Description

Technical Field

[0001] The present invention relates to the technical field of tire test equipment, and particularly relates to a high-speed tire endurance testing machine with a protective structure. Background Art

[0002] A high-speed tire endurance testing machine is used to simulate working conditions such as high-speed vehicle driving and extreme loads. The tire is driven to rotate at a high speed, usually >100 km / h, by a drum system, and a radial load is applied to evaluate key performances of the tire such as anti-fatigue property and anti-burst property. During this process, the tire is prone to burst due to internal stress concentration or material defects, generating high-speed flying fragments such as steel cord and rubber blocks, which pose serious safety hazards to operators and equipment.

[0003] Currently, there are already some prior arts that can prevent the fragments splashed by the tire from injuring the testers. Generally, a protective structure is set outside the testing machine. However, the traditional protective structures are mostly fixed metal baffles or partial enclosures, which cannot provide full-coverage protection for the outside of the testing machine, resulting in fragments being easily ejected from joints or observation windows, posing great safety hazards. In addition, most of the current protective structures require assembly and disassembly operations through bolts or other locking structures, which consume a large amount of time and manpower during assembly and disassembly, seriously affecting the detection efficiency of the tire. Based on this, the present invention provides a high-speed tire endurance testing machine with a protective structure that is simple and ingenious in structure and can ensure that tire fragments can be completely blocked during high-speed bursting. Summary of the Invention

[0004] The purpose of the present invention is to provide a high-speed tire endurance testing machine with a protective structure for the deficiencies of the prior art, so as to solve the technical problem that fragments are easily ejected from joints or observation windows, posing great safety hazards.

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0031] Please refer to Figures 1-5 As shown, the present invention is a high-speed endurance testing machine for tires with a protection structure, including:

[0032] A base 1, on which a tire testing machine body 2 and a protection mechanism 3 are provided. The protection mechanism 3 is used to protect the tire testing machine body 2 and is arranged on one side of the base 1. The tire testing machine body 2 is located inside the protection mechanism 3. The protection mechanism 3 includes a first protective cover body 31, a second protective cover body 32, a support plate 33, a linkage unit and a driving unit. The second protective cover body 32 is slidably clamped inside the first protective cover body 31. Both the first protective cover body 31 and the second protective cover body 32 are slidably connected to the base 1. The support plate 33 is fixed on one side of the base 1. The linkage unit is arranged between the first protective cover body 31 and the second protective cover body 32. The driving unit is arranged on the support plate 33; and

[0033] An isolation mechanism 4, which is used to isolate the open end of the second protective cover body 32, and the isolation mechanism 4 is arranged at one end of the second protective cover body 32 far from the first protective cover body 31.

[0034] In practical application of this embodiment, the movement of the first protective cover body 31 in the protection mechanism 3 drives the linkage of the belt 35, and then drives the second protective cover body 32 to synchronously link through the synchronous plate 36, forming a synchronous drive system, so that the first protective cover body 31 and the second protective cover body 32 can synchronously slide, and quickly form a protective structure that completely surrounds the outside of the tire testing machine body 2, eliminating the gaps in the traditional fixed baffle, and ensuring that tire fragments can be completely blocked when bursting at high speed; by setting the isolation mechanism 4, when the second protective cover body 32 slides to one end of the tire testing machine body 2, two adjacent isolation doors 41 can rotate synchronously through the pull rod 42, and isolate the open end of the second protective cover body 32 from the external environment, thereby further improving the protection coefficient of the protection mechanism 3 and preventing tire fragments from flying out from the open end of the second protective cover body 32. At the same time, the positioning rod 48 is docked with the adjusting plate 47 to form a self-locking structure, so that when the isolation door 41 needs to be unlocked, manual operation must be carried out manually, eliminating the risk of misoperation.

[0035] As Figures 3-4 shown, as a preferred embodiment of the present invention, the linkage unit includes a belt pulley 34, a belt 35 and a synchronous plate 36. The belt pulley 34 is rotatably connected to one end of the first protective cover body 31, and two belt pulleys 34 are symmetrically arranged. The belt 35 is arranged between two adjacent belt pulleys 34, and the bottom of the annular structure formed by the belt 35 is fixed to the support plate 33. One end of the synchronous plate 36 is fixed to the second protective cover body 32, and the other end is fixed to the top of the annular structure formed by the belt 35.

[0036] In practical application of this embodiment, by setting the belt 35, while the first protective cover body 31 moves, the belt 35 can drive the synchronous plate 36 to move synchronously under the limiting action of the support plate 33, and then drive the second protective cover body 32 to synchronously slide.

[0037] As Figures 1-5 shown, as a preferred embodiment of the present invention, the synchronous plate 36 is located above the first protective cover body 31, and a strip-shaped notch is penetrated at the edge of the first protective cover body 31. The connection end of the synchronous plate 36 and the second protective cover body 32 passes through the strip-shaped notch and is slidably connected in the strip-shaped notch.

[0038] As Figure 5 shown, as a preferred embodiment of the present invention, the drive unit includes a rack 37, a transmission rod 38 and a gear 39. The rack 37 is fixed to the bottom of the side wall of the first protective cover body 31. The transmission rod 38 is rotatably connected to the support plate 33. The gear 39 is coaxially fixed to one end of the transmission rod 38 and meshes with the rack 37.

