[0003] During the production process of off-road tires, they need to go through a vulcanization process. After the tires are vulcanized, they are moved to a conveyor belt by a robot and gradually cooled. Then, workers use a U-shaped transport trolley ( Figure 3 The U-shaped transport trolley is used to pick up the tire with the lifting frame fixed at the end of the conveyor belt. Finally, the worker moves the tire to the hair removal area for manual hair removal to remove the hair on the tire.

[0004] Since the tires are placed flat on the U-shaped transport trolley, the off-road tires need to be placed upright after arriving at the hair removal area to facilitate the workers to hair removal. However, off-road tires are heavy and generally require electric hoists to assist in lifting; it is time-consuming and labor-intensive, and requires two people to cooperate with each other to achieve the tire upright, and there are safety hazards.

[0035] like Figures 1-2 As shown, the utility model provides a turning device 10 for standing off-road tires, comprising a base frame 110, a turning frame 120, a cylinder 130, two guardrails 140, an anti-dumping frame 150, a safety protection module and a control cabinet 170;

[0036] The base frame 110 is disposed on the ground and is fixed by bolts.

[0037] The flip frame 120 is arranged on the top of the base frame 110, and the rear end of the flip frame 120 is rotatably connected to the rear end of the base frame 110 through a rotating shaft 131, and the length of the flip frame 120 is greater than the length of the base frame 110; in an initial state, the flip frame 120 is horizontally arranged on the top of the base frame 110, and under the push of the cylinder 130, the flip frame 120 can rotate around the rotating shaft 131 as the axis.

[0038] A roller mounting frame 121 is disposed on the upper surface of the turning frame 120 , and a plurality of rollers 122 are disposed on the roller mounting frame 121 , and the intervals between two adjacent rollers 122 are equal.

[0039] In one embodiment, there is one roller mounting frame 121 disposed on the upper surface of the turning frame 120 , and the width of the roller mounting frame 121 is equal to or slightly smaller than the width of the turning frame 120 .

[0040] In one embodiment, if Figure 1 As shown; there are two roller mounting frames 121, the width of which is much smaller than the width of the turning frame 120, the two roller mounting frames 121 are respectively arranged on both sides of the upper surface of the turning frame 120, and the two roller mounting frames 121 are arranged in parallel; a plurality of rollers 122 are evenly spaced on the two roller mounting frames 121.

[0041] The bottom end of the cylinder 130 is rotatably connected to the base frame 110 via a rotating shaft 131, and the end of the piston rod of the cylinder 130 is rotatably connected to the front middle part of the flip frame 120 via the rotating shaft 131; in an initial state, the flip frame 120 is horizontally arranged; when the piston rod of the cylinder 130 is extended, the flip frame 120 will rotate around the rotating shaft 131.

[0042] The two guardrails 140 are respectively arranged on the left and right sides of the base frame 110, and the two guardrails 140 are symmetrically arranged; on the one hand, the guardrails 140 prevent the off-road tires from accidentally rolling out from both sides and injuring people when they are placed upright, and on the other hand, they also prevent people from mistakenly entering the work area during the standing process, causing safety accidents.

[0043] The anti-dumping frame 150 is arranged at the rear of the base frame 110, and the distance between the anti-dumping frame 150 and the end of the base frame 110 is 1 to 1.5 meters. The anti-dumping frame 150 is to prevent the off-road tire from tipping over to the other side when the off-road tire is placed upright, which may cause a safety accident. When the off-road tire is placed upright, the worker can push the off-road tire out of the gap between the anti-dumping frame 150 and the guardrail 140 to facilitate the subsequent hair removal operation.

[0044] The safety protection module includes two photoelectric switches A161, two photoelectric switches B162 and four reflectors 163; the two photoelectric switches A161 are respectively arranged at the ends of the two guardrails 140, and the two reflectors 163 are arranged on the anti-tipping frame 150 and correspond one-to-one with the two photoelectric switches A161 to detect whether someone enters the tire flipping area from the gap between the anti-tipping frame 150 and the guardrail 140.

[0045] The two photoelectric switches B are both set at the starting end of one guardrail 140 and arranged up and down; the starting end of the other guardrail 140 is provided with two reflectors 163 and correspond one to one with the two photoelectric switches B162; the two photoelectric switches B are used to detect whether someone enters the turning frame working area from the starting end of the guardrail 140.

[0046] The photoelectric switch A161 and the photoelectric switch B162 are used to prevent personnel from mistakenly entering the working area of ​​the turning frame during operation to avoid safety accidents. When the photoelectric switch A161 and / or the photoelectric switch B162 is triggered, a signal is sent to the control cabinet 170, thereby stopping the operation of the turning device 10 and sounding an alarm.

[0047] The control cabinet 170 includes a solenoid valve A, two solenoid valves B, a plurality of buttons 171, a control module and an alarm light 172; the solenoid valve A controls the total air source, the two solenoid valves B are connected to the solenoid valve A through pipelines, and the two solenoid valves B are respectively connected to the air inlet and the air outlet of the cylinder 130, so as to directly and accurately control the extension and contraction of the cylinder 130; the control module is the control core of the flip device 10, and is respectively connected to the solenoid valve A, the solenoid valve B, a plurality of buttons 171, the alarm light 172, the photoelectric switch A161 and the photoelectric switch B162. The worker controls the opening and closing of each solenoid valve B through the button 171 to complete the upright placement action of the off-road tire and the restoration action of the flip device 10, and can also control the solenoid valve A through the button 171 to close or start the flip device 10; when the photoelectric switch A161 and the photoelectric switch B162 detect that someone or something enters the working area, a signal will be sent to the control module, thereby controlling the alarm light 172 to sound and the solenoid valve A to close, so as to prevent the occurrence of safety accidents. The control module adopts the existing technology, that is, those skilled in the art can implement the various functions of the control module according to the description in this article without paying any creative work, so its principle and structure will not be described in detail.

[0048] Furthermore, the control module may be a single chip microcomputer, a PLC controller or a relay circuit.

[0049] Specifically, the method of using the utility model is:

[0050] After the tire is vulcanized, it is pushed here by the U-shaped transport trolley 20, and the tire falls on the turning frame 120. The worker presses the turning button 171, the solenoid valve B is actuated, the control cylinder 130 is extended, the turning frame 120 is gradually erected, and the tire is thus erected;

[0051] When the worker enters and prepares to push out the tire, the photoelectric switch A161 of the safety protection system is triggered, and the solenoid valve B cuts off the air supply to play a protective role.

[0052] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
