Description

Technical Field

[0001] This invention relates to the field of bridge pier construction technology, and in particular to a bridge pier construction system. Background Technology

[0002] In bridge design, column piers are a commonly used structural type. Pier construction is one of the key control points in bridge construction. Among the existing technologies, the most common methods for bridge pier construction are hydraulic self-climbing formwork and flip-formwork construction.

[0003] The traditional construction method for highway bridges and municipal viaducts has been to use segmented formwork connected by bolts to form an integral formwork system. Each time the formwork is raised, manual labor is required to loosen the bolts at high altitude, which poses a significant safety hazard and is time-consuming and labor-intensive. Building safety barriers or ladder access around the structure requires substantial cost and a long construction period, resulting in high construction costs. Summary of the Invention

[0004] To address the problems in the prior art, this invention provides a bridge pier construction system that is beneficial for saving construction costs, improving construction efficiency, and reducing the intensity of construction labor.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bridge pier construction system, comprising an automatic formwork, an automatic clamp, a lifting platform body, a middle guide rail of the lifting platform main platform, and a lower guide rail of the lifting platform main platform. The automatic clamp is installed at the bottom of the automatic formwork and is used to fix the position of the automatic formwork on the pier. The middle guide rail of the lifting platform main platform is installed on the side wall of the automatic formwork. The lower guide rail of the lifting platform main platform and the middle guide rail of the lifting platform main platform are slidably connected to form a track for the lifting platform body to climb or descend.

[0006] The automatic clamp includes a door frame, a housing, and a locking device mounted on the housing. The locking device includes a disc spring cylinder, an upper wedge block, and a lower wedge block. A pressure plate is provided between the upper wedge block and the disc spring cylinder, and is connected to the cylinder barrel of the disc spring cylinder through the pressure plate. The door frame is fitted over the cylinder barrel and connected to the housing, and the cylinder barrel can slide within the door frame. A guide plate is provided between the upper and lower wedge blocks, and they are guided and connected through the guide plate. The upper and lower wedge blocks can slide relative to each other along the guide plate. The mating surfaces of the upper and lower wedge blocks are designed with grooves, and needle rollers are installed in the grooves. A pulling system is provided on the housing, and the pulling system includes a power source, gears, and a chain. The interlocking mechanism can pull the lower wedge block. The power source is mounted on the housing, and the gear is mounted on the housing via a shaft. One end of the chain is connected to the end of the power source, and the other end passes around the gear and connects to the top of the lower wedge block. The power source is used to pull the lower wedge block. Damping guide wheel mounting plates are fixed on both sides of the lower wedge block, and damping guide wheels are fixed on the damping guide wheel mounting plates. The damping guide wheel includes a mounting sleeve, a guide wheel, and a roller bracket. The mounting sleeve is fixed to the damping guide wheel mounting plate by a bolt assembly two, and the guide wheel is connected to the roller bracket by a pin assembly two. A first spring is designed between the roller bracket and the mounting sleeve to apply a preload to the guide wheel.

[0007] The optimized technical solution includes a main body and two lifting machines. The two lifting machines are installed at opposite ends of the main body. Each lifting machine is equipped with a main body suspension and safety steel wire rope for lifting the main body. The main body is mounted on the main body and has an arc-shaped structure. A guide structure is also provided on the main body, located inside the arc-shaped structure of the main body. The guide structure is used for connection with the main body, allowing the main body to slide up and down along the upper and lower slide rails with the guide structure as a fulcrum.

[0008] In the optimized technical solution, a C-shaped slide groove extending along the length direction is provided on one side of the guide rail of the main platform of the elevator, and a slider extending along the length direction is provided on one side of the lower guide rail of the main platform of the elevator. The slider is sleeved with the C-shaped slide groove, and the slider can slide along the C-shaped slide groove.

[0009] The optimized technical solution includes an anchor point at the lower end of the lower guide rail of the main platform of the elevator. The anchor point is used to fix the lower end of the lower guide rail of the main platform to the foundation. The anchor point includes a pressure plate and a base plate. The base plate is connected to the foundation by pre-embedded bolts. The lower end of the lower guide rail of the main platform rests on the base plate and is fixed to the base plate by the pressure plate and bolts.

[0010] In the optimized technical solution, the piston rod of the disc spring cylinder is equipped with a spherical bearing, and the spherical bearing is connected to the adjustable ear seat through a pin assembly; the automatic clamp is provided with a fixed ear seat, and the adjustable ear seat of the locking device is connected to the fixed ear seat through a bolt assembly.

[0011] In the optimized technical solution, a clamp-type brake device is installed on the roller bracket. The clamp-type brake device includes a second spring, a connecting rod, and a brake seat. The roller bracket is fixed with an ear seat. The connecting rod's central pin hole is connected to the ear seat on the roller bracket via a pin shaft. One end of the two connecting rods is connected via a screw assembly. The second spring passes through the screw assembly. The other end of the connecting rod is connected to the brake seat via a pin shaft. A brake pad is fixed on the brake seat.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. In the construction of bridge piers and cap beams, the use of automatically lifting elevators to replace ladders and fixed operating platforms has greatly reduced the installation and transportation of modules and improved construction efficiency.

