Description

Technical Field

[0001] This invention relates to trailer systems, methods for moving objects using trailer systems, and trailer jack systems. Background Technology

[0002] Modular trailer systems, such as self-propelled modular trailer systems, are known to be used for transporting large and / or heavy objects, such as pipe racks, bridge decks, or buildings. A modular trailer system may include multiple trailer modules. Each trailer module includes multiple wheels, which in many cases can be individually controlled, allowing the trailer module to move on a surface in any desired direction, including lateral movement and movement about its own central axis. Each trailer module further includes a loading bed for supporting the object to be moved. The object can be placed directly on the loading bed and / or supported by object supports, which in turn are supported by the loading bed. Trailer modules can be connected to each other in the longitudinal and / or lateral directions to obtain a combined loading bed larger than the loading beds of individual trailer modules. The combined loading bed is rigid to maintain load stability. Therefore, for example, the loading beds of individual modules are not hinged relative to each other. This is also unnecessary, as the wheels of a trailer module can typically be individually controlled and rotated independently about both the horizontal and vertical axes. Trailer modules can also be used individually when the size and weight of the object to be transported permits.

[0003] To pick up an object to be transported, a loading bed of a trailer module, or a combined loading bed of multiple interconnected trailer modules, is positioned beneath the object. The object may need to be lifted and placed on temporary ground supports to achieve this. The object is then lowered onto the loading bed or onto loading bed supports of one or more trailer modules to prepare for transport. Loading bed supports can be static or movable, for example, in the form of jacks. In some designs, the loading bed of a trailer module can move vertically within a limited travel range (e.g., 600 mm). In this case, the loading bed can be moved upwards to a limited extent to lift the object away from the temporary ground supports, so that the object can be fully supported on the loading bed of one or more trailer modules, and the temporary ground supports can be removed.

[0004] This method typically requires significant time, manpower, and materials, particularly support materials. The large amount of materials required means more cargo needs to be transported to the object's location, increasing CO2 emissions from the transport project. Furthermore, when loading bed supports are required, this increases the overall height of the trailer system, necessitating more free space beneath the object to accommodate the trailer modules. Additionally, when the object must be joined at a considerable height, it can affect the stability of the trailer system due to the resulting high center of gravity. Summary of the Invention

[0005] The purpose of this invention is to provide a trailer system that limits the need for high loading bed supports on the loading bed of the trailer module.

[0006] The objective of this invention is achieved by a trailer system comprising:

[0007] - A first trailer module, comprising:

[0008] - Multiple wheels

[0009] - Loading bed,

[0010] - A main loading bed connector for rigidly connecting the loading bed of a first trailer module to the loading bed of another trailer module to form a combined rigid loading bed. The main loading bed connector is disposed below the upper surface of the loading bed of the first trailer module.

[0011] - A first jack system, including a first jack bracket, the first jack bracket comprising:

[0012] - Jack retainer and jack housed in jack retainer

[0013] - The main bracket connector, which is connected to the main loading bed connector of the first trailer module, and thereby connects the first jack bracket to the first trailer module.

[0014] The jack retainer of the first jack bracket extends at least partially below the upper surface of the loading bed of the first trailer module.

[0015] The trailer system according to the invention includes a first trailer module. The first trailer module is, for example, a trailer module of a self-propelled modular trailer system, or a trailer module that can be attached to a truck.

[0016] The first trailer module includes multiple wheels. Optionally, at least some wheels, and optionally all wheels, are rotatable about a horizontal axis and can also pivot or rotate about a vertical axis. Optionally, the position of each wheel about its vertical axis of rotation can be individually controlled, enabling the first trailer module to move in all directions on its surface. Optionally, the rotational speed of each wheel about its horizontal axis of rotation can be individually controlled. Optionally, the wheels are grouped in pairs, and the rotation of each pair of wheels about the horizontal and / or vertical axes is controlled.

[0017] In a variation of the invention, the first trailer module includes one or more sets of wheels provided with one or more tracks.

[0018] The first trailer module further includes a loading bed. The object to be transported is to be placed directly on the loading bed or on a loading bed support, which is positioned on the loading bed. The loading bed has an upper surface.

