[0019] Optionally, the center interval between two adjacent hydraulic column seat sleeves is 15 cm.

[0020] The safety bearing device provided by the present invention has the following advantages:

[0021] 1. The present invention provides a safe bearing device, comprising a connected bottom platform, a plurality of hydraulic column seat sleeves, a plurality of hydraulic pistons and a plurality of bottom plate cover units, wherein a cavity is arranged inside the connected bottom platform, and the cavity is filled with hydraulic oil; the hydraulic column seat sleeve is installed on the upper side of the connected bottom platform, and the interior of the hydraulic column seat sleeve is connected with the hollow cavity in the connected bottom platform; the hydraulic piston is sleeved on the hydraulic column seat sleeve and the two correspond to each other, and the hydraulic piston is driven by the hydraulic oil to move upward relative to the hydraulic column seat sleeve, or the hydraulic piston is moved downward relative to the hydraulic column seat sleeve by the pressure of the object carried thereon; a bottom plate cover unit is sleeved on any of the hydraulic pistons, and a plurality of the bottom plate cover units are spliced ​​together to form a storage platform, and the storage platform is suitable for placing the load-bearing objects.

[0022] The safety load-bearing device of this structure is used to place the load-bearing object on the storage platform formed by the joint of the bottom plate cover units. The bottom plate cover unit on the lower side of the load-bearing object is pressed downward, and the hydraulic piston simultaneously moves downward relative to the hydraulic column seat sleeve and squeezes the hydraulic oil inside the hydraulic column seat sleeve to the connecting bottom platform and the inside of the rest of the hydraulic column seat sleeve, so a depression is formed on the lower side of the load-bearing object, and the load-bearing object is placed in the depression to limit its position. It is not only suitable for goods of various types and sizes, but also can effectively disperse weight, reduce maintenance costs, improve transportation efficiency and safety, and bring significant advantages to the logistics industry.

[0023] 2. The present invention provides a safety bearing device, which also includes a plurality of valve plates, which are arranged in the cavity of the connecting bottom platform, and one valve plate is arranged between any two adjacent hydraulic column seat sleeves. The valve plates around the bearing object are closed to form a supporting space on the connecting bottom platform that is suitable for the bearing object.

[0024] The safety bearing device of this structure, when the bearing object itself is small in volume and high in density, and occupies a small area of ​​the bottom plate cover unit, in order to better form a pit, the valve plates in the front, back, left and right near the placement position of the bearing object can be closed, so that a small closed space is formed inside the connected bottom platform, so that a pit can be made in a small range and the placement of goods can be stabilized. For example, when the bearing object occupies the space where four bottom plate cover units are located, the valve plates at the bottom plate cover units adjacent to the four bottom plate cover units are closed. At this time, the four bottom plate cover units and the eight bottom plate cover units on the surrounding side together constitute a whole for limiting the bearing object. The four bottom plate cover units are pressed downward to make the hydraulic oil inside flow to the eight bottom plate cover units on the surrounding side and the connected bottom platform within this range. Since the area surrounded by the twelve bottom plate cover units is smaller than the hydraulic column seat sleeve on the entire connected bottom platform, the flow of hydraulic oil has a more obvious ejection effect on the eight bottom plate cover units on the surrounding side, that is, the purpose of making a pit in a small range mentioned above is achieved.

[0025] 3. The present invention provides a safety bearing device, which also includes a valve plate switch. The acting end of the valve plate switch is connected to the valve plate, and the operating end of the valve plate switch is located on the outside of the connecting bottom platform. The valve plate is rotatably arranged in the cavity of the connecting bottom platform via a rotating shaft, and the valve plate switch is coaxially fixed with the rotating shaft.

[0026] The safety bearing device of this structure is provided with a valve plate switch, and the valve plate can be controlled by the valve plate switch, thereby controlling the depression degree of the storage platform under the bearing object.

[0027] 4. The present invention provides a safety bearing device, any of the base plate cover units is provided with a downwardly opening installation cavity, the base plate cover unit is sleeved on the circumference of the hydraulic piston through the installation cavity, the cross-section of the base plate cover unit is rectangular, and the side walls of two adjacent base plate cover units are in contact with each other.

