Description

Technical Field

[0001] The invention relates to the technical field of precast concrete slab transportation, and in particular to a precast concrete slab transportation device and a use method thereof. Background Art

[0002] In the field of construction engineering, precast concrete panels are widely used. With the acceleration of urbanization and the continuous expansion of construction scale, higher requirements are placed on the production and transportation efficiency of precast concrete panels.

[0003] Traditional transportation methods for precast concrete panels often rely on simple flatbed trailers or forklifts. During transportation, due to the lack of effective fixing and protection measures, the precast panels are prone to displacement, shaking or even sliding during transportation, which will not only damage the precast panels, affecting their quality and subsequent performance, but may also cause serious safety accidents and endanger the safety of other vehicles and pedestrians on the road. Moreover, flatbed trailers have poor adaptability to precast panels of different sizes and shapes, and the loading method and fixing means need to be adjusted frequently. At the same time, forklifts have poor stability during transportation and high costs.

[0011] A method for using a precast concrete slab transport device comprises the following steps:

[0012] S1. First, the concrete precast panels are placed on the surface of the conveyor belt. The electric machine tool drives the conveyor belt to transport the concrete precast panels intermittently. Then, the electric machine tool drives the half gear to rotate continuously. When the half gear rotates, it drives the small gear to rotate intermittently. The operation time of the conveyor belt is staggered with the rotation time of the small gear. When the small gear rotates, it drives the roller to rotate. When the roller rotates, it drives the extension rod to rotate. When the extension rod rotates, it drives the pulley to rotate. When the pulley rotates, it drives the gear 1 to rotate through the transmission belt. When the gear 1 rotates, it drives the meshing gear 2 to rotate. When the gear 2 rotates, it drives the gear 3 to rotate. When the gear 3 rotates, it drives the half gear 2 at the other end to rotate half a circle clockwise. When the half gear 2 rotates, it drives the double-sided rack to slide upward inside the slide groove. When the half gear 2 separates from the double-sided rack, the half gear 1 will mesh with the double-sided rack, driving the double-sided rack to slide downward inside the slide groove, realizing up and down reciprocating motion;

[0013] When the L-shaped rack moves to the inclined groove, the continuously rising connecting rod rotates on the surface of the double-sided rack, driving the concrete precast panel to a vertical state, and at the same time, the sliding rod enters the interior of the arc groove and the interior of the spiral groove, and then the sliding rod drives the transport frame to rotate ninety degrees inside the U-shaped frame through the spiral groove, so that the side thin edge of the concrete precast panel faces the staff, and the friction of the concrete precast panel is reduced by the pulley while being pulled out, which makes it easier to pull out, and the U-shaped frame and the transport frame are in a cross state;

[0014] S3, when the gear rotates, it drives the half gear at the other end to rotate half a circle clockwise, and when the half gear rotates, it drives the double-sided rack to slide downward inside the slide slot to drive the U-shaped frame and the transport frame to reset, and the cycle is repeated to achieve continuous transportation and handling;

[0015] S4. When the concrete precast slab is on the conveyor belt, the extension rod rotates and drives the connecting rod 1 to rotate. When the connecting rod 1 rotates, it drives the connecting rod 2 to pull or push the slide plate to slide back and forth inside the fixed slide groove. When the slide plate slides, it squeezes the L-shaped support rod through the inclined groove 1 and reciprocates back and forth inside the limiting slide groove. When the L-shaped support rod moves forward, the T-shaped slide groove and the sorting rod move between the two concrete precast slabs at the same time. At the same time, when the sorting rod is blocked by the side of the electric machine, the L-shaped support rod will slide in the T-shaped slide groove, drive the inclined groove plate to slide at the same time, and squeeze the sliding rod. The sliding rod drives the sorting rod to slide inward through the inclined groove plate, so as to regularize the concrete precast slab so that it can enter the interior of the transport frame in sequence. At the same time, when the sorting rod contacts the concrete precast slab, the concrete precast slab is polished by the polishing sheet, and the burrs and raised areas of the flare are polished.

