at large-scale construction sites, leaving much room for improvement. Utility Model Content

[0008] In the dust suppression device, the sprayer can be supplied with water from an external water source, fixed on the horizontal axis through a support frame, initially cantilevered horizontally, and can be driven together with the horizontal axis through a horizontal steering mechanism. It can rotate within a range of 360° along the horizontal plane around the central axis of the power output shaft that is upright around the horizontal steering mechanism, and is used to adjust the spray direction of the sprayer. The horizontal axis is horizontal, and the central axis is not parallel to the central axis of the sprayer barrel in the initial posture. It can rotate around the central axis through the drive of the pitch steering mechanism, driving the sprayer to swing upward or downward, and is used to adjust the pitch angle of the sprayer.

[0009] The structural features of the present invention are:

[0011] The horizontal steering mechanism includes a steering motor, a steering transmission mechanism, and a steering sleeve. The driving force is provided by the steering motor and transmitted through the steering transmission mechanism. The output shaft of the steering transmission mechanism serves as the power output shaft of the horizontal steering mechanism, driving the steering sleeve fixed on the top end of the power output shaft and coaxially sleeved with the transverse shaft to rotate. The transverse shaft slidably penetrates the steering sleeve along the axial direction and can rotate around the central axis of the power output shaft together with the steering sleeve.

[0012] The steering transmission mechanism is a gear transmission mechanism, including a driving gear and a driven gear that are meshed with each other and have upright axles. The axle of the driving gear is coaxially connected to the output shaft of the steering motor. The axle of the driven gear serves as the power output shaft of the horizontal steering mechanism, and the steering sleeve is fixedly mounted on the top.

[0013] The pitch steering mechanism includes a pair of telescopic mechanisms, a limit plate, a pair of pitch transmission mechanisms, and a pair of connecting plates;

The transverse axis is rotatably mounted between the upper plate sections exposed above the limit plate. The pitch transmission mechanism includes a guide roller and a connecting arm. The guide roller is always built into the cavity of the limit plate and maintains rolling contact with the inner cavity wall of the limit plate. The guide roller is connected to the lower plate end of the connecting plate through the connecting arm. The pair of connecting plates and the pair of pitch transmission mechanisms can rotate 360 ​​degrees along the horizontal plane around the central axis of the power output shaft along the transverse axis. The pitch steering mechanism drives the limit plate to be lifted and lowered vertically through a pair of telescopic mechanisms. The pair of pitch transmission mechanisms rely on the rolling contact between a pair of guide rollers and the inner cavity wall of the limit plate to drive the pair of connecting plates to swing around the central axis of the transverse axis. The transverse axis rotates synchronously around the central axis with the swing of the pair of connecting plates.

[0015] The sprayer is an air-blast sprayer, in which an air-blast cylinder is mounted on a horizontal axis via a support frame.

[0017] The supporting frame is a cart with universal casters with brakes at the four corners of the bottom and a push-pull handrail at one side.

[0018] Compared with the existing technology, the beneficial effects of this utility model are embodied in:

[0019] The utility model utilizes a sprayer to sprinkle water on the construction site to achieve the purpose of dust reduction. The height position of the sprayer can be adjusted by a lifting device to meet the dust reduction operation needs at higher places. The pitch angle of the sprayer can be adjusted by a pitch steering mechanism. The spray direction of the sprayer in the horizontal direction can be adjusted by a horizontal steering mechanism, so that the dust reduction range of the sprayer is further increased. It can be applicable to air dust reduction operations at different positions, so that angle areas that were originally difficult to reduce dust can be more easily obtained by sprinkling water for dust reduction. The equipment has a wider dust reduction range and a better dust reduction effect, has low operation difficulty, is convenient to implement, and is suitable for popularization and application.
