Description

Portal frame movable container crane

Technical Field

The utility model relates to a light small-size hoisting equipment technical field, in particular to portal frame mobile container crane.

Background

A crane is commonly known as a crane, and refers to a multi-action hoisting machine for vertically lifting and horizontally carrying heavy objects within a certain range, which is also called as a crown block, a gantry crane and a crane, and can be divided into a fixed crane and a movable crane. The mobile crane is a crane which can freely move along a track or a non-track. Most of the existing mobile cranes are single-arm or rail type, vehicle-mounted type and fixed type cranes, the use field required by the cranes is large, and the mobility of the cranes is not strong.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model discloses a portal frame mobile container crane, the technical scheme of the utility model is implemented like this:

the utility model provides a portal frame portable container crane, includes frame assembly, crossbeam assembly, lifting beam assembly, bottom end rail, wheel system, steering cylinder, hydraulic pressure pipeline, hydraulic control system and driving system, two the frame assembly is installed the top end rail assembly downside both ends constitute crane frame main part, lifting beam assembly installs two between the frame assembly, two the bottom end rail is all installed to frame assembly lower extreme, two the wheel system is installed respectively two on the bottom end rail, wheel system with steering cylinder connects, and two are many steering cylinder passes through hydraulic pressure pipe connection, one frame assembly lower extreme side-mounting have hydraulic control system with driving system, hydraulic control system can control steering cylinder's flexible state, driving system is portal frame portable container crane's steering cylinder's steering state, The walking and lifting of the beam assembly provide power.

Preferably, the wheel system includes wheel, wheel support and steering mechanism, the wheel support install on the wheel, the wheel support with steering mechanism connects, steering mechanism installs on the frame assembly, steering cylinder's telescopic link with wheel support fixed connection.

Preferably, the upper cross beam assembly is connected with the frame assembly through bolts.

By implementing the technical scheme of the utility model, the technical problems of large use area and weak mobility required by the existing mobile crane in the prior art can be solved; implement the technical scheme of the utility model, realize the walking function through wheel system, through the steering angle who operates hydraulic control system control wheel system, every wheel all can be at 0-110 within range internal rotation, the steering cylinder of both sides passes through hydraulic line and connects in order to realize the joint action, thereby such wheel system can turn to the wide-angle and has realized that the container crane need not to go on around under the condition that the complete machine turned to, walk about, greatly improved the flexible flexibility of equipment. When more than two groups of independent cranes are used in combination, the distance can be adjusted according to the size of the container, and the crane is suitable for containers with different sizes; the lifting is convenient and fast, the container can be stacked up, and the stacking space is saved.
