Description

Technical Field

[0001] The invention belongs to the technical field of transportation equipment, and in particular relates to a transportation compartment with a lifting platform. Background Art

[0002] With the increasing prosperity of the transportation industry, the types of goods are also increasing. Traditional transportation equipment is mostly single-layered, and the items are directly stacked after being stacked. When unloading, it is usually necessary to take them out in order from outside to inside and from top to bottom. This form is very inconvenient; and the outer packaging of some goods cannot withstand stacking, so they need to be placed directly on the floor, resulting in a reduction in the amount of goods transported.

[0003] At present, there are trucks with double-decker compartments. By setting a movable platform in the compartment to separate the compartment into two spaces, different goods can be packed in different spaces in the compartment. The current setting of the movable platform can be driven to rise and fall by a lifting device, so that it can adjust the height to meet different needs. The lifting of the movable platform is mostly directly supported by a cylinder, a cylinder or a screw. After long-term use, there are problems such as deformation in the drive connection part, or the lifting device is damaged or broken, which causes the movable vehicle plate to directly tip sideways.

[0004] Therefore, when the movable platform of the existing double-decker truck is loaded with heavy load, it is easy for the part where the movable platform is connected to the lifting device to deform, or when people manually climb into the compartment formed by the movable frame, there will be shaking and other problems that affect normal operation. Some manufacturers will install auxiliary supports, such as adding more oil cylinders or motors to drive screws for lifting. It should be noted that the more lifting devices of auxiliary supports and stable supports, the more complicated the linkage control problems will be, and the problem of asynchronous movements will occur; and once one of the driving devices is damaged, it may also cause the movable platform to be unable to rise and fall. In addition, the auxiliary support is installed on the floor of the compartment, which makes the movable platform unable to descend to the bottom. That is, when the movable platform descends to the lowest position, there is still a certain distance between it and the floor of the compartment, which reduces the effective space in the compartment, affects the carrying capacity, and increases transportation costs.

[0073] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0074] In order to fully understand the present invention, a detailed structure will be presented in the following description. Obviously, the implementation of the present invention is not limited to the specific details familiar to those skilled in the art. The preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other embodiments.

[0075] In the description of the present invention, the term "front" refers to the direction in which the vehicle body moves forward in a normal use state, and the opposite direction is "rear"; for the convenience of describing relative positions, the direction close to the center of the vehicle body in the left and right directions is "inside", and the opposite direction is "outside"; the terms are only for the convenience of describing the present invention and simplifying the description, and cannot be understood as limiting the present invention. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0076] like Figure 1-Figure 17 As shown, a transport box 100 with a lifting platform is a box of a transport equipment, and the transport equipment can be a container or a transport vehicle such as a truck. The transport box 100 includes: a box 10, a lifting platform 20, a lifting drive device 30 and a support structure 40. In this embodiment, the box 10 is a hexahedral structure, with a base frame assembly 110, a top plate assembly 120, front and rear end plates 130 and left and right side plates 140. The base frame assembly has a base frame 111 and a bottom plate 112 laid on the base frame 111. The lifting platform 20 is located in the box 10 and can be lifted and lowered, and the space in the box 10 can be divided into two parts, upper and lower. A plurality of lifting drive devices 30 are provided to drive the lifting platform 20 to rise and fall. The lifting drive device 30 can have various forms, and can be driven by a cylinder, a cylinder, a slide rail structure, etc.

[0077] In some other embodiments, the transport vehicle body 100 may also be of a frame type, without all or part of the side panels, end panels, or top panel assemblies.

[0078] In order to increase the stability of the lifting platform 20 after it is lifted to the required position, a plurality of support structures 40 are provided between the base frame 111 and the lifting platform 20. A plurality of lower mounting seats 113 are provided on the base frame 111, and the lower mounting seats 113 are used to mount the lower end of the fixed support structure 40. A through opening 1121 for the support structure 40 to pass through is provided on the bottom plate 112, and the through opening 112 penetrates the bottom plate 112 in the up and down direction. A plurality of upper mounting seats 250 are provided on the lifting platform 20, and the upper mounting seats 45 are used to mount the upper end of the fixed support structure 40.

[0079] In this embodiment, by setting a plurality of support structures 40, which are supported between the base frame 111 and the lifting platform 20, the support for the lifting platform 20 is increased, which is beneficial to improve the stability of the lifting platform 20 after it is raised, and ensures the reliability of use; and by installing the support structure 40 on the base frame 111, the force performance is guaranteed, and a stable supporting force can be provided. And the lower mounting seat 113 is set on the base frame 111, and a through opening 1121 is opened on the bottom plate 112, so that the lower mounting seat 113 does not occupy the space inside the car body 10; when the lifting platform 20 is in the grounded state, the lifting platform 20 can land on the bottom plate 112, which is beneficial to increase the effective volume in the car body 10.

