Description

Technical Field

[0001] The utility model belongs to the technical field of dust suppression equipment, and in particular relates to dust suppression equipment for deep foundation pit excavation construction. Background Art

[0002] A deep foundation pit refers to excavating at least 5 meters of earth below the ground, and then carrying out operations, such as building a basement. Generally, projects below the ground usually require excavating a deep foundation pit first. For example, subway construction in urban transportation requires excavating a deep foundation pit. Therefore, dust suppression equipment is required during the excavation of the deep foundation pit of the subway.

[0003] The existing dust suppression equipment either uses dust-proof nets for laying or uses water spraying for dust suppression. Laying dust-proof nets is time-consuming and labor-intensive, which greatly increases the cost of dust suppression. When using water spraying for dust suppression, it is difficult to rotate the spray head during the dust suppression process, which can easily lead to areas that are not covered by the spray during dust suppression, thereby affecting the dust suppression effect. In addition, due to the different heights of deep foundation pits, the angle of the spray head needs to be adjusted during dust suppression, otherwise it is difficult to achieve the dust suppression effect. The existing spray head position angle is fixed, which greatly affects the applicability of the machine. Therefore, a dust suppression equipment for deep foundation pit excavation construction is needed to solve the above problems. Utility Model Content

[0012] The utility model is provided with a moving assembly to drive the spray assembly to rotate, so that the range of the spray can be increased, and the areas that are not covered by the spray during operation are prevented, thereby affecting the dust suppression effect. The driving gear is driven by the motor to rotate 60 degrees back and forth, which can drive the driven gear to rotate back and forth, and thus can drive the hydraulic telescopic rod on the turntable to rotate. The hydraulic telescopic rod is connected to the spray assembly, and the connecting pipe of the spray assembly can be made to swing back and forth inside the limit groove through the support rod and the arc slider, so that the dust suppression work can be better performed on deep foundation pits. The spray assembly can be limited by the limit groove to prevent the bellows from breaking due to excessive rotation. The spray assembly can be pushed to change its angle by the hydraulic telescopic rod, so that the machine can perform dust suppression work on deep foundation pits of different heights, greatly improving the applicability of the machine.

[0013] The utility model can support the spray assembly by providing a support rod and limit the spray assembly by using a rotating block to prevent it from deviating and falling during rotation and causing certain damage. The dust cover can prevent dust from entering the spray head through the dust cover during the dust suppression process, causing it to be blocked and affecting its use. The spray range of the spray head can be improved by setting the dust cover to an inverted bucket shape. BRIEF DESCRIPTION OF THE DRAWINGS
