Abstract
The utility model relates to a speed controller for building tower cranes, which is provided with a casing of the controller. The inner part of the casing of the controller is provided with a motor speed changer and a transmission shaft provided with a weight transmitting wheel provided with a drag rope connected with a weight sensor, the weight transmitting wheel is provided with a return spring which is corresponding to the motor speed changer, the transmission shaft is provided with a shifting block of the motor speed changer, and the shifting block can be used for changing a plurality of running speeds of the building tower cranes. The utility model has the advantage of high sensitivity of speed change and is suitable for changing the weight hanging running speed of the building tower cranes.
Description
The utility model relates to the device of building tower machine safe operation, says it is a kind of building tower motor speed controller in detail.
We know that the speed controller of existing building tower machine is made up of sensor and the dynamo-electric source of building tower main supply switch, and when the overspeed of tower machine, the spring in the sensor is pushed the dynamo-electric source of building tower main supply switch, closes general supply, makes the tower machine out of service.This building tower motor speed controller, can only limit building tower machine can not overspeed, can not play the effect of speed governing; Sensitivity is low, and sensor can crush battery isolator control sometimes, causes damage.
The purpose of this utility model provides a kind of can the switching and builds the multiple running velocity of tower machine, highly sensitive building tower motor speed controller.
For achieving the above object, the utility model can adopt following scheme to realize:
Building tower motor speed controller is provided with controller housing, be provided with the motor speed change-over swith in the controller housing, its keystone configuration characteristics are, be provided with transmission shaft in the controller housing, transmission shaft is provided with the weight transfer wheel, and the weight transfer wheel is provided with drag-line, connect weight sensor, the weight transfer wheel is provided with pull back spring, and is corresponding with the motor speed change-over swith, and transmission shaft is provided with motor speed change-over swith shifting block.
The utility model is owing to be provided with transmission shaft in the control device housing, transmission shaft is provided with the weight transfer wheel, the weight transfer wheel is provided with drag-line, connect weight sensor, corresponding with the motor speed change-over swith, transmission shaft is provided with motor speed change-over swith shifting block, can switch the multiple running velocity of building tower machine, speed governing is highly sensitive, is applicable to switch building tower machine lift heavy running velocity.
Description of drawings
Fig. 1 is the A-A cutaway view of Fig. 2, also is front view, and Fig. 2 is the birds-eye view of Fig. 1, and Fig. 3 is the B-B cutaway view of Fig. 2, and Fig. 4 is the C-C cutaway view of Fig. 2.
Below in conjunction with accompanying drawing the utility model is elaborated.
As can be seen from the figure, building tower motor speed controller is provided with controller housing 1, be provided with motor speed change-over swith 6 in the controller housing 1, be provided with transmission shaft 5 in the controller housing 1, transmission shaft 5 is provided with weight transfer wheel 3, and weight transfer wheel 3 is provided with drag-line 7, connect weight sensor, weight transfer wheel 3 is provided with pull back spring 4, and is corresponding with motor speed change-over swith 6, and transmission shaft 5 is provided with motor speed change-over swith shifting block 2.As can be seen from the figure, be provided with four motor speed change-overs swith 6 in the controller housing 1, corresponding with it, transmission shaft 5 is provided with four motor speed change-over swith shifting blocks 2, can adopt four speed motors, can change four kinds of running velocitys; Also can be other change speed motors, corresponding with it, motor speed change-over swith 6 also adopts many motor speed change-overs swith, can switch multiple running velocity.Motor speed change-over swith shifting block 2 can be a cam.Pull back spring 4 can be a disc spring.Controller housing 1 is installed on the tower machine arm, and the drag-line 7 on the weight transfer wheel 3 connects weight sensor.When load was light, weight transfer wheel 3 degreeof turns were little, and motor switches to quick operation; When load was heavier, weight transfer wheel 3 degreeof turns were big, and motor switches to slow running, and pull back spring 4 can drive transmission shaft 5 returns.
