Description

Technical Field

[0001] This application relates to the field of tire conveying technology, and more particularly to a tire conveying trolley. Background Technology

[0002] The X-ray inspection machine for engineering tires is used to inspect the quality of engineering tires. This equipment can detect defects in the internal structure of the tire. The equipment consists of two main parts: the main unit (enclosed in a radiation protection chamber) and a conveyor trolley. The main unit's primary function is to perform X-ray inspection on the tires; the conveyor trolley's role is to transport the tires into the main unit for X-ray inspection. Workers operate a crane to lift the tires onto the conveyor trolley, which then transports the tires into the main unit. The outer circumference of the tire is positioned at the center of the trolley body due to the "V"-shaped structure. However, the "V"-shaped structure on the trolley's surface is not adjustable, resulting in different fits for tires of different outer diameters and poor stability. To prevent the tires from tilting on the trolley, a "V"-shaped guardrail is installed on one side of the trolley, allowing the tires to lean against it and reducing tilting. During tire transport, the lack of tire fixation causes tire displacement on the trolley body; the magnitude of displacement varies for different tire sizes, and there is a risk of tire tilting. Furthermore, the tire was leaning against the guardrail, causing it to be out of center of the trolley. As a result, the tire was not centered when it was transported to the main unit. The centering device inside the main unit needed to reposition the tire to the center of the main unit to achieve the correct detection position. Summary of the Invention

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0020] It should be noted that, unless otherwise defined, the technical or scientific terms used in one or more embodiments of this specification should have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0021] To facilitate understanding of the tire transport trolley provided in this application embodiment, its application scenario is first described. The tire transport trolley provided in this application embodiment is used for transporting tires. Existing transport devices cannot be matched with tires of various outer diameters for autonomous adjustment, and the center positioning is inaccurate, posing a risk of tipping during transportation. Therefore, this application embodiment provides a tire transport trolley that can match tires of various outer diameters for autonomous angle adjustment and can be laterally translated to adjust its position, while also satisfying the positioning and clamping of the tires, avoiding the risk of tipping during transportation.

[0022] When the tires are unloaded from the transport vehicle and moved into the main unit for X-ray inspection, workers operate an overhead crane to hoist the tires onto a transport trolley, which then transports the tires into the main unit. The outer circumference of the tire is positioned at the center of the trolley body due to its "V"-shaped structure. However, the "V"-shaped structure on the trolley's surface is not adjustable, resulting in varying degrees of fit for tires of different outer diameters and poor stability. To prevent the tires from tilting on the trolley, a "V"-shaped guardrail is installed on one side of the trolley, allowing the tires to lean against it and reduce tilting. During tire transport, the lack of tire anchorage causes displacement on the trolley body, with different tire sizes exhibiting varying degrees of displacement, and there is a risk of tire tilting. Furthermore, the tires leaning against the guardrail prevent them from being centered on the trolley, resulting in them not being centered upon arrival at the main unit. The main unit's internal centering device then repositions the tires to the correct inspection position.

[0023] Therefore, the tire transport trolley provided in this application embodiment also includes a trolley body, which is used to autonomously adjust the positioning angle for tires of different outer diameters and avoid the risk of tilting by relative clamping. The tire transport trolley will be described in detail below with specific examples.

[0024] refer to Figure 1 As shown, Figure 1 This illustration shows a side view of a tire transport trolley provided in an embodiment of this application. The tire transport trolley is used in conjunction with an X-ray inspection machine to inspect tires 400. The tire transport trolley includes a trolley body 100, which is used to transport the trolley body 100 along a track to the inside of the main unit. The trolley body 100 stably transports engineering tires via a power drive system. Because engineering tires come in various models and large-diameter engineering tires have a large single weight, existing transport trolleys require tilting the tires 400 during transport, and the accommodation angle for tires 400 with different outer diameters cannot be adjusted, resulting in poor stability. Therefore, the trolley body 100 in this application is equipped with a flip-plate assembly for conforming to the outer wall of the tire 400, a roller group on the flip-plate assembly for translating the tire 400, and a tire clamping device for clamping and fixing the outer wall of the tire 400 in a relative clamping manner to prevent tipping. By integrating multiple devices into the assembly, the trolley body 100 in this application can stably transport tires 400 with various outer diameters, and the center positioning is standardized, reducing the need for subsequent position adjustment procedures.

