[0030] Among them, Figure 1 、 Figure 2 、 Figure 3 、Figure 4 and Figure 5 The reference direction coordinate system of the embodiments of the present application is given. The embodiments of the present application will be described below in conjunction with the directions shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 .

[0031] An embodiment of the present application provides a hoisting system, which includes a support frame 100, a conveying mechanism 200 and a driving assembly 250. A support beam 110 is arranged on the support frame 100 in the horizontal direction. The conveying mechanism 200 includes a hoisting assembly 210, a mounting seat 220, a base 230 and a rolling member 240 capable of moving along the support beam 110. The mounting seat 220 can move relative to the base 230. The mounting seat 220 is located above the support beam 110, and the base 230 is located below the support beam 110. A first brake pad 221 is provided on the mounting seat 220. The driving assembly 250 is arranged on the base 230. The driving assembly 250 is connected to the mounting seat 220 and can drive the first brake pad 221 to contact or separate from the rolling member 240.

[0032] This hoisting system can be used in the steel structure enclosure project. When an object needs to be transported, the object is fixed on the hoisting assembly 210. In the state where the first brake pad 221 is separated from the rolling member 240, the conveying mechanism 200 is pulled. At this time, the conveying mechanism 200 drives the object to achieve horizontal movement along the support beam 110. When it is necessary to stop transporting items, the first brake pad 221 is brought into contact with the rolling member 240. At this time, the first brake pad 221 can prevent the movement of the rolling member 240, thereby generating a braking effect of the first brake pad holding the rolling member 240. This hoisting system provides convenience and improves efficiency for the installation of the enclosure project. Compared with the existing hoisting methods, the present application has the advantages of strong applicability, convenient movement of items, easy installation and disassembly, safety and high efficiency, etc. The hoisting method using this hoisting system has a simple and easy-to-operate construction method process, can effectively improve the efficiency and safety of the steel structure enclosure project, standardize the current situation of hoisting construction in the existing enclosure project, and reduce on-site safety hazards.

[0033] In some embodiments, the driving assembly 250 includes a reel 251 and a connecting rope 252. The reel 251 is rotatably connected to the base 230. One end of the connecting rope 252 is wound around the reel 251, and the other end of the connecting rope 252 is connected to the mounting seat 220. By winding the reel 251, the connecting rope 252 can be tightened, so as to pull down the mounting seat 220 through the connecting rope 252. When the mounting seat 220 moves downward, the first brake pad 221 contacts the rolling member 240, achieving the effect of the first brake pad clamping the sliding wheel. The connecting rope 252 is a nylon rope, and the two ends (the top end) of the nylon rope are respectively connected to the left side and the right side of the mounting seat 220, and the middle position (the bottom end) of the nylon rope is wound around the reel 251. It can be understood that it is necessary to ensure that the lengths on both sides are the same to avoid unequal forces and inability to lock when tightening the nylon rope. In other embodiments, the driving assembly 250 can also adopt electric drive or hydraulic drive, etc.

[0034] In some embodiments, a sprocket 253 is fixedly connected to the outer periphery of the reel 251. The sprocket 253 is coaxially arranged with the reel 251. The driving assembly 250 includes a chain 254 that cooperates with the sprocket 253. An operator can stand on the ground and pull the chain 254 to adjust the moving state of the conveying mechanism 200, without the need for repeated climbing operations, occupying less on-site resources, having a high frequency of use in hoisting, covering a wide range of application scenarios, being different from the hoisting operations of truck cranes and tower cranes, with significant economic benefits. The transmission efficiency of using the chain 254 to drive the sprocket 253 to rotate is relatively high, it can work in harsh environments such as high temperature and dust, and can achieve long-distance transmission, with a relatively simple structure, low maintenance cost, and accurate transmission ratio. In other embodiments, an electric motor can also be used to drive the sprocket 253 to rotate.

[0035] When the hoisting assembly 210 is moved to the required position, one side of the chain 254 is pulled (pulled along a fixed direction), and the sprocket 253 and the reel 251 rotate counterclockwise accordingly, tightening the connecting ropes 252 on both sides and driving the connecting rope 252 wheels to rotate in the same way. At the same time, the reel 251 starts to wind the connecting rope 252, gradually tightening the elastic connecting rope 252, causing the upper mounting seat 220 to move towards the support beam 110. When the tension of the connecting rope 252 is greater than the upward force of the elastic member 262, the mounting seat 220 drives the first brake pad 221 to descend as a whole and tightly contact the rolling member 240. At this time, the rolling member 240 is locked and cannot rotate. It can be understood that a second brake pad is provided on the top of the base 230, and the second brake pad is located below the support beam 110. When the tension of the connecting rope 252 is greater than the upward force of the elastic member 262, the second brake pad on the top of the base 230 also fits and frictions with the lower plane of the support beam 110, providing upper and lower constraints. At this time, the hoisting system is fixed and enters the hoisting state; when it is necessary to translate the object connected to the hoisting assembly 210, the other side of the chain 254 is pulled, and the sprocket 253 and the reel 251 rotate clockwise accordingly, and the connecting ropes 252 on both sides are relaxed. At this time, the constraint is released, and the elastic member 262 works to lift the mounting seat 220 with the first brake pad 221, and the base 230 descends and does not contact the lower plane of the support beam 110. At this time, the hoisting system enters the sliding state, and pulling both ends of the connecting rope 252 can perform left and right translation.

