Description

Technical Field

[0001] The invention relates to the technical field of cutting devices, in particular to a BWFRP electric power pipe cutting device. Background Art

[0002] BWFRP power pipe is a kind of pipe specially used in power engineering. When BWFRP power pipe is officially put into use, it is often precisely cut according to the required length. At present, the main machine used is electric pipe cutting machine. This machine is specially designed for cutting hard pipes and is equipped with a saw blade suitable for cutting glass fiber reinforced plastic (FRP), which can ensure that the cutting surface is flat and smooth.

[0003] The patent with the announcement number CN216914035 discloses an electric pipe cutting device, including: a body, including a support frame, the surface of the support frame is movably connected with a rotating column, the surface of the support frame is provided with a cutting assembly, the cutting assembly and the support frame are rotatably connected, and the cutting assembly is composed of a cutting blade and a motor; a support mechanism, including a connecting plate, the connecting plate is slidably connected to the inner side of the support frame, and the end of the connecting plate away from the support frame is connected to an adjusting rod by a thread. The cutting device realizes the change of the distance between the support plate and the support frame through the rotation connection of the support rod and the support frame, thereby achieving the effect of supporting electric pipes with a longer length, and the rotating wheel and the fixed frame slide on the support plate, which can change the change of the support distance between the rotating wheels, so as to achieve the effect of supporting electric pipes of different sizes, and under the action of the screw and the screw sleeve, the position adjustment and fixation of the fixed frame on the support plate are achieved.

[0004] However, the above cutting device still has the following problems in actual use:

[0005] When placing the pipe on the cutting device, in order to prevent the pipe from "warping up" after being cut, a support platform needs to be placed or built on one side of the cutting device.

[0006] If the BWFRP pipe to be cut is very long, the support table needs to be placed far away (at least at the center point of the pipe after cutting to avoid the pipe from tilting and "warping"). If the pipe needs to be cut into many short pipes at this time, the pipe needs to be pulled and adjusted after cutting for secondary cutting. When the length of the cut pipe is less than the distance between the support table and the cutting device, the position of the support table needs to be adjusted. During the adjustment process, it is also necessary to confirm whether the height and angle of the support table are the same as those of the cutting device. The overall operation is very time-consuming, which leads to reduced cutting efficiency. Summary of the invention

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] See also Figure 1-Figure 13 , a bwfrp electric pipe cutting device comprises a support seat 1, a bracket 2 installed on the support seat 1 and a cutting wheel 3 installed on the bracket 2, one side of the upper surface of the support seat 1 is fixedly connected with an L-shaped frame 4, the upper surface of the support seat 1 and the bottom surface of the upper end of the L-shaped frame 4 are connected with two support assemblies, the other ends of the four support assemblies are connected with support plates 15, the other ends of the four support plates 15 are connected with rolling assemblies, the four rolling assemblies are symmetrical to each other, the sides of the four support plates 15 away from each other are connected with pushing assemblies, the other ends of the four pushing assemblies are respectively connected to the support seat 1 and the L-shaped frame 4, an auxiliary rotating assembly is connected between the two support plates 15 located on the support seat 1 and the L-shaped frame 4, the two auxiliary rotating assemblies are aligned up and down, the bottom surface of the support seat 1 is connected with an air source mechanism, the output end of the air source mechanism is connected with a three-way pipe 20, the other two ends of the three-way pipe 20 are respectively connected with an expansion gas supply assembly and a pushing gas supply assembly, the other two ends of the expansion gas supply assembly are respectively connected to the two auxiliary rotating assemblies, and the other four ends of the pushing gas supply assembly are respectively connected to the four pushing assemblies.

[0039] The bwfrp power pipe cutting device in the present invention is similar in structure to the existing bwfrp power pipe cutting device, such as the power pipe cutting device disclosed in the patent with the announcement number CN216914035. Figures 1 to 13 As shown, the BWFRP electric pipe cutting device of the present invention can be used in the following steps:

[0040] 1. First, place the cutting device consisting of the support seat 1, the bracket 2 and the cutting wheel 3 in a suitable position to carry out the subsequent normal cutting of the bwfrp power pipe.

[0041] 2. Then, the gas source mechanism is started through an external controller (or the controller provided by the cutting device), and the gas supply assembly is started at the same time as the gas source mechanism is started.

[0042] 3. As the push gas delivery component is opened, the high-pressure airflow inside the gas source mechanism will enter the four push components through the push gas delivery component.

[0043] 4. The high-pressure airflow entering the push assembly will control the four support plates 15 to rotate around the four support assemblies, thereby enabling them to open outward or merge inward at the same time.

