In the following, 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 do not limit the present invention.

Containers are typically constructed by welding together components including a base frame, end walls, side walls and a 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, the floor of the common container dry cargo box is mainly divided into two types, namely a wood floor and a steel floor.

With the development of society, the container is not only applied to freight transportation, but also can be widely applied to equipment integration. More stringent requirements are also placed on the operating conditions and the operating functions of such containers for the integration of devices. When the container is used for equipment integration, the equipment is located inside the container and is connected to the upper part of the chassis. Many equipment integration containers, when equipment fixing debugs or maintain, all can spill over partial machine oil, lubricating oil, grease, sewage etc. and trickle on the floor, not only pollute the floor, influence the environment and pleasing to the eye, cause other equipment damages even, still can cause personnel's slip tumble injury.

Some equipment has high requirements on the precision and the planeness of mounting hole sites due to large size and specification. For this situation, at present, there are two main ways for container manufacturers to solve the problem:

one method is to weld the mounting base plate on the traditional steel floor underframe and then integrally machine the mounting holes on the underframe. The processing mode needs the whole transfer processing of the underframe, and has high requirements on production equipment. Most container manufacturers do not have related production equipment, and need to carry out outside cooperation production, so that logistics and outside cooperation expenses are additionally increased, and the cost is high.

The other mode is that the mounting holes of the mounting base plate are processed, and then the mounting base plate is welded on the underframe steel floor. The production costs of this approach are relatively low. However, the welding workload is large, which affects the production efficiency, and the welding process is easy to generate a large deformation, so that the hole site precision and the flatness of the mounting hole on the mounting base plate are difficult to ensure.

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

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

The base cross member 112 is connected to the upper surface of the floor panel 111. The bottom cross members 112 are spaced apart along the first direction D1. The first direction D1 is perpendicular to the length direction of the base cross member 112 and parallel to the length direction of the floor panel 111.

The bottom longitudinal beams 113 are connected to the upper surface of the floor panel 111. The bottom longitudinal beams 113 intersect the bottom cross beam 112. At least two bottom longitudinal beams 113 are provided. At least two bottom longitudinal beams 113 are disposed at intervals in a second direction D2 perpendicular to the first direction D1. The upper surfaces of two adjacent bottom longitudinal beams 113, two adjacent bottom cross beams 112 and the floor 111 enclose a first collection trough 117. The first holding tank 117 is used to receive liquid, semi-solid or solid matter that overflows or falls down the apparatus. The joints of the bottom cross beams 112 and the floor 111, and the joints of the bottom longitudinal beams 113 and the floor 111 need to be sealed to prevent the 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 cross beams 112 and the bottom longitudinal beams 113 are both connected to the floor 111 by welding, and full welding can be performed at the joints, so that the sealing performance of the joints is improved.

The bottom side members 116 are connected to ends of the floor panel 111 in the second direction D2, respectively. A second collecting groove 118 is formed by enclosing the bottom side beam 116, the adjacent bottom longitudinal beams 113, the two adjacent bottom cross beams 112 and the upper surface of the floor 111. The second holding tank 118 is at least used to receive liquid, semi-solid or solid matter that overflows or falls from the apparatus. The junction of the bottom side rail 116 and the floor 111 needs to be sealed to prevent liquid in the second catch 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 beams 116 are welded to the floor 111, and a full weld may be applied to the joint to improve the seal at the joint.

The support beam 120 is detachably connected to an upper portion of the bottom longitudinal beam 113 and/or an upper portion of the bottom cross beam 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 equipment. The support surface 121 is parallel to the floor 111.

