The four square rods 61 are slidably connected to a pushing seat 63, and the ends of the two pushing seats 63 on the same side away from the clamping plate 62 are welded to the round rod 54 on the same side. Fixed discs 631 are welded to the four square rods 61, and an extrusion spring 64 is fixedly connected between the fixed disc 631 on the same square rod 61 and the clamping plate 62.

[0046] The fixed disc 631 is located on the inner side of the pushing seat 63 .

[0047] In this embodiment, the cutting mechanism includes a support seat 71, the support seat 71 is welded on the square frame 52, a power motor 72 is fixedly connected to the support seat 71, four rotating rollers 73 are rotatably provided on the cutting frame 55, two rotating rods 74 are rotatably connected to the cutting frame 55, the two rotating rods 74 are located obliquely below the two rotating rollers 73 located above, sprocket wheels 75 are fixedly connected to the four rotating rollers 73 and the two rotating rods 74, a chain 76 is wound between the six sprocket wheels 75, the chain 76 is used to drive the sprocket wheels 75, and the sprocket wheels 75 on the four rotating rollers 73 are located inside the chain 76. On the side, the sprockets 75 on the two rotating rods 74 are located on the outside of the chain 76, the two rotating rollers 73 at the top and the ends of the two rotating rods 74 away from the power motor 72 are fixedly connected with a transmission gear 77, the rotating rollers 73 on the same side and the sprockets 75 on the rotating rods 74 are meshed, the four rotating rollers 73 are fixedly connected with a transmission wheel 78, the four transmission wheels 78 are all located on the inner side of the cutting frame 55, and the four transmission wheels 78 are wound with a diamond wire saw 79, the four transmission wheels 78 are used to drive the diamond wire saw 79 to rotate, and the diamond wire saw 79 is used to cut the prefabricated component 3.

[0048] When the prefabricated component 3 needs to be cut, the staff first uses a forklift to place the prefabricated component 3 on the cushion seat 2, and then moves the forklift out of the prefabricated component 3. Then, the electric push rod 51 and the power motor 72 are started, and the push rod retraction of the electric push rod 51 drives the square frame 52 to move downward, and the downward movement of the square frame 52 drives the two extrusion slot plates 53 to move downward, and the two extrusion slot plates 53 move downward through the oblique grooves on the extrusion slot plates 53 to push the two round rods 54 to move toward each other, and the two round rods 54 respectively push the two push seats 63 to move along the square rod 61 toward each other, and the four push seats 63 move toward each other and also push the extrusion spring 64, the clamping plate 62 and the square rod 61 to move together, and the two clamping plates 62 fit the two sides of the prefabricated component 3, and the square frame 52 moves downward, driving the support seat 71 and the cutting frame 55 to move downward together, and the support seat 71 and the cutting frame 55 move downward together. The support seat 71 moves downward, driving the power motor 72 to move downward together, and the cutting frame 55 moves downward, driving the rotating roller 73, the rotating rod 74, the sprocket 75, the chain 76, the transmission gear 77, the transmission wheel 78 and the diamond wire saw 79 to move downward together. The push rod of the electric push rod 51 drives the square frame 52, the two extrusion slot plates 53, the support seat 71, the cutting frame 55 and the diamond wire saw 79 to move downward together, and then first clamp the prefabricated component 3, and then push the diamond wire saw 79 to cut, the two extrusion slot plates 53 continue to move downward, and the four pushing seats 63 continue to push the extrusion spring 64, the clamping plate 62 and the square rod 61 to move together in a direction close to each other, and the two clamping plates 62 clamp the two sides of the prefabricated component 3, and then limit the prefabricated component 3, so that the prefabricated component 3 can be stably cut later, thereby improving the stability of the prefabricated component during cutting.

[0049] Secondly, the output shaft of the power motor 72 rotates forwardly, driving the rotating roller 73 near the output shaft of the power motor 72 and one of the transmission gears 77 on the side of the cutting frame 55 to rotate forwardly. The forward rotation of one of the transmission gears 77 on the side of the cutting frame 55 drives the rotating rod 74 near the power motor 72 and another transmission gear 77 on the side of the cutting frame 55 to rotate reversely. The rotating roller 73 and the sprocket 75 near the output shaft of the power motor 72 rotate forwardly, and the rotating rod 74 and the sprocket 75 near the power motor 72 rotate reversely, driving the chain 76 to rotate. The rotation of the chain 76 drives the other rotating rollers 73 and the sprocket 75 on the other rotating rollers 73 to rotate forwardly. The rotation of the chain 76 also drives the rotating rod 74 and the sprocket 75 on the rotating rod 74 to rotate reversely. The four rotating rollers 73 are driven to rotate forward at the same time through the chain 76. The positive rotation of each rotating roller 73 drives the transmission wheel 78 to rotate, and the rotation of the four transmission wheels 78 drives the diamond wire saw 79 to rotate. The cutting frame 55 moves downward to drive the lowest points of the four transmission wheels 78 and the diamond wire saw 79 to contact the upper surface of the prefabricated component 3. The cutting frame 55 continues to drive the four transmission wheels 78 and the diamond wire saw 79 to move downward, and the lowest point of the diamond wire saw 79 cuts the prefabricated component 3. When the cutting frame 55 moves downward to the lowest point, the lowest point of the diamond wire saw 79 is located in the middle groove of the cushion seat 2. Through the high-speed rotation of the diamond wire saw and the characteristics of the diamond wire saw, the prefabricated component can be quickly cut while ensuring the flatness of the cutting surface of the prefabricated component by the diamond wire saw, thereby improving the cutting efficiency of the prefabricated component.

