Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a hoisting device for building construction materials. Background Technology

[0002] Currently, when hoisting sheet materials, the majority of the method involves stacking the sheets together, binding them tightly, and then suspending the entire assembly on a crane for transport. However, the binding process is cumbersome, time-consuming, and labor-intensive. During hoisting, the sheets are highly unstable, and their position cannot be adequately controlled, making them prone to tilting and causing accidents, thus posing certain safety hazards.

[0003] In response to the above situation, Chinese invention patent CN110077951B discloses a panel hoisting device for building construction, including a hanger and a hanging plate frame. The hanger includes a hanging plate, four slings, and a hook. The hanging plate is a circular steel plate with a hook at the center of its upper surface. Four slings are evenly spaced on the circumference of the lower surface of the circular steel plate. The hanging plate frame is a steel frame including two rectangular fixed plates, two sliding plates, and four columns. The free ends of the four slings are fixedly connected to the two sliding plates on both sides of the upper fixed plates via corresponding pulley mechanisms and through through holes. This allows the two sliding plates to open and close according to the tension of the slings to clamp or release the panels for hoisting. This invention provides a panel hoisting device for building construction with advantages such as simple structure, easy manufacturing, improved hoisting efficiency and stability, enhanced construction safety, faster project progress, and reduced project costs. However, after the board is placed on the fixed plate, it is not placed in the center of the fixed plate, which makes the distance between the two slides and the side of the board different. As a result, when the two slides clamp the board, the hanging frame is prone to tilting during the hoisting process. There is a defect that the board may not be clamped tightly and fall out of the tilted hanging frame. Summary of the Invention

[0004] Therefore, the purpose of this invention is to provide a hoisting device for building construction panels to solve the technical problem of safety hazards in the prior art when hoisting panels.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A hoisting device for building construction materials includes:

[0007] The support plate is a rectangular plate. The length direction of the support plate is defined as the left-right direction, and the width direction of the support plate is defined as the front-back direction. Guide rods are symmetrically arranged on the top surface of the support plate near the four corners.

[0008] The cover plate is a rectangular plate, which is set on the support plate and slidably assembled on the guide rod in the vertical direction. A first hook is set in the middle of the top surface of the cover plate.

[0009] The connecting assembly includes a connecting unit, a connecting plate, and a second hook. The connecting unit is symmetrically arranged with four sets of guide rods. The connecting unit includes a first guide wheel, a second guide wheel, and a connecting wire rope. The first guide wheel is set on the top surface of the support plate, and the second guide wheel is set on the top of the cover plate, corresponding to the first guide wheel. One end of the connecting wire rope is fixedly connected to the bottom of the cover plate, corresponding to the first guide wheel, and the other end passes around the first guide wheel and through the cover plate, and is fixed to the connecting plate under the guidance of the second guide wheel. The second hook is set at the center of the top surface of the connecting plate.

[0010] The limiting assembly includes adjustable limiting units symmetrically arranged in the left-right and front-back directions. The limiting units are used to connect the support plate and the cover plate in the up-down direction and to stop the support plate and the cover plate in the up-down direction. The part of the limiting unit between the support plate and the cover plate is used to stop the plate material in the left-right and front-back directions respectively.

[0011] Preferably, the limiting unit includes a limiting rod, a limiting block, and a fastening nut. The limiting rod is a threaded rod that passes through the cover plate and the support plate from top to bottom. The limiting block is located at the bottom of the limiting rod and extends radially along the limiting rod. The fastening nut is threadedly connected to the portion of the limiting rod above the cover plate. The cover plate and the support plate are provided with limiting holes corresponding to the limiting rod and the limiting block for the limiting rod and the limiting block to pass through. Multiple limiting holes are provided at equal intervals along the left-right direction or the front-back direction where the limiting unit is located. The bottom of the support plate is provided with an inwardly recessed adjusting groove corresponding to the limiting holes and extending along the direction at intervals along the limiting holes. The adjusting groove communicates with the limiting holes and is used to allow the limiting block to rotate at a set angle within the adjusting groove so that the limiting block and the support plate are in a blocking engagement in the vertical direction.

