Description

Technical Field

[0001] The present invention belongs to the technical field of pipeline cutting, and in particular is an MPP power pipe cutting device for power construction and a use method thereof. Background Art

[0002] MPP power pipe, also known as MPP power cable protection pipe, is a pipe designed and manufactured for power cables. It serves as a protective layer for the cable to ensure the safety and stability of the cable during laying and use.

[0003] Then the existing MPP power pipe cutting device used in power construction still has disadvantages in actual use: in order to save the use cost, some processing factories still adopt manual cutting method. After the MPP power pipe is placed stably, the two ends of the MPP power pipe are auxiliary limited. The operator holds the cutting tool in one hand and holds the MPP power pipe with the other hand, and cuts slowly from top to bottom. During the cutting process, the operator needs to limit the MPP power pipe at all times to prevent it from shaking so as to ensure the cutting accuracy and smoothness. It is time-consuming and labor-intensive during long-term operation, and has high requirements on the operator's concentration, so it needs to be improved. Summary of the invention

[0004] In order to solve the problem mentioned in the above background technology that some processing factories adopt manual cutting method in order to save usage costs, after the MPP power pipe is placed stably, the two ends of the MPP power pipe are auxiliary limited, and the operator holds the cutting tool in one hand and holds the MPP power pipe with the other hand, and slowly cuts from top to bottom. During the cutting process, the operator is required to limit the MPP power pipe at all times to prevent it from shaking so as to ensure the cutting accuracy and cutting smoothness, and the problem of time-consuming and labor-intensive operations during long-term operations. The present invention provides an MPP power pipe cutting device for power construction and a method for using the same.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an MPP power pipe cutting device for power construction, comprising a base and an MPP power pipe body, and further comprising:

[0006] A limit module, wherein the limit module is installed on the top of the base;

[0007] A cutting module, wherein the cutting module is fixedly connected to the top surface of the base and is closely connected to the inner wall of the limiting module;

[0008] The movable modules are arranged on both sides of the top of the base and are abuttingly connected with the pressing components;

[0009] The limiting module comprises an arc plate, the bottom of which is fixedly connected to the top of the base, a protective pad is fixedly installed inside the arc plate, and a movable groove for enabling the cutting module to move is opened in the middle of the arc plate;

[0010] The movable module comprises a fixed ring and a rotating shaft fixed to the base, a gear ring is slidably engaged on one side of the fixed ring, and the arc plate is connected to the base bearing through the rotating shaft;

[0011] The pressing assembly comprises a positioning block, both ends of which extend into the interior of the fixing ring, and both sides of the positioning block are fixedly mounted with connecting columns which are in contact with the gear ring.

[0012] Preferably, the arc plates, protective pads and movable grooves are provided in two groups, and are symmetrical with the longitudinal center axis plane of the base. The contact ends of the two groups of arc plates are snap-connected. After the two groups of arc plates are docked, a shape similar to a "circular tube" will be formed to provide cutting protection for the MPP power pipes to be cut later, thereby preventing the waste chips generated during the cutting process from splashing and scattering, which is inconvenient for subsequent collection.

[0013] Preferably, a discharge trough for allowing impurities produced by cutting to fall is provided at the lower ends of the inner cavities of the two arc plates, and the bottom of the arc plates is connected to the movable module.

[0014] Preferably, the movable module comprises a servo motor mounted on a base, the output end of the servo motor is fixedly connected to the rotating shaft, the outer walls of both ends of the rotating shaft are sleeved with spur gears, and the outer walls of the spur gears are meshed with a gear ring;

[0015] The rotating shaft is fixedly connected to the arc plate on one side, and the servo motor drives the rotating shaft to rotate through its output end. The rotating shaft will drive a single arc plate to flip over. When the arc plate connected to the rotating shaft flips downward, the two arc plates will be in an open state, and the MPP power tube body can be placed inside the two arc plates. Conversely, when the arc plate connected to the rotating shaft flips upward, the two rotating shafts are connected, and the outside of the MPP power tube body can be relatively closed.

