Description

Technical Field

[0001] This invention relates to the field of building engineering technology, specifically to a molding device for building engineering materials. Background Technology

[0002] Vibration compaction of building materials is a process that uses the excitation force generated by vibrating equipment to cause relative displacement of plastic building material particles such as concrete and mortar, expelling internal air, reducing porosity, and achieving dense compaction. It is widely used in the pouring and construction of concrete components, walls, roads, and other projects. The vibrating equipment uses high-frequency vibration to generate inertial force in the particles inside the material, overcoming the friction and cohesion between particles, and putting them in a suspended fluidized state. Under the action of gravity and vibration, the particles rearrange themselves, filling the gaps, while expelling the trapped air, ultimately improving the density, strength, and durability of the material.

[0003] For example, the array-type vibratory compaction device with publication number CN108867264A solves the problems of poor reliability and short service life of vibratory rods by providing unified power to the vibratory pipes from the outside, ensuring the normal progress of construction and improving construction efficiency. However, when multiple vibratory pipes are arranged in a row, they will drive the concrete to vibrate synchronously. This vibration will overlap with the vibration of the vibratory pipes, which will cause some of the vibration caused by the vibratory pipes to be eliminated, ultimately reducing the vibration efficiency of the vibratory pipes. In addition, the vibration frequencies emitted by multiple vibratory pipes are different, which will cause the connection between the support and the vibratory pipe to be constantly affected by shear force, resulting in a significant reduction in the service life of the vibratory pipes. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a molding device for building engineering materials.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a forming device for building engineering materials, including a support plate, a vibration component is provided on the surface of the support plate, a fixing component is provided on the upper surface of the support plate, and a driving component is provided on the lower surface of the support plate. The vibrating assembly includes four strip-shaped openings, which are equidistantly spaced around the center of the support plate. Multiple clamping holes are equidistantly spaced on the inner wall of each strip-shaped opening. A vibrating rod is inserted into each clamping hole. A retaining ring is fixedly sleeved on the upper end of each vibrating rod. A clamping groove is formed on the lower surface of the vibrating rod. Multiple retaining grooves are formed on the inner wall of each clamping groove. A steel cable is retained inside each retaining groove. A connecting rod is embedded on the surface of the steel cable. A connecting plate is fixedly connected to the upper end of the connecting rod. An arc surface is formed on the side of the connecting plate closest to the center of the support plate.

[0006] Specifically, the two ends of the steel cable are connected in a U-shape, and the steel cable is clamped into clamping grooves at the same horizontal level inside multiple vibrating rods.

[0007] Specifically, the lower end of the connecting plate is provided with multiple connecting rods, and multiple steel cables are embedded inside the connecting rods.

[0008] Specifically, the fixing component includes a stud, which is fixedly connected to the center of the lower surface of the support plate. A support ring is fixedly sleeved on the lower end of the stud. A collar is movably sleeved on the surface of the stud. A threaded cylinder is threadedly connected to the surface of the stud. Two push rods are symmetrically fixedly connected to the outer wall of the threaded cylinder. Four fixing plates are equidistantly fixedly connected to the outer wall of the collar. A connecting strip is fixedly connected to the side wall of the other end of the fixing plate. An insert rod is fixedly connected to the lower surface of the fixing plate. Four slots are opened on the upper surface of the support plate, and the insert rod is inserted into the corresponding slot.

[0009] Specifically, the fixing plate corresponds to the strip opening and is pressed against the upper surface of the snap ring.

[0010] Specifically, the drive assembly includes four fixing blocks, which are fixedly connected to the lower surface of the support plate. A mounting plate is fixedly connected to the lower end of the fixing blocks, and a motor is fixedly connected to the lower surface of the mounting plate. A turntable is fixedly connected to the output end of the motor, and eight semi-circular push blocks are fixedly connected at equal intervals on the outer circular sidewall of the turntable.

[0011] Specifically, the semicircular push block corresponds to four arc surfaces, and the four arc surfaces are engaged in the gaps between the eight semicircular push blocks.

[0012] The beneficial effects of this invention are: (1) The forming device for building materials described in this invention effectively avoids the problem of mutual cancellation of vibration in traditional array-type vibratory devices through the coordinated design of the vibratory component and the driving component. The vibratory rods in the four strip-shaped openings are connected as a whole by the U-shaped steel cable. The semi-circular push block on the motor-driven turntable alternately squeezes the arc surface of the connecting plate, so that multiple vibratory rods generate high-frequency reciprocating vibration synchronously, reducing the loss of vibration energy and significantly improving the compaction and efficiency. At the same time, the flexible connection of the steel cable can buffer the vibration difference between the vibratory rods, avoid damage caused by shear force concentration at the connection between the support and the vibratory rod, and extend the service life of the device.

