The fixing unit comprises at least two arc-shaped sections and a fixing component. For example, the securing unit may include 2-4 arc segments and securing components.

In this embodiment, the fixing unit may include a first arc-shaped segment 11, a second arc-shaped segment 12 and a fixing component as shown in fig. 1, and the first arc-shaped segment 11 and the second arc-shaped segment 12 are sequentially connected end to end by the fixing component and constitute an annular fixing mechanism which is fixed on the pipe body of the pipeline to be operated.

The first arc-shaped section 11 and the second arc-shaped section 12 are connected to form a circular ring structure as shown in fig. 1, so as to be buckled on a pipe body of a pipeline to be operated, but the first arc-shaped section 11 and the second arc-shaped section 12 can also form a similar circular ring structure after being connected, and the circular ring structure is not limited to the circular ring structure in fig. 1. As shown in fig. 1, the first arc segment 11 and the second arc segment 12 may be semi-circular or semi-circular-like ends, respectively, but should not be limited thereto, for example, the first arc segment 11 may be a major arc segment, and the second arc segment 12 may be a minor arc segment, as long as the first arc segment 11 and the second arc segment 12 are connected to form a circular ring or a circular ring-like structure.

As shown in fig. 1, two ends of the first arc-shaped segment 11 and the second arc-shaped segment 12 may extend outward in a radial direction to form a pair of slots, and the pair of slots may include a bearing slot a and an adjusting slot b as shown in fig. 1. The bearing clamping groove a is matched with the adjusting clamping groove b and can be connected with two ends of the first arc-shaped section 11 and the second arc-shaped section 12 through a fixing component. As shown in fig. 1, two ends of the first arc-shaped section 11 are both formed with a bearing slot a, and two ends of the second arc-shaped section 12 are both formed with an adjusting slot b; of course, the invention is not limited thereto, as long as the clamping grooves at the contacting end portions of the first arc-shaped section and the second arc-shaped section can be paired, and for example, a bearing clamping groove may be formed at one end of the first arc-shaped section, an adjusting clamping groove may be formed at the other end of the first arc-shaped section, an adjusting clamping groove may be formed at one end of the second arc-shaped section, and a bearing clamping groove may be formed at the other end of the second arc-shaped section.

Exemplary embodiment 3

On the basis of the above exemplary embodiments 1 or 2, the adjusting unit may include two sets of ratchet assemblies, each of which may include a mount 211 and a ratchet set 212 as shown in fig. 2.

Wherein, the mounting seat 211 is fixedly connected with the fixing unit 1. The mounting seat 211 can be detachably connected to the fixing unit 1, and when the mounting seat needs to be used on another pipeline with different pipe diameters, the mounting seat can be detached and connected to another matched fixing unit 1. Of course, the mounting seat 211 can also be fixed to the ring of the fixed unit 1 by means of the connecting plate 215, for example by welding the connecting plate 215 to the ring of the fixed unit 1, and then connecting the mounting seat 211 to the connecting plate 215 (for example by means of a screw-threaded removable connection, as well as a connection fixed by welding).

As shown in fig. 2, the ratchet group 212 includes a ratchet shaft 2122 and two ratchets 2121, and the ratchets 2121 are mounted in the mount 211 by the ratchet shaft 2122. Two ratchets 2121 are respectively installed to both ends of the ratchet shaft 2122, and a rope can be connected to the ratchet shaft 2122 and wound up and tightened to the ratchet shaft 2122 or the ratchet shaft 2122 for releasing.

In this embodiment, as shown in fig. 2, the ratchet assembly 21 may further include a pawl set 213 and a check set 214.

The pawl set 213 comprises a pawl shaft 2132 and two pawls 2131, and the pawls 2131 are installed in the mounting seat 211 through the pawl shaft 2132. The pawls 2131 are equal in number and correspond to the ratchet wheels 2121 one by one, and each pawl 2131 is engaged with a corresponding ratchet wheel 2121. The two pawls 2131 are respectively attached to both ends of the pawl shaft 2132.

Check 214 limits the rotation of pawl 2131 or check 214 limits the rotation of pawl 2131, including check shaft 2141 and check pawl 2142. Check pawl 2142 is mounted in mounting seat 211 by a check shaft 2141, check pawl 2142 is formed at one end with a check tooth 2142b (e.g., two check teeth 2142b as shown in fig. 3), check tooth 2142b is engageable with pawl 2131, and check handle 2142a is formed at the other end of check pawl 2142. A check shaft 2141 is connected to the mount 211 and may be disposed parallel to the pawl shaft 2132.

