Description

Technical Field

[0001] This invention relates to the field of civil engineering, and more specifically to a semi-circular section assembly for water pipes in civil engineering. Background Technology

[0002] In civil engineering, it is often necessary to construct temporary ditches. During the construction of temporary ditches, the pipes need to be cut in half horizontally to form an arc-shaped ditch for temporary drainage.

[0003] Although there are machines on the market that can cut pipes in half horizontally, some steel pipes need to be cut horizontally to form arc-shaped steel pipes for use in water conservancy channels. When cutting pipes horizontally, the cutting head usually cuts the pipes horizontally, which can easily cause the cutting blade to break. The structure is not optimized and the design is not reasonable enough. This application improves the existing technology. Summary of the Invention

[0004] The purpose of this invention is to provide a semi-circular section assembly for water pipes in civil engineering, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a semi-arc sectioning assembly for water pipes in civil engineering, comprising a feeding mechanism and a cross-sectioning mechanism. The feeding mechanism has inner support bars fixedly connected to both the left and right sides of its inner wall. A tooling seat is installed at the bottom of the inner cavity of the feeding mechanism. A motor body is installed at the overlapping part of the tooling seat. A lead screw is installed at the drive end of the motor body. A bearing seat mounting plate is installed at the top of the lead screw. A movable plate is slidably connected to the upper surface of the inner support bars. A gearbox is fixedly connected to the middle part of the upper surface of the movable plate. A motor is installed at the power input part on the back of the gearbox. A gear body is installed at the power output part of the gearbox. A gear is installed on the outer wall of the motor's drive rod, and the gear and gear body are driven by a chain. A support hole seat is installed at the front part of the upper surface of the movable plate. A hole seat is welded to the lower surface of the support hole seat. The shaft of the gear body passes through the central opening of the hole seat.

[0006] As a further embodiment of the present invention: a tooling block is installed on the front part of the upper surface of the feeding mechanism, a through hole is opened in the center of the back of the tooling block, a protective plate is fixedly connected to the outer wall of the tooling block, and a steel pipe to be processed is installed in the slot of the through hole.

[0007] As a further embodiment of the present invention: a screw hole seat is welded to the lower left wall of the cross sectioning mechanism, and cross bolts are installed on both the left and right sides of the upper surface of the screw hole seat. A steel pipe to be processed is sleeved on the outer wall of the vertical rod of the cross bolt, and a pipe sleeve is installed at one end of the steel pipe to be processed. A conical groove block is provided on the lower surface of the conical groove block, and the conical groove block is fixedly connected to the side wall of the cross sectioning mechanism.

[0008] As a further embodiment of the present invention: a housing is installed on one side of the transverse sectioning mechanism, a bushing is installed on the upper left side of the inner side of the housing, a rotating shaft is installed at the axial center of the bushing, a bearing cylinder is installed at the other end of the rotating shaft, a lead screw is installed at the drive end of the housing, a drive rod is installed on the left side of the outer wall of the lead screw, and the drive rod is fixed to the side wall of the housing.

[0009] As a further embodiment of the present invention: slide rails are installed on both the left and right sides of the lower inner part of the chassis, and a base is slidably connected to the upper surface of the slide rails.

[0010] As a further embodiment of the present invention: a longitudinal push plate is installed on the upper surface of the base, a support seat is fixedly connected to the upper surface of the longitudinal push plate, a spring seat is fixedly connected to the upper surface of the support seat, a first gear and a second gear are respectively installed on the back of the spring seat, a shaft is fixedly connected to one end of the controller, a cutting blade is fixedly connected to the top end of the shaft, and a protective plate is installed on the front surface of the spring seat.

[0011] As a further embodiment of the present invention: a lead screw sleeve is installed on the outer wall of the lead screw, and a base is provided above the lead screw sleeve, the base being fixedly connected to the outer wall of the lead screw sleeve.