[0039] In one case of this embodiment, the driving unit further includes a worm gear 310, a servo motor 311, and a worm 312. The worm gear 310 is coaxially fixed to one end of the transmission rod 38 away from the gear 39. The servo motor 311 is fixed to the support plate 33. The worm 312 is coaxially fixed to the output shaft of the servo motor 311 and meshes with the worm gear 310.

[0040] In actual application of this embodiment, the servo motor 311 is used to drive the worm 312 to rotate, thereby driving the worm gear 310 to engage and link, and driving the transmission rod 38 to rotate. Then, the rotation of the gear 39 causes the rack 37 to engage and link, thereby driving the first protective cover 31 to slide quickly.

[0041] As Figures 1-5 shown, as a preferred embodiment of the present invention, rollers 313 are rotatably connected inside both the first protective cover 31 and the second protective cover 32. A guide rail 314 is fixed on the base 1. The rollers 313 are rollingly clamped on the guide rail 314.

[0042] In actual application of this embodiment, rollers 313 are rotatably connected inside both the first protective cover 31 and the second protective cover 32. A guide rail 314 is fixed on the base 1. The rollers 313 are rollingly clamped on the guide rail 314. The arrangement of the rollers 313 enables the protective cover to slide quickly, and the guide rail 314 guides its moving direction.

[0043] As Figure 4 shown, as a preferred embodiment of the present invention, a guide rod 315 is fixed at the top edge of the first protective cover 31. The synchronization plate 36 is slidably clamped on the guide rod 315.

[0044] As Figures 1-7 shown, as a preferred embodiment of the present invention, the isolation mechanism 4 includes an isolation door 41 and a pull rod 42. The isolation door 41 is rotatably connected to the open end of the second protective cover 32 and there are two symmetrically arranged. A convex block is fixed on one of the isolation doors 41. One end of the pull rod 42 is rotatably connected to the convex block, and the other end is rotatably connected to the other isolation door 41, and the pull rod 42 is inclined.

[0045] In one case of this embodiment, the isolation mechanism 4 further includes a fixing plate 43, a driven plate 44, and a passive plate 45. The fixing plate 43 is horizontally fixed on the inner wall of the second protective cover 32. One end of the driven plate 44 is rotatably connected to the fixing plate 43. One end of the passive plate 45 is rotatably connected to the bottom of the driven plate 44, and the other end is rotatably connected to one of the isolation doors 41.

[0046] In actual application of this embodiment, the rotation of the driven plate 44 drives the passive plate 45 to move in conjunction, and then the passive plate 45 drives the isolation door 41 to open and close quickly, and the pull rod 42 is used to enable two adjacent isolation doors 41 to rotate synchronously.

[0047] like Figures 1-7 As shown, as a preferred embodiment of the present invention, the isolation mechanism 4 also includes a limit seat 46, an adjustment plate 47, a positioning rod 48 and a reset member 49. The limit seat 46 is fixed on the inner wall of the second protective cover body 32 close to the side of the fixed plate 43, the adjustment plate 47 is rotatably connected to the limit seat 46, and one end of the adjustment plate 47 passes through the second protective cover body 32, and the other end is penetrated by a through hole, the positioning rod 48 is connected to one end of the driven plate 44 away from the fixed plate 43, and the positioning rod 48 is clamped in the through hole, and the reset member 49 is arranged between the limit seat 46 and the adjustment plate 47.

[0048] In actual application of this embodiment, the positioning rod 48 is connected to the adjustment plate 47, so that after the isolation door 41 is closed, a self-locking structure can be formed to prevent the isolation door 41 from opening due to accidental touch.

[0049] Working principle of the present invention: The above embodiment of the present invention provides a tire high-speed endurance tester with a protective structure. First, the tire to be tested is installed in the tire tester body 2. At this time, the second protective cover body 32 is retracted in the first protective cover body 31, and the second protective cover body 32 is located on one side of the tire tester body 2. At the same time, the isolation door 41 is in an open state. After the tire is installed, the servo motor 311 is started to drive the worm 312 to rotate, so that the worm wheel 310 is meshed and linked. At this time, the gear 39 is rotated through the transmission rod 38, and the gear 39 drives the rack 37 to mesh and link, so that the first protective cover body 31 slides as a whole. While sliding, the belt 312 is driven to rotate. Under the limiting effect of the support plate 33, the synchronous plate 36 is driven to move in linkage, and the synchronous plate 36 drives the second protective cover body 32 to slide synchronously, thereby making the first protective cover body 31 and the second protective cover body 32 move synchronously as a whole, until the tire testing machine body 2 is completely covered inside the cover body; then the isolation door 41 is rotated, and the passive plate 45 drives the driven plate 44 to rotate, and the positioning rod 48 is abutted against the adjustment plate 47, so that it is clamped in the through hole of the adjustment plate 47 to form a self-locking structure. When unlocking is required, the end of the adjustment plate 47 located outside the second protective cover body 32 is manually pressed to lift it up, and the adjustment plate 47 is separated from the positioning rod 48.

[0050] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
