The lifting board safety device solves the problems in the prior art, is safe and reliable, has simple mechanism, and can effectively detect the mounting state of the lifting board.
Description
Technical field
The utility model relates to escalator or moving sidewalk.
Background technology
In the prior art, the drive motor of escalator or moving sidewalk all disposes the boarding plate, so that the passenger has enough basing oneself upon and evacuation space, the below of boarding plate is the machine room upper or the machine room lower of escalator or moving sidewalk, and its inside is provided with mechanical parts such as drive motor, control housing, operation board.When escalator or moving sidewalk normally used, every block of boarding plate should be in normal installing condition, and both correctly closure was covered in above the machine room lower.But, if escalator or moving sidewalk are in use, there is the boarding plate to be in improper installing condition, failing correctly, closure is covered in above the machine room lower, can cause so the passenger in taking process, fall on machine room lower, cause serious injury and consequence.
The utility model content
For overcoming above-mentioned shortcoming, the purpose of this utility model be to provide a kind of safe and reliable, mechanism simple and can effectively detect the boarding plate safety device of the installing condition of boarding plate.
In order to reach above purpose, the technical solution adopted in the utility model is: a kind of boarding plate safety device, be used to detect the installing condition that is covered in the boarding plate on escalator or the moving sidewalk machine room upper metal truss, it comprises the switch mounting bracket that is arranged on the metal truss of described boarding plate below, being installed on being used on the described switch mounting bracket controls the spring arm switch of the motor of described escalator or moving sidewalk machine, described spring arm switch have an elastomeric spring arm that can swing up and down and with corresponding first mode of operation in this spring arm position and second mode of operation, under described first mode of operation, the lower surface of the spring arm of described spring arm switch and described boarding plate offsets, and described motor is opening; Under described second mode of operation, the spring arm freedom of described spring arm switch is extended upward, and described motor is closed condition.
Preferably, a plurality of spring arm switches are installed on the switch mounting bracket, adopt a plurality of spring arm switches to increase safety performance, prevent from when a spring arm switch breaks down, to cause the malfunctioning of whole device.
Further, described boarding plate comprises a plurality of boarding plates unit, and the metal truss of each below, described boarding plate unit is provided with the switch mounting bracket, on the described switch mounting bracket spring arm switch is installed.
Further, described switch mounting bracket and described metal truss removably connect, and described spring arm switch and described switch mounting bracket removably connect.
Owing to adopted technique scheme, therefore the utility model novel structure, safe and reliable, install convenient, can effectively detect the installing condition of boarding plate, thereby stop the situation that boarding plate abnomal condition in use appears in escalator or moving sidewalk, provide more failure-free safety assurance to the passenger.
Description of drawings
Accompanying drawing 1 is the running condition reference diagram of a kind of boarding plate of the utility model safety device, has shown mainly among the figure that spring arm switch (dotted line) before the boarding plate is installed installs the state of (solid line) afterwards with the boarding plate;
Accompanying drawing 2 is along the cutaway view of A-A in the accompanying drawing 1.
Wherein: 1, boarding plate; 2, metal truss; 3, switch mounting bracket; 4, spring arm switch; 5, bolt of rear end plate; 6, bolt of rear end plate.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby protection domain of the present utility model is made more explicit defining so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that.
Referring to accompanying drawing 1 and accompanying drawing 2, a kind of boarding plate safety device, be used to detect the installing condition of the boarding plate 1 on the metal truss 2 that is covered in escalator or moving sidewalk machine room top, it comprises by bolt of rear end plate 5 and detachably is installed in switch mounting bracket 3 on the boarding plate 1 below metal truss 2, be installed on the spring arm switch 4 that boarding plate 1 bottom on the switch mounting bracket 3 is used to control the motor of escalator or moving sidewalk machine by bolt of rear end plate 6, spring arm switch 4 have an elastomeric spring arm that can swing up and down and with corresponding first mode of operation in this spring arm position and second mode of operation, adjust the installing condition of spring arm switch 4, make it satisfy the required satisfied angle requirement of spring arm switch 4 actions.Under first mode of operation, the lower surface of the spring arm of spring arm switch and boarding plate 1 offsets, and motor is opening; Under second mode of operation, the spring arm freedom of spring arm switch is extended upward, and motor is closed condition.
Below describe the principle of work of a kind of boarding plate safety device in the present embodiment in detail.
Referring to accompanying drawing 1, under first mode of operation (solid line is represented part among the figure), be under the normal operation, boarding plate 1 covers on the metal truss 2, self gravitation by boarding plate 1 makes the spring arm of spring arm switch 4 be fixed to the position shown in the solid line in the accompanying drawing 1, spring arm switch 4 passes to control system with working signal, and by control system control motor normal operation, escalator or moving sidewalk can normally move.
Under second mode of operation (dotted line is represented part among the figure), be that boarding plate 1 does not cover under the state of metal truss 2, the spring arm of spring arm switch 4 relies on the elastic reset action to swing and signal is passed to control system in the top mutually, thereby control escalator or moving sidewalk are out of service.Have only after the correct once more installation of boarding plate 1,4 actions of spring arm switch, escalator or moving sidewalk can normally move.
Here be not difficult to find out, also can adopt the mode that a plurality of spring arm switches are installed below a boarding plate to increase the safety performance of boarding plate safety device, thereby can prevent from when a spring arm switch breaks down, to cause the malfunctioning of whole device; In addition,, can on the metal truss below each boarding plate unit, the switch mounting bracket be set respectively for the escalator with polylith boarding plate or the situation of moving sidewalk, and on each switch mounting bracket the mounting spring arm switch.
By above-mentioned embodiment, be not difficult to find out that the utility model is that a kind of safe and reliable, mechanism is simple and can effectively detect the boarding plate safety device of the installing condition of boarding plate.
Abovely the utility model is described in detail in conjunction with embodiment; only be explanation technical conceive of the present utility model and characteristics; its purpose is to allow the people that is familiar with this technology understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of being done according to the utility model spirit change or modify, and all should be encompassed in the protection domain of the present utility model.
