Description

Technical Field

[0001] This invention relates to the field of bridge construction technology, specifically to a mobile hanging basket for bridge engineering. Background Technology

[0002] Bridge engineering refers to the process of surveying, designing, constructing, maintaining, and inspecting bridges. It is a branch of civil engineering. Mobile hanging baskets are generally used in bridge construction. They are the main equipment in cantilever construction and can be classified into four types according to their structure: truss type, cable-stayed type, steel type, and hybrid type. The mobile hanging basket is mainly composed of a main truss, suspension system, anchoring system, traveling system, and formwork. The design of the mobile hanging basket should meet the principles of light weight, simple structure, sturdiness and stability, easy forward movement and assembly / disassembly, and strong reusability.

[0003] The existing mobile formwork used in bridge engineering has the following drawbacks during construction: 1. Traditional diamond-shaped formwork generally requires electric drive for movement during construction. However, the traditional power generation equipment is heavy and inconvenient to carry. Furthermore, the preheating process for starting the power generation equipment is cumbersome, requiring continuous operation to ensure that the formwork can be adjusted at any time. This operation method may cause the power generation equipment to overheat and be damaged due to prolonged continuous operation, thus affecting the overall construction progress; 2. Due to the large overall inertia of traditional diamond-shaped formwork during movement, a low movement speed must be maintained when driving and traction the formwork to prevent the formwork from being unable to be accurately positioned during traction. This method of adjusting the formwork is time-consuming, resulting in slow overall construction efficiency. Summary of the Invention

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1A mobile hanging basket for bridge engineering includes a pier 1, a beam 2, a guide rail mechanism 3, a moving mechanism 4, a lifting mechanism 5, a traction mechanism 6, and a bridge formwork 7. The beam 2 is fixedly mounted on the upper surface of the pier 1. The guide rail mechanism 3 is symmetrically fixedly mounted on the left and right sides of the front end of the upper surface of the beam 2. The moving mechanism 4 is slidably mounted on the upper side of the guide rail mechanism 3. The lifting mechanism 5, which is slidably engaged with the beam 2, is symmetrically fixedly mounted on the left and right sides of the moving mechanism 4. The traction mechanism 6 is fixedly mounted on the front and rear ends of the lifting mechanism 5 and the front end of the guide rail mechanism 3. The bridge formwork 7, which is raised and lowered in cooperation with the traction mechanism 6, is mounted on the lower side of the lifting mechanism 5. The bridge formwork 7 consists of symmetrical side formworks on the left and right sides, a bottom formwork on the lower side, and a guardrail at the front end of the bottom formwork. Four supports that cooperate with the lifting mechanism 5 are symmetrically fixedly mounted on the left and right sides of the upper surface of the bridge formwork 7.

[0031] Please see Figure 3 and Figure 5 The guide rail mechanism 3 includes a pad 31, a guide rail 32, a rack 33, and a rail anchor 34. Pads 31 are symmetrically fixed on the left and right sides of the front end of the upper surface of the beam 2. The guide rail 32 is fixed on the upper surface of the pad 31. Four racks 33 are symmetrically fixed on the left and right sides of the guide rail 32 through plates. The rail anchor 34 is fixed on the front end of the upper surface of the guide rail 32. The traction mechanism 6, which cooperates with the moving mechanism 4 for transmission, is fixed on the upper surface of the rail anchor 34.

[0032] Please see Figure 1 and Figure 3 The moving mechanism 4 includes a main truss 41, a horizontal truss 42, an upper crossbeam 43, and a moving component 44. Two main trusses 41 that cooperate with the guide rail 32 are symmetrically arranged on the left and right sides of the front end of the beam 2. The main trusses 41 are fixedly connected to each other through the horizontal truss 42 in the middle section and the upper crossbeam 43 at the front end. The front and rear ends of the lower surface of the main truss 41 are provided with moving components 44 that slide with the guide rail 32.