[0050] In addition, after the prefabricated component 3 is cut, the staff starts the electric push rod 51 to reset and shut down the power motor 72. The push rod of the electric push rod 51 resets upward to drive the square frame 52 and the two extrusion slot plates 53. The reset of the square frame 52 drives the four transmission wheels 78 and the diamond wire saw 79 to move upward together. The lowest point of the diamond wire saw 79 resets along the cutting line cut by the prefabricated component 3. The power motor 72 is shut down and no longer drives the rotating roller 73 and the transmission gear 77 to rotate. The diamond wire saw 79 also stops rotating. When the lowest point of the diamond wire saw 79 is out of the prefabricated component 3, the power motor 72 is turned off and no longer drives the rotating roller 73 and the transmission gear 77 to rotate. The diamond wire saw 79 also stops rotating. When the prefabricated component 3 is being manufactured, the two extrusion slot plates 53 move downward and no longer squeeze the two round rods 54 and the four pushing seats 63. The four pushing seats 63 are all reset under the action of the extrusion springs 64. The four pushing seats 63 reset and push the fixed disc 631, the square rod 61 and the clamping plate 62 to reset together. The two clamping plates 62 reset and no longer clamp the prefabricated component 3. When the push rod of the electric push rod 51 is reset to the initial state, the two clamping plates 62 and the diamond wire saw 79 also return to the initial state. Finally, an external forklift is used to move the prefabricated component 3 after cutting away from the cushion seat 2.

[0051] Embodiment 2

[0052] The second embodiment of the present invention also provides a cutting and forming device for prefabricated components of an underground pipe gallery, which is basically similar to the cutting and forming device shown in the first embodiment, except that:

[0053] In this embodiment, please refer to Figure 7 The cutting and forming device shown in this embodiment also includes a limiting mechanism, which is arranged on the clamping plate 62.

The upper side of the clamping strip 81 in the vertical groove above the clamping plate 62 is fixedly connected to the vertical groove above the clamping plate 62. A compression spring 83 is fixedly connected, and a compression spring 83 is fixedly connected between the lower side of the clamping strip 81 in the vertical groove below the clamping plate 62 and the vertical groove below the clamping plate 62.

A return spring 86 is fixedly connected between the clamping rod 85 and the fixing frame 84, and a moving rod 87 is welded between the two clamping rods 85 on the same side. A moving groove plate 88 is welded on the side away from each other of the two pushing seats 63 on the same fixed plate 4, and each moving groove plate 88 is opened with an oblique groove, and the moving rod 87 on the same side is located in the oblique groove of the moving groove plate 88.

[0054] The four pressing strips 81 at the bottom are located in two grooves of the cushion seat 2 .

[0055] When the cutting and forming device shown in this embodiment is in use, the two clamping plates 62 on both sides move in a direction approaching each other, driving the pressing strips 81 and the moving wheels 82 to move together. Under the action of eight compression springs 83, the eight pressing strips 81 and the eight moving wheels 82 move so that the bottoms of the eight moving wheels 82 move along the two inclined surfaces at the upper and lower parts of the two fixed plates 4 respectively. The two inclined surfaces at the upper and lower parts of the two fixed plates 4 no longer squeeze the eight pressing strips 81 and the eight moving wheels 82. Under the action of the compression springs 83, the four pressing strips 81 respectively press the upper and lower surfaces of the prefabricated component 3, and the four pushing seats 63 continue to move in a direction approaching each other. The four pushing seats 63 all drive the moving slot plate 88 to move, and the moving slot plate 88 moves through the oblique groove to squeeze the moving rod 87 in the direction close to the pressing strip 81. The two ends of the four moving rods 87 respectively drive the clamping rods 85 to clamp into the pressing strips The reset spring 86 is compressed in the slot of 81 and is clamped into the slot of the clamping strip 81 through the clamping rod 85, so that the eight clamping strips 81 can clamp and limit the top and bottom of the prefabricated component 3 respectively, so that the prefabricated component 3 can be cut more stably later, further improving the stability of the prefabricated component during cutting. After the cutting of the prefabricated component 3 is completed, the four pushing seats 63 are reset and all drive the movable slot plate 88 to reset, the movable slot plate 88 is reset and drives the movable rod 87 to reset, the movable rod 87 is reset and drives the clamping rod 85 to reset, the reset spring 86 is reset and also drives the clamping rod 85 to reset, the clamping rod 85 is reset and no longer clamps the clamping strip 81, the two clamping plates 62 on both sides are reset and drive the eight clamping strips 81 and the eight moving wheels 82 to reset, the eight moving wheels 82 move along the two inclined surfaces at the upper and lower parts of the two fixed plates 4 respectively, and the eight clamping strips 81 squeeze the eight compression springs 83 respectively.

[0056] Embodiment 3

[0057] The third embodiment of the present invention also provides a cutting and forming device for prefabricated components of an underground pipe gallery, which is basically similar to the cutting and forming device shown in the second embodiment, except that:

[0058] In this embodiment, please refer to Figure 8 Combined with Figure 3 The cutting and forming device shown in this embodiment also includes a movable wheel 9. Four movable wheels 9 are rotatably connected to the middle part of each clamping strip 81. The four movable wheels 9 on the clamping strip 81 are respectively located on both sides of the clamping plate 62. The movable wheels 9 are used to reduce the friction between the clamping strip 81 and the clamping plate 62.

[0059] When the cutting and forming device shown in this embodiment is in use, the eight pressing strips 81 move along the two vertical grooves on the four clamping plates 62 respectively. The movement of each pressing strip 81 drives the four movable wheels 9 to move. The four movable wheels 9 move along the two sides of the clamping plate 62. The movable wheels 9 contact the two sides of the clamping plate 62, thereby reducing the friction between the pressing strips 81 and the two sides of the clamping plate 62, so that the pressing strips 81 can move along the two vertical grooves of the clamping plate 62 more smoothly.
