Referring to fig. 1, the pipe supporting device provided by the application includes a mounting plate 10, a diameter-variable wheel 20 and a fixing member (not shown), the diameter-variable wheel 20 is rotatably disposed on the mounting plate 10, a through hole 11 is formed in the mounting plate 10, a fixing hole 21 is formed in a side surface of the diameter-variable wheel 20, the diameter-variable wheel 20 is rotatable until the fixing hole 21 passes through the through hole 11, and at this time, the fixing hole 21 corresponds to an opening direction of the through hole 11, so that the fixing member can be sequentially disposed in the through hole 11 and the fixing hole 21.
The circumference of the diameter-variable wheel 20 is an arc surface, and the pipe can be placed in the space formed by the circumference of the top end of the diameter-variable wheel 20. In addition, the circumferential surface of the reducing wheel 20 is gradually changed in size along the circumferential direction of the reducing wheel 20, so that the size of the top circumferential surface of the reducing wheel 20 is gradually changed, for example, the depth and the radian are continuously increased in the process of rotating the reducing wheel 20, and the top of the reducing wheel 20 can be put down and support pipes with different sizes by rotating the reducing wheel 20.
The mounting plate 10 is used for mounting the diameter-variable wheel 20, and simultaneously when the through hole 11 is aligned with the fixing hole 21, the fixing piece can be sequentially inserted into the through hole 11 and the fixing hole 21, so that the rotation of the diameter-variable wheel 20 is limited, and the unstable support caused by the rotation of the diameter-variable wheel 20 in the supporting process is prevented.
The number of the fixing holes 21 is at least two, and circumferentially arranged at the side of the reducing wheel 20. When the reducing wheel 20 rotates, each fixing hole 21 can pass through the position of the through hole 11. Different fixing holes 21 can be used for correspondingly supporting pipes with different sizes by selecting different fixing holes 21 to align with the through holes 11 and fixing the pipes by adopting fixing pieces, and the reducing wheels 20 can be used for preventing the pipes from being thrown outwards in the supporting process.
The size adaptation of mounting and fixed orifices 21 prevents that the mounting from rocking in fixed orifices 21 influences fixed effect. In some embodiments, the fixing member may be selected as a screw, and the fixing hole 21 may be provided as a threaded hole, so that the fixing member and the fixing hole 21 are fixed by screw-fitting.
Further, an adjusting space for sliding the fixing member is formed in the through hole 11, and the sliding direction of the fixing member is parallel to the side surface of the reducing wheel 20.
In the adjustment process of the reducing wheel 20, when the positions of the through holes 11 are fixed and the number of the fixing holes 21 on the reducing wheel 20 is limited, the adjustment range of the reducing wheel 20 is smaller. Through forming the regulation space in through-hole 11, make things convenient for the mounting to aim at fixed orifices 21 in through-hole 11 more, simultaneously because the fixed position of mounting can adjust, and then can finely tune reducing wheel 20's fixed angle, enlarge reducing wheel 20 and support the size scope of tubular product.
For example, 5 fixing holes 21 are formed in the reducing wheel 20, and the corresponding pipes are 10, 20, 30, 40 and 50, when the pipe is 42, the reducing wheel 20 can be rotated at the position corresponding to the original size 40 by a certain angle, then the fixing piece is moved in the through hole 11 to the position where the fixing holes 21 are located, and the reducing wheel 20 is fixed, so that the pipe with the size 42 is supported.
Specifically, the cross-sectional shape of the through hole 11 is an arc shape. The arc corresponds to the circular arc formed by the plurality of fixing holes 21, so that the fixing piece can move along the arc, and the fixing piece is easier to align with the position of the fixing hole 21 on the reducing wheel 20.
In some embodiments, the mounting plate 10 includes a connecting plate and side plates fixed on two sides of the connecting plate, the reducing wheel 20 is rotatably disposed between the two side plates, the two sides of the reducing wheel 20 are provided with fixing holes 21, the two side plates are provided with through holes 11, and the number of fixing pieces is two.
The diameter-variable wheel 20 is mounted by the two side plates, so that the diameter-variable wheel 20 can be mounted more firmly. Meanwhile, the fixing piece can fix the reducing wheel 20 from two sides, so that the fixing of the reducing wheel 20 is more stable.
In addition, referring to fig. 1 and 2, the pipe supporting device further includes a rotating shaft 31 and a bearing 32, the rotating shaft 31 is disposed between the two mounting plates 10, the reducing wheel 20 is disposed on the rotating shaft 31, the bearing 32 is added at two ends, and the bearing 32 is clamped by a shaft retainer ring, so that the reducing wheel 20 can rotate around the rotating shaft 31.
Further, the pipe supporting device further comprises a lifting assembly 40, and the mounting plate 10 is arranged at the lifting end of the lifting assembly 40.
The lifting assembly 40 is used for driving the mounting plate 10 to lift and adjust the height of the reducing wheel 20, so that the center of the pipe on the reducing wheel 20 is consistent with the center of the front chuck and the rear chuck, and the clamping of the front chuck and the rear chuck and the same level of three parts supported by the reducing wheel 20 in the supporting process of the pipe can be ensured.
In some embodiments, the lifting assembly 40 includes a bracket 41, a lifting cylinder 42, and a lifting rail 43, the lifting rail 43 is disposed on the bracket 41, the mounting plate 10 is slidably disposed on the lifting rail 43 in a vertical direction, and a piston rod of the lifting cylinder 42 is connected to the mounting plate 10.
