It is convenient to use, has good flexibility, is conducive to promotion, and can also level the base to ensure the accuracy of subsequent observation data.
[0003] However, the aforementioned device, designed to measure the height of the bridge bottom, is a large-scale structure. This bulky structure not only has high material costs and high energy consumption in manufacturing, but also requires multiple people to assist in handling and is difficult to move. It is also prone to swaying and tipping over in narrow spaces, ultimately resulting in low detection efficiency and insufficient coverage of monitoring points. To address this, we propose a foldable bridge settlement observation frame. Utility Model Content
[0004] The purpose of this invention is to provide a foldable bridge settlement observation frame, which can solve the problem that some existing devices are too bulky and affect their use.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a foldable bridge settlement observation frame, comprising: A base plate, on which a fixing plate is fixedly installed, and a top plate is attached to the top of the base plate. At least two sets of connecting plates are provided between the fixing plate and the top plate. The fixing plate and the top plate are hinged to the adjacent connecting plates, and the two adjacent sets of connecting plates are hinged to each other. The observation mechanism, located on top of the roof slab, is used to monitor bridge settlement. The snap-fit mechanism is set on the fixed plate and each connecting plate. The snap-fit mechanism includes a groove, a snap-fit rod and a return spring. A set of grooves is opened on the fixed plate and each connecting plate. A set of snap-fit rods is movably set in each set of grooves. A set of return springs is fixedly installed between one end of each set of snap-fit rods and the inner wall of the corresponding groove.
[0006] Preferably, the snap-fit mechanism further includes a through groove and a lever. A set of through grooves communicating with the interior of the corresponding grooves are provided on one side of the fixed plate and each connecting plate. A set of levers is fixedly installed on the outer surface of each set of snap-fit levers. Each set of levers is set in the corresponding through groove. A set of snap-fit holes are provided on the top plate and each connecting plate.
[0007] Preferably, the observation mechanism includes an electric push rod, a sleeve, an observation scale, a connecting rod, and a limiting sleeve. The electric push rod is fixedly installed inside the top plate, and the sleeve is fixedly installed at the free end of the electric push rod. The observation scale is movably mounted on the sleeve, and a spring assembly is fixedly installed between the bottom of the observation scale and the inner bottom of the sleeve. The connecting rod is fixedly installed on one outer surface of the top plate, and a limiting sleeve is fixedly installed at one end of the connecting rod. The limiting sleeve is fitted onto the observation scale.
[0008] Preferably, a storage battery is fixedly installed on one outer surface of the top plate.

Each set of support columns has a set of through rods fixedly installed on its top, and the base plate is movably sleeved on each set of through rods.
[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) The foldable bridge settlement observation frame can be folded and assembled by the cooperation of the fixed plate, top plate, connecting plate and snap-fit mechanism to realize the storage and unfolding of the observation frame. When stored, it is convenient for users to move and transport it. It solves the problem that some existing devices adopt a large overall size design for measuring the height of the bridge bottom. This huge structure not only has high material cost and high manufacturing energy consumption, but also requires many people to assist in the transport and is difficult to move. It is also more likely to shake and tip over in narrow spaces, which ultimately leads to low detection efficiency and insufficient coverage of monitoring points. This improves the practicality of the observation frame.
[0013] (2) The foldable bridge settlement observation frame can measure the settlement of the bridge through the observation mechanism. At the same time, under the action of the support column and the through rod, the pre-embedded plate can be directly discarded after the observation is completed, which is convenient for disassembly and assembly, ensuring the effectiveness of the observation frame and facilitating its promotion and use.

