In the process of the rotation of the threaded rod driving the hoisting machine to move vertically in this utility model, it can automatically control the oil storage cylinder to supply oil and apply lubricating oil on the outer wall of the threaded rod to achieve the effect of self-lubrication. This not only reduces the frictional loss between the threaded rod and the slider, extends the service life of the equipment, but also ensures the smooth operation of the equipment, improves the working efficiency and reliability of the hoisting device.

[0021] 4. In this utility model, by providing a storage housing, when the pulley support is at the top, it is placed in the inner wall of the storage housing for storage, so that the pulley support is not affected by external factors and the service life of the pulley support is improved.

[0031] Embodiment:

[0032] Please refer to the attached Figure 1 -attached Figure 7 , the embodiment of the present invention provides a large steel frame structure hoisting device, including a base 1. The top of the base 1 is fixedly connected with a vertical steel frame 2, so that the base 1 provides a supporting and fixing effect for the vertical steel frame 2. The outer wall of the vertical steel frame 2 is slidably connected with a horizontal beam 4, so that during the vertical movement of the horizontal beam 4, stability is maintained. The inner wall of the horizontal beam 4 is slidably connected with a horizontal moving frame 5, so that the horizontal moving frame 5 moves horizontally along the top of the horizontal beam 4 to change the hoisting position. A hoisting machine 6 is arranged on the horizontal moving frame 5, and the large steel frame structure below is hoisted and moved through the hoisting machine 6, so as to achieve the purpose of moving the large steel frame structure to a specified position for installation.

[0033] The top of the base 1 is fixedly connected with a sliding track 3, so that the base 1 provides a fixing effect for the sliding track 3. The top of the sliding track 3 is fixedly connected with a motor 9 to maintain the stability of the motor 9 during operation. The output shaft of the motor 9 penetrates through the top of the sliding track 3 and is fixedly connected with a threaded rod 8. By starting the motor 9, the motor 9 drives the threaded rod 8 to rotate. The two ends of the threaded rod 8 are rotatably connected with the inner wall of the sliding track 3 to maintain the stability of the threaded rod 8 during rotation. A slide block 11 is threadedly connected to the outer wall of the threaded rod 8, and the top of the slide block 11 is fixedly connected with the bottom of the horizontal beam 4. Through the design of the slide block 11, the horizontal beam 4 moves vertically under the rotation effect of the threaded rod 8.

[0034] A support mechanism 7 is provided on the horizontal moving frame 5. The support mechanism 7 includes a receiving housing 701. The outer wall of the receiving housing 701 is fixedly connected to the outer wall of the horizontal moving frame 5, so that the receiving housing 701 moves simultaneously when the horizontal moving frame 5 moves. An arc-shaped rod 704 is slidably connected to the inner wall of the receiving housing 701, so that the arc-shaped rod 704 extends outward or retracts inward along the inner wall of the receiving housing 701. A pulley bracket 705 is slidably connected to the inner wall of the receiving housing 701 to maintain the stability of the pulley bracket 705 during movement. A shaft body 702 is rotatably connected to the inner wall of the receiving housing 701. A telescopic rod 703 is fixedly connected to the outer wall of the shaft body 702 to provide a fulcrum for the rotation of the telescopic rod 703. One end of the telescopic rod 703 is hinged to the outer wall of the arc-shaped rod 704, and the other end of the telescopic rod 703 is hinged to the outer wall of the pulley bracket 705. So that when the arc-shaped rod 704 moves inward under the extrusion effect, the telescopic rod 703 drives the pulley bracket 705 to extend outward through the rotation design. A ratchet 706 is fixedly connected to the outer wall of the shaft body 702, so that the ratchet 706 rotates simultaneously when the shaft body 702 rotates.

[0035] A viewing window 707 is fixedly connected to the outer wall of the receiving housing 701 to facilitate the observation of the inner wall of the receiving housing 701.

The top of the base 1 is fixedly connected to an arc-shaped push rod 710. The arc-shaped push rod 710 is used to push the arc-shaped rod 704 to contract inward, so that when the pulley bracket 705 is in contact with the ground, the arc-shaped rod 704 is completely retracted into the inner wall of the receiving housing 701.

