[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] In an exemplary embodiment of the present disclosure, a high-pressure steel pipe sealing ring replacement auxiliary device is provided, such as Figure 1 As shown, Figure 1 is a schematic diagram showing the structure of a high-pressure steel pipe sealing ring replacement auxiliary device according to an exemplary embodiment; Figure 2 According to an exemplary embodiment, Figure 1 The middle is an enlarged view of part A showing the structure of the mobile component. Figure 1 and Figure 2 Provide explanation.
[0025] Some specific implementation modes described below are intended to facilitate those skilled in the art to understand the present embodiment, and the present embodiment is not limited to some specific implementation modes described below.
[0026] Reference Figure 1 and Figure 2 An exemplary embodiment of the present disclosure provides a high-pressure steel pipe sealing ring replacement auxiliary device, the high-pressure steel pipe sealing ring replacement auxiliary device comprising:
[0027] There are at least two locking ends 1, which are used to fix and connect the steel pipes;
[0028] There are at least two buckle and pull ends 2, and the buckle and pull ends 2 are used to be engaged with the locking end 1 in a first direction or a second direction, and the first direction is opposite to the second direction;
[0029] The moving component 3 has at least two moving ends 32 for respectively fixing and connecting the two buckling ends 2. The two moving ends 32 can at least maintain a first spacing and a second spacing, and the first spacing and the second spacing are different.
[0030] For example, refer to Figure 1 and Figure 2 There are two locking ends 1, and the locking end 1 includes a clamp 11 adapted to the outer wall of the steel pipe and used to buckle the steel pipe. The clamp 11 is a two-piece hinged design and connected by bolts. After the clamp 11 is opened, it can be detached from the steel pipe or tightly buckled on the outer wall of the steel pipe in two opposite semi-annular structures. The two clamps 11 are coaxially arranged and used to buckle two different steel pipes with openings arranged opposite to each other. The first direction is the opening direction of one of the two steel pipes with opposite openings, that is, Figure 1 The second direction is the direction of the opening of the other of the two steel pipes with opposite openings, that is, Figure 1 Y direction shown.
[0031] There are two buckle and pull ends 2, which include a lifting hook 21 for hooking the locking end 1. The two lifting hooks 21 are both horizontally placed, and the hook-shaped area openings of the two lifting hooks 21 are arranged opposite to each other. The two lifting hooks 21 are respectively adapted to the two clamps 11 and are respectively hooked on the outer walls opposite to each other of the two clamps 11.
[0032] There are two mobile ends 32, which are respectively located at two opposite ends of the mobile component 3. The mobile component 3 is in the shape of a long straight rod arranged along the axis direction of the hoop 11, and the two mobile ends 32 are respectively fixed to the two lifting hooks 21. In this embodiment, for example, the first spacing is Bcm, and the second spacing is B+5cm. When the second spacing is maintained between the two mobile ends 32, the two lifting hooks 21 are disconnected from the two hoop 11, and the two lifting hooks 21 and the mobile component 3 can move freely; when the first spacing is maintained between the two mobile ends 32, the two lifting hooks 21 are respectively hooked on the two hoop 11, and the mobile component 3 applies tension to the two lifting hooks 21 at the same time, so that the two lifting hooks 21 apply tension (pressure) to the two hoop 11. The two lifting hooks 21 are fixed at the current position under the action of the mobile component 3 and the reaction force of the hoop 11, and the mobile component 3 is tensioned and maintains the current position under the reaction force from the hoop 11 transmitted through the lifting hook 21.
[0033] In this embodiment, the locking ends 1 respectively fix two steel pipes. Under the drive of the moving component 3, the moving end 32 drives the buckle end 2 to move to the outside of the two locking ends 1, and moves toward the locking end 1 under the drive of the moving component 3, and is clamped on the locking end 1. Finally, a tensioning structure that imposes axial and radial limitations on the steel pipes is combined at the connection position of the two adjacent steel pipes. After the user removes the connecting device on the two adjacent steel pipes, the port adaptation posture between the two adjacent steel pipes can also be maintained. The new connecting device can be directly installed without the assistance of multiple people, which reduces labor costs and improves work efficiency.
[0034] In an exemplary embodiment of the present disclosure, referring to Figure 1 and Figure 2 The locking end 1 is provided with a flange 22 for extending into the hook-shaped area of the lifting hook 21.
[0035] For example, refer to Figure 1 and Figure 2 The flange 22 is in the shape of a horizontal plate, one end of the flange 22 is fixedly connected to the outer wall of the hoop 11, and the other end extends in a direction away from the hoop 11. When the lifting hook 21 is hooked on the hoop 11, the flange 22 extends from one side of the hook area of the lifting hook 21 and extends from the other side, and the lifting hook 21 abuts against and hooks the flange 22.
