Specific implementation mode

A kind of turn device, including the bar 10 that rises, the leading portion being inserted in stator A cavitys on the bar 10 that rises have rising for radial displacement Tight stick 11, described rising are provided with guide and limit mechanism between bar 10 and lifting unit, the bar 10 that rises is along guide and limit The 10 bar core of bar that rises when mechanism displacement is respectively at vertical direction or horizontal direction position.

In said program, the leading portion for the bar 10 that rises is inserted in stator A cavitys simultaneously fixed stator A, at this point, the centers stator A Line is overlapped with the 10 bar core of bar that rises, and the 10 bar core of bar that rises when the bar 10 that rises is along guide and limit mechanism displacement is respectively at vertical direction or level The center line of direction position, such stator A can be overturn from horizontal direction to vertical direction, and the overturning of stator A is convenient, not only The end of the line packet and engine base that avoid the ends stator A is collided with, and ensures the total quality after motor assembly, in addition, this dress Can equally engine base be overturn by setting, it is only necessary to overturn single stator A or engine base, greatly facilitate worker's Operation, reduces the labor intensity of worker.

The lower end for constituting the steel wire rope 1 of lifting unit is connected with pulley 20 and 20 core wheel of pulley is located at horizontal direction, and rise bar 10 rear ends are connected with cradling piece 12, have bent or arcuate socket 121 on cradling piece 12 and Kong Xin is located at horizontal direction, pulley 20 is set In composition guide and limit mechanism in bent or arcuate socket 121.

The upper end of steel wire rope 1 can be connected with driving, and the leading portion for the bar 10 that rises is inserted in stator A cavitys and fixed stator A, Operating personnel, which push directly on, rises by bar 10 and cradling piece 12 makes pulley 20 be slided along bent or arcuate socket 121, can will determine in this way The center line of sub- A is overturn by horizontal direction to vertical direction, and not only the overturning of stator A is very convenient, but also the structure of the present apparatus Simply, easily manufactured.

There is race on 20 wheel rim of pulley, the hole wall profile of wheel channel profiles and arcuate socket 121 on 20 wheel rim of pulley It coincide.Ensure that pulley 20 can only be slided along arcuate socket 121, guarantee pushes can be steadily when rising by bar 10 and cradling piece 12 The center line of stator A is overturn by horizontal direction to vertical direction.

In order to which easily pulley 20 is placed in arcuate socket 121,121 one end of arcuate socket on the cradling piece 12 is in Open-like shape, pulley 20 are placed in from the open end in arcuate socket 121, and block 13 is inserted in the vestibule of 121 open end end of arcuate socket Interior, cradling piece 12 is locked with block 13 by bolt.

The 10 bar core of bar that rises when being located at 121 one end of arcuate socket of pulley 20 is horizontally oriented, and it is another that pulley 20 is located at arcuate socket 121 The 10 bar core of bar that rises when one end is in vertical direction.

As shown in Figures 2 and 3, when original state, pulley 20 is located at one end of arcuate socket 121, by the stator A of center line level Coordinate with the tensioner stick 11 for 10 leading portion of bar that rises, operating personnel only need to push cradling piece 12 that pulley 20 is made to slide to arcuate socket 121 The other end, at this time the center line of stator A slided when that is, pulley 20 is located at 121 one end of arcuate socket just at vertical direction Arc at 20 center of pulley when the tangential direction of circular arc is located at 121 other end of arcuate socket with pulley 20 where taking turns arcuate socket at 20 centers The tangential direction of circular arc is mutually perpendicular to where shape hole, and the center line of stator A is just at vertical direction, stator A after overturning in this way Overturning it is convenient and precisely, greatly reduce the labor intensity of worker.

According to the wheel footpath of pulley 20, the corresponding central angle of 121 place circular arc of general arcuate socket is slightly larger than 90 °, arcuate socket 121 Circular arc corresponding central angle alpha in place is 90 °~110 °, reduces the use of manufacture 12 material requested of cradling piece, reduces manufacturing cost.

There are two types of specific embodiments for pulley 20, specific as follows.

One is offering the through-hole through 20 both ends end face of pulley on pulley 20, steel wire rope 1 passes through logical on pulley 20 Hole is simultaneously set on pulley 20.

The second is being respectively arranged with the wheel shaft 21 of same core arrangement, steel wire rope 1 and 21 phase of two axles on 20 both ends end face of pulley Even, ensure that steel wire rope 1 is connect reliably with two axles 21.

10 one end of bar of rising is connected with 12 shaft of cradling piece on the inside of 121 arc of arcuate socket, the cradling piece on the outside of 121 arc of arcuate socket Stretching on 12 shafts has handle 14, and handle 14 is opposite with 10 extending direction of bar that rises and the two is on 10 bar core direction of bar of rising Arranged for interval, while ensureing the structural strength of 12 entirety of cradling piece, the personnel that are conveniently operated hold handle 14 and carry out turnover bracket bar 12。

The handle 14 is telescopic cannula-like, and when in use, the elongation of handle 14 is conveniently operated personnel and holds turn device Simultaneously turnover bracket bar 12 is held, after use, handle 14 shortens turn device, reduces the volume of turn device, facilitates turn device Storage.
