SU975998A1 - Device for closing the opening for the passage of rope in a building with hoisting machines - Google Patents

Description

The invention relates to the construction of devices for closing openings in the walls of buildings, through which the rope hoists.

A device for openings is known, which includes a blind, which is located on the frame of the opening and with a drive [1].

A disadvantage of the known device is that it cannot be used to close the openings through which the ropes pass.

The closest to the invention by the technical essence and achieved result is a device zakry- ment opening ¹⁵ for passage of the rope winders in a building, comprising a retractable curtain which is divided into two equal parts, and moving along the guide moving mechanism £ 2}.

A disadvantage of the known devices are low performance.

The aim of the invention is to ensure the closing of the opening effort of the rope with a complex trajectory of its movement and the improvement of performance.

This goal is achieved by the fact that in the device closing the opening for the passage of the rope in the building of hoisting machines, including a folding curtain, divided into two equal parts, moving along the rails and the moving mechanism, the moving mechanism is designed as a rigid frame with a movable frame installed on it rope guide, made in the form of a roller cross, while the roller cross is mounted on a moving frame with the ability to rotate and move it in a vertical plane relative to rigid frame, with a rigid frame pivotally connected to the inner surface of the curtain.

FIG. 1 shows the device, a general view; in fig. 2 - the same plan view; in fig. 3 ”section A-A in FIG. one; in fig. And - the movement mechanism.

The device for closing the opening for the passage of rope 1 in the building of lifting machines contains a folding curtain 2, divided into two equal parts, guides 3 curtains and a mechanism for moving the curtain consisting of a rigid frame A, pivotally connected to the internal parts of the curtain, of a movable frame 5 moving on rollers b on a rigid frame A and a guide 7 kana-15 and 1, made in the form of a roller cross, mounted on a slide (frame using pins 8 with the possibility of rotation of the cross in a vertical plane. The roller cross consists of Etara roller 9, in between which passes the rope 1. To seal was not broken at the time of folding and moving apart the curtains, the edges are covered at the expense of its guides.

The device works as follows.

When moving the rope 1 in its

the trajectory 10 (fig. 1) of the latter, the intersection of the cross, while the roller cross through the guide 7, the moving frame 5 and the rigid frame A, transmits the force to the flap curtain 2.

The curtain 2 can be made in the form of vertical pillars 11, resting 35 on the roller supports 12 and moving in the guides 3. Sash 13 curtains 2 are hingedly connected to the uprights 11 and, depending on the direction of effort of the rope, can be folded or moved apart, keeping closed opening 1A of the building constantly. Due to the fact that the rope guide is made in the form

the roller cross, pivotally mounted in the movable frame 5 ”moving along the rigid frame A, ensures the safety of the rope during its operation and the complexity of its movement with the opening 16 closed by the sheets 15.

The use of this invention will improve the performance, ensure reliable regulation of the thermal regime and save energy to maintain this mode.

Claims (1)

Claim The device for closing the opening for the passage of the rope in the building of lifting machines, including a folding curtain, divided into two equal parts, moving along the rails and a movement mechanism, characterized in that, in order to ensure the closure of the opening by the force of the rope with a complex trajectory of its movement and improve performance in it, the movement mechanism is made in the form of a rigid frame with a movable frame mounted on it, equipped with a rope guide made in the form of a roller the wine is mounted on a movable frame with the possibility of rotation and movement in a vertical plane of a relatively rigid frame, with the rigid frame being pivotally connected to the inner surface of the curtain.