[0017] Please see Figure 1-4 This utility model provides a technical solution: a foldable bridge settlement observation frame, including a base plate 1, an observation mechanism 6 and a snap-fit mechanism 5. A fixing plate 2 is fixedly installed on the top of the base plate 1, and a top plate 3 is attached to the top of the base plate 1. At least two sets of connecting plates 4 are provided between the fixing plate 2 and the top plate 3. The fixing plate 2 and the top plate 3 are hinged to the adjacent connecting plates 4. The two adjacent sets of connecting plates 4 are hinged to each other. The observation mechanism 6 is located on the top of the top plate 3 and is used to observe bridge settlement. A battery 8 is fixedly installed on one outer surface of the top plate 3. Two sets of handles 9 are fixedly installed on the top of the base plate 1. A support plate 10 is fixedly installed on one outer surface of the base plate 1. A level bubble meter 11 is fixedly installed on the top of the support plate 10. An embedded plate 12 is provided directly below the base plate 1. At least two sets of support columns 13 are fixedly installed on the top of the embedded plate 12. A set of through rods 14 is fixedly installed on the top of each set of support columns 13. The base plate 1 is movably sleeved on each set of through rods 14. The snap-fit mechanism 5 is provided on the fixed plate 2 and each connecting plate 4. The snap-fit mechanism 5 includes a groove 51, a snap-fit rod 52 and a return spring 53. A set of grooves 51 are provided on the fixed plate 2 and each connecting plate 4. A set of snap-fit rods 52 are movably arranged in each set of grooves 51. A set of return springs 53 is fixedly installed between one end of each set of snap-fit rods 52 and the inner wall of the corresponding groove 51.
[0018] The locking mechanism 5 also includes a through slot 54 and a lever 55. A set of through slots 54 communicating with the inside of the corresponding groove 51 are opened on one side of the fixed plate 2 and each connecting plate 4. A set of levers 55 are fixedly installed on the outer surface of each set of locking levers 52. Each set of levers 55 is set in the corresponding through slot 54. A set of locking holes 7 are opened on the top plate 3 and each connecting plate 4. Through the cooperation of the fixed plate 2, the top plate 3, the connecting plate 4 and the locking mechanism 5, the fixed plate 2, the top plate 3 and the connecting plate 4 can be folded and assembled to realize the storage and unfolding of the observation frame. When stored, it is convenient for users to move and transport it. This solves the problem that some existing devices adopt a large overall size design for measuring the height of the bridge bottom. This huge structure not only has high material cost and high manufacturing energy consumption, but also requires many people to assist in the transport and is difficult to move. It is also more prone to shaking and tipping in narrow spaces, which ultimately leads to low detection efficiency and insufficient coverage of monitoring points. This improves the practicality of the observation frame.
[0019] The observation mechanism 6 includes an electric push rod 61, a sleeve 62, an observation ruler 63, a connecting rod 64, and a limiting sleeve 65. The electric push rod 61 is fixedly installed inside the top plate 3. The sleeve 62 is fixedly installed at the free end of the electric push rod 61.

The connecting rod 64 is fixedly installed on one outer surface of the top plate 3. The limiting sleeve 65 is fixedly installed at one end of the connecting rod 64 and is fitted onto the observation ruler 63. Through the observation mechanism 6, the bridge settlement can be measured. At the same time, under the action of the support column 13 and the through rod 14, the pre-embedded plate 12 can be directly discarded after the observation is completed, which is convenient for disassembly and assembly, ensuring the effectiveness of the observation frame and facilitating its promotion and use.
[0020] Working principle: In use, the pre-embedded plate 12 is first pre-embedded underground. During pre-embedding, the balance of the base plate 1 is maintained by observing the level bubble meter 11. Then, the top plate 3 and each connecting plate 4 are rotated and lifted in sequence to be on the same vertical plane as the fixed plate 2. During this process, the locking mechanisms 5 on the fixed plate 2 and each connecting plate 4 are operated in sequence. That is, first, the lever 55 on the fixed plate 2 is moved to drive the locking rod 52 into the groove 51 and compress the return spring 53. When the adjacent connecting plate 4 of the fixed plate 2 is on the same vertical plane, the lever 55 is released and the return spring 53 is compressed. Under the rebound action of 3, the locking rod 52 is inserted into the locking hole 7 on the adjacent connecting plate 4. This process is repeated until the fixing plate 2 and each connecting plate 4 are located on the same vertical plane. Then, the free end of the electric push rod 61 is controlled to extend and retract, driving the sleeve 62 and the observation ruler 63 to move, so that the observation ruler 63 is against the bridge and the scale is recorded. When the bridge settles, the observation ruler 63 will be pressed down to retract into the sleeve 62 and the scale change will be recorded. The bridge settlement data can be obtained. After the observation is completed, the top plate 3 and each connecting plate 4 are folded back to their original positions, and the bottom plate 1 can be removed directly.
[0021] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
