[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0028] In one embodiment of this application:
[0029] like Figures 1 to 6 As shown, an opening and closing locking device for a wheel-rail circular tube belt conveyor includes a guide rail 6, a limiting device 3, and a locking carriage 5. The guide rail 6 is installed on the conveyor, and the locking carriage 5 is placed on the channel steel of the guide rail 6. The locking carriage 5 can move along the guide rail 6. A support frame 1 is provided on the guide rail 6, and a connecting rod 4 and a locking device 2 for opening the locking carriage 5 are provided on the support frame 1. The bottom of the connecting rod 4 is fixedly connected to the limiting device 3.
[0030] The support frame 1 includes a frame 11 and a support rod 12. The support rod 12 includes a first support rod and a second support rod. The first support rod and the second support rod are respectively fixedly installed on the inner bottom of the frame 11. The guide rail 6 includes a first guide rail and a second guide rail. The frame 11 is connected to the left side of the first guide rail through the first support rod, and the frame 11 is connected to the right side of the second guide rail through the second support rod.
[0031] The frame 11 is symmetrically provided with a first elongated hole and a second elongated hole. The connecting rod 4 includes a first connecting rod and a second connecting rod. The first connecting rod is connected to the first elongated hole, and the second connecting rod is connected to the second elongated hole. The limiting device 3 includes a first limiting device and a second limiting device. The bottom of the first connecting rod is connected to the first limiting device, and the bottom of the second connecting rod is connected to the second limiting device.
[0032] The first connecting rod is bolted to the first elongated hole, and the second connecting rod is bolted to the second elongated hole. If it is necessary to adjust the position of the first limiting device and the second limiting device, loosen the bolts, move the first connecting rod along the first elongated hole or the second connecting rod along the second elongated hole to adjust the position, and then tighten the bolts to fix it. This adjusts the position of the first limiting device and the second limiting device, and also facilitates the replacement of the damaged first connecting rod, the second connecting rod, the first limiting device, and the second limiting device.
[0033] The first limiting device includes a first limiting frame 32 and a second limiting frame. A first round steel bar 31 and a second round steel bar are respectively provided on the inner side of the first limiting frame 32 and the inner side of the second limiting frame. The first limiting frame 32 includes a first left limiting frame and a first right limiting frame, which are connected. The first right limiting frame tilts to the left along the direction of the first left limiting frame. The second limiting frame includes a second left limiting frame and a second right limiting frame, which are connected. The second right limiting frame tilts to the right along the direction of the second left limiting frame. The first and second right limiting frames are flared. The first and second limiting devices are respectively located on the left and right sides of the locking vehicle 5. The narrow end of the first limiting device is closest to the locking vehicle 5. Figure 6 As shown, the first limiting device and the second limiting device are slightly tilted upwards, that is, the height of the first left limiting frame and the second left limiting frame is lower than the height of the first right limiting frame and the second right limiting frame.
[0034] The first round steel bar 31 is welded and fixed to the first limiting frame 32, and the second round steel bar is welded and fixed to the second limiting frame.
[0035] The locking vehicle 5 includes a fixed arm 7, a locking arm, and a locking device 8. The locking arm includes a left locking arm 9 and a right locking arm 10. The fixed arm 7 is fixedly connected to the support plate 13. Rollers 14 are provided on both sides of the support plate 13. The rollers 14 can move along the guide rail 6. The left locking arm 9 is movably connected to one end of the fixed arm 7, and the right locking arm 10 is movably connected to the other end of the fixed arm 7. The left locking arm 9 and the right locking arm 10 are connected by the locking device 8.
[0036] The left locking arm 9 and the right locking arm 10 are movably connected to the fixed arm 7 through the return spring 19. The left locking arm 9 is provided with a left fixed rod 34, and the right locking arm 10 is provided with a right fixed rod 33.
[0037] The locking device 8 includes a locking hook and a locking spring. The locking hook includes a left locking hook 17 and a right locking hook 22. The locking spring includes a left locking spring 18 and a right locking spring 23. The left locking hook 17 is movably connected to the left locking arm 9 through the left locking spring 18. The right locking hook 22 is movably connected to the right locking arm 10 through the right locking spring 23. The left locking hook 17 hooks onto the right locking arm 10 for fixation, and the right locking hook 22 hooks onto the left locking arm 9 for fixation. The unlocking device 2 is aligned with the gap between the left locking arm 9 and the right locking arm 10.
[0038] The lock pick 2 is trumpet-shaped and slightly tilted upwards, meaning that the height of the narrow end of the lock pick 2 is lower than the height of the wide end, and the narrow end of the lock pick 2 is aligned with the gap between the left locking arm 9 and the right locking arm 10. When unlocking is required, the locking vehicle 5 moves forward, and the narrow end of the unlocker 2 slowly inserts into the gap between the left locking arm 9 and the right locking arm 10 of the locking vehicle 5. As the locking vehicle 5 moves forward, the unlocker 2 applies an upward force to the upper left locking hook 17 and right locking hook 22 until the left locking hook 17 separates from the right locking arm 10 and the right locking hook 22 separates from the left locking arm 9. The locking arms of the locking vehicle 5 open, and the left locking arm 9 separates from the right locking arm 10. The left fixing rod 34 of the left locking arm 9 is hung on the first limiting frame 32, and the right fixing rod 33 of the right locking arm 10 is hung on the second limiting frame. As the locking vehicle 5 moves forward, the locking arms are close to the limiting device 3 and gradually open along the first limiting frame 32 and the second limiting frame until they are fully open, effectively preventing the locking arms from opening too quickly and damaging the parts of the locking vehicle 5.
[0039] In another embodiment of this application:
[0040] Based on the previous embodiment, this embodiment improves upon the limiting device 3 and the unlocking device 2 by reversing their arrangement. Specifically, the wide end of the limiting device 3 is closest to the locking vehicle 5, and the wide end of the unlocking device 2 faces the locking vehicle 5. The reverse-positioned limiting device 3 is slightly tilted downwards, meaning the height of the first and second right limiting frames is higher than the height of the first and second left limiting frames. Similarly, the unlocking device 2 is slightly tilted downwards, meaning the height of its wide end is higher than its narrow end. In this configuration, it can be used as a locking device. The left side of the locking vehicle 5... The left fixing rod 34 of the locking arm 9 is hung on the first limiting frame 32, and the right fixing rod 33 of the right locking arm 10 is hung on the second limiting frame. As the locking vehicle 5 moves forward, the locking arm is close to the limiting device 3 and gradually closes along the first limiting frame 32 and the second limiting frame. After the locking arm is closed to a certain extent, the left locking hook 17 and the right locking hook 22 will be hooked on the unlocker 2, and then move along the unlocker 2 to the narrow end of the unlocker 2, and then fall down from the narrow end. The left locking hook 17 hooks the right locking arm 10, and the right locking hook 22 hooks the left locking arm 9, so that the locking arm is completely closed and locked.
[0041] Alternatively, the locking function can be achieved by running the locking car 5 in reverse without reversing the first limiting device, the second limiting device, and the unlocking device 2.
[0042] The above description is merely an embodiment of this utility model. It should be understood that this utility model is not limited to the form disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
