Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a hoisting frame. Background Technology

[0002] Tower cranes are widely used in the construction industry for lifting objects. Please refer to [reference needed]. Figure 1 Currently, the hoisting frame is simply assembled with disc buckles and the object to be hoisted is placed directly inside. The objects to be hoisted include: standard bricks, perforated bricks, aerated concrete blocks, disc buckle connectors and other loose materials. These objects are not easy to fix. During the hoisting process, if the hoisting frame tilts, the hoisted object is easy to fall off, causing frequent hoisting accidents. Furthermore, when the object is hoisted and unloaded, it is easy for the object to scatter. The scattered object is inconvenient to clean up, which directly affects the efficiency of hoisting and transportation, and thus affects the progress of the project.

[0003] In view of the shortcomings of existing hoisting frames, those skilled in the art have been searching for solutions. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting frame that can eliminate safety hazards when lifting loose materials and effectively improve the efficiency of lifting and transportation.

[0005] To solve the above-mentioned technical problems, this utility model provides a hoisting frame, comprising: a frame; a base plate and four side plates for semi-enclosed frame; four three-sided fastening connectors respectively disposed at the bottom inner corners of the frame for fixing the base plate, side plates and frame together; and multiple lifting points disposed on the frame. Optionally, in the hoisting frame, each three-sided fastening connector includes: three sector plates and bolt holes formed on each sector plate, the three sector plates being welded perpendicularly to each other and forming a right angle together. Optionally, in the hoisting frame, each sector plate is a quarter-circle plate with a radius of 100mm. Optionally, in the hoisting frame, each side of each three-sided fastening connector is fixedly connected to the base plate and two side plates by a bolt. Optionally, in the hoisting frame, the base plate and the side plates are both circular perforated plates. Optionally, in the hoisting frame, the diameter of the circular perforations on the circular perforated plates is 22mm. Optionally, in the hoisting frame, the frame includes: eight horizontal bars, four vertical bars, and two vertical discs sleeved and fixed to each vertical bar. The eight horizontal bars and four vertical bars together form a cuboid frame. The two ends of each horizontal bar are respectively inserted and fixed to the two vertical discs at corresponding positions, indirectly fixing the horizontal bars and vertical bars. The upper lifting point is located on the vertical disc. Optionally, in the hoisting frame, the upper lifting point is only located on the vertical disc at the upper end of the frame. Optionally, in the hoisting frame, the upper lifting point is a lug-type upper lifting point. Optionally, in the hoisting frame, each lug-type upper lifting point includes: a base and a plate-type lifting lug vertically fixed to the base.

[0006] The hoisting frame provided by this utility model includes: a frame; a base plate and four side plates for a semi-enclosed frame; four three-sided fastening connectors, respectively located at the bottom inner corners of the frame, for fixing the base plate, side plates, and frame together; and multiple lifting points located on the frame. Based on the structural design of the hoisting frame, the base plate, side plates, and frame are fixedly connected by the three-sided fastening connectors to form a semi-enclosed hoisting frame, thereby creating a space to accommodate the hoisted object, effectively limiting the movement space of the hoisted object, preventing the hoisting frame from tilting, and avoiding the possibility of the hoisted object falling off, thus preventing hoisting accidents. In addition, when hoisting objects using the hoisting frame of this utility model, the objects are neatly arranged and not scattered when unloading, making them easy to clean up, improving the efficiency of hoisting and transportation, and thus improving the progress of the project. Furthermore, the three-sided fastening connectors are versatile and can be matched with base plates, side plates, and uprights of different sizes to easily meet the actual conditions and needs of on-site hoisting construction. On the other hand, using circular perforated plates as the bottom plate and sides of the hoisting frame reduces the weight of the hoisting frame while also serving a drainage function to cope with the harsh environment and complex weather at the construction site.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the utility model according to the specific circumstances.

