[0026] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] Referring to Figures 1 - 3 , the present utility model provides a steel bearing adapted to a vertically lifting and opening bridge, including:
[0028] An intermediate steel lining plate 7, on the top of which an upper bearing plate 5 is horizontally slidably connected;
[0029] A buffer assembly, the buffer assembly includes a polymer material buffer mechanism and a spring buffer mechanism arranged on the top of the upper bearing plate 5, and an upper steel plate 1 is arranged between the spring buffer mechanism and the polymer material buffer mechanism, and the upper steel plate 1 is correspondingly arranged with the bridge girder;
[0030] A reset assembly, the reset assembly includes two groups of spring-back mechanisms, the two groups of spring-back mechanisms are respectively arranged between the two opposite side walls of the intermediate steel lining plate 7 and the two opposite edges of the upper bearing plate 5, and the spring-back directions of the two groups of spring-back mechanisms are respectively parallel to the longitudinal bridge direction of the bridge;
[0031] A load-bearing assembly, the load-bearing assembly includes a lower bearing plate 11 arranged at the bottom of the intermediate steel lining plate 7, the lower bearing plate 11 is fixedly connected to the bridge pier, and a deflection mechanism is arranged between the lower bearing plate 11 and the intermediate steel lining plate 7.
[0032] The main function of the upper bearing plate 5 is to support the buffer assembly, and at the same time enable the reset assembly to drive the upper steel plate 1 to move and reset by driving the upper bearing plate 5; the main functions of the polymer material buffer mechanism and the spring buffer mechanism are to provide a certain vertical stiffness and at the same time avoid the impact force generated between the girder and the upper steel plate 1 during beam dropping from causing harm to the bearing and the girder; the main function of the two groups of spring-back mechanisms is to generate spring-back in opposite directions with the intermediate steel lining plate 7 as the reaction seat. When the girder is separated from the upper steel plate 1, the upper bearing plate 5 can drive the upper steel plate 1 to return to the initial position, realizing the self-resetting function of the bearing, so as to meet the horizontal misalignment conditions that may occur when the bridge is opened and closed; the main function of the deflection mechanism is to enable the intermediate steel lining plate 7 to deflect to meet the requirements of the bridge corner. Overall, on the basis of meeting the basic requirements of the bridge such as vertical load-bearing, corner, and displacement, the steel bearing of the present utility model can buffer the impact force generated between the girder and the steel bearing during the vertical lifting of the opening bridge, and meet the horizontal misalignment during the vertical lifting of the opening bridge, meeting the use requirements of the vertically lifting and opening bridge.
[0033] For a further optimized solution, the polymer material buffer mechanism includes a pelvic cavity opened at the top of the upper support plate 5. A pressure-bearing damping rubber plate 4 is arranged in the pelvic cavity. The top of the pressure-bearing damping rubber plate 4 abuts against an upper lining plate 2. The upper lining plate 2 is slidably connected in the pelvic cavity. The bottom of the upper steel plate 1 is fixedly connected to the top of the upper lining plate 2.
[0034] As Figure 1 shown, when the beam drops, the impact force generated by the contact between the beam body and the upper steel plate 1 is transmitted to the pressure-bearing damping rubber plate 4 through the upper lining plate 2. The main function of the pressure-bearing damping rubber plate 4 is to buffer the impact force and avoid impacting the intermediate steel lining plate 7 and the structure below it.
[0035] For a further optimized solution, a sealing ring 3 is sleeved between the side wall of the pressure-bearing damping rubber plate 4 and the inner wall of the pelvic cavity.
[0036] The main function of the sealing ring 3 is to prevent the pressure-bearing damping rubber plate 4 from being extruded from the gap between the upper lining plate 2 and the inner wall of the pelvic cavity under high pressure, thereby avoiding damage to the pressure-bearing damping rubber plate 4 along the periphery.
[0037] For a further optimized solution, the spring buffer mechanism includes two groups of leaf spring groups 12 fixedly connected to the top of the upper support plate 5. The two leaf spring groups 12 are symmetrically arranged at two opposite side parts of the upper support plate 5. The bottom of the upper steel plate 1 abuts against the top of the leaf spring groups 12.
[0038] As Figure 1 and Figure 2 shown, the leaf spring group 12 is formed by stacking three leaf springs. The leaf spring group 12 is arranged in an arch shape. Its two ends are respectively fastened to two opposite side parts of the upper support plate 5 by bolts. The top of the leaf spring group 12 abuts against the bottom of the upper steel plate 1, used to provide a certain vertical stiffness and further buffer the impact force generated when the beam drops.