[0019] The first trailer module further includes a main loading bed connector for rigidly connecting the loading bed of the first trailer module to the loading bed of the other trailer module to form a combined rigid loading bed. The main loading bed connector is disposed below the upper surface of the loading bed of the first trailer module.

[0020] To implement this invention, the first trailer module does not need to be connected to another trailer module.

[0021] The trailer system according to the invention further includes a first jack system. The first jack system includes a first jack bracket.

[0022] The first jack bracket includes a jack retainer and a jack. The jack is housed in the jack retainer.

[0023] The jack bracket further includes a main bracket connector, which is connected to the main loading bed connector of the first trailer module. Thus, the main bracket connector connects the first jack bracket to the first trailer module. Therefore, in other uses of the first trailer module, a connector provided on the first trailer module for connecting the first trailer module to another trailer, according to the invention, is used instead to connect the first trailer module to the first jack bracket.

[0024] According to the invention, the jack retainer of the first jack bracket extends at least partially below the upper surface of the loading bed of the first trailer module. Optionally, the jack retainer of the first jack bracket extends completely below the upper surface of the loading bed of the first trailer module.

[0025] Optionally, the jack retainer extends at least partially below the main bracket connector. Optionally, the jack retainer extends entirely below the main bracket connector.

[0026] Optionally, the jack extends at least partially below the upper surface of the loading bed of the first trailer module and / or below the main bracket connector. Optionally, the jack extends entirely below the upper surface of the loading bed of the first trailer module and / or below the main bracket connector.

[0027] Alternatively, the jacks of the jack system may be or form part of a jack as disclosed in NL1042448.

[0028] Optionally, the loading bed of the first trailer module has a long side and a short side, and the first jack system is connected to the short side of the loading bed. Optionally, the first jack system does not extend beyond the width of the loading bed of the first trailer module to which it is connected, so the width of the first jack system extends entirely between the first longitudinal end and the second longitudinal end (opposite to the first longitudinal end) of the short side of the loading bed of the first trailer module. The first jack system may extend above and / or below the short side of the loading bed of the first trailer module. Optionally, the first jack bracket does not extend beyond the width of the loading bed of the trailer module to which it is connected. Therefore, the width of the first jack bracket extends entirely between the first longitudinal end and the second longitudinal end (opposite to the first longitudinal end) of the short side of the loading bed of the first trailer module. The first jack bracket may extend above and / or below the short side of the loading bed of the first trailer module.

[0029] The trailer system according to the invention allows for the transport of objects both vertically (via jacks) and horizontally (via trailer modules on their wheels) without having to switch from one support position on the object to another. This is advantageous, for example, for long and flexible objects such as pipe racks. The number of positions where they can be effectively supported is limited, so there is no need to move from one support position to another; all available support positions can be used.

[0030] Furthermore, the trailer system according to the invention features a compact design. By integrating the jack system into the trailer system, it is unnecessary to arrange separate jacks on the loading bed, which allows for a reduction in the height of the trailer system. The jack system is positioned at a level lower than the loading bed, so even when extending above the upper surface of the loading bed, its extension is less than that when the jack system is mounted on the loading bed (as is done in the prior art). This compact arrangement eliminates the need to raise the object to be transported to a high level and support it at that high level before arranging the trailer module below the object.

[0031] Furthermore, arranging the jacks in brackets extending below the trailer's loading bed allows the object to be supported at a level close to the loading bed during transport. This increases the stability of the object and the trailer system during transport.

[0032] The transport of large and / or heavy objects requires design on a case-by-case basis. The object's structure must be considered: where is the center of gravity, how flexible or rigid is the object, and which parts of the object can withstand what level of mechanical load? Then, it can be determined how to assemble the modules of the trailer system to transport the object safely. The mechanical characteristics of the trailer system, such as the forces, moments, and torques that the loading beds of the trailer modules can withstand, and the pressure on the individual wheels, play a crucial role in this. If multiple trailer modules are connected to each other, the loading beds of these modules must act as a single, rigid loading bed; therefore, in particular, moments and torques must be transferred from one trailer module's loading bed to another. However, the mechanical loads borne by the main loading bed connector when it connects one loading bed to the loading bed of another trailer module are entirely different from the mechanical loads borne by the main loading bed connector when it supports the jack system. The jack system may introduce significant vertical forces and resulting bending moments at the edges of the loading beds, while these forces and bending moments are absent or present only to a far less significant degree when the loading beds of two trailer modules are connected to each other. Therefore, it is quite surprising that the main loading bed connector has proven suitable for supporting jack systems.

