Problems solved by technology

However, since the long weight 1 is heavy, it is dangerous to rotate the weight at high speed based on centrifugal force
If the detection switch of the non-contact type has an electrical failure, it cannot work, which creates a problem of reduced safety

[0063] Figure 5 is a block diagram of a speed governor device for a passenger conveyance system according to a second embodiment of the present invention.

[0064] The speed governor device 31 of this embodiment differs from the first embodiment only in that: the structure of the rotating mechanism has an imaginary rotating body 33 and an imaginary rotating axis 32 . Other structures are almost the same as the first embodiment. Figure 5 in, with figure 1 The same parts as those of the first embodiment are denoted by like reference numerals, and their detailed descriptions are omitted. In addition, the same reference numerals are used for the same parts.

[0065] refer to Figure 5 , the rotation mechanism of the eccentric ring 13 has an imaginary axis of rotation 32 which is located at a distance from the base 14 on the outside.

[0066] The eccentric ring 13 has two elongated bores 34 a , 34 b arranged along a circular arc around the imaginary axis of rotation 32 . T...

[0076] Figure 6 is a block diagram of a speed governor device for a passenger conveyance system according to a third embodiment of the present invention.

[0077] The speed governor device 41 of this embodiment differs from the first embodiment only in that the structure of the rotating mechanism has an imaginary rotating body 43 and an imaginary axis of rotation 42 . Other structures are almost the same as the first embodiment. Figure 6 in, with figure 1 The same parts as those of the first embodiment are denoted by the same reference numerals, and their detailed descriptions are omitted. In addition, like reference numerals are used to explain the same parts.

[0078] refer to Figure 6 , the governor device 41 for the passenger transport system further includes two link mechanisms 46a, 46b, each of which is connected to the eccentric ring 13 at one end and to the base 14 at the other end. In addition, each link mechanism 46 a , 46 b has a longitudinal axis disposed ...

Abstract

The invention relates to an eccentric ring-shaped thin governor for a passenger transportation system, capable of being mounted in a narrow space located aside a belt pulley. The governor (11) for a passenger transportation system has a rotator (12a), a base (14) fixed to the rotator (12a), and an eccentric ring (13) rotatably fixed to the base (14) through a rotation mechanism (14a) and having the center of gravity at a position eccentric relative to the center of rotation of the rotator (12a). The base (14) and the eccentric ring (13) are connected together by a restoration mechanism (15) for imparting restoration force to the eccentric ring (13), and the restoration force acts on the eccentric ring (13) to direct it in the direction toward a restoration position. A restoration stopper (16) restrains the eccentric ring (13) to the restoration position.A detection switch (18) in contact with a cam profile (13a) of the eccentric ring (13) during operation of the eccentric ring (13) is provided near the eccentric ring (13), and a controller (20) stops the passenger transportation system by a signal from the detection switch (18).

Description

technical field [0001] The present invention relates to a governor device for a passenger transport system, which is provided on a drive device which drives the passenger transport system, such as a passenger conveyor or the like. Background technique [0002] Figure 7 It is a structural diagram of an ordinary governor device. Figure 8 and 9 Front and rear views, respectively, of a common governor device for a passenger transportation system such as a passenger conveyor (elevator or moving walkway). Figure 7 Among them, reference numeral 1 denotes a weight adapted to slide along the outer circumferential direction, and 2 denotes a spring body adapted to press the weight 1 with a predetermined pressure along the center direction of rotation. In addition, reference numeral 3 denotes a guide portion that guides the weight 1 and the spring body 2, 4 denotes a base for fixing the weight 1, the spring body 2, and the guide portion 3 thereto, and 5 denotes a detection switch ,...
