Description

Technical Field

[0001] The invention relates to the technical field of bridge rubber bearings, and in particular to a bridge basin-type rubber bearing that is easy to maintain. Background Art

[0002] Bridge rubber bearings are widely used in bridge construction and other fields because they have good vertical stiffness, good elasticity and seismic isolation effect, and can reduce the impact of live loads and seismic forces on bridges.

[0003] However, the existing bridge rubber bearings still have the following problems: ① Due to the large friction between the wear-resistant plate and the supporting steel plate, the wear-resistant plate will be severely worn out after a period of use, and the wear-resistant plate needs to be replaced frequently; ② Since the two ends of the bearing are fixed to the mounting surface by bolts, and for reinforcement, it is also necessary to fix it by pouring cement. When replacing the bearing, the mounting surface needs to be destroyed to remove the bearing, which is inconvenient.

[0004] Based on this, the present invention designs a bridge basin-type rubber bearing that is easy to maintain to solve the above problems. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a bridge basin-type rubber bearing that is easy to maintain.

[0008] The top of the support body is detachably connected to the upper connecting steel plate through a quick-connect assembly, and the bottom of the support body is detachably connected to the lower connecting steel plate through a quick-connect assembly;

[0009] The quick-connect assembly includes a limit slide groove and a limit slider; the top of the support body and the bottom of the support body are fixedly connected with a plurality of limit sliders, the upper surface of the lower connecting steel plate and the lower surface of the upper connecting steel plate are provided with a plurality of limit slide grooves that cooperate with the limit sliders, and the limit sliders are slidably connected in the limit slide grooves;

[0010] A lubricating oil circulation assembly is installed on one side of the basin-type support; the lubricating oil circulation assembly includes a return pipe, a control valve, a liquid outlet pipe, a liquid pump, a liquid inlet pipe and a liquid collecting box; a vortex groove is provided on the bottom surface of the wear-resistant plate, and baffles are fixedly connected to the two side walls of the wear-resistant plate respectively; the upper end of the supporting steel plate is fixedly connected to the liquid collecting box, the lower end of the wear-resistant plate is arranged inside the liquid collecting box, and the lower surface of the wear-resistant plate is in contact with the upper surface of the liquid collecting box, and a channel connected to the vortex groove is provided on the wear-resistant plate, and the other end of the channel is connected to the liquid pump through the liquid inlet pipe.

[0011] Furthermore, the lower surface of the supporting steel plate contacts the upper surface of the pressure ring.

[0012] Furthermore, the opening direction of the limiting sliding groove and the limiting sliding block is perpendicular to the movement direction of the support body.

[0013] Furthermore, the support body is fixedly connected to the upper connecting steel plate and the lower connecting steel plate by reinforcing bolts. The lower connecting steel plate, the upper connecting steel plate and each limiting sliding block are provided with through holes for the reinforcing bolts to pass through, and the other end of the reinforcing bolt is threadedly connected with a locking nut.

[0014] Furthermore, the width of the liquid collecting box is greater than the diameter of the supporting steel plate.

[0015] Furthermore, the baffle plate covers the upper end of the liquid collecting box, and the baffle plate is movably connected to the liquid collecting box through a sliding groove arranged at the edge of the liquid collecting box, and the baffle plate is in close contact with the sliding groove.

[0016] Furthermore, the width of the baffle is greater than the width of the liquid collecting box, and the baffle always covers the liquid collecting box during the movement.

[0019] Beneficial Effects

[0020] When the support body needs to be replaced, the support body is lifted to a set position by an external hydraulic lifting structure, and then the reinforcing bolts are removed, and then the support body is pulled to separate the limit slider from the limit slide groove, that is, the limit sliders at the upper and lower ends of the support body are separated from the lower connecting steel plate and the upper connecting steel plate, so that the support body can be disassembled. The process of replacing the support body in this application does not require the removal of the lower connecting steel plate and the upper connecting steel plate, and will not damage the installation surface. The disassembly is convenient, and the support body can be quickly replaced, which can be well applied to bridge construction and other fields.

[0021] The present invention sets a baffle sealing cover on the liquid collecting box, which can prevent mosquitoes and dust from entering the liquid collecting box and contaminating the lubricating oil; on the other hand, it can prevent oil from leaking out, polluting the environment and causing oil loss; adding a sliding groove can also guide the direction of the baffle and the wear-resistant plate, thereby realizing the control function of the unidirectional (forward and backward) movement of the support body;

[0022] The lubricating oil of the present invention enters the channel through the liquid inlet pipe and then enters the vortex groove. Since the vortex groove adopts a vortex structure, the lubricating oil can fill the entire vortex groove, avoiding the situation where only part of the wear-resistant plate has the lubricating oil, resulting in large loss of the wear-resistant plate. The lubricating oil fills the space between the wear-resistant plate and the supporting steel plate to play a lubricating role, which can reduce the wear of the wear-resistant plate, increase the service life of the wear-resistant plate, and avoid frequent replacement of the wear-resistant plate. The oil flows back to the liquid pump through the liquid collection box via the reflux pipe, thereby realizing the circulation of the oil. The liquid pump can be started regularly to circulate the oil to keep the lubrication of the wear-resistant plate, thereby further increasing the service life of the wear-resistant plate.
