Changes or adjustments to their relative relationships shall be deemed to be within the scope of the present invention without substantially changing the technical content.

The specific settings are as follows:

[0054] Please refer to Figure 1 and Figure 2 The bottom support bearing structure 1 includes a bottom support body 11, a soft cushion layer 12 and a pressure pad 13; wherein, a bottom ring plate is fixedly connected to the top of the side of the bottom support body 11, and a top pressure driving cavity is formed inside the bottom ring plate of the bottom support body 11 corresponding to the bottom ring plate, and a plurality of groups of anchor pin seat structures 2 are installed at intervals on the outer side of the bottom support body 11 corresponding to the bottom ring plate, so as to stably fix the bottom support body 11 on the pier 8 through the burying effect of the anchor pin seat structure 2.

[0055] The sensor end of the dynamometer 6 is fixedly mounted on the bottom of the top pressure driving cavity of the bottom support seat body 11, and the soft cushion layer 12 is fully arranged between the sensor end of the dynamometer 6 and the inner wall of the top pressure driving cavity of the bottom support seat body 11, so as to monitor the pressure value change trend in real time through the sensor end of the dynamometer 6, and play a certain buffering role through the soft cushion layer 12; the pressure-regulating pad 13 is correspondingly arranged inside the top pressure driving cavity of the bottom support seat body 11, and the pressure-regulating pad 13 is fully arranged on the top of the sensor end of the dynamometer 6 and the top of the soft cushion layer 12, so as to realize the integrated synchronous pressure transmission by using the pressure-regulating pad 13, and avoid the pressure measurement error caused by the local pressure change.

[0056] The base of the hydraulic jack structure 4 is fixedly mounted on the top of the pressure-regulating pad 13 to effectively transmit pressure through the hydraulic jack structure 4 and to play a lifting role in the height adjustment process.

[0057] Please continue to refer to Figure 1 and Figure 2 The top pressure sleeve structure 3 includes a sleeve body 31; the pressure transmission support structure 5 includes a pressure transmission seat body 51, a locking convex plate 52 and a spherical bearing seat 53; wherein the top of the pressure transmission seat body 51 is connected to the cross beam 9 by bolts, and the bottom of the pressure transmission seat body 51 is fixedly assembled with the spherical bearing seat 53 by the locking convex plate 52; an inner concave spherical surface is arranged at the top center of the sleeve body 31, and the spherical bearing seat 53 can be slidably matched with the inner concave spherical surface of the sleeve body 31; it is used to receive pressure from different directions and / or different sizes of the cross beam 9 through the pressure transmission seat body 51 and transmit it to the spherical bearing seat 53, and further realize the transfer energy consumption effectively through the adaptive sliding action of the spherical bearing seat 53 on the inner concave spherical surface at the top of the sleeve body 31, so as to reduce the influence of the change of pressure transmission direction caused by external vibration or other factors on the overall rigidity of the support.

[0058] A top ring enclosure plate is fixedly connected to the bottom of the side of the sleeve body 31, and the top ring enclosure plate of the sleeve body 31 is vertically slidably sleeved on the outer side of the bottom ring enclosure plate of the bottom support seat body 11, so that the sleeve body 31 and its top ring enclosure plate can be vertically slid and displaced based on the bottom support seat body 11 and its bottom ring enclosure plate; the lifting kinetic energy end of the hydraulic jack structure 4 is correspondingly in contact with the bottom position of the sleeve body 31, so as to transmit pressure to the dynamometer 6 through the spherical bearing 53 in sequence through the sleeve body 31 and the hydraulic jack structure 4. When the dynamometer 6 detects that the pressure has a decreasing trend, the sleeve body 31 can be lifted by the hydraulic jack structure 4, and the sleeve body 31 can be lifted by the hydraulic jack structure 4. After jacking into place, a temporary pad is used to support the socket body 31. At this time, the hydraulic jack structure 4 is controlled to return oil, so that a gap is formed between the top of the hydraulic jack structure 4 and the socket body 31, and then a specific thickness of the raised steel plate layer is artificially filled based on the gap, and the hydraulic jack structure 4 is further controlled to be filled with oil, so that the top of the hydraulic jack structure 4 continues to maintain contact with the socket body 31, and the temporary pad is removed. The above-mentioned arrangement can effectively realize the stepless height adjustment of the support as a whole based on the specific thickness of the raised steel plate layer, and can reduce the single jacking amplitude of the hydraulic jack structure 4, thereby ensuring the jacking stability of the hydraulic jack structure 4 and retaining the jacking margin for the subsequent height adjustment process.

[0060] As another preferred scheme of the present embodiment, the concave spherical surface of the sleeve body 31 is also fixedly provided with a curved substrate 33, the top surface of the curved substrate 33 is higher than the concave spherical surface of the sleeve body 31, and the curved surface material of the curved substrate 33 can be but not limited to a stainless steel surface layer, so as to avoid direct contact between the spherical bearing 53 and the concave spherical surface of the sleeve body 31 through the curved substrate 33, thereby reducing the friction of the rotation, and the smooth performance of the stainless steel surface layer can be used to improve the functional stability of the support during adaptive switching.

[0061] More preferably, please refer to Figure 3 The arc surface of the arc substrate 33 is provided with a plurality of accumulation grooves 331, which can ensure the smoothness of the adaptive rotation of the spherical bearing 53 and push the dust impurities to the plurality of accumulation grooves 331 through the rotation and switching friction, thereby further improving the switching performance.

[0062] Please continue to refer to Figure 1 and Figure 2 The outer side of the sleeve body 31 can also be detachably fixedly assembled with a limit baffle structure 7 to effectively ensure the overall protection performance by using the limit baffle structure 7.

[0063] Please refer to Figure 4 and Figure 5 The embodiment of the utility model also provides a construction framework of a force monitoring and height adjustment support based on a continuous beam bridge, comprising: a pier 8, a span beam 9 and the force monitoring and height adjustment support based on the continuous beam bridge; wherein the top of the pier 8 is arranged along the transverse direction of the bridge, and a plurality of groups of pedestal seats are fixedly arranged on the top of the pier 8, the span beam 9 is arranged as a box beam structure, and a plurality of groups of box beam bases are provided at the bottom of the span beam 9; the plurality of groups of pedestal seats at the top of the pier 8 and the plurality of groups of box beam bases at the bottom of the span beam 9 are arranged one-to-one in correspondence, and two groups of force monitoring and height adjustment supports based on the continuous beam bridge are fixedly arranged correspondingly between each group of the pedestal seats and each group of the box beam bases.

[0064] Please continue to refer to Figure 1 and Figure 2 , Figure 4 and Figure 5 An adaptive gap portion 54 is formed between the sleeve body 31 and the pressure transmission seat body 51 corresponding to the transverse direction of the bridge, and a limited position constraint portion 55 is formed between the sleeve body 31 and the pressure transmission seat body 51 corresponding to the longitudinal direction of the bridge, so as to effectively adapt to the supporting force changes between several groups of box beam bases arranged in the transverse direction of the span beam 9, thereby improving the overall functional adaptability.