[0033] Please see Figure 3 and Figure 4 The movable component 44 includes a movable base 441, a locking part 442, track wheels 443, an adjusting screw 444, and an adjusting plate 445. The movable base 441 is fixedly installed at both the front and rear ends of the lower surface of the main truss 41. The locking parts 442 are symmetrically arranged on the left and right sides of the movable base 441. Four track wheels 443 are symmetrically rotatably arranged on the left and right sides inside the movable base 441. The adjusting screw 444 is threadedly engaged at the outer ends of the two track wheels 443 at the rear end of the movable base 441. The adjusting plate 445 is fixedly installed at the outer end of the adjusting screw 444.

[0034] Please see Figure 4 The locking part 442 includes a locking plate 4421, a threaded sleeve 4422, a sliding sleeve 4423, a driving sleeve 4424, a driven gear 4425, a driven slide rod 4426, a driven screw 4427, and a locking disc 4428. The left and right sides of the movable base 441 are symmetrically fixed with locking plates 4421 via plates. A threaded sleeve 4422 is fixedly installed on the inner surface of the locking plate 4421, and a sliding sleeve 4423 is fixedly installed on the outer surface of the locking plate 4421. The sliding sleeve 4423 contains... A drive sleeve 4424 is elastically slidably provided. A driven gear 4425 that engages with a rack 33 is fixedly provided at the outer end of the drive sleeve 4424. A rectangular columnar driven slide rod 4426 is slidably provided inside the drive sleeve 4424. A driven screw 4427 that engages with a threaded sleeve 4422 is fixedly provided at the inner end of the driven slide rod 4426. A locking disc 4428 is fixedly provided at the inner end of the driven screw 4427. A friction damping plate is fixedly provided on the inner surface of the locking disc 4428.

[0035] When the main truss 41 moves forward along the guide rail 32 to a specific position under the traction of the traction mechanism 6, the driven gear 4425 and the rack 33 rotate. The drive sleeve 4424 then drives the driven slide rod 4426 to rotate, causing the driven screw 4427 and the threaded sleeve 4422 to gradually engage the friction damping plate on the surface of the locking disc 4428 and press it against the adjusting plate 445. The friction damping plate on the surface of the locking disc 4428 gradually decelerates the track wheel 443 by gradually contacting it with friction until it fully presses against the adjusting plate 445. The main truss 41 is gradually decelerated and accurately positioned until it is locked in place. At the same time, the initial positions of the driven screw 4427 and the locking disc 4428 can be adjusted to accurately control the locking position of the main truss 41, ensuring that the main truss 41 and the bridge formwork 7 that moves synchronously with the main truss 41 can be accurately positioned. This operation method solves the problem that the mobile formwork is difficult to position accurately due to its large overall inertia and can only move at a low speed. It reduces the time spent on the movement and positioning of the formwork and thus improves the overall efficiency of bridge construction.

[0036] When the driven gear 4425, in cooperation with the rack 33, drives the locking disc 4428 to lock and position the track wheel 443 and the main truss 41, if it is necessary to adjust the position of the main truss 41 again, the adjusting screw 444 at the outer end of the track wheel 443 can be rotated to move the adjusting plate 445 inward until it disengages from the friction damping plate on the surface of the locking disc 4428. By controlling the distance between the adjusting plate 445 and the locking disc 4428, the position of the main truss 41 can be accurately controlled for repositioning and locking. This adjustment method not only ensures the flexibility of the main truss 41 movement adjustment, but also ensures the accuracy of the main truss 41 movement positioning, and makes the construction operation more flexible and convenient.

[0037] When the driven gear 4425 moves to the front end of the rack 33, if it is necessary to adjust or reset the position of the locking disc 4428, the driven gear 4425 can be pulled outward to disengage it from the rack 33, thereby avoiding the rack 33's obstruction of the rotation adjustment of the driven gear 4425. At this time, the position of the locking disc 4428 can be adjusted by rotating the driven gear 4425. This operation method can further improve the flexibility of construction operations and the movement and positioning of the main truss 41.

[0038] Please see Figure 1 and Figure 3 The lifting mechanism 5 includes a U-shaped connecting plate 51 and a pulley block 52; the left and right sides of the front end of the beam 2 are symmetrically and slidably provided with U-shaped connecting plates 51 that are fixedly connected to the main truss 41 through connecting rods; the front and rear ends of the upper surface of the U-shaped connecting plate 51 are fixedly provided with traction mechanisms 6; the outer side of the rear end and the front side of the U-shaped connecting plate 51 are provided with pulley blocks 52 that cooperate with the traction mechanisms 6 for transmission.

