Description

Technical Field

[0001] The utility model relates to the field of laminated slab construction, in particular to a top-support type installation device for prefabricated laminated slabs. Background Art

[0002] In the installation process of traditional laminated slabs, first, a tower crane is used to lift the laminated slab to be installed, and support rods are arranged under the four corners of the laminated slab. Construction workers stand on the beam-column structure of this floor and move the laminated slab to the designated position through manual guidance. Then the tower crane slowly descends, and the construction workers assist in adjusting the position of the laminated slab until it is caught by the support rods below. However, the accuracy of this installation method is relatively low. In order to improve the installation efficiency, the laminated slabs are usually made smaller so that they can be completely erected on the vertical poles. Since there are gaps between the laminated slabs and the wall columns, formwork needs to be erected between the laminated slabs and the wall columns first, and then cement mortar is poured to fill these gaps. Finally, concrete can be poured on the floor surface of the laminated slabs. The ideal state of this installation method is that the two ends of the laminated slab are directly erected on the beam or column, and the contact surface width is about 1 centimeter, thus avoiding the cumbersome steps of formwork erection and cement mortar pouring. However, due to the accuracy limitation of the traditional installation process, it is difficult to meet such installation position accuracy requirements. In addition, the process of manually assisting the tower crane to adjust the horizontal position of the laminated slab takes a long time, reducing the overall work efficiency, and also occupying the tower crane for a long time, which does not meet the requirements of rapid construction. Therefore, a top-support type installation device for prefabricated laminated slabs is proposed to solve the above problems. Content of the Utility Model

Specific embodiments

[0029] As shown Figures 1-5 in the figure, an assembled laminated slab top bracing installation device includes an automatic moving trolley 1 for driving the device to move. A lifting bracing mechanism 2 is arranged on the top of the automatic moving trolley 1 for bracing the laminated slab from the bottom. A positioning system 3 is arranged at the top end of the lifting bracing mechanism 2 for positioning the central position of the laminated slab. An attitude adjustment mechanism 4 is arranged at the lifting end of the lifting bracing mechanism 2 for adjusting the installation attitude of the laminated slab before the lifting bracing mechanism 2 braces it.

[0030] In a preferred solution, the automatic moving trolley 1 can be one of an RGV trolley or an AGV trolley. In this embodiment, the AGV trolley is preferred.

[0031] In a preferred solution, the lifting bracing mechanism 2 includes a lifting support mechanism 201 fixedly arranged on the top of the automatic moving trolley 1 and a lifting bracing component 202 that can be lifted and arranged on the lifting support mechanism 201.

[0032] Among them, the lifting support mechanism 201 includes an outer sleeve 2010 arranged on the top of the automatic moving trolley 1. The top end of the outer sleeve 2010 is open, and a plurality of equally spaced lifting grooves 2011 are arranged on the side wall surface. A plurality of lifting cylinders 2012 corresponding to the lifting grooves 2011 are arranged at the bottom of the side surface of the outer sleeve 2010.

[0033] The lifting bracing component 202 includes a lifting cylinder 2020 that is movably inserted into its interior through the top opening of the outer sleeve 2010. A plurality of pushing seats 2021 corresponding to the number and position of the lifting grooves 2011 are fixedly arranged on the side wall at the bottom of the lifting cylinder 2020. The end of the pushing seat 2021 movably passes through the corresponding lifting groove 2011 and is connected to the telescopic end of the corresponding lifting cylinder 2012 at the bottom. Four outwardly extending support arms 2022 are equally spaced and fixedly arranged at the top end of the lifting cylinder 2020. The downward viewing angles of the four support arms 2022 are in a cross shape for supporting the laminated slab.

[0034] It should be noted that a reinforcing plate 2023 is fixedly arranged at the angle between the support arm 2022 and the lifting cylinder 2020.

[0035] In this embodiment, the number of the lifting grooves 2011, the lifting cylinders 2012 and the pushing seats 2021 is four, and the corresponding three are on the same axis.

