[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] The following is in conjunction with the appendix Figures 1-11 The specific embodiments of the present invention will be described in further detail below.

[0034] Depend on Figures 1-11 The present invention includes a ground rail 1 and a conveyor frame 2. To facilitate the stacking of the conveyor frame 2, a sliding frame 3 is fixedly connected symmetrically to the lower side of the conveyor frame 2. Each sliding frame 3 has two left and right movable conveyor wheels 4 inside. The two conveyor wheels 4 in each sliding frame 3 move in opposite directions and move the same distance relative to the sliding frame 3. A stacking guide rail 5 is fixedly connected to the left and right sides of the conveyor frame 2. Each lifting guide rail 6 has a rotatable lifting guide rail 6 on its front and rear sides. The lower end of each lifting guide rail 6 is adapted to the corresponding stacking guide rail 5. A support frame 7 is fixedly connected inside the conveyor frame 2. Multiple support mechanisms 8 are rotatably connected to the middle of the support frame 7.

[0035] It should be noted that due to the limitations of the factory site, there are restrictions on the distance between the two ground rails 1 in some areas. Moreover, due to different installation precision, the relative distance between the two ground rails 1 will also change. Therefore, by using two conveyor 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] In use, the material can be supported by the support mechanism 8. During normal use, the conveyor frame 2 can be moved by the cooperation of the conveyor wheel 4 and the ground rail 1, and 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 conveyor frame 2, it can clean up the debris inside the ground rail 1 and increase the movement stability of the conveyor frame 2. After the material is conveyed, multiple conveyor frames 2 can be stacked to reduce the floor space occupied by multiple conveyor frames 2. When stacking is required, for ease of explanation, the two conveyor frames 2 after stacking are simply defined as the upper conveyor frame 2 and the lower conveyor frame 2. When stacking, each support mechanism 8 of the upper conveyor frame 2 can be rotated and retracted relative to its support frame 7. Then, the four lifting guide rails 6 at the front and rear ends of the upper conveyor frame 2 can be rotated and retracted. Then, the conveyor wheel 4 of the upper conveyor frame 2 can be pushed into the stacking guide rail 5 through the lifting guide rail 6 of the lower conveyor frame 2, thus completing the stacking of the two conveyor frames 2.

[0037] Furthermore, by Figure 1 , Figure 2 and Figure 5 To make the center of gravity more stable during device transportation, the conveying wheel 4 includes a wheel frame 9 and a rolling wheel 10. 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. 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 of each sliding groove 12. A long rack 14 is fixedly connected to the side of each sliding block 11 near the synchronous gear 13. The two long racks 14 inside the same sliding groove 12 mesh with the upper and lower sides of the corresponding synchronous gear 13, respectively.

[0038] It should be noted that the middle part of the lifting guide rail 6 is inclined outward. As the conveying wheel 4 enters the stacking guide rail 5 along with the lifting guide rail 6, the two conveying wheels 4 will move away from each other. Since the relative displacement distance of the two conveying wheels 4 relative to the sliding frame 3 is the same, it will not cause the overall center of the conveying frame 2 to shift, and the center of gravity can always remain stable. The cross-sections of the lifting guide rail 6, the stacking guide rail 5, and the ground rail 1 are all U-shaped, which allows the rolling wheel 10 to roll in them, and a lateral force can be applied to the rolling wheel 10 to make the sliding block 11 move relative to the sliding frame 3.

[0039] In use, when a 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, it will drive the corresponding wheel frame 9 and the sliding block 11 to move along the sliding groove 12, thereby driving the long rack 14 to move. Since the two long racks 14 mesh with the synchronous gear 13, the two long racks 14 move the same distance, thus achieving the purpose of the two sliding blocks 11 in the same sliding groove 12 moving the same distance.

[0040] Furthermore, by Figures 2-9 To make the device operate more stably, each sliding block 11 is provided with a first through groove 15, each long rack 14 is provided with a support groove 16 that runs through the front and back, the upper and lower sides of the synchronous gear 13 are provided with two support blocks 17 that are fixedly connected to the sliding groove 12, each support block 17 is slidably connected to the corresponding support groove 16, each sliding block 11 is fixedly connected to a push handle 18 on the side away from the corresponding long rack 14, and each sliding frame 3 is provided with a second through groove 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, which ensures that there is no interference between the long racks 14 and the sliding blocks 11 when the two sliding blocks 11 move towards each other; 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] When in use, when the two rollers 10 pass the lifting guide rail 6, they will move away from each other. At this time, each push handle 18 will extend from the corresponding second through slot 19, which makes it convenient for the staff to apply a moving force to the conveyor frame 2 by pushing the handle 18, making it convenient for the staff to operate.

