Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings, which illustrate representative embodiments of the present invention and not limit the present invention.

Containers are typically welded and formed from components including a floor, end walls, side walls, and roof. The underframe mainly comprises two longitudinally arranged bottom side beams, a plurality of bottom cross beams vertically arranged between the two bottom side beams and arranged at intervals, and a floor paved on the bottom cross beams. At present, two types of common dry container floors are mainly wood floors and steel floors.

With the development of society, containers are not only used for cargo transportation, but also widely used for equipment integration. More stringent requirements are also imposed on the operating conditions and functions of such containers for equipment integration. When the container is used for equipment integration, the equipment is positioned inside the container and connected to the upper part of the underframe. When the equipment is installed, debugged or maintained, a part of engine oil, lubricating oil, grease, sewage and the like can overflow and flow on the floor, so that the floor is polluted, the environment and the appearance are affected, even other equipment is damaged, and the personnel can slip and fall.

Some devices have high requirements on the accuracy and the planeness of mounting hole sites due to large size specifications. For this situation, there are two main ways for container manufacturers to solve at present:

one way is to weld the mounting pad on the conventional steel floor underframe, and then integrally machine the mounting hole on the underframe. The processing mode needs the whole transferring processing of the underframe, and has high requirements on production equipment. Most container manufacturers do not have related production equipment, and the container manufacturers also need to carry out external cooperation production, so that logistics and external cooperation expenses are additionally increased, and the cost is high.

In another mode, the mounting holes of the mounting base plate are machined, and then the mounting base plate is welded on the underframe steel floor. The production costs of this approach are relatively low. However, since the welding workload is large, the production efficiency is affected, and the deformation is large in the welding process, the hole position accuracy and the flatness of the mounting hole on the mounting pad are difficult to ensure.

In order to at least partially solve the problems, the invention provides a chassis, a container with the chassis, a positioning assembly and a manufacturing method of the chassis.

As shown in fig. 1 to 11, the underframe 100 according to the present invention includes a floor 111, a bottom rail 112, a bottom side rail 113, a bottom side rail 116, and a support beam 120.

The bottom rail 112 is connected to the upper surface of the floor 111. The bottom beams 112 are disposed at intervals along the first direction D1. The first direction D1 is perpendicular to the longitudinal direction of the bottom rail 112 and parallel to the longitudinal direction of the floor 111.

The side sill 113 is attached to the upper surface of the floor panel 111. The side sill 113 intersects the bottom rail 112. At least two side sills 113 are provided. At least two side sills 113 are spaced apart along a second direction D2 perpendicular to the first direction D1. The upper surfaces of the two adjacent side sills 113, the two adjacent bottom beams 112 and the floor 111 enclose a first collecting trough 117. The first collection tank 117 is used to receive liquid, semi-solid or solid matter that the apparatus overflows or falls. The joints of the bottom rail 112 and the floor 111, and the joints of the side sill 113 and the floor 111, need to be sealed to prevent liquid in the first collecting tank 117 from seeping out. The liquid can be one or more of engine oil, lubricating oil, grease, sewage and the like. For example, the bottom beam 112 and the side sill 113 are connected to the floor 111 by welding, and full welding may be performed at the connection, thereby improving the sealing property of the connection.

The bottom side members 116 are connected to the ends of the floor panel 111 in the second direction D2, respectively. The bottom side members 116, the adjacent side sills 113, the adjacent two bottom cross members 112, and the upper surface of the floor panel 111 are enclosed to form a second collecting groove 118. The second collection tank 118 is at least for receiving liquid, semi-solid, or solid matter that spills or falls from the apparatus. The junction of the bottom side member 116 and the floor 111 requires a sealing process to prevent liquid in the second collecting tank 118 from seeping out. The liquid can be one or more of engine oil, lubricating oil, grease, sewage and the like. For example, the bottom side member 116 is welded to the floor 111, and full welding may be performed at the joint, thereby improving the sealing property of the joint.

The support beam 120 is detachably connected to an upper portion of the side sill 113 and/or an upper portion of the bottom rail 112. The length direction of the support beam 120 is parallel to the first direction D1. The support beam 120 has a support surface 121 for supporting the apparatus. The support surface 121 is parallel to the floor 111.

