Description

Technical Field

[0001] This utility model relates to the field of fixing fixtures, and in particular to a fixing fixture for prefabricated building components. Background Technology

[0002] Fixtures are devices used in mechanical manufacturing to hold workpieces in place, ensuring they maintain the correct position and condition during machining. They play a vital role in improving machining accuracy, increasing production efficiency, improving working conditions, and expanding the range of machine tool processes. They are also used in the field of prefabricated building components.

[0003] In the construction of prefabricated buildings, the precise fixing and positioning of prefabricated components (such as walls, beams, columns, and floor slabs) is a crucial step in ensuring building quality and construction safety. Traditional methods of fixing components mainly rely on welding, bolting, or simple mechanical clamps. Traditional clamps are usually customized for specific components and are difficult to adapt to prefabricated components of different sizes and shapes.

[0004] Therefore, it is necessary to provide a new type of prefabricated building component fixing fixture to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a prefabricated building component fixing clamp.

[0006] The present invention provides a prefabricated building component fixing fixture including a base plate, a first connecting plate, a second connecting plate, a driving component and a clamping component. The top ends of the first connecting plate and the second connecting plate are fixedly connected to the bottom end of the base plate. The clamping component is disposed between the first connecting plate and the second connecting plate. One side of the driving component is fixedly connected to one side of the second connecting plate. The output end of the driving component is fixedly connected to one end of the clamping component.

[0007] The clamping assembly includes two first connecting posts, forward and reverse lead screws, and two moving mechanisms. The two ends of the two first connecting posts are fixedly connected to the inner sides of the first connecting plate and the second connecting plate, respectively. The two ends of the forward and reverse lead screws are rotatably connected to the inner sides of the first connecting plate and the second connecting plate. The forward and reverse lead screws are located in the middle of the two first connecting posts. One end of the forward and reverse lead screws is fixedly connected to the output end of the drive assembly. The two first connecting posts are slidably connected to the two moving mechanisms. The forward and reverse lead screws are threadedly connected to the moving mechanisms.

[0008] Preferably, the moving mechanism includes a first moving plate, a first mounting plate, two clamps and a plurality of screws. The first moving plate is slidably connected to two first connecting columns. The first moving plate is threadedly connected to forward and reverse lead screws. The first moving plate is threadedly connected to the first mounting plate by a plurality of screws. One side of the first mounting plate is fixedly connected to one side of the two clamps.

[0009] Preferably, the two clamps are symmetrically inclined, and their opposite inclined surfaces are fixedly connected with anti-slip pads.

[0010] Preferably, the drive assembly includes a motor, a first mounting base, a second mounting base, a track, and a mounting box. One side of the second connecting plate is fixedly connected to one side of the motor, the output end of the motor is rotatably connected to the second connecting plate, the other side of the second connecting plate is fixedly connected to one side of the mounting box, the output end of the motor is fixedly connected to the first mounting base, one end of the forward and reverse lead screw is fixedly connected to the second mounting base, the track is sleeved on the outer surfaces of the first mounting base and the second mounting base, and the first mounting base, the second mounting base, and the track are located inside the mounting box.

[0011] Preferably, the first movable plate is provided with four first screw holes, and the first mounting plate is provided with a second screw hole at each of its four corners. The four first screw holes and the four second screw holes are used to connect the first movable plate and the first mounting plate with four screws.

[0012] Preferably, a lifting hook is fixedly connected to the top of the base plate.

[0013] Compared with related technologies, the prefabricated building component fixing clamp provided by this utility model has the following beneficial effects:

[0014] This invention provides a prefabricated building component fixing clamp. In practical implementation, when driven by a motor, the clamps on both sides can move synchronously in opposite directions or in opposite directions through a threaded connection design between forward and reverse lead screws and two moving mechanisms, ensuring symmetrical clamping of the building component. Compared with traditional single-sided driven clamps, this design avoids the component displacement problem caused by uneven force on one side, significantly improving clamping stability.

[0015] The first movable plate is connected to the first mounting plate by screw threads, and the clamp is fixed to the first mounting plate. This design allows for quick replacement of the appropriate clamp module according to different component shapes (such as square, round, and irregular shapes), making it far more versatile than traditional fixed clamps.

[0016] The anti-slip pads on the inclined surfaces of the clamps are made of high-strength rubber with micron-level raised textures on the surface, which can reduce the risk of surface damage to components.

[0017] The drive components' pulleys and tracks are all housed inside the mounting box, effectively preventing dust, mud, and other pollutants from the construction site from entering the transmission system.

