[0001] The utility model belongs to the technical field of tire stacking, and particularly relates to a waste tire stacking device. Background Art

[0002] A Chinese patent document with the publication number of CN216186809U discloses a tire inner tube storage and stacking tooling, which includes a base. Support legs are welded on the base. The upper ends of the support legs are in contact with a folding side wall. A connecting plate is welded on the folding side wall, and the connecting plate is in contact with the support legs. A connecting shaft is fixedly connected inside the base. The outer part of the connecting shaft is rotationally sleeved with a connecting plate. A nut is welded on the connecting shaft, and a tray is placed on the base. By designing components such as a tray, a folding side wall, a connecting shaft, a connecting plate, a flat washer, and a nut on the basis of the base, a foldable storage rack is formed.

[0003] Although the above comparative document can be folded to reduce space occupation, when stacking tires, it lacks a central limiting structure. When the tires are stacked too high, the tires may slide off due to unstable center of gravity. And the weight of large tires is very high, and the sliding-off tires are likely to pose a great safety hazard to the staff below them. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a waste tire stacking device to solve the technical problem in the above background art that there is no central limiting structure, and the tires stacked at a high position are likely to slide off, resulting in a great safety hazard.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions:

[0006] A waste tire stacking device includes: a base, a turntable, and a vertical pipe. The base is a fixed platform. A countersunk hole is provided at each of the four corners of the base to form a locking hole. A circular embedded position is provided at the center of the base. A turntable with a disc structure is embedded in the embedded position. A rod-shaped vertical pipe is vertically provided at the center of the turntable. A columnar positioning column is provided at the center of the bottom of the turntable. A cylindrical cavity for accommodating the positioning column is provided at the center of the bottom of the embedded position of the base to form a positioning cavity. The turntable is centered by embedding the positioning column in the positioning cavity.

[0007] Further: In order to facilitate the user to find the marks on the tire, the base and the turntable are rotatably connected. A support ring with a ring structure is provided at the bottom of the turntable. Multiple groups of movable balls are circumferentially arranged at the bottom of the support ring. The movable balls are movably embedded in the support ring. A track for the movable balls to roll circumferentially is provided on the base to form a ball groove.

[0008] Further: To facilitate the forklift to uniformly transfer all the tires on the pallet, two sets of fork slots are provided on the pallet to facilitate the insertion of the fork teeth of the forklift.

[0009] Further: To facilitate the separation of the pallet and the vertical pipe, the pallet and the vertical pipe are detachably connected through a connecting seat. The bottom of the vertical pipe is connected and fixed to a connecting seat with a plate-shaped structure as the main body. A T-shaped block with an inverted T-shaped longitudinal section is provided at the bottom of the connecting seat. An embedded groove for the T-shaped block to slide is provided in the pallet, and the outer contour of the longitudinal section of the embedded groove is the same as the outer contour of the longitudinal section of the T-shaped block.

[0010] Further: To facilitate adding traction when separating the pallet and the vertical pipe, at least one set of rope-passing holes are provided on the pallet to form pulling holes.

[0011] Further: To facilitate the crane to uniformly transfer all the tires on the pallet, the top of the vertical pipe is closed and connected with a hook.

[0012] Further: To prevent the overall tilting of the tires when the tires are stacked too high, the bottom of the pallet is locked and fixed to the base by a locking mechanism. The locking mechanism includes: a rotating block, a rotating handle, locking teeth, a locking hole, an elliptical inner hole, a movable column, a spring, and an inserting column. The positioning column is a hollow shell structure. A circular hole is provided at the bottom of the positioning column to form a locking hole. A columnar inserting column is fixed at the center of the positioning cavity. The diameter of the inserting column is less than or equal to the diameter of the locking hole. A set of vertically through holes with a rectangular cross-section are provided in the inserting column. Two movable columns with a square rod structure slide in the through holes. At least one spring with an elongation tendency is used to connect between the two movable columns. Tooth-shaped structures protruding outward are provided at the top of the two movable columns in the direction away from each other to form locking teeth. An opening for the locking teeth to slide along with the movable column is provided at the top of the inserting column. A rotating block is rotatably fitted below the positioning cavity. An inner cavity with an elliptical cross-section is provided in the rotating block to form an elliptical inner hole. The two movable columns are tangent to the inner wall of the elliptical inner hole. When the spring is in the longest elongation state, the movable column is tangent to the near major axis end of the elliptical inner hole (the near major axis end is the position near the major axis of the elliptical inner hole).

[0013] Further: To facilitate the rotation of the rotating block, a horizontal rod-shaped structure is fixed on the outer circumferential wall of the rotating block to form a rotating handle.

[0014] In summary, the present utility model has the following beneficial effects:

[0015] ① It can prevent the stacked tires from slipping and detaching from a high place: By setting up the vertical pipe, the waste tires are stacked on the pallet in the way of penetrating the vertical pipe, and the vertical pipe provides horizontal limit to prevent the tires from slipping, shifting and falling off.

