(5A) DEVICE FOR DOOR HEAD SEAL

one

The invention relates to construction, in particular, to devices for compacting the door leaf of various industrial buildings and structures.

A device for sealing the door leaf is known, comprising a seal made in the form of a bracket installed in the lower part of the blade along its entire length and connected to an actuator made in the form of a movable rod fixed on one side of the canvas and rubber bands mounted on the bracket with a gap , some of which are located in the gap between the bracket and the floor, while others are placed in the gap between the bracket and the lower part of the blade 1.

A disadvantage of the known device is the low reliability of the sealing of the lower part of the web and the impossibility of providing the automatic mode of decompaction and compaction of the lower part when opening and closing the gate.

Closest to the proposed invention is a device for sealing the door leaf, comprising a frame, a leaf, and a power seal in the form of a clip with a rubber band installed in the lower part of the leaf along its entire length 2.

A disadvantage of the known construction is the lack of reliability of compaction of the lower blade due to

to significant friction and kinks that occur between rubber bands and the floor during compaction and decompression of the web, the impossibility of providing during opening and closing

IS door curtain. In this design, this mode is carried out manually.

The purpose of the invention is to ensure the reliability of compaction and automation of compaction mode.

Claims (2)

The goal is achieved by the fact that in the device for sealing the door leaf, which includes the frame, the leaf and the drive seal in the form of: brackets With a rubber band installed from the outer side of the bracket in the lower part of the blade along its entire length, it is provided with an inclined guide and rods placed in bushings installed inside the door leaf, and connected by a crossbar carrying a stand, at one end of which a spring-loaded cage is placed, and on the other - a roller in contact with the guide, while seedlings rods associated bracket connected to the rubber strip and with a gap. FIG. 1 shows the gate, a general view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. 1. A device for compacting the door leaf, includes frame 1, sheet 2, installation 1: {oval of support rollers 3 in the upper part of the frame t. In the lower part of the blade 2, a compactor is installed over its entire length, shaped like a bracket i, enclosed within a rubber band 5, the ends of which are fixed. On both sides of the lower part of the blade 2. Side shelves 6 and 7 of the bracket t are directed upwards and fixed by means of slats 8 to the rubber strip 5 in such a way that a gap is formed between the horizontal shelf 9, the lower edge of the rubber strip 5 and the lower edge of the web 2 to ensure compaction and decompression of the leaf 2 of the gate. The horizontal shelf 9 of the bracket is connected to two rods 10 installed in two bushings 11 fixed inside the canvas 2 to its full height, the ends of the rods 10 are connected to the crossbar 12 located above the canvas, and the rack 13 is fixed in the central part of the crossbar 12 the roller 14 and the other end is mounted in a guide sleeve 15 fixed to the web 2 and connected with a compression spring 16. In the upper part of the frame 1 there is a guide fixed, having a horizontal part 17 and an inclined part 18. At the same time, the roller I is set on a slope of the guide part 18 and interacts along the entire length of the guide when moving the web 2. In the upper part of the frame 1 there is a drive for moving the web 2, made in the form of a tension sprocket 19 and an asterisk 20 mounted on the output shaft of the gearbox 21, whose input shaft connected to the electric motor 22. Through sprockets 19 and 20, the endless chain 23, the lower branch of the co-; The second interacts with the 2kt sprockets rigidly connected to the support rollers 3. The device for sealing the gate works as follows. When electrical power is applied to the motor 22, a torque is transmitted from it to the gearbox 21, the output shaft of which, with a star, begins to move the endless chain 23, the lower branch of which, interacting with the sprockets 2k, produces rotation, and the support rollers 3 "are connected blade 2, begin to roll over the upper part of the frame 1, the same time the blade 2 is moved. When the blade moves at the moment of its opening, the roller It begins to interact with the inclined guide part 18, while the stand 13 It begins to move upward in the guide sleeve 15, thereby causing the spring 16 to compress. Simultaneously, the upward movement of the crossbar 12 moves with the rods 10 installed in the sleeves 11, thereby ensuring the lifting of the bracket k, and with it the lower part of the rubber strip 5, to form thus, there is a certain gap between the threshold and the lower edge of the rubber strip 5. Upon further movement of the web 2, the roller 1 interacts with the horizontal part 17 of the guide and until a full opening of the web 2 is maintained a constant gap between the threshold and the lower edge of the rubber strip 5. When the web 1 is closed, the motor 22 rotates in the opposite direction, moving the roller} k occurs first along the horizontal part 17 of the guide and when the roller It moves along the inclined part 18 of the guide, the stand 13 is lowered down along the guide sleeve 15 under the action of or springs 16, thereby providing a downward movement of the crossbar 12 with the rods 10 in the sleeves 11 and lowering the bracket k and the rubber band 5 connected. At the moment of complete closing of the blade 1 (Fig. 1), the lower edge of the rubber band 5 interacts with the threshold and provides a reliable seal. The use of the present invention improves the reliability of the seal of the lower part of the blade and provides an automatic mode of compaction and compaction of the lower part of the leaf when opening and closing the gate leaf. Claims The device for sealing the door leaf, comprising a frame, a leaf and a drive seal in the form of a bracket with a rubber strip installed on the outside of the bracket in the lower part of the blade, all its length is characterized in that; and automation of the compaction mode, it is provided with a guide, inclined at one end, and with rods placed in bushings installed inside the door leaf, and connected by a crossbar, supporting a rack, at one end of which is placed under the spring clip, and on the other, in contact with the guide, while the free ends of the rods are connected by a brace connected to the rubber band and to the gap.
