Abstract
The utility model relates to the technical field of lifts, in particular to a linear handrail driving device of an escalator. The linear handrail driving device comprises a host machine and further comprises a driving sprocket wheel and at least three sets of driving wheel mechanisms arranged side by side, wherein each set of the driving wheel mechanism comprises a support wheel and a pressure wheel which are oppositely arranged with each other; each pressure wheel is in friction contact with a friction layer in the top surface of a handrail; each support wheel is in support contact with the bottom surface of the handrail; the host machine is in driving connection with the driving sprocket wheel through a chain; and the driving sprocket wheel is in driving connection with the pressure wheel through a chain. By adoption of the linear handrail driving device of the escalator, in such a structure, the handrail is unnecessary to bend in the process of operating; cracks on the surface of the handrail can be reduced; the service life of the handrail is greatly prolonged; furthermore, the problems of insufficient driving force and slip can also be effectively solved; and the operation synchronism of the handrail and the escalator is increased.
Description
Technical field:
The utility model relates to the elevator technology field, relates in particular to a kind of staircase straight line hand strap driving device.
Background technology:
Staircase is a kind of circular flow step that has; The fixedly driven by power equipment of conveying people is used for tilting up or down; Its structure is mainly by step, step driving unit, driving host, drive disk assembly, nervous device, armrest system, metal construction, step roller track, cover plate, fishback, safety device and the electrical part parts that grade are formed up and down; Has continuous working; The characteristics that transportation volume is big are widely used in the vertical transport of the public places such as subway, light rail, station, airport, harbour, shop and mansion that the stream of people concentrates.
Existing staircase; General adopt traditional macrobending frictional wheel actuating device to drive handrail, not only be easy to generate the not enough or skidding of propulsive effort, and during operation and the nonsynchronous phenomenon of staircase; And when operation, need crooked back and forth handrail; And handrail is processed by elastomeric material, and curving movement makes handrial belt produce be full of cracks easily, has shortened handrail service life greatly.
The utility model content:
The purpose of the utility model is to the deficiency of prior art a kind of staircase straight line hand strap driving device to be provided; Do not need crooked handrail during its operation; Can reduce handrial belt and produce be full of cracks; Improve the service life of handrail greatly, also can effectively solve the not enough and problem of skidding of propulsive effort, improve the synchronism of handrail and staircase operation.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of staircase straight line hand strap driving device, it comprises main frame, it also comprises the drive wheel mechanism that drive sprocket and at least three groups are arranged side by side; Every group of drive wheel mechanism comprises an opposed support roller and a pinch roller each other, the end face internal friction layer wipe contact of said pinch roller and handrail, and said support roller supports the bottom surface that is contacted with handrail; Said main frame connects said drive sprocket through chain drive, and said drive sprocket connects said pinch roller through chain drive.
Said drive wheel mechanism is provided with spring regulating device.
Said support roller is connected with tightening device.
It also comprises guide wheel, and said main frame is walked around the guide wheel rear drive through chain and connected said drive sprocket.
The surface of said pinch roller is provided with wearing layer.
The utility model beneficial effect is:
The said a kind of staircase straight line hand strap driving device of the utility model, it comprises main frame, it also comprises the drive wheel mechanism that drive sprocket and at least three groups are arranged side by side; Every group of drive wheel mechanism comprises an opposed support roller and a pinch roller each other, the end face internal friction layer wipe contact of said pinch roller and handrail, and said support roller supports the bottom surface that is contacted with handrail; Said main frame connects said drive sprocket through chain drive, and said drive sprocket connects said pinch roller through chain drive.Adopt the staircase straight line hand strap driving device of said structure; Do not need crooked handrail during its operation; Can reduce handrial belt and produce be full of cracks; Improve the service life of handrail greatly, also can effectively solve the not enough and problem of skidding of propulsive effort in addition, improve the synchronism of handrail and staircase operation.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, the described a kind of staircase straight line hand strap driving device of the utility model, its structure is, and it comprises main frame 1, and it also comprises the drive wheel mechanism that drive sprocket 3 and at least three groups are arranged side by side; Every group of drive wheel mechanism comprises an opposed support roller 5 and a pinch roller 7 each other, the end face internal friction layer wipe contact of said pinch roller 7 and handrail 6, and said support roller 5 supports the bottom surface that is contacted with handrail 6; Said main frame 1 connects said drive sprocket 3 through chain drive, and said drive sprocket 3 connects said pinch roller 7 through chain drive.Further, said a kind of staircase straight line hand strap driving device also comprises guide wheel 2, and said main frame 1 is walked around guide wheel 2 rear drives through chain and connected said drive sprocket 3.Guide wheel 2 plays the effect of tensioning and guiding.Further, the surface of said pinch roller 7 is provided with wearing layer, can improve the friction force with handrail 6, and can reduce friction loss.Preferably, present embodiment adopts three groups of drive wheel mechanisms, certainly, also can select four groups, five groups or more drive wheel mechanism that organizes for use according to actual conditions more.
As preferred embodiment, said drive wheel mechanism is provided with spring regulating device, and said support roller 5 is connected with tightening device 4, and tightening device 4 is used for tension chain.Wherein, support roller 5 mainly plays a supportive role, and pinch roller 7 mainly provides the propulsive effort of handrail 6 operations, and pinch roller 7 leans on the regulating spring control apparatus to compress handrail 6.
The described a kind of staircase straight line hand strap driving device of the utility model; Its principle of work is, the main frame 1 of staircase is through the said drive sprocket 3 of chain drive, and drive sprocket 3 is through 7 work of chain belt dynamic pressure wheel; Pinch roller 7 applies a thrust in handrail 6 through pressing force of the spring; The high-abrasive material manufacturing is adopted on pinch roller 7 surfaces, with the friction of handrail 6 internal friction layers, upwards drives or drives downwards through the friction masterpiece.The said a kind of staircase straight line hand strap driving device of the utility model; Because do not need crooked handrail 6 during operation; Can reduce handrail 6 surface and produce be full of cracks, its propulsive effort can be followed and organized pinch roller 7 according to the hoisting depth corresponding adopted of staircase more and drive side by side, solves the problem of skidding that causes inadequately because of propulsive effort; This device is selected suitable speed ratio for use, can good synchronism be arranged with staircase.
The above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
