Description

Technical Field

[0001] The invention belongs to the technical field of precast concrete panels, and in particular relates to a precast concrete panel shearing machine. Background Art

[0002] Precast concrete panels are a type of prefabricated component commonly used in the construction industry. They are concrete structures that are prefabricated in factories or other places other than construction sites. After being transported to the construction site, these precast panels can be installed in place by lifting machinery, which can speed up the construction schedule and improve the quality and consistency of the structure. However, precast concrete panels may need to be sheared during the manufacturing process or before use. Precast panels may need to be sized according to specific building design and construction requirements. Shearing can make precast panels reach the precise size required to adapt to different installation locations. Different construction projects may require precast panels of specific shapes, such as special-shaped panels or panels with special edges to meet design requirements or aesthetic standards. At the same time, shearing can remove excess parts of precast panels, optimize their structure, reduce material waste, and improve the overall performance of the structure. Therefore, precast concrete panels require special shearing machines to optimize them for reuse.

[0003] However, there are some problems with the prior art: however, the blade used by the current precast concrete panel shearing machine is a whole piece, which results in the need to repeatedly reprocess the precast concrete panel after cutting when the precast concrete panel needs to be cut into multiple small pieces, which makes it impossible to shear quickly and cannot meet the current situation. Secondly, the shearing machine can only shear in one direction, which results in the need to manually hold the precast panel and constantly adjust the position when processing special-shaped panels. This type of shearing is inefficient and has certain limitations. Therefore, we propose a precast concrete panel shearing machine. Summary of the invention

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figures 1 to 10 As shown, a concrete precast slab shearing machine provided by an embodiment of the present invention comprises: a processing bed 1, a lifting seat 2 is provided on the upper surface of the processing bed 1 for lifting, a cutting blade is provided at the bottom of the lifting seat 2, and the cutting blade is composed of a plurality of shear blades 3; a partition assembly 10, the partition assembly 10 is composed of a partition driving component 101 and a transmission component 102, the partition driving component 101 is arranged on one side of the lifting seat 2, and the plurality of shear blades 3 are movably connected to the partition driving component 101, so that the plurality of shear blades 3 are separated from or approached by the partition driving component 101, and the transmission component 102 is connected to the partition driving component 102. Component 101 is transmission connected; the angle adjustment component 4 is arranged at one end of the upper surface of the lifting seat 2, and the transmission component 102 is arranged between the angle adjustment component 4 and the partition driving component 101, so that the angle adjustment component 4 is rotationally connected to the partition driving component 101 through the transmission component 102, and multiple groups of shearing blades 3 are rotationally arranged at the bottom of the lifting seat 2 through the angle adjustment component 4, and the middle part of the upper surface of the multiple groups of shearing blades 3 is provided with a connecting component 9, the shearing blades 3 are rotationally connected to the lifting seat 2 through the connecting component 9, and the connecting component 9 is movably connected to the partition driving component 101.

[0037] By designing that the cutting piece is composed of multiple groups of shear blades 3, the multiple groups of shear blades 3 can be separated from each other by the separation driving component 101, so that a gap can be generated between two adjacent groups of shear blades 3, and rotation can be achieved through the angle adjustment component 4, so that the shearing direction of the multiple groups of shear blades 3 on the precast panels is changed, thereby, the concrete precast panels can be cut into different shapes.

[0038] As described above, since multiple sets of shear blades 3 can cut the concrete precast panels into different shapes through the separation drive component 101 and the angle adjustment component 4, a single concrete precast panel shearing machine can achieve multiple cutting methods, effectively improving the practicality and functional diversity of the equipment.

[0039] Furthermore, two adjacent sets of shear blades 3 are provided with a stabilizing groove 6 on the same side, and a stabilizing plate 5 is fixedly installed at one end of one set of shear blades 3, and the stabilizing plate 5 is arranged correspondingly to the stabilizing groove 6;

[0040] like Figures 1 to 10 As shown, through the design in which the stabilizing plate 5 and the stabilizing groove 6 are arranged in correspondence, when the angles of multiple groups of shear blades 3 are synchronously rotated to a horizontal state, the adjacent shear blades 3 can move the stabilizing plate 5 into the stabilizing groove 6, so that when the multiple groups of shear blades 3 are synchronously downward for shearing work, the stabilizing plate 5 and the stabilizing groove 6 can further improve the stability of the adjacent shear blades 3 during shearing, thereby effectively improving the stability of the modularly designed shear blades 3 during shearing.

