Detailed Description

The invention is further illustrated below with reference to the following examples:

fig. 1 is a schematic structural view of the safety escape lifting device for student dormitories provided by the utility model. Fig. 2 is a schematic view of the pedal of the lifting device for safe escape in students' dormitory.

Referring to fig. 1 and 2, a lifting device for students' dormitory safety escape includes: the chain wheel type speed limiting device comprises a guide rail 1, a bracket 2, a first chain wheel 3, a second chain wheel 4, a third chain wheel 5, a connecting piece 6, a chain 7, a heavy object 8, a speed limiting device 9, a sliding block 10 and a buffering device 11.

The sliding block 10 is fixedly connected with the bracket 2, the sliding block 10 is connected to the guide rail 1 and can slide on the guide rail 1 along the vertical direction, the bracket 2 is positioned on the right side of the guide rail 1, and the buffer device 11 is fixedly arranged at the lower end of the guide rail 1 and is positioned below the bracket 2.

One end of the chain 7 is fixedly connected with a sliding block 10, the chain 7 sequentially rounds the first chain wheel 3, the third chain wheel 5 and the second chain wheel 4, the other end of the chain 7 is connected with the weight 8, and the mass of the weight 8 can be 10kg, but the invention is not limited thereto.

Further, a pedal 15 is disposed above the bracket 2.

Further, the shape of the pedal 15 is rectangular.

The utility model provides a students' dormitory safety elevating gear that flees still includes: the ground 12 of the previous floor and the ground 13 of the current floor, the ground 12 of the previous floor is the ground of the previous floor in the building, and is the ceiling of the current floor, for example, the ground of the fifth floor is the ground of the previous floor of the fourth floor; the upper floor 12 has an opening 14. The shape of the footplate 15 is matched to the shape of the opening 14 so that the footplate 15 can pass through the opening 14, for example, the opening 14 of the upper floor 12 may be rectangular or circular. When the device is installed, one or more openings which are consistent with the shape of the pedal are arranged on the ground of each floor, so that the pedal 15 of the device can pass through the openings when being lifted.

The speed limiter 9 of the safety escape lifting device is used for limiting the rotation speed of the third chain wheel 5, so as to limit the movement speed of the chain to a relatively low speed, for example, the linear speed of the chain is controlled to be 0.5m/s, but is not limited thereto. The speed limiting device 9 can increase the rotating friction force of the third chain wheel 5, which is common in the prior art and is not described in detail. Since the speed of the chain 7 coincides with the speed of movement of the pedals 15, the person's speed is maintained at a safe speed, for example 0.5m/s, when falling, not too fast to be dangerous. In addition, the buffer device 11 can also play a role in buffering the bracket 2 falling to the floor 13, and ensure that people can safely and stably land on the pedal 15.

Need to explain: the device can only be used for transportation between the floor and the previous floor, namely, a person on the ground 12 of the previous floor stably falls to the ground 13 of the floor on the pedal 15, and the gravity of the person is greater than that of the heavy object 8; the weight 8 has a weight greater than that of the bracket 2 and the step 15 but less than that of a general human body, for example, the total mass of the bracket 2 and the step 15 may be 5kg, and the bracket mass may be 10kg, but is not limited thereto. When the device is not in use, no one is standing on the step 15, and since the weight of the weight 8 is greater than the weight of the step 15 and the pallet 2, the chain 7 is pulled by the weight of the weight 8 to the top of the rail 1 with the pallet 2 and the step 15, i.e. when the step 15 is in the opening 14 of the ground 12 of the previous floor and the step 15 is level with the ground 12 of the previous floor.

The using method comprises the following steps: when a dangerous situation occurs, the evacuee who is located on the ground 12 of the previous floor stands on the pedal 15, because the gravity of the human body is greater than that of the weight 8, the person stands on the pedal 15 and slowly moves downwards along the guide rail 1 at a constant speed, after the person falls to the ground of the next floor (namely the ground 13 of the current floor), the evacuee jumps down the pedal 15, and another escape device (the escape device of each floor is independently arranged) leading to the next floor is picked up on the ground 13 of the current floor according to the same method. After the evacuee leaves the step 15, the step 15 and the bracket 2 are returned to the upper floor 12 by the tension of the weight 8 and the chain 7, so that other people can reuse the escape apparatus. It should be noted that the utility model is used for the safe escape, can only carry people downstairs but can not carry people upstairs. When the device is not in use, a warning mark should be provided near the step 15 to inform surrounding people of the step 15.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
