[0037] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0038] like Figure 1 As shown, a transversely arranged steel strip rope head structure of this embodiment includes a horizontally arranged support frame 1. A wheel seat 2 and a clamp seat 6 are sequentially installed on the support frame 1 along the horizontal direction. A reversing wheel 4 is installed on the wheel seat 2. A rope head clamp assembly 5 is installed horizontally through the clamp seat 6. The head of the steel strip 10, which is reversed from the reversing wheel 4 to the transverse direction, is fixed on the rope head clamp assembly 5.

[0039] In this embodiment, by using the reversing wheel 4, the end of the steel belt 10 is changed from vertical to horizontal, and combined with the rope head clamp assembly 5, the horizontal arrangement of the steel belt rope head structure is realized.

[0040] like Figure 2 and Figure 3 As shown, a shock absorber 3 is installed between the wheel seat 2 and the support frame 1. The shock absorber 3 includes steel plates 32 arranged at intervals on the upper and lower sides, and shock absorber pads 31 that are recessed in the circumferential direction are installed between the steel plates 32. Long studs 8 are installed through the wheel seat 2, the upper and lower steel plates 32 and the support frame 1, and the two ends of the long studs 8 are locked with tightening nuts 81.

[0041] In this embodiment, when installing the shock absorber 3 between the wheel seat 2 and the support frame 1, a long stud 8 structure that runs vertically through the wheel seat 2 is adopted. This allows the shock absorber 3 to not only provide shock absorption in the height direction, but also withstand the lateral force caused by the transverse arrangement of the rope head. The long stud 8 holds the wheel seat 2 and the support frame 1 together, thus avoiding the safety risk caused by the upper and lower steel plates 32 in the shock absorber 3 being pulled off by the lateral force.

[0042] The long stud 8 has a smooth rod in the middle, and the two ends of the long stud 8 that extend upward to the wheel seat 2 and downward to the support frame 1 are set as threaded parts 80, and the nuts 81 are locked onto the threaded parts 80.

[0043] In this embodiment, the middle part of the long stud 8 is set as a smooth rod part, which effectively avoids friction noise between the shaft and the hole. In addition, it can also restrict the position of the locking of the two ends of the tightened nut 81. The length of the smooth rod part effectively ensures the space between the wheel seat 2 and the support frame 1, ensuring the shock absorption effect of the shock absorber 3, and avoiding excessive locking of the tightened nut 81 under the condition of full thread, which would crush the shock-absorbing rubber pad and lose its buffering effect.

[0044] The wheel seat 2 is a U-shaped structure with an opening facing upward, and the two arms of the wheel seat 2 are outwardly turned to form horizontal flanges 21. The damping member 3 is installed between the bottom surface of the horizontal flanges 21 and the support frame 1, which helps to reasonably utilize the height space and reduces the installation height of the reversing wheel 4 relative to the support frame 1.

[0045] In this embodiment, the edges of the two horizontal flanges 21 are respectively downwardly turned and extended to form vertical flanges 22, and the damping member 3 is located inside the vertical flanges 22.

[0046] The damping member 3 includes at least two groups arranged side by side on the support frame 1. At least one group of damping members 3 is installed by a long stud 8 penetrating upward and downward, so as to bear lateral force. The upper and lower steel plates 32 in at least one group of damping members 3 are independently locked and fixed to the wheel seat 2 and the support frame 1 by short studs 9.

[0047] In this embodiment, the installation of multiple groups of damping members 3 in parallel effectively guarantees the damping effect and meets the damping requirements.

[0048] In this embodiment, the wheel shaft 41 at the end of the reversing wheel 4 is supported on the wheel seat 2, and a locking member 42 in an inverted U-shaped structure is downwardly buckled on the wheel shaft 41. The bottom end of the locking member 42 is inserted into the wheel seat 2, thereby achieving the installation of the reversing wheel 4.

[0049] In this embodiment, a groove can be formed on the circumferential wall surface of the reversing wheel 4 to limit the steel belt 10.

[0050] As shown in Figure 4 , Figure 5 The structure of the rope clamp assembly 5 includes a support rod 52 penetrating the clamp seat 6, and a rope penetrating block 57 is installed at the end of the support rod 52. The rope penetrating block 57 is located on the same side of the clamp seat 6 as the reversing wheel 4. A through opening 571 is formed in the rope penetrating block 57, and the steel belt 10 horizontally drawn out from the reversing wheel 4 extends into the small end of the opening 571 and out of the large end. Then, the steel belt 10 is reversely folded at the large end and extends out of the small end. The end of the steel belt 10 extending out of the small end is provided with a steel belt clamp 58. A wedge block 59 is pressed between the double-layer steel belts 10 inside the rope penetrating block 57. Figure 6

[0051] In this embodiment, in actual operation, the steel belt 10 is inserted into the small end of the rope penetrating block 57 and extends out of the large end. After the wedge block 59 is covered by the steel belt 10 from the large end, they are inserted back into the opening 571 of the rope penetrating block 57 together. The end of the steel belt 10 extends out of the small end and is pulled tight, and then the steel belt clamp 58 is installed. The steel belt 10 is pressed against the wedge surface between the wedge block 59 and the opening 571, and the installation of the end of the steel belt 10 on the rope clamp assembly 5 is completed.

[0052] ​In this embodiment, the steel strip clip 58 can be a structure that is fastened together with fasteners to prevent the steel strip 10 from loosening and retracting into the small end of the opening 571.

[0053] On the support rod 52 located on the other side of the clamp seat 6, opposite to the rope-threading block 57, a positioning block 51, a washer 54, an elastic element 53, and a washer 54 are sequentially mounted, and two locking nuts 55 are threaded and locked; a pin 56 is inserted radially on the support rod 52 adjacent to the outer side of the locking nut 55.

[0054] In this embodiment, the elastic element 53 on the support rod 52 provides a buffer elasticity for the rope end clamp assembly 5 that holds the end of the steel strip 10; the pin 56 is used to prevent the locking nut 55 from falling off.

[0055] The end of the support rod 52 is threadedly fitted to the rope-threading block 57; a through groove is provided on the wedge block 59, and a locking pin is installed horizontally through the rope-threading block 57 and the through groove to prevent the wedge block 59 from disengaging from the rope-threading block 57.

[0057] In this embodiment, other components, such as the drive power unit 7 and the guide wheel 40, can be arranged on the support frame 1 according to the overall layout of the elevator system, which helps to achieve a compact layout of the elevator system components.

[0058] This embodiment also proposes an elevator, including a car 30. The lifting of the car 30 is achieved by a steel belt 10, and the end of the steel belt 10 is fixed by the aforementioned horizontally arranged steel belt rope head structure.
