Description

Technical Field

[0001] This utility model relates to the technical field of integrated transport and erection vehicle, and in particular to an integrated transport and erection vehicle for circular portal steel beams. Background Technology

[0002] Fully enclosed sound barriers are noise reduction facilities composed of continuous enclosed steel structures and high-performance sound insulation materials. They completely enclose noise sources within a sealed space, effectively blocking sound wave propagation and reducing reflection and diffusion. They are particularly suitable for scenarios with stringent noise control requirements, such as urban overpasses, areas near residential areas, or existing railway lines. With accelerating urbanization and increasingly stringent environmental regulations, the demand for such structures on major traffic arteries has increased significantly. However, their complex installation environment and high-altitude operation characteristics pose serious challenges to traditional construction techniques, necessitating innovative solutions.

[0003] In core urban areas, the installation of fully enclosed sound barriers is often located above elevated bridges, with construction heights generally exceeding 30 meters. Furthermore, the space beneath the bridges is often limited by existing roads, railways, or buildings, making it difficult to deploy large ground-based hoisting equipment. Taking a construction section near an existing railway line as an example, the horizontal distance between the bridge deck and the railway line is relatively short. Using conventional cranes would require frequent coordination with the railway department to apply for nighttime "maintenance windows," and would also incur high road occupancy fees and safety risks. In addition, the narrow ground space beneath elevated bridges, coupled with heavy traffic and pedestrian flow, further complicates the feasibility of equipment deployment and material transportation.

[0004] Traditional hoisting processes rely on segmented transportation and high-altitude assembly, resulting in low efficiency, high costs, and numerous safety hazards. For example, each circular steel frame requires individual hoisting and positioning; high-altitude welding and adjustments are time-consuming and labor-intensive, and installation accuracy is difficult to guarantee due to environmental factors such as wind force and visibility on the bridge deck. While existing modular installation equipment or rail transport devices can simplify some processes, most still rely on ground-based workspaces or fixed tracks, making them unsuitable for the special conditions of high-altitude, narrow, and unsupported surfaces. Furthermore, traditional equipment construction often occupies road space, exacerbating traffic congestion and leading to significant social costs and project delays. Utility Model Content

[0005] The purpose of this utility model is to provide a circular portal steel beam transport vehicle to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a circular portal steel beam transport vehicle, comprising a chassis and wheels disposed at the bottom of the chassis, a circular steel frame placement frame disposed at the top of the chassis, two transverse guide rails disposed at the top of the circular steel frame placement frame, a transverse moving block slidably connected to each transverse guide rail, two longitudinal guide rails disposed between the two transverse moving blocks, and a lifting component slidably connected to the two longitudinal guide rails.

[0007] Preferably, the lifting assembly includes a support seat slidably connected to a longitudinal guide rail, a lifting column is provided on the support seat, a support platform is provided at the top of the lifting column, and a limit recess is provided on the support platform.

[0008] Preferably, the support base also has positioning columns that are fixedly connected to the bottom of the support platform through both sides.

[0009] Preferably, the circular steel frame placement frame is provided with several arc-shaped support frames on both sides, and each arc-shaped support frame is provided with several mounting slots. Two clamping blocks are provided in each mounting slot and at the top of the support platform.

[0010] Preferably, the surface of the arc-shaped support frame is provided with an arc-shaped groove that can accommodate a circular steel frame, and clamping grooves are provided on opposite sides of the two clamping blocks.

[0011] Preferably, several telescopic columns are provided on both sides of the chassis, and auxiliary wheels are provided at the bottom of the telescopic columns.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The circular steel frame placement frame serves as the main load-bearing platform for the circular steel frame. The transverse guide rails and transverse moving blocks enable lateral position adjustment during the installation of the circular steel frame, allowing for precise alignment of the installation points and avoiding the time-consuming manual alignment and adjustment. The longitudinal guide rails, in conjunction with the transverse guide rails, enable two-dimensional planar positioning, covering a wider operating range.

[0014] Second, by setting up the lifting components, the support base can be adjusted on the longitudinal guide rail to transport the circular steel frame at different positions to the installation position. The lifting column can lift the support platform, thereby vertically raising and lowering the circular steel frame. The limiting block can prevent the steel frame from horizontal displacement, ensuring zero deviation during the erection process. The positioning column can enhance the anti-tilting ability of the lifting system and ensure the safety of high-altitude operations.

[0015] 3. The arc-shaped support frame is used for multi-point distributed load bearing to avoid stress concentration that could cause steel frame deformation. The clamping blocks can dynamically adapt to steel frames of different diameters, providing active anti-sway protection. The telescopic columns and auxiliary wheels can expand the support surface to improve stability. When moving, they can retract to maintain passability. After expansion, the width reaches 6 meters, greatly improving transportation stability.

