Description

Technical Field

[0001] The present invention relates to the technical field of steel pipe processing, and more particularly to a greenhouse steel pipe cutting device. Background Art

[0002] Steel pipe is a hollow steel product whose length often far exceeds its diameter or circumference. Due to its unique structural characteristics, this steel is widely used in numerous industrial sectors. For example, steel pipe plays a vital role in oil drilling, geological exploration, machinery manufacturing, chemicals, construction, power generation, transportation, vehicle manufacturing, aerospace, shipbuilding, and weapons.

[0003] According to the patent document: CN116175197A, a precise cutting device for processing steel pipes in vegetable greenhouses is disclosed, which relates to the technical field of steel pipe cutting; it includes a base, a bracket is connected to the base, and a feeding and transporting assembly is provided at one end of the base for transporting and feeding the steel pipe; a cutting assembly is provided on the bracket for cutting the steel pipe; a grinding assembly is provided on the other end of the base, and the grinding assembly is used to remove burrs from the steel pipe; it also includes a pushing assembly, which includes a push rod slidingly arranged on the base. When the descending stroke of the cutting assembly exceeds a threshold, the cutting assembly is contacted and squeezed by the push rod to cut off the power transmission, thereby blocking the cutting assembly from continuing to descend, and more effectively preventing accidents.

[0004] Greenhouses are usually built with a large number of steel pipes. These steel pipes not only need to have good load-bearing capacity, but also need to meet precise standards in size and shape to ensure the stability and durability of the greenhouse structure. However, in the actual processing process, the cutting accuracy of the steel pipes directly affects the overall quality of the greenhouse. When cutting steel pipes, a large number of steel pipes usually need to be cut. The lengths of these steel pipes after cutting need to be consistent to meet the high requirements for length consistency at a certain point in the greenhouse construction. The traditional cutting method is usually to clamp the steel pipe and then use a cutting tool to automatically cut it. This cutting method may cause the steel pipe to be clamped in a different position each time, resulting in errors in the cutting length, affecting the precise construction of the greenhouse structure. Summary of the Invention

[0036] When the steel pipe needs to be cut, the steel pipe conveyed by the steel pipe conveying platform 2 falls into the steel pipe placement groove 1127 opened at the top of the outer wall of the steel pipe conveying roller 1126, and then the motor 11212 is started. The output end of the motor 11212 drives the transmission disc 11213 to rotate, and the transmission disc 11213 drives the second transmission disc 11215 to rotate through the crawler 11214. The second transmission disc 11215 drives the columnar rotating cross bar 1110 to rotate, and the columnar rotating cross bar 1110 The convex abutting block 1111 and the gear 1119 at the left end are driven to rotate, and the gear 1119 rotates and then engages the second gear 1121 to rotate. The reduction gear 119 decelerates the gear 1119 when it rotates. At the same time, the second gear 1121 drives the circular rotating disk 1122 and the semicircular rotating disk 1123 to rotate synchronously. The semicircular rotating disk 1123 is periodically stuck in the semicircular notch 1129 as the intermittent rotating disk 1128 rotates. When the circular rotating disk 1122 rotates and drives the column When the cylindrical stop block 1124 rotates and is inserted into the inner wall of one of the U-shaped stop grooves 11210 provided on the intermittent turntable 1128, the rotation of the cylindrical stop block 1124 drives the intermittent turntable 1128 to rotate, and the intermittent turntable 1128 drives the intermittent turntable horizontal rotation rod 1125 to rotate, and the intermittent turntable horizontal rotation rod 1125 drives the steel pipe conveying roller 1126 to rotate, and the steel pipe conveying roller 1126 drives the steel pipe falling into the steel pipe placement groove 1127 to rotate, so that the steel pipe conveying roller 1126 can rotate. The steel pipe placement slot 1127 with the steel pipe dropped thereon rotates toward the bottom. At this time, the steel pipe placement slot 1127 opened on the other side of the steel pipe conveying roller 1126 rotates toward the top to wait for the next steel pipe to be cut. The steel pipe that slides down falls to the top of the cutting table 111 according to its own gravity and rolls forward by inertia to the inside of the two columnar rear limit rod slots 117 opened on the cutting table 111 and the two inverted L-shaped front limit rod slots 116 opened on the top of the blanking inclined plate 112.

