Description

Technical Field

[0001] This invention relates to the field of bridge construction, specifically a support adjustment device for bridge construction. Background Technology

[0002] Bridges generally refer to structures erected over rivers, lakes, and seas to facilitate the passage of vehicles and pedestrians. To adapt to the rapidly developing modern transportation industry, the term "bridge" has also come to refer to structures built across mountains, streams, adverse geological conditions, or to meet other transportation needs, making travel more convenient. A bridge typically consists of a superstructure, substructure, supports, and ancillary structures. The superstructure, also known as the bridge span structure, is the main structure that crosses obstacles. The substructure includes abutments, piers, and foundations. Supports are force-transmitting devices installed at the points where the bridge span structure supports the piers or abutments. Ancillary structures include approach slabs, tapered slopes, revetments, and diversion works. Bridges greatly facilitate people's travel and improve travel efficiency. Since bridges are formed by connecting multiple bridge sections, bridge construction support devices are often used during construction and repair to ensure bridge stability and prevent collapse due to external vibrations. Bridge support devices are a commonly used auxiliary tool in bridge construction, providing support and protection for the structure. Existing bridge construction support devices provide good support for the bridge structure.

[0003] However, most of the support devices currently available for bridge construction are directly fixed to the ground. The position and spacing after installation can be easily adjusted, but this makes operation relatively inconvenient. Summary of the Invention

[0004] To address the existing problems, the present invention provides a support adjustment device for bridge construction, which, when used in conjunction with other devices, can effectively solve the problems mentioned in the background art.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A bridge construction support adjustment device includes a support mechanism comprising: a bridge deck support frame, a longitudinal support frame, and a scissor support mechanism. A transverse rotating frame is installed in the middle of the longitudinal support frame. The scissor support mechanism includes: two scissor brackets connected to a central rotating shaft between the two scissor brackets and the transverse rotating frame. A support storage groove is provided inside the longitudinal support frame. Lifting lugs are installed on the two scissor brackets near the support storage groove. The interior of the support storage groove is connected to the lifting lugs. A lifting hydraulic cylinder is connected between the lifting lugs. An embedded groove is formed on the lower surface of the bridge plate support frame above the scissor bracket. A rolling groove is formed on the inner side wall of the embedded groove. A sliding roller is connected to the upper end of the scissor bracket inside the rolling groove. Lifting mechanisms are installed at both ends of the embedded groove on the lower surface of the bridge plate support frame. A hydraulic cylinder is installed inside the lifting mechanism. A bridge plate roller is installed at the upper end of the output shaft of the hydraulic cylinder. A baffle is provided above the bridge plate roller on the inner side wall of the lifting mechanism.

[0007] As a further embodiment of the present invention: a bottom guide rail is provided below the longitudinal support frame, and a bottom groove is formed on the lower surface of the longitudinal support frame outside the bottom guide rail. Support swing arms are connected to both ends of the bottom guide rail, and a reinforcing rod is connected to the free end of the support swing arm. A central rod is installed at the end of the bottom guide rail.

[0008] As a further embodiment of the present invention: a lead screw through hole is provided above the bottom slide groove inside the longitudinal support frame, a bidirectional lead screw is installed inside the lead screw through hole, and an adjustable pitch motor is installed at one end of the bidirectional lead screw above the bottom guide rail.

[0009] As a further embodiment of the present invention: a side baffle is installed on the outer side of the upper surface of the bridge plate support frame.

[0010] As a further embodiment of the present invention: the scissor bracket is rotatably connected to the transverse rotating frame via the central rotating shaft, and the output shaft of the lifting hydraulic cylinder is rotatably connected to the lifting ear plate.

[0011] As a further embodiment of the present invention: the scissor bracket is slidably connected to the rolling groove via the sliding roller, and the transverse rotating frame is fixedly connected to the longitudinal support frame.

[0012] As a further embodiment of the present invention: an elastic rotating shaft is installed between the baffle and the lifting mechanism, and a rotating lug is connected to the outer side of the bridge plate roller located on the output shaft of the hydraulic cylinder.

[0013] As a further embodiment of the present invention: a positioning screw is connected between the support swing arm and the bottom guide rail, and the longitudinal support frame is slidably connected to the bottom guide rail through the bottom groove.

[0014] As a further embodiment of the present invention: the bidirectional lead screw is rotatably connected to the lead screw through hole, and the adjustable pitch motor is fixedly connected to the bottom guide rail.

[0015] As a further embodiment of the present invention: the side baffle is fixedly connected to the bridge plate support frame, and the lifting hydraulic cylinder is fixedly connected to the longitudinal support frame.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. After disconnecting the bolts fixing the support swing arm at the end of the bottom guide rail, control the support swing arm to rotate as a whole and then fix it with bolts. Position the center rod on the bottom guide rail to the ground. After passing the reinforcing rod through the free end of the support swing arm, position and fix it to the ground. This allows for convenient control of the positioning and dismantling of the entire support mechanism.

[0018] 2. By starting the adjustable motor, the bidirectional lead screw is controlled to rotate as a whole. The rotating bidirectional lead screw will synchronously drive the bottom sliding grooves inside the two longitudinal support frames to mesh and rotate. The lead screw holes at the lower end of the longitudinal support frames slide above the bottom guide rail, so that the distance between the two longitudinal support frames can be adjusted to facilitate the support of bridge decks of different widths.

[0019] 3. The extension rod of the lifting hydraulic cylinder pushes the lifting ear plate on the outside of the scissor bracket, so that the two scissor brackets rotate in the transverse rotating frame through the central pivot in the middle. At the same time, the sliding roller at the upper end of the scissor bracket will slide inward in the rolling groove on the inner side wall of the embedded groove. Then the entire scissor support mechanism will control the bridge deck support frame to lift upward, which can control the raising of the spliced ​​bridge deck and the installation of the bridge pier position.

