[0026] Reference below Figures 1 to 3 To describe the lifting tool according to the embodiment of the utility model.

[0027] According to the lifting tool of the embodiment of the utility model, it includes a supporting beam 100, a fixing device and a supporting device. One end of the supporting beam 100 is used for lifting the pipe; the fixing device is arranged at the other end of the supporting beam 100, and the fixing device is used for sleeve-mounting the pipe; one end of the supporting device is connected to the middle part of the supporting beam 100, and the other end is used for abutting the pipe.

[0028] For example Figure 1 and Figure 2 As shown, the lifting tool is provided with a supporting beam 100, and the fixing device and the supporting device are connected to the bottom of the supporting beam 100. One end of the supporting beam 100 is used for lifting the pipe, and the other end is provided with a fixing device for sleeve installation of the pipe. The supporting device is located in the middle of the supporting beam 100 to form a lever, for example Figure 2 As shown in the given embodiment, the pipe A610 is already installed and fixed, and the fixed pipe A610 is sleeved by the fixing device, and the bottom of the supporting device is in contact with the upper end surface of the pipe A610, so as to support the supporting crossbeam 100. At this time, the other end of the supporting crossbeam 100 lifts the pipe B620, and through the lever effect, the pipe B620 can be easily pulled to complete the docking of the pipe B620 with the already fixed pipe A610, so that the center lines of the pipe openings of the two pipes are aligned, and the two pipes can be welded or clamps can be installed to connect the two pipes to each other.

[0029] After the two pipes are connected, the fixture can be moved, and the fixture and the supporting device can be moved to the pipe B620, and then the next pipe can be installed.

[0030] The lifting tool according to the embodiment of the utility model has a simple structure, low cost, easy operation, high efficiency and flexibility, improves the convenience of field pipeline installation operations, reduces the use of large lifting tools such as cranes, reduces the danger of lifting operations, can effectively reduce work costs and manpower, and plays a role in safe and fast installation operations. With the help of this tool, the lifting and jointing of larger pipelines can be completed at a relatively low cost, greatly reducing the maintenance cost and maintenance time.

[0031] In some specific embodiments of the present invention, the fixing device includes a first connecting rod 210 and a clamping device. One end of the first connecting rod 210 is connected to the supporting beam 100, and the other end is connected to the clamping device. The clamping device is used to sleeve the pipeline.

[0032] For example Figure 1 and Figure 2As shown, the fixing device includes a first connecting rod 210 and a clamping device, one end of the first connecting rod 210 is connected to the supporting beam 100, and the other end is connected to the clamping device, and the clamping device is used to sleeve the pipe A610. Through the arrangement of the first connecting rod 210, there is a certain distance between the clamping device and the supporting beam 100, which facilitates the supporting beam 100 to play the role of a lever.

[0033] The clamping device is used to cover the pipe. The shape of the clamping device is consistent with the shape of the pipe. According to the size of the pipe, you can choose clamping devices of different sizes to cover the pipe and cover the pipe. Because the pipe is generally cylindrical, the clamping device is also circular, so that the pipe can be framed in it.

[0034] The clamping device can be designed in a circular shape and inserted into one end of the pipe A610, or it can be designed as two semicircular connecting pieces and connected through the two semicircular connecting pieces.

[0035] In some specific embodiments of the present invention, the first connecting rod 210 is rotatably connected to the supporting beam 100 .

[0036] For example Figure 1 As shown, the first connecting rod 210 and the supporting beam 100 are rotatably connected. The rotatable connection makes the use of the lifting tool more convenient. After the clamping device is clamped around the installed and fixed pipe A610, the supporting beam 100 can be easily rotated, so that the supporting device is placed on the pipe A610 to form a stable lever structure. The pipe B620 is hoisted with the other end of the supporting beam 100 so that the center lines of the two pipe openings are aligned. At this time, the two pipes can be welded or clamps can be installed to connect the two pipes to each other.

[0037] In some specific embodiments of the present invention, the clamping device includes a first connecting member 220 and a second connecting member 230. Both ends of the first connecting member 220 and the second connecting member 230 are connected to each other for sleeves of the pipes.

[0038] For example Figure 1 and Figure 2 As shown, the clamping device includes a first connecting member 220 and a second connecting member 230, and both ends of the first connecting member 220 and the second connecting member 230 are connected to each other, so that the pipe A610 is sleeved therein.

[0039] In some specific embodiments of the present invention, the first connecting member 220 includes a first curved plate 221, connecting plates 222 are provided at both ends of the first curved plate 221, and bolt holes are opened on the connecting plates 222; the second connecting member 230 includes a second curved plate 231, screws 232 are provided at both ends of the second curved plate 231; the first connecting member 220 and the second connecting member 230 are connected through the screws 232 and the bolt holes.

