Description

Technical Field

[0001] The invention relates to the technical field of vibration platforms, in particular to a prefabricated concrete component vibration platform. Background Art

[0002] The precast concrete vibration platform is a special equipment used in the production process of precast concrete components. It mainly uses mechanical vibration to make the concrete mixture poured into the mold uniform and dense, expel internal air, and eliminate bubbles, thereby improving the strength, durability and surface quality of the precast parts.

[0003] After searching, according to the Chinese patent with the announcement number CN206883853U, a concrete precast part vibration device is disclosed, including a vibration platform, a first groove is provided on the vibration platform, a mounting platform and a baffle are slidably installed in the first groove, the baffle is located on one side of the mounting platform, two symmetrically arranged second grooves are provided on the inner walls on both sides of the first groove, and a clamping column is slidably installed in the two second grooves, a clamping groove is provided on both sides of the baffle, the clamping groove is adapted to the clamping column, and a through hole is provided on the inner wall on one side of the second groove. The device has a simple structure and is easy to operate. The mounting platform and the baffle are slid into the first groove in turn, the spring force pushes the push rod and the clamping column, the clamping column is clamped into the clamping groove, the baffle, the mounting platform and the vibration motor are fixed, the handle is pulled, the clamping column is separated from the clamping groove, the baffle is released, the baffle and the mounting platform can be taken out from the first groove, the vibration motor can be quickly installed and taken out, and the vibration motor can be easily repaired and maintained; however, when the scheme is actually used, there are still the following shortcomings: The conventional operation mode of the above-mentioned vibration device is to place the prefabricated mold directly on the platform surface, then fill the mold with concrete raw materials and start the vibration program. However, in actual production, since the filling amount of concrete raw materials is difficult to control accurately, when the operator accidentally fills in too much concrete, the high-frequency vibration will increase the fluidity of the concrete, causing the part that exceeds the mold capacity to overflow from the edge of the mold and fall onto the surface of the vibration platform. If the overflowed concrete is not cleaned up in time, it will solidify rapidly in a short period of time and adhere tightly to the platform surface, seriously damaging the flatness and smoothness of the platform surface, which will directly affect the fit between the mold and the platform, causing the mold to shake violently, shift or even bounce due to uneven force during the vibration process.

[0004] Based on this, the invention discloses a precast concrete component vibration platform. Summary of the invention

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] The present invention provides a vibrating platform for concrete precast components. Refer to Figures 1-10 As shown, it includes a chassis 11 and shock-absorbing legs 12 fixedly installed at the four corners of the top surface of the chassis 11. The tops of the four shock-absorbing legs 12 are fixedly installed with a vibrating table 13. Two vibrating motors 14 are symmetrically fixed to the bottom surface of the vibrating table 13. Two fixed boxes 21 are symmetrically fixed to the side edges of the top surface of the vibrating table 13. Transmission components are arranged inside both of the two fixed boxes 21. Two sets of clamping and scraping components are symmetrically arranged between the two sets of transmission components. A connection box 51 is fixedly installed on the side surface of the fixed box 21. A pulling component is arranged inside the connection box 51; Refer to Figure 1 、 Figure 3 、 Figure 4 As shown, the transmission component includes two fixed plates 25 symmetrically arranged inside the fixed box 21. The transmission component further includes a transmission gear 22 rotatably installed on the inner wall of the fixed box 21. Transmission racks 23 meshing with the transmission gear 22 are slidably installed on both the inner bottom surface and the inner top surface of the fixed box 21. A connecting plate 24 is fixedly installed at the end of the transmission rack 23. The fixed plate 25 is fixedly connected to the end of the connecting plate 24 away from the transmission rack 23. A slot 26 is formed on the side surface of the fixed plate 25. A slider 27 is slidably installed on the inner wall of the slot 26. The end of the shaft rod 31 is fixedly connected to the side surface of the slider 27. A first spring 28 is fixedly installed between the bottom surface of the slider 27 and the inner bottom surface of the slot 26. Two guiding openings 29 having the same width as the slot 26 are formed on the side surface of the fixed box 21; First, the staff can place the molds to be vibrated on the top surface of the vibrating table 13 and arrange them so that they are in a close-fitting state after arrangement, and both ends are respectively in contact with the side surfaces of the fixed boxes 21. The clamping and scraping components on both sides of the top surface of the vibrating table 13 can clamp the molds. The staff can add concrete raw materials into the molds and start the vibrating motors 14 to drive the vibrating table 13 through the shock-absorbing legs 12, so that the vibrating table 13 vibrates to form the concrete in the molds.

