DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0040] Embodiment 1:

[0041] Reference Figure 1-Figure 12 A flat-laying concrete prefabricated ecological frame hoisting device includes a cylindrical column block 1, and also includes: four circumferentially distributed installation grooves 2, which are arranged at the bottom of the column block 1, wherein a strip plate 4 is rotatably installed in each installation groove 2 through a rotating rod 3. During hoisting, the four strip plates 4 are used to be inserted into four drainage holes 44 respectively, and a lifting part for driving the four strip plates 4 to rotate 90° is provided at the bottom of the column block 1; two colinearly arranged beams 19 are fixedly connected to both sides of the upper end of the column block 1, wherein the two beams 19 are perpendicular to and intersect with the axis of the column block 1, and the lower ends of the two beams 19 are rotatably installed with rollers 22 parallel to the column block 1, and the angle between the beam 19 and the strip plate 4 is 45°, and the beam 19 is provided with an opening and closing part for driving the two rollers 22 to approach and move away from each other.

[0042] Specifically, when in use, the column block 1 is extended into the eco-frame body 43 through the lifting equipment, and the beams 19 on both sides are tilted on the upper port of the eco-frame body 43, that is, the beams 19 only need to be not perpendicular to the four sides of the eco-frame body 43, and then the two rollers 22 are driven away from each other through the opening and closing part. When the rollers 22 hit the inner wall of the eco-frame body 43, the rollers 22 will roll along the inner wall of the eco-frame body 43 and drive the two beams 19 to swing. When the two rollers 22 are respectively pressed against the two right angles of the eco-frame body 43, the two beams 19 will automatically cross between the two right angles of the eco-frame body 43 (such as Fig.11 As shown), at this time, the column block 1 will automatically adjust to the middle of the eco-frame body 43, so there is no need to manually adjust the position of the sling, which indirectly improves the fixing and lifting efficiency of the eco-frame body 43;

[0043] Then, the strip plate 4 is rotated 90° through the rotating rod 3 by the lifting part, and the ends of the four strip plates 4 are extended into the four drainage holes 44 of the ecological frame body 43. At this time, the lower end of the strip plate 4 will be placed on the upper end surface of the turntable 6, and will be limited by the upper end surface of the turntable 6 and cannot be swung down to reset, so that the fixing work of the ecological frame body 43 can be quickly completed, which significantly improves the fixing efficiency of the ecological frame body 43, and the four drainage holes 44 of the ecological frame body 43 are all supported, so that the subsequent lifting process is not prone to shaking and has better stability; after fixing the ecological frame body 43, the ecological frame body 43 is lifted by the lifting equipment, and then moved to the destination, so that the lifting work of the ecological frame body 43 can be completed; during the lifting process, the two rollers 22 stuck at right angles to the ecological frame body 43 can make the column block 1 less likely to be displaced during the lifting process, thereby preventing the strip plate 4 from slipping out of the drainage hole 44 during the lifting process, and significantly improving the stability and safety of the lifting process.

[0044] The upper end of the columnar block 1 is fixedly connected to a vertical rod 26, and the top of the vertical rod 26 is rotatably connected to an end cover 27 with an opening facing downward. An adjustment portion for driving the vertical rod 26 to rotate is provided in the end cover 27, and the adjustment portion includes a second motor 29 fixedly installed in the end cover 27, and the second motor 29 is connected to the vertical rod 26 through two transmission gears 30; a hanging ring 28 is fixedly connected to the top of the end cover 27, and the hanging ring 28 is integrally formed with the end cover 27.

[0045] Specifically, when in use, the hanging ring 28 is fixed to the hook of the lifting equipment, and then the column block 1 is extended into the ecological frame body 43 through the lifting equipment, and the lifting work of the ecological frame body 43 is completed. When laying the ecological frame body 43, the second motor 29 is started. The second motor 29 can drive the vertical pole 26 to rotate through two mutually meshing transmission gears 30, and the vertical pole 26 can drive the column block 1 to rotate, and the column block 1 can drive the ecological frame body 43 to rotate through the strip plate 4, so as to adjust the orientation of the ecological frame body 43, thereby making the installation efficiency of the ecological frame body 43 higher.

