Description

Technical Field

[0001] This invention relates to the field of bridge construction technology, and in particular to a beam lifting device for erecting high bridge piers and beams in mountainous areas. Background Technology

[0002] Beams and slabs are the interconnected beams and slabs in a floor system. Reinforced concrete cast-in-place beam-slab systems are the most widely used and applicable floor system type, and their safety and economy have a significant impact on buildings. In a monolithic cast-in-place floor system, beams and slabs are an interacting whole, closely connected, sharing stress and deformation.

[0003] When constructing roads in mountainous areas or for municipal engineering projects, they are usually built as through-passes. The common method for erecting beams is to build a precast beam yard at the transition roadbed between bridges, and then transport the precast beams directly from the roadbed to the bridge erecting machine on the bridge deck using a beam transport vehicle. This method is limited by the lack of roadbed or short roadbed works in the project section, which cannot meet the requirements for the construction of precast beam yards. In addition, the piers of through-passes in mountainous areas are generally high, making it impossible to build transportation channels that can accommodate beam transport vehicles. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the limitation of processes being restricted by the absence or shortness of roadbeds in engineering project sections, which makes it impossible to meet the construction requirements of precast beam yards, and the fact that elevated bridges in mountainous areas generally have high piers, making it impossible to construct transportation channels that can accommodate beam transport vehicles. Therefore, this invention proposes a beam lifting device for erecting beams and slabs on high bridge piers in mountainous areas.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A beam lifting device for erecting high bridge pier beams in mountainous areas includes multiple beam bodies and four first support frames disposed between multiple bridge pier bases. The top of each bridge pier base is provided with a foot pier surface for placing the beam body. The four first support frames are arranged symmetrically in pairs. The top of the two first support frames located on the same side is provided with the same second support frame. The top of the second support frame is provided with a lifting component for lifting the beam body.

[0007] It also includes two symmetrically arranged second fixing plates, and a fixing base plate is fixedly connected to the side of the two second fixing plates that are close to each other. The top of the fixing base plate is provided with a support component for temporarily supporting the beam plate body.

[0008] It also includes multiple first fixed rails set above the beam body and a second fixed rail set above the foot pier surface. The top of the second fixed rail and the first fixed rail are provided with a second mounting crossbar. The top of the second mounting crossbar located above the second fixed rail is fixedly connected to two symmetrically arranged hydraulic rods. The top of the two hydraulic rods and the top of the second mounting crossbar located above the first fixed rail are all provided with the same first mounting crossbar. The top of the first mounting crossbar is fixedly connected to two symmetrically arranged side top plates. One side of the side top plate is fixedly connected to a reinforcing rod. The top of the multiple side top plates is fixedly connected to the same third support frame. The top of the third support frame is provided with two second winches for moving the beam body.

[0009] The bottom of the second mounting bar is provided with a drive component for driving the first mounting bar to move;

[0010] The bottom of the second fixed track is slidably connected to two symmetrically arranged sliding blocks, and clamping components for clamping the foot block surface are provided on both sides of the sliding blocks.

[0011] In one possible design, the lifting assembly includes a first mounting bracket slidably connected to the top of a second support frame. A first winch is disposed inside the first mounting bracket. A first fixing plate is fixedly connected to both sides of the top of the second support frame. A first servo motor is fixedly connected to one side of the first fixing plate. The output shaft of the first servo motor rotates through the first fixing plate and is fixedly connected to a first lead screw. The first lead screw is threaded through the first mounting bracket.

[0012] In one possible design, the support assembly includes two symmetrically arranged support horizontal plates slidably connected to the top of a fixed base plate. A first sliding strip is slidably connected to the top of the fixed base plate, and one side of the first sliding strip is fixedly connected to one end of the two support horizontal plates. A support vertical plate is fixedly connected to one side of the bottom of each support horizontal plate, and a side plate is fixedly connected to the top of each support horizontal plate. A first electric push rod is fixedly connected to one side of a second fixed plate, and the piston rod of the first electric push rod is fixedly connected to one side of the first sliding strip.

[0013] In one possible design, the drive assembly includes four first rectangular plates fixedly connected to the bottom of the second mounting bar and arranged symmetrically in pairs. The same first rotating shaft is rotatably connected between two first rectangular plates on the same side. A movable wheel is fixedly sleeved on the outer wall of the first rotating shaft. A second servo motor is fixedly connected to one side of one of the first rectangular plates. The output shaft of the second servo motor rotatably passes through the first rectangular plate and is fixedly connected to one end of one of the first rotating shafts.

