Details of several anti-rolling systems of the tyrotype container gantry crane?

Answer:

Rubber-tyred container gantry crane of a terminal company (hereinafter referred to as the gantry crane) by Shanghai zhenhua port machinery co., LTD. (ZPMC), Shanghai port machinery heavy industry co., LTD. (SPMC), Noel lifting equipment (China) co., LTD. (NOELL crane manufacturers such as manufacturing, phyletic and various. However, there are different ways of using the crane system, which is different from each other. When the suspension is suspended, the cargo will be shaken and how to prevent the shaking from being a common problem for all cranes. For gantry crane, the stabilizer system refers to the sling lifting container, in the case of cars, cart translation, the swing in a certain period, container to fulfill the requirements of recognized on the box, a good rolling system can play a good damping effect, has greatly raised Labour productivity. The following is the analysis of several anti-rolling systems used in the dragon door crane.

4 hoisting wire rope cross winding way 4 1 institution arrangement and working principle of the four hoisting rope pulley, directly from the drum to sling the shelves on the pulley cross winding (different from normal winding). Then the transition from the car frame and the steering pulley back to the hoisting mechanism. This arrangement fully consider the car frame pulley offshoring lifting point as far as possible, in order to realize the hoisting wire rope in the direction of the horizontal component of the car is enough big, depends on this component to achieve the function of spreader in the car direction stabilizer. When the lifting gear starts to swing, the horizontal component of the other side of the raised wire will hold down the swing of the harness. The anti-rolling effect of this arrangement is obvious. The pulley of the wire rope is small, four rising wire rope length is consistent, the winding form is unified, can reduce the difficulty of maintaining the work. Simplifies the car arrangement, the car on the shelf arrangement organization completely symmetrical, avoid the happening of the partial load in traditional design, make the stress of the structure form more hasten is reasonable.

The system consists of hoisting drum, pulley and 8 lifting wire rope. Eight eight rope head of wire rope with wire rope clamp and screw fixed on the drum, wire rope of eight rope head of each other around the car on the pulley, rope head of a group, in two oblique cross connection with flower basket screws at the midpoint of the special sling on every side, consists of four equal isosceles triangle, respectively. The working principle USES the geometry principle of triangular stability to change the traditional lifting winding system to four identical inverted triangle systems. 8 eight rope winding system of wire rope are skew on the hanger, the horizontal component of the spreader in the direction of the cart and the car stopped swinging, pour triangular systems to improve the rigidity of suspension system, namely like a rigid connection between cars and spreader, when the small car after starting and braking, sling (including goods) with brake, fundamentally eliminate the swing of the sling.

Hydraulic pressure stabilizer 2 1 stabilizer of stabilizer by drum roll reduction, stabilization, reversing the pulleys and transition pulley, wire rope of the hydraulic cylinder and a set of hydraulic system. The roll-down drum is driven by an open-type gear through an open gear, and it is operated in synchrony. The hydraulic cylinder is placed on the shelf, and the hydraulic cylinder pressure is provided by a hydraulic unit that is also placed on the shelf. The hydraulic system is composed of the following five parts: from the hoisting device to the oil outlet, the control valve block of the hydraulic valve, the pressure switch and the four hydraulic pressure hydraulic system. 30?? # crane transport machinery?? 2007 (6) cylinder, hydraulic accumulator and safety module.
