Description

Technical Field

[0001] The invention relates to the field of settlement detection instrument installation equipment, in particular to a multi-point horizontal positioning device for road and bridge settlement detection. Background Art

[0002] As an important transportation infrastructure, bridges carry the weight of vehicles and pedestrians and are affected by the external environment for a long time. Their structure and functional performance will gradually change over time. Among them, bridge settlement is a common form of change and a major hidden danger in bridge operation. Bridge settlement will not only cause structural problems such as bridge deformation, cracks, displacement, etc., but also cause the overall instability of the bridge, causing serious accidents. In order to timely discover and deal with potential safety hazards and ensure the structural safety and normal use of bridges and roads, regular settlement detection can prevent structural damage caused by settlement, and can promptly discover any abnormal settlement problems, extend the service life of infrastructure, avoid further deterioration of problems, ensure the safety of vehicles and pedestrians, and improve the stability and safety of bridges and roads.

[0003] At present, a pressure differential static level is usually used for settlement detection of bridges. When in use, an installation position is selected on the surface of the pier, and a hole is drilled at the installation position to install the pressure differential static level. During installation, the pressure differential static level needs to be kept parallel to the ground to ensure the accuracy of the measurement results and avoid measurement errors caused by improper installation. At present, an electric drill is usually used for drilling holes during installation, and the hole spacing is determined by the installation holes of the level. Then, holes are drilled at fixed points on the surface of the pier. Each time a level is installed, a drilling point needs to be drilled, and the installation efficiency is slow. In addition, errors are prone to occur in the drilling point position, resulting in the hole not corresponding to the installation hole of the level after drilling, making it impossible to install the level, or the drilling is unstable, resulting in an inclination of the drilling angle. After the level is installed, the same inclination occurs, affecting the measurement results, and repeated drilling and installation are required. Summary of the invention

DETAILED DESCRIPTION

[0044] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0045] Embodiment 1

[0046] like Figure 1-3 , Figure 6 , Fig.13 and Fig.15 As shown, the present invention provides a multi-point horizontal positioning device for road and bridge settlement detection, including a drill bit 44 and a rotatable drill chuck 43 for clamping the drill bit 44, wherein four drill chucks 43 are provided, and the four drill chucks 43 are symmetrically distributed in a rectangular shape, and an adjustment device for controlling the position of the drill chuck 43 is installed on the inner side of the drill chuck 43;

[0047] The adjusting device includes a mounting frame and a telescopic plate rotatably connected to the four corners of the mounting frame and capable of swinging left and right. The mounting frame includes a mounting plate 1 at the front side and a back plate 2 at the rear side. The left and right sides of the front end of the mounting plate 1 are respectively fixedly connected with handles 27 for facilitating the user to use the device. The left and right ends of the mounting plate 1 and the back plate 2 are fixedly connected, and a sandwich is formed in the middle as an installation space. The drill chuck 43 is respectively installed at the telescopic end of the telescopic plate. The outer sides of the telescopic plate are respectively connected with support components for controlling the telescopic plate to be extended and retracted. The telescopic plate is composed of an adjusting plate 5 and a displacement plate 6 that are slidably connected to each other. One end of the adjusting plate 5 is hinged to the mounting plate 1, and the outer end of the displacement plate 6 is connected to the drill chuck 43. The support assembly controls the displacement plate 6 to slide on the surface of the adjustment plate 5 to form an effect of controlling the extension and retraction of the telescopic plate, which is used to adjust the installation range of the drill chuck 43. The installation position of the drill chuck 43 can be accurately adjusted by controlling the telescopic plate to swing left and right, so that the position of the drill chuck 43 is consistent with the position of the level installation hole. The front end of the installation frame is installed with a fixing structure for fixing the upper telescopic plate and the support assembly and the lower extension plate and the support assembly respectively. When in use, the four rotation points can be adjusted according to the installation holes at the four corners of the level according to the level as a standard to determine the placement position of the drill chuck 43. After the position of the drill chuck 43 is adjusted, it can be fixed by the fixing structure;

[0048] A gear ring 4 is rotatably connected to the center of the installation frame, and a sprocket transmission structure is respectively connected between the gear ring 4 and the drill chuck 43. When the gear ring 4 rotates, a structure in which multiple drill chucks 43 rotate synchronously can be formed. The synchronous rotation of the drill chuck 43 can drive four drill bits 44 to rotate, so that the device can be placed in a position parallel to the bridge pier, and pressure is applied to use four drill bits 44 to drill holes in the bridge pier at the same time, which is convenient for installing the level meter. Since the positions of the four drill bits 44 are adjusted according to the installation holes of the level meter as the standard, the holes punched can be completely aligned with the installation holes of the level meter, which meets the installation standards of the level meter, and avoids the situation in which the level meter cannot be installed due to the inability to align with the installation holes of the level meter after drilling, resulting in repeated drilling.

