Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments of the present invention.
Referring to fig. 1, the present embodiment provides a jacking tool for a top pin of a container spreader, which comprises a top plate 1, a bottom plate 2 and an elastic expansion piece 3 connected between the top plate 1 and the bottom plate 2.
In order to facilitate the assembly and disassembly of the tool, the top plate 1 is a magnetic plate body and can be adsorbed on the top of a spreader frame 4 in a container spreader, as shown in fig. 2 to 4, the spreader frame 4 in the drawings is only shown schematically, and the specific structure of the spreader frame can refer to the prior art.
The top plate 1 and the bottom plate 2 are in a long strip shape, and the two sides of the top plate 1 and the two sides of the bottom plate 2 in the length direction are connected through the elastic telescopic pieces 3.
In order to increase the connection stability, two sides of the top plate 1 and the bottom plate 2 are respectively connected with 2 elastic expansion pieces 3.
In the tool of the present embodiment, the top plate 1 is attached to the top of the hanger frame 4, and the bottom plate 2 is suspended below the bottom of the hanger frame 4 through the connection of the elastic expansion piece 3.
After the lock head 5 of the container spreader lifts the container, the knock pin 6 is extended downwards to the locking position to lock the lock head 5. Receive the action of gravity of bottom plate 2, elastic expansion piece 3 is tensile and drive bottom plate 2 and transfer in the below of knock pin 6, has the determining deviation between bottom plate 2 and the knock pin 6, and bottom plate 2 does not influence the locking of knock pin 6 to tapered end 5.
During the process of landing the container, because the bottom plate 2 has a larger surface area relative to the top pin 6, after the container lands, the spreader continues to descend, and during the process of jacking the bottom plate 2 upwards from the top of the container, the bottom plate 2 gradually approaches the top pin 6 and finally jacks up the top pin 6 to an unlocking position.
This embodiment instrument is guaranteeing simple structure, easily makes, low in production cost simultaneously, has effectively solved because sunken 6 unable by the technical problem of normal jack-up of knock pin that leads to in container top.
Because the spreader frame 4 of the container spreader has a certain height, in order to avoid the elastic expansion member 3 from driving the bottom plate 2 to excessively shake, the elastic expansion member 3 of the present embodiment includes a connecting rod 31 and a spring 32.
The connecting rod 31 is a rigid rod body, one end of the connecting rod 31 is welded or in threaded connection with the top plate 1, the other end of the connecting rod 31 is welded or in hanging connection with one end of the spring 32, and the other end of the spring 32 is welded or in hanging connection with the bottom plate 2.
To accommodate spreader frames 4 of different heights, in some embodiments, the connecting rod 31 may be a telescopic connecting rod 31 that can be fixed at multiple lengths. The concrete implementation mode can refer to the existing umbrella rod structure or other electric telescopic mechanisms or hydraulic telescopic mechanisms, or the connecting rod 31 is a long rod consisting of a threaded rod and a threaded sleeve, and the length of the connecting rod 31 is adjusted through the threaded matching of the threaded rod and the threaded sleeve.
When the container spreader lifts a container, the spring 32 is stretched downwards by the weight of the base plate 2, and the base plate 2 moves downwards to clear the knock pin 6 in the locked position.
When the ejector pin 6 is jacked up by the bottom plate 2, the spring 32 recovers a certain stretching amount, the spring 32 still keeps a stretching state, and the stretched elastic telescopic piece 3 is beneficial to the vertical translation of the bottom plate 2.
In some embodiments, in order to guide the extension and retraction of the spring 32, the elastic extensible member 3 further comprises an extensible guide rod, one end of the extensible guide rod is welded with the other end of the connecting rod 31, the other end of the extensible guide rod is connected with the bottom plate 2 in a welded manner, the spring 32 is sleeved on the outer side of the extensible guide rod, when the spring 32 extends and retracts, the extensible guide rod and the spring 32 extend and retract synchronously, the structure of the elastic extensible member 3 can be strengthened, the spring 32 can also extend and retract linearly, and therefore the bottom plate 2 can be ensured to be always arranged opposite to the ejector pin 6.
In particular, the telescopic guide rod can be realized by two guide cylinders which are connected in a sleeved mode.
Based on the jacking tool for the jacking pin of the container spreader in the above embodiment, the utility model also provides an embodiment of the container spreader, it is shown with reference to fig. 2 to fig. 4, and it includes spreader frame 4 and establishes 6, the tapered end 5 at the jacking pin of spreader frame 4's bottom, still includes the jacking tool for the jacking pin of the container spreader in any embodiment of the aforesaid.
The top plate 1 is adsorbed on the top of the lifting appliance frame 4, and the bottom plate 2 is suspended below the bottom of the lifting appliance frame 4 through the connection of the elastic expansion pieces 3. After the lifting appliance is lifted, under the action of gravity of the bottom plate 2, the elastic expansion piece 3 stretches and drives the bottom plate 2 to be placed below the ejector pin 6 in the locking position, a certain distance is reserved between the bottom plate 2 and the ejector pin 6, and the bottom plate 2 does not influence the locking of the ejector pin 6 on the lock head 5.
To improve the accuracy of the tool mounting position, in some embodiments, a locating structure may be formed between the bottom of the top plate 1 and the top of the spreader frame 4.
The positioning structure may include a positioning groove formed at the bottom of the top plate 1 and a positioning protrusion formed at the top of the hanger frame 4.
The positioning structure may include a positioning protrusion formed at the bottom of the top plate 1 and a positioning groove formed at the top of the hanger frame 4.
To prevent the bottom plate 2 from interfering with other structures, the width of the bottom plate 2 does not exceed the diameter of the top pin 6 in this embodiment.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
