Description

Technical Field

[0001] The utility model belongs to the technical field of tire production, and particularly relates to an inner liner transport trolley with a self-locking device. Background Art

[0002] During the manufacturing process of tires, the inner liner needs to be transported to the molding workshop after being processed by the production equipment for subsequent tire molding work and for use in the winding of the inner liner on the production equipment. The inner liner transport trolley with a self-locking device must always remain in a self-locking state when the trolley is not in use on the equipment, after winding and feeding materials, or when stored in a vertical warehouse, or when transported by an AGV trolley, to prevent the trolley's shaft from rotating, causing the inner liner to fall to the ground and get dirty, or affecting the work of the stacker when entering and exiting the vertical warehouse, or exposing the material during transportation and causing deformation, or the material being rolled under the vehicle and affecting production work. Utility Model Content

[0003] The purpose of the utility model is to solve the deficiencies of the above-mentioned technology and to provide a liner transport trolley with a self-locking device.

[0004] To this end, the utility model provides a liner transport trolley with a self-locking device, comprising a bottom plate, brackets are fixed on both sides of the bottom plate, a material I-shaped wheel and a pad cloth I-shaped wheel are rotatably matched between the brackets, one end of the rotating shaft of the material I-shaped wheel is fixedly connected to a first locking gear, one end of the rotating shaft of the pad cloth I-shaped wheel is fixedly connected to a second locking gear, and the first locking gear and the second locking gear are located on the bracket on the same side;

[0005] A first locking beam is also provided on the bracket, and the first locking beam is rotatably matched with the bracket through a rotating shaft. One end of the first locking beam is fixedly connected to a first locking block, and the first locking block can engage with the first locking gear; a second locking beam is fixedly connected to the first locking beam, and the end of the second locking beam is fixedly connected to a second locking block, and the second locking block can engage with the second locking gear; a spring fixing rod is also fixedly connected to the bracket, and the spring fixing rod is connected to the first locking beam through a spring.

[0006] Furthermore, a connecting rod is hinged to the other end of the first locking beam, and a pulling rod is hinged to the other end of the connecting rod.

[0007] Furthermore, a plurality of mounting plates are fixed on the bracket, and a material guide roller is arranged between two symmetrically arranged mounting plates.

[0008] Furthermore, rollers are provided at the bottom of the base plate for moving the trolley.

[0009] The utility model provides a liner transport trolley with a self-locking device, which has the following beneficial effects:

[0010] The utility model realizes self-locking by means of a connecting rod type linkage combined with gear meshing, and can realize the simultaneous self-locking and stopping rotation of the material spool and the padding cloth spool. When loading and unloading materials, the front end of the locking beam can be lifted through a lifting mechanism to cancel the meshing between the locking block and the locking gear, and the equipment is released from the self-locking state. Or when manual processing is required, the self-locking state can also be cancelled by lifting the handle to cancel the meshing between the locking block and the locking gear. When the equipment is transported, only the force applied to the self-locking device needs to be removed, and self-locking can be realized through the action of the spring. The self-locking device is reliable, has a relatively light overall weight, has good durability and is not easily damaged, and is fixed to the trolley for use and handling. During use or handling, it can prevent the roller from rotating automatically, prevent the material from falling off, reduce the safety risks of equipment operation, facilitate transportation, and prevent the material from deforming and being contaminated due to the automatic rotation of the roller.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following further illustrates the utility model in conjunction with the drawings and specific embodiments to help understand the content of the utility model. The methods used in the utility model are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercially available products unless otherwise specified.

[0018] As Figure 1As shown in the figure, the utility model provides an inner liner transportation trolley with a self-locking device, which includes a bottom plate 4. On both sides of the bottom plate 4, brackets 14 are symmetrically fixed. On the brackets 14, a plurality of mounting plates 2 are symmetrically fixed. Between two symmetrically arranged mounting plates 2, a material guiding roller 1 is arranged. Between the brackets 14, a material I-beam wheel 10 and a backing cloth I-beam wheel 11 are rotatably matched through bearing seats. During use, the inner liner material with backing cloth wound on the material I-beam wheel 10 passes through the material guiding roller 1, and the backing cloth is separated for feeding. The separated backing cloth is rewound onto the backing cloth I-beam wheel 11.

[0019] As Figure 2 shown in the figure, one end of the rotating shaft of the material I-beam wheel 10 is fixedly connected with a first locking gear 3, and one end of the rotating shaft of the backing cloth I-beam wheel 11 is fixedly connected with a second locking gear 9. The first locking gear 3 and the second locking gear 9 are located on the same side of the bracket 14. At the bottom of the bottom plate 4, rollers 5 are also arranged to facilitate the movement of the trolley.

[0020] As Figures 3-5 shown in the figure, a first locking beam 7 is also arranged on the bracket 14. The first locking beam 7 is rotatably matched with the bracket 14 through a rotating shaft 6. One end of the first locking beam 7 is fixedly connected with a first locking block 18. The first locking block 18 can be engaged with the first locking gear 3 to limit the rotation of the first locking gear 3. A second locking beam 17 is fixedly connected to the first locking beam 7. The end of the second locking beam 17 is fixedly connected with a second locking block 13. The second locking block 13 can be engaged with the second locking gear 9 to limit the second locking gear 9. A spring fixing rod 15 is also fixedly connected to the bracket 14. The spring fixing rod 15 is connected with the first locking beam 7 through a spring 16. The elastic force of the spring 16 is used to provide the pulling force for the continuous engagement of the first locking beam 7 and the second locking gear 9. In the natural state, the elastic force of the spring 16 pulls the first locking beam 7 to rotate counterclockwise around the rotating shaft 6, so that the first locking block 18 and the second locking block 13 are respectively engaged with the first locking gear 3 and the second locking gear 9.

[0021] The other end of the first locking beam 7 is hinged with a connecting rod 12, and the other end of the connecting rod 12 is hinged with a pull rod 8. During use, when the pull rod 8 is rotated clockwise, the connecting rod 12 drives the first locking beam 7 to rotate clockwise around the rotating shaft 6, so that the first locking block 18 and the second locking block 13 are respectively disengaged from the first locking gear 3 and the second locking gear 9, and the material I-beam wheel 10 and the backing cloth I-beam wheel 11 can rotate freely.

[0022] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "left", "right", "upper", "lower", "top", "bottom", "front", "rear", "inner", "outer", "back", "middle", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0023] However, the above are only specific embodiments of the present utility model, and the scope of implementation of the present utility model cannot be limited thereby. Therefore, the replacement of equivalent components or equivalent changes and modifications made according to the scope of patent protection of the present utility model should still fall within the scope covered by the claims of the present utility model.
