[0002] In the construction of the roof layer of a building, especially in a building with a unique shaped structure, the hoisting operation of curtain wall units has always been a technical problem. The roof layer often bears the aesthetic design and functional requirements of the building.

For the traditional tower crane hoisting method, when facing such complex structures, it is often difficult to effectively complete the hoisting operation of the lower curtain wall unit body due to space limitations, line of sight obstruction or insufficient operating angles, and also due to the limited operating height of truck cranes and the problems that common hoisting ring rails cannot be installed or used.

[0051] As Figures 1 to 4 shown, this application provides an overhead rail hoisting device, which includes a plurality of hanging brackets 1, a tie beam 2, a hoisting rail 3, and a hoisting device 4. Among them, the hanging brackets 1 are arranged at intervals in sequence along the outer edge direction of the lower structure to construct a plurality of support points of this hoisting device on the outer edge of the lower structure. At least one end of the hanging bracket 1 extends to the outside of the outer edge of the lower structure, so that the hoisting device 4 running thereon can avoid the special-shaped structures on the outer edge of the roof layer for hoisting operations. The tie beam 2, as a transverse connecting member, is connected to two adjacent hanging brackets 1. It can not only enhance the overall stability of this hoisting device but also provide the necessary lateral support force. The connection between the tie beam 2 and the hanging bracket 1 can be made by a bolt group. The hoisting rail 3 is horizontally connected to two adjacent hanging brackets 1 and is located at the outer end where the hanging bracket 1 extends to the outside of the outer edge of the lower structure, so as to facilitate the hoisting device 4 to run in an unobstructed space. The hoisting device 4, as the core functional component of the hoisting operation, can move flexibly on the hoisting rail 3. The hoisting device 4 has rollers to ensure that the hoisting device 4 rolls smoothly on the hoisting rail 3, reducing wear and resistance. The hoisting device 4 includes components such as a winch, a hoisting rope, and a hook. By controlling the winch to drive the retraction and release of the hoisting rope, the hook is driven to lift and lower, thereby realizing the hoisting or operation of various materials. Since the hoisting device 4 uses existing equipment, it will not be elaborated in detail here. The hanging bracket 1 can be constructed with I-beams, square steels, U-shaped steels, etc., and the tie beam 2 and the hoisting rail 3 can both be constructed with I-beams. As Figure 5 and Figure 6 shown, this overhead rail hoisting device can be used for hoisting objects or people. Among them, the hoisting device 4 can operate alone or be jointly hoisted by a plurality of hoisting devices 4. The lifting points on this overhead rail hoisting device can, according to the operation requirements, set a plurality of hoisting devices 4 in the same span of each hanging bracket 1 or hoist the same equipment, device, or component with different hoisting devices 4 on multiple spans simultaneously. The overhead rail hoisting device of this application is also applicable to operations such as the exterior maintenance, cleaning, etc. of high-rise buildings. This overhead rail hoisting device has the advantages of simple structure, clear force transmission, convenient installation and disassembly, and low manufacturing cost.

[0052] AsFigure 3 and Figure 4 As shown in Figure 3 and Figure 4 , in an embodiment of the present application, the hanger 1 includes a column 11, an inner diagonal brace 12, an outer diagonal brace 13, a first cross beam 14, and a second cross beam 15. Among them, the column 11 can be specifically made of square pipe. The bottom end of the column 11 is fixedly connected to the lower structure with sufficient bearing capacity to ensure the stable connection of the entire hanger 1 to the lower structure. Bolt holes are also provided on the column 11 for bolt connection with the first cross beam 14 and the steel plate 112 with bolt holes. The inner diagonal brace 12 is arranged at an angle with the column 11, and the inner diagonal brace 12 inclines towards the inner side of the outer edge of the lower structure; the outer diagonal brace 13 is arranged at an angle with the column 11, and the outer diagonal brace 13 inclines towards the outer side of the outer edge of the lower structure. One end of the first cross beam 14 is connected to the column 11. Specifically, a connecting plate is provided at one end of the first cross beam 14, and bolt holes are provided on the connecting plate. The first cross beam 14 and the column 11 are connected by means of bolt connection. To achieve the adjustable installation elevation position of the first cross beam 14, bolt holes corresponding to the installation height can be respectively provided at different elevation positions on the column 11. The other end of the first cross beam 14 is cantilevered and extends to the outer side of the outer edge of the lower structure, and the outer diagonal brace 13 is supported between the two ends of the first cross beam 14; the column 11, the first cross beam 14, and the outer diagonal brace 13 form a triangular structure. The first cross beam 14 is connected to the tie beam 2 on one side of the hanger 1. The second cross beam 15 is located above the first cross beam 14. One end of the second cross beam 15 is connected to the inner diagonal brace 12, and the other end of the second cross beam 15 is cantilevered and extends to the outer side of the outer edge of the lower structure, and the column 11 is supported between the two ends of the second cross beam 15; the column 11, the second cross beam 15, and the inner diagonal brace 12 form another triangular structure. The second cross beam 15 is connected to the tie beam 2 on the other side of the hanger 1. The suspension rail 3 is connected to the first cross beam 14 and / or the second cross beam 15. Affected by the slope of the lower structure, the first cross beam 14 in the hanger 1 and the second cross beam 15 in the hanger 1 at the lower level are in the same plane, and the second cross beam 15 in the hanger 1 and the first cross beam 14 in the hanger 1 at the higher level are in the same plane. When there is no slope in the lower structure, that is, when the elevation of the hanger 1 is in the same plane, the first cross beams 14 on two adjacent hangers 1 are at the same elevation, and the second cross beams 15 are also at the same elevation.

