[0018] Figure 2 It is a schematic structural diagram of the jacking mechanism and the adjustment module as shown in 1. Specific embodiments
[0019] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0020] As Figure 1 and Figure 2 shown, the present utility model discloses an embodiment of a bridge displacement and deviation correction device, which includes a translation mechanism, a jacking mechanism and an adjustment module 3. The translation mechanism is connected to the jacking mechanism and is used to drive the jacking mechanism to move horizontally. The driving end of the jacking mechanism is provided with a convex arc surface a, and the adjustment module 3 is provided with a concave arc surface adapted to the convex arc surface a. The adjustment module 3 can deflect relative to the jacking mechanism, and at least part of the convex arc surface a is in contact with the concave arc surface.
[0021] In this embodiment, the cooperation between the translation mechanism and the jacking mechanism can realize the jacking and moving support of the bridge A, or horizontal movement while jacking, so as to achieve flexible deviation correction. At the same time, by setting the convex arc surface a at the driving end of the jacking mechanism and the concave arc surface adapted to the convex arc surface a on the adjustment module 3, the adjustment module 3 can adaptively deflect according to the slope of the bottom of the bridge A, and at least part of the convex arc surface a is in contact with the concave arc surface, ensuring effective jacking or support of the jacking mechanism for the bridge A during the deviation correction process.
[0022] Specifically, the translation mechanism of this embodiment includes a base 11, a transverse driving rod 12, a longitudinal driving rod (not shown in the figure) and a universal rolling member 13. The base 11 is provided with a first accommodating cavity with an open top. The universal rolling member 13 is arranged in the first accommodating cavity and is in contact with the bottom of the jacking mechanism. The transverse driving rod 12 and the longitudinal driving rod are cross-arranged and are both connected to the base 11. The transverse driving rod 12 drives the jacking mechanism to move horizontally by adjusting the length extending into the first accommodating cavity, and the longitudinal driving rod drives the jacking mechanism to move horizontally by adjusting the length extending into the first accommodating cavity.
[0023] Among them, the universal rolling element 13 is a sphere, and the friction between it and the jacking mechanism is small, which can reduce the resistance of the jacking mechanism to translate. The lateral drive rods 12 are arranged in pairs on the left and right sides of the base 11 and are threadedly connected to the base 11. By synchronously and reversely rotating the lateral drive rods 12 on the left and right sides, the lateral drive rods 12 can push the jacking mechanism to move laterally on the universal rolling element 13, and at the same time play a role in laterally positioning the jacking mechanism; the longitudinal drive rods are arranged in pairs on the front and back sides of the base 11, and their extending directions are vertically crossed with those of the lateral drive rods 12. The longitudinal drive rods are threadedly connected to the base 11. By synchronously and reversely rotating the longitudinal drive rods on the left and right sides, the longitudinal drive rods can push the jacking mechanism to move longitudinally on the universal rolling element 13, and at the same time play a role in longitudinally positioning the jacking mechanism.
[0024] The jacking mechanism of this embodiment is preferably a hydraulic cylinder with large and stable driving force. The jacking mechanism of this embodiment specifically includes a cylinder block 21, a piston 22 and a protective sleeve 23. The piston 22 extends out from the top of the cylinder block 21. The convex arc surface a is arranged on the top surface of the piston 22. The bottom of the cylinder block 21 is sleeved in the protective sleeve 23. Between the cylinder block 21 and the universal rolling element 13, between the cylinder block 21 and the lateral drive rod 12, and between the cylinder block 21 and the longitudinal drive rod, they are all separated by the protective sleeve 23 to form protection for the cylinder block 21.
[0025] In addition, the translation mechanism of the present utility model can also be in other structural forms. For example, the translation mechanism includes a first base, a second base, a lateral drive rod, a longitudinal drive rod, a first rolling element and a second rolling element. The first base is provided with a first accommodation cavity with an open top. The first rolling elements are arranged in the first accommodation cavity. The jacking mechanism is arranged on the top of the first rolling elements; the second base is provided with a second accommodation cavity. The second rolling elements are arranged in the second accommodation cavity and are located below the first base. At the same time, the extending direction of the second rolling elements is perpendicular to the extending direction of the first rolling elements. The lateral drive rod is threadedly connected to the first base and extends axially towards the second rolling elements for driving the jacking mechanism to move laterally. The longitudinal drive rod is threadedly connected to the second base and extends axially towards the first rolling elements for driving the jacking mechanism to move longitudinally along with the first base. Among them, both the first rolling element and the second rolling element are cylindrical rollers.