[0020] Please refer to Figures 1 to 5 The hoisting frame 100 includes: a frame 101; a base plate and four side plates for semi-enclosing the frame 101; four three-sided fastening connectors 103, respectively disposed at the bottom inner corners of the frame 101, for fixing the base plate, side plates, and frame 101 together; and multiple lifting points 104 disposed on the frame 101. Please refer to... Figure 4 and Figure 5 Each three-sided fastening connector 103 includes three sector-shaped plates and bolt holes on each sector plate. The three sector plates are welded perpendicularly to each other and together form a right angle. In this embodiment, each sector plate is a quarter-circle plate with a radius of 100mm. Each side of each three-sided fastening connector 103 is fixedly connected to the base plate and the two side plates by a bolt. Through the connection method of the three-sided fastening connector 103, it can be matched with circular perforated plates 102 and uprights 105 of different sizes, which can easily meet the actual site conditions and needs, and has versatility.

[0021] Specifically, the bolt penetration sequence on the side of the three-sided fastening connector 103 located on the base plate 102 is as follows: from top to bottom, the bolts penetrate the bottom side of the three-sided fastening connector 103 -> base plate 102 -> upright disc 107. That is, the bottom side of the three-sided fastening connector 103 is fixed to the upright disc 107 by bolts, indirectly fixing the relative positions of the three-sided fastening connector 103 and the base plate 102. Preferably, the bolts are M6 bolts, and correspondingly, bolt holes adapted for M6 bolts are opened on each side of the three-sided fastening connector 103.

[0022] Furthermore, such as Figure 1 and Figure 5As shown, both the base plate and the side plate are circular perforated plates 102. The diameter of the circular perforations on the circular perforated plates is preferably 22mm. It can be understood that the diameter of the circular perforations is not limited to 22mm, as long as it can ensure the safe hoisting of loose materials. Here, opening circular holes on the base plate and the sides not only achieves weight reduction (reducing the weight of the base plate and side plates), but also serves a drainage function to cope with the harsh environment and complex weather of the construction site.

[0023] Preferably, the surface of the circular perforated plate 102 can be galvanized, which not only improves the appearance but also provides rust prevention, thereby increasing the service life of the circular perforated plate 102.

[0024] like Figure 1 As shown, the frame 101 includes eight horizontal rods 106, four vertical rods 105, and two vertical rod discs 107 fixedly attached to each vertical rod. The eight horizontal rods 106 and four vertical rods 105 together form a cuboid frame. Each horizontal rod 106 has its two ends inserted and fixed to the two vertical rod discs 107 at corresponding positions, indirectly connecting the horizontal rods 106 and the vertical rods 105. The upper suspension point is located on the vertical rod disc 107. Specifically, the upper suspension point is only located on the vertical rod disc 107 at the upper end of the frame 101.

[0025] Specifically, the frame 101 can be assembled by using scaffolding materials and connecting and fastening them with bolts. The entire assembly process is convenient and requires no additional customized preparation. In this embodiment, the parameters of each component of the hoisting frame are as follows: each sector plate of each three-sided fastening connector 103 is a quarter-circle plate with a radius of 100mm; the upright 105 has a diameter of 48mm, a wall thickness of 3.2mm, and five lengths of 500mm, 1000mm, 1500mm, 2000mm, and 2500mm, which can be assembled as needed; the horizontal bar 106 has a length of 900mm, a diameter of 48mm, and a wall thickness of 2.5mm; the outer diameter of the upright disc 107 is 122mm, and the inner diameter is 48mm. In this embodiment, the upper hoisting point 104 is an ear-plate type upper hoisting point. Specifically, as... Figure 6 As shown, each ear-plate type lifting point includes a base and a plate-type lifting lug vertically fixed to the base. The base has two symmetrically arranged M6 bolt holes on its left and right sides. The lifting point 104 is fixed to the upright disc 107 by passing M6 bolts through these M6 bolt holes. Furthermore, the plate-type lifting lug has M15 holes for easy threading of the wire rope. To ensure that the lifting points and connecting parts (including bolts and three-sided fasteners) of the lifting frame designed in this utility model can withstand the force under the rated load, and to ensure that the dimensions of the lifting points and connecting parts meet the force requirements, the dimensions and requirements of the lifting points and connecting parts are designed through calculation of the following parameters.

