Referring to fig. 1-4, the present embodiment provides a coupling removal tool, comprising:

a grabbing plate 110, wherein an opening is formed on one side of the grabbing plate 110, and the width of the bottom of the opening of the grabbing plate 110 is smaller than the width of the coupler 200;

a top extension plate 120, wherein the top extension plate 120 is connected to the grabbing plate 110, and the length between the top extension plate 120 and the grabbing plate 110 is greater than the length of the coupling 200;

the jacking piece 130, one end of the jacking piece 130 is arranged on the jacking plate 120, and the jacking piece 130 is arranged between the jacking plate 120 and the grabbing plate 110.

When the coupler 200 needs to be disassembled, the opening of the grabbing plate 110 is sleeved on the mounting shaft 300 of the coupler 200, so that the coupler 200 is positioned between the grabbing plate 110 and the jacking plate 120, meanwhile, the jacking piece 130 is propped against the axis of the mounting shaft 300 of the coupler 200, the jacking plate 120 is jacked up by the jacking piece 130 to enable the jacking plate 120 to pull the grabbing plate 110, the width of the bottom of the opening of the grabbing plate 110 is smaller than that of the coupler 200, and the grabbing plate 110 can drive the coupler 200 to drop from the mounting shaft 300 in the process of pulling the grabbing plate 110 by the jacking plate 120, so that the coupler is disassembled. The coupling 200 can be removed without damage, and the coupling 200 can be removed by the tool regardless of the length of the coupling 200. The disassembly efficiency of the coupler is improved.

The jacking plates 120 and the grabbing plates 110 with different types can be manufactured according to the actual size of the motor for installing the shaft 300 coupler, the coupler 200 can be removed by using the jacking members 130 with different specifications, and the coupler can be used for the non-destructive removal of bearings. When the bearing is dismounted, the opening of the grabbing plate 110 is sleeved on the mounting shaft 300 of the bearing, so that the bearing is positioned between the grabbing plate 110 and the jacking plate 120, the other end of the jacking piece 130 is propped against the mounting shaft 300, the jacking piece 130 jacks up the jacking plate 120, and the grabbing plate is driven to pull the bearing in the outwards moving process of the jacking plate 120, so that the bearing is dismounted from the mounting shaft 300.

Referring to fig. 2 and 4, in some embodiments, the bottom of the opening of the plate is rounded. By setting the opening bottom of the grabbing plate 110 to be circular arc-shaped, the opening bottom of the grabbing plate 110 is more attached to the mounting shaft 300, so that the coupling 200 can be more firmly grabbed, and the coupling 200 can be removed more smoothly. The size of the circular arc shape of the opening bottom of the corresponding grip plate 110 may be set according to the size of the mounting shaft 300 of the coupling 200.

Referring to fig. 2 and 4, in some embodiments, the opening of the grabbing plate 110 is flared. The opening of grabbing and lifting is in a horn shape, namely the width of the bottom of the opening of the grabbing plate 110 is smaller than the width of the opening and closing part, and the opening of the grabbing plate 110 is set to be in a horn shape, so that the opening and closing part of the opening of the grabbing plate 110 can be quickly read and sleeved into the mounting shaft 300, the opening of the grabbing plate 110 is conveniently sleeved on the mounting shaft 300, and the quick dismantling of the coupler 200 is realized.

Referring to fig. 1, in some embodiments, the top extension plate 120 is detachably connected to the grabbing plate 110 through a plurality of screw rods 140. The lead screw 140 is a rod with external threads on the surface, the jacking plate 120 and the grabbing plate 110 are detachably connected through the lead screw 140, different distances between the jacking plate 120 and the grabbing plate 110 can be set by adjusting the positions of the jacking plate 120 and the grabbing plate 110 on the lead screw 140, disassembly of the shaft coupler 200 with different lengths can be achieved, the jacking plate 120 and the grabbing plate 110 can be connected by selecting the lead screw with the corresponding length according to the length of the shaft coupler 200140, and disassembly of shaft couplers with different lengths can be achieved. As shown in fig. 2-5, mounting holes 150 are formed on the top extending plate 120 and the grabbing plate 110, the top extending plate 120 and the grabbing plate 110 are mounted on the screw rod 140 by arranging nuts 160 on two sides of each mounting hole on the top extending plate 120 and the grabbing plate 110, positions of the top extending plate and the grabbing plate on the screw rod are adjusted by the mounting holes of the top extending plate and the grabbing plate, and after the positions are adjusted in place, the top extending plate and the grabbing plate are fixed on two sides of each mounting hole by the nuts, so that the top extending plate 120 and the grabbing plate 110 are detachably mounted on the screw rod 140 through the mounting holes 150 by matching of the nuts 160. In other embodiments, other connectors may be used to connect the top extension plate 120 to the gripping plate 110, such as a string.

