Fig. 2 is the structural schematic diagram of part A in Fig. 1;
Fig. 3 is a kind of overall structure diagram for anti-chain dropping device that embodiment 2 provides.
In figure, 1, guide rail part;2, arc panel;21, fixed plate;211, connecting plate;22, chamfering;3, tensioning apparatus.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing, the present embodiment is not constituted to this
The limitation of utility model.
Embodiment 1:
The utility model embodiment 1 discloses a kind of anti-chain dropping device, as shown in Figure 1, the device is installed on guide rail
On component 1, chain one end is oriented to along 1 outer side edges of guide rail part and is driven, and anti-chain dropping device includes being located on the outside of chain to be used for
The arc panel 2 of fixed fracture chain, arc panel 2 use band steel guide rail bent into shape, guide rail part 1 outwardly side be it is semicircle and
Arc panel 2 and the semi-circular concentric.
As shown in Figure 1, guide rail part 1 slides be connected in truss in the horizontal direction, guide rail in order to be tensioned to chain
Tensioning apparatus 3 for outward pulling is installed, in the present embodiment, which is elastic stretching device on component 1
3.The tensioning apparatus 3 be the prior art, such as application No. is the Chinese utility model of CN201320332465.8 " escalator
Have disclosure in step chains Tensioning structure ", does not do excessively repeat herein.
As shown in Figure 1, arc panel 2 is fixed on guide rail part 1,2 inside of arc panel and the roller lateral surface of chain offset
It connects, 1 side of guide rail part has been connected by screw to two fixed plates 21, and arcuately plate 2 is arranged radially fixed plate 21, arc panel 2
It is connected to 21 outer end of fixed plate, in the present embodiment, 21 outer end of fixed plate is connected with the connecting plate 211 perpendicular with it, connecting plate
211 are connected to 2 outside of arc panel and are fixed by screw.When due to host operation, the pulling force on chain is very big, by the way that arc is arranged
The tightness cooperated between shape plate 2 and chain roller, so that chain is only capable of when host is run from arc panel 2 and guide rail part
It passes through and is driven between 1, and cannot be merely due to self weight disengages it from guide rail part 1, to prevent the chain of fracture from sliding into lower machine
Room.It can organize the chain for preventing fracture to slide at the first time, and safety is higher.
As shown in Fig. 2, in order to reduce the friction between chain and arc panel 2 make arc panel 2 deform after block chain, arc
The radius of plate 2 is greater than the radius at the semicircle position of guide rail part 1, and is respectively equipped with chamfering 22 on the inside of the both ends of arc panel 2, so that
Only intermediate position is abutted against with chain roller on arc panel 2, and 2 ~ 3 near both ends chain roller and 2 inside of arc panel are not
It abuts.
Embodiment 2:
The utility model embodiment 2 discloses a kind of anti-chain dropping device, and structure is substantially the same manner as Example 1,
The difference is that: as shown in figure 3, arc panel 2 is fixed on truss, when guide rail part 1 slides onto outermost end, in arc panel 2
Side is abutted against with chain.When normal work, 2 inside of arc panel is not abutted with chain, is reduced the resistance of chain drive, is reduced
Energy consumption;Chain is disconnected when falling, and tensioning apparatus 3 drives guide rail part 1 to slide onto outermost end, 2 inside of arc panel and chain phase outward
It abuts, prevents the chain of fracture from sliding.Its energy consumption is lower, and rub smaller, the longer life expectancy of chain and the device.
The above descriptions are merely preferred embodiments of the present invention, is not used in limitation the utility model, this field skill
Art personnel can make various modifications or equivalent replacements to the utility model in the essence and protection scope of the utility model,
This modification or equivalent replacement also should be regarded as falling in the protection scope of technical solutions of the utility model.
