[0002] When gears and bearing parts are processed or assembled, hoisting operations are usually required. Currently, gears and bearing parts are mainly hoisted by a crane. When hoisted by the crane, a lifting tool is usually used to connect the gears and bearing parts to be hoisted, and the lifting tool in the prior art mainly adopts a combination of a sling and a hook. The sling is connected to the hook, and the hook is used to hook the gears and bearing parts to be hoisted to achieve hoisting.

DETAILED DESCRIPTION

[0024] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the protection scope of the present application.

[0025] In the description of the present application, it should be understood that the terms "upper", "middle", "outer", "inner", "lower" and the like indicate the orientation or positional relationship, only for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the indicated component or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0026] Please refer to Figures 1 to 4 The embodiment of the present application provides a gear and bearing part hoisting tool, which comprises a cross beam 01, a clamping device 02, a push-pull device 03, a linkage device 04; the clamping device 02 comprises a first clamping component 21 and a second clamping component 22, the first clamping component 21 and the second clamping component 22 are oppositely arranged at the two ends of the cross beam 01, and the upper ends of the first clamping component 21 and the second clamping component 22 are slidably connected with the cross beam 01; the push-pull device 03 comprises a first pushing component 31 and a second pushing component 32, the first pushing component 31 and the second pushing component 32 are symmetrically fixed on the cross beam 01 along the length direction of the cross beam 01, the installation direction of the first pushing component 31 is opposite to that of the second pushing component 32, the end of the first pushing component 31 is fixedly connected with the upper end of the first clamping component 21, and the end of the second pushing component 32 is fixedly connected with the upper end of the second clamping component 22; the linkage device 04 is rotationally arranged below the middle part of the cross beam 01, and the two ends of the linkage device 04 are rotationally connected with the upper parts of the first clamping component 21 and the second clamping component 22 respectively. When the first pushing component 31 and the second pushing component 32 are retracted, the first clamping component 21 and the second clamping component 22 can be pulled to retract towards the middle of the cross beam 01 respectively, so that the distance between the first clamping component 21 and the second clamping component 22 is reduced, thereby clamping and fixing the workpiece to be hoisted; when the first pushing component 31 and the second pushing component 32 are extended outward, the first clamping component 21 and the second clamping component 22 can be pushed to separate towards the two ends of the cross beam 01 respectively, so that the distance between the first clamping component 21 and the second clamping component 22 is increased, thereby releasing the hoisted workpiece; in the process of clamping or releasing the workpiece, the linkage device 04 can assist the first pushing component 31 and the second pushing component 32 to retract towards the middle or separate outward at the same time, which not only can stably clamp and fix the workpiece to be hoisted, but also can avoid the workpiece from falling off during hoisting, thereby improving the safety of hoisting.

[0027] In an embodiment, the linkage 04 comprises a first connecting rod 41, an intermediate connecting rod 42, and a second connecting rod 43. The intermediate connecting rod 42 is rotatably connected to the bottom of the crossbeam 01 at a middle position. The first connecting rod 41 and the second connecting rod 43 are arranged on the two sides of the intermediate connecting rod 42. The two ends of the first connecting rod 41 are rotatably connected to the first clamping component 21 and one end of the intermediate connecting rod 42 respectively. The two ends of the second connecting rod 43 are rotatably connected to the second clamping component 22 and the other end of the intermediate connecting rod 42 respectively. In this scheme, the first pushing component 31 and the second pushing component 32 can work simultaneously or individually. When the first pushing component 31 and the second pushing component 32 work simultaneously, the first pushing component 31 exerts a pushing force on the first connecting rod 41 when the first pushing component 31 and the second pushing component 32 are retracted simultaneously, so that the first connecting rod 41 pushes the intermediate connecting rod 42 to rotate. The other end of the intermediate connecting rod 42 is connected to the second connecting rod 43, so that the intermediate connecting rod 42 provides a pulling force on the second connecting rod 43 when the intermediate connecting rod 42 rotates, so that the second connecting rod 43 can better retract the second clamping component 22. At the same time, the second pushing component 32 also exerts a pushing force on the second connecting rod 43, so that the second connecting rod 43 pushes the intermediate connecting rod 42 to rotate. The other end of the intermediate connecting rod 42 is connected to the first connecting rod 41, so that the intermediate connecting rod 42 provides a pulling force on the first connecting rod 41 when the intermediate connecting rod 42 rotates, so that the first connecting rod 41 can better retract the first clamping component 21. By using this design, the first pushing component 31 and the second pushing component 32 can provide auxiliary forces for each other, so that the workpiece can be better clamped and fixed by the first clamping component 21 and the second clamping component 22, and the stress on the workpiece during clamping is more balanced, ensuring stable clamping. When releasing the workpiece, since the weight of the gear and bearing parts to be lifted is relatively large, the same principle can be used to separate the first clamping component 21 and the second clamping component 22, so that the stress on the workpiece during the release process is balanced, and the phenomenon of sudden separation on one side does not occur. When the first pushing component 31 and the second pushing component 32 work individually, i.e., only the first pushing component 31 works or only the second pushing component 32 works, the first pushing component 31 or the second pushing component 32 can still provide retraction or separation power for the other, so as to realize clamping and fixing of the workpiece.