[0014] In one possible design, the clamping assembly includes two second rectangular plates that are fixedly connected to both sides of the sliding block and are symmetrically arranged. The two second rectangular plates are rotatably connected to the same third rotating shaft. A cylinder is fixedly sleeved on the outer wall of the third rotating shaft. A clamping plate is fixedly sleeved on the outer wall of the cylinder. Slotted holes are opened on both sides of the second fixed track. The clamping plate passes through the slotted holes. Multiple friction strips are provided on one side of the clamping plate.

[0015] In one possible design, the top of the sliding block has a groove, and the inner walls of both sides of the groove are slidably connected to the same threaded plate. The bottom of the sliding block is fixedly connected to a third servo motor. The output shaft of the third servo motor rotatably passes through the sliding block and is fixedly connected to a second lead screw. The second lead screw threadedly passes through the threaded plate. Both ends of the threaded plate are fixedly connected to second sliding strips. The bottom of the second sliding strips is fixedly connected to two symmetrically arranged racks. A rectangular block is fixedly connected to one side of the sliding block. Both sides of the rectangular block are rotatably connected to worm gears. The outer wall of the worm gear is fixedly fitted with a spur gear that meshes with the racks. Both ends of the third rotating shaft rotatably pass through the second rectangular plate and are fixedly connected to a second rotating shaft. The outer wall of the second rotating shaft is fixedly fitted with a worm wheel that meshes with the worm gear.

[0016] In one possible design, two positioning grooves are provided on one side of the supporting horizontal plate, and two positioning blocks are fixedly connected to one side of the supporting horizontal plate. The positioning blocks and positioning grooves are staggered and interlocked. The positioning blocks and positioning grooves on one side of the two supporting horizontal plates on both sides correspond to each other. A sliding plate is slidably connected to one side of the side plate, and a rubber pad is fixedly connected to the top of the supporting horizontal plate. The rubber pad is used in conjunction with the sliding plate.

[0017] In one possible design, a first limiting block is fixedly connected to both ends of the first fixed track, and a second limiting block is fixedly connected to both ends of the second fixed track. The two second limiting blocks are rotatably connected to the same bidirectional lead screw. A fourth servo motor is fixedly connected to one side of one of the second limiting blocks. The output shaft of the fourth servo motor rotatably passes through the second limiting block and is fixedly connected to the bidirectional lead screw. The bidirectional lead screw is threaded through two sliding blocks.

[0018] In one possible design, the top of the positioning block has a slot, the top of the positioning slot has a through hole, and the bottom of the sliding plate is fixedly connected to two symmetrically arranged locking rods, which pass through the through hole and engage with the slot.

[0019] In this application, during use, after the beam body is moved to a suitable location by a transport vehicle, two first electric push rods can be activated. The piston rod of the first electric push rod drives the first sliding bar to move laterally. The first sliding bar drives the two supporting horizontal plates to move laterally. The supporting horizontal plates drive the supporting vertical plates to move laterally. The supporting horizontal plates drive the side plates to move laterally. At this time, the two supporting vertical plates abut against each other, and then the multiple positioning blocks located on both sides are inserted into the corresponding positioning slots, thereby improving the stability of the device connection.

[0020] At this point, the beam body is lowered, and its weight presses the sliding plate vertically downwards. The clamping rod then enters the positioning groove through the through hole and engages with the corresponding clamping groove, further enhancing the stability of the device connection and ensuring that the beam body will not come loose. At this point, the two transport vehicles can leave in advance, which not only improves work efficiency but also allows the vehicles to quickly move away from the construction site, improving the safety of the device.

[0021] The two first winches are used to tighten the two ends of the beam body and wind up the steel cable. At this time, the beam body can be lifted upward. The first servo motor is started. The output shaft of the first servo motor drives the first lead screw to rotate. The first lead screw drives the first mounting frame to move laterally. The first mounting frame drives the first winch to move laterally, thereby moving the beam body to the two pier bases, which facilitates the installation of the beam body.

