[0023] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0024] As Figures 1 to 5 shown, the utility model provides a novel turnover spreader, including inverted U type hanger 3, install the turnover frame 2 who can overturn relative to inverted U type hanger 3 in inverted U type hanger 3 bottom surface opening, specifically, with Figure 1 Example, the left and right direction of turnover frame 2 is the length direction of turnover frame 2, and the bottom both sides of the length direction of turnover frame 2 are connected with inverted U type hanger 3 through swing support and rotate, and driving device 5 is installed on inverted U type hanger 3 on turnover frame 2, and driving device 5 is prior art, can drive turnover frame 2 to overturn in inverted U type hanger 3, the top of turnover frame 2 is installed with the lifting assembly 1 of horizontal arrangement, and the lifting assembly 1 includes the bracket structure 11 of horizontal arrangement and strip shape, both ends of bracket structure 11 are installed with pulley assembly 12, and the axial line of pulley assembly 12 is parallel with the width direction of bracket structure 11, and the projection of two pulley assemblies 12 in vertical direction is located on a straight line parallel with the length direction of bracket structure 11, specifically, pulley assembly 12 all includes pulley shaft 121 parallel with the width direction of bracket structure 11, and both ends of pulley shaft 121 are connected with bracket structure 11, and pulley shaft 121 all coaxially line sleeve pulley 122 on, and each pulley assembly 12 close to the length direction of bracket structure 11 one side still all be provided with electric telescopic rod 13, to Figure 2 Example, electric telescopic rod 13 is located on the back side or front side of pulley assembly 12, electric telescopic rod 13 can be provided as hydraulic oil cylinder, electric telescopic rod 13 all are horizontally installed on bracket structure 11 and can synchronous telescopic, and the telescopic end of two electric telescopic rods 13 respectively one to one towards pulley assembly 12 and be diagonally arranged with pulley assembly 12, and the telescopic end of each electric telescopic rod 13 and diagonally arranged pulley assembly 12 all are provided with wire rope 14, and one end of wire rope 14 away from electric telescopic rod 13 is installed with lifting piece 15 after passing pulley assembly 12, specifically, wire rope 14 passes pulley 122 from the top of pulley 122, and lifting piece 15 can be provided as lifting hook or lifting ring, and is located below bracket structure 11.
[0025] In use, the lifting member 15 can be lifted or lowered by the steel wire 14 through the extension or retraction of the electric telescopic rod 13. Since the projections of the two sets of pulley assemblies 12 in the vertical direction are located on a straight line parallel to the length direction of the support structure 11, the two lifting members 15 are symmetrically distributed at the two ends of the support structure 11, so that the two symmetrically distributed lifting points of the heavy object can be lifted by the two lifting members 15 respectively. Then, when the heavy object is lifted, the two lifting members 15 can be lifted synchronously by the synchronous retraction of the extension ends of the two electric telescopic rods 13, so as to prevent the heavy object from being inclined. Since the electric telescopic rods 13 are horizontally distributed, and the steel wires 14 are installed between the extension ends of the electric telescopic rods 13 and the lifting members 15, the extension ends of the electric telescopic rods 13 do not occupy space in the vertical direction after being retracted, so that the height of the heavy object lifted can be increased, so that the heavy object has sufficient height in the turnover frame 2, and the heavy object can be turned over when the turnover frame 2 is turned over.
[0026] Further, as shown in Figure 1 and Figure 2 , one of the two sets of pulley assemblies 12 is higher than the other set of pulley assemblies 12, the two electric telescopic rods 13 are located on the same side of the pulley assemblies 12, and the two electric telescopic rods 13 are respectively a first electric telescopic rod 131 and a second electric telescopic rod 132. The second electric telescopic rod 132 is higher than the first electric telescopic rod 131, and the extension end of the second electric telescopic rod 132 is diagonally arranged with the pulley assembly 12 located at the higher position. The extension end of the first electric telescopic rod 131 is diagonally arranged with the pulley assembly 12 located at the lower position, so that the extension ends of the two electric telescopic rods 13 do not interfere with each other when synchronously extended or retracted. Since the two electric telescopic rods 13 are located on the same side of the pulley assemblies 12, the width of the support structure 11 can be reduced. The steel wire 14 connected to the extension end of the first electric telescopic rod 131 is shorter than the other set of steel wires 14, and the length difference between the two sets of steel wires 14 is adapted to the height difference between the two sets of pulley assemblies 12. In use, the two lifting members 15 can be lifted synchronously by the synchronous retraction of the extension ends of the two electric telescopic rods 13, so as to prevent the heavy object from being inclined.
[0027] The specific arrangement of the electric telescopic rod 13 horizontally installed on the support structure 11 is as follows: as shown in Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the ends of the electric telescopic rod 13 away from the steel wire rope 14 are respectively hinged to the ends of the support structure 11 through the hinge shaft 19, the hinge shaft 19 is vertically distributed, and the two ends of the hinge shaft 19 are respectively connected with the support structure 11. Specifically, since the hinge shaft 19 is vertically distributed, the downward inclination range of the electric telescopic rod 13 in the horizontal state can be limited to ensure that the electric telescopic rod 13 can normally extend and retract. Alternatively, a support ring for supporting the rod barrel of the electric telescopic rod 13 can be installed on the support structure 11, the inner diameter of the support ring is greater than the outer diameter of the rod barrel of the electric telescopic rod 13, so as to limit the downward inclination of the electric telescopic rod 13. Secondly, since the end of the electric telescopic rod 13 away from the steel wire rope 14 is hinged to the end of the support structure 11, the electric telescopic rod 13 has sufficient extension length.
