Abstract

The utility model discloses an escalator overload protection system, which comprises an inclined base is connected between floors, wherein a motor and a drive chain are arranged in the inclined base, the drive chain is connected with a class group, horizontal pads are arranged between the upper and the lower ends of the inclined base and the floors, the drive chain and the class group are arranged between the horizontal pads on the upper and the lower ends, and weighing sensors are arranged between the horizontal pads and the floors. Once having excessive overload, the escalator overload protection system can sense in time through the weighing sensors which are arranged on the front and the rear portions of the class group, thereby preventing overweight goods or too much people from stepping on the class group of an escalator, and effectively monitoring the escalator to be safely used.

Description

A kind of staircase overload protecting system

Technical field

The utility model relates to staircase field, particularly a kind of system for staircase overload protection.

Background technology

Staircase is the indispensable transportation means in market, compares car type elevator, and escalator is mainly people, but its operating variable is more complicated, therefore guarantees that staircase safe handling is still very necessary.Once overload, or there is abnormal running in using, just can only go management by site administrator, cause the probability of escalator fault day by day to increase.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of staircase overload protecting system.

The utility model solves the technical scheme that its technical matters adopts:

A kind of staircase overload protecting system; comprise the sloping bottom being connected between floor; described sloping bottom is built-in with motor and driving chain; on described driving chain, be connected with class's group; between described sloping bottom upper and lower end and floor, be provided with level pad; wherein said driving chain and class's group, between the level pad of upper and lower end, are provided with LOAD CELLS between described level pad and floor.

As a preference, on described floor, be provided with the L-type recess that can block level pad, the lower end of described LOAD CELLS is connected to the horizontal surface upper end of L-type recess.

In order to guarantee that the stressed even described LOAD CELLS of LOAD CELLS is distributed in the left and right two ends of level pad in pairs.

The beneficial effects of the utility model are: this fender guard is by being arranged on the LOAD CELLS of class's group front and back; once occur excessively overload; LOAD CELLS can be responded in time, avoids overburden or too much people to set foot on the class's group on staircase, more effectively monitors the safe handling of staircase.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is right elevation of the present utility model;

Fig. 2 is the partial enlarged drawing of a-quadrant in Fig. 1;

Fig. 3 is birds-eye view of the present utility model.

The specific embodiment

With reference to Fig. 1, Fig. 2; a kind of staircase overload protecting system; comprise the sloping bottom 2 being connected between floor 1; described sloping bottom 2 is built-in with motor 3 and driving chain 4; on described driving chain 4, be connected with class's group 5; wherein thereby motor 3 drives driving chain 4 to drive the movement of class's group 5, and passenger only need to stand in class's group 5 and can realize the movement between floor 1.Between described sloping bottom 2 upper and lower ends and floor 1, be provided with level pad 6, wherein said driving chain 4 and class's group 5 are between the level pad 6 of upper and lower end, and passenger first passes through level pad 6 before entering staircase.Between described level pad 6 and floor 1, be provided with LOAD CELLS 7, for staircase is made to overload protection.Wherein on floor 1, be provided with the L-type recess 8 that can block level pad 6, the lower end of described LOAD CELLS 7 is connected to horizontal surface 81 upper ends of L-type recess 8, LOAD CELLS 7 and floor 1, level pad 6 are organically combined, reduce the installation and maintenance difficulty of LOAD CELLS 7.

Described LOAD CELLS 7 is distributed in the left and right two ends of level pad 6 in pairs, conventionally with four, is advisable, and the load-bearing monitor of LOAD CELLS 7 is more evenly distributed rationally, reduces monitoring blind spot.

LOAD CELLS 7 and host computer control electric system UNICOM, can indicate braking escalator, and cut off the electricity supply, and reduced staircase and caused the probability of fault because of overload; Staircase also can arrange microprocessor control acoustic-optic alarm, according to circumstances to send sound and light alarm, prompt passengers or goods suspend and enter, and avoid escalator to occur serious overload, has further reduced escalator and has caused the probability of fault because of overload.

According to above-mentioned principle, the utility model can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the utility model is not limited to the specific embodiment disclosed and described above, to modifications and changes more of the present utility model, also should fall in the protection domain of claim of the present utility model.

Through facts have proved, the utility model is by being arranged on the LOAD CELLS 7 of class's group 5 front and back, and once there is excessively overload, LOAD CELLS 7 can be responded in time, avoid overburden or too much people to set foot on the class's group 5 on staircase, more effectively monitor the safe handling of staircase.
