DETAILED DESCRIPTION

[0028] The present application is further described below in conjunction with specific embodiments and drawings.

[0029] refer to Figure 1 to Figure 7 As shown, a high-altitude work hoisting device includes a hoist cage 1, a general supporting platform 2, a temporary consolidation mechanism 3, a dragging mechanism 4 and a floor slab 5.

[0030] The cage 1 is hooked by a crane, and the crane is used to realize the lifting and horizontal displacement of the cage 1. The cage 1 is used to carry the general bearing platform 2, and the general bearing platform 2 can slide horizontally in the cage 1. The sliding span is between the inside and outside of the cage. The general bearing platform 2 is used to directly carry the suspended equipment. The suspended equipment is placed on the general bearing platform 2 to ensure the stability of the suspended equipment itself. The suspended equipment cannot slide or fall on the general bearing platform 2. The temporary consolidation mechanism 3 temporarily fixes the cage 1 when the cage 1 is hoisted to the suspended edge of the floor slab 5 to ensure the stability of the suspended equipment during the transition.

[0031] The cage 1 includes a hoisting beam 101 , a hoisting rope 102 , a cage frame 103 , an opening and closing baffle 104 , a slideway 105 , a positioning hole 106 and a positioning plate 107 .

[0032] The hoisting beam 101 is connected to the crane, and the hoisting beam 101 is respectively connected to the front, middle and rear parts of both sides of the cage frame 103 through the hoisting rope 102 (wire rope). The crane realizes the hoisting of the cage frame 103 through the hoisting beam 101 and the hoisting rope 102, and the six-point arrangement of the hoisting rope 102 has good stability.

[0033] The cage 103 is a rectangular parallelepiped frame welded from steel sections, and has an upper opening for the equipment to enter and exit. An opening and closing baffle 104 is provided on one side of the cage 103, and the opening and closing baffle 104 can be hinged to flip upward, flip left or flip right, and is opened when the hoisted equipment needs to be transported out from the side, and is closed under normal circumstances.

[0034] A slideway 105 is fixedly provided at the bottom of the cage 103, and two slideways 105 are arranged on both sides of the cage 1 to ensure the stability of the sliding of the general support platform 2. One end of the slideway 105 is located in the cage 103, and the other end of the slideway 105 extends out of the cage 103 from the side of the opening and closing baffle 104, so that the general support platform 2 can slide between the inside and outside of the cage.

[0035] Positioning holes 106 and positioning plates 107 are fixed on both sides of the slideway 105 . The positioning holes 106 are used to fix the overall supporting platform 2 relative to the slideway 105 , and the positioning plates 107 are used to fix the slideway 105 relative to the floor slab 5 .

[0036] The overall supporting platform 2 includes a platform plate 201 , a supporting slide rail 202 , a pulley 203 , a mounting hole 204 and a positioning member 205 .

[0037] A support rail 202 is fixedly provided at the bottom of the platform plate 201, and two support rails 202 are arranged on both sides of the platform plate 201, and the two support rails 202 correspond to two slideways 105. A pulley 203 is provided at the bottom of the support rail 202, and the pulley 203 rolls in the slideway 105, so that the support rail 202 and the platform plate 201 slide horizontally between the cage inner position and the cage outer position on the slideway 105, thereby realizing the horizontal sliding of the platform plate 201 relative to the cage 1.

[0038] The slide 105 is fixed with positioning holes 106 on both sides, and the supporting slide rail 202 is fixed with mounting holes 204 on both sides. The positioning member 205 is inserted into the mounting hole 204 and the positioning hole 106 in the cage. The positioning member 205 can be specifically in the form of a pin. The pin is inserted into the two holes together to achieve locking between the slide 105 and the supporting slide rail 202, thereby achieving locking of the total supporting platform 2 in the cage 1.

[0039] A temporary consolidation mechanism 3 for acting on the cage 103 and the slide 105 is provided on the floor 5. The temporary consolidation mechanism 3 includes a slide fixer 301 and a cage fixer 305. When the cage 1 carries the hoisted equipment and lifts it to the suspended edge of the floor 5, the slide fixer 301 is used to fix the slide 105 to the floor 5, and the cage fixer 305 is used to fix the cage 103 to the floor 5.

[0040] The slideway fixture 301 includes a mounting seat 302, a fastening handle 303 and a fastening plate 304. The mounting seat 302 is hinged on the floor 5 and can be flipped relative to the floor 5. When the positioning plate 107 enters between the relative mounting seats 302, the mounting seat 302 is flipped open to avoid interference during entry. When the positioning plate 107 needs to be temporarily fixed, the mounting seat 302 is flipped so that the fastening plate 304 is located above the positioning plate 107.

[0041] The mounting seat 302 is provided on the floor 5, and the mounting seat 302 is arranged on both sides of the slideway 105. The mounting seat 302 is provided with a fastening handle 303 for up and down adjustment. The fastening handle 303 can be adjusted up and down by a threaded connection. The bottom end of the fastening handle 303 is fixedly connected with a fastening plate 304, and the fastening plate 304 cooperates with the positioning plate 107 on the slideway 105. By rotating the fastening handle 303, the fastening plate 304 moves up and down, and pressing the positioning plate 107 downward can achieve its temporary consolidation, thereby ensuring the fixation of both sides of the slideway 105.

[0042] The cage fixer 305 includes a fixing point 306 and a fixing rope 307 (wire rope). The fixing point 306 is arranged on the floor 5. The fixing point 306 can adopt a pre-embedded cast lug. The fixing point 306 is connected to the cage frame 103 through the fixing rope 307. The fixing rope 307 is the fixing rope of a hand winch. The hand winch is connected to the fixing point 306. The fixing rope 307 is tensioned by the hand winch to achieve tension and fixation of both sides of the cage.

[0043] The dragging mechanism 4 is used to drag the general bearing platform 2 from the cage 1 to the top of the floor 5. The dragging mechanism 4 includes a dragging power source 401 and a towing rope 402. The towing power source 401 adopts a traction machine, a traction machine and other equipment driven by a motor. The dragging power source 401 is fixed on the floor 5. The towing mechanism 4 is connected to the platform plate 201 through the towing rope 402. Then, the towing power source 401 drags the general bearing platform 2 and the suspended equipment thereon to the floor 5 by retracting the towing rope 402.
