Description

Technical Field

[0001] The invention relates to the technical field of concrete processing, in particular to a method for manufacturing a concrete plate containing floating beads. Background Art

[0002] Concrete slabs containing floating beads are a new type of building material. They are made of fly ash, lime, cement, gypsum, slag and other main raw materials, with appropriate amounts of gas generating agents, regulators, bubble stabilizers added. They are made through processes such as batching, mixing, pouring, static stopping, cutting and high-pressure steaming to form a porous concrete product. They are mainly used as building wall materials. The floating beads are a kind of hollow glass microbeads. Concrete slabs containing floating beads have the advantages of light weight, thermal insulation, fire retardancy, sound insulation and noise reduction, high strength, etc. Therefore, they have been widely used in the field of construction. When cutting concrete slabs, the slabs are usually cut separately by horizontal cutting equipment and vertical cutting equipment.

[0003] However, there are the following defects when cutting concrete slabs:

[0004] When cutting concrete slabs, the cutting wire needs to move back and forth, and the reciprocating steel wire leaves wavy cutting marks on the cutting surface during cutting. The wavy cutting marks will make the cutting surface uneven, affecting the surface quality of the concrete slab. At the same time, in order to eliminate the wavy cutting marks, additional processing steps or time may be required, which will reduce production efficiency.

[0005] When cutting concrete slabs, horizontal cutting equipment and vertical cutting equipment cut the slabs separately, and multiple sets of equipment are needed for cutting, and multiple sets of equipment require more space to be placed.

[0006] Therefore, the present invention proposes a method for manufacturing a concrete slab containing floating beads to make up for and improve the deficiencies of the prior art. Summary of the invention

[0052] During the specific work, the concrete slab to be cut is placed on the traction trolley 3, and the traction trolley 3 moves from the left side along the track 2 to the inside of the support frame 4. The traction trolley 3 drives the concrete slab to first pass through the shaping mechanism 9 to scrape the front and rear sides of the concrete slab flat, and then the switching mechanism 8 drives the cutting mechanism 5 to cut the concrete slab in the horizontal and vertical directions respectively.

[0053] See also Figure 4 and Fig.11The cutting mechanism 5 includes a U-shaped moving frame 51 horizontally arranged inside the supporting frame 4, the opening of the U-shaped moving frame 51 faces the left side of the supporting frame 4, and the U-shaped moving frame 51 is symmetrically rotatably connected with rotating rods 52 on the front and rear sides, and each rotating rod 52 is fixedly connected with a plurality of mounting blocks 53 equidistantly outside, and each mounting block 53 is rotatably connected with an articulated seat 54 at the bottom, and the articulated seat 54 penetrates the mounting block 53 front and back, and two steel wires 55 are fixedly connected between two articulated seats 54 corresponding to each other front and back, and a first connecting rod 56 is fixedly connected to one end of the plurality of articulated seats 54 on the same side away from the steel wire 55, and a first sliding groove 57 is opened on the top of the plurality of first connecting rods 56, and a first sliding groove 57 is slidably connected with a first slider 68, and a pushing component 7 is arranged above the U-shaped moving frame 51.

[0054] See also Figure 4 , Figure 8 and Fig.10 The cutting mechanism 5 also includes a first push rod 58 symmetrically arranged at the end away from the first connecting rod 56, the first push rod 58 is fixedly connected to one end of the first sliding block 68, the outside of the rotating rod 52 is symmetrically fixedly connected to a fixed plate 59, one end of the first push rod 58 is fixedly connected to a guide rod 60, the guide rod 60 slides through the bottom of one of the fixed plates 59, and the side of the other fixed plate 59 is fixedly connected to a first hydraulic rod 61, the telescopic section of the first hydraulic rod 61 slides through the fixed plate 59, and the telescopic section of the first hydraulic rod 61 is fixedly connected to the end of the first push rod 58 away from the guide rod 60.

[0055] During specific operation, when the concrete slab is cut horizontally, the switching mechanism 8 drives the cutting mechanism 5 to rotate ninety degrees to the left. At this time, the U-shaped moving frame 51 is in a vertical state, and all the steel wires 55 are distributed above the base 1 from top to bottom, and the two steel wires 55 on the same hinged seat 54 are in the same horizontal plane. The concrete slab is driven by the traction trolley 3 to move along the track 2 to the inside of the support frame 4, and is horizontally cut by the steel wires 55 during the movement of the concrete slab.

[0056] When the concrete slab is cut vertically, first, the horizontally cut concrete slab is moved to the left by the traction trolley 3, and the concrete slab is moved from the inside of the support frame 4 to the outside, and then the cutting mechanism 5 is driven to rotate ninety degrees to the right by the switching mechanism 8. At this time, the U-shaped moving frame 51 is in a horizontal state again, and the U-shaped moving frame 51 drives the steel wire 55 to descend to cut the concrete slab on the traction trolley 3 in the vertical direction. After the steel wire 55 descends to the lowest position, the steel wire 55 rises above the concrete slab, so that the position of the steel wire 55 is higher than the concrete slab, and then the first hydraulic rod 61 drives the first push rod 58 to move horizontally, and the horizontally moving first push rod 58 drives the hinge seat 54 to rotate through the first connecting rod 56, so that the hinge seat 54 drives the two steel wires 55 to rotate ninety degrees. At this time, the two steel wires 55 are in a horizontal state, and the two steel wires 55 are driven to descend again. The two steel wires 55 are in contact with both sides of the cutting surface respectively, and the two sides of the cutting surface are trimmed by the two steel wires 55 to make the cutting surface smoother.

