Description

Technical Field

[0001] This utility model relates to the field of pipeline production technology, specifically to a PE pipeline opening device. Background Technology

[0002] PE pipes are plastic pipes made of polyethylene resin and are widely used in municipal, industrial, and agricultural fields. PE pipes are characterized by their corrosion resistance and excellent flexibility.

[0003] When using PE pipes, in order to add branch pipes or install monitoring devices, it is necessary to use a hole saw to make holes on the circumference of the PE pipe. However, since the commonly used PE pipe is cylindrical, it is difficult to maintain a stable state when making holes. This leads to the hole position shifting easily during the making process, which affects the quality of the making. Summary of the Invention

[0004] This invention addresses the problem of maintaining a stable state during PE pipe drilling by providing a PE pipe drilling device that can limit the PE pipe during drilling, thereby improving the drilling quality.

[0005] To solve the above problems, the technical solution of this utility model is:

[0006] A PE pipe opening device includes a U-shaped plate and limiting components. The upper opening of the U-shaped plate is sealed by a V-shaped plate. A horizontal plate is provided inside the U-shaped plate below the V-shaped plate. Limiting components are symmetrically arranged on the left and right sides of the U-shaped plate. The left limiting component includes a rotating rod and an n-shaped rod. The front and rear ends of the rotating rod pass through and are rotatably connected to the front and rear side plates of the U-shaped plate, respectively. The n-shaped rod is sleeved on the outside of the U-shaped plate with its opening facing downwards. The two ends of the n-shaped rod are fixedly connected to the front and rear ends of the rotating rod, respectively. A driving component is provided on the U-shaped plate to drive the two rotating rods to rotate relative to each other or in opposite directions. An auxiliary component is provided on the horizontal plate to facilitate the PE pipe to rotate circumferentially or move axially around the V-shaped plate. An opening device is provided between the two n-shaped rods and movably positioned directly above the V-shaped plate.

[0007] Furthermore, the rotating rod on each of the limiting members is located inside the U-shaped plate on the lower side of the horizontal plate; the left rotating rod has a spiral groove one on its peripheral wall, and the right rotating rod has a spiral groove two on its peripheral wall, with the spiral groove one and spiral groove two rotating in opposite directions.

[0008] Furthermore, the driving component includes a driving plate and a screw. The driving plate is slidably disposed in the U-shaped plate under the horizontal plate. The left part of the driving plate is fitted outside the left rotating rod through a circular hole, and the right part is fitted outside the right rotating rod through a second circular hole. A first driving block is provided on the circumferential surface of the first circular hole, which extends into the first spiral groove. A second driving block is provided on the circumferential surface of the second circular hole, which extends into the second spiral groove. The rear end of the screw is rotatably connected to the rear side plate of the U-shaped plate, and the front end movably passes through the front side plate of the U-shaped plate. The screw is threadedly connected to the driving plate.

[0009] Furthermore, the V-shaped plate one is provided with a plurality of through holes spaced apart, each through hole being arranged along the bending direction of the V-shaped plate one. The auxiliary component includes a V-shaped plate two and bullseye balls. The V-shaped plate two is provided between the V-shaped plate one and the horizontal plate. The top surface of the horizontal plate is provided with a hydraulic cylinder one for driving the V-shaped plate two to move upward or downward. The top surface of the V-shaped plate two is embedded with a plurality of sets of bullseye balls corresponding to the through holes spaced apart. When the top surface of the V-shaped plate two contacts the bottom surface of the V-shaped plate one, the upper end of each set of bullseye balls passes through the corresponding through hole.

[0010] Furthermore, a vertical plate is connected to the outer rear side of the U-shaped plate, a flat plate is connected to the upper front side of the vertical plate, a hydraulic cylinder is connected to the bottom surface of the flat plate, and an opening device with its output end facing the bend of the V-shaped plate is connected to the piston end of the hydraulic cylinder.

[0011] The beneficial effects of this utility model through the above technical solution are as follows:

[0012] This invention uses a driving component to drive two rotating rods to rotate in opposite directions, enabling the two n-shaped rods to clamp and limit the PE pipe, preventing the PE pipe from shaking and improving the opening quality of the PE pipe.