[0013] (2) The forming device for building materials described in this invention has a compact and convenient fixed component structure. Through the threaded engagement of the threaded cylinder and the stud, the collar can be pushed to move the fixed plate along the surface of the support plate, so that the fixed plate can accurately squeeze the snap ring at the upper end of the vibrating rod, thereby achieving a stable limit of the vibrating rod in the clamping hole. The insertion engagement of the insert rod and the slot further improves the support stability of the fixed plate, avoids the vibrating rod from shifting or shaking during the vibration process, and ensures the accuracy of the vibration operation. In addition, by changing the snap groove of different heights and cooperating with the steel cable, the insertion depth of the vibrating rod can be flexibly adjusted to meet the vibration requirements of building materials of different thicknesses, thereby enhancing the versatility of the device.

[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1 to 7 The present invention provides the following technical solutions: Example 1: A molding device for building materials includes a support plate 1, a vibrating component 2 disposed on the surface of the support plate 1, a fixing component 3 disposed on the upper surface of the support plate 1, and a driving component 4 disposed on the lower surface of the support plate 1. The vibratory assembly 2 includes four strip-shaped openings 21, which are equidistantly spaced around the center of the support plate 1. Multiple clamping holes 22 are equidistantly spaced on the inner wall of the strip-shaped openings 21. A vibratory rod 23 is inserted into the clamping hole 22. A snap ring 24 is fixedly sleeved on the upper end of the vibratory rod 23. A clamping groove 25 is formed on the lower end surface of the vibratory rod 23. Multiple snap-fit ​​grooves 26 are formed on the inner wall of the clamping groove 25. A steel cable 27 is snapped into the snap-fit ​​groove 26. A connecting rod 28 is embedded on the surface of the steel cable 27. A connecting plate 29 is fixedly connected to the upper end of the connecting rod 28. An arc surface 210 is formed on the side of the connecting plate 29 near the center of the support plate 1.

[0019] The two ends of the steel cable 27 are connected in a U-shape and the steel cable 27 is clamped onto the clamping groove 26 at the same horizontal level inside multiple vibrating rods 23.

[0020] The lower end of the connecting plate 29 is provided with multiple connecting rods 28, and multiple steel cables 27 are embedded inside the connecting rods 28.

[0021] During use, select the appropriate number of clamping holes 22 on the inner wall of the strip opening 21 on the support plate 1 according to the pouring area of ​​the material to be vibrated. Insert the vibrating rods 23 one by one into the clamping holes 22, ensuring that the lower end of the vibrating rod 23 extends to meet the material vibration depth requirements. This can be roughly adjusted by adjusting the position of the insertion clamping holes 22. Then, according to the vibration depth, precisely select the locking grooves 26 at the same horizontal height in the clamping grooves 25 at the lower end of each vibrating rod 23. Connect the U-shaped steel cable 27 to the locking grooves 26 of all vibrating rods 23. The flexible connection of the steel cable 27 enables multiple vibrating rods 23 to form a synchronous linkage structure. Check the connection stability between the connecting plate 29 and the steel cable 27, ensuring that the connecting rod 28 is firmly embedded in the surface of the steel cable 27, and that the arc surface 210 of the connecting plate 29 near the center of the support plate 1 remains flat. Observe its stability by manually pushing any vibrating rod 23. He checked whether the vibrating rods 23 were slightly displaced synchronously to verify the linkage effect of the steel cable 27, avoiding uneven vibration transmission due to loose connection. When the drive component 4 provides power, the connecting plate 29 drives the steel cable 27 to perform high-frequency reciprocating motion. The steel cable 27 drives all the vibrating rods 23 to vibrate synchronously along the axis of the clamping hole 22 through the snap-fit ​​groove 26. The vibration of the vibrating rods 23 is transmitted to the interior of materials such as concrete and mortar, so that the material particles overcome friction and cohesion and are in a suspended fluidized state. The particles rearrange to fill the gaps and at the same time expel the trapped air, so as to achieve the dense forming of the material. The flexible connection of the steel cable 27 can buffer the vibration difference between the vibrating rods 23, avoid damage caused by shear force concentration at the connection between the clamping hole 22 and the vibrating rod 23, and ensure the fixation of the vibrating rods 23 even when the clamping hole 22 is affected and damaged, thus extending the service life of the device.