[0049] In order to ensure that the level meter remains horizontal with the ground during installation and to ensure the accuracy of detection, a level tube 51 is fixedly connected to the upper front end of the installation frame. The interior of the level tube 51 is filled with liquid and an air bubble is provided inside. A scale is provided on the surface. The liquid is a non-volatile liquid. The air bubble inside the level tube 51 can be observed during drilling. When the air bubble is in the middle position of the scale, the device is in a horizontal state to ensure that the device remains parallel to the ground while drilling, and to ensure that the level meter remains parallel to the ground after installation. Stabilizing disks 39 are respectively provided on the left and right sides of the rear end of the installation frame. The stabilizing disk 39 is horn-shaped, and the end of the stabilizing disk 39 with a larger diameter faces the side away from the installation frame. When drilling, the stabilizing disk 39 is in contact with the pier to support the device, so as to improve the stability of the device during drilling. An elastic component is connected between the stabilizing disk 39 and the installation frame. Under the action of the elastic component, after the stabilizing disk 39 contacts the pier, the device can still be displaced toward the pier to facilitate drilling and installation of the level meter.

[0050] The elastic component includes a support tube 40 and a support rod 42 that are coaxially slidably connected, a part of the support rod 42 is slidably connected inside the support tube 40, a support spring 41 is fixedly connected between the support rod 42 and the support tube 40, the other end of the support rod 42 is fixedly connected to the mounting frame, and the other end of the support tube 40 is fixedly connected to the stabilizing disk 39. When the stabilizing disk 39 fits the bridge pier and the device is pressed, the support rod 42 moves toward the inside of the support tube 40 and compresses the support spring 41. After the support spring 41 is compressed, it moves and drives the drill bit 44 to drill holes in the bridge pier. After completion, the stabilizing disk 39 is detached from the bridge pier, and the support spring 41 can push the stabilizing disk 39 to reset, which is convenient for users to use.

[0051] The sprocket transmission structure includes a double-row sprocket 10, a first single-row sprocket 9, a second single-row sprocket 11 and a chain 12. The hinge points of the first hinge rod 7 and the second hinge rod 50 are respectively coaxially connected to a double-row sprocket 10, the hinge point of the telescopic plate and the second hinge plate is coaxially connected to a second single-row sprocket 11, the hinge point of the telescopic plate and the first hinge plate is coaxially connected to a first single-row sprocket 9, the double-row sprocket 10 is respectively meshed with two chains 12, and the other ends of the chains 12 are respectively meshed with the corresponding first single-row sprocket 9 and the second single-row sprocket 11 , the drill chuck 43 is connected to the corresponding second single-row sprocket 11; the surface of the first single-row sprocket 9 is coaxially fixedly connected with a transmission gear 15, and multiple transmission gears 15 are meshed with the ring gear 4. A motor 3 is fixedly connected to the middle position of the installation frame, and the output end of the motor 3 is coaxially fixedly connected with the ring gear 4. When the motor 3 rotates, the ring gear 4 is controlled to rotate. When the ring gear 4 rotates, it can synchronously drive the transmission gear 15 to rotate by meshing with multiple transmission gears 15, and then drive the drill chuck 43 to rotate synchronously under the transmission of the double-row sprocket 10, the single-row sprocket and the chain 12 to perform drilling;

[0052] Furthermore, in order to ensure the drilling efficiency, reduce the wear of the drill bit 44, and avoid the drill bit 44 colliding with the bridge pier and causing the drill bit 44 to break, the drill chuck 43 is coaxially fixedly connected to the corresponding second single-row sprocket 11 with a buffer component, and the buffer component is used to provide a buffer effect when the drill bit 44 contacts the bridge pier, reduce the collision force, and protect the drill bit 44.

[0053] Furthermore, the buffer assembly includes a buffer cylinder 45 and a buffer rod 46 connected by a spline. The circumferential surface of the buffer rod 46 is provided with a plurality of first limiting grooves 48 distributed in an annular shape along the axial direction. The inner wall of the buffer cylinder 45 is respectively fixedly connected with a plurality of first limiting blocks distributed in an annular shape. When the buffer rod 46 is placed inside the buffer cylinder 45, the first limiting blocks are slidably matched with the first limiting grooves 48, so that the buffer rod 46 can drive the buffer cylinder 45 to rotate when rotating, and the buffer cylinder 45 can also move axially on the surface of the buffer rod 46. The other end is coaxially fixedly connected to the corresponding second single-row sprocket 11, and the other end of the buffer tube 45 is coaxially fixedly connected to the drill chuck 43. The surfaces of the buffer rods 46 extending out of the buffer tube 45 are respectively covered with buffer springs 47. When the drill bit 44 is pressurized, the buffer tube 45 will correspondingly displace and squeeze the buffer spring 47. While providing a buffering effect, the elastic force of the buffer spring 47 continuously applies pushing pressure to the drill bit 44, thereby protecting the drill bit 44 while drilling and avoiding the drill bit 44 from breaking.

