Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1, 2 and 3, the platform type elevator car bottom anti-pinch structure comprises a car bottom main body 1, wherein a bottom end plate 2 and an anti-pinch end plate 3 are sequentially arranged on the side wall, close to a well wall, of the car bottom main body 1 from bottom to top, the anti-pinch end plate 3 is hinged with the car bottom main body 1 through a hinge 18, the bottom end plate 2 is fixedly connected with the car bottom main body 1, and a first spring 4 is fixed between the anti-pinch end plate 3 and the bottom end plate 2; when foreign matters are clamped between the car bottom edge and the shaft wall, the anti-clamping end plate 3 correspondingly rotates, so that the clamped foreign matters have a moving space, the shaft wall is prevented from being damaged, and the internal structure of the elevator is protected; a sensing device is further arranged between the anti-pinch end plate 3 and the bottom end plate 2, the sensing device comprises an angle sensor 8 fixed on the bottom end plate 2, the angle sensor 8 is in communication connection with an elevator host, the input end of the angle sensor 8 is connected with a rotating rod 9, and the other end of the rotating rod 9 is close to the bottom of the anti-pinch end plate 3; the length direction of going up edge on dwang 9 is equipped with slide rail 10, is equipped with gliding slider 11 on the slide rail 10, and it has connecting rod 6 to articulate on slider 11, and the connecting rod 6 other end articulates on bottom end plate 2, still is fixed with second spring 7 between connecting rod 6 and bottom end plate 2. In this embodiment, the bottom end plate 2 is further provided with a hinged support 5, the connecting rod 6 is hinged to the bottom end plate 2 through the hinged support 5, and an included angle between the connecting rod 6 and the rotating rod 9 is an obtuse angle. The hinge support 5 is prior art and the detailed structure thereof will not be described herein. Because the connecting rod 6 articulates on slider 11, so under the effect of second spring 7 elasticity, the connecting rod 6 can promote slider 11 to sliding to the one end that is close to anti-pinch end plate 3 on slide rail 10, until sliding to the end of slide rail 10, and under the combined action of slider 11 and slide rail 10 this moment, the one end of dwang 9 and anti-pinch end plate 3 below contact. The slide rail 10 and the slide block 11 are both in the prior art and are mainly used in the linear reciprocating motion situation, and the detailed structure thereof is not described herein. When the foreign matter is gone into to the card between edge and well wall at the bottom of the sedan-chair, prevent that clamping end plate 3 receives pressure to take place to rotate, then press and move dwang 9 and rotate, dwang 9 drives angle sensor 8's input and rotates, then angle sensor 8 gives the elevator host computer with the signal transmission, control elevator host computer stop operation. The angle sensor 8 and the communication connection method between the angle sensor 8 and the elevator main machine are both the prior art, and the embodiment does not improve the prior art, and the specific mechanism and principle of the prior art are not described herein again. After the foreign matter in the gap is taken out, the anti-pinch end plate 3 resets, and the rotating rod 9 resets under the combined action of the second spring 7, the connecting rod 6, the sliding rail 10 and the sliding block 11.

As shown in fig. 1 and 4, a slidable limiting sleeve ring 12 is sleeved on the rotating rod 9, a jackscrew 13 in threaded connection with the limiting sleeve ring 12 penetrates through the limiting sleeve ring 12, one end of the jackscrew 13 extends into the limiting sleeve ring 12, and when one end of the jackscrew 13 extending into the limiting sleeve ring 12 abuts against the surface of the rotating rod 9, the side wall of the limiting sleeve ring 12 limits the sliding block 11 to slide. The limit collar 12 and the slider 11 in this embodiment are in contact with each other at the end far from the angle sensor 8, and the limit collar 12 can be fixed on the rotating rod 9 after the jackscrew 13 is screwed down. The angle that dwang 9 can rotate is controlled through the sliding distance of restriction slider 11 to spacing lantern ring 12, further restricts dwang 9 and keeps away from 8 one end utensil of angle sensor and prevents pressing from both sides the distance of end plate 3 to can realize preventing the effect that the mistake touched. When 8 one end utensil of angle sensor was kept away from to dwang 9 prevents pressing from both sides end plate 3 and has the distance, prevent pressing from both sides end plate 3 and take place the rotation that little rotation can not lead to dwang 9, avoid the elevator host computer to shut down.

As shown in figures 1 and 4, the side wall of the position-limiting lantern ring 12 is provided with an opening and is in a C-shaped structure, and the jackscrew 13 is arranged at the top of the C-shaped structure of the position-limiting lantern ring 12. The limiting sleeve ring 12 is made of low-carbon steel and has good plasticity, the gap part of the limiting sleeve ring 12 can be enlarged during installation, and the limiting sleeve ring 12 is closed by pressing the upper end and the lower end of the limiting sleeve ring 12 after installation.

As shown in fig. 1, a roller 14 abutting against the surface of the anti-pinch end plate 3 is disposed at one end of the rotating rod 9 close to the anti-pinch end plate 3. The roller 14 can reduce the friction between the rotating rod 9 and the anti-pinch end plate 3.

As shown in fig. 1 and 2, a flexible plate 15 is provided at the edge of the anti-pinch end plate 3. The flexible plate 15 adopts the silica gel material, and the flexible plate 15 makes the edge of preventing pressing from both sides end plate 3 more soft, when child's foot card goes into the gap, can play better guard action to child's foot.

As shown in fig. 2, a brush strip 16 is provided at the edge of the flexible sheet 15. The brush strip 16 extends out of the flexible plate 15 and can be in direct contact with the wall of the well, so that sundries with small volume can be prevented from entering gaps.

As shown in fig. 2, the anti-pinch end plate 3 is hinged to the top of the upper side wall of the platform main body 1 and is flush with the top surface of the platform main body 1; the bottom end plate 2 is fixed at the bottom of the upper side wall of the car bottom main body 1 and is parallel to the anti-pinch end plate 3, and the size of the bottom end plate 2 is the same as that of the anti-pinch end plate 3; the top surface edge of sedan-chair bottom main part 1 is equipped with dustproof apron 17, and dustproof apron 17 covers in the articulated gap department of preventing pressing from both sides end plate 3. The dustproof cover plate 17 can reduce dust entering a gap between the anti-pinch end plate 3 and the car bottom main body 1 in a hinged mode.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
