The base 3 is rod-shaped and is arranged along the length of the curtain wall. The pulley block 6 is installed on the base 3, and the base 3 is slidably connected to the ground through the pulley block 6. Two vertical rods 4 are provided and both are arranged in the vertical direction. A connecting seat 7 is fixedly installed at the lower end of the vertical rod 4, and the connecting seat 7 is sleeved outside the base 3 and slidably connected to the base 3. A mounting sleeve 8 is slidably sleeved on the vertical rod 4, and a locking bolt 9 is threadedly connected to the mounting sleeve 8 on the side facing away from the other vertical rod 4, and the locking bolt 9 passes through the mounting sleeve 8 and presses against the vertical rod 4.

[0039] Reference Figure 2 , the cross bar 5 is arranged in the horizontal direction. The cross bar 5 includes a first rod 10 and two second rods 11, and the two second rods 11 are respectively located at both ends of the first rod 10. One of the second rods 11 is connected to the first rod 10 by a positive thread, and the other second rod 11 is connected to the first rod 10 by a reverse thread. One second rod 11 corresponds to a mounting sleeve 8, and the end of the second rod 11 facing away from the first rod 10 is fixedly installed in its corresponding mounting sleeve 8. By screwing the first rod 10, the second rod 11 can be moved relative to the first rod 10, thereby adjusting the length of the cross bar 5. Two cross bars 5 are provided and are arranged at intervals in the vertical direction. The plane where the cross bar 5 is located is parallel to the plane where the vertical rod 4 is located.

[0040] Reference Figure 2 , the vertical rod 4 and the horizontal rod 5 form a guide rail. A guide seat 12 is slidably connected to the guide rail. A vertical slide groove 13 for accommodating the vertical rod 4 and a horizontal slide groove 14 for accommodating the horizontal rod 5 are provided on the guide seat 12. The vertical slide groove 13 and the horizontal slide groove 14 are not located in the same plane. Connecting grooves 15 for accommodating the mounting sleeve 8 are provided at both ends of the vertical slide groove 13, and the end of the horizontal slide groove 14 is connected to the connecting groove 15, so that the horizontal slide groove 14 is connected to the vertical slide groove 13. A first mounting platform 16 is rotatably connected to the guide seat 12, and the first mounting platform 16 is disc-shaped. A second mounting platform 17 is slidably connected to the first mounting platform 16 along its axial direction. A cutting assembly 18 is installed on the second mounting platform 17 facing the curtain wall side. The cutting assembly 18 can be any equipment that can meet the cutting requirements, such as a cutting machine, a cutting blade plus a motor, etc.

[0041] Before cutting the installation groove 2, according to the position and size of the installation groove 2 to be cut, adjust the length and position of the cross bar 5 to a suitable position by screwing the first rod 10 and the sliding installation sleeve 8. Then push the base 3 to the front of the curtain wall where the installation groove 2 needs to be cut. Slide the second mounting platform 17 relative to the first mounting platform 16 so that the cutting assembly 18 completes the cutting of the curtain wall, and then slide the guide seat 12 along the guide rail. When moving to the connection between the vertical rod 4 and the cross bar 5, manually drive the second mounting platform 17 to move until the cutting assembly 18 leaves the curtain wall, then drive the first mounting platform 16 to rotate 90 degrees, and then drive the second mounting platform 17 to move until the cutting assembly 18 cuts into the curtain wall. Repeat this 4 times to complete the cutting of the installation groove 2, which is easy to operate.

[0042] Reference Figure 2 Specifically, two pulley blocks 6 are provided and symmetrically arranged at both ends of the base 3. The pulley block 6 includes a support wheel 19, a running wheel 20 and a positioning wheel 21 arranged in sequence from the inside to the outside. The positioning wheel 21 is installed below the base 3. The support wheel 19 is a universal wheel with a brake pad. After the base 3 is pushed to the front of the curtain wall to be cut, the brake pad can be directly stepped on, so that the positioning wheel 21 is not easy to move relative to the ground. At this time, the base 3 and the curtain wall are in a relatively fixed state, which is convenient for the subsequent sliding of the vertical rod 4 relative to the base 3.

[0043] Reference Figure 2 and Figure 3 The support wheel 19 is installed below the connecting seat 7. The support wheel 19 is a universal wheel with a brake pad. The support wheel 19 supports the connecting seat 7 so that the connecting seat 7 can slide stably relative to the base 3. At the same time, after the vertical rod 4 moves to a suitable position, the brake pad is stepped on to fix the support wheels 19 to the ground.