[0012] Preferably, the limiting block is a strip-shaped structure, and the limiting blocks are symmetrically arranged on both radial sides of the limiting rod. The end of the limiting rod is provided with a fixed handle whose extension direction is perpendicular to the extension direction of the limiting block.

[0013] Preferably, the bottom of the adjusting groove is provided with an upwardly recessed stop groove on both sides corresponding to each limiting hole. The stop groove is adapted to the size of the limiting block and extends along the direction of the interval of the limiting holes.

[0014] Preferably, the fastening nut is provided with adjusting wrenches symmetrically on both radial sides, and the adjusting wrench includes an upwardly extending arc-shaped segment and a horizontal segment connected to the arc-shaped segment.

[0015] Preferably, the limiting holes on the support plate and the cover plate are provided in at least two rows in both the left-right and front-back directions, and the number of limiting units provided in the four directions of the cover plate is the same as the number of rows of corresponding limiting holes.

[0016] Preferably, a scale line is provided between two adjacent rows of limiting holes on the cover plate, with the same direction of extension as the limiting holes. The scale line is used to show the distance between the position and the corresponding center line of the cover plate.

[0017] Preferably, the first guide wheel is provided with supporting vertical plates on both sides of its axial direction, and a connecting horizontal shaft is rotatably provided between the supporting vertical plates. The connecting horizontal shaft passes through the first guide wheel coaxially and is fixedly connected to the first guide wheel, and the height of the supporting vertical plates is not lower than the height of the first guide wheel.

[0018] The beneficial effects of the above technical solution are as follows: The panel hoisting device for building construction of the present invention can preliminarily determine the position of the panel before placing it on the support plate by setting scale lines on the cover plate. By inserting limiting rods from top to bottom on the adjacent sides of the cover plate and rotating the limiting rods to align the limiting blocks on the limiting rods with the stop grooves, the hoisting equipment connects with the first hook to raise the cover plate to an appropriate height. The portions of the limiting rods on the adjacent sides located between the support plate and the cover plate respectively form limiting surfaces. The two limiting surfaces together form a limiting angle for panel installation, which limits the placement position of the panel on the support plate, ensuring that the panel is in the center position on the support plate, facilitating installation. After the sheet material is placed, install the remaining two side limit rods to limit the sheet material. Disconnect the hoisting equipment from the first hook and tighten the fastening nut using an adjusting wrench. The limit block engages in the stop groove to stop the limit rod in the circumferential direction and the stop groove in the vertical direction. The limit block also stops the support plate in the vertical direction, fixing the support plate, sheet material, and cover plate together in the vertical direction and ensuring that the connection between the limit rod and the support plate will not disengage during transportation. Connect the hoisting equipment to the second hook. As the second hook moves upward, it causes the connecting wire rope to slide, pressing the cover plate against the top of the sheet material. The cover plate and support plate are then lifted together for transportation of the sheet material.

[0019] The hoisting device for transporting building construction materials of the present invention has the following advantages:

[0020] 1. Simple structure, easy to process and manufacture;

[0021] 2. Simple operation and easy installation. The cover plate is equipped with scale lines. By inserting limit rods from top to bottom on the adjacent sides of the cover plate, the position of the board can be initially determined before placing the board on the support plate. This facilitates the placement of the board and ensures that the board is centered on the support plate, preventing the hoisting device from shifting during hoisting.

[0022] 3. Construction safety: The second hook and wire rope allow the support plate and cover plate to clamp the sheet metal vertically, reducing slippage. Limiting rods inserted into the support plate and cover plate stop the sheet metal around its circumference, preventing slippage and ensuring safe hoisting. A limiting block at the bottom of the limiting rod inserts into the stop groove to cooperate with the support plate vertically. Simultaneously, the limiting block and the fastening nut together secure the support plate, sheet metal, and cover plate, ensuring the limiting rod's position remains unchanged during hoisting and guaranteeing hoisting safety.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] A specific embodiment of the building construction panel hoisting device of the present invention is as follows:

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the building construction panel hoisting device of the present invention includes a support plate 1, a cover plate 3, a connecting component and a limiting component.

