Abstract
Description
Technical Field
[0001] This utility model relates to the field of precast beam transportation technology, and in particular to a precast beam moving and steering device. Background Technology
[0002] In the field of construction engineering, precast beams, as an important structural component, are widely used in bridges, buildings, and other projects. They have many advantages, such as high manufacturing precision, fast construction speed, and stable quality. However, in actual engineering applications, the movement and turning of precast beams has always been a challenging problem. Because precast beams are usually large and heavy, traditional methods of movement and turning are not only inefficient but also pose significant safety hazards, easily causing damage to the precast beams themselves, as well as to surrounding personnel and equipment.
[0003] Existing technology, such as a utility model of a steel reinforcement transfer flatbed truck for precast box girder yards, authorized announcement number CN222946756U, involves steering by swinging the steering wheels due to the speed difference between the two drive wheels, and the truck moving linearly when the speeds of the two drive wheels are synchronized.
[0004] Currently, there is a lack of a precast beam moving and steering device that can synchronously turn the wheels at the four corners of the load plate by operating hydraulic rods, thus facilitating the moving and steering of the precast beam.
[0005] Therefore, in order to address the above problems, a precast beam moving and steering device is proposed to solve them. Summary of the Invention
[0006] This invention addresses the shortcomings of existing technologies by developing a precast beam moving and steering device. By employing loading and unloading components, the precast beam can be easily fixed to enable its movement. By using hydraulic rods to achieve synchronous wheel steering, the precast beam can be easily moved and steered.
[0007] The technical solution to the problem solved by this utility model is as follows: This utility model provides a precast beam moving and steering device, comprising: a vehicle body assembly, the vehicle body assembly including a load plate for supporting the precast beam and serving as the mounting base for other components; mounting columns connected to the four corners of the load plate, each mounting column connected to a mounting shaft; and a vertical shaft connected to the lower center of the load plate; four wheel assemblies rotatably connected to their respective mounting shafts; and a power assembly rotatably connected to the vertical shaft, with the four wheel assemblies rotatably connected to the power assembly. The mounting columns and the load plate are fixedly connected by high-strength bolts to ensure a stable and reliable connection. The mounting shafts are rotatably connected to the wheel assemblies using bearings, allowing the wheel assemblies to rotate flexibly. The vertical shaft is fixedly connected to the lower center of the load plate by welding to ensure the stability of the overall structure and is rotatably connected to the power assembly to achieve the steering function.
[0008] As an optimization, the wheel assembly includes a cylindrical shaft rotatably connected to a corresponding mounting shaft. The cylindrical shaft is connected to a wheel seat, and the wheel seat bearings connect to the wheel axle. Wheels are mounted at both ends of the wheel axle, and the wheel seat is connected to a power arm. The power arm is connected to a power assembly, which provides power to drive the power arm's movement, thereby enabling the wheel seat, wheel axle, and wheels to rotate and steer. The rotatable connection between the cylindrical shaft and the mounting shaft ensures that the wheel assembly can be flexibly adjusted for rotation as needed. The wheels mounted at both ends of the wheel axle are made of high-strength, wear-resistant material, capable of bearing the weight of the precast beam and moving stably on different surfaces.
[0009] As an optimization, the power assembly includes a power rod rotatably connected to the vertical shaft. The power rod has symmetrical straight grooves, each containing a power block. Each power block is connected to a parallel rod, and the power arm is rotatably connected to the corresponding parallel rod. The symmetrical straight grooves on the power rod provide a stable sliding track for the power blocks. The symmetrical power blocks slide within the grooves, causing the connected parallel rods to swing. The swinging motion of the parallel rods is further transmitted to the power arm via a rotatable connection, enabling the power arm to swing along a predetermined trajectory. This ensures the stability of power transmission, making the device more flexible and reliable during movement and turning.
