Description

Technical Field

[0001] The present application relates to the technical field of logistics and transportation, and in particular to a flexible cargo platform and a transport vehicle. Background Art

[0002] The transport truck is a very important logistics and transportation equipment, which saves a lot of labor and provides convenience for people. With the development of society, the types of goods that need to be transported are gradually increasing, and many goods with strange shapes have appeared. In order to facilitate the transportation of various types of goods, it is necessary to install a loading platform on the placement platform of the transport truck.

[0003] The cargo platform installed on the existing transport truck includes a telescopic rod and a spring. There are several telescopic rods and they are vertically arranged in the same horizontal plane. The fixed rod body of the telescopic rod is fixedly connected to the placement platform. There are several springs and they correspond to the telescopic rods one by one. The springs are vertically arranged in the corresponding telescopic rods. When placing the goods, the workers place the goods on the telescopic rod. The goods rely on their own gravity to squeeze the telescopic rod and the spring, so that the movable rod body of the telescopic rod is concave to form a placement space, which is convenient for placing goods of different shapes.

[0004] During the placement process of the above-mentioned goods, the placement space is formed only by the weight of the goods themselves. When transporting goods with lighter weight, the placement space formed by the goods relying on their own gravity is smaller, which may cause the telescopic rod to lose its restraining effect on the goods, making it inconvenient to store the goods stably. Summary of the invention

[0005] In order to solve the above technical problems, the present application provides a flexible cargo platform and a transport vehicle.

[0006] The present application provides a flexible cargo platform, which adopts the following technical solution:

[0007] In a first aspect, the present application provides a flexible cargo platform, which adopts the following technical solution:

[0008] A flexible cargo platform, comprising:

[0009] The support assembly comprises a support plate, a support telescopic rod, a support tube and a first one-way valve. The support plate is horizontally arranged above the placement platform of the transport vehicle and is fixedly connected to the transport vehicle body, and a distance is left between the support plate and the placement platform of the transport vehicle; a plurality of support telescopic rods are arranged and are all vertically arranged in the same horizontal plane. The fixed rod body of the support telescopic rod is located between the support plate and the placement platform of the transport vehicle, and is fixedly connected to the support plate and the placement platform of the transport vehicle; the movable rod body of the support telescopic rod is slidably inserted on the support plate in the vertical direction; a plurality of support tubes are arranged and correspond to the support telescopic rods one by one. One end of the support tube is connected to the rodless cavity of the support telescopic rod and the other end is connected to the rod cavity of the support telescopic rod. Liquid fluid is preset in the support tube, the rodless cavity of the support telescopic rod and the rod cavity of the support telescopic rod; a plurality of first one-way valves are arranged and correspond to the support tubes one by one. The first one-way valve is installed in the corresponding support tube and is used to make the fluid in the rodless cavity of the support telescopic rod flow into the rod cavity of the support telescopic rod;

[0010] A plurality of rebound components are provided, and correspond to the supporting telescopic rods one by one. The rebound components include a rebound tube and a first spring. One end of the rebound tube is connected to the rodless cavity of the supporting telescopic rod, and the other end is connected to the rod cavity of the supporting telescopic rod. Liquid fluid is preset in the rebound tube. The first spring is vertically arranged in the rodless cavity of the supporting telescopic rod.

[0011] A plurality of limiting components are provided, and correspond to the rebound tubes one by one. The limiting components are provided on the corresponding rebound tubes and are used to adjust the communication area between the two ends of the rebound tubes;

[0012] There are several sensing components, which correspond to the supporting telescopic rods one by one. The sensing components are arranged on the corresponding supporting telescopic rods, and the working state of the limiting component is adjusted based on the pressure between the placed goods and the supporting telescopic rods.

