Description

Technical Field

[0001] The invention relates to the technical field of dust suppression equipment, in particular to a mobile automatic dust suppression equipment. Background Art

[0002] A tunnel is an engineering structure buried in the ground. It is a form of human utilization of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mining tunnels, and military tunnels.

[0003] At present, when excavating existing tunnels or tunnels, explosives are usually used for blasting first, and then vehicles and manual labor are used to discharge the internal gravel and support the inside of the cavity to prevent soil blocks from falling. However, since the internal cavity is relatively closed when it is not opened, the dust and smoke generated by the blasting inside takes a long time to dissipate. Personnel working inside will suffer physical injuries due to inhaling a large amount of dust. Common dust removal is conducive to using a vacuum fan to suck away the dust in the tunnel or spraying water to reduce dust, but this requires a long ventilation duct connected to the tunnel to absorb and discharge the dust in the tunnel. The long ventilation duct has a greater impact on personnel construction, and the method of spraying water to reduce dust requires special personnel to operate water guns and other equipment to spray the inner wall of the cavity. Due to the height problem of personnel, the water outlet cannot be directly close to the inner wall of the cavity, and when the water pressure of the water gun is too high, it will also cause impact on the inner wall of the cavity. For this reason, we propose a mobile automatic dust reduction device. Summary of the invention

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example 1

[0027] See also Figure 1-Figure 4, a mobile automatic dust reduction device shown in the figure includes an angle iron track 1 and two arched plates 2 laid in the tunnel, an isolation cloth 3 is fixed between the two arched plates 2, and the bottoms of the two arched plates 2 are both equipped with running wheels connected to the angle iron track 1, and also includes two groups of water spray pipes 4 and driving rods 8, each group of water spray pipes 4 is provided with two, each group of water spray pipes 4 is installed on the inner wall and the outer wall of the arched plate 2, and a plurality of atomizing nozzles 5 are equidistantly installed on the outer side of the water spray pipe 4, and the outer end of the water spray pipe 4 is connected to the tunnel construction water supply through a water pipe Pipeline connection, openings 6 are opened on the two arched plates 2, and arched tooth plates 7 are fixed on the inner side walls of the openings 6, four driving rods 8 are provided, and are respectively installed in the two ends of the openings 6 in the two arched plates 2, and driving gears 9 meshing with the arched tooth plates 7 are fixed at both ends of the driving rod 8, a moving opening 10 is opened on the outer side of the arched plate 2, and a driving member 11 fixed to the outer end of the driving rod 8 is installed in the moving opening 10, and an adsorption mechanism 12 for adsorbing dust in the tunnel is installed on the outer side of the driving rod 8;

[0028] It should be noted that: the water source in the water spray pipe 4 is connected to the construction water pipe in the tunnel to realize the supply of water, and then the water mist is directly sprayed onto the inner wall of the tunnel through the atomizing nozzle 5 to achieve dust reduction at the source. Among them, the adsorption mechanism 12 set in the arch plate 2 can adsorb the residual turbid gas, achieve two-way dust reduction, and improve the dust reduction effect.

[0029] It is worth noting that: personnel can push the arch plate 2 to drive it to move in the tunnel, which is convenient for dust reduction at any position inside. At the same time, the atomizing nozzle 5 arranged on the inner wall of the arch plate 2 can form a water curtain, so that dust can be reduced in a large range.

[0030] It should also be noted that the distance between the two arched plates 2 is about 1 meter, which is convenient for personnel to push the arched plates 2 under the isolation cloth 3 to move and perform other operations.

[0031] Among them, see Figure 3 , Figure 7 and Figure 8 The adsorption mechanism 12 shown in the figure includes a side plate 13 rotatably mounted on both ends of the driving rod 8 and a large gear 14 fixed to both ends of the driving rod 8, and two transmission rods 15 are rotatably mounted between the two side plates 13, and the outer sides of the two transmission rods 15 are rotatably sleeved with a negative pressure cylinder 16, and the two negative pressure cylinders 16 are fixed to the side plates 13 through a fixing frame, and the outer ends of the two transmission rods 15 are fixed with a small gear 17 meshing with the large gear 14, and an adsorption component 18 is installed in the negative pressure cylinder 16, and support plates 19 are fixed to the bottom of both sides of the arch plate 2, and a dust handling component 20 is installed on the support plate 19;

[0032] It should be noted that: the driving rod 8 is driven by the driving member 11 to move along the arched tooth plate 7, so that the driving gear 9 rotates, and the driving rod 8 follows the rotation, and then the large gear 14 drives the two small gears 17 to rotate synchronously, thereby driving the adsorption component 18 to facilitate the adsorption of dust, and the adsorbed dust is processed by the dust processing component 20.