[0044] Reference Figure 3 and Figure 4 In order to facilitate the vertical rod 4 to move to a suitable position, the running wheel 20 is connected to the base 3 through the mounting seat 22, and the mounting seat 22 is slidably connected to the base 3. The mounting seat 22 is provided with a brake assembly for stopping the running wheel 20. A thrust spring 24 is provided before the mounting seat 22 and the corresponding vertical rod 4, one end of the thrust spring 24 is fixedly connected to the mounting seat 22 and the other end is fixedly connected to the connecting seat 7. The thrust spring 24 is used to drive the vertical rod 4 to move in a direction away from the mounting seat 22. Under the action of the two thrust springs 24, the guide rail is located at the center between the two running wheels 20. Before cutting, it is only necessary to align the running wheel 20 with the edge of the curtain wall unit 1 to be cut, so that the guide rail can correspond to the center of the curtain wall unit 1, without additional alignment, making the operation more convenient. In order to facilitate the running wheel 20 to align with the edge of the curtain wall unit 1 to be cut, the mounting seat 22 is provided with a positioning protrusion 25 on the side facing the curtain wall, and one end of the positioning protrusion 25 is set with a pointed tip.

[0045] The brake assembly includes a brake block 23, which includes a cam portion 26 rotatably connected to the mounting seat 22 through a rotating shaft and a force-applying portion 27 for being stepped on. The force-applying portion 27 is tangentially arranged along the outer wall of the cam portion 26 and fixedly connected to the outer wall of the cam portion 26. When the brake block 23 rotates relative to the mounting seat 22, the distance between the brake block 23 and the running wheel 20 changes. When the running wheel 20 needs to be parked, it is only necessary to step on the brake block 23 so that the brake block 23 is pressed against the running wheel 20.

[0046] In order to better keep the traveling wheel 20 fixed relative to the curtain wall after parking, a suction cup assembly 28 for auxiliary fixation is also provided on the base 3. The suction cup assembly 28 includes a push rod 29 threadedly connected to the base 3 and a suction cup 30 rotatably connected to one end of the push rod 29. The end of the push rod 29 away from the suction cup 30 passes through the base 3, and the end of the push rod 29 away from the suction cup 30 is provided with a force disc 31. A force transmission disc 32 is coaxially provided on the rotating shaft, and a linkage member for driving the force transmission disc 31 and the force transmission disc 32 to rotate synchronously is provided between the force transmission disc 31 and the force transmission disc 32. The linkage member includes a linkage rod 33, one end of the linkage rod 33 is eccentrically rotatably connected to the force transmission disc 31, and the other end of the linkage rod 33 is eccentrically rotatably connected to the force transmission disc 32. A force application handle is provided on the linkage rod 33 for conveniently applying force to the linkage rod 33.

[0047] When the brake block 23 is stepped on to brake the wheel, the force plate 31 rotates to make the suction cup 30 adsorbed on the curtain wall, so that the running wheel 20 is better fixed relative to the curtain wall, and the operator does not need to perform two operations, thereby improving the operator's operating efficiency.

[0048] The implementation principle of a cutting device for cutting a curtain wall installation groove 2 in the embodiment of the present application is as follows:

[0049] 1. According to the size of the installation groove 2 to be cut and the height of the installation groove 2 to be cut relative to the ground, screw the first rod 10 and the sliding installation sleeve 8 until they are adjusted to a suitable size;

[0050] 2. Push the cutting device directly to the side of the curtain wall unit 1 to be cut, brake the positioning wheel 21, and fix the base 3 relative to the curtain wall;

[0051] 3. Slide the mounting base 22 relative to the base 3 so that the running wheel 20 is aligned with the edge of the curtain wall unit 1 to be cut, and step on the brake block 23 so that the running wheel is braked and the suction cup 30 is adsorbed on the curtain wall unit 1;

[0052] 4. Under the action of the thrust spring 24, the guide rail is pushed to the center position;

[0053] 5. Slide the second mounting platform 17 relative to the first mounting platform 16, so that the cutting assembly 18 completes the cutting of the curtain wall, and then slide the guide seat 12 along the guide rail;

[0054] 6. When the machine moves to the connection point between the vertical rod 4 and the horizontal rod 5, the second mounting platform 17 is manually driven to move until the cutting assembly 18 leaves the curtain wall, and then the first mounting platform 16 is driven to rotate 90 degrees, and then the second mounting platform 17 is driven to move until the cutting assembly 18 cuts into the curtain wall;

[0055] 7. Repeat step 6 until the entire installation groove 2 is cut.

[0056] Embodiment 2:

[0057] The difference between Example 2 and Example 1 is that a driving assembly is provided on the guide seat 12, and the driving assembly includes a driving motor 34, a driving electric cylinder 35 and a control module. The driving motor 34 drives the first mounting platform 16 to rotate relative to the guide seat 12 through gear transmission. The driving electric cylinder 35 is used to drive the second mounting platform 17 to slide relative to the first mounting platform 16. The control module is used to control the power output by the driving motor 34 and the driving electric cylinder 35. A control button 36 is provided on the wall of the connecting groove 15. The control button 36 is electrically connected to the control module.

[0058] When the guide seat 12 moves relative to the guide rail until the mounting sleeve 8 is embedded in the connecting groove 15, the mounting sleeve 8 presses the control button 36; when the control button 36 is pressed, the driving assembly drives the second mounting platform 17 to move until the cutting assembly 18 leaves the curtain wall, then drives the first mounting platform 16 to rotate 90 degrees, and then drives the second mounting platform 17 to move until the cutting assembly 18 cuts into the curtain wall.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
