Description

A reversible thread screw-in slope adjuster

technical field

The invention belongs to the technical field of bridge prefabricated T-beam construction equipment, and more specifically relates to a reversible thread screw-in slope regulator.

Background technique

Prefabricated T-beams are widely used in the construction of various bridges due to their advantages of standardization, factoryization, and centralized production.

However, when prefabricated T-beams are installed, often due to the presence of a certain longitudinal slope of the bridge, the rubber bearings in contact with the prefabricated T-beams are in a horizontal state, so that the T-beams and rubber bearings form a certain angle, resulting in stress on the T-beams and rubber pedestals. The concentrated phenomenon causes damage to the T-beam and shearing of the rubber bearing, which not only greatly reduces the service life of the rubber bearing, but also poses hidden dangers to the safe operation of the bridge; in view of this problem, the slope regulator is mainly used in the project to adjust The slope of the prefabricated T beam at the contact position with the rubber bearing makes the prefabricated T beam contact with the rubber bearing during installation. At present, most slope regulators in engineering are single-hinged, and they need to be adjusted at a very uncomfortable low position of the human body. The precision is low, and the operation is extremely inconvenient. Because of the above reasons, it is convenient and trouble-free for construction personnel to have a map, which often fails to meet the adjustment requirements and accuracy, resulting in a serious impact on the construction quality. The few slope regulators that can be automatically adjusted are also single-hinge. The rotation center of the single-hinge slope regulator is not at one end of the top plate of the slope regulator, and can only meet a certain longitudinal slope. If it is greater than this value, there will be a wrong platform. It cannot be adjusted precisely.
