Description
Technical field
The present invention relates to the parts technical field of escalator or mobile human row of channels, particularly relate to a kind of escalator stop mechanism.
Background technology
Along with the development of science and technology, various people's Working Life of giving provides facility also to develop thereupon, and escalator is exactly one of these amenities.It makes the trip of people more convenient, but there is also certain problem.During as escalator non-normal working, occur the phenomenon reversed sometimes, this brings certain danger to the people taking escalator.The cause of a lot of escalator accident is exactly driving in the wrong direction of its motor to have had report to confirm.Therefore, how addressing this problem is the focus that correlative technology field is studied.
The existing mechanism structure about solving escalator reverse is complicated, and price is higher, and occupy larger space, installation and maintenance are loaded down with trivial details, is unfavorable for promoting the use of on a large scale.Therefore, provide a kind of simple effectively, the escalator stop mechanism of anti-reverse that price is lower has great importance.
Summary of the invention
The problem to be solved in the present invention is that the existing mechanism structure about solving escalator reverse is complicated, and price is higher.
For solving the problems of the technologies described above, the technical solution used in the present invention is: provide a kind of escalator stop mechanism.Described escalator stop mechanism comprises electrical motor, transmission shaft, ratchet device and control system.
Described electrical motor and ratchet device are all electrically connected with control system.
Described ratchet device is fixedly connected with by transmission shaft with electrical motor, and the rotation direction of described ratchet device is identical with the rotation direction of described electrical motor.
Further, described control system comprises the speed sensor be arranged on ratchet device, and the running velocity of described ratchet device responded to by described speed sensor.
Preferably, described ratchet device is internal messing ratchet device.
Further, described control system also comprises annunciator.
Further, described escalator stop mechanism also comprises install bin, and described install bin is arranged on the outside of described electrical motor and ratchet device, and the inside face of the casing of described install bin is provided with acoustical panel.
The advantage that the present invention has and good effect are: escalator stop mechanism provided by the invention, has the function of anti-reverse, and structure is simple, and price is lower, is beneficial to and promotes the use of.Adopting ratchet device, effectively utilizing its braking effect to reach the effect of the anti-reverse of this escalator stop mechanism, simply effectively, without the need to increasing too much part.In addition, escalator stop mechanism provided by the invention, installs simple, is beneficial to routine inspection maintenance.

Detailed description of the invention
For a better understanding of the present invention, below in conjunction with detailed description of the invention and accompanying drawing, the present invention is conducted further description.
As depicted in figs. 1 and 2, a kind of escalator stop mechanism, comprises electrical motor 1, transmission shaft 2, ratchet device, control system and install bin.
Electrical motor 1 and ratchet device are all electrically connected with control system.Ratchet device is fixedly connected with by transmission shaft 2 with electrical motor 1, and the rotation direction of ratchet device is identical with the rotation direction of electrical motor.
Control system comprises and is arranged on speed sensor on ratchet device and annunciator, the running velocity of speed sensor induction ratchet device 3.
Install bin is arranged on the outside of electrical motor 1 and ratchet device, and the inside face of the casing of install bin is provided with acoustical panel.
In this detailed description of the invention, ratchet device is internal messing ratchet device 3, in other embodiments, can also be other forms of ratchet device.
Internal messing ratchet device 3 comprises support 31, foreign steamer 32, interiorly takes turns 33 and ratchet 34.Foreign steamer 32 is fixedly connected with support 31, and ratchet 34 is rotating is arranged on interior edge of taking turns the wheel card of 33, inside takes turns 32 and is fixedly connected with transmission shaft 2.Wheel card 321 edge of foreign steamer 32 evenly has groove tooth 322, and groove tooth 322 comprises straight line and camber line limit.Inside taking turns 33 is arranged in through hole, is flexibly connected with foreign steamer 31 by bearing.Ratchet 34 comprises circle wheel end and arc end, and circle wheel end is fixedly connected with arc end, one-body molded.Circle wheel end is rotatingly arranged on interior edge of taking turns the wheel card of 33, and arc end is taken turns 33 by reciprocating apparatuses such as springs be connected with interior, and the radian of the radian of the arc end of ratchet 34 and the arc-shaped edges of groove tooth 322 matches.
When using the stop mechanism of escalator provided by the invention, first the service direction of electrical motor 1 is set, afterwards internal messing ratchet device 3 is connected with electrical motor 1 by transmission shaft 2, makes the service direction of internal messing ratchet device 3 consistent with the service direction of electrical motor 1.As shown in Figure 2, the service direction of internal messing ratchet device 3 is cw.It is consistent that the pre-set velocity of internal messing ratchet device 3 and the normal speed of motor in control system are set.
When electrical motor 1 runs, drive wheel 33 and ratchet 34 in internal messing ratchet device 3 to move by transmission shaft 2, ratchet 34 slips over groove tooth 322, normally runs.Now, control system accepts the signal of speed sensor, judges that it is consistent with pre-set velocity.When electrical motor 1 go out these abnormal condition reverse time, inside take turns 34 and ratchet 34 also start to drive in the wrong direction, now, the arc end of ratchet 34 is stuck in groove tooth 322, and ratchet 34 stops operating, and makes interiorly to take turns 33 and stop operating, thus the running velocity of electrical motor 1 is declined until stop.Inside take turns in 33 processes stopped operating, its speed is transferred to control system by speed sensor, and control system detects that they are different from the speed preset, thus cuts off the power supply of electrical motor 1, makes it shut down.Meanwhile, control system starts annunciator, notifies that the operation of staff's electrical motor 1 occurs abnormal.
Above the specific embodiment of the present invention has been described in detail, but described content being only better embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the scope of the invention change and improve, and all should still belong within this patent covering scope.
