Abstract
The utility model discloses a stair breakage protecting device of an escalator. The stair breakage protecting device comprises a mounting supporting frame and a stroke switch which is arranged on the mounting supporting frame and can trigger an escalator control system to be shut down. A rotary rod capable of rotating in the mounting supporting frame is arranged in the mounting supporting frame in a penetrating mode, the two sides of the rotary rod are respectively provided with a plurality of vertical rods which stretch to stairs of the escalator and are separated from the stairs, a touch piece which touches the stroke switch after the rotary rod rotates is further arranged on the rotary rod, and an elastic lamp for clamping the rotary rod is further arranged on the mounting supporting frame. The stair breakage protecting device can stop operating of the escalator in time under the condition that the stairs are broken or collapse, and the personal safety of pedestrians is guaranteed. In addition, the stair breakage protecting device is simple in structure, low in production cost and suitable for being popularized.
Description
[technical field]
The utility model relates to a kind of staircase, more specifically says a kind of step fracture protecting device of staircase.
[background technology]
At present, staircase is applied to the occasions such as megastore, and the step of staircase exists the risk of being trampled fracture by pedestrian in the process of operation; but staircase in the market does not but have the post-rift fender guard of step; once step fracture, and staircase constantly moves, consequence is by hardly imaginable.
The utility model produces based on this kind of situation just.
[utility model content]
The utility model object is to have overcome the deficiencies in the prior art, and a kind of step fracture protecting device of staircase is provided, and guarantees safety.
The utility model is achieved through the following technical solutions:
A kind of step fracture protecting device of staircase; it is characterized in that: comprise and bracing frame is installed and is established the travel switch that can trigger staircase control system shutdown thereon; in described installation bracing frame, be equipped with the dwang that can rotate therein; be respectively equipped with in described dwang both sides and multiplely stretch to the step of staircase and keep the montant of spacing with described step; on described dwang, be also provided with the touching part of the travel switch described in touching after it rotates, on described installation bracing frame, be also provided with the elastic clip of the described dwang of clamping.
The step fracture protecting device of staircase as above, is characterized in that: described elastic clip is U-shaped elastic steel sheet.
The step fracture protecting device of staircase as above, is characterized in that: described elastic steel sheet is 65Mn spring steel.
The step fracture protecting device of staircase as above, is characterized in that: described dwang is square pole.
The step fracture protecting device of staircase as above, is characterized in that: described dwang is cold drawn hexagonal steel.
The step fracture protecting device of staircase as above, is characterized in that: described travel switch is rolling wheel type travel switch.
The step fracture protecting device of staircase as above, is characterized in that: described touching part comprises the disk being set on described dwang, and described disk is provided with groove, and the roller of described travel switch is placed in described groove.
The step fracture protecting device of staircase as above, is characterized in that: the spacing of the upper end of described montant and described step is 3mm.
The step fracture protecting device of staircase as above, is characterized in that: described montant is four.
Compared with prior art, the utility model can, in the situation that step occurs fracture or subsides, stop the operation of staircase in time, guarantees the safety of pedestrian's person.In addition, the utility model is simple in structure, and productive costs is low, is applicable to promoting.

[detailed description of the invention]
Below in conjunction with accompanying drawing, the utility model is further described:
A kind of step fracture protecting device of staircase; comprise and bracing frame 1 is installed and is established the travel switch 2 that can trigger staircase control system shutdown thereon; in described installation bracing frame 1, be equipped with the dwang 3 that can rotate therein; be respectively equipped with in described dwang 3 both sides and multiplely stretch to the step 4 of staircase and keep the montant 5 of spacing with described step 4; on described dwang 3, be also provided with the touching part 6 of the travel switch 2 described in touching after it rotates, on described installation bracing frame 1, be also provided with the elastic clip 7 of the described dwang 3 of clamping.Once step 4 occurs fracture or subside, step 4 can knock montant 5 downwards, the stressed and run-off the straight in montant 5 upper ends; thereby drive dwang 3 to rotate, in the time that dwang 3 rotates, touching part 6 touches travel switch 2; now control system is just sent shutdown signal, and staircase is out of service.So just guarantee the personal safety of pedestrian in the time that step occurs fracture or subsides.The effect of elastic clip 7 is to clamp dwang 3, prevents from that dwang 3 rotates and makes to touch part 6 under normal circumstances to touch travel switch 2.
Described elastic clip 7 is U-shaped elastic steel sheet.Described elastic steel sheet is 65Mn spring steel.65Mn spring steel superior performance, adopts its U-shaped elastic steel sheet of making can steadily clamp dwang 3.
Described dwang 3 is square pole.Described dwang 3 is cold drawn hexagonal steel.It is steadily to be clamped by elastic clip 2 that dwang 3 adopts the benefit of square pole, if adopt circular pin, may occur that slight vibrations just rotate and produce misoperation.Cold drawn hexagonal steel is standard form shaped steel, with low cost, and buying is convenient.Hexagonal steel can steadily be clamped by elastic clip 2, can in the time that step 4 collides montant 5, can rotate in time again.In the utility model, adopt the dwang 3 of hexagonal steel to there is good stability, the advantage that reaction sensitivity is high.
Described travel switch 2 is rolling wheel type travel switch.Described touching part 6 comprises the disk 61 being set on described dwang 3, and described disk 61 is provided with groove 61a, and the roller of described travel switch 2 is placed in described groove 61a.In the time that dwang 3 rotates, disk 61 is followed rotation, and disk 61 is in the process of rotating, and the roller of travel switch 2 is deviate from gradually in groove 61a, and is pressed by disk 61, and control path is connected like this, and control system is sent shutdown signal to staircase.
The spacing of the upper end of described montant 5 and described step 4 is 3mm.Described montant 5 is four.The spacing of the upper end of montant 5 and step 4 is set to 3mm, can guarantee that step 4 occurs fracture or subsides time shutting down in time in short range very much, also avoid from too near and because of factor generation misoperations such as vibrations.