[0053] In addition, a plurality of connection position bolt holes can be provided on the first cross beam 14 at a certain interval to achieve adjustable connection positions, that is, to facilitate the connection between the first cross beam 14 and the outer diagonal brace 13 when adjusting the elevation of the first cross beam 14, and to adjust the connection position of the outer diagonal brace 13 connected to the first cross beam 14 as needed. At the connection position between the suspension rail 3 and the first cross beam 14 or the second cross beam 15, the levelness of the suspension rail 3 can be adjusted by adding steel plates.

[0054] In an embodiment of the present application, the suspension rail 3 may specifically adopt an I-beam. When both the lower structure and the suspension rail 3 are in a horizontal state, the upper flange at one end of the suspension rail 3 is connected to the lower flange of the first crossbeam 14 of a hanger 1, and the upper flange at the other end of the suspension rail 3 is connected to the lower flange of the first crossbeam 14 of an adjacent hanger 1; alternatively, the upper flange at one end of the suspension rail 3 is connected to the lower flange of the second crossbeam 15 of a hanger 1, and the upper flange at the other end of the suspension rail 3 is connected to the lower flange of the second crossbeam 15 of an adjacent hanger 1.

[0055] When the lower structure is in an inclined state and the suspension rail 3 is in a horizontal state, the upper flange at one end of the suspension rail 3 is connected to the lower flange of the first crossbeam 14 of a hanger 1, and the upper flange at the other end of the suspension rail 3 is connected to the lower flange of the second crossbeam 15 of an adjacent hanger 1.

[0056] In other embodiments of the present application, the suspension rail 3 may also be a C-shaped steel, an H-shaped steel, an L-shaped steel, etc.

[0057] As Figure 3 shown, in an embodiment of the present application, the hanger 1 further includes a support column 16. One end of the support column 16 is connected to the first crossbeam 14, and the other end of the support column 16 is connected to the second crossbeam 15. The support column 16 is used to reduce the overhanging length of the second crossbeam 15 and enhance the bending resistance of the second crossbeam 15. In addition, the support column 16 should also be arranged at intervals with the column 11. Both ends of the support column 16 have end plates with bolt holes opened. Correspondingly, bolt holes are also opened at different positions on the first crossbeam 14 and the second crossbeam 15. By docking the support column 16 with different bolt holes on the first crossbeam 14 and the second crossbeam 15, the connection positions of the support column 16 with the first crossbeam 14 and the second crossbeam 15 can be adjusted.

[0058] In an embodiment of the present application, the length that the second crossbeam 15 extends out of the outer edge of the lower structure is greater than the length that the first crossbeam 14 extends out of the outer edge of the lower structure. The suspension rail 3 installed on the second crossbeam 15 can extend further outwards, thereby increasing or adjusting the lifting range of the lifting device 4.

[0059] In other embodiments of the present application, the length that the second crossbeam 15 extends out of the outer edge of the lower structure may also be less than or equal to the length that the first crossbeam 14 extends out of the outer edge of the lower structure. The specific setting method needs to be determined according to the actual working conditions. In addition, the lengths that the first crossbeam 14 and the second crossbeam 15 of different hangers 1 extend out of the outer edge of the lower structure can all be different.