[0041] It should be noted that one side of one of the plurality of shear blades 3 is not provided with a stabilizing groove 6. Figure 1 As shown, one set of shear blades 3 is located at the far left.

[0042] Further, the separation driving component 101 includes a plurality of sets of pitch-changing plates 1011, a plurality of sets of adjustment holes 7 are provided at the lower end of one side of the lifting seat 2, the pitch-changing plates 1011 are slidably installed inside the adjustment holes 7, the plurality of sets of pitch-changing plates 1011 are all inclined, and the inclination angle increases from left to right, a pitch-changing cavity is provided on the upper surface of the pitch-changing plates 1011, and the connecting component 9 is located inside the pitch-changing cavity; a mounting groove is provided on one side of the lifting seat 2, a remote control motor 1012 is provided inside the mounting groove, a screw rod 1013 is fixedly installed at one end of the output shaft of the remote control motor 1012, an adjustment plate 1014 is connected to the outer side of the screw rod 1013 by a thread, and the plurality of sets of pitch-changing plates 1011 are all fixedly connected to the adjustment plate 1014;

[0043] It should be noted that, combined with Figure 2 and Figure 5As shown, no pitch variable plate 1011 is arranged above the shear blade 3 below the angle adjustment assembly 4 , so the position of the shear blade 3 below the angle adjustment assembly 4 is fixed, while the remaining shear blades 3 are all provided with pitch variable plates 1011 above them.

[0044] like Figures 1 to 10 As shown, due to the design that the tilt angles of the multiple sets of variable pitch plates 1011 gradually increase from left to right, when the multiple sets of variable pitch plates 1011 move at the same time, since the connecting component 9 is located inside the variable pitch cavity, the spacings between the multiple sets of shear blades 3 are changed synchronously and at the same distance. Therefore, gaps are generated between the multiple sets of shear blades 3, which facilitates the subsequent rotation of the multiple sets of shear blades 3 through the angle adjustment component 4. Therefore, before the multiple sets of shear blades 3 rotate, they need to be moved by the separation drive component 101 to avoid collision between the multiple sets of shear blades 3 when rotating, thereby shortening their service life.

[0045] Further, the connecting assembly 9 includes a connecting column 902 and a transmission column 901, the connecting column 902 is elastically connected to the transmission column 901, and the upper end of the transmission column 901 is transmission-connected to the angle adjustment assembly 4, a plurality of avoidance holes are provided at the bottom of the lifting seat 2, and the avoidance holes are communicated with the inside of the adjustment hole 7, the upper end of the transmission column 901 passes through the inside of the avoidance holes to the inside of the variable pitch cavity, and the lower end of the connecting column 902 is fixedly connected to the shear blade 3;

[0046] like Figures 1 to 10 As shown, through the design that the upper end of the transmission column 901 passes through the inside of the avoidance hole to the inside of the variable pitch cavity, the connecting column 902 can slide along the axial direction of the avoidance hole through the design of the variable pitch plate 1011 and the avoidance hole, thereby creating gaps between multiple groups of shear blades 3.

[0047] Furthermore, a sliding column 908 is fixedly installed in the middle of the upper surface of the connecting column 902, a deceleration groove is opened at the bottom of the transmission column 901, the upper end of the sliding column 908 is vertically slidably installed inside the deceleration groove, and a deceleration pad 909 is fixedly installed at the upper end of the deceleration groove, and the sliding column 908 is located at the bottom of the deceleration pad 909, and multiple groups of connecting rods 906 are rotatably connected to the upper surface of the connecting column 902, and the multiple groups of connecting rods 906 are arranged in a ring and equidistantly, and the upper ends of the multiple groups of connecting rods 906 are rotatably connected to sliding seats 905, and the sliding seats 905 are slidably installed at the bottom of the transmission column 901, and multiple groups of spring push rods 907 are fixedly installed around the bottom of the transmission column 901, and one end of the piston rod of the spring push rod 907 is fixedly connected to the sliding seat 905; multiple groups of first deceleration blocks 903 are slidably connected to the bottom of the transmission column 901, and the multiple groups of sliding seats 905 are fixedly installed on the side away from the center of the transmission column 901, and the second deceleration blocks 904 and the first deceleration blocks 903 are both arranged in an arc shape;

