Description

Technical Field

[0001] The utility model relates to a fog cannon, in particular to a horizontal rotation guide limiting mechanism of a fog cannon. Background Art

[0002] In a curved pipe fog cannon, the air outlet pipe is a curved pipe. When the angle of the air outlet pipe needs to be adjusted, it is generally controlled by a hydraulic cylinder. In the current structure, the hydraulic cylinder controls the adjustment angle of the air outlet pipe. Since most of the air outlet pipes only need to control the pitch angle, only the pitch guidance is required. However, in some special fog cannons, especially those that use bellows as intermediate air guides, a certain amount of rotational movement in the horizontal direction is required. The current horizontal guiding mechanism is to add a rotary drive system to the base of the fog cannon to achieve horizontal adjustment. The structure is complex and requires the addition of a drive system that can only achieve horizontal rotation. However, it is still impossible to make the necessary three-dimensional angle adjustment to the split air outlet direction, and it is costly and bulky. Utility Model Content

[0024] Example:

[0025] like Figure 1 As shown, a horizontal rotating guide and limit mechanism of a fog cannon includes an air inlet pipe 1 and an air outlet pipe 2, wherein the air inlet pipe 1 and the air outlet pipe 2 are connected via a bellows 6, and include a hinge 3 for connecting the air inlet pipe 1, and a guide and limit member 4 provided on the air outlet pipe 2; since the bellows 6 has a high degree of freedom, the air outlet pipe 2 can make a pitching motion at the hinge point of the hinge 3, and at the same time, can make a horizontal twisting motion along the guide and limit member 4, so as to adjust the air outlet direction and angle of the air outlet pipe 2.

[0026] like Figure 2 Shown is Figure 1 The partially enlarged schematic diagram shows that the guide limit member 4 includes a first side plate 41 and a second side plate 42 fixed to the air outlet duct 2, the first side plate 41 and the second side plate 42 are both provided with a guide groove 45, the first side plate 41 and the second side plate 42 are provided with a slider device, the slider device includes a slider 47 and a guide rod 48, the sliding end of the slider device extends into the guide groove 45 through the guide rod 48, and the fixed end is fixedly connected to the hinge 3, so that the air outlet duct 2 can do both pitch motion with the hinge 3 as the center, and can do horizontal rotation motion along the guide groove 45.

[0027] Specifically, the first side plate 41 and the second side plate 42 are both arc-shaped and fit the outer wall of the air outlet duct, and the outer wall is fixed with a guide bar 46, the guide bar 46 is located on the side of the guide groove 45, and the guide rod 48 is provided with a hook bar 483, and the hook bar 483 hooks the guide bar 46. When the air outlet duct is twisted in the horizontal direction, the first side plate 41 and the second side plate 42 and the guide bar 46 are twisted horizontally accordingly. At this time, the slider 47 remains in its original position and moves relative to the two side plates. Under the action of the guide groove 45 and the guide rod 48, the movement remains stable, and the hook bar 483 and the guide bar 46 can further ensure the smooth movement.

[0028] like Figure 3 The figure shows a schematic diagram of a slider, wherein the slider 47 comprises a main board 471, a connecting piece 473 fixed to the main board 471, and a supporting piece 472 fixed to the main board 471. The main board 471 is located between the first side panel 41 and the second side panel 42, and the supporting piece 472 is between the first side panel 41 and the second side panel 42. The connecting piece 473 is fixedly connected to the hinge 3 by bolts 5, and the guide rod 48 is fixed to the main board 471. The main board 471 plays a supporting and installation role, and the supporting piece 472 can play a supporting role, and can be stable between the two side panels without deflecting to one side. The connecting piece 473 plays a fixed connection role, and is fixedly connected with two bolts, which is more stable and easy to disassemble.

[0029] The guide rod 48 includes a main rod 481, a bent section 482 fixed to one end of the main rod 481, and a hook strip 483 fixed to the bent section 482. The hook strip 483 is parallel to the main rod 481. The main rod 481 is provided with a first fixing hole 484 for connecting to the second fixing hole 49 of the main board 471. The main rod 481, the bent section 482, and the hook strip 483 form a hook shape, which can guide in the guide groove and enhance stability to prevent separation.

[0030] like Figure 2 As shown, support plates 43 are fixed at both ends of the first side plate 41 and the second side plate 42, and the two limit plates 44 are located between the two support plates 43. The length of the first side plate 41 and the second side plate 42 is greater than the length of the guide, making the entire guide limiter 4 more stable.

[0031] Two limit plates 44 are further provided between the first side plate 41 and the second side plate 42. The slider 47 is located between the two limit plates 44 and is used as a limit. Since the torsion of the corrugated tube in the horizontal direction has certain limitations, the limit plates are provided to prevent excessive torsion and protect the safety of the corrugated tube.

[0032] like Figure 2 As shown, the hinge 3 includes two lower pieces 31 and two upper pieces 34. The two lower pieces 31 are fixedly connected by a lower plate 33 to form an upper hinge part, and the two upper pieces 34 are fixedly connected by an upper plate 36 to form a lower hinge part. The upper hinge part and the lower hinge part are connected by a hinge shaft 37; the lower extension sections 32 of the two lower pieces 31 are fixedly connected to the air inlet pipe 1, and the upper extension sections 35 of the two upper pieces 34 are fixedly connected to the air outlet pipe 2.

[0033] Working principle:

[0034] The air outlet pipe 2 is controlled in pitch and horizontal twist by a hydraulic cylinder (not shown);

[0035] When the air outlet pipe 2 pitches, it moves with the hinge 3 as the axis;

[0036] When the air outlet pipe 2 is twisted horizontally, the slider 47 keeps its position, and the guide groove moves with the horizontal twisting of the air outlet pipe. The slider 47 and the guide groove move relative to each other to achieve a guiding effect. At the same time, the limit plate can prevent excessive twisting.

[0037] The above description is only a preferred implementation mode of the present invention, and does not limit the present invention in any form. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of the technical solution of the present invention.