[0039] Please see Figure 1 and Figure 3 The pulley block 52 includes a fixed pulley 521, a movable pulley 522, and a connecting part 523. Fixed pulleys 521 are symmetrically fixed at both ends of the lower surface of the flat truss 42 and the lower ends of the upper crossbeam 43 by connecting rods. Movable pulleys 522 are provided on the lower side of the fixed pulleys 521 by cables. A connecting part 523 is fixedly provided on the lower surface of the movable pulley 522 and is connected to the support on the upper surface of the bridge template 7.

[0040] Please see Figure 1 and Figure 2The connecting part 523 includes a connecting frame 5231, an elastic sleeve 5232, a positioning pin 5233, a first pull rod 5234, a limiting groove 5235, a threaded seat 5236, and a threaded pin 5237. The connecting frame 5231 is fixedly provided on the lower surface of the movable pulley 522. An elastic sleeve 5232 is fixedly provided on one side of the connecting frame 5231. A positioning pin 5233 is elastically and slidably provided inside the elastic sleeve 5232 and is inserted into the support on the upper surface of the bridge template 7. A first pull rod 5234 is fixedly provided at the inner end of the positioning pin 5233 and is slidably engaged with the outer end of the elastic sleeve 5232. A limiting groove 5235 is provided at the outer end of the positioning pin 5233. A threaded seat 5236 is fixedly provided on the other side of the connecting frame 5231. A threaded pin 5237 is slidably inserted into the limiting groove 5235 inside the threaded seat 5236.

[0041] When the height of the bridge formwork 7 needs to be adjusted, the traction mechanism 6 can be manually driven to move the four corners of the upper surface of the bridge formwork 7 in a synchronous manner with the fixed pulley 521 and the movable pulley 522. This operation method is relatively labor-saving and can be operated and adjusted at any time by manual driving. It avoids the problem of long start-up and preheating time of traditional power generation equipment affecting the construction progress. At the same time, the traction mechanism 6 can achieve automatic locking, thereby ensuring the stability and safety of the bridge formwork 7 during the construction process.

[0042] When the U-shaped connecting plate 51 moves synchronously with the main truss 41, the traction mechanisms 6 at both ends of the U-shaped connecting plate 51 also move synchronously, so that the traction mechanism 6 can adjust the bridge formwork 7 at any time. This avoids the need to repeatedly disassemble and assemble the traction mechanism 6 during the movement and positioning of the main truss 41, simplifies the construction process, and further improves the overall construction efficiency.

[0043] When installing and positioning the movable pulley 522 with the support on the upper surface of the bridge formwork 7, the support can be aligned with the connecting frame 5231 and inserted. Under the action of the spring in the elastic sleeve 5232, the positioning pin 5233 can be quickly inserted and positioned into the support, thereby achieving rapid installation. Finally, by turning the threaded pin 5237, it is inserted into the limiting through groove 5235, thereby locking the positioning pin 5233, ensuring the stability of the bridge formwork 7 connection during construction. At the same time, this installation method is convenient for disassembly, further improving the efficiency of bridge formwork 7 assembly and disassembly.

[0044] Please see Figure 3 , Figure 5 and Figure 6The traction mechanism 6 includes a traction frame 61, a winding assembly 62, a gear assembly 63, a positioning assembly 64, and a drive assembly 65.

[0046] Please see Figure 6 and Figure 7 The gear assembly 63 includes a first connecting shaft 631, a take-up gear 632, a first pinion 633, a second insert 634, a second connecting shaft 635, a connecting gear 636, and a second pinion 637. The first connecting shaft 631 is movably disposed within one side surface of the traction frame 61. The inner end of the first connecting shaft 631 is rotatably disposed with a take-up gear 632 that elastically slides with the first insert 623. The outer end of the first connecting shaft 631 is fixedly disposed with a first pinion 633. A rectangular columnar second insert 634 is fixedly disposed on the outer surface of the first pinion 633. Symmetrically arranged on both sides of the first connecting shaft 631 are second connecting shafts 635 that rotatably engage with the surface of the traction frame 61. The outer end of the second connecting shaft 635 is fixedly disposed with a connecting gear 636 that engages with the first pinion 633 for transmission. The inner end of the second connecting shaft 635 is fixedly disposed with a second pinion 637 that engages with the take-up gear 632 for transmission.

