Embodiment 1

[0029] Embodiment 1: as Figure 1-Figure 4 As shown, a friction slider for a high-rise escape device includes a circular arc guide rail block 301 and a sliding friction pair 302. Above, the front end of the arc guide rail block 301 is fixedly connected with a connecting plate 307 , and the middle part of the front side of the connecting plate 307 is fixedly connected with a rotating shaft 308 , and the rotating shaft 308 is connected to the track car 2 through a bearing 309 .

[0030] Preferably, the above-mentioned sliding friction pair 302 includes a U-shaped card slot 303, and an elastic rubber pad 304 is arranged inside the U-shaped card slot 303, and the elastic rubber pad 304 elastically fits tightly on the arc-shaped guide rail 1, and the U-shaped card slot 303 is left and right. Both the right side and the front side are provided with a compression screw 305 , the inner end of the compression screw 305 abuts against the pressure plate 306 , and the pressure plate 306 i...

Embodiment 2

[0044] Embodiment 2: as Figure 1-Figure 4 As shown, a high-rise escape device includes a vertical arc track 1 and a track trolley 2 installed on the outside of the high-rise building wall. The arc track 1 is provided with two sections of semi-circular arcs in each cycle, and the track trolley 2 passes through the friction slider. 3. Closely connected on the arc track 1 and the track trolley 2 slides down when the carrying gravity is greater than the frictional force received, and the height of each semi-circular arc is the height of a floor.

[0045] Preferably, the above-mentioned track trolley 2 includes a slide plate 201, a cushion 202 and a baffle plate 203, two friction sliders 3 are installed on the back side of the slide plate 201, the front bottom is vertically connected to the cushion 202, the front end of the cushion 202 is provided with a baffle plate 203, and the baffle plate 203 and The seat cushion 202 and the skateboard 201 form a U-shaped structure, and the up...

Embodiment 3

[0050] Embodiment 3: a kind of use method of friction slider for high-rise escape device, this method comprises the following steps:

[0051] (1) Install the arc guide rail block and friction pair of the escape device on the arc track in sequence;

[0052] (2) Fasten the friction pair on the arc guide rail block and adjust the friction force;

[0053] (3) When in use, the human body sits on the cushion and leans on the handrail;

[0054] (4) Give an initial force to the escape device through external force or itself to obtain an initial speed;

[0055] (5) Under the action of friction, the human body descends to the ground along the arc track to realize escape.

[0056] The movement process of the escape device at the starting point and the ending point of a semi-circular arc satisfies:

[0057]

[0058] Among them, m is the total mass of the escape device and the person;

[0059] v 1 is the initial velocity;

[0060] h is the height of the semicircle;

[0061] f m ...

Abstract

The invention discloses a friction sliding block for a high-rise escape device. The friction sliding block comprises an arc guide rail block and a sliding friction pair. The sliding friction pair is mounted at the upper end of the arc guide rail block, and is closely attached to an arc-shaped guide rail. The front end of the arc-shaped guide rail block is fixedly connected with a connecting plate,and the middle of the front side of the connecting plate is fixedly connected with a rotary pair. The rotary shaft is connected to a track trolley through a bearing. According to the friction slidingblock, the arc-shaped guide rail and the friction pair are adopted, and bearing and friction slowing down can be achieved conveniently in the falling process. The track trolley can be kept in the vertical direction all the time through the rotary shaft, the palm is prevented from being scratched, and use safety is improved.

Description

technical field [0001] The invention relates to a friction slider for a high-rise escape device, belonging to the technical field of floor escape devices. Background technique [0002] When a fire breaks out in an existing high-rise building, the escape is usually through the fire platform. During this operation, the operator holds the escape rope tightly, which is easy to scratch the palm of the hand, and the risk is very high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a friction slider for a high-rise escape device to solve the above-mentioned problems in the prior art. [0004] The technical solution adopted by the present invention is: a friction slider for a high-rise escape device, including an arc guide rail block and a sliding friction pair, the upper end of the arc guide rail block is equipped with a sliding friction pair, and the sliding friction pair is closely attached to the arc guide rail , t...
