Description

Technical Field

[0001] The present invention relates to the technical field of concrete precast blocks, and specifically to a concrete precast block preparation device. Background Art

[0002] Concrete is a building material, which refers to the general term of engineering composite materials that cementitious materials bond aggregates into a whole. Usually, the term "concrete" refers to cement concrete that uses cement as the cementitious material, sand and stone as aggregates, and is mixed with water (which may contain additives and admixtures) in a certain proportion and obtained by stirring. It is widely used in civil engineering. Concrete has the characteristics of rich raw materials, low price, and simple production process, so its usage is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. Concrete precast components are building components prefabricated in a factory with concrete as the basic material, including beams, slabs, columns, and building decoration accessories, etc. The main function of precast blocks is to improve the construction speed of underground coal mine closures and cavity filling, improve production efficiency. For strata with poor self-bearing capacity, precast blocks are embedded in the trough to form a support to form a protective structure. This kind of concrete block is light in weight, good in airtight performance, and can be prefabricated into block-shaped finished products, which can be used immediately upon arrival at the site without the need to purchase special equipment, improving construction efficiency and saving costs.

[0003] The production method of concrete precast blocks is mostly to pour the prepared concrete into the mold, and then workers put the vibrating rod into the mold one by one for vibration to reduce the amount of air holes after the concrete solidifies. Then, it is necessary to cover the tops of multiple molds with plastic film. Covering a layer of plastic film is to prevent the internal cement from evaporating too fast, because the cement needs a certain amount of moisture for hydration reaction to enhance the strength of the concrete precast block. If the evaporation is too fast, it may cause surface cracking, peeling, etc., thus affecting the durability and strength of the concrete. The existing concrete precast blocks rely on manual covering of plastic film in the final stage of preparation. The manual covering speed is slow, and it is easy to have incomplete covering, resulting in low preparation efficiency of the precast blocks. Summary of the Invention

A plurality of conveying rollers are rotatably connected between the two fixed frames at equal intervals.

[0049] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0050] 1. The partition shell with multiple molds inside is placed on the U-shaped seats on two chains, so that the cylinder is sleeved with the U-shaped seat. The output end of the reduction motor can drive the first rotating shaft and two sprockets to rotate, so as to drive the two chains and the other two sprockets to move. Thus, the moving U-shaped seats can drive a plurality of partition shells to move horizontally. The conveying mechanism can drive a plurality of molds to complete the work of pouring concrete, vibrating concrete, scraping and recycling materials, and finally film covering and curing when moving forward. Moreover, each partition shell can be conveyed simultaneously, so as to improve the preparation efficiency of concrete precast blocks through the automatic moving preparation method. After the external pouring equipment pours concrete into the four molds in the partition shell, the conveying mechanism can move the partition shell to the top of the rotating disc. Then, the output end of the first driving motor drives the synchronous pulley to rotate. Under the action of the transmission belt, the two rotating rollers can be driven to rotate simultaneously. Then, the multiple rotating discs on the outer walls of the rotating rollers can drive a plurality of driving rods to rotate simultaneously. Thus, the rubber balls at the ends of the plurality of driving rods can knock and vibrate the bottom of the molds. Since buffer springs are arranged on both sides of the molds, the molds can slide up and down and vibrate in the partition shell. This can improve the compactness of the concrete, reduce the pores and cracks after the precast blocks are formed, thus improving the strength of the concrete precast blocks. It can also reduce the quality defects such as honeycombing and pockmarks on the concrete surface and improve the appearance quality of the precast blocks.

[0051] 2. The output end of the servo motor in the scraper mechanism drives the bidirectional screw to rotate, thereby driving the two mobile shovels to move relative to each other, and the bottom end of the mobile shovel slides with the top of the partition shell. At this time, the mobile shovel is located between the two side plates of the partition shell. The mobile shovel can scrape the excess concrete overflowing from the top of the mold, and the excess concrete will be scraped into the discharge chute. Since the discharge chute is located at the top of the support cavity shell, the excess concrete will fall into the opening at the top of the support cavity shell, and then flow into the recovery cylinder through the inclined surface of the support cavity shell. The second output end of the drive motor drives the auger to rotate, so that the concrete can be transported and discharged for recycling, so that the production materials can be quickly recovered through the scraper mechanism and the recovery mechanism, which is beneficial to environmentally friendly production and saves production costs.

