Description

TECHNICAL FIELD

[0001] The utility model relates to a transfer port equipment transportation technical field, concretely relates to a cushion beam for being arranged between the module car and the joist of transfer port equipment. BACKGROUND

[0002] In the whole process cycle of the sea transportation of the whole rail-mounted gantry container crane (referred to as: rail-mounted crane) and other port equipment, the self-propelled modular flat car (referred to as: module car or SPMT) is widely used for the loading and unloading of ships and transfer operations of the rail-mounted crane. Because the weight of the rail-mounted crane is large, directly acting on the module car will cause a large stress concentration to the bearing structure of the module car, affecting its service life and safety. Therefore, the joist is used to connect the rail-mounted crane and the module car. However, in the process of using the joist for the loading and unloading of ships and transfer operations of the rail-mounted crane, the following significant problems exist:

[0003] Firstly, the overall size of the joist is large and the self-weight is heavy, which makes it necessary to use a large truck crane to complete the loading and unloading of ships and transfer operations of the rail-mounted crane. This dependence not only increases the complexity and cost of operation, but also significantly reduces the work efficiency. Because the operation of the large truck crane takes a long time, and in some site conditions, there may not be enough space or ground bearing capacity to support its operation, thus limiting the flexibility and adaptability of the operation.

[0004] Secondly, the existing joist structure lacks a quick installation and disassembly mechanism, and a large amount of time and manpower is required for each installation and disassembly, which cannot meet the needs of efficient operation.

[0005] Finally, the existing joist structure usually only has a single function, which leads to the need for additional equipment or tools to complete other related operations in different application scenarios, further increasing the cost of equipment and the complexity of operation.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0047] The pad beam 100 according to an embodiment of the present utility model will now be described in detail with reference to the accompanying drawings.

[0048] like Figures 1 to 5 As shown, the pad beam 100 according to an embodiment of the present utility model is used to be installed between the module vehicle 300 and the support beam 200 of the transfer port equipment, and may include: a transverse support 1 and two sets of columns 2.

[0049] Specifically, the length direction of the transverse support 1 is consistent with the width direction of the joist 200, and the transverse support 1 is used to support the bottom of the joist 200. The two groups of columns 2 are respectively detachably connected at the two ends of the length direction of the transverse support 1. Among them, the lower part of the transverse support 1 and the two groups of columns 2 form a walking space 3 for the module vehicle 300 to pass through.

[0050] As shown in Figures 1 to 5 the track crane and other port equipment are shipped, unloaded and transferred on the wharf ground 500, a plurality of position of the length direction of the joist 200 can be provided with the cushion beam 100 provided by the application to support the joist 200. The cushion beam 100 of the application supports the bottom of the joist 200 through the transverse support 1, and the length direction of the transverse support 1 is consistent with the width direction of the joist 200, so that the plurality of cushion beams 100 can uniformly distribute the weight of the joist 200 when supporting. The two groups of columns 2 are respectively detachably connected at the two ends of the length direction of the transverse support 1, forming a stable support frame. When the joist 200 is placed in the rear field, the cushion beam 100 of the application can also be used as a cradle, reducing the dependence on additional equipment and reducing equipment cost and operation complexity. Each group of columns 2 can be one or more, which is adaptively selected according to the site conditions. The module vehicle 300 directly passes through the walking space 3 formed between the transverse support 1 and the two groups of columns 2 during the track crane loading and unloading or transfer process, and the module vehicle 300 only uses its own lifting stroke to lift the joist 200 and the cushion beam 100 under the joist 200 in the walking space 3, that is, the loading and unloading of the joist 200 on the module vehicle 300 can be completed, avoiding the dependence on large truck cranes, simplifying the installation and disassembly process, and improving the work efficiency.

[0051] When the module vehicle 300 lifts the cushion beam 100 and the joist 200, the columns 2 at the two ends of the transverse support 1 can be removed to provide more operating space for the module vehicle 300 in some narrow spaces, so that the module vehicle 300 can more easily complete the disassembly or transfer operation of the joist 200, and reduce the potential collision risk. Moreover, the columns 2 and the transverse support 1 adopt detachable connectors 6 (such as bolts, pins, etc.), so that the transverse support 1 and the columns 2 can be transported separately, simplifying the logistics cost, and the columns 2 and the transverse support 1 can be removed and reinstalled in a short time at the operation site, thereby speeding up the entire loading and unloading process.

