Abstract

The utility model relates to a crane machine comprising a brake which is a direct current disk brake, a speed reducer and a motor. The utility model is characterized in that the brake, the speed reducer and the motor are arranged coaxially on the base of a common hoister; the speed reduction is realized by the transposition of the relative planetary reducer, the motor, an ingot and a rotor; the complete machine is filled with insulating oil after being sealed; a motor casing is replaced by a rope roll; a left bracket is replaced by the speed reducer; a right bracket is replaced by a power supply device. The utility model has the advantages of compact size, light weight, convenient installation, less liability to spoiling, good water-proof and explosion-proof performance, sensitive and reliable brake ability, long service and high efficiency.

Description

The motorized pulleys hoister

One, straight affiliated technical field

The utility model relates to a kind of elevator machinery, particularly the motorized pulleys hoister.

Two, background technology

At present, lifting is extensively adopted wire rope drum hoister tool in producing, and its rope roll is driven by reductor, and reductor is by driven by motor.Its shortcoming is: the three forms one, and volume is big, and quality is heavy, and inconvenience is installed; The brake sticking brake that adopt motor and reductor junction very easily damages, because meeting water, the Friction disk of band-type brake just skids, and to poor to braking ability, in addition malfunctioning.As explosive Flammable atmosphere, just equipment can not use.

Three, summary of the invention

In order to overcome the above-mentioned shortcoming of existing cylinder hoister, the utility model provides a kind of motorized pulleys hoister, and this hoister not only volume is little, and deceleration and stopping performance is very sensitive, and simple installation can explosion-proof, waterproof.

The technical scheme that other technical matters that solves the utility model adopts is: this machine is made up of A, B, C, D four parts.A is the sealed type dc electromagnetic brake; B is relative planetary reduction gear (my patent applied for); C is the drum type brake electrical motor; D is the current colector power supplier.A, B, C, D install on the same support, and same axle mounting.

The beneficial effects of the utility model are: drg A is owing to adopt O-ring disc type dc electromagnetic brake, and good waterproof performance is braked reliable; The relative planetary reduction gear principle that retarder B adopts.Parts are few, and the reliability height operates steadily, C is the drum type brake electrical motor, replace cylinder motor casing as rope roll, change in stator to change place, traditional cast-aluminum rotor changed into the electromagnetism winding after, fill with capacitor oil, help cooling, among the current supply arrangement D, power supply enters armature loop through the brush holder current colector, this device is again the right support abutment of rope roll, and left support abutment promptly is that the shell of retarder is for it.A, B, C, coaxial being installed on the support of D four parts are formed.

Four, below in conjunction with drawings and Examples the utility model is further specified

Accompanying drawing is a structural representation of the present utility model.

In the accompanying drawing:, (1) dc coil, (2) dyanainic friction bar, (3) brake plate sign indicating number, (4) magnetic conductive shell, (5) retarder shell, (6) decide gear ring, (7) planet tooth axle, (8) center am rest, (9) the moving gear ring of output, (10) output planetary tooth, (11) output hollow shaft, (12) left support abutment end cap, (13) input tooth axle, (14) the female silk of locking, (15) oil sealing, (16) rope roll, (17) motor spindle, (18) rotor, (19) motor shaft, (20) motor inner end cap, (21) rope roll right support abutment, (22) brush holder, (23) current colector

Five, the specific embodiment

A among the figure: be the DC-disc type drg, by installing dc coil (1) dyanainic friction bar (2) energising adhesive in the magnetic conductive shell (4), the outage back is released by main spring, and brake plate (3) is killed, the center spline of brake plate (3) is connected with input tooth axle (13), and input tooth axle is carried out braking.Be divided into relative planetary reduction gear, be packed on the retarder shell (5) by deciding toothed ring gear (6), center am rest (8) is gone up 3 of assemblings and is radially equated, the planet tooth axle (7) that is mutually hexagonal angle is at the gear of this end and decide gear ring (6) engagement, the other end installs output planetary tooth (10) and moving gear ring (9) of output and input tooth axle (13) engagement, and the spline of input hollow shaft promptly drives rope roll (16).B: the motor part replaces motor housing by rope roll (16), spindle (17) installs in it and cast aluminium, rotor (18) is packed on the motor shaft (19), and be embedded with the electromagnetism winding, motor shaft (19) is contained on the motor inner end cap (20) by bearing, this inner end cap (20) is packed in again on the rope roll (16), with supporting as rope roll, this supporting is assemblied on the rope roll right support abutment (21) by bearing again, in brush holder (22) motor shaft (19) rear end is housed is that the hollow power supply that makes is through brush holder, (22) current colector (23) enters the rotor winding, and C also is fixed with protective cover as power supplier, makes the waterproof anti-explosion of this part and safety more reliable.

Claims

One, a kind of electronic hoister, comprise the direct current disk brake, relative planetary reduction gear, the drum type brake electrical motor, sealing power supplier four is formed substantially, it is characterized in that: the direct current disk brake, magnetic conductive shell (4) is interior by being fixed with dc coil (1), dyanainic friction bar (2) can only move axially, can not move radially, install on the planetary reduction gear shell (5) relatively and decide gear ring (6), be equipped with three planet tooth axles (7) on the center am rest (8), respectively be fixed with output planetary tooth (10) on this axle, moving gear ring (9) is packed on the output hollow shaft (11), this hollow shaft (11) is connected with rope roll (16) again, be fixed with spindle (17) in this rope roll (16), be fixed with wound rotor (18) on the motor shaft (19), one end is fixed with current colector (23), and the other end is connected with the input gear axle.
