[0037] Embodiment

[0038] The present invention provides an embedded steel link corridor 5 hoisting device, and the steel link corridor 5 is installed between two columnar buildings, such as Figures 1-6As shown in the figure, it includes two tower crane structures 1 arranged in pairs. The tower crane structures 1 are fixed on the cement foundation ground through bolt structures to ensure the load-bearing capacity of the tower crane and prevent the tower crane from tipping over. It also includes two lifting frames 3 installed between the two tower crane structures 1. The lifting frames 3 are parallel to the two tower crane structures 1, and the lifting frames 3 are also fixed on the cement foundation ground through bolts. The set lifting frames 3 are of a frame structure. Lifting brackets 6 are installed on both of the two lifting frames 3. The lifting brackets 6 are of a triangular structure, which can improve their load-bearing capacity for the corridor when hoisting the steel connecting corridor 5. A hydraulic lifter 7 is installed on the lifting bracket 6. The hydraulic lifter 7 is a conventional technical means. A first lifting rope is installed inside the hydraulic lifter 7, and a connector detachably connected to the steel connecting corridor 5 is installed on the first lifting rope. A second lifting rope detachably connected to the steel connecting corridor 5 is installed at the hoisting end of the tower crane structure 1. The set first lifting rope is responsible for the main lifting, and the second lifting rope assists in adjusting the attitude. In this way, the first lifting rope at the hoisting end of the tower crane and the second lifting rope inside the hydraulic lifter 7 form a "main and auxiliary double lifting points" to disperse the weight of the steel connecting corridor 5, avoid single-point overload, and ensure the balance of the corridor during the hoisting process. Clamping mechanisms for clamping the steel connecting corridor 5 are installed on both of the lifting frames 3, and a crawling mechanism moving along the extending direction of the lifting frame 3 is arranged inside the clamping mechanism; when the steel connecting corridor 5 moves to the designed elevation of the corridor under the lifting of the above-mentioned structure, the channel formed inside the clamping mechanism can provide construction space for the installation of the inlaid members on the main section of the steel connecting corridor 5 at high altitude, preventing the construction position of the operators from being limited when installing the inlaid members at high altitude, resulting in deviations in the installation of the inlaid members and the steel connecting corridor 5 and affecting the forming quality of the steel connecting corridor 5. The clamping mechanism cooperates with the crawling mechanism to gradually move along the vertical direction to achieve segmented precise positioning, control the installation of the steel connecting corridor 5 in stages, and improve the installation quality. And the set clamping structure can guide the steel connecting corridor 5 to move along the extending direction of the lifting frame 3, avoid its shaking during the hoisting process due to wind or other factors, and improve the safety during hoisting. Through the coordinated operation of the two tower crane structures 1 and combined with the synchronous lifting function of the hydraulic lifter 7, the steel connecting corridor 5 is hoisted in segments to the target height. After the hoisting of the main section of the steel connecting corridor 5 is completed, the first lifting rope is unloaded from the main section of the steel connecting corridor 5, and the main section of the steel connecting corridor 5 is temporarily fixed at the target height by the second lifting rope and the clamping structure; then the remaining segmented steel connecting corridors 5 are hoisted to the assembling height again by the tower crane structure 1, and the segmented steel connecting corridors 5 enter the installation channel inside the clamping structure. Subsequently, the operators assist by the clamping structure to splice the segmented steel connecting corridors 5 and the inlaid members with the main section of the steel connecting corridor 5 at high altitude, improving the efficiency of the high-altitude splicing of the steel connecting corridor 5 by this structure.

[0039] In some technical solutions of the present invention, the holding frame mechanism includes a frame body 9 and a connecting frame 10 arranged in pairs, and the two frame bodies 9 are installed on the side walls of the connecting frame 10, and the connecting frame 10 is provided with a control mechanism for controlling the relative movement of the two connecting frames 10. A plurality of retaining frames 18 are installed on the opposite side walls of the frame body 9, and the retaining frames 18 are telescopic rod structures. The retaining frames 18 are detachably connected to the rods of the main steel corridor or the segmented steel corridor in the steel corridor 5, so that the installation of the two can be positioned. A clamp 12 is installed on the free end of the retaining frame 18, and the rods in the steel corridor 5 are embedded in the annular area of the clamp 12. The two are fixedly connected by bolts and another clamp 12. The clamping mechanism clamps the rods of the steel corridor 5 through the frame body 9 and the retaining frames 18, so that the steel corridor 5 and the lifting frame 3 temporarily become a whole, thereby improving the load resistance of the steel corridor 5 during hoisting.

