Embodiment Construction
[0038] Such as Figure 1 to Figure 25Shown is a specific embodiment of a centrifugal throwing block type speed governor of the present invention, including a bracket 1, a rope wheel 2, a ratchet 3, a rope pressing and hitting plate assembly 4, a limit switch 5, a first throwing block component 6, a second Get rid of block parts 7, get rid of block connecting rod 8 and adjust screw rod 9. Let the sheave 2 and the ratchet 3 be coaxially arranged side by side and erected on the support 1 through the sheave shaft 21, the first bearing structure 22 is arranged between the sheave 2 and the sheave shaft 21, and the second bearing structure is arranged between the ratchet 3 and the sheave shaft 21. Two bearing structures 31, a ratchet assembly 32 and a pressing pawl assembly 33 that cooperate with the ratchet 3 are arranged on the sheave 2. The rope-pressing plate assembly 4 specifically includes a rope-pressing bracket 41, a rope-pressing plate 42, a plate-beating part 43, a connect...

The invention discloses a centrifugal block throwing type speed governor comprising a support, a rope wheel, a ratchet wheel, a rope pressing and board striking assembly, a limiting switch, a first block throwing part, a second block throwing part, a block throwing connection rod and an adjustment screw. The rope wheel and the ratchet wheel are erected on the support through a rope wheel axle. The first block throwing part is installed on the rope wheel through a third bearing structure and is provided with a square-head screw facing a rim of the rope wheel. The second block throwing part is installed on the rope wheel through a fourth bearing structure and is provided with an elastic part facing the middle portion of the rope wheel. The two ends of the block throwing connection rod are correspondingly connected with the first block throwing part and the second block throwing part. The upper end of the adjustment screw is connected with a first connection plate. The lower end of the adjustment screw penetrates a through hole in a rope wheel connection table. The adjustment screw is sleeved with an adjustment spring. The centrifugal block throwing type speed governor has the beneficial effects of being simple in structure, low in cost, easy to implement and high in practicability, the problem that the centrifugal block throwing type speed governor makes abnormal sounds in the operation process of an elevator can be effectively solved, and the elevator taking comfort is improved.
Description
technical field [0001] The invention relates to an elevator overspeed governor, in particular to a centrifugal throwing block type overspeed governor. Background technique [0002] In recent years, the structure and technology of elevator speed governor devices have been developed rapidly. At present, the most used speed governors are mainly pendulum speed governors and centrifugal speed governors, especially centrifugal throwing block speed governors. It is the most widely used, and it plays an important role in guaranteeing the safe and stable operation of the elevator. The existing centrifugal throwing block type speed governor is mainly composed of a bracket, a rope wheel, a ratchet, a pawl, a pressing claw, two throwing block parts, a throwing block connecting rod, an adjusting screw, a pressing rope and a plate assembly, and a limit switch. composition. The centrifugal throwing block type speed governor uses the principle that the rotating centrifugal force increases...
