Hydraulic nut dismounting tool

Abstract

The utility model discloses a hydraulic nut disassembling tool which comprises a base, a supporting shaft and a hanging shaft are fixedly installed on the same sides of the two ends of the base respectively, a copper sleeve is fixedly installed at the end, away from the base, of the supporting shaft, and a safety plate is installed at the end, away from the base, of the hanging shaft in a sliding mode. When the nut is pushed out, part of the nut falls on the copper sleeve, the device provides supporting force for the part away from the shaft end until all the nut falls on the copper sleeve, and at the moment, the safety plate slides to enable the safety plate to fall down to serve as a baffle to prevent the nut from falling off from the copper sleeve. Afterwards, the device can be moved through a crane so as to move the disassembled nut, and manpower is saved.

Description

Hydraulic nut removal tool Technical Field

[0001] This utility model relates to the field of auxiliary tooling, and in particular to a hydraulic nut disassembly tooling. Background Technology

[0002] Because ships are large, the parts used on them are also much larger than those on general equipment. Therefore, it is difficult to operate them manually when disassembling and assembling them. For example, when removing the hydraulic nut installed on the stern shaft, it is very heavy and difficult to lift manually after it is removed from the shaft. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hydraulic nut disassembly tool, which solves the current pain points in this field.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] The hydraulic nut disassembly fixture includes a base, on which a support shaft and a lifting shaft are fixedly installed on the same side at both ends. A copper sleeve is fixedly installed on the end of the support shaft away from the base, and a safety plate is slidably installed on the end of the lifting shaft away from the base.

[0006] To further explain, the safety plate has a groove in the middle, and a fixing bolt is installed at the end of the hanging shaft. The fixing bolt passes through the groove, and tightening the fixing bolt can fix the safety plate.

[0007] To further explain, a lifting lug is fixedly installed in the middle of the lifting shaft.

[0008] In summary, the advantages of this utility model compared to the prior art are as follows: the device can be lifted and moved to the side of the nut to be disassembled and set on the nut disassembly and movement path. When the nut is pushed out, part of it falls onto the copper sleeve. The device provides support for the part that leaves the shaft end until all the nut falls onto the copper sleeve. At this time, the sliding safety plate falls down as a baffle to prevent the nut from falling off the copper sleeve. Then, the device can be moved by a crane to move the disassembled nut, saving manpower. Attached Figure Description

[0009] The above and other objects, features, and advantages of the present invention will become readily apparent from the following detailed description of exemplary embodiments, taken in conjunction with the accompanying drawings. Several embodiments of the present invention are illustrated in the drawings by way of example and not limitation, in which:

[0011] Explanation of reference numerals in the attached diagram: 1. Base; 2. Support shaft; 3. Copper sleeve; 4. Hanging shaft; 5. Safety plate; 6. Slide groove; 7. Fixing bolt; 8. Lifting lug. Detailed Implementation

[0012] The utility model will be further described in detail below with reference to the accompanying drawings.

[0013] The hydraulic nut disassembly fixture includes a base 1. A support shaft 2 and a lifting shaft 4 are fixedly installed on the same side at both ends of the base 1. A copper sleeve 3 is fixedly installed at the end of the support shaft 2 away from the base 1. A safety plate 5 is provided at the end of the lifting shaft 4 away from the base 1. A sliding groove 6 is provided in the middle of the safety plate 5. A fixing bolt 7 is installed at the end of the lifting shaft 4. The fixing bolt 7 passes through the sliding groove 6. Tightening the fixing bolt 7 can fix the safety plate 5. Loosening the fixing bolt 7 can move the safety plate 5.

[0014] A lifting lug 8 is fixedly installed in the middle of the lifting shaft 4, through which the device can be lifted.

[0015] When disassembling the hydraulic nut on the stern shaft, the device is lifted by a crane, bringing the copper sleeve 3 close to the shaft end. The nut is then moved towards the shaft end, causing the portion that is off the shaft end to fall onto the copper sleeve 3, thus receiving the removed nut. When the nut has completely fallen onto the copper sleeve 3, the safety plate 5 is moved downward to prevent the nut from coming off the copper sleeve 3. Using this tooling to assist in the effective positioning of the nut can save manpower for lifting.

[0016] The above description is merely an exemplary embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. The scope of protection of the present utility model is determined by the appended claims.
