Description

Technical Field

[0001] The utility model relates to a bridge rotating device, in particular to a planar rotating device capable of realizing rapid installation. Background Technique

[0002] The rotating ball hinge is the core of the rotating system in rotating construction. The current rotating technology usually adopts an upper and lower spherical rotating structure, which has problems such as poor anti-overturning ability and difficulty in controlling the unbalanced moment. The rotating flat hinge has an upper and lower planar structure, which can completely avoid this problem. However, the rotating flat hinge bears the complete vertical bearing capacity during the rotation process. If there is no force measurement function, it is impossible to know the force condition of the rotating flat hinge and the balance condition of the bridge during the rotation process, which poses a construction hazard. In addition, after the rotating flat hinge is installed, it is necessary to continue pouring the pier body and the rotating bridge body, and this process takes up to half a year or even more than a year; if there is a settlement problem of poor compaction in the foundation pit during the process, it is necessary to use a jack to jack up the entire rotating bridge after the rotation is completed and pad the support structure to adjust the rotating bridge deck to be at the same horizontal height as the docking bridge deck. This operation process is very complicated and there are safety hazards. Moreover, the currently used slideways generally require very deep foundation pits to be poured with concrete in two times for installation, which is laborious and time-consuming.

[0038] Embodiment 2

[0039] like Figure 2 , Figure 7As shown, the difference between this embodiment and the first embodiment is that a force-measuring height-adjusting mechanism is provided on the lower seat plate 5 of this embodiment. The force-measuring height-adjusting mechanism includes a pressure sensor 14, an oil passage 15, a pressure strain gauge 16, an airbag 17, a height-adjusting injection pipeline 18, and a plug 19. A groove is provided on the bottom surface of the lower seat plate 5 along the thickness direction. The pressure strain gauge 16 of the pressure sensor 14 is accommodated in the groove. An airbag 17 is provided in the lower seat plate 5 above the groove. The airbag 17 is located between the rubber plate 4 and the bottom surface of the depression and presses on the pressure strain gauge 16. The oil passage 15 and the height-adjusting injection pipeline 18 are respectively opened on the lower seat plate 5. One end of the oil passage 15 communicates with the bottom of the groove. A monitoring medium is injected and discharged through the oil passage 15 to form a monitoring medium film between the pressure strain gauge 16 and the bottom of the groove. A pressure sensor 14 is installed at the other end of the oil passage 15 after the monitoring medium is injected. The oil passage 15 of this embodiment can be one or more. When there are multiple oil passages, they are evenly arranged along the circumferential direction of the lower seat plate 5. A pressure sensor 14 is installed at each oil passage 15 after the monitoring medium is injected. The monitoring medium of this embodiment is silicone oil. One end of the height-adjusting injection pipeline 18 is connected to the inside of the airbag 17 and is located outside the monitoring medium film. A plug 19 is provided at the other end of the height-adjusting injection pipeline 18. A height-adjusting medium is injected into the airbag 17 through the height-adjusting injection pipeline 18, thereby realizing the height adjustment of the rotating body flat hinge. The height-adjusting injection pipeline 18 of this embodiment can be one or more. When there are multiple height-adjusting injection pipelines, they are evenly arranged along the circumferential direction of the lower seat plate 5. The specific number of the height-adjusting injection pipelines 18 depends on the number of times of height adjustment required during the use of the rotating body flat hinge. When there are multiple height-adjusting injection pipelines 18 and oil passages 15, each height-adjusting injection pipeline 18 and oil passage 15 are arranged alternately. The height-adjusting medium of this embodiment is a single-component thermoplastic material, such as low-density polyethylene resin (HP—LDPE) produced by Shanghai Yuanye Bio-Technology Co., Ltd., with a density of 0.918 g / cm³ and a melting point of 105-115 °C, being solid at room temperature and liquid after heating; or it is an AB-component high-molecular prepolymer material, such as HC—5261AB produced by Shanghai Hecheng High-Molecular Technology Co., Ltd. Before filling, the AB components are respectively liquids, and after filling, the AB components are mixed and can be cured into a solid. Whether the height-adjusting medium is single-component or double-component, the hardness IRHD after curing is less than 60, and the bearing strength is greater than 45 MPa. The height-adjusting medium of this embodiment is an AB-component high-molecular prepolymer material, with a hardness of 1RHD 50 and a bearing strength of 60 MPa after curing.

