Abstract

This invention discloses a rod-pulling device for the production of energy-saving aerated concrete panels, relating to the field of aerated concrete panel production technology. It includes: two mounting frames, with a mold positioned between the two frames, and a crossbeam connected between the two molds via a lifting assembly; multiple rods are mounted on the crossbeam via multiple sets of rotating components, each rotating component including a worm gear rotatably connected to the top surface of the crossbeam. The rotating components and a dust-collecting assembly work together to create a sealing rod, a spring, and a dust-collecting hole on the rod. When the rod is inserted into the concrete, it is pushed upwards by the slurry pressure, compressing the spring and causing the sealing rod to block the dust-collecting hole, achieving zero seepage of liquid concrete into the ventilation opening. When the rod rises, the spring resets, and the dust-collecting hole opens. A fan forms a negative pressure channel through a connecting pipe, a rotating column, a fixed column, and a sealing rod, directly adsorbing dust from the rod-pulling hole source, which is then filtered by a treatment box before being discharged as clean air.

Description

Technical Field

[0001] This invention relates to the field of aerated concrete panel production technology, specifically to a pull-out device for the production of energy-saving aerated concrete panels. Background Technology

[0002] To ensure the strength of aerated concrete panels and facilitate transportation and installation, a steel mesh cage needs to be embedded during the manufacturing process. The steel rods of the steel mesh cage hanger carry the cage into the fermenting liquid concrete within the mold. After sufficient fermentation time, the steel rods and the cage need to be separated; this separation process is called rod removal.

[0003] A search revealed a Chinese patent with publication number CN109368507B, which discloses an aerated concrete inserting and pulling rod hoist and its mobile rod-rotating device. In this hoist, a saddle is used to fix the steel rod, suspending the rebar mesh cage inside the mold cart via the rod; a saddle base supports multiple saddles; a mobile rod-rotating device drives the steel rod to rotate, locking or unlocking the rod and rebar mesh cage; a rod-rotating hanger supports the movement of the mobile rod-rotating device and can lock or unlock the saddle base; a lifting and traveling device lifts or lowers the rod-rotating hanger and can move the entire equipment. This invention simplifies the inserting and pulling rod process, automates the insertion and pulling of rebar mesh cages, adapts to diverse plate specifications, and automatically moves the rod-rotating device, greatly improving production efficiency.

[0004] However, in the existing technology, it is impossible to drive all steel rods to rotate and loosen simultaneously while the crossbeam is being raised and lowered through pure mechanical linkage. This results in high resistance to rod removal, the need for additional motors or hydraulic swing mechanisms, high energy consumption, and large synchronization errors. Furthermore, it is impossible to seal the dust suction hole immediately when the steel rod is inserted into the liquid concrete, causing slurry to seep into the ventilation channel and block the pipeline. In addition, the dust from the rod loosening is directly sucked in from the source at the moment of rod removal, resulting in the dust concentration on site exceeding the limit and requiring manual secondary cleaning of the hole.

[0005] Therefore, based on the above-mentioned search and combined with existing technologies, a pull-out device for the production of energy-saving aerated concrete panels is proposed to solve the above problems. Summary of the Invention

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In this invention, by setting up a rotating component and a dust-collecting component, the dust-collecting holes of the sealing rod, spring, and steel rod cooperate with each other. When the steel rod is inserted into the concrete, it is pushed upward by the pressure of the slurry, compressing the spring and causing the sealing rod to block the dust-collecting hole, thus achieving zero seepage of liquid concrete into the ventilation opening. When the steel rod rises, the spring returns to its original position, and the dust-collecting hole opens.

After being filtered by the treatment box, clean air is discharged.

[0018] 2. In this invention, by setting up a lifting component and a driving component, the toothed belt, gear, synchronous belt II, worm, and worm wheel cooperate with each other. When the crossbeam rises, the fixed gear meshes with the toothed belt on the side wall of the mounting frame, driving the rotating column to rotate. The worm rotates through the coupling II and the synchronous belt II, and the worm wheel transmits the torque to the fixed column. The steel rod rotates synchronously, directly using the lifting kinetic energy to drive the rotating rod action, eliminating the need for an additional motor. Moreover, the self-locking characteristics of the worm wheel and worm gear ensure accurate rotation angle. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] In one typical implementation of this application, please refer to Figures 1 to 8 As shown, a rod-pulling device for producing energy-saving aerated concrete panels includes: a mounting frame 1, two mounting frames 1 are provided, a mold 2 is provided between the two mounting frames 1, and a crossbeam 3 is provided between the two molds 2 via a lifting assembly;