[0014] 2. By setting up a fixed guide structure and retractable interlocking guide rails, the construction problem of bridge piers at different heights was solved, enabling full-height, fully enclosed operation of the bridge piers;

[0015] 3. The main body of the hoist integrates a hoist, which can move up and down along the working rope of the hoist. It also integrates a safety lock, which is equipped with an independent safety rope to prevent falls and improve the safety of the construction hoist.

[0016] 4. The main platform of the construction hoist adopts a modular segmented design. The segmented modules are quickly connected by pins, which facilitates low-level installation and disassembly.

[0017] 5. A row of needle rollers is provided between the upper and lower wedge blocks of the locking device, which can reduce the friction coefficient between the wedge blocks and ensure that the contact between the upper and lower wedge blocks and the pier meets the mechanical self-locking condition.

[0018] 6. The lower wedge block of the locking device is connected to damping guide wheels on both sides to trigger locking. This can generate a certain resistance when the lower wedge block moves downward, thereby creating a speed difference between the upper and lower wedge blocks during an overspeed fall and triggering the locking function.

[0019] 7. The damping guide wheel integrates a clamp-type brake, which can compensate for brake wear through a spring, extending the working life of the damping guide wheel;

[0020] 8. The locking device can be equipped with disc springs to buffer the fall and limit the maximum braking force, so as to avoid structural damage caused by excessive instantaneous impact force.

[0021] 9. The upper wedge block connection structure of the locking device has a certain degree of flexibility to ensure that the contact between the lower wedge block and the pier is not affected by the elastic deformation of the structural components, ensuring balanced load-bearing and avoiding local damage to the surface of the pier.

[0022] 10. After the automatic clamp is locked, the safety clamp housing must be lifted to unlock it, which is safe and reliable;

[0023] 11. The automatic clamp designed in this invention integrates a fall protection function. When the self-climbing device falls unexpectedly, it can be braked and locked to the pier in a short distance, ensuring the overall safety of the equipment.

[0024] 12. The automatic clamp designed in this invention does not affect the normal up and down crawling of the crawler. It will only be triggered when an accidental overspeed fall occurs, and the safety clamp needs to be lifted to unlock it.

[0025] 13. The main body of the elevator of this invention replaces the traditional ladder and fixed operating platform, which greatly reduces the transportation and installation modules and completely solves the problem that the higher the pier, the greater the difficulty when constructing the ladder passage.

[0026] 14. Construction workers can use the main body of the elevator to go to high places for work, avoiding the physical exertion caused by climbing stairs and improving the working environment for construction workers.

[0027] 15. Using this invention, full-height, full-encirclement operation of bridge piers can be achieved, with a wider operation coverage area.

[0028] In summary, the bridge pier construction system of the present invention significantly reduces the construction cost of piers, greatly improves construction efficiency, significantly reduces high-altitude operations, greatly improves safety, and greatly improves the working environment of construction personnel.

The right end of the cylinder 06.01.02.03.05 is spherical, and the contact point between the upper wedge block 06.01.02.09 and the cylinder 06.01.02.03.05 is also spherical, forming a ball joint connection. The top of the upper wedge block 06.01.02.09 is an arc surface, and its contact with the door frame 06.01.02.07 is a line contact, allowing the upper wedge block 06.01.02.09 to adapt to the elastic deformation caused by the load on the box, thereby ensuring effective contact between the lower wedge block 06.01.02.11 and the pier, and preventing damage to the surface of the pier.

[0094] like Figure 10 , Figure 11 As shown, the cylinder barrel 06.01.02.03.05 of disc spring cylinder 06.01.02.03 has two trunnions. These trunnions contact the sliding groove at the door frame 06.01.02.07, providing support and guidance for disc spring cylinder 06.01.02.03. Multiple disc springs 06.01.02.03.04 are installed between the piston rod of disc spring cylinder 06.01.02.03 and the cylinder barrel 06.01.02.03.05, providing elastic cushioning.

[0095] like Figure 12As shown, the upper wedge block 06.01.02.09 and the lower wedge block 06.01.02.11 are connected and guided by the guide plate 06.01.02.12, allowing the upper and lower wedge blocks to slide relative to each other along the guide plate 06.01.02.12. The lower wedge block 06.01.02.11 is designed with a guide groove, and the guide plate 06.01.02.12 is designed as an L-shape and is fixed to both sides of the upper wedge block 06.01.02.09 by fasteners 06.01.02.15, which extend into the guide groove of the lower wedge block 06.01.02.11 to guide and limit the lower wedge block. The mating surfaces of the upper and lower wedge blocks are designed with grooves, and the grooves are equipped with needle rollers 06.01.02.10. The upper and lower wedge blocks contact each other through the needle rollers, which reduces the coefficient of friction between the upper and lower wedge blocks and makes the self-locking performance of the wedge blocks more reliable.

