[0027] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are only a part of the embodiments of this application, not all of them. The specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0028] The present invention provides a rotating system with force measurement and stable support functions.
[0029] like Figure 1 and Figure 2 As shown, one embodiment of this utility model provides a rotating system with force measurement and stable support functions, including a rotating support 3 disposed between an upper support 1 and a lower support 2; characterized in that it further includes an upper slide rail 4 disposed on the bottom surface of the upper support 1 and a plurality of height-adjusting force-measuring fixing support devices 5 circumferentially distributed on the outer side of the rotating support 3; the height-adjusting force-measuring fixing support device 5 includes a height-adjusting force-measuring base 51 and a support component 52, the support component 52 being disposed above or below the height-adjusting force-measuring base 51; the height-adjusting force-measuring base 51 includes a lower base plate 511 and an upper base plate 52. The upper seat plate 511 is mounted on the lower support platform 2 or the support component 52 and faces the upper slide rail 4. The upper part of the lower seat plate 511 has an annular basin structure, and the bottom of the upper seat plate 512 has an annular boss structure. The bottom of the upper seat plate 512 is inserted into the lower seat plate 511. The elastic layer 513 is built into the basin of the lower seat plate 511 and fits tightly. The elastic layer 513 is located below the upper seat plate 512. The bottom pad 514 is fixed to the lower surface of the lower seat plate 511. The height-adjusting force-measuring fixed support device 5 is used to contact the upper slide rail 4.
[0030] Specifically, in this embodiment, the elastic layer 513 can be made of rubber.
[0031] This embodiment provides a rotating system with force measurement and stabilizing support functions. Compared with the prior art, when the tonnage of the rotating bridge is large and the unbalanced moment is also large, the upper pier 1 presses down on the support component 52 or the upper seat plate 512 in an inclined direction. The support component 52 or the upper seat plate 512 tilts relative to the lower seat plate 511 and squeezes the elastic layer 513. The elastic layer 513 can ensure full contact and stable force of the support component 52 or the upper seat plate 512 through deformation. At the same time, it transmits the unbalanced force during the rotation to the lower pier 2, so that the height-adjusting force-measuring fixed support device 5 can maintain its fit with the upper slide rail 4, thereby improving the stability of the normal rotation.
[0032] like Figures 2 to 4 As shown, based on the above embodiments, this utility model provides another specific embodiment as follows:
[0033] The support component 52 includes a support column 521, a top plate 522, a bottom plate 523, and a connector 524. The support column 521 is fixed to the upper surface of the bottom plate 523, the top plate 522 is fixed to the upper surface of the support column 521, and the bottom plate 523 and the upper seat plate 512 are detachably fixed together by the connector 524.
[0034] Specifically, in this embodiment, the support column 521 is a steel pipe filled with concrete, steel grit or quartz sand, or it can be solid or other structures that can provide rigid support. The area of the top plate 522 is larger than the top area of the support column 521, which can improve the support effect on the upper support platform 1.
[0035] Furthermore, in this embodiment, the connecting member 524 is a bolt and a nut. The bolt passes through the base plate 523, the pad 53 and the upper seat plate 512 in sequence and then connects with the nut.
[0036] The height-adjusting force-measuring fixed support device 5 also includes a pad 53, which is inserted between the base plate 523 and the upper seat plate 512. At this time, the top plate 522 is pressed against the bottom surface of the upper slide rail 4.
[0037] During the rotation installation, the pad 53 is located between the base plate 523 and the upper seat plate 512. At this time, the top of the top plate 522 is in close contact with the upper slide rail 4, which can improve the stability of the rotation support 3 when the upper support platform 1 and above components are poured. It also has the function of a regular sand box in conventional rotation, which can replace the sand box and save material and labor costs.
[0038] When preparing to rotate, the pad 53 is pulled out after the connector 524 is removed, and the support component 52 is rotated 180° so that the inclined surfaces of the bottom plate 523 and the upper seat plate 512 match and fit together. Then, the bottom plate 523 and the upper seat plate 512 are fixed by the connector 524. At this time, there is a gap between the top of the top plate 522 and the upper slide 4, which facilitates subsequent operations such as bridge posture adjustment.