[0016] ②It is convenient to query the marks on the tire: By setting up the ball groove and movable balls, when it is necessary to query the marks on the tire to identify the type of tire, and the mark on the tire is on the side where the staff is not located, the turntable can be rotated. The turntable relies on the movable balls at its bottom to roll in the ball groove to complete its circumferential rotation, thus facilitating the staff to find the marks on the tire to identify the type of tire.

[0017] ③It can be uniformly transferred by a forklift: By setting up the fork groove, when it is necessary to uniformly transfer all the tires on the turntable by a forklift, first turn the handle, and the handle drives the rotating block to rotate. When the near short diameter end of the elliptical inner hole in the rotating block is tangent to the two groups of movable columns, at this time, the two groups of movable columns are compressed and close together by the elliptical inner hole. At this time, the locking teeth retract into the insertion column, and at this time, the insertion column can be pulled out from the locking hole, and the locking mechanism releases the limit connection between the base and the turntable. At this time, the forklift inserts its fork teeth into the fork groove, and then lifts the fork teeth to separate the turntable from the base. At this time, all the tires on the turntable can be uniformly transferred by the forklift.

[0018] ④It can be uniformly transferred by a crane: By setting up the hook, when it is necessary to uniformly transfer all the tires on the turntable by a crane, first turn the handle, and the handle drives the rotating block to rotate. When the near short diameter end of the elliptical inner hole in the rotating block is tangent to the two groups of movable columns, at this time, the two groups of movable columns are compressed and close together by the elliptical inner hole. At this time, the locking teeth retract into the insertion column, and at this time, the insertion column can be pulled out from the locking hole, and the locking mechanism releases the limit connection between the base and the turntable. At this time, the lifting ring of the crane is connected to the hook at the top of the vertical pipe, and then the lifting ring of the crane is lifted to separate the turntable from the base. At this time, all the tires on the turntable can be uniformly transferred by the crane. Description of the Drawings

Specific embodiments

[0031] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0032] Embodiment:

[0033] Please refer to Figures 1 - 11 , the present utility model provides the following technical solution:

[0034] A waste tire stacking device includes: a base 1, a support platform 2, and a vertical pipe 3; the base 1 is a fixed platform, and each of the four corners of the base 1 is provided with a countersunk hole to form a locking hole 4. The center of the base 1 is provided with a circular embedded position, and a disc-shaped support platform 2 is embedded in the embedded position. A rod-shaped vertical pipe 3 is vertically provided at the center of the support platform 2. A columnar positioning post 7 is provided at the center of the bottom of the support platform 2. A cylindrical cavity for accommodating the positioning post 7 is formed at the center of the bottom of the embedded position of the base 1 to form a positioning cavity 8. The support platform 2 is centered by being embedded in the positioning cavity 8 by relying on the positioning post 7.

[0035] The base 1 and the support platform 2 are rotatably connected. A ring-shaped support ring 24 is provided at the bottom of the support platform 2. A plurality of groups of movable balls 25 are circumferentially arranged at the bottom of the support ring 24. The movable balls 25 are movably embedded in the support ring 24, and a track for the circumferential rolling of the movable balls 25 is provided on the base 1 to form a ball groove 11.

[0036] Two fork grooves 23 for the insertion of the fork teeth of a forklift are provided on the support platform 2.

[0037] The supporting platform 2 and the vertical pipe 3 are detachably connected through a connecting seat 5. The bottom of the vertical pipe 3 is connected and fixed to a connecting seat 5 whose main body is a plate-like structure. A T-shaped block 51 with an inverted T-shaped longitudinal section is provided at the bottom of the connecting seat 5. An embedded groove 21 for the T-shaped block 51 to slide is provided in the supporting platform 2. The outer contour of the longitudinal section of the embedded groove 21 is the same as the outer contour of the longitudinal section of the T-shaped block 51.

[0038] At least one set of rope-passing holes are provided on the supporting platform 2 to form pulling holes 22.

[0039] The top of the vertical pipe 3 is closed and is connected with a lifting hook 6.

[0040] The bottom of the supporting platform 2 is locked and fixed to the base 1 by a locking mechanism 9. The locking mechanism 9 includes: a rotating block 91, a rotating handle 92, locking teeth 93, a locking hole 94, an elliptical inner hole 95, a movable column 96, a spring 97, and an inserting column 98. The positioning column 7 is a hollow shell structure. A circular hole is provided at the bottom of the positioning column 7 to form the locking hole 94. A columnar inserting column 98 is fixed at the center of the positioning cavity 8. The diameter of the inserting column 98 is less than or equal to the diameter of the locking hole 94. A group of vertical through holes with a rectangular cross-section are provided in the inserting column 98. Two movable columns 96 with a square rod structure slide in the through holes. At least one spring 97 with an elongation tendency is used to connect the two movable columns 96. Tooth-like structures protruding outward are provided at the tops of the two movable columns 96 in the direction away from each other to form the locking teeth 93. An opening for the locking teeth 93 to slide along with the movable column 96 is provided at the top of the inserting column 98. A rotating block 91 is rotatably fitted below the positioning cavity 8. An inner cavity with an elliptical cross-section is provided in the rotating block 91 to form the elliptical inner hole 95. The two movable columns 96 are tangent to the inner wall of the elliptical inner hole 95. When the spring 97 is in the longest elongation state, the movable column 96 is tangent to the near major axis end of the elliptical inner hole 95 (the near major axis end is the position near the major axis of the elliptical inner hole 95).

