Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of transport trolleys, and particularly to a marine large spare part moving device. Background Art
[0002] With the development of ship technology, there are more and more ship supporting equipment. In order to increase the cargo capacity as much as possible, the engine room space is generally relatively compact. For medium and small ships, the engine room structure is narrow, but there are many equipment, large and numerous pipes, and in addition to outfitting parts such as cables and iron outfittings, which makes the engine room layout difficult. If the layout is not good, it will lead to problems such as difficult equipment maintenance, increasing the work difficulty of shipyard construction workers and crew.
[0003] The large spare parts of ship equipment are relatively heavy, especially the spare parts of the main engine or generator set, which are difficult to move by manpower. It is best that they can be arranged within the coverage of the equipment traveling crane during ship design, which can reduce the difficulty of replacing large spare parts. However, on some medium and small ships, due to space limitations, large spare parts cannot be arranged within the lifting range of the equipment traveling crane. When this situation occurs, the large spare parts can only be arranged outside the lifting range of the equipment traveling crane, and consideration should be given to how to move them to the lifting range of the equipment traveling crane when replacing large spare parts. At present, it is difficult for the transport trolley to load large spare parts over the threshold and go up and down slopes, resulting in a relatively high difficulty in arranging large spare parts. Summary of the Invention
[0004] The purpose of the present invention is to provide a marine large spare part moving device, which reduces the difficulty of arranging large spare parts and facilitates the transportation of large spare parts across the threshold.
[0005] To achieve the above object, the present invention provides a marine large spare part moving device, including:
[0006] A first trolley, including a first flat plate, a directional wheel set and a seat frame.

[0011] In some embodiments, each second trolley includes two chutes. The first trolley is provided with two sets of directional wheel groups, and the two sets of directional wheel groups are respectively slidably connected to the two chutes.
[0012] In some embodiments, the depth of the chute is a, and the diameter of the pulley of the directional wheel group is b, then 0.2b ≤ a ≤ 0.4b is satisfied.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.
[0030] It should be understood that in the description of the present application, the orientation or positional relationship indicated by terms such as "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application. The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. That is, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In addition, unless otherwise specified, the meaning of "a plurality" is two or more.
[0031] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.
[0032] As Figures 1 - 6 shown, a marine large spare part moving device according to some embodiments of the present invention includes: a first trolley 1 and a second trolley 2. The first trolley 1 includes a first flat plate 11, a directional wheel set 12 and a seat frame 13. The directional wheel set 12 is connected to the bottom surface of the first flat plate 11, and the seat frame 13 is installed on the surface of the first flat plate 11. The seat frame 13 is used for installing a large spare part 3. The second trolley 2 includes a second flat plate 21, a universal wheel set 22, a chute 23 and a handrail 24. The chute 23 is provided on the surface of the second flat plate 21, and the directional wheel set 12 is slidably connected to the chute 23. The universal wheel set 22 is connected to the bottom surface of the second flat plate 21.
[0033] As Figure 4 shown, in this embodiment, the moving device has a transportation state or a straddle state; when the moving device is in the transportation state, there is one second trolley 2, and the handrail 24 is detachably connected to the first flat plate 11 and the second flat plate 21 respectively. In this way, the positions between the first trolley 1 and the second trolley 2 are stable, and the large spare part 3 in the flat state is used for transportation.
[0034] As Figures 1 - 3 shown, in this embodiment, when the moving device is in the straddle state, there are two second trolleys 2. The second flat plates 21 of the two second trolleys 2 are detachably connected through a fixing plate 25. The two handrails 24 are respectively installed at the ends of the two second flat plates 21. The first trolley 1 slides along the chute 23 of one second trolley 2 to the chute 23 of the other second trolley 2. At this time, the two second trolleys 2 are respectively located on both sides of the threshold. In this way, when the first trolley 1 slides along the chute 23 of one second trolley 2 to the chute 23 of the other second trolley 2, the large spare part 3 can smoothly cross the threshold.
[0035] AsFigure 6 As shown, in some embodiments, each second trolley 2 includes two sliding grooves 23, and the first trolley 1 is provided with two sets of directional wheel groups 12. The two sets of directional wheel groups 12 are slidably connected to the two sliding grooves 23 in a one-to-one correspondence. In this way, the first trolley 1 can slide straight on the second trolley 2 smoothly.
[0036] In some embodiments, the depth of the sliding groove 23 is a, and the diameter of the pulley of the directional wheel group 12 is b, then 0.2b ≤ a ≤ 0.4b is satisfied. If a < 0.2b, the depth of the sliding groove 23 is too small, making the directional wheel group 12 easy to slide out of the sliding groove 23. If a > 0.4b, the depth of the sliding groove 23 is too large, increasing the sliding friction of the directional wheel group 12 and making the sliding not smooth.
[0037] As Figures 1 - 3 shown, in some embodiments, the fixing plate 25 is made of angle steel, and the fixing plate 25 is respectively connected to the sides of the two second flat plates 21 through the first bolts 251. In this way, the installation structure between the two second flat plates 21 is kept firm and the disassembly is convenient.
[0038] In some embodiments, the armrest 24 is connected to the side of the first flat plate 11 through the second bolt 241. In this way, the installation structure of the armrest 24 on the side of the first flat plate 11 is firm and the disassembly is convenient.
[0039] In some embodiments, the armrest 24 is connected to the side of the second flat plate 21 through the third bolt 242. In this way, the installation structure of the armrest 24 on the side of the second flat plate 21 is firm and the disassembly is convenient.
[0040] As Figure 4 shown, in some embodiments, when there is one second trolley 2, there are two armrests 24, and the two armrests are respectively detachably connected to the first flat plate 11 and the second flat plate 21. In this way, the second trolley 2 can be pushed from both sides through the armrests 24.
[0041] As Figures 1 - 3 shown, in some embodiments, when there are two second trolleys 2, the two second trolleys 2 are symmetrically distributed in the height direction. One armrest 24 is installed at one end of one second flat plate 21 away from the other second flat plate 21, and the other armrest 24 is installed at one end of the other second flat plate 21 away from the one second flat plate 21. That is, the armrests 24 on both sides are located outside the two second trolleys 2 and will not block the sliding of the first trolley 1.
[0042] In some embodiments, the sliding grooves 23 on the two second flat plates 21 are in the same straight line and communicate with each other. In this way, the smooth sliding of the first trolley 1 can be maintained. It should be noted that, for safety reasons, baffles are installed outside the sliding grooves 23 to prevent the first trolley 1 from sliding out of the second flat plate 21 of the second trolley 2 from the sliding grooves 23.
[0043] In some embodiments, the length of the first flat plate 11 is equal to the length of the second flat plate 21, and the width of the first flat plate 11 is equal to the width of the second flat plate 21. In this way, the structure is kept regular, facilitating the combined installation of the first trolley 1 and the second trolley 2.
[0044] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
