Description

Technical Field

[0001] The invention relates to the technical field of installation and construction of special-shaped components, and in particular to a lightweight special-shaped component construction device. Background Art

[0002] In the installation and construction of special-shaped components such as steel structure dampers, traditional processes often rely on manual hoists for lifting and temporary fixation. However, when the manual hoist is manually operated, the components are prone to rotation and displacement due to uneven force, resulting in deviations in the installation position, making it difficult to meet high-precision construction requirements. Subsequent adjustments will require a lot of time, seriously affecting the construction progress.

[0003] Another common method is to erect a full-span support frame, which provides support and positioning benchmarks for components by building dense steel pipe supports. However, this method requires a large amount of steel pipe materials, and the erection process requires a lot of manpower, which not only increases construction costs but also prolongs the preliminary preparation time. At the same time, the dismantling of the full-span support frame is also cumbersome, further slowing down the overall construction pace.

[0004] In addition, both the hand chain hoist and the full-span support frame have poor applicability in narrow spaces (such as inside floors). The operating space of the hand chain hoist is limited and it is easy to interfere with the surrounding structures. The full-span support frame may not be erected according to the designed dimensions due to the small space, resulting in insufficient support stability, which not only affects construction safety, but also makes it difficult to ensure the installation accuracy of special-shaped components, and cannot meet the needs of modern construction for efficient, precise and flexible operations. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a lightweight special-shaped component construction device to solve the technical problems raised in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a lightweight special-shaped component construction device, comprising a moving mechanism, a lifting mechanism and a supporting mechanism;

[0010] The bottom of the clip is fixed to the top of the jack by full welding. The bolt hole diameter of the clip matches the bolt hole of the ear plate of the special-shaped component and is suitable for M12-M20 specification bolts.

[0012] The jack is a hydraulic jack with a maximum load capacity of ≥5t, a lifting height adjustment range of 300-1500mm, and a height locking function;

[0013] The support mechanism includes a support column, a rotating frame and a connecting plate. The bottom of the support column is detachably connected to the card slot of the base. One end of the rotating frame is hinged to the top of the support column and the other end is fixed to the connecting plate. The connecting plate is provided with a bolt connection hole.

[0014] The hinge between the rotating frame and the support column is equipped with a damping shaft, which can achieve angle adjustment within the range of 0-90° and maintain a stable state after adjustment.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0025] The following describes an embodiment of the present invention based on its overall structure.

[0026] Example 1

[0027] like Figure 1-6 As shown, the lightweight special-shaped component construction device of this embodiment realizes the precise lifting and stable support of special-shaped components such as steel structure dampers through modular combination design. The specific structure is as follows:

[0028] The moving mechanism 1 comprises:

[0029] Base 101: Made of welded aluminum alloy profiles, it is square in shape. A slot 102 is provided at the center of the top. An anti-slip rubber pad is provided inside the slot 102, and a guide strip along the depth direction is provided on the inner wall. It is used to connect with the lifting mechanism 2 or the supporting mechanism 3, with a connection gap of ≤1mm.

[0030] Universal wheels 103: These are silent universal wheels with braking functions. There are four sets of them, evenly distributed at the bottom of the base 101, to facilitate the movement and fixation of the entire device.

[0031] The lifting mechanism 2 includes:

[0032] Jack 201: This is a hydraulic jack. Its bottom can be inserted into the slot 102 of the base 101 to form a detachable connection. The bottom is provided with a guide groove adapted to the guide strip of the slot 102. The guide accuracy is ≤ 0.3mm. The jack 201 has a height locking function to adjust the lifting height of the special-shaped component.

[0033] Buckle 202: The bottom is fixed to the top of the jack 201 by full welding. Bolt holes are reserved on the buckle 202. The bolt hole diameter matches the bolt hole of the ear plate of the special-shaped component 4 and is suitable for M12-M20 specification bolts for connection and fixation with the special-shaped component 4;

[0034] The supporting mechanism 3 includes:

[0035] Support column 301: Made of high-strength alloy steel pipe, the bottom can be inserted into the slot 102 of the base 101 to form a detachable connection. The bottom is provided with a guide groove adapted to the guide strip of the slot 102. The height of the support column 301 can be adjusted by a telescopic joint, and a locking bolt is provided at the telescopic joint to fix the adjusted height;

[0036] Rotating frame 302: One end is hinged to the top of the support column 301. A damping shaft is provided at the hinge, which can be adjusted in the range of 0-90 degrees and can maintain a stable state after adjustment. The other end is fixedly connected to the connecting plate 303.

[0037] Connecting plate 303: Cut and formed from Q235 steel plate, with bolt connection holes 304 arranged on it. The bolt connection holes 304 are arranged according to the connection node spacing at the bottom of the special-shaped component 4, with an aperture error of ≤0.5mm, and are used for connection and fixation with the bottom of the special-shaped component 4;

[0038] Device assembly and preparation

[0039] According to the installation requirements of the special-shaped component 4, two groups of mobile mechanisms 1 are selected. The lifting mechanism 2 is installed in the slot 102 of one group of mobile mechanisms 1. The bottom of the jack 201 is inserted into the slot 102. The guide bar and the guide groove cooperate to achieve precise positioning. The support mechanism 3 is installed in the slot 102 of the other group of mobile mechanisms 1. The support column 301 is also installed through the guide structure.

