Description

Technical Field

[0001] The present invention relates to the technical field of cement precast slab processing, and particularly to a cement precast slab processing device. Background Art

[0002] At present, with the booming development of the construction industry, cement precast slabs have become indispensable building components in projects such as bridge and house construction due to their advantages of high production efficiency and stable quality. The grinding process, as a key link in cement precast slab processing, directly affects the flatness, smoothness of the precast slab surface and the fit degree of subsequent assembly, and plays a decisive role in the overall quality of the construction project. At present, most of the common cement precast slab grinding equipment on the market has a fixed-stroke design for its horizontal grinding mechanism. The horizontal moving distance of the grinding head of this kind of equipment is set as a fixed value at the factory and it is difficult to dynamically adjust according to the actual size of the precast. In actual production, the requirements for the width and thickness of cement precast slabs vary greatly in different engineering projects. When using this kind of fixed-stroke grinding equipment to process precast slabs of different sizes, the grinding head will generate a large number of ineffective idle strokes in the non-precast slab surface area. For example, when grinding a narrow-sized precast slab, the grinding head will still operate according to the preset stroke and move meaninglessly in the blank area beyond the width of the precast slab. This not only wastes the operation time of the equipment, greatly reduces the production efficiency, but also makes the motor, transmission components, etc. of the grinding equipment run in an unnecessary state for a long time, accelerating the wear and aging of the equipment, and thus increasing the energy consumption and maintenance cost of the equipment.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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.

[0018] Refer to Figures 1-11 , a cement precast slab processing equipment, including a processing equipment platform 1, a support seat 2, a connecting piece 12 and a grinding system 5. Support seats 2 are fixedly installed on both sides of the top of the processing equipment platform 1. A guide plate 7 is arranged between the two support seats 2. The guide plate 7 is used to assist in connecting the connecting piece 12, provide a fulcrum for the connecting piece 12, and at the same time play a role in limiting and guiding, so that the connecting piece 12 can only slide along the guide plate 7. The connecting piece 12 is slidably installed on the outer wall of the guide plate 7. The connecting piece 12 is mainly used to connect the support seat 2 and the grinding system 5, lap the grinding system 5 between the support seats 2, and at the same time cooperate with other structures to control the grinding system 5 to grind the cement precast slab. A first lead screw 8 is arranged inside the connecting piece 12. There are two first lead screws 8. A control mechanism for controlling the connecting piece 12 to move in different directions is arranged between the connecting piece 12 and the first lead screw 8. A grinding system 5 is arranged on one side of the connecting piece 12. The processing equipment platform 1, the support seat 2, the connecting piece 12 and the grinding system 5 are all prior arts, and even include a driving system for the cement precast slab. Therefore, the specific structures and principles thereof will not be described in detail one by one; The control mechanism includes a connection block 14 threadedly mounted on the outer wall of the first lead screw 8. The connection block 14 is rotatably mounted on the inner wall of the connecting member 12. With such a design, it can be ensured that when the connection block 14 is relatively fixed to the connecting member 12, the first lead screw 8 can drive the connecting member 12 to move. When the connection block 14 rotates relative to the connecting member 12, the first lead screw 8 can drive the connection block 14 to rotate, and at the same time, the rotation of the connection block 14 will not affect the connecting member 12. Second lead screws 24 are provided at the tops of the connection blocks 14. Engagement mechanisms are provided between the second lead screws 24 and the second gears 17. The second gears 17 are threadedly mounted on the outer walls of the second lead screws 24. With such a design, the rotation of the second gears 17 can drive the second lead screws 24 to slide up and down. Third gears 18 are provided on one side of the second gears 17. The second gears 17 are meshed with the third gears 18. The diameter of the second gear 17 is smaller than that of the third gear 18. This is to adjust the rotation speed of the second gear 17, so that when the third gear 18 rotates one week, the second gear 17 can rotate multiple weeks, thereby quickly controlling the up and down movement of the second lead screw 24. A first connecting plate 19 or a second connecting plate 20 is provided between the third gears 18. The first connecting plate 19 and the second connecting plate 20 only come into contact when the connecting member 12 moves to a certain position. When contacting the first connecting plate 19 or the second connecting plate 20, the movable tooth block 22 on the side wall of the second connecting plate 20 will be meshed with the tooth block on the outer wall of the third gear 18, thereby controlling the rotation of the third gear 18. One end of the second connecting plate 20 is fixedly installed with a first side plate 10. The first side plate 10 is rotatably mounted on the outer walls of the two first lead screws 8. One end of the first connecting plate 19 is fixedly installed with a second side plate 11. The second side plate 11 is slidably mounted on the outer wall of the first lead screw 8. An adjusting mechanism is provided at the bottom end of the second side plate 11.

