Description

Technical Field

[0001] The utility model relates to a transport device, in particular to a chain track anti-loosening and anti-breaking device. Background Art

[0002] Among the existing transportation methods, one is to use chains as track transmission.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0032] In the description of this embodiment, the terms "upper", "lower", "right", and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model.

[0033] In addition, the terms “first” and “second” are merely used for distinction in description and have no special meanings.

[0034] In order to monitor and adjust the tightness of chains at different positions, this embodiment provides a chain track anti-loosening and anti-breaking device.

[0035] As shown in the figure, the anti-loosening and anti-breaking device includes: an anti-loosening and anti-breaking detector 2, the anti-loosening and anti-breaking detector 2 includes a pointer 21, a connecting rod 22, a roller 23, and a roller connecting plate 24. The pointer 21 is installed on the connecting rod 22, and the pointer 21 can rotate on the connecting rod according to the tightness of the chain 1. One end of the connecting rod 22 is fixedly connected to the chain 1, and the other end is connected to the roller. The roller 23 can roll on the roller connecting plate 24. The anti-loosening and anti-breaking detector 2 is used to reflect the tightness of the chain 1. When the chain 1 is displaced, the roller 23 will also roll and move, and the pointer 21 will rotate to reflect the condition of the chain 1, and the condition includes the displacement, tightness, and breakage of the chain 1.

[0036] Furthermore, the anti-loosening and anti-breaking device also includes: a detector slider 25 and a detector base 26 . The roller connecting plate 24 is mounted on the detector slider 25 , and the detector slider 25 is mounted on the detector base 26 .

[0037] Furthermore, the anti-loosening and anti-breaking device also includes a transparent outer cover 27, and the transparent outer cover 27 is fixed on the roller connecting plate 24 and / or the detector base 26 to protect the anti-loosening and anti-breaking device.

[0038] In this embodiment, a ring is provided at the tail of the pointer 21, the connecting rod 22 is provided with a cylindrical protrusion, the transparent outer cover 27 is provided with a rotating column, the rotating column is provided with a through hole, the ring is mounted on the cylindrical protrusion, and the pointer 21 passes through the through hole. During the use of the anti-loosening and anti-breaking device, when the connecting rod 22 is displaced, the pointer 21 rotates with the center of the cylindrical protrusion as the center of the circle.

[0039] Furthermore, the detector slider 25 has a trapezoidal structure, and the detector base 26 is provided with a dovetail groove. The trapezoidal slider of the detector slider 25 cooperates with the dovetail groove. The detector slider 25 can slide relative to the detector base 26 through the dovetail groove to adjust the relative position of the roller connecting plate 24 and the detector base 26.

[0040] Furthermore, the anti-loosening and anti-breaking detector 2 includes an emergency stop switch 28, and the emergency stop switch 28 triggers shutdown when detecting that the tightness of the chain 1 reaches a preset safety value.

[0041] Furthermore, the emergency stop switch 28 is installed on the roller connecting plate 24. When the tightness of the chain 1 changes, the roller 23 will also move accordingly. When the tightness of the chain 1 reaches a safety threshold, the roller 23 contacts the emergency stop switch 28 and triggers shutdown.

[0042] Furthermore, the anti-loosening and anti-breaking device also includes a segmentation device 3, which is used to control and / or adjust the tightness of the chain 1. When the chain 1 breaks, the unbroken parts of the chain 1 between the segmentation devices 3 can maintain a certain tightness. When the tightness of a certain section of the chain 1 needs to be adjusted, it can be completed by adjusting the segmentation device 3 on this section of the chain 1.

[0043] Furthermore, the segmenting device 3 includes a connecting block 31, a buffer pad 32, a positioning slider 33, a bolt 34, a lock nut 35, a bolt support 36, and a base 37. One end of the connecting block 31 is fixedly connected to the chain 1, and the other end is connected to the buffer pad 32 on both sides. The positioning slider 33 is installed on both sides of the connecting block 31. The buffer pad 32 is installed between the connecting block 31 and the positioning slider 33. The positioning slider 33, the connecting block 31 and the buffer pad 32 are all installed on the bolt 34.

[0044] Furthermore, the bolt 34 is mounted on a bolt support 36 , a locking nut 35 is mounted on the bolt 34 , and the bolt support 36 is mounted on a base 37 .

[0045] Furthermore, the positioning slider 33 has a trapezoidal structure, and the base 37 is provided with a dovetail groove. The trapezoidal structure of the positioning slider 33 cooperates with the dovetail groove, and the positioning slider 33 can slide relative to the base 37 through the dovetail groove. By adjusting the position of the positioning slider 33 relative to the base 37, the tightness of the chain 1 can be adjusted. By fixing the positioning slider 33 with the bolt 34 and the anti-loosening nut 35, the tightness of the chain 1 can be indirectly fixed.

[0046] Furthermore, the segmenting devices 3 are arranged symmetrically in pairs with the chain 1 as the axis, and the anti-loosening and anti-breaking device is provided with N or N+1 anti-loosening and anti-breaking detectors 2. The number of the segmenting devices 3 is set to 2N, which can well play the role of monitoring, protecting, fixing and adjusting the tightness of the chain 1. When the length of the chain 1 is short, using one anti-loosening and anti-breaking detector 2 and two segmenting devices 3 can meet the requirements of monitoring, protection, fixing and adjustment. When the length of the chain 1 is long, multiple anti-loosening and anti-breaking detectors 2 and multiple segmenting devices 3 are required to meet the requirements of monitoring, protection, fixing and adjustment.

[0047] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
