[0028] Embodiment 1:

[0029] Refer to Figure 1-2 As shown, an orbital lifting system includes at least two flat top beams 100 installed to span the working space 10. Each of the flat top beams 100 is parallel to each other. A first track 110 is installed on the flat top beam 100. At least one lifting trolley 200 is installed on the first tracks 110 of two adjacent flat top beams 100. A feeding platform 12 is provided on one side or both sides of the working space 10, and the feeding platform 12 is located below the flat top beam 100. By providing the feeding platform 12 on one side or both sides of the working space 10, the equipment or working materials on the feeding platform 12 can be hoisted to the construction working area by the lifting trolley 200, and the concrete can also be directly hoisted to the construction working area through the hopper, without installing multiple distributing booms, and the operation is simpler.

[0030] Every two flat top beams 100 form a group, and the lifting trolley 200 is installed on a group of flat top beams 100. Refer to Figure 2 , four flat top beams 100 are shown in the figure, which is three groups.

[0031] The lifting trolley 200 adopts a structure similar to that of the lifting trolley on a bridge crane and is used to hoist equipment materials and hoppers through a lifting appliance.

[0032] The working space 10 includes V-shaped valleys such as canyons, valleys, and river valleys.

[0033] Furthermore, a main platform 20 is provided at the end of the flat top beam 100. The feeding platform 12 is connected to the main platform 20 through a road 13, so that construction vehicles, equipment, or materials can drive or be transported to the feeding platform 12 through the road. Specifically, the main platform 20 and the feeding platform 12 are located on the same side of the working space 10, or main platforms 20 and feeding platforms 12 are provided on both sides of the working space 10.

[0034] Further, a plurality of second tracks 21 are installed at the end of the flat-top beam 100 on the main platform 20, and the second tracks 21 are respectively aligned with the first tracks 110 on the flat-top beam 100, which facilitates the hoisting trolley 200 to enter the flat-top beam 100 through the second tracks 21 for hoisting operations.

[0035] See Figure 1 , the flat-top beam 100 includes a main beam 101 and an arch beam 102, and the arch beam 102 is connected to the lower side of the main beam 101 through a vertical strut 103. Through the combined installation of the main beam 101, the arch beam 102 and the vertical strut 103, the structural strength of the flat-top beam 100 is ensured.

[0036] Further, foundation platforms 11 are respectively arranged on both sides of the working space 10, and both ends of the main beam 101 are respectively installed on the upper side surfaces of the foundation platforms 11 on both sides, which is convenient for installation and fixation; both ends of the arch beam 102 are respectively installed on the side surfaces of the opposite sides of the foundation platforms 11 on both sides. When the arch beam 102 is compressed, since both ends are rigidly connected, the deformation of the arch beam 102 can be reduced, so that the flat-top beam 100 has a greater load-bearing capacity.

[0037] Specifically, support columns 104 are respectively installed at both ends of the main beam 101, a base plate 105 is installed at the bottom of the support column 104, and the base plate 105 is fixedly installed and connected to the foundation platform 11, which is convenient for the installation and fixation of the main beam 101.

[0038] In this embodiment, the hoisting trolley 200 includes a traveling vehicle body 201. Two roller track wheels are respectively installed at the positions corresponding to the first tracks 110 on two adjacent flat-top beams 100 at the bottom of the traveling vehicle body 201. The traveling vehicle body 201 travels on the first tracks 110 through the drive of the roller track wheels. A hoisting system is installed inside the traveling vehicle body 201. The steel wire rope 202 of the hoisting system extends downward from between two adjacent flat-top beams 100, and a hook 204 is installed at the lower end of the steel wire rope 202 through a movable pulley 203.

[0039] When the hoisting trolley 200 moves onto the second track 21 or changes tracks, the steel wire rope 202 and the hook 204 are retracted and placed on the traveling vehicle body 201 to prevent the steel wire rope 202 and the hook 204 from interfering with the main platform 20.

[0040] Embodiment 2:

[0041] This patent adopts the flat-top arch beam structure form, specifically, multiple groups of flat-top beams 100 are fixedly installed in parallel on the foundation platforms 11 set in advance on both sides of the working space 10. In principle, the flat-top beams 100 completely cover the pouring area of the working space 10 below.

[0042] The main beam 101 of the flat-top beam 100 is reliably installed on the foundation platform 11 through the foundation plate 105 and bolts. Of course, the method of embedding a buried plate on the foundation platform 11 can also be adopted, and then the foundation plate 105 is reliably connected to the buried plate by welding.

[0043] In order to strengthen the strength and load-bearing capacity of the main beam 101, an arch beam 102 and a vertical brace 103 are arranged under the main beam 101. The two ends of the arch beam 102 reliably abut against the outer vertical surface of the foundation platform 11. Of course, various methods such as the two ends of the arch beam directly abutting against the vertical surface of the foundation platform, the buried plate welding method, and the bolt connection can also be adopted. For the convenience of installation and improvement of the load-bearing capacity of the above steel structure, a steel structure with a higher strength grade can be used, such as 800MPa or 1000MPa grade, and the structural form of I-beam is preferably selected.

[0044] A first track 110 is arranged above the main beam 101, and multiple groups of second tracks 21 are also arranged on the main platforms 20 on both sides of the working space in alignment and at the same elevation as the first track 110. This facilitates the hoisting trolley 200 to enter the main beam 101 from the main platform 20 through the second track 21 for hoisting operations. One or more hoisting trolleys 200 can be configured on a group of flat-top beams 100 according to needs and load-bearing conditions. The hoisting trolley 200 consists of a traveling vehicle body 201 and traveling wheels to form a traveling mechanism. A lifting winch system is installed in the trolley. The steel wire rope 202 wound on the lifting winch system is connected to the hook 204 through a lower connecting movable pulley 203 for hoisting objects or pouring operations.

[0045] A feeding platform 12 is arranged below the main platform 20. The feeding platform 12 is used for vehicles or equipment to transport construction materials or concrete loaded in a lifting bucket to this platform and then the concrete is hoisted into the construction position by the hook of the trolley. The feeding platform 12 is connected to the main platform 20 through a road 13 arranged on the main platform 20, so that construction vehicles, equipment or materials can drive or be transported to the feeding platform 12 through the road.

[0046] Gravity sensors are arranged under the foundation plates 105 of the support columns 104, and stress gauges are also arranged on the main beam 101, arch beam 102, vertical brace 103 and other parts respectively. Through the real-time detection of the gravity sensors and stress gauges by the system, the matching situation between the actual load and the load-bearing capacity of this patent can be known, so as to make the best use of the load-bearing capacity of the equipment. When a situation close to the load-bearing capacity occurs, safety operations such as timely alarming or shutdown are carried out.

[0047] Avoidance sensors are provided on both sides of the traveling vehicle body 201 of the hoisting trolley 200, which facilitates multiple hoisting trolleys 200 to avoid collision when approaching on the same rail. When two trolleys are relatively close, the avoidance sensors will sense and alarm, and transmit relevant information to the total control system. After analysis and judgment by the total control system, actions such as driving the trolley to leave, avoid, and stop will be issued in a timely manner to ensure the safe operation of each trolley.

[0048] The control of the device of this patent can adopt wired or wireless power supply methods, or both methods can be adopted but used as backups for each other, which can improve the reliability of signal transmission. In principle, the power supply is carried out by laying the line along the main beam and then passing through the trolley on the cable reel, which can ensure reliable power supply.

[0049] Obviously, the above embodiments are only examples given for clear illustration, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
