[0002] According to the needs of building curtain wall decoration, exterior wall panel construction, enclosure structure construction, etc., hanging baskets have been widely used in modern engineering as commonly used operating machinery. However, for portal frame structures, since the steel structure roof is a corrugated steel plate, it cannot bear the weight of the counterweight, and the bracket or counterweight of the standard hanging basket cannot be installed normally.

[0052] Combination Figures 1 to 10 , further illustrating the construction method of the above-mentioned hanging basket suspension structure installation system on the portal structure, the specific steps are as follows:

[0053] Step 1: Design and assemble the hanging basket according to the height and length of the portal structure; determine the position and number of the main suspension mechanism 4 and the side suspension mechanism 8 based on the position and number of the vertical columns 2 and side columns 3 on the portal structure; select the wire rope 7 and the hoist according to the weight that the hanging basket needs to bear; and install the safety lock, support and electrical control box of the hanging basket.

[0054] When assembling the hanging basket, first assemble the hanging basket base frame and the front and rear railings with bolts, assemble the basket body length according to the actual needs of the site, and then assemble the hoist mounting frames at both ends.

[0055] Step 2. According to the pre-designed numbers, respectively hoist the main upright frame 41, the main connecting member 42 and the main cross frame 43 on the main suspension mechanism 4 onto the portal structure and assemble them; respectively hoist the side front upright frame 81, the side rear upright frame 83 and the side cross frame 82 in the side suspension mechanism 8 onto the portal structure and assemble them.

[0056] During the construction of the main suspension mechanism 4 and the side suspension mechanism 8, the construction workers first wear safety protection equipment, use a 0.5T hoist to transport them to the top of the portal structure according to the number, use M16 clamps to fix the components to be connected to the connecting beam 1, the cross beam or the side column 3, and then install other components; when placing the main suspension mechanism 4 and the side suspension mechanism 8, their front ends must meet the construction position requirements, and at the same time, ensure that the distance at the front end is consistent with the width of the basket below to avoid the hanging basket from forming an eight-shaped shape after installation, which affects the safe use of the hanging basket.

[0057] Step three, check and correct the position and connection tightness of the main suspension mechanism 4 and the side suspension mechanism 8, and make timely adjustments if they are unqualified; after they are qualified, the lifting wire rope 71 will be respectively passed through the suspension mechanism and the side suspension mechanism 8, and finally connected to the hanging basket; in addition, a safety wire rope 72 is configured on the corresponding main suspension mechanism 4 and the side suspension mechanism 8.

[0058] During the construction of the wire rope 7, tighten the connecting bolts at each part, tighten the reinforcing wire rope 7 with the rigging spiral buckle, add a certain pre-tightening force to the wire rope 7, and take anti-slip measures. The end of the wire rope 7 is tightened with a rope clamp. There are four rope clamps with a spacing of 80mm. The rope seat of the wire rope 7 is clamped on the working section of the wire rope 7. The U-bolt is buckled on the tail section of the wire rope 7, and a safety bend is left between the 3rd and 4th rope clamps. When the main suspension mechanism 4 and the side suspension mechanism 8 extend 1.5 meters forward, the front end of the lifting wire rope 71 should be bent upward by 30mm. Assemble the lifting wire rope 71 and the safety wire rope 72 on the main suspension mechanism 4 and the side suspension mechanism 8 and install the limit block.

[0059] After the main suspension mechanism 4 and the side suspension mechanism 8 are all installed and checked for problems, the lifting wire rope 71 is lowered from the top to the ground. The lifting wire rope 71 should be lowered little by little and cannot be thrown down directly. When the lifting wire rope 71 is lowered, a soft isolation such as wood should be placed between the lifting wire rope 71 and the structure to prevent the lifting wire rope 71 from being damaged by friction with the structure during the lowering process, thereby affecting safety.

[0060] After lowering the lifting wire rope 71, turn on the power supply of the hanging basket, pass the lifting wire rope 71 through the lifting frame guide rope wheel, and then insert it into the rope inlet of the hoist, start the hoist, and the lifting wire rope 71 will automatically wind up and extend from the other exit. For the safety wire rope 72, just insert it directly when the safety lock is in the non-clamped state. After the whole machine is installed, check whether each connection is reliable.

[0061] Step 4: Test run the hanging basket, check the stability of the hanging basket's ascent, monitor whether the verticality and position of the main suspension mechanism 4 and the side suspension mechanism 8 change after operation and stabilization, and carry out the hanging basket construction after passing the inspection.

[0062] Power on the hanging basket for normal test run. The operator controls the handle to start and run the hanging basket up and down 3-5 times, 1-1.5 meters above the ground. If there are no other problems, put the hanging basket on the ground. During operation, hang the weight on the lower end of the lifting wire rope 71 and the safety wire rope 72, slightly away from the ground, so that the lifting wire rope 71 and the safety wire rope 72 are kept in a suspended and tensioned state during the operation of the hanging basket to ensure the normal operation of the safety lock.

[0063] Step 5: After the construction of one portal structure is completed and the hanging basket is lowered, the connection between the main suspension mechanism 4 and the side suspension mechanism 8 and the portal structure is released, and then the construction of the next portal structure can be carried out.

[0064] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that a technician familiar with the technical field can think of within the technical scope disclosed in the present invention should be covered within the protection scope of the present invention.
