[0022] In order to make the purpose, characteristics and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be described clearly and completely in combination with the drawings in the specific embodiments below. Obviously, the embodiments described below are only some of the embodiments of the utility model, not all. Based on the embodiments in the patent, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the patent.
[0023] As Figure 1 shown, a container hanger comprises a hanger body, Figure 1 is a top view of the hanger body, the hanger body is a welded structure as a whole, the hanger body comprises two cross beams 5 and two longitudinal beams 6, the cross beam 5 and the longitudinal beam 6 form a rectangular structure, a plurality of support beams are further arranged between the two cross beams 5, the support beams are parallel to the longitudinal beams 6, the cross beam 5 is an I-beam, the longitudinal beam 6 is a hollow square beam, a locking tongue is arranged at the bottom surface of each end of the longitudinal beam 6, a locking tongue driving structure is arranged in the longitudinal beam 6, the locking tongue driving structure drives the locking tongue at the two ends of the longitudinal beam to rotate, this is the conventional structure of the container hanger, and will not be described here.
[0024] In the present scheme, a plurality of support assemblies are further arranged on the hanger body, and are specifically arranged on the two cross beams 5, the support assemblies on the two cross beams 5 are one-to-one opposite, in the present embodiment, four groups of support assemblies are arranged, and the four groups of support assemblies are arranged in a rectangular shape. It can be understood that in other embodiments, the support assemblies can also be other quantities, for example, for a container hanger with a larger length, more support assemblies can be arranged.
[0025] As Figure 2 , 3As shown, the support assembly includes a mounting base 7, adapted to the I-beam design of the crossbeam. The mounting base 7 adopts a channel steel structure, that is, the mounting base 7 includes two channel wall plates and a channel bottom plate. In the installation state shown in the figure, the channel wall plates are horizontally set, and the two channel wall plates are fixedly connected to the two flanges of the I-beam by welding or other methods. Furthermore, the channel bottom plate of the channel steel is located on one side of the crossbeam, and a support sleeve 1 is fixedly installed on the side of the channel bottom plate facing away from the crossbeam. The support sleeve 1 is a square steel tube, and one side is welded and fixed to the mounting base 7. It has a vertical inner hole. It can be understood that when the container crane is used and stored, the plane on which its frame is located is basically in a horizontal state, that is, the axis of the inner hole of the support sleeve 1 is vertical. A support foot 2 is slidably installed in the inner hole of the support sleeve perpendicular to the plane of the container crane. A locking structure is provided between the support foot 2 and the support sleeve 1. The locking structure includes a first pin hole 3 and multiple second pin holes 4. One of the first pin hole 3 and the second pin hole 4 is located on the support sleeve 1, and the other is located on the support foot 2. A locking pin 7 is inserted into the first pin hole 3 and any second pin hole 4 to fix the relative position of the support sleeve 1 and the support foot 2. In this embodiment, the first pin hole 3 is located on the support sleeve 1, and the second pin hole 4 is located on the support foot 2, so that the second pin holes 4 can have a larger spacing, thereby allowing the support foot to have a larger range of extension and retraction.
[0026] The locking structure has a first locking state and a second locking state through the cooperation of the first pin hole with second pin holes at different positions:
[0027] like Figure 3 As shown, in the first locked state, the first pin hole is connected to the second pin hole located on the upper part of the support foot. At this time, the lower end of the support foot 2 is lower than the horizontal position of the locking tongue, and the bottom plate 21 of the support foot 2 can be supported on the ground.
[0028] like Figure 2 As shown, the upper end of the support leg 2 is provided with a handle 22. By pulling the support leg upward, the support leg 2 rises relative to the support sleeve. In the second locked state, the first pin hole is connected to the second pin hole located at the lower part of the support leg. At this time, the lower end of the support leg 2 is not lower than the horizontal position of the locking tongue, so that it will not interfere with the position of the container.
[0029] It should be noted that the second locking state is not necessary. As can be seen from the above structure, in the unlocked state, the support leg can slide freely relative to the support sleeve. When lifting the container, the jack approaches the container from top to bottom. When the landing plate 21 contacts the container, it will not affect the jack's continued downward movement.
[0030] The utility model discloses beneficial effect lies in, through setting up support subassembly on container hanger, when idle and place on ground, need not lend the aid of other support such as fender and can make lock tongue and ground disengagement contact, reduced operating risk, through the support foot of telescopic and locking, support subassembly supports stable and reliable, is not easy to be interfered with environment, when hanger uses, still can lock up and receive support foot, avoided the position interference to container, ensured the smooth operation, the connecting form of lock pin and pin hole makes the connection positioning of support sleeve and support foot convenient, guarantees the high strength of connection simultaneously, the layout of support subassembly and hanger shape are adapted, provided greater support area, further strengthened the stability of whole, the rectangular arrangement of four groups of support subassembly, ensured the balance of hanger, the face face connection form of mounting seat and crossbeam, improved the connection strength, ensured the durability, finally, the ground plate design of support foot lower extreme, increased the ground area, reduced the pressure of ground, protected the ground not to be damaged.
[0031] The above description of disclosed embodiments enables those skilled in the art to make or use the present application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
