Description

Technical Field

[0001] This utility model relates to the field of infrastructure construction technology, and in particular to a precast box culvert joint detection device. Background Technology

[0002] Precast box culverts are a common construction method for underground utility tunnels. During on-site assembly, the foundation for the box culvert is usually constructed first, and then the new box culvert is inserted and connected to the existing ones. For small precast box culverts (generally 1.2 to 2.4 meters), hoisting or direct jacking methods are typically used for connection. When moving and connecting box culverts, the orientation of the moving culvert needs to be adjusted to prevent obstruction at the spigot and socket joints, and even damage to the sealing strips in some cases. The vertical angle of the box culvert is controlled by adjusting the construction accuracy of the foundation. Adjusting the horizontal orientation is a crucial step. Currently, the method for determining whether a box culvert is tilted horizontally involves manually measuring the distance between the ends of the two box culverts on their two sides as they approach each other. If the measured distances on the two sides differ significantly, adjustments are made.

[0003] This method requires coordination between personnel on both sides of the box culvert, which is difficult to implement and control for accuracy. Therefore, the applicant proposes a box culvert joint detection device. Utility Model Content

[0021] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0022] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0023] Furthermore, it should be understood in the description of this utility model that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two main bodies at the connection point are not connected by an intermediate structure, but are simply connected to form a whole through a connecting structure. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0025] In this utility model, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0026] In this utility model, such as Figures 1 to 4As shown, a precast box culvert joint detection device is provided, comprising: a fixed bracket, the fixed bracket including a frame body 1 and a positioning plate 2 disposed at one end of the frame body 1; at least two detection rods 3, one end of each detection rod 3 forming a detection end that can extend from one side of the positioning plate 2, and the detection rods 3 being spaced apart along a direction perpendicular to the axis of the detection rods 3; and a detection assembly including a sensor 4 disposed at the detection end and a display element connected to the sensor 4, wherein the display element is triggered to display when the sensor 4 is pressed.

[0027] In use, the joint detection device of this utility model places the fixed bracket on the top surface of the installed box culvert and aligns the positioning plate 2 with the end face of the box culvert to be joined. At this time, the detection end of the detection rod 3 extends beyond the end face of the box culvert to be joined. During the movement of the newly placed box culvert, it contacts the detection ends of multiple detection rods 3. When the detection sections of all detection rods 3 are triggered simultaneously, the display is activated. This indicates that the horizontal orientation of the newly placed box culvert is normal, and the movement of the box culvert can continue. When the detection rods 3 are not triggered simultaneously, the operator can observe the distance between the detection ends of each detection rod 3 and the end face of the newly placed box culvert (the triggered sensor 4 is in contact with the newly placed box culvert, while there is a gap between the untriggered sensor 4 and the newly placed box culvert). If this distance is significantly excessive, the horizontal orientation of the box culvert can be adjusted.

[0028] In a preferred embodiment, more specifically regarding the structure of this utility model, the display element is configured as a display lamp 5.

[0029] In a preferred embodiment, more specifically, regarding the structure of this utility model, the detection rod 3 is slidably connected to the fixed bracket.

[0030] Therefore, when testing is required, the box culvert can be moved to the testing end near each testing rod 3, and the testing can be carried out by synchronously moving each testing rod 3.

[0031] In a preferred embodiment, specifically regarding the structure of this invention, two detection rods 3 are provided, and the two detection rods 3 are connected by a connecting frame. As shown in the figure, this ensures the synchronicity of the movement of the two detection rods 3.

[0032] In a preferred embodiment, more specifically regarding the structure of this utility model, the connecting frame includes two connecting rods 6.

[0033] As shown in the figure, this arrangement makes the two connecting rods 6 and the two detection rods 3 form a frame shape, which makes the relative position of the detection rods 3 more stable.

[0034] In a preferred embodiment, more specifically regarding the structure of this utility model, the detection component includes a housing 7, the housing 7 having a cavity for inserting and cooperating with the detection rod 3, the sensor 4 being mounted on the surface of the housing 7 away from the detection rod 3, the display being mounted on the housing 7, and the housing 7 having an accommodating space inside.

[0035] With this configuration, the sensor 4 and display can be assembled in the housing 7, and electronic components such as the circuit board and battery can be placed in the accommodating space. This allows the detection assembly to be fabricated separately and then installed on the detection rod 3 for further processing convenience.

[0036] In a preferred embodiment, more specifically regarding the structure of this utility model, the display element includes a display lamp 5 disposed on the top of the housing 7.

[0037] In a preferred embodiment, more specifically regarding the structure of this utility model, the detection device further includes a bolt 8, which passes through the outer casing 7 and is fixed to the detection rod 3.

[0038] In a preferred embodiment, more specifically regarding the structure of this utility model, the detection rod 3 has a slot 9 on the section facing the outer shell 7, and the outer shell 7 has an insertion rail 10 that fits into the slot 9.
