[0002] In highway engineering projects, there are numerous bridge projects. These bridges are designed with crash barriers along their edges. These crash barriers are reinforced concrete structures, primarily constructed using specially designed formwork through in-situ casting. Formwork installation is a critical process and operation during construction because it is located at the edge of the bridge, constituting high-altitude work and posing significant safety risks.

[0003] Chinese invention patent CN116201038A discloses a multi-functional anti-collision wall construction trolley, capable of monitoring the entire process of formwork installation, dismantling, and concrete pouring. The trolley body and hoisting system have sufficient working space, and the concrete pouring truck can move synchronously with the trolley body, reducing on-site personnel requirements. The trolley's load capacity can be controlled by disassembling the construction basket. The overall structure of the trolley has reasonable stress distribution, making hoisting convenient, and the trolley's self-propelled movement and braking are stable. However, this trolley lacks steering functionality, making it unsuitable for complex road conditions, and its stability is insufficient. Utility Model Content

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. However, it should not be construed that the scope of the subject matter of the present invention is limited to the following embodiments. Any modifications, substitutions and alterations made based on ordinary technical knowledge and conventional means in the art without departing from the above-described technical concept of the present invention are included within the scope of the present invention.

[0027] Reference Figure 1 The self-propelled anti-collision wall formwork construction trolley includes a modular trolley support 9, a trolley system A, a walking system B, and a steering system C connected to the trolley support 9 respectively. The trolley is operated by wire control, driven by the walking system B, steered by the steering system C, and lifted by the trolley system A. A formwork lifting trolley D is also installed on the trolley to move and lift the formwork.

[0028] Reference Figure 2 and Figure 3 The trolley frame 9 adopts a modular design. The front and rear columns 92 are each connected to the main crossbeams 91 as a whole, and the middle is reinforced by the gantry 94. The main crossbeams 91 adopt a cantilever structure design with an anti-bending strap on the upper part, thus avoiding the use of the diagonal bracing structure of the columns 92, improving the working space. The use of the upper anti-bending structure reduces the cross-sectional size of the main crossbeams 91, increasing the rigidity of the main crossbeams 91 while reducing the weight of the trolley. The trolley support 9 adopts a modular design and is connected by bolts. It is mainly composed of the base frame 93, gantry 94, columns 92, and main crossbeams 91, and is the main body of the trolley.

[0029] The base frame 93 is a horizontal frame structure welded from I-beams, including longitudinal beams, cross beams, bearing supports for the drive wheel axle, drive reducer mounting device, steering seat, etc. One end of the longitudinal beam has a bearing support mounting hole, and the bearing support is fixed in the bearing support mounting hole of the longitudinal beam by a reinforcing plate. Two cross beams are set at the inner end of the base frame, which mainly serve to reinforce the longitudinal beam and fix the drive reducer mounting plate. The steering seat is used to install the steering shaft.

[0030] The gantry 94 adopts a frame structure design, mainly serving to reinforce the column 92;

[0031] The column 92 mainly adopts the design of I-beams, with a total of four columns, two in the front and two in the back. The front column is connected by two connecting rods to form the front frame, and the rear column is connected by two connecting rods to form the rear frame. The front and rear frame components are connected into one piece by the gantry.

[0032] The main crossbeam 91 is designed with I-beams, with an anti-bending structure on the upper part and a basket limiting slot at the end. The main crossbeam is divided into a front main crossbeam and a rear main crossbeam, which are installed on the top of the front column and the rear column, respectively.

[0033] Reference Figure 4 The suspended platform 1 is the working component of the trolley. It is suspended from one end of the main crossbeam 91 of the trolley support 9 by an electric hoist 12 and its lifting and lowering are controlled by a handheld wired controller. During operation, it is suspended on the outside of the bridge. The other end of the crossbeam 9 is equipped with a counterweight 5. The suspended platform 1 and its working load are balanced with the counterweight. The working load of the suspended platform includes the weight of two workers and related tools. During construction, the formwork lifting crane D installed on the main crossbeam 91 is used to lift the formwork. To ensure the stability of the suspended platform 1, a suspended platform limiter 2 is used to limit its horizontal movement. The horizontal limiter 2 passes through the limiter slot of the main crossbeam 9 and can move up and down with the suspended platform 1. Sufficient counterweight should be attached before construction.

[0034] During construction, a handheld wired controller is used to operate a trolley carrying a suspended basket 1 and a counterweight 5 to the construction section. Then, workers use a special ladder to go into the suspended basket 1. The template lifting crane D then lifts the crash barrier templates piece by piece to the installation position of the crash barrier. The outer templates are positioned, connected and fixed by workers on the suspended basket, while the inner templates are installed by workers on the bridge deck.

[0035] Reference Figure 5 and Figure 6 The trolley has a self-driving function and is operated by wired remote control. It is driven by the electric reducer 7 and driven by the connecting rod by the screw reducer 18. The trolley has a steering function. The steering wheel 4 is mounted on the base frame 93 through the steering shaft 15 and is pushed by the steering arm 16 to rotate around the center hole of the ear plate of the base frame 93. The two steering arms 16 are connected by the steering linkage 17, so that the two steering wheels 4 are synced and the steering force is linked. The steering linkage 17 is pushed and pulled by the screw reducer 18 to move left and right, thereby driving the steering wheel 4 to swing clockwise or counterclockwise.

[0036] Reference Figure 7 The trolley has a formwork lifting function. The formwork lifting trolley consists of a mobile trolley 6 and a lifting winch 10. The mobile trolley 6 consists of a mobile trolley 61 and a trolley beam 62. The mobile trolley 61 is designed with two flanged rollers, which are used to limit the installation on the main crossbeam 91. The mobile trolley 61 is driven by an electric reducer, which allows it to move back and forth on the main crossbeam 91. The formwork lifting winch 10 is mounted on the trolley beam 62 as a lifting and hoisting device for formwork installation.

