[0030] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0031] The sample delivery device 100 of the embodiment of the present invention includes a support assembly 1 and a lifting assembly 2. The support assembly 1 includes a support frame 11 and a support screw 12. The inner side surface of the support frame 11 extends in a direction from top to bottom and is arranged obliquely in a direction away from the outer side surface of the support frame 11. The inner side surface of the support frame 11 is used to cooperate with the inclined surface of the bottom of the sample 1000. The support frame 11 is slidable. The support screw 12 extends in the up-down direction and is connected to the support frame 11. The support screw 12 can rotate in the up-down direction relative to the support frame 11 to drive the support frame 11 to move in the up-down direction. The lifting assembly 2 includes a lifting rod 21. One end of the lifting rod 21 is connected to the support frame 11, and the other end of the lifting rod 21 extends out of the support frame 11. The lifting rod 21 is used to be connected to the lifting device.

[0032] Specifically, Figure 1-Figure 4 As shown, the inner side surface of the support frame 11 is an inclined surface, that is, the support space in the support frame 11 gradually decreases from top to bottom in the vertical direction. By cooperating between the inner side surface of the support frame 11 and the inclined surface at the bottom of the sample 1000, the sample 1000 can be stably mounted on the support frame 11, and the sample 1000 can be moved by sliding the support frame 11. The lower end of the support screw 12 is connected to the support frame 11. When the support screw 12 rotates in the vertical direction, it drives the support frame 11 to move in the vertical direction. The setting of the support screw 12 facilitates the adjustment of the position of the support frame 11 in the vertical direction, thereby achieving the adjustment of the position of the sample 1000 in the vertical direction, and facilitating the rise and fall of the sample 1000.

[0033] For example, the support frame 11 can be rectangular, square, or circular, and the shape of the support frame 11 can be set differently according to the shape of the sample 1000, so that the support frame 11 can stably support samples 1000 of various shapes. Since the size and shape of the support frame 11 can be set differently according to the size and shape of the sample 1000, the support frame 11 can adapt to the installation of samples 1000 of different sizes and weights.

[0034] For example, a pulley or roller may be provided under the support frame 11 to facilitate the movement of the support frame 11 , or to cooperate with the sliding assembly 200 of the sample delivery system to realize the movement of the support frame 11 .

[0035] The sample delivery device 100 of the embodiment of the present invention sets the inner side surface of the support frame 11 as an inclined surface, which is convenient for matching with the chamfered inclined surface at the bottom of the sample 1000, thereby improving the stability of the sample 1000. The lifting rope of the lifting device is hung on the lifting rod 21, so that the support frame 11 and the sample 1000 are conveniently lifted to the specified position of the test system, and the sample 1000 is moved into the test system by sliding the support frame 11, and then the position of the support frame 11 in the up and down directions is adjusted by the support screw 12 to realize the rising and falling of the sample 1000. Since the support frame 11 and the sample 1000 are matched with each other through the inclined surface, the sample 1000 is installed on the test platform by moving the support frame 11 and the sample 1000 downward, thereby completing the installation of the sample 1000. The structure is simple, and no complicated driving components are required, thereby reducing the cost of the sample delivery device 100.

[0036] Furthermore, the sample delivery device 100 in this embodiment can realize the lifting function by setting a lifting rod 21, so as to facilitate lifting the support frame 11 and the sample 1000 to the height of the test platform of the test system, and then slide the support frame 11 and the sample 1000 to the top of the test platform.

[0037] Furthermore, the sample delivery device 100 of this embodiment realizes the lifting function through the lifting rod 21, and realizes the sample delivery and self-lifting functions through the support frame 11 and the support screw 12. It does not need to be equipped with an auxiliary power system. It has a simple and practical structure and low cost, and can realize the rapid installation of large-size and high-weight model specimens 1000 in the test system.

[0038] In some embodiments, the support frame 11 includes multiple support beams 111, which are detachably connected end to end to form the support frame 11, and the inner side surfaces of the support beams 111 extend from top to bottom and are inclined away from the outer side surfaces of the support beams 111.

[0039] Specifically, Figure 1-Figure 4 As shown, the multiple support beams 111 are detachably connected to facilitate installation of the support frame 11 at the bottom of the sample 1000. At the same time, when the sample 1000 is installed on the test platform, the support beams 111 can be easily removed from the bottom of the sample 1000.

[0040] For example, there are three support beams 111 connected end to end to form a triangle, which can accommodate a triangular sample 1000. There are four support beams 111 connected end to end to form a rectangle, which can accommodate a rectangular sample 1000.