[0047] Please see Figure 6 and Figure 7The positioning component 64 includes a positioning sleeve 641, a retainer 642, a retaining plate 643, a second pull rod 644, a positioning disk 645, and a positioning through hole 646. The positioning sleeve 641 is fixedly installed on the outer surface of the traction frame 61 on the same side as the first connecting shaft 631 through a connecting plate. The retainer 642 is fixedly installed in the middle section of the upper surface of the positioning sleeve 641. The retaining plate 643 is elastically slidably installed in the retainer 642. The second pull rod 644, which is slidably connected to the upper end of the retainer 642, is fixedly installed on the upper surface of the retaining plate 643. The positioning disk 645 is fixedly installed at the outer end of the positioning sleeve 641. The positioning disk 645 has positioning through holes 646 evenly opened on its surface.

[0048] Please see Figure 6 and Figure 7 The drive assembly 65 includes a snap-fit ​​connector 651, a rotating handle 652, a positioning screw 653, and a drive rod 654. The snap-fit ​​connector 651, which slides inside the positioning sleeve 641, is slidably engaged with the second insert post 634. The rotating handle 652 is fixedly mounted on the outer end of the snap-fit ​​connector 651 via a connecting rod. The positioning screw 653, which is threadedly engaged with the positioning through hole 646, is fixedly mounted on the outer end of the positioning screw 653. The drive rod 654 is fixedly mounted on the outer end of the positioning screw 653.

[0049] When the main truss 41 needs to be moved and adjusted by traction mechanism 6, or when the bridge formwork 7 needs to be raised and lowered by pulley block 52, the drive rod 654 is rotated to drive the handle 652 and the locking connector 651 to rotate. The locking connector 651 drives the second insert 634 to rotate, causing the pinion 633 to engage with the connecting gear 636 for transmission. The pinion 637 then rotates and drives the winding gear 632 to rotate through meshing transmission. The winding gear 632 drives the winding reel 622 to wind up the rope fixedly connected to the main truss 41 or connected to the moving pulley 522 by driving the first insert 623 to rotate, thereby driving the adjustment of the main truss 41 or the bridge formwork 7. The number of teeth on pinion 637 is much smaller than that on connecting gear 636 and winding gear 632. Therefore, the torque input by manual means can be amplified once by the transmission of pinion 633 in conjunction with connecting gear 636. Then, the torque input by manual means can be amplified again by the transmission of pinion 637 in conjunction with winding gear 632. Thus, the torque amplification through the two interactions between gear components 63 enables manual driving of the main truss 41 or bridge formwork 7 for adjustment. This allows manual driving to replace electric driving, avoiding the inconvenience of carrying traditional power generation equipment. It also solves the problem of construction progress being affected by overheating damage to power generation equipment, ensuring the stability and efficiency of the bridge construction process.

[0050] When the traction mechanism 6, in conjunction with the pulley block 52, adjusts the bridge formwork 7 to the designated position, the positioning screw 653 can be turned to insert it into the positioning through hole 646, thereby locking the rotation of the winding reel 622 through the locking handle 652. This prevents the bridge formwork 7 from becoming loose during construction and ensures the stability and safety of the bridge formwork 7.

[0051] When the guide rail 32 needs to be adjusted for the next stage of bridge construction, the track anchor 34 used to reinforce the guide rail 32 also needs to be adjusted forward to a suitable position. The traction mechanism 6 on the upper surface of the track anchor 34 can be adjusted synchronously, thereby avoiding repeated disassembly and assembly of the traction mechanism 6 and simplifying the construction process. At the same time, in order to facilitate the winding and unwinding of the rope in the traction mechanism 6, the clamp plate 643 can be pulled into the clamp seat 642 through the second pull rod 644 and the clamp connector 651 can be pulled out from the positioning sleeve 641. At this time, under the action of the spring on the surface of the first insert 623, the winding gear 632 disengages from the first insert 623, allowing the winding reel 622 to rotate freely to wind and unwind the rope, thereby making the construction operation more flexible and convenient.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
