Description

Technical Field

[0001] This invention relates to the field of municipal bridge and highway construction technology, and in particular to a multi-functional anti-collision wall construction trolley. Background Technology

[0002] As an important component of bridge and highway ancillary structures, crash barriers play a crucial role in buffering the kinetic energy of vehicle impacts, preventing accident vehicles from running off the bridge and falling, and avoiding secondary fatal injuries to drivers. At the same time, because crash barriers are located within the visible area of ​​the bridge, they also beautify and decorate the appearance of the road and guide the driver's line of sight.

[0003] Among various types of guardrails, cast-in-place concrete crash barriers have become the primary form of crash barrier used on highway bridges due to their advantages such as good impact resistance, continuous alignment, and high durability. In the construction process of cast-in-place crash barriers, formwork installation and dismantling, and concrete pouring are crucial factors determining the construction quality. Traditional methods typically involve using forklifts to transport and install the inner formwork, and using cranes in conjunction with workers to install the outer formwork. This approach often suffers from high machine usage and low formwork installation efficiency. In recent years, formwork trolleys have emerged, which integrate formwork lifting and installation equipment by adding a hoisting device to a movable vehicle. They also provide workers with a construction basket, effectively protecting the safety of construction personnel on the outer side of the bridge deck.

[0004] The existing method uses a formwork trolley for construction. After the initial formwork is erected, manual adjustments are required to meet the formwork installation requirements. When construction workers adjust the formwork position on the outside of the bridge deck, the working platform is relatively narrow and they are working at height. As a result, problems such as large formwork joints and non-standard installation are still likely to occur after the formwork is adjusted. In addition, after the formwork trolley completes the formwork erection and dismantling operations, it basically does not participate in other construction processes of the crash barrier.

[0034] This invention provides a multi-functional anti-collision wall construction trolley, such as... Figures 1-3As shown, it includes: an electrical system, a trolley body 1 electrically connected to the electrical system, a hoisting system 3, and a formwork construction platform 6. The formwork construction platform is used for formwork installation, dismantling, and concrete pouring. The trolley body 1 is driven by a drive device 7. The hoisting system 3 is mounted on the trolley body 1, and the formwork construction platform 6 is mounted on the hoisting system 3. An imaging device 5 is mounted on the hoisting system 3. The drive device 7 is a motor. The multi-functional anti-collision wall construction trolley provided by this invention can realize full-process monitoring of formwork installation, dismantling, and concrete pouring. The trolley body 1 and the hoisting system 3 have sufficient working space. The concrete pouring truck can move synchronously with the trolley body 1. Combined with the formwork construction platform 6 and the imaging device 5, the pouring process can be intelligently analyzed, and the pouring time can be reasonably controlled, reducing the manpower input on the construction site. The load capacity of the trolley can be controlled by dismantling the construction basket 63. The overall structure of the trolley has reasonable stress distribution, making it convenient to hoist. The trolley's self-propelled movement and braking are stable. The operating mechanism 64, in conjunction with the trolley, can be used independently for the construction of bridges and highway median strips. The trolley has a wide range of applications. The whole machine is connected to the electrical system. The trolley's movement, formwork hoisting, and concrete pouring can be controlled wirelessly at the terminal. Each mechanism can also be controlled individually using a remote control handle, resulting in a high degree of automation.

[0035] Preferably, the trolley body 1 includes a support base 11, a column 12, and rollers 13. The rollers 13 are mounted on the support base 11. One end of the column 12 is connected to the support base 11, and the other end of the column 12 is connected to the hoisting system 3. The lower part of the trolley body 1 is the support base 11, and the rollers 13 are installed below the support base 11. The end of the column 12 is welded to the middle of the top surface of the support base 11 to enhance its sturdiness. The rollers 13 are four rubber wheels, including driven wheels 131 and drive wheels 132. The drive wheels 132 are located at the rear of the trolley in the direction of travel, fixed to the lower part of the support base 11 and driven by a motor. The driven wheels 131 are located at the front. The two wheels are connected by a connecting device 133 so that the two wheels turn at the same angle when turning. The support base 11 is equipped with a motor that drives the trolley body 1 and the hoisting system 3.

[0036] Furthermore, the number of columns 12 is at least two, and a connecting frame 2 is provided between two adjacent columns 12. The columns 12 can be made of welded steel sections and steel plates, and the connecting frame 2 is a truss made of steel sections. The connecting frame 2 is provided to enhance the overall stability.