[0048] like Figure 3 and Figure 8 As shown, by the design that the sliding column 908 is located at the bottom of the relief pad 909, when the shear blade 3 below is sheared by extrusion, the sliding column 908 reduces the vertical pressure by extruding the relief pad 909, and relies on the multiple groups of second relief blocks 904 and first relief blocks 903 arranged in a ring. The second relief block 904 relies on the elastic relief pad 909 to move a short distance, thereby being squeezed with the first relief block 903, and the multiple groups of second relief blocks 904 and first relief blocks 903 arranged in a ring can differentiate the vertical extrusion force of the shear blade 3, thereby reducing the extrusion force of the transmission column 901 on the angle adjustment component 4, thereby effectively improving the service life of both parties.

[0049] It should be noted that, since the first relief block 903 and the second relief block 904 are both designed to be arc-shaped, the second relief block 904 can better fit inside the first relief block 903, thereby more fully contacting the differentiated extrusion force.

[0050] It is worth noting that the internal spring force of the spring top rod 907 is set toward the center of the transmission column 901. Therefore, the sliding seat 905 can automatically approach the transmission column 901 under the action of the spring top rod 907, thereby effectively preventing the sliding column 908 from squeezing the bottom of the mitigation pad 909 when the shear blade 3 is not in use.

[0051] Furthermore, the angle adjustment component 4 includes multiple sets of main gears 405 and multiple sets of driven gears 406, the main gears 405 and the driven gears 406 are arranged in pairs, and the main gears 405 are arranged in pairs with the transmission column 901, the upper end of the transmission column 901 is fixedly installed at the bottom center of the main gear 405, a transmission groove is opened inside the lifting seat 2, multiple sets of avoidance holes are connected to the inside of the transmission groove, and multiple sets of driven gears 406 are arranged at equal distances, the driven gears 406 are rotatably installed at the lower end of the transmission groove, and the upper surfaces of the multiple sets of driven gears 406 are jointly provided with sprocket synchronization mechanisms 401, the multiple sets of main gears 405 are movably installed inside the transmission groove, the multiple sets of main gears 405 and the driven gears 406 are arranged at the same level, and one set of main gears 405 is arranged at the same level. 05 and one of the driven gears 406 are meshed with each other, and one of the main gears 405 is rotatably installed at the lower end of the transmission slot; a protective shell 402 is provided at one end of the upper surface of the lifting seat 2, and a lifting slot is provided at the bottom of the protective shell 402, a reset spring 12 is fixedly installed at the upper end of the lifting slot, a servo motor 403 is fixedly installed at the lower end of the reset spring 12, and a lifting sleeve 13 is fixedly provided on the outer side of the servo motor 403, a docking hole is provided at one end of the upper surface of the lifting seat 2, and the docking holes are communicated with the lifting slot and the inside of the transmission slot, a multilateral docking block 404 is fixedly installed at one end of the output shaft of the servo motor 403, a docking slot is provided in the middle of the upper surface of one of the main gears 405, and the multilateral docking block 404 is engaged in the docking slot;

[0052] It should be noted that the sprocket synchronization mechanism 401 mentioned above adopts a plurality of sprockets and chains to achieve synchronous rotation of the plurality of sprockets, thereby achieving synchronous rotation of the plurality of driven gears 406 .

[0053] like Figures 1 to 10 As shown, the main gear 405 and the driven gear 406 are designed to be arranged at the same level. The main gear 405 is matched with the pitch change plate 1011 and the transmission column 901, close to the driven gear 406, and meshes with it. When multiple groups of driven gears 406 rotate simultaneously through the sprocket synchronization mechanism 401, multiple groups of shear blades 3 can be synchronously adjusted in angle.

