Technical Field

[0001] This utility model relates to the technical field of bushing installation and disassembly tools, specifically a bushing puller that is compatible with both pulling and tapping installation functions. Background Technology

[0002] When installing the bushing on an axial flow fan, external installation and disassembly tools are required.

[0003] For example, the Chinese authorized patent, with announcement number CN203636737U, is titled "(An Installation Tool for Fixing the Rotor of a Large Axial Flow Fan)," and includes: an installation tool body, characterized in that: the installation tool body consists of a long strip-shaped body and a rectangular adjusting plate connected to one end of the body; bolt holes are opened on the body; an adjusting device is provided on the adjusting plate; and a top PTFE plate is provided at the end of the adjusting device. Its advantages are: simple structure, good stability, adjustability, and the ability to effectively reduce the amplitude of the rotor's back-and-forth and left-and-right sway during hoisting, allowing the rotor and stator blades to smoothly and stably connect.

[0004] However, existing bushing components come in a variety of specifications, and the installation and disassembly of bushing components of various specifications involves the cumbersome process of changing the end of the disassembly and installation tools. Therefore, they do not meet the existing requirements. To address this, we propose a bushing puller that is compatible with both pull-out and hammer-out installation functions. Utility Model Content

[0005] The purpose of this utility model is to provide a bushing puller that is compatible with both pulling and hammering installation functions, so as to solve the problem mentioned in the background art that the existing bushing components have diverse specifications, and that it is cumbersome to change the end of the disassembly and disassembly tools when installing and disassembling bushing components of various specifications.

[0007] Also includes:

[0008] The thread is installed on the outer wall of the lower end face of the connecting rod body. There are two threads, and a cut end is provided between the two threads. There are three cut ends. The three cut ends and the threads are integrally formed with the connecting rod body.

[0009] Adjustable jaws are installed on the outside of the three cut ends. There are three adjustable jaws, and the interior of each of the three adjustable jaws is provided with an inner groove. The three inner grooves are integrally formed with the adjustable jaws.

[0010] Preferably, a latching block is provided above the three adjustable claws, the latching block slides vertically with the connecting rod body, and a first bolt block is provided on the upper end surface of the latching block, the first bolt block and the connecting rod body are connected by a threaded rotation.

[0011] Preferably, the lower end face of the latching block is provided with a groove, and the groove is integrally formed with the latching block. The uppermost adjustable latch of the three adjustable claws is installed inside the groove for latching.

[0012] Preferably, the three adjustable jaws are provided with bushing covers on their exterior, the bushing covers are in contact with the front end face of the adjustable jaws, and a second bolt block is provided below the three adjustable jaws.

[0013] Preferably, a second bolt block is provided below the three adjustable claws.

[0014] Preferably, a grip handle is provided at the upper end of the main rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model, through the setting of a first bolt block, a snap-fit ​​block, a groove, adjustable claws, an inner groove, and a second bolt block, allows for the adjustment of the length of the adjustable claws. After the length of the contact ends of the three adjustable claws is adjusted, the snap-fit ​​block limits and fixes the adjusted positions of the three adjustable claws. Then, the first bolt block and the second bolt block are rotated and fixed with the threads, thereby firmly fixing the positions of the three adjustable claws. The installation and removal of the bushing cover can be achieved through the three adjustable claws. When the connecting rod is installed above the three adjustable claws, the bushing cover can be removed, and when the connecting rod is installed below the three adjustable claws, the bushing cover can be installed. This effectively avoids the problem of cumbersome replacement of disassembly and installation tool ends when using existing bushing components with diverse specifications and multiple specifications of bushing components for installation and removal.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1

[0024] Please see Figure 1-4 The present invention provides an embodiment of a bushing puller that is compatible with both pulling and hammering installation functions, comprising: a main rod 100, a connecting rod 200 provided at the lower end of the main rod 100, the connecting rod 200 being connected to the lower end of the main rod 100 via a connecting block 300, and one end of both the main rod 100 and the connecting rod 200 being rotatably fixed to the connecting block 300;

[0025] Also includes:

[0026] The thread 2001 is installed on the outer wall of the lower end face of the connecting rod body 200. There are two threads 2001, and a cut end 2002 is provided between the two threads 2001. There are three cut ends 2002. All three cut ends 2002 and threads 2001 are integrally formed with the connecting rod body 200.

[0027] Adjustable claws 204 are installed on the outside of the three cut ends 2002. There are three adjustable claws 204. The interior of each of the three adjustable claws 204 is provided with an inner groove 20401. The three inner grooves 20401 are integrally formed with the adjustable claws 204.

[0028] The three adjustable claws 204 can be extended in length at the cut end 2002 via the inner groove 20401. By adjusting the length of the contact ends of the three adjustable claws 204, they can be used with different specifications of bushing covers 400 to achieve installation or disassembly.

[0029] Example 2

[0030] Please see Figure 2 and Figure 3A latching block 202 is provided above the three adjustable claws 204. The latching block 202 slides vertically with the connecting rod body 200. A first bolt block 201 is provided on the upper end face of the latching block 202. The first bolt block 201 is rotatably connected to the connecting rod body 200 through a thread 2001. A groove 203 is provided inside the lower end face of the latching block 202, and the groove 203 is integrally formed with the latching block 202. The uppermost adjustable claw 204 of the three adjustable claws 204 is installed inside the groove 203 for latching.

[0031] By using the latching block 202 set above the three adjustable claws 204, and the first bolt block 201 and the second bolt block 205 used in conjunction, the latching block 202 limits and fixes the adjusted position of the three adjustable claws 204. Then, the first bolt block 201 and the second bolt block 205 are rotated and fixed with the thread 2001, so that the three adjustable claws 204 can be firmly fixed in position.

[0032] Please see Figure 1 The three adjustable claws 204 are provided with bushing covers 400 on the outside, and the bushing covers 400 are in contact with the front end face of the adjustable claws 204. The three adjustable claws 204 are provided with a second bolt block 205 below them, and the main rod body 100 is provided with a grip handle 101 at the upper end.

[0033] Working principle: When using this puller, the length of the adjustable claws 204 can be adjusted first. After the length of one end of the three adjustable claws 204 is adjusted, the latch block 202 limits and fixes the adjusted position of the three adjustable claws 204. Then, the first bolt block 201 and the second bolt block 205 are rotated and fixed with the thread 2001, thereby firmly fixing the position of the three adjustable claws 204. The installation and removal of the bushing cover 400 can be achieved through the three adjustable claws 204. When the connecting rod 200 is installed above the three adjustable claws 204, the bushing cover 400 can be removed. When the connecting rod 200 is installed below the three adjustable claws 204, the bushing cover 400 can be installed.
