[0013] The beneficial effects of the supporting gripper for marble processing of the present invention are as follows:

[0014] (1) The present invention forms a stable clamping system by arranging the intermediate pressure frame, clamping plate 1, clamping plate 2, connecting plate, connecting rod and other components in the supporting and grasping mechanism to cooperate with each other; when the main frame presses down the marble slab, the intermediate pressure frame is driven by the marble limit and the downward movement of the main frame, and moves relative to it inside the main frame. The intermediate pressure frame causes the four gears 2 to rotate axially through the tooth groove structure, and drives the ratchet wheel to rotate. During the descending process, the one-way locking of the ratchet wheel and the pawl ensures that the clamping structures such as clamping plate 1 and clamping plate 2 will not loosen after clamping the marble slab, thereby realizing a fast clamping operation and ensuring the stability of the clamping.

[0015] (2) During the use of the present invention, the bottom frame, rotating drum, transmission rod, bracket and other structures contact the ground during the descent of the supporting and grasping mechanism; under the ground limit, the length of the vertical frame and the bottom frame is shortened, and the spring is compressed; at the same time, the rotating drum and the transmission rod are rotated through the gear transmission during the sliding of the clamping plate, and the transmission rod drives the bracket to rotate through the torsion spring; but the bracket contacts the rear surface of the marble during the rotation process, so it cannot rotate, and the torsion spring is twisted to accumulate force; when the supporting and grasping mechanism clamps and fixes the marble slab and lifts it up, the spring pushes the bottom frame and the bracket to move downward, and the bracket is no longer limited by the rear surface of the marble after moving, and the torsion spring releases its elastic potential energy to allow the bracket to continue to rotate, and at this time the bracket rotates to the bottom of the marble to support the bottom of the marble slab; the bottom supporting structure effectively prevents the marble slab from accidentally falling during the transportation process, further improving the safety of transportation;

[0016] (3) The operation process of the present invention is relatively simple. The supporting and grasping mechanism is moved to the top of the marble slab by the driving mechanism, and then the hydraulic rod is extended to lower the supporting and grasping mechanism. After the top of the marble slab enters the main frame, the automatic clamping is achieved under the interaction of various components. After the grasping is completed, the marble slab is moved to the sleepers in the carriage by the driving mechanism. When placing the marble slab, the staff only needs to move the bracket, and then control the extension of the electric push rod to release the lock of the clamping structure, and complete the clamping and placement of the marble slab. The simple and efficient operation method greatly improves work efficiency and reduces the complexity of manual operation. BRIEF DESCRIPTION OF THE DRAWINGS

Two adjacent slides 24 are fixed with a clamp 26, and one end of the slide 24 located inside the slide 23 is connected to the medium-pressure frame 17 with a connecting rod 25 for rotation. The lower surface of the main frame 15 is fixed There are two vertical frames 27, and a rotating drum 28 is rotatably connected inside the vertical frame 27. The two slideways 20 located at the rear are each provided with an inner groove 29. The top of the rotating drum 28 is located inside the inner groove 29 and is fixed with a gear 30. A bottom groove 31 is provided at the bottom of the vertical frame 27, and a bottom frame 32 is slidably connected inside the bottom groove 31. A spring 33 is provided at the bottom end of the rotating drum 28 and the top of the bottom frame 32. A transmission rod 34 is penetrated inside the spring 33. The top of the transmission rod 34 is located inside the rotating drum 28 and is slidably connected to the inside of the rotating drum 28. The bottom end of the transmission rod 34 penetrates into the bottom frame 32 and is rotatably connected with a bracket 35. A torsion spring 36 is fixed to the upper surface of the bracket 35 and the outer surface of the transmission rod 34. Tooth grooves are provided on the left and right sides of the clamping plate 21 located at the rear, and the tooth grooves located at the clamping plate 21 are meshed and connected with the two gears 30.

[0035] When the middle pressure frame 17 moves relatively and the clamping plate 21 slides through the connecting plate 22, the rear clamping plate 21 rotates the two gears 30 through the tooth groove structure on both sides;

[0036] The left and right sides of the side groove 18 are both rotatably connected with gear 2 37, and a ratchet 38 is coaxially fixed on one side of the gear 2 37 away from the inner wall of the side groove 18. A rotating rod 39 is rotatably connected to the inside of the side groove 18. Two pawls 40 are fixed on the outer surface of the rotating rod 39. The pawls 40 are engaged with adjacent ratchets 38. Two torsion springs 2 41 are provided on the outer surface of the rotating rod 39 and the inner wall of the side groove 18. The right ends of the two rotating rods 39 both penetrate to the right side of the main frame 15 and are fixed with sleeves 42. A sliding rod 43 is slidably connected inside the sleeve 42. An electric push rod 44 is fixed on the upper right side of the main frame 15. A lifting frame 45 is provided below the bottom end of the telescopic rod of the electric push rod 44. Two movable grooves 46 are provided at the front and rear ends of the lifting frame 45. A movable rod 47 is movably connected inside the groove 46, and the tops of the two slide bars 43 are fixedly connected to the two movable rods 47 respectively. Tooth grooves are provided on the front and rear surfaces of the intermediate pressure frame 17, and the tooth grooves located at the intermediate pressure frame 17 are meshed and connected with four gears 2 37. When the main frame 15 presses down the marble slab, the intermediate pressure frame 17 is driven by the marble limit and the downward movement of the main frame 15, so as to move relative to it inside the main frame 15, and the four gears 2 37 are axially rotated through the tooth groove structure, and the ratchet 38 is driven to rotate. During the descent of the intermediate pressure frame 17, the one-way locking of the ratchet 38 and the pawl 40 is used, so that the clamping structures such as the clamping plate 1 21 and the clamping plate 2 26 will not loosen after clamping the marble slab, thereby ensuring the stability of the downward rapid clamping;