[0044] 5. As the positions of the support plates 15 change, the positions of the four rolling components at the other ends of the four support plates 15 will also change simultaneously, and in the process of change, the area between the four rolling components will become larger or smaller.

[0045] 6. When the distance between two adjacent rolling assemblies is greater than the diameter of the bwfrp power pipe to be cut, the air source mechanism is closed through the controller.

[0046] 7. At this time, the BWFRP power pipe is placed from between the two outward rolling assemblies into the area between the four rolling assemblies by manual or external lifting equipment.

[0047] 8. After placing the bwfrp power tube between the four rolling components, continue to keep the bwfrp power tube stationary and start the air source mechanism again.

[0048] 9. At this time, the air source mechanism controls the four rolling components to retract inward, so that the internal space area between the four rolling components becomes smaller, until the four rolling components press against the bwfrp power pipe from the four sides outside.

[0049] 10. At the moment when the four rolling components press the BWFRP power pipe tightly, the rolling components transmit electrical signals to the processor and close the air source mechanism through the controller.

[0050] 11. At this time, press the cutting wheel 3 normally and turn on the motor behind the cutting wheel 3 to complete the cutting operation of the bwfrp power pipe normally.

[0051] 12. At the moment when the bwfrp power tube is cut by the cutting wheel 3, because the four rolling components squeeze the bwfrp power tube from all sides, and the bwfrp power tube is still a hard tube, the bwfrp power tube will not warp at this time, thus saving the time of building a support platform.

[0052] 13. When it is necessary to cut the remaining bwfrp power pipes again, open the gas source mechanism through the controller again.

[0053] 14. When the gas source mechanism is started again, high-pressure gas will be delivered to the interior of the expansion gas delivery component. At this time, the expansion gas delivery component will deliver this part of high-pressure gas to the four auxiliary rotating components respectively.

[0054] 15. (This step can be understood in conjunction with step 4) When the position of the support plate 15 changes, the two auxiliary rotating components located between the two groups of support plates 15 will also change position accordingly.

[0055] 16. When the opening (angle) between the support plates 15 becomes larger, the opening between the auxiliary rotating components will also become larger, so that the height of the auxiliary rotating components can be closer to the position between the support seat 1 or the L-shaped frame 4; conversely, when the opening between the support plates 15 becomes smaller, the height of the auxiliary rotating components and the position between the support seat 1 or the L-shaped frame 4 become farther, so no matter whether the bwfrp power pipe to be cut is a thick pipe or a thin pipe, the distance between the auxiliary rotating assembly and the bwfrp power pipe will not be too different.

[0056] 17. (Here is a supplementary explanation of step 14) As the high-pressure gas enters the four auxiliary rotating components, the four auxiliary rotating components will expand and become larger, and then the bwfrp power pipe to be cut can be squeezed and clamped from the upper and lower sides.

[0057] 18. After the bwfrp power tube is clamped by the four auxiliary rotating components, part of the gas is withdrawn from the four pushing components through the controller, so that the friction between the four pushing components and the bwfrp power tube becomes smaller. Of course, at this time, the four auxiliary rotating components still maintain the clamping of the bwfrp power tube.

[0058] 19. Then, push the bwfrp power tube toward the cutting wheel 3 manually or through external equipment to move it again to the distance required for cutting. Then, control the pushing assembly through the air source mechanism to clamp the bwfrp power tube again. After the bwfrp power tube is clamped, draw back gas from the inside of the auxiliary rotating assembly through the air source mechanism.

[0059] 20. Then continue to cut the bwfrp power tube by the cutting wheel 3. When three cuts are required, repeat the above steps 12 to 19. If no subsequent cutting is required, just control the four pushing components through the air source mechanism to unfold the four support plates 15, and then take the bwfrp power tube out from the two outward rolling components.

[0060] Special mention should be made here:

[0061] 1. The cutting device composed of the support base 1, the bracket 2 and the cutting wheel 3 is a prior art, for example, the model is: TY-260 electric hydraulic pipe cutting machine, so its working principle, connection relationship, etc. are not described in detail here.

[0062] 2. External controller or cutting device with its own controller This is also the prior art, so it will not be described in detail here.

[0063] As a preferred solution of the present invention, the support assembly includes a support shaft 41 and two support blocks 17, the two ends of the support shaft 41 are respectively fixedly connected to the two support blocks 17, the lower ends of the two support blocks 17 located on the support seat 1 are fixedly connected to the upper surface of the support seat 1, and the lower ends of the two support blocks 17 located on the L-shaped frame 4 are fixedly connected to the surface of the L-shaped frame 4, and the support plate 15 is sleeved on one end away from the rolling assembly and rotatably connected to the outer wall of the support shaft 41.

