Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, an additional brake device for an escalator comprises a truss 1, driving devices 2 are arranged on two sides of an inner cavity of the truss 1, a lifting ladder 3 is connected to the outer surface of each driving device 2 in a transmission mode, safety pedals 4 are arranged on two sides of the top end of the truss 1, the inner wall of each safety pedal 4 is connected with the outer wall of the corresponding lifting ladder 3 in a clamping mode, a handrail 5 is fixedly installed at the top end of the truss 1, a sealing bag 6 is fixedly installed inside each safety pedal 4, and the inside of each sealing bag 6 is communicated with a trigger mechanism 7 fixedly installed on one side inside each safety pedal 4.

The triggering mechanism 7 in the safety step 4 is arranged to see mainly whether the escalator is moving upwards or downwards, and the safety step 4 is installed at the entrance of the escalator.

In the technical scheme, the outside of the sealing bag 6 is provided with a saw-toothed shape, and the saw-toothed sealing bag 6 is fixedly arranged in a gap between the lifting ladder 3 and the safety pedal 4.

The sealing bag 6 is made of a mixing polyurethane material, so that the sealing bag has good wear resistance and elasticity, the service life of the sealing bag 6 is effectively prolonged, the sensitivity of the device in the use process is improved, and the safety and the reliability of the device in the use process are improved.

Wherein, the inner cavities of the sealing bag 6 and the triggering mechanism 7 are filled with hydraulic transmission oil with lower viscosity.

In the technical scheme, the triggering mechanism 7 comprises a conversion box 71, a detection cylinder 72 and a triggering core rod 73, the bottom of the inner cavity of the conversion box 71 is communicated with the inside of the sealing bag 6, the top of the inner cavity of the conversion box 71 is communicated with the inside of the detection cylinder 72, the triggering core rod 73 is fixedly and movably sleeved on the left side of the inner cavity of the detection cylinder 72, and one side of the triggering core rod 73 is movably connected with one side of the inner cavity of the detection cylinder 72 through a telescopic spring.

For the arrangement of the trigger mechanism 7, the volume change in the sealed bag 6 is sensed by detecting the position of the hydraulic transmission oil in the detection cylinder 72 through the trigger core rod 73, so that no other substances are mixed in the running process of the safety pedal 4.

In this technical scheme, the top of conversion case 71 inner chamber just floats and is provided with the counter weight clamp plate on hydraulic transmission oil.

Wherein, to the setting of counter weight clamp plate in conversion case 71, the effectual change that has reduced because of ambient temperature's change causes the change of hydraulic drive oil volume, and then leads to the device to report by mistake or the problem that the sensitivity reduces.

In the technical scheme, an induction ring is arranged on the inner wall of the detection cylinder 72 and 3-5 cm away from the left side of the trigger core rod 73.

The induction ring is electrically connected with the emergency braking device, and when the triggering core bar 73 is contacted with the induction ring, the emergency braking device is triggered immediately to stop the operation of the escalator.

The inner diameter of the conversion box 71 is larger than that of the detection cylinder 72, so that the trigger core bar 73 can move enough to trigger the emergency braking device when being triggered, and meanwhile, the situation that the braking device is mistakenly reported can be prevented.

The use method and the working principle of the embodiment are as follows:

when the escalator normally runs, the volume of the sealing bag 6 cannot be changed, so that the positions of hydraulic transmission oil in the inner cavities of the sealing bag 6 and the triggering mechanism 7 cannot be changed, when the escalator is involved in other objects, the objects firstly press the sealing bag 6 under the driving of the lifting ladder 3, so that the volume of the sealing bag 6 is changed, the hydraulic transmission oil in the inner cavity of the sealing bag 6 is further compressed, the hydraulic transmission oil is compressed into the detection cylinder 72 through the conversion box 71, the triggering core rod 73 is driven to move towards the left side to compress the connected telescopic spring, meanwhile, the triggering core rod 73 is in contact with the induction ring on the left side of the inner wall of the detection cylinder 72, so that a feedback signal is sent to an emergency braking control system, an emergency automatic button is immediately started through related maintenance personnel, the running of the escalator is stopped, and the whole emergency braking process can be finished without artificial control, flexible reaction, short braking time and high safety.
