Description

Technical Field

[0001] This utility model belongs to the technical field of building hoisting equipment, specifically relating to an auxiliary device for hoisting and flipping prefabricated exterior wall panels. Background Technology

[0002] With the development and increasing demands for energy conservation, emission reduction, and residential industrialization in buildings, prefabricated buildings will become an inevitable trend in my country's construction industry. In the construction process of prefabricated buildings, the hoisting of prefabricated components is a crucial step that runs through all stages. For example, the hoisting of prefabricated exterior wall panels, especially those with decorative outer surfaces, mainly employs the following two hoisting methods: With the prefabricated exterior wall panel facing upwards, it is directly flipped and lifted by end hoisting iron parts, with one end grounded. However, during the hoisting process, the grounded end of the prefabricated exterior wall panel rubs against the ground, which can easily cause problems such as chipping and damage at the end of the prefabricated exterior wall panel. With the prefabricated exterior wall panel facing downwards, it is horizontally lifted using bottom demolding iron parts and end hoisting iron parts. Then, based on the cooperation of the demolding iron part hoisting rope and the hoisting iron part hoisting rope, the prefabricated exterior wall panel is flipped in the air. Although this avoids ground damage to the end of the prefabricated exterior wall panel, if the surface of the prefabricated exterior wall panel facing downwards is worn, it is difficult to repair it on the hoisting construction site. In summary, this application provides a hoisting and flipping auxiliary device that can ensure the prefabricated exterior wall panel faces upward and avoid grounding damage to the ends of the prefabricated exterior wall panel. Summary of the Invention

[0003] In view of this, in order to solve the problems mentioned in the background art, the purpose of this utility model is to provide an auxiliary device for hoisting and turning prefabricated exterior wall panels.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A prefabricated exterior wall panel hoisting and tilting auxiliary device includes: Support base; A flip plate, hinged to the top of the support base, includes a base plate and a side pressure plate that can rotate relative to the base plate, so as to form a limiting space between the base plate and the side pressure plate that can abut and clamp the end of the prefabricated exterior wall panel. A limiting mechanism connects the base plate and the side pressure plate, and prevents the side pressure plate from rotating after it abuts against the end of the prefabricated exterior wall panel.

[0005] Preferably, the substrate has an open arc groove near its end, and the side pressure plate has a connecting post near its end that rotatably engages with the open arc groove.

[0008] Preferably, the distal end of the substrate is bent to form a balancing support portion, the balancing support portion including a support foot and a connecting plate connecting the support foot and the substrate.

[0009] Preferably, a plurality of flexible pressure strips are arranged side by side on the inner side of the side pressure plate, and the flexible pressure strips extend along the width direction of the side pressure plate.

[0010] Preferably, the limiting mechanism includes a reinforcing connecting plate fixed to the near end of the substrate and a connecting rod rotatably connected to the reinforcing connecting plate, wherein the connecting rod is provided with a pressure plate that can abut against and press against the side pressure plate.

It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so as to the embodiments of this application described herein.

[0019] like Figure 1As shown, the present invention provides a prefabricated exterior wall panel hoisting and tilting auxiliary device, comprising a support base 1, a tilting plate 2, and a limiting mechanism 3. Specifically, the support base 1 is composed of at least one support beam, and the tilting plate 2 is hinged to the top of the support base 1 via a hinge joint, so that the tilting plate 2 can be tilted relative to the support base 1 from a horizontal state to a vertical state. It is worth noting that the hinge joint consists of an upper connector, a lower connector, and a rotating shaft; the upper connector is welded to the tilting plate 2, and the lower connector is welded to or bolted to the support base 1.

