DETAILED DESCRIPTION

[0033] 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.

[0034] Embodiment 1 In some complex working environments, stackers are often moved by tracks. The tracks are flat and fixed to the ground, and the stacker needs to remain flat with the tracks. The stacking height of the stacker will be affected by the height of the ground, and it is impossible to unload on higher terrain, so the stacking height is still limited.

[0035] See also Figures 1 to 4 and Figures 7 to 13 The present invention provides the following technical solutions: a circulating stepping stacker, comprising a door frame 1, a rotating device 2, a pitching device 3, a discharge belt 4, a walking device 5, a track 6 and a feeding belt 9, the track 6 comprising two guide rails 61, and further comprising: The limiting mechanism 7 is arranged on the track 6. The limiting mechanism 7 includes a plurality of groups of limiting components 71. Each group of limiting components 71 is arranged along the length direction of the track 6. A group of limiting components 71 is arranged on both the inner and outer sides of each guide rail 61. Each group of limiting components 71 includes a plurality of equally spaced limiting members 72 fixedly connected to the corresponding guide rail 61. Each limiting member 72 is arranged obliquely. The limiting members 72 on both the inner and outer sides of the same guide rail 61 correspond to each other one by one and are symmetrical to each other. The climbing mechanism 8 is provided with two groups, and is symmetrically arranged at the bottom of the door frame 1. The two groups of climbing mechanisms 8 correspond to the positions of the two guide rails 61 one by one. The climbing mechanism 8 includes a hydraulic cylinder 81. The two ends of the hydraulic cylinder 81 are respectively provided with a first movable part 82 and a second movable part 83. The bottom of the first movable part 82 and the second movable part 83 away from the hydraulic cylinder 81 are respectively provided with a first groove 84 and a second groove 85 adapted to the limit member 72. The first groove 84 and the second groove 85 can be intermittently matched with the limit member 72 through the extension and retraction of the hydraulic cylinder 81.

[0036] A set of limit assemblies 71 is respectively arranged on the inner and outer sides of each guide rail 61. The limit members 72 of the two sets of limit assemblies 71 on the same guide rail 61 correspond to each other in position and have the same inclination angle. The purpose of setting two sets of limit assemblies 71 for each guide rail 61 is to increase the limit force through two symmetrical limit members 72.

[0037] The inclination angle of each limiting member 72 is consistent, so as to facilitate the use with the first card slot 84, the second card slot 85 and the third card slot 58, and ensure that each limiting member 72 can be connected with the first card slot 84, the second card slot 85 and the third card slot 58.

[0038] like Fig.12 As shown, when the first slot 84 and the second slot 85 are engaged with the corresponding limiting member 72, the limiting member 72 can limit the first movable member 82 and the second movable member 83 to prevent the first movable member 82 and the second movable member 83 from moving backward when climbing a slope.

[0039] like Figure 1 and Fig.13 As shown, the rotating device 2 includes a motor and a rotating shaft, which can drive the rotating shaft to rotate through the motor, and can adjust the angle of the discharge belt 4 on the rotating shaft, which is used for stacking materials at different positions of the stacker. The pitching device 3 includes a hydraulic telescopic rod, which can adjust the pitching height of the discharge belt 4, which is used to adjust the stacking height of the stacker. The walking device 5 is used to drive the stacker to move on the track 6, the feeding belt 9 is used for conveying the feed, and the discharge belt 4 is used for conveying the unloading. The rotating device 2, the pitching device 3, the discharge belt 4, the feeding belt 9 and the walking device 5 are all existing technologies and will not be repeated here.

[0040] like Figure 7 and Figure 8 As shown, the outer wall of the hydraulic cylinder 81 is fixedly connected with a guide member 86, and the guide member 86 is arranged at the bottom of the door base frame 1. A guide groove 87 is opened at the bottom of the guide member 86, and a first roller 88 adapted to the corresponding guide rail 61 is rotatably connected inside the guide groove 87.

[0041] like Figures 7 to 9As shown, a first avoidance groove 89 is provided inside the first movable member 82, and a first rotating shaft 810 is fixedly connected inside one side of the first avoidance groove 89. The first movable member 82 is rotatably connected to one end of the hydraulic cylinder 81 through the first rotating shaft 810, and a second roller 811 adapted to the corresponding guide rail 61 is rotatably connected inside the side of the first avoidance groove 89 away from the hydraulic cylinder 81. Under normal conditions, that is, when the stocker is not moving, the end of the first movable member 82 away from the hydraulic cylinder 81 can make the second roller 811 contact the corresponding guide rail 61 under the action of its own gravity, and the second roller 811 can move on the corresponding guide rail 61.

