Description

Technical Field

[0001] This utility model relates to the field of bridge bearing technology, specifically a bridge bearing displacement monitoring device. Background Technology

[0002] Bridge bearings are key force-transmitting components that connect the superstructure (such as beams) and substructure (such as piers and abutments) of a bridge. Their main function is to safely and reliably transfer the loads of the superstructure (including self-weight, live load, temperature stress, etc.) to the substructure. Bridge displacement monitoring is usually achieved by measuring the relative displacement between the upper and lower bearing plates.

[0006] Therefore, those skilled in the art have provided a bridge bearing displacement monitoring device to solve the above-mentioned problems. Utility Model Content

[0007] The purpose of this invention is to provide a bridge bearing displacement monitoring device to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A bridge bearing displacement monitoring device includes a pad stone and a bearing, and further includes: a multi-size clamping and fixing mechanism, an up-down and left-right adjustment mechanism, and a monitoring mechanism. The pad stone is equipped with the multi-size clamping and fixing mechanism for multi-size clamping and fixing, and the multi-size clamping and fixing mechanism is equipped with the up-down and left-right adjustment mechanism for left-right and up-down position adjustment. The monitoring mechanism is installed on the up-down and left-right adjustment mechanism, and the bearing is fixedly installed on the pad stone.

[0010] The multi-size clamping and fixing mechanism includes: a horizontal support component, a vertical limiting component, and a clamping force adjustment component. The horizontal support component is located on the upper side of the pad stone, the two vertical limiting components are installed on the left and right sides of the horizontal support component, and the clamping force adjustment component is installed on the vertical limiting component.

[0011] Furthermore, the lateral support assembly includes: a fixed horizontal plate, the fixed horizontal plate being located on the upper side of the pad stone, and a first strip-shaped opening being formed in the middle of the fixed horizontal plate;

[0012] Furthermore, the vertical limiting assembly includes: a rotating plate, a limiting plate, and an anti-slip pad. The two rotating plates are rotatably connected to the left and right sides of the fixed horizontal plate via a rotating shaft. The limiting plate is rotatably connected to the lower side of the rotating plate via a rotating shaft. The anti-slip pad is fixedly installed on the side wall of the limiting plate away from the rotating plate.

[0013] Furthermore, the clamping force adjustment assembly includes: a support assembly and a spacing adjustment assembly, wherein the support assembly is mounted on the rotating plate, and the spacing adjustment assembly is mounted on the support assembly;

[0014] Furthermore, the support assembly includes a support base and a rotating base, wherein the support base is rotatably connected to the fixed horizontal plate via a rotating shaft, and the rotating base is rotatably connected to the upper side of the rotating plate via a rotating shaft;

[0015] Furthermore, the adjusting assembly includes: a threaded rod, one end of which is rotatably connected to a support base, and the other end of which is threadedly connected to a rotating base away from the support base;

[0016] Furthermore, the up-down and left-right adjustment mechanism includes: a quick-fixing component and an up-down and left-right orientation adjustment component, wherein the quick-fixing component is mounted on the fixed horizontal plate, and the up-down and left-right orientation adjustment component is mounted on the quick-fixing component;

[0017] Furthermore, the quick-release fastening assembly includes: a quick-release threaded knob, which is slidably connected to the first strip-shaped opening;

[0018] Furthermore, the up / down / left / right orientation adjustment component includes: a first L-shaped support plate and a second L-shaped support plate. One end of the first L-shaped support plate is threaded to the left quick-release threaded knob, and one end of the second L-shaped support plate is threaded to the right quick-release threaded knob. The end of the first L-shaped support plate away from the left quick-release threaded knob is hinged to the end of the second L-shaped support plate away from the right quick-release threaded knob. The first L-shaped support plate and the second L-shaped support plate are provided with a plurality of second strip-shaped openings.

[0019] Furthermore, the monitoring mechanism includes a magnetostrictive displacement meter, which is fixedly mounted on the second strip-shaped opening by bolts and nuts.

[0020] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model places the fixing plate of the transverse support component of the multi-size clamping and fixing mechanism on the appropriate position of the pad stone. The rotation of the threaded rod causes the rotating seat of the support component to move on the threaded rod. When the rotating seat moves away from the support seat, the rotating seat moves on the threaded rod and drives the rotating plate to rotate. The rotation of the rotating plate drives the limiting plate to rotate. The limiting plate rotates to the side wall position of the pad stone and stops. The pad stone is clamped by the limiting plate and the rotating plate, so that the fixing plate is fixed on the upper side of the pad stone, which is conducive to quickly fixing the equipment on pad stones of different sizes.

[0021] 2. By loosening the quick-release threaded knobs of the quick-release fixing components of the up / down and left / right adjustment mechanism, and simultaneously moving the two quick-release threaded knobs to the left or right, the first L-shaped support plate and the second L-shaped support plate move to the left or right simultaneously, thereby changing the left / right orientation of the magnetostrictive displacement gauge. This ensures that the detection end of the magnetostrictive displacement gauge on the first or second L-shaped support plate is in close contact with the upper plate of the support. The displacement of the bridge is measured by detecting the displacement of the upper plate. Moving the two quick-release threaded knobs in the same or opposite directions rotates the first and second L-shaped support plates, causing the hinge position of the first and second L-shaped support plates to move up and down, thereby changing the up / down orientation of the magnetostrictive displacement gauge. Tightening the two quick-release threaded knobs causes them to abut against the sides of the fixing cross plate, respectively, thus fixing the first and second L-shaped support plates. This facilitates quick adjustment of the up / down and left / right orientation of the magnetostrictive displacement gauge. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0029] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-4 A bridge bearing displacement monitoring device includes a pad stone 1 and a bearing 2, and further includes: a multi-size clamping and fixing mechanism 3, an up-down and left-right adjustment mechanism 4, and a monitoring mechanism 5. The pad stone 1 is equipped with the multi-size clamping and fixing mechanism 3 for multi-size clamping and fixing, and the multi-size clamping and fixing mechanism 3 is equipped with the up-down and left-right adjustment mechanism 4 for left-right and up-down position adjustment. The monitoring mechanism 5 is installed on the up-down and left-right adjustment mechanism 4, and the bearing 2 is fixedly installed on the pad stone 1.

