Description

Technical Field

[0001] This utility model belongs to the field of beam straightening technology, specifically relating to a beam main beam installation and straightening device. Background Technology

[0002] A horizontal beam is a beam that is perpendicular to the longitudinal beams and is arranged along the short axis of the building. The main beam is the main beam arranged horizontally and plays a crucial role in supporting the building.

[0003] A related technology (announcement number CN206219997U) discloses a bridge box girder reinforcement and installation structure, including a solid asphalt layer, a reinforced concrete hollow layer, a steel box girder, an arched steel support frame, and a bridge pier. The upper surface of the bridge pier is provided with rivet holes. The steel box girder is installed on the upper surface of the bridge pier, and rivets at the bottom of the steel box girder are inserted into the rivet holes on the upper surface of the bridge pier. The reinforced concrete hollow layer is installed on the upper surface of the steel box girder, and a reinforced concrete hollow tube is provided in the middle of the reinforced concrete hollow layer. The solid asphalt layer is laid on the upper surface of the reinforced concrete hollow layer. A steel plate is provided at the connection between the bridge pier and the steel box girder. The arched steel support frame is installed on the support frame base on two adjacent bridge piers. The bottom end of the support plate is welded and fixed to the arched steel support frame, and the upper end of the support plate is welded to the steel plate.

[0004] This invention can improve the load-bearing capacity and stiffness of bridges to meet the requirements of heavy-duty transportation.

[0005] After the main beams are laid out, due to a combination of factors such as differences in the flatness of the construction site and the precision limitations of the installation equipment, the main beams are often difficult to achieve a perfectly level state immediately. Therefore, after the initial layout, it is necessary to manually operate relevant equipment to repeatedly adjust the position of the beams to ensure that the main beams meet the required installation accuracy. The precision and stability of this manual operation are limited, making it difficult to achieve a perfectly level placement of the main beams in one go. Each adjustment has a certain degree of error, requiring multiple attempts and corrections to gradually approach the ideal level state. This not only consumes a significant amount of time and labor costs but also increases the complexity of the construction process. Utility Model Content

[0006] To address the limitations of existing technologies in the precision and stability of manual installation and alignment of main beams, which makes it difficult to achieve precise horizontal placement of the main beam in one go, and which introduces errors with each adjustment, requiring multiple attempts and corrections to gradually approach the ideal horizontal state, this invention provides a main beam installation and alignment device that can achieve precise horizontal placement of the main beam in one go, avoiding manual errors caused by successive adjustments, saving time and labor costs associated with multiple adjustments, and simplifying the construction procedure for horizontal alignment and placement of the main beam. The specific technical solution is as follows:

[0007] A crossbeam main beam installation and correction device includes a mounting frame. A motor is fixedly mounted on the right side wall of the mounting frame. A motor is also mounted on the right side wall of the crossbeam. The output end of the motor is connected to one end of a first rotating shaft. A first bevel gear is mounted on the other end of the first rotating shaft. A correction component is provided at the mounting frame. The correction component includes a second rotating shaft that passes through and is rotatably connected to the top of the mounting frame from top to bottom. A second bevel gear is fixedly mounted on the bottom end of the second rotating shaft. A first rotating arm is fixedly mounted on the top end of the second rotating shaft. A third rotating shaft passes through and is rotatably connected to the bottom of the mounting frame from top to bottom. A third bevel gear is fixedly mounted on the top end of the third rotating shaft. A second rotating arm is fixedly mounted on the bottom end of the third rotating shaft.

[0008] The second bevel gear meshes with the first bevel gear, the third bevel gear meshes with the first bevel gear, the second shaft and the third shaft are located on the same vertical line, and the first rotating arm and the second rotating arm are centrally symmetrical with respect to the second shaft.

[0009] In the above technical solution, two first connecting arms are symmetrically installed on the lower surface of the first rotating arm, and two second connecting arms are symmetrically installed on the lower surface of the second rotating arm. Positioning components are installed on the two first connecting arms and the two second connecting arms, and the positioning components on the first connecting arms and the positioning components on the second connecting arms are arranged in a front-to-back correspondence.

