Description
Йзобреч-ение относитс к подъемно транспортному машиностроению и може быть использовано в конвейерах любо типа. Известно устройство дл аварийно выключени привода, включающее приводную звездочку, соединенную посредством предохранительного злеменTd с втулкой, на которой закреплен отключаюпшй злемент у J. Недостатком данного устройства вл етс сложность конструкции. Наиболее близким к предлагаемому по технической сущности и достигаемому результату вл етс устройство дл аварийного.выключени привода, включающее конечный выключатель и установленную на валу втулку, соединенную со звездочкой 2 J. Недостатком данного устройства вл етс многодетальность и сложность конструкции, наличие упора, вьтолненного в виде скобы с загну- тыми концами, пружины, крючков, укрепленных на ступице звездочки. Цель изобретени - упрощение конструкции . Указанна цель достигаетс тем, что втулка установлена на валу с возможностью продольного перемещени и взаимодействи с конечным выключателем , причем втулка соединена со звездочкой посредством резьбового соединени . На чертеже изображено устройство дл аварийного выключени привода. Устройство включает приводную звездочку I, втулку 2, срезной штифт 3, шпонку 4, конечный выключатель 5. Звездочка I установлена на втулке 2, причем сопр гающиес поверхности звездочки и втулки снабжены резьбой 6, т.е. звездочка 1 навинчена на втулку 2. Кроме того, втулка 2 соединена со звездочкой I срезным штифтом 3. Втулка 2 соединена с приводным валом 7 шпонкой 4.Approach relates to overhead transport engineering and can be used in any type of conveyor. A device for emergency shutdown of a drive is known, which includes a drive sprocket connected by means of a safety element Td to a sleeve on which a disconnecting element is attached to J. The disadvantage of this device is the design complexity. The closest to the proposed technical essence and the achieved result is a device for emergency shutdown of the drive, including a limit switch and a sleeve mounted on the shaft connected with an asterisk 2 J. The disadvantage of this device is the large details and complexity of the design, the presence of an emphasis made in the form of brackets with bent ends, springs, hooks fixed on the hub of the sprocket. The purpose of the invention is to simplify the design. This goal is achieved in that the sleeve is mounted on the shaft with the possibility of longitudinal movement and interaction with the limit switch, the sleeve being connected to the sprocket by means of a threaded connection. The drawing shows a device for emergency shutdown of the drive. The device includes a drive sprocket I, sleeve 2, shear pin 3, key 4, limit switch 5. Star I is mounted on sleeve 2, and the matching surfaces of the sprocket and sleeve are threaded 6, i.e. the sprocket 1 is screwed onto the sleeve 2. In addition, the sleeve 2 is connected to the sprocket I by a shear pin 3. The sleeve 2 is connected to the drive shaft 7 by the key 4.
