Description

Technical Field

[0001] This utility model relates to the field of grooving machine technology, and in particular to a fully automatic online grooving machine for plastic-lined composite steel pipes. Background Technology

[0002] Plastic-lined composite steel pipes are characterized by corrosion resistance, good performance against acids, alkalis, salts, and organic solvents, and impact resistance. They are also hygienic, environmentally friendly, easy to install, and have a long service life. The main purpose of groove pressing plastic-lined composite steel pipes is to improve the bonding strength of the pipes, prevent detachment and cracking, and optimize the performance of the pipes to ensure the stability and safety of the pipeline system.

[0003] In existing technologies, when grooving plastic-lined composite steel pipes, the grooving machine requires manual placement of the steel pipe in the grooving area, followed by removal after grooving. This operation is cumbersome, wastes manpower, and is inefficient. Therefore, we propose a fully automatic online grooving machine for plastic-lined composite steel pipes to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems of grooving plastic-lined composite steel pipes, which require manual placement of the steel pipe in the grooving area and removal after grooving, resulting in cumbersome operation, wasted manpower, and low efficiency. Therefore, this invention proposes a fully automatic online grooving machine for plastic-lined composite steel pipes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fully automatic online grooving machine for plastic-lined composite steel pipes includes:

[0007] Base plate;

[0008] The chain conveyor, located on top of the base plate, is used to transport plastic-lined composite steel pipes.

[0009] The movable groove is located at the top of the base plate;

[0010] Two movable plates are slidably installed in the movable slot;

[0011] Two rotating seats are respectively rotatably mounted on two movable plates;

[0012] Two limit plates are fixedly installed on two rotating seats respectively;

[0013] Two insertion posts are fixedly installed on two limiting plates respectively, for insertion into the plastic-lined composite steel pipe;

[0014] An annular groove is provided on one of the two inserts;

[0015] Two first motors are fixedly mounted on two movable plates, and the output shafts of the two first motors are fixedly connected to two rotating seats. The first motors are used to drive the rotating seats to rotate.

[0016] The grooving mechanism is located on one of the two movable plates and works with the annular groove to groove the plastic-lined composite steel pipe.

[0017] The lifting mechanism, located on the base plate, is used to lift the plastic-lined composite steel pipe;

[0018] The jacking mechanism, located on the base plate, is used to move the two movable plates.

[0019] Preferably, the grooving mechanism includes a mounting frame slidably mounted on one side of the movable plate, a rotating rod rotatably mounted on the inner side of the mounting frame, and a roller fixedly mounted on the rotating rod, the roller cooperating with the annular groove.

[0020] Preferably, a second motor is fixedly installed on the inner side of the mounting bracket, and the output shaft of the second motor is fixedly connected to one end of the rotating rod.

[0021] Preferably, a fixed plate is fixedly installed on one side of the movable plate, and a hydraulic cylinder is fixedly installed on the fixed plate. The output shaft of the hydraulic cylinder is fixedly connected to the top of the mounting frame.

[0022] Preferably, the lifting mechanism includes a base fixedly installed in the movable groove, a lifting plate on the top of the base, and an arc-shaped notch on the top of the lifting plate.

[0023] Preferably, a lifting cylinder is fixedly installed on the base, and the output shaft of the lifting cylinder is fixedly connected to the bottom of the lifting plate.

[0024] Preferably, the jacking mechanism includes two vertical plates fixedly installed on the top of the base plate, and a jacking cylinder is fixedly installed on one side of each of the two vertical plates. The output shafts of the two jacking cylinders are respectively fixedly connected to the two moving plates.

[0025] Preferably, both movable plates are provided with rotating holes, and the two rotating seats are respectively rotatably installed in the two rotating holes.

[0026] Compared with the prior art, the advantages of this utility model are:

[0027] This solution places the plastic-lined composite steel pipe on a chain conveyor, which transports the plastic-lined composite steel pipe to above the lifting plate. The lifting cylinder then lifts the lifting plate, and the plastic-lined composite steel pipe contacts the arc-shaped notch on the lifting plate, thus lifting the pipe. Then, two jacking cylinders drive two moving plates to move closer together, which in turn drive two rotating seats to move. The rotating seats then drive two limiting plates to move closer together, allowing two inserts to enter the plastic-lined composite steel pipe. The two limiting plates clamp the two ends of the pipe, and then the lifting cylinder drives the lifting plate to move downwards.

