[0024] Embodiment

[0025] As Figures 1-3 shown, a tensioner cover removal tool includes a wrench 1 and a fixed plate 2, the fixed plate 2 is composed of two semicircular ring-shaped plate members, the two plate members are connected on one side through a hinge, the other side of the two plate members is provided with a lock catch 4 at the top, the inner side wall of the two plate members is provided with a rubber sleeve 3, the bottom of the fixed plate 2 is rotatably provided with an inner gear ring 7 and an outer gear ring 9, the inner gear ring 7 and the outer gear ring 9 are coaxially arranged with the fixed plate 2, the radius of the inner gear ring 7 is smaller than the radius of the outer gear ring 9, the tooth surface of the inner gear ring 7 is oppositely arranged with the tooth surface of the outer gear ring 9, the inner gear ring 7 and the outer gear ring 9 are both composed of two half gear rings, and a plurality of gear wheels 8 are engaged between the inner gear ring 7 and the outer gear ring 9.

[0026] Specifically, the gear wheel 8 is separable from the inner gear ring 7 and the outer gear ring 9 in the up-down direction, the bottom of the gear wheel 8 is detachably provided with an inner hexagonal wrench 13 through a plug-in assembly, and the wrench 1 is fixedly arranged on the outer side wall of the outer gear ring 9 in the radial direction.

[0027] It is worth noting that the wrench 1 provides a point for the worker to apply force, enabling the external gear ring 9 to rotate, thus saving effort. The fixing plate 2 fixes the removal tool to the shaft inside the tensioning sleeve, and also provides a fixing point for the internal gear ring 7 and the external gear ring 9. The rotation of the external gear ring 9 drives the gear 8 to rotate, and the internal gear ring 7 supports and positions the gear 8. The gear 8 drives the internal hex wrench 13 to rotate, and the internal hex wrench 13 is inserted into the bolt on the tensioning sleeve to loosen the bolt. Specifically, the two plates of the fixing plate 2 are opened and clamped onto the shaft inside the tensioning sleeve. The locking buckle 4 can fix the two plates into a whole. The rubber sleeve 3 can adapt to shafts of different sizes, so that the fixing plate 2 does not rotate relative to the shaft. The rotation of the wrench 1 drives the external gear ring 9 to rotate, and the external gear ring 9 can simultaneously drive several gears 8 to rotate. The internal gear ring 7 rotates in the same direction to support the gears 8. Several gears 8 drive several internal hex wrenches 13 to rotate, loosening the bolts on the tensioning sleeve at the same time.

[0028] In particular, the number of gears 8 is not fixed and can be increased or decreased according to the number of bolts on the tensioning sleeve that need to be removed, so that gears 8, internal hex wrench 13 and bolts are matched one by one.

[0029] In some feasible embodiments, the hinge is fixedly mounted on the side wall of the fixing plate 2, so that the two plates of the fixing plate 2 can be separately sleeved on the shaft.

[0030] In some feasible embodiments, the bottom of the fixing plate 2 is provided with a first sliding groove and a second sliding groove, both of which are annular sliding grooves. The top of the inner gear ring 7 is provided with a plurality of first sliders 5 that match the first sliding groove, and the top of the outer gear ring 9 is provided with a plurality of second sliders 6 that match the second sliding groove.

[0031] In some feasible embodiments, a plurality of first sliders 5 are spaced apart on the top of the inner gear ring 7, and a plurality of second sliders 6 are spaced apart on the top of the outer gear ring 9. When it is necessary to remove the fixing plate 2 from the shaft, the spaced first sliders 5 and second sliders 6 will not affect the opening of the two plates of the fixing plate 2.

[0032] In some feasible embodiments, the first slider 5 and the second slider 6 have a structure that is larger at the top and smaller at the bottom, and the first slide groove and the second slide groove also have a structure that is larger at the top and smaller at the bottom, so as to prevent the inner gear ring 7 and the outer gear ring 9 from falling off the fixed plate 2 when rotating and thus failing to work properly.

[0033] In some feasible embodiments, the plug-in assembly comprises the plug 10, the limiting block 11 and the connecting block 12, the gear 8 is provided with a through hole matched with the plug 10, the limiting block 11 is arranged on the side wall of the plug 10, the side wall of the through hole of the gear 8 is provided with a groove matched with the limiting block 11, the bottom of the plug 10 is provided with the connecting block 12, the connecting block 12 is fixedly connected with the top of the inner hexagonal wrench 13, the limiting block 11 can limit the relative rotation between the gear 8 and the inner hexagonal wrench 13, so that the inner hexagonal wrench 13 cannot be rotated when the gear 8 rotates, the plug 10 is plugged with the gear 8, and different sizes of the inner hexagonal wrench 13 can be replaced.

[0034] In use, a corresponding number of inner hexagonal wrenches 13 are inserted into the holes of the tension sleeve bolts, at this time, the inner hexagonal wrenches 13 are connected with the gear 8 through the plug-in assembly. Then the fixed plate 2 is sleeved with the inner gear ring 7 and the outer gear ring 9 on the shaft, and the lock catch 4 is locked, then the fixed plate 2 is moved towards the gear 8, so that all the gears 8 are clamped between the inner gear ring 7 and the outer gear ring 9, and are engaged with the inner gear ring 7 and the outer gear ring 9, the wrench 1 is rotated, since the gears 8 are limited by the inner hexagonal wrenches 13 through the fixed bolts at this time, they cannot revolve, the rotation of the outer gear ring 9 can drive all the gears 8 to rotate at the same time to loosen all the bolts, finally the dismounting tool is removed to dismount the tension sleeve.

[0035] Specifically, in the embodiment, the number of gears 8 determines the number of inner hexagonal wrenches 13, thereby determining the number of bolts that can be loosened at the same time.

[0036] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be combined appropriately to form other embodiments that those skilled in the art can understand. Thus, the embodiments of the present disclosure have been described in detail. In order to avoid obscuring the concept of the present disclosure, some details known in the art are not described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein according to the above description. The scope of the present disclosure is defined by the appended claims.
