[0001] The invention belongs to the technical field of concrete processing devices, and specifically refers to a block cutting device for building construction. Background Art

[0002] Prefabricated building blocks for construction are mostly large cubes when they are first produced. They need to be cut according to requirements when they are used. This cutting process is usually carried out at the construction site.

[0003] The current cutting devices have problems such as complex structure, high cost, complex control logic, and too many sensors, which makes the entire system large and sophisticated, and the failure rate also increases accordingly.

[0004] In order to further improve the practical value and promotional value of the device, the present invention focuses on proposing a building block cutting device for construction with a simple and reliable structure and stable operation. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a block cutting device for construction. Through the linkage of a double-cavity propulsion mechanism and a high-frequency reciprocating mechanism, during the reciprocating cutting process, the L-shaped push rod can complete the propulsion of the side push rod once at the end limit position through a unidirectional rotating component that can only be driven in one direction. By symmetrically arranging branch pipes, the L-shaped push rod can have the function of propulsing the side push rod at the limit positions at both ends, thereby greatly improving the cutting efficiency.

[0006] The technical solution adopted by the present invention is as follows: The present invention proposes a block cutting device for construction, including a double-chamber propulsion mechanism, a high-frequency reciprocating mechanism, a block cutting mechanism and a transverse movement mechanism, wherein the double-chamber propulsion mechanism is arranged on the block cutting mechanism, the high-frequency reciprocating mechanism is arranged on the block cutting mechanism, and the transverse movement mechanism is arranged at the bottom of the block cutting mechanism.

[0007] Furthermore, the double-chamber propulsion mechanism includes a double-chamber pipe assembly, a piston push rod assembly and a one-way rotation assembly. The double-chamber pipe assembly is arranged on the block cutting mechanism, the piston push rod assembly is snap-fitted and slidably arranged in the double-chamber pipe assembly, and the one-way rotation assembly is rotatably arranged on the double-chamber pipe assembly.

[0008] Through the one-way trigger type one-way rotating component, the block body can be pushed outward a unit distance after each cutting is completed, thereby achieving the technical effect of automatic feeding during the reciprocating cutting process.

[0009] Preferably, the double-lumen pipe assembly comprises a pipe support and a double-lumen pipe body, the pipe support is arranged on the block cutting mechanism, the double-lumen pipe body is snap-fitted into the pipe support, and the double-lumen pipe body consists of a central pipe and symmetrically distributed branch pipes.

[0013] The propulsion drive nut can be driven by a high-frequency reciprocating mechanism, but since the rotational resistance of the propulsion drive nut is greater than the resistance that needs to be overcome by the elastic deformation of the inner and outer ratchets, the propulsion wheel will not rotate with the propulsion drive nut when the L-shaped push rod is reset; since the threaded connection between the screw portion and the transverse slider has a self-locking function, when the side push rod of one side layer is pushed forward, the side push rod on the other side will not be pushed, thereby achieving the technical effect that the advancement of both sides can make the center push rod extend.

[0014] Furthermore, the high-frequency reciprocating mechanism comprises a transverse sliding component and a high-frequency reciprocating component, the transverse sliding component is slidably arranged on the block cutting mechanism, and the high-frequency reciprocating component is arranged on the transverse sliding component.

[0015] Preferably, the transverse sliding assembly includes a transverse slider and an L-shaped push rod, the transverse slider is provided with a longitudinal slide groove and a transverse slide groove which are perpendicular to each other, the transverse slider is slidably arranged on the block cutting mechanism through the transverse slide groove, and the L-shaped push rod is fixedly connected to the outer side of the transverse slider.

[0016] The L-shaped push rod will drive the propulsion wheel to rotate only when it moves to the end limit position. Therefore, the block body will not move during the cutting process, but will be pushed forward a certain distance only after the cutting is completed.