According to the underframe 100 of the present invention, the first collecting groove 117 is formed by enclosing the upper surfaces of the two adjacent side sills 113, the two adjacent bottom beams 112 and the floor 111, the supporting beam 120 is detachably connected by at least one upper portion of the bottom beams 112 and the side sills 113, and the apparatus is supported by the supporting surface 121 on the supporting beam 120. By adopting the scheme of the invention, the first collecting tank 117 can collect the liquid overflowed by the equipment, so that the liquid is isolated from the floor 111 except the first collecting tank 117, and the first collecting tanks 117 are mutually independent, so that the liquid can be prevented from flowing randomly on the floor 111, other parts of the equipment and other equipment can be prevented from being damaged, and the liquid on the floor 111 can be prevented from slipping due to the fact that people step on the liquid. Furthermore, the support beam 120 for the support apparatus can be disassembled, thereby facilitating the separate processing of the support beam 120, thereby helping to ensure the flatness of the support beam 120, and also facilitating the adjustment of the flatness of the support surface 121 of the support beam 120 when the support beam 120 is installed.

See fig. 2 and 3, and fig. 6-11. For example, the support surface 121 may be configured as a top surface of the support beam 120. This facilitates viewing while adjusting the planarity of the support surface 121 while also helping to raise the height of the bottom of the device and reducing the chance of liquid in the first collection tank 117 contacting the device.

See fig. 1-3, and fig. 6-11. Further, the top of the side sill 113 has a first mounting hole 114a. The first mounting hole 114a is provided extending in a third direction D3 perpendicular to the floor 111. The first mounting holes 114a are spaced apart along the first direction D1. The support beams 120 are parallel to the side sill 113. The support beam 120 has a second mounting hole 122. The second mounting hole 122 is disposed through along the third direction D3, that is, the second mounting hole 122 is a through hole. And, the second mounting hole 122 is configured as a counterbore. The position of the second mounting hole 122 corresponds to the position of the first mounting hole 114a. The chassis 100 may further include a first threaded fastener 130. The first threaded fastener 130 is provided through the first and second mounting holes 114a and 122 to fasten the support beam 120 to the side sill 113. The first threaded fastener 130 may be configured as a bolt and nut, and the second mounting hole 122 may be configured as a counterbore to prevent the first threaded fastener 130 from interfering with the apparatus beyond the support surface 121.

See fig. 6-11. Further, a third mounting hole 123 is formed at the top of the support beam 120. The third mounting holes 123 are disposed at intervals along the first direction D1. The third mounting hole 123 is for a fitting connection to a device. It will be appreciated that the third mounting holes 123 may be used to pass through bolts to secure the support beam 120 to the apparatus. The hole position of the third mounting hole 123 may correspond to a mounting hole on the bottom of the device, or may correspond to a hole position of a mounting hole on a mounting bracket of the device.

See fig. 1-3, and fig. 6-11. In the illustrated embodiment, the top surface of the side sill 113 is not lower than the top surface of the bottom rail 112. That is, the side sill 113 is higher than the bottom rail 112. In this way, when the parts are individually machined, the number of side sills 113 is generally smaller than that of the bottom cross members 112, and it is relatively easy to ensure machining accuracy. When the equipment is mounted, the side sill 113 can be used as a supporting structure for supporting the equipment, and interference between the mounted equipment and the bottom rail 112 can be prevented.

See fig. 1-3, and fig. 6-11. For example, the side sill 113 may be constructed as a plate member having an L-shaped cross section. The side sill 113 includes a first horizontal plate 114 and a first vertical plate 115. The first horizontal plate 114 is parallel to the floor 111. The first horizontal plate 114 is provided with a first mounting hole 114a. The upper end of the first vertical plate 115 is connected to the first horizontal plate 114. The lower end of the first vertical plate 115 is connected to the floor 111. The support beam 120 is supported and connected by the first horizontal plate 114, receives a load by the first vertical plate 115 as a support structure, and transfers the load to the bottom rail 112 by connecting the bottom rail 112, thereby contributing to the improvement of the overall strength of the chassis 100.

See fig. 1-3, and fig. 6-11. In the illustrated embodiment, two side sills 113 may be provided. The first horizontal plate 114 is located on the opposite side of the two side sills 113. By providing two side sills 113 as support structures for supporting the device, it is also possible to achieve the object of reliably supporting the device while simplifying the construction of the chassis 100 by ensuring that the projection of the center of gravity of the device onto the chassis 100 is located between the two side sills 113. The first horizontal plate 114 is disposed on the opposite side of the two side sills 113, which contributes to increasing the size of the first collecting tank 117 in the second direction D2, so that more oil can be received, and thus oil can be prevented from overflowing, compared to the first horizontal plate 114 disposed on the side of the two side sills 113 away from each other.

See fig. 1 and 3, and fig. 6-11. Alternatively, the distribution area of the side sills 113 on the floor 111 is near one end of the floor 111 in the second direction D2. Thus, a walkway for personnel to walk can be formed between the distribution area of the side sill 113 and the other end of the floor 111, and the personnel can conveniently carry out maintenance and overhaul and other operations on the equipment.