[0036] In some embodiments, the conveying mechanism 200 includes a vehicle frame 260, and the vehicle frame 260 is located on the outer periphery of the support beam 110 to ensure stable force and a firm frame body. The base 230 is fixedly connected to the bottom of the vehicle frame 260, and the mounting seat 220 is slidably connected to the top of the vehicle frame 260.

[0037] In some embodiments, a guide rod 261 is provided on the vehicle frame 260 in the height direction, and a guide cylinder 222 cooperating with the guide rod 261 is provided on the mounting seat 220.

[0038] In some embodiments, the hoisting assembly 210 includes an electric hoist installed on the outer side wall of the mounting seat 220. It can be understood that the hoisting assembly 210 may also include a fixed pulley hook, a movable pulley hook, etc. After the power is turned on, it can be debugged and used.

[0039] In some embodiments, the first brake pad 221 is provided at the bottom of the mounting seat 220, the rolling member 240 is installed on the vehicle frame 260, the rolling member 240 is located on the top surface of the support beam 110, and the first brake pad 221 is located between the mounting seat 220 and the rolling member 240.

[0040] In some embodiments, an elastic member 262 is provided between the bottom of the mounting base 220 and the vehicle frame 260. The elastic member 262 can support the separation of the first brake pad 221 from the rolling member 240. The elastic member 262 is a jacking spring. When the connecting rope 252 is not tightened, the jacking spring can jack up the mounting base 220 so that the first brake pad 221 does not contact the rolling member 240 (wheel), and the rolling member 240 (wheel) can rotate.

[0041] Specifically, the vehicle frame 260 is a firm support structure formed by assembling a pair of L-shaped brackets and a pair of lower T-shaped brackets to be fixed on the support beam 110. The L-shaped brackets and the T-shaped brackets are made of two square steel bars (hollow square steel bars).

[0042] In some embodiments, there are two support frames 100. A support beam 110 is provided between the two support frames 100. A plurality of support portions 120 are provided on the support frame 100 along the height direction.

[0043] The hoisting method using the hoisting system in the above embodiments includes the following steps:

[0044] The hoisting assembly 210 hoists the object to be hoisted.

[0045] Bring the first brake pad 221 into contact with the rolling member 240, and the conveying mechanism 200 stops operating.

[0046] Separate the first brake pad 221 from the rolling member 240, pull the driving assembly 250, and the conveying mechanism 200 moves along the support beam 110.

[0047] When it is necessary to transfer an object between bays, remove the conveying mechanism 200 from the support beam 110 as a whole, transfer it to another bay, and then resume the conveying mechanism 200.

[0048] In the existing hoisting and installation technology, a self-made climbing scaffold is often used in combination with a fixed pulley for hoisting and installation. However, due to the relatively high height of the enclosure structure and for the convenience of moving the position, the climbing scaffold is often welded into a square column-shaped frame body of more than ten meters with galvanized round steel. The height-width ratio is much greater than the 3:1 required for the operation platform. Then, only simple binding is carried out with steel wires and the main structure for climbing operations. At the same time, for the convenience of hoisting, the pulley hook is often randomly hung on the building peripheral components or the climbing scaffold, so as to realize high-altitude operations and hoisting operations, bringing great potential safety hazards to the installation personnel and the construction site. In addition, whether the fixed pulley hook is hung directly on the climbing scaffold or the building peripheral components, it is necessary to continuously adjust the position of the hook as the hoisting position progresses, resulting in cumbersome construction and low efficiency. If a truck crane or tower crane is used for hoisting, due to the large number and light weight of the enclosure components, it will cause working hours under low load and low economic benefits.

[0049] However, the hoisting method using the hoisting system of the present application can solve the construction technical problems in the prior art, such as the random fixation of the hoisting hook, the non-standard high-altitude operation, the inconvenient installation, disassembly and movement, and the low construction efficiency. It can realize the horizontal displacement of the object on the support beam 110, reduce the influence caused by the frequent change of the hoisting point, improve the construction efficiency, and the hoisting method using the hoisting system realizes the adjustment of the sliding state of the bracket on the ground, reduces the situation of non-standard high-altitude operation on site, reduces the on-site construction risk, helps to reduce the situation of non-standard high-altitude operation and random hanging of pulleys for lifting on site, reduces potential safety hazards, is simple and easy to operate, reduces the high-altitude operation adjustment, and ensures the construction efficiency while saving labor.