[0019] Through the control mechanism, when the third gear 18 meshes with the movable tooth block 22 on the side wall of the first connecting plate 19, it is possible to control the relative fixation between one of the first lead screws 8 and the connecting member 12, and the relative rotation between the other first lead screw 8 and the connecting member 12, thereby changing the driving direction of the connecting member 12, so that the connecting member 12 changes from being controlled by one of the first lead screws 8 to being controlled by the other first lead screw 8. Since the rotation directions of the first lead screws 8 are opposite, the driving direction of the connecting member 12 changes, enabling the grinding system 5 to automatically change the movement direction when moving to one side of the second side plate 11 and the first side plate 10. When the first connecting plate 19 disengages from between the third gears 18, the third gears 18 will not rotate at this time, so the movement direction of the grinding system 5 will not change. When the third gear 18 meshes with the movable tooth block 22 on the side wall of the second connecting plate 20, the movement direction of the connecting member 12 can be changed again, thereby realizing the reciprocating movement of the connecting member 12, and the movement distance can be adjusted according to the position of the second side plate 11, thus reducing the idling of the grinding system 5 and improving the working efficiency of the device.

[0020] The adjusting mechanism includes a second baffle 4 provided at the bottom end of the second side plate 11. One side of the second baffle 4 can be set as a plane, or rollers can be added. If rollers are added, it can play a guiding role, enabling the precast concrete slab to move smoothly between the first baffle 3 and the second baffle 4. However, it will increase the cost. At the same time, due to the small solid particles generated by grinding, it is also easy for the solid small particles to enter the inside of the rollers, resulting in jamming and increasing the maintenance cost. Considering comprehensively, a plane is preferred in the present invention. One side of the second baffle 4 abuts against the precast concrete slab, and a control rod 6 is rotatably installed on the other side of the second baffle 4. The control rod 6 passes through one of the support seats 2 and extends to one side of the support seat 2. The control rod 6 is threadedly connected to the support seat 2. With such a design, the position of the second baffle 4 can be adjusted by rotating the control rod 6 to limit the precast concrete slab, so that the precast concrete slab is located between the first baffle 3 and the second baffle 4, and the position of the second side plate 11 is controlled according to the size of the precast concrete slab, thereby realizing the reverse movement of the grinding system 5 when grinding one side of the precast concrete slab.

[0021] In summary, through the provided control mechanism, the position of the second side plate 11 can be moved, thereby changing the moving distance of the grinding system 5, enabling the grinding system 5 to correspondingly adjust the moving distance when grinding precast concrete slabs of different widths, so that the grinding system 5 only moves on the surface of the precast concrete slab during horizontal movement, avoiding the problem that the horizontal grinding mechanism of traditional grinding equipment mostly adopts a fixed stroke design, the horizontal moving distance of the grinding head is a preset value, and it cannot be dynamically adjusted according to the actual size of the precast member, resulting in a large number of ineffective empty strokes and wasting the operation time of the equipment, and improving the production efficiency.

[0022] On the other side of the precast cement slab, a first baffle 3 is provided. The first baffle 3 is fixedly installed on both sides of another support base 2 and cooperates with the second baffle 4 to limit the precast cement slab.

[0023] The engaging mechanism includes slots 15 evenly opened on the outer wall of the connecting block 14. The number of slots 15 can be designed according to the actual required precision. The higher the precision, the more the number of slots 15. A clamping block 16 is slidably installed on the inner wall of one of the slots 15. A sleeve 25 is provided at the top of the clamping block 16, and a second lead screw 24 is provided at the top of the sleeve 25. An instantaneous mechanism is provided between the sleeve 25 and the second lead screw 24. With such a design, when it is necessary to change the moving direction of the connecting member 12, only the clamping block 16 on the inner wall of one of the slots 15 needs to be pulled out, and at the same time, the other clamping block 16 is embedded into the inner wall of the slot 15, so as to change the moving direction of the connecting member 12.

