Description

Bolt disassembling tool

Technical Field

The utility model relates to the field of megawatt blade product demolding tools, in particular to a bolt disassembling tool.

Background

The embedded blade is characterized in that a bolt sleeve used for being connected with a host is required to be arranged at the root end of the blade in the production process of the embedded blade in advance, a flange tool is arranged at the root of the blade, the embedded bolt sleeve is fixed on a flange through a bolt, the bolt is detached after the blade is molded, and the blade is demoulded.

When the blade is demoulded, all bolts need to be detached from the flange firstly, and the technical problems that the production period of a product is prolonged, the production rhythm is disturbed, the labor cost is increased and the like can be caused if the bolts cannot be detached, and meanwhile, higher potential safety hazards and quality risks exist.

Because the production process of the blade is to introduce the epoxy resin through vacuum, the bolt sleeve needs to be sealed when being pre-embedded inside so as to avoid the situation that the connected bolts are solidified in the bolt sleeve because the resin enters the inside of the bolt sleeve. However, once the bolt is solidified in the bolt sleeve, the bolt sleeve cannot be taken out through manpower, and the bolt sleeve is easy to damage due to the external force if no proper tool is provided, so that the later-stage maintenance is required, and even the product is scrapped.

Aiming at the situation, no tool suitable for dismounting and mounting bolts in bolt sleeves during the production process of embedded blades exists at present.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problems that in the prior art, no tool for assembling and disassembling a bolt sleeve in a bolt curing process in the production process of an embedded blade is provided, so that the blade is long in disassembling and maintaining time, the bolt sleeve is easy to damage, and the product is scrapped.

In order to achieve the purpose, the utility model provides a bolt dismounting tool for dismounting a bolt sleeve and a bolt, which are arranged in a flange tool in the production process of an embedded blade.

The bolt dismounting tool comprises a plate-shaped body, a clamping portion arranged on the body and used for clamping and fixing a bolt (4), and a pushing piece arranged on the body, wherein the end portion of the pushing piece can be abutted to a flange tool sleeved on the bolt, so that the body drives the bolt clamped and fixed in the clamping portion to move in the direction away from the flange tool under the pushing action of the pushing piece, and the bolt sleeve is separated from the bolt sleeve arranged in the flange tool.

According to the bolt disassembling tool provided by the utility model, the body of the clamping part for clamping and fixing the bolt is arranged, and the flange tool with the end part capable of abutting against the bolt is arranged on the body, so that the bolt clamped and fixed in the clamping part is driven by the body to move towards the direction far away from the flange tool under the pushing action of the pushing piece, and the bolt sleeve arranged in the flange tool is separated. Therefore, the technical problems that the blade is long in disassembly and maintenance time, the bolt sleeve is easy to damage and the product scrapping condition is caused due to the fact that no tool is used for disassembling and assembling the bolt sleeve in the bolt sleeve during bolt curing in the embedded blade production process.

Preferably, the axial length of the clamping portion for clamping the bolt is not less than the length of the thread of the bolt arranged in the bolt sleeve.

Preferably, the clamping portion is a U-shaped groove which is arranged on the body and extends from one side edge to the opposite side edge.