[0013] By adopting the above technical solution, when the gravity of the transported goods is relatively large, the goods can rely on their own gravity to produce an extrusion effect on the supporting telescopic rod, so that the sensing component drives the limiting component to isolate the two ends of the rebound tube from each other. At this time, the goods can rely on their own large gravity to complete the downward extrusion of the first spring, so that the supporting telescopic rod can be stably compressed to below the preset length, providing a larger space for the stable placement of the goods, thereby enabling the goods to be stably placed during transportation;

[0014] When the gravity of the transported goods is relatively small, the goods can exert a compressive effect on the supporting telescopic rod by their own relatively small gravity, so that the sensing component drives the limiting component to isolate the two ends of the rebound tube from each other. At this time, the goods can exert a downward external force to compress the first spring, so that the supporting telescopic rod can be compressed to below the preset length;

[0015] Due to the setting of the first one-way valve and the isolation of the two ends of the rebound tube, when the external force applied to the goods is removed, the length of the supporting telescopic rod will not extend, so that the supporting telescopic rod can still be stably compressed to below the preset length, thereby allowing the goods to be stably placed during transportation;

[0016] In the prior art, when the same external force is applied to the cargo, the cargo will move upward under the elastic force when the external force is removed, causing the cargo to be unable to be placed securely;

[0017] In the above scheme, the placement space for the supporting telescopic rod to be squeezed and contracted by the goods can be achieved by the weight of the goods, and can also be stabilized by manual adjustment, which increases the weight range of cargo transportation and also improves the stability of the cargo during transportation.

[0018] Optionally, the restriction component includes:

[0019] The telescopic rod is limited, and the fixed rod body of the telescopic rod is fixedly connected to the outer wall of the rebound tube. The movable rod body of the telescopic rod is inserted on the side wall of the rebound tube. When the telescopic rod is extended, the communication area at both ends of the rebound tube gradually decreases. When the telescopic rod is extended to a preset length, the two ends of the rebound tube are isolated.

[0020] The second spring is arranged in the rod cavity of the limiting telescopic rod along the length direction of the limiting telescopic rod, and the second spring is always in a compressed state; the elastic coefficient of the second spring is smaller than the elastic coefficient of the first spring.

[0021] Optionally, the sensing component includes:

[0022] There are several induction boxes, which correspond to the supporting telescopic rods one by one. The induction boxes are made of flexible materials and have a cavity structure inside. The induction boxes are fixedly arranged above the movable rod body of the corresponding supporting telescopic rod and are fixedly connected to the movable rod body of the supporting telescopic rod;

[0023] One end of the induction tube is connected to the inside of the induction box, and the other end is connected to the rodless cavity of the telescopic rod. Liquid fluid is preset in the induction tube, the induction box, and the rodless cavity of the telescopic rod.

[0024] By adopting the above technical solution, the goods first squeeze the induction box, so that the fluid in the induction box enters the rodless cavity of the limiting telescopic rod through the induction tube, so that the limiting telescopic rod extends, and then the connecting area at both ends of the rebound tube is gradually reduced until the two ends of the rebound tube are isolated from each other, so that the elastic force of the first spring cannot drive the supporting telescopic rod to extend; thereby, the contraction length of the supporting telescopic rod is stable, which facilitates the stable placement of the goods in the placement space formed by the contraction of several supporting telescopic rods;

[0025] The induction box made of flexible material and the fluid in the induction box can both play a buffering and protective role on the goods, which is beneficial to the safe placement and safe transportation of the goods.

[0026] Optionally, the cross-sectional area of ​​the sensing box is smaller than the cross-sectional area of ​​the movable rod body supporting the telescopic rod.

[0027] Optionally, the end of the movable rod body supporting the telescopic rod is threadedly connected with a pressure compensating member, the sensing box is located inside the pressure compensating member, and the pressure compensating member is used to adjust the squeezing force exerted on the sensing box.

[0028] By adopting the above technical solution, when placing extremely light goods or goods with peculiar shapes, the edges of some goods can only squeeze a part of the sensing box, or some goods cannot completely squeeze the sensing box by their own gravity. When the above situation occurs, workers can thread the pressure compensation part onto the movable rod body of the required supporting telescopic rod, so that the squeezing received by the sensing box can be manually adjusted to meet the needs of various actual working conditions.

[0029] Optionally, the upper half of the induction tube is embedded in a movable rod body supporting the telescopic rod, and the lower half of the induction tube is located in a rodless cavity supporting the telescopic rod.

[0030] Optionally, the limiting assembly further comprises a second one-way valve installed in the rebound tube, the second one-way valve is located below the limiting telescopic rod and is used to allow the fluid in the rod cavity supporting the telescopic rod to flow into the rodless cavity supporting the telescopic rod.

[0031] In a second aspect, the present application provides a transport vehicle, which adopts the following technical solution:

[0032] A transport vehicle comprises the flexible cargo platform.

