[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] This application provides a formwork hoisting vehicle for highway bridge crash barriers, which can solve the problems in related technologies where large lifting equipment is expensive and cannot meet the requirements of good parking environment for high-height bridges, river-crossing bridges, and deep valley bridges, making hoisting construction difficult.

[0027] Currently, the construction of crash barriers for highway bridges faces several challenges. Firstly, while truck cranes are used to assist in lifting formwork, this method requires large lifting equipment, resulting in high costs and inconvenience. Secondly, it necessitates good traffic conditions beneath the bridge. For high-altitude bridges, bridges spanning rivers, and bridges in deep valleys, suitable parking and installation conditions for auxiliary tools are often unavailable. Furthermore, lifting operations on the bridge deck would obstruct existing construction access. Therefore, a solution is proposed to improve the construction efficiency of bridge crash barriers while ensuring safety and reducing costs. This solution involves designing a trolley capable of free movement on the bridge. Secondly, a lifting device is installed on the trolley to stably lift the formwork. Finally, a component for adjusting direction and angle is designed on the trolley, allowing it to change direction during movement and adjust the lifting angle during the lifting process. This addresses the problems of high costs associated with large lifting equipment and the inability to provide adequate parking conditions for high-altitude bridges, bridges spanning rivers, and bridges in deep valleys, hindering the lifting operation.

[0028] refer to Figure 1-7 ,in Figure 1 This is a side view structural schematic diagram of the hoisting vehicle provided in the embodiments of this application; a highway bridge crash barrier formwork hoisting vehicle includes a vehicle body 1, which is used to transfer formwork 2 on the bridge, and the vehicle body 1 includes two right-angled triangular frames 11 connected by a crossbeam, and the distance between the two right-angled triangular frames 11 gradually decreases in the horizontal direction until they intersect, and a steering component 4 for controlling the movement direction of the vehicle body 1 is provided at the intersection; a hoisting component 3 is provided on the crossbeam to adjust the position of the formwork 2 and control the movement direction of the vehicle body 1 during the hoisting and fixing process.

[0029] With this structural design, the vehicle body 1 forms the foundation of the entire crane, primarily used for transporting the formwork 2 on bridges. It utilizes high-strength, lightweight alloy materials to reduce overall weight and improve movement efficiency. The horizontal spacing between the two right-angled triangular frames 11 gradually decreases until they intersect, allowing for effective operation in narrow bridge environments and ensuring the vehicle body 1 can smoothly pass over bridge edges without obstructing other work. The lifting assembly 3 is a crucial component for lifting and securing the formwork 2, ensuring stable and safe lifting and placement during its installation. The steering assembly 4, located at the intersection of the two right-angled triangular frames 11, controls the movement direction of the vehicle body 1. This design allows for precise directional adjustments during lifting and movement, making the installation of the formwork 2 more flexible and efficient. This miniaturized design not only reduces equipment costs but also improves construction efficiency, adapting to the economic requirements of modern construction and enhancing compatibility with different on-site construction environments. This solves the problem in related technologies that the cost of large lifting equipment is high, and that it is difficult to install and construct crash barriers in areas with large heights, such as bridges spanning rivers and deep valleys, due to the inability to provide adequate parking environments.

[0030] In some preferred embodiments, the hypotenuses of the two right-angled triangular frames 11 are fixedly connected by a plurality of first crossbeams 12 at equal intervals, and a plurality of second crossbeams 13 are provided between the corresponding vertical sides of the two right-angled triangular frames 11.

[0031] Through this structural design, the vehicle body 1 is mainly composed of two right-angled triangular frames 11, which effectively improves the stability and load-bearing capacity of the structure. The use of two right-angled triangular frames allows for a reasonable distribution of mechanical forces, especially under stress, effectively dispersing weight and stress and enhancing overall stability. The right-angled triangular frames 11 are spaced apart, with the spacing gradually decreasing along the horizontal direction. This design lowers the center of gravity, providing better anti-overturning properties, and facilitates subsequent counterweight and balance adjustments. The first crossbeam 12 connects the hypotenuses of the two right-angled triangular frames 11, providing enhanced lateral stability and support through equal spacing. It also serves as a platform for subsequent installation of auxiliary lifting equipment. The second crossbeam 13 is positioned between the corresponding vertical sides of the two right-angled triangular frames 11, primarily to enhance the overall structural stability and prevent deformation of the right-angled triangular frames 11 under stress. This vehicle body design, utilizing right-angled triangular frames 11, the first crossbeam 12, and the second crossbeam 13, improves the structural strength and stability of the lifting vehicle, contributing to superior performance in complex construction environments and ensuring the safe and efficient lifting of the bridge formwork 2.

