Description

Bidirectional moving basin type support

Technical Field

The utility model relates to a basin formula support field especially relates to a two-way movement basin formula support.

Background

The engineering of expanding and upgrading the channel of the north river (from the black stone of the Qujiang to the river mouth of three rivers) flies from the gorge junction engineering of two or three lines of ship locks, the flood-blocking access doors at the head of the upper and lower locks open and close the basin-type support supports used by the trolley beams, and because the span of the trolley beams of the hoist and close the machine is large and the load is large, when the environmental temperature changes in use, the longitudinal and transverse expansion and contraction variation of the trolley beams is large, and in addition, the trolley beams can bend a small amount under the action of large load, so that the pivot points are warped, and the two conditions can cause the whole system to generate multidirectional additional stress.

The novel bridge support commonly used at present is a basin-type rubber support and comprises an upper seat plate, a sealing ring, a rubber plate, a bottom basin, foundation bolts, a dust cover and the like. For the existing basin-type rubber support, because the support has a large supporting load and is a large structural member, the used materials are more, the plane is large, the factors such as deformation are increased, and the manufacturing difficulty is increased; the support has more layers, more round parts, relatively lower material utilization rate and larger material consumption; the support seat material relates to various materials such as stainless steel, carbon steel, cast steel, low-friction plastic alloy, rubber, copper seal and the like, the number of products is small, the purchasing difficulty is high, and the material price is high; the support has more components and large manufacturing and processing amount; the production of the blanks of the cast steel base and the rubber pad of the product requires the production of a mold, and the processing also requires the production of auxiliary tools, so that more auxiliary manufacturing cost is required; the polytetrafluoroethylene plate is lubricated by silicone grease when in use, but the oil can not be added in the use process; the span of the trolley beam in the project is large, the self weight is heavy, and the difficulty of later maintenance and replacement is large.

According to the engineering design requirement, a bidirectional moving basin-type support with better performance is specially designed for a new support device.

Detailed Description

Referring to fig. 1, the utility model relates to a two-way removal benzvalene form support, it includes bedplate 1 and base 2, go up bedplate 1 and base 2 all with roof beam bottom plate fixed connection, from supreme lower slip surface course, rubber cushion layer 3, middle steel bed course 4, the upper sliding surface course of having set gradually down between last bedplate 1 and the base 2, slip surface course and upper sliding surface course all are provided with the sliding plate 5 who corresponds with it down. The upper seat plate 1 and the base 2 are installed in a centering way.

Specifically, the rubber pad 3 can absorb shock and accommodate a certain amount of fulcrum rotation. The bearing capacity and the impact resistance of the support are improved. The bearing capacity of the basin-type support is not less than 8000kN, the height is 175mm, the displacement along the bridge direction is +/-100 mm, the transverse displacement is +/-40 mm, the use environment temperature is minus 20-minus 40 ℃, the friction coefficient of an upper sliding surface layer and a lower sliding surface layer of the support is 0.1-0.15, and the service life of the basin-type support is longer than 50 years.
