Connect, be socketed on the externally threaded screw thread of first screw rod 8 in inner thread sleeve 7, upper end and the axle of motor 12 of the first screw rod 8 connect
Connect, the bottom of the first screw rod 8 has the internal thread hole 13 of lower ending opening (referring to Fig. 4).
Referring to accommodating chamber 14 is offered on the ground immediately below Fig. 2-3, the first screw rods 8, fixed metal sleeve 15 is fixed on
On the bottom wall of accommodating chamber 14, it is connected with contact plectane 9 with externally threaded second screw rod 16, the second screw rod 16 can screw thread rotation set
Enter in internal thread hole 13, the first side channel 17 vertically offered on contact plectane 9, offered on fixed metal sleeve 15 width with
The second suitable side channel 18 of first side channel 17.
The first electric expansion bar 19, the first electric expansion bar are connected with the side wall relative with the second side channel 18 of accommodating chamber 14
19 other end is connected with the first screens block 20, and the first screens block 20 can stretch into 18, first in the first side channel 17 and the second side channel
The lateral surface of screens block 20 is provided with RFID inductors 21, the inwall of the first side channel 17 and is connected with RFID label tag 22, works as contact
The bottom surface of plectane 9 is contacted with the bottom wall of accommodating chamber 14 and when the first side channel 17 and the second 18 counterpart of side channel, and RFID inductors 21 are just
Pair and can sense RFID label tag 22.
Rectangular channel 23 is offered referring to the upper end of Fig. 4-5, the second screw rods 16, and the first screw rod 8 is embedded with second and electronic stretched
Contracting bar 24, the end of the second electric expansion bar 24 is connected with the second screens block 25 that cross section is rectangle, and plectane 9 is contacted when utilizing
When contacting upwards and lift side wing 6, the second screens block 25 is stretched into rectangular channel 23 under the driving of the second electric expansion bar 24；
Tangent displacement sensor 26 is connected with the roof of the internal thread hole 13.
It should be noted that electric expansion bar is the retractor device with built-in motor, belong to prior art category.
As further preferred scheme, the internal diameter of the fixed metal sleeve 15 is suitable with the external diameter for contacting plectane 9.Gu
The effect for determining metal sleeve 15 is that the position in the horizontal plane for ensureing contact plectane 9 is fixed.
As further preferred scheme, the length of the internal thread hole 13 is identical with the length of the second screw rod 16, described
Contact the diameter with diameter greater than through hole 10 of plectane 9.
As further preferred scheme, first screw rod 8 passes through inner thread sleeve 7.The end of substrate 2, which is connected with, to be climbed
Ramp 28.
As further preferred scheme, the hydraulic jack 4 is provided with four, is arranged in the form of corner is arranged
The lower section of substrate 2.
As further preferred scheme, first electric expansion bar 19 is arranged at the expansion link connected with accommodating chamber 14
In room 27.Each leg 11 passes through the affixed (not shown) of 8 bolt flanges with ground.
The lift is additionally provided with controller, the controller respectively with the first electric expansion bar 19, the second electric expansion
Bar 24, motor 12, RFID inductors 21 are electrically connected or radio communication, and the expression for view is clear, and control is eliminated in figure
The particular location of device and electrical connection.
The method of work of the lift is：It is normal in use, the second screw rod 16 rotation set, will in inner thread sleeve 7
Automobile drives upper substrate 2, and automobile using the jack-up substrate 2 of hydraulic jack 4 and thereon from climbing plate 28, after rising in place, drives
Dynamic motor 12, which is rotated forward, make it that the first screw rod 8 rises under the cooperation of inner thread sleeve 7, when contact plectane 9 touches flank
Stop motor 2 during plate 6, now use contact plectane 9 as the secondary supporting construction of hydraulic jack 4, even if hydraulic jack
Top 4 is failed, and can also be used as support by contact plectane 9 temporarily.
When needing to change contact plectane 9, motor 12, which is reversely rotated, first causes the first contact with old of screw rod 8 circle
Plate 9 is fallen, and contact plectane 9 is entered in accommodating chamber 14 and fixed metal sleeve 15 (upper end open of fixed metal sleeve 15),
When contacting plectane 9 and declining and rotate the position to the first side channel 17 and the counterpart of the second side channel 18 (position i.e. shown in Fig. 2),
RFID inductors 21 can just carry out sensing identification to RFID label tag 22, and RFID inductors 21 will by built-in wireless transceiver
Signal is sent to controller, and controller controlled motor 12 is stopped transport, and drives the first electric expansion bar 19 to stretch out the first screens block
20 are caught in the second side channel 17, and then motor 12, which is rotated forward, lifts the first screw rod 8, now because contact plectane 9 is by card
Firmly can not concomitant rotation, therefore the first screw rod 8 separates with the second screw rod 16, and old contact plectane 9 is left on accommodating chamber 14
In；Now operating personnel take out old contact plectane 9, and new contact plectane 9 is put into, and the identification of RFID inductors 21 is sensed
After new label, controller controlled motor 12, which is reversely rotated, falls the first screw rod 8, and the rotation set of the second screw rod 16 enters internal thread hole 13
In, after tangent displacement sensor 26 is touched sends the second 16 signal in place of screw rod, the first electric expansion bar 19 drives the
One screens block 20 exits the second side channel 17, and then motor 12, which is rotated forward, lifts the first screw rod 8 contact with new plectane 9,
So far new contact plectane 9 can be used normally.
When hydraulic jack 4 fails or other reasons need directly to carry out lifting substrate 2 and thereon using contacting plectane 9
During automobile, first drive the second electric expansion bar 24 to stretch out the second screens block 25 and be caught in rectangular channel 23, then motor 12 is just
Lift the first screw rod 8 to rotation, then contact plectane 9 lift therewith, and by its contact with side wing 6 lift substrate 2 and its
On automobile.The reason for second screens block 25 is caught in into rectangular channel 23 be：Because the weight of automobile is huge, contact plectane 9
There is very big frictional force between the lower surface of upper surface and side wing 6, and from foregoing operation principle, when motor 12 just
It is towards what is rotated with the direction that the second screw rod 16 is separated to the first screw rod 8 during rotation, both are very under so big frictional force
Easily it is directly separated and can not plays a part of lifting substrate 2, and the second screens block 25 is caught in after rectangular channel 23, utilizes
Rectangular channel 23 and cross section are the clamping force between the second screens block 25 of rectangle, ensure that the second screw rod 16 will necessarily be with
The rotation of first screw rod 8 and rotate, will not occur the first screw rod 8 during lifting anyway and be separated with the second screw rod 16
Situation.
Embodiment 2
Due to automobile draining and disassemble working environment so that the lifting machine of automobile is usually faced in the presence of by flow-induced corrosion
Situation occur, therefore, in order to lifted lifting machine service life and reduction enterprise production cost, in some other embodiment party