[0052] 3. The connecting pipe can be evacuated by a suction pump, and the connecting pipe is connected to the hollow frame. When the four suction cups press the plastic film on the placement plate, the suction pump is used to evacuate air to generate negative pressure, thereby lifting the plastic film and pressing it down to the top of the partition shell. Then, air is supplied into the frame by the suction pump, so that the four suction cups spray out air, which can make the plastic film adhere to the two side walls of the partition shell along the length direction. When the frame descends, the four abutting rods will be driven to descend and abut the ends of the folding surface clamps, so that the two folding surface clamps rotate in opposite directions, so that the two ends of the plastic film along the length direction can be clamped by the folding surface clamps, so that multiple molds can be covered to prevent the concrete moisture from evaporating too quickly, which is helpful to improve the strength and durability of the concrete precast blocks, and the coverage is relatively complete, and does not need to rely on manual covering, so that the prepared concrete precast blocks are automatically maintained, thereby improving the construction efficiency of the concrete precast blocks.

Detailed implementation manners

[0063] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0064] Please refer to Figures 1-9 In an embodiment of the present invention, a concrete precast block manufacturing device includes: The conveying mechanism 100 includes two support plates 101 for conveying the concrete precast block forming tool; The film clamping mechanisms 200 are equidistantly arranged on the conveying mechanism 100 for clamping the plastic film; The recycling mechanism 300 is arranged between the conveying mechanisms 100 for recycling and utilizing the excess concrete; The scraping mechanism 400 is arranged on the top of the conveying mechanism 100 for scraping and removing the excess concrete during pouring.

[0065] The conveying mechanism 100 includes: There are two rotating shafts 102, rotatably connected between the two ends of the two support plates 101; There are four sprockets 103, all fixedly sleeved on the ends of the rotating shaft 102; There are two chains 104, meshing and sleeved between the two sprockets 103; There are multiple U-shaped seats 105, fixedly connected to the chain 104 at equal distances; The output end of the reduction motor 106 is fixedly connected to the end of the rotating shaft 102. There are two rotating rollers 107; There are two synchronous belt pulleys 108, all fixedly sleeved on the ends of the rotating rollers 107; The transmission belt 109 is sleeved between the two synchronous belt pulleys 108; The output end of the driving motor 1 is fixedly connected to the end of the rotating roller 107; The rotating disks 111 are fixedly sleeved on the outer walls of the rotating rollers 107 at equal distances; There are multiple driving rods 112, annularly and fixedly connected to the outer walls of the rotating disks 111 at equal distances; There are multiple rubber balls 113, all movably connected to the ends of the driving rods 112; The film clamping mechanism 200 includes: The partition shells 201 are arranged between the two chains 104 at equal distances; The discharge grooves 202 are opened in the partition shells 201 at equal distances; There are two cylinders 203, symmetrically and fixedly connected to the center positions of the ends of the partition shells 201, and the cylinders 203 are slidably clamped with the U-shaped seats 105; There are four damping rotating shafts 204, symmetrically rotatably connected to the opposite side walls of the partition shells 201; There are two folding surface clamping plates 205, both rotatably connected between the two damping rotating shafts 204; The elastic layer 206 is fixedly arranged on the side wall of the folding surface clamping plate 205. Multiple molds 207 are slidably and embeddedly connected in the partition shells 201 at equal distances, and two buffer springs 208 are symmetrically and fixedly connected to the molds 207, and the ends of the buffer springs 208 are fixedly connected to the inside of the partition shells 201.

[0066] Specifically, place the partition shell 201 with multiple molds 207 inside on the U-shaped seats 105 on the two chains 104, so that the cylinders 203 and the U-shaped seats 105 are sleeved. The output end of the reduction motor 106 can drive the rotating shaft 102 and the two sprockets 103 to rotate, so as to drive the two chains 104 and the other two sprockets 103 to move. Thus, the moving U-shaped seats 105 can drive multiple partition shells 201 to translate. The conveying mechanism 100 can drive multiple molds 207 to complete the work of pouring concrete, vibrating concrete, scraping and recycling materials, and finally film covering and curing when moving forward. Moreover, each partition shell 201 can be conveyed simultaneously, so as to improve the preparation efficiency of concrete precast blocks through the way of automated moving preparation;