As shown in fig. 4, the check shaft 2141 may include a bolt 2141a and a nut 2141b, the bolt 2141a being disposed on the mount 211, the nut 2141b fixing the bolt 2141 a. Check pawl 2142 is connected to the check shaft 2141. As shown in fig. 2, a rotating nut 2133 may be attached to both ends of the pawl shaft 2132, and the rotating nut 2133 may be used to fix the pawl shaft 2132.

The non-return group 214 is arranged to be matched with the pawl group 213, so that the ratchet 2121 and the pawl 2131 can only rotate in one direction, and the rope cannot be loosened by itself after being wound on the ratchet shaft 2122, so that the installation device cannot slide down when being installed on a slope pipeline, and the safety of operators and equipment is ensured.

In the present embodiment, as shown in fig. 2, the check group 214 may further include a fixing plate 2143 and an elastic member 2144.

As shown in fig. 3, a fixing plate 2143 is provided on the check shaft 2141, a stopper 2143b is provided on the top of the fixing plate 2143, and the stopper 2143b can press the check pawl 2142; the fixing plate 2143 may also be formed at the middle thereof with a kidney-shaped through hole 2143a as shown in fig. 5, and the check shaft 2141 passes through the kidney-shaped through hole 2143a in the fixing plate 2143.

One end of the elastic member 2144 is disposed on the mounting seat 211, and the other end is connected to the lower end of the fixing piece 2143. For example, a circular through hole 2143c as shown in fig. 5 is provided at the lower end of the fixing plate 2143, and the other end of the elastic member 2144 is coupled to the circular through hole 2143 c. The elastic member 2144 connects the fixing piece 2143 to the mounting seat 211, and the fixing piece 2143 and the check pawl 2142 are engaged together by the stopper pieces 2143 b.

In the process of installing the heavy split beveling machine, if the tightening or loosening of the rope needs to be limited, the winding direction of the rope on the ratchet shaft 2122 is combined. For example, clockwise rotation of the ratchet 2121 (while the pawl 2131 rotates counterclockwise) releases the cord, and counterclockwise rotation of the ratchet 2121 (while the pawl 2131 rotates clockwise) retracts the cord.

For example, as shown in fig. 3, when check handle 2142a of check pawl 2142 is in the upward position, check tooth 2142b on the upper portion of check pawl 2142 meshes with the gear of pawl 2131; the pawl 2131 can only rotate counterclockwise and the ratchet 2121 can only rotate clockwise, and the cable can only be released on the ratchet shaft 2122. When the pawl 2131 rotates counterclockwise, the non-return pawl 2142 drives the fixing plate 2143 to move, so that the elastic member 2144 stretches, and after the pawl 2131 rotates to a certain extent (for example, one tooth), the elasticity of the elastic member 2144 urges the non-return pawl 2142 to return to the original position, that is, the position where the non-return tooth 2142b on the upper portion of the non-return pawl 2142 engages with the gear of the pawl 2131, so as to achieve the purpose of limiting the pawl 2131 from moving clockwise to limit the rope from tightening.

As another example, when check handle 2142a of check pawl 2142 is in the downward position, check teeth 2142b on the lower portion of check pawl 2142 mesh with the gear of pawl 2131; the pawl 2131 can only rotate clockwise and the ratchet 2121 can only rotate counterclockwise, and the cable can only be tightened on the ratchet shaft 2122. When the pawl 2131 rotates clockwise, the non-return pawl 2142 drives the fixing plate 2143 to move, so that the elastic member 2144 compresses, and after the pawl 2131 rotates to a certain extent (for example, one tooth), the elasticity of the elastic member 2144 urges the non-return pawl 2142 to return to the original position, that is, the position where the non-return tooth 2142b at the lower part of the non-return pawl 2142 is engaged with the gear of the pawl 2131, so as to achieve the purpose of limiting the counterclockwise movement of the pawl 2131 to limit the releasing of the rope.

The purpose of only being able to tighten or loosen the cord after it is wound around the ratchet shaft 2122 is achieved by adjusting the position (up or down) of the backstop handle 2142a of the backstop pawl 2142 depending on the direction of winding of the cord around the ratchet shaft 2122.

In addition, as shown in fig. 4, a gasket 2145 may be provided between the fixing plate 2143 and the check pawl 2142, and the gasket 2145 may include two gaskets 2145, and the gasket 2145 may increase a contact area, reduce a pressure, prevent a looseness, protect a part, and fill up an irregularity between the parts.
