Description

Technical Field

[0001] The utility model relates to a device for monitoring the internal space of a steel trestle board, belonging to the field of environmental monitoring equipment. Background Art

[0002] Steel trestle board is an important construction equipment and is widely used in construction sites to provide passages for personnel and vehicles and a stacking platform for materials or equipment. Steel trestle board is a relatively closed structure, which is not easy to generate airflow and form a dry environment. Excessive humidity in the internal air will greatly accelerate the corrosion rate of the steel structure. When it reaches a certain level, the mechanical properties of the steel trestle board will decrease or even be damaged, which may cause serious production safety accidents.

[0003] At present, after the used steel trestle boards are delivered to the station, maintenance personnel conduct visual inspections, mainly to observe whether the main force-bearing structure of the steel trestle boards is broken or bent, whether the overall structure is intact, and whether there are dents or damage on the surface. However, the steel trestle boards are subjected to pressure in the middle during use. After long-term use, cracks that are difficult to observe with the naked eye are inevitable, which leads to an increase in internal air humidity, accelerates the corrosion of the steel trestle boards, and reduces the structural strength. Therefore, it is necessary to conduct inspections on the internal conditions of the steel trestle boards, such as whether the air humidity is qualified. The existing detection method is to open the side panels of the steel trestle boards for detection, which has low detection efficiency. Moreover, after the steel trestle boards are opened, the air inside the steel trestle will circulate with the external air, affecting the accuracy of the detection of the internal air humidity of the steel trestle.

The temperature and humidity sensor is connected to the display screen signal, and the display screen can display the data collected by the temperature and humidity sensor.

[0009] The regulating structure comprises a desiccant placing box and a desiccant. The desiccant placing box is connected to the second end of the shell of the monitoring structure. The desiccant is placed in the desiccant placing box.

[0010] Furthermore, the projections of the shell and the desiccant placement box along the axis of the threaded rod are located within a circle with the core diameter of the threaded rod as its diameter.

[0021] The following is a further detailed description of a steel trestle board internal space monitoring device provided by the utility model in combination with the accompanying drawings and specific embodiments. Combined with the following description, the advantages and features of the utility model will become clearer. It should be noted that the accompanying drawings are all in a very simplified form and are not in precise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model.

[0022] like Figure 1 As shown, the present embodiment provides a device for monitoring the internal space of a steel trestle board. The steel trestle board 1 generally includes an upper panel, a lower panel, a frame structure, and an internal support structure. The internal support structure is arranged in the frame structure. For example, an I-beam, a channel steel, or an arched beam plate structure may be used to support the upper panel and the lower panel. The upper panel, the lower panel, and the frame structure enclose a relatively closed space structure. If the air humidity in the space structure is high, the corrosion of the steel trestle board 1 will be accelerated, affecting the safety of the steel trestle board 1. The monitoring device 10 provided in the present embodiment is used to continuously monitor the temperature and humidity of the internal space of the steel trestle board 1.

[0023] The monitoring device 10 comprises a connecting structure 11, a monitoring structure 12, an adjusting structure 13 and a display screen 14. The connecting structure 11, the monitoring structure 12 and the adjusting structure 13 are connected in sequence, and the display screen 14 is arranged at one end of the connecting structure 11 away from the monitoring structure 12.

[0024] The connection structure 11 includes a threaded rod 111 and a bolt head 112 . One side of the bolt head 112 is connected to the first end of the threaded rod 111 , and the other side of the bolt head 112 is provided with a display screen 14 .

[0025] The second end of the threaded rod 111 is connected to a monitoring structure 12, and the monitoring structure 12 includes a housing 121, a temperature and humidity sensor 122, a battery box 123 and a battery. The battery box 123 is arranged in the housing 121 for placing batteries. The temperature and humidity sensor 122 is arranged in the housing 121 for measuring the temperature and humidity of the environment. The temperature and humidity sensor 122 is connected to the display screen 14 by signal, and signal transmission can be achieved through the signal line 124 or by wireless transmission. When the signal line 124 is used for signal transmission, a signal line through hole is provided in the threaded rod, and a sealant is used to fill the gap around the signal line, so that the display can display temperature and humidity. The battery supplies power to the display screen 14 and the temperature and humidity sensor 122. The first end of the housing 121 is welded and fixed to the second end of the threaded rod 111.

[0026] The regulating structure 13 includes a desiccant placement box and a desiccant. The desiccant placement box is connected to the housing 121 of the monitoring structure 12 . The desiccant placement box is filled with a desiccant to regulate the air humidity in the inner space of the steel trestle board 1 .

[0027] The monitoring device 1 is specifically applied as follows: a nut 2 is welded on the frame structure of the steel trestle board 1, a hole is opened on the frame structure at the position corresponding to the screw hole of the nut 2, and the adjustment structure 13 and the monitoring structure 12 are passed through the screw hole of the nut 2 in sequence, so that the threaded rod 111 is threadedly connected with the nut 2, and a sealing gasket 3 can be set on the threaded rod 111 between the bolt head 112 and the frame structure of the steel trestle board 1 to isolate the internal space of the steel trestle board 1 from the external space, and prevent the external humid air from entering the internal space of the steel trestle board 1. The desiccant absorbs the water vapor in the internal space of the steel trestle board, reduces the air humidity in the internal space, and prevents the steel plate of the steel trestle board from rusting. The temperature and humidity sensor 122 measures the temperature and humidity of the internal space, and the display shows the temperature and humidity. When the humidity in the internal space of the steel trestle board exceeds the preset value, it may be that the desiccant has failed, and it is necessary to separate the threaded rod 111 from the nut 2 and replace the desiccant in the desiccant placement box. Of course, it is also possible to directly drill a thread hole on the frame structure, and match the external thread of the threaded rod with the internal thread of the thread hole to achieve a threaded connection between the threaded rod and the frame structure, in which case no nut is required.

[0028] Since the monitoring structure 12 and the adjustment structure 13 need to be inserted into the screw hole of the nut 2, the projections of the shell 121 and the desiccant box along the axial direction of the threaded rod 111 are located within a circle with the core diameter of the threaded rod 111 as the diameter, that is, the distance between any two points on the cross section of the shell 121 and the desiccant box is smaller than the core diameter of the threaded rod 111.

[0029] In a specific embodiment, a monitoring structure 12 is provided on each of the left and right sides of the frame structure of the steel trestle board 1, and a rope ring 15 is provided at one end of the desiccant placement box of the monitoring structure 12. The rope rings 15 of the two monitoring structures 12 are arranged opposite to each other, and an annular rope 16 passes through the rope ring 15. Pulling the annular rope 16 can make the annular rope 16 slide in the rope ring 15, and the annular rope 16 is used to provide a moving path for the endoscope lens. The endoscope is used to observe the internal structure of the steel trestle board 1, and the endoscope includes an endoscope lens, an endoscope information harness, and an endoscope analysis and display device. When in use, the threaded rod 111 of the monitoring device 10 is separated from the nut 2, and the threaded rod 111, the monitoring structure 12, and the adjustment structure 13 are taken out, the endoscope lens and the annular rope 16 are fixed by a clamp, and the annular rope 16 is pulled so that the annular rope 16 pulls the endoscope lens to move inside the two steel trestle boards 1 to collect images or videos of the internal structure of the steel trestle boards 1. The endoscope analysis and display device analyzes the collected images or videos to determine whether the steel trestle boards 1 meet the safety requirements.

[0030] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