[0040] Preferably, the control mechanism is a scissors-type structure, and two guide grooves respectively matched with the frame body 9 are provided on the side walls of the connecting frame 10. A sliding seat matched with the guide groove is integrally formed on the frame body 9, and a guide wheel matched with the guide groove is installed on the sliding seat, which can ensure that the frame body 9 moves smoothly in the guide groove. The scissors-type structure is connected to the two frames 9, and the two frames 9 can be controlled to move away from or towards each other through the scissors-type structure.

[0041] Preferably, the control mechanism can also be two hydraulic telescopic rods 16 respectively connected to the frame 9, and the main body of the hydraulic telescopic rod 16 is fixed in the guide groove. Not shown in the drawings.

[0042] In some technical solutions of the present invention, a plurality of mounting seats 15 corresponding to the retaining frames 18 are installed on the side walls of the frame 9, and a positioning mechanism for controlling the vertical or horizontal movement of the mounting seats 15 is provided in the frame 9. The positioning mechanism is two hydraulic telescopic rods 16 arranged in pairs, and the main bodies of the hydraulic telescopic rods 16 are rotatably arranged on the frame 9. A driving motor connected to the rotating shaft of the hydraulic telescopic rod 16 is installed on the frame 9, and the driving motor is a servo motor. The telescopic end of the hydraulic telescopic rod 16 is hinged to the mounting seat 15 through a pin shaft. The design of the above structure can ensure that the clamping mechanism automatically adapts to the position deviation of the rods of the steel corridor 5, and the inclined rods in the steel corridor 5 can also be clamped to prevent the rods from twisting under the clamping of the clamping structure, affecting the strength of its own steel structure, and ensuring uniform clamping force.

[0043] In some technical solutions of the present invention, the cage 18 is rotatably arranged on the side wall of the mounting seat 15, and a blocking mechanism 17 for controlling the deflection of the cage 18 is arranged on the mounting seat 15. The blocking mechanism 17 is a ratchet structure installed between the mounting seat 15 and the rotating shaft of the cage 18, which can prevent itself from rotating in the reverse direction after the position of the cage 18 is adjusted, improve the stability of the cage 18 during its own movement, dynamically lock the position of the cage 18 during the lifting process, and prevent deviation.

[0044] In some technical solutions of the present invention, the crawling mechanism includes a mounting frame 8 installed on the fixed end of the clamping mechanism. The mounting frame 8 is integrally formed with the connecting frame 10. A through groove is vertically opened on the side wall of the mounting frame 8, and a part of the lifting frame 3 is embedded in the through groove. Roller structures 11 in contact with the outer side wall of the lifting frame 3 are installed on two opposite side walls of the through groove. The clamping mechanism can move along the lifting frame 3 through the roller structures 11 in the crawling mechanism, which can reduce the moving friction and improve the smoothness of the operation of the above structure.

[0045] In some technical solutions of the present invention, a locking rod 21 is installed at the bottom of the through groove. Limiting rods 19 are rotatably arranged at both ends of the locking rod 21. A plurality of blocking blocks 4 are installed on the side wall of the lifting frame 3 along its extending direction. An adjusting structure for controlling the two limiting rods 19 to rotate counterclockwise is arranged in the locking rod 21. The locking rod 21 cooperates with the blocking blocks 4 through the limiting rods 19 and realizes segmented locking or release under the restriction of the two-way push rod 20, and gradually adjusts the height of the steel link corridor 5.

[0046] In some technical solutions of the present invention, a two-way push rod 20 is arranged in the locking rod 21. Locking holes are opened at the rotation centers of the two limiting rods 19, and limiting blocks adapted to the locking holes are installed on the telescopic ends of the two-way push rod 20. The rotation of the limiting rods 19 is controlled by the two-way push rod 20 in the locking rod 21 and is clamped into the locking holes opened at the rotation centers of the limiting rods 19, so as to lock the clamping mechanism on the lifting frame 3 and ensure the smooth climbing or descending of the above structure.

[0047] In some technical solutions of the present invention, a plurality of stabilizing frames 2 are detachably arranged between the two lifting frames 3. A lifting mechanism for driving the stabilizing frame 2 to lift along the extending direction of the lifting frame 3 is arranged on the side wall of the stabilizing frame 2. The stabilizing frame 2 can reinforce the lifting frame 3 by moving along the extending direction of the lifting frame 3 through the lifting mechanism, ensure the stable distance between the two lifting frames 3, and reduce shaking. At least two stabilizing frames 2 form a multi-point support between the two lifting frames 3, enhancing the overall torsional resistance.

[0048] In some technical solutions of the present invention, the distance between any two adjacent blocking blocks 4 is adjustable. The design with adjustable distance between the blocking blocks 4 can adapt to the support requirements of link corridors with different spans. The blocking blocks 4 are detachably installed on the side wall of the lifting frame 3 through bolt parts 13.