[0013] The auxiliary component of this invention enables the PE pipe to move axially and rotate circumferentially, and conveniently positions the PE pipe where a hole needs to be made directly below the hole opener. This facilitates the adjustment of the PE pipe position and saves manpower. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] like Figures 1-6 As shown, a PE pipe opening device includes a U-shaped plate 1 and limiting components. The left, right, and upper ends of the U-shaped plate 1 are open. The upper opening of the U-shaped plate 1 is blocked by a V-shaped plate 2. The front and rear ends of the V-shaped plate 2 are respectively connected to the upper ends of the front and rear side plates of the U-shaped plate 1. The opening of the V-shaped plate 2 faces upward. A horizontal plate 3 is provided inside the U-shaped plate 1 on the lower side of the V-shaped plate 2. The horizontal plate is horizontally arranged and its front and rear ends are respectively connected to the front and rear side plates of the U-shaped plate. Limiting components are symmetrically provided on the left and right sides of the U-shaped plate 1. The limiting component on the left side includes a rotating rod 4 and an n-shaped rod 5. The rotating rod 4 is a round rod. The front and rear ends of the rotating rod 4 pass through and are rotatably connected to the front and rear side plates of the U-shaped plate 1, respectively. The n-shaped rod 5 is sleeved on the outside of the U-shaped plate 1 with its opening facing downward. The two ends of the n-shaped rod are fixedly connected to the front and rear ends of the rotating rod 4, respectively. The U-shaped plate 1 is provided with a driving component, which is used to drive the two rotating rods 4 to rotate relative to each other or in opposite directions. The horizontal plate 3 is provided with an auxiliary component, which facilitates the PE pipe to rotate circumferentially or move axially on the V-shaped plate 2. An opening device 6 is provided between the two n-shaped rods 5 and is located directly above the V-shaped plate 2.

[0023] The n-shaped rod 5 is an n-shaped rod formed by bending a round rod. The two vertical rods of the n-shaped rod 5 slide in contact with the front and rear outer sides of the U-shaped plate 1, respectively.

[0024] The rotating rod 4 on each of the limiting members is located inside the U-shaped plate under the horizontal plate 3; the left rotating rod 4 has a spiral groove 7 on its peripheral wall, and the right rotating rod 4 has a spiral groove 8 on its peripheral wall. The spiral grooves 7 and 8 have opposite directions of rotation. The front and rear ends of the spiral grooves 1 and 2 pass through the two ends of the rotating rod respectively.

[0025] The driving component includes a driving plate 9 and a screw 10. The driving plate 9 is a rectangular plate whose upper and lower ends respectively slide in contact with the bottom plate of the horizontal plate 3 and the U-shaped plate 1. The driving plate 9 is slidably disposed in the U-shaped plate 1 below the horizontal plate 3. The left part of the driving plate 9 is fitted over the left rotating rod 4 through a circular hole 11, and the right part is fitted over the right rotating rod 4 through a circular hole 12. A driving block 13 extending into a spiral groove 7 is provided on the circumferential surface of the circular hole 11, and a driving block 14 extending into a spiral groove 8 is provided on the circumferential surface of the circular hole 12. The driving block 1 slides in contact with the spiral groove 1, and the driving block 14 slides in contact with the spiral groove 2. The rear end of the screw 10 is rotatably connected to the rear side plate of the U-shaped plate 1, and the front end moves through the front side plate of the U-shaped plate 1 and connects to the rotating plate. The screw 10 is threadedly connected to the driving plate 9. Figure 3 As shown, spiral groove 7 is right-handed and spiral groove 8 is left-handed. When the screw 10 is rotated, driving the drive plate 9 forward, drive block 13 presses against spiral groove 7 and drive block 24 presses against spiral groove 8. The left rotating rod 4 rotates clockwise and the right rotating rod 4 rotates counterclockwise. At this time, the two rotating rods 4 rotate relative to each other. Similarly, when the screw 10 is rotated in the opposite direction, the left rotating rod 4 rotates counterclockwise and the right rotating rod 4 rotates clockwise. At this time, the two rotating rods 4 rotate in opposite directions.

