Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, and in particular relates to a bridge deck leveling mechanism for a steel structure bridge. Background Art

[0002] Bridges generally refer to structures erected on rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that are erected to cross mountain streams, poor geology, or meet other transportation needs to make passage more convenient. Bridges are generally composed of superstructures, substructures, supports, and ancillary structures. The superstructure is also called the bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers, and foundations; the supports are force transmission devices installed at the supporting locations of the bridge span structure and piers or abutments; the ancillary structures refer to the bridgehead slabs, conical slope protection, revetments, diversion projects, etc. Steel-structured bridges are bridges whose main load-bearing structures are made of steel, that is, steel structure bridges and steel bridges. During the construction of steel-structured bridges, the bridge deck is made of multiple steel plates spliced ​​together.

For details, please refer to the disclosed technology below; to solve the technical problems existing in this prior art, as disclosed in the background technology above, "when the above-mentioned design is used, although the detachable structure is reusable and has a wide range of applications, it is necessary to weld the first vertical plate and the second vertical plate to the steel plate during the leveling process, which makes it difficult to disassemble later and causes damage to the steel plate, resulting in poor use effect. At the same time, the connection is fixed by bolts, which reduces work efficiency." In terms of use, this problem is obviously a real problem that exists and is difficult to solve. In view of this, in order to solve this technical problem, a leveling component 3 and a moving component 4 are added to the application document.

[0026] More specifically:

[0027] like Figure 1-Figure 4 As shown:

[0028] A leveling assembly 3 is arranged on the reference steel plate 1, and the leveling assembly 3 includes first permanent magnets 301 arranged symmetrically on the reference steel plate 1, fixed seats 303 fixed on the tops of two groups of first permanent magnets 301, and sliding rods 304 fixed between the two groups of fixed seats 303 and arranged symmetrically. The surfaces of the two groups of sliding rods 304 are slidably connected with moving seats 305. The upper surface of the moving seat 305 is fixed with a jack 306 by bolts. A connecting plate 307 is fixed on the top of the jack 306. A second permanent magnet 311 is arranged below the connecting plate 307. The second permanent magnet 311 is provided at the bottom of the connecting plate 307. The upper surface of 11 is fixed with symmetrically arranged connecting pins 310, the internal thread of the movable seat 305 is connected with the fastening bolt 302, the surface of the movable seat 305 is provided with a movable hole adapted to the sliding rod 304, the movable seat 305 and the sliding rod 304 are slidably connected through the movable hole, one end of the fastening bolt 302 is in conflict with the surface of a group of sliding rods 304, the surface of the connecting plate 307 is provided with a sliding hole adapted to the connecting pin 310, the connecting pin 310 and the connecting plate 307 are slidably connected through the sliding hole, and the pressing end of the jack 306 is fixedly installed with a handle 308.

[0029] In this embodiment: the deck leveling mechanism of the steel structure bridge is placed at the position where leveling is required, and then the handle on the first permanent magnet 301 is turned to work, so that the first permanent magnet 301 is adsorbed on the surface of the reference steel plate 1, and the second permanent magnet 311 is placed on the steel plate 2 to be leveled, and the handle on the second permanent magnet 311 is turned over to work, and the second permanent magnet 311 is adsorbed on the surface of the steel plate 2 to be leveled, and then the jack 306 is continuously pressed by the handle 308, so that the jack 306 is continuously raised, and the connecting plate 307 is driven to rise, and the connecting plate 307 is moved upward ... The surface of the flat steel plate 2 is fixed, and the steel plate 2 to be leveled is lifted until the steel plate 2 to be leveled and the reference steel plate 1 are in the same horizontal plane. Then the leveled reference steel plate 1 and the steel plate 2 to be leveled are welded together and fixed. Through this operation, there is no need to fix the leveling mechanism by welding and bolting, thereby improving the flexibility and practicality of the operation, making disassembly more convenient, reducing the labor intensity of the staff, improving the leveling efficiency of the steel plate, and not causing damage to the steel plate. The use effect of this mechanism is improved, and the sliding movable seat 305 moves on the sliding rod 304, thereby driving the connecting plate 307 and the second permanent magnet 311 to move synchronously, so that the position can be adjusted without frequently changing the position of this mechanism, and then the sliding rod 304 is squeezed by rotating the fastening bolt 302, so that the movable seat 305 is fixed on the surface of the sliding rod 304, and the movable seat 305 is not easy to slide on the sliding rod 304.

[0030] It should be noted that the magnetic forces of the first permanent magnet 301 and the second permanent magnet 311 can be flexibly replaced according to the gravity of the steel plate.

[0031] Going further;

[0032] In an optional embodiment, a fixing ring 312 is fixed to the surface of the connecting pin 310 , a spring 313 is wound around the surface of the connecting pin 310 , and two ends of the spring 313 are fixedly connected to the fixing ring 312 and the connecting plate 307 , respectively.

[0033] In this embodiment: by setting the fixing ring 312 and the spring 313, the connectivity between the connecting pin 310 and the connecting plate 307 can be increased, avoiding the connecting pin 310 from sliding too much on the connecting plate 307 and colliding with the connecting plate 307 to cause damage to the second permanent magnet 311, thereby further improving the use effect of the device.