[0033] Furthermore, the trailer system according to the invention eliminates or at least reduces the need for a load distributor to support the trailer system. Due to the presence of multiple wheels, the load is typically well distributed.

[0034] The trailer system according to the invention, for example, allows for the pickup of an object to be transported at a low location, transporting it to its destination and lifting it to a significant height, such as at least 6 meters, while supporting the object at the same location on the object via a single trailer system and with little or no additional local rigging during transport and lifting.

[0035] In an embodiment of the trailer system according to the invention, the jack has an upper jack surface. The upper jack surface is the surface of the jack that engages with an object to be jacked up or down. The object to be jacked up or down can be, for example, an object to be transported or the jack box of the jack system. The upper jack surface can be retracted to a position below or at the same level as the upper surface of the loading bed of the first trailer module.

[0036] This embodiment offers a very compact design. Because the jack surface can retract back to or even below the upper surface of the loading bed, the jack system does not add any height to the trailer system, thus allowing the trailer system to be positioned under an object located at a relatively low position (e.g., 1.5 meters above ground level).

[0037] Alternatively, the jacks of the jack system may be or form part of a jack as disclosed in NL1042448.

[0038] Optionally, the jack system is suitable for moving the object to be transported over a vertical distance of at least 6 meters.

[0039] In an embodiment of the trailer system according to the invention, the jack system further includes jack boxes. Optionally, the jack system includes a plurality of jack boxes. The jack boxes are used to lift (or lower) an object over a length longer than the stroke length of the jack. The jack is adapted to lift a first jack box over its stroke length, so that the jack moves to its extended position while engaging the first jack box. The first jack box is then supported in that position, and the jack retracts to its retracted position. A second jack box is disposed on top of the jack surface, and the first jack box continues to be supported in the higher position. The jack then lifts the second jack box, and the first jack box moves upward together with the second jack box. This process is then repeated until the first jack box reaches its desired height. To lower the first jack box again, the steps are performed in reverse order.

[0040] In this embodiment, the jack has an upper jack surface that is movable between a retracted position and an extended position. The jack retainer has an opening that allows the jack box to be inserted onto the upper jack surface when it is in the retracted position. For example, the opening is located on one side or at the bottom of the jack retainer.

[0041] Optionally, the retracted position of the jack surface is located horizontally below the upper surface of the loading bed of the first trailer module.

[0042] Alternatively, the jacks of the jack system may be or form part of a jack as disclosed in NL1042448.

[0043] Optionally, the jack system is suitable for moving the object to be transported over a vertical distance of at least 6 meters.

[0044] In an embodiment of the trailer system according to the invention, the first trailer module further includes a power unit (also referred to in the art as a power assembly) adapted to control the rotation of the wheels of the first trailer module. The power unit is arranged on the first trailer module on the side opposite to the position where the first jack bracket is connected to the first trailer module.

[0045] Optionally, in this embodiment, the trailer module includes a secondary loading bed connector for rigidly connecting the loading bed of the first trailer module to the loading bed of a second trailer module, forming a combined rigid loading bed. The secondary loading bed connector is disposed below the upper surface of the loading bed of the first trailer module. The secondary loading bed connector is disposed on the opposite side of the loading bed relative to the primary loading bed connector. Optionally, the power unit is connected to the trailer module via the secondary loading bed connector.

[0046] Optionally, the power unit is configured to control the rotation of the wheels of the first trailer module. Optionally, the power unit is configured to control the rotation of the wheels of the first trailer module about a horizontal axis of rotation and a vertical axis of rotation. Optionally, the power unit is configured to individually control the rotation of each of the plurality of wheels of the first trailer module.

Optionally, the power unit is configured to control the rotational speed of each wheel about its horizontal axis of rotation.

[0048] Optionally, the power unit includes a hydraulic system for controlling the rotation of at least one wheel, optionally for controlling the rotation of all wheels of a single trailer module, and optionally for controlling the rotation of all wheels of all trailer modules in the trailer system.

[0049] Optionally, the power unit is configured to control the jacks of the jack system.