In some embodiments, the jacking members 130 are jacks. The jack is a small and light lifting device that uses a rigid lifting member 130 as a working device to lift a weight through a small stroke of a top bracket or bottom jaw. The jack is mainly used for departments such as factories and mines, transportation and the like to repair vehicles and work such as other lifting and supporting. The structure is light, firm, flexible and reliable, and can be carried and operated by one person. The jack is divided into a mechanical jack, a hydraulic jack and the like, and the principles are different. The jack can be divided into three types according to structural characteristics, namely a rack jack, a screw jack and a hydraulic (oil pressure) jack. The hydraulic jack can be divided into a separation type jack, a horizontal jack, a claw type jack, a synchronous jack, an oil pressure jack, an electric jack and the like according to other modes. Among the jacks commonly used are screw jacks, hydraulic jacks, electric jacks and the like. In principle, the most basic principle on which hydraulic transmission is based is pascal's law, that is, the pressure is uniform throughout the liquid. Thus, in a balanced system, the pressure exerted on the smaller piston is smaller and the pressure exerted on the larger piston is also larger, thus being able to keep the liquid stationary. So that different pressures at different ends can be obtained through liquid transmission, and the purpose of transformation can be achieved. The common hydraulic jack uses this principle to achieve force transfer. The screw jack pulls the handle in a reciprocating manner, the pulling claw pushes the ratchet wheel to rotate in a clearance manner, the small bevel gear drives the large bevel gear to enable the lifting screw to rotate, so that the lifting sleeve is lifted or lowered to achieve the lifting tension function, but the lifting jack is not as simple as the hydraulic jack. In other embodiments, the jack 130 may be an electric push rod, a hydraulic cylinder, or the like. An electric putter is an electric drive device that converts the rotational motion of an electric motor into linear reciprocating motion of a putter. Can be used in various simple or complex process flows as an execution machine to realize remote control, centralized control or automatic control. The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). The device has simple structure and reliable operation. When it is used to realize reciprocating motion, it can eliminate speed reducer, and has no transmission clearance and smooth motion, so that it can be widely used in hydraulic systems of various machines. The output force of the hydraulic cylinder is in direct proportion to the effective area of the piston and the pressure difference between two sides of the effective area of the piston; the hydraulic cylinder basically consists of a cylinder barrel, a cylinder cover, a piston rod, a sealing device, a buffer device and an exhaust device. The buffer device and the exhaust device are necessary for other devices depending on the specific application. In other embodiments, the jacking member 130 may also be a bolt, for example, by arranging a connecting hole in the middle of the jacking plate 120, and arranging an internal thread in the connecting hole, the connecting hole of the jacking plate 120 is in threaded connection with the bolt, when the coupling 200 needs to be disassembled, the bolt is rotated by using a tool, such as a wrench, and the wrench and a nut of the bolt are integrated together, so that one end of a screw rod of the bolt is screwed into the mounting shaft, one end of the screw rod of the bolt pushes against the mounting shaft 300 to push the jacking plate 120, and then the grabbing plate 110 is pulled to pull the coupling 200 on the mounting shaft 300, so that the coupling 200 is separated from the mounting shaft 300, and the coupling 200 is disassembled from the mounting shaft 300.

In some embodiments, the gripping plate 110 and the top extension plate 120 are steel plates. The steel plate is a flat plate steel material which is formed by pouring molten steel, cooling and pressing. By setting the grabbing plate 110 and the pushing plate 120 as steel plates, the steel plates have good rigidity, so that the grabbing plate 110 and the pushing plate 120 are not easy to deform and damage when the pushing plate 120 is pushed up by the pushing member 130 and the grabbing plate 110 grabs the coupling 200.

In some embodiments, the gripping plate 110 and the top extension plate 120 are square. When the grabbing plate 110 and the top extending plate 120 are square, the four corners of the grabbing plate 110 and the top extending plate 120 are provided with mounting holes 150, and the grabbing plate 110 and the top extending plate 120 can be connected through four screw rods 140 and 16 nuts 160. In other embodiments, the grabbing plate 110 and the top extension plate 120 may be configured in a circular shape, a triangular shape, or the like.

In some embodiments, the bottom of the opening of the grip plate 110 is the center of the grip plate 110. By setting the bottom of the opening of the grabbing plate 110 as the center of the grabbing plate 110, the stress point of the grabbing plate 110 to the coupling 200 can be located at the center of the grabbing plate 110, so that the grabbing plate 110 is not easy to fall off from the mounting shaft 300 during the process of removing the coupling 200.

Finally, it should be noted that, although the foregoing embodiments have been described in the text and the accompanying drawings of the present application, the scope of the patent protection of the present application is not limited thereby. All technical schemes generated by replacing or modifying equivalent structures or equivalent flows based on the essential idea of the application and by utilizing the contents recorded in the text and the drawings of the application, and the technical schemes of the embodiments are directly or indirectly implemented in other related technical fields, and the like, are included in the patent protection scope of the application.
