[0023] The utility model is further described below in conjunction with the accompanying drawings:

[0024] like Figure 1 - Figure 4 As shown, a hard-core rubber hose traction device includes an equipment platform 1, and the upper surface of the equipment platform 1 is provided with limiting mechanisms symmetrically distributed front and back, and a traction mechanism is provided between the limiting mechanisms. The limiting mechanism includes an inner ring 203, and a limiting link 204 is hinged to a circular array on one side of the inner ring 203, and the other end of the limiting link 204 is hinged to a radial sliding plate 205, and the radial sliding plate 205 is slidably connected to a radial sliding sleeve 206. A limiting ring 207 is provided on one side of the inner ring 203, and the limiting ring 207 is fixedly connected to the radial sliding sleeve 206 in a circular array on one side close to the inner ring 203, and a limiting wheel 208 is provided on one end of the radial sliding plate 205 close to the center of the limiting ring 207, and a rotating connection component is provided on the outer side of the inner ring 203.

[0025] The limiting ring 207 is used to connect the radial sleeve 206, and the radial sleeve 206 is used to slide and connect the radial sliding plate 205 to keep the radial sliding plate 205 sliding along the diameter direction. When the inner ring 203 rotates, it drives the movement of the limiting link 204, and then drives the radial sliding plate 205 to move along the diameter direction, thereby realizing the limitation of hard-core rubber hoses of different diameters. At the same time, the rolling contact between the limiting wheel 208 and the hard-core rubber hose is adopted to reduce the wear of the hard-core rubber hose.

[0026] The rotating connection assembly includes an outer ring 201 , the inner part of the outer ring 201 is rotatably connected to the inner ring 203 , the left and right sides of the outer ring 201 are fixedly connected to columns 202 , and the bottom end of the column 202 is fixedly connected to the equipment platform 1 .

[0027] The outer ring 201 is used to maintain the rotation of the inner ring 203 , and the column 202 is used to connect the outer ring 201 and the equipment platform 1 .

[0028] The limiting mechanism includes four vertical sliding columns 209 . The vertical sliding columns 209 are fixedly connected to the left and right sides of the limiting ring 207 . The bottom ends of the vertical sliding columns 209 are fixedly connected to the equipment platform 1 .

[0029] The vertical sliding column 209 is used to connect the limiting ring 207 and the traction mechanism.

[0030] The limiting mechanism includes four adjusting links 301 , one end of the adjusting links 301 is hinged to the inner ring 203 , and a transmission plate 302 is provided on the upper and lower sides of the limiting mechanism. The other end of the adjusting links 301 is hinged to the transmission plate 302 , and the transmission plate 302 is slidably connected to the vertical sliding column 209 .

[0031] The adjusting connecting rod 301 is used to connect the transmission plate 302 and the inner ring 203. When the inner ring 203 is kept rotating, the adjusting connecting rod 301 drives the transmission plates 302 to move closer to or farther from each other.

[0032] The limiting mechanism includes a belt conveyor 303 , and the belt conveyor 303 is installed on the side where the conveying plates 302 are close to each other.

[0033] Driven by the conveying plate 302, the belt conveyor 303 clamps the hard-core rubber hose from the upper and lower sides and pulls the hard-core rubber hose.

[0034] The upper surface of the equipment platform 1 is fixedly connected to the hydraulic cylinder 4, and the top end of the hydraulic cylinder 4 is fixedly connected to the conveying plate 302 at the lower side.

[0035] The hydraulic cylinder 4 controls the lifting and lowering of the lower conveying plate 302 by its own extension and retraction, and then drives the upper conveying plate 302 to rise by adjusting the connecting rod 301 and the inner ring 203, so that the conveying plates 302 and the belt conveyor 303 on the upper and lower sides are close to or away from each other.

[0036] Working principle:

[0037] Put the hard-core rubber hose between the two belt conveyors 303 and pass it through the limit ring 207, then start the hydraulic cylinder 4, which pushes the lower conveying plate 302 to rise, driving the lower adjusting link 301 to push the inner ring 203 to rotate, and the rotation of the conveying plate 302 drives the movement of the limit link 204 and the movement of the upper adjusting link 301, and the upper adjusting link 301 drives the upper conveying plate 302 to descend, thereby driving the two belt conveyors 303 to approach each other and contact the upper and lower sides of the hard-core rubber hose, and starting the belt conveyor 303 can realize the traction of the hard-core rubber hose.

[0038] When the inner ring 203 rotates, it drives the limiting link 204 to push multiple radial sliding plates 205 in a circular array. The radial sliding plates 205 approach the center of the circle along the diameter direction so that the limiting wheels 208 contact the hard core rubber hose. The multiple limiting wheels 208 limit the hard core rubber hose inside and prevent the hard core rubber hose from wearing.

[0039] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