[0046] A rubber pad 40 is provided at the top of the end of the above-mentioned strip plate 4, and an insert block 41 is fixedly connected to the lower end of the rubber pad 40. A slot 42 is provided at the upper end of the strip plate 4, and the insert block 41 is inserted into the slot 42. The upper end surface of the rubber pad 40 is arc-shaped and cooperates with the inner wall of the drainage hole 44. Therefore, after the strip plate 4 is extended into the drainage hole 44, the rubber pad 40 in the end of the strip plate 4 can increase the friction between the drainage hole 44 and prevent the strip plate 4 from scratching the drainage hole 44.

[0047] Embodiment 2:

[0048] Reference Figure 1-Figure 4 as well as Figure 6-Figure 8 , which is basically the same as the first embodiment, and furthermore, specifically discloses a specific implementation scheme of the lifting part.

[0049] The lifting part in the flat concrete prefabricated ecological frame hoisting device includes a turntable 6 rotatably connected to the bottom of the columnar block 1, and the turntable 6 is provided with grooves 10 corresponding to the strip plates 4 around it, wherein the side walls of each groove 10 are provided with chamfers 11, and the lower end side walls of each strip plate 4 are provided with inclined surfaces 25 matching the chamfers 11. A driving part for driving the turntable 6 to rotate is provided in the columnar block 1, and when the turntable 6 rotates, the chamfer 11 is pushed toward the direction of the inclined surface 25; the driving part includes a device cavity 5 arranged in the columnar block 1, and a first motor 12 is fixedly installed in the device cavity 5, and a driving gear 13 is fixedly installed on the output shaft of the first motor 12, and a ring gear 14 meshing with the driving gear 13 is installed on the turntable 6.

[0050] Specifically, start the first motor 12, the first motor 12 will drive the annular gear 14 to rotate, and the annular gear 14 will drive the turntable 6 to rotate, and the turntable 6 will drive the slot 10 and the chamfer 11 to revolve around the axis of the turntable 6, and the chamfer 11 will advance in the direction of the inclined surface 25. When the chamfer 11 passes over the inclined surface 25, the strip plate 4 will rotate upward 90° through the rotating rod 3, and the ends of the four strip plates 4 will extend into the four drainage holes 44 of the ecological frame body 43. At this time, the lower end of the strip plate 4 will be placed on the upper end surface of the turntable 6, and will be limited by the upper end surface of the turntable 6 and cannot be swung downward to reset, so that the fixing work of the ecological frame body 43 can be completed quickly, which significantly improves the fixing efficiency of the ecological frame body 43, and the four drainage holes 44 of the ecological frame body 43 are supported, so that the subsequent lifting process is not prone to shaking and has better stability.

[0051] Among them, the strip board 4 has two states. When the strip board 4 is located in the groove 10, it is in a folded state. In this state, the entire device can be easily taken out of the ecological frame body 43 or extended into the ecological frame body 43; and when the strip board 4 is rotated upward by 90°, it will be separated from the groove 10, and it is in an unfolded state.

The support plate 9, the pillar 7 and the turntable 6 are formed as one piece, and the ring gear 14 is fixedly connected to the support plate 9.

[0053] Specifically, when the ring gear 14 rotates, the ring gear 14 will drive the turntable 6 to rotate through the support plate 9 and the pillar 7; when the turntable 6 is subjected to downward pressure, the support plate 9 will share the downward pressure to the inner bottom of the device cavity 5, thereby significantly improving the supporting strength of the turntable 6.

[0054] The lower end of the support plate 9 is provided with an annular plate 15 which abuts against the bottom of the device cavity 5, and a spring 16 is installed between the annular plate 15 and the support plate 9, wherein a protrusion 17 is fixedly connected to the lower end of the support plate 9, and a slot 18 which cooperates with the protrusion 17 is provided at the inner bottom of the device cavity 5. When the strip plate 4 is subjected to load, the protrusion 17 moves downward and is inserted into the slot 18.

