Detailed Description

The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present utility model, based on the embodiments of the present utility model.

As shown in fig. 1, 2 and 3, the monitoring device for the deep foundation pit comprises a mounting table 1, and a monitoring alarm mechanism 2 is arranged on the mounting table 1. Similar to the prior art, the bottom of mount table 1 also circumference is provided with a plurality of staple bolt poles 5 to be equipped with band 15 on the outer wall of a plurality of staple bolt poles 5, can tighten a plurality of staple bolt poles 5 in the stand 16 that waits to detect through band 15. Different, in order to realize that monitoring devices are applicable to the detection of stand 16 of different diameters required, the design of this disclosure sets up a plurality of slides 3 on the bottom surface of mount table 1, and each slide 3 all extends along radial, still slides on each slide 3 and is connected with mount pad 4, and a plurality of staple bolt poles 5 of above-mentioned one-to-one connect on a plurality of mount pads 4. It will be appreciated that when several hoop poles 5 are on the same circumference, the rounded structure formed between the several hoop poles 5 has a cohesive diameter that depends on the distance between the opposing hoop poles 5.

For example, when the clasping diameter of the monitoring device needs to be adjusted to adapt to the stand columns 16 with different diameters, a worker can slide each mounting seat 4 to adjust the radial position of the hoop rod 5, and then can adjust the clasping diameter of the stand column 16 to be detected, so that the applicability of the monitoring device is improved.

Further, a plurality of connecting holes 6 are formed in the end face of the slideway 3, and the connecting holes 6 are uniformly distributed along the extending direction of the slideway 3. In addition, the mounting seat 4 is also connected with a fastening bolt 7 in a threaded manner. Obviously, the relative position of the mounting seat 4 in the slideway 3 can be fixed by screwing the fastening bolt 7 into the connecting hole 6, so that the radial position of the hoop rod 5 is fixed.

In some embodiments, the support rod 8 is disposed on the inner side of the mounting seat 4 located on the hoop rod 5, where the inner side is the side closer to the center of the mounting table 1 or the upright 16, and the opposite side away from the center of the mounting table 1 or the upright 16 is the outer side. When mount table 1 installs in stand 16, a plurality of bracing pieces 8 can support at the top surface of stand 16, so the condition that the whole mount table 1 is difficult for appearing subsideing by oneself for stand 16, for example when the banding power of band 15 appears under the condition of certain inefficacy because of certain factors, and then monitor alarm mechanism 2 is difficult for appearing erroneous judgement to the subsidence of stand 16, and monitoring devices's reliability of use is higher. Preferably, the bottom of the supporting rod 8 is provided with a supporting piece 9 extending towards the inner side, and the bottom surface of the supporting piece 9 can be attached to the top surface of the upright post 16, so that the supporting effect of the supporting rod 8 on the mounting table 1 is achieved, and the supporting piece 9 has a larger supporting area and can have a better supporting effect.

More specifically, the monitoring alarm mechanism 2 comprises a monitoring tube 10 connected between a stand column 16 and a support column 17, and a trigger ball 11 is movably connected in the monitoring tube 10. Wherein, both ends of the monitoring pipe 10 are respectively hinged to the upright 16 and the supporting column 17, so that when the upright 16 is settled, the monitoring pipe 10 will be in a state of being inclined to one side of the upright 16, and then the trigger ball 11 in the pipe will fall to one side of the upright 16. Correspondingly, a pressure sensor 12 is arranged on one side, close to the mounting table 1, of the monitoring tube 10, and when the trigger ball 11 falls to one side of the upright post 16, the trigger ball 11 can collide with and trigger the pressure sensor 12, and then the pressure sensor 12 gives an alarm through a control system. The control system is in the prior art, so that a detailed description is omitted in this embodiment. Briefly, the control system may include a controller and an alarm, with the pressure sensor 12, the controller and the alarm being electrically connected.

In some embodiments, the monitoring and alarm mechanism 2 may further include a connecting rod 14 horizontally disposed on a side wall of the support column 17, the connecting rod 14 being configured in an L-shape with its vertical section fixedly connected to the support column 17 and its bent section having its end portion projecting into the monitoring tube 10. Further, it is also configured that when the monitor pipe 10 is in the horizontal state, the trigger ball 11 is located at the center of the monitor pipe 10, and the end of the above-described connecting rod 14 is opposite to the trigger ball 11, and the trigger ball 11 is made to abut on the side wall of the connecting rod 14 on the side facing the support column 17. Therefore, when the monitoring tube 10 is not inclined to the upright post 16, the connecting rod 14 can limit the trigger ball 11, so that the situation that the trigger ball 11 rolls randomly to cause the pressure sensor 12 to be triggered by mistake is not easy to occur.

Preferably, a groove 13 for accommodating the trigger ball 11 is formed in the center of the monitor tube 10, and the groove 13 is inclined to the mounting table 1, so that the trigger ball 11 is more likely to fall to the upright post 16 when the monitor tube 10 is inclined. Wherein, for the sake of convenient observation, the monitoring tube 10 may be made of transparent material, such as transparent plastic material. In addition, in order to facilitate leveling of the monitor pipe 10, a slide seat slidable in the vertical direction may also be provided on the side wall of the mounting table 1, and the end of the monitor pipe 10 near the mounting table 1 is hinged to the slide seat, and the slide seat may be fastened to the mounting table 1 by bolts.

The foregoing is merely a preferred embodiment of the utility model, and it is to be understood that the utility model is not limited to the form disclosed herein but is not to be construed as excluding other embodiments, but is capable of numerous other combinations, modifications and environments and is capable of modifications within the scope of the inventive concept, either as taught or as a matter of routine skill or knowledge in the relevant art. And that modifications and variations which do not depart from the spirit and scope of the utility model are intended to be within the scope of the appended claims.
