Description
Technical field
Escalator technical field is the utility model is related to, refers in particular to escalator haulage gear.
Background technology
Existing escalator trailer system it is complicated, it is complicated easily trigger failure, influence the operation of staircase
Safety, also increase the use cost of staircase.
The content of the invention
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided a kind of manufacturing cost is low, fault rate is few
Escalator haulage gear.
To achieve the above object, technical scheme provided by the utility model is：Escalator haulage gear, it includes
Pedal, pedal both sides are horizontal-extending formed with linking arm, and pulley groove is formed between adjacent linking arm, and pulley groove outer end is provided with lock
Plate, pulley being movably installed with pulley groove, main axle being provided with pulley center, main axle one end is arranged in pulley groove, main wheel
The axle other end is connected through jam plate with driving chain, and driving chain is made up of some groups of chain links, and chain link is by carrier bar and sprocket wheel structure
Into the carrier bar in each chain link is two pieces, is distributed in "eight" shape, and "eight" shape tip is on front side of rotation direction, two pieces
It is hinged between carrier bar end by chain axis connection, the chain rivet at the tip and the larger one end of previous group carrier bar of later group carrier bar, sprocket wheel
On chain rivet, pre-small post-large trapezoidal sprocket wheel guide groove is formed after connection between sprocket wheel and carrier bar.
Described main axle outer end is connected with carrier bar.
Described main axle outer end and corresponding chain axis connection.
Described main axle is integrated with chain rivet.
After using such scheme, the structure not being described in detail can be pacified the utility model using market conventional structure
Dress, by being improved to chain, is advantageous to the guiding of power chain using pre-small post-large trapezoidal sprocket wheel guide groove, makes transmission
The insertion of tooth is more accurate, and pulley is directly installed on pedal both ends, reduces the utilization rate of staircase spare and accessory parts, reduces staircase manufacture
Cost, while decrease fault rate.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Fig. 2 is link configuration schematic diagram of the present utility model.
Fig. 3 is sprocket wheel guide groove structure schematic diagram of the present utility model.
Embodiment
With reference to all accompanying drawings, the utility model is described in further detail, and preferred embodiment of the present utility model is：Ginseng
Accompanying drawing 1 is seen to accompanying drawing 3, and the escalator haulage gear described in the present embodiment includes pedal 1, the horizontal-extending shape in the both sides of pedal 1
Into there is linking arm 2, pulley groove is formed between adjacent linking arm 2, pulley groove outer end is provided with jam plate 3, is movably installed with pulley groove
Pulley 4, main axle 5 is provided with the center of pulley 4, the outer end of main axle 5 is connected with carrier bar 6, and the one end of main axle 5 is arranged on pulley
In groove, the other end of main axle 5 is connected through jam plate 3 with driving chain, and driving chain is made up of some groups of chain links, and chain link is by chain
Plate 6 and sprocket wheel 7 are formed, and the carrier bar 6 in each chain link is two pieces, is distributed in "eight" shape, and "eight" shape tip is positioned at operating
On front side of direction, it is integrated between two pieces of ends of carrier bar 6 by chain axis connection, main axle 5 with chain rivet, the tip of later group carrier bar 6
It is hinged with the chain rivet of 6 larger one end of previous group carrier bar, sprocket wheel 7 is arranged on chain rivet, and the outer end of main axle 5 connects with corresponding chain rivet
Connect, form pre-small post-large trapezoidal sprocket wheel guide groove 8 after connection between sprocket wheel 7 and carrier bar 6.The knot that the present embodiment is not described in detail
Structure can be installed using market conventional structure, by being improved to chain, be oriented to using pre-small post-large trapezoidal sprocket wheel
Groove is advantageous to the guiding of power chain, makes the insertion of driving cog more accurate, pulley is directly installed on pedal both ends, reduces staircase
The utilization rate of spare and accessory parts, staircase manufacturing cost is reduced, while decrease fault rate.
Embodiment described above is only the preferred embodiment of the utility model, not limits reality of the present utility model with this
Apply scope, therefore the change that all shape, principles according to the utility model are made, it all should cover in the scope of protection of the utility model
It is interior.