[0030] Multiple steel rods 4 are mounted on the crossbeam 3 via multiple sets of rotating components. The rotating components include:

[0031] Worm gear 5 is rotatably connected to the top surface of crossbeam 3. Rotating column 6 is rotatably connected to the top surface of worm gear 5. Fixed column 7 is fixedly installed on the bottom surface of worm gear 5. Fixed column 7 extends through the top surface of crossbeam 3 to the bottom of crossbeam 3. Connecting plate 8 is fixedly installed on the outer surface of fixed column 7.

[0032] The drive assembly is used to drive multiple steel rods 4 to rotate;

[0033] A vacuuming assembly is mounted on mounting bracket 1.

[0034] As a preferred embodiment of this example, please refer to [link / reference]. Figure 4 and Figure 5As shown, the rotating assembly also includes: a sealing rod 9, the top surface of the sealing rod 9 is fixedly connected to the bottom surface of the fixed column 7, a steel rod 4 is slidably installed on the outer surface of the sealing rod 9, a spring 10 is provided between the bottom surface of the connecting plate 8 and the top surface of the steel rod 4, and a plurality of dust suction holes 11 are provided on the outer surface of the steel rod 4.

[0035] As a preferred embodiment of this example, please refer to [link / reference]. Figure 2 , Figure 3 and Figure 8 As shown, the drive assembly includes: four worm gears 12, each rotatably connected to the top surface of the crossbeam 3. Each worm gear 12 meshes with multiple worm wheels 5. A coupling 13 is fixedly mounted on the side wall of each of the four worm gears 12. Two synchronous belts 14 are arranged between the four couplings 13. A mounting groove 15 is provided on the top surface of the crossbeam 3. The drive assembly also includes: a gear 16, rotatably connected to the side wall of the mounting groove 15. A toothed belt 17 is fixedly mounted on the side wall of one mounting bracket 1 facing the mounting groove 15, meshing with the gear 16. A rotating column 18 is fixedly connected to the side wall of the gear 16. Couplings 29 are provided on the side walls of the two couplings 13 near the rotating column 18 and the side wall of the rotating column 18. A synchronous belt 20 is arranged between the three couplings 29.

[0036] Through the above features, multiple steel rods 4 can be rotated, making it convenient for the steel rods 4 to be pulled out of the mold 2, thereby saving the power required to pull the steel rods 4 out of the mold 2. In this process, the holes generated when the steel rods 4 are pulled out can be polished and the dust can be collected. Specifically, the operator raises the lifting component through the controller. During the process of the lifting component rising, the crossbeam 3 rises synchronously. During this process, the gear 16 meshes with the toothed belt 17, causing the gear 16 to rotate. When the gear 16 rotates, the coupling 19 connected to the gear 16 rotates synchronously through the synchronous belt 20, causing the other two synchronous belts 20 to rotate synchronously. The two couplings 13 near the rotating column 18 rotate through the synchronous belt 14, causing the other two couplings 13 to rotate, causing the four worm gears 12 to rotate synchronously. When the four worm gears 12 rotate, multiple worm wheels 5 rotate synchronously, causing the fixed column 7, connecting plate 8, sealing rod 9 connected to the worm wheel 5 to rotate synchronously with the steel rods 4.

[0037] Furthermore, when the lifting assembly descends and inserts multiple steel rods 4 into the mold 2, the steel rods 4 will compress the spring 10 when they come into contact with the concrete slab in the mold 2. This causes the spring 10 to deform under force, and the outer surface of the sealing rod 9 will seal the dust suction hole 11 on the steel rod 4, preventing the concrete in liquid slurry from entering the interior of the steel rod 4 through the dust suction hole 11.

[0038] As a preferred embodiment of this example, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, the dust collection assembly includes: a connecting pipe 21, which is connected to the top surface of multiple rotating columns 6. The rotating columns 6, fixed columns 7, and sealing rods 9 are connected. The bottom surface of the sealing rods 9 is a through groove. A fan 23 is fixedly installed on the top surface of one of the mounting brackets 1. An L-shaped pipe 22 is provided between the fan 23 and the connecting pipe 21. The dust collection assembly also includes: a processing box 24, which is fixedly installed on the side wall of one of the mounting brackets 1. A connecting pipe 25 is provided between the processing box 24 and the fan 23. A collection groove 26 is opened inside the processing box 24. A filter plate 27 is fixedly installed on the inner wall of the collection groove 26. Multiple air outlets 28 are opened on the side wall of the processing box 24.