[0010] In the above technical solution, the positioning component includes a base, a movable frame is slidably embedded in the inner cavity of the base, a rotating rod is rotatably arranged on the side of the movable frame away from the base, a limit wheel is fixedly installed on the rotating rod, multiple sets of positioning holes are opened through the movable frame, and each set of positioning holes is equidistantly arranged, a positioning rod is slidably inserted into the bottom end of the base, the positioning rod is embedded in the inner cavity of one of the positioning holes, a spring is sleeved on the positioning rod, and the two ends of the spring are fixedly connected to the positioning rod and the base respectively.

[0011] In the above technical solution, the edge of the limiting wheel is located outside the edge of the moving frame.

[0012] In the above technical solution, the bottom ends of the first connecting arm and the second connecting arm are located on the same horizontal line.

[0013] In the above technical solution, a first connecting seat is installed on the rear side of the mounting bracket, a first upright plate is vertically installed on the rear side of the first connecting seat, a second connecting seat is installed on the rear side of the first upright plate, a second upright plate is installed on the rear side of the second connecting seat, and the first upright plate and the second upright plate are arranged parallel to each other.

[0014] In the above technical solution, hooks are respectively installed at the top of the first upright plate and the second upright plate.

[0015] In the above technical solution, a crossbeam is positioned between the limiting wheels.

[0016] The present invention provides a crossbeam and main beam installation and correction device, which, compared with the prior art, has the following advantages:

[0017] I. The limitations of manual installation and alignment of the main beam in terms of precision and stability make it difficult to achieve a perfectly horizontal placement in one go. Each adjustment introduces errors, requiring multiple attempts and corrections to gradually approach the ideal horizontal state. This not only consumes significant time and labor costs but also increases construction complexity. This invention addresses these issues by using a synchronously rotating first and second rotating arm to simultaneously clamp the main beam in the center with four sets of alignment components, forcing it to be aligned horizontally. This achieves a one-time alignment and installation of the main beam, ensuring precise horizontal placement and avoiding manual errors caused by successive adjustments. It saves time and labor costs associated with multiple adjustments and simplifies the construction process for horizontal alignment of the main beam.

[0018] II. This utility model, through the cooperation of the first bevel gear, the second bevel gear and the third bevel gear, can synchronously drive the second bevel gear and the third bevel gear to rotate in relative directions, thereby realizing the synchronous rotation of the first rotating arm and the second rotating arm in relative directions. Moreover, the second rotating shaft and the third rotating shaft are located on the same vertical axis, which can realize that the first rotating arm and the second rotating arm rotate at the same angle, ensuring that the correction components at the first rotating arm and the second rotating arm always rotate at the same angle, thereby ensuring that the crossbeam and the main beam are in a horizontal state after the subsequent correction components perform horizontal correction on the crossbeam and the main beam.

[0019] Third, the first and second rotating arms in this utility model can always be symmetrically set with respect to the center of the second and third rotating axes after rotation, ensuring the accuracy of the position of the subsequent correction components.

[0020] IV. By setting the first connecting arm and the second connecting arm, this utility model can install the positioning components at the same height, ensuring that the four sets of positioning components act at the same height on the crossbeam and the main beam.

[0021] V. In this utility model, the extension length of the limiting wheel can be adjusted by means of the positioning rod, spring, moving frame and positioning hole, so as to flexibly adjust the distance between the front and rear positioning components. Thus, the distance between the two left or right positioning components can be adjusted separately to meet the side wall correction installation limit requirements of the trapezoidal crossbeam main beam.

[0022] In summary, this utility model can accurately achieve the horizontal placement of the main beam in one go, avoiding human error caused by repeated adjustments, saving time and labor costs of multiple adjustments, simplifying the construction procedure for horizontal correction and placement of the main beam, and can independently adjust the spacing between the two sets of positioning components on the left or the two sets on the right to meet the requirements of side wall correction and installation limit of the trapezoidal main beam.

