Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of acetylene cylinder switches, and particularly relates to an inner four-corner convenient wrench for an acetylene cylinder switch. Background Art
[0002] A pulse soot blower is a device used to remove the ash deposited on the tube walls of economizers, superheaters, reheaters, etc. in the vertical flue of a large boiler. The pulse soot blower releases pressure through acetylene deflagration to shock the ash on the tube walls, which is an important means for power plant boilers to ensure the cleanliness of the heating surface, improve boiler efficiency, and prevent ash fouling and coking on the boiler heating surface.
[0003] The switch of the acetylene cylinder is a quadrilateral cylinder. Usually, an adjustable wrench is used to rotate the quadrilateral main body to open and close the acetylene cylinder. Due to frequent use of the adjustable wrench to open and close, the quadrilateral cylinder is worn and the thread slips, resulting in damage to the acetylene cylinder switch and ineffective pulse soot blowing work.
[0004] The acetylene supplier provides a special tool. Due to the insufficient strength of the aluminum material, the inner hole often slips and the handle is easily bent and deformed. Content of the Utility Model
[0005] The main purpose of the utility model is to provide an inner four-corner convenient wrench for an acetylene cylinder switch, which is used to solve the problems that the existing tools for acetylene switches are prone to cause wear and thread slipping of the acetylene switch and the tool slips and deforms.
[0006] To achieve the above purpose, the utility model provides an inner four-corner convenient wrench for an acetylene cylinder switch. The acetylene cylinder switch includes a quadrilateral convex column with a preset size. The convenient wrench includes:
[0007] A chuck. One end of the chuck is internally provided with a reinforcing sleeve, and the other end of the chuck extends a preset length away from the reinforcing sleeve to form a connecting portion. The reinforcing sleeve is sleeved outside the quadrilateral convex column and matches the preset size.
[0008] A crank. The crank includes a vertical rod section, an arc rod section, and a horizontal rod section connected end to end. One end of the vertical rod section far from the arc rod section is fixedly connected to the connecting portion, and a reinforcing member is provided between the vertical rod section and the horizontal rod section. The horizontal rod section is used to receive an external force to drive the quadrilateral convex column to rotate through the arc rod section, the vertical rod section, and the chuck.
[0009] As a further improvement of the utility model, a clamping cavity is provided inside the chuck. The external shape of the reinforcing sleeve is the same as the shape of the clamping cavity, and the reinforcing sleeve is in interference fit with the clamping cavity. A connecting cavity is provided inside the reinforcing sleeve. The connecting cavity is in clearance fit with the quadrilateral convex column.
[0010] As a further improvement of the utility model, the outer diameter of the vertical rod section decreases from the connection with the connecting portion towards the connection with the arc rod section.
[0011] As a further improvement of the present utility model, the reinforcing member includes a reinforcing rod; both ends of the reinforcing rod are fixedly connected to the outer wall of the connection part adjacent to the end of the vertical rod and the outer wall of the cross-bar section far from the arc-bar section respectively, so as to form a triangular support in the enclosed area of the reinforcing rod, the vertical rod end, the arc-bar section and the cross-bar section.
[0012] The beneficial effects of the present utility model are embodied in:
[0013] By sleeving the reinforcing sleeve on the quadrilateral convex column on the acetylene cylinder, the strength of the chuck is enhanced, and internal wear and deformation of the chuck are avoided; and under the action of the reinforcing rod, the stress concentrated on the arc-bar section of the rotating cross-bar section is dispersed, preventing the arc-bar section from deforming due to stress concentration.