[0030] The multi-size clamping and fixing mechanism 3 includes: a horizontal support component, a vertical limiting component, and a clamping force adjustment component. The horizontal support component is located on the upper side of the pad stone 1, the two vertical limiting components are installed on the left and right sides of the horizontal support component, and the clamping force adjustment component is installed on the vertical limiting component.

[0031] The transverse support assembly includes: a fixed horizontal plate 31, which is located on the upper side of the pad stone 1, and a first strip-shaped opening 32 is provided on the middle side of the fixed horizontal plate 31.

[0032] When installing the equipment, place the fixing plate 31 of the transverse support assembly of the multi-size clamping and fixing mechanism 3 on the appropriate position of the pad stone 1.

[0033] The vertical limiting assembly includes a rotating plate 33, a limiting plate 34, and an anti-slip pad 35. The two rotating plates 33 are rotatably connected to the left and right sides of the fixed horizontal plate 31 via a rotating shaft. The limiting plate 34 is rotatably connected to the lower side of the rotating plate 33 via a rotating shaft. The anti-slip pad 35 is fixedly installed on the side wall of the limiting plate 34 away from the rotating plate 33.

[0034] The anti-slip pad 35 of the vertical limiting component is pressed against the side wall of the pad stone 1. The rotating plate 33 rotates, causing the limiting plate 34 to rotate. The limiting plate 34 rotates to the side wall position of the pad stone 1 and stops. The pad stone 1 is clamped by the limiting plate 34 and the rotating plate 33, so that the fixing plate 31 is fixed on the upper side of the pad stone 1.

[0035] The clamping force adjustment assembly includes a support assembly and a spacing adjustment assembly. The support assembly is mounted on the rotating plate 33, and the spacing adjustment assembly is mounted on the support assembly.

[0036] The support assembly includes a support base 36 and a rotating base 37. The support base 36 is rotatably connected to the fixed horizontal plate 31 via a rotating shaft, and the rotating base 37 is rotatably connected to the upper side of the rotating plate 33 via a rotating shaft.

[0037] The adjustment assembly includes a threaded rod 38, one end of which is rotatably connected to a support 36, and the other end of which is threaded to a rotating seat 37.

[0038] The threaded rod 38 of the rotating adjustment assembly rotates, causing the rotating seat 37 of the support assembly to move on the threaded rod 38. When the rotating seat 37 moves away from the support seat 36, the rotating seat 37 moves on the threaded rod 38, causing the rotating plate 33 to rotate. The support seat 36 is used to support the threaded rod 38.

[0039] Example 2: In some embodiments, such as Figures 1-4 In a preferred embodiment of the present invention, the up-down and left-right adjustment mechanism 4 includes: a quick-fixing component and an up-down and left-right orientation adjustment component. The quick-fixing component is mounted on the fixed horizontal plate 31, and the up-down and left-right orientation adjustment component is mounted on the quick-fixing component.

[0040] The quick-release fastening assembly includes a quick-release threaded knob 41, which is slidably connected to the first strip-shaped opening 32.

[0041] The up / down / left / right orientation adjustment assembly includes: a first L-shaped support plate 42 and a second L-shaped support plate 43. One end of the first L-shaped support plate 42 is threaded to the left quick-release threaded knob 41, and one end of the second L-shaped support plate 43 is threaded to the right quick-release threaded knob 41. The end of the first L-shaped support plate 42 away from the left quick-release threaded knob 41 is hinged to the end of the second L-shaped support plate 43 away from the right quick-release threaded knob 41. The first L-shaped support plate 42 and the second L-shaped support plate 43 are provided with a plurality of second strip-shaped openings 44.

[0042] The monitoring mechanism 5 includes a magnetostrictive displacement meter 51, which is fixedly installed on the second strip-shaped opening 44 by bolts and nuts.

[0043] Loosen the quick-release screw knob 41 of the quick-release fixing component of the up / down / left / right adjustment mechanism 4. Simultaneously move both quick-release screw knobs 41 to the left or right, and the first L-shaped support plate 42 and the second L-shaped support plate 43 will move to the left or right at the same time, thereby changing the left / right orientation of the magnetostrictive displacement gauge 51. This will cause the detection end of the magnetostrictive displacement gauge 51 on the first L-shaped support plate 42 or the second L-shaped support plate 43 to be in close contact with the upper seat plate of the support 2. The displacement of the bridge is measured by detecting the displacement of the upper seat plate. Moving the two quick-release screw knobs 41 in the same or opposite direction will cause the first L-shaped support plate to move to the left or right. Rotating the first L-shaped support plate 42 and the second L-shaped support plate 43 causes the hinge position of the first L-shaped support plate 42 and the second L-shaped support plate 43 to move up and down, thereby changing the up and down position of the magnetostrictive displacement meter 51. The range of the up and down movement is relatively large. Tightening the two quick-release threaded knobs 41 causes the two quick-release threaded knobs 41 to abut against the two sides of the fixed horizontal plate 31 with the first L-shaped support plate 42 and the second L-shaped support plate 43 respectively, thereby fixing the first L-shaped support plate 42 and the second L-shaped support plate 43. This facilitates the quick adjustment of the up and down and left and right positions of the magnetostrictive displacement meter 51.

[0044] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