[0040] This embodiment can monitor the force on the rotating hinge during the rotation process in real time, and conduct fault warning and emergency management through real-time monitoring. Specifically, a sealed oil cavity channel (i.e., oil circuit 15) is designed inside the lower seat plate 5, a set amount of hydraulic oil is poured into the oil circuit 15, a pressure sensor 14 is installed at the external port of the oil circuit 15, and the pressure received by the rotating hinge is transmitted to the pressure sensor 14 through the monitoring medium film to achieve the force monitoring function. Since the hydraulic oil in the oil circuit 15 is of a fixed quantity, the bearing capacity received by the rotating hinge can be accurately reflected on the pressure sensor 14.

[0041] The height adjustment function of this embodiment can solve the problem of the same height between the rotating bridge deck and the docking bridge deck caused by pier settlement. Specifically, a height adjustment material perfusion channel (i.e., height adjustment injection pipeline 18) is designed inside the lower seat plate 5. One end of this height adjustment material perfusion channel is connected to the airbag 17 placed in the inner cavity of the lower seat plate 5, and the other end is sealed with a plug 19. When height adjustment operation is required, the plug 19 is removed, and a height adjustment medium is poured into the airbag 17 using a high-pressure pump. The airbag 17 has very high toughness and ductility, and as the height adjustment medium is filled, the airbag 17 is expanded to fill the entire bottom of the inner cavity of the lower seat plate 5, realizing the height adjustment of the rotating hinge.

[0042] The rest is the same as in Embodiment 1.

[0043] Embodiment 3

[0044] As Figure 3 shown, the difference between this embodiment and Embodiment 1 is that the rotating hinge in this embodiment has a double rotating surface. The structure of the double rotating surface can further reduce the hidden danger of the failure of the rotation with a single rotating surface. The selection between the double rotating surface structure in this embodiment and the single rotating surface structure in Embodiment 1 can be designed according to the tonnage of the rotating bridge and the actual working conditions.

[0045] The rotating flat hinge of this embodiment includes an upper seat plate 1, a sliding plate 2, an upper liner 11, a lower liner 13, a rubber plate 4, a lower seat plate 5 and an anchor bolt 6. A plurality of U-shaped mounting holes 28 are formed in the outer edge of the upper seat plate 1 along the circumferential direction. Each U-shaped mounting hole 28 is connected to the upper bearing platform 7 through an anchor bolt 6 and an anchor nut 30. A gasket 29 is sleeved on the anchor bolt 6 between the anchor nut 30 and the upper seat plate 1. A plurality of U-shaped mounting holes 28 are formed in the outer edge of the lower seat plate 5 along the circumferential direction. Each U-shaped mounting hole 28 is connected to the lower bearing platform 8 through an anchor bolt 6 and an anchor nut 30. A gasket 29 is sleeved on the anchor bolt 6 between the anchor nut 30 and the lower seat plate 5. The middle of the lower seat plate 5 is recessed downward along the height direction. The lower surface of the upper seat plate 1 is provided with a downward protruding annular protrusion. The axial section of the upper liner 11 is in a "T" shape. The horizontal side of the "T" shape is located inside the annular protrusion, and the vertical side of the "T" shape is inserted into the recess of the lower seat plate 5. The rubber plate 4, the lower liner 13 and the upper liner 11 are sequentially accommodated in the recess of the lower seat plate 5 from bottom to top. The upper surface of the upper seat plate 1 is fixedly connected to the upper bearing platform 7 through an anchor bolt 6. Sliding plates 2 are respectively provided between the lower surface of the upper seat plate 1 and the upper surface of the upper liner 11 and between the lower surface of the upper liner 11 and the upper surface of the lower liner 13. The upper surface of the upper liner 11 and the upper surface of the lower liner 13 are both provided with sliding plate grooves, and the lower part of the sliding plate 2 is accommodated in the sliding plate grooves. The rest are the same as those in Embodiment 1.

[0046] Embodiment 4

[0047] As Figure 4 shown, the difference between this embodiment and Embodiment 3 is that a force-measuring height-adjusting mechanism is provided on the lower seat plate 5 of this embodiment, and the force-measuring height-adjusting mechanism is the same as that in Embodiment 2.