[0041] A horizontal rod-like structure is fixed to the outer circumferential wall of the rotating block 91 to form the rotating handle 92.

[0042] Brief description of the usage process:

[0043] During use, the base 1 is fixedly connected to the ground by screwing a bolt into the locking hole 4. Again, as Figure 9 shown, the waste tires are stacked on the supporting platform 2 in turn in a way that the vertical pipe 3 penetrates through them. The vertical pipe 3 provides horizontal limit to prevent the tires from slipping, shifting, and falling off. When it is necessary to check the marks on the tires to identify the types of the tires, and the marks on the tires are not on the side of the staff, the supporting platform 2 can be rotated. The supporting platform 2 rolls in the ball groove 11 by means of the movable balls 25 at its bottom to complete its circumferential rotation, thereby facilitating the staff to find the marks on the tires to identify the types of the tires.

[0044] When it is necessary to use a forklift to uniformly transfer all the tires on the pallet 2, first turn the turning handle 92. The turning handle 92 drives the rotating block 91 to rotate. When the near short-diameter end of the elliptical inner hole 95 in the rotating block 91 (the near short-diameter end is the position near the short diameter of the elliptical inner hole 95) is tangent to the two groups of movable columns 96, at this time, the two groups of movable columns 96 are compressed and close to each other by the elliptical inner hole 95. At this time, the locking tooth 93 retracts into the inserting column 98, and at this time, the inserting column 98 can be pulled out from the locking hole 94. The locking mechanism 9 releases the limiting connection between the base 1 and the pallet 2. At this time, the forklift inserts its inserting teeth into the fork groove 23, and then lifts the inserting teeth to separate the pallet 2 from the base 1. At this time, all the tires on the pallet 2 can be uniformly transferred by the forklift.

[0045] When it is necessary to use a crane to uniformly transfer all the tires on the pallet 2, first turn the turning handle 92. The turning handle 92 drives the rotating block 91 to rotate. When the near short-diameter end of the elliptical inner hole 95 in the rotating block 91 is tangent to the two groups of movable columns 96, at this time, the two groups of movable columns 96 are compressed and close to each other by the elliptical inner hole 95. At this time, the locking tooth 93 retracts into the inserting column 98, and at this time, the inserting column 98 can be pulled out from the locking hole 94. The locking mechanism 9 releases the limiting connection between the base 1 and the pallet 2. At this time, the lifting ring of the crane is connected to the hook 6 at the top of the vertical pipe 3, and then the lifting ring of the crane is lifted to separate the pallet 2 from the base 1. At this time, all the tires on the pallet 2 can be uniformly transferred by the crane.

[0046] When it is necessary to uniformly unload all the tires on the pallet 2, slide the connecting seat 5 out of the embedded groove 21, and then the vertical pipe 3 and the connecting seat 5 as a whole are separated from the pallet 2. Pull out the vertical pipe 3 or pull out the pallet 2, and all the tires on the pallet 2 can be separated or unloaded.

[0047] When assembling the base 1 and the pallet 2, first, place the pallet 2 in the embedded position of the base 1, insert the positioning column 7 into the positioning cavity 8 to complete the center positioning, and then turn the turning handle 92. The turning handle 92 drives the rotating block 91 to rotate. When the near short-diameter end of the elliptical inner hole 95 in the rotating block 91 rotates to be tangent to the two groups of movable columns 96, at this time, the two groups of movable columns 96 are compressed and close to each other by the elliptical inner hole 95. At this time, the locking tooth 93 retracts into the inserting column 98, and at this time, the inserting column 98 can be inserted into the locking hole 94. After the inserting column 98 is inserted into the locking hole 94, release the turning handle 92. Under the action of the spring 97, the two groups of movable columns 96 move away from each other. At this time, the two groups of movable columns 96 are tangent to the near long-diameter end of the elliptical inner hole 95. At this time, the locking teeth 93 at the tops of the two groups of movable columns 96 protrude from the inserting column 98 following the movement of the movable columns 96. At this time, the protruding locking teeth 93 make the inserting column 98 unable to be pulled out from the locking hole 94. Furthermore, the locking mechanism 9 completes the locking connection between the base 1 and the pallet 2 (this locking connection is only a locking limit in the vertical direction and does not limit the rotational cooperation between the base 1 and the pallet 2). At this time, the pallet 2 rolls and cooperates in the ball groove 11 by means of the movable balls 25 at its bottom.

[0048] This specific embodiment is only an interpretation of the present utility model and does not limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