[0033] It is worth noting that: in order to facilitate personnel to push the arch plate 2, a pushing plate 45 is installed on the outer side of the support plate 19, which makes it more convenient for personnel to apply force.

[0034] Also, see Figure 7 The adsorption assembly 18 shown in the figure includes two air inlet pipes 21 fixedly connected to the outside of the two negative pressure cylinders 16, two air outlet pipes 22 are installed on the other side of the two negative pressure cylinders 16, and the two air outlet pipes 22 are installed with a one-way valve for exhausting air outward, and the two air inlet pipes 21 are installed with a one-way valve for inhaling air inward, and the outer sides of the two transmission rods 15 are engraved with reciprocating thread grooves, and the outer sides of the two transmission rods 15 are sleeved with piston plates 23, and the inner wall of the negative pressure cylinder 16 is provided with a limit strip 24 that is slidably docked with the piston plate 23;

[0035] It should be noted that: by rotating the driving rod 8 and cooperating with the transmission of the large gear 14 and the small gear 17, the rotation of the two transmission rods 15 is realized, and the reciprocating movement of the piston plate 23 is adjusted, so that the two air inlet pipes 21 can take turns to inhale air with the movement of the piston plate 23 and the action of the one-way valve, and the adsorbed turbid gas is sucked into the negative pressure cylinder 16. Through the reciprocating movement of the piston plate 23, the turbid gas is discharged through the two air outlet pipes 22 respectively, thereby achieving the adsorption of the turbid gas remaining on the inner wall of the tunnel, so that the dust removal effect is better.

[0036] It is worth noting that the installation of the one-way valves on the air inlet pipe 21 and the air outlet pipe 22 enables the air inlet pipe 21 to inhale gas under negative pressure conditions, while the air outlet pipe 22 discharges gas as the piston plate 23 moves.

[0037] Also, see Figure 3 and Figure 8 The driving member 11 shown in the figure includes a motor table 25 slidably plugged into the moving port 10, a driving motor 26 is installed on the outer side of the motor table 25, and an arc plate that is in sliding contact with the inner wall of the arch plate 2 is fixed to the tail end of the motor table 25, and the output end of the driving motor 26 is fixed to the outer end of the driving rod 8 through a coupling;

[0038] It should be noted that: by rotating the driving motor 26, the driving rod 8 connected thereto is driven to rotate, thereby realizing the driving of the driving rod 8. At the same time, the designed motor platform 25 moves in the moving opening 10, and cooperates with the arc plate and the inner wall of the arch plate 2 to slide against each other, so that when the driving rod 8 rotates and drives the driving gear 9 to rotate and move along the arched tooth plate 7, the driving motor 26 can also move accordingly in the moving opening 10 on the arch plate 2 under the action of the motor platform 25, thereby realizing the position adjustment of the negative pressure cylinder 16 and realizing the adsorption of various parts of the inner wall of the tunnel.

[0039] It is worth noting that in order to ensure that the side panels 13 can remain stable and not rotate or shake when the negative pressure cylinder 16 moves, a stabilizing rod 27 is fixed on the inner side of the side panels 13, and a movable groove 28 is opened on the inner side of the arch plate 2, and the stabilizing rod 27 is slidably inserted into the movable groove 28.

[0040] The principle of efficient dust reduction on the inner wall of the tunnel: first, personnel install two arched plates 2 on the angle iron track 1, and then personnel push the arched plates 2 to move on the angle iron track 1, and then connect with the water pipe in the tunnel to make the water pipe 4 full of water, and spray the water through the atomizing nozzle 5 to atomize and reduce dust on the inner wall of the tunnel. At the same time, through the rotation of the driving motor 26, the driving rod 8 is driven to rotate, so that the two driving gears 9 rotate and move on the arched tooth plate 7, and then through the mutual meshing of the large gear 14 and the small gear 17, the two transmission rods 15 can rotate, driving the movement of the piston plate 23, so that the air pressure at both ends of the two negative pressure cylinders 16 is adjusted, thereby controlling the air inlet pipe 21 and the air outlet pipe 22 at both ends to suck and exhaust air in turn, and adsorb the turbid gas remaining in the tunnel, greatly improving the dust reduction effect.