According to the underframe 100 of the invention, a first collecting trough 117 is formed by the enclosure of two adjacent bottom longitudinal beams 113, two adjacent bottom transverse beams 112 and the upper surface of the floor 111, a support beam 120 is detachably connected by the upper part of at least one of the bottom transverse beams 112 and the bottom longitudinal beams 113, and the equipment is supported by means of a support surface 121 on the support beam 120. By adopting the scheme of the invention, the first collecting grooves 117 can collect the liquid overflowing from the equipment, so that the liquid is isolated from the floor 111 except the first collecting grooves 117, and the first collecting grooves 117 are independent from each other, so that the liquid can be prevented from flowing freely on the floor 111, other parts of the equipment and other equipment can be prevented from being damaged, and the equipment is more beneficial to preventing people from slipping down due to the fact that the people step on the liquid on the floor 111. Further, the support beam 120 for supporting the equipment can be disassembled, thereby facilitating separate processing of the support beam 120, helping to ensure the flatness of the support beam 120, and facilitating 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 to support a top surface of the beam 120. This facilitates viewing when adjusting the flatness of the support surface 121, and also helps to raise the height of the bottom of the apparatus, reducing the chance that liquid in the first collection trough 117 will contact the apparatus.

Refer to fig. 1 to 3, and fig. 6 to 11. Further, the top of the bottom side member 113 has a first mounting hole 114a. The first mounting hole 114a is provided to extend in a third direction D3 perpendicular to the floor panel 111. The first mounting holes 114a are spaced apart in the first direction D1. The support beams 120 are parallel to the bottom stringers 113. The support beam 120 has a second mounting hole 122. The second mounting holes 122 are disposed along the third direction D3, that is, the second mounting holes 122 are through holes. Also, 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 also include a first threaded fastener 130. First threaded fasteners 130 are inserted through the first and second mounting

holes

114a and 122 to fasten the support beam 120 to the bottom side member 113. The first threaded fastener 130 may be configured as a bolt and nut and the second mounting hole 122 as a counterbore to prevent the first threaded fastener 130 from protruding beyond the support surface 121 and interfering with the device.

See fig. 6-11. Further, a third mounting hole 123 is opened at the top of the support beam 120. The third mounting holes 123 are spaced apart in the first direction D1. The third mounting hole 123 is adapted to be connected to a device. It is understood that the third mounting hole 123 may be used to pass a bolt to fasten the support beam 120 with the equipment. The hole position of the third mounting hole 123 may correspond to the mounting hole position at the bottom of the device, or may correspond to the hole position of the mounting hole on the mounting bracket configured to the device.

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

Refer to fig. 1 to 3, and fig. 6 to 11. For example, the bottom longitudinal beam 113 may be configured as a plate member having an L-shaped cross section. The bottom longitudinal beam 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 panel 111. The support beams 120 are supported and connected by the first horizontal plate 114, bear load by the first vertical plate 115 as a support structure, and transmit the load to the bottom cross member 112 by connecting the bottom cross member 112, thereby contributing to the improvement of the overall strength of the base frame 100.

Refer to fig. 1 to 3, and fig. 6 to 11. In the illustrated embodiment, two bottom stringers 113 may be provided. The first horizontal plate 114 is located on the opposite side of the two bottom longitudinal beams 113. By providing two bottom longitudinal beams 113 as a support structure for supporting the device, it is ensured that the projection of the center of gravity of the device on the undercarriage 100 is located between the two bottom longitudinal beams 113, which also achieves a reliable support of the device and simplifies the construction of the undercarriage 100. The first horizontal plate 114 is disposed on the opposite side of the two bottom longitudinal beams 113, which is beneficial to increase the size of the first collecting groove 117 along the second direction D2 compared to the first horizontal plate 114 disposed on the side of the two bottom longitudinal beams 113 away from each other, so as to be able to receive more oil, thereby preventing the oil from overflowing.

See fig. 1 and 3, and fig. 6-11. Optionally, the distribution area of the bottom longitudinal beam 113 on the floor panel 111 is close to one end of the floor panel 111 in the second direction D2. Therefore, a walkway for people to walk can be formed between the distribution area of the bottom longitudinal beam 113 and the other end of the floor 111, and the maintenance and the overhaul of the equipment are facilitated for the people.

