Description

Technical Field

[0001] This application belongs to the technical field of hoisting auxiliary equipment, specifically relating to an ALC wall panel auxiliary hoisting steel frame. Background Technology

[0002] ALC (autoclaved aerated concrete) partition wall panels are made from fly ash, cement, lime and other main raw materials, and are cured by high-pressure steam. They have excellent properties such as lightweight, fire resistance, sound insulation and environmental protection, and are widely used as wall materials in prefabricated buildings.

[0003] During the construction of ALC wall panels, lifting equipment is usually used for hoisting. The traditional hoisting method involves binding the ALC wall panels with nylon slings, and then connecting the hoisting part of the lifting equipment to the nylon slings to hoist the ALC wall panels.

[0004] However, when using nylon slings for hoisting, the nylon slings must first be tied to the ALC wall panel before hoisting can be carried out; after the ALC wall panel is hoisted to the designated position, the tied nylon slings must be untied, and the above tying process takes a long time. Utility Model Content

[0005] This application provides an auxiliary hoisting steel frame for ALC wall panels, which aims to solve the problem that the hoisting of ALC wall panels by nylon slings in the prior art is time-consuming.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: A steel frame for auxiliary hoisting of ALC wall panels is provided, comprising: Two strip-shaped support steel plates are hinged together at the middle position; each of the support steel plates has a clamping steel plate fixedly connected to both ends, and the clamping steel plate at the top of the support steel plate is the hoisting position, and the clamping steel plate is used to press against the wall panel; The hoisting structure has a top for connecting to the hoisting part of the lifting equipment, and a bottom with two sets of connecting components. The two sets of connecting components correspond one-to-one with two clamping steel plates at the hoisting position, and the connecting components are connected to the corresponding clamping steel plates. During the hoisting of the wall panel, the hoisting structure is located directly above the wall panel; the connecting components provide a pulling force to the clamping steel plates at the hoisting position in the direction of the wall panel, so that the two opposing clamping steel plates can press against the wall panel.

[0007] In one possible implementation, the auxiliary hoisting steel frame further includes two connecting plates, which correspond one-to-one with two supporting steel plates. The connecting plates are arranged parallel to the corresponding supporting steel plates. The connecting plates are detachably connected to the clamping steel plates on the corresponding supporting steel plates.

[0008] In one possible implementation, the other end of the clamping steel plate has a connecting post with external threads; the connecting plate has a through hole for the connecting post to pass through, and the portion of the connecting post passing through the connecting plate is secured by a nut.

[0009] In one possible implementation, the clamping steel plate has lifting rings; The connecting component includes a hook and a wire rope connected to the hook, the hook being able to be hung on the lifting ring; or, the connecting component includes a hook and a chain connected to the hook, the hook being able to be hung on the lifting ring.

[0010] In one possible implementation, the clamping steel plate has a rubber layer at the location where it can abut against the wall panel, and the rubber layer can increase the friction between the steel plate and the wall panel.

[0011] In one possible implementation, an elastic element is connected between the two supporting steel plates, and the two clamping steel plates at the hoisting position can move closer to each other under the elastic force of the elastic element to clamp the wall panel.

[0012] In one possible implementation, the hoisting structure includes a hoisting frame, the top of which is connected to the hoisting portion of the lifting equipment; wherein, at least two hoisting points are provided on each of the clamping steel plates at the hoisting position, and the two hoisting points are spaced apart.

[0013] In one possible implementation, both of the supporting steel plates have through holes in their middle portions, and a hinge shaft is located in the middle portion of both supporting steel plates, the hinge shaft passing through the through holes in the middle portions of the two supporting steel plates. One end of the hinge shaft has a limiting plate that contacts the side of one of the supporting steel plates; the other end of the hinge shaft passes through two supporting steel plates, and the protruding part of the hinge shaft has an external thread that is threaded with the hinge shaft by a nut.

[0014] In one possible implementation, one end of the clamping steel plate is fixed to the supporting steel plate by welding.

[0015] In one possible implementation, the length of the clamping steel plate is greater than or equal to the width of the wall panel.

