Abstract
The invention discloses an escalator with a device for monitoring the fixing failure of a host machine. The escalator has the advantages of improving the safety of the escalator and eliminating hidden dangers.
Description
Technical Field
The invention relates to the field of escalators, in particular to an escalator with a device for monitoring fixing failure of a main machine.
Background
The escalator and the moving sidewalk are special equipment for conveying passengers, and the transmission mode between a power source (a main machine) and a driving shaft is chain transmission. The chain transmission is a flexible transmission, and the transmission structure is characterized in that the center distance between a driving wheel and a driven wheel is required to be within a designed range, and if the distance is small, the chain cannot be tensioned, the operation comfort is poor, and even the chain slips or fails. The chain is worn and elongated properly during use, and the position of the main machine needs to be adjusted at random to adapt to the change of the chain, so that the fixing holes of the base of the main machine are adjustable holes. In the escalator operation process, because the host computer receives the pulling force of chain and the vibrations that the operation produced all the time, if the locking torque of the fixing bolt of host computer fails to reach the requirement of regulation, the host computer can slide to the chain pulling force direction by a small margin, leads to the chain to sag, if fail in time to discover the adjustment, can cause very big potential safety hazard, leads to the serious casualty accident even.
This is where the application needs to be focused on.
Disclosure of Invention
The invention aims to provide an escalator with a monitoring host fixing failure device, which is high in safety.
In order to solve the technical problems, the invention provides an escalator with a device for monitoring the fixing failure of a host, wherein the most stressed far end of a base of the host is contacted with a detection switch, and the host moves or rotates to exceed a set value, so that the detection switch is triggered, and an alarm ladder stopping signal is sent.
The main machine moves forwards by the pulling force of the chain to exceed a set value, the detection switch detects that the moving distance exceeds the set value, the detection switch is triggered, and an alarm ladder stopping signal is sent.
The main machine moves left and right under the pulling force of the chain to exceed a set value, the detection switch detects that the moving distance exceeds the set value, the detection switch is triggered, and an alarm ladder stopping signal is sent.
The main machine moves beyond a set value due to the rotation of the chain under the action of the pulling force, the detection switch detects that the moving distance exceeds the set value, the detection switch is triggered, and an alarm elevator stopping signal is sent.
A device for monitoring the fixed failure of the main machine is additionally arranged on the escalator, and when the failure of the main machine reaches a preset range, a detection switch triggers an alarm, and the escalator stops to display faults.
The invention has the following advantages: the safety of the escalator is improved, and hidden dangers are eliminated.

Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1, in an escalator with a device for monitoring fixing failure of a main machine, a base of the main machine 1 is stressed to be in contact with a farthest end of a detection switch 2, 101 is a normal position of the main machine, the main machine 1 is under the tension of a chain, when a forward moving position 102 of the main machine reaches 5mm, the detection switch 2 is triggered, and the detection switch 2 is connected with a controller of the whole escalator to send an alarm stopping signal.
As shown in fig. 2, the second embodiment of the present invention provides an escalator with a device for monitoring fixing failure of a main machine, a base of the main machine 1 is stressed to a far end and is contacted with a detection switch 2, 101 is a normal position of the main machine, the main machine 1 is under the pulling force of a chain, when a leftward movement position 103 of the main machine reaches 5mm, the detection switch 2 is triggered, and the detection switch 2 is connected with a controller of the whole escalator to send an alarm stop signal.
As shown in fig. 3, a third embodiment of the present invention provides an escalator with a device for monitoring fixing failure of a main machine, a base of the main machine 1 is stressed to a far end and is contacted with a detection switch 2, 101 is a normal position of the main machine, the main machine 1 is under tension of a chain, when a rotating position 104 of the main machine reaches 1.5 degrees, the detection switch 2 is triggered, and the detection switch 2 is connected with a controller of the whole escalator to send an alarm stop signal.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