[0030] like Figure 1 and Figure 2 As shown, the support plate 1 is a rectangular plate. The length direction of the support plate 1 is defined as the left-right direction, and the width direction of the support plate 1 is defined as the front-back direction. Guide rods 2 are symmetrically arranged on the top surface of the support plate 1 near the four corners.

[0031] like Figure 1As shown, the cover plate 3 is a rectangular plate. The cover plate 3 is set on the support plate 1 and is slidably assembled on the guide rod 2 in the vertical direction. A first hook 4 is set at the middle position of the top surface of the cover plate 3.

[0032] like Figure 1 and Figure 2 As shown, the support plate 1 and the cover plate 3 are symmetrically provided with limiting holes 5 in the four directions of left, right, front, and back. Two rows of limiting holes 5 are provided in each direction, and multiple limiting holes 5 are evenly spaced along the direction within each row. A scale line 6 is provided between two adjacent rows of limiting holes 5 in any direction of the cover plate 3. The extension direction of the scale line 6 is the same as the direction in which the limiting holes 5 are spaced, and the scale line 6 is used to indicate the distance from that position to the corresponding center line of the cover plate 3. A recessed adjustment groove 7 is provided at the bottom of the support plate 1 corresponding to the limiting holes 5 and extending along the direction in which the limiting holes 5 are spaced. The adjustment groove 7 communicates with the limiting holes 5.

[0033] like Figure 1 As shown, the connecting assembly includes a connecting unit, a connecting plate 8, and a second hook 9. Four sets of connecting units are symmetrically arranged corresponding to the guide rod 2. Each connecting unit includes a first guide wheel 10, a second guide wheel 11, and a connecting wire rope 12. The first guide wheel 10 is positioned on the top surface of the support plate 1, corresponding to the guide rod 2. The second guide wheel 11 is positioned on the top of the cover plate 3, corresponding to the first guide wheel 10. One end of the connecting wire rope 12 is fixedly connected to the bottom of the cover plate 3 corresponding to the first guide wheel 10, and the other end passes around the first guide wheel 10 and through the cover plate 3, where it is fixed to the connecting plate 8 under the guidance of the second guide wheel 11. The second hook 9 is positioned at the center of the top surface of the connecting plate 8. In this embodiment, support vertical plates 13 are provided on both sides of the first guide wheel 10 along its axial direction. A connecting horizontal shaft is rotatably provided between the support vertical plates 13. The connecting horizontal shaft passes through the first guide wheel 10 coaxially and is fixedly connected to the first guide wheel 10. The height of the support vertical plates 13 is equal to the height of the first guide wheel 10, so that in the unloaded state, the cover plate 3 is pressed against the support vertical plates 13 without contacting the first guide wheel 10, thereby increasing the service life of the first guide wheel 10.

[0034] like Figure 1 and Figure 3As shown, the limiting assembly includes limiting units corresponding to the limiting holes 5 in the left, right, front, and rear directions of the cover plate 3. The number of limiting units in the four directions of the cover plate 3 is the same as the number of rows of corresponding limiting holes 5. The limiting unit includes a limiting rod 14, a limiting block 15, and a fastening nut 16. The limiting rod 14 is a threaded rod. The limiting block 15 is a strip-shaped structure, symmetrically arranged on both radial sides of the limiting rod 14. The limiting rod 14 passes through the limiting holes 5 on the cover plate 3 and the support plate 1 from top to bottom, allowing the limiting block 15 to extend into the adjusting groove 7 and rotate at a set angle within the adjusting groove 7 to achieve a stop engagement between the limiting block 15 and the support plate 1 in the vertical direction. The fastening nut 16 is threadedly connected to the portion of the limiting rod 14 located above the cover plate 3. The limiting rod 14, the limiting block 15, and the fastening nut 16 are used to connect the support plate 1 and the cover plate 3 in the vertical direction and to stop the support plate 1 and the cover plate 3 in the vertical direction. The part of the limiting rod 14 between the support plate 1 and the cover plate 3 is used to stop the plate in the left-right and front-back directions respectively.

