The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
The utility model is made of added 4, undercarriage 5, main beam member, four lock casees 18 and hydrostatic drive section, main beam member comprises girder 2 and 2 40 feet suspension bracket end carriages 3 of 2 20 feet suspension bracket end carriages 1, two ends band interface, form on 20 feet suspension bracket end carriages 1 and girder 2 interface that is complementary, form the extending beam 3-1 vertical and integrally formed with its end on 40 feet suspension bracket end carriages 3, the extending beam 3-1 other end forms and girder 2 interface that is complementary, and 20 feet suspension bracket end carriages 1,40 feet suspension bracket end carriages 3 all can be connected with girder 2 or dismantle by interface.Only corresponding end carriage spiral-lock can need be used to girder during use.
The utility model hydrostatic drive section comprises anti-turn round/shake section, self-balancing section, twist lock section.
Referring to Fig. 4: the anti-turning round/section of shaking is installed on the gantry crane crane carriage, is made of oil motor 7, the first electromagnetic valve 8, energy storage 9, the first hydraulic power unit 10.The first hydraulic power unit 10 output terminations the first electromagnetic valve 8 P mouths reach and energy storage 9 mouths, and the O mouth of the first electromagnetic valve 8 connects the fuel tank of the first hydraulic power unit 10, and the A of the first electromagnetic valve 8, B mouth connect respectively oil motor two ends (two oil motor parallel connections).Two steel wire rope rolls of two oil motors, 7 controls, two steel wire rope roll two steel ropes in parallel are connected with added 4 four jiaos by four steel ropes, to realize preventing turning round, shaking purpose.
A 7.5KW electric motor driven oil pump continuous firing, pressure oil makes two hydraulic motors produce constant-torque by pipeline, simultaneously also to energy storage pressure store oil.Following three kinds of operating mode: a, suspension bracket rotation are arranged: this moment, the hydraulic motor of constant-torque made wire rope pulley produce constant-torque by planet-cycloid reducer, can make every steel rope produce the pulling force of about 1000kg.Thereby make suspension bracket prevent turning round to shake smoothly carrying out.B, gantry crane main hook descend; This moment, the anti-steel rope that shakes was elongated (because suspension bracket is conducted oneself with dignity greater than the anti-rope tension that shakes) synchronously, but steel rope still keeps constant pulling force.C, gantry crane main hook rise; Oil pump and energy storage made it forward, dragged steel rope drag hook Synchronous lifting to two hydraulic motor fuel feeding synchronously this moment, but still kept constant pulling force.The utility model is that system controls automatically: hydraulic system pressure is decided to be 6Mpa, when pressure reaches maxim (6Mpa), and the motor auto-stop, system must press, and Pressure Drop is during to 4.5-5Mpa, and again Auto Power On work is to 6Mpa auto-stop again.Such one is energy-conservation, and two also make the oil temperature can be not too high.(annotate: because rotating lock mechanism adopts hydrostatic drive, can make changing the outfit of end carriage become very convenient quick, as long as slippage hydraulic quick coupling.
Referring to Fig. 5, self-balancing section is installed in the girder 2 of suspension bracket, is made of first, second double acting single-piston rod oil cylinder 11-1,11-2, the second solenoid directional control valve 12, the second hydraulic power unit 13.First, second double acting single-piston rod oil cylinder 11-1,11-2 two rod end oil pockets connect respectively the second solenoid directional control valve 12 A mouths, B mouth, first, second double acting single-piston rod oil cylinder 11-1, the interconnection of 11-2 other end hydraulic fluid port.The hinge-point at first, second double acting single-piston rod oil cylinder 11-1 of self-balancing section, 11-2 two ends is connected with girder with undercarriage 5 respectively and is connected, and relative with the girder center of symmetry, the symmetrical installation.
A 5.5KW motor-driven oil pump, when suspension bracket produced because of container unbalance-loading, the self-balancing section pendulum that is placed in suspension bracket made the oil pump running because tilting to trigger synchronously approach switch, also connects the second solenoid directional control valve simultaneously.When pressure oil was oil-filled to oil cylinder, oil cylinder made between hanger main beam and the undercarriage and produces relative displacement, and when suspension bracket tilted to change level into because barycenter displacement makes, self-balancing section pendulum also resetted approach switch because recovering horizontality, thereby oil pump → oil cylinder is quit work.When freight container because of unbalance loading make suspension bracket produce reciprocal when tilting the reverse self-balancing operating principle of suspension bracket the same.
Referring to Fig. 6, twist lock section is made of the 3rd hydraulic power unit 14, the 3rd solenoid directional control valve 15 and first, second double acting double rod cylinder 16-1,16-2.(fuel tank and hydraulic oil are then total with self-balancing section.）
First, second double acting double rod cylinder 16-1, the series connection of 16-2 oil circuit, the 3rd hydraulic power unit 14A mouth, B mouth are connected with first, second double acting double rod cylinder 16-1, the 16-2 other end respectively.The piston rod of first, second double acting double rod cylinder 16-1,16-2 connects respectively the lock case 18 that is arranged at respectively corresponding end carriage both sides and connects (referring to Fig. 2).First, second double acting double rod cylinder 16-1 of twist lock section, 16-2 are arranged at respectively in 20 feet suspension bracket end carriages 1 or the 40 feet suspension bracket end carriages 3.
Four jiaos of suspension bracket are equipped with four lock casees.Four twist lock bars stretching down, four lockholes with four jiaos in freight container are corresponding respectively, and after the twist lock bar inserted the freight container lockhole, half-twist is about to suspension bracket and freight container locks mutually, thereby realized the handling of freight container.After container in hoisting status finishes, only need four twist lock bar synchronous backward half-twists, can make between suspension bracket and the freight container to break away from.(hydraulic principle of twist lock section is identical with self-balancing section, and just power of motor and cylinder sizes are much smaller.Because the self balance oil cylinder maximum thrust reaches 15000kg, and the twist lock cylinder thrust only needs 200kg).Forward and reverse action of twist lock section is controlled by gantry crane driver hand switch crawl.
