In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance. For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances. The embodiments are described below according to the overall structure of the utility model.

[0026] The utility model discloses a kind of inorganic room elevator main machine hoisting system, be set in elevator shaft, the elevator shaft includes shaft top 1 and pit bottom 2, comprising:

[0027] Top plate assembly, the top plate assembly includes mounting plate 31 fixedly installed on the shaft top 1, lifting hook 32 and the guide wheel 33 corresponding with the lifting hook 32, the lifting hook 32 and the guide wheel 33 are all fixed on the mounting plate 31;

[0028] Hoisting device 4, the hoisting device 4 is installed on the pit bottom 2, steel wire rope 5 is wound on the hoisting device 4;

[0029] Main machine 6, the top of the main machine 6 is connected with hoisting wheel 7,

[0030] Among them, the steel wire rope 5 has first end 51 and second end 52, the first end 51 of the steel wire rope 5 is connected on the hoisting device 4, the second end 52 of the steel wire rope 5 is sequentially connected on the lifting hook 32 after passing the guide wheel 33, the hoisting wheel 7, so that the main machine 6 can be lifted by the steel wire rope 5 and the hoisting wheel 7.

[0031] By the above structure, the main machine hoisting system of the machine roomless elevator lifts the main machine 6 from the bottom of the elevator shaft smoothly by the cooperation of the steel wire rope 5 and the top plate assembly 3, and uses the lifting device 4. The lifting device 4 is installed on the bottom surface 2 of the bottom pit of the elevator shaft, can provide enough pulling force to lift the main machine 6, and the lifting hook 32 and the guide wheel 33 of the top of the shaft 1 play a guiding and stabilizing role, ensuring that the main machine 6 maintains a stable and accurate position during lifting.

[0032] Specifically, the top plate assembly 3 is fixedly installed on the top of the shaft 1, and the lifting hook 32 and the guide wheel 33 can be fixed on the mounting plate 31 by welding to ensure that the top plate assembly 3 as a whole can bear the weight of the main machine 6. Among them, the guide wheel 33 is located on the straight line extension of the position of the lifting hook 32, and the guide wheel 33 and the lifting hook 32 are located on the same vertical plane. The lifting device 4 is fixedly installed on the bottom surface 2 of the bottom pit, and the first end 51 of the steel wire rope 5 is connected to the lifting device 4. At the same time, the length of the steel wire rope 5 can cover the entire height of the main machine 6 lifting. After the second end 52 of the steel wire rope 5 is pulled out from the lifting device 4, it passes through the guide wheel 33 installed on the top of the shaft 1, ensuring that the steel wire rope 5 can smoothly slide on the guide wheel 33 and will not be stuck or misaligned; then, the steel wire rope 5 passes through the lifting wheel 7 connected to the top of the main machine 6, and finally connects with the lifting hook 32, so that the steel wire rope 5 can be wound by the lifting device 4 to drive the main machine 6 to lift upward.

[0033] Preferably, the mounting plate 31 is a steel plate, and is fixed to the top of the shaft 1 by expansion bolts. The thickened steel plate enhances the strength of the mounting plate 31, enabling it to withstand greater weight and tension, reducing the risk of deformation and damage, to ensure that it can adapt to the heavy load requirements of the elevator main machine 6 during hoisting. The mounting plate 31 is provided with a lifting hook 32 and a guide wheel 33, both of which are firmly fixed to the mounting plate 31, so that the steel wire rope 5 runs smoothly during hoisting. The use of expansion bolts makes the mounting plate 31 more stable when fixed to the top of the shaft 1, reducing the risk of displacement or loosening caused by gravity, thereby improving the stability of the hoisting system.

[0034] The lifting device 4 is installed on the bottom surface 2 of the bottom pit of the elevator shaft, and is firmly fixed to the bottom surface 2 of the bottom pit by expansion bolts. The lifting device 4 uses a winch as the driving force, and the winch drives the steel wire rope 5 to wind, thereby realizing the step-by-step lifting of the main machine 6. The bottom surface 2 of the bottom pit uses the fixing method of expansion bolts to ensure that the winch can maintain a stable position during the entire hoisting process and will not be displaced or tilted.

[0035] In the embodiment, the first end 51 of the steel wire rope 5 is fixed on the winch, and the second end 52 is fixed through the steel wire rope 5 clamp and the hook 32, so as to form a complete hoisting line. The steel wire rope 5 is sequentially guided through the top guide wheel 33 and the hoisting wheel 7 hoisted on the top of the main machine 6 after being drawn out from the winch. At the same time, the main machine 6 is connected with the steel wire rope 5 through the hoisting wheel 7 on the top, and the hoisting wheel 7 is fixed with the main machine 6 through the steel wire rope 5 clamp, so as to ensure that the main machine 6 will not fall off in the lifting process.

[0036] Up to now, the technical scheme of the utility model has been described in combination with the preferred embodiments shown in the drawings, but it is easy for those skilled in the art to understand that the protection scope of the utility model is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without deviating from the principles of the utility model, and the technical schemes after the changes or replacements will all fall within the protection scope of the utility model.