[0033] In summary, the present application includes at least one of the following beneficial technical effects:

[0034] 1. By setting a support component, a rebound component, a limiting component and a sensing component, when the gravity of the transported goods is relatively small, the goods can rely on their own relatively small gravity to produce an extrusion effect on the supporting telescopic rod, so that the sensing component drives the limiting component to isolate the two ends of the rebound tube from each other. At this time, the goods can rely on the downward external force to squeeze the first spring, so that the supporting telescopic rod can be compressed to below the preset length, providing a larger space for the stable placement of the goods, thereby enabling the goods to be stably placed during transportation; in this solution, the placement space of the supporting telescopic rod squeezed and contracted by the goods can be achieved by the dead weight of the goods, and can also be adjusted manually, thereby increasing the weight range of the goods to be transported, and also improving the stability of the goods during transportation;

[0035] 2. By setting up the pressure compensating parts, in the actual placement process of goods, due to the weight and shape of the goods themselves, there are various situations, resulting in different degrees of squeezing of each induction box by the placed goods, resulting in the fluid in some squeezed induction boxes being unable to drive the two ends of the rebound tube to be isolated, making it inconvenient to support the adjustment of the length of the telescopic rod; the application of the pressure compensating parts can meet the above-mentioned actual working conditions, so that the actual squeezing degree of the induction box can be adjusted manually, which is convenient for the placement of goods.

[0047] The following is combined with Figure 1-4 This application is described in further detail.

[0048] The embodiment of the present application discloses a flexible cargo platform for installation on a placement platform 1 of a transport vehicle.

[0049] Reference Figures 1 to 4A flexible cargo platform includes a support component 2, a rebound component 3, a limit component 4 and a sensing component 5, wherein the support component 2 is used to support the cargo and provide a placement space for the cargo, the rebound component 3 is used to provide the support component 2 with power to restore the initial state, the limit component 4 is used to limit the power release of the rebound component 3, and the sensing component 5 is used to sense the storage state of the cargo on the support component 2 and adjust the limit component based on the storage state of the cargo.

[0050] When the goods are placed on the support component 2, the sensing component 5 adjusts the working state of the limiting component 4 so that the limiting component 4 limits the power of the rebound component 3, making it impossible for the support component 2 to return to its initial state, thereby facilitating the placement of the goods on the support component 2.

[0051] Reference Figures 1 to 4 The support assembly 2 includes a support plate 21, a support telescopic rod 22, a support tube 23 and a first one-way valve 24, wherein the support plate 21 is horizontally arranged above the placement platform 1 of the transport vehicle and is fixedly connected to the transport vehicle body, and a distance is left between the support plate 21 and the placement platform 1 of the transport vehicle; a plurality of support telescopic rods 22 are arranged, and all are vertically arranged in the same horizontal plane, and the fixed rod body of the support telescopic rod 22 is located between the support plate 21 and the placement platform 1 of the transport vehicle, and is fixedly connected to the support plate 21 and the placement platform 1 of the transport vehicle.

[0053] Reference Figures 1 to 4 There are several rebound components 3, and they correspond one to one with the supporting telescopic rods 22. The rebound components 3 include a rebound tube 31 and a first spring 32, wherein one end of the rebound tube 31 is connected to the rodless cavity supporting the telescopic rod 22, and the other end is connected to the rod cavity supporting the telescopic rod 22, and liquid fluid is preset in the rebound tube 31; the first spring 32 is vertically arranged in the rodless cavity supporting the telescopic rod 22.

[0054] Reference Figures 1 to 4There are several limiting components 4, which correspond one to one with the rebound tubes 31. The limiting components 4 are arranged on the corresponding rebound tubes 31 and are used to adjust the connection area at both ends of the rebound tubes 31. There are several sensing components 5, which correspond one to one with the supporting telescopic rods 22. The sensing components 5 are arranged on the corresponding supporting telescopic rods 22 and adjust the working state of the limiting components 4 based on the pressure between the placed goods and the supporting telescopic rods 22.