[0020] For example, when hoisting and flipping prefabricated exterior wall panels, based on Figure 6 The horizontal hoisting shown allows the left end of the precast exterior wall panel to overlap the flipping plate 2. Then, the right end of the precast exterior wall panel is hoisted, and the precast exterior wall panel and the flipping plate 2 flip simultaneously. The flipping plate 2 and the limiting mechanism 3 work together to fix the precast exterior wall panel, so that the left end of the precast exterior wall panel and the flipping plate 2 remain relatively stationary, thereby effectively avoiding damage to the precast exterior wall panel during the hoisting and flipping process.

[0021] In one specific embodiment, the flip plate 2 includes as follows: Figure 3 The diagram shows a substrate 21 and a side pressure plate 22 that can rotate relative to the substrate 21. Specifically, in the initial state, the flip plate 2 keeps the side pressure plate 22 perpendicular to the substrate 21. When the prefabricated exterior wall panel is horizontally hoisted and overlapped on the flip plate 2, the end of the prefabricated exterior wall panel is supported on the top of the substrate 21. However, due to the influence of the crane's manual operation during hoisting, it is difficult to ensure that the left end of the prefabricated exterior wall panel always lands in the same position on the substrate 21. That is, during repeated hoisting, gaps of different sizes may form between each prefabricated exterior wall panel and the near end of the substrate 21. In order to compensate for this gap and ensure that the flip plate 2 can effectively protect the left end of the prefabricated exterior wall panel, the side pressure plate 22 is rotated to form a limiting space between the substrate 21 and the side pressure plate 22 that can abut and clamp the end of the prefabricated exterior wall panel.

[0022] It is worth noting that multiple flexible pressure strips 221 are arranged side by side on the inner side of the side pressure plate 22. The flexible pressure strips 221 extend along the width direction of the side pressure plate 22. On the one hand, this prevents the side pressure plate 22 from pressing the prefabricated exterior wall panel and damaging the wall panel finish. On the other hand, it prevents the prefabricated exterior wall panel from shifting along the length direction of the side pressure plate 22 during the flipping process. This allows the flipping plate 2 to be adapted to prefabricated exterior wall panels that are longer than itself, meaning that the size of the prefabricated exterior wall panel is not limited by the size of the flipping plate 2.

[0023] In this embodiment, as Figure 3As shown, the substrate 21 has an open arc groove 23 near its proximal end, and a plurality of rotatable open rings 231 are uniformly embedded in the open arc groove 23. A connecting post 24 is integrally formed near the proximal end of the side pressure plate 22. The connecting post 24 is inserted and fixed into the open rings 231, and the side pressure plate 22 extends out from the opening of the open rings 231, thereby achieving a rotatable connection between the side pressure plate 22 and the substrate 21. Specifically, the opening arc of the open arc groove 23 is not less than 90°, while ensuring that the opening size of the open rings 231 is smaller than the opening size of the open arc groove 23. This ensures that the side pressure plate 22 can rotate at least 90° relative to the substrate 21, and that during the rotation of the side pressure plate 22 and the open rings 231, the open rings 231 are at least partially exposed outside the open arc groove 23. Figure 4 The open ring 231 structure shown has connecting portions at both ends. Rotation of the open ring 231 allows one end to be fully exposed outside the open arc groove 23. The connecting portion has a screw hole for assembly with the connecting post 24, thereby fixing the connecting post 24 and the connecting portion with bolts, thus securing the side pressure plate 22 to the open ring 231. Conversely, the side pressure plate 22 can be disassembled and replaced by removing the bolts from the connecting portion.

[0024] It is worth noting that, in order to ensure the stability of the rotational connection between the side pressure plate 22 and the base plate 21, a dovetail groove 232 is provided on the surface of the opening ring 231 to prevent the opening ring 231 from disengaging from the opening arc groove 23. Correspondingly, the opening arc groove 23 is provided with a mating groove that is adapted to the opening ring 231 and the dovetail groove 232.