[0096] like Figure 10 , Figure 13 As shown, damping guide wheel mounting plates 06.01.02.14 are fixed on both sides of the lower wedge block 06.01.02.11, and damping guide wheels 06.01.02.06 are fixed on the mounting plates. The damping guide wheel 06.01.02.06 consists of the mounting sleeve 06.01.02.06.01, nut 06.01.02.06.02, first spring 106.01.02.06.03, roller bracket 06.01.02.06.04, guide wheel 06.01.02.06.05, pin assembly 2 06.01.02.06.06, bolt assembly 2 06.01.02.06.07, second spring 06.01.02.06.08, screw assembly 06.01.02.06.09, connecting rod 06.01.02.06.10, brake seat 06.01.02.06.11, and brake pad 06.01.02.06.12.

[0097] Mounting sleeve 06.01.02.06.01 is fixed to damping guide wheel mounting plate 06.01.02.14 via bolt assembly two 06.01.02.06.09. Guide wheel 06.01.02.06.05 is connected to roller bracket 06.01.02.06.04 via pin assembly two 06.01.02.06.06. A first spring 06.01.02.06.03 is designed between roller bracket 06.01.02.06.04 and mounting sleeve 06.01.02.06.01, which can apply a certain load to guide wheel 06.01.02.06.05 to keep it in close contact with the surface of pier column 12.

[0098] like Figure 13 , Figure 14As shown, a clamp-type brake device is installed on the roller bracket 06.01.02.06.04. The clamp-type brake device consists of a second spring 06.01.02.06.08, a screw assembly 06.01.02.06.09, a connecting rod 06.01.02.06.10, a brake seat 06.01.02.06.11, a brake pad 06.01.02.06.12, and a pin 06.01.02.06.13. The roller bracket 06.01.02.06.04 is fixed with an ear seat. The middle pin hole of the connecting rod 06.01.02.06.10 is connected to the ear seat on the roller bracket 06.01.02.06.04 through the pin shaft 06.01.02.06.13. One end of the two connecting rods 06.01.02.06.10 is connected through the screw assembly 06.01.02.06.09. The screw assembly 06.01.02.06.09 is fitted with a second spring 06.01.02.06.08, which can apply an outward elastic force to the two connecting rods. The other end of the connecting rod is connected to the brake seat 06.01.02.06.11 via a pin 06.01.02.06.13. Brake pads 06.01.02.06.12 are fixed on the brake seat. Under the action of the second spring 06.01.02.06.08, the two brake pads 06.01.02.06.12 can clamp the guide wheel, thereby generating a braking torque on the guide wheel 06.01.02.06.05.

[0099] When the self-climbing device experiences an unexpected overspeed fall, the locking device of the safety clamp can be triggered by the damping guide wheel, causing the upper wedge block 06.01.02.09 and the lower wedge block 06.01.02.11 to move closer together. The lower wedge block 06.01.02.11 then presses against the pier and clamps, generating braking force to stop the self-climbing device. The device is then locked in position through self-locking to prevent further slippage and provide effective fall protection.

[0100] By lifting the housing of the safety clamp with external force, the upper wedge block 06.01.02.09 and the lower wedge block 06.01.02.11 can be separated, thus unlocking. When there is no external force to actively lift it, it can effectively self-lock, making it safe and reliable.

[0101] like Figure 16 As shown, the main body 08 of the elevator consists of a safety lock 08.01, a hoist 08.02, an electrical control box 08.03, a guide structure 08.04, a safety door 08.05, and a main body 08.06. The guide structure 08.04 can slide up and down along the upper slide rail 04.03 and the lower slide rail 09.02.

[0102] like Figure 15As shown, the middle guide rail 04 and the lower guide rail 09 of the main platform of the elevator are connected by a C-shaped groove 04.01 and a slider 09.01, allowing them to slide relative to each other to accommodate changes in the height of the automatic clamp 06. When the middle guide rail 04 and the lower guide rail 09 of the main platform slide relative to each other, the set screw 04.02 is loosened. Once the position of the automatic clamp 06 is determined, the set screw 04.02 is tightened, fixing the middle guide rail 04 and the lower guide rail 09 together as the track for the vertical movement of the elevator body 08.

[0103] The anchor point 10 of the lower guide rail of the main platform of the elevator is mainly composed of pre-embedded bolts 10.01, pressure plate 10.02, and base plate 10.03. Its main function is to anchor to the lower guide rail 09 of the main platform of the elevator, so that it is firm and reliable.

[0104] like Figure 16 As shown, the main body 08 of the elevator is designed with an electrical control box 08.03, which integrates manual control and wireless control modules, enabling local operation and remote wireless operation.

[0105] like Figure 16 , Figure 17 As shown, the guide structure 08.04 of the elevator body 08 can slide up and down along the upper slide rail 04.03 and the lower slide rail 09.02 to achieve the purpose of balancing and raising / lowering the elevator body 08. The guide structure 08.04 can be a roller as shown in the figure, or a slider, etc.

[0106] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. It should be noted that any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