Refer to fig. 1 to 3, and fig. 6 to 11. In any of the above embodiments, two bottom longitudinal beams 113 are preferably provided. Accordingly, two support beams 120 are provided. This helps simplify the structure of the bottom chassis 100, and thus is more advantageous in ensuring the flatness of the support surface 121 and the hole site 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 a spacer 140. The adjustment shim 140 is detachably disposed between the support beam 120 and the bottom longitudinal beam 113 to adjust the flatness of the support surface 121. For example, when the support beam 120 is installed, if the height of the support surface 121 is low relative to other positions, the adjustment pad 140 can be added between the position of the support beam 120 and the bottom longitudinal beam 113, so as to raise the height of the position.

See fig. 6-11. To prevent the spacer 140 from slipping in a horizontal direction during use. The trim pad 140 may be opened with a first via (not shown). The first via is used to pass through the first threaded fastener 130. Thus, when the support beam 120 is connected to the bottom longitudinal beam 113, the adjustment shim 140 can be placed at the position of the first mounting hole 114a, and the degree of freedom of the adjustment shim 140 in the horizontal direction is limited by the first threaded fastener 130.

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

See fig. 1-11. The following describes in detail a structure of the underframe 100 of the equipment integrated container with a 40-foot gooseneck tunnel 171 as an example.

Referring to fig. 5 to 11 in conjunction with fig. 1 to 4. The present invention also provides a positioning assembly for use in the production of the undercarriage 100. The chassis 100 is adapted to be connected to a device. The underframe 100 includes an underframe body 110 and a support beam 120. The top of the chassis main body 110 is provided with a first mounting hole 114a. The first mounting holes 114a are spaced apart in the first direction D1. The first direction D1 is parallel to the lengthwise direction of the chassis body 110. The underframe body 110 may include the floor 111, bottom cross member 112, and bottom longitudinal member 113 described above. The bottom cross member 112 and the bottom longitudinal member 113 are arranged to intersect and fixedly connected to the upper surface of the floor panel 111. A first collecting groove 117 is formed by enclosing two adjacent bottom cross beams 112, two adjacent bottom longitudinal beams 113 and the upper surface of the floor 111, so as to receive oil overflowed by the equipment. The support beam 120 is detachably connected to the top of the base frame body 110. The support beam 120 has a support surface 121 for supporting the device. The support surface 121 is opened 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 adapted to be connected to the 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. The positioning hole 151a is provided corresponding to the third mounting hole 123. The second via hole 151b is disposed corresponding to the first mounting hole 114a, and the aperture of the second via hole 151b is larger than that of the second mounting hole 122. The second threaded fasteners 160 are respectively fitted into the positioning holes 151a and the third mounting holes 123. The second screw fastener 160 is configured to be inserted into the positioning hole 151a and the third mounting hole 123, so as to fasten the support beam 120 to the positioning frame 150. For example, the second threaded fastener 160 may include a bolt and a nut, or may include only a bolt.

According to the positioning assembly of the present invention, on the basis that the support beam 120 can be detached from the base frame body 110 and separately processed, before the support beam 120 is mounted to the base frame body 110, the positioning frame 150 of the present invention may be used to position the support beam 120 so that the positional accuracy of the support beam 120 matches the positional accuracy when connected to the equipment, and the positioning frame 150 and each support beam 120 are fastened together by the second threaded fastener 160, and then the positioning frame 150 may be detached by assembling the assembly of the positioning frame 150 and the support beam 120 to the base frame body 110 after the support beam 120 and the base frame body 110 are mounted. By employing the positioning assembly of the present invention, it is possible to position each support beam 120 to be mounted to the chassis main body 110 in advance, thereby ensuring the positional accuracy of each support beam 120 mounted to the chassis main body 110.

The connecting beams 152 are parallel to each other, and both ends of the connecting beams 152 are connected to the two positioning beams 151, respectively.

See fig. 5-11. The connecting beam 152 may be perpendicular to the positioning beam 151. The positioning beams 151 and the connection beams 152 may be made of steel plates. This ensures flatness of the positioning frame 150 itself, which contributes to improvement of positioning accuracy of the support beam 120.