[0010] As an optimization, the lower side of the carrying plate is connected to symmetrical side shafts, two side shafts are rotatably connected to mounting seats, two power blocks are rotatably connected to rings, and at least one mounting seat is connected to a hydraulic rod, the piston rod of which is connected to the corresponding ring. The extension and retraction of the hydraulic rod can drive the ring to move. Since the ring is rotatably connected to the power blocks, the movement of the ring will cause the power blocks to slide in the straight groove, which in turn will drive the power arm to swing through the parallel rod.
[0011] As an optimization, one of the mounting bases connects to a counterweight telescopic rod, the telescopic end of which is connected to a corresponding ring. The extension and retraction of the balancing hydraulic rod causes a change in the center of gravity of the device.
[0012] As an optimization, the vertical axis and the symmetrical side axis are respectively connected to reinforcing plates. The reinforcing plates are made of high-strength materials, which effectively enhances the connection strength between the vertical axis and the side axis, and improves the stability and reliability of the entire device during movement and turning.
[0013] As an optimization, a loading and unloading assembly is also included, comprising a placement slot installed at the upper center of the carrying plate. The cross-section of the placement slot is adapted to the dimensions of the precast beam, enabling stable placement of the precast beam and preventing slippage during movement and turning. The inner surface of the placement slot is textured with anti-slip material, further enhancing the stability of the precast beam during placement. Simultaneously, the edges of the placement slot are rounded to prevent scratches or other injuries to operators during loading and unloading of the precast beam.
[0014] As an optimization, a set of retaining rings is connected to each side of the placement slot. The retaining rings are made of a robust and durable metal material. Ropes are threaded through the retaining rings to secure the precast beam.
[0015] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects: (1) By using parallel rods arranged in parallel, this utility model realizes that when the hydraulic rod extends or retracts, the parallel rods drive the power arm to swing, so that all the wheels can turn synchronously.
[0016] (2) The placement groove in the loading and unloading assembly of this utility model is adapted to the size of the precast beam, and has anti-slip texture inside and rounded edges, which can not only securely place the precast beam and prevent it from slipping, but also avoid causing injury to the operator.
[0017] (3) The telescopic rod of this utility model balances the hydraulic rod and causes a change in the center of gravity of the device. Attached Figure Description

[0026] like Figures 1 to 5As shown in Embodiment 1: A precast beam moving and steering device includes: a vehicle body assembly 2, which includes a load plate 21 for supporting the precast beam and serving as the mounting base for other components. Mounting columns 22 are connected to the four corners of the load plate 21, and each mounting column 22 is connected to a mounting shaft 23. A vertical shaft 26 is connected to the lower center of the load plate 21; four wheel assemblies 3 are rotatably connected to their respective mounting shafts 23; and a power assembly 4 is rotatably connected to the vertical shaft 26. The four wheel assemblies 3 are rotatably connected to the power assembly 4. The mounting columns 22 and the load plate 21 are fixedly connected by high-strength bolts to ensure a stable and reliable connection. The mounting shafts 23 are rotatably connected to the wheel assemblies 3 using bearings, allowing the wheel assemblies 3 to rotate flexibly. The vertical shaft 26 is fixedly connected to the lower center of the load plate 21 by welding to ensure the stability of the overall structure and is rotatably connected to the power assembly 4 to achieve the steering function.
[0027] The wheel assembly 3 includes a cylindrical shaft 31, which is rotatably connected to the corresponding mounting shaft 23. The cylindrical shaft 31 is connected to a wheel seat 33, and the wheel seat 33 is bearing-connected to a wheel axle 34. Wheels 35 are respectively mounted on both ends of the wheel axle 34. The wheel seat 33 is connected to a power arm 32. The power arm 32 is connected to a power assembly 4, which provides power to drive the power arm 32 to move, thereby enabling the wheel seat 33, wheel axle 34, and wheels 35 to rotate and steer. The rotatable connection between the cylindrical shaft 31 and the mounting shaft 23 ensures that the wheel assembly 3 can be flexibly adjusted for rotation as needed. The wheels 35 mounted on both ends of the wheel axle 34 are made of high-strength wear-resistant material, capable of bearing the weight of the precast beam and moving stably on different surfaces.
