Изобретение относитс к механизмам установок непрерывного транспорта , и, в частности, может быть использовано в качестве стрелочной (встречной) передачи толкающего конвейера .The invention relates to mechanisms for installations of continuous transport, and, in particular, can be used as an arrow (head-on) transmission of the pushing conveyor.

Известны стрелочные передачи конвейера , включающие стрелочный перевод с механизмом фиксации пера стрелки в крайних положени х и соединенный с приводом переключени блок управлени , имеющий входы включение привода и выключение привода и элемент задержки l Known switch gears of the conveyor, including a switch to the mechanism of fixing the pen arrows in the extreme positions and connected to the switching drive control unit, having the inputs of switching on the drive and turning off the drive and the delay element l

В известных стрелочных передачах привод переключени стрелки включен, по крайней мере на все врем прохождени стрелочной передачи подвижным объектом, что приводит к повышенному расходу электроэнергии и к увеличению износа привода. Кроме того/ подвижные объекты конвейеров часто представл ют собой многотележные сцены. Одной из наиболее опасных аварий конвейера, возникающих на стрелочной передаче, вл етс разЕДЛв сцепа, вызванный переключением стрелочной передачи после прохождени одной тележки сцепа и до входа в зону стрелки второй тележки сцепа.ВIn the known switch gears, the switch actuator of the switch is turned on, at least for the entire time of passing the switch gear by the moving object, which leads to increased power consumption and increased wear of the drive. In addition, conveyor moving objects are often multi-body scenes. One of the most dangerous conveyor accidents that occur on a switch gear is razdelv coupling, caused by switching the switch gear after passing through one of the trailer coupling and before entering the area of the arrow of the second trailer coupling.

результате одна тележка сцепа направл етс на одну отход щую от передачи конвейера,а друга - на другую, что приводит к заклиниванию и повреждению механизмов .конвейера.As a result, one hitch carriage is directed to one outgoing from the conveyor transmission, and the other to the other, which leads to jamming and damage to the conveyor mechanisms.

Наиболее характерной причиной такой аварии вл етс заедание Nfexaнизма передачи, которое приводит к тому, что привод не в состо нии про0 , извести ее переключение. При проходе первой тележки сцепа под-воздействием вибрации, возникающих дополнительных усилий механизм освобождаетс от заедани , и после выхода из зоны стрелки первой тележки привод The most typical cause of such an accident is the jamming of Nfexism of transmission, which leads to the fact that the drive is not able to prevent its switching. When the first carriage is coupled by vibration, additional forces arise, the mechanism is relieved from jamming, and after the first carriage leaves the zone of the arrow of the first carriage

S переключает стрелку на другое направление движени .S switches the arrow to a different direction.

Claims

0 The device contains a pen, arrows 1 of the switch gear associated with the actuator 2 for switching the pen arrows to the corresponding direction consisting of electromagnets (Fig. 2) The inputs of the actuator 2 are connected to the outputs of the control unit 3, which switches the actuator on and off The arrow pen is provided with a fixing mechanism 4, holding the pen in extreme positions. Input 5 activates the drive unit 3 connected to the output of the sensor 6 of the movable object, the output of which is also connected to the input of the device 7 delay. connected to input 8, switching off the drive unit 3. Sensor 6 is placed at a distance L from the pen arrow 1, dL L -Vt (V is the maximum speed of the moving object, t is the maximum time required for switching the transmission mechanism. The output signal of element b is delayed relative to to the input signal at the time t. The inputs of the unit 3 for the direction of movement (addressing system, operator, etc.) are input to the inputs 9 of the unit 3. The device operates as follows. When the load approaches the switch gear (before approaching the sensor 6), the inputs 3 block 3 receives commands for selecting the direction of motion. At the command of the sensor b, block 3 turns on drive 2, which switches the pen of arrow 1 to the desired direction. In this case, the pen is fixed by the mechanism 4. At the same time, the sensor 6 sends a signal to the input of the delay element 7, which is triggered after time t. At his command, unit 3 turns on drive 2, since the time t is equal to the maximum time required for switching the arrow pen, by the time element 7 responds, the pen is in a predetermined state and after switching off the drive 2 it is held in this state by the fixing mechanism 4. Thus, in the device, the turn-on time of drive 2 is equal to or slightly longer than the time required for guaranteed switching of the pen arrow 1. During the passage of the moving object of the pen zone of the arrow, the drive is turned off and the arrow is held in a predetermined position by the locking mechanism. This significantly reduces the turn-on time of the switch drive, i.e. power consumption is reduced and its reliability is increased. In addition, the pen drive and arrows are turned off during the passage of the transfer by a moving object, which significantly reduces the possibility of switching the pointer during the passage of the multi-station mobile coupling of its zone, i.e. the reliability of the transmission operation is increased by reducing the likelihood of the chain breaking. Arrow transfer conveyor, which includes a switch with the mechanism for fixing the pen arrows in the extreme positions and connected to the switch. In order to ensure reliable operation and reduce energy consumption, the input off the drive of the control unit is connected to the output of the element after the connection.