[0054] By providing a liftable servo motor 403, a modular design is achieved. When the servo motor 403 is damaged and needs to be repaired, the servo motor 403 can be easily disassembled and maintained separately. Therefore, the servo motor 403 with this modular design is more convenient.

[0055] It is worth mentioning that, through the design of the multilateral docking block 404 and the docking groove, the multilateral docking block 404 can fit more closely into the docking groove due to its multilateral characteristics, and when the multilateral docking block 404 is slightly misaligned with the docking groove, the output shaft of the servo motor 403 does not need to rotate too much to complete the docking, thereby improving the convenience of docking the servo motor 403 with one set of main gears 405.

[0056] It should be noted that the servo motor 403 can drive the main gear 405 to rotate forward and reversely, so that the angle rotation direction of multiple sets of shearing blades 3 can be adjusted arbitrarily, thereby improving the freedom of adjusting the angle of the shearing blades 3.

[0057] Specifically, Figure 1 and Fig.10 As shown, except for one group of main gears 405 , the upper surfaces of the remaining main gears 405 are all provided with fine-tuning components 15 , and the main gears 405 are detachably arranged with the transmission column 901 through the fine-tuning components 15 .

[0058] like Figure 1 and Fig.10 As shown, the fine-tuning assembly 15 mentioned above includes a first fastening rod 1501 and a second fastening rod 1502. The first fastening rod 1501 is rotatably installed at the center of the upper surface of the transmission column 901, and the second fastening rod 1502 is rotatably installed at the center of the upper surface of the main gear 405. A plurality of through holes are provided on the upper surface of the lifting seat 2, and the interior of the through holes is connected to the interior of the transmission groove. The second fastening rod 1502 is located inside the through holes. The main gear 405 and the second fastening rod 1502 are both provided with through holes in their centers. The first fastening rod 1501 passes through the through hole to the top of the lifting seat 2, and the upper end of the outer side of the first fastening rod 1501 is threadedly connected with a fastening plate 1503.

[0059] Through the fine-tuning component 15 designed as above, the angles of multiple sets of shear blades 3 can be adjusted separately with the transmission column 901 connected above, so as to further realize the freedom of modular design of multiple sets of shear blades 3. Therefore, the angles of multiple sets of shear blades 3 can be changed differently, so as to be combined with each other, which can facilitate the shearing of irregular concrete precast panels that need to be sheared, thereby effectively improving the practicality and functional diversity of the concrete precast panel shearing machine.

[0060] Furthermore, the transmission component 102 includes two groups of synchronous wheels 1023 and a winding wheel 1025, wherein one group of synchronous wheels 1023 is fixedly installed between the output shaft of the remote control motor 1012 and the screw rod 1013, a protective shell 1021 is fixedly installed on one side of the lifting seat 2, a protective groove is provided inside the protective shell 1021, the two groups of synchronous wheels 1023 are rotatably installed inside the protective groove, and a first synchronous belt 1024 is commonly sleeved between the two groups of synchronous wheels 1023, a mounting shell 1022 is fixedly installed on one end of one side of the protective shell 1021, and the interior of the mounting shell 1022 is communicated with the protective groove, the other group of synchronous wheels 1023 is fixedly connected to the winding wheel 1025, and the winding The wheel 1025 is rotatably mounted inside the mounting shell 1022, and a pull rope 1026 is wound around the outside of the winding wheel 1025. A threading hole is provided on the upper surface of the mounting shell 1022, and an avoidance groove is provided on one side of the protective shell 402. One end of the lifting sleeve 13 passes through the avoidance groove to the outside of the protective shell 402, and one end of the pull rope 1026 passes through the threading hole and is fixedly connected to the lifting sleeve 13. A reset rod 14 is fixedly mounted at the center of one side of the winding wheel 1025, a reset groove is provided at one end of the mounting shell 1022, and one end of the reset rod 14 is rotatably mounted inside the reset groove, and a spring spring 8 is fixedly mounted inside the reset groove, and one end of the spring spring 8 is fixedly connected to the reset rod 14.