[0057] See also Figure 4 , Figure 5 and Fig.12 The left sides of the two rotating rods 52 are fixedly connected with a second connecting rod 62, and a second sliding groove 63 is opened on the side wall of each second connecting rod 62. A second sliding block 69 is slidably connected in each second sliding groove 63. One end of the two second sliding blocks 69 is fixedly connected with a second push rod 64, and the second push rod 64 is slidably connected to the right side of the U-shaped moving frame 51. The middle part of the second push rod 64 is rotatably connected to the eccentric wheel 66. The right side of the U-shaped moving frame 51 is fixedly connected with a mounting plate 67, and the top of the mounting plate 67 is fixedly connected with a driving motor 65, and the output end of the driving motor 65 is fixedly connected to the eccentric wheel 66.

[0058] During specific operation, when the concrete slab is cut vertically, the driving motor 65 drives the eccentric wheel 66 to rotate, and the eccentric wheel 66 drives the second push rod 64 to move back and forth along the right side of the U-shaped moving frame 51. The reciprocating second push rod 64 drives the two rotating rods 52 to rotate reciprocally synchronously through the second connecting rod 62. The two reciprocating rotating rods 52 drive the two steel wires 55 to reciprocate synchronously, and the reciprocating steel wires 55 cut the concrete slab.

[0059] When the concrete slab is cut in the horizontal direction, the steel wire 55 does not need to move back and forth, and at this time, the driving motor 65 is in a stopped state.

[0060] See also Figure 4 and Fig. 9The pushing assembly 7 includes a U-shaped mounting frame 71 arranged directly above the U-shaped moving frame 51. The U-shaped mounting frame 71 slides symmetrically front and back and penetrates a first sliding rod 72. The bottom of each first sliding rod 72 is fixedly connected to the top of the U-shaped moving frame 51. The top of the U-shaped mounting frame 71 is symmetrically fixedly connected to a second hydraulic rod 73 front and back, and the output end of each second hydraulic rod 73 is fixedly connected to the top of the U-shaped moving frame 51.

[0061] During specific work, when cutting concrete slabs, the U-shaped movable frame 51 is pushed downward by the second hydraulic rod 73. During the downward movement of the U-shaped movable frame 51, the first sliding bar 72 slides downward synchronously along the U-shaped mounting frame 71. The first sliding bar 72 provides support for the U-shaped movable frame 51, thereby enhancing the stability of the downward movement of the U-shaped movable frame 51.

[0062] See also Figure 7 The switching mechanism 8 includes two groups of rollers 82 symmetrically fixedly connected to the inside of the support frame 4 front and back, each group of rollers 82 has four rollers 82, and a support ring 81 is rotatably connected between the four rollers 82. A Japanese-shaped support member 83 is fixedly connected inside each support ring 81, and a fixing rod 84 is fixedly connected to one side of the two support members 83 close to each other. A limiting cross bar 85 is fixedly connected to the top and rear of the support frame 4, and a locking assembly 87 is arranged in the middle of each limiting cross bar 85.

[0063] See also Figure 8 The front and rear sides of the U-shaped mounting frame 71 are fixedly connected to the corresponding fixing rods 84 respectively, and the opening of the U-shaped mounting frame 71 faces the left side of the support frame 4. A cylinder 86 is fixedly connected to the right side of the U-shaped mounting frame 71, and the cylinder 86 has slots 874 symmetrically opened in the front and rear.

[0064] During specific operation, when the concrete slab is cut horizontally, the support ring 81 is driven by an external driving device to rotate ninety degrees to the left, and the support ring 81 rotates along the four rollers 82. The support ring 81 drives the cutting mechanism 5 to rotate ninety degrees synchronously through the support member 83 and the fixing rod 84. At this time, the cylinder 86 on the right side of the U-shaped mounting frame 71 enters into the locking assembly 87 on the limiting cross bar 85 at the top of the support frame 4, and the position of the U-shaped mounting frame 71 is fixed by the locking assembly 87. It should be noted that the external driving device can be a gear set driven by a motor.

[0065] When the concrete slab is cut in the vertical direction, the support ring 81 is driven by an external driving device to rotate ninety degrees to the right, and the cutting mechanism 5 is synchronously rotated ninety degrees to the right. At this time, the cylinder 86 on the right side of the U-shaped mounting frame 71 enters into the locking assembly 87 on the limiting cross bar 85 on the right side of the supporting frame 4, and the position of the U-shaped mounting frame 71 is fixed by the locking assembly 87.