[0024] The instantaneous mechanism includes a limiting block 27 slidably installed on the inner wall of the sleeve 25. The slidable distance of the limiting block 27 is greater than the slidable distance of the clamping block 16. The second lead screw 24 is rotatably installed at the top of the limiting block 27. A second spring 26 is sleeved on the outer wall of the limiting block 27. One end of the second spring 26 is fixedly connected to the inner wall of the sleeve 25, and the other end of the second spring 26 is fixedly connected to the top of the limiting block 27. A spherical block 33 is fixedly installed on the outer wall of the limiting block 27. One side of the spherical block 33 abuts against a blocking block 32. The blocking block 32 is slidably installed on the inner wall of the connecting member 12. A fourth spring 31 is provided between the blocking block 32 and the inner wall of the connecting member 12. With such a design, resistance can be generated to the movement of the sleeve 25, so that the second lead screw 24 will first pull or push the limiting block 27 to move when moving. When the limiting block 27 moves to a certain position, due to the spherical block 33 overcoming the resistance of the blocking block 32, the blocking block 32 is squeezed into a contracted state, so that the sleeve 25 drives the spherical block 33 to cross the blocking block 32, thereby controlling the movement of the sleeve 25, playing a role of accumulating the elastic potential energy of the second spring 26 and being able to instantaneously release the elastic potential energy when the elastic potential energy exceeds a certain value, so as to control the clamping block 16 to quickly disengage from the inner wall of the slot 15 or the clamping block 16 to quickly embed into the inner wall of the slot 15, realizing the function of quickly changing the movement direction of the connecting member 12.

[0025] The second gear 17 and the third gear 18 are both rotatably installed on the inner wall of the connecting member 12. There are two sets of the second gear 17 and the third gear 18 respectively. Two second gears 17 and third gears 18 in each set are coaxially arranged. When the first connecting plate 19 or the second connecting plate 20 meshes with the third gear 18, the rotational directions of the two third gears 18 meshed with the first connecting plate 19 or the second connecting plate 20 are opposite. Thus, one of the clamping blocks 16 is disengaged from the clamping groove 15, and the other clamping block 16 is inserted into the clamping groove 15, realizing the change of the direction of the connecting member 12.

[0026] The bottom end of the sleeve 25 is slidably installed with a clamping block 16. A third spring 28 is arranged between the clamping block 16 and the clamping groove 15. The bottom end of the clamping block 16 is arc-shaped, which can enable the clamping block 16 to be better inserted into the inner wall of the clamping groove 15, avoiding the problem that the clamping block 16 gets stuck, resulting in the connecting member 12 stopping moving and causing equipment damage, and improving the stability of the device. With such a design, when the clamping block 16 and the clamping groove 15 are not aligned, it does not affect the movement of the sleeve 25. Only after continuing to rotate, under the action of the third gear 18, the clamping block 16 will be pushed into the inner wall of the clamping groove 15. At this time, the other clamping block 16 has been disengaged from the inner wall of the clamping groove 15, so there will be no movement interference.

[0027] On the same horizontal plane, the inclination directions of the tooth blocks on the outer wall of the third gear 18 are opposite. On the same vertical plane, the inclination directions of the tooth blocks on the outer wall of the third gear 18 are opposite. The outer walls of the first connecting plate 19 and the second connecting plate 20 are both evenly provided with grooves 21. An active tooth block 22 is rotatably installed on the inner wall of the groove 21. One side of the active tooth block 22 is connected to the inner wall of the groove 21 through a first spring 23. The cross-section of the first connecting plate 19 is Z-shaped, one end of which is flush with one of the third gears 18 at the bottom end, and the other end is flush with the other third gear 18 at the top end. With such a design, in cooperation with the special shapes of the first connecting plate 19 and the second connecting plate 20, when the first connecting plate 19 or the second connecting plate 20 contacts the side wall of the third gear 18, the third gears 18 on both sides of the first connecting plate 19 or the second connecting plate 20 can always rotate in opposite directions, thus realizing the relative locking between one side of the connecting block 14 and the connecting member 12 and the relative unlocking between the other side of the connecting block 14 and the connecting member 12.