[0083] As Figure 13 shown, the slideway 10 before optimization is composed of a slideway skeleton and a slideway plate. The installation of this kind of slideway requires pouring concrete in the foundation pit twice for installation. The main reasons are two aspects: one is that the slideway skeleton is welded by multiple angle steel profiles, and it is impossible to ensure the flatness of the overall bottom surface, and direct installation cannot ensure the flatness of the slideway; the other is that if the slideway is directly placed in the foundation pit for concrete pouring and fixing, there will be problems of displacement and misalignment caused by uneven force during the pouring process. Therefore, the installation of this kind of slideway requires additional positioning angle steel 26 for pre-positioning, and then the installation operation is completed by pouring again. The specific steps are as follows: during the first pouring, the positioning angle steel 26 needs to be embedded in the concrete. After the concrete dries, place the slideway on the top surface of the concrete poured for the first time, and weld and fix the slideway skeleton and the embedded positioning angle steel 26, and then complete the slideway installation by the second pouring.

[0084] The plane rotating device capable of realizing rapid installation of the present invention, its rapid installation is mainly reflected in the optimized slideway structure. The present invention optimizes the slideway in the rotating device, which can not only improve the installation speed, but also reduce the depth dimension of the foundation pit, further reducing the overall cost and construction period of the project.

[0085] The specific operation of installing the lower seat plate 5 in the swivel flat hinge on the lower bearing platform 8 in step B is as follows:

[0086] Step B1: When pouring the lower bearing platform 8, a bearing pad stone is poured at the same time, and the bearing pad stone is higher than the upper surface of the lower bearing platform 8; anchor bolt reserved holes on the lower seat plate 5 are reserved on the upper surface of the concrete of the lower bearing platform 8;

[0087] Step B2: Adjust the height difference at the four corners of the bearing pad stone to the process requirements. The height of the bearing pad stone should be lower than the design height, and the concrete strength grade of the poured bearing pad stone is not lower than C50;

[0088] Step B3: Install the anchor bolts 6 and sleeves on the lower seat plate 5 on the site on the lower bearing platform 8, and try to install them when there is no epoxy resin mortar to confirm that the position of the reserved hole is correct;

[0089] Step B4: Chip the surface of the bearing pad stone at the position where the bearing is to be placed, remove the sundries and accumulated water in the reserved hole, and wet the surface of the bearing pad stone with water;

[0090] Step B5: Wedge the lower seat plate 5 at the four corners with wedges, place and level the lower seat plate 5, adjust the lower surface of the lower seat plate 5 to the design elevation, leave a gap between the lower surface of the lower seat plate 5 and the bearing pad stone, and install the formwork for grouting;

[0091] Step B6: Mix the components according to the calculated dosage of the epoxy resin mortar and stir well. Pile up all the stirred epoxy resin mortar at the center of the position where the lower seat plate 5 is to be placed. Slowly lower the lower seat plate 5 into place, and flatten the epoxy resin mortar by relying on the self-weight of the lower seat plate 5. Note that the epoxy resin mortar cannot enter the reserved hole of the sleeve. Check that the height difference at the four corners of the upper surface of the lower seat plate 5 does not exceed the design requirements before the epoxy resin mortar solidifies;

[0092] Step B7: Mix the components according to the calculated dosage of the non-shrinkage high-strength grouting material and stir well. Fill the reserved hole with the grouting material by means of gravity grouting and tamp it until it is observed from the edge gap of the lower seat plate 5 that the grouting material is completely filled.

[0093] It should be noted that before grouting, the required volume of grout should be preliminarily calculated, and the actual amount of grout used for perfusion should not have a large error from the calculated value. Intermediate lack of grout should be prevented, and the compressive strength requirement of epoxy resin mortar should not be less than C50. After the grout under the lower seat plate 5 solidifies, remove the formwork and the four corner wedges, check for any grout leakage, and if necessary, replenish the grout at the leakage point and fill the voids left after the wedges are removed with epoxy resin mortar. Tighten the anchor bolts 6 on the lower seat plate 5; before the construction of the upper bearing platform 7 of the rotating hinge, protective measures should be taken at the gap between the upper seat plate 1 and the lower seat plate 5 to prevent foreign objects from entering the rotating hinge before the bridge rotates and to protect the sliding surface of the rotating hinge; the protective measures can be to fix a dust-proof cover around the upper seat plate 1 to cover the gap between the upper seat plate 1 and the lower seat plate 5, or to seal the gap between the upper seat plate 1 and the lower seat plate 5 by winding tape. After the upper bearing platform is grouted, before the rotating hinge rotates, timely remove the anchor bolts 6 connecting the upper seat plate 1 and the lower seat plate 5 to complete the installation.
