Description

Technical Field

[0001] The utility model relates to the technical field of bridge detection equipment, and particularly relates to a pier offset detection device. Background Art

[0002] A pier is a structure that supports the bridge span structure and transmits the dead load and vehicle live load to the foundation. The abutments are located at both ends of the bridge, and the piers are located between the two abutments. The function of the pier is to support the bridge span structure. In addition to supporting the bridge span structure, the abutment also needs to be connected to the embankment and prevent the embankment from slipping. To protect the abutment and the embankment fill, some protection and diversion projects are often carried out on both sides of the abutment. During the use of the bridge, due to the uneven settlement of the lower foundation and external loads, the pier will tilt. The tilt of the pier will cause the bridge deck to tilt, thus affecting the safety of the vehicles driving on the bridge deck. The pier plays a crucial role in bridge engineering. Its design and construction need to comprehensively consider various factors to ensure the safety and stability of the bridge. During the construction of the pier, a pier offset detection device is required to detect and process the offset of the pier. However, during the use of the existing pier offset detection devices, they cannot detect and process the offsets of piers with different heights. Content of the Utility Model

[0003] Technical Problem to be Solved by the Utility Model

[0004] Aiming at the technical problem that the existing pier offset detection devices cannot detect and process the offsets of piers with different heights during use, the utility model provides a pier offset detection device, which can conveniently detect the offsets of piers with different heights.

[0005] Technical Solution

[0006] To solve the above problems, the technical solution provided by the utility model is as follows:

[0007] A pier offset detection device includes a support bottom plate, which is provided with an opening groove for accommodating a pier, and a support frame symmetrically arranged with respect to the opening groove is fixedly connected thereto; a first-level height adjustment component, including a support frame vertically slidably connected to the support frame, a rack plate is arranged on the support frame, and a driving gear cooperating with the rack plate is arranged on the support frame; a second-level height adjustment component, including a one-way screw vertically arranged on the support frame and a moving support plate vertically connected to the one-way screw, the moving support plate is horizontally arranged; a measuring component, which is horizontally slidably connected to the moving support plate.

[0008] The support base plate serves as the foundation of the entire system, providing a stable support surface. The opening slot is used to position the device around the pier, ensuring that the center line of the device is aligned with the center line of the pier. The support frame is fixed above the support base plate and is symmetrically arranged around the opening slot. The support frame provides fixed points for subsequent components. A rack plate is installed on the support frame, and a driving gear is installed on the support frame. The vertical adjustment is achieved through the meshing of the gear and the rack. The moving support plate is connected to the one-way screw through a thread, and the moving support plate moves up and down by rotating the one-way screw. The secondary height adjustment component rises and falls based on the primary height adjustment component, expanding the detection height range of the detection device. The measurement component is horizontally slidably connected to the moving support plate and can be adjusted in the horizontal direction.

[0009] Optionally, rollers and brakes are provided below the support base plate.

[0010] The rollers enable the device to move easily on the ground, facilitating the rapid deployment of the device to the location where detection is required. The brakes are usually used in conjunction with each roller to lock the rollers and prevent the device from moving accidentally during the detection process.

[0011] Optionally, the support frame is provided with guide rods, and the support frame is fixedly connected with guide blocks that are slidably matched with the guide rods. The guide blocks are located at the bottom of the support frame.

[0012] The guide rods are installed on the support frame and are vertically arranged to guide the support frame to rise or fall smoothly along a predetermined path, providing the stability of the support frame. Through the close cooperation between the guide blocks and the guide rods, the swing of the support frame during movement can be effectively reduced, improving the stability and detection accuracy of the entire system.

[0013] Optionally, the driving gear is located at the top of the support frame, and the driving gear is connected to a first driving member.

[0014] The driving gear is located at the top of the support frame. Compared with being arranged in the middle, it can increase the rising height of the support frame.

[0015] Optionally, the top of the one-way screw is connected to a second driving member, and the moving support plate is provided with a limiting slot that is slidably matched with the support frame.

[0016] The characteristic of the one-way screw is that it can only rotate in one direction, which can prevent the moving support plate from sliding accidentally due to external forces during the detection process. The second driving member is used to drive the one-way screw to rotate. The function of the limiting slot is to limit the horizontal movement range of the moving support plate, ensuring that the moving support plate can only move in the vertical direction.

[0017] Optionally, the measuring assembly includes a moving frame and a measuring scale. A through hole is provided on the moving frame, and the through hole is slidably connected to the measuring scale. A fastening knob is threadedly connected to the side surface of the through hole.

[0018] The moving frame is used to carry the measuring scale. The measuring scale is marked with scales and can be used to directly read the displacement data in the horizontal direction. The function of the fastening knob is to fix the measuring scale after it is adjusted to the appropriate position to prevent it from moving during the measurement process.

[0019] Optionally, two measuring assemblies are symmetrically arranged on a single moving support plate.

[0020] The symmetrically arranged measuring assemblies can measure from both sides of the bridge pier simultaneously, which helps to obtain more accurate data and can detect whether the bridge pier has shifted in multiple directions.

[0021] Optionally, the measuring assembly is slidably connected to the moving support plate through a horizontal adjustment assembly. The horizontal adjustment assembly includes a bidirectional screw, and the two ends of the bidirectional screw are respectively threadedly connected to the measuring assemblies.

[0022] The horizontal adjustment assembly is used to adjust the positions of the two measuring assemblies in the horizontal direction. The bidirectional screw has two parts with opposite thread directions, usually at both ends of the same screw. When the bidirectional screw rotates, the nuts at both ends will move in opposite directions. In this design, the two ends of the bidirectional screw are respectively threadedly connected to the measuring assemblies. When the bidirectional screw rotates, the two measuring assemblies will move towards or away from each other simultaneously in the horizontal direction. Ensure that the distance between the two measuring assemblies remains consistent, thereby improving the detection accuracy and efficiency.

[0023] Optionally, the measuring assembly is provided with a sliding groove, and the sliding groove is slidably matched with the plate surface of the moving support plate.

[0024] The function of the sliding groove is to guide the movement of the measuring assembly in the horizontal direction and ensure that the measuring assembly does not deviate from the track during movement.

[0025] Beneficial effects

[0026] Adopting the technical solution provided by the present utility model, compared with the prior art, it has the following beneficial effects:

[0027] The technical solution provided by the present utility model is provided with a primary height adjustment assembly and a secondary height adjustment assembly. The secondary height adjustment assembly rises and falls on the basis of the primary height adjustment assembly, expanding the detection height range of the detection device. First, use the primary height adjustment assembly for rough adjustment, and then use the secondary height adjustment assembly for finer adjustment, so as to achieve the required detection accuracy and can adapt to the detection requirements of bridge piers of different heights.