[0016] In summary, this equipment can transport and erect multiple steel structure frames at once, significantly shortening the construction period and reducing the risks associated with crane operations at height. Besides the telescopic columns and auxiliary wheels that expand the support surface and enhance stability, all installation operations take place above the circular steel frame and within a 50cm height range. Even in the event of an emergency, the circular steel frame cannot tip over to the ground. The curved support frame provides comprehensive safety protection throughout the construction process.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4As shown, this utility model provides a technical solution: a circular portal steel beam transport vehicle, including a chassis 1 and wheels set at the bottom of the chassis 1. A circular steel frame placement frame 2 is set at the top of the chassis 1. Two transverse guide rails 31 are set at the top of the circular steel frame placement frame 2. A transverse moving block 32 is slidably connected to each transverse guide rail 31. Two longitudinal guide rails 33 are set between the two transverse moving blocks 32. Lifting components are slidably connected to the two longitudinal guide rails 33.

[0024] The circular steel frame placement frame 2 is used as the main load-bearing platform for the circular steel frame. The transverse guide rail 31 and the transverse moving block 32 can realize the transverse position adjustment during the installation of the circular steel frame, which can accurately align the installation point and avoid the time-consuming manual operation and alignment adjustment. The longitudinal guide rail 33 can be combined with the transverse guide rail 31 to realize two-dimensional plane positioning and cover a larger working range.

[0025] Furthermore, the lifting assembly includes a support base 41 slidably connected to the longitudinal guide rail 33, a lifting column 42 is provided on the support base 41, a support platform 43 is provided at the top of the lifting column 42, and a limit recess 44 is provided on the support platform 43.

[0026] Furthermore, positioning columns 45, which are fixedly connected to the bottom of the support platform 43, are also inserted through both sides of the support base 41.

[0027] The support base 41 can be adjusted on the longitudinal guide rail 33 to transport the circular steel frame at different positions to the installation position. The lifting column 42 can lift the support platform 43, thereby vertically raising and lowering the circular steel frame. The limiting recess 44 can prevent the steel frame from horizontal displacement, ensuring zero deviation during the erection process. The positioning column 45 can enhance the anti-tilting ability of the lifting system and ensure the safety of high-altitude operations.

[0028] Furthermore, several arc-shaped support frames 5 are provided on both sides of the circular steel frame placement frame 2. Several installation slots are provided on each arc-shaped support frame 5. Two clamping blocks 6 are slidably connected in each installation slot and at the top of the support platform 43.

[0029] Furthermore, the surface of the arc-shaped support frame 5 is provided with an arc-shaped groove that can accommodate the circular steel frame, and the two clamping blocks 6 are provided with clamping grooves on opposite sides. Rubber pads are provided in the clamping grooves to prevent wear on the anti-corrosion layer of the circular steel frame.

[0030] Furthermore, several telescopic columns 7 are provided on both sides of the chassis 1, and auxiliary wheels 8 are provided at the bottom of the telescopic columns 7.

[0031] The arc-shaped support frame 5 is used for multi-point distributed load bearing to avoid stress concentration that could cause steel frame deformation. The clamping block 6 can dynamically adapt to steel frames of different diameters and provide active anti-sway protection. The telescopic column 7 and auxiliary wheel 8 can expand the support surface to improve stability. When moving, they can retract to maintain passability. After expansion, the width reaches 6 meters, which greatly improves transportation stability.

[0032] Working principle: First, a circular portal steel beam transport vehicle is moved to the working position. In use, the first step involves extending the auxiliary wheels 8 via the telescopic column 7 for support, then hoisting the circular steel frame into the arc-shaped groove on the arc-shaped support frame 5, and clamping it with the clamping block 6 within the mounting groove. The second step involves moving the entire vehicle to the desired location for the circular steel frame via the wheels. The third step involves moving the support base 41 along the longitudinal guide rail 33 until it is directly beneath the circular steel frame. The fourth step involves activating the lifting column 42 to raise the support platform 43, causing the limiting recess 44 to engage beneath the circular steel frame, and then clamping the circular steel frame with the clamping block 6 on the support platform 43. Fifth step, the lifting column 42 continues to lift the support platform 43 until the circular steel frame is disengaged from the arc groove. Sixth step, the lateral moving block 32 moves on the lateral guide rail 31, driving the longitudinal guide rail 33 to move laterally, thereby adjusting the lateral position of the circular steel frame. Seventh step, the support seat 41 continues to move on the longitudinal guide rail 33 until the circular steel frame is above the installation position. Then, the lifting column 42 lowers the support platform 43 so that the circular steel frame is in the installation position. Eighth step, after the first circular steel frame is installed, the whole unit is moved backward by the wheels. Then, steps three to seven above are repeated. This completes the use of a circular portal steel beam transport vehicle.

[0033] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
