[0022] The main steel frame platform 5 is constructed of channel steel, with internal net dimensions of 7m long, 3m wide, and 1.5m high. The bottom is constructed of 16# channel steel with 1m spacing. The three sides have 1.2m high protective railings, constructed of 16# channel steel with 1m spacing. The center protective railings are constructed of 6# channel steel with 50cm spacing. A 0.75mm thick patterned steel plate 4 is laid above the platform.

[0023] Among them, the fixed roller pulley 7: DN80 seamless steel pipe is welded with the bearing, and the spacing is 1m. The fixed bearing seat 8 is firmly connected to the steel frame platform body 5.

[0024] In this embodiment, a large equipment 1 is placed on the steel frame platform body 5 , the bottom of the large equipment 1 is in contact with a plurality of fixed roller pulleys 7 , and the upper part is limited by the contact steel pipe scaffolding limiter 2 .

[0025] The steel frame platform body 5 is fixedly connected to the external tower crane steel cable through four lifting lugs 6 .

[0026] In this embodiment, the steel pipe scaffolding limiter 2 includes two longitudinal steel pipes 21, both ends of the two longitudinal steel pipes 21 are fixed with fixed limit seats 211, and the two longitudinal steel pipes 21 are symmetrically fixed to the tops of the opposite sides of the fixed railing 3 through the fixed limit seats 211, and an adjustable transverse limit structure 22 is slidably connected between the two longitudinal steel pipes 21; the adjustable transverse limit structure 22 includes a movable cylinder 225 slidably connected to the longitudinal steel pipe 21, and the external thread of the movable cylinder 225 is connected to an adjusting bolt 226, and the adjusting bolt 226 is slidably connected to the longitudinal steel pipe 21. 226 penetrates into the interior of the movable cylinder 225 and contacts and limits the longitudinal steel pipe 21. A rotating shaft seat 224 is fixed on the top of the movable cylinder 225, and a transverse steel pipe 221 is rotatably connected through the movable cylinder 225. A U-shaped seat 222 is fixed to the bottom of the transverse steel pipe 221 away from the movable cylinder 225. The U-shaped seat 222 is engaged with the other longitudinal steel pipe 21, and the external thread of the U-shaped seat 222 is connected to the adjusting bolt 223. The adjusting bolt 223 threads penetrate the interior of the U-shaped seat 222 and contacts and limits the other longitudinal steel pipe 21.

[0027] Specifically, before placing the large equipment 1, the adjustable transverse limiting structure 22 is turned over and opened before use, that is, the transverse steel pipe 221 is grasped and lifted upward, and the transverse steel pipe 221 is turned over and opened through the rotating shaft seat 224, exposing the fixed fence channel, so that the large equipment 1 can enter the steel frame platform body 5 without obstruction, and then the adjustable transverse limiting structure 22 is moved to the front by slidingly connecting it with the longitudinal steel pipe 21 through the movable cylinder 225.

[0028] The large equipment 1 is placed on the bearing surface of the steel frame platform body 5 and contacts with multiple fixed roller pulleys 7. The steel frame platform body 5 is adjusted and limited by the steel pipe scaffolding limiter 2, and the horizontal steel pipe 221 is grasped and flipped downward so that it is U-shaped and embedded in the other horizontal steel pipe 221. Then the horizontal steel pipe 221 is pushed to move on the two longitudinal steel pipes 21 so that it contacts the large equipment 1. The adjusting bolt 1 223 and the adjusting bolt 226 are tightened against the two longitudinal steel pipes 21 to fix the horizontal steel pipe 221, thereby limiting the large equipment 1 and effectively preventing the large equipment 1 from shifting during the lifting process. The safety is high. When pulling out the large equipment 1 later, it is only necessary to loosen the adjusting bolt 226, grasp the horizontal steel pipe 221, flip it upward and lift it up to expose the channel to pull out the large equipment 1. The operation is simple and convenient.

