Description

Technical Field

[0001] The invention belongs to the technical field of dust suppression canopies, and in particular relates to a dust suppression canopy system. Background Art

[0002] In recent years, with the increasing attention paid to air pollution prevention and control, the requirements for dust control at construction sites have become increasingly higher. Dust control is very necessary. Many construction sites use manual dust nets to cover bare soil, which is time-consuming and labor-intensive. In order to solve the dust problem of earthwork during construction, a canopy system was adopted, in which the curtain net has a fast opening and closing speed, saves time and effort, is both beautiful and can prevent dust.

[0003] It was found during use of the existing canopy system that the canopy is unfolded by pulling the sliding seat on which the canopy is installed. During the sliding process of the sliding seat, some sliding seats move different distances due to different friction forces, which causes the canopy to be in a state of alternating straightness and bending. At this time, the aesthetics and dust suppression effect of the canopy are not good. In addition, in windy weather, the canopy is fixed by pull ropes, so the overall stability of the canopy is not strong. When the pull ropes break, the canopy as a whole will shift, thereby affecting the dust suppression effect.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0024] A first protrusion is provided on the slide and a second protrusion is installed at the bottom of the slide, wherein the heights of the second protrusion and the first protrusion are different.

[0056] like Figure 1 and Figure 2 As shown, further, several pairs of reinforcing ribs 211 are installed between the beams 2, and the several pairs of reinforcing ribs 211 are all in an inclined state. The reinforcing ribs 211 can improve the stability between the two pairs of beams 2. Jackets 21 are installed on both sides of the beams 2. The jackets 21 are clamped on the side walls of the supporting columns 1. Locking bolts are screwed on the jackets 21, and the locking bolts are screwed on the supporting columns 1. The jackets 21 facilitate disassembly and assembly at a later stage, making the operation simpler.

[0057] Embodiment 2, based on the above embodiment and the difference between this embodiment and the present embodiment is: Figure 2 , Figure 3 and Fig. 9 As shown, a locking plate 31 is welded on the side wall of the slide plate 3, and the locking plate 31 is screwed on the top of the cross beam 2 by bolts.

A limiting seat 35 is installed on the side wall of the slide plate 3, and the limiting seat 35 is placed on both sides of the positioning rail 33. When the slide seat 4 slides, the positioning rail 33 guides the sliding of the slide seat 4, and the limiting seats 35 on both sides of the positioning rail 33 serve the purpose of limiting, mainly to prevent falling off.

[0058] like Figure 3 , Fig. 9 , Fig.10 and Fig.11 As shown, in a specific embodiment, a guide track 32 is provided on the outer side of the slide 3, a mounting plate 41 is installed on the side wall of the slide 4, a guide wheel 411 is rotatably installed on the mounting plate 41, and the guide wheel 411 is slidably arranged on the guide track 32. A positioning rod 36 is installed on the side of the slide 3 away from the hoisting motor 6, and the positioning rod 36 is connected to the end of the dust suppression curtain net 422, and the dust suppression curtain net 422 is wavy, and the dust suppression curtain net 422 is a curtain net made of a special anti-aging polyethylene material. When the slide 4 slides, the mounting plate 41 on the side wall of the slide 4 and the guide wheel 411 slide on the guide track 32, and the friction during the sliding process can be reduced by the guide wheel 411.

[0059] like Figure 3 and Figure 4As shown, further, a baffle 511 is installed on the block 51, and the baffle 511 is placed in the internal chamber of the insertion rod 5, a limiting hole 512 is opened on the baffle 511 and the block 51, a limiting rod 521 is inserted in the limiting hole 512, a fixing seat 52 is installed at the end of the limiting rod 521, the fixing seat 52 is installed in the inner cavity of the insertion rod 5, a limiting spring 522 is sleeved on the limiting rod 521, one end of the limiting spring 522 is clamped on the baffle 511, and the other end of the limiting spring 522 is clamped on the fixing seat 52. When the slide seat 4 slides, the pull plate 421 on the slide seat 4 is in a sliding state synchronously, and the insertion rod 5 on the pull plate 421 begins to move toward the insertion hole 531 with a reduced aperture, and drives the block 51 and the baffle 511 to slide along the limit rod 521 through the inclined surface of the block 51. At this time, the baffle 511 can compress the limit spring 522 until the block 51 passes through the insertion hole 531. At this time, the limit spring 522 pushes the block 51 outward again, thereby achieving the purpose of the clamping.