[0028] In order to prevent the hydraulic column seat sleeve from blocking the downward movement of the base plate cover unit, the safety bearing device of this structure is arranged in such a way that the cross-sectional area of ​​the opening of the installation cavity of the base plate cover unit is larger than the cross-sectional area of ​​the hydraulic column seat sleeve. Therefore, when the base plate cover unit moves down to the hydraulic column seat sleeve, it can cover the surrounding side of the hydraulic column seat sleeve together.

In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0039] Example

[0040] This embodiment provides a safe bearing device, such as Figure 1 As shown, it includes a connecting bottom platform 1, a hydraulic column seat sleeve 2, a hydraulic piston 3, a bottom plate cover unit 4, a valve plate 5 and a valve plate switch.

[0041] like Figure 1 As shown, in this embodiment, the connecting bottom platform 1 is in the shape of a rectangular parallelepiped, and the connecting bottom platform 1 is used to be placed on the bottom plate of the cargo box of a flatbed truck. A cavity is provided inside the connecting bottom platform 1, and the cavity is filled with hydraulic oil.

[0042] like Figure 1 As shown, in this embodiment, the hydraulic column seat sleeve 2 is fixedly installed on the upper side of the connecting bottom platform 1, and the interior of the hydraulic column seat sleeve 2 is connected to the hollow cavity in the connecting bottom platform 1. The number of hydraulic column seat sleeves 2 can be selected according to specific usage requirements. The hollow cavity inside the connecting bottom platform 1 can be an oil circuit arranged inside the connecting bottom platform 1. Each hydraulic column seat sleeve 2 is connected to the oil circuit so that the hydraulic oil inside the hydraulic column seat sleeve 2 can be transported to the inside of the connecting bottom platform 1 or the hydraulic oil inside the connecting bottom platform 1 can also be replenished to the inside of the hydraulic column seat sleeve 2.

[0043] In this embodiment, the hydraulic column seat sleeves 2 are arranged at equal intervals on the upper side of the communicating bottom platform 1. As a preferred embodiment, the center interval between two adjacent hydraulic column seat sleeves 2 is 15 cm.

[0044] like Figure 1As shown, in this embodiment, the hydraulic piston 3 is sleeved on the hydraulic column seat sleeve 2 and the two correspond one to one, that is, the number of hydraulic pistons 3 is consistent with the number of hydraulic column seat sleeves 2, so as to ensure that each hydraulic column seat sleeve 2 can be sleeved with a hydraulic piston 3. Among them, the hydraulic piston 3 is driven by the hydraulic oil to move up relative to the hydraulic column seat sleeve 2, or the hydraulic piston 3 is driven by the pressure of the object carried thereon to move down relative to the hydraulic column seat sleeve 2. The hydraulic piston 3 and the hydraulic column seat sleeve 2 can both adopt existing hydraulic structural parts. Since the hydraulic column seat sleeve 2 is connected to the cavity inside the connecting bottom platform 1, when the hydraulic piston 3 is subjected to downward pressure, the hydraulic piston 3 can squeeze the hydraulic oil inside the hydraulic column seat sleeve 2 into the inside of the connecting bottom platform 1, thereby realizing the downward movement of the hydraulic piston 3; similarly, by squeezing the hydraulic oil inside the connecting bottom platform 1 to enter the inside of the hydraulic column seat sleeve 2, the descending hydraulic piston 3 can also be lifted up.

[0045] like Figure 1 As shown, in this embodiment, a bottom plate cover unit 4 is sleeved on any hydraulic piston 3, and a plurality of bottom plate cover units 4 are spliced ​​together to form a storage platform, and the storage platform is suitable for placing objects. Specifically, any bottom plate cover unit 4 is provided with a mounting cavity opening downward, and the bottom plate cover unit 4 is sleeved on the side of the hydraulic piston 3 through the mounting cavity.

[0046] In this embodiment, in order to prevent the hydraulic column seat sleeve 2 from blocking the downward movement of the base plate cover unit 4, the cross-sectional area of ​​the opening of the installation cavity of the base plate cover unit 4 is set to be larger than the cross-sectional area of ​​the hydraulic column seat sleeve 2. Therefore, when the base plate cover unit 4 moves down to the hydraulic column seat sleeve 2, it can cover the circumferential side of the hydraulic column seat sleeve 2 together.

