Abstract

The utility model discloses a novel winding barrel device with a built-in motor for a crane, which is small in volume, high in efficiency and low in energy consumption and is composed of a winding barrel support (1), a needle roller bearing (2), a reducer (3), a motor (4), a connecting bolt set (5) and a winding barrel (6). The winding barrel support is fixed through four connecting bolt sets, a needle roller bearing support is fixed on the winding barrel support through a bolt, and two ends of the winding barrel are arranged inside the needle roller bearing and supported by the needle roller bearing. An internal gear ring is arranged inside an end of the winding barrel, a reducer gear is provided with a hard tooth surface, the reducer is fixed on the winding barrel support through the bolt, the motor with a brake is integrally connected with the reducer through the bolt, and the motor is arranged inside the winding barrel. When the motor is connected with electricity and rotates to drive the reducer, an output gear of the reducer drives the winding barrel supported on the needle roller bearing to rotate. The winding barrel support is made of short-staple glass fiber reinforced composites.

Description

The built-in winding drum device of a kind of hoisting crane New-type electric machine

One, technical field

The utility model relates to the built-in winding drum device of a kind of hoisting crane New-type electric machine.

Two, background technology

At present, there is the problem that efficient is low, energy consumption is big, volume and weight is big in crane hoisting machine system: 200780000795.4 patents are the crane of a kind of low latitude hoisting crane, this crane comprises: crane carriage, the point of load that wherein is passed to truss is positioned on the vertical surface of a side of this truss, and the balance of maintenance offset placed load, thereby the overall weight of mitigation system; And balanced allocation units, these equilibrium allocation units are installed between crane carriage and the guide rail, are used to absorb the impact load that is passed to crane carriage and balancedly distribute whole vertical load.By the first support wheel partial sum, the second support wheel part is set on first vertical surface of described truss, even if when making mobile phase to heavier object, buckling phenomenon can not appear on truss yet.But 200710181196 patents are the crane arm pitching that is attached at mast that crane arm on the swivel and crane arm pitching use with having pitching, is used to drive crane arm with the master of capstan winch and suspention load usefulness to be risen and reuses capstan winch and assisted and reused capstan winch.Led to reuse capstan winch and assisted and reused capstan winch and be installed on the crane arm, the crane arm pitching is installed in the crane arm pitching with on the mast with capstan winch.01815708.4 patent is a kind of device of auxiliary ropes of the hoist gears that is used for arranging hoisting crane, this hoisting crane comprises: trolley (1); Hoist gears (2) with capstan drum (3), this hoist gears (2) are arranged in the trolley (1); Ropes (4), this ropes (4) is arranged in (3) on the capstan drum; Loading part (7), this loading part is suspended on the trolley (1) by ropes (4), and is useful on the sheave (8) of ropes, and ropes can be returned trolley through this sheave (8); Four equipment gears (10), these four equipment gears (10) are arranged in the trolley (1), are used to control loading part () 7 and are contained in swing and the deflection that this loading part (7) is gone up load; Auxiliary ropes (12), this auxiliary ropes (12) are arranged on the rope drum (11) of equipment gear (10); And in loading part (7) and be used for the sheave (13) of auxiliary ropes, from the auxiliary ropes (12) of the oblique process of rope drum (11) of equipment gear (10) by space (14) this sheave (13) guiding capstan drum, that be used for auxiliary ropes (12).

Three, summary of the invention

The purpose of this utility model is exactly to provide the hoisting crane New-type electric machine that a kind of volume is little, efficient is high, energy consumption is low built-in winding drum device, and the winding drum support is fixed by quadruplet tie bolt group, and the needle bearing seat is fixed by bolts on the winding drum support; The winding drum two ends place in the needle bearing, by needle roller bearing support; Inside, winding drum termination has processed internally toothed annulus; Reducer gear is the hard flank of tooth, and retarder, is connected as a single entity with bolt from the electrical motor and the retarder of band brake on the winding drum support with bolt, and electrical motor places in the winding drum; Electrical motor connects the driving retarder, and output gear of speed reducer connects the winding drum that is supported on the needle bearing; The winding drum support is the short fiber glass fibre reinforced composion, have in light weight, intensity is high, characteristic of low energy consumption.The hoisting crane material is the OPTIM900/960/1100QC high tensile steel plate.

The hoisting crane frequency control is made up of the variable-frequency motor in the mechanism, frequency converter, control device and line protection switch, is furnished with AC/DC reactor, brake unit and braking resistor, filter and transmission fastener around frequency converter; According to the difference of hoisting crane mechanism purposes, optical rotary encoder is equipped with in the used variable-frequency motor of lifting mechanism,, improve adjusting speed accuracy and speed of response; Control device adopts PLC to combine with relay, and the frequency conversion speed-adjusting system that PLC controls inputs to PLC with the gear of cam controller, and the control signal of PLC outputs to frequency converter, by changing the power frequency of asynchronous moving motor, to electric machine speed regulation.
