Description

Technical Field

[0001] This utility model relates to the field of pipeline splicing equipment technology, and in particular to a pipeline splicing device. Background Technology

[0002] Pipe splicing involves fitting two pipe sections together, aligning their ends, and welding them together. To improve splicing efficiency and quality, mechanical connection methods, such as clamp connections and flange connections, have gradually emerged.

[0003] Existing pipe splicing devices, such as the improved fixing structure disclosed in patent publication number CN217513266U, are suitable for welding pipes. This patent uses a first upper fixing plate and a first lower fixing plate to rotate on a first frame via a first rotating shaft, and a second upper fixing plate and a second lower fixing plate to rotate on a second frame via a second rotating shaft. This setting allows the device to adjust the left and right angles, thereby making the splicing of two pipes more seamless and improving the welding quality.

[0004] The first and second upper and lower fixing plates in this patent can only be used for fixing and splicing pipes with a single inner diameter, which has a limited scope of application. When it is necessary to splice pipes with other inner diameters, other splicing methods are required, which increases the cost of pipe splicing to a certain extent.

[0005] Therefore, it is necessary to design a pipe splicing device that can be applied to pipes of different specifications. Utility Model Content

[0006] To address the aforementioned problems, this utility model proposes a pipe splicing device to more accurately resolve these issues.

[0007] This utility model is achieved through the following technical solution:

[0008] This utility model proposes a pipe splicing device, including a first sleeve assembly that sleeves with one pipe and a second sleeve assembly that sleeves with another pipe. Both the first and second sleeve assemblies include a collar, a plurality of inner diameter adjusting members on the collar, and a lifting member disposed at the bottom of the collar. The inner diameter adjusting member includes an adjusting hole opened on the collar, an adjusting screw that cooperates with the adjusting hole, and a strength plate rotatably connected to one end of the adjusting screw and located inside the collar. An elastic body is disposed on the inner side of the strength plate, and limiting members for limiting the movement trajectory of the strength plate are disposed on both sides of the collar.

[0009] Furthermore, the limiting member of this utility model includes limiting rods disposed on both sides of the plate body, a plate body that cooperates with the limiting rods and is connected to the outside of the strength plate, and a limiting groove formed on the plate body for the limiting rods to pass through.

[0010] Furthermore, the first socket assembly is provided with a calibration end on one side, and the second socket assembly is provided with a support base that cooperates with the calibration end.

[0011] Furthermore, the calibration end includes a fixed base connected to the collar, the fixed base having an insertion groove for inserting the calibration rod, and the support base having a groove that cooperates with the calibration rod.

[0012] Furthermore, in this invention, two auxiliary support members are provided at the bottom of the strength plate located below the inner side of the collar.

[0013] Furthermore, the auxiliary support member includes a slot formed at the bottom of the strength plate, a block that cooperates with the slot, and an auxiliary support rod disposed at the bottom of the block. The inner side of the collar and located on both sides of the screw have inner holes that cooperate with the ends of the auxiliary support rod.

[0014] Furthermore, the auxiliary support rod of this utility model includes a fixed rod connected to the locking block, an adjustment groove opened on the fixed rod, and a spring body disposed in the adjustment groove. One end of the spring body is connected to a movable rod. A plurality of first fixing holes are provided through the movable rod. A second fixing hole is opened on the fixed rod to cooperate with the first fixing holes. Locking rods are provided through the first fixing holes and the second fixing holes.

[0015] The beneficial effects of this utility model are:

[0016] The first and second socket components can be connected to two pipes that need to be spliced; the inner diameter adjustment component can be used to clamp and fix pipes of different specifications; the lifting component can be used to adjust the height of the first and second socket components and simultaneously adjust the height of the pipes, thereby ensuring the splicing of the two pipes.

[0017] The limiting rod can connect one end of the plate to the collar, while the limiting groove can move inward synchronously when the strength plate moves inward. The limiting rod can also constrain the force of the strength plate's left and right rotation.

[0018] The setting of the calibration rod and the tank can provide certain alignment reference conditions for the work, which reduces the time spent on pipeline alignment to a certain extent.

[0019] The auxiliary support rod can distribute the force exerted by the pipe on the strength plate below the inner side of the spring, and reduce the gravity on the strength plate and adjusting screw, thereby increasing the service life of the strength plate and adjusting screw to a certain extent.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, of the embodiments of this utility model. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] Example

[0033] refer to Figure 1-10 A pipe splicing device includes a first sleeve assembly 1 that is sleeved with one pipe and a second sleeve assembly 2 that is sleeved with another pipe. Both the first sleeve assembly 1 and the second sleeve assembly 2 include a collar 3, a plurality of inner diameter adjusting members 4 provided on the collar 3, and a lifting member 5 provided at the bottom of the collar 3. The inner diameter adjusting member 4 includes an adjusting hole 41 opened on the collar 3, an adjusting screw 42 that cooperates with the adjusting hole 41, and a strength plate 43 that is rotatably connected to one end of the adjusting screw 42 and located inside the collar 3. An elastic body 44 is provided on the inner side of the strength plate 43, and limiting members 6 are provided on both sides of the collar 3 to limit the movement trajectory of the strength plate 43.

[0034] The first socket assembly 1 and the second socket assembly 2 can be connected to two pipes that need to be spliced; the inner diameter adjustment component 4 can be used to clamp and fix pipes of different specifications; the lifting component 5 can be used to adjust the height of the first socket assembly 1 and the second socket assembly 2, and simultaneously adjust the height of the pipes, thereby ensuring the splicing of the two pipes.

