Description

Technical Field

[0001] The utility model relates to the technical field of container repair, and more specifically, to a container repair mechanism. Background Art

[0002] When inspecting containers, it will be found that the relative position deviation of some parts is too large. For example, the size of the door gap exceeds the standard, resulting in the strips failing to seal, causing the box's outer dimensions to exceed the standard or the door panel strips to leak. It is necessary to immediately check and correct the size and uniformity of the door gap, check and correct the welding deformation of the door panel or door frame, and check and correct the diagonal of the container.

[0003] In order to carry out inspection and correction work, a positioning reference must be set up, and it is best to be equipped with an operating platform that is easy to inspect and maintain. However, modern container manufacturing is done through intermittent production lines, and some additional positioning references or operating platforms will affect the transportation of containers.

[0004] Therefore, in order to place the container on the benchmark, it is often necessary to use a crane or monorail crane for lifting. During the operation, the worker first climbs to the top of the container through a ladder, hangs hooks on the four top corner pieces of the container, and then leaves the original way, removes the corner wheels of the container, and then lifts the container to a nearby positioning platform, and then manually straightens it. After the inspection is completed, the lifting steps are repeated, the corner wheels are installed, and the container is lifted back to its original position. The worker climbs to the top of the container to remove the hook. The operation is time-consuming and laborious. The container sways and shakes when suspended in the air, and the safety is low. A large number of special equipment such as cranes are required, which is costly. The movement is slow and the operation is repeated, which seriously affects the production cycle and has low efficiency. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a container repair mechanism to solve one or more of the above-mentioned problems.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] The container repair mechanism comprises a transverse chain mechanism laid on the ground, on which a container is carried, and on which four corners of the container are provided with corner wheels, and in the gaps of the transverse chain mechanism at least four transversely symmetrical and sunken lifting stations are provided, in each of which a hydraulic lift is provided, on which a longitudinally movable adjustment trolley is provided, and positioning platforms are provided on the ground at both longitudinal ends of the lifting stations.

[0008] Furthermore, a trolley track is provided on the top of the hydraulic lift, and the running wheels of the adjustment trolley are arranged on the trolley track.

[0009] Furthermore, a trolley cylinder is provided on the top of the hydraulic lift, and the movable end of the trolley cylinder is connected to the adjustment trolley, and the trolley cylinder drives the adjustment trolley to slide along the trolley track.

[0010] Furthermore, a stopper is provided at the end of the trolley track, and the maximum stroke of the adjustment trolley is 500-600 mm.

[0011] Furthermore, a longitudinal chain mechanism is also provided at the end of the transverse chain mechanism, and the longitudinal chain mechanism drives the container to leave the transverse chain mechanism through a hook chain.

[0012] In summary, the utility model has the following beneficial effects: the container is transported and lifted by cooperating with the transverse chain mechanism and the hydraulic lift, avoiding the use of special lifting equipment and reducing the cost of equipment use; facilitating continuous operation and ensuring the normal production rhythm; the container is supported by the hydraulic lift and will not be completely suspended, and will not shake, which is safer; there is no need for workers to climb up and down to cooperate with the lifting, and the maintenance efficiency is higher.

[0024] The following is combined with Figure 1 -10 further describes the utility model in detail.

[0025] Example:

[0026] Pre-set the channel in the maintenance workshop, such as Figure 6 As shown, three parallel and equally spaced transverse chain accommodating channels are preset in the transverse direction, and a special driving mechanism pit is set at the rear end. Four lifting stations 2 are preset separately, and the lifting station 2 is set between two adjacent transverse chain accommodating channels. The position setting of the lifting station 2 needs to ensure that there is a longitudinal movement margin when the subsequent container is transferred from the transverse chain mechanism 2 to the positioning platform 3. This design is not simply to adjust the trolley 5 to be able to move longitudinally, but to ensure that the container can be transported smoothly. The overall movement route of the positioning platform 3 and the transverse chain mechanism 1 is staggered, and the longitudinal movement of the trolley 5 is adjusted to make up for this longitudinal difference. The four lifting stations 2 are divided into two groups, and the two groups of lifting stations 2 are aligned in the transverse direction, and the two lifting stations 2 in each group are aligned in the longitudinal direction. Preferably, a longitudinal chain accommodating channel is opened in the longitudinal direction at the front and rear ends of the transverse chain channel, which is used for the later laying of the longitudinal chain mechanism, and the overhauled container is taken out of the transverse chain mechanism 1 through the hook chain, and sent out of the overhaul workshop in the longitudinal direction or the unoverhauled container is sent to the overhaul workshop.

[0027] Container repair organizations, such as Figure 1 As shown, it is mainly composed of four lifting stations 2 with hydraulic lifts 4, a transverse chain mechanism 1, and four positioning platforms 3. The depth of the lifting station 2 needs to ensure that when the hydraulic lift 4 is in the retracted state after being set, the entire equipment is in the lowest height state, only the top adjustment trolley 5 is slightly higher than the ground, and most of the hydraulic lift 4 is accommodated in the pit.

[0028] A transverse chain mechanism 1 is installed in the transverse chain accommodating channel. The transverse chain is divided into three walkways, which are recorded as transverse chain walkway No. 1a, transverse chain walkway No. 2b and transverse chain walkway No. 3c from left to right. Four lifting stations 2 are respectively arranged between transverse chain walkway No. 1a and transverse chain walkway No. 2b, and between transverse chain walkway No. 2b and transverse chain walkway No. 3c. A special set of positioning platforms 3 is arranged on the ground beside the lifting station 2 at both ends of the longitudinal direction. Each set of positioning platforms 3 includes two symmetrically arranged I-shaped steel positioning frames, and the two positioning frames are longitudinally aligned. After the four corners of the container are installed with box corner wheels, they are placed on two of the transverse chains for transportation. The height of the positioning frame and the upright height of the box corner wheel should ensure that the container will not collide with the positioning frame during movement, and the relevant difference should not be too large.