[0012] As a further embodiment of the present invention: a mounting rod is fixedly connected to the upper inner part of the chassis, and a controller is fixedly connected to the outer wall of the mounting rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] In this invention, the lead screw of the control unit rotates. Since the lead screw sleeve, which is threaded onto the outer wall of the lead screw, is fixed to the lower surface of the base, the base will move back and forth along the lead screw's rotation trajectory. When the base reaches the end of the steel pipe to be processed, the first gear is controlled to operate. The first gear connects to the second gear via a chain, thereby controlling the rotation of the second gear. As the second gear rotates, the shaft connected to one end of the second gear will drive the cutting blade to rotate, thus performing a transverse cut on the diameter of the steel pipe to be processed. The bushing installed on one side of the control unit is connected to the rotating shaft, which can brake the rotating shaft to rotate. When the rotating shaft rotates, it will drive the steel pipe to be processed to move back and forth in the groove on the upper surface of the conical groove block. Since the rotating shaft and the surface of the steel pipe to be processed are in contact, the steel pipe to be processed can move forward and backward. Its structure is more optimized and its design is more reasonable.

[0015] In this invention, the control motor drives the lead screw to rotate. The lead screw sleeve, threaded onto the lead screw, mates with the movable plate. Simultaneously, the lower surface of the movable plate and the upper surface of the inner support bar are slidably connected, ensuring that the movable plate can only move back and forth and will not rotate with the lead screw. A gearbox mounted on the upper surface of the movable plate works in conjunction with the motor. After the motor operates, its drive shaft drives the gear body to rotate via a chain. The shaft of the gear body mates with the steel pipe to be processed. The steel pipe to be processed is positioned on one side of the cutting blade through the slots of the hole seat and the through hole. When cutting the steel pipe, the control cross bolt is twisted on the screw hole seat, and the connecting bar connected to the outer wall of the screw hole seat moves downward and compresses the outer wall of the steel pipe to be processed. After the rotation angle of the steel pipe to be processed is pre-adjusted, the compression of the connecting bar by the cross bolt facilitates cutting. Attached Figure Description

[0026] The working principle of this invention is as follows: When in use, the motor body 33 is controlled to operate, which drives the lead screw body 41 to rotate. The lead screw sleeve threaded on the lead screw body 41 is connected to the movable plate 30. At the same time, the lower surface of the movable plate 30 on the left and right sides and the upper surface of the inner support bar 31 are slidably connected, thereby ensuring that the movable plate 30 can only move back and forth and will not rotate with the lead screw body 41.

[0027] The gearbox 34 mounted on the upper surface of the movable plate 30 is used in conjunction with the motor 32. After the motor 32 is in operation, its drive shaft drives the gear body 35 to rotate through the chain. The shaft of the gear body 35 is connected to the steel pipe 15 to be processed. At the same time, the steel pipe 15 to be processed is located on one side of the cutting blade 29 through the slot of the hole seat 40 and the slot of the through hole 37.

[0028] When cutting the steel pipe 15 to be processed, the cross bolt 13 is controlled to twist on the screw hole seat 12, and the connecting strip 11 connected to the outer wall of the screw hole seat 12 moves downward and squeezes the outer wall of the steel pipe 15 to be processed. After the rotation angle of the steel pipe 15 to be processed is adjusted in advance, the connecting strip 11 is squeezed by the cross bolt 13 to facilitate cutting.

[0029] The lead screw 19 of the drive unit of the control box 3 rotates. The lead screw sleeve threaded to the outer wall of the lead screw 19 is fixed to the lower surface of the base 20. Under the rotation trajectory of the lead screw 19, the base 20 will move back and forth. When the base 20 reaches the end of the steel pipe 15 to be processed, the first gear 23 is controlled to operate. The first gear 23 is connected to the second gear 25 through the chain, thereby realizing the rotation control of the second gear 25. Under the rotation of the second gear 25, the shaft 28 connected to one end of the second gear 25 will drive the cutting blade 29 to rotate and realize the cross-cutting of the diameter of the steel pipe 15 to be processed.

[0030] The bushing 5 installed on one side of the housing 3 is connected to the rotating shaft 7 and can brake the rotating shaft 7 to rotate. When the rotating shaft 7 is rotating, it will drive the steel pipe 15 to be processed to move back and forth in the groove on the upper surface of the conical groove block 14. Since the rotating shaft 7 and the surface of the steel pipe 15 to be processed are in contact, the steel pipe 15 to be processed can move forward and backward.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