[0041] In some embodiments, the plurality of support beams 111 include a first support beam 1111, a second support beam 1112, a third support beam 1113 and a fourth support beam 1114, the first support beam 1111 and the third support beam 1113 are relatively arranged in a first direction, the first direction is orthogonal to the up-down direction, the second support beam 1112 and the fourth support beam 1114 are relatively arranged in a second direction, the second direction is orthogonal to the first direction and the up-down direction.

[0042] Specifically, Figure 1-Figure 4 As shown, the first support beam 1111, the second support beam 1112, the third support beam 1113 and the fourth support beam 1114 are detachably connected end to end to form a support frame 11. The inner side surfaces of the first support beam 1111, the second support beam 1112, the third support beam 1113 and the fourth support beam 1114 are all inclined surfaces, which are used to cooperate with the four chamfered inclined surfaces at the bottom of the sample 1000 respectively.

[0043] Optionally, both ends of each support beam 111 in its extension direction may also be set as inclined surfaces, and the inclined surfaces of two adjacent support beams 111 cooperate to facilitate the connection of two adjacent support beams 111. For example, two adjacent support beams 111 are connected by bolts to facilitate the connection and separation of the support beams 111.

[0044] In some embodiments, the support assembly 1 also includes a support cantilever 13, one end of the support cantilever 13 is connected to the upper end surface of the support beam 111, and the other end of the support cantilever 13 extends out of the support frame 11 and is connected to the support screw 12. The support screw 12 can rotate in the up and down directions relative to the support cantilever 13 to drive the support cantilever 13 to move in the up and down directions.

[0045] Specifically, Figure 1-Figure 4 As shown, the support cantilever 13 is located on the support beam 111, and the support cantilever 13 extends along the second direction. The lower end surface of one end of the support cantilever 13 is connected to the upper end surface of the support beam 111, and the other end of the support cantilever 13 extends out of the support beam 111. The other end of the support cantilever 13 is provided with a threaded hole, and the support screw 12 is connected to the support cantilever 13 through the threaded hole. The support frame 11 is raised and lowered by rotating the support screw 12.

[0046] Optionally, the supporting cantilever 13 and the supporting beam 111 are connected by bolts.

[0047] In some embodiments, the support cantilever 13 includes a first support cantilever 131 and a second support cantilever 132. The first support cantilever 131 is arranged at at least one end of the first support beam 1111 in its extension direction, and the second support cantilever 132 is arranged at at least one end of the third support beam 1113 in its extension direction.

[0048] Specifically, Figure 1-Figure 4 As shown, there are two first support cantilevers 131, and the two first support cantilevers 131 are respectively arranged at the two ends of the first support beam 1111 in its extension direction; there are two second support cantilevers 132, and the two second support cantilevers 132 are respectively arranged at the two ends of the third support beam 1113 in its extension direction; accordingly, there are four support screws 12, and the four support screws 12 are respectively connected to the two first support cantilevers 131 and the two second support cantilevers 132 in a one-to-one correspondence, so that the support frame 11 and the sample 1000 can move smoothly in the up and down directions, thereby improving the safety of the sample 1000.

[0049] In some embodiments, the lifting assembly 2 further includes a vertical rod 22 extending in the up-down direction, one end of the vertical rod 22 is detachably connected to the support beam 111 , and the other end of the vertical rod 22 is connected to one end of the lifting rod 21 .

[0050] Specifically, Figure 1-Figure 4 As shown, the lower end of the vertical pole 22 is detachably connected to the support beam 111, and the upper end of the vertical pole 22 is connected to the lifting rod 21. By setting the vertical pole 22 and the lifting rod 21, the hook mounting point of the lifting device is transferred to above the sample 1000 to prevent the lifting rope from squeezing the sample 1000 and thus damaging the sample 1000.

[0051] Furthermore, since the vertical pole 22 and the support beam 111 are detachably connected, it is convenient to install the vertical pole 22 when the sample 1000 needs to be lifted to realize the lifting function, and to remove the vertical pole 22 when the sample 1000 does not need to be lifted to avoid the vertical pole 22 affecting the test work of the sample 1000.

[0052] Optionally, both ends of the vertical pole 22 are provided with threads, the support beam 111 is provided with threaded holes, and the lower end of the vertical pole 22 is connected to the support beam 111 through the threaded holes.

[0053] Optionally, there are four vertical poles 22, two of which are arranged at both ends of the first support beam 1111, and the other two vertical poles 22 are arranged at both ends of the third support beam 1113. The arrangement of four vertical poles 22 facilitates the lifting device to lift the support frame 11.

[0054] In some embodiments, the lifting assembly 2 also includes a ring beam 23, which is arranged at intervals with the support frame 11 in the up and down directions, and the ring beam 23 is detachably connected to the other end of the vertical pole 22, and one end of the lifting rod 21 is connected to the outer peripheral surface of the ring beam 23 and extends in a direction away from the ring beam 23.