[0016] In the present invention, the connecting rod rotates on the surface of the double-sided rack to drive the concrete precast panel to a vertical state, the sliding rod enters the interior of the arc-shaped sliding groove and the interior of the spiral groove, and the sliding rod drives the transport frame to rotate ninety degrees inside the U-shaped frame through the spiral groove, so that the side thin edge of the concrete precast panel faces the staff, and the staff can easily pull out the concrete precast panel and load it into the truck.

[0017] In the present invention, when the precast concrete panel is pulled out, the pulley can reduce the friction of the precast concrete panel, making it easier to pull out, and the U-shaped frame and the transport frame are in a cross state, which can prevent the precast concrete panel from falling from the side.

[0018] In the present invention, the arranging rod is driven to slide inward by the inclined groove plate, so that the concrete precast panels are arranged in order so that they can enter the interior of the transport frame in sequence. At the same time, when the arranging rod contacts the concrete precast panels, the concrete precast panels are polished by the polishing sheet, and the burrs and raised areas of the handles are polished to prevent scratches on the staff, thereby further improving the transportation time and efficiency.

Then the motor machine 1 drives the half gear 31 to rotate continuously. When the half gear 31 rotates, it drives the small gear 33 to rotate intermittently. The operation time of the conveyor belt 2 is staggered with the rotation time of the small gear 33. When the small gear 33 rotates, it drives the roller 32 to rotate.

At the same time, the U-shaped frame 52 is limited by the L-shaped rod 55 to move horizontally upward. When the transport frame 53 moves upward, the L-shaped rod 58 is driven to move upward at the same time. When the L-shaped rod 58 moves upward, the inclined surface of the inclined sliding groove 59 causes the L-shaped rod 58 to slide in the arc groove 511, driving the baffle 56 to rotate to block the bottom of the transport frame 53. When the L-shaped rod 55 moves to the inclined groove 49, the holding plate 56 is The connecting rod 54 that continues to rise rotates on the surface of the double-sided rack 46, driving the concrete precast panel to a vertical state, and at the same time, the sliding rod 510 enters the interior of the arc-shaped sliding groove 512 and the interior of the spiral groove 513, and then the sliding rod 510 drives the transport frame 53 to rotate ninety degrees inside the U-shaped frame 52 through the spiral groove 513, so that the thin side edge of the concrete precast panel faces the staff, and the pulley 57 reduces the friction of the concrete precast panel while pulling it out, making it easier to pull it out, and the U-shaped frame 52 and the transport frame 53 are in a cross state;

[0046] S4. When the concrete precast slab is on the conveyor belt 2, the extension rod 34 rotates to drive the connecting rod 1 62 to rotate. When the connecting rod 1 62 rotates, it drives the connecting rod 2 63 to pull or push the slide plate 64 to slide back and forth inside the fixed slide groove 61. When the slide plate 64 slides, it squeezes the L-shaped support rod 67 through the inclined groove 1 65 to reciprocate back and forth inside the limiting slide groove 66. When the L-shaped support rod 67 moves forward, the T-shaped slide groove 68 and the sorting rod 611 move between the two concrete precast slabs at the same time. When the rod 611 is blocked by the side of the electric machine tool 1, the L-shaped support rod 67 will slide in the T-shaped slide groove 68, driving the inclined groove plate 69 to slide at the same time and squeezing the sliding rod 612.