[0035] like Figure 2 As shown, in this embodiment, the bottom of the adjusting groove 7 is provided with an upwardly recessed stop groove 17 on both sides of each limiting hole 5. The stop groove 17 is adapted to the size of the limiting block 15 and extends along the direction of the interval of the limiting holes 5, so that the limiting block 15 can be engaged in the stop groove 17 when the fastening nut 16 is tightened. When the limiting block 15 and the fastening nut 16 are used to fasten the support plate 1, the plate and the cover plate 3, the limiting block 15 stops in the axial direction of the limiting rod 14 with the stop groove 17, ensuring that the stop engagement between the limiting block 15 and the support plate 1 will not be released.

[0036] like Figure 3 As shown, in this embodiment, the end of the limiting rod 14 is provided with a fixed handle 18 whose extension direction is perpendicular to the extension direction of the limiting block 15, so as to determine the rotation of the limiting block 15 in the adjusting groove 7. In this embodiment, adjusting wrenches 19 are symmetrically arranged on both radial sides of the fastening nut 16. The adjusting wrench 19 includes an upwardly extending arc-shaped segment and a horizontal segment connected to the arc-shaped segment. The adjusting wrench 19 facilitates the tightening of the fastening nut 16. Moreover, by providing an upwardly extending arc-shaped segment, it is still easy to hold the adjusting wrench 19 to tighten the fastening nut 16 when the fastening nut 16 is in contact with the cover plate 3, making the operation convenient.

[0037] The specific working principle of the building construction panel hoisting device of the present invention is as follows: Determine the length and width of the panel to be hoisted. Using the scale lines 6 on the cover plate 3, locate the limiting holes 5 corresponding to half the length and width of the panel in two adjacent directions. Insert limiting rods 14 from top to bottom into the corresponding limiting holes 5 in these two directions. Rotate the limiting rods 14 so that the limiting block 15 aligns with the stop groove 17. Connect the hoisting device to the first hook 4 and raise the cover plate 3 to an appropriate height. The portions of the limiting rods 14 on both sides located between the support plate 1 and the cover plate 3 respectively form limiting surfaces. The two limiting surfaces together form a limiting angle for panel installation, thus limiting the placement position of the panel on the support plate 1. After the panel is placed, release the hoisting device from the first hook 4. The connection of hook 4 allows cover plate 3 to fall above the plate under gravity. Turning the adjusting wrench 19 to tighten the fastening nut 16 causes the limiting block 15 to engage in the stop groove 17, thus blocking the limiting rod 14 in the circumferential direction and the support plate 1 in the vertical direction. Installing the remaining two limiting rods 14 on both sides fully limits the plate in the circumferential direction. The limiting rods 14, limiting blocks 15, and fastening nuts 16 fix the support plate 1, the plate, and cover plate 3 together in the vertical direction. Connecting the hoisting equipment to the second hook 9, the second hook 9 moves upward, causing the connecting wire rope 12 to slide, pressing the cover plate 3 against the top of the plate, and lifting the cover plate 3 and support plate 1 together for transporting the plate.

[0038] The hoisting device for transporting building construction materials of the present invention has the following advantages:

[0039] 1. Simple structure, easy to process and manufacture;

[0040] 2. Simple operation and easy installation. The cover plate is equipped with scale lines. By inserting limit rods from top to bottom on the adjacent sides of the cover plate, the position of the board can be initially determined before placing the board on the support plate. This facilitates the placement of the board and ensures that the board is centered on the support plate, preventing the hoisting device from shifting during hoisting.

[0041] 3. Construction safety: The second hook and wire rope allow the support plate and cover plate to clamp the sheet metal vertically, reducing slippage. Limiting rods inserted into the support plate and cover plate stop the sheet metal around its circumference, preventing slippage and ensuring safe hoisting. A limiting block at the bottom of the limiting rod inserts into the stop groove to cooperate with the support plate vertically. Simultaneously, the limiting block and the fastening nut together secure the support plate, sheet metal, and cover plate, ensuring the limiting rod's position remains unchanged during hoisting and guaranteeing hoisting safety.

[0042] The embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention.
