Abstract
The invention discloses a rotary lifting appliance, which comprise a hand crank, a 'three-in-one' reducer and a lifting hook body, wherein the 'three-in-one' reducer adopts an involute cylindrical gear for transmission and has the characteristics of parallel output, compact structure, large transmission torque, stable operation, low noise and long service life; the output of the 'three-in-one' reducer uses a hollow shaft and a hook spline shaft in combination to rotate the hook at a constant speed when a motor is started, and thus functions such as workpiece surface quenching uniformity are ensured; and a power supply mode is three-phase four-wire power supply, and a power supply supplies power to the motor of the rotary lifting appliance through a cable drum placed on a crab of a crane and a three-phase socket. The rotary lifting appliance and the hook of the crane are used in combination, the working characteristic of the rotary lifting appliance is that the rotary lifting appliance is mainly used for rotary quenching of a slender piece of a deep well quenching furnace and doing other work. Compared with the prior art, the rotary lifting appliance has the advantages of strict structure, precision and small dimensions and the like.
Description
One, technical field
The present invention relates to a kind of and the matching used rotary hanger of crane hook.
Two, background technology
Deep-well hardening furnace slender piece quenches, and needs rotational workpieces in quenching process, and existing load hook can't meet requirements, but and workpiece in rotary course, need to satisfy at the uniform velocity rotation and rotating rotation.
Existing rotary hanger reductor adopts common singly-bound or other to cooperate with hook, and both have certain hysteresis when rotation mutually takes place, can not guarantee the equilibrium of quenching.
Three, summary of the invention
The present invention is directed to above weak point, provide that a kind of structure is tight, the smart little rotary hanger of size.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of rotary hanger comprises suspension bracket, and the suspension bracket bottom is provided with hook, and top is provided with the suspension ring supporting with load hook, and described suspension bracket is provided with and hook bonded assembly hook rotating driving device.
Above-mentioned rotary hanger, described supporting suspension ring comprise at least one suspension rod, an end of at least one suspension rod is provided with suspension rod distance adjustment handle.
Above-mentioned rotary hanger, described rotating driving device comprises reductor, reductor adopts the involute cylindrical gear transmission.
Above-mentioned rotary hanger, the speed reducer output shaft of described actuating device are hollow defeated, hollow output shaft and hook spline fitted.
Above-mentioned rotary hanger, described actuating device comprises electrical motor, electrical motor adopts three-phase four-wire power supply formula electrical motor.
Above-mentioned rotary hanger, described suspension rod are two, and two suspension rods be arranged in parallel, and an end of each suspension rod is provided with suspension rod distance adjustment handle.
Beneficial effect of the present invention shows:
1, the present invention adopts and to melt retarder, electrical motor and drg " three-in-one " reductor in one, has characteristics such as parallel output with motor shaft, compact conformation, transfer torque are big, stable working, noise is low, the life-span is long.
2, reductor adopts the involute cylindrical gear transmission, has that parallel output, compact conformation, transfer torque are big, a stable working, noise is low, the life-span is long characteristics.
3, reductor output has adopted hollow shaft and its suspension hook castellated shaft to be used in combination, and makes the suspension hook rotation with balancing speed when motor starts, thereby has guaranteed function such as surface of the work quenching equilibrium.
4, adopt two suspension rod suspension hook forms, lift by crane more safe and reliablely, two suspension rods have made things convenient for putting into and taking out of load hook apart from adjustable simultaneously.
Four, description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the left TV structure scheme drawing of Fig. 1;
Fig. 3 is the plan structure scheme drawing of Fig. 1.
Five, the specific embodiment
The following correlation technique content of not addressing all can adopt or use for reference prior art.
As shown in Figure 1, 2, 3, a kind of rotary hanger comprises suspension bracket 1, and suspension bracket 1 from top to bottom is provided with suspension ring 2, the hook 3 that cooperates with load hook successively, is provided with between suspension ring 2 and the hook 3 and hook bonded assembly hook rotating driving device.
Described suspension ring 2 comprise two suspension rods 21, and an end of each suspension rod 21 is provided with suspension rod distance adjustment handle 22, and the other end of suspension rod 21 distance adjustment handles 22 is attached on the suspension bracket 1, and two regulating handles 22 are respectively equipped with both sides and are symmetrical distribution.
Described actuating device is " three-in-one " reductor, and described reductor adopts the involute cylindrical gear transmission, and reductor output has adopted hollow shaft and the combination of its suspension hook castellated shaft to make.
This rotary hanger power supply mode is a three-phase four-wire power supply, and power supply has and is placed with cable drum on the monkey, and gives the power supply of rotary hanger motor by the form of three-phase socket.Cable is packed up automatically when not working, and has guaranteed the safety of power supply.
During use, rotate two regulating handles 22, make that the distance between two suspension rods 21 becomes big, then load hook 4 is put between two suspension rods, and then rotation regulating handle 22, make suspension rod 21 corresponding with load hook 4.
The load hook 4 of upwards slinging then, load hook 4 are sling rotary hanger, utilize rotary hanger quenched member to be sling then again and get final product.
During quenching, start electrical motor 5, shackle hook body 3 is at the uniform velocity rotated, thereby drive the quenched member uniform rotation to reach the balanced purpose of quenching.