[0055] Specifically, when the eco-frame body 43 presses down the strip plate 4, the strip plate 4 will press down the turntable 6, and the turntable 6 will drive the support plate 9 to press down the spring 16, and the support plate 9 will drive the protrusion 17 to press into the slot 18, so during the lifting process, the support plate 9 will be unable to rotate under the action of the protrusion 17 and the slot 18, thereby preventing the turntable 6 from deflecting during the lifting process to ensure the safety of the lifting process, and prevent the ring gear 14 from being damaged due to excessive force. When the strip plate 4 is not subjected to downward pressure, the spring 16 will drive the protrusion 17 to be pulled out of the slot 18 to release the lock on the turntable 6.

[0056] Embodiment three:

[0057] Reference Figure 1-Figure 4 , Figure 7 as well as Fig. 9 , which is basically the same as the second embodiment, and furthermore, specifically discloses a specific implementation scheme of the opening and closing part.

[0058] The opening and closing part in the flat concrete prefabricated ecological frame hoisting device includes a slide groove 20 arranged at the lower ends of the two beams 19, the slide groove 20 penetrates into the device cavity 5, and a double-headed threaded rod 23 is rotatably installed in the slide groove 20, and the thread directions at both ends of the double-headed threaded rod 23 are opposite, wherein both ends of the double-headed threaded rod 23 are threadedly connected with a slide 21, the two slides 21 are respectively slidably connected in the two slide grooves 20, and the two rollers 22 are respectively rotatably connected to the bottom of the two slides 21, and the double-headed threaded rod 23 is connected to the first motor 12 through a transmission component; the transmission component includes a driven gear 24 fixedly mounted on the outer wall of the double-headed threaded rod 23, and the driving gear 13 is an incomplete gear, that is, the gear teeth on the driving gear 13 are only half or less than half, when the driving gear 13 is meshed and connected with the driven gear 24, the driving gear 13 is not meshed with the ring gear 14, and vice versa, when the driving gear 13 is meshed and connected with the ring gear 14, the driving gear 13 is not meshed with the driven gear 24.

[0059] Specifically, when the position of the column block 1 needs to be adjusted, the first motor 12 is started, the first motor 12 will drive the driving gear 13 to rotate, the driving gear 13 will first mesh with the driven gear 24, and drive the driven gear 24 to rotate, the driven gear 24 will drive the double-headed threaded rod 23 to rotate, the double-headed threaded rod 23 will drive the two slides 21 to slide in the slide groove 20 and move away from each other, at this time the two slides 21 will drive the two rollers 22 to move away from each other, and the position adjustment work of the beam 19 and the column block 1 can be completed, when the position adjustment of the beam 19 is completed, the gear teeth on the driving gear 13 will separate from the gear teeth of the driven gear 24, and mesh with the ring gear 14, the ring gear 14 will drive the turntable 6 to rotate through the support plate 9 and the pillar 7, and the adjustment work of the strip plate 4 can be continuously completed.

[0060] Embodiment 4:

[0061] Reference Figure 4-Figure 6 as well as Figure 9-10 , which is basically the same as the third embodiment, and further, a specific implementation scheme for cleaning the strip plate 4 is specifically added.

[0062] The upper end of the above-mentioned strip plate 4 is fixedly connected with a vertical plate 31, and a nozzle 32 facing the end of the strip plate 4 is fixedly installed on the outer wall of the vertical plate 31, wherein a telescopic airbag 33 is fixedly installed between the two slides 21, and an air intake pipe 34 and an exhaust pipe 35 are fixedly connected to the telescopic airbag 33, and a one-way valve is fixedly installed in the air intake pipe 34 and the exhaust pipe 35, and the exhaust pipe 35 is connected to the nozzle 32 through a connecting part; the connecting part includes an annular tube 36 fixedly connected to the outer wall of the columnar block 1, and the end of the exhaust pipe 35 is fixedly connected and communicated with the annular tube 36, and the nozzle 32 is fixedly connected and communicated with the annular tube 36 through a hose 37.