[0036] During use, through the synchronous lifting of the four lifting cylinders 2012, the lifting cylinder 2020 can be lifted at the top of the outer sleeve 2010, so that the support arm 2022 at the end of the lifting cylinder 2020 can be lifted above the installation position of the laminated board. Before the laminated board is installed, it can be supported from below, which is convenient for adjustment before installation. There is no need for a crane to continuously hoist, so that the crane can hoist the next laminated board, effectively improving the installation efficiency.

[0037] In the preferred solution, the positioning system 3 includes an installation groove 301 opened at the top end of the lifting cylinder 2020. A transparent reference ring 303 is provided at the center of the installation groove 301. A transparent connecting rod 302 connected to the inner wall of the installation groove 301 is provided on the outer wall surface of the transparent reference ring 303. Both the transparent reference ring 303 and the transparent connecting rod 302 are made of polycarbonate transparent material and are integrally formed. A vision camera 304 with its visual axis passing through the center of the transparent reference ring 303 is installed on the bottom wall of the installation groove 301, and the vision camera 304 is equipped with a vision recognition system.

[0038] During use, by setting a target point at the center of the bottom of the laminated board, the offset between the transparent reference ring 303 and the target point can be recognized through the vision camera 304, and then the support position between the laminated board and the top end of the lifting cylinder 2020 can be known.

[0039] Among them, the cross-section of the installation groove 301 is a tapered groove that is wider at the top and narrower at the bottom, which is convenient for expanding the viewing angle range of the vision camera 304, and a lighting lamp 305 is also provided inside it.

[0040] In the preferred solution, the attitude adjustment mechanism 4 includes a lateral adjustment mechanism 41 provided outside the top support end of the lifting cylinder 2020, a longitudinal adjustment mechanism 42 movably provided on the lateral adjustment mechanism 41, a vertical adjustment mechanism 43 movably provided on the longitudinal adjustment mechanism 42, a rotary adjustment mechanism 44 movably provided on the vertical adjustment mechanism 43, and four adjustment support parts 45 are provided at the top of the rotary adjustment mechanism 44. The adjustment support parts 45 and the support arm 2022 are staggered. Among them, the longitudinal adjustment mechanism 42, the vertical adjustment mechanism 43, and the rotary adjustment mechanism 44 are all sleeved outside the lifting cylinder 2020 and are provided with a space for moving adjustment.

[0041] It should be noted that when the four adjustment support parts 45 are at the bottommost position, the top end surface is lower than the top end surface of the support arm 2022. In addition, when the lifting cylinder 2020 reaches the lowest position, the lateral adjustment mechanism 41 is located above the lifting cylinder 2020 to avoid affecting the normal lifting of the lifting cylinder 2020.

[0042] During use, the four adjusting support parts 45 can be lifted above the support arm 2022 through the vertical adjusting mechanism 43 to support the laminated board. Then, through the adjustment of the transverse adjusting mechanism 41 and the longitudinal adjusting mechanism 42, the laminated board can be adjusted in both the transverse and longitudinal directions. In cooperation with the positioning system 3, the center of the laminated board is made to coincide with the center of the top end of the lifting cylinder 2020. In addition, the circumferential attitude of the laminated board can be adjusted through the rotation adjusting mechanism 44 to make it meet the installation attitude, and then the automatic adjustment and installation of the laminated board can be realized in cooperation with the lifting and supporting mechanism 2.

[0043] Among them, the transverse adjusting mechanism 41 includes a support platform 410 fixedly arranged outside the lifting cylinder 2020. At the two symmetrical edges of the top of the support platform 410 in the transverse direction, there are transversely sliding support rods 411 fixedly arranged, and at the bottom, there is a transverse adjusting oil cylinder 412 corresponding to the transversely sliding support rods 411.

