Problems solved by technology

The previous monitoring methods mainly relied on the use of theodolite or various length measuring tools to regularly measure the height of the upper surface of the foundation or ballast bed (ie, the dynamic reference level of the component) from the supporting base surface (ie, the static reference level of the component). Most of the components such as the ballast bed are placed underground, and the elastic support components on the bridge are even in mid-air. It is very inconvenient to use existing tools to measure, requires a lot of manpower and material resources, and is prone to errors, especially in places where it is difficult to visually identify height changes. Under such circumstances, monitoring at any time cannot be realized, so there are certain potential safety hazards

Embodiment 1

[0020] Such as figure 1 , figure 2 As shown, the device for monitoring the height change of the elastic support member of the present invention includes a mark post 1 and a positioning support 2. The positioning support is provided with an observation hole 3 and a scale line 4 for marking the height, and the mark post 1 is provided with a benchmark for reading Line 6. The outer casing 7 of the shock absorber is preset in the subway track bed 9 elastically supported by the shock absorber 8, and the top surface of the casing 7 and the upper surface of the subway track bed 9 are on the same horizontal plane. The distance of the base surface will change with the change of the compression amount of the shock absorber 8, so the horizontal plane is a dynamic reference plane D, and the base surface that remains static constitutes the static reference plane J, at this time the subway track bed 9 is the elastic support members. Utilize the threaded part provided at the lower part of...

Embodiment 2

[0024] The difference between this embodiment and Embodiment 1 is that different color partitions are set on the positioning support 2 to replace the scale marks to mark the height. Such as image 3 As shown, on the surface of the positioning support 2 with the zero scale as the center, green, yellow, and red colors are set in turn to mark the working range of the ballast bed: the green color is the reasonable working area 4.1; the yellow color is the warning area 4.2; the red color is the failure area 4.3. The span ranges of the above-mentioned areas should be set reasonably after calculation according to the actual situation. When the reference line 6 points to different color areas, we can know the working status of the elastic support (shock absorber in the embodiment) in time according to the meaning represented by the color areas, so as to make maintenance adjustments in time to ensure safety. If it is yellow, observation should be strengthened, and when it is red, it s...

Embodiment 3

[0026] The device for monitoring the height change of the elastic support member according to the present invention can also be directly arranged on the member. Such as Figure 4 , Figure 5 As shown, a precision measurement platform 9 is an elastic support member, and a catheter 11 is preset in the equipment foundation. The measurement and positioning device of the monitoring device of the present invention includes a positioning support 2 and a zero point adjustment nut 10, and the lower end of the positioning support 2 is fixed on the top of the pipe 11 by interference fit. The benchmark post 1 runs through the positioning support 2 and the zero point adjustment nut 10 and is set in the conduit 11 , and its bottom end is in contact with the base surface of the supporting vibration isolator 8 . The benchmark post 1 is also provided with a scale line 4 for marking the height. At this time, the upper surface of the vibration-prone equipment foundation 9 is the dynamic datum ...

Abstract

The invention is related to method for monitoring height change of elastic support component momentarily, relevant equipment,elastic support component with monitoring device, and elastic support unit.Positioning device of following movement of dynamic reference plane is setup on elastic support component or elastic support unit. A signpost with one end being supported on static base surface setupis perpendicular to surface of the elastic support component. Displaying displacement of relative slip occurred between positioning device and signpost reflects change of relative distance between dynamic reference plane and static base surface of elastic support component so as to realize monitoring and measuring height change of elastic support component. Features are: simple and effective, saving a great lot of manpower, and material resources. The invention is applicable to manufacture, transportation, construction etc. areas.

Description

technical field [0001] The invention relates to a method and device for monitoring the height change of an object, in particular to a method capable of monitoring the height change of an elastic support member at any time, a corresponding device, an elastic support member with a monitoring device, and an elastic support device. Background technique [0002] In order to reduce the impact of vibration and noise, many large-scale equipment, precision equipment, track beds and other components have adopted elastic supports, and some sensitive buildings or sensitive rooms in buildings have adopted integral floating or partial elastic supports. Due to the dangers caused by natural failure or accidental damage, it is necessary to frequently confirm the height change of the above-mentioned elastic support members, understand and master the working conditions of the elastic support devices, and perform maintenance and replacement at any time according to the actual situation to ensure...
