Description

Technical Field

[0001] The invention relates to the technical field of transportation equipment, in particular to a prefabricated floor slab transportation equipment. Background Art

[0002] Prefabricated components refer to building components with specific shapes, sizes and functions that are pre-fabricated in factories or on-site, and then transported to the construction site for assembly to form a complete building or structure, including prefabricated beams, prefabricated columns, prefabricated floor slabs, prefabricated stairs, etc. When transporting prefabricated floor slabs, a kind of transportation equipment is often used to transport the floor slabs to the designated location.

[0003] When transporting prefabricated floor slabs, traditional transportation equipment usually uses a forklift to place multiple prefabricated floor slabs flat on a cart, and then uses the cart to transport the floor slabs to the interior of the building. Due to the large size of the forklift, it is not convenient to enter the indoor space of the building. When unloading the floor slabs, multiple workers are required to assist in lifting the floor slabs. However, due to the large weight of the prefabricated floor slabs, it is not convenient for workers to carry them. The operation process is cumbersome and the transportation efficiency is low.

[0004] When transporting prefabricated floor slabs, multiple floor slabs are usually placed flat on a cart. However, due to the different areas of the buildings being constructed, the lengths of the prefabricated floor slabs required are different. Since the size of the cart is constant, when transporting a long floor slab, the cart is short and the floor slab is partially suspended, which makes it easy to shake during transportation and has poor stability.

[0005] During transportation, the prefabricated floor slabs are placed directly on the body of the cart. Due to the uneven road surface at the construction site, when the cart moves to the potholes, the body of the cart may tilt, causing the prefabricated floor slabs to slide sideways, causing the center of gravity of the prefabricated floor slabs to shift and no longer remain consistent with the center of gravity of the cart, causing the floor slabs to slide off the body and be damaged, resulting in poor practicality.

[0035] like Figure 1-Figure 6 and Figure 8As shown, the prefabricated floor slab transportation equipment of the present invention comprises a frame 1, a driving structure 2 installed at the bottom of the frame 1, a mounting structure 4 installed on the frame 1, a material discharge structure 5 provided on the frame 1, a telescopic structure 6 matched with the material discharge structure 5, and a fixing structure 7 installed on the frame 1.The material removal structure 5 includes a driving bar 501 and two mounting plates 502 fixedly connected to the driving bar 501. The driving bar 501 is slidably connected to one end of the frame 1. A connecting shaft 503 is rotatably connected between the two mounting plates 502.

After the transportation equipment transfers the prefabricated floor slabs to the interior of the building, multiple prefabricated The floor slab is removed from the equipment. At this time, the first hydraulic rod 506 located on the driving bar 501 drives the rack 505 to slide toward the support frame 504. Since the rack 505 and the gear 507 are meshed with each other, the rack 505 drives the gear 507 and the connecting shaft 503 to rotate counterclockwise. The connecting shaft 503 drives the support frame 504 and the two mounting plates 502 to rotate counterclockwise. The support frame 504 drives the slide 602 at the other end and the second roller 605 to rotate a certain angle. At this time, the support frame 504 and the slide 602 are both in an inclined state, and the second roller 605 is no longer in contact with the bottom surface of the precast floor slab. At this time, the precast floor slab is supported by the support roller 406 and the first roller 511 , and the part close to the second roller 605 is suspended in the air, then the second hydraulic rod 510 on the frame 1 away from the support roller 406 starts to operate, the telescopic end of the second hydraulic rod 510 drives the adjustment frame 509 to slide upward along the two guide strips 508, and the adjustment frame 509 drives the first roller 511 to lift the end of the prefabricated floor slab upward, so that the prefabricated floor slab tilts, and at this time, under the action of gravity, the prefabricated floor slab moves along the tilting direction, and then the prefabricated floor slab slides toward the ground through the first roller 511, the second roller 605 and the support roller 406, and at the same time drives the frame 1 to move backward until the prefabricated floor slab is completely unloaded from the frame 1, at this time, the loading and unloading of the prefabricated floor slab is completed, and the operation efficiency is high. .

