Description

Technical Field

[0001] The invention relates to a bridge reconstruction and expansion installation device, belonging to the technical field of highway reconstruction and expansion. Background Art

[0002] As urban traffic continues to rise, road renovation and expansion projects have become an important means of improving road capacity. In bridge expansion construction, portal frame structures are often used as piers, in conjunction with the erection of upper precast beams to complete the construction of new bridges. Currently, mainstream bridge-building machines mostly use a structural design that combines dual parallel drive modules with a lifting hanger. Its operation process is as follows: First, the bridge-building machine is shifted so that the front legs are located on the top surface of the target bridge pier; then, the precast beam is transported to the initial position below the bridge-building machine by a transport vehicle; then, the lifting hanger is lowered and the precast beam is secured using the fastening device on the hanger; then, the precast beam is lifted vertically and horizontally moved to the installation point directly above it via the parallel drive module; finally, it is slowly lowered to complete the installation operation.

[0003] However, in actual construction, when transport vehicles deliver precast beams to the base of the bridge-erecting crane, the beams are prone to angular deviation or misalignment between the beams and the hangers. This deviation not only causes damage to the beams during the hanger's lowering and docking process, directly impacting the quality of the bridge expansion project, but also requires operators to repeatedly adjust the vehicle's position to ensure safe installation. This often requires reversing, especially for inexperienced drivers, significantly extending the precast beam installation cycle. Furthermore, these repeated adjustments can create subtle, imperceptible angles or misalignments, further increasing construction risks. Summary of the Invention

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0037] Example 1: Figures 1-6 As shown, a bridge renovation and expansion installation device is provided, comprising: a lifting rope 11 connected to the overhead crane on the bridge erection machine, a mounting column 1 detachably connected to the lower end of the lifting rope 11, a mounting support for components such as a mounting plate 2 is provided through the mounting column 1, the mounting plate 2 is movably set on the lower end of the mounting column 1, and a connecting column 23 is rotatably mounted on the middle part of the lower end of the mounting plate 2, a mounting support for a ring gear 24 is provided through the connecting column 23, and the ring gear 24 is then set on the outer end of the connecting column 23, and the connecting column 23 is rotated by the ring gear 24;

[0038] The transmission gear 22 is meshed with the front end of the ring gear 24, and the ring gear 24 is driven to rotate through the transmission gear 22. The fixed part of the third driving device located at the front side of the mounting column 1 and having an output shaft passing through the mounting plate 2 and connected to the transmission gear 22 is installed on the upper end of the mounting plate 2. The transmission gear 22 is driven to rotate through the third driving device. The third driving device can adopt a third motor 21. The damping gear 25 rotatably connected to the lower end of the mounting plate 2 is then meshed with the rear end of the ring gear 24. The rotation of the ring gear 24 is damped through the damping gear 25.

[0039] The middle part of the upper end of the rectangular tube 3 is connected to the other end of the connecting column 23, and a mounting carrier is provided for components such as the screw rod 7 through the rectangular tube 3, and the two function boxes 4 are respectively slidably connected to the left and right ends of the rectangular tube 3, and a mounting carrier is provided for components such as the bidirectional screw 48 through the function box 4. Then, the two bidirectional screws 48 are respectively rotatably connected to the two function boxes 4, and the corresponding two movable plates 42 are moved relative to each other through the bidirectional screw 48. The fixed parts of the second driving device connected to the two output shafts and the bidirectional screw 48 are respectively installed on the rear ends of the two function boxes 4, and the bidirectional screw 48 is driven to rotate by the second driving device. The second driving device can adopt a fourth motor 41;

[0040] The lower end surface of the function box 4 is recessed upward to form two through holes 49 extending to the inner wall of the function box 4. The through holes 49 provide movement space for the movement of the movable plate 42. The two movable plates 42 that pass through the two through holes 49 are symmetrically slidably connected in the function box 4, and the bidirectional screw 48 that is threadedly connected to the two movable plates 42 passes through the two movable plates 42. The movable plate 42 provides an installation carrier for components such as the splint 43. The two located on the lower side of the function box 4 are respectively installed on the inner ends of the two movable plates 42. The two splints 43 are used in combination to clamp the prefabricated beam. The two guide rods 47 located on the left and right sides of the bidirectional screw 48 are symmetrically arranged in the function box 4. The guide rods 47 that are slidably connected to the two movable plates 42 pass through the two movable plates 42. The two guide rods 47 are used in combination to guide the movement of the two movable plates 42.