[0080] See Fig.13 and Fig.14As shown, in order to further reduce the height of the lifting platform 20 after landing, the lifting platform 20 has two lifting side beams 210 located on the left and right sides, and a plurality of lifting cross beams 220 connected between the two lifting side beams 210, and the lifting side beams 210 protrude downward from the lifting cross beams 220. When the lifting platform 20 descends and lands, the lifting side beams 210 will first reach the plane where the bottom plate 112 is located, and at this time, the lifting cross beams 220 are located above the bottom plate 112. If the lifting side beams 210 fall on the plane where the bottom plate 112 is located and cannot continue to fall, the space between the lifting cross beams 220 and the bottom plate 112 will become an invalid space in the car body 10 and cannot be used. Therefore, accommodating notches 1111 for accommodating the lifting side beams 220 protruding downward are respectively provided on the left and right sides of the base frame 111. When the lifting platform 20 is in the grounded state, the lifting beam 220 is adjacent to the bottom plate 112, that is, the lifting beam 220 is in contact with the bottom plate 112, so that the contact area between the lifting platform 20 and the bottom frame assembly is increased; at the same time, the lower end of the lifting side beam 210 is in contact with the bottom surface of the receiving slot 1111, that is, the part of the lifting side beam 210 protruding downward from the lifting beam 220 is located in the receiving slot 1111, and the lower part of the lifting side beam 210 is located in the receiving slot 1111. It is preferred to set the lifting side beam 210 to contact the bottom surface of the receiving slot 1111. Compared with only the lifting side beam 210 contacting the bottom frame, the contact area between the lifting platform 20 and the bottom frame assembly is greatly increased, which is conducive to improving the support force performance.

[0081] The structure of the accommodating notch 1111 can be formed by welding after bending a steel plate, or by combining two parts. In this embodiment, the chassis 111 has two main side beams 1112 located on the left and right sides, and a plurality of main cross beams 1113 connected between the two main side beams 1112; the accommodating notch 1111 is arranged on the main side beam 1112, and the main side beam 1112 has a side beam main body 11121 and an auxiliary beam 11122 arranged outside the side beam main body 11121; the height of the auxiliary beam 1112 is less than the height of the side beam main body 11121, and the side beam main body 11121 and the auxiliary beam 11122 are arranged to form the accommodating notch 1111.

[0082] The lower end of the auxiliary beam 11122 is flush with the lower end of the side beam body 11121, the upper end surface of the auxiliary beam 11122 is lower than the upper end surface of the side beam body 11121, and the auxiliary beam 1112 and the side beam body 11121 are fixedly connected, such as by welding. The receiving notch 1111 is formed by surrounding the side beam body 11121 and the auxiliary beam 11122 after being fixedly connected, which is conducive to ensuring the structural strength of the main side beam 1112 after the receiving notch 1111 is provided.

[0083] In this embodiment, the side beam body 11121 is in the shape of a channel steel, and the opening direction of the channel steel is inward, so that the end of the main crossbeam 1113 can be inserted into the groove of the channel steel, which is beneficial to increase the contact area between the main crossbeam 1113 and the side beam body 11121 and improve the firmness after fixation. The auxiliary beam 11122 is in a square tube structure and is welded and fixed on the side beam body 11121. The lower mounting seat 113 is fixed on the inner side of the side beam body 11121. The width of the lifting side beam 210 is smaller than the width of the auxiliary beam 11122, which ensures that the lifting side beam 210 can easily enter or exit the accommodating slot 1111.

[0084] See also Figure 7-Figure 9 , explaining the arrangement of the lifting drive device 30. In this embodiment, four lifting drive devices 30 are arranged opposite to each other in the compartment 10. In other embodiments, other numbers of lifting drive devices 30 may be arranged. The lifting drive device 30 is arranged in the compartment 10 and needs to occupy the space inside the compartment 10. Therefore, the smaller the space occupied by the lifting drive device 30, the better.