[0035] Specifically, the workers adjust the inner diameter adjusting parts 4 on the first and second sleeve components 1 and 2 respectively. The inner diameter adjusting part 4 located below the inner side of the collar 3 is adjusted first. The workers rotate the adjusting screw 42, which engages with the adjusting hole 41 and pushes the strength plate 43, causing the elastic body 44 to move to a preset position. Next, the workers attach the adjusted first and second sleeve components 1 and 2 to the two pipes respectively, and then adjust the remaining inner diameter adjusting parts 4 in sequence, bringing the elastic body 44 into contact with the outer surface of the pipes to fix them in place. Then, the workers use the lifting component 5 to adjust the height of the pipes, further bringing the ends of the two pipes into contact. Finally, the connection between the two pipes is welded.

[0036] In this embodiment, the limiting member 6 is provided to constrain the left and right movement range of the strength plate 43, so that when the strength plate 43 can be rotated by the adjusting screw 42, it can only move back and forth.

[0037] In this embodiment, reference Figure 10 The connection structure between the adjusting screw 42 and the strength member is as follows: a rotating shaft 421 is fixedly installed on one side of the adjusting screw 42, and a rotating groove 431 that cooperates with the rotating shaft 421 is opened on one side of the strength plate 43. The rotating shaft 421 is convex. When the adjusting screw 42 rotates, it will drive the rotating shaft 421 to rotate in the rotating groove 431. At the same time, due to the presence of the limiting member 6, the strength plate 43 will move towards the inside of the collar 3 due to the rotation of the adjusting screw 42.

[0038] In this embodiment, optionally, refer to Figure 4 The lifting component 5 includes a connecting frame 51 connected to the bottom of the collar 3, and a hydraulic cylinder 52 connected to the bottom of the connecting frame 51.

[0039] Preferred, Reference Figure 3 The limiting member 6 includes limiting rods 61 provided on both sides of the plate body 62, a plate body 62 that cooperates with the limiting rods 61 and is connected to the outside of the strength plate 43, and a limiting groove 63 opened on the plate body 62 for the limiting rods 61 to pass through.

[0040] The limiting rod 61 connects one end of the plate 62 to the collar 3, while the limiting groove 63 allows the strength plate 43 to move inward synchronously. The limiting rod 61 also constrains the force that causes the strength plate 43 to rotate left and right.

[0041] Preferred, Reference Figure 2 and Figure 3The first socket assembly 1 has a calibration end 7 on one side, and the second socket assembly has a support base 8 that cooperates with the calibration end 7.

[0042] The calibration end 7 includes a fixed base 71 connected to the collar 3. The fixed base 71 has an insertion slot for inserting the calibration rod 72, and the support base 8 has a groove 81 that cooperates with the calibration rod 72.

[0043] The setting of calibration end 7 and support base 8 makes it easy for staff to observe whether the centers of the two collars 3 are aligned. When the centers of the two collars 3 are aligned, the adjustment work of the pipe end contact can be reduced.

[0044] Specifically, when the two calibration rods 72 move synchronously into the tank 81, the two collars 3 are aligned. With the two collars 3 aligned, the ends of the two pipes will also be aligned synchronously, or there will be a certain height difference, which reduces the adjustment work of the inner diameter adjustment component 4 to a certain extent. The setting of the calibration rods 72 and the tank 81 can provide certain alignment reference conditions for the work, which reduces the time used for pipe alignment to a certain extent.

[0045] In this embodiment, after the ends of the two pipes are connected, the operator can disassemble the calibration rod 72 by pulling it upwards, thereby ensuring the smoothness of the pipe welding.

[0046] Preferred, Reference Figures 4-6 Two auxiliary support members 9 are provided at the bottom of the strength plate 43 located on the inner side of the collar 3;

[0047] The auxiliary support member 9 includes a slot 91 opened at the bottom of the strength plate 43, a block 92 that cooperates with the slot 91, and an auxiliary support rod 93 that is set at the bottom of the block 92. The inner side of the collar 3 and the two sides of the screw are provided with inner holes 94 that cooperate with the ends of the auxiliary support rod 93.

[0048] The auxiliary support rod 93 includes a fixed rod 931 connected to the locking block 92, an adjustment groove 932 opened on the fixed rod 931, and a spring body 933 disposed in the adjustment groove 932. One end of the spring body 933 is connected to a movable rod 934. A plurality of first fixing holes 935 are provided through the movable rod 934. A second fixing hole 936 that cooperates with the first fixing holes 935 is opened on the fixed rod 931. A locking rod 937 is provided through the first fixing hole 935 and the second fixing hole 936.

[0049] The auxiliary support member 9 rods can distribute the force exerted by the pipe on the strength plate 43 below the inner side of the spring, and reduce the gravity on the strength plate 43 and the adjusting screw 42, thereby increasing the service life of the strength plate 43 and the adjusting screw 42 to a certain extent.

[0050] Specifically, after the collar 3 is connected to the pipe, the worker removes the auxiliary support 9, then presses the movable rod 934 and retracts the spring body 933. Next, the worker inserts the locking block 92 into the slot 91 and pushes the fixed rod 931 inward, causing the end of the movable rod 934 to move into the inner hole 94. Finally, the worker inserts the locking rod 937 into the first fixed hole 935 and the second fixed hole 936, and fixes the connection between the fixed rod 931 and the movable rod 934. The fixed rod 931 and the connecting rod will serve as auxiliary support for the strength plate 43 after fixing.

[0051] In this embodiment, the adjustment groove 932 provides a basis for the telescopic movement of the movable rod 934.

[0052] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