[0016] This application provides an ALC wall panel auxiliary hoisting steel frame. Compared with the prior art, before hoisting the wall panel, two supporting steel plates are rotated outward so that the distance between the two opposing clamping steel plates is greater than the thickness of the wall panel. Then, the two pairs of clamping steel plates are placed on the wall panel. The connecting components are connected to the two clamping steel plates at the hoisting position, and the wall panel is slowly hoisted. After the wall panel is separated from the ground, the connecting components can provide an oblique pulling force to the clamping steel plates at the hoisting position. On the one hand, this can play the role of hoisting the wall panel, and on the other hand, it can make the two opposing clamping steel plates have a tendency to rotate towards the wall panel, so that the two opposing clamping steel plates can clamp the wall panel tightly. During the hoisting process, the separation of the wall panel from the clamping steel plates can be reduced. With the above-mentioned settings of this application, the wall panel can be hoisted simply by clamping the wall panel with two pairs of clamping steel plates and then hoisting the clamping steel plates. Compared with the process of binding with nylon slings in the prior art, this application can save binding time. Attached Figure Description

[0019] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0020] Please refer to the following: Figures 1 to 6 This application describes an auxiliary hoisting steel frame for ALC wall panels. The auxiliary hoisting steel frame for ALC wall panels includes two strip-shaped support steel plates 1 and a hoisting structure 2. The two strip-shaped support steel plates 1 are hinged together at the middle position. Each support steel plate 1 has clamping steel plates 3 fixedly connected to both ends, with one end of the clamping steel plate 3 fixed to the support steel plate 1 by welding. The clamping steel plate 3 at the top of the support steel plate 1 is the hoisting position, used to press against the wall panel 4. The top of the hoisting structure 2 is used to connect to the hoisting part of the lifting equipment, and the bottom has two sets of connecting parts 5, each corresponding to one of the two clamping steel plates 3 at the hoisting position. When hoisting the wall panel 4, the hoisting structure 2 is located directly above the wall panel 4. The connecting parts 5 provide a pulling force to the clamping steel plates 3 at the hoisting position towards the wall panel 4, so that the two opposing clamping steel plates 3 can press against the wall panel 4.

[0021] This application provides an auxiliary hoisting steel frame for ALC wall panels 4. Compared with the prior art, before hoisting the wall panel 4, the two supporting steel plates 1 are rotated outward so that the distance between the two opposing clamping steel plates 3 is greater than the thickness of the wall panel 4. Then, the two pairs of clamping steel plates 3 are fitted onto the wall panel 4. The connecting parts 5 are connected to the two clamping steel plates 3 at the hoisting position respectively, and the wall panel 4 is slowly hoisted. After the wall panel 4 is separated from the ground, the connecting parts 5 can provide an oblique pulling force to the clamping steel plates 3 at the hoisting position, which can, on the one hand, provide... The wall panel 4 is lifted, and on the other hand, the two opposing clamping steel plates 3 tend to rotate towards the wall panel 4, so that the two opposing clamping steel plates 3 can clamp the wall panel 4 tightly. During the lifting process, the separation of the wall panel 4 from the clamping steel plates 3 can be reduced. With the above-mentioned settings of this application, the wall panel 4 can be lifted simply by clamping the wall panel 4 with two pairs of clamping steel plates 3 and then lifting the clamping steel plates 3. Compared with the process of binding with nylon slings in the prior art, this application can save binding time.

[0022] The hoisting structure 2 is fixed to the hoisting part of the lifting equipment. Two sets of connecting parts 5 are symmetrically arranged on the hoisting structure 2. When the two sets of connecting parts 5 hoist and clamp the steel plate 3, the connecting parts 5 provide an upward pulling force on the clamped steel plate 3. The direction of the pulling force is towards the middle position of the wall plate 4. Therefore, the pulling force of the connecting parts 5 on the clamped steel plate 3 can make the clamped steel plate 3 have a tendency to rotate towards the wall plate 4, thereby making the clamped steel plate 3 press against the wall plate 4.