[0028] One end of the first lead screw 8 is fixedly installed with a first gear 9, and the two first gears 9 are meshed and connected. The ends of the two first lead screws 8 are rotatably installed on the side wall of the support base 2. The thread directions on the outer walls of the two first lead screws 8 are the same, which can ensure that when the driving motor 29 drives the first lead screw 8 to rotate, through the first gear 9, the rotation directions of the two first lead screws 8 are opposite. One end of one of the first lead screws 8 passes through the support base 2 and is fixedly connected to the output end of the driving motor 29. The driving motor 29 is a prior art, and the specific structure and working principle will not be elaborated in this invention. The driving motor 29 is fixedly installed on the side wall of the support base 2, and can drive the two first lead screws 8 to rotate in different directions through the rotation of the driving motor 29, providing the basic power for the movement of the connecting member 12 and the subsequent adjustment of the direction of the connecting member 12.

[0029] Working mode: When processing a precast concrete slab, the precast concrete slab can be placed on the processing equipment platform 1, and then under the action of the driving system, the precast concrete slab is pushed to move on the processing equipment platform 1. Before moving, the control rod 6 can be rotated to make the control rod 6 push the second baffle 4 to move to one side of the precast concrete slab (it is best to leave a little distance for the convenient movement of the precast concrete slab). The movement of the control rod 6 will also drive the second side plate 11 to move on the outer wall of the first lead screw 8, and then process the precast concrete slab. Start the grinding system 5 and the driving motor 29. The start of the grinding system 5 will grind the surface of the precast concrete slab. At the same time, the driving motor 29 will drive the first lead screw 8 to rotate. Since there is a first gear 9 between the two first lead screws 8, the rotation directions of the two first lead screws 8 are opposite. At this time, the driving motor 29 will drive the grinding system 5 to move horizontally to grind the surface of the precast concrete slab.

[0030] When the connecting member 12 moves to the side close to the second side plate 11, the first connecting plate 19 on the side wall of the second side plate 11 will be embedded into the inner wall of the connecting member 12 and engage with the third gear 18 in the connecting member 12, so that the movable tooth blocks 22 on the side wall of the first connecting plate 19 respectively push the third gears 18 on both sides to rotate in the reverse direction. When one of the third gears 18 rotates, it will drive the second gear 17 to rotate. The rotation of the second gear 17 will drive the second lead screw 24 to slide upward. The upward sliding of the second lead screw 24 will pull the limit block 27 to slide upward on the inner wall of the sleeve 25. At this time, the spherical block 33 will abut against the side wall of the blocking block 32. At this time, the second spring 26 will contract and accumulate elastic potential energy. When the second lead screw 24 continues to slide upward, at this time, the spherical block 33 will squeeze the blocking block 32, causing the blocking block 32 to contract, so that the spherical block 33 can cross over the blocking block 32 and drive the sleeve 25 to slide upward. At this time, the second spring 26 releases the elastic potential energy, enabling the sleeve 25 to move upward quickly, thereby driving the block 16 at the bottom of the sleeve 25 to disengage from the inner wall of the card slot 15, so that the connecting block 14 is in the unlocked state. At the same time, the reverse rotation of the other third gear 18 will drive the block 16 to be embedded into the inner wall of the card slot 15, so that the connection between the connecting member 12 and the connecting block 14 is locked, so that the rotation of the first lead screw 8 drives the connecting block 14 to rotate, thereby changing the movement direction of the connecting member 12. When the connecting member 12 moves in the reverse direction, at this time, the first connecting plate 19 disengages from the inner wall of the connecting member 12. At this time, under the extrusion of the third gear 18, the movable tooth block 22 will contract into the inner wall of the groove 21, so that it will not drive the third gear 18 to rotate. Finally, when the connecting member 12 approaches the side of the first side plate 10, the above operation is repeated to change the movement direction of the connecting member 12, so that the connecting member 12 moves back and forth between the first side plate 10 and the second side plate 11, thereby grinding the cement precast slab.

[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