[0040] According to the size of the special-shaped component 4, adjust the telescopic joint of the support column 301 to the appropriate height and fix it with locking bolts. Adjust the angle of the connecting plate 303 through the rotating frame 302 to make it fit the bottom connection node of the special-shaped component 4;

[0041] Special-shaped component connection

[0042] Fix the bottom of the special-shaped member 4 to the connecting plate 303 of the supporting mechanism 3 through bolts and bolt connection holes 304 to ensure a firm connection;

[0043] Align the ear plate at one end of the special-shaped component 4 with the buckle 202 of the lifting mechanism 2, and pass M12-M20 bolts through the bolt holes of the buckle 202 and the bolt holes of the ear plate to complete the fixed connection between the two;

[0044] Movement and positioning

[0045] Push the two sets of moving mechanisms 1 to move the entire device together with the special-shaped component 4 to the position directly below the location to be installed, and step on the brake device of the universal wheel 103 to fix the position of the device;

[0046] Lifting and fixing

[0047] Operate the jack 201 of the lifting mechanism 2 to slowly lift one end of the special-shaped component 4. During the lifting process, the rotating frame 302 of the supporting mechanism 3 cooperates with the connecting plate 303 to keep the special-shaped component 4 stable and prevent it from deflecting or rotating.

[0048] When the special-shaped component 4 reaches the designed installation height, the height of the jack 201 is locked, and the position of the special-shaped component 4 is fine-tuned to fully meet the installation requirements, and then the final installation and fixing operation of the special-shaped component 4 is carried out;

[0049] Device disassembly

[0050] After the special-shaped component 4 is fixed, loosen the connecting bolts of the buckle 202 and the ear plate, as well as the fixing bolts of the special-shaped component 4 and the connecting plate 303, and remove the lifting mechanism 2 and the supporting mechanism 3 from the slot 102 of the base 101 to complete the separation of the device and the component;

[0051] The device adopts a modular design. The moving mechanism 1 can be flexibly combined with the lifting mechanism 2 and the supporting mechanism 3 to adapt to special-shaped components 4 of different sizes and weights, and has strong versatility.

[0052] The universal wheel 103 is easy to install in a small space, such as moving inside a floor, solving the problem of poor applicability of traditional construction methods in small spaces, and the braking function ensures stability during construction;

[0053] The jack 201 can accurately adjust the lifting height, and cooperate with the angle adjustment function of the support mechanism 3 to effectively prevent the special-shaped component 4 from rotating or deflecting during the lifting process, thereby improving the installation accuracy;

[0054] The base 101 is made of aluminum alloy profiles, which is light in weight and reusable, reducing material consumption. At the same time, it eliminates the tedious steps of erecting and dismantling the full-floor support frame, shortens the construction period, and reduces construction costs.

[0055] This embodiment is suitable for the installation and construction of special-shaped components such as steel structure dampers, and is particularly suitable for high-precision installation operations in narrow spaces.

[0056] The working principle of the present invention is as follows: before construction, an adapted connecting plate 303 is made according to the size of the special-shaped component 4 (such as a damper) to be installed, and the bottom of one end of the special-shaped component 4 is temporarily fixed to the connecting plate 303 by means of bolts and bolt connection holes 304. Then, it is placed on the mobile mechanism 1 with universal wheels 103, and the jack 201 of the lifting mechanism 2 is inserted into the slot 102 of another set of mobile mechanisms 1 and fixed. The buckle 202 is connected and fixed to the ear plate on the other end of the special-shaped component 4 with bolts through the bolt holes of the buckle 202 on the upper part of the lifting mechanism 2;

[0057] Under the action of the two sets of moving mechanisms 1, the entire device is moved to the position directly below the location to be installed. Then, the universal wheels 103 are locked to fix the positions of the two sets of moving mechanisms 1. The switch of the jack 201 is operated to slowly lift one end of the special-shaped component 4 to the designed installation height. During this process, the rotatable connecting plate 303 of the supporting mechanism 3 is connected to the bottom of the special-shaped component 4 to ensure that the special-shaped component 4 does not deviate or rotate during the lifting process and remains stable.

[0058] When the special-shaped component 4 reaches the specified height, the switch of the jack 201 is turned off, and the position of the special-shaped component 4 is fine-tuned to fully meet the installation requirements. Then, the final installation and fixing operation of the special-shaped component 4 is carried out. After the fixing is completed, the connecting bolts of the buckle 202 and the ear plate of the special-shaped component 4 and the fixing bolts of the special-shaped component 4 and the connecting plate 303 are loosened to separate the device from the component, completing the entire installation process;

[0059] Compared with traditional construction methods such as hand hoists and full-floor support frames, this device ensures the stability of the special-shaped components 4 during installation, avoids offset, and significantly improves the installation accuracy. At the same time, it greatly shortens the time for positioning and adjusting the special-shaped components 4, simplifies the construction process, and reduces the construction difficulty. It is especially suitable for the installation and construction of special-shaped components 4 in narrow spaces such as floors, and the mobile mechanism 1 as a whole is reusable and universal, with good economy and practicality.

The specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.