[0032] In some preferred embodiments, a first hoisting rod 5 perpendicular to the first crossbeam 12 is provided on the first crossbeam 12, and one end of the first hoisting rod 5 is fixed to the second crossbeam 13 located at the top; the end of the first hoisting rod 5 fixed to the second crossbeam 13 is connected to a second hoisting rod 6, and the second hoisting rod 6 is perpendicular to the second crossbeam 13; the hoisting assembly 3 is fixed to the first hoisting rod 5 and the second hoisting rod 6.

[0033] With this structural design, the first lifting rod 5 is positioned perpendicular to the first crossbeam 12, with one end fixed to the top second crossbeam 13. This vertical arrangement effectively transfers weight and ensures that the forces generated during lifting operations are transmitted downwards to the entire vehicle body structure. The second lifting rod 6 is connected to the first lifting rod 5 and is perpendicular to the second crossbeam 13. This design facilitates the subsequent installation of lifting devices; the lifting assembly 3, fixed to the first and second lifting rods 5 and 6, forms a three-dimensional lifting system. Its structural design possesses excellent load-bearing capacity and stability, capable of withstanding the dynamic impacts generated during lifting. These designs optimize the force transmission path, effectively reducing stress concentration during lifting operations, and effectively resist vibrations and bumps during lifting, thus improving the dynamic stability of the entire lifting system.

[0034] In some preferred embodiments, the hoisting assembly 3 includes a winch 31, fixed pulleys 32 and wire ropes 33; the two fixed pulleys 32 are respectively located at both ends of the top of the second hoisting installation rod 6, the winch 31 is located on the first hoisting installation rod 5, and the wire ropes 33 are respectively connected to the winch 31 and the two fixed pulleys 32 for hoisting and fixing the template 2.

[0035] With this structural design, the winch 31 is installed on the first lifting rod 5, responsible for controlling the lifting and lowering of the formwork 2 by winding and releasing the wire rope 33. The winch 31 should have sufficient lifting capacity to support the weight of the formwork 2. In addition, the winch 31 should be equipped with an electric or manual operating device for easy and precise control by construction personnel. Two fixed pulleys 32 are respectively installed at both ends of the top of the second lifting rod 6. The arrangement of the fixed pulleys 32 allows the wire rope 33 to run along a predetermined trajectory, reducing friction and energy loss. The main function of the fixed pulleys 32 is to guide the movement of the wire rope 33 and provide a fulcrum, effectively changing the direction of force and making the lifting process more flexible. The wire rope 33 connects the winch 31 and the two fixed pulleys 32 respectively. Its material selection must have high strength and wear resistance to ensure that it can withstand additional tension and wear during the lifting process. During the lifting process, the winch 31 starts to work, the wire rope 33 is wound up, and the fixed formwork 2 is lifted upwards. Meanwhile, guided by the fixed pulley 32, the direction of the force can be adjusted appropriately; this structure enables the safe and effective hoisting of the formwork 2. This design not only improves construction efficiency but also enhances operational safety.

[0036] In some preferred embodiments, one end of the wire rope 33 is connected to the output of the winch 31, and the other end is provided with a hook 34; the template 2 is provided with a lifting ring for the hook 34 to connect to.

[0037] With this structural design, the wire rope 33 is connected at one end to the output section of the winch 31, and the other end is equipped with a hook 34. The hook 34, as a key component connecting the hoisting system and the formwork 2, is responsible for transmitting the tension of the wire rope 33 to the formwork 2. The formwork 2 is equipped with a specially designed lifting ring for connecting the hook 34. This lifting ring is designed to facilitate the hoisting of the hook 34 and should meet the load requirements to ensure that it can bear the weight of the formwork 2 and remain stable during the hoisting process.

[0038] In some preferred embodiments, the bottom end of the second hoisting rod 6, away from the vehicle body 1, is provided with a vertical plate 7 for limiting the wire rope 33.

