Description

Technical Field

[0001] The utility model belongs to the technical field of dust-proof water mist barriers, and in particular relates to a dust-proof water mist barrier system attached to a hydraulic trestle. Background Art

[0002] During tunnel construction, operations such as drilling, blasting, loading and unloading slag, and shotcrete spraying all generate large amounts of dust. The primary source of dust is from the tunnel face to the initial support of the invert arch, primarily at the front end of the hydraulic trestle. However, there are currently no dust control measures for this front end. This dust not only harms the respiratory systems of construction workers but also contaminates the oil and moving parts of mechanical equipment, accelerating wear and shortening its service life. Utility Model Content

[0003] The utility model aims to provide a dust-proof water mist barrier system attached to a hydraulic trestle, which has a significant dust-proof effect, protects the health of construction workers, and solves the problem that the dust damages the respiratory system of construction workers and pollutes the oil and moving parts of mechanical equipment due to the lack of dust-proof measures at the front end of the hydraulic trestle.

[0004] To this end, the technical solution adopted by the utility model is: a dust-proof water mist barrier system attached to the hydraulic trestle, including a water tank installed on the front end face of the hydraulic trestle, a nozzle main frame arranged in a mirror-symmetrical manner on the left and right side walls of the hydraulic trestle, a connecting spray pipe rotatably installed on the nozzle main frame, and atomizing nozzles installed one-to-one at the water outlet port of the connecting spray pipe. The water tank and the connecting spray pipe are connected through a pressurized water pump. The left and right side walls of the hydraulic trestle are provided with mounting grooves for mounting the nozzle main frame. The connecting spray pipe includes a connecting spray pipe 1 located on the upper and lower sides of the nozzle main frame and a connecting spray pipe 2 located on the side of the nozzle main frame facing the tunnel side wall. The water mist sprayed by all the atomizing nozzles can surround the hydraulic trestle in a circumferential direction, thereby forming a dust-proof water mist barrier.

[0005] As a preferred embodiment of the above scheme, the nozzle main frame includes a front bracket and a rear bracket, both of which are formed by horizontal and vertical rods and are correspondingly installed on the front and rear side walls of the mounting groove. The front bracket and the rear bracket are connected by longitudinal connecting rods spaced up and down. The structural connection is firmly installed and the design is reasonable.

[0006] Further preferably, the connecting spray pipe 1 is provided with four water outlet ports, and the connecting spray pipe 2 is provided with six water outlet ports. By flexibly adjusting the number and direction of the water blowing ports of the connecting spray pipe 1 and the connecting spray pipe 2, a water mist barrier surrounding the hydraulic trestle can be formed.

[0007] It is further preferred that the upper and lower sides of the front bracket and the side close to the tunnel side wall are provided with pipe mounting support plates, and the connecting spray pipe 1 and the connecting spray pipe 2 are provided with mounting rotating seats installed on the pipe mounting support plates, which are firmly installed and have a reasonable design structure.

[0008] More preferably, the mounting rotating seat is equipped with a driving motor for providing a rotational driving force, so that the rotation angle of the mounting rotating seat can be automatically controlled.

[0009] Beneficial effects of the utility model:

[0010] (1) Compared with the lack of dust prevention measures for the front end of the hydraulic trestle, this solution adopts the installation grooves set on the left and right side walls of the hydraulic trestle to install the nozzle main frame, and the water tank is installed on the front end of the hydraulic trestle, so that the entire dust-proof water mist barrier system can follow the hydraulic trestle forward without the need for additional mobile driving force. The nozzle bracket is concealedly installed to prevent collision. Two interconnected spray pipes are installed on the upper and lower sides of the nozzle main frame respectively, and the interconnected spray pipe is installed on the side of the nozzle main frame facing the tunnel side wall, so as to ensure that the upper and lower sides and the side facing the tunnel side wall are within the spraying range. The structure is linked together, the conception is novel, and the design is ingenious.

[0011] (2) By adjusting the number of water outlet ports and the spray angle of the connected spray pipe 1 and the connected spray pipe 2, a water mist barrier surrounding the hydraulic trestle is formed. The operation is flexible and ensures that the water mist barrier provides all-round dust protection for the front end of the hydraulic trestle. The dust prevention effect is significant, effectively avoiding dust hazards, protecting the health of construction workers, and extending the service life of mechanical equipment.

[0012] In summary, the utility model has the advantages of interlocking structure, novel conception, significant dust-proof effect, effective avoidance of dust hazards, protection of the health of construction workers, and extension of the service life of mechanical equipment.