[0037] Furthermore, the hoisting system 3 includes a cantilever 31, a traveling beam 32, and a lifting trolley 34. Connecting rods 9 are provided at both ends of the cantilever 31, positioned above both ends to connect the cantilever 31 as a whole. The cantilever 31 is connected to the column 12 at approximately one-third of its length from the end. A counterweight 33 is suspended from the end of the cantilever 31 by a steel wire rope to balance the trolley's construction load and wind load. The counterweight 33 can be made of materials including concrete, sand, water, or steel, and its actual weight can be calculated and adjusted according to the total load borne by the trolley. The traveling beam 32 is mounted on the cantilever 31, and the lifting trolley 34 is movably connected to the traveling beam 32. The imaging device 5 is mounted on the traveling beam 32. Preferably, there are two cantilever 31s, which can be constructed by welding steel sections and steel plates. The traveling beam 32 uses I-beams that match the wheels of the lifting trolley 34, allowing it to move laterally back and forth under motor drive.

[0038] Furthermore, diagonal braces 4 are provided between the column 12 and the cantilever 31, and at the connection between the column 12 and the support base 11. The diagonal braces 4 are added near the connection between the column 12 and the cantilever 31 and the support base 11 to enhance the stability of the trolley.

[0039] In addition, the lifting trolley 34 includes a trolley body and an electric hoist 35. The trolley body is equipped with wheels that match the track of the traveling beam 32. The trolley body is equipped with an electric hoist 35 with a lifting hook 36. The lifting trolley 34 can drive the electric hoist 35 and the hook 36 to move along the direction of the traveling beam 32. The electric hoist 35 cooperates with the hook 36 to lower or lift the template, thereby realizing the all-round three-dimensional hoisting of the template of the construction section.

[0040] Furthermore, the template construction platform 6 includes a sliding truss 61, a suspended platform 63, and an operating mechanism 64. The suspended platform 63 is connected to the front end of the cantilever 31 via the sliding truss 61, and the lower end of the sliding truss 61 is hinged to the operating mechanism 64. The operating mechanism 64 is connected to the suspended platform 63 via bolts 643. A horizontal hydraulic cylinder 62 is provided on the outer side of the cantilever 31. The tail end of the horizontal hydraulic cylinder 62 is fixedly connected to the cantilever 31, and the front end of the horizontal hydraulic cylinder 62 is movably connected to the sliding truss 61 to allow the sliding truss 61 to move left and right. The sliding truss 61 moves laterally along the cantilever 31 under the telescopic action of two horizontal hydraulic cylinders 62. At the same time, the sliding truss 61 can move up and down in the vertical direction. The horizontal hydraulic cylinders 62 are symmetrically distributed on the outside of the two cantilever 31. The tail end of the horizontal hydraulic cylinder 62 is fixed to the cantilever 31, and the telescopic end is connected to the sliding truss 61 through a sleeve. When the trolley is used for the construction of the central partition wall, the horizontal hydraulic cylinders 62 retract and pull the sliding truss 61 to the center. After reaching the upper part of the central partition wall to be constructed, the extension ends. The sliding truss 61 moves downward in the vertical direction to lower the formwork construction platform to the designated position. The lower part of the formwork construction platform 6, the suspended basket 63, is set on both sides of the operating mechanism 64. The extended part of the suspended basket 63 is a hollow rod with several connecting holes. The outer diameter of the rod is the same as the inner diameter of the hollow rod at both ends of the operating mechanism 64. When the suspended basket 63 is connected to the operating mechanism 64, the high-strength bolt 643 passes through the connecting hole through the rod, thereby realizing the connection between the suspended basket 63 and the operating mechanism 64. When the trolley is used for the construction of the middle partition wall, the bolt 643 is removed to detach the suspended basket 63 from the operating mechanism 64.

[0041] Preferably, the operating mechanism 64 includes a material unloading telescopic plate 641 and a horizontal telescopic cylinder 642. The horizontal telescopic cylinder 642 is used to adjust the template to the designated installation position, and the material unloading telescopic plate 641 is disposed on the basket 63. The operating mechanism 64 adopts a frame structure. The top is set as a feeding telescopic plate 641. Horizontal telescopic cylinders 642 are installed on the two inner side walls. The stabilizing rod 644 is set between the side wall and the cylinder to form a stable triangular structure. Two horizontal telescopic cylinders 642 form a cylinder group. In this embodiment, there is one cylinder group on each of the left and right inner side walls of the operating mechanism 64, and two groups are arranged longitudinally facing each other, for a total of four groups of horizontal telescopic cylinders 642. When fine-tuning the template installation position, the left and right cylinder groups are connected to the outer and inner templates respectively. The cylinders extend and retract in the horizontal direction to adjust the horizontal position of the template. The longitudinal and vertical positions of the template are adjusted by the electric hoist 35 of the lifting trolley 34. Furthermore, when the trolley installs multiple template groups at one time, multiple groups of horizontal telescopic cylinders 642 can be set along the longitudinal direction of the operating mechanism 64. For templates with a length of 10m or more, cylinders should be set at the front, rear and middle positions of the template.

