Abstract
A kind of gantry crane self-balancing hydraulic pressure container spreader, comprise rotating hanger, rotating hanger is provided with bull gear between lower body, the four wheels that two groups are clipped in both sides is respectively installed between rotating hanger lower body and container spreader, control motor and hydraulic efficiency pressure system by a balanced system, it is characterized in that: hydraulic efficiency pressure system is arranged on upper frame; Micro limit switch (1A, 1B), trammel beam (2), weight (3), adjusting lever (4) are installed concentratedly at lower frame, close with protective housing; Wheel (8) is arranged on upper frame, and lower frame is equipped with wheel runway; Stop and be arranged on lower frame.Gantry crane self-balancing hydraulic collection vanning hanger device of the present utility model, can remain that hung freight container is in state of equilibrium, due to hydraulic efficiency gear strength uniform and stable at work, is not easy to cause hung freight container to produce vibration, stable and reliable for performance.
Description
technical field:
The utility model relates to the gantry crane self-balancing hydraulic collection vanning hanger device that cargo handing gantry crane takes oil cylinder to manipulate
background technology:
Railway goods yard suspension bracket used, when lifting container, because the load in hung freight container can not be evenly distributed, has skew during lifting center of gravity, causes hung container tilt, causes goods to slide in freight container, easily accidents caused.For this reason, container spreader must have the function of automatic center-of-gravity regulating, gantry crane self-balancing hydraulic collection vanning hanger device automatically can adjust loaded weight inequality in freight container at any time and cause hung container tilt, not only increase the efficiency of container handling, be also conducive to the safety ensureing loading and unloading container.
The current employing in goods yard be three-in-one electric drilling match deceleration screw rod push-and-pull adjustment reason center of gravity (namely three-in-one motor, drop-gear box, drg), driving power is large, and consumption of current is large; Due to structure bulky, manufacturing cost is high, causes gantry crane self-balancing hydraulic pressure container spreader overweight; Also three-in-one motor is easily caused to burn out and screw rod push-and-pull fault of slowing down.When hung container tilt, gantry crane driver's cab driver can only rely on ground staff to command, and carries out center of gravity displacement adjustment to hung tilting container; Not only strengthen the working strength of ground staff, and easily cause because information communication problems wrong causes gantry crane self-balancing hydraulic pressure container spreader left and right horizontal sense of displacement to make a mistake, cause hang the freight container being in inclination and more tilt, cause safety misadventure.
summary of the invention:
It is simple that the purpose of this utility model is just to provide a kind of structure, and stable working, stable performance, consumes energy low, the gantry crane self-balancing hydraulic pressure container spreader of low cost of manufacture.
A kind of gantry crane self-balancing hydraulic pressure container spreader, comprise rotating hanger, rotating hanger is provided with bull gear between lower body, bull gear is by being arranged on the three-in-one mechanism of rotating hanger upper body, bull gear is driven to rotate by planetary wheel, suspension bracket can rotate between lower frame mutually, the four wheels that two groups are clipped in both sides is respectively installed between rotating hanger lower body and container spreader, motor and hydraulic efficiency pressure system is controlled by a balanced system, it is characterized in that: hydraulic efficiency pressure system comprises oil cylinder (7), micro limit switch (1A, 1B), trammel beam (2), weight (3), adjusting lever (4) is concentrated and is closed with protective housing, wheel (8), stop (9), hydraulic efficiency pressure system is arranged on upper frame, micro limit switch (1A, 1B), trammel beam (2), weight (3), adjusting lever (4) are installed concentratedly at lower frame, close with protective housing, wheel (8) is arranged on upper frame, and lower frame is equipped with wheel runway, stop and be arranged on lower frame.
Gantry crane self-balancing hydraulic pressure container spreader of the present utility model, oil cylinder (7) and upper frame (5) are fixedly connected, and piston rod stops that with lower frame (9) are connected; Wheel (8) is connected with upper frame (5), stops that (9) are connected with lower frame; Trammel beam (2) and movement weight rod form T-shape, weight (3) slip seals in adjusting lever and locates with adjusting nut, the left and right sides of trammel beam (2) installs travel switch 1A, 1B respectively, and above each is all assembled in a closed box and is fixed on lower frame (6).
Gantry crane self-balancing hydraulic collection vanning hanger device of the present utility model, can remain that hung freight container is in state of equilibrium, at this moment hydraulic ram does not work, and just keeps pressure; Due to hydraulic efficiency gear strength uniform and stable at work, be not easy to cause hung freight container to produce vibration, stable and reliable for performance.