[0023] The length of the clamping steel plate 3 is greater than or equal to the width of the wall panel 4. Therefore, when clamping the wall panel 4, the wall panel 4 can be located between the two clamping steel plates 3, ensuring that the center of gravity is between the two clamping steel plates 3 during hoisting. If the width of the wall panel 4 is greater than the length of the clamping steel plate 3, the center of gravity may be on the outside of the clamping steel plate 3 when clamping the wall panel 4. In this case, the wall panel 4 will be severely tilted, posing a significant safety hazard. Therefore, the length of the clamping steel plate 3 in this application must be greater than the width of the wall panel 4.

[0024] In some embodiments, such as Figures 1 to 6 As shown, the auxiliary hoisting steel frame also includes two connecting plates 6, which correspond one-to-one with two supporting steel plates 1. The connecting plates 6 are arranged parallel to the corresponding supporting steel plates 1. The connecting plates 6 are detachably connected to the clamping steel plates 3 on the corresponding supporting steel plates 1. The other end of the clamping steel plate 3 has a connecting post 31 with external threads. The connecting plate 6 has a through hole for the connecting post 31 to pass through, and the part of the connecting post 31 that passes through the connecting plate 6 is fixed by a nut 32. The two connecting plates 6 are staggered to the left and right.

[0025] To improve safety, when clamping the steel plate with clamping steel plate 3, the free end of clamping steel plate 3 is inserted into connecting plate 6 and fixed by nut 32, which can improve the overall connection strength.

[0026] By setting the connecting plate 6 to correspond one-to-one with the supporting steel plate 1, when the supporting steel plate 1 rotates around the hinge position, the connecting plate 6 and the corresponding supporting steel plate 1 remain relatively stationary and will not affect the rotation of the supporting steel plate 1.

[0027] After the clamping steel plate 3 is placed on the wall panel 4, the clamping steel plates 3 are positioned opposite each other on both sides of the wall panel 4; the connecting plate 6 is inserted and matched with the corresponding connecting post 31, and then the position of the connecting plate 6 is fixed by the nut 32; the operator can tighten the nut 32 into place with a power tool in just a few seconds. Compared with the process of the operator tying the nylon sling to the wall panel 4, the above method of this application can save the tying time.

[0028] In some embodiments, such as Figures 1 to 6 As shown, the clamping steel plate 3 has a lifting ring 33; the connecting component 5 includes a hook 51 and a wire rope 52 connected to the hook 51, and the hook 51 can be hung on the lifting ring 33; or, the connecting component 5 includes a hook 51 and a chain connected to the hook 51, and the hook 51 can be hung on the lifting ring 33.

[0029] The connecting component 5 can be a wire rope 52 or a chain, taking the wire rope 52 as an example; one end of the wire rope 52 is fixed to the hoisting structure 2, and the other end of the wire rope 52 is fixedly connected to the hook 51; after the clamping steel plate 3 is placed on the wall panel 4, the hook 51 is connected to the corresponding clamping steel plate 3 and hoisted upward; after the wall panel 4 leaves the ground, the oppositely arranged clamping steel plates 3 all have a tendency to rotate towards the middle of the wall panel 4, so the two oppositely arranged clamping steel plates 3 can clamp the wall panel 4.

[0030] In some embodiments, such as Figures 1 to 6 As shown, the clamping steel plate 3 has a rubber layer 34 at the position that can press against the wall panel 4, and the rubber layer 34 can increase the friction between the steel plate 3 and the wall panel 4.

[0031] The rubber layer 34 is wear-resistant and non-slip. During the process of clamping the wall panel 4, the steel plate 3 comes into contact with the wall panel 4 through the rubber layer 34, which can increase the friction and reduce the damage to the surface of the wall panel 4, thereby improving the clamping stability.