[0028] The hydraulic cylinder drives the mounting frame to move downward, which in turn causes the roll to move downward. At the same time, the second motor drives the roll to rotate, so that the roll contacts the plastic-lined composite steel pipe. The two first motors drive the two rotating seats to rotate, and the two rotating seats drive the two limit plates to rotate, which in turn drives the plastic-lined composite steel pipe to rotate. As the roll moves downward slowly, it works with the annular groove to press the plastic-lined composite steel pipe.

[0029] This invention facilitates the transportation of plastic-lined composite steel pipes, delivering them to the pressing position, saving manpower and improving efficiency. Attached Figure Description

[0037] Base plate 1;

[0038] Chain conveyor 17, located on top of base plate 1, is used to transport plastic-lined composite steel pipes;

[0039] The movable groove 10 is located on the top of the base plate 1;

[0040] Two movable plates 2 are slidably installed in the movable slot 10;

[0041] Two rotating seats 3 are respectively rotatably mounted on two movable plates 2;

[0042] Two limiting plates 4 are fixedly installed on two rotating seats 3 respectively;

[0043] Two insert pins 5 are fixedly installed on two limiting plates 4 respectively, and are used to insert into the plastic-lined composite steel pipe;

[0044] An annular groove 6 is provided on one of the two inserts 5;

[0045] Two first motors 7 are fixedly installed on two movable plates 2 respectively. The output shafts of the two first motors 7 are fixedly connected to two rotating seats 3 respectively. The first motors 7 are used to drive the rotating seats 3 to rotate.

[0046] The grooving mechanism is located on one of the two movable plates 2, and works with the annular groove 6 to groove the plastic-lined composite steel pipe.

[0047] A lifting mechanism, located on the base plate 1, is used to lift the plastic-lined composite steel pipe;

[0048] The jacking mechanism, located on the base plate 1, is used to move the two movable plates 2.

[0049] In this embodiment, the grooving mechanism includes a mounting frame 11 that is slidably mounted on one side of the movable plate 2. A rotating rod 12 is rotatably mounted on the inner side of the mounting frame 11. A roller 13 is fixedly mounted on the rotating rod 12. The roller 13 cooperates with the annular groove 6.

[0050] In this embodiment, a second motor 14 is fixedly installed on the inner side of the mounting bracket 11, and the output shaft of the second motor 14 is fixedly connected to one end of the rotating rod 12.

[0051] In this embodiment, a fixed plate 15 is fixedly installed on one side of the movable plate 2, and a hydraulic cylinder 16 is fixedly installed on the fixed plate 15. The output shaft of the hydraulic cylinder 16 is fixedly connected to the top of the mounting bracket 11.

[0052] In this embodiment, the lifting mechanism includes a base 18 fixedly installed in the moving groove 10, a lifting plate 19 on the top of the base 18, and an arc-shaped notch on the top of the lifting plate 19.

[0053] In this embodiment, a lifting cylinder 20 is fixedly installed on the base 18, and the output shaft of the lifting cylinder 20 is fixedly connected to the bottom of the lifting plate 19.

[0054] In this embodiment, the jacking mechanism includes two vertical plates 8 fixedly installed on the top of the base plate 1. A jacking cylinder 9 is fixedly installed on one side of each of the two vertical plates 8, and the output shafts of the two jacking cylinders 9 are fixedly connected to the two moving plates 2 respectively.

[0056] In this embodiment, the plastic-lined composite steel pipe is placed on the chain conveyor 17, which transports the pipe to above the lifting plate 19. The lifting cylinder 20 then lifts the lifting plate 19, bringing the plastic-lined composite steel pipe into contact with the arc-shaped notch on the lifting plate 19. This lifts the pipe, and then two jacking cylinders 9 move two moving plates 2 closer together. These moving plates 2 move two rotating seats 3, which in turn move two limiting plates 4 closer together, allowing the two inserts 5 to enter the plastic-lined composite steel pipe. Two limiting plates 4 clamp the two ends of the plastic-lined composite steel pipe. Then, the lifting cylinder 20 drives the lifting plate 19 to move downward.

At the same time, the second motor 14 drives the roller 13 to rotate, so that the roller 13 contacts the plastic-lined composite steel pipe. The two first motors 7 drive the two rotating seats 3 to rotate, and the two rotating seats 3 drive the two limiting plates 4 to rotate, thereby driving the plastic-lined composite steel pipe to rotate. As the roller 13 slowly moves downward, it cooperates with the annular groove 6 to press the plastic-lined composite steel pipe.
