Description

Technical Field

[0001] The present application relates to the technical field of settlement distance detection, and more specifically, to a road and bridge settlement distance detection mechanism. Background Art

[0002] During the construction process of building projects, in order to ensure the project quality, it is necessary to conduct settlement detection on the completed buildings. Most of the traditional settlement detection devices use spirit levels and plumb tubes to detect the settlement of buildings, and it is impossible to obtain accurate settlement data more intuitively.

[0003] The prior art document with the publication number of CN 221571460 U provides a road and bridge settlement distance detection mechanism. This device inserts the support into the ground through the ground inserting rod, adjusts the length through the telescopic rod, and tightens and fixes it through the positioning knob. The fixed insertion rod is inserted into the surface of the building to be detected. The winch lengthens the steel wire rope to adapt to the distance between the box body and the support. When settlement occurs, the steel wire rope pulls the slider to slide on the surface of the slide rail, thereby driving the rack to move. The rack acts on the gear, and then drives the indicating needle to rotate through the rotating shaft. The indicating needle points on the indicating scale for easy observation. When not in use, the spring drives the slider to reset, thereby driving the indicating needle to reset.

[0004] Although the above prior art solution can achieve relevant beneficial effects through the structure of the prior art, there are still the following defects: when this device is in use, it is impossible to give a warning about the settlement distance, and the steel wire rope of the winch is extremely vulnerable to the influence of thermal expansion and contraction, so there will also be a certain measurement error.

[0005] In view of this, we propose a road and bridge settlement distance detection mechanism. Utility Model Content

[0008] 2. Technical Solutions

[0009] The technical solution of the present application provides a road and bridge settlement distance detection mechanism, including: a positioning frame and a straight ruler rod slidably inserted on the positioning frame. The straight ruler rod can be fixed on the bridge pier, and a warning component is arranged between the positioning frame and the straight ruler rod.

[0010] By adopting the above technical solution, the straight ruler rod is fixed on the building surface to be detected, and the positioning frame is fixed beside the building. At this time, the values of the recording positioning frame and the straight ruler rod are recorded, and then the distance between the warning component and the positioning frame (i.e., the maximum warning settlement distance) is adjusted. When the warning component follows the straight ruler rod and descends, after the warning component fits with the positioning frame, it is powered on to issue an alarm, realizing the warning of immersion. At the same time, the measurement error caused by thermal expansion and contraction can be reduced through the straight ruler rod.

A fixing seat is vertically fixed at the lower end of the straight ruler rod, and a plurality of fixing holes are provided on the fixing seat and the bottom plate.

[0012] By adopting the above technical solution, the straight ruler rod is fixed on the building surface through the fixing seat, the bottom plate is fixed on the ground, and the straight ruler rod is vertically slidably inserted into the lower sleeve. When the building sinks, the straight ruler rod descends, and the initial scale of the lower sleeve and the straight ruler rod, and the corresponding scale after the straight ruler rod descends can be used. The value between the two scales is the settlement distance of the building.

[0013] As an alternative solution of the technical solution of this application document, the warning component includes an upper sleeve sleeved on the straight ruler rod, a storage battery, an audible and visual alarm, a positive contact piece, and a negative contact piece.

When the building sinks, the positive contact piece and the negative contact piece are in electrical contact to form a complete circuit, and at this time the audible and visual alarm is powered on for audible and visual warning.

[0015] As an alternative solution of the technical solution of this application document, a wireless transmission module is also fixedly installed inside the straight ruler rod, and the wireless transmission module is electrically connected to the storage battery.

[0016] By adopting the above technical solution, after the positive contact piece and the negative contact piece are in electrical contact, the wireless transmission module converts the electronic signal into radio waves through wireless signal transmission by the radio frequency circuit, the antenna, and the microcontroller, and sends them to the mobile phone of the inspector through the antenna, so that the inspector can quickly obtain the settlement information.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The following further details the present application with reference to the accompanying drawings of the specification.

[0029] A road and bridge settlement distance detection mechanism includes: a positioning frame 3 and a straight ruler rod 1 slidably inserted on the positioning frame 3. The straight ruler rod 1 can be fixed on the bridge pier, and a warning component 4 is arranged between the positioning frame 3 and the straight ruler rod 1.

