The external mounting jib lubbing mechanism comprises a coiling block arranged between vertical plates on the left side and the right side of a rack, wherein a motor is arranged on the vertical plate on one side of the rack and coaxial with the coiling block; the motor drives the coiling block through a reducer which is arranged on the vertical plate on the other side of the rack; an input shaft of the reducer is coaxially and fixedly connected with the interior of an input shaft sleeve; the input shaft sleeve is sleeved with a coiling block connecting sleeve coaxially; the input shaft is connected with the coiling block connecting sleeve through a gear transmission pair with a speed reduction transmission ratio; the input shaft is coaxial and connected with a rotating shaft of the motor through a transmission shaft inside the coiling block; the coiling block connecting sleeve is connected with a corresponding end face of the coiling block. According to the external mounting jib lubbing mechanism, the reducer adopts an external mounting type and is placed outside the mechanism. Therefore, the whole reducer can be seen; the maintenance, adjustment and assembling are convenient; the troubleshooting time is shortened; the maintenance time and period are reduced.
Description
(1) technical field:
The present invention relates to hoisting crane or tower crane inner structure, particularly a kind of external hanging type luffing mechanism.
(2) background technology:
The operating range of hoisting crane or tower crane has several modes, and a kind of is the elevation angle by crane arm, and a kind of is that this structure then is to realize by luffing mechanism by control amplitude variation trolley luffing scope.
Existing luffing mechanism mostly is built-in luffing mechanism, namely is that planetary reduction gear is positioned over reel inside, and the rotating speed of motor is passed to reel through behind the planetary reduction gear, and reel is exported with design speed, thereby reaches the desired luffing linear velocity of luffing mechanism.
Because planetary reduction gear is built in the reel, break down and can not in time find, exist and use hidden danger; And the planetary reduction gear complex structure, the processing and manufacturing difficulty, cost is high.
Need to remove a large amount of parts after built-in luffing mechanism breaks down and investigate, the on site maintenance difficulty, maintenance cycle is long.
(3) summary of the invention:
For the weak point of the built-in luffing mechanism of tradition, the purpose of this invention is to provide a kind of external hanging type luffing mechanism of on-the-spot quick diagnosis maintenance.
Can realize the external hanging type luffing mechanism of above-mentioned purpose, comprise the reel of being located in the frame arranged on left and right sides riser, motor is located on the side frame riser and is coaxial with reel, described motor drives reel by retarder, unlike the prior art be that described retarder is located on the opposite side frame riser, the input shaft of described retarder is coaxial being connected in the input axle sleeve, described input shaft is placed in coaxial package in the reel adapter sleeve, is connected by the gear driving pair with reduction of speed transmitting ratio between described input shaft and the reel adapter sleeve; Described input shaft transmission shaft coaxial with the rotating shaft of motor and by reel inside is connected, and described reel adapter sleeve connects with the corresponding end face of reel.
The present invention partly is positioned over the reel outside to retarder, the rotation of motor is delivered to the transmission gear of retarder by input shaft, reel adapter sleeve by retarder passes to reel to motion again, and reel is exported with design speed, thereby reaches the desired luffing linear velocity of luffing mechanism.
Described gear driving pair comprises one-level miniature gears and the intermediate drive gear system of being connected grade big gear wheel and connecting one-level miniature gears and three grades of big gear wheels, and described one-level miniature gears is connected with input shaft is coaxial, and described three grades of big gear wheels are connected with the reel adapter sleeve is coaxial.
One side riser is provided with the limiting device of control reel rotation amplitude, described limiting device is connected reel by the spacing miniature gears that is meshed with reel terminal pad gear, described spacing miniature gears is connected with the limiting device rotating shaft is coaxial, the coaxial connection of corresponding end face of described reel terminal pad gear and reel.
Advantage of the present invention:
1, the retarder of external hanging type luffing mechanism of the present invention adopts external hanging type and places outside the reel, so whole retarder is visible part, maintenance, adjustment and assembling are all very convenient.
2, investigation is very easy to after the present invention is broken down, and only needs to remove the large lid of retarder, and internal mechanism just covers all at one glance, and has reduced trouble shooting time, has reduced maintenance time and cycle.
3, the present invention can directly change or add lubricating oil, and is convenient, fast, the oil impregnate problem of easier processing retarder.
