Automatic regulatable guard bar on surface of power station boiler

Abstract

The invention discloses an automatic regulatable guard bar on the surface of a power station boiler. A placing tank is arranged on the upper surface of a bottom plate, a U-shaped bottom plate is arranged on the right side of the bottom plate, the U-shaped baffle plate is fixed to the right side of the bottom plate through a screw, an electric push rod is arranged in the placing tank, the left sideof the electric push rod is fixedly connected to the inner wall of the left side of the placing tank, the right side of the electric push rod is fixedly connected to the baffle plate, a movable blockis movably arranged on the left side of the baffle plate on the electric push plate in a sleeving manner, the baffle plate is fixedly connected to the movable block through the spring, limiting devices are fixedly arranged at the bottoms of the movable block and the baffle plate, and the top of the movable block is fixed and welded to the bottom of a vertical pipefitting. In an actual using process, the baffle plate can be pushed by the electric push rod to move back and forth in the placing tank, so that the vertical pipefitting and a movable rod move back and forth, and therefore, the protecting area of the vertical pipefitting and the movable rod can be changed. The movable rod can be adjusted in height in the vertical pipefitting, so that the protecting height can be adjusted, and theautomatic regulatable guard bar is relatively wide in applicability.

Description

technical field [0001] The invention relates to the technical field of automatic adjustable guardrails, in particular to an automatic adjustable guardrail on the surface of a power plant boiler. Background technique [0002] The so-called power plant boiler, in general, is the boiler used by the power plant to generate electricity. Generally, the capacity is relatively large. The current main unit is 600MW, and the more advanced one is the ultra-supercritical boiler with a capacity of up to 1000MW. There are two main types of power plant boilers: pulverized coal boilers and circulating fluidized bed boilers. These two types of boilers are the main types currently used in power plants. There are ladders around the power plant boilers, and protective railings are provided on the outside of the ladders to prevent people from falling from the ladders. However, it still has the following disadvantages in actual use: [0003] 1. The guardrails in the prior art are all fixedly we...

Problems solved by technology

[0003] 1. The guardrails in the prior art are all fixedly welded on the outer surface of the ladder, so the protective area of ​​the guardrail is fixed. When multiple people need to pass through at the same time (for example, when carrying things), the fixed guardrail is obviously more in the way , at this time it is necessary to increase the protective area of ​​the guardrail, which cannot be achieved in the prior art;

[0004] 2. Since the existing guardrails are fixed and welded, when a person accidentally bumps into the guardrail, it will generate a great impact and cause greater damage;