[0037] At the same time, the second motor 122 rotates through the cutting disc drive disc 123 and the third crawler 126 to drive the second cutting disc drive disc 127 to drive the cutter disc column rotating cross bar 129 to rotate, thereby rotating the cutter discs 1210 at both ends, and when the two convex abutting blocks 1111 rotate, the top of the two convex abutting blocks 1111 rotates to the bottom, and the two Z-shaped connecting plates 124 are pushed downward by the two convex abutting blocks 1111, and the two Z-shaped connecting plates 124 move downward to drive the columnar limiting rods 125 on both sides of the bottom and the two inverted L-shaped limiting rods 128 on the front side to move downward, and the two column limiting rods The rod 125 and the two inverted L-shaped limiting rods 128 are first inserted into the inner walls of the columnar rear limiting rod slot 117 and the inverted L-shaped front limiting rod slot 116, thereby limiting the steel pipe. When the two convex abutting blocks 1111 continue to rotate, the two convex abutting blocks 1111 continuously abut the two Z-shaped connecting plates 124 to move downward, thereby causing the cross plate 121 and the two rotating cutter discs 1210 to continue to move downward to cut the steel pipe. The two second springs 1211 limit the downward movement distance of the two Z-shaped connecting plates 124, thereby preventing the two cutter discs 1210 from falling too much and causing the top surface of the cutting plate 111 to be damaged.

[0038] After the cutting is completed, the motor 11212 is started again, and the output end of the motor 11212 drives the transmission plate 11213 to continue to rotate. The transmission plate 11213 drives the second transmission plate 11215 to continue to rotate through the crawler belt 11214, and then drives the columnar rotating cross bar 1110 to continue to rotate. As the columnar rotating cross bar 1110 continues to rotate, the convex push block 1111 gradually separates from the bottom of the Z-shaped connecting plate 124. At this time, the elastic force of the second spring 1211 begins to appear, pushing the Z-shaped connecting plate 124 and its attached parts to reset upward, the cutter head column rotating cross bar 129 and the cutter heads 1210 at both ends also rise accordingly, completing the cutting of the steel pipe, and driving the fourth transmission plate 11218 to rotate through the second crawler belt 11217 to make the convex push block column transverse rod 1112 drive the convex push block 1113 to rotate to push the cut steel pipe to the unloading inclined plate 112, and slide along the unloading inclined plate 112 for unloading;

[0039] At the same time, the intermittent turntable 1128 continues to rotate driven by the circular rotating disk 1122 and the semicircular turntable 1123. When the intermittent turntable 1128 continues to rotate, if the semicircular turntable 1123 is stuck in the semicircular notch 1129, the intermittent turntable 1128 remains stationary. At this time, the steel pipe conveying roller 1126 also remains stationary and no longer rotates. This design allows the steel pipe to remain stable during the cutting process, avoiding the impact of the cutting accuracy due to the continuous rotation of the conveying roller. When the columnar stop block 1124 is again stuck in the next U-shaped stop groove 11210, the intermittent turntable 1128 is driven to rotate again, thereby driving the steel pipe conveying roller 1126 to rotate, preparing to convey and cut the next steel pipe.

[0040] In addition, the design of the baffle 1117 ensures that when the steel pipe is conveyed down through the steel pipe conveying platform 2 and stuck in the steel pipe placement groove 1127 on the top of the steel pipe conveying roller 1126, it will not slide directly to the top of the cutting table 111 due to excessive inertia, but will be blocked by the baffle 1117, ensuring that the steel pipe can accurately fall into the steel pipe placement groove 1127. At the same time, the design of the spring 1118 enables the baffle 1117 to have a certain buffer when it is subjected to the impact force of the steel pipe, thereby preventing the baffle 1117 from being damaged due to excessive impact force.