See fig. 1-3, and fig. 6-11. In any of the above embodiments, the side sill 113 is preferably provided in two. Accordingly, two support beams 120 are provided. This helps to simplify the structure of the chassis 100, thereby more advantageously ensuring the flatness of the support surface 121 and the hole position accuracy of the first, second, and third mounting holes 114a, 122, and 123.

See fig. 6-11. In addition, the chassis 100 may further include an adjustment pad 140. The adjustment shim 140 is detachably disposed between the support beam 120 and the side sill 113 to adjust the flatness of the support surface 121. For example, when the support beam 120 is installed, the height of a certain position of the support surface 121 is low with respect to other positions, and then the adjustment shim 140 may be added between the position of the support beam 120 and the side sill 113, thereby raising the height at the position.

See fig. 6-11. In order to prevent the adjustment shim 140 from slipping in a horizontal direction during use. The tuning pad 140 may be provided with a first via (not shown). The first via is for threading the first threaded fastener 130. Thus, when the support beam 120 is connected to the side sill 113, the adjustment shim 140 can be placed at the position where the first mounting hole 114a is located, and the degree of freedom of the adjustment shim 140 in the horizontal direction can be restricted by the first screw fastener 130.

See fig. 1-3, and fig. 6-11. In addition, the chassis 100 includes a bottom side rail 116. The bottom side member 116 is connected to an end of the floor 111 in the second direction D2. The bottom of the bottom side member 116 extends below the floor 111. This prevents the floor 111 from directly contacting the surface such as the bottom surface, and thus protects the floor 111.

See fig. 1-11. One configuration of the undercarriage 100 of the present invention will be described in detail below using the undercarriage 100 of an equipment integrated container with a 40-gauge gooseneck 171 as an example.

The undercarriage 100 of the present invention may include a bottom side rail 116, a bottom cross rail 112, a bottom side rail 113, a floor 111, a support beam 120, a gooseneck groove 171, a goose cross rail 172, a goose center rail 173, a center rail 174, and the like.

The bottom rail 112 and the side sill 113 are disposed to intersect and are fixedly attached to the upper surface of the floor panel 111. A first collecting groove 117 is formed between the adjacent two bottom beams 112, the adjacent two side sills 113 and the upper surface of the floor 111 in a surrounding manner so as to receive the oil overflowed from the apparatus. The support beam 120 is detachably connected to the top of the chassis main body 110. The support beam 120 has a support surface 121 for supporting the apparatus. The support surface 121 is provided with a second mounting hole 122 and a third mounting hole 123. The second mounting hole 122 is provided corresponding to the first mounting hole 114a. The third mounting hole 123 is for a fitting connection to a device, for example, the third mounting hole 123 is fastened to the device by a bolt and a nut. The positioning assembly may include a positioning frame 150 and a second threaded fastener 160. The positioning frame 150 has a positioning hole 151a and a second via hole 151b.

In step S1, when the underframe 100 has the parts such as the gooseneck groove 171, the goose cross member 172, the goose center sill 173, and the center sill 174, the parts such as the gooseneck groove 171, the goose cross member 172, the goose center sill 173, and the center sill 174 may be processed by referring to the steps;

Step S2: the positions of the bottom side member 116, the bottom cross member 112, and the bottom side member 113 are determined. In this step, the positions of the bottom cross member 112 and the side sill 113 may be determined by scribing or spot welding the positioning blocks on the tooling table. In the case where the under frame 100 has the gooseneck groove 171, the goose cross member 172, the goose center sill 173, and the center sill 174, the positions of the gooseneck groove 171, the goose cross member 172, the goose center sill 173, and the center sill 174 may also be determined with reference to this step.

Step S7: after checking the welding structure of the chassis 100 and the positioning of the floor 111, welding is performed to form the chassis main body 110. A first collecting groove 117 is formed between each two adjacent bottom beams 112, each two adjacent side sills 113, and the floor 111 on the chassis main body 110. The bottom side member 116, the adjacent one of the bottom side members 113, the adjacent two of the bottom cross members 112, and the upper surface of the floor panel 111 are enclosed to form a second collecting groove 118.

Step S10: after the flatness adjustment is completed, the first threaded fastener 130 is inserted through the second through hole 151b and is inserted into the second mounting hole 122 and the first mounting hole 114a to fix the support beam 120 to the bottom cross member 112 or the bottom side member 113;

step S11: the second threaded fastener 160 is removed and the positioning frame 150 is removed, completing the fabrication of the chassis 100.
