AI Technical Summary
During equipment maintenance operations, special wrenches of different models are required, which leads to high maintenance costs and is difficult to operate in limited space.
An emergency wrench was designed, including a ring, nut, handle and bolt. By uniformly welding three nuts on the outside of the ring, the three bolts were screwed into the nut and passed through the ring, the handle was welded vertically to the outer wall of the ring. A screwable device is formed to operate in a limited space.
The emergency wrench is simple to assemble and operates easily, avoiding the purchase of special wrenches, saving expenses, and can easily perform maintenance operations in limited space, reducing construction costs.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of equipment maintenance operations, and in particular provides an emergency wrench for maintenance operations. Background Art
[0002] During equipment maintenance, special wrenches are generally used as bolt tightening tools. The disadvantages of using special wrenches are: first, it is necessary to purchase different types of wrenches suitable for maintenance in advance, which increases the maintenance cost; second, for bolts in confined spaces, sometimes special wrenches have no operating space and are not easy to tighten during maintenance. Utility Model Content
[0003] The utility model aims to provide an emergency wrench for maintenance work, which solves the problem of high maintenance cost.
[0004] The utility model surrounds the equipment maintenance bolts with the ring of the emergency wrench, then screws three bolts at the same time, so that the three bolt heads are pressed tightly against the outsides of the maintenance bolts, and then the maintenance bolts are screwed by operating the handle.
[0005] The utility model emergency wrench comprises a ring 1, a nut 2, a handle 3, and a bolt 4, which are used in combination. The three nuts 2 are uniformly welded to the outside of the ring 1; the three bolts 4 are respectively screwed into the three nuts 2 and pass through the ring 1; the handle 3 is vertically welded to the outer wall of the ring 1 (see FIG. Figure 1 , Figure 2 ).
[0006] Among them, the ring 1 is processed from a round tube with a diameter of 50mm and a length of 40mm; the nut 2 has a diameter of 14mm; the handle 3 is processed from a round steel with a diameter of 20mm and a length of 200mm; the bolt 4 has a diameter of 14mm and a length of 60mm.
[0007] When in use, surround the equipment maintenance bolt 5 with the ring 1 of the emergency wrench, then tighten the three bolts 4 at the same time, so that the heads of the three bolts 4 are pressed against the outside of the maintenance bolt 5, and then operate the handle 3 to tighten the maintenance bolt 5 (see Figure 3 , Figure 4 ).
[0008] The utility model has the advantages of simple assembly and convenient operation, which not only avoids the need to purchase a special wrench and saves expenses, but also allows for easy maintenance and operation in a limited space and reduces construction costs. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 This is the front view of the emergency wrench.
[0010] Figure 2 This is a top view of the emergency wrench.
[0011] Figure 3 Use the Home view for the emergency wrench.
[0012] Figure 4 Use the top view for the emergency wrench.
[0013] In the figure, there are a ring 1, a nut 2, a handle 3, a bolt 4, and an inspection bolt 5. DETAILED DESCRIPTION
[0014] Figure 1-Figure 4 This is a specific implementation of the utility model. The utility model is further described below in conjunction with the accompanying drawings.
[0015] The utility model emergency wrench comprises a ring 1, nuts 2, a handle 3 and bolts 4, which are used in combination. Three nuts 2 are evenly welded to the outside of the ring 1; three bolts 4 are respectively screwed into the three nuts 2 and pass through the ring 1; and the handle 3 is vertically welded to the outer wall of the ring 1.
[0016] When in use, the ring 1 of the emergency wrench is placed around the equipment maintenance bolt 5, and then the three bolts 4 are screwed at the same time so that the heads of the three bolts 4 are pressed tightly against the outside of the maintenance bolt 5, and then the handle 3 is operated to screw the maintenance bolt 5.
[0017] When overhauling the rolling mill equipment, an emergency wrench is used as the maintenance bolt tightening tool, which not only avoids the purchase of special wrenches and saves expenses, but also allows easy maintenance operations in a confined space, which is convenient, fast and effective. The emergency wrench is used in combination, and the three nuts are evenly welded to the outside of the ring; the three bolts are respectively screwed into the three nuts and passed through the ring; the handle is vertically welded to the outer wall of the ring. When in use, the ring of the emergency wrench surrounds the equipment maintenance bolts, and then the three bolts are screwed at the same time, so that the three bolt heads are pressed against the outside of the maintenance bolts, and then the handle is operated to screw the maintenance bolts. The emergency wrench is simple to assemble and easy to operate, which not only avoids the purchase of special wrenches and saves expenses, but also allows easy maintenance operations in a confined space, reducing construction costs.
