DETAILED DESCRIPTION

[0023] like Figures 1 to 5 As shown, a rock slab cutting device includes a cutting table 1, on the top of which two upright frames 2 arranged opposite to each other are fixed by bolts, a horizontal beam 3 extending left and right is fixed by bolts between the upper ends of the two upright frames 2, and a slide 4 is installed on the horizontal beam 3 for transverse sliding; in order to improve the sliding stability of the slide 4, a mounting hole 5 matching the horizontal beam 3 is provided on the slide 4, and the mounting hole 5 passes through the slide 4 transversely, and convex strips 6 are respectively integrally formed on the top wall and the front and rear side walls of the mounting hole 5, and a guide groove 7 matching the convex strip 6 is provided on the horizontal beam 3, and the guide groove 7 extends left and right along the length direction of the horizontal beam 3.

[0024] The bottom of the slide 4 is bolted with a cutting machine body 8, and a cutting groove 10 is provided on the cutting table 1 for avoiding the blade 9 of the cutting machine body 8. The cutting groove 10 is located directly below the blade 9 of the cutting machine body 8, and the cutting groove 10 extends left and right along the moving direction of the cutting machine body 8. In this embodiment, a backing plate 11 is fixedly installed on the top right side of the cutting table 1 located on the front and rear sides of the crossbeam 3 by bolts, and a fixed seat 12 is fixedly installed on the top of the cutting table 1 located on the right side of the backing plate 11 by bolts, and a cantilever extending to the left is provided at the upper end of the fixed seat 12, and a vertically extending screw 13 is screwed on the cantilever of the fixed seat 12, and a knob is fixedly installed on the upper end of the screw 13, and a pressure plate 14 is rotatably installed on the lower end. Initially, the slide 4 is located at the left end of the beam 3; when cutting, the part of the rock slab to be cut is placed above the cutting groove 10, and one side of the rock slab is close to the support plate 11 to prevent the rock slab from being placed crookedly; then the screw 13 is rotated and the rock slab is pressed tightly by the pressing plate 14 to improve the stability during cutting; finally, the slide 4 is pushed to the right to drive the cutting machine body 8 to move right, and the rock slab can be cut by the cutting machine body 8.

[0025] like Figure 2 and Figure 3 As shown, a vertically extending sliding cavity 15 is provided in the sliding seat 4, and a movable column 16 is vertically slidably installed in the sliding cavity 15. The cross-section of the sliding cavity 15 is circular and matches the movable column 16, so as to improve the sliding stability of the movable column 16; a latch 17 is integrally formed at the upper end of the movable column 16, and the latch 17 is cylindrical and coaxially arranged with the movable column 16, and the outer diameter of the latch 17 is smaller than the outer diameter of the movable column 16, and a through hole 18 is provided at the top of the sliding cavity 15 for the latch 17 to pass through, and the through hole 18 is upwardly connected to the bottom wall of the mounting hole 5, and a pin groove 19 is provided at the bottom of the beam 3 for the latch 17 to be inserted. In order to facilitate locking the cutting machine body 8 at any position of the beam 3, a plurality of pin grooves 19 are provided, and the plurality of pin grooves 19 are evenly spaced along the length direction of the beam 3.

[0026] A spring 20 is provided in the slide cavity 15 for inserting the latch 17 into the pin slot 19. A coaxial positioning column is integrally formed at the lower end of the movable column 16. The upper end of the spring 20 is sleeved on the positioning column and abuts against the lower end of the movable column 16. The lower end of the spring 20 abuts against the bottom wall of the slide cavity 15. When there is no external force, the spring 20 gives the movable column 16 an upward thrust. When the slide 4 moves along the beam 3 and drives the latch 17 to align vertically with one of the pin slots 19, the movable column 16 drives the latch 17 to insert upward into the pin slot 19, thereby limiting the slide 4 from continuing to move along the beam 3, achieving the effect of locking the cutting machine body 8 on the beam 3, and avoiding safety accidents caused by accidentally pushing the cutting machine body 8 to move.

