DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The following is combined with Figure 1-Figure 11 The specific implementation modes of the present invention are described in further detail.

[0034] Depend on Figure 1-Figure 11 The present invention comprises a ground rail 1 and a conveying frame 2. In order to facilitate the stacking of the conveying frame 2, a sliding frame 3 is symmetrically fixedly connected to the lower side of the conveying frame 2 at the front and rear sides. Two conveying wheels 4 that can move left and right are arranged inside each of the sliding frames 3. The moving directions of the two conveying wheels 4 in each of the sliding frames 3 are opposite, and the moving distances of the two relative to the sliding frame 3 are the same. A stacking guide rail 5 is fixedly connected to the left and right sides of the conveying frame 2. A rotatable lifting guide rail 6 is arranged on the front and rear sides of each lifting guide rail 6. The lower end of each lifting guide rail 6 is matched with the corresponding stacking guide rail 5. A supporting frame 7 is fixedly connected to the inside of the conveying frame 2. A plurality of supporting mechanisms 8 are rotatably connected to the middle part of the supporting frame 7.

[0035] It should be noted that due to the limitation of the factory site, some areas have restrictions on the distance between the two ground rails 1, and due to the difference in installation accuracy, the relative distance between the two ground rails 1 will also change. Therefore, by using two conveying wheels 4 that can move in opposite directions, the installation difficulty between the two ground rails 1 can be reduced, and the installation restrictions of the ground rails 1 in different sites can also be adapted.

[0036] When in use, the material can be supported by the supporting mechanism 8. During normal use, the conveying frame 2 can be moved by the cooperation of the conveying wheels 4 and the ground rail 1, and then the material is supported and transported by the supporting mechanism 8. At this time, the lower end of the lifting guide rail 6 is placed inside the ground rail 1. When the lifting guide rail 6 moves with the conveying frame 2, the debris inside the ground rail 1 can be cleaned to increase the movement stability of the conveying frame 2. When the material is transported, multiple conveying frames 2 can be stacked, thereby reducing the footprint of multiple conveying frames 2. When stacking is required, for the convenience of explanation, the stacked upper and lower conveying frames 2 are simply defined as the upper conveying frame 2 and the lower conveying frame 2. When stacking, each supporting mechanism 8 of the upper conveying frame 2 can be rotated and retracted relative to its supporting frame 7, and then the four lifting guide rails 6 at the front and rear ends of the upper conveying frame 2 can be rotated and retracted, so that the conveying wheels 4 of the upper conveying frame 2 can be pushed into the stacking guide rail 5 through the lifting guide rail 6 of the lower conveying frame 2, and the stacking of the two conveying frames 2 is completed.

[0037] Further, by Figure 1 , Figure 2 and Figure 5 It is given that in order to make the center of gravity of the device more stable during transportation, the conveying wheel 4 includes a wheel frame 9 and a rolling wheel 10, and the rolling wheel 10 is adapted to the lifting guide rail 6, the stacking guide rail 5, and the ground rail 1. A sliding block 11 is fixedly connected to the upper side of each wheel frame 9, and a sliding groove 12 adapted to the sliding block 11 is opened on the lower side of each sliding frame 3. A synchronous gear 13 is rotatably connected to the middle part of each sliding groove 12, and a long rack 14 is fixedly connected to the side of each sliding block 11 close to the synchronous gear 13. The two long racks 14 in the same sliding groove 12 are respectively meshed with the upper and lower sides of the corresponding synchronous gear 13;

[0038] It should be noted that the middle part of the lifting guide rail 6 is tilted outward. When the conveying wheel 4 enters the stacking guide rail 5 along the lifting guide rail 6, the two conveying wheels 4 will move away from each other. Since the relative displacement distances of the two conveying wheels 4 relative to the sliding frame 3 are the same, the overall center of the conveying frame 2 will not be offset, and the center of gravity can always be kept stable. The cross-sections of the lifting guide rail 6, the stacking guide rail 5, and the ground rail 1 are all in a "concave" shape, which can enable the rolling wheel 10 to roll therein, and a lateral force can be applied to the rolling wheel 10 to cause the sliding block 11 to move relative to the sliding frame 3.