[0040] For example Figure 1 and Figure 2 As shown, the first connecting member 220 includes a first curved plate 221, and connecting plates 222 are provided at both ends of the first curved plate 221, and bolt holes are provided on the connecting plates 222. The second connecting member 230 includes a second curved plate 231, and screw rods 232 are provided at both ends of the second curved plate 231. When installing, the first curved plate 221 is first placed on the upper end surface of the pipe A610, so that the inner concave surface of the first curved plate 221 abuts against the pipe A610. At this time, the screw rods 232 at both ends of the second curved plate 231 are aligned with the bolt holes on the connecting plate 222 and inserted into the connecting plate 222, so that the inner concave surface of the second curved plate 231 abuts against the lower end surface of the pipe A610. At this time, the screw rods 232 are fixed by nuts 233, so that the first connecting member 220 and the second connecting member 230 can stably hold the pipe A610.

[0041] Furthermore, the bending radius of the first arc plate 221 and the second arc plate 231 is the same as the end surface radius of the pipe, so that they can be well fitted on the surface of the pipe.

[0042] Furthermore, the first arc plate 221 and the second arc plate 231 are both semicircular, so that the first arc plate 221 and the second arc plate 231 can form a complete circle to frame the pipe A610, making the connection between the clamping device and the pipe A610 more stable.

[0043] In some specific embodiments of the present invention, the supporting device includes a second connecting rod 310 and a supporting plate 320. One end of the second connecting rod 310 is connected to the supporting beam 100, and the other end is connected to the supporting plate 320. The supporting plate 320 is used to abut against the pipeline.

[0044] For example Figure 1 and Figure 2 As shown, the support device includes a second connecting rod 310 and a support plate 320. The second connecting rod 310 connects the support beam 100 and the support plate 320, so that when the support plate 320 abuts against the pipe A610, the second connecting rod 310 can act as a fulcrum of the lever, which is beneficial for lifting the pipe B620 at the other end of the support beam 100, so that the center lines of the pipe openings of the two pipes are aligned. At this time, the two pipes can be welded or clamps can be installed to connect the two pipes to each other.

[0045] In some specific embodiments of the present invention, the second connecting rod 310 is rotatably connected to the supporting beam 100 .

[0046] For example Figure 1 As shown, the top end of the second connecting rod 310 is rotatably connected to the supporting beam 100, so that the supporting plate 320 can be easily rotated through the second connecting rod 310, so as to be placed above the pipe A610 and abut against the upper surface of the pipe A610.

[0047] In some specific embodiments of the present invention, the support plate 320 is an arc-shaped plate structure, and the inner concave surface of the support plate 320 is used to abut against the pipeline.

[0048] For example Figure 1 As shown, the support plate 320 is an arc-shaped structure, and the inner concave surface of the support plate 320 abuts against the pipe A610, so that the support plate 320 can stably abut against the pipe A610, so that the second connecting rod 310 and the support plate 320 can act as a fulcrum, which is convenient for the lifting tool to achieve a lever effect through the second connecting rod 310 and the support plate 320, and it is convenient to lift the pipe B620 and connect it with the pipe A610.

[0049] In some specific embodiments of the utility model, the supporting device includes a second connecting rod 310 and a clamping assembly, one end of the second connecting rod 310 is connected to the supporting beam 100, and the other end is used to abut the pipeline; a driving motor 710 and an adjusting screw 720 are arranged in the second connecting rod 310, and the clamping assembly includes two movable gears 730 and a clamping claw 740 symmetrically arranged along the axial direction of the adjusting screw 720, the gear teeth of the two movable gears 730 are meshed with the threads of the adjusting screw 720, and the clamping claw 740 is connected to the movable gear 730, and the driving motor 710 drives the adjusting screw 720 to rotate so that the movable gear 730 rotates, thereby driving the clamping claw 740 to rotate synchronously to grasp the pipeline.

[0050] For example Figure 3As shown, the top end of the second connecting rod 310 is connected to the supporting beam 100, and the other end is in contact with the pipe A610 and supported on the pipe A610. The driving motor 710, the adjusting screw rod 720 and the movable gear 730 are built in the second connecting rod 310, and the clamping claw 740 is fixedly connected with the movable gear 730, extending from the second connecting rod 310 and clamped on the outer wall of the pipe A610. When working, the second connecting rod 310 supports the supporting beam 100, and the driving motor 710 rotates at the same time, thereby driving the adjusting screw rod 720 to rotate, and the thread of the adjusting screw rod 720 is meshed with the gear teeth of the movable gear 730, so that the rotation of the adjusting screw rod 720 can drive the movable gear 730 to rotate. The clamping claw 740 is fixedly connected with the movable gear 730, and the rotation of the movable gear 730 drives the clamping claw 740 to rotate, so that the pipe A can be grasped, so that the second connecting rod 310 can stably support the supporting beam 100 without shaking.

[0051] Furthermore, the portion where the clamping claw 740 contacts the pipe is provided with an anti-slip pad, which enables the clamping claw 740 to grip the pipe more firmly, making the supporting device more stable and less prone to shaking.
