Abstract
The utility model relates to a powerless twist lock control device for a container hanger. The utility model is characterized in that a plate is arranged on a transmission shaft which drives a crank link mechanism and twist locks to rotate. The interior of the plate is provided with a guide groove and a movable component which slides along the guide groove in rolling. The movable component is connected with a hook through a buffer spring and a driving rope. The motion of the movable component is controlled by an eccentric locking block. The plate is provided a positioning block for limiting the rotation angles of the plate and the twist locks. When using, the eccentric locking block can lock or unlock the movable component through the elevation of the hook. The movable component either drives the plate to rotate or rolls along the guide groove. Thus, forward and backward rotating actions of the plate and the twist locks in 90 DEG are achieved. The utility model has the advantages of simple structure, easy manufacturing, low cost, and convenient disassembly and maintenance, etc.
Description
The utility model relates to a kind of unpowered container spreader twist lock control setup, belongs to the load that is used for hoisting crane, capstan winch, winch or coaster and hangs element or device.
In the prior art, unpowered container spreader roughly can divide two classes: 1. manual operation twist lock action; 2. by the action of rising and falling of suspension hook, drive the action of transmission mechanism control twist lock.From the domestic existing product, the second class container spreader is more, the 5D type container spreader of using as 5 tons of freight containers, the control method of its blockade is: suspension hook at first affects the transmission rope of control setup, by recoil spring pulling ratchet, promotes ratchet and rotates, thereby drive transmission shaft, piston crank mechanism, and then rotate twist lock, make suspender pin freight container and maybe can extract from freight container.Its weak point is that the structure of ratchet, ratchet is complicated, and processing difficulties is installed and adjusted trouble, cost height.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provides a kind of simple in structure, and unpowered container spreader twist lock control setup easy to adjust, with low cost is installed in processing easily.
The purpose of this utility model can reach by following measure:
On the transmission shaft that drive piston crank mechanism, twist lock rotate plate is installed, with pin or screw retention, transmission shaft rotates with plate; The movement parts that guide groove is arranged in the plate and roll or slide along guide groove, guide groove two stomidium centers and transmission shaft axle center line are orthogonal; Movement parts links to each other with transmission rope by recoil spring; Guide groove two stomidium sides have can be around the eccentric lock dog of bearing pin swing, and when the guide groove stomidium was positioned at level attitude, eccentric lock dog pinned the stomidium mouth; Locating piece is arranged on the plate, and the transmission axle bed has stops on the corresponding position, and when the guide groove stomidium was positioned at level or upright position, locating piece and stops were collided.
The purpose of this utility model can also reach by following other measures.
Eccentric lock dog of the present utility model (10) is made up of eccentric body, lock flange and pin shaft hole, and eccentric body utilizes the pin shaft hole sky to be enclosed within on the bearing pin of guide groove stomidium side.
Guide groove is straight line groove or curved groove in the plate of the present utility model.
The unpowered container spreader that Fig. 1 the utility model proposes for basis twist lock control setup scheme drawing.
Fig. 2 is positioned at the guide groove stomidium for twist lock control setup movement parts, is in vertical position.
Fig. 3 is positioned at another stomidium of guide groove for twist lock control setup movement parts, is horizontal.
Below in conjunction with details and the service condition of accompanying drawing detailed description according to the concrete device that the utility model proposes.
According to unpowered container spreader twist lock control transmission meaning diagrammatic sketch such as the Fig. 1 that the utility model proposes.When freight container need be sling, hoisting crane is sling suspender, because the deadweight of suspender, tight transmission rope of suspension hook band (1) and buffering spring (2), movement parts (8) is positioned at line channel (7) stomidium (13), eccentric lock dog (10) is because of the action of gravity of eccentric body (17), and lock flange (18) leaves guide groove stomidium (13) mouth, is Fig. 2 state.Suspender lies against the container body top, four twist locks on the suspender insert back Panasonic suspension hook in the container apex angle hole, transmission rope (1), recoil spring (2) be Panasonic thereupon also, movement parts (8) is rolled downwards or is slided along with guide groove, because the weight of movement parts, force eccentric lock dog (10) to rotate, lock flange (18) leaves guide groove stomidium (14) mouth, movement parts (8) enters line channel (7) end, eccentric lock dog (10) is because the action of gravity of eccentric body (17), lock flange (18) resets and pins guide groove stomidium (14) mouth, is Fig. 3 state.This moment, the crane lifting suspender affected transmission rope (1), recoil spring (2), and because of lock flange (18) pins the aperture, movement parts (8) drives plate (6) and rotates, and forces transmission shaft (3), piston crank mechanism (5) action to drive twist lock and rotate.Movement parts (8) is when being in vertical position, twist lock just in time turns over 90 °, and the locating piece (11) on the plate (6) is collided with the stops (12) on the transmission axle bed (4), stops the rotation of plate (6), guide groove stomidium this moment (14) is positioned at the upright position, and guide groove stomidium (13) is positioned at level attitude.If further promote suspender, suspender is together mentioned freight container, hoisting crane with container crane to assigned address, Panasonic's suspender, this moment similar Fig. 2 situation, different is the symmetry direction that line channel (7) position is in original position, identical with aforementioned principles, further Panasonic suspender, movement parts (8) enter guide groove stomidium (13) mouth, if promote suspender, movement parts (8) forces plate (6) to rotate in the opposite direction, even also twist lock resets, when movement parts (8) when being in vertical position, twist lock just in time turns over 90 °, locating piece (11) on the plate (6) is collided with the stops (12) on the transmission axle bed (4), stop the rotation of plate (6),, can extract suspender from the container body top if further promote suspender.Repeat above-mentioned action when hanging next freight container again.
Guide groove (7) in the plate (6) is curved groove also, and its operating principle is with aforementioned.
The utility model compared with prior art has simple in structure, handling ease, and cost is low, overhauls the advantages such as convenient, can be widely used in container handling or the stacking of harbour, railway, transporting something containerized warehouse, each traffic and transportation sector.