[0039] For a further optimized solution, the resilience mechanism includes a polyurethane spring 13. The two ends of the polyurethane spring 13 respectively abut against the outer wall of the intermediate steel lining plate 7 and the side part of the upper support plate 5. The telescopic direction of the polyurethane spring 13 is arranged parallel to the longitudinal bridge direction of the bridge.
[0040] For a further optimized solution, one end of a limiting rod 16 is horizontally and fixedly connected to each of the two opposite side walls of the intermediate steel lining plate 7. The bottom side part of the upper support plate 5 is vertically fixedly connected with a side plate 5-1. The other end of the limiting rod 16 slidably penetrates through the side plate 5-1. The polyurethane spring 13 is slidably sleeved on the limiting rod 16, and the two ends of the polyurethane spring 13 respectively abut against the side wall of the intermediate steel lining plate 7 and the side wall of the side plate 5-1. The main function of the limiting rod 16 is to limit the telescopic direction of the polyurethane spring 13.
[0041] For a further optimized solution, one end of the limiting rod 16 is fixedly connected to the side wall of the middle steel liner 7 by means of threads.
[0042] As Figure 1 and Figure 2 shown, along the longitudinal direction of the bridge, two sets of polyurethane springs 13 are respectively arranged on two opposite side walls of the middle steel liner 7, with a total of four sets. When the bridge is opened, the beam body is separated from the upper steel plate 1, so that the upper bearing plate 5 no longer bears the horizontal load. The four sets of polyurethane springs 13 rebound with the middle steel liner 7 as the reaction seat, so that the upper bearing plate 5 returns to the initial position under the action of the same-sized and opposite-direction elastic forces on both sides, realizing the self-resetting function of the bearing, thus meeting the requirements of the horizontal dislocation conditions that may occur when the bridge is opened and closed, enabling the beam body to have good contact with the steel bearing every time the beam is lowered, and enabling the steel bearing to provide reliable support.
[0043] For a further optimized solution, an upper planar slide plate 6 is abutted between the bottom of the upper bearing plate 5 and the top of the middle steel liner 7.
[0044] As Figure 1 shown, the main function of the upper planar slide plate 6 is to reduce the sliding resistance between the upper bearing plate 5 and the middle steel liner 7.
[0045] For a further optimized solution, the deflection mechanism includes a spherical crown liner 9 slidably connected to the top of the lower bearing plate 11 and a limiting groove 15 fixedly connected to the top of the spherical crown liner 9. Both the spherical crown liner 9 and the middle steel liner 7 are located within the limiting groove 15. A spherical concave groove is provided at the bottom of the middle steel liner 7, and the spherical concave groove is adapted to the top arc surface of the spherical crown liner 9.
[0046] As Figure 1 shown, the main function of the limiting groove 15 is to limit the movement range of the middle steel liner 7, so that the middle steel liner 7 can only perform a small-range horizontal movement and angular deflection within the limiting groove 15.
[0047] For a further optimized solution, a spherical slide plate 8 is abutted between the spherical crown liner 9 and the spherical concave groove, and a lower planar slide plate 10 is abutted between the spherical crown liner 9 and the lower bearing plate 11.
[0048] As Figure 1 shown, the main function of the spherical slide plate 8 is to reduce the sliding resistance when the middle steel liner 7 deflects along the top of the spherical crown liner 9, and the main function of the lower planar slide plate 10 is to reduce the resistance when the spherical crown liner 9 slides on the lower bearing plate 11.
[0049] For a further optimized solution, a plurality of anchoring devices 14 are fixedly connected to the bottom of the lower bearing plate 11. The main function of the plurality of anchoring devices 14 is to anchor the lower bearing plate 11 on the pier, so as to achieve the effect of fixing the steel bearing of the present invention on the pier.
[0050] A vertical take-off and landing opening bridge includes the steel bearing adapted to the vertical take-off and landing opening bridge as described above. Such a vertical take-off and landing opening bridge is provided with a steel bearing adapted to the vertical take-off and landing opening bridge on the pier. Thus, when the beam body rises and opens, the upper bearing plate 5 can automatically return to the initial position under the action of the polyurethane spring 13, meeting the horizontal misalignment conditions that may occur when the bridge opens and closes. At the same time, when the beam is lowered, the impact force generated when the beam body closes can be buffered by the pressure-bearing damping rubber plate 4 and the steel plate spring group 12, avoiding the possible hazards to the bearing and the beam body caused by the impact force.
[0051] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.
[0052] The embodiments described above are only for describing the preferred mode of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solution of the present invention shall fall within the protection scope determined by the claims of the present invention.
