[0020] In view of this, according to an embodiment of this application, a hook-type disassembly tool is provided, such as... Figure 1 , Figure 4 As shown, the device includes a shaft 1, a claw portion, and a transmission structure. The claw portion includes multiple hooking elements 2, which are arranged circumferentially on the circumferential surface of the shaft 1. Each hooking element 2 includes a hook 21. The root end of the hook 21 is hinged to the shaft 1 in a direction perpendicular to the length of the shaft 1, and the tip of the hook 21 extends in a direction away from the shaft 1. The transmission structure is arranged on the shaft 1 and the hooking elements 2, and is used to drive the hooking elements 2 to rotate around the hinge point.

[0021] Furthermore, in one embodiment, such as Figure 1As shown, three hooks 2 are provided; the three hooks 2 are evenly arranged on the circumferential side of the shaft body 1.

[0022] Furthermore, in one embodiment, such as Figure 1 , Figure 2 , Figure 4 As shown, the hook 2 also includes a connecting block 22; the root end of the hook 21 is fixedly connected to the connecting block 22, and one end of the connecting block 22 is hinged to the shaft 1 through a first connecting rod 11 provided on the shaft 1.

[0023] Specifically, the claw tip is designed to fit the disassembly port of the device to be disassembled; one end of the connecting block 22 and the first connecting rod 11 are both provided with corresponding connecting holes, and the connecting block 22 and the first connecting rod 11 are hinged together by inserting a pin into the connecting hole. The transmission structure can control multiple hooks 2 to rotate simultaneously toward the shaft 1 to retract or rotate simultaneously toward the shaft 1 to open. In actual operation, first, the hooks 2 are fully retracted, and the claws are brought close to the device to be disassembled; then, the transmission structure is operated to open the hooks 2, and the claw tips of multiple hooks 21 are respectively inserted into multiple disassembly ports 61 of the device to be disassembled; the transmission structure is continued to be operated to open the hooks 2 until they completely abut against the multiple disassembly ports 61 in the cross-sectional direction of the device to be disassembled; finally, by applying a pulling force or a torsional force, the device to be disassembled is separated from the mounting base. Figure 6 As shown, for the monitoring device 6 installed on the idler roller 7, since the monitoring device 6 is provided with three disassembly clips 61, in a specific embodiment, three hooks 2 are provided.

[0024] Preferably, in a specific embodiment, the shaft 1 is integrally formed from high-quality carbon structural steel No. 45, and after forging and tempering (quenching and high-temperature tempering), its tensile strength is ≥600MPa, possessing good structural strength and wear resistance. The hook part 2 is forged from Cr12MoV die steel and then precision machined, and after quenching and low-temperature tempering treatment, its hardness reaches HRC58-62.

[0025] Preferably, in specific embodiments, such as Figure 1As shown, the transmission structure includes a sleeve 3 and a pushing component; the sleeve 3 is sleeved outside the shaft 1 and located on the side of the first connecting rod 11 away from the hook 21; guide limiting components are provided on the connecting block 22 and the sleeve 3 to limit and guide the opening or closing of the hook 21; the pushing component is provided on the shaft 1 to allow the shaft 1 to undergo axial displacement relative to the sleeve 3, so that the hook 21 opens in a direction away from the shaft 1 or closes in a direction close to the shaft 1.

[0026] Specifically, the inner surface of the sleeve 3 and the outer surface of the shaft 1 are in close contact and can slide relative to each other axially. When the sleeve 3 approaches the first connecting rod 11, the hook 21 retracts; when the sleeve 3 moves away from the first connecting rod 11, the hook 21 opens.

[0027] Preferably, in specific embodiments, such as Figure 1 , Figure 3 , Figure 4 As shown, the guide limiting member includes a second connecting rod 31 disposed on the peripheral side of the sleeve 3; a protrusion 23 is disposed on the side of the connecting block 22 away from the hook 21; the protrusion 23 is hinged to the sleeve 3 via the second connecting rod 31 in a direction perpendicular to the length of the sleeve 3.

[0028] Specifically, the connecting block 22 is hinged to both the shaft 1 and the sleeve 3. When the connecting block 22 rotates around the hinge point with the first connecting rod 11, the hook 21 opens or closes. The hinge point between the connecting block 22 and the second connecting rod 31 controls the movement direction of the hook 21 to remain stable and limits the opening degree of the hook 21.

[0029] Preferably, in a specific embodiment, the sleeve 3 is made of 45 steel, and the two ends of the second connecting rod 31 are respectively connected to the sleeve 2 and the protrusion 23 by pin hinges.
