[0011] The following combines the drawings and embodiments to further describe the specific embodiments of the present utility model. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0012] The technical solution specifically implemented by the present utility model is:

[0013] As Figure 1 shown, an elevator traction device includes a traction machine assembly and further includes an annular support frame 1. The traction machine assembly is installed on the top of the annular support frame 1 through a support beam assembly. Two main connecting frames 2 are fixed on the top of the annular support frame 1. The two main connecting frames 2 are symmetrically arranged with respect to the center line of the annular support frame 1. Two opposite side edges of each main connecting frame 2 are vertically bent to form main connecting edges 3, and sub-connecting frames 4 are respectively arranged on both sides of each main connecting frame 2. The sub-connecting frame 4 includes a first sub-connecting edge 5 and a second sub-connecting edge 6 which are integrally connected. There is an included angle between the first sub-connecting edge 5 and the second sub-connecting edge 6. The first sub-connecting edge 5 is fixedly connected to the main connecting edge 3, and a connecting hole 7 for connecting with the shaft wall of the elevator hoistway is provided on the second sub-connecting edge 6.

[0014] By adopting the above scheme, when installing an elevator traction device of the present utility model: first, fix the main connecting frame 2 on the top of the annular support frame 1, then make the first sub-connecting edge 5 of the sub-connecting frame 4 abut against and fixedly connect with the main connecting edge 3 of the main connecting frame 2, then fixedly connect the second sub-connecting edge 6 of the sub-connecting frame 4 to the shaft wall of the circular elevator through the connecting hole 7, and finally install the traction machine assembly on the annular support frame 1 through the support beam assembly, thereby completing the installation of the traction device.

[0015] Further, the included angle between the first sub-connecting edge 5 and the second sub-connecting edge 6 is an acute angle, and a triangular reinforcing rib 8 is provided between the first sub-connecting edge 5 and the second sub-connecting edge 6. By adopting the above scheme, the stability between the first sub-connecting edge 5 and the second sub-connecting edge 6 is enhanced, and the anti-deformation ability of the sub-connecting frame is improved.

[0016] Further, the support beam assembly includes two support beams 9 arranged in parallel.

[0017] Further, a reinforcing beam 10 is fixedly located below the support beam 9 in the annular support frame 1, and the reinforcing beam 10 is perpendicular to the support beam 9. By adopting the above solution, the overall structural strength of the annular support frame 1 can be improved.

[0018] Further, the traction machine assembly includes a machine base 11, a reduction motor 12, and two groups of drive drums 13, and an L-shaped shield 14 is connected to the machine base 11 on the outside of the drive drum 13. By adopting the above solution, the protection of the drive drum 13 can be achieved.

[0019] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