[0041] like Figures 9-10 As shown, the bottom of the triangular unloading platform 21 is fixedly connected to the rear side of the top of the cutting table 111, and the inner wall of the semicircular notch 22 of the unloading platform opened on the front side of the triangular unloading platform 21 is fitted with the rear side of the outer wall of the steel pipe conveying roller 1126. The rear sides of the left and right sides of the triangular unloading platform 21 are fixedly connected to two connecting cross bars 24, and the rear sides of the inner sides of the left and right sets of connecting cross bars 24 are fixedly connected to the conveying platform support vertical rods 25. The tops of the two conveying platform support vertical rods 25 are fixedly connected to the rear sides of the left and right sides of the bottom of the conveying platform 23. The rear side of the right side of the conveying platform 23 is fixedly connected to an inverted L-shaped connecting plate 26, and the top left side of the inverted L-shaped connecting plate 26 is fixedly connected to a hinge block 27. The front side of the right side of the conveying platform 23 is fixedly connected to a conveying platform side plate 28 , a guide transverse plate 29 is fixedly connected to the middle of the left side of the conveying platform side plate 28, and guide grooves 210 are opened on the front and rear sides of the top of the guide transverse plate 29. The inner wall of the hinge block 27 is rotatably connected to the hydraulic push rod adapter block 212, and the front side of the hydraulic push rod adapter block 212 is fixedly connected to the hydraulic push rod 211. The front end of the hydraulic push rod 211 is rotatably connected to the rotating block hinge block 213. The bottom of the rotating block hinge block 213 is fixedly connected to the rotating block 214. The bottoms of the front and rear sides of the rotating block 214 are rotatably connected to the concave lifting plates 215. The outer walls of the two concave lifting plates 215 are slidably connected to the inner walls of the two guide grooves 210 opened in the guide transverse plate 29. The bottoms of the inner sides of the two concave lifting plates 215 are fixedly connected to the transmission platform baffle 216;

[0042] When it is necessary to transport the steel pipes, multiple steel pipes are arranged in sequence on the top of the transport platform 23, and the rear side of the front transmission platform baffle 216 is stuck in the outer wall of the frontmost steel pipe. During transportation, the hydraulic push rod 211 is started, and the hydraulic push rod 211 pulls the hydraulic push rod adapter block 212 to move backward. The hydraulic push rod adapter block 212 drives the hydraulic push rod adapter block 212 in the hinge block 27 to rotate forward. Since the hinge block 27 is connected to the turn block hinge block 213 through the hydraulic push rod 211, the turn block hinge block 213 will move forward and produce a certain inclination, thereby driving the turn block 214 to rotate around its rotation connection point with the concave lifting plate 215, and the rotational motion of the turn block 214 is converted into a concave lifting plate. The concave lifting plate 215 slides in the guide groove 210, and the concave lifting plate 215 rises steadily under the guidance of the guide groove 210, thereby driving the transmission platform baffle 216 to rise. As the transmission platform baffle 216 rises, the rear baffle that was originally stuck on the outer wall of the front steel pipe gradually releases the steel pipe, allowing the steel pipe to be transported on the conveying platform 23. At the same time, the subsequent steel pipes are continued to be stuck by the rear transmission platform baffle 216 to ensure the stability and continuity of the steel pipe transmission. During the entire transmission process, the steel pipe is rolled downward on the front side of the triangular unloading platform 21 by the rolling action of the steel pipe conveying roller 1126 until it is stuck in the steel pipe placement groove 1127 opened on the top of the steel pipe conveying roller 1126.