[0037] After the marble slab is placed at the sleeper 5 in the carriage 1, the staff places a partition between the marbles, that is, when it is necessary to release the clamping and place the marble slab, the staff controls the electric push rod 44 to extend, pushes the lifting frame 45 downward, and the lifting frame 45 drives the slide bar 43 to move through the movable groove 46 and the movable rod 47, and rotates the rotating rod 39 through the sleeve 42, so that the pawl 40 rotates to release the limit on the ratchet 38, thereby releasing the locking of the clamping structure such as the intermediate pressure frame 17, the clamping plate 1 21, and the clamping plate 2 26. At this time, the staff moves the bracket 35 and controls the hydraulic rod 12 to contract and lift the holding and grasping mechanism 3, that is, the clamping and placement operation of the marble slab is completed;

[0038] When working, the motor 2 13 in the traveling mechanism 2 runs, so that the screw 2 14 rotates, so that the frame 6 drives the transverse frame 9, the longitudinal frame 10, the supporting and grasping mechanism 3 and other structures to move along the fixed rail 4 and are displayed from the right opening of the carriage 1. Then, when the motor 1 7 runs, the screw 1 8 rotates, and the transverse frame 9, the longitudinal frame 10, and the supporting and grasping mechanism 3 move horizontally left and right along the inside of the frame 6 to adjust the position. At the same time, when the electric running wheel 11 runs, the longitudinal frame 10 drives the supporting and grasping mechanism 3 to move longitudinally forward and backward, so that the supporting and grasping mechanism 3 is located above the marble slab;

[0039] After being in place, the hydraulic rod 12 is extended to make the supporting and grasping mechanism 3 descend. When the supporting and grasping mechanism 3 is in the middle, the top of the marble slab enters the main frame 15, and the interaction causes the intermediate pressure frame 17 and the main frame 15 to move relative to each other, so that the clamping plate 1 21 is pulled by the connecting plate 22 to clamp the marble slab front and back, and at the same time, the slide 24 and the clamping plate 2 26 are pulled by the connecting rod 25 to clamp the front and back sides of the marble slab. At the same time, the bottom frame 32 structure located at the bottom contacts the ground during the descending process of the supporting and grasping mechanism 3, so that the length of the vertical frame 27 and the bottom frame 32 is shortened under the ground limit, the spring 33 is compressed, and the vertical frame 27 and the bottom frame 32 are .... The transmission through gear 30 will cause the rotating drum 28 and the transmission rod 34 to rotate, and the transmission rod 34 drives the bracket 35 to rotate through the torsion spring 36. However, the bracket 35 contacts the rear surface of the marble during rotation and cannot rotate. The torsion spring 36 twists and stores force. When the supporting and grasping mechanism 3 clamps the fixed marble slab and lifts it up, the spring 33 pushes the base frame 32 and the bracket 35 to move downward. After the bracket 35 moves, it is no longer limited by the rear surface of the marble. The torsion spring 36 releases its elastic potential energy to allow the bracket 35 to continue to rotate. At this time, the bracket 35 rotates to the bottom of the marble to support the bottom of the marble slab to prevent it from falling accidentally.

[0040] Reference Figure 2 , Fig.10 The intermediate pressure frame 17 is a U-shaped structure, and the carriage 1 is a rectangular parallelepiped structure with an opening on the right and a hollow interior.

[0041] Reference Fig. 9 The rotating drum 28 is a hollow cylinder with a rectangular interior. The transmission rod 34 is composed of two rod bodies with different geometric shapes from top to bottom. The upper part is a rectangular rod body part, and the lower part is a cylindrical part. The transmission rod 34 is slidably connected to the inside of the rotating drum 28, so that when the rotating drum 28 descends with the vertical frame 27, the transmission rod 34 and the bracket 35 will not be able to move downward due to the ground limit and compress the spring 33. At this time, the rotating drum 28 will slide outside the upper rectangular rod section of the transmission rod 34 and maintain the axial synchronous rotation function of the rotating drum 28 and the transmission rod 34.

[0042] Reference Figure 7-12 The lower surface of the middle pressure frame 17, the opposite sides of the two clamping plates 26, the opposite sides of the two clamping plates 1 21, and the upper surfaces of the two brackets 35 are all provided with rubber layers, which can protect the marble slabs when clamping them and improve the resistance and stable clamping effect.

[0043] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