[0039] During use, when lateral force is applied to the rolling wheel 10 under the action of the lifting guide rail 6, the stacking guide rail 5 or the ground rail 1, the corresponding wheel frame 9 and the sliding block 11 will be driven to move along the sliding groove 12, and then the long rack 14 will be driven to move. Since the two long racks 14 are engaged with the synchronous gear 13 together, the moving distances of the two long racks 14 are the same, thereby achieving the purpose of achieving the same moving distances of the two sliding blocks 11 in the same sliding groove 12.

[0040] Further, by Figure 2-Figure 9 In order to make the device run more stably, each of the sliding blocks 11 is provided with a first through slot 15, each of the long racks 14 is provided with a support slot 16 that runs through the front and rear, and the upper and lower sides of the synchronous gear 13 are provided with two support blocks 17 that are fixedly connected to the sliding slot 12, and each support block 17 is slidably connected to the corresponding support slot 16, and each of the sliding blocks 11 is fixedly connected to a push handle 18 on one side away from the corresponding long rack 14, and each of the sliding frames 3 is provided with a second through slot 19 on the left and right sides for the push handle 18 to pass through;

[0041] It should be noted that the positions of the two first through slots 15 correspond to the cross-sectional positions of the two long racks 14, respectively, so that when the two sliding blocks 11 move toward each other, there will be no interference between the long racks 14 and the sliding blocks 11; under the mutual cooperation of the support block 17 and the support slot 16, the two long racks 14 can always maintain a good meshing state with the synchronous gear 13;

[0042] During use, when the two rolling wheels 10 pass through the lifting guide rail 6, they will move away from each other. At this time, each pushing handle 18 will extend from the corresponding second through groove 19, making it convenient for the staff to apply moving force to the conveying frame 2 by pushing the handle 18, thereby facilitating the staff's operation.

[0043] Further, by Figure 2-Figure 7It is given that, in order to facilitate the folding of each lifting guide rail 6, each of the sliding frames 3 is fixedly connected to a side of the corresponding lifting guide rail 6 with an extension platform 20, and a guide column 21 is fixedly connected to the upper side of each extension platform 20. A lifting sleeve 22 is sleeved on the outer side of each guide column 21, and each lifting sleeve 22 is fixedly connected to the corresponding lifting guide rail 6. A guide groove 23 is provided on the outer side of each guide column 21, and a guide block 24 adapted to the guide groove 23 is fixedly connected to the interior of each lifting sleeve 22;

[0044] During use, when the lifting guide rail 6 needs to be retracted from the ground rail 1, an upward force can be applied to the lifting sleeve 22, and the lifting sleeve 22 moves upward along the guide column 21. At this time, the guide block 24 slides upward along the guide groove 23, thereby causing the lifting guide rail 6 to disengage from the ground rail 1.

[0045] Further, by Figure 7 It is given that the guide groove 23 includes a lifting portion 25 and a rotating portion 26, the upper end of the lifting portion 25 is connected to the rotating portion 26, and the horizontal rotation angle of the rotating portion 26 is 90°;

[0046] During use, when the guide block 24 passes the lifting part 25, the lifting guide rail 6 gradually disengages from the ground rail 1. When the guide block 24 passes the rotating part 26, it drives the lifting guide rail 6 to rotate 90° toward the side close to the conveying rack 2, and the lifting guide rail 6 is folded close to the front and rear sides of the conveying rack 2.

[0047] Further, by Figure 2-Figure 7 It is given that, in order to make the lifting guide rail 6 more stably fixed, a limiting hole 27 is provided on the side of each guide column 21, a first return spring 28 is fixedly connected to the inside of each limiting hole 27, a first limiting block 29 is fixedly connected to the outside of the first return spring 28, a limiting through groove 30 is provided on the side wall of each lifting sleeve 22 corresponding to the position of the first limiting block 29, a top block 31 slidably connected to the limiting through groove 30 is provided on the side of each first limiting block 29 close to the limiting through groove 30, a power spring 32 is provided inside each lifting sleeve 22, the upper side of the power spring 32 abuts against the lifting sleeve 22, and the lower side of the power spring 32 abuts against the extension platform 20;

[0048] During use, when the lifting guide rail 6 and the ground rail 1 are in a mating state, the first limit block 29 and the limit slot 30 cooperate with each other to limit the lifting sleeve 22. When the lifting guide rail 6 needs to be retracted, the top block 31 can be pushed. The top block 31 pushes the first limit block 29 to move along the limit hole 27 in the direction of the first return spring 28, so that the first limit block 29 is disengaged from the limit slot 30. At this time, the lifting sleeve 22 is driven upward by the action of the power spring 32 to retract the lifting guide rail 6.