[0039] Based on the above features, the dust generated when the steel rod 4 rotates can be collected and treated. Specifically, when the lifting component drives the steel rod 4 to rise, the operator turns on the fan 23. When the fan 23 is turned on, a negative pressure is generated inside the steel rod 4. The dust will enter the interior of the steel rod 4 through the dust suction hole 11, and then pass through the sealing rod 9, the fixed column 7, the rotating column 6 and the interior of the connecting pipe 21 in sequence, and enter the treatment box 24 through the L-shaped pipe 22 and the connecting pipe 25 for collection. The filter plate 27 blocks the dust, and the support frame 29 is used to let the filtered air flow out.

[0040] As a preferred embodiment of this example, please refer to [link / reference]. Figure 1 and Figure 6 As shown, the lifting assembly includes: a support frame 29, which is fixedly mounted on the top surface of two mounting brackets 1. A fixing block 30 is fixedly mounted on the side wall of the support frame 29. A sliding groove 31 is formed on the side wall of the fixing block 30. A threaded rod 32 is rotatably connected to the inner wall of the sliding groove 31. A sliding block 33 is rotatably mounted on the outer surface of the threaded rod 32. A connecting block 34 is fixedly connected to the side wall of the sliding block 33. The lifting assembly also includes: a drive motor 35, which is fixedly mounted on the top surface of the fixing block 30. The output shaft of the drive motor 35 is connected to the top surface of the threaded rod 32. The bottom surface of the connecting block 34 is fixedly connected to the top surface of the crossbeam 3.

[0041] Through the above features, the crossbeam 3 can be raised and lowered. Specifically, when the crossbeam 3 needs to be lowered, the operator uses the controller to make the drive motor 35 rotate in the forward direction, so that the threaded rod 32 connected to the output shaft of the drive motor 35 rotates synchronously, driving the sliding block 33 and the connecting block 34 to move down. When the connecting block 34 moves down, the crossbeam 3 moves down synchronously. Conversely, when the crossbeam 3 needs to be raised, the drive motor 35 can be rotated in the direction of the movement.

[0042] Working principle:

[0043] In use, the drive motor 35 is started, which drives the threaded rod 32 to rotate, causing the sliding block 33 to rise or fall along the sliding groove 31. This, in turn, drives the crossbeam 3 to rise and fall synchronously via the connecting block 34. During the rise of the crossbeam 3, the gear 16 meshes with the toothed belt 17 fixedly installed on the side wall of the mounting frame 1, driving the rotating column 18 to rotate. The rotating column 18 drives the four worm gears 12 to rotate synchronously via the coupling 19 and the synchronous belt 20. The four worm gears 12 maintain the same speed with the coupling 13 via the synchronous belt 14, thereby driving all the worm wheels 5 to rotate in the same direction. When the worm wheels 5 rotate, the fixed column 7, the connecting plate 8, and the sealing rod 9 fixed to their bottom surface rotate synchronously, and the steel rod 4 rotates accordingly, thus loosening the steel mesh cage. Insertion stage of steel rod 4: When the crossbeam 3 descends, the steel rod 4 contacts the liquid concrete. The upward thrust of the slurry causes the steel rod 4 to move upward relative to the sealing rod 9, compressing the spring 10. The outer wall of the sealing rod 9 tightly seals the dust suction hole 11 on the surface of the steel rod 4, preventing concrete from seeping in. Removal stage of steel rod 4: When the crossbeam 3 rises, the thrust of the slurry disappears, the spring 10 returns to its original position, and the dust suction hole 11 opens. The fan 23 starts, and the negative pressure is transmitted through the L-shaped pipe 22, connecting pipe 21, rotating column 6, fixed column 7, and the internal channel of the sealing rod 9 to the dust suction hole 11, directly sucking in the dust from the removal of the rod. The dust enters the treatment box 24 through the connecting pipe 25, and after being filtered by the filter plate 27, the clean air is discharged from the air outlet 28. Throughout the process, the rotation, sealing, and dust suction of the steel rod 4 are all completed by a single power source of the lifting and lowering of the crossbeam 3, without the need for additional motors or pneumatic components, achieving energy saving, dust reduction, and continuous operation.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