[0044] The longitudinal adjusting mechanism 42 includes a transverse moving frame 420 sleeved outside the lifting cylinder 2020. At the two symmetrical edges of the bottom of the transverse moving frame 420 in the transverse direction, there are transversely sliding sleeves 421 corresponding to the transversely sliding support rods 411 fixedly arranged, and at the ends of the two edges, there are also transverse pushing plates 422 arranged. The transversely sliding sleeves 421 are slidably sleeved outside the corresponding transversely sliding support rods 411. The telescopic end of the transverse adjusting oil cylinder 412 is connected to the corresponding transverse pushing plate 422. At the two symmetrical edges of the transverse moving frame 420 in the longitudinal direction, there are longitudinally sliding support rods 425 arranged. On the outside of the longitudinally sliding support rods 425, there is an extension platform 423, and the extension platform 423 is connected to the transverse moving frame 420, and at its top, there is a longitudinal adjusting oil cylinder 424.

[0045] During use, through the telescopic movement of the transverse adjusting oil cylinder 412, the transverse moving frame 420 can slide through the transversely sliding sleeves 421 on the transversely sliding support rods 411, thereby driving the mechanisms thereon to move transversely and achieving the effect of transverse adjustment.

[0046] The vertical adjusting mechanism 43 includes a longitudinal moving frame 430 sleeved outside the lifting cylinder 2020. At the two symmetrical edges of the bottom of the longitudinal moving frame 430 in the longitudinal direction, there are longitudinally sliding sleeves 431 corresponding to the longitudinally sliding support rods 425 fixedly arranged, and on the sides of the ends of the two edges, there are also longitudinal pushing plates 432 arranged. The longitudinally sliding sleeves 431 are slidably sleeved on the corresponding longitudinally sliding support rods 425. The telescopic end of the longitudinal adjusting oil cylinder 424 is connected to the corresponding longitudinal pushing plate 432. At the four corners of the top of the longitudinal moving frame 430, there are jacking oil cylinders 433 arranged.

[0047] During use, by adjusting the telescopic movement of the longitudinal adjustment oil cylinder 424, the longitudinal movement frame 430 can slide on the longitudinal sliding support rod 425 through the longitudinal sliding sleeve 431, thereby driving the mechanism thereon to move longitudinally and achieving the effect of longitudinal adjustment.

[0048] It should be noted that when the telescopic ends of the longitudinal adjustment oil cylinder 424 and the longitudinal adjustment oil cylinder 424 extend half of their stroke, both the longitudinal movement frame 430 and the transverse movement frame 420 are located at the middle position.

[0049] The rotation adjustment mechanism 44 includes a rotation adjustment seat 440 fixed to the telescopic ends of the four jacking oil cylinders 433. A rotation adjustment ring 441 is rotatably arranged on the top of the rotation adjustment seat 440. Four adjustment support parts 45 are fixedly arranged on the rotation adjustment ring 441 at equal intervals. An L-shaped support frame 442 is arranged at the bottom of the rotation adjustment seat 440. A driving motor 443 is arranged on the L-shaped support frame 442. A transmission gear 444 is arranged at the output end of the driving motor 443. A rotation gear ring 445 meshing with the transmission gear 444 is fixedly arranged outside the rotation adjustment ring 441.

[0050] During use, through the drive of the driving motor 443 and the transmission relationship between the transmission gear 444 and the rotation gear ring 445, the rotation adjustment ring 441 can rotate on the rotation adjustment seat 440, and then drive the four adjustment support parts 45 to rotate, thereby adjusting the circumferential attitude of the laminated board thereon.

[0051] It should be noted that the spaces at the centers of the transverse movement frame 420, the longitudinal movement frame 430, the rotation adjustment seat 440, and the rotation adjustment ring 441 all meet the requirements for their movement outside the lifting cylinder 2020.