[0085] The lifting drive device 30 comprises a shell 310 whose lower end is fixed in the receiving slot 1111, a driving structure located in the shell 310, and a pushing block 320 connected to the driving structure, wherein the pushing block 320 is located in the shell 310 so as to be movable up and down. The lower end of the shell 310 is arranged in the receiving slot 1111, so that the width of the shell 310 is narrow and the shell 310 is located at the edge of the compartment 10. The upper end of the shell 310 is fixed on the top plate assembly 120. The lifting side beam 210 is provided with a lifting side beam body 211, a lifting lifting part 212 located on the inner side of the shell 310, and a side beam connecting part 213 connected between the lifting lifting part 212 and the lifting side beam body 211, and the lifting lifting part 212 and the side beam connecting part 213 are surrounded to form an avoidance slot 214 for avoiding the shell 310 inward.

[0086] The lifting and lifting part 212 is arranged flush with the lifting beam 220, that is, when the lifting platform 20 is on the ground, the lower end of the lifting and lifting part 212 is in contact with the bottom plate 112. A lifting opening 2121 is provided on the lifting and lifting part 212, and the lifting drive device 30 is provided with a push column 321 that can be inserted into the lifting opening 2121; and a push column 321 extending inward is provided on the push block 320. After the lifting drive device 30 is started, the push block 320 moves up and down, so that the push column 321 drives the lifting platform 20 to move up and down.

[0087] The lifting drive device 30 also has a driving locking member 330 for locking the push block 320. A plurality of driving locking holes 311 matching the driving locking member 330 are provided on the shell 310. The driving locking member 330 is inserted into the driving locking hole 311 so that the driving locking member 330 limits the push block 320 in the shell 310. By cooperating with the driving locking member 330 and the driving locking holes 311 different from each other, the upper and lower limits of the push block 320 can be realized. When the height of the lifting platform 20 needs to be adjusted, the driving structure of the lifting drive device 30 is started to push the push block 320 to move in the upper and lower directions in the shell 310. After reaching a suitable position, the driving locking member 330 is inserted into a suitable driving locking hole 311, and then the driving structure is closed so that the push block 320 is blocked and locked in the shell 310 by the driving locking member 330. It plays a role in supporting the lifting platform 20. After the lifting platform 20 is adjusted into place, the driving structure of the lifting drive device 30 can be closed to reduce energy consumption.

[0088] See also Figure 3-Figure 5 , Figure 10-12 As shown, the support structure 40 and the lifting platform 20 can adjust the height, and a plurality of drive locking holes 311 matching the drive locking member 330 are provided on the housing 310; so that the lifting platform 20 can be adjusted at the multiple of the spacing between the upper and lower adjacent drive locking holes 311. The support structure 40 is supported between the chassis assembly 110 and the lifting platform 20, so it is necessary to set the height of the support structure 40 to be adjustable, and the spacing of the drive locking holes 311 in the upper and lower directions matches the adjustable height of the support structure 40, so as to ensure that the support structure 40 can support the lifting platform 20 after adjustment.

[0089] Specifically, the support structure 40 is a support column combination with adjustable height; the support structure 40 has a lower support column 410 matched with the lower mounting seat 113, an upper support column 420 matched with the upper mounting seat 250, and the upper support column 420 is located inside the lower support column 410 and can be adjusted up and down. The support structure 40 also has an adjustment locking member 430 for locking the upper support column 420 and the lower support column 410, a plurality of upper adjustment holes 421 are provided on the upper support column 420, a plurality of lower adjustment holes 411 are provided on the lower support column 410, and an adjustment plug 431 that can extend into the upper adjustment hole 421 and the lower adjustment hole 411 is provided on the adjustment locking member 430.

[0090] When adjusting the height of the lifting platform 20, the following steps are included:

[0091] S10. Start the lifting drive device 30 and adjust the lifting platform to the required height;

[0092] S20. Install and fix multiple support structures 40;

[0093] S30. The drive locking member 330 is mounted on the housing 310 to limit the movement of the lifting platform 20;

[0094] S40. Turn off the lifting drive device 30.

[0095] In step S20, the following steps are included:

[0096] S21. The lower end of the lower support column 410 is fixed to the lower mounting seat 113;

[0097] S22. The upper support column 420 is sleeved into the lower support column 410, and then the upper end of the upper support column 420 is fixed to the upper mounting seat 250;

[0098] S23 . Lock the upper support column 420 and the lower support column 410 using the adjustment locking member 430 .

[0099] In this embodiment, the adjustment locking member 430 also has an adjustment limiting plate 432 connected to the adjustment plug 431. The adjustment plug 431 has an insertion end and a terminal end. The adjustment limiting plate 432 is connected to the terminal end of the adjustment plug 431.