[0016] Preferably, an arc-shaped protrusion is provided inside the gear ring, and the outer wall of the arc-shaped protrusion abuts against the connecting column. When the gear ring rotates, the arc-shaped protrusion on its inner wall will be driven to rotate synchronously. When the arc-shaped protrusion contacts the connecting column, it will gradually press down the connecting column, so that the connecting column drives the positioning block downward.

[0017] Preferably, a first spring is provided on the top surface of one end of the positioning block that passes through the interior of the fixing ring, and the top of the first spring is fixedly connected to the top surface of the inner cavity of the fixing ring. The positioning block is elastically connected to the fixing ring through the first spring. When the connecting column is contacted by the arc-shaped protrusion of the inner wall of the gear ring and drives the positioning block downward, the first spring is in a stretched state. On the contrary, when the arc-shaped protrusion of the inner wall of the gear ring does not contact the connecting column, the stretched first spring will release the elastic force to drive the positioning block to reset upward.

[0018] Preferably, the cutting module comprises a first bracket and a second bracket, both of which are fixedly connected to the base, a limit block and a motor transmission module are respectively installed on the top of the first bracket, and a cutting knife is hinged on the top of the second bracket.

[0019] Preferably, a groove for enabling the cutting knife to flip and move is provided in the middle of the limiting block, and the upper end of the cutting knife is located in the groove.

[0020] Preferably, one end of the cutting knife located in the channel is fixedly connected to a chain, and one end of the chain away from the cutting knife is wound with a motor transmission module, and the motor transmission module consists of a driving motor and a roller shaft, and the driving motor is mounted on the first bracket, and the output end of the driving motor is fixedly connected to the roller shaft, and the roller shaft is connected to the first bracket bearing, and the outer wall of the roller shaft is wound with the chain;

[0021] A bracket extending into the interior of the limiting module is installed at the center position of the top surface of the base.

[0022] A method for using an MPP power pipe cutting device for power construction, the method for using is as follows:

[0023] S1. In the initial state, a single arc plate connected to the rotating shaft is flipped downward to place the MPP power pipe body on the top surface of the bracket, completing the placement operation of the MPP power pipe body to be cut;

[0024] S2, start the servo motor to drive the single arc plate to flip through the rotating shaft, so that the two arc plates can be butted together to relatively seal the outer wall of the MPP power pipe body to be cut;

[0025] S3. The spur gear will drive the meshing gear ring to rotate synchronously with the rotation of the shaft. While the gear ring is rotating, the arc-shaped protrusion on its inner wall will gradually contact the connecting column and push against the connecting column to drive the positioning block downward, so that the two ends of the positioning block press against the top of the MPP power pipe body from top to bottom, thereby achieving stable positioning of the MPP power pipe body.

[0026] S4, start the motor transmission module, and drive the cutting knife downward in the groove of the limit block through the chain. At this time, one side of the cutting knife will cut the MPP power tube body. After the cutting is completed, start the motor transmission module and the servo motor in reverse to release the winding of the cutting knife and release the limit clamping of the MPP power tube body, so that the MPP power tube body can be taken out after cutting.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] The present invention can smoothly complete the cutting of the MPP power pipe body without human assistance by setting the cooperation of structures such as the cutting knife and the limit block. The motor transmission module is started to make one end of the chain wind around the motor transmission module. At the same time, the connection end of the chain and the cutting knife will pull the cutting knife to gradually flip it, thereby completing the cutting of the MPP power pipe body, greatly improving the overall operating efficiency.

[0029] The present invention cooperates with structures such as a gear ring and a downward pressure component, thereby eliminating the need for manual assistance to press the MPP power pipe body to limit the position. The gear ring rotates to make the arc-shaped protrusion on its inner wall gradually contact the connecting column, and the positioning block is driven downward through the connecting column. The two ends of the positioning block will gradually contact the two ends of the outer wall of the MPP power pipe body and apply pressure thereto. The upper and lower limit pressures of the positioning block and the bracket are applied, thereby shortening the time consumed by manual operation and improving efficiency.