See fig. 1-11. The present invention also provides a method for manufacturing the bottom chassis 100, wherein the method for manufacturing the bottom chassis 100 comprises the following steps:

Wherein the position of the second mounting hole 122 corresponds to the position of the first mounting hole 114a. The position of the positioning hole 151a corresponds to the position of the third mounting hole 123. The position of the second via hole 151b corresponds to the position of the second mounting hole 122, and the aperture of the second via hole 151b is smaller than the aperture of the second mounting hole 122. The second mounting hole 122 is a counterbore. In step S1, when the underframe 100 has parts such as the gooseneck groove 171, the gooseneck beam 172, the gooseneck beam 173, and the middle beam 174, the parts such as the gooseneck groove 171, the gooseneck beam 172, the gooseneck beam 173, and the middle beam 174 may be processed with reference to this step;

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, positions of the bottom cross member 112 and the bottom side member 113 may be determined on the tooling table by scribing, spot welding, or the like. In the case where the bottom frame 100 has the gooseneck groove 171, the gooseneck beam 172, the gooseneck beam 173, and the center cross beam 174, the positions of the gooseneck groove 171, the gooseneck beam 172, the gooseneck beam 173, and the center cross beam 174 may be determined by referring to this step.

And step S4: and after the positioning of the bottom side beams 116, the bottom cross beams 112 and the bottom longitudinal beams 113 is checked to be correct, welding is carried out to form a welding structure of the underframe 100. Similarly, the gooseneck groove 171, the gooseneck beam 172, the gooseneck beam 173, and the middle beam 174 may be welded together to form a corresponding welded structure of the underframe 100.

Step S5: the bottom surface of the welding structure of the base frame 100 is turned upward, and the position of the floor panel 111 is determined on the bottom surface of the welding structure of the base frame 100 turned upward.

Step S6: according to the determined position of the floor 111, the floor 111 is placed on the bottom surface of the welding structure of the base frame 100, and the floor 111 and the welding structure of the base frame 100 are spot-welded.

Step S7: after checking the positioning of the welding structure of the underframe 100 and the floor 111, welding is performed to form the underframe body 110. On the underframe main body 110, a first collecting groove 117 is formed by enclosing between each two adjacent bottom cross beams 112, each two adjacent bottom longitudinal beams 113 and the floor 111. A second collecting groove 118 is formed by enclosing the bottom side beam 116, the adjacent bottom longitudinal beam 113, the two adjacent bottom cross beams 112 and the upper surface of the floor 111.

Step S8: the positioning frame 150 and the support beam 120 are connected together to form an assembly by using the second threaded fastener 160 to pass through the positioning hole 151a and the third mounting hole 123. Before step S8 and after step S7, the weld can be ground and trimmed, and the weld quality can be checked to check the part position size.

Step S9: the combined body is placed on the corresponding bottom cross beam 112 or bottom longitudinal beam 113, and an adjusting shim 140 is placed between the positioning frame 150 and the corresponding bottom cross beam 112 or bottom longitudinal beam 113 according to the flatness of the corresponding bottom cross beam 112 or bottom longitudinal beam 113 so as to compensate for the flatness error of the supporting surface 121 of the supporting beam 120.

Step S10: after the flatness adjustment is completed, the first threaded fastener 130 is used to penetrate through the second through hole 151b and the second mounting hole 122 and the first mounting hole 114a, so as to fix the support beam 120 on the bottom cross beam 112 or the bottom longitudinal beam 113;

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

By adopting the manufacturing method, not only the production cost and the labor intensity are reduced, but also the hole position precision of the third mounting hole 123 on the support beam 120 and the flatness of the support surface 121 are improved.

For example, in the case where the chassis main body 110 and/or the support beam 120 need to be painted, the above-mentioned steps S8 to S11 may be performed after the painting process is completed.

The equipment is mounted above the bottom cross beams 112 and bottom longitudinal beams 113. The bottom cross member 112, the bottom longitudinal member 113, and the floor 111 divide the underframe 100 into a plurality of independent isolation zones (first collection grooves 117). The device has the advantages that the generated engine oil, lubricating oil, grease, sewage and the like can be collected in a fixed area and do not flow everywhere on the floor 111 any more when the device is installed, debugged, maintained and maintained.