[0055] Specifically, Figure 1-Figure 4As shown, the ring beam 23 is provided with a threaded hole that matches the vertical pole 22 and is threadedly connected to the vertical pole 22. The ring beam 23 is formed by welding four square beams, two of which extend out of the ring beam 23 to form a lifting rod 21, so that the lifting rope of the lifting device is hung on the lifting rod 21. By setting the vertical pole 22, the ring beam 23 and the lifting rod 21, the hook mounting point of the lifting device is transferred to the top of the model sample 1000.

[0056] Optionally, the lifting assembly 2 further includes a connecting piece, which is threadedly connected to the vertical pole 22 and is located above the ring beam 23, for example, the connecting piece is a nut.

[0057] The sample delivery system of the embodiment of the present invention includes the sample delivery device 100 of the above embodiment. Since the sample delivery system includes the sample delivery device 100, a large-sized and heavy sample 1000 can be installed in the test system.

[0058] In some embodiments, the sample delivery system also includes a sliding assembly 200, which includes a slide rail 210 and a slider 220 fitted on the slide rail 210, the slide rail 210 includes a first slide rail 2110 and a second slide rail 2120, the first slide rail 2110 and the second slide rail 2120 are arranged at intervals in the first direction and are arranged relative to the support frame 11 in the up and down directions, the first direction is orthogonal to the up and down directions, one end of the slide rail 210 is suitable for extending into the test system, and the support screw 12 is detachably connected to the slider 220 to drive the support screw 12 to slide along the first direction.

[0059] Specifically, Figure 1-Figure 4 As shown, the slide rail 210 extends along the second direction, the first slide rail 2110 and the second slide rail 2120 are arranged in parallel in the first direction, the upper end surface of the slider 220 is provided with a groove, and one end of the support screw 12 can be connected to the slider 220 through the groove. By respectively arranging two sliders 220 on the first slide rail 2110 and the second slide rail 2120, and by the four sliders 220 cooperating with the four support screws 12 respectively, it is convenient for the slider 220 to slide with the support frame 11 and the sample 1000 on the slide rail 210 to slide the sample 1000 to the top of the test platform, and the sample 1000 is installed on the test platform by rotating the support screw 12, thereby completing the installation of the sample 1000.

[0060] The sample delivery method of the embodiment of the present invention includes installing a support frame at the bottom of the sample and cooperating with the inclined surface of the bottom of the sample, wherein the inner side surface of the support frame extends in a direction from top to bottom and is arranged obliquely in a direction away from the outer side surface of the support frame; using a lifting device to lift the lifting rod, the lifting rod is arranged on a ring beam, and the ring beam is detachably connected to the support frame through a vertical rod; lifting the sample and the support frame onto a slide rail, connecting the slider on the slide rail with a support screw, rotating the support screw to separate the support frame from the slide rail to suspend the sample, and sliding the sample onto the sample platform, wherein the support screw extends in an up-and-down direction and is connected to the support frame, and the support screw can rotate around the up-and-down direction relative to the support frame to drive the support frame to move in the up-and-down direction; separating the vertical rod from the support frame, rotating the support screw to move the sample and the support frame downward until the support frame abuts against the slide rail and the sample moves to the test platform; separating the support frame from the sample and moving it out of the test system to complete the installation of the sample.

[0061] According to the sample delivery method of the embodiment of the present invention, the first support beam, the second support beam and the third support beam are first connected in sequence. Since the first support beam and the third support beam are arranged at intervals in the first direction, the first support beam, the second support beam and the third support beam form a support frame with one end open. Support cantilevers are respectively installed at both ends of the first support beam and the third support beam in their extension directions. At least a portion of the support cantilever is located outside the support frame and is threadedly connected to the support screw.

[0062] Secondly, the open end of the support frame with one end open is moved toward the sample to push the support frame to the bottom of the sample, and then the fourth support beam is respectively formed with the first support beam and the third support beam to form a complete support frame. Since the inner side surface of the support beam extends from top to bottom and is inclined away from the outer side surface of the support beam, the inner side surface of the support beam cooperates with the chamfered surface of the bottom of the sample, so that the inner side surface of the support frame can fit with the bottom of the sample.

[0064] Finally, after separating the ring beam and the vertical pole from the support frame, use the slider to slide the specimen and the support frame to the top of the test platform, rotate the support screw to make the support frame abut against the slide rail, and move the specimen downward onto the test platform. Then separate the support screw from the slider, separate the second support beam or the fourth support beam from the support frame, and remove the support beam from the bottom of the specimen to complete the installation of the specimen.
