Detailed Description
In order to make the aforementioned features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below, but the present invention is not limited thereto.
Refer to fig. 1 to 12
A steel rope anti-jumping device for pulleys with different diameters comprises fixing parts 20 which are arranged on two sides of a wheel shaft 11 of a pulley 10 and connected with a rotating shaft of the pulley, anti-jumping rods 30 are hinged to the other ends of the two fixing parts, anti-jumping assemblies 31 covering the upper portions of the pulley are arranged on the other ends of the anti-jumping rods, and adjusting mechanisms 40 which are connected with the anti-jumping rods and used for adjusting the distance between the anti-jumping assemblies and the pulley are arranged on the fixing parts.
in this embodiment, the fixing component includes a fixing rod 21, one end of the fixing rod is provided with an arc-shaped concave portion 22 and connected with an end cover 23, the end cover and the arc-shaped concave portion cooperate to form a shaft hole for being sleeved on the rotating shaft, and a friction plate 24 installed on the rotating shaft is arranged in the shaft hole. The friction plate can increase friction and prevent the fixed rod and the end cover from vibrating and losing working positions in actual work.
In this embodiment, the adjusting mechanism includes an adjusting rod 41 with one end hinged to the fixing component, a first waist-shaped hole 42 is formed in the upper portion of the adjusting rod along the length direction of the adjusting rod, a second waist-shaped hole 43 is obliquely formed in the anti-jump rod, an adjusting bolt 44 penetrating through the second waist-shaped hole and the first waist-shaped hole in the adjusting rod on the other side of the pulley is arranged in the first waist-shaped hole in the adjusting rod on one side of the pulley, and the adjusting bolt is in threaded connection with a locking nut 45.