[0034] Going further;

[0035] In an optional embodiment, symmetrically arranged support rods 309 are fixed to the upper surface of the movable seat 305, and circular holes matching the support rods 309 are opened on the surface of the connecting plate 307, and the support rods 309 and the connecting plate 307 are slidably connected through the circular holes.

[0036] In this embodiment, when the connecting plate 307 moves upward, it also slides on the supporting rod 309 , thereby being able to improve the local limiting supporting effect on the middle position of the connecting plate 307 .

[0037] Further,

[0038] In an optional embodiment, a moving component 4 is installed on the leveling component 3, and the moving component 4 includes a connecting seat 401 fixed on the surface of two groups of sliding rods 304 in a symmetrical arrangement, a mounting plate 402 arranged below the connecting seat 401, and moving wheels 403 fixed on the lower surface of the mounting plate 402 in a symmetrical arrangement. The internal thread of the connecting seat 401 is connected to a threaded rod 405, and the bottom end of the threaded rod 405 is rotatably connected to the mounting plate 402 through a bearing, and telescopic rods 404 are fixed at the four corners between the connecting seat 401 and the mounting plate 402.

[0039] In this embodiment: when it is necessary to move the position of the device, the magnetism of the first permanent magnet 301 and the second permanent magnet 311 is turned off, and then the threaded rod 405 is rotated to drive the mounting plate 402 to move downward, and drive the moving wheel 403 to move downward. While the mounting plate 402 moves downward, the telescopic rod 404 is also driven to stretch. By setting the telescopic rod 404, the stability of the movement of the mounting plate 402 can be increased, until the moving wheel 403 contacts the bottom reference steel plate 1, and the first permanent magnet 301 is separated from the reference steel plate 1, so as to facilitate the pushing of the mechanism without manual handling, thereby reducing the labor intensity of the staff and further improving the use effect of the device.

[0040] The working principle and use process of the utility model are as follows: the deck leveling mechanism of the steel structure bridge is placed at the position where leveling is required, and then the handle on the first permanent magnet 301 is turned to work, so that the first permanent magnet 301 is adsorbed on the surface of the reference steel plate 1, and the second permanent magnet 311 is placed on the steel plate 2 to be leveled, and the handle on the second permanent magnet 311 is turned over to work, and the second permanent magnet 311 is adsorbed on the surface of the steel plate 2 to be leveled, and then the handle 308 is continuously pressed on the jack 306, so that the jack 306 is continuously raised, and the connecting plate 307 is driven to rise, and the connecting plate 307 is moved upward, and the connecting plate 307 slides on the connecting pin 310 until the top of the connecting plate 307 is aligned with the connecting pin 310. When the top of the pin 310 is blocked, the two sets of connecting pins 310 are driven to move upward synchronously, and the second permanent magnet 311 is driven to move upward by the connecting pin 310. Since the second permanent magnet 311 is adsorbed on the surface of the steel plate 2 to be leveled, the steel plate 2 to be leveled is lifted until the steel plate 2 to be leveled and the reference steel plate 1 are in the same horizontal plane. Subsequently, the reference steel plate 1 and the steel plate 2 to be leveled are welded together and fixed. Through this operation, there is no need to fix the leveling mechanism by welding or bolts, thereby improving the flexibility and practicality of the operation, making disassembly more convenient, reducing the labor intensity of the staff, improving the leveling efficiency of the steel plate, and not causing damage to the steel plate. The use effect of this mechanism is improved, and the sliding movable seat 305 is moved on the sliding rod 304 The movable seat 305 is not easy to slide on the sliding rod 304, and the connecting plate 307 moves upward, thereby driving the connecting plate 307 and the second permanent magnet 311 to move synchronously, so that the position can be adjusted, and there is no need to frequently change the position of this mechanism. Subsequently, the fastening bolt 302 is rotated to squeeze the sliding rod 304, so that the moving seat 305 is fixed on the surface of the sliding rod 304, and the moving seat 305 is not easy to slide on the sliding rod 304. While the connecting plate 307 moves upward, it slides on the support rod 309, so that the local limiting support effect of the middle position of the connecting plate 307 can be improved. At the same time, through the arrangement of the fixing ring 312 and the spring 313, the connectivity between the connecting pin 310 and the connecting plate 307 can be increased to prevent the connecting pin 310 from sliding too much on the connecting plate 307 and colliding with the connecting plate 307. The collision causes the second permanent magnet 311 to be damaged, further improving the use effect of the device. When the device needs to be moved, the magnetism of the first permanent magnet 301 and the second permanent magnet 311 is turned off, and then the threaded rod 405 is rotated to drive the mounting plate 402 to move down, and drive the moving wheel 403 to move down. While the mounting plate 402 moves down, it also drives the telescopic rod 404 to stretch. Through the setting of the telescopic rod 404, the stability of the movement of the mounting plate 402 can be increased, until the moving wheel 403 contacts the bottom reference steel plate 1, and separates the first permanent magnet 301 from the reference steel plate 1, thereby facilitating the pushing of the mechanism without manual transportation, reducing the labor intensity of the staff, and further improving the use effect of the device.
