Horizontal jitter occurs in adjustment process for plate 1, ensure that the stability that jacking is adjusted.
A kind of jacking provided in an embodiment of the present invention is provided by setting extension adjustment device for the first telescopic device
Another mode for adjusting jacking, extension adjustment device include studdle 23 and support adjusting block 24, can according to first
The pressure value of pressure sensor 5 adjusts the bearing height for supporting position of the adjusting block 24 on studdle 23 to adjust supporting plate 1,
So as to adjust the load that supporting plate 1 applies support plate 2, support degree deficiency is avoided to influence support effect or jacking overload
The case where damaging to jacking improves the support effect of jacking and the service life of jacking；And by being adjusted in support
Thrust bearing 26 is set between locking nub 24 and first pressure sensor 5, it is possible to prevente effectively from support adjusting block 24 is in adjustment process
In first pressure sensor 5 is caused to wear, improve first pressure sensor 5 service life, while reduce support adjust
The frictional force that block 24 is subject in adjustment process facilitates the adjusting of support adjusting block 24.
It as shown in Figure 3,4, is a kind of jacking for being provided with the second support device provided in an embodiment of the present invention, the supporting plate
The second support device is additionally provided between 1 and the support plate 2, second support device is used to adjust 1 He of supporting plate
The supporting plate 1 is supported when the distance between described support plate 2 and the supporting plate 1 is driven to move up and down.Second support device
Second pressure sensor 6 is additionally provided between the support plate 2.
In embodiments of the present invention, the second support device can be jack structure, such as can be ultrathin type jack
7, the embodiment of the present invention illustrates so that the second support device is ultrathin type jack 7 as an example.When the first support device carries out supporting plate 1
When support, the top of ultrathin type jack 7 is not contacted with supporting plate 1, or is in critical contact state, so that it does not play supporting plate 1
Supporting role；When overloading occurs in jacking or when underload, needs to adjust the bearing height of jacking, extension adjustment device unloads shape at this time
It can be more convenient to adjust under state, temporary support can be carried out to jacking by setting ultrathin type jack 7.Preferably, thus it is ultra-thin
Formula jack 7 can drive supporting plate 1 to move up and down to adjust the load that supporting plate 1 applies support plate 2, while by ultra-thin
Formula jack 7 drives the appropriate position that can judge supporting plate 1 when the up and down motion of supporting plate 1 by the influence value of second pressure sensor 6
It sets.
A kind of jacking provided in an embodiment of the present invention, by the way that ultrathin type jack 7 is arranged between supporting plate 1 and support plate 2,
And second pressure sensor 6 is set between ultrathin type jack 7 and support plate 2, supporting plate 1 is driven by ultrathin type jack 7
Move up and down bearing height to adjust jacking when, can judge supporting plate 1 to the application of support plate 2 by second pressure sensor 6
Load, to determine the rational position of supporting plate 1, to realize that jacking easily and fast, is accurately adjusted, to avoid jacking underload
Or the case where overload.
A kind of jacking provided in an embodiment of the present invention uses operating procedure:, will be provided by the present application before concrete construction
Jacking is mounted on the support tube of scaffold, then during concrete construction, according to the data monitoring jacking of pressure sensor
Stress condition.
When the load for detecting supporting plate 1 and applying to support plate 2 is too small, release locking system 25 first to release locking,
Then starting ultrathin type jack 7 rises, it is made to be in close contact the induction pressure until first pressure sensor 5 with 1 bottom of supporting plate
Power numerical value is zero, and then proceeding to adjusting ultrathin type jack 7 makes its that supporting plate 1 be driven slowly to rise；When second pressure sensor 6
After induction pressure value is met the requirements, stop the jacking of ultrathin type jack 7, since studdle 23 is fixedly connected with supporting plate 1, and
Support adjusting block 24 is further through setting is threadedly engaged on studdle 23, in the mistake that ultrathin type jack 7 drives supporting plate 1 to rise
Cheng Zhong, studdle 23 and support adjusting block 24 can also rise with supporting plate 1；After the jacking for stopping ultrathin type jack 7, to
Lower mobile support adjusting block 24 after contacting with thrust bearing 26 up to being tightened；Then by 25 locking of locking system, work as lock
Locking apparatus 25 is self-locking nut, that is, is adjusted up self-locking nut to the thrust between support plate 2 or self-locking nut and support plate 2
Bearing 26 contacts；Finally the adjusting that jacking is completed in the unloading of ultrathin type jack 7 is operated.
When the load for detecting supporting plate 1 and applying to support plate 2 is excessive, release locking system 25 first to release locking,
Then starting ultrathin type jack 7 rises, it is made to be in close contact the induction pressure until first pressure sensor 5 with 1 bottom of supporting plate
Power numerical value is zero, then unscrews and adjust supporting block 24, and moves a certain distance adjusting supporting block 24 to 1 direction of supporting plate, is then adjusted
Section ultrathin type jack 7 makes it that supporting plate 1 be driven slowly to decline, after the induction pressure value of second pressure sensor 6 is met the requirements,
The decline for stopping ultrathin type jack 7 is adjusted, and mobile support adjusting block 24 with thrust bearing 26 until by it after contacting still further below
It tightens；Since self-locking nut and studdle 23 are threadedly engaged, during ultrathin type jack 7 drives supporting plate 1 to decline, branch
Support screw rod 23 and self-locking nut can decline together in company with supporting plate 1, therefore need after the decline for stopping ultrathin type jack 7 is adjusted
The thrust bearing 26 that turning self-locking nut rises to it between support plate 2 or self-locking nut and support plate 2 contacts；Finally will
The adjusting operation of jacking is completed in the unloading of ultrathin type jack 7.
The present invention program realizes supporting plate 1 by the cooperation of ultrathin type jack 7, support adjusting block 24 and self-locking nut
Adjusting control, the stress underload to jacking or overload situations can make reply in time.
As shown in fig. 6, another embodiment of the present invention additionally provides a kind of jacking stress monitoring system, the system comprises
Above-mentioned jacking and monitor client 8, the first pressure sensor 5 and the monitor client in the jacking connect
The load data for connecing 8, and being incuded is sent to the monitor client 8, and the monitor client 8 is provided with display unit,
The display unit is for showing the load data.
In embodiments of the present invention, monitor client 8 can be desktop computer, smart phone, tablet computer, notebook
Computer etc., the embodiment of the present invention with no restrictions, can receive the load data of first pressure sensor 5 and can be by load
Data are shown.When being additionally provided with second pressure sensor 6 in the jacking, second pressure sensor 6 also with monitoring client
8 connection of end, and the load data incuded is sent to the monitor client 8.
A kind of jacking stress monitoring system provided in an embodiment of the present invention, the top including being provided with first pressure sensor 5
Support and the monitor client 8 connecting with the first pressure sensor 5 in the jacking, can be known by monitor client 8
The load condition that supporting plate 1 applies support plate 2, and then the bearing height by adjusting jacking is imitated with the support for improving jacking
Fruit, and avoid overload to part is supported and formwork bracing system damages, it effectively avoids support from collapsing, improves construction site
Safety guarantee.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