[0064] More specifically, by providing the support assembly, support and rotation hinge points can be provided for the support plate 15, the rolling assembly, etc.

[0065] The specific method is as follows: when the pushing assembly pushes the support plate 15 to rotate, the support plate 15 will rotate between the two support blocks 17 with the support shaft 41 as the axis.

[0066] As a preferred embodiment of the present invention, the rolling assembly includes a support rod 5, a roller 6 and a contact sensor 8. The outer wall of one end of the support rod 5 is rotatably connected to the inner wall of the support plate 15 away from the end of the support shaft 41. The roller 6 is sleeved and fixedly connected to the outer wall of the other end of the support rod 5. A sleeve 45 is opened in the middle of the outer wall of the roller 6. The contact sensor 8 is sleeved and fixedly connected to the inner wall of the sleeve 45. The two support rods 5 located below are fixedly connected to support rollers 10, and the two support rollers 10 are located below the cutting wheel 3.

[0067] More specifically, by setting up a rolling assembly, support can be provided for the bwfrp power tube to be cut, and when the cutting wheel 3 cuts the bwfrp power tube, the rotation of the bwfrp power tube will not be affected.

[0068] The specific method is: when cutting, the bwfrp power pipe to be cut is placed on the two rollers 6 and the support roller 10 below. At this time, the rollers 6 and the support rollers 10 are kept stably supported because of the support rods 5.

[0069] Then, the two rollers 6 located on the L-shaped frame 4 are controlled by the air source mechanism to press on the upper side of the bwfrp power tube. When the four contact sensors 8 detect at the same time that the set pressure value is reached, the electrical signal is immediately transmitted to the processor wirelessly, and the air source mechanism is controlled by the controller to stop supplying air. At this time, the bwfrp power tube will be tightly confined in the middle due to the action of the four rollers 6, and will not warp. Moreover, because the rollers 6 and the support rollers 10 are round, the normal rotation of the bwfrp power tube and the cutting wheel 3 during contact cutting will not be affected.

[0070] As a preferred solution of the present invention, the pushing component includes a pushing air head 32, a sealing component, two auxiliary plates 18, two pushing connecting heads 31 and two auxiliary shafts 33, one end of the two auxiliary plates 18 is fixedly connected to the support plate 15 and the support seat 1 respectively, the other ends of the two auxiliary plates 18 are respectively sleeved and rotatably connected to one end of the two auxiliary shafts 33, the other ends of the two auxiliary shafts 33 are respectively fixedly connected to the outer walls of the two pushing connecting heads 31, the two ends of the sealing component are respectively connected to the adjacent ends of the two pushing connecting heads 31, one of the pushing connecting heads 31 is provided with a pushing air hole 46, the outer wall of the pushing air head 32 is fixedly connected to the outer wall of this pushing connecting head 31, and the pushing air head 32, the pushing air hole 46, the pushing air transmission component and the sealing component are internally connected.

[0071] More specifically, by setting a pushing component, a more reasonable distance adjustment can be made according to the different thicknesses and sizes of bwfrp power tubes.

[0072] The specific method is: when the position of the roller 6 needs to be adjusted, as the high-pressure gas of the gas source mechanism is delivered to the pushing gas head 32, this part of the gas will immediately enter the interior of the sealing component, and then the other end of the sealing component will extend outward, so that the other pushing connector 31 can be pushed and moved, and the two pushing connectors 31 will both rotate inside the two auxiliary plates 18 through the two auxiliary shafts 33, thereby achieving the purpose of pushing the support plate 15 to move.

[0073] As a preferred solution of the present invention, the sealing assembly includes an outer tube 9, an inner rod 30 and a piston 42. One end of the outer tube 9 is fixedly connected to a push connector 31 having a push air hole 46. A push cavity 43 is provided inside the outer tube 9. The outer wall of the piston 42 is slidably connected to the inner wall of the push cavity 43. One end of the piston 42 is fixedly connected to one end of the inner rod 30. The other end of the inner rod 30 passes through the push cavity 43 to the outside of the outer tube 9 and is fixedly connected to another push connector 31. The push air hole 46 is connected to the inside of the push cavity 43.

[0074] More specifically, by providing a sealing component, not only can the gas delivered by the gas source mechanism be limited from leaking, but the angle of the support plate 15 can also be adjusted by using this gas.