[0027] A mounting cavity 21 is also provided in the slide seat 4 located on the right side of the slide cavity 15. In this embodiment, the slide seat 4 is composed of two front and rear half shells fixed by bolts. The slide cavity 15 and the mounting cavity 21 are both located between the two half shells to facilitate the installation of the internal components of the slide seat 4. A rotating shaft 22 is rotatably installed on the slide seat 4 through a bearing. The axis of the rotating shaft 22 is perpendicular to the length direction of the slide cavity 15, and the axis of the rotating shaft 22 is perpendicular to the length direction of the crossbeam 3. The rotating shaft 22 in this embodiment extends forward and backward; the rotating shaft 22 passes through the mounting cavity 21, and a gear 23 located in the mounting cavity 21 is fixedly installed on the rotating shaft 22. A rack 24 meshing with the gear 23 is integrally formed on the right side of the movable column 16. A through opening 25 for the rack 24 to pass through is provided between the slide cavity 15 and the mounting cavity 21, and the rack 24 can move up and down in the through opening 25. Both ends of the rotating shaft 22 extend to the outside of the slide 4. The two ends of the rotating shaft 22 are respectively fixed with a shift plate 26 located on the outside of the slide 4 by bolts, and a shift lever 27 is welded on the outside of the shift plate 26. By shifting the shift lever 27, the rotating shaft 22 is driven to rotate counterclockwise, and then the rotating shaft 22 drives the rack 24 and the movable column 16 to move downward through the gear 23, and the movable column 16 drives the latch 17 downward to disengage the pin slot 19, and then the staff can push the slide 4 to drive the cutting machine body 8 to move for cutting operations.

[0028] like Figure 2 and Figure 4 As shown, a push-pull handle 28 is rotatably mounted on the rotating shaft 22. The push-pull handle 28 includes two connecting parts 29 symmetrically arranged front and back. A rotating sleeve 30 is welded at one end of the connecting part 29. The rotating sleeve 30 is rotatably sleeved on the rotating shaft 22. Two dial plates 26 are respectively located on the inner sides of the corresponding rotating sleeves 30, and a gap is left between the dial plates 26 and the corresponding rotating sleeves 30 to prevent the rotating sleeves 30 from squeezing the dial plates 26. A holding part 31 is provided between the ends of the two connecting parts 29 away from the rotating shaft 22. The two connecting parts 29 and the holding part 31 are integrally bent and formed. The lever 27 is located on the rotation trajectory of the corresponding connecting part 29, and the lever 27 is located in the counterclockwise direction of the connecting part 29. When the connecting part 29 acts on the lever 27 and causes the latch 17 to disengage from the pin slot 19, the holding part 31 is located obliquely above the left side of the slide seat 4.

[0029] Initially, the slide 4 is located at the left end of the beam 3; when cutting, the staff stands on the left side of the cutting table 1, holds the gripping portion 31 and presses the push-pull handle 28 counterclockwise downward, and then the connecting portion 29 of the push-pull handle 28 presses the lever 27 downward and drives the rotating shaft 22 and the gear 23 to rotate counterclockwise, so that the latch 17 is disengaged from the pin groove 19, and then the staff holds the gripping portion 31 of the push-pull handle 28 and pushes the slide 4 and the cutting machine body 8 to move right to perform the cutting operation. When the latch 17 is disengaged from the pin groove 19, the gripping portion 31 of the push-pull handle 28 remains in a state of being obliquely above the left side of the slide 4, and one end of the gripping portion 31 of the push-pull handle 28 extends toward the staff side, and the staff can more easily push the slide 4 and the cutting machine body 8 to move by holding the gripping portion 31.

[0030] After the cutting operation is completed, the worker holds the gripping portion 31 of the push-pull handle 28 and pulls the slide 4 and the cutting machine body 8 to the left to return to their original positions. When the slide 4 moves to the left end of the beam 3 again, the push-pull handle 28 can be turned clockwise to the right so that the push-pull handle 28 rests on the beam 3. Figure 5 As shown, the gripping portion 31 of the push-pull handle 28 is prevented from extending out of the left side of the cutting table 1 and occupying a large space, thereby facilitating storage.