5. A method for using a precast concrete slab transport device, using the precast concrete slab transport device according to claim 4, characterized in that: The steps include: S1. First, a precast concrete panel is placed on the surface of a conveyor belt (2). The electric machine tool (1) drives the conveyor belt (2) to intermittently transport the precast concrete panel. Then, the electric machine tool (1) drives the half gear (31) to rotate continuously. When the half gear (31) rotates, it drives the pinion gear (33) to rotate intermittently. The operation time of the conveyor belt (2) is staggered with the rotation time of the pinion gear (33). When the pinion gear (33) rotates, it drives the roller (32) to rotate. When the roller (32) rotates, it drives the extension rod (34) to rotate. When the extension rod (34) rotates, it drives the pulley (35) to rotate. When the pulley (35) rotates, it drives the transmission belt (3 6) drives gear 1 (42) to rotate, and when gear 1 (42) rotates, it drives the meshing gear 2 (43) to rotate, and when gear 2 (43) rotates, it drives gear 3 (44) to rotate, and when gear 3 (44) rotates, it drives the other end of half gear 2 (48) to rotate half a circle clockwise, and when half gear 2 (48) rotates, it drives the double-sided rack (46) to slide upward inside the slide groove (45), and when half gear 2 (48) and the double-sided rack (46) separate, half gear 1 (47) will mesh with the double-sided rack (46), driving the double-sided rack (46) to slide downward inside the slide groove (45), realizing up and down reciprocating motion; S2. When the double-sided rack (46) moves upward, the U-shaped frame (52) and the transport frame (53) are driven to move upward through the connecting rod (54). At the same time, the U-shaped frame (52) is limited by the L-shaped rod (55) so that it moves upward horizontally. When the transport frame (53) moves upward, the L-shaped rod (58) is driven to move upward at the same time. When the L-shaped rod (58) moves upward, the inclined surface of the inclined sliding groove (59) causes the L-shaped rod (58) to slide in the arc groove (511), driving the baffle (56) to rotate and block the bottom of the transport frame (53). When the L-shaped rod (55) moves to the inclined groove (49), When the connecting rod (54) is continuously raised, it rotates on the surface of the double-sided rack (46), driving the concrete precast panel to a vertical state. At the same time, the sliding rod (510) enters the interior of the arc-shaped sliding groove (512) and the interior of the spiral groove (513). Then, the sliding rod (510) drives the transport frame (53) to rotate ninety degrees inside the U-shaped frame (52) through the spiral groove (513), so that the thin side edge of the concrete precast panel faces the staff. When the concrete precast panel is pulled out, the friction force of the concrete precast panel is reduced by the pulley (57), making it easier to pull out. The U-shaped frame (52) and the transport frame (53) are in a cross state. S3, when the gear 1 (42) rotates, the half gear 1 (47) at the other end rotates half a circle clockwise, and when the half gear 1 (47) rotates, the double-sided rack (46) slides downward inside the slide groove (45) to drive the U-shaped frame (52) and the transport frame (53) to reset, and the cycle is repeated to achieve continuous transportation and handling; S4. When the concrete precast panel is on the conveyor belt (2), the extension rod (34) rotates to drive the connecting rod 1 (62) to rotate. When the connecting rod 1 (62) rotates, it drives the connecting rod 2 (63) to pull or push the slide plate (64) to slide back and forth inside the fixed slide groove (61). When the slide plate (64) slides, it squeezes the L-shaped support rod (67) through the inclined groove (65) to reciprocate back and forth inside the limiting slide groove (66). When the L-shaped support rod (67) moves forward, the T-shaped slide groove (68) and the sorting rod (611) move between the two concrete precast panels at the same time. When the arranging rod (611) is blocked by the side of the electric machine tool (1), the L-shaped support rod (67) will slide in the T-shaped slide groove (68), driving the inclined groove plate (69) to slide at the same time and squeeze the sliding rod (612). The sliding rod (612) drives the arranging rod (611) to slide inward through the inclined groove plate (69), so as to regularize the precast concrete panels and make them enter the interior of the transport frame (53) in sequence. At the same time, when the arranging rod (611) contacts the precast concrete panels, the precast concrete panels are polished by the polishing sheet (613), and the burrs and the raised areas of the handles are polished.
