Detailed Description
The present utility model will be further described with reference to the accompanying drawings and specific examples, which are not intended to limit the utility model, so that those skilled in the art may better understand the utility model and practice it.
The embodiment of the utility model discloses a spring type suspension device for a flexible vertical pipe, as shown in fig. 1-6, which comprises an upper flat plate 1, a lower flat plate 2, a middle vertical plate 3, springs 4, a spring supporting component and a supporting arm 5, wherein the upper side edge and the lower side edge of the middle vertical plate 3 are respectively fixed on the bottom surface of the upper flat plate 1 and the top surface of the lower flat plate 2, and the upper side edge, the lower side edge and the top surface of the lower flat plate 2 form a frame main body.
The middle part of the frame body is provided with a vertical pipe through hole 6 for the vertical pipe to pass through, three openings are formed in the vertical plate along the circumferential direction, the spring support assembly comprises two support plates 7 and a first spring baffle plate 8, two side edges of the first spring baffle plate 8 are respectively fixed on one side edge of the two support plates 7, and the other side edges of the two support plates 7 are fixed on two side edges of the openings.
The bottom end of the supporting arm 5 is rotatably connected with the two supporting plates 7 through a pin shaft, a second spring baffle plate 9 is arranged on the supporting arm 5, and two ends of the spring 4 respectively lean against between the first spring baffle plate 8 and the second spring baffle plate 9.
The top of the supporting arm 5 is provided with a supporting table 11 and a limiting part 10, the limiting part 10 is propped against the outer edge of the upper flat plate 1 in a free state, and the supporting table 11 is positioned in the vertical pipe through hole 6. The top of the limiting part 10 is higher than the upper flat plate 1, so that the supporting arm 5 can be prevented from being sprung into the vertical pipe through hole 6 by the spring 4.
In the free state, the vertical pipe is not arranged in the vertical pipe through hole 6, or the supporting platform is clamped at the lower edge of the end part of the vertical pipe.
The frame body is in a drum shape and comprises three parts, the parts are fixedly connected through bolts and nuts, and each part is provided with a spring supporting component. Each part occupies one third of the frame body, and the spring support assembly is located in the middle of each part.
The lower plate 2 is provided with bolt holes, and bolts pass through the bolt holes to fix the lower plate 2 and the top ends of the riser channels 12.
The bottom end of the supporting arm 5 is provided with a pin shaft hole, the supporting plate 7 is provided with a positioning hole, and the pin shaft penetrates through the positioning hole and the pin shaft hole to realize the rotary connection of the supporting arm 5 and the supporting plate 7.
