Description
Technical Field
[0001] This utility model relates to the technical field of construction monitoring, and in particular to a simple benchmark deformation monitoring device for the construction of large-span structures. Background Technology
[0002] The simple benchmark deformation monitoring device for large-span structure construction is a device that can monitor the deformation of benchmark points in real time during the construction process of large-span structures. It is usually composed of sensors, data acquisition devices, data transmission devices and data analysis software. When the deformation of the benchmark point exceeds the preset threshold, the device can issue an early warning signal in time to remind construction personnel to take corresponding measures to avoid safety accidents. However, deformation monitoring devices are often installed at construction site monitoring points, making the devices themselves located on the construction site. As a result, during long-term monitoring, they are extremely susceptible to collisions with external objects, which can significantly shorten the lifespan of the monitoring devices and cause interference with the monitoring information, making it impossible to collect important data in a timely manner, thus posing hidden safety hazards.
[0003] Therefore, this utility model provides a simple benchmark deformation monitoring device for the construction of large-span structures. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0022] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a simple benchmark deformation monitoring device for the construction of large-span structures, including a monitoring surface 1 and an array displacement meter 2. The array displacement meter 2 is installed on the side end of the monitoring surface 1 to monitor the deformation of the monitoring surface 1. A fixing bracket 3 is fixedly connected to the surface of the array displacement meter 2. The side end of the fixing bracket 3 is fixedly connected to the monitoring surface 1 by bolts, so that the array displacement meter 2 can be fixed on the side end of the monitoring surface 1. A protective cover 4 is provided on the side end of the array displacement meter 2. A positioning mechanism 5 is provided on the side end of the fixing bracket 3. The positioning mechanism 5 includes... The protective cover 4 includes a positioning base 501, a positioning groove 502, an insert block 503, a positioning block 504, a first spring 505, and a guide rod 506. The side end of the protective cover 4 is provided with a disassembly mechanism 6. The disassembly mechanism 6 includes a pressing plate 601, a sliding bracket 602, a second spring 603, a slider 604, a sliding groove 605, and a recovery inclined surface 606. When the array displacement meter 2 is set on the side end of the monitoring surface 1, the protective cover 4 can be quickly fixed to the side end of the fixed bracket 3 through the positioning mechanism 5. The protective cover 4 protects the array displacement meter 2, thereby preventing damage to the surface of the array displacement meter 2 due to external impact.
[0023] like Figure 1 - Figure 3 As shown: The side end of the positioning base 501 is fixedly connected to the fixed bracket 3. The positioning groove 502 is formed inside the positioning base 501. The side end of the insert block 503 is fixedly connected to the protective cover 4. The protective cover 4 is fixed to the side end of the array displacement meter 2 by the insert block 503. The surface of the insert block 503 is slidably connected to the positioning base 501 through the positioning groove 502. The surface of the positioning block 504 is slidably connected to the insert block 503. The positioning block 504 and the insert block 503 are adapted to each other. The two ends of the first spring 505 are respectively fixed to the positioning block 504. The connection involves a first spring 505 with two positioning blocks 504. The first spring 505 pushes the two positioning blocks 504 to move. The surface of the guide rod 506 is slidably connected to the positioning blocks 504. The outer circumference of the guide rod 506 is equal to the inner circumference of the positioning blocks 504. When the insert block 503 is inserted into the positioning groove 502, the two positioning blocks 504 slide out from the inside of the insert block 503 by the push of the first spring 505, thereby fixing the insert block 503 in the positioning base 501, achieving a quick installation and positioning effect for the protective cover 4.
[0024] like Figure 1 - Figure 3As shown: The surface of the pressing plate 601 is slidably connected to the insert block 503. There are two pressing plates 601. The side end of the sliding bracket 602 is fixedly connected to the pressing plate 601. The fixed end of the second spring 603 is fixedly connected to the protective cover 4. The end of the second spring 603 is fixedly connected to the sliding bracket 602. When the pressing plate 601 is pressed, the pressing plate 601 drives the sliding bracket 602 to move inward, and the second spring 603 can push the sliding bracket 602 to move outward.