[0052] The adjustment support part 45 includes an L-shaped top support frame 450 fixed to the top of the rotation adjustment ring 441. The L-shaped top support frame 450 is arranged on the top of the rotation adjustment ring 441 in a side-down state, and a stiffening plate 451 is arranged at its corner. The L-shaped design can effectively increase the contact area with the laminated board.

[0053] Embodiment 2

[0054] Further described in combination with Embodiment 1, as Figure 1 and Figure 6 shown in the structure, in order to prevent the device from having a center of gravity offset after the laminated board is adjusted, a center of gravity adjustment mechanism 5 is further included on the automatic moving trolley 1 in this embodiment.

[0055] In a preferred embodiment, the center of gravity adjustment mechanism 5 includes a center of gravity rotation offset mechanism disposed on the top of the automatic mobile trolley 1, and a plurality of sliding counterweight parts 505 movably disposed around the center of gravity rotation offset mechanism on the top of the automatic mobile trolley 1. The sliding counterweight parts 505 can change their positions by connecting with the rotating end of the center of gravity rotation offset mechanism, thereby changing the center of gravity state. In this embodiment, the number of the sliding counterweight parts 505 is four. In the initial state, the four sliding counterweight parts 505 are equidistantly arranged around the outside of the center of gravity rotation offset mechanism.

[0056] In a preferred embodiment, the center of gravity rotation offset mechanism includes a rotating support ring 501 fixedly disposed on the top of the automatic mobile trolley 1. The rotating support ring 501 is sleeved outside the lifting support mechanism 2. A rotating transmission ring 503 is rotatably disposed on the top of the rotating support ring 501. A rotating driven gear ring 504 is disposed on the inner wall surface of the rotating support ring 501. A transmission motor 507 is further disposed on the top of the automatic mobile trolley 1 inside the rotating support ring 501. A driving gear 506 meshing with the rotating driven gear ring 504 is installed at the output end of the transmission motor 507.

[0057] During use, through the drive of the transmission motor 507 and the meshing transmission relationship between the rotating driven gear ring 504 and the driving gear 506, the rotating transmission ring 503 can rotate on the top of the rotating support ring 501.

[0058] In a preferred embodiment, the sliding counterweight part 505 includes a counterweight block 5050 slidably disposed around the center of gravity rotation offset mechanism on the top of the automatic mobile trolley 1. A clamp 5051 for clamping the rotating transmission ring 503 therein is disposed on the top side surface of the counterweight block 5050. The cross-section of the clamp 5051 is in the shape of an L inverted sideways. A clamping oil cylinder 5052 is disposed through the side plate of the clamp 5051. A clamping piece 5053 is installed at the telescopic end of the clamping oil cylinder 5052 through the side plate of the clamp 5051.

[0059] During use, through the telescoping of the clamping oil cylinder 5052, the telescoping of the clamping piece 5053 on the side surface of the rotating transmission ring 503 can be controlled. Thus, when it is necessary to adjust the position of the sliding counterweight part 505, it can be clamped by the clamping piece 5053 and the rotating transmission ring 503, and it can follow the rotation of the rotating transmission ring 503 until it rotates to the corresponding position. Then, through the retraction of the clamping piece 5053, the effect of disengaging from the rotating transmission ring 503 is achieved.

[0060] In a preferred embodiment, a plurality of annular sliding rails 502 surrounding the center of gravity adjustment mechanism 5 are disposed on the top of the automatic mobile trolley 1. In this embodiment, the number of the annular sliding rails 502 is two. A sliding groove 5054 slidably connected with the annular sliding rail 502 is disposed at the bottom of the counterweight block 5050. A plurality of balls 5055 are disposed on the top wall of the sliding groove 5054 for reducing the friction during sliding.

[0061] When this embodiment is in use, the four sliding weight parts 505 can be moved to the same position, so as to adjust the center of gravity offset. At the same time, when the center of gravity is not offset, the four sliding weight parts 505 can also be dispersed to different positions.

