Description

Technical Field

[0001] The invention relates to a measuring tool for multi-dimensionally measuring a large boiler steam soot blower combination, belonging to the technical field of thermal power plant maintenance. Background Art

[0002] Large boiler steam soot blower is a device used to remove coke deposits on the boiler heating surface. The structure of the short soot blower of the boiler consists of an actuator, a soot blowing gun head, and a soot blowing gun tube. When soot blowing, the gun head is inserted into the furnace at an angle of 90° for about 8 cm to blow soot. The soot blower will be deflected due to the effect of thermal stress after long-term operation. If the soot blower gun head is deflected, the soot blowing effect of the soot blower will be reduced or the heating surface will be damaged, thereby causing the heating surface to overheat or even burst the pipe and other hazards.

[0003] Therefore, when the unit is shut down, it is necessary to measure the multi-dimensional deformation of the main space of the short sootblower gun head, and manually extend the nozzle into the furnace after the unit is overhauled to measure the distance between the nozzle center and the water-cooled wall to ensure that the distance meets the design specifications and the angle of the nozzle and inner tube are perpendicular to the water-cooled wall, so that the sootblower can clean the boiler heating surface, improve heat transfer performance, adjust steam temperature, improve boiler efficiency, and ensure long-term safe and economical operation of the boiler.

[0004] At present, since the main space of the short sootblower gun head has multi-dimensional deformation, it is necessary to carry multiple detection tools into the boiler when detecting its deformation, which has certain operational risks, and multiple detection tools need to cooperate with each other for detection, which greatly prolongs the operation time and reduces work efficiency. Summary of the invention

[0005] In order to overcome the shortcomings of the above-mentioned prior art, the present invention designs a measuring tool for multi-dimensionally measuring a large boiler steam sootblower complex, which is easy to operate, can effectively improve work efficiency and reduce operational safety risks.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] A measuring tool for multi-dimensionally measuring a large boiler steam sootblower combination, comprising a ruler plate, wherein the upper portion of the ruler plate is provided with length scale markings in the length direction, and a hinged plate is hingedly connected to the end portion of the ruler plate, and an arc plate is integrally fixedly connected to the free end of the hinged plate, wherein the upper portion of the arc plate is provided with angle scale markings in the length direction, and when one side of the hinged plate is flush with the side surface of the ruler plate, the zero scale line of the arc plate is just aligned with the side surface of the ruler plate.

[0008] Furthermore, a handle is fixedly mounted on the arc-shaped plate.

[0009] Furthermore, the ruler plate is hinged to the hinge plate via a hinge pin.

[0010] Furthermore, the maximum scale of the ruler is 15 cm.

[0011] Furthermore, the maximum scale of the arc plate is 90°.

[0012] Furthermore, the length of the hinged plate is at least 8 cm.

[0013] Furthermore, the ruler plate is provided with a length unit mark.

[0014] Furthermore, a sleeve plate is fixedly connected to a side of the ruler plate away from the hinge plate, and an end of the arc plate away from the hinge plate is slidably sleeved in the sleeve plate.

[0015] Furthermore, the outer arc edge of the arc plate fits with the inner arc end surface of the sleeve plate.

[0016] Furthermore, the handle is a rectangular block structure.

[0017] Compared with the prior art, the present invention has the following characteristics and beneficial effects:

[0018] The present invention provides a ruler plate and an arc plate, and hinges the arc plate and the ruler plate through a hinge plate, that is, through the integrated design of a ruler and a protractor, thereby reducing the safety risk of carrying multiple tools to enter the boiler during previous operations. At the same time, the device can simultaneously measure the distance between the center of the nozzle and the water-cooled wall and the deflection angle of the sootblower. It is easy to operate, has high work efficiency, and ensures the cleanliness and aesthetics of the equipment on the maintenance site. The device is simple to manufacture, low in cost, and suitable for promotion and use. BRIEF DESCRIPTION OF THE DRAWINGS