[0017] As a further preferred embodiment of the present invention, the high-frequency reciprocating component includes a reciprocating motor, a reciprocating wheel and a grooved slider, the reciprocating motor is arranged on the transverse slider, the reciprocating wheel is clamped on the output shaft of the reciprocating motor, the reciprocating wheel is provided with an eccentric boss, the grooved slider is arranged on the block cutting mechanism, the grooved slider is provided with a reciprocating slide groove, and the eccentric boss is clamped and slidably arranged in the reciprocating slide groove.

[0019] Furthermore, the block cutting mechanism includes a frame assembly and a saw blade assembly, and the saw blade assembly is arranged on the frame assembly.

[0020] Preferably, the frame assembly includes a base plate, a support leg and a block body, the support leg is arranged at the bottom of the base plate, the base plate is provided with a block limiting groove, the block body is slidably arranged in the block limiting groove, the pipe bracket is arranged on the base plate, and the transverse sliding block is slidably arranged on the base plate through the transverse sliding groove.

[0021] The saw blade assembly includes a frame bracket and a reciprocating saw blade. The frame bracket is slidably engaged in a longitudinal slide groove.

[0024] (1) Through the one-way trigger type one-way rotating assembly, the block body can be pushed outward a unit distance after each cutting is completed, thereby achieving the technical effect of automatic feeding during the reciprocating cutting process.

[0025] (2) The double-chamber pipe assembly and the piston push rod assembly form a hydraulic linkage mechanism. By pushing the side push rod on either side, the center push rod can be extended outward by a unit length, thereby pushing the block body and achieving the technical goal of automatic feeding.

[0026] (3) The propulsion drive nut can be driven by a high-frequency reciprocating mechanism. However, since the rotational resistance of the propulsion drive nut is greater than the resistance that needs to be overcome by the elastic deformation of the inner and outer ratchets, the propulsion wheel will not rotate with the propulsion drive nut when the L-shaped push rod is reset; since the threaded connection between the screw portion and the transverse slider has a self-locking function, when the side push rod of one side layer is pushed forward, the side push rod on the other side will not be pushed, thereby achieving the technical effect that the push on both sides can cause the center push rod to extend.

[0027] (4) The L-shaped push rod will drive the propulsion wheel to rotate only when it moves to the end limit position. Therefore, the block body will not move during the cutting process. Instead, the block body will be pushed forward a certain distance after the cutting is completed.

[0028] (5) Through the cooperation of the eccentric boss and the reciprocating groove on the reciprocating wheel, the longitudinal reciprocating drive of the frame bracket can be realized through the rotation of the reciprocating motor, and the reciprocating saw blade with high frequency reciprocating motion can complete the cutting of the block body while occupying a small space.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0045] like Figures 1 to 12 As shown, the present invention proposes a block cutting device for construction, including a double-chamber propulsion mechanism 1, a high-frequency reciprocating mechanism 2, a block cutting mechanism 3 and a transverse movement mechanism 4, the double-chamber propulsion mechanism 1 is arranged on the block cutting mechanism 3, the high-frequency reciprocating mechanism 2 is arranged on the block cutting mechanism 3, and the transverse movement mechanism 4 is arranged at the bottom of the block cutting mechanism 3.

[0046] The block cutting mechanism 3 includes a frame assembly 34 and a saw blade assembly 35 , and the saw blade assembly 35 is arranged on the frame assembly 34 .

[0047] The frame assembly 34 includes a base plate 36, a support leg 37 and a block body 38. The support leg 37 is arranged at the bottom of the base plate 36. The base plate 36 is provided with a block limiting groove 41. The block body 38 is slidably arranged in the block limiting groove 41. The pipe bracket 8 is arranged on the base plate 36. The transverse slider 26 is slidably arranged on the base plate 36 through the transverse sliding groove 47.

[0048] The saw blade assembly 35 includes a frame bracket 39 and a reciprocating saw blade 40 . The frame bracket 39 is slidably engaged in the longitudinal slide groove 31 . Saw blade positioning pins 42 are provided at the top and bottom of the frame bracket 39 . The reciprocating saw blade 40 is fixed by the saw blade positioning pins 42 .