[0075] The specific method is: when the high-pressure gas enters the pushing gas head 32, it will enter the pushing cavity 43 of the outer tube 9 along the pushing gas hole 46, and then the piston 42 originally located in the pushing cavity 43 can be pushed toward the other end. During the movement of the piston 42, the inner rod 30 can be pushed to move together, so that the pushing connector 31 and the support plate 15 at the other end of the inner rod 30 can be pushed to change their position (angle).

[0076] As a preferred solution of the present invention, the air source mechanism includes an air pump 7 and a mounting seat 19, the outer wall of the mounting seat 19 is fixedly connected to the bottom surface of the support seat 1, the other side of the mounting seat 19 is fixedly connected to the outer wall of the air pump 7, and the output end of the air pump 7 is fixedly connected to one end of the three-way pipe 20.

[0077] More specifically, by providing an air source mechanism, a power source can be provided to the inside of the pushing component and the auxiliary rotating component.

[0078] The specific method is: firstly, the air pump 7 is stably mounted on the support base 1 through the mounting base 19, and then the air pump 7 can be used to transport gas to the inside of the three-way pipe 20, thereby achieving the above-mentioned step effects.

[0079] As a preferred embodiment of the present invention, the expansion gas transmission component includes an expansion gas pipe 11, a No. 1 solenoid valve 22, two expansion multi-way pipes 23, four expansion branch pipes 25 and four extension pipes 44, one end of the No. 1 solenoid valve 22 is fixedly connected to one end of the three-way pipe 20, the other end of the No. 1 solenoid valve 22 is fixedly connected to one end of the first expansion multi-way pipe 23, the other end of the first expansion multi-way pipe 23 is fixedly connected to one end of the expansion gas pipe 11, the other end of the expansion gas pipe 11 is fixedly connected to one end of the second expansion multi-way pipe 23, one end of the four expansion branch pipes 25 is respectively fixedly connected to the remaining four ends of the two expansion multi-way pipes 23, the inner walls of the other ends of the four expansion branch pipes 25 are respectively slidably connected to the outer walls of the four extension pipes 44, the other ends of the four extension pipes 44 are respectively connected to four auxiliary rotating components, and the three-way pipe 20, the expansion gas pipe 11, the No. 1 solenoid valve 22, the expansion multi-way pipe 23, the expansion branch pipe 25 and the extension pipe 44 are internally connected.

[0080] More specifically, by setting up an expansion gas delivery component, gas can be delivered to the interior of the auxiliary rotating component to achieve the purpose of assisting the movement of the BWFRP power pipe.

[0081] The specific method is: when it is necessary to control the movement of the bwfrp power pipe, first open the No. 1 solenoid valve 22, and then the output end of the air pump 7 starts to deliver high-pressure gas through the three-way pipe 20. After that, this part of the high-pressure gas will pass through the No. 1 solenoid valve 22, the first expansion multi-way pipe 23, the expansion air pipe 11, the second expansion multi-way pipe 23, the expansion branch pipe 25 and the extension pipe 44, and then enter the four auxiliary rotating components, so that the four auxiliary rotating components can be expanded to achieve the purpose of supporting the bwfrp power pipe, which can facilitate workers to pull the bwfrp power pipe from one side.

[0082] It should be noted that the expansion air pipe 11, the expansion multi-way pipe 23, the expansion branch pipe 25 and the extension pipe 44 are all hard pipes with support properties, which are used to support the auxiliary rotating assembly and limit the rotation of the auxiliary rotating assembly itself.

[0083] As a preferred solution of the present invention, the auxiliary rotating assembly includes a support shaft 27, two connecting plates 16, two connecting shafts 28, two anti-slip assemblies and two inflation air bags 12. A turning opening 29 is opened on one side of the lower end of the two support plates 15. One end of the two connecting shafts 28 is fixedly connected to the inner walls of the two turning openings 29, respectively. One end of the two connecting plates 16 is respectively sleeved and rotatably connected to the outer walls of the two connecting shafts 28. The other ends of the two connecting plates 16 are simultaneously sleeved and rotatably connected to the outer wall of the support shaft 27. The two ends of the support shaft 27 are respectively connected to the two anti-slip assemblies. The two inflation air bags 12 are respectively sleeved on the outside of the two anti-slip assemblies. The end of the extension tube 44 away from the inflation branch pipe 25 is connected to the anti-slip assembly and is internally connected.

[0084] More specifically, by setting up an auxiliary rotating component, when it is necessary to control the movement of the bwfrp power tube, rolling support can be provided on the upper and lower sides of the bwfrp power tube to facilitate pulling the bwfrp power tube.