[0030] Refer to Figures 1-5 , fix the straight ruler rod 1 on the building surface to be detected, fix the positioning frame 3 beside the building. At this time, record the values of the positioning frame 3 and the straight ruler rod 1, then adjust the distance between the warning component 4 and the positioning frame 3 (that is, the maximum warning settlement distance). And when the warning component 4 descends following the straight ruler rod 1, after the warning component 4 fits with the positioning frame 3, it is powered on to give an alarm, realizing the warning of immersion. At the same time, the measurement error caused by thermal expansion and contraction can be reduced through the straight ruler rod 1.

[0031] The positioning frame 3 includes a vertical rod 31, a bottom plate 32 fixed at the lower end of the vertical rod 31, and a lower sleeve 33 fixed at the other end of the vertical rod 31. The straight ruler rod 1 is slidably inserted into the lower sleeve 33. A fixing seat 2 is vertically fixed at the lower end of the straight ruler rod 1, and a plurality of fixing holes 21 are formed on the fixing seat 2 and the bottom plate 32.

[0032] Refer to Figure 2 and Figure 4 , the straight ruler rod 1 is fixed on the building surface through the fixing seat 2, the bottom plate 32 is fixed on the ground, and the straight ruler rod 1 is vertically slidably inserted into the lower sleeve 33. When the building sinks, the straight ruler rod 1 descends. Then, through the initial scale of the lower sleeve 33 and the straight ruler rod 1, and the corresponding scale after the straight ruler rod 1 descends, the value between the two scales is the settlement distance of the building.

[0033] The warning component 4 includes an upper sleeve 41 sleeved on the straight ruler rod 1, a storage battery 42, a sound and light alarm 43, a positive contact piece 45, and a negative contact piece 46. The straight ruler rod 1 is made of hollow insulating material. The storage battery 42 is fixed inside the straight ruler rod 1. The positive contact piece 45 is fixed on the upper edge of the lower sleeve 33, and the negative contact piece 46 is fixed on the upper edge of the upper sleeve 41. A locking screw 411 that abuts against the straight ruler rod 1 is threadedly connected to one side of the upper sleeve 41.

[0034] Refer to Figures 2-5 , the storage battery 42, the sound and light alarm 43, the positive contact piece 45, and the negative contact piece 46 are connected in series, and the upper sleeve 41 is placed above the lower sleeve 33. By adjusting the distance between the upper sleeve 41 and the lower sleeve 33, the settlement distance of the building is warned. And when the building sinks, the positive contact piece 45 and the negative contact piece 46 are in contact and electrically connected to form a complete circuit. At this time, the sound and light alarm 43 is powered on for sound and light warning.

[0035] A wireless transmission module 44 is also fixedly installed inside the straight ruler rod 1, and the wireless transmission module 44 is electrically connected to the storage battery 42.

[0036] Refer to Figure 3, after the positive contact piece 45 and the negative contact piece 46 are in electrical contact, the wireless transmission module 44 converts the electronic signal into radio waves through wireless signal transmission by the radio frequency circuit, the antenna and the microcontroller, and sends them to the inspector's mobile phone through the antenna, so that the inspector can quickly obtain the settlement information.

[0037] A rainproof cap 5 is fixedly installed at the upper end of the straight ruler rod 1.

[0038] Refer to Figure 1 , the rainproof cap 5 can prevent rain and dust from the positive contact piece 45, the negative contact piece 46 and the sound and light alarm 43.

[0039] Working principle: First, pour a concrete base on the ground beside the building to prevent large settlement when the positioning frame 3 supports on the ground. Then, pass the expansion bolts into the fixing holes 21 to vertically fix the straight ruler rod 1 on the surface of the building to be measured, and fix the bottom plate 32 on the concrete base. At this time, observe the upper edge of the lower sleeve 33 and the scale of the straight ruler rod 1, and then adjust the distance between the lower edge of the upper sleeve 41 and the lower sleeve 33 and fix it with the locking screw 411. This distance is the warning distance. When the building settles, it drives the straight ruler rod 1 to descend, and at the same time drives the upper sleeve 41 and the negative contact piece 46 to descend. When the negative contact piece 46 is in electrical contact with the positive contact piece 45, the sound and light alarm 43 and the wireless transmission module 44 are powered on and operate. The sound and light alarm 43 gives an audible and visual alarm, and the wireless transmission module 44 sends information to the inspector's mobile phone.
