Description

Door body auxiliary stay mechanism

Technical Field

The utility model relates to a rail transit platform door system, in particular to an auxiliary door body supporting mechanism.

Background

In the existing large-opening half-height platform door system, a door body is arranged on a bearing mechanism, and the door body and the bearing mechanism are driven by a motor to move together to open and close the door. The existing technical problems are that: after the door body is closed, due to the fact that the cantilever of the bearing mechanism is too long, the bearing mechanism is prone to plastic deformation under the action of long-time gravity load, and then the door body falls down and collides with the ground sill to be rubbed, and normal use is affected.

Disclosure of Invention

The purpose of the utility model is as follows: the utility model aims to provide an auxiliary door body supporting mechanism for preventing a bearing mechanism from deforming due to the influence of gravity.

The technical scheme is as follows: the door body auxiliary supporting mechanism comprises a sliding support assembly which is used for supporting the door body, is stored along with the opening of the door body and is supported along with the closing of the door body. Among this technical scheme, the sliding support subassembly is accomodate reducible space and is taken up, plays the supporting role to the door body when strutting, can alleviate and bear the weight of the mechanism and receive the influence of gravity, prevent its deformation.

Furthermore, the sliding support component comprises a hinge support, a first cantilever and a second cantilever, wherein the hinge support is fixedly arranged, one end of the first cantilever is hinged to the hinge support, one end of the second cantilever is supported at the bottom of the bearing guide rail, and the other end of the first cantilever can slide on the second cantilever. When the door body is opened and closed, the end part of the first cantilever slides on the second cantilever to store and unfold the sliding support assembly.

Furthermore, the other end of the first cantilever is hinged with a first pulley trolley, and the first pulley trolley is matched with a sliding groove formed in the second cantilever.

Furthermore, the hinge support is provided with a first angle limit for limiting the rotation of the first cantilever.

Furthermore, the door body auxiliary supporting mechanism further comprises a fixed support, and the hinge support is fixed on the fixed support.

Furthermore, the door body auxiliary supporting mechanism further comprises a sliding rail fixed at the bottom of the bearing guide rail, and the end part of the second cantilever can slide on the sliding rail. When the end part of the second cantilever slides on the slide rail, the supporting point changes along with the opening and closing of the door body, and the length of the force arm can be shortened. Meanwhile, under the state of opening the door, the sliding support assembly moves to the end part of the sliding rail and is stored, and the overall appearance of the door channel and the equipment is not influenced.

Furthermore, the end part of the second cantilever is hinged with a second pulley trolley, and the second pulley trolley is in sliding fit with the sliding rail.

Furthermore, the two ends of the sliding rail are respectively provided with a second angle limit and a third angle limit for limiting the rotation of the second cantilever.

The sliding is smoother through the matching of the pulley trolley and the sliding groove or the sliding rail. Through angle limiting, the cantilever can not rotate any more after rotating to a corresponding angle, and only responds to linear motion.

Has the advantages that: compared with the prior art, the utility model has the following advantages: 1. the sliding support assembly capable of being stored and supported supports the door body, so that the bearing mechanism can be prevented from being deformed under the influence of gravity, and the normal use of the platform door is ensured; 2. the sliding rail is arranged, so that the moving stroke of the sliding support assembly is increased, the supporting point is changed along with the opening and closing of the door, and the size of the sliding support assembly is reduced; meanwhile, under the door opening state, the sliding support assembly can be accommodated at the end part of the sliding rail, and the door body moving channel is not influenced.

Detailed Description

The technical solution of the present invention is further described in detail with reference to the accompanying drawings and examples.

As shown in fig. 1 to 5, an auxiliary door supporting mechanism includes a fixed bracket 5 fixed on the ground, a slide rail 4 fixed on the right side of the bottom of a bearing guide rail 6, and a slide support assembly for supporting a door body, accommodating the door body when the door body is opened, and opening the door body when the door body is closed.

Specifically, the slide-brace assembly includes a hinge bracket 1, a first suspension arm 2, and a second suspension arm 3. The hinge support 1 is fixed on the fixed support 5, the lower end of the first cantilever 2 is hinged with the hinge support 1, the upper end of the second cantilever 3 is hinged with a second pulley trolley 33, a T-shaped sliding groove matched with the second pulley trolley 33 is arranged in the sliding rail 4, and the second pulley trolley 33 is in sliding fit with the sliding rail 4. The upper end of the first cantilever 2 is bent rightwards and hinged with a first pulley trolley 31, the lower end of the second cantilever 3 is correspondingly bent leftwards, a chute 32 matched with the first pulley trolley 31 is formed in the second cantilever 3, and the first pulley trolley 31 is in sliding fit with the chute 32.

In addition, the hinge bracket 1 is provided with a first angle limit 11 for limiting the rotation of the first cantilever 2. And a second angle limit 41 and a third angle limit 42 for limiting the rotation of the second cantilever 3 are respectively arranged at two ends of the sliding rail 4.

The operation of the present invention will be described below.

As shown in fig. 6, when the door is in the open position, the sliding support assembly is accommodated in the right end of the sliding rail 4, and the second suspension arm 3 is restricted by the second angle limit 41 and does not rotate any more. When the door is closed, the bearing guide rail 6 moves rightwards together with the door body until the sliding support assembly is positioned at the left end of the slide rail 4, the sliding support assembly starts to unfold after the second cantilever 3 rotates and is limited by the third angle limit 42 and does not rotate any more, the upper end of the first cantilever 2 slides on the second cantilever 3 until the first cantilever 2 is limited by the first angle limit 11 and does not rotate, and the upper end of the first cantilever 2 slides to the lower end of the second cantilever 3 to complete the door closing in-place process. When the door is opened, the sliding support component relatively moves to the right end of the sliding rail 4 in a supporting state, and then the supporting process is reversed to achieve storage, and when the storage is completed, the door is opened right.