[0042] The discharge telescopic plate 641 is in the form of a square box with a round hole. The round hole in the middle serves as a concrete discharge funnel. A traction device is installed inside the square box. During the overall pouring, the discharge end of the concrete pipe is connected to the round hole funnel. The concrete truck and the trolley move synchronously. The concrete material enters the formwork cavity through the discharge port fixed on the funnel. When the pouring ends, the operating mechanism 64 receives a stop pouring signal. The traction device drives the baffle inside the square box to extend. The excess concrete flowing out under the action of inertia is blocked outside the formwork. Preferably, a stop pouring signal receiving device can be installed in the concrete truck cab or other mechanism for controlling concrete discharge. The traction device works in concert to synchronously control the pouring of the anti-collision wall.

[0043] like Figure 2 As shown, the multi-functional anti-collision wall construction trolley also includes an electrical cabinet 8, which houses the electrical system. The electrical cabinet 8 is installed on the side wall of the column 12. The main circuit of the trolley's electrical system uses 380V AC power at a frequency of 50HZ, and the control circuit is controlled by 380V voltage. All electrical circuits are electrically connected to the electrical cabinet 8.

[0044] Alternatively, as an optional implementation, the imaging device 5 uses a rotatable high-definition camera. The camera position is adjusted by moving the walking beam 32. After the initial hoisting of the template is completed, the imaging device 5 transmits the installation position and on-site image to the technicians. The operating mechanism 64 can be remotely controlled to adjust any improper installation or gaps. When the anti-collision wall concrete is poured, the imaging device 5 sends photos of the pouring inside the template to the terminal computer and analyzes the height of the poured concrete. After the design height is reached, the computer sends a signal to the operating mechanism 64 and the concrete mixer truck cab. The mixer truck stops pouring concrete, and the pouring telescopic plate 641 extends to block the concrete, ensuring that the concrete pouring fully meets the design requirements.

[0045] The construction method of the multi-functional anti-collision wall construction trolley provided by this invention is as follows:

[0046] Step 1: Assemble the construction trolley body 1, hoisting system 3, imaging device 5, and formwork construction platform 6 according to the design drawings and relevant technical data.

[0047] Step 2: Turn on the power and move the trolley body 1 to the construction site using the drive device 7.

[0048] Step 3: Operate the traveling beam 32 and use the lifting trolley 34 to hoist the anti-collision wall template to the designated position for installation.

[0049] Step 4: The sliding truss 61 is lowered to the installed template, the control mechanism 64 is used to adjust the template installation position, and the workers in the suspended platform 63 cooperate to complete other operations.

[0050] Step 5: Move the trolley to the next position and repeat steps 2 and 3 to complete the installation of other segment templates.

[0051] Step Six: Remove the suspended basket 63, connect the concrete pouring pipe outlet to the operating mechanism 64, and the construction trolley and concrete mixer truck will begin pouring operations.

[0052] Step 7: The imaging device 5 sends the pouring image to the terminal computing device. After reaching the design height, the computer issues a stop pouring signal. The operating mechanism 64 and the tank truck receive the signal and end the pouring.

[0053] Step 8: After the concrete reaches the design strength, dismantle the formwork in the reverse order of the formwork installation steps.

[0054] This invention enables the movement of the trolley body 1, the translation of the traveling beam 32, the movement of the lifting trolley 34 and the hoisting of the template, the rotation of the imaging device 5, the stretching of the sliding truss 61 by the horizontal hydraulic cylinder 62, and the operation of the unloading telescopic plate 641 and the horizontal telescopic hydraulic cylinder 642 to be wirelessly remotely controlled from the operating room. On-site technicians can also use the handles of each part to control it individually, making the overall use of the trolley more flexible.

[0055] It should be understood that the above description of specific embodiments of the present invention is only for illustrating the technical approach and features of the present invention, and is intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. However, the present invention is not limited to the specific embodiments described above.