[0052] In some embodiments of the present application, as shown in Figure 1 the transverse support 1 is a hollow plate structure, and the transverse support 1 can include a first transverse plate 11, a second transverse plate 12 and two side plates 13.

[0053] Specifically, the first transverse plate 11 and the second transverse plate 12 are arranged in parallel and the length direction of the first transverse plate 11 and the second transverse plate 12 is consistent with the width direction of the joist 200, the first transverse plate 11 is located above the second transverse plate 12, the upper surface of the first transverse plate 11 is used for supporting the bottom of the joist 200, and the two groups of stand columns 2 are detachably connected with the second transverse plate 12.

[0054] In some embodiments of the utility model, as shown in Figure 1 The transverse support 1 can further include two first reinforcing rib plates 14 and a plurality of second reinforcing rib plates 15.

[0055] Specifically, the two first reinforcing rib plates 14 are respectively located above the two groups of stand columns 2 and between the first transverse plate 11 and the second transverse plate 12, the upper surfaces of the two first reinforcing rib plates 14 are respectively connected with the first transverse plate 11 and the lower surfaces thereof are respectively connected with the second transverse plate 12. The plurality of second reinforcing rib plates 15 are respectively located between the two first reinforcing rib plates 14 and between the first transverse plate 11 and the second transverse plate 12, the upper surfaces of the plurality of second reinforcing rib plates 15 are respectively connected with the first transverse plate 11 and the lower surfaces thereof are respectively connected with the second transverse plate 12. Wherein, each first reinforcing rib plate 14 and each second reinforcing rib plate 15 are respectively perpendicular to the first transverse plate 11 and extend along the width direction of the first transverse plate 11. Thus, by arranging the first reinforcing rib plate 14, the rigidity and the carrying capacity of the key area of the transverse support 1 near the stand column 2 at both ends are effectively enhanced, and local deformation or damage is prevented. Similarly, by arranging the second reinforcing rib plate 15, the second reinforcing rib plate 15 is uniformly distributed between the first transverse plate 11 and the second transverse plate 12, which provides additional support and rigidity for the transverse support 1 supporting the joist 200, and ensures that the entire transverse support 1 will not be twisted or deformed during the transfer process. Moreover, the first reinforcing rib plate 14 and the second reinforcing rib plate 15 improve the overall structural strength of the cushion beam 100, and due to the reasonable design, the overall weight is not significantly increased.

[0056] In some embodiments of the utility model, as shown in Figure 1 The cushion beam 100 can further include a plurality of adjusting blocking frames 4. The adjusting blocking frame 4 corresponds to the stand column 2 one by one, each adjusting blocking frame 4 is arranged below the second transverse plate 12 and located on the side of the corresponding stand column 2 close to the walking space 3, and each adjusting blocking frame 4 is detachably connected with the corresponding stand column 2 and the second transverse plate 12.

[0057] Each of the adjusting baffle 4 can include a first connecting plate 41 and a second connecting plate 42 connected perpendicularly to each other, the first connecting plate 41 is detachably connected with the second transverse plate 12 in parallel, the second connecting plate 42 is detachably connected with the corresponding column 2 in parallel, one end of the first connecting plate 41 close to the corresponding column 2 is connected with the top of the second connecting plate 42, forming a stable L-shaped support structure. The design of the adjusting baffle 4 provides additional support points for the transverse support 1 and the corresponding column 2 connected thereto, and enhances the stability and safety of the cushion beam 100 in use. The transverse support 1, the column 2 and the adjusting baffle 4 are connected through detachable connectors 6 (such as bolts, nuts, washers, etc.), the installation and disassembly time is short, which is conducive to improving the work efficiency on site.

[0058] In some embodiments of the utility model, as shown in Figure 1 Each of the adjusting baffle 4 can further include a connecting inclined plate 43 connected with the corresponding first connecting plate 41 and second connecting plate 42 respectively. Therefore, the design of the connecting inclined plate 43 further enhances the structural rigidity and stability of the adjusting baffle 4, and provides additional support and anti-deformation capability.

