The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] The variable structure fast lifting device is described below in conjunction with specific embodiments to further understand the inventive concept of the variable structure fast lifting device.

[0026] like Figure 1As shown, a first embodiment of the present invention is a variable structure quick lifting device for transporting 3DP components 3, comprising: a cushion block 1, and an adjustable platform 2 matched with the bottom of the cushion block 1; wherein the upper end surface of the cushion block 1 is designed to conform to the shape of the 3DP component 3 for supporting the 3DP component. Preferably, the cushion block 1 can be set at a position where the 3DP component 3 has a gentle protrusion or a concave pit, so that the position of the cushion block 1 and the component can remain relatively still during the subsequent lifting process. For example, when the cushion block 1 is set at a gentle protrusion position of the 3DP component, at this time, the upper end surface of the cushion block 1 is correspondingly set to a concave pit that matches the protrusion, so that the concave pit and the protrusion can make the cushion block 1 and the 3DP component relatively locked and will not move after the cooperation, thereby preventing the 3DP component from being damaged during the lifting process; accordingly, when the cushion block 1 is set at the concave pit position of the 3DP component 3, the upper end surface of the cushion block 1 should be set to a protrusion that matches the concave pit, so that the protrusion at the upper end of the cushion block 1 can be locked with the concave pit of the 3DP component 3, so that the cushion block 1 and the 3DP component can remain relatively still. The cushion block 1 and the 3DP component 3 are printed together, and a certain gap is reserved between the cushion block 1 and the 3DP component. The adjustable platform 2 is placed on the lower end surface of the cushion block 1 after printing is completed. In the present invention, during the process of 3DP component process design, according to the structural characteristics of the component, a support surface that can be supported by the cushion block 1 is found. When designing the cushion block 1, the upper end surface of the cushion block 1 is designed to follow the support surface, thereby ensuring that the upper end surface of the cushion block 1 and the support surface can be locked, and the cushion block 1 and the 3DP component can remain relatively still during the transportation of the 3DP component 3. In the design process, a certain gap is reserved between the 3DP component 3 and the cushion block 1 to ensure that the 3DP component 3 and the cushion block 1 will not stick together during the printing process. After the design is completed, the design models of the 3DP component 3 and the cushion block 1 are imported into the 3D printer for printing. It should be noted that during the printing process, a certain space should be reserved at the bottom of the cushion block 1, so that the adjustable platform 1 can be inserted into the bottom of the cushion block 1 after printing is completed, thereby completing the transportation of the 3DP component through the supporting effect of the adjustable platform 3 and the cushion block 1.

[0027] In the specific operation of a variable structure fast lifting device of the present invention, firstly, the 3DP component 3 and the cushion block 1 supporting the 3DP component 3 are printed together. Note that during the printing process, a space is reserved at the bottom of the cushion block 1 for the adjustable platform 2 to be inserted. After the printing is completed, the excess sand is removed. During the sand removal process, it is noted that the sand in the gap reserved between the 3DP component 3 and the cushion block 1 is not removed first. During the printing process, the sand in the gap will also penetrate into the adhesive at the upper and lower parts thereof. Therefore, during the sand removal process, the sand in the gap will also remain relatively stable and will not be blown away by the sand blowing device. In addition, the sand at the bottom of the cushion block 1 is not removed. After the excess sand is removed, the adjustable platform 1 is inserted into the bottom of the cushion block 1 from the side, so that the bottom of the cushion block 1 and the upper surface of the adjustable platform 2 are stably matched, and then the 3DP component can be transported by the lifting device. In order to ensure the stability of the transportation process, 3 to 4 cushion blocks 1 are usually set to ensure the stability of the 3DP component during transportation. The device of the present invention can print a cushion block 1 that stably cooperates with the 3DP component according to the shape of the 3DP component, and the cushion block 1 is detachably connected to the adjustable platform 2, so that the adjustable platform 2 can transport 3DP components of various shapes and specifications. The lifting device can be quickly disassembled to facilitate the transportation of large 3DP components, and the cushion block printed in the shape makes the entire lifting device and the 3DP component self-locking as a whole, without the need to set up other structures to clamp the 3DP component and the cushion block, thereby reducing the difficulty and cost of transportation.

[0028] The upper end surface of the adjustable platform 2 is provided with a boss, and the lower end surface of the cushion block 1 is reserved with a groove that matches the boss. That is, when designing the model of the cushion block 1, a groove that matches the boss is reserved in advance. After printing is completed, when the adjustable platform is inserted into the bottom of the cushion block 1, it is only necessary to insert the boss on the upper end surface of the adjustable platform 2 into the groove reserved at the bottom of the cushion block 1, so that the adjustable platform 2 can be stably engaged with the bottom of the cushion block 1. Preferably, the boss can be set as a dovetail protrusion, and correspondingly, the groove is set as a dovetail groove that matches the dovetail protrusion, so that the boss is engaged with the groove, and the boss will not slip out of the groove during the lifting process.

[0029] In a second embodiment of the present invention, Figure 1As shown, the adjustable platform 2 includes two side positioning plates 21 and a platform 22 connected to the inner side of the side positioning plates 21, wherein the two side positioning plates 21 are connected by a transfer rod 23. In this embodiment, the bottom of the cushion block 1 is supported by the platform 22. A plurality of circular holes 211 are provided on the side positioning plates 21, and the transfer rod 23 passes through the circular holes 211 to connect the two side positioning plates. The number of platforms 22 can be set according to the number of cushion blocks 1. For example, if there are four cushion blocks 1, two platforms 22 are respectively connected to the inner side of the two side positioning plates 21. During the specific operation, each side positioning plate and the platform 22 connected thereto are inserted into the bottom of the corresponding cushion block 1, and the side positioning plates 21 on both sides are aligned, and the transfer rod 23 is sequentially passed through the circular holes on the side positioning plates 21 on both sides to complete the relative fixation of the side positioning plates 21 on both sides, so as to facilitate the lifting and transportation of 3DP components.

[0030] like Figure 2 As shown, the platform 22 is configured as an inverted U-shaped structure, the upper end surface of the inverted U-shaped structure is supported on the bottom of the cushion block 1 , and the width of the side positioning plate 21 is greater than the width of the platform 22 .

[0031] Furthermore, if Figure 3 As shown, a notch 221 is provided at the lower end of the two side walls of the inverted U-shaped structure. Preferably, the notch 221 can be set as a U-shaped notch or a semicircular notch. The notch 221 is cooperated with a support rod 24 which is perpendicular to the extension direction of the transfer rod 23, wherein the lower part of the support rod 24 is tangent to the upper part of the transfer rod 23. Through the supporting effect of the support rod 24, the entire lifting device is more stable during the process of transferring 3DP components.

[0032] The present invention provides a rapid transportation method for 3DP components, using a rapid lifting device with a variable structure as described above, and the transportation method comprises the following steps:

[0033] The first step is to print the 3DP component 3 and the cushion block 1 together;

[0034] The second step is to insert the adjustable platform 2 into the lower end surface of the cushion block 1;

[0035] The third step is to transport the 3DP component 3 via the adjustable platform 2 .

[0036] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
