Description
Technical field
The present invention relates to a kind of quayside container crane operation, container spreader height real-time display guidance device of being used for.
Background technology
Along with container ship to large scale development, load 3000TEU (standard container) by single ship in 10 years and develop into present single ship and load 8500TEU, 40 meters of the also corresponding increases of the beam.Recently, the freight container traffic cargo ship of 10000TEU also constantly joins the troop of freight container sea-freight.Unload for adapting to big ship, the lifting altitude of quayside container crane suspender is increased to 45 meters by 35 meters.The carrying capacity of boats and ships is big more, and to the just raising all the more of requirement of handling speed, because the shipping boats and ships are to be purpose with the transportation, the increase in turn-around time can cause reducing of effective haulage time, has reduced transport benefits, and has increased cost.Therefore, there is urgent demand at the harbour for improving handling speed, and high efficiency loading and unloading mean and reduced expense, have improved the competitive power at harbour.
The loading and unloading operation of freight container marine vessel is finished by shore container crane at present, and shore container crane is the handling equipment that carry out container handling operation in the wharf apron, is also referred to as bank bridge container hoisting crane, is called for short bridge crane.In the container handling operation, bridge crane driver freight space is directly over suspender, must be in about more than 40 meters high-altitude, whether the freight container that observation is hung in below the suspender drops on above the delivery truck, especially last 1～2 meter of the case that falls, be the comparison difficulty, the driver can only be by range estimation and experience to the judgement of box height.Variation along with the suspender lifting altitude, the driver judges that on long sight distance the height of casing can be difficult more, handling speed and crash-avoidance are difficult to satisfactory to both parties, the result who pursues handling efficiency can make the driver of operation bridge crane accelerate the rising or falling speed of bridge crane suspender, spirit has absent-mindedness that the casing collision case will take place slightly, the safety that has a strong impact on freight container and goods and deliver truck; Simultaneously, driver's degree of fatigue is also higher, and then also can have influence on the order of accuarcy of operation.
Existing quayside container crane equipment utilizes rope capacity to measure the spreader height of bridge crane, and its form with numeral is presented in the bridge crane driving compartment.There are two problems: the firstth, the bridge crane driver is when operation, concentrate one's energy to watch to following, eyes are in the long sight distance observation state, if racket head is observed numeric display again, eyes are difficult to adjust in the short time myopia apart from observation state, constantly change sighting distance and can make the people aggravate fatigue, last result attends to one thing and lose sight of another and is unfavorable for the raising of handling efficiency; The secondth, length of steel wire rope is judged box location with rope capacity merely along with the weight of freight container, the conditions such as temperature of steel rope change greatly, and its error is very big, the degree of fatigue that is difficult to reach efficient loading and unloading and reduces the driver.
Summary of the invention
The purpose of this invention is to provide in a kind of quayside container crane operation, quayside container crane operation spreader height real-time display guidance device is to overcome the deficiencies in the prior art.
Technology path of the present invention be rely on be installed on the suspender or the bridge crane driving compartment on laser range sensor, the location information of the spreader height that laser range sensor is measured, be transferred to control computer in real time accurately, and after carrying out data handing by software in the computing machine, the spreader height position is presented on the read out instrument as distance indicator in real time in the derivation graph mode, thereby make the driver in operator's compartment, can see the sign of the spreader height position on the read out instrument outside tens meters clearly, to realize guiding like clockwork.
Technical scheme of the present invention comprises the laser range sensor that is fixed on the bridge crane driving compartment, with the monolithic processor control device that is fixed on the band software program on the suspender, this monolithic processor control device is connected with the power supply of actuator and read out instrument and power supply, the data transmission of above-mentioned laser range sensor output is to monolithic processor control device, the output interface of this monolithic processor control device is connected on some actuators, and the output of actuator is connected with each display unit on the read out instrument.Above-mentioned laser range sensor can also or be fixed on the suspender.
Above-mentioned read out instrument is that a plurality of luminescence display units by the orderly arrangement in the metal framework that is fixed on the bridge crane suspender constitute, and in each display unit luminous element is installed.
The suspender differing heights position that the corresponding laser range sensor 1 of number luminous or that extinguish of the display unit of above-mentioned read out instrument is surveyed.
Characteristics of the present invention are the remote visual fields (promptly on suspender) bank bridge driver, spreader height to freight container shows in real time, thus guiding driver's loading and unloading operation accurately, and improve handling efficiency greatly, reduce driver's degree of fatigue, substantial economics and social benefit are arranged.Using the present invention will make single case on average lift the efficient raising reaches more than 20%.

The specific embodiment
As Fig. 1-3, the present invention includes the laser range sensor 1 that is fixed on the bridge crane driving compartment 7, with the monolithic processor control device 2 that is fixed on the band software program on the suspender 6, this monolithic processor control device 2 is connected with the power supply 5 of actuator 3 and read out instrument 4 and power supply, the data transmission of above-mentioned laser range sensor 1 output is to monolithic processor control device 2, the output interface of this monolithic processor control device 2 is connected on some actuators 3, and the output of actuator 3 is connected with each display unit 11 on the read out instrument 4.
Above-mentioned laser range sensor 1 can also be fixed on the suspender 6.
Above-mentioned read out instrument 4 is that a plurality of luminescence display units 11 by the orderly arrangement in the metal framework on the suspender 6 that is fixed on bridge crane 8 constitute, and in each display unit 11 luminous element is installed.This luminous element is a high brightness LED.
The differing heights position of the suspender 6 of the freight container that the display unit 11 of above-mentioned read out instrument 4 luminous or the number extinguished are surveyed corresponding to laser range sensor 1.
The structural arrangement mode of the display unit 11 on the above-mentioned read out instrument 4 is strip or fan-shaped pie chart, thereby formed the guiding display pattern and the bank bridge driver of being convenient to loading and unloading operation provides obvious box height to guide in real time.
Above-mentioned laser range sensor 1 is to adopt the laser range sensor of commercially available single-point type or the laser range sensor of scan-type.
Obviously, adopt the present invention to show guiding in real time for bank bridge driver provides the long sight distance box height, under guiding of the present invention, bridge crane driver's the case operation that falls is by the repeatedly exploratory decline of low speed of past, case finally slowly falls, become the manipulation freight container and accurately put in place in high-speed motion, the case success once falls.Improve container handling efficient and finally reach, reduce the casing impact acceleration, goods and the safety of delivery truck and the purpose that alleviates tired driver in the guard box.