[0043] Furthermore, by Figures 2-7To facilitate the retraction of each lifting guide rail 6, each sliding frame 3 is fixedly connected to an extension platform 20 on the side near the corresponding lifting guide rail 6. Each extension platform 20 is fixedly connected to a guide post 21 on its upper side. Each guide post 21 is fitted with a lifting sleeve 22 on its outer side. Each lifting sleeve 22 is fixedly connected to the corresponding lifting guide rail 6. Each guide post 21 is provided with a guide groove 23 on its outer side. Each lifting sleeve 22 is fixedly connected to a guide block 24 that matches the guide groove 23.

[0044] When in use, when it is necessary to retract the lifting guide rail 6 from the ground rail 1, an upward force can be applied to the lifting sleeve 22. The lifting sleeve 22 moves upward along the guide post 21. At this time, the guide block 24 slides upward along the guide groove 23, thereby disengaging the lifting guide rail 6 from the ground rail 1.

[0045] Furthermore, by Figure 7 As shown, the guide groove 23 includes a lifting part 25 and a rotating part 26. The upper end of the lifting part 25 is connected to the rotating part 26, and the horizontal rotation angle of the rotating part 26 is 90°.

[0046] In 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 will drive the lifting guide rail 6 to rotate 90° towards the side closer to the conveyor frame 2, and the lifting guide rail 6 will be retracted close to the front and rear sides of the conveyor frame 2.

[0047] Furthermore, by Figures 2-7 To ensure the lifting guide rail 6 is more stably fixed, each guide post 21 has a limiting hole 27 on its side. A first return spring 28 is fixedly connected inside each limiting hole 27, and a first limiting block 29 is fixedly connected to the outside of the first return spring 28. A limiting 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 that is slidably connected to the limiting groove 30 is provided on the side of each first limiting block 29 near the limiting 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] In use, when the lifting guide rail 6 and the ground rail 1 are in a coordinated state, the first limiting block 29 and the limiting through groove 30 cooperate to limit the lifting sleeve 22. When it is necessary to retract the lifting guide rail 6, the top block 31 can be pushed. The top block 31 pushes the first limiting block 29 to move along the limiting hole 27 toward the first reset spring 28, so that the first limiting block 29 is disengaged from the limiting through groove 30. At this time, under the action of the power spring 32, the lifting sleeve 22 is driven to move upward, and the lifting guide rail 6 is retracted.

[0049] Furthermore, by Figures 2-7 To fix and limit the upper conveyor frame 2, each sliding block 11 is fixedly connected to a first connecting plate 33 on the side near the corresponding synchronous gear 13, each first connecting plate 33 is fixedly connected to a second connecting plate 34 on the side near the corresponding lifting sleeve 22, each lifting sleeve 22 is fixedly connected to a second limiting block 35 on the side away from the corresponding lifting guide rail 6, each second connecting plate 34 is fixedly connected to a second mating block 36 that matches the second limiting block 35, and a stacking limiting plate 37 is fixedly connected to the upper side of the second connecting plate 34. Each of the front and rear sides of the conveyor frame 2 is provided with a manual crossbar 38, and the left and right sides of each manual crossbar 38 are rotatably connected to the corresponding lifting sleeve 22.

[0050] 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 limiting block 35 is close to the conveyor frame 2. As the two conveyor wheels 4 move away from each other, the second mating block 36 will gradually approach the corresponding second limiting block 35 to limit the reverse rotation of the second limiting block 35. At the same time, the stacking limiting plate 37 will move to the upper side of the stacking guide rail 5 with the second connecting plate 34 to limit the conveyor wheel 4 on the upper side of the stacking guide rail 5, which increases the stability of the device stacking. When it is necessary to unfold the lifting guide rail 6, first ensure that the conveyor wheel 4 is on the ground rail 1. At this time, the second mating block 36 is not mating with the second limiting block 35. Press down the manual crossbar 38 to drive the corresponding lifting sleeve 22 to move down until the first limiting block 29 and the limiting through groove 30 are mated, thus completing the unfolding of the lifting guide rail 6.

[0051] Furthermore, by Figures 8-11To facilitate operation, the conveyor frame 2 is equipped with two symmetrically arranged rotatable power shafts 39 inside. A square rod 40 is fixedly connected to both the front and rear sides of each power shaft 39. Each power shaft 39 also has a power abutment rod 41 threadedly connected to the conveyor frame 2 on both its front and rear sides. The front and rear sides of each power shaft 39 are slidably connected to the corresponding power abutment rod 41 via the square rod 40. A connecting shaft 42 is provided between two power shafts 39, and both sides of the connecting shaft 42 are fixed... A first bevel gear 43 is connected, and a second bevel gear 44 that meshes with the first bevel gear 43 is fixedly connected to the middle of each power shaft 39. A power gear 45 is fixedly connected to the middle of each power shaft 39, and a power rack 46 meshes with the upper side of each power gear 45. A pressing hole is provided on the conveyor frame 2 corresponding to the position of each power rack 46, so that the operator can press the power rack 46 through the pressing hole. A second return spring 47 is provided on the upper side of each power rack 46.