[0063] Specifically, when the two slides 21 approach each other, the two slides 21 will compress the telescopic airbag 33, the telescopic airbag 33 will blow air to the annular tube 36 through the exhaust pipe 35, the annular tube 36 will blow air to the nozzle 32 through the hose 37, and the nozzle 32 will blow off the dust on the force-bearing surface of the strip plate 4 to prevent the dust accumulated on the strip plate 4 from causing wear to the drainage hole 44 and reduce the occurrence of slipping. In addition, during the lifting process, the vertical plate 31 can effectively limit the strip plate 4; when the two slides 21 move away from each other, the two slides 21 will stretch the telescopic airbag 33, and the telescopic airbag 33 will absorb external air through the suction pipe 34.

[0064] The end of the above-mentioned intake pipe 34 is located in the device cavity 5. The outer wall of the cylindrical block 1 is provided with an air inlet groove 38 connected to the device cavity 5, and a filter element 39 is installed in the air inlet groove 38. Therefore, when the intake pipe 34 draws air, the device cavity 5 will draw outside air through the air inlet groove 38. During the absorption, the filter element 39 in the air inlet groove 38 will filter out dust in the air to prevent dust from contaminating the device cavity 5. When the airflow passes through the device cavity 5, the first motor 12 in the device cavity 5 can be cooled to ensure the operating stability of the first motor 12.

[0065] When using the flat concrete prefabricated ecological frame hoisting device, the hanging ring 28 is fixed to the hook of the lifting equipment, and then the column block 1 is extended into the ecological frame body 43 through the lifting equipment, and the cross beams 19 on both sides are tilted and placed on the upper port of the ecological frame body 43, and then the first motor 12 is started, and the first motor 12 will drive the driving gear 13 to rotate, and the driving gear 13 will first mesh with the driven gear 24 and drive the driven gear 24 to rotate, and the driven gear 24 will drive the double-headed threaded rod When the two rollers 22 touch the inner wall of the eco-frame body 43, the rollers 22 will roll along the inner wall of the eco-frame body 43 and drive the two cross beams 19 to swing. When the two rollers 22 are respectively pressed against the two right angles of the eco-frame body 43, the two cross beams 19 will automatically cross between the two right angles of the eco-frame body 43 (such as Fig.11 As shown), at this time, the column block 1 will automatically adjust to the middle of the eco-frame body 43, so there is no need to manually adjust the position of the sling, which indirectly improves the fixing and lifting efficiency of the eco-frame body 43;

[0066] When the position adjustment of the crossbeam 19 is completed, the gear teeth on the driving gear 13 will be separated from the gear teeth of the driven gear 24 and meshed with the ring gear 14. The ring gear 14 will drive the turntable 6 to rotate through the support plate 9 and the pillar 7. The turntable 6 will drive the slot 10 and the chamfer 11 to revolve around the axis of the turntable 6. The chamfer 11 will advance in the direction of the inclined surface 25. When the chamfer 11 passes over the inclined surface 25, the strip plate 4 will rotate upward by 90° through the rotating rod 3, and the ends of the four strip plates 4 will extend into the four drainage holes 44 of the ecological frame body 43. At this time, the lower end of the strip plate 4 will be placed on the upper end surface of the turntable 6, and will be limited by the upper end surface of the turntable 6 and cannot be swung downward to reset, so that the fixing work of the ecological frame body 43 can be completed quickly, which significantly improves the fixing efficiency of the ecological frame body 43, and the four drainage holes 44 of the ecological frame body 43 are all supported, so that the subsequent lifting process is not prone to shaking and has better stability.

[0067] After fixing the eco-frame body 43, lift the eco-frame body 43 by the lifting equipment, and then move it to the destination to complete the hoisting work of the eco-frame body 43. During the hoisting process, the two rollers 22 stuck at the right angles of the eco-frame body 43 can prevent the column block 1 from being easily displaced during the hoisting process, thereby preventing the strip plate 4 from slipping out of the drainage hole 44 during the hoisting process, significantly improving the stability and safety of the hoisting process; then reverse the first motor 12, first reverse and reset the turntable 6, and the four strip plates 4 will automatically swing down and reset, and then reverse the double-headed threaded rod 23, and the two rollers 22 will no longer be pressed against the two right angles of the eco-frame body 43, and then the column block 1 can be pulled out of the eco-frame body 43.