[0060] Embodiment 3, based on the above embodiment and the difference between this embodiment and the present embodiment is: Figure 2 and Figure 5 As shown, the base of the hoisting motor 6 is installed with a mounting seat 61, and the mounting seat 61 is installed with a sliding sleeve 611, the sliding sleeve 611 is slidably sleeved on the supporting column 1, and a bolt is installed between the sliding sleeve 611 and the supporting column 1, and the rotation center of the hoisting roller 62 is installed with a rotating shaft 621, the rotating shaft 621 and the output shaft of the hoisting motor 6 are connected to each other, and the pull rope 63 is overlapped on the directional wheel 631 installed on the side wall of the fixed plate 53. The output shaft of the hoisting motor 6 can drive the rotating shaft 621 to rotate, and the hoisting roller 62 on the rotating shaft 621 starts to rotate, and the hoisting roller 62 can wind the pull rope 63, and the pull rope 63 can complete the reversing operation through the directional wheel 631.

[0061] like Figure 2 and Figure 6As shown, in a specific embodiment, a partition 711 is slidably arranged inside the positioning sleeve 7, the top of the partition 711 and the pull rod 71 are interconnected, the bottom of the partition 711 and the extrusion rod 83 are interconnected, and a return spring 712 is arranged on the screw sleeve of the extrusion rod 83, one end of the return spring 712 is clamped on the inner wall of the positioning sleeve 7, and the other end of the return spring 712 is clamped on the partition 711. During the rotation of the hoisting roller 62, the thickness of the pull rope 63 inside the hoisting roller 62 gradually increases. The thickness of the pull rope 63 can squeeze the pressure block 731 at the bottom and press it downward. The pressure block 731 can drive the synchronous bracket 73 at the bottom to slide downward. The synchronous bracket 73 drives the pull rod 71 to slide downward. The partition 711 at the bottom of the pull rod 71 moves downward synchronously, and can be reset by the reset spring 712. When the pull rod 71 slides, the synchronous bracket 73 on the pull rod 71 drives the card plates 721 on both sides to move downward. At this time, the card plates 721 can block a part of the hole 531, thereby achieving the purpose of reducing the size of the hole 531.

[0062] like Figure 7 and Figure 8 As shown, further, a through hole 81 is provided at the bottom of the protective sleeve 8, a clamping shaft 822 is installed on the through hole 81, the clamping shaft 822 is rotatably connected with the rocker arm 82, a U-shaped plate 833 is installed on the rocker arm 82, a sliding rod 832 is slidably arranged in the cavity between the U-shaped plate 833 and the rocker arm 82, arch brackets 831 are installed at both ends of the sliding rod 832, and an extrusion rod 83 is installed on the top of the arch bracket 831. When the pull rod 71 moves downward, the partition plate 711 at the bottom of the pull rod 71 drives the extrusion rod 83 to slide downward, and the extrusion rod 83 drives the arch bracket 831 at the end to slide downward, and the sliding rod 832 on the arch bracket 831 slides in the gap surrounded by the U-shaped plate 833, pushing the rocker arm 82 to rotate around the clamping shaft 822, and the dust suppression nozzle 821 on the rocker arm 82 moves out from the inside of the protective sleeve 8, releasing the protective function.

[0063] The implementation principle of a dust suppression canopy system of this embodiment is as follows:

[0064] When the canopy needs to be closed, the operator can start the hoisting motor 6, wherein the output shaft of the hoisting motor 6 can drive the rotating shaft 621 to rotate, the hoisting roller 62 on the rotating shaft 621 starts to rotate, the hoisting roller 62 can wind the pull rope 63, and the pull rope 63 can complete the reversing operation through the directional wheel 631, and finally the pull rope 63 is retracted, and the pull rope 63 pulls the pull plate 421 at the end to start moving, and the dust suppression curtain net 422 on the pull plate 421 begins to gradually unfold, and the slide seat 4 on the dust suppression curtain net 422 slides on the slide plate 3.

