Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of container fittings, and more specifically, to a telescopic lifting pile and a container. Background Art
[0002] When a container is transported and stored, it often needs to be lifted, loaded and unloaded, and moved. These operations will cause great impact on the container. In order to meet these operating conditions and facilitate the storage and transportation of the container, container corner fittings are generally provided on the container.
[0003] The weight of large container products is usually more than 10 tons. Only using corner fittings for lifting, loading and unloading, and moving often has the following limitations: corner fittings are usually distributed at the corners of the container. If only using corner fittings for lifting, the stress points may be too concentrated, increasing local stress; when the container is heavy, the stability during the lifting process may not be guaranteed, etc.
[0004] Therefore, in the prior art, several lifting piles are generally provided on the bottom longitudinal beam of the container to increase the lifting connection points. However, the lifting piles in the prior art are generally of a fixed structure. After the lifting, loading and unloading, and moving are completed, they always protrude outside, which brings inconvenience to the passage of operators. Summary of the Utility Model
[0005] In view of this, the main purpose of the present utility model is to provide a telescopic lifting pile to solve the problems existing in the prior art.
[0006] To achieve the above purpose, the technical solution of the present utility model is as follows:
[0007] A telescopic lifting pile is installed on the frame beam of a container. The lifting pile includes an installation sleeve and a pile body. A reinforcing rib plate is arranged on the outer side of the frame beam. Through holes for installing the installation sleeve are formed in the frame beam and the reinforcing rib plate. The installation sleeve is fixedly installed in the through holes. The pile body is movably arranged in the installation sleeve. One end of the pile body extends outward along the installation sleeve to the outside of the frame beam and is provided with a first limiting plate. The other end of the pile body extends inward along the installation sleeve to the inside of the frame beam and is provided with a second limiting plate.
[0008] Further, the second limiting plate is integrally formed with the pile body; the first limiting plate is detachably connected to the pile body.
[0009] Further, an oil injection hole is formed in the outer side end of the pile hanging body, a first oil passage communicating with the oil injection hole and a second oil passage communicating with the first oil passage are formed inside. The first oil passage extends along the axial direction of the pile hanging body, the second oil passage extends along the radial direction of the pile hanging body, and the second oil passage communicates with the outer side wall of the pile hanging body to form an oil outlet hole.
[0010] Further, a straight-through oil cup is installed at the oil injection hole.
[0011] Further, there are two second oil passages. There is a distance between the two second oil passages and they are distributed perpendicular to each other.
[0012] Further, the installation sleeve is a steel pipe bushing.
[0013] Another object of the present utility model is to provide a container. The frame beam is one of a bottom longitudinal beam or a top longitudinal beam, and the retractable pile hanging device described in any one of the above is installed on the frame beam.
[0014] The beneficial effects of the present utility model are as follows:
[0015] For the pile hanging structure provided by the present utility model, when hoisting is required, the pile hanging body is extended outside the frame beam and then the hoisting wire rope can be used for installation and fixation. At this time, the second limiting plate on the inner side can prevent the pile hanging body from slipping out and falling off when being pulled by hoisting; the first limiting plate on the outer side can limit the hoisting wire rope; after hoisting, loading and unloading, and moving are completed, the pile hanging body is pushed inside the frame beam and can be hidden inside the container, which does not hinder the passage of personnel and reduces the outer contour width dimension of the product; the overall structure is simple and unique, the effect is reliable, and the functions of telescoping and limiting can be effectively realized.

[0023] The structure provided by the utility model will be explained and described in detail below with reference to the accompanying drawings of the specification.
[0024] Refer to Figures 1 to 4 As shown, this embodiment specifically discloses a telescopic pile hanging device, which is installed on the frame beam 1 of the container. The frame beam 1 can specifically be one of the bottom longitudinal beam or the top longitudinal beam, and it is generally a U-shaped steel structure. To enhance the structural strength of the frame beam 1, a reinforcing rib plate 2 is arranged on the outer side of the frame beam 1. In this embodiment, the telescopic pile hanging device includes an installation sleeve 3 and a pile hanging body 4. Through holes 11 for installing the installation sleeve 3 are provided on the frame beam 1 and the reinforcing rib plate 2. The installation sleeve 3 is fixedly installed in the through holes 11, and the pile hanging body 4 is movably arranged in the installation sleeve 3. One end of the pile hanging body 4 extends outward along the installation sleeve 3 to the outside of the frame beam 1 and is provided with a first limiting plate 5, and the other end of the pile hanging body 4 extends inward along the installation sleeve 3 to the inside of the frame beam 1 and is provided with a second limiting plate 6.