[0020] 4. By using a hydraulic cylinder to push the bridge plate rollers upward as a whole, and controlling the bridge plate rollers to push the baffle to swing, the bridge plate rollers come into contact with the lower surface of the spliced ​​bridge deck. This facilitates the connection between the lifting mechanism and the bridge deck, and also facilitates the movement of the bridge deck on the bridge plate rollers for installation and splicing.

A lifting hydraulic cylinder 401 is connected between the inside of the support storage groove 405 and the lifting ear plate 602. The output shaft of 01 is rotatably connected to the lifting ear plate 602. The lower surface of the bridge plate support frame 2 is provided with an embedded groove 201 above the scissor bracket 601. The inner side wall of the embedded groove 201 is provided with a rolling groove 203. The scissor bracket 601 is slidably connected to the rolling groove 203 through a sliding roller 604. The upper end of the scissor bracket 601 is connected to the sliding roller 604 inside the rolling groove 203. Both ends of the embedded groove 201 are equipped with lifting mechanisms 3 on the lower surface of the bridge plate support frame 2. The lifting mechanism 3 is equipped with a hydraulic cylinder 301. The upper end of the output shaft of the hydraulic cylinder 301 is equipped with a bridge plate roller 302. The outer side of the bridge plate roller 302 is connected to the output shaft of the hydraulic cylinder 301 with a rotating ear plate. A baffle 303 is provided above the bridge plate roller 302 on the inner side wall of the lifting mechanism 3. An elastic rotating shaft is installed between the baffle 303 and the lifting mechanism 3.

[0031] like Figure 2-6 As shown, in this embodiment, a bottom guide rail 5 is provided below the longitudinal support frame 4. A lifting hydraulic cylinder 401 is fixedly connected to the longitudinal support frame 4. A bottom groove 403 is provided on the lower surface of the longitudinal support frame 4 outside the bottom guide rail 5. The longitudinal support frame 4 is slidably connected to the bottom guide rail 5 through the bottom groove 403. Supporting swing arms 501 are connected to both ends of the bottom guide rail 5. A positioning screw is connected between the supporting swing arms 501 and the bottom guide rail 5. A reinforcing rod 502 is connected to the free end of the supporting swing arms 501. A central insert rod 503 is installed at the end of the guide rail 5. A lead screw through hole 404 is opened inside the longitudinal support frame 4 above the bottom slide groove 403. A bidirectional lead screw 8 is installed inside the lead screw through hole 404. The bidirectional lead screw 8 is meshed and rotatably connected with the lead screw through hole 404. An adjustable pitch motor 7 is installed above the bottom guide rail 5 at one end of the bidirectional lead screw 8. The adjustable pitch motor 7 is fixedly connected to the bottom guide rail 5. A side baffle 202 is installed on the outer side of the upper surface of the bridge plate support frame 2. The side baffle 202 is fixedly connected to the bridge plate support frame 2.

[0032] The working principle of this invention is as follows: During bridge installation, a multi-segment splicing installation is employed. After the bridge deck at the pier end is fixed, the support mechanism 1 is arranged as a whole on one side of the pier's extension direction. The bridge deck support frame 2 is positioned perpendicular to the transverse tangent of the bridge deck. After disconnecting the bolts fixing the support swing arm 501 at the end of the bottom guide rail 5, the support swing arm 501 is rotated and then fixed with bolts. The center insert rod 503 on the bottom guide rail 5 is positioned with the ground, and then the reinforcing insert rod 502 is passed through the free end of the support swing arm 501. After positioning and fixing to the ground, the spacing between the two sets of longitudinal support frames 4 is controlled by the required width of the bridge deck to be spliced. The adjustment motor 7 is activated to control the rotation of the bidirectional lead screw 8. The rotating bidirectional lead screw 8 synchronously drives the bottom sliding grooves 403 inside the two longitudinal support frames 4 to engage and rotate. Simultaneously, the lead screw through holes 404 at the lower end of the longitudinal support frames 4 slide above the bottom guide rail 5, increasing the distance between the two longitudinal support frames 4. When the adjustment motor 7 is controlled to rotate in the opposite direction, the distance between the two longitudinal support frames 4 decreases, thus aligning the bridge deck to be spliced. The bridge deck support 2 is placed above the bridge deck support frame 2. A lifting hydraulic cylinder 401 installed inside the longitudinal support frame 4 operates, causing the telescopic rod of the lifting hydraulic cylinder 401 to push the lifting ear plate 602 on the outer side of the scissor bracket 601. This causes the two scissor brackets 601 to rotate within the transverse rotating frame 402 via the central pivot 603. Simultaneously, the sliding roller 604 at the upper end of the scissor bracket 601 slides inward in the rolling groove 203 on the inner wall of the embedded groove 201. The entire scissor support mechanism 6 then controls the bridge deck support frame 2 to lift upward. After lifting, the bridge deck support 2... Once the bridge deck is parallel to the end of the pier, the side of the bridge deck closest to the pier can be lifted. The hydraulic cylinder 301 pushes the bridge plate roller 302 upward, and the bridge plate roller 302 pushes the baffle 303 to swing, so that the bridge plate roller 302 contacts the lower surface of the spliced ​​bridge deck. Then, one end of the spliced ​​bridge deck is lifted. The lifting mechanism on the bridge is connected to one end of the bridge deck. Then, the lifting mechanism 3 at the other end is used to lift the bridge deck and connect it to the lifting mechanism. After the bridge deck is spliced, the support mechanism 1 can be completely removed and installed in the subsequent position.
