However, the saw blade lifting appliance is required to be used when the saw blade is replaced, the lifting appliance used on site is simple in structure, low in reliability and low in safety, the saw blade is not lifted stably when the saw blade is lifted, the saw blade is deflected or rocked, so that the saw blade is easy to unhook or the saw teeth of the saw blade injure people or key equipment is easy to knock, a scheme must be provided, the saw blade can be prevented from being rocked or deflected when the saw blade is lifted, in addition, the lifting hook is required to be replaceable, and the lifting appliance can have higher economic performance.

SUMMERY OF THE UTILITY MODEL

Therefore, an object of the present invention is to provide a special lifting device which can prevent the saw blade from shaking or deflecting when the saw blade is replaced, and can conveniently replace the fixed connecting member.

Further, the fixed connecting member is detachably connected in the connecting hole.

Further, the fixed connecting piece is in interference fit with the connecting hole.

Further, the hanger body is of a sheet structure.

Further, the fixed connecting piece is a screw or a pin.

Further, the hanger body is triangular.

Furthermore, the hanger body is provided with three connecting holes, and the connecting holes are distributed at three top corners of the hanger body.

Furthermore, a nut is further arranged at the connecting position of the fixed connecting piece and the connecting hole.

Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.

Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise. Furthermore, the terms "mounted," "connected," and "connected" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The embodiment of the utility model provides a special lifting device that hot sawing machine trades saw bit and uses, as shown in fig. 1 and fig. 2, including the hoist body 1 and hang and connect piece 2, hang the connecting piece 2 with the hoist body 1 is connected, the hoist body 1 has two or two above connecting holes 11, connecting hole 11 passes through fixed connector 3 and links to each other with the saw bit 5 of waiting to hoist, so that it forms the face contact to hang the body 1 and wait to hoist between the saw bit 5. The utility model fixedly connects the saw blade 5 on the side surface of the hanger body 1 through the fixed connecting piece 3 and the connecting hole 11, so that the saw blade 5 is tightly attached to the hanger body 1 to form surface contact, thereby limiting the shaking or deflection of the saw blade 5, and then the saw blade 5 is hoisted through the hoisting piece 5, and the process is more stable; additionally, the utility model discloses when well fixed connector 3 damaged, can follow and dismantle from connecting hole 11, replace to be new, can used repeatedly, make the hoist have higher economic performance.

In one aspect of the embodiment of the present invention, the fixing connector 3 is in interference fit with the connection hole 11. In order to fixedly connect the fixed connecting piece 3 in the connecting hole 11 by interference fit and further prevent the fixed connecting piece 3 from possibly falling off from the connecting hole 11, in a preferred embodiment, a nut 3 is further arranged at the connecting position of the fixed connecting piece 3 and the connecting hole 11, and by the design, even if the interference fit between the fixed connecting piece 3 and the connecting hole 11 fails due to abrasion, the saw blade 5 cannot be accidentally fallen off.

Preferably, the hanger body 1 is a sheet structure, further preferably, the hanger body 1 is triangular, the hanger body 1 is provided with three connecting holes 11, and the connecting holes 11 are distributed at three top corners of the hanger body 1. The design utilizes the stability of the triangle, realizes the aim of stable butt joint by using less fixed connecting pieces 3, simultaneously avoids the lifting appliance body 1 from covering the central hole of the saw blade 5 even if the lifting appliance body 1 of the sheet triangle is provided with the inner recesses at each side position of the triangle, is also favorable for reducing the manufacturing materials of the lifting appliance body 1 and saves the cost. Optionally, the fixed connector 3 is a screw or a pin.