[0022] After the beam body located between the two first mounting frames is installed, if the terrain in front is complex and it is not convenient to install the first support frame, multiple first fixed rails and second fixed rails can be installed and erected on the beam body and the pier surface respectively. Since the second installation crossbar on the second fixed rail is low, a hydraulic rod is set above it to ensure that the horizontal plane of multiple second installation crossbars is consistent. At this time, multiple side top plates can be used to install the same third support frame. Two second winches are installed on the third support frame. The second winches can be used to move the excess beam body to the installation location in front and install it on the top of the pier surface.

[0023] Furthermore, the second servo motor can be activated, and the output shaft of the second servo motor drives the first rotating shaft to rotate. The first rotating shaft drives the moving wheel to rotate, which in turn drives the second mounting crossbar to move laterally and adjusts the position of the third support frame. In this way, multiple beams can be installed on the foot piers at different positions. The length of the third support frame can be increased. By repeating this process, the installation of beams in complex areas can be completed without adjusting the position of the first support frame.

[0024] When installing the second fixed track for bridge pier bases of different sizes, the fourth servo motor can be started. The output shaft of the fourth servo motor drives the bidirectional lead screw to rotate, and the bidirectional lead screw drives the two sliding blocks to move laterally. At this time, the two sliding blocks drive the two clamping plates to move laterally. After the two clamping plates move to the appropriate position, they can be adapted to the size of the pier surface, thereby improving the applicability of the device.

[0025] Then, the third servo motor is started. The output shaft of the third servo motor drives the second lead screw to rotate. The second lead screw drives the threaded plate to move vertically downward. The threaded plate drives the two second sliding bars to move vertically downward. The second sliding bars drive the rack to move vertically downward. The rack drives the spur gear to rotate. The spur gear drives the worm gear to rotate. The worm gear drives the worm wheel to rotate. The worm wheel drives the second rotating shaft to rotate. The second rotating shaft drives the third rotating shaft to rotate. The third rotating shaft drives the cylinder to rotate. The second rotating shaft drives the clamping plate to rotate. The clamping plate clamps the two sides of the foot block surface to ensure the stability of the second fixed track. At the same time, the friction strip can be used to increase the friction force to ensure stability and make it easy to use.

[0026] In this invention, the beam lifting device for erecting high bridge piers and beams in mountainous areas can achieve the effect of quickly lifting the beam body by setting up lifting components.

[0027] In this invention, the beam lifting device for erecting high bridge piers and beams in mountainous areas can temporarily support the beam body by setting up support components, thereby improving the stability of the device connection and ensuring that the beam body will not loosen.

[0028] In this invention, the beam lifting device for erecting high bridge pier beams in mountainous areas can adjust the lateral position of the beam body by setting the drive components, which facilitates the laying of the beam body.

[0029] In this invention, the lifting device for erecting high bridge piers and beams in mountainous areas can achieve the effect of quickly clamping the pier surface by setting the clamping components, and can also adapt to the size of the pier surface, thereby expanding the applicability of the device.

[0030] In this invention, the beam body can be supported by a support component, and the two transport vehicles can leave in advance, which not only improves work efficiency, but also allows the vehicles to quickly move away from the construction site, improving the safety of the device. After the beam body is moved to the two pier bases, it can be moved forward again by a third support frame. The lateral position of the beam body can be adjusted by the drive component to complete the installation. Construction can be carried out in harsh terrain. The two clamping plates can also be used to clamp the pier surface to adapt to the size of the pier surface, thereby expanding the applicability of the device. Attached Figure Description

The output shaft of the first servo motor 11 rotates through the first fixing plate 10 and is fixedly connected to the first lead screw 8. The first lead screw 8 is threaded through the first mounting frame 6. The two ends of the beam body 5 are tightened by the two first winches 9 and the steel cable is wound up. At this time, the beam body 5 can be lifted upward. The first servo motor 11 is started. The output shaft of the first servo motor 11 drives the first lead screw 8 to rotate. The first lead screw 8 drives the first mounting frame 6 to move laterally. The first mounting frame 6 drives the first winch 9 to move laterally, thereby moving the beam body 5 to the two pier bases 1, which facilitates the installation of the beam body 5.

[0049] It also includes two symmetrically arranged second fixing plates 15. A fixing base plate 17 is fixedly connected to one side of each second fixing plate 15 that is close to each other. A support assembly for temporarily supporting the beam body 5 is provided on the top of the fixing base plate 17. The support assembly includes two symmetrically arranged support horizontal plates 13 slidably connected to the top of the fixing base plate 17.