[0028] In an embodiment, the first clamping component 21 and the second clamping component 22 have the same structure. The first clamping component 21 comprises a sliding seat 211, a support column 212, and a clamping mechanism 213. The sliding seat 211 is slidably arranged below the crossbeam 01. The support column 212 is longitudinally arranged below the sliding seat 211. The clamping mechanism 213 is fixed to the lower end of the support column 212.

[0029] Specifically, the clamping mechanism 213 includes a rib plate 2131, a limiting plate 2132, and a support plate 2133. The rib plate 2131 is fixed at the lower end of the support column 212. The limiting plate 2132 is detachably arranged at both ends of the rib plate 2131 close to the middle connecting rod 42, so that a certain spacing is formed between the two limiting plates 2132. The limiting plate 2132 is in an arc-shaped structure, and the two limiting plates 2132 are distributed in an arc shape. When clamping the workpiece, the limiting plate 2132 can form a balanced centripetal force on the workpiece, so as to achieve stable clamping of the workpiece and ensure that the center of gravity of the workpiece does not deviate during clamping. The support plate 2133 is correspondingly fixed at the lower end of the limiting plate 2132, and can be used to support the workpiece.

[0030] A lining plate 2134 is arranged on the side of the limiting plate 2132 close to the middle connecting rod 42 and the upper surface of the support plate 2133. The lining plate 2134 can be made of rubber, which can prevent the workpiece edge from being abraded and generating burrs, and can increase the friction between the workpiece and the lining plate 2134 after being extruded during clamping, thereby ensuring the stability of clamping.

[0031] In an embodiment, the first pushing component 31 and the second pushing component 32 have the same structure. The first pushing component 31 includes a telescopic assembly 311 and a connecting seat 312. The telescopic assembly 311 is fixedly arranged above the cross beam 01. The lower end of the connecting seat 312 is fixedly connected with the sliding seat 211, and the upper end of the connecting seat 312 is fixedly connected with the extending end of the telescopic assembly 311. The telescopic assembly 311 can be any one of an electric telescopic rod, a pneumatic telescopic cylinder, and a hydraulic oil cylinder.

[0032] In an embodiment, a control handle 05 is further arranged. The control handle 05 is electrically connected with the telescopic assembly 311 installed on the first pushing component 31 and the second pushing component 32 through wires. The telescopic assembly 311 can be controlled through the control handle 05.

[0033] A protective cover 11 is arranged below the middle part of the cross beam 01. The protective cover 11 completely contains the middle connecting rod 42, and the protective cover 11 is open near the two ends of the first clamping component 21 and the second clamping component 22. A lifting ring 12 is arranged at the top of the middle part of the cross beam 01, which can be connected with a crane during hoisting.

[0034] The above disclosure is only the preferred embodiment of the present application, and of course cannot limit the scope of the rights of the present application. Those skilled in the art can understand that all or part of the above-mentioned embodiments can be implemented, and equivalent changes made according to the claims of the present application still fall within the scope of the present application.