[0026] Preferably, the adjustment module 3 is provided with a positioning support 311 for abutting against the jacking mechanism, or the jacking mechanism is provided with a positioning support 311 for abutting against the adjustment module 3. During the deflection of the adjustment module 3 relative to the piston 22, the positioning support 311 can prevent the adjustment module 3 from detaching from the piston 22 of the jacking mechanism or getting stuck with the piston 22, thus avoiding the occurrence of jacking failure.
[0027] The convex arc surface a in this embodiment is preferably a spherical arc surface. Regardless of the slope direction of the bottom surface of the bridge A, the adjustment module 3 of the jacking mechanism can freely deflect relative to the piston 22 to adapt to the jacking of the beam body inclined in different directions. The bridge displacement rectification device with this structure improves the adaptability and flexibility of the rectification device, and can be arbitrarily adjusted according to different beam bodies with different displacement deviations and different bottom surface inclination angles of the beam bodies.
[0028] When the top end face of the piston 22 is a spherical arc surface, the positioning support 311 is preferably arranged in a circumferential array along the convex arc surface a or the concave arc surface, so as to keep in contact with the top end face of the piston 22 when the adjustment module 3 deflects in different directions, and prevent the adjustment module 3 from detaching from the piston 22 of the jacking mechanism, resulting in jacking failure.
[0029] The convex arc surface a at the top of the piston 22 can also be a cylindrical surface. At this time, the adjustment module 3 can reciprocally swing relative to the piston 22 along the circular arc track of the cylindrical surface. At this time, when the jacking mechanism jacks the bridge AA, the inclination direction of the bottom surface of the beam body supported by the adjustment module 3 should be tangent to the cylindrical surface. When the top end face of the piston 22 is a cylindrical surface, the positioning support 311 is symmetrically arranged on both sides of the convex arc surface a or the concave arc surface to prevent the adjustment module 3 from detaching from the piston 22 of the jacking mechanism or getting stuck with the jacking mechanism, resulting in jacking failure.
[0030] In addition, the top end of the piston 22 can also be a structure in which a plane is combined with a cylindrical surface, and the cylindrical surface is symmetrically arranged on both sides of the plane, and there is a bow-shaped gap between the top end of the piston 22 and the concave arc surface of the adjustment module 3; or the top end of the piston 22 is a structure in which a plane is combined with a spherical arc surface, and the spherical arc surface is symmetrically arranged on both sides of the plane, and there is a bow-shaped gap between the top end of the piston 22 and the concave arc surface of the adjustment module 3. During the flipping process of the adjustment module 3, the cylindrical surface is always kept in contact with the concave arc surface, or the spherical arc surface is kept in contact with the concave arc surface.
[0031] The positioning support 311 unit includes a positioning pin and an elastic reset member (not shown in the figure). When the positioning pin is axially compressed, the elastic reset member is compressed, thereby changing the length of the entire positioning support unit to adapt to the height change in different orientations during the deflection of the adjustment module 3, and at the same time playing a role of supporting and positioning the adjustment module 3 to prevent the adjustment module 3 from getting stuck with the jacking mechanism.
[0032] The adjustment module 3 of this embodiment specifically includes a first support plate 31 and a second support plate 32. The top of the first support plate 31 is connected to the second support plate 32. The bottom of the first support plate 31 is provided with the concave arc surface. The second support plate 32 covers the first support plate 31, and a flipping drive part 321 for driving the adjustment module 3 to deflect is provided on the side surface of the second support plate 32. This flipping drive part 321 is a drive hole for inserting a drive lever, so as to facilitate adjusting the deflection direction of the adjustment module 3, so that the adjustment module 3 can better fit the bottom surface of the inclined bridge AA.
[0033] In addition, a cushion plate 4 is provided on the top surface of the second support plate 32. The cushion plate 4 is made of a flexible material to better fit the bottom surface of the beam body with a slope.
[0034] Whether it is the adjustment of the expansion joint size of the bridge A or the displacement correction of the beam body in different directions, the bridge displacement correction device of this embodiment can achieve fast and accurate adjustment through simple operations.
[0035] The above-disclosed is only a preferred embodiment of the present invention. Of course, it cannot be used to limit the scope of the rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