[0041] It should also be noted that in this solution, personnel only need to push the arch plate 2 to drive it to move in the tunnel, so that when personnel operate in the tunnel, the operating area can be dust-reduced to reduce dust in the personnel operating area. Changes in the personnel's working area can directly push the arch plate 2 to move, which is simple and convenient.

[0042] In this solution, an acoustic and optical sensor, a control main board and an electrically controlled valve can also be installed inside the arch plate 2, so that when an explosion occurs inside, the acoustic and optical sensor can detect the explosion, and the control main board can drive the electrically controlled valve to open the water valve, thereby achieving an automatic dust reduction effect.

[0043] Example 2

[0044] See also Figure 4-Figure 6, this embodiment further explains Example 1, the dust treatment assembly 20 shown in the figure includes a treatment box 29 fixed on the support plate 19, a support frame 30 is installed on the treatment box 29, and an L-shaped plate 31 is provided at one end of the support frame 30, rail openings 32 are opened on both sides of the support frame 30, and adjustment rods 33 plugged into the rail openings 32 are fixed on both sides of the L-shaped plate 31, adjustment members 34 for moving the position of the L-shaped plate 31 are installed on both sides of the treatment box 29, and a hose connected to the bottom of the treatment box 29 is installed at the tail end of the outlet pipe 22, and a storage rack 35 is installed on the support plate 19;

[0045] It should be noted that: by filling the treatment box 29 with water and then connecting the tail end of the outlet pipe 22 to the bottom of the treatment box 29 through a hose, the turbid gas can come into contact with the water in the treatment box 29 before being discharged, and absorb part of the dust through the water, and then pass through the sponge board on the support frame 30 to absorb the dust in the gas. Finally, after the sponge board absorbs more dust, a new sponge board is automatically replaced by the adjustment part 34.

[0046] Among them, see Figure 5 and Figure 6 The adjusting member 34 shown in the figure includes a rotating rod 36 rotatably mounted on one side of the processing box 29, and adjusting arms 37 are fixed to both ends of the rotating rod 36, and an adjusting port 38 for inserting the adjusting rod 33 is opened on the outer side of the adjusting arm 37, and an arc rod 39 is fixed to the bottom of the adjusting arm 37, and a stop plate 40 inserted with the arc rod 39 is fixed to the outer side of the processing box 29, and an arc extrusion spring 41 for pushing the tail end of the arc rod 39 outward is sleeved on the outer side of the arc rod 39, and the center of the arc rod 39 is consistent with the center of the rotating rod 36, and a support plate 42 is fixed to the bottom of the two adjusting arms 37, and a pressing rod 43 for pressing the support plate 42 is fixed to the outer side of the two side plates 13;

[0047] It should be noted that when the negative pressure cylinder 16 moves to the bottom along the inner wall of the arch plate 2, it will drive the pressing rod 43 to move downward and abut against the support plate 42, so that the two adjusting arms 37 rotate along the rotating rod 36, thereby driving the adjusting rod 33 and the L-shaped plate 31 to move, pushing the fully adsorbed sponge board to one side, thereby automatically discharging the saturated sponge board, and then automatically moving the next sponge board from the storage rack 35 to the support rack 30 to achieve dust adsorption.

[0048] At the same time, after the replacement is completed, the pressing rod 43 is separated from the support plate 42 as the negative pressure cylinder 16 moves. At this time, under the action of the arc extrusion spring 41, the arc rod 39 is pushed to move, so that the adjustment arm 37 is reset to a horizontal state, and the L-shaped plate 31 is driven to reset, which is convenient for the placement of the next sponge board.

[0049] The rest of the structure is the same as that of Example 1.

[0050] Example 3

[0051] See also Figure 5 This embodiment further illustrates other embodiments. The storage rack 35 shown in the figure includes a storage frame 44, which is fixed on the support plate 19 through a bottom bracket, and a plurality of sponge boards are placed in sequence in the storage frame 44.

[0052] It should be noted that: multiple sponge boards are placed in sequence in the storage rack 35. After the L-shaped board 31 pushes the saturated sponge board away, the existence of the L-shaped board 31 prevents the sponge board from moving downward. After the L-shaped board 31 is reset, the multiple sponge boards automatically fall into the support rack 30 due to their own gravity.

[0053] It should also be noted that: the L-shaped plate 31 can not only push the saturated sponge board out, but also prevent other sponge boards from falling prematurely during the process of pushing the saturated sponge board out, making the replacement of the sponge board more convenient. At the same time, personnel need to regularly add sponge boards to the storage rack 35.

[0054] The rest of the structure is the same as that of Example 2.

[0055] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