[0029] Each lifting station 2 is provided with a hydraulic lift 4, and a longitudinally movable adjustment trolley 5 is provided at the top of the hydraulic lift 4. Specifically, a longitudinal trolley track is laid on the top of the hydraulic lift 4, and a plurality of wheels are provided at the bottom of the adjustment trolley 5. The wheels of the adjustment trolley 5 are arranged on the trolley track. The arrangement here refers to the grooves provided on the wheel body surface of the wheel to dock with the trolley track, and the two sides of the grooves form an embedded structure with the trolley track to ensure that the adjustment trolley 5 will not deviate laterally, but will not affect the linear sliding of the adjustment trolley 5 along the trolley track. A trolley cylinder is also provided on the top of the hydraulic lift 4, and the movable end of the trolley cylinder is connected to the adjustment trolley 5, and the trolley cylinder drives the adjustment trolley 5 to slide longitudinally along the trolley track. A block is provided at the right end of the trolley track, and the position of the block is related to its maximum stroke, which is 500-600mm. Preferably 500mm.

[0030] The four lifting stations 2 are marked in the order from right to left and from bottom to top, and are recorded as station 1 21, station 22, station 3 23 and station 4 24. Station 1 21 and station 3 23 are arranged between the second transverse chain walkway 1b and the third transverse chain walkway 1c, and station 22 and station 4 21 are arranged between the first transverse chain walkway 1a and the second transverse chain walkway 1b, and are arranged to the right of the symmetry center of the two transverse chain walkways, leaving a margin for adjusting the longitudinal movement of the trolley 5.

[0031] There are two main possible approaches:

[0032] There are different ways of using it for different container sizes:

[0033] Extra-long containers, such as side-opening containers and folding containers, use Figure 2 and Figure 3As shown, the two longitudinal lifting stations 2 are combined as a combined station, the No. 1 station 21 and the No. 2 station 22 are combined, and the No. 3 station 23 and the No. 4 station 24 are combined. At this time, the two outermost transverse chain walkways, namely the No. 1 transverse chain walkway 1a and the No. 3 transverse chain walkway 1c, are used to transport containers, and at most two containers can be inspected at the same time. The head and tail ends of the extra-long container leave the ground through the box corner wheels, align on the two transverse chain walkways, and are transported to the top of the one-two combined station or the three-four combined station through the transverse chain mechanism 1. Taking the one-two combined station as an example, the hydraulic lift 4 is as shown at this time. Figure 7 As shown, it is in the retracted state. The hydraulic lifts 4 of the No. 1 station 21 and the No. 2 station 22 are raised synchronously, and the state is as follows Figure 8 As shown, it contacts the bottom of the container and continues to rise until the top of the hydraulic lift 4 completely lifts the container, the corner wheels and the container leave the transverse chain mechanism 1, and the corner wheels installed on the container automatically fall off. The corresponding trolley cylinders operate synchronously to push the adjustment trolley 5. At this time, the state of the hydraulic lift 4 is as follows Fig. 9 As shown, the trolley 5 is adjusted to move the container to the right by 500 mm, and the end of the container comes to the left side of the positioning frame of the second station 22 and the right side of the positioning frame of the first station 21, and the other two positioning frames are aligned with the middle section of the container. The hydraulic lift 4 starts to fall, and the state at this time is as follows: Fig.10 As shown, until the container is fixed on the corresponding positioning platform 3. The workers start to inspect and repair. After the inspection is completed, the hydraulic lift 4 lifts the container, the container leaves the positioning platform 3, the corner wheels are installed, and the trolley cylinder pushes the adjustment trolley 5 in the reverse direction, carrying the container to move 500mm in the reverse direction synchronously, and the corner wheels return to the top of the transverse chain mechanism 1, and the hydraulic lift 4 continues to descend to ensure that the adjustment trolley 5 leaves the container, and the container leaves with the transverse chain mechanism 1 and leaves the maintenance workshop with the help of the longitudinal chain mechanism.

[0034] The operation of regular size containers is relatively simple, such as Figure 4 and Figure 5As shown, the system can inspect and repair two containers at most at the same time. Generally, workstation No. 1 21 and workstation No. 3 23 are used, and workstation No. 2 22 and workstation No. 4 24 are idle, because there are only three transverse chain walkways, and only two of them can be used at the same time. Taking workstation No. 1 21 as an example, using transverse chain walkway No. 2 1b and transverse chain walkway No. 3 1c, the container is transported to the top of workstation No. 1 21 through the transverse chain mechanism 1, and the hydraulic lift 4 of workstation No. 1 21 is lifted, contacts the top of the container and continues to lift until the corner wheels of the container leave the transverse chain mechanism 1, and the corner wheels automatically fall off. The trolley cylinder operates to drive the adjustment trolley 5 to the right 500mm, and the container is synchronously driven to the top of the two placement racks of workstation No. 1 21. The hydraulic lift 4 falls, and the container is set and fixed on the positioning platform 3, and the inspection begins. After the inspection is completed, the hydraulic lift 4 is lifted off the positioning platform 3, and the container corner wheels are installed. The container is driven in the opposite direction for 500 mm to the top of the transverse chain mechanism 1, and then driven by the hydraulic lift 4 to drop down, ensuring that the adjustment trolley 5 leaves the container and leaves the inspection workshop along with the transverse chain mechanism 1 and the longitudinal chain mechanism.

[0035] It should be noted that this specific embodiment is merely an explanation of the present utility model, and it is not a limitation of the present utility model. After reading this specification, those skilled in the art can make non-creative modifications to the present embodiment as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
