Description
Technical Field
The utility model relates to the technical field of rail transit shielding doors, in particular to a pulley guide rail of a half-height safety sliding door.
Background
The half-height safety sliding door is used for surrounding the space between a subway platform and a train on the platform in a glass curtain wall mode. When the train arrives, the half-height safety sliding door is opened again for passengers to get on or off the train; the sliding structure of the half-height safety sliding door in the prior art adopts a linear guide rail, so that the cost is higher and the bearing load is small.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a reasonably designed pulley guide rail of a half-height safety sliding door, a balance wheel and a supporting wheel in the device form an integrated structure through a pulley bracket structure, and a gap between the pulley guide rail is adjusted through an eccentric shaft sleeve.
In order to achieve the purpose, the utility model adopts the following technical scheme: it comprises the following steps:
the two support wheels are arranged on the left side and the right side of the bracket in a rolling manner through the fixed shaft and the bearing respectively;
the two horizontal balance wheels are respectively arranged on the bracket at one side of the supporting wheel through a fixed shaft and a bearing in a rolling manner;
the horizontal adjusting wheel is arranged on one side of the supporting wheel on the left side;
the supporting adjusting wheel is arranged on one side of the supporting wheel on the right side; the middle parts of the supporting adjusting wheel and the horizontal adjusting wheel are fixedly provided with adjusting shafts in a penetrating mode, the outer side of each adjusting shaft is sleeved with an eccentric shaft sleeve, and the eccentric shaft sleeves are rotatably arranged on the support through bearings.
Compared with the prior art, the utility model has the beneficial effects that: according to the pulley guide rail of the semi-high safety sliding door, the balance wheel and the supporting wheel in the device form an integrated structure through the pulley support structure, and the gap between the pulley rails is adjusted through the eccentric shaft sleeve.
Description of the drawings:
fig. 1 is a schematic structural view of the present invention.
Fig. 2 is a top view of fig. 1.
Fig. 3 is a left side view of fig. 1.
Description of reference numerals:
the device comprises a supporting wheel 1, a fixed shaft 2, a horizontal balance wheel 3, a horizontal adjusting wheel 4, a supporting adjusting wheel 5, an adjusting shaft 6, an eccentric shaft sleeve 7 and a bracket 8.
The specific implementation mode is as follows:
the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to fig. 3, the following technical solutions are adopted in the present embodiment: it comprises the following steps:
the two supporting wheels 1 are respectively arranged on the left side and the right side of the bracket 8 through the fixed shaft 2 and the bearings in a rolling manner, so that the rolling smoothness of the supporting wheels 1 is ensured;
the two horizontal balance wheels 3 are respectively arranged on the bracket 8 at one side of the supporting wheel 1 through the fixed shaft 2 and the bearing in a rolling manner, so that the rolling smoothness of the horizontal balance wheels 3 is ensured;
a horizontal adjustment wheel 4, which is a main structural member ensuring stability in the horizontal direction, is provided on one side of the support wheel 1 on the left side;
a support adjusting wheel 5, which is a main structural member ensuring stability in the vertical direction, is provided on one side of the support wheel 1 on the right side; the middle parts of the supporting adjusting wheel 5 and the horizontal adjusting wheel 4 are fixedly provided with an adjusting shaft 6 in a penetrating mode, the outer side of the adjusting shaft 6 is sleeved with an eccentric shaft sleeve 7, and the eccentric shaft sleeve 7 is rotatably arranged on a support 8 through a bearing.
The working principle of the specific embodiment is as follows: the guide rail drives the guide rail to keep stable movement in the vertical direction through the rolling of the supporting wheel 1; the guide rail drives the guide rail to keep stable movement in the horizontal direction through the rolling of the horizontal balance wheel 3; the horizontal balance wheel 3 is driven to rotate by rotating the fixed shaft 2, and the angle of the horizontal adjusting wheel 4 is adjusted by the eccentric shaft sleeve 7, so that the distance between the surface of the horizontal adjusting wheel 4 and the surface of the supporting wheel 1 is changed, the gap between the horizontal adjusting wheel 4 and the guide rail groove is adjusted, and the guide rail is ensured to horizontally and stably move; the supporting adjusting wheel 5 is driven to rotate by rotating the adjusting shaft 6, and the angle of the eccentric shaft sleeve 7 is adjusted, so that the distance between the wheel surface of the supporting adjusting wheel 5 and the wheel surface of the supporting wheel 1 is changed, the gap between the supporting adjusting wheel 5 and the guide rail groove is adjusted, and the guide rail can stably move in the vertical direction.
After adopting above-mentioned structure, this embodiment's beneficial effect is as follows:
1. the support 8 is an integrated structure, and the horizontal balance wheel 3, the support wheel 1, the support adjusting wheel 5 and the horizontal adjusting wheel 4 in the device form an integrated structure through the structure of the support 8;
2. the gap between the wheel rails is adjusted through the eccentric shaft sleeve 7, and therefore the guide rails are guaranteed to run stably in the horizontal direction and the vertical direction.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the utility model can be made, and equivalents and modifications of some features of the utility model can be made without departing from the spirit and scope of the utility model.
