> Pot-type rubber bearings
are made of elastic rubber blocks in a semi-enclosed steel pelvis, which have fluid properties under three-way stress. Characteristics, to realize the rolling of the upper part of the bridge, and at the same time rely on the low friction coefficient between the plate on the base steel plate and the stainless steel plate on the upper seat plate to realize the horizontal displacement of the upper structure, so that the shear endured by the bearing is no longer completely determined by the rubber Responsible for the direct effect on the slip between the steel bottom basin and plate and stainless steel. Judging from the test data, the compressive elastic modulus of rubber when it is in a three-way binding state is /, which is nearly twice as much as the compressive elastic modulus without lateral binding. Therefore, the bearing capacity of the bearing is greatly improved and solves the problem. The plate rubber bearing has limited bearing capacity and can meet the needs of large support reaction force, large horizontal displacement and rotation angle.
> Series of basin-type rubber bearings
The products are produced and manufactured in accordance with the technical appraisal documents of the tonnage_ basin-type rubber bearings
issued by the Ministry of Railways. They are other series of bearings. It is a base guide groove type one-way movable rubber bearing product based on the application experience, research and design. And refer to the table and other company product plans. Because the bearings of the series, etc. are all guide-trough movable bearings at both ends, when used on multi-span connections, the side bending of the beam due to the temperature stress of sunlight will easily produce binding force on the guide-trough one-way movable bearings at both ends. , and the base guide groove type one-way movable bearing when the beam body bends sideways, the base guide groove can move the base steel lining plate of the support to do a small amount of roll. Can prevent lateral binding forces.
, multi-directional movement_ basin-type rubber bearing
The stainless steel plate and PTFE plate are lubricated with silicone grease to reduce friction resistance. , Longitudinal movement_ Basin-type rubber bearing adopts base guidance method, which can adapt to the needs of side bending deformation of the beam body. , Longitudinal movement_ The basin-type rubber bearing
adopts base guide, which reduces the weight and the number of steel castings compared with the trough-shaped upper bearing plate currently widely used in China. . Installing dust-proof enclosures in the series_ basin-type rubber bearing
can reduce dust intrusion and extend the service life of the product.

In recent years, with the environmental protection policy of Hebei Province The regulations are getting stricter and stricter. Some rubber factories have been ordered to shut down for rectification due to the stench that disturbs the public, and some have had their power cut off. The days of producing and polluting at the same time can no longer continue. Rubber factories have begun to carry out equipment renovations. Hengshui Railway Construction Holding Group is the leader among them.