[0021] Refer to Figures 4-6As shown in the figure, the clamping and scraping assembly includes a shaft rod 31 arranged between the opposite side surfaces of two fixing plates 25. Two rotating sleeves 32 are rotatably sleeved on the outer wall of the shaft rod 31. A clamping plate 33 is fixedly installed on the outer wall of the rotating sleeve 32. A scraping plate 34 is fixedly installed at the bottom end of the clamping plate 33. The clamping and scraping assembly further includes a first torsion spring 35 sleeved at both ends of the shaft rod 31, and both ends of the first torsion spring 35 are fixedly connected to the shaft rod 31 and the rotating sleeve 32 respectively. Fixing blocks 36 are fixedly installed at one ends of the two rotating sleeves 32 away from each other. Positioning rods 37 corresponding to the fixing blocks 36 are fixedly installed on the side surfaces of the two sliders 27. A connecting frame 38 is fixedly installed between one ends of the two rotating sleeves 32 close to each other. The connecting frame 38 is U-shaped. Material storage boxes 15 corresponding to the scraping plates 34 are fixedly installed on both side surfaces of the vibrating table 13; When the transmission gear 22 rotates, it can drive the two transmission racks 23 and the connecting plate 24 to slide in opposite directions, so that the two fixing plates 25 can slide in the direction of approaching each other. During the sliding process of the two fixing plates 25, the shaft rod 31, the rotating sleeve 32, the clamping plate 33 and the scraping plate 34 can be synchronously slid along the guiding opening 29. At this time, the clamping plate 33 is in an inclined state under the action of the first torsion spring 35, and the inclination angle of the clamping plate 33 is fixed through the cooperation of the fixing block 36 and the positioning rod 37; when the clamping plate 33 contacts the mold, under the action of the thrust, the rotating sleeve 32, the clamping plate 33 and the scraping plate 34 can rotate to a vertical state, so that the clamping plate 33 fits against the side surface of the mold. At this time, the slider 27 can slide upward in the slot 26, ensuring that the clamping plate 33 can rotate normally; as the clamping plate 33 separates from the mold, under the action of the first torsion spring 35, the rotating sleeve 32 can reverse, and under the combined action of the fixing block 36 and the positioning rod 37, the rotating sleeve 32 can rotate to an inclined state. At this time, under the pulling force of the first spring 28, the slider 27 can slide downward along the slot 26, and the bottom surface of the scraping plate 34 can fit against the top surface of the vibrating table 13.

[0022] See Figure 6 、 Figure 7As shown, a fixed shell 41 is fixedly sleeved on the outer wall of the shaft rod 31 between two rotating sleeves 32. A limiting structure is arranged inside the fixed shell 41. The limiting structure includes a ratchet wheel 42 rotatably sleeved on the outer wall of the shaft rod 31, and the ratchet wheel 42 is located inside the fixed shell 41. One end of one of the two rotating sleeves 32 is fixedly connected to the side surface of the ratchet wheel 42. A rotating shaft 43 penetrates through the side surface of the fixed shell 41. A ratchet pawl 44 meshing with the ratchet wheel 42 is fixedly installed at one end of the rotating shaft 43 inside the fixed shell 41. A second torsion spring 45 is sleeved on the rotating shaft 43, and both ends of the second torsion spring 45 are fixedly connected to the rotating shaft 43 and the fixed shell 41 respectively. A pressing plate 46 is fixedly installed at one end of the rotating shaft 43 outside the fixed shell 41. An installation plate 47 corresponding to the pressing plate 46 is fixedly installed on the side surface of the fixed shell 41. A ejector rod 48 penetrates through the side surface of the installation plate 47. A second spring 49 is sleeved on the ejector rod 48, and both ends of the second spring 49 are fixedly connected to the installation plate 47 and the ejector rod 48 respectively; When the ejector rod 48 on the side surface of the fixed shell 41 slides to contact the mold, as the fixing plate 25 continues to move, the ejector rod 48 can push the pressing plate 46, and during the process of the pressing plate 46 being pushed, the rotating shaft 43 and the ratchet pawl 44 can be driven to rotate, so that the ratchet pawl 44 is separated from the ratchet wheel 42, and the limit on the ratchet wheel 42 and the rotating sleeve 32 can be released; when the transmission gear 22 rotates in the reverse direction, the two transmission racks 23 can slide in the reverse direction and the two shaft rods 31 at both ends move away from each other. When the shaft rod 31 moves, the ejector rod 48 can be separated from the side surface of the mold. At this time, under the action of the second spring 49, the ejector rod 48 can slide reversely along the installation plate 47 and the pressing plate 46 and the rotating shaft 43 can be reversed under the action of the second torsion spring 45, and the ratchet pawl 44 can mesh with the ratchet wheel 42 again; as the shaft rod 31 moves back to its original position, during the movement of the scraping plate 34 and the clamping plate 33, the scraping plate 34 can push the concrete overflowing from the top surface of the vibrating table 13, and when the shaft rod 31 returns to its original position, the concrete pushed by the scraping plate 34 can fall into the storage box 15 under the action of gravity for collection. When the scraping plate 34 pushes the concrete, the scraping plate 34 and the clamping plate 33 tend to reverse, and this reverse direction is the locking direction of the ratchet wheel 42 and the ratchet pawl 44. Therefore, the rotating sleeve 32, the clamping plate 33, and the scraping plate 34 cannot reverse, ensuring that the scraping plate 34 can stably scrape and collect the concrete overflowing on the vibrating table 13.