[0043] Working principle of the present invention: during operation, the hydraulic push rod 211 is first started, and the hydraulic push rod 211 pulls the hydraulic push rod adapter block 212 to move backward, and the hydraulic push rod adapter block 212 drives the hydraulic push rod adapter block 212 part in the hinge block 27 to rotate forward. Since the hinge block 27 is connected to the rotating block hinge block 213 through the hydraulic push rod 211, the rotating block hinge block 213 will move forward and produce a certain inclination, thereby driving the rotating block 214 to rotate around its rotating connection point with the concave lifting plate 215. The rotational motion of the rotating block 214 is converted into the sliding motion of the concave lifting plate 215 in the guide groove 210. The concave lifting plate 215 rises steadily under the guidance of the guide groove 210, thereby The transmission platform baffle 216 is driven to rise. As the transmission platform baffle 216 rises, the rear baffle that was originally stuck on the outer wall of the front steel pipe gradually releases the steel pipe, allowing the steel pipe to be transported on the conveying platform 23. At the same time, the subsequent steel pipes are continued to be stuck by the rear transmission platform baffle 216 to ensure the stability and continuity of the steel pipe transmission. During the entire transmission process, the steel pipe is rolled downward on the front side of the triangular unloading platform 21 by the rolling action of the steel pipe conveying roller 1126 until it is stuck in the steel pipe placement groove 1127 opened on the top of the steel pipe conveying roller 1126. Then, the motor 11212 is started, and the output end of the motor 11212 drives the transmission disk 11213 to rotate. The transmission disk 11213 passes through The crawler belt 11214 drives the second transmission plate 11215 to rotate, and the second transmission plate 11215 drives the columnar rotating cross bar 1110 to rotate. The columnar rotating cross bar 1110 drives the convex abutting block 1111 and the gear 1119 at the left end to rotate. The gear 1119 rotates and then engages the second gear 1121 to rotate. The reduction gear 119 slows down the gear 1119 when it rotates. At the same time, the second gear 1121 drives the circular rotating disk 1122 and the semicircular rotating disk 1123 to rotate synchronously. The semicircular rotating disk 1123 periodically gets stuck in the semicircular notch 1129 as the intermittent rotating disk 1128 rotates. When the circular rotating disk 1122 rotates and drives the columnar abutting block 112 When the intermittent turntable 1128 is rotated and inserted into the inner wall of one of the U-shaped abutting grooves 11210 provided on the intermittent turntable 1128, the rotation of the columnar abutting block 1124 drives the intermittent turntable 1128 to rotate, and the intermittent turntable 1128 drives the intermittent turntable horizontal rotation rod 1125 to rotate, and the intermittent turntable horizontal rotation rod 1125 drives the steel pipe conveying roller 1126 to rotate, and the steel pipe conveying roller 1126 drives the steel pipe dropped into the steel pipe placement groove 1127 to rotate, so that the steel pipe placement groove 1127 with the steel pipe dropped by the steel pipe conveying roller 1126 rotates toward the bottom. At this time, the hydraulic push rod 211 is activated again to convey another steel pipe to the steel pipe placement groove 1127 provided on the other side of the steel pipe conveying roller 1126.The steel pipe falling down falls to the top of the cutting table plate 111 according to its own gravity and rolls forward to the inside of the two columnar rear limiting rod through slots 117 and the two inverted L-shaped front limiting rod through slots 116 opened at the top of the blanking inclined plate 112 by inertia, at the same time, the second motor 122 rotates the cutting cutter head transmission disc 123, the third track 126 drives the second cutting cutter head transmission disc 127, the cutter head columnar rotary cross rod 129 is rotated, and then the two ends of the cutter head 1210 is rotated, and when the two convex abutting blocks 1111 rotate, the top of the two convex abutting blocks 1111 rotates to the bottom, and the two Z-shaped connecting plates 124 are moved downward by the two convex abutting blocks 1111, the two Z-shaped connecting plates 124 are moved downward, and then the bottom two side columnar limiting rods 125 and the front two inverted L-shaped limiting rods 128 are moved downward, the two columnar limiting rods 125 and the two inverted L-shaped limiting rods 128 are first clamped into the inner wall of the columnar rear limiting rod through slot 117 and the inverted L-shaped front limiting rod through slot 116, and then the steel pipe is limited, and when the two convex abutting blocks 1111 continue to rotate, the two convex abutting blocks 1111 continue to abut against the two Z-shaped connecting plates 124 to move downward, and then the cross plate 121 and the two cutter heads 1210 rotating continuously move downward to cut the steel pipe, after cutting, the motor 11212 is started again, the output end of the motor 11212 drives the transmission disc 11213 to continue to rotate, the transmission disc 11213 drives the second transmission disc 11215 to continue to rotate through the track 11214, and then drives the columnar rotary cross rod 1110 to continue to rotate, with the continuous rotation of the columnar rotary cross rod 1110, the convex abutting block 1111 gradually separates from the bottom of the Z-shaped connecting plate 124, at this time, the elastic force of the second spring 1211 begins to appear, pushing the Z-shaped connecting plate 124 and its attached parts to reset upward, the cutter head columnar rotary cross rod 129 and the cutter head 1210 at both ends also rise, ending the cutting of the steel pipe, and the fourth transmission disc 11218 is rotated by the second track 11217 to drive the convex push block columnar cross rod 1112 to rotate the convex push block 1113 to push the cut steel pipe to the blanking inclined plate 112, and slide down along the blanking inclined plate 112 for blanking, at the same time, when the columnar abutting block 1124 is clamped into the next U-shaped abutting groove 11210, the intermittent turntable 1128 is driven to rotate again, and then drives the steel pipe conveying roller 1126 to rotate, preparing for the conveying and cutting of the next steel pipe, and so on, until all the steel pipes placed on the top of the conveying table 23 are cut.