Horizontal beam and main beam. Detailed Implementation

[0030] The following are specific implementation cases and appendices. Figures 1 to 6 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0031] See Figures 1 to 6 As shown, a crossbeam main beam installation and correction device includes a mounting frame 1. A motor 3 is fixedly mounted on the right side wall of the mounting frame 1. A motor 3 is also mounted on the right side wall of the crossbeam 2. The output end of the motor 3 is connected to one end of a first rotating shaft 4. A first bevel gear 5 is mounted on the other end of the first rotating shaft 4. The first rotating shaft 4 and the first bevel gear 5 are rotated from back to front by the activated motor 3. A correction component is provided at the mounting frame 1. The correction component includes a second rotating shaft 6 that runs from top to bottom through the top of the mounting frame 1 and is rotatably connected to it via a bearing. A second bevel gear 7 is fixedly mounted at the bottom end of the second rotating shaft 6. A first rotating arm 8 is fixedly mounted at the top end of the second rotating shaft 6. A third rotating shaft 9 runs from top to bottom through the bottom of the mounting frame 1 and is rotatably connected to it via a bearing. A third bevel gear 10 is fixedly installed at the top end of the three rotating shafts 9, and a second rotating arm 11 is fixedly installed at the bottom end of the third rotating shafts 9. The second bevel gear 7 is meshed with the first bevel gear 5, and the third bevel gear 10 is meshed with the first bevel gear 5. The second rotating shaft 6 and the third rotating shaft 9 are located on the same vertical line. The first rotating arm 8 and the second rotating arm 11 are centrally symmetrical with respect to the second rotating shaft 6. The motor 3, when turned on, causes the first rotating shaft 4 and the first bevel gear 5 to rotate from back to front, so that the second bevel gear 7 rotates clockwise while the third bevel gear 10 rotates counterclockwise. The clockwise rotation of the second bevel gear 7 causes the two sets of positioning components below the second rotating shaft 6 and the first rotating arm 8 to rotate synchronously.

[0032] Main references Figure 1 and Figure 2 As shown, two first connecting arms 12 are symmetrically mounted on the lower surface of the first rotating arm 8, and two second connecting arms 13 are symmetrically mounted on the lower surface of the second rotating arm 11. Positioning components are installed on the two first connecting arms 12 and the two second connecting arms 13, with the positioning components on the first connecting arms 12 and the second connecting arms 13 arranged correspondingly. The relative rotation of the first rotating arm 8 and the second rotating arm 11 causes the first connecting arms 12 and the second connecting arms 13 to rotate relative to each other. (See main reference...) Figure 3 , Figure 5 and Figure 6As shown, the positioning assembly includes a base 14, a movable frame 15 is slidably embedded in the inner cavity of the base 14, a rotating rod 16 is rotatably mounted on the side of the movable frame 15 away from the base 14 via a bearing, a limit wheel 17 is fixedly mounted on the rotating rod 16, multiple sets of positioning holes 18 are opened through the movable frame 15, and each set of positioning holes 18 is equidistantly arranged, a positioning rod 19 is slidably inserted into the bottom end of the base 14, the positioning rod 19 is embedded in the inner cavity of one of the positioning holes 18, a spring 20 is sleeved on the positioning rod 19, the two ends of the spring 20 are fixedly connected to the positioning rod 19 and the base 14 respectively, the counterclockwise rotating third bevel gear 10 causes the third rotating shaft 9 and the two sets of positioning assemblies below the second rotating arm 11 to rotate synchronously, thereby realizing that the two sets of positioning assemblies at the first rotating arm 8 and the two sets of positioning assemblies at the second rotating arm 11 gradually approach each other, that is, the limit wheel 17 gradually approaches each other.

[0033] In addition, please refer to the following for details. Figure 5 As shown, the edge of the limiting wheel 17 is located outside the edge of the moving frame 15 to ensure that when the limiting wheel 17 is in contact with the side wall of the main beam, the moving frame 15 will not be in contact with the side wall of the main beam, that is, the moving frame 15 will not interfere with the positioning of the limiting wheel 17 on the main beam; the bottom ends of the first connecting arm 12 and the second connecting arm 13 are located on the same horizontal line to ensure that the positioning components at the bottom ends of the first connecting arm 12 and the second connecting arm 13 are at the same height, so that the main beam can be positioned at the same height in the future.

[0034] See Figure 4 As shown, a first connecting seat 21 is installed on the rear side of the mounting frame 1, a first upright plate 22 is vertically installed on the rear side of the first connecting seat 21, a second connecting seat 23 is installed on the rear side of the first upright plate 22, and a second upright plate 24 is installed on the rear side of the second connecting seat 23. The first upright plate 22 and the second upright plate 24 are arranged parallel to each other. The first connecting seat 21, the first upright plate 22, the second connecting seat 23 and the second upright plate 24 can form a frame, so as to facilitate the connection and positioning of this equipment with other components and ensure the stability of this equipment during the subsequent straightening of the crossbeam and main beam.