[0023] See Figures 8-10As shown in the figure, the pulling component includes a support rod 52 rotatably installed on the inner wall of the connection box 51. A winding disc 53 is fixedly sleeved on the outer wall of the support rod 52. A pulling rope 55 is arranged inside the winding disc 53. The pulling component further includes a third torsion spring 54 sleeved on the end of the support rod 52, and both ends of the third torsion spring 54 are fixedly connected to the support rod 52 and the connection box 51 respectively. The end of the support rod 52 is fixedly connected to the side surface of the transmission gear 22. One end of each of the two pulling ropes 55 away from the winding disc 53 passes through the side surface of the connection box 51 and is fixedly installed with a pulling plate 56. A positioning structure corresponding to the pulling rope 55 is arranged on the top surface of the connection box 51. The positioning structure includes a sliding plate 61 slidably installed on the inner bottom surface of the connection box 51, and the sliding plate 61 is fixedly sleeved on the outer wall of the pulling rope 55. An opening 62 corresponding to the sliding plate 61 is formed on the top surface of the connection box 51. A rotating frame 63 is rotatably installed on the inner wall of the opening 62. A limiting rod 64 is slidably installed on the inner bottom surface of the rotating frame 63. The bottom end of the limiting rod 64 is beveled. A third spring 65 is fixedly installed between the top surface of the limiting rod 64 and the inner top surface of the rotating frame 63. An operating rod 66 is fixedly installed on the top surface of the rotating frame 63. The staff can rotate the operating rod 66 to drive the rotating frame 63 to rotate in the opening 62. When the rotating frame 63 rotates, it can drive the limiting rod 64 to rotate synchronously, so that the limiting rod 64 is separated from the sliding plate 61, and the limitation on the sliding plate 61 is released. When the sliding plate 61 is released from the limitation, the winding disc 53 can rotate under the action of the third torsion spring 54 and wind up the pulling rope 55. After the use of the operating rod 66 is completed, the staff needs to reverse it to reset it to the vertical state; the rotation of the winding disc 53 can drive the support rod 52 and the transmission gear 22 to rotate; after the concrete is formed, the staff can pull the pulling plate 56. When the pulling plate 56 is pulled, it can drive the sliding plate 61 to slide through the pulling rope 55, and the winding disc 53 rotates. At this time, the operating rod 66 needs to be held and fixed. When the sliding plate 61 is pulled to the position of the limiting rod 64, under the action of the inclined surface at the bottom end of the limiting rod 64, the sliding plate 61 can drive the limiting rod 64 to slide upward to make way for the sliding plate 61, so that the sliding plate 61 passes through the limiting rod 64. After the sliding plate 61 passes through, the limiting rod 64 can be reset under the action of the third spring 65 to fix the sliding plate 61.

