Description

Technical Field

[0001] This utility model relates to the field of construction machinery technology, and in particular to a construction tilting machine. Background Technology

[0002] In various construction sites such as building, chemical, and machinery installation, it is often necessary to install large equipment or prefabricated components. Due to their large size and weight, these large equipment or prefabricated components are usually placed on pallets in a sideways position during long-distance freight to improve transportation stability and save space. When these equipment or prefabricated components arrive at the construction site, they cannot be installed directly. They must first be flipped from their sideways position to the required installation posture using appropriate equipment, and then lifted and precisely installed using hoisting equipment. In this process, construction tilting machines become one of the key pieces of equipment to ensure the smooth progress of the operation.

[0003] Existing technologies already include equipment for flipping construction components, such as the patented "A Building Wall Flipping Robot and Transfer System" (CN110616903B). This patent utilizes a transport trolley, lifting mechanism, flipping mechanism, and multi-stage telescopic mechanism to achieve the flipping and transfer of building walls, effectively solving the problems of difficulty in flipping hollow building walls and low efficiency of manual flipping. However, this patented technology mainly focuses on the flipping and transfer design of building walls. Its structural layout and function emphasize the clamping and fixing of the wall and the flipping drive, but it does not provide an effective technical solution for the lifting guidance and bottom protection of components placed on their side after transportation.

[0004] In actual construction operations, there are still significant shortcomings when using existing tilting equipment to handle large, sideways-lying equipment or precast components transported by freight. When lifting the tilted equipment or precast components, the lack of a dedicated guiding structure makes it easy for the components to sway and shift during the lifting process, making it difficult to accurately align them with the installation position. At the same time, during the transition from side-lying placement to tilting and lifting, the bottom of the components in contact with the ground lacks effective protection measures, making them extremely susceptible to direct collisions with the ground. This can not only cause surface damage and structural deformation of the equipment or precast components, but also damage the ground of the construction site. More seriously, the displacement or detachment of components caused by collisions may pose a serious threat to the personal safety of nearby construction workers. Utility Model Content

[0005] The purpose of this utility model is to provide a construction tilting machine that can solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a construction tilting machine, comprising a fork plate, a pallet, a base, and a rotating shaft. The fork plate adopts a "mountain"-shaped structure design, which allows for a stable fit with the bottom of the pallet beneath the side-lying equipment or precast component. It can easily extend into the bottom of the pallet to provide reliable support, preventing direct contact between the bottom of the equipment or precast component and the ground, thus avoiding impact damage. Simultaneously, the "mountain"-shaped structure enhances the stability of the contact between the fork plate and the pallet, preventing lateral displacement during lifting and tilting. The cross-section of the fork plate is wedge-shaped. This wedge structure effectively reduces the resistance when the fork plate extends into the bottom of the pallet, making the fork plate insertion operation more convenient and efficient, further improving work efficiency. The pallet is integrally formed and connected to the side end face of the fork plate, forming a right angle with it. This integral right-angle connection structure not only enhances the overall structural strength but also forms an enclosed support space with the fork plate. When equipment or prefabricated components are placed between the fork plate and the pallet, it provides reliable limiting constraints, offering a stable guiding foundation for subsequent lifting and tilting, and preventing swaying and deviation due to lack of guidance during lifting. The base is located below the fork plate and the pallet, with the fork plate and pallet situated between two sets of bases. The symmetrical layout of the two sets of bases provides a stable support foundation for the overall structure, ensuring the overall stability of the equipment during tilting. The pivot is installed at the connection between the fork plate and the pallet, with both ends rotatably mounted between the two sets of bases. This hinged installation method allows the fork plate and the pallet to rotate flexibly around the pivot, providing stable rotational support for the tilting action of the equipment or prefabricated components, ensuring a smooth and controllable tilting process.

[0007] Preferably, a support member connects the two sets of bases. The support member further enhances the connection strength between the two sets of bases and improves the stability of the overall structure. A telescopic cylinder is installed between the top of the support member and the support plate. The bottom and free ends of the telescopic cylinder are hinged to the support plate and the support member, respectively. The hinged design of the telescopic cylinder provides precise driving force for the flipping action and plays an auxiliary guiding role during the flipping process. It effectively controls the flipping speed and angle, avoids component shaking caused by excessive speed or angle deviation during the flipping process, greatly improves the accuracy of lifting and alignment, and facilitates subsequent installation operations.

[0008] Preferably, two sets of mounting plates parallel to the support member are connected between the two sets of bases for supporting the pallet and fork plate, with the support member located between the two sets of mounting plates. The mounting plates provide stable support for the fork plate and pallet during idle periods or at the beginning and end of a flipping operation, preventing damage due to uneven stress at the connection point caused by prolonged suspension. Simultaneously, the two sets of mounting plates are symmetrically distributed on both sides of the support member, further optimizing the overall stress structure and enhancing the load-bearing capacity of the equipment. Multiple sets of rubber seats are installed on the top of the mounting plates. These rubber seats have excellent elastic cushioning performance, effectively absorbing the impact force when the fork plate and pallet are placed, reducing hard collision damage between structures, extending the service life of the equipment, and also providing auxiliary cushioning and stabilization during flipping. Brake wheels are installed on the adjacent sidewalls of both sets of bases near the bottom corners. The design of the brake wheels allows the equipment to move flexibly according to the needs of the construction site, improving the equipment's operational adaptability, while the braking function stabilizes the equipment during operation, preventing displacement during flipping and further ensuring operational safety.