[0036] In this embodiment, the horizontally placed plate-shaped flange 22 can generate more and larger abutment surfaces with the lifting hook 21, exerting a more stable posture support effect on the lifting hook 21, reducing the possibility of the lifting hook 21 tilting and flipping, and enhancing the connection strength between the lifting hook 21 and the clamp 11.
[0037] In an exemplary embodiment of the present disclosure, referring to Figure 1 The moving assembly 3 also includes a telescopic rod 33 fixedly connected to the lifting hook 21, a sleeve 34 coaxially sleeved with the telescopic rod 33, and a driver 35 for driving the telescopic rod 33 to move relative to the sleeve 34 along the first direction or the second direction.
[0038] For example, refer to Figure 1The two ends of the telescopic rod 33 are respectively connected to the sleeve 34 through the two ends of the sleeve 34, and each of the two telescopic rods 33 has an end extending out of the sleeve 34 along the axial direction of the clamp 11, and the ends of the two telescopic rods 33 extending out of the sleeve 34 form a movable end 32, and the driver 35 is fixed at the middle position of the length on the sleeve 34 and extends in the direction away from the sleeve 34. By rotating the sleeve 34 or rotating the driver 35, when the position of the sleeve 34 remains unchanged and only rotates around its own axis, the two telescopic rods 33 can change the length extending out of the sleeve 34 under the action of the thread, so that the two telescopic rods 33 can be extended or shortened synchronously, thereby changing the distance between the two lifting hooks 21 fixed to the movable end 32, so as to achieve the purpose of hooking the two lifting hooks 21 on the clamp 11 at the same time, or disconnecting the two lifting hooks 21 from the two clamps 11 at the same time.
[0039] In an exemplary embodiment of the present disclosure, referring to Figure 1 and Figure 2 The moving assembly 3 also includes a connecting ring 31 movably connected between the telescopic rod 33 and the lifting hook 21 , the telescopic rod 33 can rotate relative to the connecting ring 31 , and the connecting ring 31 can rotate relative to the lifting hook 21 .
[0040] For example, refer to Figure 1 and Figure 2 The end of the telescopic rod 33 extending out of the sleeve 34 is integrally formed with a closed annular structure, and there are two connecting rings 31, which are respectively sleeved in the annular structure at the end of the telescopic rod 33. The opposite ends of the two lifting hooks 21 are integrally formed with a closed annular structure, and the connecting ring 31 sleeved on the end of the telescopic rod 33 is also sleeved inside the annular structure at the end of the corresponding lifting hook 21, so that the end of the lifting hook 21, the connecting ring 31 and the end of the telescopic rod 33 form a chain connection structure.
[0041] In this embodiment, the chain-like link structure formed between the lifting hook 21 and the telescopic rod 33 by the connecting ring 31 can enable the moving component 3 to apply a stable pulling force to the lifting hook 21, and can also form a flexible connection between the lifting hook 21 and the moving component 3. Since the telescopic rod 33 is subjected to the friction force from the connecting ring 31 and the reaction force from the clamp 11 when the sleeve 34 rotates around its own axis, and has a certain posture deflection space, it can reduce the possibility of directly driving the lifting hook 21 and the clamp 11 to twist through the telescopic rod 33 when the sleeve 34 rotates around its own axis by rotating the driver 35, thereby reducing the torque on the lifting hook 21 and the clamp 11 when the telescopic rod 33 is extended and retracted, thereby improving the stability in use.
[0042] In an exemplary embodiment of the present disclosure, referring to Figure 1 and Figure 2The driver 35 includes a ratchet 353 coaxially fixedly connected to the sleeve 34, a ratchet control wheel 352 coaxially rotatably connected to the sleeve 34 and adapted to the ratchet 353, and a handle 351 for driving the ratchet control wheel 352 to rotate.
[0043] For example, refer to Figure 1 and Figure 2 The ratchet 353 is coaxially fixedly connected to the sleeve 34, the ratchet control wheel 352 is coaxially sleeved on the sleeve 34 and adapted to the ratchet 353, one end of the handle 351 is fixedly connected to the ratchet control wheel 352, and the other end extends away from the sleeve 34 along the axial direction perpendicular to the hoop 11.
[0044] In this embodiment, the ratchet teeth of the ratchet wheel 353 are designed so that the handle 351 can drive the sleeve 34 to rotate around its own axis within a fixed rotation angle range, thereby reducing the space required for the handle 351 to rotate and also reducing labor intensity.
[0045] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