[0065] When the slide seat 4 slides, the positioning groove 412 on the slide seat 4 slides on the positioning rail 33, and the positioning rail 33 plays a guiding role, and the limit seats 35 on both sides of the positioning rail 33 play a limiting purpose, mainly for the purpose of preventing falling off, wherein the mounting plate 41 and the guide wheel 411 on the side wall of the slide seat 4 slide on the guide rail 32, and the guide wheel 411 can reduce the friction during the sliding process.

[0066] When the slide 4 slides, the second protrusion 43 on the slide 4 can slide synchronously until the second protrusion 43 moves to the corresponding first protrusion 34. At this time, the first protrusion 34 can block the sliding of the second protrusion 43. Fig.11 As shown, when the second protrusion 43 is blocked, the slide 4 corresponding to the second protrusion 43 cannot slide synchronously, and the slide 4 can slide to the specified position at this time, thereby ensuring that the dust suppression curtain net 422 on the slide 4 is in a uniformly expanded state, thereby improving the dust suppression effect of the dust suppression curtain net 422.

[0067] During the rotation of the hoisting roller 62, the thickness of the pull rope 63 inside the hoisting roller 62 gradually increases. The thickness of the pull rope 63 can squeeze the pressure block 731 at the bottom and press it downward. The pressure block 731 can drive the synchronous bracket 73 at the bottom to slide downward. The synchronous bracket 73 drives the pull rod 71 to slide downward. The partition 711 at the bottom of the pull rod 71 moves downward synchronously, and can be reset by the reset spring 712. When the pull rod 71 slides, the synchronous bracket 73 on the pull rod 71 drives the card plates 721 on both sides to move downward. At this time, the card plates 721 can block a part of the hole 531, thereby achieving the purpose of reducing the size of the hole 531.

[0068] When the slide seat 4 slides, the pull plate 421 on the slide seat 4 is in a sliding state synchronously, and the insertion rod 5 on the pull plate 421 begins to move toward the insertion hole 531 with a reduced aperture, and drives the block 51 and the baffle 511 to slide along the limit rod 521 through the inclined surface of the block 51. At this time, the baffle 511 can compress the limit spring 522 until the block 51 passes through the insertion hole 531. At this time, the limit spring 522 pushes the block 51 outward again, thereby achieving the purpose of clamping.

[0069] Therefore, the dust suppression curtain net 422 at this time is not only connected by the pull rope 63, but also has a rigid connection between the insertion rod 5 and the insertion hole 531, which can ensure that the overall stability of the dust suppression curtain net 422 is improved.

[0070] When unlocking in the later stage, it is necessary to drive the hoisting roller 62 to reverse through the hoisting motor 6. At this time, the thickness of the pull rope 63 inside the hoisting roller 62 changes, and the return spring 712 drives the pressure block 731 and the pull rod 71 to move upward smoothly, driving the card plate 721 to slide upward, and the card plate 721 and the socket 531 are separated, so that the socket 531 becomes larger as a whole, and then the card block 51 and the plug rod 5 can be moved out of the socket 531 at this time, achieving the purpose of automatic unlocking. However, when unlocking, the operator needs to pull the slide 4 to slide by himself.

[0071] When the pull rod 71 moves downward, the partition 711 at the bottom of the pull rod 71 drives the extrusion rod 83 to slide downward. At this time, the extrusion rod 83 drives the arch bracket 831 at the end to slide downward, and the sliding rod 832 on the arch bracket 831 slides in the gap surrounded by the U-shaped plate 833 at this time, pushing the rocker arm 82 to rotate around the clamping shaft 822 at this time, and the dust reduction nozzle 821 on the rocker arm 82 is moved out from the inside of the protective cover 8 to release the protective effect. The dust reduction operation is completed by the water mist sprayed by the dust reduction nozzle 821. Therefore, when the pull rope 63 does not pull the dust suppression curtain 422 for covering operation, the dust reduction nozzle 821 is located inside the protective cover at this time, which has a protective effect.