[0026] Here, we take an example where the total weight of the lifting points, including the plate-type lifting lugs, the frame, one base plate, and four side plates is approximately 150kg. The details are as follows:

[0027] 1) Tensile strength calculation of plate-type lifting lugs:

[0028] σ=F / (n*t*d)=(2+0.15) / (3*5*10)=143.33N / mm 2 ≤f 耳 =205 N / mm 2

[0029] n: The number of wire ropes is taken as 3 under the most unfavorable working condition;

[0030] t: The thickness of the lifting lug plate is 10mm;

[0031] d: The distance from the lifting lug hole to the edge of the lifting lug is 5mm;

[0032] The material for the plate-type lifting lugs is Q235;

[0033] The angle between the wire rope and the horizontal is 90°.

[0034] 2) Tensile strength calculation of M6 bolts for plate lifting lugs:

[0035] N=F / (n*n1πd1 2 / 4)=2.15 / (3*2*π*6 2 / 4)=126.80N / mm 2 ≤f 拉 =210N / mm 2

[0036] n: The number of wire ropes is taken as 3 under the most unfavorable working condition;

[0037] n1: The number of bolts for a single plate lifting lug is 2;

[0038] The angle between the wire rope and the horizontal is 90°.

[0039] 3) Shear calculation of M6 bolts connecting the three-sided fasteners to the side plate:

[0040] τ=F / (n2*n3*πd1 2 / 4)=2.15 / (4*2*π*6 2 / 4)=95.02N / mm 2 ≤f 剪 =190N / mm 2

[0041] n2: The number of three-sided fastening connectors is 4;

[0042] n3: The number of shear bolts in a single three-sided fastening connector is 2;

[0043] 4) Tensile strength calculation of M6 bolts connecting the three-sided fasteners to the base plate:

[0044] N=F / (n2*n4πd1 2 / 4)=2.15 / (4*1*π*6 2 / 4)=190.1N / mm 2 ≤f 拉 =210N / mm 2

[0045] n2: The number of three-sided fastening connectors is 4;

[0046] n4: The number of tension bolts in a single three-sided fastening connector is 1.

[0047] Calculations show that, assuming the diameter of the circular perforations on the perforated plate is 22mm, there are 1106 perforations, and the plate thickness is 5mm, the volume of the perforated plate, multiplied by the density of iron, yields a maximum mass of 20kg for a single plate. Assuming a side length of 0.978mm, the cube of the side length gives a maximum capacity of 0.93m³ for the lifting frame. 3 The final calculation, rounded down, yields a lifting frame with a load capacity of up to 2 tons. Therefore, the lifting frame designed in this invention is characterized by convenient assembly and disassembly, low cost, light weight (maximum weight of a single circular perforated plate is 20 kg), and large capacity (maximum 0.93 m³). 3 It has advantages such as high load capacity (2t).

[0048] This utility model has at least the following beneficial effects:

[0049] 1) Based on the structural design of the hoisting frame, the bottom plate, side plates and frame are fixedly connected by three-sided fastening connectors to form a semi-enclosed hoisting frame, thereby creating a space to accommodate the hoisted object, effectively limiting the movement space of the hoisted object, avoiding tilting of the hoisting frame, and preventing the hoisted object from falling off and causing hoisting accidents; in addition, based on the hoisting frame of this utility model, when hoisting objects, the objects are neat and not scattered when unloading, which is convenient for handling, improving the efficiency of hoisting and transportation, and thus improving the progress of the project.

[0050] 2) The three-sided fastening connectors are versatile and can be matched with base plates, sides, and uprights of different sizes to easily meet the actual conditions and needs of on-site hoisting construction. 3) Circular perforated plates are used as the base plate and sides of the hoisting frame, which reduces the weight of the hoisting frame while also serving a drainage function to cope with the harsh environment and complex weather of the construction site.