[0025] Specifically, when it is necessary to lift the container, the pile hanging body 4 can be extended out of the frame beam 1 and then the lifting wire rope can be used for installation and fixation. To ensure the safety of the force and increase the force-bearing area, the installation sleeve 3 is a circular steel pipe bushing; at this time, the inner second limiting plate 6 can prevent the pile hanging body 4 from sliding out and falling off when being lifted and pulled; the outer first limiting plate 5 can limit the lifting wire rope; after the lifting, loading, unloading, and moving are completed, the pile hanging body 4 can be pushed to the inside of the frame beam 1 and then hidden inside the container, which does not hinder the passage of personnel and reduces the outer contour width dimension of the product; the overall structure is simple and unique, and the effect is reliable, and the functions of telescoping and limiting can be effectively realized.
[0026] In some embodiments, the second limiting plate 6 and the pile hanging body 4 are of an integral forming structure, that is, the second limiting plate 6 can directly be a flange structure at one end of the pile hanging body 4; the first limiting plate 5 is detachably connected to the pile hanging body 4, and specifically can be connected by screws 7.
[0027] Among them, the pile hanging body 4 is of a stepped shaft structure, and the first limiting plate 5 is detachably connected to one side of the stepped surface of the pile hanging body 4.
[0028] During installation, the pile hanging body 4 can be directly inserted into the through hole from the inner side of the frame beam 1, and then the second baffle is installed and fixed with screws from the outside. In the illustrated embodiment, 2 socket head cap screws can be used for fixation to avoid the protrusion of the screws.
[0029] In some embodiments, an oil injection hole 41 is provided at the outer end of the pile hanging body 4, a first oil passage 42 communicating with the oil injection hole 41 and a second oil passage 43 communicating with the first oil passage 42 are provided inside. The first oil passage 42 extends along the axial direction of the pile hanging body 4, the second oil passage 43 extends along the radial direction of the pile hanging body 4, and the second oil passage 43 communicates with the outer wall of the pile hanging body 4 to form an oil outlet hole 44. By providing the oil injection hole 41, the first oil passage 42 and the second oil passage 43, lubricating oil can be filled into the interior via the oil injection hole 41, and after passing through the first oil passage 42 and the second oil passage 43, it flows out from the oil outlet hole 44, thereby reducing the sliding friction between the pile hanging body 4 and the installation sleeve 3.
[0030] Furthermore, in this embodiment, a straight-through oil cup 8 is installed at the oil injection hole 41. By providing the straight-through oil cup 8, it can be avoided that the lubricating oil flows out from the oil injection hole 41, the entry of pollutants during the oil filling process can be reduced, and the straight-through oil cup 8 can play an effect of uniform distribution, avoiding excessive lubrication caused by direct oil filling and reducing waste.
[0031] Combined Figure 3 and Figure 4 As shown, there are two second oil passages 43, there is a spacing between the two second oil passages 43, and they are perpendicularly distributed to each other. Correspondingly, there are also two oil outlet holes 44 formed. The two oil outlet holes 44 are spaced apart and perpendicularly distributed to each other, which can make the oil outlet more uniform during the left-right sliding process of the pile hanging body 4 and play a lubricating effect.
[0032] Furthermore, this embodiment also provides a container, which includes a frame beam 1. The frame beam 1 is one of the bottom longitudinal beam or the top longitudinal beam, and the retractable pile hanging device of any of the above embodiments is installed on the frame beam 1. In the container of this embodiment, by providing a retractable pile hanging device, it can be hidden into the container when not in use, reducing the overall contour size of the container, and there is a limit in both states, and the lifting effect is safe and reliable.
