Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0028] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0029] Example

[0030] See also Figures 1 to 4As shown, this embodiment provides a clamping device 1 for locking a steel bar joint with a cone sleeve, comprising a first clamping clamp arm 11, a second clamping clamp arm 12 and a connecting plate 13. One end of the connecting plate 13 is rotatably connected to the first clamping clamp arm 11, and the other end is rotatably connected to the second clamping clamp arm 12, and the first clamping clamp arm 11 and the second clamping clamp arm 12 are arranged at intervals. The clamping device 1 for locking a steel bar joint with a cone sleeve also includes a first transmission gear 14 and a second transmission gear 15. The first transmission gear 14 is disposed between the first clamping clamp arm 11 and the second clamping clamp arm 12 and meshes with the first clamping clamp arm 11, and the rotating shaft of the first transmission gear 14 is rotatably connected to the connecting plate 13. The second transmission gear 15 is disposed between the first clamping clamp arm 11 and the second clamping clamp arm 12 and meshes with the second clamping clamp arm 12, and the rotating shaft of the second transmission gear 15 is rotatably connected to the connecting plate 13. The first transmission gear 14 and the second transmission gear 15 are meshed with each other. When the first clamping tongs arm 11 and the second clamping tongs arm 12 clamp the taper sleeve 4, the first transmission gear 14 and the second transmission gear 15 rotate synchronously.

[0031] The clamping device 1 for cone sleeve locking steel bar joints provided in the embodiment is configured to set a first transmission gear 14 and a second transmission gear 15 between the first clamping clamp arm 11 and the second clamping clamp arm 12, so that the first clamping clamp arm 11 rotates around the circumference of the first transmission gear 14, and the second clamping clamp arm 12 rotates around the circumference of the second transmission gear 15, thereby increasing the opening size of the clamping end 112 of the first clamping clamp arm 11 and the second clamping clamp arm 12, thereby increasing the opening stroke of the clamping device 1 for cone sleeve locking steel bar joints, thereby improving the use range of the clamping device 1 for cone sleeve locking steel bar joints and improving work efficiency.

[0032] The first clamp arm 11 includes a power end 111 and a clamp end 112. The power end 111 is subjected to force and drives the clamp end 112 to rotate under the action of the first transmission gear 14. The clamp end 112 is used to apply pressure to the cone sleeve 4 to connect the steel bar 3. The second clamp arm 12 is symmetrically arranged with the first clamp arm 11.

[0033] The connecting plate 13 is in the shape of a long strip and has a certain length to space the first clamping clamp arm 11 and the second clamping clamp arm 12 apart.

[0034] In one embodiment, the first clamping arm 11 includes a first tooth portion 113 , which is meshed with the first transmission gear 14 . The second clamping arm 12 includes a second tooth portion 121 , which is meshed with the second transmission gear 15 .

[0036] In one embodiment, the cross section of the first tooth portion 113 is arc-shaped, and the diameter of the first tooth portion 113 is greater than the diameter of the first transmission gear 14 .

[0037] In this embodiment, the diameter of the first tooth portion 113 is larger than the diameter of the first transmission gear 14. In this way, a smaller rotation angle of the first tooth portion 113 can drive the clamping end of the first clamping clamp arm 11 to move a longer distance, thereby increasing the opening stroke of the clamping device 1 used for cone sleeve locking of the steel bar joint.

[0038] The cross section of the second tooth portion 121 is also arc-shaped, and the diameter of the second tooth portion 121 is greater than the diameter of the second transmission gear 15. The diameter of the second tooth portion 121 is equal to the diameter of the first tooth portion 113.

The cross section of the outer circumference of the embracing portion 42 is wedge-shaped, and the inner circumference of the embracing portion 42 is used to connect the ends of the two steel bars 3. There are two pressing portions 41, which are respectively arranged at the positions of the outer circumference of the embracing portion 42 close to the ends, and the two pressing portions 41 move toward the middle of the embracing portion 42 and squeeze the embracing portion 42, so that the embracing portion 42 presses and connects the two steel bars 3.

In the process of the clamping end 112 of the first clamping clamp arm 11 driving the jaw member 16 to move, the jaw member 16 is fixed to the clamping end 112 so that the jaw member 16 and the pressing portion 41 of the cone sleeve 4 are closely matched, so as to improve the operating efficiency of the clamping device 1 for locking a steel bar joint with a cone sleeve.

[0046] The jaw member 16 further includes a fixing portion 165 , which is provided with a through hole 166 . The fixing portion 165 is connected to the fixing plate 17 by screws passing through the through hole 166 , so that the jaw member 16 is fixedly connected to the first clamping arm 11 .

[0047] In one embodiment, the second step portion 162 has a groove 164 . The groove 164 is disposed near the reinforcing bar 3 . The groove 164 is used to accommodate the embracing portion 42 of the cone sleeve 4 .

[0048] In one embodiment, the clamping device 1 for cone sleeve locking of a steel bar joint further includes a driving member 18, which connects the first clamping clamp arm 11 and the second clamping clamp arm 12, and is used to adjust the opening size of the first clamping clamp arm 11 and the second clamping clamp arm 12.

[0049] In this embodiment, the driving member 18 includes a cylinder 181 and a connecting rod 182. The connecting rod 182 is movably connected to the cylinder 181. The cylinder 181 is used to drive the connecting rod 182 to perform telescopic movement. One end of the connecting rod 182 is hinged to the first clamping clamp arm 11, and the other end is arranged in the cylinder 181. The cylinder 181 is hinged to the second clamping clamp arm 12. The cylinder 181 drives the connecting rod 182 to move to drive the first clamping clamp arm 11 and the second clamping clamp arm 12 to complete the clamping or opening action.

[0050] In other embodiments, the driving member 18 may also be driven by other power sources such as a motor, but this embodiment is not limited thereto.