[0047] In this embodiment, in order to facilitate splicing of multiple bottom plate cover units 4 into a complete storage platform, the cross section of the bottom plate cover unit 4 is rectangular, and the side walls of two adjacent bottom plate cover units 4 are in contact with each other.

[0048] like Figure 1 As shown, in this embodiment, the valve plate 5 is arranged in the cavity of the connecting bottom platform 1, and a valve plate 5 is arranged between any two adjacent hydraulic column seat sleeves 2. The valve plate switch (not shown in the figure) is columnar, and its active end is connected to the valve plate 5, and the valve plate switch operating end is on the outside of the connecting bottom platform 1.

[0049] As mentioned above, the cavity inside the connected bottom platform 1 can be an oil circuit arranged inside the connected bottom platform 1, and each hydraulic column seat sleeve 2 is connected to the oil circuit. A valve plate 5 is arranged between any two adjacent hydraulic column seat sleeves 2. When in use, the valve plate switch controls the opening or closing of the valve plate 5, which can control the connection and disconnection of the hydraulic oil inside the hydraulic column seat sleeve 2 and the cavity of the connected bottom platform 1 as a whole.

[0050] In this embodiment, when the load object itself is small in size and has a high density, and occupies a small area of ​​the bottom plate cover unit 4, in order to better form a pit, the front, back, left and right valve plates 5 near the placement position of the load object can be closed, so that a smaller enclosed space is formed inside the connected bottom platform 1. In this way, a pit can be created in a small area to stabilize the placement of goods. For example, when the supported object occupies the space where four bottom plate cover units 4 are located, the valve plates 5 at the bottom plate cover units 4 adjacent to the four bottom plate cover units 4 are closed. At this time, the four bottom plate cover units 4 and the eight bottom plate cover units 4 on the surrounding side together constitute a whole for limiting the supported object. The four bottom plate cover units 4 are pressed downward to make the hydraulic oil inside flow to the eight bottom plate cover units 4 on the surrounding side and the connected bottom platform 1 within this range. Since the area surrounded by the twelve bottom plate cover units 4 is smaller than the hydraulic column seat sleeve 2 on the entire connected bottom platform 1, the flow of hydraulic oil has a more obvious ejection effect on the eight bottom plate cover units 4 on the surrounding side, that is, the purpose of making the pit in a small range mentioned above is achieved. It can be understood that the above-mentioned limitation on the number of bottom plate cover units 4 is only an example, and it will change according to the specific volume of the supported object when used in practice.

[0051] Specifically, the valve plate 5 is rotatably arranged in the cavity of the communicating bottom platform 1 via a rotating shaft, and the valve plate switch is coaxially fixed with the rotating shaft, so that the rotation of the valve plate 5 can be controlled by rotating the valve plate switch, thereby realizing the control of the flow of hydraulic oil inside the hydraulic column seat sleeve 2.

[0052] The safety bearing device provided in this embodiment is installed on the floor of a flatbed truck compartment when in use, and the connecting bottom platform 1 is laid flat on the floor of the cargo box. The connecting bottom platform 1, the hydraulic column seat sleeve 2 and the hydraulic piston 3 together form a closed space, which is filled with hydraulic oil. When high-density material goods are placed on the plane of the bottom plate cover unit 4, the pressure from gravity will depress the bottom plate cover unit 4, and then depress the hydraulic piston 3, discharge the hydraulic oil to the connecting bottom platform 1, and partially enter the hydraulic column seat sleeve 2 next door. The communicating vessel principle in the above process realizes the pressure balance in each hydraulic column seat sleeve 2 in the pit. The appearance of the pit ensures that the goods do not roll easily, which is especially effective for heavy spherical and disc-shaped goods.

[0053] If the cargo itself is small in size and has a high density and occupies a small area of ​​the bottom plate, in order to better form the pit, the valve plates 5 near the front, back, left and right positions of the cargo placement can be closed to form a small closed space inside the communicating bottom platform 1, so that the pit can be made in a small range and the cargo placement can be stabilized.

[0054] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
