Description

Technical Field

[0001] The utility model belongs to the field of rubber tire industrial automation and relates to a transport trolley for tire vulcanization which can be lifted and lowered and then shifted. Background Art

[0002] In the rubber tire vulcanization industry, tire vulcanization transport trolleys (hereinafter referred to as vulcanization trolleys) play a vital role. Currently, there are obvious limitations in the shifting operation of rubber tire vulcanization transport trolleys.

[0003] Typically, the vulcanizing trolley must be moved with the aid of a forklift or a ground auger. This is primarily because the trolley's fixed wheels are in contact with the ground, and according to existing technology, it can only be moved by lifting the entire trolley. This method has a serious disadvantage: it requires a large amount of space. In actual production, if the space required is insufficient, the trolley cannot be moved. Furthermore, during the rubber tire vulcanization process, the vulcanizer requires frequent mold changes, necessitating the relocation of the trolley. This limited space creates significant inconvenience for production.

[0004] Furthermore, this method of using a forklift or a trolley is inefficient. With multiple curing presses operating simultaneously, this inefficient method of movement cannot meet production demands. Forklifts and trolleys require time to prepare and execute, and their frequent use consumes significant time and manpower, reducing the efficiency of the entire production process.

[0005] In summary, the current method of transporting trolleys for rubber tire vulcanization has serious deficiencies in terms of site space and operational efficiency. This not only affects the smooth progress of production, but also limits the production capacity and benefits of enterprises. Utility Model Content

[0031] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0033] In the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings, or with reference to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention. Example

[0034] See also Figure 1-Figure 2 As shown, a tire vulcanization transport trolley includes a trolley body 1. The trolley body 1 is a rectangular frame structure that can conveniently carry and transport various items related to tire vulcanization. A directional wheel assembly 3 is provided below the trolley body 1 and is compatible with a track 2. During normal transport, the directional wheel assembly 3 and the track 2 form a wheel-rail fit, providing stable guidance and support for the trolley, ensuring smooth travel along the designated track.

[0035] The four corners of the trolley body 1 are provided with lifting universal caster devices 4, which are composed of a floor brake lifting assembly 41 and a universal wheel assembly 42. The floor brake lifting assembly 41 can realize vertical lifting movement, and its lower end is connected to the universal wheel assembly 42. When it is necessary to change the movement mode of the vulcanizing trolley or adjust the position, the floor brake lifting assembly 41 is lifted. At this time, the universal wheel 421 on the universal wheel assembly contacts the ground 5, and the fixed wheel assembly 3 is separated from the track 2 and suspended in the air, so that the trolley can move flexibly in different directions. After the floor brake lifting assembly 41 is lowered, the fixed wheel assembly 3 is re-engaged with the track 2, and the lifting universal caster device 4 is suspended on the ground 5, restoring the stable driving state of the vulcanizing trolley on the track.

[0036] Specifically, the directional wheel assembly 3 includes a directional wheel bracket fixed to the lower end surface of the trolley body 1. This directional wheel bracket provides a stable mounting base for the directional wheel, ensuring that the directional wheel remains stable during operation. The directional wheel bracket is pivotally connected to the directional wheel bracket. This connection method allows the directional wheel to rotate flexibly, thereby ensuring smooth travel of the trolley on the track 2.

[0037] In this embodiment, there are two rails 2, which are arranged parallel to each other. Rails 2 are made of track channel steel, which has high strength and stability. Tracks 2 are embedded in the ground 5. This installation method not only makes the track more secure and less prone to displacement, but also ensures a smooth transition during the vehicle's travel, reducing bumps and shaking. The design of the track channel steel also facilitates coordination with the directional wheels, ensuring close contact between the wheel and rail, and improving transportation efficiency and safety. At the same time, the track embedded in the ground can save space, making the working environment more neat and orderly.

[0038] The lifting universal caster device 4 of this embodiment integrates the lifting function of a floor brake and the universal rolling function of a universal wheel. The lifting function of the floor brake is used to lift the entire vulcanizing trolley and maintain it, so that the fixed wheels of the vulcanizing trolley are separated from the track channel steel and above the ground. The vulcanizing trolley can then be moved to another location using the universal wheels that are in contact with the ground.

[0039] Specifically, the universal wheel assembly 42 includes a universal wheel 421 and a bearing 422. The bearing 422 is located on the upper end surface of the universal wheel 21 and provides both connection and support. The bearing 422 reduces friction, ensuring smoother rotation of the universal wheel. The inner tube of the floor brake lifting assembly 41 pivots within the bearing 422. This connection allows the floor brake lifting assembly 41 and the universal wheel assembly 42 to rotate relative to each other, ensuring the flexibility of the universal wheel during the lifting process.

[0040] The floor brake lifting assembly 41 in this embodiment is modified from an existing floor brake by removing the base of the original floor brake and retaining the lifting part of the floor brake. The existing floor brake can refer to patent (CN201506377U).

[0041] The floor brake lifting assembly 41 in this embodiment comprises a bracket portion with a top plate mounted on its upper end. The bracket portion comprises a movable portion and a main body. The main body comprises a support rod and an inner tube positioned on the support rod. The movable portion comprises an outer tube mounted on the inner tube and capable of sliding vertically. Furthermore, the assembly comprises a pedal connected to the bracket portion via a return brake. The pedal can drive the movable portion of the bracket portion to slide vertically. The pedal allows on-site personnel to conveniently perform raising and lowering operations on the floor brake lifting assembly 41.

[0042] Among them, in order to facilitate the on-site personnel to control the up and down movement of the lifting universal caster device 4 by stepping, an avoidance groove 11 is provided on the trolley body 1 above the lifting universal caster device 4. The design of this avoidance groove 11 is very practical, and it provides enough space for the on-site personnel, so that they can control the up and down movement of the lifting universal caster device 4 by stepping.

[0043] In this embodiment, anti-collision blocks 12 are provided at the corners of the trolley body 1. These anti-collision blocks can effectively protect the trolley body 1 and the lifting universal caster device 4. During actual use, the vulcanized trolley may be operated in a relatively crowded or complex working environment, and it is inevitable that it will collide with surrounding equipment and objects. The presence of anti-collision blocks can first withstand the impact force when a collision occurs, reducing the force directly acting on the trolley body and the lifting universal caster device. The anti-collision blocks are usually made of a material with a certain degree of elasticity and toughness, and can act as a buffer after being hit, reducing the damage caused by the collision to the trolley.

[0044] In this embodiment, a pair of handrails 13 are provided on the upper end of the trolley body 1. These handrails, located on both sides of the trolley body 1, facilitate transport of the vulcanizing trolley. When the trolley needs to be moved, the operator can grasp the handrails on either side to better control the direction and speed of movement.

[0045] The method of using the vulcanizing trolley of the utility model is as follows: when the vulcanizing trolley needs to be moved on the track, ensure that the floor brake lifting assembly is lowered, so that the directional wheel assembly cooperates well with the track, and the trolley body can be pushed to move smoothly along the track. When the trolley needs to be moved to an area outside the track or to flexibly adjust its position, operate the floor brake lifting assembly to lift it, and the universal wheel contacts the ground. At this time, the trolley can be freely pushed to the desired position. Through the application of the directional wheel assembly and the lifting universal caster device, there is no need to use a forklift or a ground bull for shifting operations. This design is particularly suitable for vulcanizing production workshops with relatively narrow space. It can make full use of limited space and avoid the inconvenience caused by site restrictions. Moreover, multiple vulcanizing trolleys can be shifted at the same time, which greatly improves production efficiency and provides a strong guarantee for the company's efficient production.
