[0036] See also Figure 1-Figure 3 As shown, this embodiment is a tensioned membrane rope wire saw static cutting device, comprising:

[0037] A main body assembly, the main body assembly comprising a rotating shaft 16;

[0038] The main assembly also includes a motor 11, a fixing platform 12, a first rotating wheel 13, a rope saw 14, and a connecting block 15;

[0039] One end of the connecting block 15 is fixed to one side of the outer surface of the rotating shaft 16, the fixing platform 12 is fixedly connected to one side of the outer surface of the connecting block 15, the motor 11 is fixedly installed on the upper surface of the fixing platform 12, the first rotating wheel 13 is connected to the output end of the motor 11, and the rope saw 14 is installed inside the first rotating wheel 13;

[0040] The motor 11 provides the necessary power for the whole device. When the motor 11 is started, the first rotating wheel 13 will start to rotate, thereby driving the rope saw 14 to rotate at a high speed. The rope saw 14 is a rope-shaped cutting tool made of steel wire or synthetic material coated with diamond particles. It is installed inside the first rotating wheel 13 and moves with the rotation of the first rotating wheel 13 to accurately cut the tension film, etc.

[0041] An opening and closing assembly, the opening and closing assembly comprising a first movable plate 21, a second rotating wheel 211, a second movable plate 22, and a third rotating wheel 221;

[0042] One end of the first movable plate 21 passes through the outer surface of the rotating shaft 16, the second rotating wheel 211 rotates and passes through the outer surface of the other end of the first movable plate 21, one end of the second movable plate 22 rotates and passes through the outer surface of the rotating shaft 16, and the third rotating wheel 221 is rotatably mounted on the outer surface of the other end of the second movable plate 22;

[0043] The first movable plate 21 can rotate around the rotating shaft 16 to adjust the position and tension of the rope saw 14. The second rotating wheel 211 is used to guide the direction of the rope saw 14 or to increase the tension of the rope saw 14.

[0044] The second movable plate 22 cooperates with the first movable plate 21 to maintain the stability of the rope saw 14 . The third rotating wheel 221 is the same as the second rotating wheel 211 and assists the movement of the rope saw 14 .

[0045] A first connecting plate 23 is fixed to the upper surface of the connecting block 15, a first connecting shaft 231 is fixed to one side of the outer surface of the first connecting plate 23, a first electric push rod 24 is movably mounted on the outer surface of the first connecting shaft 231, and a second connecting shaft 25 is rotatably penetrated through the other end of the first electric push rod 24, a second connecting plate 26 is fixedly mounted on the lower surface of the connecting block 15, a third connecting shaft 261 is fixed to the outer surface of the second connecting plate 26, a second electric push rod 27 is rotatably penetrated through the outer surface of the third connecting shaft 261, and a fourth connecting shaft 28 is penetrated through the other end of the second electric push rod 27;

[0046] The first connecting plate 23 and the first connecting shaft 231 are used to connect and fix the first electric push rod 24, so as to ensure that the first electric push rod 24 can work smoothly and transmit power;

[0047] Working principle:

[0048] When making a cut;

[0049] The staff can start the first electric push rod 24 and the second electric push rod 27 through the external control module;

[0050] When the first electric push rod 24 and the second electric push rod 27 are extended, the first electric push rod 24 and the second electric push rod 27 drive the first movable plate 21 and the second movable plate 22 to open upward and downward, and open the rope saw 14;

[0051] Next, the staff starts the motor 11 through the external control module, and the motor 11 drives the first rotating wheel 13 to rotate;

[0052] The first rotating wheel 13 rotates and drives the rope saw 14 to rotate, and at the same time drives the second rotating wheel 211 and the third rotating wheel 221 to rotate, and synchronously drives the rope saw 14 to rotate;

[0053] This step cuts the tensioned membrane to improve cutting accuracy.

[0054] See also Figure 4 As shown, this embodiment is based on the above embodiment 1 and also includes:

[0055] Active components;

[0056] The movable assembly includes a mounting plate 31, a third electric push rod 32, a mounting frame 33, a handle 34, and a bottom wheel 35;

[0057] The mounting plate 31 is fixed to the lower surface of the fixing platform 12, the third electric push rod 32 is fixedly connected to the lower surface of the mounting plate 31, the mounting frame 33 is fixed to the lower surface of the third electric push rod 32, the handle 34 is connected to one side of the outer surface of the mounting frame 33, and the bottom wheel 35 is connected to the lower surface of the mounting frame 33;

[0058] The mounting plate 31 is used as a platform connected to the fixed platform 12 to stabilize and support the platform. The third electric push rod 32 adjusts the position of the fixed platform 12 through telescopic movement, thereby changing the height of the rope saw 14. The bottom wheel 35 is used to support the entire movable assembly to ensure its stability during operation and to guide the direction of the rope saw 14.

[0059] Working principle:

[0060] When the cutting height needs to be adjusted;

[0061] The staff can start the third electric push rod 32 by controlling the external module. As the third electric push rod 32 is extended or shortened, the fixed platform 12 will rise or fall accordingly, thereby adjusting the height of the rope saw to adapt to different cutting positions.

[0062] When the entire device needs to be moved to change the cutting position, the staff can hold the handle 34 and use the bottom wheel 35 as a support to push or pull the entire device to adjust the position in the horizontal direction. In this way, the device can be easily moved to the desired cutting starting point or continue to move to the next cutting position while keeping the device stable.

[0063] This step does not require frequent manual adjustment of the cutting equipment, reduces physical exertion, improves working conditions and increases overall work efficiency.

[0064] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0065] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
