Description

A kind of improved overhead crane with hook

Technical field

The utility model relates to the hoisting crane field, concretely, relates to a kind of improved overhead crane with hook.

Background technology

To be a kind of crane span structure be bearing in crane span structure type hoisting crane on the ground rail by two side legs and grade beam to hoisting crane.Be to make the weight that hangs on crane hook or other load-engaging device realize the weight-lifting equipment of vertical lift and parallel motion in the space.It is widely used in the warehouse of open works such as industrial and mineral, harbour, railway, the loader and porter in stock ground do, and its load-engaging device is suspension hook, grab bucket or magnetic chuck (lifting electromagnet), can use wherein two kinds or three kinds simultaneously.1, the classification of hoisting crane: (1), by the pattern branch of metal structure (mechanism's quantity): 1), become to be divided into two kinds of real abdomen box-shaped beam type and truss-likes by the metal structural group; 2), can be divided into two kinds of twin beams, single girders by the main beam structure pattern, the pattern of portal-framed structure has two cantilevers, single-cantilever and does not have three kinds on cantilever.3), can be divided into single crab structure, double trolley structure and many vehicle structures according to lifting mechanism quantity.4), by the supporting leg number can be divided into transfer crane and semi-goliath crane (code name: MB) (2), press features such as crane girder pattern, load-engaging device, dolly configuration, 1), box pair of girder is divided into following kind:: suspension hook gate-type, code name MG, double trolley suspension hook gate-type ME, grab bucket gate-type MZ, electromagnetism gate-type MC, grab bucket suspension hook gate-type MN, grab bucket electromagnetism gate-type MP, Three-purpose door formula MS.2), box single girder: suspension hook gate-type, code name MDG, double trolley suspension hook gate-type MDE, grab bucket gate-type MDZ, electromagnetism gate-type MDC, grab bucket suspension hook gate-type MDN, grab bucket electromagnetism gate-type MDP, Three-purpose door formula MDS.

The cart wheel of hoisting crane produces very big pressure to track, generally can not realize little tonnage large span.

Summary of the invention

In order to overcome above-mentioned deficiency, this practical purpose is to provide a kind of improved overhead crane with hook, and it can effectively reduce the pressure of wheel to guide rail, realizes adopting little tonnage large span.

The utility model is made up of railing, vehicle frame, crane span structure, girder, dolly conduction rack, girder guide rail, end carriage, column, column track, coaster, cable, trundle, retarder, crane span structure wheel; Crane span structure is by girder, the railing in the end carriage and the two girders outside is formed, the two ends of two girders are placed on the two ends of two butt beams, girder is connected with screw with end carriage, one side bottom of crane span structure is equipped with the crane span structure wheel, the crane span structure wheel is placed on the column track of column, dolly is made up of vehicle frame, electrical motor, trundle and retarder, lay the girder guide rail on the girder, the girder guide rail is fixed by bolts on the girder, and trundle is on the girder guide rail, and the crane span structure wheel adopts two-wheel, the dolly conduction rack is connecting cable, and cable is connected with dolly by coaster.

Characteristics of the present utility model: the vehicle frame wheel adopts double wheel design, can effectively reduce the pressure of wheel to guide rail, and the main hook of dolly and auxiliary hook get hoisting capacity and be respectively 40 tons and 10 tons, adopts inclined to one side beam-and-rail design.