When the telescopic plate is fixed, the first hinge plate can drive the displacement plate 6 to move up and down when it swings, thereby controlling the telescopic effect of the telescopic plate. When the telescopic plate swings left and right, it can drive the first hinge rod 7 and the second hinge rod 50 to swing synchronously, so as to facilitate the adjustment of the position of the drill chuck 43. When the first hinge plate is fixed, the adjustment plate 5 will drive the second hinge rod 50 to open synchronously outward when it swings, and drive the displacement plate 6 to move while opening, so as to facilitate the adjustment of the position of the drill bit 44 while the adjustment plate 5 swings, so as to facilitate the use of the user.

The connecting plate 18 cannot move forward and backward, so that the arc-shaped slider 29 and the connecting plate 18 form a whole, and then the first hinge plate and the adjusting plate 5 form a whole under the linkage action; when the connecting plate 18 cannot move, the first hinge plate cannot swing, and then in order to fix the adjusting plate 5, it also includes a fixing rod 34 connected to the inner end of the swing plate 53, the fixing rod 34 is fixedly connected to the mounting frame, and the inner end of the swing plate 53 is respectively coaxially fixedly connected with the first end face gear 35, and when the swing plate 53 swings The first end face gear 35 can be driven to rotate synchronously. The front side of the first end face gear 35 is coaxially provided with a second end face gear 36. The second end face gear 36 is splined with the fixing rod 34. The front end of the fixing rod 34 is respectively sleeved with a linkage plate 33. The other end of the linkage plate 33 is rotatably connected with the corresponding positioning bolt 30. When the positioning bolt 30 rotates, the positioning bolt 30 will be axially displaced under the action of the threaded connection with the arc sliding block 29. When the positioning bolt 30 moves, the second end face gear 36 can be pushed by the linkage plate 33 to move in the direction of the first end face gear 35. Since the fixing rod 34 is fixed, when the second end face gear 36 is splined with the fixing rod 34, the second end face gear 36 can only move axially on the surface of the fixing rod 34, but cannot rotate. When the second end face gear 36 is meshed with the first end face gear 35, the first end face gear 35 can be fixed, so that the swing plate 53 cannot swing. The swing plate 53 cannot swing, so that the arc sliding plate 20 cannot slide at the same time, thereby fixing the adjustment plate 5.

[0060] In order to improve the stability of the second end face gear 36 on the surface of the fixing rod 34, the surface of the fixing rod 34 between the second end face gear 36 and the linkage plate 33 is respectively sleeved with a return spring 38, one end of the return spring 38 is fixedly connected to the second end face gear 36, and the other end is fixedly connected to the fixing rod 34. The return spring 38 can support the second end face gear 36 and push the second end face gear 36 to mesh with the first end face gear 35, wherein the teeth of the first end face gear 35 and the second end face gear 36 that mesh with each other are respectively inner end teeth. The inclined surface inclined inwardly is retractable because the return spring 38 can be extended. Therefore, when the first end face gear 35 and the second end face gear 36 are meshed under the push of the return spring 38, the swing of the swing plate 53 is not affected. Under the support of the return spring 38, the second end face gear 36 will not slide arbitrarily on the surface of the fixing rod 34 and remain stable. When the linkage plate 33 blocks the second end face gear 36 and makes the second end face gear 36 unable to move, the first end face gear 35 can be fixed. In order to facilitate the linkage plate 33 to press against the second end face gear The gear 36 prevents the second end face gear 36 from being displaced, thereby forming a fixing effect on the first end face gear 35, and then fixing the adjustment plate 5 and the second hinge rod 50. The second end face gear 36 is fixedly connected to an end away from the first end face gear 35 with a mounting tube 37, which is sleeved on the surface of the fixing rod 34. The return spring 38 is arranged inside the mounting tube 37. The mounting tube 37 extends the pressure-bearing part of the second end face gear 36. The front end of the mounting tube 37 contacts the linkage plate 33. When the linkage plate 33 moves, the mounting tube 37 can be pushed to drive the second end face gear 36 to mesh with the first end face gear 35, and the first end face gear 35 is fixed. The return spring 38 forms a traction effect in the middle, which is conducive to the reset of the second end face gear 36; by rotating the positioning knob 31, the drill bits 44 at the four corners can be positioned to maintain the position of the drill bit 44, so that the user can drill holes according to the standard drilling angle and distance, which greatly facilitates the installation of the level, effectively improves the user's work efficiency, and avoids repeated construction.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