[0039] With this structural design, a vertical plate 7 is provided at the bottom end of the second lifting rod 6, away from the vehicle body 1. The purpose of this vertical plate 7 is to effectively limit the movement of the wire rope 33, ensuring stability during the lifting process. During lifting, the wire rope 33 may experience slight vibrations. The vertical plate 7, installed at the bottom of the second lifting rod 6, forms a limiting mechanism. The vertical plate 7 restricts the movement of the wire rope 33, preventing improper operation caused by excessive stretching or deviation from the trajectory of the wire rope 33 during lifting by setting a fixed working range. This avoids slackness or misalignment of the wire rope 33 during lifting, thereby improving the overall safety of the system.

[0040] In some preferred embodiments, the bottom of each of the two right-angled triangular frames 11 is provided with a first pulley 8, and the first pulleys 8 are connected to each other by a synchronous shaft 9.

[0041] With this structural design, the first pulley 8 is typically made of high-strength material to ensure it does not deform or break under heavy loads. The diameter and width of the first pulley 8 are rationally designed to meet the needs of various lifting operations. The first pulleys 8 are connected by a synchronous shaft 9 to ensure that the two first pulleys 8 work in coordination during operation. This avoids asynchrony between the pulleys, thereby improving the efficiency and reliability of the lifting system.

[0042] In some preferred embodiments, the first pulley 8 is located at the bottom of the right-angled triangular frame 11 near one end of the second hoisting rod 6, and a mounting plate is provided between the other bottom ends of the right-angled triangular frame 11; the steering assembly 4 is located on the mounting plate.

[0043] This structural design, with the first pulley 8 positioned at the bottom of the right-angled triangular frame 11 near the second lifting rod 6, helps reduce the pulley path during lifting operations, improving operational intuitiveness and efficiency. A mounting plate is located at the other bottom end of the right-angled triangular frame 11. This mounting plate helps to evenly distribute the load applied to the first pulley 8 and the adjusting assembly 4 across the frame, reducing the risk of damage caused by localized stress. The adjusting assembly 4 allows for flexible adjustment of the lifting angle during the lifting process, which is particularly important for ensuring accurate placement of the load.

[0044] In some preferred embodiments, the steering assembly 4 includes a second pulley 41, a rotating rod 42, and a steering wheel 43; the rotating rod 42 is vertically fixed to the mounting plate, the bottom of the rotating rod 42 is connected to the second pulley 41, and the top of the rotating rod 42 is connected to the steering wheel 43.

[0045] Through this structural design, the second pulley 41, as the primary device for changing the direction of the load, can effectively guide the trajectory of the suspended object, reducing deviations caused by improper operation. The rotating rod 42 is vertically fixed to the mounting plate, its bottom connected to the second pulley 41, and its top connected to the steering wheel 43, forming a linkage mechanism. By rotating the steering wheel 43, the second pulley 41 can be moved directly, thus flexibly adjusting the direction of the load. The steering wheel 43 serves as the operator's direct control interface, making direction adjustment simple. Manually rotating the steering wheel 43 allows for quick and precise direction adjustment of the load; for additional information, an optional rotation angle indicator can be added to help the operator understand the current operating status in real time, improving accuracy.

[0046] In some preferred embodiments, the steering wheel 43 is provided with an anti-slip ring sleeve.

[0047] This structural design typically utilizes materials with a high coefficient of friction, such as polyurethane or rubber, to effectively increase contact friction with the hand and prevent slippage during operation. The anti-slip ring can be designed to fit the outer rim of the steering wheel 43 and provide a certain thickness to ensure a good grip when rotating the steering wheel 43. The introduction of the anti-slip ring improves the operator's control precision when rotating the steering wheel 43 and reduces misoperations caused by hand slippage. This is particularly important in lifting operations requiring precise steering.

[0048] The beneficial effects of this utility model include:

[0049] The vehicle body 1 is the basic structure of the entire crane, mainly used for transporting formwork 2 on bridges. It is made of high-strength, lightweight alloy materials to reduce overall weight and improve movement efficiency. The lifting assembly 3 is a key component for lifting and securing formwork 2, ensuring stable and safe lifting and placement of the formwork during the lifting process. The steering assembly 4 is used to adjust the position of formwork 2 during lifting and control the direction of movement of the vehicle body 1. Furthermore, it can be operated manually or automatically. This structure, with its miniaturized design, not only reduces equipment costs but also improves construction efficiency, meeting the economic requirements of modern construction and enhancing compatibility with the on-site construction environment. This solves the problems in related technologies regarding the lifting and construction of crash barriers, where large lifting equipment is expensive and, for high-height bridges, river-crossing bridges, and deep valley bridges, cannot provide suitable parking environments, making lifting and construction difficult.
