Description

Technical Field

[0001] This utility model belongs to the field of building settlement and deformation monitoring technology, and specifically relates to an observation pier. Background Technology

[0002] As is well known, construction around existing buildings and operating railways will inevitably affect the surrounding soil, causing settlement and deformation of the existing buildings and operating railways. During construction, monitoring the settlement and deformation of existing buildings and operating railways can promptly feed back a series of dynamic changes caused by construction to the construction unit, enabling them to adjust construction parameters and optimize construction methods on site in a timely manner to avoid endangering the safety of existing buildings and railway operation.

[0003] Currently, the common practice for dynamic monitoring is to set up monitoring piers around the construction site and mount measuring instruments on them for dynamic monitoring of the construction. For example, existing technology discloses an invention patent entitled "Settlement Deformation Monitoring Piles and Their Support Construction Method" (Authorization Announcement No.: CN 106759218 B). However, this protective cover involves setting up multiple support arms under the canopy, which can obstruct part of the view and affect the signal reception of the measuring instruments. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide an observation pier that can reduce the obstruction of the observation line of the measuring instrument and at the same time protect the measuring instrument.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An observation pier includes a pier body and a forced centering plate disposed on the top of the pier body. The pier body further includes a support base and a protective cover. A single support base is installed on the pier body and located on one side of the forced centering plate. The protective cover is rotatably connected to the support base, such that the protective cover is tilted above the forced centering plate. The vertical distance between the outer side of the protective cover and the pier body is greater than the vertical distance between the inner side of the protective cover and the pier body.

[0007] Furthermore, it also includes a rotary connection assembly, which includes a turntable and a rotating shaft. The turntable is fixed to the top of the pier, and the rotating shaft rotates in the horizontal plane on the turntable with the center of the forced centering plate as the rotation center. The support base is installed on the rotating shaft.

[0008] Furthermore, a limiting plate is provided at the bottom of the rotating shaft, and the turntable has a connected slot 1 and slot 2. The center of slot 1 coincides with the center of the forced centering plate. The rotating shaft passes through slot 1, and the limiting plate is located in slot 2. The rotating shaft is vertically limited on the turntable and rotates along slot 1.

[0009] Furthermore, the support base is provided with a through hole, through which the rotating shaft passes, and a nut is threadedly connected to the rotating shaft.

[0010] Furthermore, the turntable includes a chassis, component one, and component two. Component one has a cutting groove one at its bottom, and component two has a cutting groove two at its bottom. Component one and component two are fixed on the chassis. Cutting groove one and cutting groove two form a slot two, and slot one is formed between component one and component two.

[0011] Furthermore, component one and component two are fixed to the chassis by welding.

[0012] Furthermore, the protective cover is provided with a first ear plate, the support base is provided with a second ear plate, the second ear plate is provided with a first threaded post, the first threaded post passes through the mounting hole of the first ear plate, the first threaded post is threadedly connected to a second nut, the second nut and the second ear plate fix the first ear plate.

[0013] Furthermore, a reinforcing plate is welded between the protective cover and the ear plate.

[0014] Furthermore, the support base is provided with a through hole two, and the ear plate two is provided with a threaded post two. The threaded post two passes through the through hole two and moves vertically in the through hole two. The threaded post two is threadedly connected to a nut three, and the nut three and the ear plate two fix the support base.

[0015] Furthermore, a baffle is provided on one side of the protective cover.

[0016] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0017] (1) The protective cover of this utility model is supported at a single point on the top of the pier by a support base. The inclined cover itself will block part of the view. Apart from the support base itself, there are no other vertical structures that block the view.

[0018] Furthermore, the protective cover is tilted, creating a wide observation window. The main observation targets (such as prisms) of surveying instruments (such as total stations) are usually located in the horizontal and vertical directions. By aligning the side of the protective cover with the larger distance towards these key observation directions, the surveying instrument gains a wide field of view, reducing obstruction of the instrument's line of sight.

[0019] (2) The sloping cover can effectively prevent rain and snow from accumulating on the top and allow them to slide off smoothly. At the same time, it can block most of the direct sunlight and rain, providing a relatively stable environment for the instrument and preventing damage or loss of accuracy due to overheating, overcooling or dampness.

[0020] At the same time, the protective cover forms a physical barrier that can prevent accidental collisions, falling branches, or interference from birds, thus protecting the measuring instruments. Attached Figure Description

[0038] like Figures 1 to 10As shown, this is an observation pier of the present invention.

[0039] Example 1

[0040] The observation pier provided by this utility model includes a pier body 1, a forced centering plate 2, a support base 3, and a protective cover 4.

[0041] The pier body 1 is a stable foundation made of concrete. Anchor bolts 21 are pre-embedded inside. The forced centering plate 2 is precisely and firmly installed at the center of the top of the pier body 1 through the anchor bolts 21. It is used to install and fix measuring instruments (such as total stations) to ensure the centering accuracy of the instruments.

