Abstract
The utility model relates to the field of rubbish bridge grabbing cranes, in particular to a rubbish bridge grabbing crane. According to the technical scheme, the rubbish bridge grabbing crane comprises an electric hoist which uses a permanent-magnet synchronous motor, wherein the permanent-magnet synchronous motor is directly connected with winding drums, and two sides of each winding drum are provided with pliers-type brakes. The structure principle of the permanent-magnet synchronous motor is adopted, the permanent-magnet synchronous motor is directly connected with a hoisting device, so that the hoisting function is achieved, the mode that a traditional three-phase alternating-current motor drives a gearbox is replaced, the structure is simpler, the weight is low, transmission is stable, noise does not exist, meanwhile, a variable-frequency speed controller is adopted for control, a PLC or a PC is adopted as an aid, automatic control is conveniently achieved, and the rubbish bridge grabbing crane is more energy-saving and environment-friendly.
Description
Technical field
The utility model relates to garbage grab bucket crane in bridge type field, is specifically related to a kind of operation, jack up unit of garbage grab bucket crane in bridge type.
Background technology
Garbage grab bucket crane is the nucleus equipment of burning city domestic garbage factory rubbish Feed system, is positioned at the top in rubbish storing hole, and that mainly bears rubbish feeds intake, carries, stirs, gets thing and weighing work.Present garbage grab bucket crane adopts crane in bridge type more, and these hoisting cranes adopt electric block as the lifting mechanism of hoisting crane more, and its principle of work is to adopt three phase asynchronous motor to connect change speed gear box to drive reel, realize lifting functions.Just connect change speed gear box by the low torque motor of high rotating speed, realize the low rotation speed large torque that hoists by certain speed ratio, thereby and act on reel and realize lifting functions.There is complex structure in this hoisting crane, and volume is big, and noise is big, the shortcoming of the low and intelligent difference of driving efficiency.
Summary of the invention
The purpose of this utility model provides a kind of garbage grab bucket crane in bridge type, has simple in structure, in light weight, stable drive, efficient is high and easily be automated and intelligentized advantage.
For achieving the above object, the utility model by the following technical solutions, a kind of garbage grab bucket crane in bridge type, comprise electric block, described electric block adopts permasyn morot, and permasyn motor direct connects with reel and links to each other, and the both sides of reel arrange caliper brake; The brake disc assembling of the caliper brake of described permanent-magnet synchronous motor rotor and reel one end and this end is connected, and the brake clamp of permasyn morot stator and caliper brake is fixed on the housing; The brake disc of the reel other end and caliper brake, roll support axle are connected, and the roll support axle is connected by antifriction-bearing box and housing, and the brake clamp of caliper brake is fixed on the housing of electric block.
The electrical control of described electric block adopts variable-frequency governor to be equipped with PLC or PC control again.
By above technical scheme, this garbage grab bucket crane adopts the structural principle of permasyn morot, permasyn motor direct is connect with jack up unit link to each other, and realizes its lifting functions, replaced the mode that traditional three-phase alternating current motor drives change speed gear box, not only structure is simpler, and in light weight, stable drive, noiseless, adopt variable-frequency governor being equipped with the control of PLC or PC simultaneously, convenient realization automation control, energy-conserving and environment-protective more.
Description of drawings
Fig. 1 is the structural representation of jack up unit of the present utility model.
The specific embodiment
A kind of garbage grab bucket crane in bridge type comprises electric block, and described electric block adopts permasyn morot, and permasyn motor direct connects with reel 4 and links to each other, and the both sides of reel 4 arrange caliper brake.This garbage grab bucket crane is used for the driving that electric block hoists with the magnetic-synchro electrical motor, thoroughly changed the type of drive that traditional three-phase alternating current motor drives change speed gear box and then drives reel, overcome gear-driven various disadvantage, not only structure is simpler, and it is in light weight, stable drive, noiseless.Caliper brake makes hoisting of this garbage grab bucket crane brake more steadily and safety.Following mask body is introduced the annexation of permasyn morot and reel:
As shown in Figure 1, the rotor 3 of described permasyn morot is connected with 7 assemblings of the brake disc of the caliper brake of reel 4 one ends and this end, and the stator 10 of permasyn morot is fixed on the housing 1 with the brake clamp 2 of caliper brake; Brake disc 7, the roll support axle 5 of reel 4 other ends and caliper brake are connected, and roll support axle 5 is connected by the housing 1 of antifriction-bearing box 6 with electric block, and the brake clamp 2 of caliper brake is fixed on the housing 1.The housing 1 of electric block is fixed on the bottom of operation wheel 8, and operation wheel 8 is driven by operation motor 9 and rotates, thereby realizes the translation of whole jack up unit.
The electrical control of described electric block adopts variable-frequency governor to be equipped with PLC or PC control again.So not only convenient realization automation control, and energy-conserving and environment-protective more, service life is higher.
Claims (2)
1. a garbage grab bucket crane in bridge type comprises electric block, it is characterized in that: described electric block adopts permasyn morot, and permasyn motor direct connects with reel and links to each other, and the both sides of reel arrange caliper brake; The brake disc assembling of the caliper brake of permanent-magnet synchronous motor rotor and reel one end and this end is connected, and the brake clamp of permasyn morot stator and caliper brake is fixed on the housing; The brake disc of the reel other end and caliper brake, roll support axle are connected, and the roll support axle is connected by the housing of antifriction-bearing box and electric block, and the brake clamp of caliper brake is fixed on the housing.