[0039] In some possible embodiments, the upper and lower surfaces of the pad 53 may also be planar.
[0040] like Figures 2 to 4 As shown, based on the above embodiments, this utility model provides another specific embodiment as follows:
[0041] The height-adjusting force-measuring fixed support device 5 also includes a slide plate 54, which is fixed to the upper surface of the top plate 5212.
[0042] refer to Figure 7 In some possible embodiments, the support member 52 may be a concrete pad that protrudes upward from the lower support 2, in which case the slide plate 54 is fixed to the upper surface of the upper seat plate 512.
[0043] like Figures 4 to 6 As shown, based on the above embodiments, this utility model provides another specific embodiment as follows:
[0044] The lower base plate 511 has an injection hole 5112 on its inner bottom wall and an oil injection hole 5113 connected to the injection hole 5112 on its outer side. A sealing member 5114 is inserted into the outer end of the oil injection hole 5113. The sealing member 5114 can be a rubber plug or a bolt. When the sealing member 5114 is a bolt, the oil injection hole 5113 is a threaded hole.
[0045] Before rotating the body and after removing the pad 53, if the gap between the top of the top plate 522 and the upper slide rail 4 is large, the sealing part 5114 can be removed, and liquid filling medium a can be injected into the oil injection hole 5113. The filling medium a enters the bottom of the lower seat plate 511 after passing through the oil injection hole 5113 and the filling hole 5112, and lifts up the elastic layer 513, the upper seat plate 512 and the support component 52, thereby reducing the gap between the top of the top plate 522 and the upper slide rail 4, and realizing the height adjustment function of the height-adjusting force-measuring fixed support device 5.
[0046] like Figure 2 As shown, based on the above embodiments, this utility model provides another specific embodiment as follows:
[0047] The lower seat plate 511 has several side openings 5115 on its side or bottom surface, or the bottom surface of the upper seat plate. The side openings 5115 contain force measuring units that contact the side, bottom, or top surface of the elastic layer 513.
[0048] Specifically, in this embodiment, the force measuring unit 5116 can be a pressure sensor. One or more force measuring units 5116 can be set in a single height-adjusting force measuring fixed support device 5. Through the force measuring units 5116 on multiple sets of height-adjusting force measuring support devices 5, the entire rotation construction process can be monitored.
[0049] Before the formal rotation, the bridge needs to be weighed and counterweighted to ensure that the eccentricity of the bridge's center of gravity is within the specified range. The force measuring unit 5116 built into the height-adjusting force-measuring fixed support device 5 can monitor the force on the elastic layer 513 in real time with digital display. The eccentricity of the bridge's center of gravity can be calculated based on the digital display of the force measuring unit 5116, and the bridge counterweight can be calculated accordingly. During the counterweighting process, the force measuring unit 5116 can still monitor in real time to ensure that the counterweighting work can achieve the predetermined effect. During the formal rotation construction, the force on the height-adjusting force-measuring fixed support device 5 can also be monitored, providing a scientific basis for the safe rotation work.
[0050] like Figure 2 As shown, based on the above embodiments, this utility model provides another specific embodiment as follows:
[0051] The upper slide rail 4 includes an annular slide rail plate 41, anchoring steel bars 42, and stiffening plates 43. The anchoring steel bars 42 and stiffening plates 43 are alternately fixed to the top surface of the upper slide rail 4 and are both fixed to the upper support platform 1. This improves the firmness between the upper slide rail 4 and the upper support platform 1.
[0052] like Figure 2 As shown, based on the above embodiments, this utility model provides another specific embodiment as follows:
[0053] A ring-shaped stainless steel plate 411 is fixedly installed on the bottom surface of the annular slide plate 41. The stainless steel plate 411 extends the service life of the annular slide plate 41.
[0054] like Figure 2 As shown, based on the above embodiments, this utility model provides another specific embodiment as follows:
[0055] The lower base plate 511 is connected to the lower support platform 2 by anchor bolts 21. The lower base plate 511 can be disassembled by the anchor bolts 21 to enable repeated use of the height-adjusting force-measuring fixed support device 5.
[0056] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