[0037] The walking system B consists of a drive reducer 7, drive wheels 14, a rotating shaft 11, and a chain drive 13, providing the trolley with the power to move. The low-speed (17 r / m) drive reducer 7 drives the rotating shaft 11 through the chain 13, which in turn drives the drive wheels 14 to rotate, thus enabling the trolley to move back and forth. The drive wheels are solid rubber wheels, which can adapt to complex ground conditions.

[0038] The steering system C consists of steering linkage 17, steering arm 16, steering shaft 15, steering wheel 4, etc. The steering working principle of the steering system is that the screw reducer 18 pushes the steering linkage 17, the steering linkage 17 then links the left and right steering arms 16, and then pushes the steering shaft 15 to rotate, thereby realizing the deflection of the steering wheel 4. The lead screw reducer 18 consists of a lead screw reducer, a nut seat, and a rotary mounting base. The lead screw reducer 18 is driven by a motor to rotate the lead screw. The nut seat is installed on the lead screw through a rectangular threaded hole. The rotating lead screw drives the nut seat to move back and forth along the lead screw. The rotary mounting base hinges the lead screw reducer 18 to the base frame. The steering linkage adopts a square tube design, with a steering gear connecting seat in the middle for installing the steering gear nut seat. The forward and backward movement of the nut seat drives the steering linkage to move left and right. The two ends of the steering linkage are designed with open slots for connecting the left and right steering arms. The steering arms are the providers of steering torque, driven by the steering linkage to rotate, which in turn drives the steering shaft to rotate. The steering shaft is reinforced and welded from components such as a vertical rotating sleeve, a transverse half-shaft, and a steering arm connecting plate. The vertical rotating sleeve is installed on the base frame through a pin and can rotate horizontally around the vertical axis. The transverse half-shaft is used to install the steering wheel and is driven by the steering arm to rotate horizontally around the vertical axis, realizing the steering of the steering wheel.

[0039] The suspended platform system A consists of several parts, including the suspended platform 1, the suspended platform lifting hoist 12, and the limiting frame 2. It serves as the working platform for the trolley, providing basic functions for the trolley. The suspended platform 1 is suspended from the end of the trolley bracket 9 by the suspended platform lifting hoist 12, which provides the lifting power for its up-and-down movement. Since the suspended platform is susceptible to horizontal swaying due to wind, a limiting frame 2 is designed to secure it. The lower end of the limiting frame is bolted to the upper part of the suspended platform, and the upper end passes through the platform limiting slot at the end of the main crossbeam 91. It rises and falls together with the suspended platform, simultaneously controlling its horizontal swaying.

[0040] The formwork lifting trolley D consists of a mobile trolley 6 and a formwork lifting winch 10, and is the formwork lifting and hoisting equipment used during the installation of the crash barrier formwork. The mobile trolley 6 consists of a mobile trolley 61 and a trolley beam 62. The mobile trolley 61 is designed with two rollers and is mounted on the main crossbeam 91 via the rollers. The mobile trolley 61 is driven by an electric reducer, allowing it to move back and forth on the main crossbeam 91. The formwork lifting winch 10 is mounted on the trolley beam 62 and mainly provides lifting and hoisting equipment for the installation of the crash barrier formwork.

[0041] The electrical control system E consists of an electrical control cabinet, remote controller, etc., providing power to the entire trolley and controlling its movement and steering. The entire machine is operated via a wired remote controller, which is convenient and provides a visual interface.

[0042] The invented trolley is specially designed and manufactured by a processing plant. After passing inspection, it is transported to the construction site for installation, which proceeds from bottom to top. The installation of the suspended platform is crucial. The platform and its limit frame should be installed on the bridge deck. After verifying the safety of all connections, the trolley is driven close to the crash barrier to be constructed, ensuring the platform is suspended outside the bridge. Then, the electric hoist is operated to slowly lower the platform to its lowest position and then raise it again. This process is repeated multiple times to ensure there is no jamming, and the connections are checked to ensure safety. During construction, workers must wear safety ropes.

[0043] The invented trolley is operated by wire control, driven by an electric reducer and steered by a screw reducer driving a connecting rod. The suspended platform is the working component of the trolley, suspended from one end of the main crossbeam by an electric hoist and raised and lowered by a handheld wired controller. During operation, it is suspended on the outside of the bridge, with a counterweight mounted on the other end of the crossbeam. The suspended platform and its working load are balanced with the counterweight. The working load of the suspended platform includes the weight of two workers and related tools. During construction, a formwork lifting trolley installed on the main crossbeam lifts the formwork. To ensure the stability of the suspended platform, a platform limiting frame is used to limit its horizontal movement. The horizontal limiting frame passes through the limiting slot of the main crossbeam and can move up and down with the suspended platform. Sufficient counterweight should be mounted before construction.

[0044] During construction, a handheld wired controller is used to operate a trolley carrying a suspended basket and counterweight to the construction section. Then, workers use a special ladder to go into the suspended basket. The formwork lifting trolley then lifts the crash barrier formwork piece by piece to the installation position of the crash barrier. The outer formwork is positioned, connected and fixed by workers on the suspended basket, while the inner formwork is installed by workers on the bridge deck.

[0045] This trolley allows for the installation of formwork on both the inside and outside of the crash barrier. Furthermore, the trolley's lifting equipment enables mechanized formwork installation, reducing labor intensity and safety risks for workers.
