Description
Technical Field
The utility model relates to a two mechanisms that drive of time sharing control can be used to the lift control in the vertical lift and use, also can be used to other similar occasions.
Background
In modern logistics conveying systems, lifting devices are widely used. When the traditional lifting equipment uses one of the double power sources as a standby power source, the two power sources are completely separated, and when one of the two power sources fails, the other power source needs to be manually switched. This takes a relatively long time and requires the equipment to be stopped during the changeover, which is not allowed or should be avoided as much as possible for logistics transportation systems with high demand for cycle time.
SUMMERY OF THE UTILITY MODEL
In order to solve the influence beat problem that above-mentioned manual switching leads to, the utility model provides a timesharing control that can switch over fast drives mechanism doubly.
The utility model provides an its technical problem adopted technical scheme be:
a time-sharing control double-drive mechanism mainly comprises a power source, a reduction gearbox, a bidirectional overrunning clutch, a support bearing, a driving gear, a driven gear shaft, a bidirectional backstop, a turbine worm transmission pair, a belt wheel, a turbine transmission shaft and a hand wheel; power sources are respectively arranged on the two outer walls on the left side of the reduction box; a hand wheel is arranged on the left end face of the reduction box; belt wheels are respectively arranged on the two outer walls on the right side of the reduction box; one power source output end is connected with a bidirectional overrunning clutch in the reduction gearbox; the bidirectional overrunning clutch is connected with the driving gear through a supporting bearing; the driving gear transmits driving force to the driven gear shaft through the driven gear; one end of the driven gear shaft penetrates through the reduction box and is connected with the hand wheel; the other end of the driven gear shaft is connected with a bidirectional backstop in series and then is connected with a turbine transmission shaft through a turbine worm transmission pair; two ends of the turbine transmission shaft are connected with belt wheels.
The utility model has the advantages that:
1. the utility model discloses promote the goods in-process at control lift, can only a power supply work, also can two power supplies simultaneous workings.
2. The utility model discloses two power supplies can not the during operation simultaneously, can be with hand wheel connection to reducing gear box on, go up and down goods to needs position through the hand wheel.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings 1 and the reference numerals.
In the process of controlling the lifter to lift goods, only one power source 1 can work, and two power sources 1 can work simultaneously. When only one power source works, the power source is started, the follow-up gears are driven to rotate through the bidirectional overrunning clutch 3, power is transmitted to the belt wheel (chain wheel and the like) 10, and the belt wheel (chain wheel) drives the power transmission medium belt (chain and the like) to lift cargoes. The power source 1 stops rotating and the goods stop at the corresponding position. If one power source 1 fails and cannot provide power, the two-way backstop 8 can ensure that goods stop at the original position without slipping. At this time, the other power source 1 can be started quickly to continue the cargo lifting operation, and the bidirectional overrunning clutch 3 is used as a bearing.
When the two power sources 1 work simultaneously, if the two power sources 1 are asynchronous, the bidirectional overrunning clutch 3 can play a role, and at the moment, the bidirectional overrunning clutch 3 is used as a bearing, so that the power source 1 which is started later or has a slower speed does not participate in the work. And if the power source 1 which is started earlier or has higher speed fails to work, the other power source 1 can take over the driving work instantly.
When the two power sources 1 cannot work at the same time, the goods are stopped in the original position and are not moved. If the goods need to be lifted, the hand wheel 12 can be connected to the reduction gearbox 2, and the goods can be lifted to the required position through the hand wheel 12.
The time-sharing control double-drive mechanism is not only limited to the use of the lifting equipment, but also can be applied to other occasions needing to rapidly switch power sources.
When the device is installed, all parts in the reduction gearbox are installed, and then a power source (a motor and the like) and a belt wheel (a chain wheel and the like) are installed.
The bidirectional overrunning clutch is used for ensuring that a fault power source is separated from the mechanism and cannot become an extra load. The two-way backstop type is used for ensuring that the goods can not slide down under the action of gravity. The hand wheel can be used as emergency power when the power source cannot work. The hand wheel is designed into a special interface, the structure can be disassembled at any time, and the hand wheel is connected with the reduction box body when the function of the hand wheel needs to be rotated.