[0067] After the four molds 207 in the partition shell 201 are poured with concrete by an external pouring device, the conveying mechanism 100 can move the partition shell 201 to the top of the rotating disk 111, and then drive the synchronous pulley 108 to rotate through the output end of the first driving motor 110. Under the action of the transmission belt 109, the two rotating rollers 107 can be driven to rotate simultaneously. Then, the multiple rotating disks 111 on the outer walls of the rotating rollers 107 can drive the multiple driving rods 112 to rotate simultaneously. Thus, the rubber balls 113 at the ends of the multiple driving rods 112 can knock and oscillate the bottom of the mold 207. Since the buffer springs 208 are arranged on both sides of the mold 207, the mold 207 can slide up and down and oscillate in the partition shell 201. This can improve the compactness of the concrete, reduce the pores and cracks in the precast block after molding, thereby enhancing the strength of the concrete precast block. It can also reduce the quality defects such as honeycombing and pitting on the surface of the concrete and improve the appearance quality of the precast block.

The scraping mechanism 400 includes: two moving shovel plates 404 are provided, which are slidably connected to the top of the partition shell 201; a bidirectional lead screw 403 is screwed between the two moving shovel plates 404; the output end of a servo motor 405 is fixedly connected to the end of the bidirectional lead screw 403.

[0070] In this embodiment, the output end of the servo motor 405 in the scraping mechanism 400 drives the bidirectional lead screw 403 to rotate, so as to drive the two moving shovel plates 404 to move relative to each other. The bottom end of the moving shovel plate 404 slides on the top of the partition shell 201. At this time, the moving shovel plate 404 is located between the two side plates of the partition shell 201. The excess concrete on the top of the overflow mold 207 can be scraped flat by the moving shovel plate 404, and the excess concrete will be scraped off into the discharge chute 202. Since the discharge chute 202 is located on the top of the support cavity shell 301, the excess concrete will fall into the opening at the top of the support cavity shell 301, and then flow into the recovery cylinder 302 through the inclined surface of the support cavity shell 301. The output end of the driving motor two 303 drives the auger 304 to rotate, so as to convey and discharge the concrete for recovery. Therefore, the production materials can be quickly recovered through the scraping mechanism 400 and the recovery mechanism 300, which is beneficial to environmental protection production and saves production costs.

[0071] Embodiment Two

[0072] As Figure 9 shown, in this embodiment, the film covering mechanism 500 is used to cover the plastic film on the top of the concrete precast block forming appliance; the film covering mechanism 500 includes a cylinder one 501, the end of the cylinder one 501 is fixedly connected with a moving plate 502, the bottom of the moving plate 502 is fixedly connected with two cylinders two 503, a frame body 504 is fixedly connected between the bottom ends of the two cylinders two 503, four suction cups 507 communicating with the inside thereof are symmetrically fixedly connected to the bottom of the frame body 504 about its vertical center plane, a communicating pipe 505 is fixedly connected to the top of the frame body 504, and a suction pump 506 is fixedly arranged at the center position of the top of the communicating pipe 505; two abutting rods 508 are symmetrically fixedly connected to the opposite side walls of the frame body 504, and the end of the abutting rod 508 abuts against the end of the folding surface clamping plate 205; a placing plate 510 is arranged on one side of the frame body 504, a plastic film is carried on the placing plate 510, fixing frames 509 are fixedly connected to both ends of the placing plate 510, and a plurality of conveying rollers 511 are rotatably connected between the two fixing frames 509 at equal intervals.

The suction pump 506 can evacuate the connecting pipe 505. The connecting pipe 505 is connected to the hollow frame body 504. Thus, when the four suction cups 507 press on the plastic film on the placing plate 510, the suction pump 506 evacuates the air to generate negative pressure, so that the plastic film can be lifted and pressed down to the top of the separation shell 201. Then, the suction pump 506 supplies air into the frame body 504, causing the four suction cups 507 to eject air, so that the plastic film can adhere to the two side walls of the separation shell 201 along the length direction. When the frame body 504 descends, it will drive the four abutting rods 508 to descend and abut against the ends of the folding surface clamping plates 205, so that the two folding surface clamping plates 205 rotate in opposite directions, and the two ends of the plastic film along the length direction can be clamped by the folding surface clamping plates 205, so as to cover a plurality of molds 207, prevent the concrete moisture from evaporating too fast, help improve the strength and durability of the concrete precast blocks, have a higher covering integrity, do not need to rely on manual covering, and automatically cure the prepared concrete precast blocks, so that the construction efficiency of the concrete precast blocks can be improved.