[0025] Specifically, in combination Figure 2 As shown, the tire transport trolley also includes flip-plate assemblies that are rotatably connected relative to each other along the length of the trolley body 100. Between the two flip-plate assemblies is a V-shaped mounting groove that fits against the outer circular wall of the tire 400 and whose angle can freely change. After the tire 400 is placed, the two flip-plate assemblies automatically adjust their tilt angle to fit against the outer circular wall of the tire 400 in a mirror-like manner. Furthermore, both flip-plate assemblies can be adjusted to fit tires 400 with different outer diameters, resulting in stronger adaptability.

[0026] The inner walls of the two flap assemblies facing each other are rotatably connected to roller sets that roll in contact with the outer wall of the tire 400. The roller sets on both sides cooperate to form roller sets for the translation of the tire 400. The two flap assemblies are initially in a relatively inclined state, and there is a V-shaped mounting groove with a large angle between the two flap assemblies in the initial state. During the placement of the tire 400, as its own weight increases, the flap assemblies on both sides flip inward synchronously, completing the fit with the outer circular wall of the tire 400. The tire 400 can freely slide and translate to a designated position on the roller sets, and has a good positioning function.

[0027] Each flap assembly in this application includes: a flap 200 hinged to the trolley body 100, and a roller assembly rotatably connected to the flap 200; wherein the roller assembly has multiple rotating rollers 210 arranged along the length of the flap 200. The two flaps 200 are spaced apart by a certain gap, initially forming a recess to accommodate the tire 400. During the placement of the tire 400, as its own weight increases, the angle of the V-shaped mounting groove between the two flaps 200 continuously decreases until the maximum area conforms to the outer wall of the tire 400. Furthermore, to enable the two flaps 200 to autonomously adjust and rotate to a symmetrical angle under the pressure of the tire 400's own weight, the flaps 200 in this application are connected to the trolley body 100 via multiple hinges 110. This ensures the stability of the connection and the synchronicity of angle changes.

[0028] Combined Figure 2 and Figure 3 As shown, the tire transport trolley in this application also includes a tire clamping device that slides along the width direction of the trolley body 100. This clamping device is used to position the two outer sidewalls of the tire 400, ensuring that the tire 400 does not tilt during transport by clamping and fixing it, and that the center point positioning does not require readjustment, thus meeting positioning and transport requirements. Specifically, the clamping device includes two opposing clamping plates 300 and screw drive assemblies connecting the two clamping plates 300 respectively. It should be understood that the tire 400 requires lateral translation and position adjustment on multiple roller sets; therefore, a screw drive assembly is connected to each clamping plate 300. When the tire 400 deviates from the center position of the flipper 200, the movement strokes of the corresponding clamping plates 300 driven by the two screw drive assemblies are inconsistent. Therefore, the screw drive assemblies independently drive the two clamping plates 300 to move closer or further apart.

[0029] When both clamping plates 300 are slidably connected to the trolley body 100, the trolley body 100 is symmetrically provided with slide rails along the width direction, and each of the two clamping plates 300 is provided with a sliding block that cooperates with the slide rail. This satisfies the sliding requirements, and the distance between the two flip plates 200 is greater than the sliding width of the clamping plates 300, thereby enabling the flip plates 200 to position the outer circular wall of the tire 400, and the two clamping plates 300 to position the outer side wall of the tire 400 in a relative motion manner.

[0030] The lead screw drive assembly includes a lead lever 340 rotatably connected to the trolley body and a drive motor 310 for driving the lead lever 340 to rotate; wherein the drive motor 310 is connected to the lead lever 340 via a coupling 320. Each clamping plate 300 is provided with a ball screw nut pair 330 that is threadedly engaged with the corresponding lead lever 340. By driving the lead lever 340 to rotate, the corresponding clamping plate 300 is driven to move along the slide rail, and the two clamping plates 300 cooperate to clamp and release the tire 400. Preferably, in this application, the tire 400 is located at the center position of the two flip plates 200, the drive motors 310 used on both sides have the same rotation speed, the lead levers 340 used have the same pitch, and the tire clamping device has the same movement distance, realizing the center positioning function on the trolley body 100. Moreover, the tire clamping device clamps the tire 400, and the tire 400 will not shake during the transportation process, solving the problem of the tire 400 tilting during transportation.

[0031] In this application, two flip-plate assemblies are distributed in a mirror image and can rotate relative to each other to adjust the positioning angle, which can adapt to tires 400 with different outer diameters to achieve outer wall fitting and positioning. At the same time, the roller group can make the tire 400 lateral displacement to ensure multi-directional position adjustment. The two clamping plates 300 are slidably arranged relative to each other and move independently to clamp the outer wall of the tire 400, effectively preventing the tire 400 from tilting to the side. The overall positioning and transportation is safe and reliable.