[0024] The working principle of the present invention is as follows: During use, first, the staff can place the mold that needs to be vibrated on the top surface of the vibrating table 13 and arrange it so that the molds are in a close-fitting state after arrangement, and both ends are respectively in contact with the side surfaces of the fixed box 21. Subsequently, the staff can rotate the operating rod 66 to drive the rotating frame 63 to rotate in the opening 62. When the rotating frame 63 rotates, the limiting rod 64 can be driven to rotate synchronously, so that the limiting rod 64 is separated from the sliding plate 61, releasing the limit on the sliding plate 61. When the sliding plate 61 is released from the limit, the winding disc 53 can rotate under the action of the third torsion spring 54 and wind up the pulling rope 55. After the use of the operating rod 66 is completed, the staff needs to reverse it to reset it to the vertical state; the rotation of the winding disc 53 can drive the support rod 52 and the transmission gear 22 to rotate. When the transmission gear 22 rotates, it can drive the two transmission racks 23 and the connecting plate 24 to slide in opposite directions, so that the two fixing plates 25 can slide towards each other. During the sliding process of the two fixing plates 25, the shaft rod 31, the rotating sleeve 32, the clamping plate 33 and the scraping plate 34 can be driven to slide synchronously along the guiding port 29. At this time, the clamping plate 33 is in an inclined state under the action of the first torsion spring 35, and the inclination angle of the clamping plate 33 is fixed through the cooperation of the fixing block 36 and the positioning rod 37. When the ejector rod 48 on the side surface of the fixed shell 41 slides to contact the mold, as the fixing plate 25 continues to move, the ejector rod 48 can push the abutting plate 46, and the rotating shaft 43 and the ratchet pawl 44 can be driven to rotate during the process of the abutting plate 46 being pushed, so that the ratchet pawl 44 is separated from the ratchet wheel 42, and the limit on the ratchet wheel 42 and the rotating sleeve 32 can be released. As the clamping plate 33 contacts the mold, under the action of the thrust, the rotating sleeve 32, the clamping plate 33 and the scraping plate 34 can rotate to the vertical state, so that the clamping plate 33 is in contact with the side surface of the mold. At this time, the slider 27 can slide upward in the slot 26, ensuring that the clamping plate 33 can rotate normally; The clamping plates 33 on both sides of the top surface of the vibrating table 13 can clamp the mold. The staff can add concrete raw materials into the mold and turn on the vibrating motor 14 to drive the vibrating table 13 through the shock-absorbing legs 12, so that the vibrating table 13 vibrates to form the concrete in the mold. After the concrete is formed, the staff can pull the pull plate 56. When the pull plate 56 is pulled, it can drive the sliding plate 61 to slide through the pull rope 55 and the winding disc 53 rotates. At this time, the operating rod 66 needs to be held for fixation. When the sliding plate 61 is pulled to the position of the limit rod 64, under the action of the inclined surface at the bottom end of the limit rod 64, the sliding plate 61 can drive the limit rod 64 to slide upward to make way for the sliding plate 61, so that the sliding plate 61 can pass through the limit rod 64 and be reset by the third spring 65 to fix the sliding plate 61. When the winding disc 53 rotates, it can synchronously drive the transmission gear 22 to rotate, so that the two transmission racks 23 can slide in the opposite direction and the two shaft rods 31 at both ends move away from each other. When the shaft rod 31 moves, the ejector rod 48 can be separated from the side surface of the mold. At this time, under the action of the second spring 49, the ejector rod 48 can slide reversely along the mounting plate 47 and the abutting plate 46 and the rotating shaft 43 can be reversed under the action of the second torsion spring 45, and the ratchet pawl 44 can be engaged with the ratchet wheel 42 again. As the clamping plate 33 is separated from the mold, under the action of the first torsion spring 35, the rotating sleeve 32 can be reversed, and with the cooperation of the fixed block 36 and the positioning rod 37, the rotating sleeve 32 can be rotated to an inclined state. At this time, under the pulling force of the first spring 28, the sliding block 27 can slide downward along the slot 26, and the bottom surface of the scraping plate 34 can be attached to the top surface of the vibrating table 13; As the shaft rod 31 moves and resets, during the movement of the scraping plate 34 and the clamping plate 33, the scraping plate 34 can push the concrete overflowing from the top surface of the vibrating table 13. When the shaft rod 31 is reset, the concrete pushed by the scraping plate 34 can fall into the storage box 15 under the action of gravity for collection. When the scraping plate 34 pushes the concrete, the scraping plate 34 and the clamping plate 33 will have a tendency to reverse, and this reverse direction is the locking direction of the ratchet wheel 42 and the ratchet pawl 44. Therefore, the rotating sleeve 32, the clamping plate 33, and the scraping plate 34 cannot be reversed, ensuring that the scraping plate 34 can stably scrape and collect the concrete overflowing on the vibrating table 13.
