Description

The invention relates to the construction, in particular to a sliding gate of industrial buildings and structures.

The purpose of the invention is to increase the reliability of operation of the gate.

FIG. 1 shows the gate, a general view; in fig. 2 - section aa in fig. ' 1, in FIG. 3 — node G in FIG. one; in fig. 4 is a section BB of 10 in FIG. 3

Sliding gates include a frame made from bolt 1, two extreme posts 2 and 3 and one middle pillar 4, door leaf 5 installed 15 in the upper part on the rollers of the suspension 6 on the upper guide 7 attached to the bolt 1. In the lower part of the blade 5 on one side, using a bracket 8, a flange-roller 9 is installed, which interacts with a guide 10 attached to the floor 11 and installed in the doorway between the pillars 2 and 4. On the other side of the blade 5, the bracket 12 is attached to the console 25, L-shaped at the end e which has a flange roller 14 on the vertical axis 13. Above the ground at a height a equal to 30 0.05-0.1 of the height of the opening, an additional guide 15 is installed, made in the form of a channel with shelves directed downwards, the ends of which are fixed inside between the middle stand-35 coy 4 and extreme stand 3. In this case, the flange roller 14 is located inside the channel with a gap and interacts with its side shelves. On the bolt 1, on one side of it, the actuator 16 is installed with an asterisk 17, and on the other side of the bolt 1 it is installed

block 18. Through block 18 and the drive sprocket 17, an endless roller chain 19 is stretched, one of the branches of which is connected to one of the suspension rollers 6. The minimum height of the installation of the guide 15 above the ground is equal to 0.05 of height. maintenance of this area between racks 4 and 3 for the free movement of the blade 5 when the opening for the passage of vehicles is cleared (i.e., clearing this area of icing, snow and other foreign objects that impede the free movement (of the canvas),

The maximum height and the installation of the guide 15 above the ground, equal to 0.1 of the height of the opening, is determined based on the value of the minimum tilting moment acting on the canvas from the effects of wind load on it.

The gate works as follows.

When the drive 16 is turned on, the endless roller chain 19 is moved and the blade 5 moves on the rollers of the suspension 6 along the guide 7. When the wind load is applied to the wind load 5, the flange roller 9 interacts with the guide 10 attached to the floor 11 and the edge roller 14 interacts with the inner side walls of the guide 15, which allows for reliable opening - closed -. canvas across the entire width of its movement.

The use of the proposed gate allows you to increase the reliability of operation of the gate.
