Detailed Description
As shown in figures 1-5, the portable cover plate for preventing the deep foundation pit from falling is made of stainless steel, is corrosion-resistant and has a long service life. The cover plate comprises a left cover plate 1 and a right cover plate 2, wherein the left cover plate 1 and the right cover plate 2 can be spliced into a circle with the diameter of 1.2 m. Be fixed with fossil fragments 3 at the back of left side apron 1, right side apron 2, fossil fragments 3 include first fossil fragments 3.1 and second fossil fragments 3.2, and first fossil fragments 3.1 is started from the centre of a circle, radially outwards stretches out along left side apron 1 or right side apron 2, and the length of first fossil fragments 3.1 is 0.75 m. The second keels 3.2 are distributed along the edge of the left cover plate 1 or the right cover plate 2 in a ring shape. When the combined type steel plate is used, when the left cover plate 1 and the right cover plate 2 are combined, the keels 3 on the left cover plate 1 and the right cover plate 2 are mutually nested and locked through the bolts.
The cover plate is fully heavy within 20kg, and in order to reduce the weight of the cover plate to the maximum extent, the through holes 6 are formed in the cover plate, so that the strength of the cover plate is ensured, the weight of the cover plate is reduced, and the cover plate is convenient for people to carry in the field.
As shown in fig. 2, in addition, an infrared biological detection device 4, a harmful gas detection device 10 and an alarm device 5 are detachably mounted in the center of the cover plate formed by the left cover plate 1 and the right cover plate 2, and both the infrared biological detection device 4 and the harmful gas detection device 10 are electrically connected with the alarm device 5.
The infrared biological detection device adopts a Search-I type infrared microwave detection device, and the principle of the infrared biological detection device mainly depends on an AND logic circuit structure, namely, the triggering alarm device needs to meet two conditions, namely, whether a heat source exists nearby by utilizing infrared detection or not and whether the heat source moves or not by utilizing microwave detection, and when the conditions are met, the alarm device is triggered.
The alarm device adopts an audible and visual alarm device with the model of YS-1509, and the audible and visual alarm device sends out a striking audible and visual prompt after the infrared biological detection is triggered to remind people of entering the device by mistake.
The harmful gas detection device adopts a four-in-one detection instrument of ERUN-PG51SA6 type, is internally provided with various sensors, and can detect oxygen, carbon monoxide and hydrogen sulfide (H) in a closed space or a container2S) and the concentration of the combustible gas.
Once the infrared biological detection device 4 finds that an idle person and the like are close to the foundation pit, the alarm device 5 can automatically give out harsh alarm sound to remind people of paying attention to danger. Moreover, the harmful gas detection device 10 can also prevent casualty accidents frequently occurring at present due to overhigh concentration of carbon dioxide or other harmful gases caused by the operation of constructors at the bottom of the foundation pit. When the alarm device needs to be detached, the alarm device can be detached at any time.
As shown in fig. 6, a rotating shaft 7 is rotatably mounted at one end of the first keel 3.1 extending out of the edge of the left cover plate 1 or the right cover plate 2, a roller assembly 8 is fixed on the rotating shaft 7, a through hole is drilled at one side of the rotating shaft 7, which is located outside the first keel 3.1, and an elastic assembly 9 is freely inserted into the through hole and limits the circumferential rotation of the rotating shaft 7. The elastic component 9 comprises a pull rod 9.1, the lower part of the pull rod 9.1 is inserted into a through hole of the rotating shaft 7, the pull rod 9.1 is positioned at the upper end of the rotating shaft 7 and is fixed with a limiting plate 9.2, the pull rod 9.1 at the upper part of the limiting plate 9.2 is sleeved with a spring 9.3, and the top end of the pull rod 9.1 freely passes through an ear plate 9.4 on the first keel 3.1.
As shown in fig. 6, in the normal state, the spring 9.3 presses on the limit plate 9.2, so that the pull rod 9.1 is inserted into the through hole of the rotating shaft 7, so that the rotating shaft 7 cannot rotate, and the state shown in fig. 7-8 is maintained. When needs overturn roller assembly 8, can upwards pull up pull rod 9.1, then rotate roller assembly 8, can rotate roller assembly 8 from first fossil fragments 3.1 outside to first fossil fragments 3.1 inside, or rotate roller assembly 8 from first fossil fragments 3.1 inside to first fossil fragments 3.1 outside. After the roller assembly 8 rotates 180 degrees, the pull rod 9.1 is loosened, and the pull rod 9.1 is inserted into the through hole of the rotating shaft 7 again for limiting.
The working principle and the process are as follows: when the cover plate is not used, the cover plate is disassembled into two parts to form a state shown in figures 4-5, so that the cover plate is convenient for workers to carry. When the apron is used to needs, the mode through the bolt will lap splice place together on the deep basal pit can, applicable in any operational environment, also can use on rugged and uneven road surface. In order to prevent non-workers from entering the construction site by mistake, as shown in fig. 2, the workers can install an infrared detection device 4 and an alarm device 5 at the center of the cover plate, and when the workers are close to and are detected by infrared rays, the alarm device sends out harsh alarm sound to play a role in reminding.