[0029] Example 2. On the basis of Example 1, the gantry limit device 10 includes two bases 102 fixed inside the floor, a gantry 101 is fixed on the top of the two bases 102, and each base 102 is provided with a limit groove 1021 facing the outer end face of the floor, and a locking bolt 103 is threadedly connected to the top of the base 102, and the locking bolt 103 passes through the inside of the limit groove 1021. The two bases 102 are inserted into the limit through the limit groove 1021 and the locking bolt 103 and the two platform limiters 9.

[0030] Specifically, a gantry limit device 10 is used, and the upper channel steel bolts are fixed. When the steel frame platform body 5 enters the interior of the floor, the platform limiter 9 of the steel frame platform body 5 is inserted into the gantry limit device 10 and locked;

[0031] When the floor personnel use a hook to pull the protruding lip plate at the front end of the steel frame platform body 5 into the floor, and then command the tower crane to drop the hook until the platform falls on the floor, the platform limiter 9 extends 2.5 meters into the exposed surface (the bottom channel steel is limited to offset the traction force), and at the same time, the platform limiter 9 is inserted into the limit groove 1021 of the two bases 102 of the gantry limit device 10, the ground anchor point is connected and fixed with the front ear 6 of the platform, and the locking bolt 103 is tightened against the platform limiter 9 to ensure reliable fixation, check the levelness of the platform, and ensure that the tail of the platform is higher than the indoor floor.

[0032] The working steps are as follows:

[0033] 1. Set up 4 ground anchors on the floor, and use a gantry limiter 10 as a supporting device. Fix it with channel steel bolts on the top. When the steel frame platform body 5 enters the interior of the floor, insert the platform limiter 9 of the steel frame platform body 5 into the gantry limiter 10 and lock it;

[0034] 2. Ground and floor assistants are in place. Ground personnel assemble the slings of the steel frame platform body 5 and hook them. The forklift places the large equipment 1 on the bearing surface of the steel frame platform body 5 and contacts multiple fixed roller pulleys 7. The steel frame platform body 5 is adjusted and limited by the steel pipe scaffolding limiter 2. According to the size of the large equipment 1, multiple adjustable transverse limiting structures 22 are moved on the transverse steel pipe 221. After contacting the large equipment 1, they are locked and limited. To open, just loosen the adjusting bolt 226 on the adjustable transverse limiting structure 22 and lift the adjustable transverse limiting structure 22.

[0035] 3. The crane commander sends a signal to the crane driver to conduct a trial lift and leveling. The crane fine-tunes the direction of the main body of the steel frame platform. At the same time, the ground personnel use two guy ropes to control the direction of the platform.

[0036] 4. Use the tower crane hook to lift the steel frame platform 5 carrying the equipment to the corresponding floor, and then adjust the amplitude to align the steel frame platform 5 with the floor receiving port;

[0037] 5. The floor personnel use a hook to pull the extended lip plate at the front end of the steel frame platform body 5 into the floor, and then command the tower crane to drop the hook until the platform falls on the floor. The platform limiter 9 extends 2.5 meters into the exposed surface (the bottom channel steel limit is to offset the traction force). At the same time, the platform limiter 9 is inserted into the limit groove 1021 of the two bases 102 of the gantry limit device 10. The ground anchor point is connected and fixed with the front ear 6 of the platform. The locking bolt 103 is tightened against the platform limiter 9 to ensure reliable fixation. Check the levelness of the platform to ensure that the tail of the platform is higher than the indoor floor.

[0038] 6. The personnel wearing safety belts will go forward to remove the binding belt at the front of the platform, connect the wire rope traction hook with the pull rope at the bottom of the equipment, and operate the traction machine to pull the large equipment 1 into the floor. The large equipment 1 is assisted in rolling by multiple fixed roller pulleys 7, which has low friction and facilitates the displacement and pulling out of the large equipment 1.
