Aiming at the defects in the prior art, the invention aims to provide a container shore bridge with adjustable lifting pulley spacing, which can increase the component force of a lifting steel wire rope in the horizontal direction of a lifting appliance load so as to reduce or eliminate the swing of the lifting appliance load.
In order to achieve the above purpose, the invention adopts the following technical scheme:
A container quay crane with adjustable lifting pulley spacing, comprising: the dolly track still includes: the first separation trolley, the second separation trolley and the lifting appliance load are arranged on the trolley track, the first separation trolley and the second separation trolley are respectively provided with a lifting pulley, each lifting pulley is connected with a lifting appliance end pulley through a lifting wire rope, the two lifting appliance end pulleys are connected with the lifting appliance load, and the first separation trolley and the second separation trolley are also connected with a driving mechanism.
And the driving mechanisms on the first separation trolley and the second separation trolley are connected with the operation console.
And absolute displacement sensors are arranged on the first separation trolley and the second separation trolley.
The driving mechanism is traction type driving or self-propelled driving.
The first separation trolley and the second separation trolley both comprise: the trolley comprises a trolley frame and trolley wheels arranged below the trolley frame.
In the technical scheme, the container shore bridge with the adjustable lifting pulley spacing is simple in design structure and easy to install, can generate larger horizontal component force on the load end of the lifting appliance, can effectively inhibit or even eliminate free swing motion of the load of the lifting appliance, and provides necessary precondition for the whole quick and accurate positioning and intelligent control of the lifting appliance.
Drawings
FIG. 1 is a schematic diagram of a prior art container shore bridge;
fig. 2 is a schematic structural view of the present invention.
Detailed Description
The technical scheme of the invention is further described below with reference to the accompanying drawings and examples.
Referring to fig. 2, the container shore bridge with adjustable lifting pulley spacing provided by the present invention includes: the trolley track 10 further comprises: the first separation trolley 11, the second separation trolley 12 and the lifting load 13 are arranged on the trolley track 10, lifting pulleys 14 are arranged on the first separation trolley 11 and the second separation trolley 12, each lifting pulley 14 is connected with a lifting end pulley 16 through a lifting steel wire rope 15, the two lifting end pulleys 16 are connected with the lifting load 13, and the first separation trolley 11 and the second separation trolley 12 are also connected with a driving mechanism 17.
Because the first separation trolley 11 and the second separation trolley 12 can independently or in association, the direct distance between the two separation trolleys 11 and 12 can be amplified in a certain safety range along with the different lifting heights of the lifting appliance, for example, the distance can be 5 meters to 8 meters and even 10 meters, so that a large horizontal component force can be generated at the end of the lifting appliance load 13 through the lifting wire rope 15, the free swing motion of the lifting appliance and the load can be effectively restrained or even eliminated, and the necessary premise is provided for quick and accurate positioning and intelligent control of the lifting appliance.
Preferably, the first separation trolley 11 and the second separation trolley 12 each include: a trolley frame 18, and trolley wheels 19 provided below the trolley frame 18, the trolley wheels 19 moving on the trolley track 10.
Each separation trolley 11, 12 in the large-distance separation double separation trolley is an independent running body, the direct distance between the two separation trolleys 11, 12 can greatly float, the component force of the lifting wire rope 15 in the horizontal direction of the lifting appliance load 13 is increased, and the swing of the lifting appliance load 13 is reduced or even eliminated.
Preferably, the driving mechanisms 17 on the first separation trolley 11 and the second separation trolley 12 are connected with an operation console.
In the working process, the operation control console carries out intelligent prediction, when the lifting appliance load 13 is to be lifted and the separation trolleys 11 and 12 are moved, the distance between the separation trolleys 11 and 12 is properly increased according to the lifting appliance height so as to stabilize the swing of the lifting appliance load 13. When the separation trolley 11, 12 is to be stopped, the operating console can again increase the distance between the separation trolley 11, 12 for a larger stable spreader load 13 swing, and when the separation trolley 11, 12 is to be stopped and ready to lower the spreader load 13, the separation trolley 11, 12 gradually reduces the distance and closes.
An absolute displacement sensor is mounted on each separation trolley 11, 12.
Preferably, the driving mechanism 17 is a traction type driving or a self-propelled driving.
If the device is driven by self, the two separation trolleys 11 and 12 can be separated and closed freely;
If the traction is driven, two driving rollers can be arranged to respectively control a separation trolley, and the system is controlled according to the requirement.
The system for operating the console can be provided with an intervention mechanism for controlling the separation and the closing of the two separation trolleys 11 and 12 by manual intervention, and is intelligent and automatic control at ordinary times.
One of the system can be a main trolley, and the other system is a motorized auxiliary trolley. The motion of the two trolleys can be synchronous and same-direction motion, the auxiliary trolley moves separately from the main trolley, and the auxiliary trolley moves close to the main trolley. Different occasions needing different motion modes are called, so that the quick, reliable and accurate positioning of the lifting appliance is realized, and the production efficiency is improved.
When lifting the lifting appliance from the cabin, a separation height position can be set, and when the lifting appliance is higher than the separation height position, the auxiliary trolley can perform separation movement to prevent the lifting wire rope 15 from touching the cabin wall and the container.
When the lifting appliance is lowered below a separation height, in order to prevent the lifting steel wire rope 15 from touching the cabin wall and the container, the auxiliary trolley is quickly closed up to the main trolley, so that the lowering space of the lifting steel wire rope 15 is reduced.
When the distance between the auxiliary trolley and the main trolley is greater than the distance between the auxiliary trolley and the main trolley, the auxiliary trolley can automatically separate the auxiliary trolley by a certain distance.
The system considers the main trolley position and the auxiliary trolley position to accurately calculate the accurate position of the lifting appliance in the horizontal direction.
Because of the problem of the included angle of the lifting wire rope 15, the same lifting load is reflected on the load of the lifting wire rope 15, and the real load value is recalculated through the relative position and the height of the separation trolley.
It will be appreciated by persons skilled in the art that the above embodiments are provided for illustration only and not for limitation of the invention, and that variations and modifications of the above described embodiments are intended to fall within the scope of the claims of the invention as long as they fall within the true spirit of the invention.
