Description

Technical Field

[0001] The utility model relates to the technical field of retracting guns of boiler soot blowers, and particularly relates to a portable retracting gun electric crank for a boiler soot blower. Background Technique

[0002] A steam soot blower is a device used to remove the ash deposited on the heating surface of a power plant boiler; boiler steam soot blowing is an important means to ensure the cleanliness of the heating surface of a power plant boiler, improve the boiler efficiency, and prevent ash fouling and coking on the heating surface of the boiler. Because of frequent use, it often fails. Especially for the furnace soot blower with a long stroke (13.3 m) and a high furnace temperature, when a failure occurs, the steam soot blowing gun barrel must be immediately withdrawn to prevent the soot blowing gun barrel from being bent, deformed or broken and falling to damage the water-cooled wall.

[0003] The original manual crank equipped by the manufacturer is in a "Z" shape, which is connected to the convex quadrilateral column at the tail of the boiler soot blower. By rotating the manual crank, the steam soot blowing gun barrel is withdrawn. Due to the limited operating space and the long length of the soot blowing gun barrel, it takes 2 - 3 hours to retract the gun using the manual crank and 4 - 5 people take turns to squat down to operate. It is time-consuming and laborious, and the soot blowing gun barrel often burns red and bends (the power and steam must be cut off during the gun retraction process, and there is no cooling medium for the soot blowing gun), resulting in scrapping. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a portable retracting gun electric crank for a boiler soot blower, which is used to solve the problem that the existing steam soot blowing gun barrel is withdrawn by manually rotating a manual crank. Due to the limited operating space and long operating time, it is time-consuming and laborious, and the soot blowing gun barrel often burns red and bends and is scrapped.

[0005] To achieve the above purpose, the utility model provides a portable retracting gun electric crank for a boiler soot blower. The boiler soot blower includes a steam soot blowing gun barrel located inside the boiler and a quadrilateral convex column with a preset size located outside the boiler and connected to the steam soot blowing gun barrel; the gun-retracting electric crank includes:

[0006] A connecting head, one end of the connecting head is sleeved outside the quadrilateral convex column and matches the preset size, and the other end of the connecting head extends a preset length in a direction away from the quadrilateral convex column to form a connecting portion; a socket portion is provided on the connecting portion;

[0007] An adapter, one end of the adapter is detachably connected to the socket portion, and the other end of the adapter is provided with a conversion cavity with a preset size;

[0008] A driving part, the output end of the driving part is detachably connected to the conversion cavity, and the driving part drives the adapter to rotate under the action of an external force, so as to drive the quadrilateral convex column to rotate through the connecting head.

[0009] As a further improvement of the present utility model, a connection cavity with a preset size is provided inside the connection head; the connection cavity is sleeved with the quadrilateral convex column, and there is a clearance fit between the inner wall of the connection cavity and the outer wall of the quadrilateral convex column.

[0010] As a further improvement of the present utility model, the length of the connection cavity in the radial direction is greater than the length of the quadrilateral convex column in the radial direction.

[0011] As a further improvement of the present utility model, the connection part is a solid end provided at one end of the connection head away from the quadrilateral convex column; the socket part is a polygonal convex head.

[0012] As a further improvement of the present utility model, a clamping cavity with a preset size is provided inside the adapter; the clamping cavity is clamped with the socket part, and there is a clearance fit between the inside of the clamping cavity and the outer wall of the socket part.

[0013] The beneficial effects of the present utility model are reflected in:

[0014] By providing a connection head, it can be quickly connected to the quadrilateral convex column at the tail of the steam soot blower barrel. Under the connection of the adapter, the connection head and the driving part can be quickly connected. By driving the rotation of the driving part, the adapter and the connection head are driven to rotate, so that the convex quadrilateral column at the tail of the steam soot blower rotates, and the steam soot blower barrel is withdrawn. In the present utility model, the traditional manual gun withdrawal operation is changed, which can be used repeatedly, saves labor, prevents the steam soot blower gun from being bent or broken due to staying in the furnace for a long time, and saves production costs.