[0041] The two clamping blocks 44 are respectively attached to the lower ends of the two clamping plates 43. The two clamping blocks 44 are used in conjunction with each other to lift the precast beam on the one hand and clamp the lower side wall of the precast beam on the other hand, and the movable part passes through the movable plate 42 and the fixed part of the telescopic device connected to the clamping blocks 44 is set on the outward end of the movable plate 42. The telescopic device drives the clamping blocks 44 to move. The telescopic device can use an electric push rod 46, and then the two round rods 45 on the left and right sides of the telescopic device are symmetrically installed on the outward ends of the clamping blocks 44, and the round rods 45 slidably connected to the movable plate 42 pass through the movable plate 42. The two round rods 45 are used in conjunction with each other to guide the movement of the clamping blocks 44. Protective parts are set at the inner ends of the clamping plates 43 and the inner ends of the clamping blocks 44. The protective parts achieve protection performance, and the protective parts can use rubber pads.

[0042] The connecting plate 6 passing through the rectangular tube 3 is installed between the two functional boxes 4. The two functional boxes 4 are connected through the connecting plate 6, and the screw rod 7 passing through the connecting plate 6 and connected to the connecting plate 6 through a ball nut pair is rotatably connected to the rectangular tube 3. The connecting plate 6 moves back and forth through the screw rod 7. The fixed part of the first driving device connected to the output shaft and the screw rod 7 is then installed on the front end of the rectangular tube 3. The screw rod 7 is driven to rotate through the first driving device. The first driving device can adopt a first motor 5, and the two guide rods 71 ​​located on the left and right sides of the screw rod 7 are symmetrically installed inside the rectangular tube 3, and the two guide rods 71 ​​slidingly connected to the guide rod 71 both pass through the connecting plate 6. The two guide rods 71 ​​are used together to guide the movement of the connecting plate 6.

[0043] When in use, first move the bridge-building machine and move the front support leg of the bridge-building machine to the corresponding pier top, then use the vehicle to transport the precast beam to the initial position, and then make the overhead crane on the bridge-building machine lower the lifting rope 11. If the two movable plates 42 and the precast beam are in a front-to-back misalignment state, first start the first motor 5 to drive the screw rod 7 to rotate. Since the screw rod 7 and the connecting plate 6 are connected by a ball nut pair, the rotation of the screw rod 7 will cause the connecting plate 6 to move along the rectangular tube 3, and then the two functional boxes 4 will move, thereby causing the corresponding two movable plates 42 and other components to move, and then the two clamping plates 43 on the corresponding side to be located on the opposite sides of the precast beam, so as to adjust the front and rear positions of the functional box 4, effectively reducing the probability of damage to the precast beam due to factors such as misalignment between the precast beam and the movable plate 42, and effectively ensuring the quality and efficiency of the bridge expansion.

[0044] If the precast beam and the rectangular tube 3 are at an angle, the third motor 21 is started first to drive the transmission gear 22 to rotate. Since the transmission gear 22 and the ring gear 24 are meshed with each other, the rotation of the transmission gear 22 will cause the ring gear 24 to rotate, thereby rotating the connecting column 23, thereby rotating the rectangular tube 3 and other components, thereby making the rectangular tube 3 parallel to the precast beam, thereby adjusting the angle of the rectangular tube 3 and other components, effectively reducing the probability of damage to the precast beam due to factors such as the angle between the precast beam and the movable plate 42, and effectively ensuring the quality and efficiency of the bridge expansion;

[0045] Then, the mounting column 1, the mounting plate 2, and the rectangular tube 3 are moved downward, so that the two clamping plates 43 on the corresponding side are located on the opposite sides of the precast beam. Then, the fourth motor 41 is started to drive the bidirectional screw 48 to rotate. Since the bidirectional screw 48 is threadedly connected to the two movable plates 42, the rotation of the bidirectional screw 48 will cause the two movable plates 42 to move inward, and then the two clamping plates 43 to move inward, so that the precast beam is clamped by the two clamping plates 43. At this time, the two clamping blocks 44 are located at the lower end of the precast beam, thereby supporting the precast beam with high stability.