[0036] A lubricating mechanism 10 is provided on the sliding track 3. The lubricating mechanism 10 includes an oil storage cylinder 102. The bottom of the oil storage cylinder 102 is fixedly connected to the outer wall of the sliding track 3, so that the sliding track 3 provides a supporting effect for the oil storage cylinder 102 to maintain the stability of the oil storage cylinder 102. An injection pipe 105 is fixedly connected to the outer wall of the oil storage cylinder 102. The outer wall of the injection pipe 105 penetrates and is fixedly connected to the inner wall of the sliding track 3, so that the lubricating oil can be discharged outward along the injection pipe 105. A pressing plate 104 penetrates and is slidably connected to the outer wall of the oil storage cylinder 102. One end outer wall of the pressing plate 104 is piston-connected to the inner wall of the oil storage cylinder 102. By horizontally moving the pressing plate 104, the inner wall of the oil storage cylinder 102 is squeezed to achieve the effect of injecting lubricating oil. The outer wall of the output shaft of the motor 9 is fixedly connected with a cam 101. The outer wall of the cam 101 is in contact with the other end outer wall of the pressing plate 104. When the motor 9 is started, the cam 101 is driven to rotate simultaneously, so that the outer wall of the cam 101 squeezes the outer wall of the pressing plate 104. The other end outer wall of the pressing plate 104 is fixedly connected to one end of a spring B 103. The other end of the spring B 103 is fixedly connected to the outer wall of the oil storage cylinder 102, and the force of the spring B 103 is used to drive the pressing plate 104 to reset outward, thereby achieving the effect of automatically injecting lubricating oil.

[0037] A usage method of a large steel frame structure hoisting device includes the following steps:

[0038] S1. Hoisting process:

[0039] S101: The lateral moving frame 5 is controlled by the staff to move, so that the lateral moving frame 5 moves along the inner wall of the cross beam 4, thereby changing the lateral position of the hoisting machine 6, and the hoisting machine 6 is moved to the top of the large steel frame structure to be hoisted;

[0040] S102. Then, the hoisting machine 6 is controlled to operate, so that the hoisting machine 6 lowers the hook provided at the bottom, and the staff cooperate to connect and fix the hook to the large steel frame structure to be hoisted, and the hoisting machine 6 is controlled to wind up the hook, so that the hoisted large steel frame structure moves upward to a suspended state;

[0041] S103. The moving frame is controlled to move, so that the moving frame drives the hoisting machine 6 and the hoisted large steel frame structure to move to the designated placement location, and the hoisting machine 6 is controlled to lower the hoisted large steel frame structure, thereby achieving the hoisting effect;

[0042] S2. Maintenance process:

[0043] S201. When maintenance of the hoisting machine 6 is required, the staff starts the motor 9, which drives the threaded rod 8 to rotate. The threaded rod 8 drives the moving block to move downward along the inner wall of the sliding track 3, causing the transverse beam 4 to move downward along the outer wall of the vertical steel frame 2, driving the transverse moving frame 5 and the hoisting machine 6 to descend, saving the time for the staff to climb;

[0044] S202. When the transverse beam 4 descends, the arc-shaped rod 704 provided at the bottom of the storage housing 701 is subjected to the extrusion effect of the arc-shaped push rod 710, causing the arc-shaped rod 704 to move upward. At the same time, the telescopic rod 703 is triggered to rotate, causing the telescopic rod 703 to drive the moving bracket to extend downward along the inner wall of the storage housing 701, so that the pulley provided at the bottom of the moving bracket contacts the ground, and the four groups of moving brackets provide an auxiliary support effect for the moving frame after it descends;

[0045] S203. At the same time, it cooperates with the ratchet 706 and the pawl 708 for self-locking to keep the moving bracket in an outward-expanded state when it is opened, and cooperates with the staff to control the rotation of the pulley provided at the bottom of the moving bracket, so as to separate the transverse moving frame 5 from the transverse beam 4;

[0046] S204. At the same time, during the process of the motor 9 starting to drive the threaded rod 8 to rotate, the cam 101 rotates simultaneously, causing the cam 101 to perform a piston extrusion movement on the inner wall of the storage cylinder. The oil stored in the inner wall of the storage cylinder is extruded and discharged along the injection pipe 105, so that during the rotation of the threaded rod 8, the lubricating oil stored in the storage cylinder is sprayed on the outer wall of the rotating threaded rod 8, achieving the effect of self-lubrication, preventing the situation that the friction between the threaded rod 8 and the moving plate is too large and a failure occurs after long-term use.

[0047] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
