The drive wheel 41 below the opening of the mobile frame 3 is preferably slightly below the bottom surface of the power roller 11 of the conveyor 1. Referring again to fig. 5, one of the driving wheels 41 is a tensioning wheel 41-1, and the tensioning wheel 41-1 is connected to a sliding seat 43, and the sliding seat 43 slides in parallel with respect to the moving frame 3. The movable frame 3 is also fixed with a tensioning cylinder 44, the tensioning cylinder 44 is an actuating element such as an oil cylinder or an electric push rod with a telescopic rod in the prior art, the telescopic rod of the tensioning cylinder 44 is used for fixing a sliding seat 43, the sliding seat 43 and the tensioning wheel 41-1 are driven to move by extending out of the telescopic rod of the tensioning cylinder 44, so that the distance between the tensioning wheel 41-1 and the adjacent driving wheel 41 is enlarged, the tensioning force of the cutting rope 4 is improved, and the whole cutting rope 4 is ensured to be properly tensioned.

Further, a supporting rod 21 is fixed at the upper end and the lower end of the portal frame 2, sliding rails 32 are fixed at the upper surface and the lower surface of the supporting rod 21, a plurality of groups of moving wheels 31 are arranged at the upper end and the lower end of the moving frame 3, each group is provided with an upper moving wheel 31 and a lower moving wheel 31, and the upper moving wheels 31 and the lower moving wheels 31 are respectively and adaptively clamped on the upper sliding rail 32 and the lower sliding rail 32 of the same supporting rod 21. Similarly, two sets of moving wheels 31 are disposed on two opposite sides of the back of the sliding seat 43, and the upper and lower moving wheels 31 of the two sets of moving wheels 31 in the sliding seat 43 are respectively engaged with the upper and lower sliding rails 32 of the supporting rod 21, so as to limit the sliding seat 43 to slide along the sliding rails 32 relative to the moving frame 3.
Referring to fig. 5 again, a first support 34 is fixed on the moving frame 3, a rotatable first screw 33 is connected to the gantry 2, and two ends of the first screw 33 are respectively connected to two bearing blocks (not identified in the drawing) fixed on the gantry 2, so as to limit the first screw 33 to rotate only about its axis. The first screw 33 also passes through the first support 34 helically, while the moving motor 35 is fixed to the gantry 2. When the movable frame 3 works, the movable motor 35 drives the first screw rod 33 to rotate, and the movable frame 3 can be driven to horizontally move relative to the conveyor 1 in the portal frame 2.
As shown in fig. 4, the limiting device includes a lifting seat 51, a left limiting box 52 and a right limiting box 53. Wherein, left limit box 52 and right limit box 53 are the box body that one side formed open, all set up spacing area 54 in left limit box 52 and the right limit box 53, and the both ends in left limit box 52 and the right limit box 53 all set up rotatable gyro wheel 55. In the left limit box 52 and the right limit box 53, the limit belt 54 bypasses the two rollers 55, so that the limit belt 54 in the left limit box 52 and the limit belt 54 in the right limit box 53 can operate, and one side of the limit belt 54 is exposed out of the opening. Further, both sides of the ring surface of the roller 55 are provided with raised limiting surfaces 551, and the part of the limiting belt 54 bypassing the roller 55 is limited between the two limiting surfaces 551, so that the limitation of the limiting belt 54 is formed, and the limiting belt 54 is prevented from deviating from the roller 55.
The right limit box 53 is fixed on the lifting seat 51, and the lifting seat 51 is vertically moved or fixed at the opening of the movable frame 3. The left limit box 52 is arranged on one side of the right limit box 53 to swing, and the left limit box 52 drives the left limit box 52 to swing relative to the right limit box 53 through the elastic mechanism, so that the limit belt 54 of the left limit box 52 and the limit belt 54 of the right limit box 53 block the two sides of the sawing section 4-1 of the cutting rope 4. The structure can block the two sides of the upper end of the sawing section 4-1 by using the limiting belts 54, when the movable frame 3 moves, the two limiting belts 54 can push or pull the sawing section 4-1 to move, and meanwhile, the limiting belts 54 can rotate around the rollers 55, so that the limiting belts 54 can also rotate along with the running of the cutting rope 4, and the friction force of the limiting belts is reduced. Further, referring to fig. 9 again, protruding limiting portions 541 are disposed on two sides of the annular surface of the limiting belt 54, when the left limiting box 52 moves to the inside of the limiting belt 54 and the limiting belt 54 of the right limiting box 53 to block two sides of the sawing section 4-1, the sawing section 4-1 is embedded between the limiting portions 541, so as to block two sides of the sawing section 4-1 between the left limiting box 52 and the right limiting box 53, and prevent the sawing section 4-1 from being skewed to the two sides.
Referring to fig. 6 again, a mounting seat 57 is fixed on one surface of the lifting seat 51 facing away from the right limiting box 53, bottom surfaces of the two guide posts 56 are all screwed with fixing bolts 561, studs of the two fixing bolts 561 pass through the mounting seat 57, and bolts of the two fixing bolts 561 are respectively screwed with the two guide posts 56, so that the guide posts 56 and the lifting seat 51 are fixed. When the stone to be sawed is close to the upper part of the opening of the movable frame 3, the limiting device and the elastic mechanism can be integrally dismounted from the movable frame 3 by dismounting the two fixing bolts 561, so that the sawing section 4-1 of the opening part of the movable frame 3 is increased in length, and the movable frame is suitable for processing stone with higher thickness.