When the support frame 504 is fully extended outward, it is necessary to adjust the position of the slide 602 on the support frame 504 according to the length of the prefabricated floor slab. It is only necessary to pull the slide 602 to make the slide 602 slide along the guide rod 601. At the same time, the slide 602 compresses the first spring 603, and then rotate the nut 604 at the end of the guide rod 601 to make the nut 604 resist the bottom of the slide 602, thereby cooperating with the elastic force of the first spring 603 to limit the position of the slide 602. At this time, the adjustment of the position of the slide 602 and the second roller 605 is completed, which is convenient for transporting prefabricated floors of different lengths. At the same time, the setting of the second roller 605 reduces the friction between the prefabricated floor slab and the prefabricated floor slab, which is helpful for the subsequent unloading of the prefabricated floor slab and has strong flexibility.

At the same time, since the other end of the frame 1 is equipped with two universal wheels 206 through the connecting rack 205, it is convenient to adjust the travel direction of the transportation equipment, and two batteries 3 are installed at the bottom of the frame 1 through the placement rack 207, so as to facilitate the provision of stable power to the equipment, and the practicability is strong.

[0038] Specifically, Figure 1-Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, the mounting structure 4 includes a mounting bar 401 and a mounting seat 402 fixedly connected to the end of the mounting bar 401, both ends of the frame 1 are fixedly connected to a mounting bar 401, and both mounting seats 402 are rotatably connected to a mounting rod 403, a bolt 404 is connected between the mounting rod 403 and the mounting seat 402, a push rod 405 is fixedly connected between the two mounting rods 403, and one end of the frame 1 close to the support frame 504 is rotatably connected to a support roller 406, and the support roller 406 is respectively connected to the first rotating roller 511 and the second rotating roller 605 Before placing the prefabricated floor slab on the equipment, it is necessary to first erect the mounting rods 403 on the two mounting strips 401, and rotate the bottom of the mounting rods 403 and the mounting seat 402 90 degrees to make the two mounting rods 403 perpendicular to the horizontal direction, and then fix the mounting rods 403 and the mounting seat 402 as a whole through bolts 404. At this time, the positions of the two mounting rods 403 and the push rod 405 between the two are fixed, and at the same time, it is convenient to install a handle at the end of the push rod 405, and then the whole equipment can be pushed to the specified position through the handle, which is easy to operate.

