Description

Technical Field

[0001] The present invention belongs to the technical field of flipping equipment, and more specifically, relates to a mechanical safety fool-proofing mechanism for flipping equipment and a flipping equipment including the mechanical safety fool-proofing mechanism. Background Art

[0002] In the machinery industry, it is inevitable that there will be mechanical safety issues. For example, in rotary motion mechanisms, linear motion mechanisms, and vertical motion mechanisms, when the drive system or brake system fails, the mechanism in high-speed motion will continue to move forward due to inertia, while in the vertical motion mechanism, due to its own gravity, the mechanism will fall down. At this time, if there is no safety anti-fool mechanism, a collision accident is very likely to occur. Moreover, in some suspension equipment, if the parts or mechanisms supporting the suspended objects fail, causing the suspended objects to fall, there will be safety hazards if there is no safety anti-fool mechanism. Therefore, a safety anti-fool mechanism is more needed in large-scale flipping mechanisms. If there is no safety anti-fool mechanism, the safety hazards are very large, so it is very necessary to add a safety anti-fool mechanism.

[0003] At present, the existing scheme uses a servo motor with a brake for foolproofing. Although it can solve the safety foolproofing of sudden power failure or software communication abnormality, it cannot prevent the sudden abnormality of the electric cylinder telescopic rod breaking, so it cannot protect against this safety hazard. In addition, the existing scheme uses a screw with a brake transmission method for foolproofing, but its transmission efficiency is too low and cannot meet the demand. And when the flip frame is maintained or adjusted, a support rod is used for support and fixation. Although its structure is simple, it is difficult to operate and has the disadvantages of a small rotation angle of the compatible flip frame, which increases its maintenance cost.

[0004] Therefore, it is urgent to design a mechanical safety anti-mistake mechanism that can solve the above technical problems. Summary of the invention

[0027] In one embodiment of the present invention, the latch hole includes a plurality of latch holes located at a plurality of different angular positions, and every two latch holes are arranged at an angle of 15°.

DETAILED DESCRIPTION

[0037] In order to more clearly understand the above-mentioned purposes, features and advantages of the present disclosure, the embodiments of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0039] like Figure 1 As shown, an embodiment of the present invention provides a mechanical safety anti-fool mechanism 9 for a flipping device, comprising: a fixed seat 1, a blocking latch shaft 2, a driving device 3, a fixed plate 4, a floating plate 5, a buffer glue 6 and a sleeve 7. The blocking latch shaft 2 is telescopically installed in the sleeve 7 and fixed on the top of the fixed seat 1 together with the sleeve 7. One end of the fixed plate 4 is fixedly connected to the sleeve 7 and the other end is fixedly connected to the driving device 3. The driving device 3 is drivingly connected to the blocking latch shaft 2, and the telescopic rod of the driving device 3 is fixedly connected to the floating plate 5, which is in turn fixedly connected to the blocking latch shaft 2, and a buffer glue 6 is also arranged between the floating plate 5 and the sleeve 7.

[0040] When the mechanical safety foolproof mechanism 9 is used, Figure 1-4 As shown, the driving device 3 is started, and its telescopic rod can drive the blocking latch shaft 2 to extend and retract. When the blocking latch shaft 2 is extended, the blocking latch shaft 2 is inserted into the latch hole 14 on the rotating arm 12 of the flipping device that is matched with it, thereby playing a limiting role and further playing an anti-fool effect.

[0041] In the above embodiment of the present invention, the driving device 3 includes any one of a cylinder, a motor and an electric cylinder. Preferably, the driving device 3 is a cylinder, whereby the blocking bolt shaft 2 is driven to extend and retract through the cylinder. Of course, the driving device 3 can also be other parts that can drive the blocking bolt shaft 2 to move, and the number and position of the blocking bolt shaft 2 and the driving device 3 can be arbitrarily set according to requirements.

[0042] In the above embodiment of the present invention, the turning device comprises a large-scale 90° turning device, that is to say, the mechanical safety foolproof mechanism in the above embodiment is suitable for a large-scale 90° turning device.

[0043] like Figure 2 As shown, Figure 2 An embodiment of the present invention is shown in which a Figure 1 The structural diagram of the flipping device with the mechanical safety anti-mistake mechanism is shown in FIG. In this embodiment, the flipping device includes: a base 8, a mechanical safety anti-mistake mechanism 9, an electric cylinder assembly 10 and a flipping frame 11. The electric cylinder assembly 10 is fixedly mounted on one end of the base 8 ( Figure 2 The flip frame 11 is supported on the other end of the base 8 ( Figure 2 The turning frame 11 is connected to the telescopic rod of the electric cylinder assembly 10 through the rotating arm 12. The mechanical safety foolproofing mechanism 9 is fixed on the base 8 and arranged adjacent to the rotating arm 12, and the mechanical safety foolproofing mechanism 9 is connected to the industrial computer (not shown) and the manual switch (not shown).

