Description

Technical Field

[0001] This utility model relates to the field of railway bridge bearing technology, specifically a railway bridge bearing with good drainage effect. Background Technology

[0002] Railway bridge bearings are located between the bridge and the bearing pad. They reliably transfer the loads and deformations borne by the superstructure of the bridge to the substructure, and are an important force transmission device for bridges.

[0003] A bridge bearing, authorized by announcement number CN222227046, includes a steel plate on the bearing. A stainless steel plate is fixedly installed at the top of the steel plate inside the bearing, and a wear-resistant plate is fixedly installed at the bottom of the stainless steel plate. A polytetrafluoroethylene (PTFE) gasket is fixedly installed at the bottom of the wear-resistant plate. By fixing the stainless steel plate at the top of the steel plate inside the bearing, the weight of the steel plate on the bearing can be increased. Then, the wear-resistant plate reduces the friction between the PTFE gasket and the steel plate on the bearing, thereby reducing the damage to the PTFE gasket and ensuring its normal operation. Furthermore, the combined use of the PTFE gasket and the spherical crown buffer pad enables the bridge bearing to have good buffering capacity and increases its seismic resistance. Currently, the spherical crown in the middle of the railway bridge bearing lacks fixation, resulting in misalignment. At the same time, the bottom of the entire bridge bearing is sealed, leading to water accumulation at the bottom of the bearing.

[0004] To address the aforementioned issues, a railway bridge bearing with good drainage performance is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a railway bridge bearing with good drainage effect, which solves the problem that the spherical crown in the middle of the current railway bridge bearing lacks fixation and has misalignment, and that the bottom of the entire bridge bearing is sealed, resulting in water accumulation at the bottom of the bearing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a railway bridge support with good drainage effect, including a lower support, a balancing component movably engaged at the upper end of the lower support, an upper support slidably embedded at the upper end of the balancing component, auxiliary screws sleeved at the four corners of the lower and upper supports, the lower support including a frame plate, right-angle brackets screwed at the four corners of the frame plate, a middle frame screwed at the center of the frame plate, a balancing component including a dome block fitted to the upper end of the middle frame, a tie rod rotatably connected to the outside of the dome block, eight sets of tie rods, a slider rotatably mounted at one end of each tie rod, the slider slidably mounted inside the right-angle bracket, and an upper support including an upper support plate sleeved on the upper end of the dome block, a protective plate being provided on one side of the upper support plate.

[0007] Preferably, the right-angle frame has sliding grooves on its two right-angle sides, drainage holes are provided at the right-angle junctions of the right-angle frame, and holes are provided on the frame plate corresponding to the drainage holes.

[0008] Preferably, the right-angle frame has a side hole at one end.

[0009] Preferably, the two sides of the central frame are screwed together with side plates, and the side plates are screwed together with the frame plate.

[0010] Preferably, a plug rod is provided in the middle of the frame.

[0011] Preferably, the balancing component further includes a transition block fixedly disposed on the outside of the dome block, the transition block being rotatably connected to the pull rod.

[0012] Preferably, the slider is slidably disposed inside the groove, and there are eight sets of sliders, the eight sets of sliders being completely symmetrical about the central axis of the frame plate, and the frame plate being square.

[0013] Preferably, the lower middle part of the upper support plate is provided with a dome groove corresponding to the dome block.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a railway bridge bearing with good drainage effect. By setting the lower bearing, the frame plate is set as a hollow structure, and the middle frame is connected to the hollow part of the frame plate. The frame plate and the middle frame are set together at the bottom, which facilitates drainage at the bottom of the bearing and prevents water accumulation, thus solving the problem of water accumulation at the bottom of current railway bridge bearings.

[0015] 2. This utility model provides a railway bridge bearing with good drainage effect. Through the setting of the balancing component, the spherical dome block movably connected to the upper end of the central frame is pulled around by eight sets of tie rods. The tie rods are slidably set in the right-angle frame through sliders. The eight sets of tie rods provide tension in eight directions for the spherical dome block, forming a symmetrical and balanced prestressed field, which is equivalent to pre-tensioning the spherical dome block, thereby greatly improving its resistance to external loads and improving the stability of the spherical dome block from the side. The central frame and the spherical dome block are inserted vertically to provide lower end support for the spherical dome block. The upper support plate is sleeved with the spherical dome block to prevent the bearing from eccentric deformation. The protective plate is set at the outer end of the right-angle frame, which can realize the sleeve protection and anti-displacement functions, and solves the problem of the lack of fixation of the central spherical crown of the current railway bridge bearing, which causes misalignment.
