Description

Rubber roll built-in elastic ring hoop for sleeving positioning pile at wharf

Technical Field

The utility model relates to a port and pier's attached mooring protection equipment's institutional advancement technique is applied to floating wharf boat and is connected with the spud pile, and especially the pier is used for cup jointing the built-in rubber roll elastic ring staple bolt of spud pile.

Background

In the prior art, a pontoon is a rectangular flat-bottomed boat without a power device, is usually fixed on the shore, is only used as a pontoon initially, is used for loading and unloading goods or pedestrians, and is also used for business, entertainment, water office work and the like with the development of the times.

In the pontoon, which was basically positioned by a chain in the past, a spud-type pontoon now appears. The guide pile type structure of the steel pipe pile is generally selected for the positioning pile, and a single pontoon mode is adopted for a pontoon. The mooring mode can be used for performing wharf operation at any time, and the displacement of the wharf boat is small.

The pontoon is mostly used as a docking platform for loading and unloading ships, cargo transfer or transverse ferry, and the like. Because there is typically no power plant, a tug boat or other external force assistance is required to move. A wharf boat specially used for cargo transfer can be provided with a hoisting boom to hoist cargoes from a cargo ship which cannot lean against the bank and transfer the cargoes to the wharf.

At present, floating pontoon wharfs are mostly adopted for berthing the official working boats in river basin, and the floating pontoon wharf has the characteristics of good adaptability to water level change, low manufacturing cost, quick construction and flexible arrangement. The floating pontoon wharf is moored generally by means of anchor chains, anchors, strut systems or positioning piles. Under the limited circumstances of waters condition, more adoption guide pile combines the fixed mode of steel staple bolt to reduce waters usable floor area, the guide pile sets up in aquatic, sets up the steel staple bolt on the wharf boat, can effectively retrain the plane removal of wharf boat, simultaneously, allows the wharf boat freely to go up and down along with the water level change again. However, when the pontoon rises and falls along with the change of water level, the positioning pile and the steel anchor ear can generate severe collision friction due to rigid contact, so that the anticorrosive coating of the steel pile is damaged and peeled off, the pile body is corroded, and the service life of the steel pile is shortened. Increasing the cost of post-maintenance. The rust produced is not compatible with the surrounding ecological environment. And the friction generates larger noise, which affects the surrounding environment.

SUMMERY OF THE UTILITY MODEL

The purpose of the utility model is realized by the following technical measures: a rubber roll built-in elastic ring hoop for a wharf to sleeve a positioning pile comprises a steel hoop and a PU roller, wherein the steel hoop and the PU roller are sleeved on the positioning pile; the steel anchor ear is of a square annular structure, an anchor ring is fixed on the inner wall of the steel anchor ear, and the anchor ring is connected with two ends of the PU roller through anchor chains.

In particular, the shaft part of the PU roller is provided with a through hole, the anchor chain is connected through the through hole, or the shaft rod is connected in the through hole in a penetrating way, and the anchor chain is connected at the outer end of the shaft rod.

Particularly, two ends of the middle shaft part of the PU roller are respectively provided with a hinge structure which is connected with the anchor chain through a bearing structure.

Particularly, each group of PU wheel rollers is fixedly connected by an upper group of anchor chains and a lower group of anchor chains, and two ends of the two groups of anchor chains are correspondingly tied on two pairs of anchor rings arranged on the upper part and the lower part of the inner wall of the steel anchor ear respectively.

Particularly, a group of PU wheel rollers are respectively arranged on four inner walls of the steel hoop.

Particularly, the outer diameter of the PU roller is 0.75-0.95 of the minimum clearance under the condition that the inner wall of the steel hoop and the outer wall of the positioning pile are coaxial.

In particular, the outer wall of the PU roller is provided with a convex edge or a straight groove.

In particular, the outer walls of the steel anchor ear and the PU roller are provided with polyurethane elastic protective layers.

In particular, at least two independent PU wheel rollers form a group and are connected with the same anchor chain together.

In particular, the outer wall of the positioning pile (5) is coated by glass fiber reinforced plastic.

The utility model discloses an advantage and effect: the PU wheel roller can absorb the relative motion load of the pontoon and the positioning pile, and the friction between the steel anchor ear and the positioning pile is obviously reduced, so that the glass fiber reinforced plastic coating of the positioning pile is effectively protected, and the maintenance cost is reduced; therefore, the designed pile diameter of the positioning pile can be properly reduced, and the manufacturing cost is reduced; the pontoon can float up and down along with the water level, and can keep stable in the wave, ensures the safety of the pontoon. Through PU wheel roller and spud cup joint the cooperation, when the steel staple bolt height changed along with the water level, floated about for the spud, can effectual realization pontoon location.