[0060] In one embodiment of the present application, the first crossbeam 14 and / or the second crossbeam 15 are telescopic crossbeams to adjust the length of the cantilevered end of the first crossbeam 14 and / or the second crossbeam 15 extending out of the outer edge of the lower structure. Specifically, the specific method of realizing the telescopic nature of the first crossbeam 14 and / or the second crossbeam 15 can be to use two steels connected inside and outside, and insert bolts or pins to fix the relative positions of the two steels to achieve the telescopic nature of the crossbeam. Since the telescopic crossbeam is an existing mature technology, other implementation methods will not be described in detail.

[0061] In one embodiment of the present application, in order to facilitate the installation of the hanger 1 under different elevation conditions, the column 11, the inner diagonal brace 12, the outer diagonal brace 13 and the supporting column 16 can be set as telescopic rods to adjust their lengths, thereby changing the specifications of the hanger 1. Specifically, the telescopic adjustment of the column 11 can change the overall height of the hanger 1; the telescopic adjustment of the inner diagonal brace 12 and the outer diagonal brace 13 can adapt to the change in length or height of the first beam 14 and the second beam 15, or the change in the connection position. The telescopic adjustment of the supporting column 16 is used to adapt to the change in the installation elevation of the first beam 14. The specific method of realizing the telescopic extension of the above-mentioned components can be two square steels connected inside and outside, and the relative positions of the inner and outer steels are fixed by inserting bolts or pins to realize the telescopic extension of the beam. Since the telescopic rod is an existing mature technology, other implementation methods will not be described in detail.

[0062] like Figure 3 and Figure 4 As shown, in one embodiment of the present application, the track hoisting device also includes a base pad 5, and the base pad 5 includes a wedge-shaped bottom surface 51 and a mounting surface 52. Among them, the wedge-shaped bottom surface 51 cooperates with the lower structure to make the mounting surface 52 in a horizontal position, and then the hanger 1 is installed on the mounting surface 52, so that the hanger 1 can be installed on a horizontal surface, avoiding safety hazards such as tilting and shaking of the hoisting device caused by the tilt of the mounting surface. The base pad 5 is fixed by bolts pre-embedded in the lower structure. In other embodiments of the present application, when the elevations of the lower structure of the hanger 1 are all in the same plane, the setting of the base pad 5 can also be cancelled. The hanger 1 is directly installed on the lower structure by pre-embedded bolts. When the lower structure is a steel structure, bolt holes can be opened as needed when the steel structure is manufactured, thereby realizing the bolt connection between the hanger 1 and the steel structure without pre-embedded bolts.

[0063] like Figure 7 and Figure 8 As shown, in one embodiment of the present application, the bottom ends of the inner diagonal brace 12 and / or the outer diagonal brace 13 can also be hinged to the column 11 or the bottom plate of the column 11 so that the angle between the inner diagonal brace 12 and / or the outer diagonal brace 13 and the column 11 can be adjusted.

[0064] When the inner diagonal brace 12 and the outer diagonal brace 13 are connected to the column 11 or the cross beam, the end of the diagonal brace rod is provided with an ear plate 132. The ear plate 132 is pin-connected with a steel plate 112 which is provided with bolt holes and an ear plate 111. The steel plate 112 with bolt holes and an ear plate is connected to the column 11 through bolts.

[0065] When the inner diagonal brace 12 and the outer diagonal brace 13 are connected to the bottom plate of the column 11, an ear plate 111 with a pin hole is welded on the bottom plate of the column, and then it is pin-connected with the ear plate 132 at the end of the diagonal brace rod.

[0066] In order to connect the ear plate 132 to the end of the diagonal brace whose cross-sectional shape is not convenient for directly connecting the ear plate 132 in some cases, an end plate 131 can also be welded on the end of the diagonal brace, and then the ear plate 132 is welded on the end plate 131.

[0067] In an embodiment of the present application, the spacing distance between the hanging brackets 1 is generally 2.5 m to avoid excessive structural strength redundancy of the hanging brackets 1. The actual spacing distance between the hanging brackets 1 can be determined according to the usage requirements. In the case of heavier lifting weights and wider spacing distances, the structural strength can be improved by increasing the model specifications of the hanging brackets 1 and the tie beams 2 to meet the lifting requirements. Since the hanging brackets 1 can be flexibly disassembled and assembled, the appropriate number of hanging brackets 1 can be configured according to the usage requirements. In the case of changes in the elevation of the lower structure, the elevation position of the cross beam 15 can be adjusted according to the construction requirements, so as to ensure that the lifting rail 3 is on the horizontal plane and ensure that it is applicable to the working conditions of various different lower structure elevations.

[0068] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
