The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
The present embodiment provides a kind of high-mobility, multipurpose, wheeled vehicle double-hung tower machine, as shown in Figure 1, comprise tower body 11, lifting mechanism 5, swing type mechanism 9, motor, control desk, described lifting mechanism 5 two covers that be arranged in parallel on the equilibrium arm 3 of tower machine, and by two, overlap independently lift controlling system and control, play lift operations actuating device also independent separately, guarantee traction element energy independent operating.
As shown in Figure 2, two loading trolleys 15 of lifting mechanism 5 respectively with crane arm 8 on the double track sliding block joint that be arranged in parallel of two covers, a track 16 of every cover double track is arranged at one side shoulder of crane arm 8, another track 16 is arranged at the middle part of crane arm 8, and asymmetric two-orbit 16 designs of structure height have guaranteed that the operation of two loading trolleys 15 is non-interference.
As shown in Figure 3, described outside motor setting has the guard shield 19 that sound-absorbing foam material is filled, and running noise of motor is hedged off from the outer world out, and can meet spot effect, reduce running noise and occur mixing with performance audible sound, while making system running, keep low noise state.
Movable decking 12 and people from station platform 13 of described tower body 11 distribution multilayer installing light and sound equipment, and can pack up platform as required.
Further, above-mentioned sound-absorbing foam material can be poly-ester fibres acoustical cotton 18.
Further, above-mentioned lifting mechanism 5 has lift hook position detecting device and the anti-interference checking device of steel rope.Lift hook position detecting device, reminds operating personal to note if the relative position of 2 suspension hooks 17 lower than 2m, sends sound and light alarm; The anti-interference checking device of steel rope, if it is stressed abnormal to meet the wirerope-winding body that causes restricting, steel rope interference checking device is the operation of the suspension hook 17 that stops hoisting, and can prevent that the wirerope-winding body that causes restricting is stressed abnormal.
Described motor, by its horsepower output of Frequency Converter Control, reaches by changing the frequency of operation of electrical motor the object that changes motor speed, realizes tower machine heavy duty high speed, underloading low speed.Adopt variable-frequency control technique, by changing the wavelength of alternating current, the exciting current of motor is increased, produce excitation noise simultaneously, along with the increase of frequency, this noise can reduce, thereby reaches the object of active noise reduction.
Further, adopt frequency converter closed loop control and PLC technology to combine, be that above-mentioned lift controlling system is PLC controller, on the output shaft of described motor, speed detector is set, the speed of Real-Time Monitoring motor, and this speed detector connects with PLC controller signals, and velocity information is sent to PLC controller and frequency converter.Synchronous with it, PLC controller connects with the frequency converter signal of motor, keeps real-time communication, the running state of the information co-controlling frequency converter that comprehensive speed detecting device is given.In PLC controller, be provided with main performance constraint program and the synchro control program that makes device of operation, assurance level, lifting velocity evenly, synchronous, steadily, and should be substantially when rise/braking without impact with rock.
Further, above-mentioned control desk is arranged in the machine room 14 on ground.Adopt ground machine room centralized control, solved because complete machine is higher, be not easy to observe the problem of surface state.
Further, as shown in Figure 4, in each closed cross-sections such as the main chord of above-mentioned tower body 11, crane arm top boom, crane arm lower boom, diagonal web member internal cavities, web member, fill absorbing material, on the upper and lower bearing turn table of described tower body 11 and counterbalanced weight near etc. large inertial position shock-absorbing means is set, as shown in Figure 5 or Figure 6.Solved because complete machine is higher, flexibility is very large, and during operation, its distortion large and fall time very longly can not meet the problem that performance requires.
Further, above-mentioned absorbing material is the compound of the polypropylene expanded particle 21 of EPP and poly-ester fibres acoustical cotton 18, described shock-absorbing means silicone oil damping dissipation energy device.
Further, the counterbalanced weight of above-mentioned tower body 11 divides polylith to install successively along equilibrium arm length direction, and between each piece, utilizes its mutual jam-packed of conducting oneself with dignity, and eliminates the swing factor of counterbalanced weight.
Further, above-mentioned swing type mechanism 9 at tower machine during in off working state (such as, when static) remove rotary braking, to allow crane arm 8 to freely swing with the wind, under off working state, swing type mechanism 9 allows jib to freely swing with the wind, tower machine area exposed to the wind while attacking to reduce storm wind; On the crane arm long draw 25 of described tower body 11, increase damper 6 vibration dampings, as shown in Figure 7, the crane arm 8 square-section rod members of described tower body 11 are provided with the bar rib of continuous control crosswind resonance, control crosswind resonance.Solved because equipment is arranged on as opening along the river, over against river surface, wind is not only large and frequent, and structure generation wind shakes and makes equipment produce too early the problem of endurance failure.
Further, the crane arm top boom of above-mentioned tower body 11, crane arm lower boom, diagonal web member all adopt weathering steel material, and spray weather-proof paint after zinc-plated again.Because equipment is arranged on along the river, ambient humidity is large, adopts multiple-anticorrosion technology to slow down steel structure and gets rusty.
From tower machine in the past adopt more the installation forms such as single lifting mechanism, single-variable-amplitude mechanism different be, in order to adapt to the requirement of stage performance, this tower machine has adopted two lifting mechanisms, two luffing mechanism, two loading trolley, double-hung, full frequency conversion version in mechanism controls.The all corresponding luffing mechanism of each lifting mechanism, a loading trolley, a suspension hook and a set of control system.Two lifting mechanisms adopt one in front and one in back left and right dislocation collocation form at equilibrium arm, and a rope-arranging mechanism is all set separately before each lifting mechanism, and mechanism can independent operation.Two luffing mechanisms are installed on derrick runway girder, have also taked one in front and one in back left and right dislocation collocation form, independent operation.Hoisting arm structure has also been made special change, is provided with two-orbit, two loading trolley, double-hung on crane arm.Two loading trolleys are independently controlled, and can on crane arm, along large arm, move back and forth alone.Tower machine operation system is no longer positioned in operator's compartment, but arrange on the ground separately, operating personal is controlled each mechanism on ground, by hoist rope and variable-amplitude steel wire rope, drive two loading trolleys to move forward and backward, control hoisting, declining of suspension hook, thereby helped performance.Consider the needs of stage performance simultaneously, on tower body, be also provided with a plurality of sound equipments, lighting platform and a reach platform.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvement or distortion, these improvement or distortion also should be considered as protection domain of the present utility model.