[0028] The power assembly 4 includes a power rod 44, which is rotatably connected to the vertical shaft 26. The power rod 44 has symmetrical straight grooves 47, each containing a power block 45. Each power block 45 is connected to a parallel rod 46, and the power arm 32 is rotatably connected to the corresponding parallel rod 46. The symmetrical straight grooves 47 on the power rod 44 provide a stable sliding track for the power blocks 45. The symmetrical power blocks 45 slide within the straight grooves 47, causing the connected parallel rods 46 to swing. The swinging motion of the parallel rods 46 is further transmitted to the power arm 32 via a rotatable connection, enabling the power arm 32 to swing along a predetermined trajectory. This ensures the stability of power transmission, making the device more flexible and reliable during movement and turning.
[0029] The lower side of the carrier plate 21 is connected to symmetrical side shafts 24. Two side shafts 24 are rotatably connected to mounting bases 41, and two power blocks 45 are rotatably connected to rings 43. At least one mounting base 41 is connected to a hydraulic rod 42, and the piston rod of the hydraulic rod 42 is connected to the corresponding ring 43. The extension and retraction of the hydraulic rod 42 can drive the ring 43 to move. Since the ring 43 is rotatably connected to the power blocks 45, the movement of the ring 43 will cause the power blocks 45 to slide within the straight groove 47, thereby driving the power arm 32 to swing via the parallel rod 46.
[0030] The vertical shaft 26 and the symmetrical side shaft 24 are respectively connected to the reinforcing plate 25. The reinforcing plate 25 is made of high-strength material, which effectively enhances the connection strength between the vertical shaft 26 and the side shaft 24, and improves the stability and reliability of the entire device during movement and turning.
[0031] The workflow of this embodiment is as follows: When steering is required, the hydraulic rod 42 is extended or retracted, causing the ring 43 to swing. The ring 43 then causes the power block 45 to swing and move along the straight groove 47. The power block 45 causes the power rod 44 to swing, which in turn causes the ring 43 to swing. The ring 43 then causes the hydraulic rod 42 to swing, which in turn causes the mounting base 43 to rotate. The power block 45 then causes the parallel rod 46 to swing, which in turn causes the power arm 32 to swing, thus enabling the wheel assembly 3 to rotate around the vertical axis 26 and achieve steering of the wheel 35.
[0032] Example 2: This example further elaborates on Example 1 and includes a loading / unloading assembly 1. The loading / unloading assembly 1 includes a placement groove 11, which is installed at the upper center of the carrying plate 21. The cross-section of the placement groove 11 is adapted to the dimensions of the precast beam, enabling stable placement of the precast beam and preventing it from slipping during movement and turning. The inner surface of the placement groove 11 is provided with an anti-slip texture, further enhancing the stability of the precast beam during placement. Simultaneously, the edges of the placement groove 11 are rounded to avoid scratches or other injuries to operators during loading and unloading of the precast beam.
[0033] A set of fixing rings 12 are connected to each side of the placement groove 11. The fixing rings 12 are made of sturdy and durable metal. The precast beam is fixed by passing a rope through the fixing rings 12.
[0034] Example 3: This example further elaborates on Example 1 or 2. One of the mounting bases 41 is connected to a counterweight telescopic rod 48, and the telescopic end of the counterweight telescopic rod 48 is connected to the corresponding ring 43. The extension and retraction of the balancing hydraulic rod 42 causes a change in the center of gravity of the device.
[0035] The workflow of this embodiment is as follows: Hydraulic rod 42 drives a ring 43 to swing, a ring 43 drives a power block 45 to swing and move along a straight groove 47, a power block 45 drives a power rod 44 to swing, a power rod 44 drives another power block 45 to swing and move along a straight groove 47, another power block 45 drives another ring 43 to swing, another ring 43 drives a counterweight telescopic rod 48 to extend and retract and swing, and the counterweight telescopic rod 48 drives another mounting base 43 to rotate.
[0036] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