[0049] The double-chamber propulsion mechanism 1 includes a double-chamber pipe assembly 5, a piston push rod assembly 6 and a one-way rotation assembly 7. The double-chamber pipe assembly 5 is arranged on the block cutting mechanism 3, the piston push rod assembly 6 is slidably arranged in the double-chamber pipe assembly 5, and the one-way rotation assembly 7 is rotatably arranged on the double-chamber pipe assembly 5.

[0050] Through the one-way trigger type one-way rotating assembly 7, the block body 38 can be pushed outward by a unit distance after each cutting is completed, thereby achieving the technical effect of automatic feeding during the reciprocating cutting process.

[0051] The double-lumen pipe assembly 5 includes a pipe support 8 and a double-lumen pipe body 9. The pipe support 8 is arranged on the block cutting mechanism 3. The double-lumen pipe body 9 is clamped in the pipe support 8. The double-lumen pipe body 9 consists of a central pipe 14 and symmetrically distributed branch pipes 15.

[0052] The piston push rod assembly 6 includes a central push rod 10 and a side push rod 11. The central push rod 10 is provided with a piston portion 16. The central push rod 10 is slidably engaged in the central pipe 14 through the piston portion 16. The side push rod 11 is composed of a piston portion 17 and a screw portion 18. The side push rod 11 is slidably engaged in the branch pipe 15 through the piston portion 17. The piston portion 17 cannot rotate in the branch pipe 15.

[0053] The double-chamber pipe assembly 5 and the piston push rod assembly 6 form a hydraulic linkage mechanism. By pushing the side push rod 11 on either side, the central push rod 10 can be extended outward by a unit length, thereby pushing the block body 38 and achieving the technical goal of automatic feeding.

[0054] The one-way rotating component 7 includes a propulsion drive nut 12 and a propulsion wheel 13. The propulsion drive nut 12 is provided with a nut rotating ring 19. The propulsion drive nut 12 is rotatably arranged at the end of the branch pipe 15 through the nut rotating ring 19. The propulsion drive nut 12 is also provided with a nut step groove 20. The outer part of the nut step groove 20 is evenly distributed with external ratchets 21 in a ring shape. The propulsion wheel 13 is provided with a wheel rotating ring 22. The propulsion wheel 13 is rotatably arranged on the propulsion drive nut 12 through the wheel rotating ring 22. The interior of the propulsion wheel 13 is also evenly distributed with internal ratchets 23 matching the external ratchets 21 in a ring shape.

[0055] The propulsion drive nut 12 can be driven by the high-frequency reciprocating mechanism 2, but since the rotational resistance of the propulsion drive nut 12 is greater than the resistance that needs to be overcome by the elastic deformation of the inner ratchet 23 and the outer ratchet 21, the propulsion wheel 13 will not rotate with the propulsion drive nut 12 when the L-shaped push rod 27 is reset; since the threaded connection between the screw portion 18 and the transverse slider 26 has a self-locking function, when the side push rod 11 of one side layer is pushed forward, the side push rod 11 on the other side will not be pushed, thereby achieving the technical effect that the advancement of both sides can make the center push rod 10 extend.

[0056] The high-frequency reciprocating mechanism 2 includes a transverse sliding component 24 and a high-frequency reciprocating component 25 . The transverse sliding component 24 is slidably disposed on the block cutting mechanism 3 , and the high-frequency reciprocating component 25 is disposed on the transverse sliding component 24 .

[0057] The transverse sliding assembly 24 includes a transverse slider 26 and an L-shaped push rod 27. The transverse slider 26 is provided with a longitudinal slide groove 31 and a transverse slide groove 47 which are perpendicular to each other. The transverse slider 26 is slidably arranged on the block cutting mechanism 3 through the transverse slide groove 47. The L-shaped push rod 27 is fixedly connected to the outer side of the transverse slider 26.

[0058] The L-shaped push rod 27 will drive the propulsion wheel 13 to rotate only when it moves to the end limit position. Therefore, the block body 38 will not move during the cutting process, but will be pushed forward a certain distance after the cutting is completed.