[0030] The present invention arranges the coordination of structures such as arc plates and movable modules to relatively seal the outside of the MPP power pipe body undergoing cutting operation, thereby preventing waste chips from splashing and increasing the difficulty of cleaning. The servo motor drives the arc plates to gradually flip from an initial open state through a rotating shaft, so that the two arc plates are butted together to form a "circular tube" shape, so that the waste chips generated by the cutting are temporarily retained in the cavity formed by splicing the two arc plates, and waste chips will not splash during cutting, thereby greatly saving subsequent cleaning time.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] like Figures 1 to 9 As shown, the present invention provides an MPP power pipe cutting device for power construction, comprising a base 1 and an MPP power pipe body 6, and further comprising:

[0043] The limit module 2 is installed on the top of the base 1;

[0044] The cutting module 3 is fixed to the top surface of the base 1 and is closely connected to the inner wall of the limiting module 2;

[0045] The movable module 4 is arranged on both sides of the top of the base 1 and is abutted and connected with a pressing component 5;

[0046] The limiting module 2 includes an arc plate 21, the bottom of the arc plate 21 is fixedly connected to the top of the base 1, a protective pad 22 is fixedly installed inside the arc plate 21, and a movable groove 23 for enabling the cutting module 3 to move is opened in the middle of the arc plate 21;

[0047] The movable module 4 includes a fixed ring 44 and a rotating shaft 42 fixed to the base 1. A gear ring 45 is slidably engaged on one side of the fixed ring 44. The arc plate 21 is connected to the base 1 through the rotating shaft 42.

[0048] The pressing assembly 5 comprises a positioning block 51 , both ends of which extend into the interior of the fixing ring 44 , and connecting columns 53 which are in contact with the gear ring 45 are fixedly mounted on both sides of the positioning block 51 .

[0049] like Figure 2 and Fig. 9 As shown, the arc plates 21, the protective pads 22 and the movable grooves 23 are each provided in two groups, and are all symmetrical with respect to the longitudinal center axis of the base 1, and the contact ends of the two groups of arc plates 21 are clamped.

[0050] By adopting the above solution, after the two sets of arc plates 21 are butt-jointed, a shape similar to a "circular tube" will be formed, which can provide cutting protection for the MPP power pipe to be cut later, and avoid the waste generated during the cutting process from splashing and scattering, which is inconvenient for subsequent collection.

[0051] like Figure 2 As shown, the lower ends of the inner cavities of the two arc plates 21 are provided with discharge troughs for the impurities produced by cutting to fall down, and the bottoms of the arc plates 21 are connected to the movable module 4 .

[0052] like Figure 2 and Figure 3 As shown, the movable module 4 includes a servo motor 41 mounted on the base 1, the output end of the servo motor 41 is fixedly connected to the rotating shaft 42, the outer walls of both ends of the rotating shaft 42 are sleeved with spur gears 43, and the outer wall of the spur gear 43 is meshed with a gear ring 45;

[0053] The rotating shaft 42 is fixedly connected to one side arc plate 21 .

[0054] The above scheme is adopted: the servo motor 41 drives the rotating shaft 42 to rotate through its output end, and the rotating shaft 42 will drive the single arc plate 21 to flip over. When the arc plate 21 connected to the rotating shaft 42 flips downward, the two arc plates 21 will be in an open state, and the MPP power tube body 6 can be placed inside the two arc plates 21. Conversely, when the arc plate 21 connected to the rotating shaft 42 flips upward, the two rotating shafts 42 are connected, and the relative closure of the outside of the MPP power tube body 6 can be achieved.

[0055] like Figure 6 As shown, an arc-shaped protrusion is provided inside the gear ring 45 , and the outer wall of the arc-shaped protrusion abuts against the connecting column 53 .

[0056] With the above solution, when the gear ring 45 rotates, the arc-shaped protrusions on its inner wall will rotate synchronously. When the arc-shaped protrusions come into contact with the connecting pillars 53, they will gradually press down the connecting pillars 53, so that the connecting pillars 53 drive the positioning blocks 51 downward.