[0025] Furthermore, it should be noted that the distal end of the substrate 21 is bent to form a balancing support portion, which includes a support leg 211 and a connecting plate 212 connecting the support leg 211 and the substrate 21. Specifically, refer to... Figure 5 As shown in the structure, the connecting plate 212 is formed by bending the distal end of the base plate 21 downwards, and the supporting leg 211 is formed by bending the bottom of the connecting plate 212 horizontally, extending away from the base plate 21, with a rounded transition at the bend. When the flip plate 2 is flipped to a horizontal state, the supporting leg 211 rests on the ground, thereby ensuring the stability of the flip plate 2 when flipped to a horizontal state, that is, ensuring the prefabricated exterior wall panel... Figure 6 When the panel is attached to the base plate 21 in the manner shown, the base plate 21 can stably support the prefabricated exterior wall panel in a horizontal state. Optionally, to further improve the structural strength of the balancing support, reinforcing ribs can be fixed between the support leg 211 and the connecting plate 212, and between the connecting plate 212 and the base plate 21.

[0026] In one specific embodiment, the limiting mechanism 3 includes, as follows: Figure 1 and Figure 2 The pressure plate 31, connecting rod 32, and reinforcing connecting plate 33 are shown. Specifically, the reinforcing connecting plate 33 is shaped as follows: Figure 5 The L-shaped structure shown has the base plate 21 fixed to the inner corner of the L-shaped structure near its proximal end, thereby limiting the side pressure plate 22 while strengthening the rotatable connection between the side pressure plate 22 and the base plate 21. A shaft is provided through the reinforcing connecting plate 33, and a bushing is fixed to one end of the connecting rod 32. The bushing is rotatably sleeved on the shaft, so that the connecting rod 32 is rotatably mounted on the reinforcing connecting plate 33. The connecting rod 32 passes through the pressure plate 31, and at least part of the connecting rod 32 is a threaded rod structure. A nut 34 is screwed onto the connecting rod 32 to abut against the pressure plate 31.

[0027] For example, after the side pressure plate 22 is rotated and pressed against the end of the prefabricated exterior wall panel, the connecting rod 32 is rotated so that the connecting rod 32 faces the side pressure plate 22, and the pressure plate 31 on the connecting rod 32 is moved so that the pressure plate 31 presses against the side pressure plate 22. Then, the nut 34 is rotated so that the nut 34 presses against the pressure plate 31, thereby limiting the position of the side pressure plate 22 and ensuring the stable clamping of the end of the prefabricated exterior wall panel by the flipping plate 2. Specifically, the side pressure plate 22, after being limited, is located between the pressure plate 31 and the prefabricated exterior wall panel, and the side pressure plate 22, the base plate 21, the connecting rod 32 and the reinforcing connecting plate 33 are combined to form a triangular support structure. Under this structure, the stable clamping of the end of the prefabricated exterior wall panel is limited between the side pressure plate 22 and the base plate 21, thereby ensuring that the flipping plate 2 and the prefabricated exterior wall panel can be flipped synchronously. At the same time, it also ensures the stable support of the side pressure plate 22 for the prefabricated exterior wall panel during the flipping process.

[0028] Preferably, to further enhance the support strength of the reinforcing connecting plate 33 for the connecting rod 32, a reinforcing rib is fixed at least inside the reinforcing connecting plate 33. The reinforcing rib has a triangular structure, and the two right-angled sides of the triangular structure are respectively disposed on the reinforcing connecting plate 33 and the base plate 21.

[0029] It is worth noting that the pressure plate 31 includes, for example, Figure 2 The diagram shows a main board body 311 and an inverted U-shaped limiting plate 312 extending from the side edge of the main board body 311. A connecting rod 32 passes through the inverted U-shaped limiting plate 312, and a nut 34 is confined within the slot of the inverted U-shaped limiting plate 312, thereby ensuring that the pressure plate 31 is confined to the position of the nut 34. Specifically, the inverted U-shaped limiting plate 312 includes a long arm plate and a short arm plate, and the connecting rod 32 at least passes through the long arm plate, thus making the tightening operation of the nut 34 more convenient.
