Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
As shown in Figure 1, a kind of crane in bridge type of the preferred embodiment of the present invention, comprises frame, control setup 4, first jack up unit 5, second jack up unit 6 and jacking system 7; Frame comprises first crossbeam 2 and is positioned at the second cross beam 3 of below of first crossbeam 2; Control setup 4 is located on first crossbeam 2; Jacking system 7 is connected with first crossbeam 2, and can move up and down between first crossbeam 2 and second cross beam 3.Jacking system 7 is provided with the detecting device be electrically connected with control setup 4, and detecting device comprises the first detecting element for elevation carrection and the second detecting element for weight measurement.First jack up unit 5 is located on first crossbeam 2, and can move along first crossbeam 2; Second jack up unit 6 is located on second cross beam 3, and can move along second cross beam 3.The present invention is provided with intermediate lift device, gives jacking system and completes, thus shorten the cycle of cargo handing by a lift work that originally must be completed by lifting trolley, and its structure is simple, efficient quick.
Wherein, update device 7 for detecting the height of goods, thus is located by the first detecting element; Second detecting element for detecting on update device 7 whether be placed with goods, thus determines the running condition of jacking system 7, and preferably, the first detecting element is infrared pickoff, and the second detecting element is weight inductor.Jacking system 7 specifically comprises bay-lift 71 and hoister winch 72; Hoister winch 72 is connected with bay-lift 71, moves up and down for driving bay-lift 71.In the present embodiment, jacking system 7 also comprises the anti-bias mechanism for preventing bay-lift 71 deflection.
In the embodiment of the present invention, the first suspender 52 that the first jack up unit 5 comprises the first dolly 51 and is located at below the first dolly 51; The second suspender 62 that second jack up unit 6 comprises the second dolly 61 and is located at below the second dolly 61.The below of control setup 4 is provided with ladder 8, and ladder 8 is connected with second cross beam 3.Capture goods 1 by the first suspender 52, then moved along first crossbeam 1 by the first dolly 51, thus drive the goods 1 under the first suspender 52 to move; Capture goods 1 by the second suspender 62, then moved along second cross beam 3 by the second dolly 61, thus drive the goods 1 under the second suspender 62 to move.Second jack up unit 6 is arranged on second cross beam 3, can avoids using longer hoist rope, only need shorter hoist rope is installed.Because hoist rope is long, goods 1 can be caused in the process of movement to produce more serious beat, and unloaded of cargo 1 need the cost longer time to aim at, and is unfavorable for the raising of handling efficiency.
Jacking system 7 arranges the detecting device be electrically connected with control setup 4, the object of efficient quick handling goods 1 can be reached.Concrete, before lade 1, the first detecting element can detect the height of the first jack up unit 5 smoothly, sends this signal to control setup 4, and control setup 4 controls jacking system 7, and jacking system 7 is risen to corresponding height, thus lade 1; Or after jacking system 7 lade 1, the first detecting element can detect the height of the second jack up unit 6 smoothly, send this signal to control setup 4, control setup 4 controls jacking system 7, and jacking system 7 is risen to corresponding height, thus unloaded of cargo 1; Again or, after jacking system 7 unloaded of cargo 1, second detecting element can detect that jacking system 7 is for empty, then send this signal to control setup 4, control setup 4 controls jacking system 7, jacking system 7 is risen to the height corresponding to now goods 1 Cargo On Deck 1 pile, continues the goods 1 on reception first jack up unit 5.
As shown in Figure 2, the material of anti-bias mechanism is preferably steel column.Anti-bias mechanism can prevent bay-lift 71 in the process of operation, bay-lift 71 is caused to produce large rocking because of the impact of the factors such as the weight of goods 1 or inclement weather, goods 1 is caused to be dropped down from bay-lift 71, cause unnecessary loss or injury, the present invention has the stable feature of handling.Wherein, anti-bias mechanism comprises anti-bias guide rail 73, anchor ear and horizontal roller, anchor ear is fixed on bay-lift, anchor ear is provided with two row of horizontal rollers, anti-bias guide rail 73 passes between two row of horizontal rollers, and anchor ear is equivalent to a kind of fixture, is located on the holding part of anchor ear both sides at horizontal roller, by to tighten up or lax anchor ear can realize the clamping of two row of horizontal rollers and lax, and then realize the clamping of anti-bias guide rail 73 and lax.Preferably, anti-bias guide rail 73 is for being located at four of bay-lift 71 periphery, and horizontal roller is four corresponding with anti-bias guide rail 73, and often row arranges two.By anchor ear tightening up and lax, adjust the contact gap of horizontal roller and anti-bias guide rail 73, regulate horizontal roller to the enclasping force of anti-bias guide rail 73 thus, can be used for the horizontal location of guarantee bay-lift 71.Concrete, horizontal roller slides along anti-bias guide rail 73, when bay-lift 71 stops no longer being elevated, tightens up anchor ear, reduces the gap between horizontal roller and anti-bias guide rail 73, and horizontal roller holds anti-bias guide rail 73 tightly, thus guarantees that bay-lift 71 is steady; When in bay-lift 71 lifting process, anchor ear is relaxed, increase the gap between horizontal roller and anti-bias guide rail 73, horizontal roller contacts with anti-bias guide rail 73 but does not hold tightly, horizontal roller and anti-bias guide rail play the effect of location, guiding in bay-lift 71 lifting process, and then can prevent from shaking in lifting of lifting table process.
Present invention also offers a kind of cargo handing method based on above-mentioned crane in bridge type, comprise the following steps: first, first detecting element detects the height of goods 1 pile, and send testing result to control setup 4, control setup 4 controls jacking system 7, and bay-lift 71 is risen to the height corresponding to goods 1 pile; Afterwards, the first jack up unit 5 captures goods from goods 1 accumulation, and moves to jacking system 7 place along first crossbeam 2, and bay-lift 71 receives goods 1; Then, the second detecting element detects, and jacking system 7 has goods 1, and sends signal to control setup 4, and control setup 4 controls bay-lift 71 and declines; Subsequently, the second jack up unit 6 captures the goods 1 on bay-lift 71, moves to unloading place, unloaded by goods 1 along second cross beam 3, completes the handling process of goods 1.
In addition, when the second suspender 62 captures after goods 1 from bay-lift 71, the signal that the bay-lift 71 detected is blank state by the second detecting element sends control setup 4 to, control setup 4 controls bay-lift 71, bay-lift 71 is risen to the height corresponding to now goods 1 pile, waits for the first jack up unit 5.When the first suspender 52 sends goods 1 to bay-lift 71, after bay-lift 71 receives goods 1, the first suspender 52 is back to goods accumulation place.Set these two kinds of steps above-mentioned, the loadingunloading time of goods 1 can be greatly reduced, by the relay effect of jacking system 7, the object of efficient quick can be realized better.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and replacement, these improve and replace and also should be considered as protection scope of the present invention.