[0055] Reference Figures 1 to 4 The limiting component 4 includes a limiting telescopic rod 41 and a second spring 42, wherein the fixed rod body of the limiting telescopic rod 41 is fixedly connected to the outer wall of the rebound tube 31, and the movable rod body of the limiting telescopic rod 41 is inserted on the side wall of the rebound tube 31. During the extension of the limiting telescopic rod 41, the communication area at both ends of the rebound tube 31 gradually decreases. When the limiting telescopic rod 41 is extended to a preset length, the two ends of the rebound tube 31 are isolated from each other; the second spring 42 is arranged in the rod cavity of the limiting telescopic rod 41 along the length direction of the limiting telescopic rod 41, and the second spring 42 is always in a compressed state; the elastic coefficient of the second spring 42 is smaller than the elastic coefficient of the first spring 32.

[0056] The sensing assembly 5 includes a sensing box 51 and a sensing tube 52, wherein a plurality of sensing boxes 51 are provided and correspond one to one with the supporting telescopic rods 22. The sensing box 51 is made of a flexible material and has a hollow structure inside. The sensing box 51 is fixedly arranged above the movable rod body of the corresponding supporting telescopic rod 22 and is fixedly connected to the movable rod body of the supporting telescopic rod 22; one end of the sensing tube 52 is connected to the inside of the sensing box 51, and the other end is connected to the rodless cavity of the limiting telescopic rod 41. Liquid fluid is preset in the sensing tube 52, the sensing box 51, and the rodless cavity of the limiting telescopic rod 41.

[0057] The cross-sectional area of ​​the induction box 51 is smaller than the cross-sectional area of ​​the movable rod body supporting the telescopic rod 22; the induction tube 52 is a soft tube.

[0058] The end of the movable rod body supporting the telescopic rod 22 is threadedly connected with a pressure compensation piece 6, and the induction box 51 is located inside the pressure compensation piece 6. The pressure compensation piece 6 is used to adjust the extrusion force exerted on the induction box 51. The upper half of the induction tube 52 is embedded in the movable rod body supporting the telescopic rod 22, and the lower half of the induction tube 52 is located in the rodless cavity supporting the telescopic rod 22.

[0059] During the actual placement of goods, there are many situations due to the weight and shape of the goods themselves. When placing extremely light goods or goods with strange shapes, the edges of some goods can only squeeze a part of a single induction box 51, or some goods cannot completely squeeze the induction box 51 by their own gravity, resulting in different squeezing degrees of each induction box 51 for the placed goods, and further resulting in the inability of the fluid in the partially squeezed induction box 51 to drive the two ends of the rebound tube 31 to be isolated, which is not convenient for adjusting the length of the telescopic rod 22. When the above situation occurs, the worker can thread the pressure compensation part 6 on the movable rod body of the telescopic rod 22 that needs to be supported, so that the squeezing received by the induction box 51 can be manually adjusted. The application of the pressure compensation part 6 can meet the above actual working conditions and facilitate the placement of goods.

[0060] The limiting assembly 4 further includes a second one-way valve 43 installed in the rebound tube 31 . The second one-way valve 43 is located below the limiting telescopic rod 41 and is used to allow the fluid in the rod cavity supporting the telescopic rod 22 to flow into the rodless cavity supporting the telescopic rod 22 .

[0061] The implementation principle of a flexible cargo platform in the embodiment of the present application is as follows: when placing cargo, the cargo first squeezes the induction box 51, so that the fluid in the induction box 51 enters the rodless cavity of the limiting telescopic rod 41 through the induction tube 52, thereby extending the limiting telescopic rod 41;

[0062] During the extension of the telescopic rod 41, the connection area between the two ends of the rebound tube 31 is gradually reduced until the two ends of the rebound tube 31 are completely isolated. In the present application, the cargo can rely on its own gravity to isolate the two ends of the rebound tube 31 from each other, or rely on the pressure compensation member 6 to isolate the two ends of the rebound tube 31 from each other.

[0063] When both ends of the rebound tube 31 are isolated, the telescopic rod 41 is restricted from extending to the maximum length. At this time, the cargo indirectly squeezes the movable rod body of the supporting telescopic rod 22 through the induction box 51, so that the supporting telescopic rod 22 begins to shrink.

[0064] In the present application, the cargo can drive the supporting telescopic rod 22 to retract by its own gravity, or by external force acting on the cargo, so that the size of the placement space formed by the supporting telescopic rod 22 can be adjusted according to actual working conditions.

[0065] The embodiment of the present application also provides a transport vehicle.

[0066] Reference Figures 1 to 4 , a transport vehicle includes the flexible cargo platform.

[0067] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