[0032] In some embodiments, such as Figures 1 to 6 As shown, an elastic element 7 connects the two supporting steel plates 1. The two clamping steel plates 3 at the hoisting position can move closer to each other under the elastic force of the elastic element 7 to clamp the wall panel 4. The elastic element 7 includes a tension spring, and the two ends of the tension spring are respectively connected to the two supporting steel plates 1. Among them, four areas are formed between the two supporting steel plates 1, and the area of ​​the supporting steel plate 1 at the hoisting position is the tension spring setting area. The two clamping steel plates 3 at the hoisting position can move closer to each other under the elastic force of the tension spring.

[0033] The tension spring has hooks at both ends, and the support steel plate 1 has through holes for connecting the hooks. The hooks on the tension spring are hung on the through holes on the support steel plate 1. The tension spring provides elastic force to the two support steel plates 1, which enables the two clamping steel plates 3 arranged opposite to each other to move closer to each other. When the wall panel 4 is placed between the two clamping steel plates 3, the two clamping steel plates 3 can pre-clamp the wall panel 4 under the elastic force of the tension spring.

[0034] The tension spring has two functions: First, when the operator rotates the support steel plate 1 outward, the tension spring provides tension to the two support steel plates 1. When the operator removes the external force of rotation, the two support steel plates 1 can rotate inward and reset under the tension of the tension spring. Second, during the clamping of the wall panel 4, the tension of the tension spring on the two support steel plates 1 enables the two clamping steel plates 3 to provide an initial clamping force on the wall panel 4.

[0035] When the tension spring is compressed to its minimum position, the length of the extendable part of the tension spring is less than the thickness of the wall panel 4. Therefore, when the clamping steel plate 3 clamps the wall panel 4, the tension spring is not compressed to its minimum position. The tension spring still provides tension to the two supporting steel plates 1, thereby causing the two clamping steel plates 3 to apply clamping force to the wall panel 4.

[0036] In some embodiments, such as Figures 1 to 6 As shown, the hoisting structure 2 includes a hoisting frame, the top of which is fixedly connected to the hoisting part of the lifting equipment; wherein, each clamping steel plate 3 at the hoisting position has at least two hoisting points, and the two hoisting points are spaced apart.

[0037] Both supporting steel plates 1 have clamping steel plates 3 at their top and bottom. Therefore, the clamping steel plates 3 at the top of the two supporting steel plates 1 are upper clamping components, and the clamping steel plates 3 at the bottom of the two supporting steel plates 1 are lower clamping components.

[0038] In actual use, the upper clamping component and the lower clamping component are exactly the same. Therefore, the upper clamping component can be placed on top and the lower clamping component can be placed on the bottom, or the upper clamping component can be placed on the bottom and the lower clamping component can be placed on top. In any case, the hoisting structure 2 hoists the two clamping steel plates 3 located on the top.

[0039] Taking two lifting points as an example, each clamping steel plate 3 has two lifting points, which can balance the overall lifting position during lifting and make the lifting process more stable.

[0040] In some embodiments, such as Figures 1 to 6 As shown, both supporting steel plates 1 have through holes in their middle sections, and a hinge shaft 8 is located in the middle of both supporting steel plates 1. The hinge shaft 8 passes through the through holes in the middle of both supporting steel plates 1. One end of the hinge shaft 8 has a limiting plate 81, which contacts the side of one of the supporting steel plates 1. The other end of the hinge shaft 8 passes through both supporting steel plates 1, and the protruding part of the hinge shaft 8 has external threads, which are threaded together with the hinge shaft 8 by a nut 32.

[0041] By setting a limiting plate 81 at one end of the hinge shaft 8 and setting an external thread on the outer peripheral wall of the other end of the hinge shaft 8, the limiting plate 81 can play a limiting role after the hinge shaft 8 passes through the two supporting steel plates 1; by threading the nut 32 with the other end of the hinge shaft 8, the hinge shaft 8 can be axially limited, reducing the possibility of the hinge shaft 8 falling off the supporting steel plate 1.

[0042] Nut 32 is a lock nut to reduce the possibility of nut 32 falling off the hinge shaft 8; after nut 32 is tightened to the position, nut 32 will not press against the support steel plate 1, so nut 32 will not affect the rotation of the two support steel plates 1.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