[0022] Example 2: The technical solution of this example, which differs from that of Example 1, includes: the fixing component 3 includes a stud 31, which is fixedly connected to the center of the lower surface of the support plate 1. A support ring 32 is fixedly sleeved on the lower end of the stud 31. A collar 33 is movably sleeved on the surface of the stud 31. A threaded cylinder 34 is threadedly connected to the surface of the stud 31. Two push rods 35 are symmetrically fixedly connected to the outer wall of the threaded cylinder 34. Four fixing plates 36 are fixedly fixedly connected at equal intervals on the outer wall of the collar 33. A connecting strip 37 is fixedly connected to the side wall of the other end of the fixing plate 36. An insert rod 38 is fixedly connected to the lower surface of the fixing plate 36. Four slots 39 are opened on the upper surface of the support plate 1, and the insert rod 38 is inserted into the corresponding slot 39.

[0023] The fixing plate 36 corresponds to the slot 21 and is pressed against the upper surface of the snap ring 24.

[0024] In use, the collar 33 is movably fitted onto the stud 31 at the center of the lower surface of the support plate 1, so that the four fixing plates 36 on the outer wall of the collar 33 correspond one-to-one with the four slots 21 on the support plate 1. The insertion rod 38 on the lower surface of the fixing plate 36 is aligned with the slot 39 on the upper surface of the support plate 1 and inserted. The engagement of the insertion rod 38 and the slot 39 achieves the initial positioning of the fixing plate 36 and prevents lateral displacement of the fixing plate 36. The two push rods 35 on the outer wall of the threaded cylinder 34 are rotated. Utilizing the threaded transmission relationship between the threaded cylinder 34 and the stud 31, the collar 33 is pushed to move upward along the stud 31. The collar 33 drives the fixing plate 36 to rise synchronously until... The lower surface of the fixing plate 36 is tightly pressed against the retaining ring 24 at the upper end of the vibrating rod 23. The bearing effect of the retaining ring 24 limits the vibrating rod 23 within the clamping hole 22, ensuring that the vibrating rod 23 does not move longitudinally during the vibration process. Before operation, the fixing strength is verified by manually moving the vibrating rod 23 to ensure that the vibrating rod 23 can sway. If the position of the vibrating rod 23 needs to be adjusted, the push rod 35 is rotated in the opposite direction to move the threaded cylinder 34 down, and the fixing plate 36 is disengaged from the retaining ring 24. After adjusting the vibrating rod 23, it is re-compacted and fixed. During operation, if abnormal vibration is found, the machine should be stopped to check whether the fixing plate 36 is offset and whether the insert rod 38 is disengaged from the slot 39. Tighten and adjust in time.

[0025] Example 3: The technical solution of this example that differs from that of Example 2 includes: the drive component 4 includes four fixing blocks 41, the fixing blocks 41 are fixedly connected to the lower surface of the support plate 1, the lower end of the fixing blocks 41 is fixedly connected to the mounting plate 42, the lower surface of the mounting plate 42 is fixedly connected to the motor 43, the output end of the motor 43 is fixedly connected to the turntable 44, and eight semi-circular push blocks 45 are fixedly connected at equal intervals on the outer circular side wall of the turntable 44.

[0026] The semicircular push block 45 corresponds to the four arc surfaces 210, and the four arc surfaces 210 are engaged in the gaps between the eight semicircular push blocks 45.

[0027] In use, the mounting plate 42 is horizontally fixed to the lower surface of the support plate 1 using the fixing block 41, ensuring that the mounting plate 42 and the support plate 1 remain parallel. The motor 43 is fixed to the lower surface of the mounting plate 42. The power supply of the motor 43 is connected and a no-load test run is performed. Check whether the turntable 44 at the output end of the motor 43 rotates horizontally and whether the eight semi-circular push blocks 45 on the outer circular side wall of the turntable 44 are secure, to avoid power transmission offset due to installation tilt. Adjust the installation position of the motor 43 so that the semi-circular push blocks 45 on the turntable 44 are precisely aligned with the arc surface 210 of the connecting plate 29, ensuring that the four connecting plates are aligned. The arc surface 210 of the connecting plate 29 fits precisely into the gap between the eight semi-circular push blocks 45. According to the material vibration requirements, the speed of the motor 43 is adjusted by the controller of the motor 43, thereby controlling the rotation frequency of the turntable 44. The motor 43 drives the turntable 44 to rotate at a uniform speed. The semi-circular push blocks 45 alternately press the arc surface 210 of the connecting plate 29, pushing the connecting plate 29 to move away from the center. When the semi-circular push blocks 45 disengage from the arc surface 210, the elastic restoring force of the steel cable 27 drives the connecting plate 29 to reset, forming a high-frequency reciprocating motion, providing continuous and stable vibration power for the vibration assembly 2.