[0009] Compared with the prior art, the beneficial effects of this utility model are: This application effectively solves the problem of lack of guiding assistance during lifting in the prior art by combining a "mountain"-shaped fork plate and a pallet. During operation, the "mountain"-shaped fork plate can stably extend into the bottom of the pallet of the side-lying equipment or prefabricated component. The right-angled pallet, which is integrally formed on the end face of the fork plate, can form an enclosing support structure with the fork plate, so that the equipment or prefabricated component can be attached between the fork plate and the pallet before lifting, forming a reliable limiting constraint. At the same time, the connection between the fork plate and the pallet is hinged in the support base and, with the assistance of the telescopic cylinder, can provide a stable guiding effect for the equipment or prefabricated component during the tilting and lifting process. This effectively avoids the swaying and deviation problem caused by lack of guidance during lifting, greatly improves the accuracy of lifting alignment, and provides a guarantee for the smooth progress of subsequent installation operations. To address the shortcomings of existing technologies where side-lying equipment or precast components lack bottom protection and are prone to collisions with the ground, this application utilizes a support method where forks extend into the bottom of a pallet. This ensures stable contact between the bottom of the equipment or precast component and the pallet, preventing direct contact with the ground. The enclosing structure formed by the forks and pallet effectively protects the bottom and sides of the equipment or precast component, maintaining isolation between the bottom and the ground throughout the entire process of flipping and lifting, fundamentally solving the problem of bottom collisions. This not only effectively prevents surface damage and structural deformation of the equipment or precast component caused by collisions but also avoids damage to the construction site ground, reducing equipment maintenance and ground repair costs.

[0012] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0013] Please see Figure 1-3 This utility model provides a technical solution: a construction tilting machine, including a fork plate 1, a pallet 2, a base 3 and a rotating shaft 9. The fork plate 1 has a "mountain" shaped structure for extending into the bottom of the pallet. This "mountain" shaped structure can stably adapt to the pallet under the side-lying equipment or precast component, smoothly extending into the bottom of the pallet to form reliable support and prevent the bottom of the equipment or precast component from directly contacting the ground and causing collisions. The cross-section of the fork plate 1 is wedge-shaped. The wedge-shaped cross-section design reduces the insertion resistance of the fork plate 1 into the bottom of the pallet, making the operation more labor-saving. The pallet 2 is integrally formed and connected to the side end face of the fork plate 1, with an angle of 90° between them. This integral right-angle connection enhances the overall structural integrity and forms a limiting space with the fork plate 1, which serves to limit the movement of the equipment or prefabricated components. The base 3 is located below the fork plate 1 and the pallet 2, with the fork plate 1 and the pallet 2 situated between two sets of bases 3. The two sets of bases 3 are symmetrically arranged, providing a stable support for the overall structure. The rotating shaft 9 is installed at the connection between the fork plate 1 and the pallet 2. Both ends of the rotating shaft 9 are rotatably installed between the two sets of bases 3. The rotatable installation of the rotating shaft 9 allows the fork plate 1 and the pallet 2 to rotate flexibly around it, ensuring smooth flipping.

[0014] A support member 5 connects the two sets of bases 3, enhancing the connection rigidity between them. A telescopic cylinder 6 is installed between the top of the support member 5 and the pallet 2. The bottom and free end of the telescopic cylinder 6 are hinged to the pallet 2 and the support member 5, respectively. This hinged connection provides controllable driving force for the flipping action and also serves as an auxiliary guide to prevent swaying during flipping. Two sets of support plates 4, parallel to the support member 5, are connected between the two sets of bases 3 to support the pallet 2 and the fork plate 1. The support 5 is located between the two sets of ramps 4. The two sets of ramps 4 can support the fork plate 1 and pallet 2 when the equipment is idle or at the beginning and end of the flip, preventing them from being suspended for a long time and causing uneven force at the connection. Multiple sets of rubber seats 7 are installed on the top of the ramps 4. The rubber seats 7 can buffer the impact force when the fork plate 1 and pallet 2 are placed, reducing hard collisions. Brake wheels 8 are installed on the adjacent side walls of the two sets of bases 3 near the bottom corners. The brake wheels 8 facilitate the overall movement of the equipment, improve the flexibility of operation, and the braking function can fix the equipment during operation to prevent displacement.

[0015] Working principle: Before operation, push the equipment to the pallet next to the side-lying equipment or prefabricated component using the brake wheel 8, and lock the brake wheel 8 to fix the equipment position; align the fork plate 1 with the gap at the bottom of the pallet and insert it so that the pallet is completely overlapped on the fork plate 1, at which point the pallet 2 is attached to the side of the equipment or prefabricated component; activate the telescopic cylinder 6, the free end of the telescopic cylinder 6 extends and pushes the pallet 2, causing the fork plate 1 and the pallet, along with the equipment or prefabricated component, to rotate around the rotating shaft 9, realizing the flipping action; after flipping to the target posture, the telescopic cylinder 6 stops and maintains the extension amount, cooperating with the lifting equipment to complete the lifting operation of the equipment or prefabricated component; after the lifting is completed, the free end of the telescopic cylinder 6 retracts, causing the fork plate 1 and pallet 2 to return to the rubber seat 7 of the pallet 4, and unlock the brake wheel 8 to move the equipment to the next working position or storage point.

[0016] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
