Structure, practical cost and manufacture cost can be controlled preferably.
As depicted in figs. 1 and 2, be fixedly linked at the top of the upper end of drive screw 3 and wall, the lower end of drive screw 3 with
There is gap between ground；There is a certain distance in 3 downside of drive screw with ground, and drive screw 3 is made to be in nature vertical hanging
State bears tensile stress state always, ensures the straightened condition of screw rod, external carbuncle is avoided to act on, and causes 3 torque of drive screw
Deformation.
As shown in figures 1 to 6, the upper and lower ends of casing 21 are both provided with a location structure, and location structure includes being set in
Thread bush 51 on two drive screws 3, thread bush 51 are arranged with a bearing outside, are fixed between two bearings by a connecting rod 52
It is connected, is connected between connecting rod 52 and casing 21 by a column 53；In order to ensure the high-precision between rotor 22 and drive screw 3
Cooperation, is both provided with a location structure, which can ensure drive screw 3 urgently in the two side portions up and down of casing 21
The section of transmission keeps straight.
As shown in Fig. 2, drive screw 3 includes several monomer bars 31, welded between each monomer bar 31, the both ends of monomer bar 31
With smooth department 32, the length of smooth department 32 is less than the half of 22 height of rotor；Rotor 22 can be accepted outer on drive screw 3
Screw thread designs length of the length much larger than the non-threaded area of drive screw 3 of 22 internal thread of rotor, when rotor 22 is transported in the design
Non-threaded area can steadily be tided over by screw thread official post elevator safety herein by moving.
One whole screw rod length is generally 9m, a 31 a length of 3m of monomer bar；3 downside of drive screw is general with the distance on ground
For 5-10mm.
As shown in Figure 1 and Figure 7, this elevator further includes frequency converter, the position sensor for corresponding to each floor position, answers urgent telegram
Source, hydraulic cylinder and unilateral bearing, unilateral bearing are provided with one for connecting casing 21 and rotor 22 on the main efferent duct of hydraulic cylinder
Solenoid valve, frequency converter, position sensor and solenoid valve are connected with emergency power supply, and unilateral bearing includes inner ring 61 and is set in interior
The outer ring 62 on 61 is enclosed, warp-wise is uniformly provided with several straight slots 63 on outer ring 62, is offered in outer ring 62 and straight slot 63 1 is a pair of
The avoid holes 64 answered, avoid holes 64 are communicated with corresponding straight slot 63, and a sliding block 65 is slidably connected in straight slot 63, is had on sliding block 65
Have a limiting section 651, the both ends of limiting section 651 are respectively provided with a movable part 652 being located on sliding block 65, limiting section 651 with it is interior
Enclose the gap that the gap between 61 outer walls is less than between 61 outer wall of movable part 652 and inner ring, and the activity of limiting section 651 and both sides
It is seamlessly transitted between portion 652, also there is a valve opening 66 on outer ring 62, pushing block 67 is slidably connected in valve opening 66, each valve opening 66 is equal
It is connected with the main efferent duct of hydraulic cylinder, has one between 61 outer wall of one of movable part 652 and inner ring in single sliding block 65
Roller 68.
The principle of unilateral bearing is：The hydraulic pressure of the main efferent duct of solenoid valve control, under normality, pushing block 67 compresses cunning always
Block 65 makes roller 68 that can only be rotated in the movable part 652 of 65 one side of sliding block, if the inner ring 61 of unilateral bearing inverts, by
To the effect of limiting section 651 and it is stuck, when unilateral bearing need change allow rotate direction when, be provided on main efferent duct
One relief valve, solenoid valve end main efferent duct, the pressure in relief valve venting valve opening 66, under the thrust of roller 68, sliding block
65 move outward, so that roller 68 can be moved in another movable part 652, then, solenoid valve continues on, and makes to push away
Block 67 can pressed slider 65, unilateral bearing complete rotation direction switching.
When having a power failure suddenly in manager, reverse drive between unilateral bearing limitation drive screw 3 and rotor 22 has self-locking work(
It can prevent car 1 from falling, frequency converter detects that external power supply occurs surprisingly automatically switching to emergency flat layer working condition at this time；It should
Urgent telegram source drive rotor 22 rotate, wherein, the system also need to set a microcontroller, for plan as a whole position sensor and stator around
Group 23, enables car 1 to move to the position of contiguous floors, and keeps stoppage in transit state.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Described specific embodiment can be done various modifications or additions or using similar by belonging to those skilled in the art
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