[0061] like Figures 1 to 10 As shown, through the design of the winding wheel 1025 and the pull rope 1026, when the distance between the multiple sets of shear blades 3 is changed and increased by the pitch change plate 1011, the remote control motor 1012 can realize the winding wheel 1025 controlling the pull rope 1026 to pull the servo motor 403 downward through the cooperation of the two sets of synchronous wheels 1023 and the first synchronous belt 1024, so that the servo motor 403 automatically docks with one of the sets of main gears 405, and then the staff can control the servo motor 403 to rotate.

[0062] Through the design of the clockwork spring 8 and the reset rod 14, when it is necessary to combine multiple sets of shear blades 3 to form one blade, the servo motor 403 moves upward through the force of the reset spring 12, and the winding wheel 1025 can automatically rotate under the action of the clockwork spring 8 and the reset rod 14, thereby winding up the pull rope 1026 to prevent the pull rope 1026 from loosening.

[0063] Specifically, Figures 1 to 9 As shown, a replacement assembly 11 is fixedly installed at the bottom of the multiple sets of main gears 405.

[0064] like Fig. 9As shown, the replacement component 11 mentioned above includes a gear ring 1101 and a transmission gear 1105, a rotation groove is opened around the bottom of the transmission column 901, and the gear ring 1101 is rotatably installed inside the rotation groove, multiple groups of first deceleration blocks 903 arranged in a ring are fixedly connected to the bottom of the gear ring 1101, multiple groups of positioning seats 1104 are fixedly installed on the bottom of the lifting seat 2, and rotating grooves connected to each other are opened on both sides of the positioning seats 1104, and the transmission gear 1105 is rotatably installed inside the rotating groove, and the bottom center of multiple groups of driven gears 406 are fixedly installed with a linkage rod 1102, and the linkage rod 1102 passes through the lower end of the transmission groove to the bottom of the lifting seat 2, a set groove is opened at the lower end of the outer side of the linkage rod 1102, and another group of set grooves is opened on the outer side of the transmission gear 1105, and a second synchronous belt 1103 is commonly set between the two groups of set grooves.

[0065] like Figures 1 to 9 As shown, through the design of the toothed ring 1101, the transmission gear 1105, the linkage rod 1102 and the second synchronous belt 1103, when the shear blade 3 drives the transmission column 901 to move through the pitch change plate 1011, and makes the main gear 405 approach the driven gear 406 and mesh with it, at this moment, the toothed ring 1101 will also approach the transmission gear 1105 and mesh with it, so that when the servo motor 403 drives the driven gear 406 to rotate through the sprocket synchronization mechanism 401, the transmission gear 1105 drives the toothed ring 1101, so that the multiple groups of first deceleration blocks 903 arranged in a ring are replaced in position, thereby avoiding the first deceleration block 903 from being used for a long time and multiple times. By using them alternately, the cycle of repairing and replacing the first deceleration block 903 can be slowed down, thereby extending the service life of each first deceleration block 903.

[0066] It should be noted that the multiple sets of first deceleration blocks 903 mentioned above require the shear blade 3 to be rotated 90 degrees for replacement, and the shear blade 3 is commonly adjusted by rotating 90 degrees. Therefore, the first deceleration blocks 903 can only be replaced alternately after the shear blade 3 is rotated 90 degrees.

[0067] Secondly, when the shear blade 3 has not rotated ninety degrees, the position of the first deceleration block 903 will not be aligned with the second deceleration block 904, so that the second deceleration block 904 relies on the maximum sliding distance at the bottom of the transmission column 901 to reduce the vertical squeezing force of the sliding column 908 on the transmission column 901.

[0068] like Fig. 9 As shown, one side of the positioning seat 1104 is arranged in an arc shape, and one side of the positioning seat 1104 relies on the arc to fit around the outer lower end of the transmission column 901. Therefore, the positioning seat 1104 relies on the characteristics of the arc on one side to stably fit with the transmission column 901, thereby ensuring the stability of the gear ring 1101 and the transmission gear 1105 when they are meshed and connected.

[0069] The above embodiments are only used to help understand the method and core idea of ​​the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