[0046] If the cross section of the precast beam is T-shaped, two clamping plates 43 are used to clamp the two ends of the transverse portion of the precast beam, and then the electric push rod 46 is activated to drive the corresponding clamping block 44 to move inward and make extrusion contact with the side ends of the vertical portion of the precast beam, thereby clamping the vertical portion of the precast beam, realizing multi-position clamping of precast beams of different shapes, effectively reducing the probability of the precast beam sliding during the lifting process, expanding the scope of use, and effectively ensuring the quality and efficiency of the expanded bridge;

[0047] Then the crane part on the bridge-building machine reels in the lifting rope 11, thereby moving the installation column 1, rectangular tube 3 and other components upward, and then lifting the prefabricated beam. Then, the first motor 5, the third motor 21, the screw rod 7 and the transmission gear 22 and other components are used to make the function box 4 and other components return, so that the lifted prefabricated beam moves to the bottom of the crane part on the bridge-building machine. Then, the crane part on the bridge-building machine is used to move the lifted prefabricated beam above the installation position, and then the lifted prefabricated beam is moved downward for placement, thereby completing the installation of the prefabricated beam, realizing a two-point mechanical clamping and installation operation of the prefabricated beam, and using the crane part on a bridge-building machine for lifting movement, effectively reducing the probability of shaking of the prefabricated beam during the lifting and installation process, effectively ensuring the quality and efficiency of the expanded bridge, and with the same steps as above, multiple prefabricated beams are installed in sequence, thereby completing the renovation and expansion of the bridge.

[0048] Example 2: Figure 1 and Figure 2 As shown, two relatively arranged functional frames 12 with U-shaped cross sections are respectively arranged on the left and right ends of the mounting column 1, and the functional frames 12 are used to provide a mounting carrier for the winding wheel 13, and the two winding wheels 13 are respectively rotatably connected to the two functional frames 12, and the adjusting rope 15 is wound or released through the winding wheel 13, and then the fixed parts of the two fourth driving devices whose output shafts are respectively connected to the two winding wheels 13 are respectively installed on the outer ends of the two functional frames 12, and the winding wheels 13 are driven to rotate through the fourth driving device. The fourth driving device can adopt a second motor 14, and the two adjusting ropes 15 with movable ends symmetrically arranged on the upper end of the rectangular tube 3 are respectively wound on the two winding wheels 13, and the rectangular tube 3 is pulled by the adjusting rope 15.

[0049] When in use, first move the bridge erection machine and move the front leg of the bridge erection machine to the corresponding pier top, then use a vehicle to transport the precast beam to the initial position, and then make the overhead crane on the bridge erection machine lower the lifting rope 11. If the two movable plates 42 and the precast beam are in a front-to-back misalignment state, use the first motor 5, the screw rod 7 and the connecting plate 6 to move the function box 4, the movable plate 42 and other components to the appropriate position. If the precast beam and the rectangular tube 3 are in an angled state, use the third motor 21, the transmission gear 22, the ring gear 24 and the connecting column 23 to rotate the rectangular tube 3 and other components to a suitable angle for adjustment.

[0050] Then, the mounting column 1, mounting plate 2 and rectangular tube 3 and other components are moved downward, so that the two clamping plates 43 on the corresponding side are located on the opposite sides of the precast beam. Then, the fourth motor 41, the bidirectional screw 48, the two moving plates 42 and the two clamping plates 43 are used to clamp the precast beam. Then, the overhead crane on the bridge erection machine reels the lifting rope 11, so that the mounting column 1, rectangular tube 3 and other components are moved upward, thereby lifting the precast beam.

[0051] Then the lifted precast beam is moved to the position just below the overhead crane on the bridge erection machine, and then the overhead crane on the bridge erection machine is used to move the lifted precast beam to the top of the installation position, and then the lifted precast beam is moved downward for placement, thereby completing the installation of the precast beam. If the precast beam tilts when being lowered and placed, first start the second motor 14 located in the low position direction of the precast beam to drive the winding wheel 13 to rotate, and then wind up the corresponding adjustment rope 15, thereby applying an upward pulling force to the corresponding side of the rectangular tube 3, and then rotating the precast beam to a parallel state, thereby achieving adjustment of the precast beam, effectively reducing the probability of damage to the precast beam and the pier top installation position, and effectively ensuring the quality of the expanded bridge.

[0052] Although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
