Problems solved by technology

However, in the case of frequent cut-off of output power and frequent reversing, this type of device can only be realized by frequent start and stop of the motor and frequent forward and reverse switching.
Long-term use is not conducive to the normal operation of the motor

Embodiment Construction

[0040] The present invention will now be further described in detail with reference to the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.

[0041] like figure 1 , figure 2 , image 3As shown, a start-stop mechanism for working forward and fast backward includes: a drive mechanism and a toggle mechanism connected by a fork rod 8,

[0042] The drive mechanism includes a drive gear 3 that can mesh with the first gear 1 and the second gear 2 respectively, the drive gear 3 is slidably arranged on the drive shaft 4, and the first gear 1 and the second gear 2 rotate in opposite directions;

[0043] The toggle mechanism includes a toggle lever 7 that is slidably arranged, and two toggle fork bars 8 are arranged on the toggle lever 7. The two toggle fork bars 8 are respectively located...

Abstract

The present invention relates to a start-stop mechanism of working feed and rapid return. The start-stop mechanism comprises that a drive mechanism can drive a drive gear to rotate forward and backward, a stirring mechanism comprises a stirring bar in sliding arrangement, the stirring bar is provided with two yoke bars, the two yoke bars are disposed at outer sides of two ends of the drive gear, a gear lever is also disposed on the stirring bar, three stop mechanisms of a first stop mechanism, a manual stop mechanism and a second stop mechanism are disposed in turn on a motion trail of the gear lever, two ends of the stirring bar are connected with soft ropes through sleeving rings, one end of each soft rope is wound and connected onto a roll on a driving shaft while the other ends of the two soft ropes are connected with the first stop mechanism and the second stop mechanism respectively, the stirring bar is sleeved by springs, and the soft ropes penetrate through an outer side of the springs. A sleeving block can limit moving postures of the stirring bar, two ends of the springs are fixedly connected onto the sleeving block and the yoke bars, non-excessive left and right shifting of the stirring bar is ensured, and only distance for meshing of the drive gear from a first gear to a second gear is required to be ensured.

Description

technical field [0001] The invention relates to a transmission conversion mechanism, in particular to a start-stop mechanism for working forward and fast backward. Background technique [0002] The transmission transformation mode of modern power mechanism is mostly carried out by the inverter controlling the motor. The inverter controls the speed of the motor and controls the steering of the motor, which makes the speed output of the motor to the transmission mechanism extremely flexible. However, when the ordinary inverter outputs low frequency, the voltage compensation of the motor is insufficient, and the torque boost of the motor is not enough, which leads to the decrease of the output torque of the motor and the unstable load capacity. Therefore, in the case of low-speed operation and high power requirements, it is still necessary to use a reducer. When the power output by the motor is decelerated by the reducer, the torque can be increased. However, when the output ...