[0059] The high-frequency reciprocating component 25 includes a reciprocating motor 28, a reciprocating wheel 29 and a grooved slider 30. The reciprocating motor 28 is arranged on the transverse slider 26. The reciprocating wheel 29 is clamped on the output shaft of the reciprocating motor 28. An eccentric boss 32 is provided on the reciprocating wheel 29. The grooved slider 30 is arranged on the block cutting mechanism 3. A reciprocating groove 33 is provided on the grooved slider 30. The eccentric boss 32 is clamped and slidably arranged in the reciprocating groove 33.

[0060] Through the cooperation of the eccentric boss 32 and the reciprocating groove 33 on the reciprocating wheel 29, the longitudinal reciprocating drive of the frame bracket 39 can be realized through the rotation of the reciprocating motor 28, and the reciprocating saw blade 40 with high frequency reciprocating motion can complete the cutting of the block body 38 while occupying a small space.

[0061] The transverse movement mechanism 4 includes a screw module 43 and a connecting rod 44 . The two transverse sliders 26 are connected by the connecting rod 44 . The screw module 43 is composed of a sliding part 45 and a base part 46 . The base part 46 is arranged at the bottom of the bottom plate 36 , and the base part 46 is arranged on the connecting rod 44 .

[0062] When in use, the user first starts the reciprocating motor 28. When the reciprocating wheel 29 rotates, the frame bracket 39 fixed to the reciprocating slide 33 can move longitudinally through the cooperation of the eccentric boss 32 and the reciprocating slide 33. The frame bracket 39 reciprocates with the reciprocating saw blade 40, so that the block body 38 can be cut when it approaches and contacts the block body 38.

[0063] Then, the sliding portion 45 on the screw module 43 can slide the connecting rod 44 and the two sets of horizontal slide blocks 26 horizontally, and the reciprocating saw blade 40 contacts the block body 38 to cut the block body 38.

[0064] When the cutting is completed, the transverse slider 26 will continue to slide a certain distance. When the L-shaped push rod 27 contacts the outer wall of the propulsion wheel 13, the propulsion wheel 13 will be pushed to rotate. The driving form between the propulsion wheel 13 and the L-shaped push rod 27 can be friction driven or gear rack driven. Due to the existence of the outer ratchet 21 and the inner ratchet 23, the propulsion drive nut 12 and the propulsion wheel 13 can only rotate relative to each other in a single direction. Therefore, in the process of the L-shaped push rod 27 sliding toward the outside, the L-shaped push rod 27 will drive the propulsion drive nut 12 to rotate through the propulsion wheel 13. Since the side push rod 11 can only slide but not rotate in the branch pipe 15, the propulsion drive nut 12 will push the side push rod 11 toward the inside of the branch pipe 15 for a certain distance during the rotation process.

[0065] Since the threaded transmission of the screw portion 18 and the propulsion drive nut 12 has a self-locking function, when the side push rod 11 on one side slides, the side push rod 11 on the other side will not push. At this time, the central push rod 10 will extend outward to a certain extent, thereby pushing the block body 38 outward and completing the automatic feeding of the block body 38.

[0066] When the lateral slider 26 slides to the limit position, it is controlled by the screw module 43 to slide in the opposite direction to the limit position. The L-shaped push rod 27 will rotate with the propulsion wheel 13 during the resetting process. However, since the rotation resistance of the propulsion drive nut 12 is greater than the resistance that needs to be overcome by the elastic deformation of the inner ratchet 23 and the outer ratchet 21, the propulsion wheel 13 will not rotate with the propulsion drive nut 12 during this process.

[0067] When the transverse slider 26 slides to the extreme position at the other end, cutting is completed again. After that, the L-shaped push rod 27 on the other side drives the one-way rotating component 7 to rotate in the same working process as the above process.

[0068] During the reciprocating sliding of the sliding part 45, the block body 38 can be segmented, and after each segmentation, the block body 38 will automatically move forward until all the cutting is completed.

[0069] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0070] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
