Description

Technical Field

[0001] The utility model relates to a detection device for municipal engineering, in particular to a verticality detection device for municipal engineering. Background Art

[0002] The verticality detection device for municipal engineering includes basic measuring tools, mechanical detection devices, electronic detection instruments, etc. Among them, the basic measuring tools include a plumb bob and a spirit level. The plumb bob is one of the most traditional verticality detection tools, generally composed of a heavy object and a thin string. By observing whether the heavy object is in the vertical direction, the verticality of the object to be measured is determined. Its advantages are simplicity and easy operation. The spirit level is used to detect the horizontal or vertical state of the surface within a small range and is usually an essential basic tool for construction workers. Its advantages are convenient use and easy to carry, but it is also greatly affected by the outside world, and the measurement range and accuracy are limited.

[0003] The mechanical detection devices include a rectangular block mobile device and a lead screw drive device. The rectangular block mobile device detects by placing the rectangular block at the corner of the wall and then operating the moving block to turn upwards. This method has been improved compared with the traditional plumb bob, but there are still problems of cumbersome operation and general accuracy. The lead screw drive device drives the lead screw to rotate through a motor, and then pushes the relevant components to perform verticality detection. This device can improve the degree of automation and reduce manual operation errors, but the structure is relatively complex and requires certain maintenance.

[0004] The electronic detection instruments include a laser rangefinder and an electronic angle detector. The laser rangefinder emits laser to the surface to be measured and calculates the distance according to the time difference of the laser reflected back, and then judges the verticality of the wall surface. The laser rangefinder has the advantages of high precision and fast measurement, but the cost is high and it requires professional personnel to operate. The electronic angle detector detects the inclination angle through the internal sensor, and then calculates the verticality. This type of instrument usually includes a digital display, which can provide intuitive measurement results and is convenient to operate, but the price is also high and there are certain requirements for the use environment.

[0005] As described above, the mechanical detection devices and electronic detection instruments are not suitable for basic operators. Therefore, basic operators still use the traditional basic measuring tools, namely the plumb bob and the spirit level, to detect the verticality of walls, formworks, etc.

[0006] In the prior art, during the process of detecting the verticality with a plumb bob, the operator needs to measure the distances between the wall and the plumb line at multiple places to obtain the result of the verticality of the wall. This result is not very intuitively displayed, and if there is a reading error, it will lead to an incorrect detection result. Summary of the Utility Model

[0007] The main object of the present utility model is to provide a verticality detection device for municipal engineering, so that the detection result can be intuitively displayed, without the need for operators to perform multiple measurements, and to avoid the occurrence of errors in the detection results caused by reading errors.

[0008] To achieve the above object, the present utility model provides a verticality detection device for municipal engineering, comprising:

[0009] A first detection plate, the top of the first detection plate extends outward in the width direction of the first detection plate to form an extension. The top and the extension of the first detection plate are both provided with wire grooves, and the central axis of the wire groove coincides with the central axes of the first detection plate and the extension. A first central axis scale groove is provided on the first detection plate;

[0010] A second detection plate, one end of the second detection plate is hinged to the bottom of the first detection plate through a hinge shaft. The second detection plate can rotate 180 degrees relative to the first detection plate. A second central axis scale groove is provided on the second detection plate, and the first central axis scale groove and the second central axis scale groove are located on the same central axis;

[0011] A plumb line and a plumb bob, one end of the plumb line is fixedly tied to the top of the first detection plate, the other end of the plumb line is fixed to the plumb bob, the plumb line is laid along the wire groove, and the plumb line is naturally straightened and hung down with the plumb bob.

[0012] Preferably, the verticality detection device further comprises two sets of fixing devices, and these two sets of fixing devices are respectively located on both sides of the hinge shaft.

[0013] Further preferably, the fixing device includes a bolt, a first nut and a second nut. The first nut is fixedly embedded on the opposite side of the first detection plate and the second detection plate. The second nut is fixedly embedded on the opposite side of the second detection plate and the first detection plate. The first nut and the second nut are coaxially arranged, and the bolt is screwed to the first nut and the second nut respectively.

[0014] Even more preferably, the first detection plate is provided with a first through hole, the second detection plate is provided with a second blind hole, the first nut is coaxially arranged with the first through hole, the second blind hole is coaxially arranged with the second nut, and one end of the bolt passes through the first through hole and then extends into the second blind hole.