[0042] The climbing mechanism 8 also includes a first mounting member 812 fixedly connected to the bottom of the door seat frame 1, a mounting groove 813 is provided at the bottom of the first mounting member 812, a second rotating shaft 814 is fixedly connected inside the mounting groove 813, one end of the hydraulic cylinder 81 away from the first movable member 82 is rotatably connected to the first mounting member 812 through the second rotating shaft 814, one end of the second movable member 83 is located inside the mounting groove 813 and is rotatably connected to the outer wall of the second rotating shaft 814, a second avoidance groove 815 is provided inside the second movable member 83, and a third roller 816 adapted to the corresponding guide rail 61 is rotatably connected inside the side of the second avoidance groove 815 away from the first mounting member 812.

[0043] Under normal conditions, that is, when the stocker is not moving, the end of the second movable member 83 away from the hydraulic cylinder 81 can make the third roller 816 contact the corresponding guide rail 61 under the action of its own gravity, and the third roller 816 can move on the corresponding guide rail 61.

[0044] When the walking device 5 drives the door seat frame 1 to move forward, it can drive the first movable member 82 and the second movable member 83 to move between the limiting member 72. Every time the end of the first movable member 82 and the second movable member 83 away from the hydraulic cylinder 81 contacts the limiting member 72, it can squeeze the end away from the hydraulic cylinder 81 to tilt up, so that the third roller 816 and the second roller 811 can be away from the guide rail 61. Subsequently, when the end of the first movable member 82 and the second movable member 83 away from the hydraulic cylinder 81 no longer contacts the limiting member 72, the end of the first movable member 82 and the second movable member 83 away from the hydraulic cylinder 81 can make the third roller 816 and the second roller 811 contact the guide rail 61 again under the action of gravity, so that the first clamping groove 84 and the second clamping groove 85 can be clamped with the limiting member 72 at the corresponding position. Through the rotation setting of the first movable member 82 and the second movable member 83, the first movable member 82 and the second movable member 83 can cooperate with the limiting members 72 at different heights to limit.

[0045] like Figure 4As shown, the walking device 5 includes a front wheel 51 and a rear wheel 52, the first movable member 82 is located at one end of the hydraulic cylinder 81 close to the rear wheel 52, and the second movable member 83 is located at one end of the hydraulic cylinder 81 close to the front wheel 51. When the walking device 5 drives the door frame 1 to move, each of the first roller 88, the second roller 811 and the third roller 816 can move on the corresponding guide rail 61.

[0046] like Fig.12 As shown, when the first slot 84 and the second slot 85 of the first movable member 82 and the second movable member 83 are both engaged with the corresponding limit member 72, the extension of the hydraulic cylinder 81 can move the second movable member 83 toward the direction close to the front wheel 51, so that the second slot 85 moves to the position of the next limit member 72 and engages with it. When the hydraulic cylinder 81 in the extended state contracts, the first movable member 82 can move toward the direction close to the front wheel 51, so that the first slot 84 moves to the position of the next limit member 72 and engages with it.

[0047] In actual use, the track 6 can be laid on a higher terrain. At this time, the track 6 has a certain slope. When climbing is required, the climbing mechanism 8 is first installed to the bottom of the door frame 1, so that the first slots 84 and the second slots 85 of the first movable member 82 and the second movable member 83 are engaged with the corresponding limit members 72. At this time, the hydraulic cylinder 81 is extended, and the first movable member 82 and the corresponding limit member 72 are limited, which can make the second movable member 83 move toward the direction close to the front wheel 51. During the movement of the second movable member 83, the end of the second movable member 83 away from the hydraulic cylinder 81 will preferentially contact the next limit member 72 and be squeezed and tilted, and then break away from the contact with the limit member 72, and can be reset under the action of gravity, so that the third roller 816 contacts the guide rail 61 again, and the second slot 85 is engaged and limited with the limit member 72 at this position, and then the second movable member 81 is in the extended state. The hydraulic cylinder 81 is retracted, and under the limiting action of the second movable member 83, the first movable member 82 is subjected to the pulling force of the hydraulic cylinder 81, so that the first movable member 82 moves in the direction close to the front wheel 51. During the movement of the first movable member 82, the end of the first movable member 82 away from the hydraulic cylinder 81 will preferentially contact the next limiting member 72 and be squeezed and tilted, and then break away from the contact with the limiting member 72. Under the action of gravity, the second roller 811 can contact the guide rail 61 again, so that the first clamping groove 84 is engaged and limited with the limiting member 72 at this position, and then the hydraulic cylinder 81 is extended and contracted, and the positions of the first movable member 82 and the second movable member 83 are gradually adjusted. The stacker is moved in this cycle, which can enable the stacker to move on tracks 6 with different slopes. Therefore, by adjusting the position height of the stacker, the stacking height of the stacker can be increased.

