Technical Field

[0001] The utility model belongs to the technical field of drain pipe cutting devices, and particularly relates to a drain pipe cutting device for construction. Background Technique

[0002] During the construction process, it is necessary to cut drain pipes. According to different cutting requirements, different cutting methods can be selected, such as mechanical cutting, laser cutting, etc. Among them, mechanical cutting is the most common cutting method, which cuts the drain pipe by rotating a blade or a grinding wheel.

[0003] For example, the Chinese patent with the publication number CN218362406U discloses a drain pipe cutting device, which includes an operating table and a fixing mechanism; universal wheels are arranged at the four corners of the bottom of the operating table, a control switch is arranged on one side of the operating table, and a push rod is fixedly connected to the other side of the operating table; the fixing mechanism is arranged on the top of the operating table, and the fixing mechanism includes a first fixing block, a second fixing block, a connecting rod, a cylinder, a fixing frame, a sliding groove, a sliding rod, a limiting hole and a limiting rod. A second fixing block is arranged above the first fixing block, a connecting rod is fixedly connected to the top of the second fixing block, and a cylinder is fixedly connected to the top of the connecting rod. The drain pipe cutting device provided by the utility model solves the problem that the traditional fixing method of the cutting device mostly fixes the water pipe through a clamp, and its operation is relatively slow, thereby reducing the work efficiency and not meeting the needs of current users.

[0004] The above patent has the following problems:

[0005] When the above patent is in use, there are some disadvantages, such as: when the above device cuts the drain pipe in cold weather, it may cause the drain pipe to burst, resulting in economic losses. At the same time, when the above device designs a complex drainage system, it cannot cut at multiple angles according to needs, resulting in insufficient use range. In view of this, we propose a drain pipe cutting device for construction. Content of the Utility Model

[0006] The purpose of the utility model is to provide a drain pipe cutting device for construction to solve the problems raised in the above background technique.

[0007] In view of this, the utility model provides a drain pipe cutting device for construction, including:

[0008] Workbench, on which a rotating column is rotatably installed. A first sliding groove is formed in the rotating column. A support arm is slidably installed in the first sliding groove. One end of the support arm penetrates through the first sliding groove and extends to the outside. And a first motor is fixedly installed on one side of the support arm. The output shaft of the first motor penetrates through the support arm and extends to the outside and is fixedly installed with a saw blade.

[0011] Two second sliding grooves are symmetrically formed in the top of the workbench, and both second sliding grooves are located on one side of the rotating column. A sliding plate is slidably installed in the second sliding groove. The top of the sliding plate penetrates through the second sliding groove and extends to the outside. A second threaded rod is rotatably installed in one of the second sliding grooves. One end of the second threaded rod penetrates through one of the sliding plates and extends to the outside. The sliding plate is threadedly connected to the second threaded rod;

[0012] Two turntables are respectively rotatably installed on the opposite sides of the two sliding plates. A power chamber is formed in the turntable. A number of sliding columns are rotatably installed in the power chamber. One ends of the number of sliding columns all penetrate through the power chamber and extend to the outside.

One end of the operating rod penetrates through one of the sliding plates and extends to the outside;

[0013] Two power assemblies are respectively located inside the two turntables and are respectively used to drive the number of sliding columns to slide.

[0014] In this technical solution, when it is necessary to cut a drain pipe in cold weather, first, the drain pipe is sleeved on one side of one of the sliding plates. At the same time, the turntable and several arc-shaped plates will enter the drain pipe. Through the two power components provided, several sliding columns can be driven to slide and move away from each other. At the same time, several springs are compressed and contracted. Several sliding columns respectively drive several arc-shaped plates to slide and move away from each other. Several arc-shaped plates will contact the inner wall of the drain pipe. Through the rubber pads provided, the outer sides of several arc-shaped plates can be closely attached to the inner wall of the drain pipe. Then, slide the other sliding plate towards one of the sliding plates. When the other end of the drain pipe fits against one side of the other sliding plate, the other end of the drain pipe can be fixed through the above operations. Then, rotate the second threaded rod. Under the action of the thread, the second threaded rod drives one of the sliding plates to slide. One of the sliding plates drives the other sliding plate to slide through the cooperation of several arc-shaped plates and the drain pipe. When the drain pipe is displaced to the appropriate position, stop rotating. At this time, start the hot air blower. The hot air blower can heat the position of the drain pipe to be cut.

[0018] In this technical solution, when it is necessary to cut the drain pipe at other angles, first rotate the worm to drive the meshing worm wheel to rotate. The worm wheel drives the rotating column to rotate. Then, the rotating column drives the saw blade to rotate through the support arm. When the saw blade rotates to the appropriate position, stop rotating. Subsequently, start the motor to drive the saw blade to rotate. Finally, rotate the first threaded rod. Under the action of the thread, the first threaded rod drives the support arm to slide downward, and the support arm drives the saw blade to slide downward, so as to perform uniform cutting of the drain pipe at different angles.

[0019] In the above technical solution, further, the power assembly includes:

[0020] The second motor, the second motor is fixedly installed in the power chamber, and a disc is fixedly installed on the output shaft of the second motor. The disc is located between several sliding columns, and several arc-shaped blocks are fixedly installed on the circumferential side of the disc. The other ends of the several sliding columns are respectively in contact with the several arc-shaped blocks.

[0021] In this technical solution, start one of the second motors to drive the corresponding disc to rotate. The disc drives several arc-shaped blocks to rotate. The several arc-shaped blocks will respectively squeeze several sliding columns to slide and move away from each other. At the same time, several springs are squeezed and contracted.
