Abstract
The utility model discloses a kind of electric chain formula hoist cranes, including hoisting motor, output gear, raising gear and raising sprocket wheel, the electric chain formula hoist crane of the utility model installs friction torque limiters on the output shaft of hoisting motor, the limiter is supported to promote the load equal to load rated safety workload 110%, but do not support the load more than load rated safety workload 160%, it can be spent when overload and fall friction torque limiters, hoist crane is avoided to damage, simultaneously, when installation hoist brake avoids motor from stopping, raising gear assembly and sprocket wheel idle running, it causes to load unexpected swing.
Description
Technical field
The utility model is related to technical field of crane equipment, more particularly to a kind of electric chain formula hoist crane.
Background technology
Electric block is a kind of extraordinary lifting equipment, is mounted on overhead traveling crane, on gantry crane, electric block have it is small,
It is easy to operate from heavy and light, it is easy to use the features such as, be used for industrial and mining enterprises, storage, places such as harbour, and Electric Chain Blocks are protected
The light and handy convenient feature of chain block has been stayed, and improved chain block manual operation, promote the deficiencies of speed is slow, has gathered hand
The advantages of drawing cucurbit and electric block is.
Existing hoist crane usually bears excessive load and causes equipment damage when in use, common hoist crane
On be fitted without the device and structure for preventing problems, therefore the spoilage of hoist crane is high, and maintenance cost is larger.
Invention content
In order to overcome drawbacks described above, the utility model to provide a kind of electric chain formula hoist crane, can solve above-mentioned
Hoist crane there are the problem of.
The utility model in order to solve its technical problem used by technical solution be：A kind of electric chain formula lifting calabash
Reed, including hoisting motor, output gear, raising gear and raising sprocket wheel, the output shaft and output gear of the hoisting motor
It is sequentially connected, output gear drives the rotation of raising gear, and raising gear is by the power transmission of hoisting motor to raising sprocket wheel, raising
Sprocket wheel is close to one end of hoisting motor equipped with friction torque according to selected direction positive and negative rotation, the output shaft of the hoisting motor
Limiter, prevents hoist crane from bearing the overload damaged to it, and the hoisting motor output the tip of the axis is equipped with raising system
Dynamic device, hoist brake are mounted on output shaft end by the way that adjusting screw is adjustable, and hoist brake is for preventing unexpected cause
Raising gear and sprocket wheel idle running.
It is equipped at the cooperation of the output shaft and output gear of the hoisting motor as a further improvement of the utility model,
Transmission gear, the transmission gear are using helical offset teeth wheel construction, module 1, number of gear teeth 12, pressure angle
30 °, modification coefficient is -0.1, and for helical angle for 15 degree to left-hand screw, helical offset teeth wheel construction can improve output shaft and output gear
Take turns the validity of the stability and transimission power of transmission.
The utility model has the beneficial effects that：Output of the electric chain formula hoist crane of the utility model in hoisting motor
Friction torque limiters are installed, which supports to promote the load equal to load rated safety workload 110%, but does not prop up on axis
Hold the load more than load rated safety workload 160%, when overload, which can be spent, falls friction torque limiters, and hoist crane is avoided to cause
Damage, meanwhile, when installation hoist brake avoids motor from stopping, raising gear assembly and sprocket wheel idle running cause to load unexpected pendulum
It is dynamic.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the output shaft structural schematic diagram of the utility model hoisting motor；
It is indicated in figure：1- hoisting motors；2- output gears；3- raising gears；4- raising sprocket wheels, 5- output shafts；6- rubs
Torque limiter；7- rises brake；8- adjusting screws；9- transmission gears.
Specific implementation mode
In order to deepen the understanding to the utility model, the utility model is made below in conjunction with embodiment and attached drawing further
It is described in detail, which is only used for explaining the utility model, does not constitute the restriction to scope of protection of the utility model.
Fig. 1 illustrates a kind of a kind of embodiment of electric chain formula hoist crane of the utility model, including hoisting motor
1, output gear 2, raising gear 3 and raising sprocket wheel 4, output shaft 5 and the output gear 2 of the hoisting motor 1 are sequentially connected,
Output gear 2 drives raising gear 3 to rotate, and raising gear 3 is by the power transmission of hoisting motor to raising sprocket wheel 4, raising sprocket wheel 4
According to selected direction positive and negative rotation, the output shaft 5 of the hoisting motor 1 is close to one end of hoisting motor 1 equipped with friction torque
Limiter 6, prevents hoist crane from bearing the overload damaged to it, and the end of the output shaft 5 of the hoisting motor 1 is equipped with
Brake 7 is risen, hoist brake 7 is mounted on 5 end of output shaft by the way that adjusting screw 8 is adjustable, and hoist brake 7 is for preventing
Raising gear and sprocket wheel is surprisingly caused to dally, which supports to promote the load equal to load rated safety workload 110%, but
Do not support the load more than load rated safety workload 160%, when overload, which can be spent, falls friction torque limiters, avoids hoist crane
It damages, meanwhile, when installation hoist brake avoids motor from stopping, raising gear assembly and sprocket wheel idle running cause load to anticipate
Outer swing.
It is equipped with transmission gear 9 at the output shaft 5 of the hoisting motor 1 as shown in Figure 2 and the cooperation of output gear 2, it is described
Transmission gear 9 uses helical offset teeth wheel construction, and module 1, number of gear teeth 12, pressure angle is 30 °, modification coefficient
It is -0.1, for helical angle for 15 degree to left-hand screw, helical offset teeth wheel construction can improve the stabilization of output shaft and output gear transmission
The validity of property and transimission power.