[0085] The specific method is: in the normal cutting state, the bwfrp power tube is placed on four rollers 6, and the expansion airbag 12 is not in contact with the bwfrp power tube and does not provide friction to it; when it is necessary to control the movement of the bwfrp power tube, the high-pressure gas passes through the extension tube 44 through the anti-detachment component and enters the expansion airbag 12, thereby increasing the volume of the expansion airbag 12, thereby supporting the bwfrp power tube and clamping it on the upper and lower sides.

[0086] It should be noted here that the expansion of the inflatable airbag 12 has a certain degree of expansion. When the internal gas delivery reaches a sufficient amount, the inflatable airbag 12 can no longer continue to expand, and pressure sensors are provided inside the four inflatable airbags 12 (this is the existing technology, so it is not described in detail). When the internal pressure of the four inflatable airbags 12 reaches the set value, the air source mechanism will be immediately controlled to close, or the No. 1 solenoid valve 22 will be controlled to close.

[0087] As a preferred embodiment of the present invention, the anti-slip assembly includes a limit column 34, an expansion connector 36, two support columns 14 and two anti-slip plates 35. The limit column 34 is sleeved and fixedly connected to the end of the support shaft 27. The two ends of the limit column 34 are respectively fixedly connected to the two anti-slip plates 35. One end of the expansion connector 36 is fixedly connected to the side wall of the limit column 34. An anti-slip cavity 40 is provided on the adjacent side of the two support columns 14. An expansion air inlet hole 39 is provided at the bottom of the two anti-slip cavities 40. The two expansion air bags 12 are respectively sleeved and fixedly connected to the outer walls of the two support columns 14. The interiors of the two expansion air bags 12 are each provided with an expansion air cavity 38. The interiors of the limit column 34 are provided with an expansion air supply hole 37. The outer wall of the extension tube 44 away from one end of the expansion branch pipe 25 is fixedly connected to the inner wall of the expansion connector 36. The extension tube 44, the expansion connector 36, the expansion air supply hole 37, the expansion air inlet hole 39 and the expansion air cavity 38 are internally connected.

[0088] More specifically, by setting up an anti-slip assembly, firstly, support can be provided to the inflatable airbag 12 ; secondly, the transmission bwfrp power pipe will not be affected; finally, gas can be transported to the inside of the inflatable airbag 12 .

[0089] The specific method is as follows: when the high-pressure gas is transmitted from the extension tube 44, it will enter the expansion gas supply hole 37 through the expansion connector 36, and then enter the expansion gas cavity 38 through the expansion gas supply hole 37 and the expansion gas inlet hole 39, thereby inflating the expansion airbag 12.

[0090] As a preferred solution of the present invention, the pushing gas delivery component includes two pushing air pipes 13, three pushing multi-way pipes 21, four No. 2 solenoid valves 24 and four pushing branch pipes 26, one end of the first pushing multi-way pipe 21 is fixedly connected to one end of the three-way pipe 20, the other end of the first pushing multi-way pipe 21 is fixedly connected to one end of the first pushing air pipe 13, the other end of the first pushing air pipe 13 is fixedly connected to one end of the second pushing multi-way pipe 21, the other end of the second pushing multi-way pipe 21 is fixedly connected to one end of the second pushing air pipe 13, the other end of the second pushing air pipe 13 is fixedly connected to one end of the third pushing multi-way pipe 21, the remaining four ends of the three pushing multi-way pipes 21 are respectively fixedly connected to one end of the four pushing branch pipes 26, the other ends of the four pushing branch pipes 26 are respectively fixedly connected to four pushing air heads 32, the four No. 2 solenoid valves 24 are respectively arranged on the four pushing branch pipes 26, and the three-way pipe 20, the pushing air head 32, the pushing air pipe 13, the pushing multi-way pipe 21, the No. 2 solenoid valves 24 and the pushing branch pipes 26 are internally connected.

[0091] More specifically, by providing a propulsion gas delivery component, power can be provided to the propulsion component.

[0092] The specific method is: when it is necessary to control the angle change of the support plate 15, the air pump 7 is started, and the output end supplies air to the outside, entering the two pushing air pipes 13, the three pushing multi-way pipes 21, the four No. 2 solenoid valves 24 and the four pushing branch pipes 26 through the three-way pipe 20, and then entering the pushing air head 32 from the four pushing branch pipes 26, so as to realize the pushing of the four pistons 42 to control the angle change of the four support plates 15.

[0093] It should be specially noted here that in order to make the gas entering the four push chambers 43 the same and realize the synchronous movement of the four pistons 42 and the inner rod 30, the four No. 2 solenoid valves 24 can be controlled separately to control different intake speeds or intake volumes, etc.

[0094] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
