Embodiment Construction
[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0019] Such as figure 1 , figure 2 As shown, the present invention includes a mounting seat 1 , a rotating shaft 2 , a gland 3 , a rotating hand wheel 4 and a box body 5 , wherein the rotating hand wheel 4 is fixedly connected to the rotating shaft 2 .
[0020] Such as image 3 As shown, the mounting seat 1 is a channel steel structure, and a round hole 11 for passing through the rotating shaft 2 and a plurality of connecting holes 12 distributed around the round hole 11 are opened on the web of the channel steel structure. A mounting hole 13 for connecting the box body 5 is opened on one of the wing plates.
[0021] Such as Figure 4 As shown, the rotating shaft 2 is a cylindrical stepped shaft structure including a large-diameter end 21 , and the large-diameter end 21 of the rotating shaft 2 passes through the circular hole 11 of the mounting b...

The invention relates to a rotating hand wheel mechanism. The rotating hand wheel mechanism comprises an installing base and a rotating hand wheel. The rotating hand wheel is rotationally connected with the installing base through a rotating shaft. A box is arranged on the installing base. The box is internally provided with a scroll-shaped elastic metal belt. The end of the elastic metal belt extends out of the box and is fixedly connected with the rotating shaft. Due to the fact that the box is arranged on the installing base and internally provided with the scroll-shaped elastic metal plate, and the end of the elastic metal belt extends out of the box and is fixedly connected with the rotating shaft of the rotating hand wheel, when the rotating hand wheel is utilized for carrying out braking or relieving operation, the elastic metal belt can be pulled out of or contracted back into the box, and whether the rotating hand wheel is in a braking position or in a relieving position can be judged according to the length of the part, extending out of the box and wound on the rotating shaft, of the elastic metal belt.
Description
technical field [0001] The invention relates to a rotating hand wheel mechanism. Background technique [0002] Railway vehicles are generally provided with manual brakes which usually use a rotating hand wheel as the operating member for braking or releasing. The manpower brake of the railway vehicle is a parking brake, that is, it is used in the parking state. Before the vehicle is running, the manpower brake needs to be operated to the release position by rotating the handwheel. The NSW type manual brake commonly used in China can judge whether the manual brake is in the release state by whether the chain on the reel is slack, but some manual brakes driven by shafts are difficult to judge whether they are in the release position from the appearance. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a rotary handwheel mechanism capable of quickly judging whether the manual braking machine is in the braking...
