[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0020] See Figs. 1-2 This utility model provides a center positioning structure for the inside of a steam pipe, comprising:

[0021] Two sleeves 1 are symmetrically arranged. Each sleeve 1 is a semi-circular ring. Both ends of each sleeve 1 are fixedly connected to ear plates 11. When the two sleeves 41 cooperate with each other, they can form a ring, which is fitted on the outside of the inner pipe of the steam pipe.

[0022] Fixed plates 2 are paired together to form a fixed plate group. Several fixed plate groups are evenly arranged around the outer surface of the sleeve 1. One end of each fixed plate 2 is fixedly connected to the outer wall of the sleeve 1. Rollers 21 are rotatably connected to the ends of two fixed plates 2 in the same fixed plate group away from the sleeve 1. The rollers 21 are located between the two fixed plates 2 in the same fixed plate group. Rotating shafts are fixedly connected to the side walls of both ends of the rollers 21. The rotating shafts are rotatably connected to the fixed plates 2 in a one-to-one correspondence (such as bearing connection), so that the rollers 21 and the fixed plates 2 can rotate relative to each other, thereby reducing the friction between the fixed plates 2 and the outer pipe of the steam pipe.

[0023] See Figs. 1-2 Preferably, reinforcing plates 3 are fixedly connected to the side walls of the fixing plate 2, and the ends of the reinforcing plates 3 are fixedly connected to the sleeve 1. The reinforcing plates 3 can improve the strength of the fixing plate 2 and reduce the risk of deformation under external forces.

[0024] See Figs. 1-2 Preferably, the user can add a barrier gasket between the sleeve 1 and the inner pipe of the steam pipe. The barrier gasket can serve as heat insulation and also prevent hard friction between the sleeve 1 and the inner pipe of the steam pipe from causing damage to the inner pipe of the steam pipe.

[0025] See Figs. 1-2 As another embodiment of this utility model, it also includes:

[0026] Auxiliary seat 4, which is detachably connected to the outer surface of the sleeve 1 (for example, screwing, bolting and the like), a plurality of auxiliary seats 4 are uniformly arranged on the outer surface of the sleeve 1.

[0027] The base 5 is matched with the auxiliary seat 4 one by one, and the base 5 is arranged at the middle of the side of the auxiliary seat 4 away from the sleeve 1. The base 5 and the auxiliary seat 4 can be connected in an integral molding manner or a detachable connection manner (for example, screwing, bolting and the like). The side wall of the base 5 away from the auxiliary seat 4 is provided with a containing groove, a extension seat 51 is slidably arranged in the containing groove, one end of the extension seat 51 is fixedly connected with a concave seat after penetrating out of the containing groove, a roller 21 is rotatably connected with the concave seat, and a plurality of first springs are arranged between the extension seat 51 and the side wall of the containing groove.

[0028] The connecting plate 6 is rotatably arranged on the two side walls of the extension seat 51, and the end of the connecting plate 6 away from the extension seat 51 is rotatably connected with a movable hook claw 61. A plurality of fixed hook seats 41 are fixedly connected to the side wall of the auxiliary seat 4, and the fixed hook seat 41 can be matched with the movable hook claw 61 to lock the extension seat 51. When the movable hook claw 61 is matched with the fixed hook seat 41, the first spring is always in a compressed state.

[0029] The locking seat 7 is symmetrically arranged on the two sides of the base 5, and the locking seat 7 is slidably connected to the auxiliary seat 4. The locking seat 7 can reciprocally slide along the auxiliary seat 4. A plurality of locking holes are arranged on the side wall of the auxiliary seat 4, and the locking seat 7 and the locking hole are connected through a locking pin 71, so as to limit the movable hook claw 61.

[0030] Referring to Figs. 1-2 Figs. 1-2 Preferably, the locking pin 71 can be a smooth pin rod, and the locking pin 71 and the locking seat 7 are connected through a second spring. When the second spring is in a natural state, the locking pin 71 is matched with the locking hole. The locking pin 71 can also be a screw rod, and the locking pin 71 and the locking seat 7 are connected through a thread.

[0031] In the implementation process of the utility model, the user matches the sleeve 1 with each other and arranges the sleeve 1 outside the inner pipe (or the blocking pad) of the steam pipeline. The corresponding ear plates 11 are connected through bolts (or other connecting structures). At this time, the plurality of rollers 21 abut against the outer pipe of the steam pipeline, and then the sleeve 1 is pushed to the inside of the steam pipeline, so as to realize the center positioning and support of the steam pipeline.

[0032] As another embodiment of the utility model, when the distance between the roller 21 and the sleeve 1 needs to be adjusted, first make the locking pin 71 cooperate with the locking hole, then move the locking seat 7, make it not abut the movable hook claw 61 and the connecting plate 6, adjust the position of the movable hook claw 61, make it cooperate with the fixed hook seat 41 in the appropriate position, when the movable hook claw 61 cooperates with the fixed hook seat 41, it can hinder the extension seat 51 moving away from the base 5 (the first spring is always in compression state), then move the locking seat 7, make it abut the connecting plate 6 and the movable hook claw 61, then make the locking pin 71 cooperate with the locking hole, at this time, the connecting plate 6 and the movable hook claw 61 can be limited, since the connecting plate 6 is a rigid plate (it has certain deformation ability, but the deformation ability can be ignored), therefore, it can hinder the extension seat 51 moving towards the base 5, thereby realizing the locking of the distance between the roller 21 and the sleeve 1.

[0033] The utility model provides a center positioning structure for inside of steam pipeline, and its beneficial effects are as follows:

[0034] 1. By setting sleeve, fixed plate and roller, the steam pipeline can be centrally positioned and supported, avoiding deformation of the steam pipeline during use or transfer, prolonging the service life of the steam pipeline.

[0035] 2. By setting base, extension seat and connecting plate, the distance between the roller and the sleeve can be adjusted, the application range of the device is expanded, the position of the roller can be locked, avoiding misoperation, and the safety of the device is improved.

[0036] In summary, the utility model has the beneficial effects that the steam pipeline can be centrally positioned to avoid deformation, and the position of the roller can be adjusted and locked, expanding the application range of the device.

[0037] Of course, the utility model can have various embodiments, and those skilled in the art can make corresponding changes and modifications according to the utility model without departing from the spirit and essence of the utility model, but these corresponding changes and modifications should belong to the protection scope of the claims attached to the utility model.
