[0049] In the power side bottoming cases of Embodiment One and Embodiment Two, two different situations are proposed that the guide wheel set 80 of the hoisting car 90 is respectively located at the top and bottom of the car 90, and the corresponding guide wheel set layout under different situations.

[0050] In Embodiment One and Embodiment Two, in addition to the power mechanism of the side bottoming, only the support frame 70 needs to be laid in the shaft above the car 90, and the necessary components such as the guide wheel set and the rope clamp assembly 50 are centrally installed and laid by the support frame 70, so that the overall components are simplified, reasonable and compact.

[0051] As shown in Figure 4 , the main machine power winding and unwinding assembly 10 is also provided with a guide wheel 20, the axial direction of which is parallel to the axial direction of the main machine shaft 12, and the guide wheel 20 is located obliquely above the main machine shaft 12. The steel belt 30 wound on the main machine shaft 12 is led out upward after passing through the guide wheel 20.

[0052] In this embodiment, by providing the guide wheel 20 on the main machine power winding and unwinding assembly 10, the steel belt 30 is wound and led out through the guide wheel 20, so as to ensure the constant out-rope point of the steel belt 30, thereby eliminating the need for the layout of the guide pulley in the shaft and helping to ensure the utilization rate of the shaft.

[0053] The main machine power winding and unwinding assembly 10 comprises an inverted U-shaped rack 13, the main machine shaft 12 is rotatably installed between the two side walls of the rack 13, the main machine shaft 12 is driven to rotate by the end driving power 11, the rack 13 is provided with a guide wheel seat 21 on the top surface, and the guide wheel 20 is rotatably installed on the guide wheel seat 21.

[0055] During installation and layout, the left or right installation of the guide wheel 20 relative to the main machine power winding and unwinding assembly 10 can be adjusted through the guide wheel seat 21 according to actual installation requirements, which is convenient to use.

[0056] As shown in Figure 5 , a circumferential groove is formed in the circumferential direction on the guide wheel 20, the width of the circumferential groove matches the width of a single steel belt 30, and the steel belt 30 is led out by fitting the circumferential groove wall surface, and the circumferential groove limits the out-rope position of the steel belt 30 on the guide wheel 20, thereby effectively ensuring the constant out-rope point of the steel belt 30 after being led out through the guide wheel 20, and ensuring the stable and smooth operation of the steel belt 30.

[0057] As Figure 6 shown, the main shaft 12 is sleeved with an even number of baffle plates 14 along the axial direction, the baffle plates 14 are paired two by two, and the paired baffle plates 14 form a limiting space for winding the corresponding steel belt 30; during the winding of the steel belt 30, the baffle plates 14 on both sides guide and limit the winding of the steel belt 30, preventing the steel belt 30 from deviating during operation, effectively ensuring the reliability, stability and smoothness of the steel belt 30 winding, and ensuring safety.

[0060] In this embodiment, the steel belt 30 is used as the transmission medium, and since the thickness of the steel belt 30 is much smaller than the diameter of the steel wire rope under the same load, it has a natural advantage in reducing the diameter of the winding drum and the wheel set; through the thickness advantage of the steel belt 30, the flat structure 122 on the main shaft 12 is combined with the structure of the pressing block 15 to reliably and smoothly fix the end of the steel belt 30, and the overall structure is compact, which can also match the winding of the steel belt 30 on the main shaft 12.

[0064] In the embodiment, the surface of the pressing block 15 away from the planar structure 122 is located on the same circumferential surface as the circumferential wall surface of the main shaft 12, and the split shaft is formed by the cooperation of the pressing block 15 and the main shaft 12, and the effect of the steel belt 30 after winding is ensured by the outer circumference located on the same circumferential surface.

[0065] In the embodiment, the groove 121 can be provided on the circumferential surface of the main shaft 12 between the edges of the planar structure 122, and the width dimension of the groove 121 is matched with the width dimension of the steel belt 30; the two baffles 14 are installed at the edges of the groove 121 on both sides.

[0066] The depth of the groove 121 is limited, and in actual operation, the initial winding of the steel belt 30 on the main shaft 12 is positioned by the groove 121, and after the baffle 14 is installed, the winding of the steel belt 30 is limited by the baffle 14.