The structure for limiting the vertical movement of the lifting seat 51 may be as shown in fig. 5 and 10, where the lifting seat 51 fixes two guide posts 56, the two guide posts 56 extend vertically upward, and the moving frame 3 fixes two guide sleeves (not shown) therein, the guide sleeves may be linear bearing seats, and the two guide posts 56 respectively fit through the two guide sleeves, so as to limit the two guide posts 56 to respectively move vertically relative to the two guide sleeves, thereby limiting the lifting seat 51 to move vertically relative to the moving frame 3. The structure of limiting the movement of the lifting seat 51 and fixing the same may be realized by a second support 58 and a second screw rod 59 of the limiting device, specifically, the second support 58 is fixed at the upper ends of the two guide posts 56, which corresponds to the second support 58 being fixed above the lifting seat 51, the second screw rod 59 penetrates the moving frame 3 vertically and then passes through the second support 58 in a spiral manner, and the lifting motor 510 is also fixed above the moving frame 3, and the upper end of the second screw rod 59 is fixed to the output end of the lifting motor 510. When the lifting motor 510 works, the second screw rod 59 is driven to rotate, so that the second support 58 and the lifting seat 51 can be driven to vertically move to a specified height, and the lifting seat 51 can be fixed by stopping rotation. When the device works specifically, the lifting seat 51 is lowered to be close to the top of the stone material, so that the length from the lower end of the sawing section 4-1 to the limited position of the upper end is shortened, the limiting device can pull the upper end of the stone material cutting part of the sawing section 4-1 to push or push the sawing section 4-1 to provide enough traction force to drive the sawing section 4-1 to stably move forwards, the sawing section 4-1 is prevented from being inclined, the sawing section 4-1 is ensured to be always vertical in the same plane, and the overlong cutting rope 4 is prevented from being deviated to incline in the cutting process, so that the stone material cannot be completely cut.
As shown in fig. 10 and 11, the take-up mechanism includes a pull rod 61, a connector 62, and a take-up screw 63. The lifting seat 51 is pivoted with the first connecting rod 64 and the second connecting rod 65 in sequence, one ends of the first connecting rod 64 and the second connecting rod 65 far away from the lifting seat 51 are pivoted with the pull rod 61, the left limit box 52 and the first connecting rod 64 are pivoted between the pull rod 61 and the right limit box 53, the first connecting rod 64 and the second connecting rod 65 can be driven to swing by pulling the pull rod 61 in the structure, and meanwhile the right limit box 53 is driven to swing relative to the left limit box 52.
As shown in fig. 4, the connecting piece 62 is provided with a movable hole 621 and a connecting hole 622 on two mutually perpendicular sides, and the movable hole of the connecting piece 62 is sleeved outside the pull rod 61, so that the pull rod 61 can move telescopically relative to the connecting piece 62. With continued reference to fig. 10 and 11, the surface of the lifting base 51 is fixedly provided with a threaded base 66, the threaded base 66 is provided with a threaded hole therethrough, the elastic screw 63 is threaded through the threaded hole and then through the connection hole 622 of the connection member 62, and the elastic screw 63 is threaded through the end portion of the connection hole 622 to fix the blocking member 631, and the diameter of the blocking member 631 is larger than the diameter of the connection hole 622. In operation, the forward rotation elastic screw 63 can pull the connecting piece 62 to move towards the right limit box 53 through the blocking piece 631, so as to drive the pull rod 61 to move towards the right limit box 53, thereby enabling the left limit box 52 to swing to the limit belt 54 inside and the limit belt 54 of the right limit box 53 to block the two sides of the upper end of the sawing section 4-1. When the elastic screw 63 is reversed, the connecting piece 62 can be pushed to be far away from the right limit box 53, so that the pull rod 61 is driven to be far away from the right limit box 53, and the gap between the limit belt 54 in the left limit box 52 and the limit belt 54 of the right limit box 53 is enlarged, so that the cutting rope 4 can be conveniently taken out from between the two limit belts 54, and the installation and the replacement are convenient.
In summary, in the operation of the present invention, the lifting motor 510 is controlled to drive the second screw rod 59 to rotate, so as to drive the lifting seat 51 to move vertically to approach the top of the stone on the conveyor 1, so as to shorten the length from the portion limited by the driving wheel 41 to the portion limited by the left limit box 52 and the limit belt 54 of the right limit box 53 at the lower end of the sawing section 4-1 to the portion limited by the limit belt 54 of the left limit box 53, so that when the moving frame 3 drives the cutting rope 4 to move relative to the conveyor 1, the right limit box 53 or the limit belt 54 of the left limit box 52 on the stone can drive the sawing section 4-1 to move towards the stone on the conveyor 1, which is equivalent to that the limit belt 54 of the right limit box 53 or the left limit box 52 pulls the sawing section 4-1 to move forward at a position close to the upper side of the stone, so that the limited position of the sawing section 4-1 is not guaranteed to move forward when the sawing section 4-1 is pulled by the stone, and thus the sawing section 4-1 is prevented from being blocked to be tilted in a state in a cutting process, so that the stone is ensured to cut stably.
The foregoing is merely illustrative of specific embodiments of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modification of the present invention by using the design concept shall fall within the scope of the present invention.