[0039] Specifically, Figure 1 , Figure 3 , Figure 5 and Figure 7-Figure 9As shown, the fixed structure 7 includes two mounting sleeves 701 and a telescopic rod 702 slidably connected between the two mounting sleeves 701, the upper surface of the frame 1 is fixedly connected with the mounting sleeve 701, the upper surface of the frame 1 is fixedly connected with a fourth hydraulic rod 703, the telescopic end of the fourth hydraulic rod 703 is fixedly connected to the telescopic rod 702, the telescopic rod 702 is rotatably connected with a second rotating shaft 704, both ends of the second rotating shaft 704 are fixedly connected with a first baffle 705, the first baffle 705 is rotatably connected to the end of the telescopic rod 702, and the first baffle 705 is rotatably connected to the end of the telescopic rod 702. Both ends of the second rotating shaft 704 are slidably connected with a limiting ring 706, and a second spring 707 is fixedly connected between a surface of the limiting ring 706 close to the outside and the end of the second rotating shaft 704. The insides of the two first baffles 705 are slidably connected with a second baffle 708, and a plurality of limiting holes 709 are provided on the second baffle 708. The ends of the first baffles 705 are slidably connected with a pull rod 710, and a tension spring 711 is fixedly connected between the inner side of the pull rod 710 and the first baffle 705, and the pull rod 710 is engaged with one of the limiting holes 709.Then, a plurality of prefabricated floor panels are placed flat on the equipment by a forklift. At this time, the prefabricated floor panels are located between the first rotating roller 511, the second rotating roller 605 and the supporting roller 406. Then, the prefabricated floor panels need to be fixed. First, the two first baffles 705 at the ends of the telescopic rod 702 are rotated to a state perpendicular to the ground. Then, the two limiting rings 706 on the second rotating shaft 704 are pulled toward both ends at the same time. At this time, the limiting rings 706 slide along the second rotating shaft 704 toward the end and compress the second spring 707. Until the hexagonal part on the limit ring 706 completely slides out of the groove on the telescopic rod 702, the limit ring 706 no longer blocks the second shaft 704 from rotating on the telescopic rod 702, and the two first baffles 705 can be rotated to a vertical state with the ground through the second shaft 704, and then the extension length of the second baffle 708 inside the first baffle 705 can be adjusted according to the thickness of the multiple prefabricated floor slabs. It is only necessary to pull the pull rod 710 outward so that the end of the pull rod 710 is no longer in contact with the second baffle 708. The second baffle plate 708 is then pulled outward to a suitable length, and the pull rod 710 is released. Under the reset action of the tension spring 711, the end of the pull rod 710 is engaged with another limit hole 709 on the second baffle plate 708. At this time, the position of the second baffle plate 708 is fixed. Then, the two limit rings 706 are released, and then the fourth hydraulic rod 703 located on the upper surface of the frame 1 starts to run, and the telescopic end of the fourth hydraulic rod 703 drives the "U" shape. The telescopic rod 702 of the shaped structure slides toward the inside of the two mounting sleeves 701, and then the telescopic rod 702 drives the second rotating shaft 704 and the two first baffles 705 to move toward the prefabricated floor slab, until the inner side of the first baffle 705 contacts the prefabricated floor slab, thereby effectively blocking and fixing the prefabricated floor slab laterally, avoiding the problem of the prefabricated floor slab sliding laterally and causing the center of gravity to shift due to the tilt of the vehicle body during transportation, thereby enhancing stability. ;

[0040] When the present invention is in use, the length of the entire vehicle body is adjusted according to the length of the prefabricated floor slab to be transported. First, the telescopic end of the third hydraulic rod 606 installed at the bottom of the frame 1 is extended outward, thereby driving the driving bar 501 to slide toward the end of the frame 1. At the same time, the driving bar 501 drives the support frame 504 to extend outward until the driving bar 501 slides to the end of the frame 1, thereby facilitating the subsequent unloading of the prefabricated floor slab. When the support frame 504 is fully extended outward, it is also necessary to adjust the position of the slide 602 on the support frame 504 according to the length of the prefabricated floor slab. 02, the slide 602 slides along the guide rod 601, and the slide 602 compresses the first spring 603, and then the nut 604 at the end of the guide rod 601 is rotated to make the nut 604 contact the bottom of the slide 602, so as to limit the position of the slide 602 in cooperation with the elastic force of the first spring 603. At this time, the adjustment of the position of the slide 602 and the second roller 605 is completed, so as to facilitate the transportation of prefabricated floor slabs of different lengths. At the same time, the setting of the second roller 605 reduces the friction between the prefabricated floor slab and the prefabricated floor slab, which is helpful for the subsequent unloading of the prefabricated floor slab, and has strong flexibility.

[0041] Before placing the prefabricated floor slab on the equipment, it is necessary to first erect the mounting rods 403 on the two mounting bars 401, and rotate the bottom of the mounting rods 403 and the mounting seat 402 by 90 degrees to make the two mounting rods 403 perpendicular to the horizontal direction, and then fix the mounting rods 403 and the mounting seat 402 as a whole through bolts 404. At this time, the positions of the two mounting rods 403 and the push rod 405 between the two are fixed. At the same time, it is convenient to install a handle at the end of the push rod 405, and then the whole device can be pushed to the specified position through the handle, which is easy to operate;

