Detailed Description
The invention will now be further described with reference to the accompanying drawings.
Referring to fig. 1-7, the utility model relates to a cam disc arresting gear, including U type support, bottom plate, cam disc, transmission wire rope, braking wheel hub, friction disc, shift fork, compression spring, brake wire rope, be provided with bottom plate 2 on the bottom surface of U type support 1, two shift forks 7 are alternately set up on bottom plate 2, and two shift forks 7 adopt screw 14 to fix on bottom plate 2. The head of the shifting fork 7 is provided with a U-shaped groove, the brake steel wire rope 9 is fixed at the tail of the shifting fork 7, the bottom plate 2 is provided with two waist holes 21, one end of each of two movable pins 10 is respectively inserted into the corresponding waist hole 21, the other end of each movable pin 10 sequentially penetrates through the U-shaped groove of the shifting fork 7 and the movable end of the brake hub 5, the fixed end of the brake hub 5 is fixed on the bottom plate 2 by adopting a fixed pin 12, the inner side of the brake hub 5 is provided with a spring groove 51, two ends of a compression spring 8 are respectively placed in the spring grooves 51 of the two brake hubs 5, the friction plate 6 is stuck in the groove on the outer side of the brake hub 5, the cam plate 3 is covered outside the brake hub 5, the friction plate 6 is attached to or separated from the inner. The rolling bearing 33 of the cam plate 3 is arranged on the transmission pin 11, two ends of the transmission pin 11 are respectively arranged on the top surface and the bottom surface of the U-shaped bracket 1, and the transmission steel wire rope 4 is wound in the spiral groove 32 outside the cam plate 3.
The utility model discloses, in order to make brake wheel hub 5's stiff end and expansion end highly uniform, the bottom of brake wheel hub 5's stiff end is equipped with equal altitude packing ring 13.
The utility model discloses at the during operation, install in stand operating system, when cam disc 3 rotated, transmission wire rope 4 removed thereupon, and drive stand operating system goes up and down. When the cam plate 3 is in a locking state, the transmission steel wire rope 4 stops moving to brake the upright post lifting system.