The piston rod of the first electric push rod 16 drives the first sliding bar 14 to move laterally. The first sliding bar 14 drives the two supporting horizontal plates 13 to move laterally. The supporting horizontal plates 13 drive the supporting vertical plates 18 to move laterally. The supporting horizontal plates 13 drive the side plates 7 to move laterally. At this time, the two supporting vertical plates 18 abut against each other, and then the multiple positioning blocks 19 located on both sides are inserted into the corresponding positioning slots 20 respectively, improving the stability of the device connection.

[0050] It also includes multiple first fixed rails 27 set above the beam body 5 and a second fixed rail 39 set above the pier surface 3. The top of both the second fixed rail 39 and the first fixed rail 27 is provided with a second mounting crossbar 31.

Two second winches 26 are provided for moving the beam body 5. After the beam body 5 located between the two first mounting frames 6 is installed, if the terrain in front is complex and it is not convenient to install the first support frame 2, multiple first fixed rails 27 and second fixed rails 39 can be installed and erected on the beam body 5 and the foot pier surface 3 respectively. Since the second mounting crossbar 31 on the second fixed rail 39 is low, a hydraulic rod 38 is set above it to ensure that the horizontal planes of multiple second mounting crossbars 31 are consistent. At this time, multiple side top plates 30 can be used to install the same third support frame 25. Two second winches 26 are installed on the third support frame 25.

The output shaft of the third servo motor 53 drives the second lead screw 54 to rotate. The second lead screw 54 drives the threaded plate 55 to move vertically downward. The threaded plate 55 drives the two second sliding bars 47 to move vertically downward. The second sliding bars 47 drive the rack 51 to move vertically downward. The rack 51 drives the spur gear 50 to rotate. The spur gear 50 drives the worm 52 to rotate. The worm 52 drives the worm wheel 44 to rotate. The worm wheel 44 drives the second rotating shaft 49 to rotate. The second rotating shaft 49 drives the third rotating shaft 57 to rotate. The third rotating shaft 57 drives the cylinder 48 to rotate. The second rotating shaft 49 drives the clamping plate 37 to rotate. The clamping plate 37 clamps the two sides of the foot block surface 3 to ensure the stability of the second fixed track 39. At the same time, the friction bar 42 can be used to increase the friction force to ensure stability and make it easy to use.

[0054] Two positioning grooves 20 are provided on one side of the supporting horizontal plate 13. Two positioning blocks 19 are fixedly connected to one side of the supporting horizontal plate 13. The positioning blocks 19 and positioning grooves 20 are staggered and engaged. The positioning blocks 19 and positioning grooves 20 on one side of the two supporting horizontal plates 13 on both sides correspond to each other. A sliding plate 12 is slidably connected to one side of the side plate 7. A rubber pad 22 is fixedly connected to the top of the supporting horizontal plate 13. The rubber pad 22 is used in conjunction with the sliding plate 12.

[0055] First limiting blocks 29 are fixedly connected to both ends of the first fixed track 27, and second limiting blocks 40 are fixedly connected to both ends of the second fixed track 39. The same bidirectional lead screw 45 is rotatably connected between the two second limiting blocks 40. A fourth servo motor 41 is fixedly connected to one side of one of the second limiting blocks 40. The output shaft of the fourth servo motor 41 rotatably passes through the second limiting block 40 and is fixedly connected to the bidirectional lead screw 45. The bidirectional lead screw 45 is threaded through two sliding blocks 46.

[0056] The top of the positioning block 19 has a slot 24, and the top of the positioning groove 20 has a through hole 23. The bottom of the sliding plate 12 is fixedly connected to two symmetrically arranged locking rods 21. The locking rods 21 pass through the through hole 23 and engage with the slot 24. When the beam plate body 5 is lowered, the weight of the beam plate body 5 presses the sliding plate 12 vertically downward. At this time, the locking rods 21 enter the interior of the positioning groove 20 through the through hole 23 and engage with the corresponding slot 24, which further improves the stability of the device connection and ensures that the beam plate body 5 will not loosen. At this time, the two transport vehicles can leave in advance, which not only improves work efficiency, but also allows the vehicles to quickly leave the construction site and improves the safety of the device.

[0057] However, as is well known to those skilled in the art, the working principles and wiring methods of the first electric push rod 16, the first servo motor 11, the second servo motor 33, the fourth servo motor 41, the third servo motor 53 and the hydraulic rod 38 are commonplace and belong to conventional means or common knowledge.