[0066] See also Figure 8The locking assembly 87 includes a groove 871 opened in the middle of the limiting cross bar 85, and each side wall of the limiting cross bar 85 is provided with a receiving groove 872. The receiving groove 872 is connected to the groove 871, and plug rods 873 are symmetrically arranged in the front and back of the receiving groove 872. The two plug rods 873 are horizontally slidably connected to the limiting cross bar 85. One end of the two plug rods 873 is close to each other and extends into the groove 871. A spring 879 is fixedly connected between the end of the two plug rods 873 that is away from each other and the side wall of the receiving groove 872.

[0067] During specific operation, when the position of the U-shaped mounting frame 71 needs to be fixed, the cylinder 86 on the right side of the U-shaped mounting frame 71 enters the groove 871, and the cylinder 86 first pushes the two insertion rods 873 away from each other. Then, when the cylinder 86 completely enters the groove 871, the two insertion rods 873 are pushed closer to each other by the elastic force of the spring 879, and the two insertion rods 873 approaching each other respectively enter the two slots 874 on the side of the cylinder 86, fixing the cylinder 86 in the groove 871 of the limiting cross bar 85, fixing the position of the U-shaped mounting frame 71, thereby realizing the fixation of the position of the cutting mechanism 5.

[0068] See also Figure 8 and Fig. 9 A lever 875 is fixedly connected to the bottom of each insertion rod 873, an elliptical extrusion block 876 is rotatably connected inside the accommodating groove 872, and the extrusion block 876 is located in the area between the two levers 875, a cover plate 877 is fixedly connected to the outer opening of the accommodating groove 872 by bolts, a servo motor 878 is fixedly connected to the outside of the cover plate 877, and the output end of the servo motor 878 is fixedly connected to the extrusion block 876.

[0069] During specific operation, when it is necessary to rotate the cutting mechanism 5, it is first necessary to release the position fixation of the U-shaped mounting frame 71, and drive the extrusion block 876 to rotate through the servo motor 878. When the extrusion block 876 rotates, it pushes the two levers 875 to respectively drive the two insertion rods 873 away from each other. The insertion rods 873 that are away from each other are disengaged from the slots 874, and the U-shaped mounting frame 71 can rotate. After that, the cutting mechanism 5 is driven to rotate through the switching mechanism 8.

[0070] See also Figure 7 The shaping mechanism 9 includes a second slide bar 91 horizontally fixedly connected to the left side of the support frame 4, and a moving block 93 is symmetrically slidably sleeved on the outside of the second slide bar 91. A scraper 94 is fixedly connected to the bottom of each moving block 93. The two moving blocks 93 are also threadedly connected to a bidirectional screw rod 92. Both ends of the bidirectional screw rod 92 are rotatably connected to the left side of the support frame 4. One end of the bidirectional screw rod 92 passes through the support frame 4 and is fixedly connected to a hand wheel 95.

[0071] During specific operation, when the traction trolley 3 drives the concrete slab to move along the track 2, the front and rear sides of the concrete slab are in contact with the two scrapers 94, and the front and rear sides of the concrete slab are shaped by the scrapers 94, and the bidirectional screw 92 is driven to rotate by rotating the handwheel 95, thereby driving the two moving blocks 93 to move away from or closer to each other. During the movement, the two moving blocks 93 synchronously drive the two scrapers 94 to move away from or closer to each other, so that the two scrapers 94 are tightly attached to the front and rear sides of the concrete slab.

[0072] Working process: First, the concrete slab is cut horizontally, and the cutting mechanism 5 is driven to rotate ninety degrees to the left by the switching mechanism 8. At this time, the cylinder 86 on the right side of the U-shaped mounting frame 71 enters into the locking assembly 87 of the limiting cross bar 85 on the top of the support frame 4, and the position of the U-shaped mounting frame 71 is fixed by the locking assembly 87. After that, the spacing of the scraper 94 of the shaping mechanism 9 is adjusted. When the concrete slab is driven to move to the right along the track 2 by the traction trolley 3, the front and rear sides of the concrete slab are in contact with the two scraper 94, and the front and rear sides of the concrete slab are shaped by the scraper 94. Then, the traction trolley 3 continues to drive the concrete slab to move to the right along the track 2, and the concrete slab is horizontally cut by the steel wire 55.

[0073] After cutting in the horizontal direction, the traction trolley 3 drives the concrete slab to the left along the track 2 to the left side of the support frame 4, and then drives the cutting mechanism 5 to rotate right by ninety degrees through the switching mechanism 8. At this time, the cylinder 86 on the right side of the U-shaped mounting frame 71 enters into the locking assembly 87 of the limiting cross bar 85 on the right side of the support frame 4. The concrete slab is driven to move right along the track 2 to the inside of the support frame 4 by the traction trolley 3, and the U-shaped moving frame 51 descends to cut the concrete slab in the vertical direction. After cutting, the two steel wires 55 are rotated ninety degrees, and the U-shaped moving frame 51 rises again to shape the cutting surface through the two rotated steel wires 55.