[0049] Further, by Figure 2-Figure 7 It is given that in order to be able to fix and limit the upper conveying frame 2, each of the sliding blocks 11 is fixedly connected to a first connecting plate 33 on one side close to the corresponding synchronous gear 13, each of the first connecting plates 33 is fixedly connected to a second connecting plate 34 on one side close to the corresponding lifting sleeve 22, each of the lifting sleeves 22 is fixedly connected to a second limiting block 35 on one side away from the corresponding lifting guide rail 6, each of the second connecting plates 34 is fixedly connected to a second matching block 36 adapted to the second limiting block 35, and a stacking limiting plate 37 is fixedly connected to the upper side of the second connecting plate 34, and a manual cross bar 38 is respectively provided on the front and rear sides of the conveying frame 2, and the left and right sides of each manual cross bar 38 are rotatably connected to the corresponding lifting sleeve 22;

[0050] When in use, when the sliding block 11 moves, it will drive the second connecting plate 34 to move through the first connecting plate 33. When the lifting guide rail 6 is in the retracted state, each second limit block 35 is in a position close to the conveying frame 2. When the two conveying wheels 4 move away from each other, the second matching block 36 will gradually approach the corresponding second limit block 35 to limit the reverse rotation of the second limit block 35. At the same time, the stacking limit plate 37 will move to the upper side of the stacking guide rail 5 with the second connecting plate 34 to limit the conveying wheel 4 on the upper side of the stacking guide rail 5, thereby increasing the stability of the stacking device. When the lifting guide rail 6 needs to be unfolded, first ensure that the conveying wheel 4 is located on the ground rail 1. At this time, the second matching block 36 does not cooperate with the second limit block 35. Pressing the manual cross bar 38 downward will drive the corresponding lifting sleeve 22 to move downward until the first limit block 29 cooperates with the limiting through groove 30 to complete the unfolding of the lifting guide rail 6.

[0051] Further, by Figure 8-Figure 11In order to facilitate the operation of the staff, a rotatable power shaft 39 is symmetrically arranged inside the conveying frame 2, and a square rod 40 is fixedly connected to the front and rear sides of each power shaft 39. A power rod 41 threadedly connected to the conveying frame 2 is arranged on the front and rear sides of each power shaft 39. The front and rear sides of each power shaft 39 are slidably connected to the corresponding power rod 41 through the square rod 40. A connecting shaft 42 is arranged between the two power shafts 39, and the left and right sides of the connecting shaft 42 are fixed. A first bevel gear 43 is connected, and a second bevel gear 44 meshing with the first bevel gear 43 is fixedly connected to the middle of each power shaft 39, and a power gear 45 is fixedly connected to the middle of each power shaft 39, and a power rack 46 is meshed on the upper side of each power gear 45, and a pressing hole is opened at the position of each power rack 46 of the conveying frame 2, so that the staff can press the power rack 46 through the pressing hole, and a second return spring 47 is provided on the upper side of each power rack 46;

[0052] During use, when it is necessary to lift the lifting guide rail 6, any power rack 46 can be directly pressed. At this time, the power rack 46 drives the corresponding power shaft 39 to rotate through the power gear 45. Under the action of the first bevel gear 43, the second bevel gear 44 and the connecting shaft 42, the two power shafts 39 will rotate together. When the power shaft 39 rotates, it will drive the power push rod 41 to rotate through the square rods 40 on its front and rear sides. Since the power push rod 41 is threadedly connected to the conveying frame 2, the power push rod 41 will move toward the direction of the corresponding top block 31 while rotating. When the power push rod 41 presses the top block 31, each lifting guide rail 6 can be lifted. At this time, the corresponding power rack 46 is released, and each power rack 46 is reset under the action of the corresponding second reset spring 47.

