Manual backup in the utility model, structure is simple.When having a power failure, motor cannot work and cannot open the door, and now needs to pull dynamic chain and opens the door.When pulling chain, sprocket rotation drives drive axis, and drive axis drive motor rotates, and driven gear case works, and completes the operation of enabling.In this process, sprocket rotation, skewed slot on it rotates thereupon, force projection to move along the inclined end face of skewed slot, therefore power transmission shaft also moves thereupon, moves axially in process at power transmission shaft, shaft gear on it moves thereupon, engage with generator shaft gear, power will be turned and be passed to motor shaft, and complete opening door operation; After manual operation terminates, power transmission shaft is return under the effect of power transmission shaft spring, and the shaft gear on it and generator shaft gear depart from, and prevents from damaging motor in energising situation.
As preferably, also comprise cut-off switch in described manual backup, the control end of described cut-off switch contacts with the step surface on power transmission shaft outer wall.This structure makes in the moving process of power transmission shaft, the control end of cut-off switch has different location statuss, and when shaft gear engages with generator shaft gear, cut-off switch is opened, make motor be in off-position, prevent the motor of incoming call damage suddenly in manual operation.
As preferably, one end of described power transmission shaft is withstood power transmission shaft spring and is placed in resistance seat, described resistance seat is placed in resistance cover, damping mechanism is provided with between described resistance seat and resistance overlap, this structure makes turning cylinder in rotation process, have certain resistance, therefore after force side (sprocket wheel end) force, resistance can easily order about the projection on power transmission shaft and moves along the inclined end face of skewed slot, is that power transmission shaft moves axially.
As preferably, described shaft gear and generator shaft gear are bevel gear, and therefore power transmission shaft and motor shaft can be arranged to certain angle, such as, vertically arrange.
Compared with prior art, the utility model has following beneficial effect: the utility model structure is simple, effectively can prevent the card of power transmission shaft from pausing and the generation bending phenomenon, increase work efficiency; There is cut-off switch, can prevent the situation damaging motor when manual operation after electrical power from occurring.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged drawing of a-quadrant in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is further described.
See Fig. 1, a kind of industrial portal crane, this industrial portal crane comprises shell 004, is provided with gearbox 001, electric machine assembly 002, stroke assembly 003, tumbler in shell 004.During normal power supply, electric machine assembly 002 works and drives gearbox 001 to work, and passes out torsion, completes the operation of opening the door or closing the door, and in this process, the shaft gear 09 in tumbler is disconnected from each other with generator shaft gear 21; When having a power failure, motor cannot work, and now need manual zip strip 07 to realize opening the door or the operation of closing the door, in manual processes, shaft gear 09 engages with generator shaft gear 21, therefore can manually zip strip 07 operation that realizes enabling or close the door.
Tumbler specifically in the utility model, is shown in Fig. 2, a kind of industrial portal crane manual backup, comprises the sprocket wheel 05 being provided with chain 07, and described sprocket wheel 05 is located in sprocket housing 06, is wherein provided with bearing 03,04; Also be provided with power transmission shaft 10 in described sprocket wheel 05, described power transmission shaft 10 is provided with shaft gear 09; Manual backup also comprises the generator shaft gear 21 coordinated with described shaft gear 09 being located at motor shaft 24 one end, and its one end and generator shaft gear spring 23 offset; Described sprocket wheel 05 is provided with the jack that the one end for power transmission shaft 10 is inserted, described jack outer wall is provided with skewed slot 021, the outer wall of described power transmission shaft 10 is provided with the projection 08 offseted with the end face of described skewed slot 021, and the other end of described power transmission shaft 10 is provided with power transmission shaft spring 11.