[0042] Then, a plurality of prefabricated floor panels are placed flat on the equipment by a forklift. At this time, the prefabricated floor panels are located between the first rotating roller 511, the second rotating roller 605 and the supporting roller 406. Then, the prefabricated floor panels need to be fixed. First, the two first baffles 705 at the ends of the telescopic rod 702 are rotated to a state perpendicular to the ground. Then, the two limiting rings 706 on the second rotating shaft 704 are pulled toward both ends at the same time. At this time, the limiting rings 706 slide along the second rotating shaft 704 toward the end and compress the second spring 707. Until the hexagonal part on the limit ring 706 completely slides out of the groove on the telescopic rod 702, the limit ring 706 no longer blocks the second shaft 704 from rotating on the telescopic rod 702, and the two first baffles 705 can be rotated to a vertical state with the ground through the second shaft 704, and then the extension length of the second baffle 708 inside the first baffle 705 can be adjusted according to the thickness of the multiple prefabricated floor slabs. It is only necessary to pull the pull rod 710 outward so that the end of the pull rod 710 is no longer in contact with the second baffle 708. The second baffle plate 708 is then pulled outward to a suitable length, and the pull rod 710 is released. Under the reset action of the tension spring 711, the end of the pull rod 710 is engaged with another limit hole 709 on the second baffle plate 708. At this time, the position of the second baffle plate 708 is fixed. Then, the two limit rings 706 are released, and then the fourth hydraulic rod 703 located on the upper surface of the frame 1 starts to run, and the telescopic end of the fourth hydraulic rod 703 drives the "U" shape. The telescopic rod 702 of the shaped structure slides toward the inside of the two mounting sleeves 701, and then the telescopic rod 702 drives the second rotating shaft 704 and the two first baffles 705 to move toward the prefabricated floor slab, until the inner side of the first baffle 705 contacts the prefabricated floor slab, thereby effectively blocking and fixing the prefabricated floor slab laterally, avoiding the problem of the prefabricated floor slab sliding laterally and causing the center of gravity to shift due to the tilt of the vehicle body during transportation, thereby enhancing stability;

[0043] During transportation, the motor 202 at the bottom of the frame 1 can drive the two first rotating shafts 203 to rotate on the mounting frame 201, and at the same time, the two first rotating shafts 203 respectively drive the two wheels 204 to rotate, so as to facilitate the movement of the driving device, solving the problem that the prefabricated floor slab is difficult to transport due to its heavy weight. At the same time, since two universal wheels 206 are installed at the other end of the frame 1 through the connecting frame 205, it is convenient to adjust the travel direction of the transportation equipment, and two batteries 3 are installed at the bottom of the frame 1 through the placement frame 207, so as to facilitate the provision of stable power to the equipment, and the practicability is strong;

[0044] After the transport equipment transfers the prefabricated floor slabs to the interior of the building, it is necessary to unload several prefabricated floor slabs from the equipment. At this time, the first hydraulic rod 506 located on the driving bar 501 drives the rack 505 to slide toward the support frame 504. Since the rack 505 and the gear 507 are meshed with each other, the rack 505 drives the gear 507 and the connecting shaft 503 to rotate counterclockwise. The connecting shaft 503 drives the support frame 504 and the two mounting plates 502 to rotate counterclockwise. The support frame 504 drives the slide 602 at the other end and the second roller 605 to rotate a certain angle. At this time, the support frame 504 and the slide 602 are both in an inclined state, and the second roller 605 no longer contacts the bottom surface of the prefabricated floor slab. At this time, the prefabricated floor slab is supported by the support roller 4 06 and the first rotating roller 511, and the part close to the second rotating roller 605 is suspended, then the second hydraulic rod 510 on the frame 1 that is away from the supporting roller 406 starts to run, and the telescopic end of the second hydraulic rod 510 drives the adjusting frame 509 to slide upward along the two guide strips 508, and the adjusting frame 509 drives the first rotating roller 511 to lift the end of the precast floor slab upward, so that the precast floor slab is tilted, and at this time, the precast floor slab moves along the inclined direction under the action of gravity, and then the precast floor slab slides toward the ground through the first rotating roller 511, the second rotating roller 605 and the supporting roller 406, and at the same time drives the frame 1 to move backward until the precast floor slab is completely unloaded from the frame 1, at this time, the loading and unloading of the precast floor slab is completed, and the operation efficiency is high.