[0053] Further, by Figure 8-Figure 11 It is given that, in order to facilitate the folding of the support mechanism 8, the support frame 7 is internally rotatably connected to two transverse shafts 48, the lower side of each of the support mechanisms 8 is fixedly connected to the corresponding transverse shaft 48, the left and right ends of each of the transverse shafts 48 are fixedly connected to a third bevel gear 49, the upper side of each third bevel gear 49 is meshed with a fourth bevel gear 50, the upper side of each fourth bevel gear 50 is fixedly connected to an adjusting rod 51, the upper side of each adjusting rod 51 is slidably sleeved with an adjusting knob 52, each adjusting knob 52 is provided with a tension spring 53 inside, and the lower side of each adjusting knob 52 is fixedly connected to a plurality of limiting protrusions 54, and the upper side of the conveying frame 2 is provided with limiting grooves 55 corresponding to the limiting protrusions 54 one by one;

[0054] During use, when the support mechanism 8 needs to be folded up, the adjusting knob 52 can be pulled up. At this time, the limiting protrusion 54 and the limiting groove 55 are disengaged, and the adjusting knob 52 can be rotated. At this time, rotating the adjusting knob 52 drives the adjusting rod 51 to rotate, and then drives the third bevel gear 49 to rotate through the fourth bevel gear 50, so that the corresponding transverse rotating shaft 48 rotates, thereby driving the support mechanism 8 to rotate and fold.

[0055] Further, by Figure 8-Figure 11 It is given that in order to be able to adjust the support position, the support mechanism 8 includes a rotating block 56 fixedly connected to the corresponding horizontal rotating shaft 48, a large turntable 57 is rotatably connected to the upper side of the rotating block 56, a support rod 58 is eccentrically fixedly connected to the upper side of the large turntable 57, and a fulcrum 59 is fixedly connected to the upper side of the support rod 58. Furthermore, a fixing pin and a plurality of fixing holes are provided between the large turntable 57 and the rotating block 56, so that the large turntable 57 can be adjusted and fixed at multiple angles relative to the rotating block 56;

[0056] When in use, by rotating the large turntable 57, the position of the fulcrum 59 can be adjusted due to the eccentric setting between the support rod 58 and the large turntable 57, so as to facilitate the support and transportation of materials of different types.

[0057] When the present invention is used, the material can first be supported by the support mechanism 8. During normal use, the conveying frame 2 can be moved by the cooperation between the conveying wheel 4 and the ground rail 1, and then the material can be supported and transported by the support mechanism 8. At this time, the lower end of the lifting guide rail 6 is placed inside the ground rail 1. When the lifting guide rail 6 moves with the conveying frame 2, the debris inside the ground rail 1 can be cleaned, thereby increasing the moving stability of the conveying frame 2.

[0058] When the material transportation is completed, multiple conveying racks 2 can be stacked and placed, thereby reducing the floor space of multiple conveying racks 2. When stacking is required, for the convenience of explanation, the stacked upper and lower conveying racks 2 are simply defined as the upper conveying rack 2 and the lower conveying rack 2. When stacking, any power rack 46 of the upper conveying rack 2 can be directly pressed. At this time, the power rack 46 drives the corresponding power shaft 39 to rotate through the power gear 45. Under the action of the first bevel gear 43, the second bevel gear 44 and the connecting shaft 42, the two power shafts 39 will rotate together. When the power shaft 39 rotates, it will drive the power support rod 41 to rotate through the square rods 40 on its front and rear sides. Since the power support rod 41 is threadedly connected to the conveying rack 2, the power support rod 41 will move toward the direction of the corresponding top block 31 while rotating. When the power support rod 41 presses the top block 31, the top block 31 pushes the first limit block 29 to move along the limit hole 27 in the direction of the first return spring 28, so that the first limit block 29 is disengaged from the limit slot 30. At this time, the lifting sleeve 22 is driven to move upward under the action of the power spring 32. At this time, the guide block 24 slides upward along the guide slot 23, thereby disengaging the lifting guide rail 6 from the ground rail 1 and bringing the lifting guide rail 6 close to the front and rear sides of the conveying frame 2 for retracting, releasing the corresponding power rack 46, and each power rack 46 is reset under the action of the corresponding second return spring 47. Then, the four lifting guide rails 6 at the front and rear ends of the upper conveying frame 2 are rotated and retracted, so that the conveying wheel 4 of the upper conveying frame 2 can be pushed into the stacking guide rail 5 through the lifting guide rail 6 of the lower conveying frame 2, thereby completing the stacking of the two conveying frames 2.

[0059] Afterwards, the lifting guide rail 6 of the lower conveying frame 2 is folded up in the same way, and it can be stacked again as the upper conveying frame 2. After stacking, the stacking limit plate 37 will move to the upper side of the stacking guide rail 5 along with the second connecting plate 34, and limit the conveying wheel 4 on the upper side of the stacking guide rail 5, thereby increasing the stability of the stacking device.

[0060] The present invention has a novel structure, ingenious conception, and simple and convenient operation.
