Abstract
The utility model discloses a device for protecting a drive chain of an escalator, which comprises a travel switch (1), a switch mounting plate (2), a fracture-resistant chain oscillating deck (3) and a sliding block (4). The limit switch (1) is fixed on the switch mounting plate (2); the fracture-resistant chain oscillating deck (3) is flexibly connected with the switch mounting plate (2) by a bolt (5) and can rotate around the bolt (5); the switch mounting plate (2) is installed on the a girder (6) of the escalator; and the sliding block (4) is mounted on the fracture-resistant chain oscillating deck (3) and connected with a drive chain (7) of the escalator. The device can automatically cut off the safety loop of the escalator to brake and stop the escalator within a specified distance when the drive chain of the escalator is too loose or fractured, thereby ensuring the safe running of the escalator.
Description
Technical field
The utility model relates to the driving chain fender guard of a kind of fender guard of escalator, particularly a kind of escalator.
Background technology
Escalator is in operation owing to (non-artificial) automatic velocity variations can take place and along with the period of service of escalator is long, the phenomenon of overrelaxation and even fracture can appear in the chain drive-belt of escalator, and serious threat is to the safe operation of escalator.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of escalator driving chain fender guard; the safety return circuit of escalator can appear cutting off automatically under the situation of overrelaxation or fracture at chain drive-belt in this device; escalator is stopped, ensure the safe operation of escalator.
For solving the problems of the technologies described above the technical solution of the utility model: escalator driving chain fender guard.Comprise travel switch, switch adapter plate, anti-chain rupture oscillating deck and slide block, travel switch is fixed on the switch adapter plate, and anti-chain rupture oscillating deck is movably connected on the switch adapter plate by bolt and can rotates around bolt; The switch adapter plate is installed on the truss of escalator; Slide block is installed on the anti-chain rupture oscillating deck and with the driving chain of escalator and is connected.
In the above-mentioned escalator driving chain fender guard, on anti-chain rupture oscillating deck, switch is housed and re-packs.
In the above-mentioned escalator driving chain fender guard, anti-chain rupture oscillating deck is the top that is positioned at the driving chain of escalator.
In the aforesaid escalator driving chain fender guard, slide block is the slide block of polyamine fat material.
Beneficial effect: compared with prior art, the utility model can occur at the chain drive-belt of escalator cutting off its safety return circuit automatically under the situation of overrelaxation or fracture, make escalator stopping of stipulating, thereby ensure the safe operation of escalator apart from inside brake.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
The specific embodiment
Embodiment.Shown in accompanying drawing 1,2, comprise travel switch 1, switch adapter plate 2, anti-chain rupture oscillating deck 3 and slide block 4, because 7 rubbing effects of driving chain of slide block 4 and escalator; Slide block 4 has been selected the polyamine fat slide block of polyamine fat material for use.Travel switch 1 is fixedly mounted on the switch adapter plate 2, and anti-chain rupture oscillating deck 3 is movably connected on the switch adapter plate 2 by bolt 5, and anti-chain rupture oscillating deck 3 can rotate around bolt 5; On anti-chain rupture oscillating deck 3, switch is installed and re-packs 8, switch adapter plate 2 is installed on the truss 6 of escalator, anti-chain rupture oscillating deck 3 is positioned at driving chain 7 tops of escalator, slide block 4 is between the driving chain 7 of anti-chain rupture oscillating deck 3 and escalator, the top of slide block 4 is fixedly mounted on the anti-chain rupture oscillating deck 3, and the bottom of slide block 4 is connected with the driving chain of escalator 7.
When driving chain 7 too relaxes sagging or unexpected fracture; polyamine fat slide block 4 and anti-chain rupture oscillating deck 3 move downwards; being installed in switch on the anti-chain rupture oscillating deck 3 re-packs and 8 has got to travel switch 1; travel switch 1 action, disconnection safety return circuit; the service brake action of escalator; make escalator concurrent signal that is out of order of stop in the distance of regulation, note down the fault content simultaneously, thereby reach the purpose of protection driving chain.
Embodiment of the present utility model is not limited to the foregoing description, all belongs within the protection domain of the present utility model in the various variations of making under the prerequisite that does not break away from the utility model aim.