[0042] This utility model uses a single support 3 installed on the top of the pier body 1, and its installation position is located on one side of the forced centering plate 2.

[0043] The protective cover 4 is an inclined cover that is rotatably connected to the support base 3 via a hinge point. This single-point support and hinged connection method allows the protective cover 4 to be stably tilted and suspended above the forced centering plate 2 and the measuring instrument.

[0044] like Figure 2 As shown, the vertical distance between the outer side a (the side away from support 3) of the protective cover and the pier 1 is L2, and the vertical distance between the inner side b (the side closer to support 3) of the protective cover and the pier 1 is L1, satisfying L2>L1. This asymmetrical design essentially raises the entire protective cover 4 and tilts it to one side, thus creating a wide observation window facing the "L2" side for the measuring instrument. The main observation targets of the measuring instrument (such as prisms in the horizontal and elevation directions) are all located in this direction, thus reducing the obstruction of the instrument's line of sight by the protective cover 4.

[0045] Meanwhile, the inclined cover effectively prevents rain and snow accumulation and guides them to slide off, while also blocking most direct sunlight and rain, providing a stable temperature and humidity environment for the instrument. The protective cover 4 itself also constitutes a physical barrier, preventing interference from accidental collisions, falling rocks, etc., thus effectively protecting the measuring instrument. To enhance the protective effect of the protective cover 4, a baffle 41 is welded to the outside of the protective cover.

[0046] Implementation 2

[0047] Based on the structure of Embodiment 1, this embodiment further optimizes the installation method of the support base 3, enabling it to rotate.

[0048] This invention also includes a rotating connection assembly comprising a turntable 51 and a rotating shaft 52. A through hole 31 is provided at the bottom of the support base 3, through which the rotating shaft 52 passes. A nut 53 is threadedly connected to the rotating shaft 52 and tightened onto the support base 3. The bottom of the support base 3 is mounted on the rotating shaft 52. The turntable 51 is pre-embedded in the top of the pier body 1. When the nut 53 is loosened, the rotating shaft 52 is rotatably mounted on the turntable 51 with the center point of the forced centering plate 2 as its rotation center. With this structure, rotating the rotating shaft 52 can drive the entire support base 3 and the protective cover 4 to rotate 360° in the horizontal plane with the center of the forced centering plate 2 as its axis. This function allows the user to adjust the orientation of the open side (L2 side) of the protective cover 4 at any time according to actual observation needs to achieve the optimal position for observation.

[0049] To vertically limit the rotation shaft 52 and facilitate installation, a limiting plate 52a is welded to the bottom of the rotation shaft 52. Correspondingly, the turntable 51 has two interconnected slots, a first slot 514 and a second slot 515. The center of the first slot 514 coincides with the center of the forced centering plate 22, and its shape is arc-shaped, allowing the rotation shaft 52 to rotate along its trajectory. The second slot 515 is larger than the limiting plate 52a, facilitating the installation of the limiting plate 52a. At this time, the limiting plate 52a is restricted on the turntable 51, so that the rotation shaft 52 is vertically limited and cannot be pulled out, but can rotate freely along the first slot 514.

[0050] In a preferred embodiment, the turntable 51 can be assembled from a base 511, component one 512, and component two 513. Component one 512 and component two 513 are welded to the base 511, and the gap between them forms a slot one 514. Cutting grooves one 512a and two 513a are respectively machined on the bottom of component one 512 and component two 513. When they are welded to the base 511, these two cutting grooves combine to form slot two 515. This split structure facilitates machining and ensures assembly accuracy.

[0051] Example 3

[0052] Based on the structure of Embodiment 1 or Embodiment 2, this embodiment further describes in detail the hinge structure between the protective cover 4 and the support base 3 to realize the tilt angle adjustment of the protective cover 4.

[0053] Ear plate 42 is welded onto the protective cover 4. Correspondingly, ear plate 43 is provided on the support base 3, and threaded post 44 is welded onto ear plate 43. During installation, the mounting hole on ear plate 42 is inserted into threaded post 44, and then nut 45 is tightened on threaded post 44. Nut 45 and ear plate 43 fix ear plate 42, thus fastening ear plate 42 to ear plate 43, forming a hinge. This connection method allows for fine adjustment of the tilt angle of the protective cover 4 before final tightening. To enhance the connection strength, a reinforcing plate 48 is welded at the weld between the protective cover 4 and ear plate 42.

[0054] To adjust the height of the ear plate 43 on the support base 3, thereby fine-tuning the overall height of the protective cover 4, a threaded post 46 is welded onto the ear plate 43. This threaded post 46 passes through the through hole 32 of the support base 3. By tightening or loosening the nut 47 on the threaded post 46, the support base 3 can be clamped or released, thus achieving vertical position adjustment and locking of the protective cover 4.

[0055] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
