Embodiment
[0036] see figure 1 and 3 , the present invention provides a tunnel dust suppression vehicle, including a body 10 , a dust suppression assembly 20 and a dust suppression assembly 30 .
[0037] Wherein, the vehicle body 10 is a vehicle equipment commonly used in the prior art, and its left side has a large enough accommodation space to facilitate the installation of the dust blocking assembly 20 and the dust suppression assembly 30; the umbrella frame mechanism 220 in the dust blocking assembly 20 is arranged in an umbrella shape , the use of the hydraulic structure can indirectly automatically expand and contract the umbrella frame mechanism 220, which is beneficial to block the dust after tunnel blasting in a wider area; The dust is sprayed, and the dust reduction effect is better.
[0038] see Figures 1 to 7, the dust blocking assembly 20 includes a hydraulic cylinder I 210 and an umbrella mechanism 220, the hydraulic cylinder I 210 is arranged on the vehicle body 10, sp...

The invention provides a tunnel dust blocking and falling vehicle, and belongs to the technical field of dust blocking and falling vehicles. The tunnel dust blocking and falling vehicle comprises a vehicle body, a dust blocking assembly and a dust falling assembly, wherein the dust blocking assembly comprises a hydraulic cylinder I and an umbrella rib mechanism, the hydraulic cylinder I is arranged on the vehicle body, the umbrella rib mechanism comprises a hydraulic cylinder II and a main sleeve rod, the hydraulic cylinder II is connected to the movable end of the hydraulic cylinder I, the main sleeve rod is connected to the outer wall of the fixed end of the hydraulic cylinder II, the two sides of the outer wall of the main sleeve rod are further connected with a fixed sleeve and a movable sleeve correspondingly, and hollow inclined supporting rods are hinged to the outer wall of the fixed sleeve at equal intervals. According to the tunnel dust blocking and falling vehicle, the umbrella rib mechanism can prevent dust after blasting from infinitely spreading in a hole, all high-pressure nozzles can be used for carrying out spraying and dust falling on the blocked and separated dust, spraying and rapid dust falling are carried out in a short time, a good operation space is provided for workers, storage is convenient, and the occupied space is reduced.
Description
technical field [0001] The invention relates to the field of dust-proof and dust-suppressing vehicles, in particular to tunnel dust-proof and dust-suppressing vehicles. Background technique [0002] After the tunnel blasting, a large amount of dust will be generated. In the traditional blasting process, the dust generated after the blasting lacks a mechanism to block its transmission, so it is easy to make the dust propagation space spread all the way to the outside of the tunnel entrance, causing large-scale pollution of the tunnel environment. At the same time The traditional spray dust suppression cannot cover all the areas, so it is difficult to quickly spray dust in a short period of time, and it cannot give workers a good working space. Contents of the invention [0003] In order to make up for the above deficiencies, the present invention provides a tunnel dust-resistance and dust-reduction vehicle, which aims to improve the problem of lack of dust-resistance and du...
