Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment maintenance technology, specifically a device for removing equipment bushings. Background Technology

[0002] Metallurgical enterprises employ a wide variety of production equipment, including various mechanical devices and consumable spare parts, all of which require disassembly, maintenance, and replacement to ensure normal production and maintain the overall operation of the enterprise. Among these mechanical devices are many types of shafts, and shafts are fitted with bushings to protect them. However, for shafts and bushings with long maintenance cycles, prolonged lack of disassembly (or inadequate lubrication) can cause rust to "stick" the bushing and shaft together, making removal difficult during maintenance. Traditional disassembly methods include "heating the bushing" and "injecting rust remover," sometimes even involving destructive disassembly, which increases maintenance costs and is time-consuming and labor-intensive. Utility Model Content

[0003] To address the above deficiencies, this utility model provides a device for quickly removing equipment bushings, thereby solving the problem of rapid bushing removal.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A device for removing a bushing includes a disc base and a set of pull rods inclinedly installed on both sides of the upper end of the disc base. The disc base is provided with a clamping mechanism, and the upper end of the set of pull rods is connected to a removal mechanism.

[0006] The clamping mechanism includes a fixed base, a threaded rod, an adjusting block, a circular groove, an annular rotating frame, several connecting rods, and several L-shaped clamping claws. The fixed base is installed on the rear end of the disc base. The rear end of the threaded rod is movably inserted into the fixed base. The adjusting block is threaded onto the threaded rod. The circular groove is opened on the disc base. The bottom of the annular rotating frame is slidably installed on the circular groove. The rear ends of several connecting rods are respectively movably hinged to the disc base. Several L-shaped clamping claws are installed on the front ends of several connecting rods.

[0007] Furthermore, the dismantling mechanism includes a top plate, a jack, and a top seat. The top plate is fixedly installed on the upper end of a set of tie rods, the jack is installed at the center of the bottom of the top plate with its telescopic end facing vertically downward, and the top seat is installed on the telescopic end of the jack.

[0008] Furthermore, the bottom of the top seat has anti-slip texture.

[0009] Furthermore, the bottom of the adjusting block is hinged to the rear end of the annular rotating frame.

[0010] Furthermore, the annular rotating frame is movably hinged with several guide seats, and several connecting rods are respectively movably inserted into the corresponding guide seats.

[0011] Furthermore, a circular hole is provided at the center of the disc base.

[0012] This utility model provides a device for removing a bushing, which has the following advantages: a clamping mechanism is provided on the disc base, and rotating the threaded rod drives the annular rotating frame to rotate. Several L-shaped clamping claws first clamp the bottom of the bushing. Then, the jack of the removal mechanism drives the top seat to press the top of the inner shaft. By continuing to shake the jack handle, the bushing can be pushed out from the inner shaft, which meets the requirements for removing the bushing, reduces the cost of maintenance spare parts, and achieves the purpose of saving time and effort.

[0019] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1-5As shown: A device for removing a bushing includes a disc base 1 and a set of pull rods 2 inclinedly installed on both sides of the upper end of the disc base 1. The disc base 1 is provided with a clamping mechanism, and the upper end of the set of pull rods 2 is connected to a removal mechanism. The clamping mechanism includes a fixed seat 3, a threaded rod 4, an adjusting block 5, a circular groove 6, an annular rotating frame 7, several connecting rods 8, and several L-shaped clamping claws 9. The fixed seat 3 is installed on the rear end of the disc base 1. The rear end of the threaded rod 4 is movably inserted into the fixed seat 3. The adjusting block 5 is threaded onto the threaded rod 4. The circular groove 6 is opened on the disc base 1. The bottom of the annular rotating frame 7 is slidably installed on the circular groove 6. The rear ends of the several connecting rods 8 are distributed... The mechanism is hinged to the disc base 1, with several L-shaped clamping claws 9 mounted on the front ends of several connecting rods 8; the disassembly mechanism includes a top plate 10, a jack 11, and a top seat 12. The top plate 10 is fixedly mounted on the upper end of a set of pull rods 2, the jack 11 is mounted at the bottom center of the top plate 10 with its telescopic end facing vertically downward, and the top seat 12 is mounted on the telescopic end of the jack 11; the bottom of the top seat 12 has anti-slip texture 13; the bottom of the adjusting block 5 is hinged to the rear end of the annular rotating frame 7; several guide seats 14 are movably hinged inside the annular rotating frame 7, and several connecting rods 8 are respectively movably inserted into the corresponding guide seats 14; a circular hole 15 is opened at the center of the disc base 1.

[0020] The working principle of this implementation scheme is as follows: The annular rotating frame 7 has a double-layer structure, and the circular base 1 has a circular hole 15 at the center of the disc base 1, which facilitates the disc base 1 to pass through the inner shaft and bushing.

[0021] During clamping: The fixed seat 3 is installed on the rear end of the disc base 1. The rear end of the threaded rod 4 is movably inserted into the fixed seat 3 via a fastening bearing. The adjusting block 5 is threaded onto the threaded rod 4. The circular groove 6 is opened on the disc base 1. The bottom of the annular rotating frame 7 is slidably installed on the circular groove 6. The rear ends of several connecting rods 8 are respectively movably hinged to the disc base 1. Several L-shaped clamping claws 9 are installed on the front ends of several connecting rods 8. The bottom of the adjusting block 5 is hinged to the rear end of the annular rotating frame 7. Several guide seats 14 are movably hinged inside the annular rotating frame 7, and several connecting rods 8 are respectively movably inserted into the corresponding guide seats 14. Figure 2 and Figure 3 As shown, the user rotates the threaded rod 4 clockwise, causing the adjusting block 5 to move to the left, and causing the annular rotating frame 7 to rotate counterclockwise. The annular rotating frame 7, through several guide seats 14, causes several connecting rods 8 to deflect inward, so that several L-shaped clamping claws 9 at the front end first clamp the bottom of the bushing to be disassembled, as shown. Figure 4 As shown, this facilitates subsequent removal and disassembly of the bushing;

[0022] When removing the bushing: the top plate 10 is fixedly installed on the upper end of a set of tie rods 2, the jack 11 is installed at the center of the bottom of the top plate 10 with its telescopic end facing vertically downwards, and the top seat 12 is installed on the telescopic end of the jack 11. The bottom of the top seat 12 has anti-slip texture 13. Figure 5 As shown, the user first cranks the handle of jack 11, causing jack 11 to drive the top seat 12 to press against the top of the inner shaft. The anti-slip texture 13 can play an anti-slip role. Then, by continuing to crank the handle of jack 11, the bushing can be pushed out from the inner shaft, which meets the requirements for disassembling the bushing, reduces the cost of maintenance spare parts, and achieves the purpose of saving time and effort.

[0023] The above technical solution only embodies the preferred technical solution of this utility model. Any changes that may be made by those skilled in the art to certain parts of it embody the principle of this utility model and fall within the protection scope of this utility model.