[0057] like Figure 4 As shown, the top surface of the positioning block 51 that passes through one end of the interior of the fixing ring 44 is provided with a first spring 52 , the top of the first spring 52 is fixedly connected to the top surface of the inner cavity of the fixing ring 44 , and the positioning block 51 is elastically connected to the fixing ring 44 through the first spring 52 .

[0058] The above scheme is adopted: when the connecting column 53 is resisted by the arc-shaped protrusion on the inner wall of the gear ring 45 and drives the positioning block 51 downward, the first spring 52 is in a stretched state. On the contrary, when the arc-shaped protrusion on the inner wall of the gear ring 45 does not contact the connecting column 53, the stretched first spring 52 will release the elastic force and drive the positioning block 51 to reset upward.

[0059] like Figure 1 , Figure 2 , Figure 5 and Figures 7 to 9 As shown, the cutting module 3 includes a first bracket 31 and a second bracket 32. The first bracket 31 and the second bracket 32 ​​are both fixed to the base 1. A limit block 34 and a motor transmission module 36 are respectively installed on the top of the first bracket 31. A cutting knife 33 is hinged on the top of the second bracket 32.

[0060] like Figure 8 As shown, a groove is provided in the middle of the limiting block 34 to allow the cutting knife 33 to flip and move, and the upper end of the cutting knife 33 is located in the groove.

[0061] like Figure 7 and Figure 8 As shown, one end of the cutting blade 33 located in the groove is fixedly connected with a chain 35, and the end of the chain 35 away from the cutting blade 33 is wound with a motor transmission module 36. The motor transmission module 36 consists of a driving motor and a roller shaft. The driving motor is installed on the first bracket 31, and the output end of the driving motor is fixedly connected to the roller shaft. The roller shaft is connected to the bearing of the first bracket 31, and the outer wall of the roller shaft is wound with the chain 35.

[0062] A bracket 7 extending into the interior of the limiting module 2 is installed at the center of the top surface of the base 1 .

[0063] The above scheme is adopted: the motor transmission module 36 is operated so that its output end drives the roller to rotate together. At this time, the chain 35 will be rolled up on the roller of the motor transmission module 36, and then the chain 35 drives the cutting knife 33 to rotate with the hinged end with the second bracket 32 ​​as the axis, and the cutting knife 33 cuts the MPP power tube body 6, and the bracket 7 supports the bottom of the MPP power tube body 6 to improve the cutting stability.

[0064] A method for using an MPP power pipe cutting device for power construction, the method of use is as follows:

[0065] S1. In the initial state, a single arc plate 21 connected to the rotating shaft 42 is turned downward to place the MPP power pipe body 6 on the top surface of the bracket 7, completing the placement operation of the MPP power pipe body 6 to be cut;

[0066] S2, start the servo motor 41, and make it drive the single arc plate 21 to flip through the rotating shaft 42, so that the two arc plates 21 are connected to each other, and the outer wall of the MPP power pipe body 6 to be cut is relatively closed;

[0067] S3, the spur gear 43 will drive the meshing gear ring 45 to rotate synchronously with the rotation of the rotating shaft 42. While the gear ring 45 is rotating, the arc-shaped protrusion on its inner wall will gradually contact the connecting column 53, and push against the connecting column 53 to drive the positioning block 51 downward, so that the two ends of the positioning block 51 press against the top of the MPP power tube body 6 from top to bottom, so as to achieve stable positioning of the MPP power tube body 6;

[0068] S4, start the motor transmission module 36, and drive the cutting knife 33 to move downward in the groove of the limit block 34 through the chain 35. At this time, one side of the cutting knife 33 will cut the MPP power tube body 6. After the cutting is completed, start the motor transmission module 36 and the servo motor 41 in reverse to release the winding of the cutting knife 33, and release the limit clamping of the MPP power tube body 6, so that the MPP power tube body 6 after cutting can be taken out.
