Description

Technical Field

[0001] This utility model relates to the field of gas turbine assembly tools, specifically to a hook-type bolt wrench. Background Technology

[0002] A gas turbine is an internal combustion engine that uses a continuously flowing gas as the working fluid to drive a high-speed rotating impeller, converting the energy of fuel into useful work. It is a type of rotary impeller-type thermal engine. Its internal and external structures are typically secured to the rotor or stator using fasteners. In areas with limited space, hook bolts can be used for fixing, facilitating assembly and improving efficiency. For example, Chinese Utility Model Patent Publication No. CN211715508U proposes a hook bolt for a gas turbine compressor rotor. When assembling the hook bolt, a spring plate needs to be fixed to the base plate. Applying an upward force to the spring plate causes the hook-shaped part of the spring plate to engage with the protrusion on the base plate. However, manual assembly of hook bolts is inefficient, and using other tools to hammer them poses a risk of damaging parts. Therefore, a hook bolt installation tool needs to be designed to improve assembly efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to propose a hook bolt wrench that reduces the assembly difficulty of hook bolts, improves assembly efficiency, saves labor costs in the assembly process, and reduces damage to parts caused by assembling hook bolts.

[0004] The hook-type bolt wrench of this utility model includes a first handle and a second handle, which are longitudinally hinged together. The hinge point causes the first handle to form a first force-applying part and a first clamping part, and the second handle to form a second force-applying part and a second clamping part. The first force-applying part is located below the second force-applying part, and the first clamping part is located above the second clamping part. The first force-applying part includes a first handle, and the second force-applying part includes a second handle. Both the first handle and the second handle are obliquely upward curved. The first clamping part includes a clamping block with a U-shaped opening. The second clamping part includes a base, and the clamping block and the base are arranged vertically opposite each other.

[0005] Preferably, the first handle body and the second handle body are hinged together by a bolt with a pin, and the bolt is provided with a nut.

[0006] Preferably, both the first handle and the second handle are perpendicular to the bolt.

[0007] Preferably, gaskets are provided on the bottom of the clamping block and the upper part of the base support to prevent damage to the base plate and hook bolts caused by the first clamping part and the second clamping part.

[0008] Preferably, the gasket is an elastomer sheet.

[0009] Preferably, the two ends of the U-shaped opening of the clamping block extend downward to form protrusions, and the bottom of the protrusions is provided with a pad. The protrusions make it easier to position and apply force to the clamping block.

[0010] Preferably, both the outer surfaces of the first and second handles are provided with anti-slip textures.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] Utilizing the lever principle, upward and downward forces are applied to the first and second force-applying parts, respectively. The first clamping part holds the edge of the base plate, and the bottom support of the second clamping part applies upward force to the hook bolt, causing it to snap onto the base plate. This method is convenient and labor-saving, reduces the assembly difficulty of the hook bolt, improves assembly efficiency, saves labor costs in the assembly process, and reduces damage to parts caused by assembling the hook bolt.

[0019] The present invention will now be described clearly and completely with reference to the accompanying drawings.

[0020] It should be noted that in this article, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another for ease of expression, and do not represent a sequential relationship.

[0021] Example 1

[0022] like Figure 1As shown, the hook-type bolt wrench of this utility model includes a first handle 1 and a second handle 2. The first handle 1 and the second handle 2 are longitudinally hinged together, and the hinge point causes the first handle 1 to form a first force-applying part 3 and a first clamping part 4, and causes the second handle 2 to form a second force-applying part 5 and a second clamping part 6. The first force-applying part 3 is located below the second force-applying part 5, and the first clamping part 4 is located above the second clamping part 6. The first force-applying part 3 includes a first handle 7, and the second force-applying part 5 includes a second handle 8. Both the first handle 7 and the second handle 8 are obliquely curved upwards. The first clamping part 4 includes a clamping block 9, such as... Figure 4 As shown, the clamping block 9 is provided with a U-shaped opening 10, and the second clamping part 6 includes a base 11. The clamping block 9 and the base 11 are arranged opposite each other vertically.

[0023] like Figure 3 , Figure 4 As shown, the first handle 1 and the second handle 2 are hinged together by a bolt 12 with a pin, and a nut 13 is provided on the bolt 12. The first handle 7 and the second handle 8 are both perpendicular to the bolt 12.

[0024] like Figure 2 As shown, the bottom of the clamping block 9 and the upper part of the base 11 are both provided with pads 14, and the pads 14 are elastic sheets.

[0025] The work process is as follows: Figure 5 As shown, the screw of the hook bolt 16 is passed through the assembly hole of the base plate 17. The first handle 7 and the second handle 8 are held to open the first force application part 3 and the second force application part 5, thereby opening the first clamping part 4 and the second clamping part 6. The bottom support 11 of the second clamping part 6 abuts against the spring plate of the head of the hook bolt 16. At the same time, the screw of the hook bolt 16 is placed in the U-shaped opening 10, and the clamping block 9 abuts against the base plate 17. The first force application part 3 and the second force application part 5 apply force to each other, so that the bottom support 11 applies force to the spring plate of the hook bolt 16, and the hook part of the spring plate is engaged with the protrusion of the base plate 17, thus realizing the assembly of the hook bolt 16 and the base plate 17.

[0026] Example 2

[0027] Based on Example 1, such as Figure 2 As shown, the two ends of the U-shaped opening 10 of the clamping block 9 extend downward to form protrusions 15, and the bottom of the protrusions 15 is provided with a pad 14. The outer surfaces of the first handle 7 and the second handle 8 are both provided with anti-slip texture.