[0018] The lifting hooks on the top of the base plate work directly with the tower crane equipment to achieve integrated operation of clamping aerial transfer and positioning, reducing the risk of manual handling at heights and improving installation efficiency. Attached Figure Description

[0027] In the specific implementation process, such as Figures 1-5 As shown, a prefabricated building component fixing fixture includes a base plate 1, a first connecting plate 2, a second connecting plate 3, a driving component, and a clamping component. The top ends of the first connecting plate 2 and the second connecting plate 3 are fixedly connected to the bottom end of the base plate 1. The clamping component is disposed between the first connecting plate 2 and the second connecting plate 3. One side of the driving component is fixedly connected to one side of the second connecting plate 3. The output end of the driving component is fixedly connected to one end of the clamping component.

[0028] The clamping assembly includes two first connecting posts 5, forward and reverse lead screws 6, and two moving mechanisms. The two ends of the two first connecting posts 5 are fixedly connected to the inner sides of the first connecting plate 2 and the second connecting plate 3, respectively. The two ends of the forward and reverse lead screws 6 are rotatably connected to the inner sides of the first connecting plate 2 and the second connecting plate 3. The forward and reverse lead screws 6 are located in the middle of the two first connecting posts 5. One end of the forward and reverse lead screws 6 is fixedly connected to the output end of the drive assembly. The two first connecting posts 5 are slidably connected to the two moving mechanisms. The forward and reverse lead screws 6 are threadedly connected to the moving mechanisms.

[0029] The moving mechanism includes a first moving plate 7, a first mounting plate 8, two clamps 9 and multiple screws 901. The first moving plate 7 is slidably connected to two first connecting columns 5. The first moving plate 7 is threadedly connected to forward and reverse lead screws 6. The first moving plate 7 is threadedly connected to the first mounting plate 8 by multiple screws 901. One side of the first mounting plate 8 is fixedly connected to one side of the two clamps 9.

[0030] The two clamps 9 are symmetrically inclined, and their opposite inclined surfaces are fixedly connected with anti-slip pads 10.

[0031] The drive assembly includes a motor 301, a first mounting base 302, a second mounting base 303, a track 304, and a mounting box 305. One side of the second connecting plate 3 is fixedly connected to one side of the motor 301. The output end of the motor 301 is rotatably connected to the second connecting plate 3. The other side of the second connecting plate 3 is fixedly connected to one side of the mounting box 305. The output end of the motor 301 is fixedly connected to the first mounting base 302. One end of the forward and reverse lead screw 6 is fixedly connected to the second mounting base 303. The track 304 is sleeved on the outer surfaces of the first mounting base 302 and the second mounting base 303. The first mounting base 302, the second mounting base 303, and the track 304 are located inside the mounting box 305.

[0032] The first movable plate 7 is provided with four first screw holes 701, and the first mounting plate 8 is provided with a second screw hole 801 at each of its four corners. The four first screw holes 701 and the four second screw holes 801 are used to connect the first movable plate 7 and the first mounting plate 8 with four screws 901. The top of the base plate 1 is fixedly connected with a lifting hook 4.

[0033] The working principle provided by this utility model is as follows: When using the device, after the motor 301 is started, the output shaft drives the first mounting base 302 to rotate. The motor adopts a servo motor that can rotate in both directions, which can accurately control the rotation angle and torque to meet the clamping force requirements of different components. The first mounting base 302 transmits power to the second mounting base 303 through the track 304. The second mounting base 303 is fixedly connected to the forward and reverse lead screw 6, thereby driving the lead screw to rotate. The two sections of the forward and reverse lead screw 6 have opposite screw directions. When the lead screw rotates, the two first moving plates 7 that are threaded to it move synchronously towards or away from each other along the first connecting column 5. The first connecting column 5 plays a guiding role. The first moving plate 7 is fixedly connected to the first mounting plate 8 through screw 901. The clamp 9 moves synchronously with the first mounting plate. The symmetrical inclined surfaces of the two clamps 9 form a wedge-shaped clamping space when they move towards each other, accommodating components of different sizes. The anti-slip pads 10 fixed to the inclined surfaces of the clamps 9 undergo elastic deformation when in contact with the component surface, absorbing vibration energy. The four first screw holes 701 of the first moving plate 7 are connected to the second screw holes 801 of the first mounting plate 8 by high-strength screws 901, ensuring connection rigidity. During disassembly, a pneumatic wrench can be used to replace the module. The lifting hook 4 directly cooperates with the tower crane equipment to achieve integrated operation of clamp aerial transfer and positioning, reducing the risk of manual handling at heights and improving installation efficiency.

[0034] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