[0059] In some embodiments of the utility model, as shown in Figures 1 to 2 The first connecting plate 41 is provided with a first adjusting long hole (not shown) corresponding to the second transverse plate 12, the first adjusting long hole extends along the length direction of the first transverse plate 11 and penetrates the first connecting plate 41 in the vertical direction.

[0060] That is, by providing the first adjusting long hole on the first connecting plate 41, the first connecting plate 41 is allowed to be finely adjusted in the length direction of the first transverse plate 11, ensuring that the first connecting plate 41 is connected with the second transverse plate 12, and improving the stability and safety of the overall structure.

[0061] In some embodiments of the utility model, as shown in Figures 1 to 2 The second connecting plate 42 is provided with a second adjusting long hole (not shown) corresponding to the corresponding column 2, the second adjusting long hole extends in the vertical direction and penetrates the second connecting plate 42 in the direction perpendicular to the second connecting plate 42.

[0062] Similarly, by providing the second adjusting long hole on the second connecting plate 42, the second connecting plate 42 is allowed to be finely adjusted in the vertical direction, ensuring that the column 2 is connected with the second connecting plate 42, and enhancing the stability of the overall structure.

[0063] It should be noted that the positions of the first and second adjustment elongated holes are flexible. For example, the first adjustment elongated hole can also be located on the second horizontal plate 12, and the second adjustment elongated hole can also be located on the side of the column 2 near the walking space 3. The specific positions can be adjusted according to the operational needs on site.

[0064] In some embodiments of this utility model, such as Figures 1 to 2 As shown, the upper surface of the transverse support 1 is also provided with a retaining member 5, which is used to hold the support beam 200 to prevent it from loosening and shifting during transportation.

[0065] In some embodiments of this utility model, such as Figures 1 to 2 As shown, the retaining member 5 may include two first wedge plates 51 and two second wedge plates 52.

[0066] Specifically, two first wedge plates 51 are symmetrically arranged along the length of the transverse support 1. Each first wedge plate 51 is welded to the upper surface of the transverse support 1. The support beam 200 is located between the two first wedge plates 51, and the ends of the two first wedge plates 51 that are close to each other respectively form a first slope surface. Two second wedge plates 52 are respectively used to embed between the corresponding first wedge plate 51 and the support beam 200 to lock the support beam 200. Each second wedge plate 52 is provided with a second slope surface that matches its corresponding first slope surface.

[0067] The following is combined Figures 1 to 2 Briefly describe the working process of card holder 5:

[0068] First, the support beam 200 is placed on the upper surface of the transverse support 1, specifically between the two first wedge plates 51. Then, the second slope surfaces of the two second wedge plates 52 are respectively inserted into the gaps between the first wedge plates 51 and the support beam 200 along the first slope surfaces of their corresponding first wedge plates 51. Thus, the support beam 200 is locked in place by the frictional force of the slope surfaces.

[0069] In some embodiments of this utility model, such as Figures 1 to 5 As shown, each column 2 has a base plate 21 at its bottom. On the side of the base plate 21 away from the walking space 3, there is a diagonal brace 22 connected to the column 2. The diagonal brace 22 also has a shackle mounting hole 23. One end of the wire rope 400 can be connected to the shackle mounting hole 23 through a shackle, and the other end of the wire rope 400 can be connected to the corresponding position of the support beam 200.

[0070] Specifically, the bottom of each column 2 is provided with a bottom plate 21, which provides a larger contact area, increases the friction between the column 2 and the ground, and thus improves the stability of the column 2 support. The inclined bracing plate 22 further provides an additional support point, enhancing the structural strength and overturning resistance of the column 2. The inclined bracing plate 22 is also provided with a shackle mounting hole 23, one end of the steel wire rope 400 is connected with the shackle mounting hole 23 through a shackle (not shown), and the other end of the steel wire rope 400 is connected with the corresponding position of the joist 200. Thus, on the basis of the clamping piece 5, additional tension support is further provided, enhancing the stability of the structure and preventing the joist 200 from shifting or overturning during transportation.

[0071] Based on the above embodiments of the present application, one technical feature of one embodiment can be beneficially combined with one or more other embodiments without explicit negation or conflict.

[0072] The above is the preferred embodiment of the present application, it should be pointed out that for those skilled in the art, without departing from the principles of the present application, can make a number of improvements and refinements, these improvements and refinements should also be considered as the protection scope of the present application.