[0048] To sum up, the present invention can lay the track 6 on a higher terrain through the setting of the climbing mechanism 8. When climbing is required, the climbing mechanism 8 is first installed to the bottom of the door frame 1, so that the first slot 84 and the second slot 85 of the first movable member 82 and the second movable member 83 are engaged with the corresponding limit member 72. At this time, the extension of the hydraulic cylinder 81 can make the second movable member 83 move toward the direction close to the front wheel 51, so that the second slot 85 is engaged with the next limit member 72, and then the hydraulic cylinder 81 in the extended state is contracted, so that the first slot 84 is engaged with the next limit member 72. Such a cycle can enable the stacker to move on tracks 6 with different slopes, and the stacking height of the stacker can be increased by adjusting the height of the stacker, thereby improving the practicability of the stacker.

[0049] Embodiment 2 On the basis of the above-mentioned embodiment, when the climbing mechanism of the stacker fails during the climbing process, the climbing mechanism needs to be disassembled and repaired. The stacker will slide down the slope if the climbing mechanism loses the limit, which poses an installation hazard.

[0050] like Figures 4 to 6 As shown, the outer side of each rear wheel 52 is fixedly connected to a second mounting member 53 which is arranged obliquely, and the outer side of each second mounting member 53 is fixedly connected to two symmetrically arranged fixing members 54, and the interior of each second mounting member 53 is provided with a receiving groove 55, and the interior of each receiving groove 55 is provided with a third movable member 56, and the two third movable members 56 correspond one-to-one to the two guide rails 61.

[0051] One end of each third movable member 56 is rotatably connected to the bottom inner sides of the corresponding two fixing members 54 via a third rotating shaft 57 , and the other end bottom of each third movable member 56 is provided with a third slot 58 adapted to the limiting member 72 .

[0052] A third avoidance groove 59 is provided inside the third movable part 56, and a fourth roller 510 adapted to the corresponding guide rail 61 is rotatably connected inside the third avoidance groove 59 near the third rotating shaft 57. When the walking device 5 drives the door base frame 1 to move, each fourth roller 510 can move on the corresponding guide rail 61.

[0053] When the third engaging groove 58 of the third movable member 56 engages with the corresponding limiting member 72 , the walking device 5 drives the door frame 1 to move forward, so that the third engaging groove 58 can move to the position of the next limiting member 72 and engage with it.

[0054] Under normal conditions, that is, when the stacker is not moving, the end of the third movable member 56 away from the fixed member 54 can make the fourth roller 510 contact with the corresponding guide rail 61 under the action of its own gravity, and the fourth roller 510 can move on the corresponding guide rail 61. Through the rotation setting of the third movable member 56, the third movable member 56 can cooperate with the limiting members 72 at different heights to limit the position.

[0055] When the walking device 5 drives the door frame 1 to move forward, each time the end of the third movable member 56 away from the fixed member 54 contacts the limit member 72, the end away from the fixed member 54 can be squeezed and tilted, so that the fourth roller 510 can be away from the guide rail 61. Subsequently, when the end of the third movable member 56 away from the fixed member 54 no longer contacts the limit member 72, the end of the third movable member 56 away from the fixed member 54 contacts the guide rail 61 again under the action of gravity, so that the third clamping groove 58 can be clamped and limited with the limit member 72 at this position. Therefore, during the climbing process, the third movable member 56 is clamped with the limit member 72, so that the stacker can be limited in real time, thereby avoiding the stacker from sliding down the slope when the climbing mechanism 8 is disassembled, thereby improving the safety performance.

[0056] When the climbing mechanism 8 has no faults, the climbing mechanism 8 can also be disassembled, limited by the second movable member 83, and the disassembled climbing mechanism 8 can be installed on other stockers to improve versatility.

[0057] To summarize, through the arrangement of the third movable part 56, the present invention can make the end of the third movable part 56 away from the fixed part 54 squeeze and tilt when the end is in contact with the limiting part 72 when the stacker moves on the track 6. Then, when the end of the third movable part 56 away from the fixed part 54 is no longer in contact with the limiting part 72, the end of the third movable part 56 away from the fixed part 54 contacts the guide rail 61 again under the action of gravity, so that the third slot 58 can be engaged and limited with the limiting part 72 at this position. Therefore, during the climbing process, the stacker can be limited in real time by engaging the third movable part 56 with the limiting part 72, so as to avoid the stacker sliding down the slope when the climbing mechanism 8 is disassembled, thereby improving the safety performance.

[0058] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
