From deepwater regions build a seat height stake beam and slab type Wharf Platform, be connected by several access bridges with land.When Wharf Platform is built,
Need first by more engineering sunk piles to river bottom or seabed, in engineering pile upper end, prefabricated diameter is more than the concrete in engineering pile stake footpath
Pile cover, and on pile cover top between it is prefabricated form grid-shaped crisscross connection multiple row longeron and multirow crossbeam, in harbour
Outside large-scale floating crane is pre- by polylith by the prefabricated wharf slab handling being placed on the square barge in its one side to pier
The longitudinally adjacent side of wharf slab processed is laid on the adjacent longeron of two row with connecting successively.So repeat to lay precast beam by column
Plate, until completing the laying of large pier precast beam.
Conventional harbour width is in 30-40m or so, including fixed width degree harbour and the fixed width degree code of harbour lateral dimension change
Head, harbour of the width more than 40m are referred to as ultra-wide harbour.Ultra-wide harbour needs to carry out handling with the longer large-scale floating crane of arm in building
Operation, the manufacture of one side large-scale floating crane and construction cost are expensive, on the other hand by tidal level and wind in its running
Wave has a great influence, up and down balance system poor-performing.
Therefore, it is necessary to which a kind of new technical scheme is to solve the above problems.
Utility model content
Purpose of utility model：In order to solve the problems of prior art, the utility model provides a kind of structure letter
List, layout designs are reasonable, and security performance is high, improves operating efficiency, reduces operating cost, effectively improves the harbour face of working area
Plate installs special gantry crane.
Technical scheme：To reach above-mentioned purpose, the utility model can adopt the following technical scheme that：Wharf slab installation is special
Gantry crane, specially single-motor double suspension centre structure, by door frame, lifting mechanism, traveling mechanism of the larger traveller, cucurbit slew gear with
And electrical equipment composition；The door frame includes lifting machine framework, supporting leg and sill composition；The traveling mechanism of the larger traveller is single
The wheel group structure of side three, wherein stress side are provided with the first wheel group and the second wheel group with bogie frame combined support, opposite side
Provided with the 3rd wheel group；The bogie frame group is provided with " three-in-one " decelerator；The cucurbit slew gear is located at crane
Side, including electric block, slewing equipment and cucurbit that left rotation and right rotation angle is 20 ° run I-steel；The electric block
I-steel is run by slewing equipment and cucurbit and is connected to crane side.
Further, the lifting mechanism include variable-frequency motor, shaft coupling, compensator, brake, decelerator, reel,
Steel wire rope, fixed pulley group and suspension hook group.
Beneficial effect：Wharf slab disclosed in the utility model installs special gantry crane, specially single-motor double
Suspension centre structure, ensure two suspension centre synchronization liftings, improve it and run balance and stability performance, traveling mechanism of the larger traveller is unilateral three cars in addition
Wheel group structure, reduces manufacturing cost, the setting of cucurbit slew gear, effectively increases the working area of crane.This practicality
New structure is simple, and layout designs are reasonable, and security performance is high, improve operation balance and stability performance and has widened working area,
Not only increase operating efficiency and substantially reduce operation and maintenance cost that wharf slab installs special gantry crane, it is practical
Value is notable.