[0062] Example 3

[0063] Further illustrate with reference to Examples 1 and 2, Figures 1-7 The structure shown is a construction method of a prefabricated composite plate top support installation device, the method comprising:

[0064] S1. Hoist the device to the lower floor of the installation position of the composite plate, and set marking lines on the floor corresponding to the central axis of the continuously installed composite plates. The support rods of the composite plates are located on both sides of the marking lines, and installation position marks corresponding to the center points of each composite plate are set on the marking lines. Then move the device to the installation position mark of the first composite plate, and make sure that the automatic moving trolley 1 has recognized the marking line.

[0065] S2. Mark the cross center line at the bottom of the composite plate, and then use the tower crane to lead the composite plate to the top of the device. At this time, the lifting and supporting mechanism 2 of the device lifts the end of the lifting cylinder 2020 and the support arm 2022 to above the installation position of the composite plate, and lifts the adjustment support part 45 of the posture adjustment mechanism 4 to above the support arm 2022 to receive the composite plate. After the tower crane places the composite plate on the adjustment support part 45, it releases the connection with the composite plate and starts the lifting work of the next composite plate.

[0066] S3. Identify the cross center line at the bottom of the superimposed plate through the positioning system 3, judge the circumferential posture and center point deviation of the superimposed plate, and use the posture adjustment mechanism 4 to perform lateral and longitudinal movement adjustments and circumferential posture rotation adjustments, so that the posture of the superimposed plate meets the installation requirements, and then lower the adjustment support part 45 to make the superimposed plate fall onto the support arm 2022. If the deviation of the superimposed plate from the installation requirements is too large, multiple adjustments can be made. After the superimposed plate falls onto the support arm 2022, use the adjustment support part 45 to lift it up again, and adjust it until the installation requirements are met.

[0067] S4. Then, the lifting cylinder 2020 is lowered to allow the composite plate to be stably erected on the edge of the beam-column structure and the support rods. The lifting cylinder 2020 continues to descend to separate it from the composite plate, completing the installation of the composite plate. The device moves along the marking line to the next installation position mark.

[0068] S5. Repeat steps S2-S4 until all the composite panels in the area are installed.

[0069] It should be noted that after all the floor composite slabs are installed, the installation device can be lifted from the side between the floors by a tower crane, or before the last composite slab is installed, it can be lifted to the upper floor slab by a tower crane, and the last composite slab is installed by a tower crane.

[0070] In the preferred solution, the specific identification method of the positioning system 3 in step S3 includes:

[0071] S31. Image acquisition, using the vision camera 304 to acquire an image containing the intersection of the cross center line and the transparent reference ring 303.

[0072] S32. Feature extraction, using the threshold segmentation method to extract the position of the intersection of the cross center line;

[0073] Using methods such as the Hough line transform to extract the position of the cross center line;

[0074] Using edge detection and Hough transform methods to extract the center position of the transparent reference ring 303;

[0075] Using edge detection and Hough line transform methods to extract the position of the preset diameter of the transparent reference ring 303.

[0076] S33. Deviation calculation, calculating the deviation between the coordinates (xA, yA) of the intersection of the cross center line in the image and the center coordinates (xB, yB) of the transparent reference ring;

[0077] Calculating the direction deviation between the cross center line and the preset diameter of the transparent reference ring 303, and obtaining the direction deviation by calculating the included angle between the two straight lines.

[0078] S34. Position and direction adjustment, adjusting the position of the target point according to the center deviation value until the deviation value is close to zero;

[0079] Adjusting the direction of the target point according to the direction deviation value until the deviation value is close to zero.

[0080] S35. Closed-loop control, continuously repeating steps S31 - S34 until the intersection of the cross center line is aligned with the center of the transparent reference ring 303, and the cross center line is aligned with the preset diameter of the transparent reference ring.

[0081] It should be noted that the preset diameter is parallel to the central axis of the installed composite slab, and the coordinate deviation calculation formula is: deviation x = xA - xB; deviation y = yA - yB.