[0015] Preferably, the corners of the wire grooves are all set to be rounded.

[0016] Preferably, a wire pulling column is provided on the side of the first detection plate opposite to the extension, and the starting end of the plumb line is tied to the wire pulling column.

[0017] The beneficial effects of the present utility model are:

[0018] In the present utility model, a plumb line and a plumb bob are fixed on a first detection plate, and a first central axis scale groove and a second central axis scale groove are respectively marked on the first detection plate and the second detection plate. In this way, when the plumb bob is in the natural hanging process, the plumb line coincides with the first central axis scale groove and the second central axis scale groove. When the side surface of the first detection plate is attached to the wall, if the plumb line still coincides with the first central axis scale groove, it indicates that the wall is vertical. If the plumb line deviates from the first central axis scale groove and the second central axis scale groove, it indicates that the wall is not vertical, and subsequent processing is carried out according to the actual situation. In addition, if the wall is relatively high, the second detection plate can be rotated so that the side of the second detection plate for attaching to the wall and the side of the first detection plate for attaching to the wall are in the same plane. In this way, the length of the detection device can be extended, thereby detecting the wall. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following clearly and completely describes the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Many specific details are set forth in the following description in order to fully understand the present utility model, but the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0030] As Figure 1 shown, this embodiment provides a verticality detection device for municipal engineering, including a first detection plate 100, a second detection plate 200, a plumb line 520, and a plumb bob 510. Among them, both the first detection plate 100 and the second detection plate 200 are long strip plates with a certain thickness, so that the sides of the first detection plate 100 and the second detection plate 200 can be attached to the wall surface. One end of the plumb line 520 winds from one side of the first detection plate 100 to the other side of the first detection plate 100, and this end is fixedly connected to the plumb bob 510. In this way, under the action of gravity, the plumb line 520 naturally hangs vertically downward.

[0031] Specifically, in this embodiment, as Figures 1 to 3 shown, an extension 110 is formed by extending outward in the width direction of the top of the first detection plate 100 towards the top of the first detection plate 100. Wire grooves 120 are provided on both the top of the first detection plate 100 and the extension 110. The central axis of the wire groove 120 coincides with the central axes of the first detection plate 100 and the extension 110. A first central axis scale groove 141 is provided on the first detection plate 100. In this way, the plumb line 520 is laid along the wire groove 120. After naturally hanging down, the plumb line 520 coincides with the first central axis scale groove 141. In order to prevent the plumb line 520 from breaking, the corners of the wire groove 120 can be set to be rounded. In addition, a wire pulling post 130 can also be provided on the side of the first detection plate 100 opposite to the extension 110, and the starting end of the plumb line 520 is tied to the wire pulling post 130.

[0032] One end of the second detection plate 200 is hinged to the bottom of the first detection plate 100 through a hinge shaft 300. In order to prevent the hinge shaft 300 from affecting the plumb line 520, the shaft cap of the hinge shaft 300 can be sunk into the second detection plate 200. The second detection plate 200 can rotate 180 degrees relative to the first detection plate 100. Similarly, a second central axis scale groove 210 is provided on the second detection plate 200. The first central axis scale groove 141 and the second central axis scale groove 210 are located on the same central axis. In this embodiment, the widths of the first detection plate 100 and the second detection plate 200 are the same. When the length of the first detection plate 100 is insufficient, the second detection plate 200 can be rotated to increase the length of the entire verticality detection device.

[0033] In this embodiment, in order to prevent the second detection plate 200 from rotating relative to the first detection plate 100 during the detection process, the perpendicularity detection device further includes two sets of fixing devices, and these two sets of fixing devices are respectively located on both sides of the hinge shaft 300. Specifically, the fixing device includes a bolt 410, a first nut 420, and a second nut 430. A first through hole is provided on the first detection plate 100, and a second blind hole is provided on the second detection plate. The first nut 420 is coaxially arranged with the first through hole, the second blind hole is coaxially arranged with the second nut 430, and at the same time, the first through hole is coaxially arranged with the second blind hole. One end of the bolt 410 passes through the first through hole and extends into the second blind hole. The first nut 420 is fixedly embedded on the opposite side of the first detection plate 100 and the second detection plate 200, and the second nut 430 is fixedly embedded on the opposite side of the second detection plate 200 and the first detection plate 100. The bolt 410 is screwed to the first nut 420 and the second nut 430 respectively.

[0034] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.