[0026] The V-shaped plate 2 is provided with a plurality of through holes 18 spaced apart. Each through hole 18 is arranged along the bending direction of the V-shaped plate 2, and the plurality of through holes 18 are spaced apart along the length direction of the V-shaped plate 2. The auxiliary component includes a second V-shaped plate 16 and bullseye balls 17. The second V-shaped plate 16 is provided between the first V-shaped plate 2 and the horizontal plate 3. The second V-shaped plate 16 is the same shape and size as the first V-shaped plate 2. The top surface of the horizontal plate 3 is provided with a hydraulic cylinder 20 for driving the second V-shaped plate 16 to move upward or downward. The top surface of the second V-shaped plate 16 is embedded with a plurality of sets of bullseye balls 17 corresponding to the through holes 18. When the top surface of the second V-shaped plate 16 contacts the bottom surface of the first V-shaped plate 2, the upper end of each set of bullseye balls 17 passes through the corresponding through hole 18.

[0027] A vertical plate 21 is connected to the outer rear side of the U-shaped plate 1. A flat plate 22 is connected to the upper front side of the vertical plate 21. A hydraulic cylinder 23 is connected to the bottom surface of the flat plate 22. An opening device 6 with its output end facing the bend of the V-shaped plate 2 is connected to the piston end of the hydraulic cylinder 23.

[0028] In the initial state, hydraulic cylinder 23 drives the hole opener 6 to move upward to the limit state, and the openings of the two n-shaped rods 5 are both facing downward. Hydraulic cylinder 20 drives V-shaped plate 16 to move upward until it contacts V-shaped plate 2. At this time, the upper end of each set of bullseye balls 17 passes through the corresponding through hole 18.

[0029] In use, the PE pipe requiring a hole is passed through the two n-shaped rods 5 and positioned on the V-shaped plate 1. Since the upper end of each set of bullseye balls 17 passes through the corresponding through hole 18, the lower part of the PE pipe's peripheral wall contacts multiple bullseye balls 17, facilitating the axial displacement and circumferential rotation of the PE pipe. This allows for easy adjustment of the PE pipe's position to be aligned with the output end of the hole opener 6. The hydraulic cylinder 20 drives the V-shaped plate 2 16 downwards until the upper end of the bullseye balls 17 is lower than the V-shaped plate 2. At this point, the lower part of the PE pipe contacts the V-shaped plate 2. Rotation... Screw 10 causes the two rotating rods 4 to rotate in opposite directions. The left n-shaped rod 5 rotates counterclockwise with the connected rotating rod 4, and the upper part of the left n-shaped rod 5 gradually presses against the upper end of the left peripheral wall of the PE pipe. At the same time, the right n-shaped rod 5 rotates clockwise with the connected rotating rod 4, and the upper part of the right n-shaped rod 5 gradually presses against the upper end of the right peripheral wall of the PE pipe. After the upper parts of both n-shaped rods 5 are pressed against the PE pipe, the PE pipe is limited on the V-shaped plate 2. The hydraulic cylinder 23 drives the hole opener 6 in the working state to move downward, so as to open the PE pipe in the stable state.

[0030] After the two n-shaped rods 5 release the PE pipe from their restraints, the hydraulic cylinder 20 drives the V-shaped plate 16 to move upwards until it contacts the V-shaped plate 2. The upper end of each set of bullseye balls 17 passes through the corresponding through hole 18. The PE pipe is supported by multiple bullseye balls, which facilitates the axial displacement or circumferential rotation of the PE pipe to be adjusted to a suitable position. Subsequently, the bullseye balls on the auxiliary component no longer support the PE pipe. After the PE pipe contacts the V-shaped plate 2, the two n-shaped rods 5 are used again to restrain the PE pipe, which makes it easy to open holes in multiple positions of the PE pipe.

However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