[0052] In use, when it is necessary to raise the lifting guide rail 6, any one of the power racks 46 can be pressed directly. 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 abutment 41 to rotate through the square rods 40 on its front and rear sides. Since the power abutment 41 is threadedly connected to the conveyor frame 2, the power abutment 41 will move towards the corresponding top block 31 while rotating. When the power abutment 41 presses the top block 31, each lifting guide rail 6 can be raised. At this time, the corresponding power rack 46 is released, and each power rack 46 is reset under the action of the corresponding second return spring 47.

[0053] Furthermore, by Figures 8-11 To facilitate the retraction of the support mechanism 8, the support frame 7 has two rotatably connected transverse shafts 48. The lower side of each support mechanism 8 is fixedly connected to the corresponding transverse shaft 48. A third bevel gear 49 is fixedly connected to both the left and right ends of each transverse shaft 48. A fourth bevel gear 50 meshes with the upper side of each third bevel gear 49. An adjusting rod 51 is fixedly connected to the upper side of each fourth bevel gear 50. An adjusting knob 52 is slidably fitted on the upper side of each adjusting rod 51. A tension spring 53 is provided inside each adjusting knob 52. Multiple limiting protrusions 54 are fixedly connected to the lower side of each adjusting knob 52. The upper side of the conveyor frame 2 has limiting grooves 55 that correspond one-to-one with the limiting protrusions 54.

[0054] When in use, if the support mechanism 8 needs to be retracted, the adjustment knob 52 can be pulled up. At this time, the limiting protrusion 54 and the limiting groove 55 are disengaged, and the adjustment knob 52 can be rotated. Rotating the adjustment knob 52 will drive the adjustment rod 51 to rotate, which in turn drives the third bevel gear 49 to rotate through the fourth bevel gear 50, causing the corresponding transverse rotating shaft 48 to rotate, thereby driving the support mechanism 8 to rotate and retract.

[0055] Furthermore, by Figures 8-11 To enable adjustment of the support position, the support mechanism 8 includes a rotating block 56 fixedly connected to the corresponding transverse 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. A fulcrum 59 is fixedly connected to the upper side of the support rod 58. Furthermore, a fixing pin and multiple fixing holes are provided between the large turntable 57 and the rotating block 56, which can adjust and fix the large turntable 57 relative to the rotating block 56 at multiple angles.

[0056] 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, which facilitates the support and transportation of materials of different types.

[0057] When using this invention, the material can first be supported by the support mechanism 8. During normal use, the conveyor frame 2 can be moved by the cooperation of the conveyor wheel 4 and the ground rail 1. Then, the material is 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 conveyor frame 2, it can clean the debris inside the ground rail 1 and increase the movement stability of the conveyor frame 2.

[0058] After material conveying is completed, multiple conveyor frames 2 can be stacked to reduce the floor space occupied by the multiple conveyor frames 2. For ease of explanation, when stacking is required, the two stacked conveyor frames 2 are simply defined as the upper conveyor frame 2 and the lower conveyor frame 2. When stacking, any one of the power racks 46 of the upper conveyor frame 2 can be pressed directly. 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 abutment 41 to rotate through the square rods 40 on its front and rear sides. Since the power abutment 41 is threadedly connected to the conveyor frame 2, the power abutment 41 will move towards the corresponding top block 31 while rotating. When the power abutment 41 presses the top block 31, the top block 31 pushes the first limiting block 29 along the limiting hole 27 toward the first reset spring 28, causing the first limiting block 29 to disengage from the limiting through groove 30. At this time, under the action of the power spring 32, the lifting sleeve 22 moves upward. 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 and retract close to the front and rear sides of the conveyor frame 2. The corresponding power rack 46 is released, and each power rack 46 is reset under the action of the corresponding second reset spring 47. Then, the four lifting guide rails 6 at the front and rear ends of the upper conveyor frame 2 are rotated and retracted, so that the conveying wheel 4 of the upper conveyor frame 2 can be pushed into the stacking guide rail 5 through the lifting guide rail 6 of the lower conveyor frame 2, thus completing the stacking of the two conveyor frames 2.

[0059] Then, the lifting guide rail 6 of the lower conveyor 2 is also retracted in the same way, so that it can be stacked again as the upper conveyor 2. After stacking, the stacking limiting plate 37 will move to the upper side of the stacking guide rail 5 along 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 device stacking.

[0060] This invention features a novel structure, ingenious design, and simple and convenient operation. Through this design, it effectively facilitates the stacking of the conveyor frame 2, making the center of gravity more stable during device transportation, and enables the easy folding of each lifting guide rail 6. It also adds the function of cleaning debris inside the ground rail 1, facilitating operation by staff and allowing for adjustment of the support position.

[0061] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