[0025] like Figure 1 - Figure 3 As shown: The surface of slider 604 is fixedly connected to the end of sliding bracket 602. There are four sliders 604. The surface of positioning block 504 is provided with sliding groove 605. There are four sliding grooves 605. The lower end of slider 604 is slidably connected to positioning block 504 through sliding groove 605. Slider 604 and sliding groove 605 are adapted to each other. When sliding bracket 602 drives slider 604 to move, positioning block 504 can also bear tension at the same time.
[0026] like Figure 1 - Figure 3 As shown: The side end of the positioning block 504 is provided with a retraction slope 606. The retraction slope 606 is a slope. The positioning block 504 is slidably connected to the insertion block 503 through the retraction slope 606. When the sliding bracket 602 moves, it drives the positioning block 504 to move outward, so that the retraction slope 606 is pressed by the insertion block 503 and drives the positioning block 504 to retract into the insertion block 503. At this time, the protective cover 4 can be removed.
[0027] like Figure 1 - Figure 4 As shown: The protective shield 4 is provided with an extension mechanism 7 on its side. The extension mechanism 7 includes a sealing plate 701, a push plate 702, a push seat 703 and a third spring 704. The surface of the sealing plate 701 is slidably connected to the protective shield 4. The sealing plate 701 is adapted to the protective shield 4. When the sealing plate 701 is extended until its side end contacts the monitoring surface 1, it can protect the array displacement meter 2 from the upper and lower sides to avoid being hit or impacted by falling objects and splashing objects, which would damage the array displacement meter 2.
[0028] like Figure 1 - Figure 4As shown: the side end of the push plate 702 is fixedly connected to the sealing plate 701, and the push plate 702 can drive the sealing plate 701 to move. The side end of the push seat 703 is fixedly connected to the protective cover 4. The fixed end of the third spring 704 is fixedly connected to the push seat 703, and the end of the third spring 704 is fixedly connected to the push plate 702. When the protective cover 4 is installed, the push plate 702 is pushed by the push seat 703, which causes the sealing plate 701 to extend out of the protective cover 4 until the side end of the sealing plate 701 contacts the monitoring surface 1. This allows the array displacement meter 2 to provide coverage protection on both the upper and lower sides within a certain range, even if it is set at an angle or other position.
[0029] Working principle: like Figure 1 - Figure 4 As shown, this adjustable feeding device for silicon steel strip, when the array displacement meter 2 is set on the side of the monitoring surface 1, after inserting the insert block 503 into the positioning groove 502, the two positioning blocks 504 slide out from the inside of the insert block 503 by the push of the first spring 505, thereby fixing the insert block 503 in the positioning base 501, realizing the quick installation and positioning effect of the protective cover 4. The protective cover 4 can be quickly fixed to the side of the fixed bracket 3 by the positioning mechanism 5, and the protective cover 4 protects it, thereby preventing the array displacement meter 2 from being damaged by external force collision. When the button plate 601 is pressed, the button plate 601 drives the sliding bracket 602 to move inward. When the sliding bracket 602 moves, it drives the positioning block 504 to move outward, so that the recovery slope 606 is pressed by the insert block 503 and drives the positioning block 504 to retract into the inside of the insert block 503. At this time, the protective cover 4 can be removed. After the protective shield 4 is installed, the push plate 702 is pushed by the push base 703, which causes the sealing plate 701 to extend out of the protective shield 4 until the side end of the sealing plate 701 contacts the monitoring surface 1. This ensures that even if the array displacement meter 2 is set at an angle or other position, it can still provide top and bottom coverage protection within a certain range, thereby preventing falling objects and flying objects from hitting and impacting the array displacement meter 2, which would cause damage.
[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
