[0030] The following is a further description of specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is intended to facilitate understanding of the present invention and does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0031] according to Figures 1-12 As shown:

[0032] Steel hoist wheel system, including:

[0033] The pulley assembly 1 includes a pulley seat 11, a side guide column 12 and a bearing pulley 13. The pulley seat 11 includes an external connection hole 111, a limit center column hole 112 and a side sliding concave hole 113. The external connection hole 111 is provided at the left and right ends of the limit center column hole 112. The limit center column hole 112 includes a limit seat hole 1121 and a screw sliding hole 1122 arranged from top to bottom. The side sliding concave holes 113 are respectively provided at the left and right ends of the screw sliding hole 1122. The side guide columns 12 are respectively mounted on the left and right ends of the side sliding concave holes 113. The bearing pulleys 13 are respectively mounted on the front and rear ends of the pulley seat 11.

[0034] The screw system 2 is arranged in the pulley block 1 and includes a screw wheel seat 21, a screw 22, a nut 23, a needle bearing 24, a safety clip 25, a wire rope 26 and a limit head 27. The screw 22 includes a toothless sliding surface 221, a threaded tooth 222 and a wire rope screw through hole 223. The toothless sliding surface 221 and the threaded tooth 222 are arranged outside the wire rope screw through hole 223 from top to bottom. The screw wheel seat 21 includes a wheel seat internal thread 211 and a wheel seat through hole 212 arranged from top to bottom in the center. The screw wheel seat 21 is connected to the screw rod 22 through the threaded engagement of the wheel seat internal thread 211 and the threaded teeth 222. The nut 23 is threadedly connected to the top of the screw wheel seat 21. The needle bearing 24 and the limit head 27 are arranged at the top of the pulley seat 11 from top to bottom. The limit head 27 includes a limit wire rope hole 271 opened in the center. The wire rope 26 passes through the limit wire rope hole 271 and the wire rope screw through hole 223. The two ends of the wire rope 26 are U-shaped and respectively embedded in the safety clip 25.

[0035] Because the limit seat hole 1121 is complementary to the needle bearing 24, and the inner diameter of the needle bearing 24 is equal to the outer diameter of the toothless sliding surface 221, when the user uses the present invention, the needle bearing 24 is tightly mounted in the limit seat hole 1121 through complementarity, and the screw 22 can be clamped in the pulley block 1 for use without shaking around. In addition, the outer diameter of the safety clip 25 is larger than the inner diameter of the limit wire rope hole 271 and the inner diameter of the wheel seat through hole 212. After the wire rope 26 is fixedly clamped at both ends of the safety clip 25, the upward movement of the pulley block 1 is limited.

[0036] Because the inner diameter of the screw sliding hole 1122 is equal to the outer diameter of the toothless sliding surface 221, when the user uses the present invention, the equal diameters allow one end of the toothless sliding surface 221 of the screw 22 to be tightly embedded in the screw sliding hole 1122 without shaking around, which would affect the normal use of the present invention.

[0037] Because the outer diameter of the nut 23 is larger than the inner diameter of the screw sliding hole 1122 and the outer diameter of the top end of the screw wheel seat 21, when the user uses the present invention, after the nut 23 is threadedly connected to the thread teeth 222, the downward movement of the pulley group 1 can be limited, and the upward movement of the screw wheel seat 21 can also be limited.

[0038] Because the outer diameter of the safety clip 25 is larger than the inner diameter of the limiting wire rope hole 271 and the inner diameter of the wheel seat through hole 212, when the user uses the present invention, through the larger diameter, after the wire rope 26 is fixedly clamped by the two ends of the safety clip 25, the downward movement of the screw wheel seat 21 can be limited by the safety clip 25.

[0039] Because the inner diameter of the limit head 27 is larger than the inner diameter of the needle bearing 24, and the outer diameter of the safety clip 25 is larger than the inner diameter of the limit wire rope hole 271 and the inner diameter of the wheel seat through hole 212, when the user uses the present invention, through the larger diameter, after the wire rope 26 is fixedly clamped by the two ends of the safety clip 25, the upward movement of the limit head 27 is limited by the safety clip 25, and then the upward movement of the needle bearing 24 is limited by the limit head 27, and then the upward movement of the pulley block 1 is limited by the needle bearing 24, thereby achieving the limitation of the downward movement of the pulley block 1.

[0040] Because the diameter of the side guide column 12 is larger than the inner length and inner width of the side sliding recess 113, and the outer height of the side guide column 12 is smaller than the inner height of the side sliding recess 113, when the user uses the present invention, the larger diameter enables the external contact component to slide smoothly on the surface end of the side sliding group 3.

[0041] Because the pulley seat 11 is made of 304 stainless steel, which is the most widely used chromium-nickel stainless steel, as a widely used steel, it has good corrosion resistance, heat resistance, low-temperature strength and mechanical properties, and has good hot workability such as stamping and bending, without heat treatment hardening phenomenon (operating temperature -196°C ~ 800°C), and is corrosion-resistant in the atmosphere. It is suitable for food processing, storage and transportation, and has good processing performance and weldability. Therefore, the pulley seat 11 made of 304 stainless steel has good overall strength, heat resistance, corrosion resistance and good strength.

[0042] When the user uses the present invention, the user first places the screw system 2 in the pulley block 1, and then connects it to the external component through the external connection hole 111. Then, the user adjusts the U-shaped length of the wire rope 26 in the safety clip 25 according to the required length, thereby achieving preliminary adjustment of the length. Then, the user can further achieve the length adjustment of the present invention by twisting the screw wheel seat 21 up and down on the screw 22, and then achieve limit adjustment by correspondingly twisting the nut 23 up and down to contact the screw wheel seat 21. Then, the user connects it to the external component that needs to be moved through the screw wheel seat 21, thereby achieving the use of the present invention.

[0043] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