[0028] The specific arrangement mode that the steel wire rope 14 is connected with the telescopic end of the electric telescopic rod 13 is as follows: Figure 1 And Figure 2 As shown, the telescopic end of the electric telescopic rod 13 is provided with a U-shaped opening U-shaped frame 16 away from the electric telescopic rod 13, and the U-shaped frame 16 is provided with a detachable pin shaft 17. The end of the steel wire rope 14 close to the electric telescopic rod 13 is respectively sleeved on the pin shaft 17 through a steel wire rope buckle. Specifically, the steel wire rope buckle is a prior art, and when installing, the steel wire rope buckle is first placed in the U-shaped frame 16, then the pin shaft 17 is sequentially inserted through the U-shaped frame 16 and the steel wire rope buckle, and then a split pin is installed on the pin shaft 17 to install the pin shaft 17 on the U-shaped frame 16. In this way, during use, the steel wire rope 14 can be conveniently disassembled and assembled at the telescopic end of the electric telescopic rod 13.
[0029] Further, as shown in Figure 3 And Figure 4 As shown, the number of the lifting assembly 1 is two groups, and the two groups of lifting assemblies 1 are symmetrically arranged on the top of the turnover frame 2. In this way, during use, the four lifting pieces 15 of the two groups of lifting assemblies 1 can be selected to hoist the heavy object according to the needs, and the four lifting pieces 15 of the two groups of lifting assemblies 1 can be synchronously lifted to stabilize the hoisting of the heavy object.
[0030] Further, as shown in Figure 1 And Figure 3 As shown, the four lifting pieces 15 of the two groups of lifting assemblies 1 are provided with a lifting tool 4 capable of lifting in the turnover frame 2. Specifically, during use, the corresponding lifting tool can be set according to the different hoisted heavy objects. At this time, the stability of the lifting tool 4 during lifting can be improved during the synchronous lifting of the four lifting pieces 15 of the two groups of lifting assemblies 1, so as to conveniently lift the heavy object into the turnover frame 2.
[0031] Further, as shown in Figure 1 And Figure 3As shown, the spreader 4 includes a horizontally arranged transverse frame 41, which is a rectangular frame. The four corners of the top surface of the transverse frame 41 are connected to the lifting components 15 respectively. The four corners of the transverse frame 41 are also equipped with hydraulic opening and closing mechanisms 42. Specifically, the hydraulic opening and closing mechanism 42 is existing technology, and its structure is the same as that of the hydraulic opening and closing mechanism used for lifting containers in the prior art. In use, the spreader 4 can be used to lift the container, and under the action of the lifting assembly 1, the container can be lifted into the tilting frame 2 to facilitate the tilting operation of the container.
[0032] The specific setup method for flipping frame 2 is as follows: Figure 1 , Figure 3 and Figure 4 As shown, the tilting frame 2 includes a horizontally arranged first top frame 21. Two vertically opposite first side frames 22 are installed at both ends of the first top frame 21. The bottoms of the first side frames 22 are rotatably connected to the inverted U-shaped hanger 3. Two oppositely arranged and spaced crossbeams 23 are installed between the two first side frames 22. The crossbeams 23 are parallel to the length direction of the first top frame 21, and the crossbeams 23 can improve the structural stability of the tilting frame 2. Both sets of lifting assemblies 1 are installed on the first top frame 21 and are parallel to the length direction of the first top frame 21. Specifically, when a heavy object is tilted within the tilting frame 2, the crossbeams 23 can support the heavy object. Furthermore, with... Figure 3 For example, the two crossbeams 23 are located on the outside of the two sides of the tilting frame 2, so that when the heavy object enters or exits the tilting frame 2 during the lifting process, the crossbeams 23 will not affect the lifting of the heavy object; secondly, when the heavy object is tilted to a downward distribution, such as when lifting some storage boxes with open top surfaces, the material in the storage box can be poured out through the gap between the crossbeam 23 and the first top frame 21.
[0033] Furthermore, such as Figure 4 As shown, the first top frame 21 is a rectangular frame, and the two lifting assemblies 1 are respectively installed on the outside of the first top frame 21. At this time, when lifting some storage boxes with top openings, such as when the spreader 4 lifts a container with a top opening, the top opening of the storage box can be lifted to be located inside the first top frame 21. Then, when the storage box is flipped to be tilted downwards or when the top opening of the storage box is flipped downwards, the material in the storage box can be easily poured out through the first top frame 21.
[0034] Furthermore, such as Figure 3 As shown, each support structure 11 is covered with a cover 18, which can protect the entire lifting assembly 1. In addition, the top of the cover 18 is higher than the first top frame 21, and the inner side of the top of the cover 18 extends horizontally into the first top frame 21 to form a limiting protrusion 181, which can limit the lifting height of the heavy object or the lifting device 4.
[0035] The specific arrangement of the inverted U-shaped hanger 3 is as follows: as shown in Figure 1 , Figure 3 and Figure 4 , the inverted U-shaped hanger 3 comprises a horizontally arranged second top frame 31, two vertically opposite distributed second side frames 32 are mounted at both ends of the second top frame 31, a support column 33 is mounted on the top surface of the second side frame 32, the top end of the support column 33 is detachably fixedly connected with the second top frame 31, specifically, a connecting plate 34 is mounted on the top end of the support column 33 and the second top frame 31, the connecting plates 34 located on the support column 33 and the second top frame 31 are opposite to each other, and the opposite connecting plates 34 are connected through a bolt connecting pair 35, so that the second top frame 31 and the second side frame 32 can be easily disassembled; in addition, after the second top frame 31 is removed, the height of the inverted U-shaped hanger 3 can be reduced, so as to facilitate the transportation of the turnover spreader.