[0044] The above-mentioned embodiment of the present application can play a fool-proof role when the telescopic rod of the electric cylinder assembly 10 is broken, as follows:

[0045] In this embodiment, when the telescopic rod of the electric cylinder assembly 10 is extended, the telescopic rod of the electric cylinder assembly 10 drives the flip frame 11 to flip from the vertical direction to the horizontal direction, and when the telescopic rod of the electric cylinder assembly 10 is retracted, the telescopic rod of the electric cylinder assembly 10 drives the flip frame 11 to flip from the horizontal direction to the vertical direction;

[0046] When the telescopic rod of the electric cylinder assembly 10 is extended or retracted, if the telescopic rod of the electric cylinder assembly 10 suddenly breaks, the output torque of the electric cylinder monitored by the industrial computer will suddenly drop abnormally, and the industrial computer will feed back this abnormal signal to the mechanical safety anti-fool mechanism 9, and then the driving device 3 (preferably a cylinder) on the mechanical safety anti-fool mechanism 9 will respond quickly, the cylinder will extend, and then push the blocking pin shaft 2 to extend, and the blocking pin shaft 2 will quickly insert into the pin hole 14 on the rotating arm 12, so as to limit the naturally fallen rotating frame 11 and prevent the rotating frame 11 from falling.

[0047] Of course, in the above embodiment, a control device similar to an industrial computer with a sensor or other inductor to transmit signals can also be used to monitor and prevent foolishness, and its working principle is the same as that of the above industrial computer.

[0048] The above embodiments of the present application can play a fool-proof role when the flip device is maintained or adjusted, as follows:

[0049] When the flip frame 11 needs maintenance or adjustment, the electric cylinder assembly 10 is used to control the flip frame 11 to rotate to the required angle, and the manual switch is used to control the driving device 3 (cylinder) of the mechanical safety anti-mistake mechanism 9 to extend, so that the blocking latch shaft 2 extends and extends into the latch hole 14 on the rotating arm 12, thereby fixing or limiting the flip frame 11 to prevent emergencies during maintenance or adjustment.

[0050] Therefore, the above-mentioned design of the present invention can realize automatic and semi-automatic fool-proofing: when the turning frame 11 rotates normally, the mechanical safety fool-proofing mechanism 9 can realize automatic monitoring to prevent fool-proofing. When the turning equipment needs maintenance or adjustment, the mechanical safety fool-proofing mechanism 9 can also be manually controlled according to needs to prevent fool-proofing.

[0051] like Figure 3 As shown, Figure 3 An embodiment of the present invention is shown in which a Figure 1 The schematic diagram of the structure of the flipping device of the mechanical safety foolproof mechanism is shown in detail, which shows the arrangement of the latch holes at multiple angles on the rotating arm. In this embodiment, the design of the present invention can be compatible with multiple angles of the flip frame 11. For example, the latch holes 14 at multiple angles can be designed according to the needs and the position on the rotating arm 12, so as to meet the foolproof angle of the flip frame 11. Figure 3 As shown, the latch holes 14 include a plurality of latch holes 14 located at a plurality of different angular positions, and every two latch holes 14 are arranged at an angle of 15°.

[0052] like Figure 4 As shown, Figure 4 Another embodiment of the present invention is shown. Figure 1 The structure of the flip device of the mechanical safety anti-fool mechanism is shown in FIG. Figure 2The mechanism shown is similar, except that two mechanical safety anti-fool mechanisms 9 are fixedly installed on the base 8 at a position adjacent to the rotating arm 12. When the telescopic rod of the electric cylinder assembly 10 breaks, the two mechanical safety anti-fool mechanisms 9 can be driven to extend by controlling the driving devices 3, and then the respective blocking latch shafts 2 are pushed out, and the corresponding blocking latch shafts 2 are quickly inserted into the corresponding latch holes 14 on the rotating arm 12, so as to better limit the naturally falling rotating frame 11 and prevent the rotating frame 11 from falling. When the flipping equipment is maintained or adjusted, after the electric cylinder assembly 10 controls the flipping frame 11 to rotate to the required angle, the two mechanical safety anti-fool mechanisms 9 can be driven to extend by controlling the driving devices 3, and then the respective blocking latch shafts 2 are pushed out, and the corresponding blocking latch shafts 2 are quickly inserted into the corresponding latch holes 14 on the rotating arm 12, so as to more firmly fix or limit the flipping frame 11 and prevent emergencies during maintenance or adjustment. In this embodiment, one more mechanical safety foolproof mechanism 9 is used. Two mechanical safety foolproof mechanisms 9 have a more obvious foolproof effect on the flipping device and can better eliminate potential safety hazards. Of course, if the installation space allows, more mechanical safety foolproof mechanisms 9 can also be further set or installed.

[0053] It can be seen that the safety anti-fool mechanism of the present invention can utilize automatic and semi-automatic functions, which can not only play a high-safety anti-fool role for emergencies such as the breakage of the telescopic rod of the electric cylinder, but also can replace the fixed anti-fool role of the existing support rod. In addition, the present invention has a compact and simple structure and is easy to use. It not only improves the safety of the equipment, but also improves maintenance efficiency and reduces maintenance costs.