[0035] The top of the first upright plate 22 and the second upright plate 24 are respectively equipped with hooks 25. The hooks 25 are suspended by the lifting device, which can realize the connection between this device and the lifting device. The lifting device is an existing equipment that can meet the lifting requirements. There is no limitation on its model.

[0036] The main beam 26 is positioned between the limiting wheels 17. The counterclockwise rotating third bevel gear 10 causes the third rotating shaft 9 and the two sets of positioning components below the second rotating arm 11 to rotate synchronously. This allows the two sets of positioning components at the first rotating arm 8 and the two sets of positioning components at the second rotating arm 11 to gradually approach each other until the limiting wheels 17 in the four sets of positioning components are in contact with the side wall of the main beam 26. As the first rotating arm 8 and the second rotating arm 11 continue to rotate, the four sets of limiting wheels 17 gradually straighten the main beam 26 to a horizontal position. At this time, the limiting wheels 17 can no longer move, thus achieving the horizontal straightening installation of the main beam 26.

[0037] It is worth noting that in this application, motor 3 is a commonly used self-locking motor with a lockable output end. When it stops, the output end can lock itself and will not rotate under external force. Motor 3 is a commonly used forward and reverse motor, and its output end can rotate in the forward or reverse direction according to the usage requirements. It is sufficient to meet the above usage requirements. The existing components will not be described in detail here.

[0038] The working principle of the crossbeam main beam installation and correction device in this embodiment is as follows:

[0039] The hook 25 is hoisted using a hoisting device, and the mounting frame 1 is positioned to maintain its position in the front-to-back direction. The motor 3 is turned on, causing the first rotating shaft 4 and the first bevel gear 5 to rotate from back to front. This causes the second bevel gear 7 to rotate clockwise, while the third bevel gear 10 rotates counterclockwise. The clockwise rotation of the second bevel gear 7 causes the second rotating shaft 6 and the two sets of positioning components below the first rotating arm 8 to rotate synchronously. The counterclockwise rotation of the third bevel gear 10 causes the third rotating shaft 9 and the two sets of positioning components below the second rotating arm 11 to rotate synchronously. This causes the two sets of positioning components at the first rotating arm 8 and the two sets of positioning components at the second rotating arm 11 to gradually approach each other until the limiting wheel 17 of the four sets of positioning components is in contact with the side wall of the main beam 26. As the first rotating arm 8 and the second rotating arm 11 continue to rotate, the four sets of limiting wheels 17 gradually straighten the main beam 26 to a horizontal position. At this point, the limiting wheel 17 can no longer move, thus achieving the horizontal straightening installation of the main beam 26.

[0040] When the main beam 26 is a trapezoidal shape that is wider on the left and narrower on the right or narrower on the left and wider on the right, the spacing between the limiting wheels 17 in the left and right positioning components needs to be adjusted: pull the spring 20 downward to make it disengage from the inner cavity of the corresponding positioning hole 18. At this time, the moving frame 15 loses the limitation of the positioning hole 18, the spring 20 is forced to stretch, and the moving frame 15 moves along the inner cavity of the seat 14. After adjusting the position of the limiting wheel 17, remove the tension on the positioning rod 19. Under the action of the spring 20, the positioning rod 19 is forced to insert into the inner cavity of the corresponding positioning hole 18, thereby realizing the positioning of the adjusted limiting wheel 17. In addition, in order to ensure the symmetry of the front and rear limiting wheels 17 at the first rotating arm 8 and the second rotating arm 11, the front and rear limiting wheels 17 need to be adjusted to the same displacement.

[0041] This invention can accurately achieve the horizontal placement of the main beam 26 in one go, avoiding human error caused by repeated adjustments, saving time and labor costs of multiple adjustments, simplifying the construction procedure for horizontal correction and placement of the main beam 26, and can independently adjust the spacing between the two sets of positioning components on the left or the two sets on the right to adapt to the side wall correction and installation limit requirements of the trapezoidal main beam 26.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
