Description

Technical Field

[0001] This invention relates to the field of concrete processing technology, specifically to a multi-frame concrete processing equipment for bridge construction. Background Technology

[0002] In bridge construction, concrete, as a core load-bearing structural material (such as beams, piers, and bridge deck pavement), directly determines the bridge's load-bearing capacity and service life due to its homogeneity, strength stability, and durability. Bridge construction places far higher demands on concrete performance than ordinary building construction: on the one hand, bridge structures are subjected to long-term dynamic loads (vehicle impact) and environmental loads (temperature differences, wind and rain erosion, freeze-thaw cycles), requiring concrete to possess precise strength grades (typically C50 and above high-strength concrete), extremely low air content, and excellent impermeability; on the other hand, bridge components are often large-volume, irregularly shaped structures (such as continuous beams and rigid frame box girders), requiring uniform material flowability during concrete pouring to avoid quality defects such as cracks and honeycomb surfaces caused by localized mix imbalances.

[0003] According to Chinese Patent Publication No. CN111015958A, a multi-frame concrete processing equipment for bridge construction is disclosed. Its structure includes a material guiding mechanism, a conveyor frame, a power supply box, rolling wheels, support legs, a base, and a mixing tank. The material guiding mechanism is mounted on the conveyor frame via a movable connection. This invention utilizes a silent guide trough mechanism to pour material from the feed hole into the support cover. The sand and gravel in the material will impact the arc-shaped guide frame, which buffers the sand and gravel, preventing direct contact between the sand and gravel and the inner wall of the support cover, thus significantly reducing noise. When the buffer base plate is filled with sand and gravel, the buffer base plate will move the inner support plate downwards, compressing the buffer. When the weight reaches a set value, the electric contact column will contact the electric contact point, providing power to the connector and illuminating the warning light on the connector. This effectively prevents the equipment from operating under heavy load, thus preventing abnormal noise.

[0004] The aforementioned patent provides equipment stability through a buffer during use, but the stirring rod can only rotate and stir the material within a fixed range. Therefore, there will be dead zones in the tank, which will affect the mixing effect of the material. Hence, a multi-frame concrete processing equipment for bridge construction is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a multi-frame concrete processing equipment for bridge construction, which addresses the shortcomings of the prior art.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is: a multi-frame concrete processing equipment for bridge construction, including a base, a mixing tank arranged on the top of the base, a support leg connected to the side of the mixing tank, the support leg being connected to the top of the base, and a mixing mechanism arranged inside the mixing tank.

[0007] The stirring mechanism includes a motor, a drive shaft, a first bracket, a first stirring rod, a first movable rod, a vertical shaft, a second stirring rod, a first vertical rod, a first gear, and a second gear;

[0008] The motor is connected to the bottom of the mixing tank, the top output end of the motor passes through the mixing tank and is connected to the bottom end of the drive shaft, the first bracket is connected to the mixing tank, the top end of the drive shaft rotates through the first bracket via a bearing, and the first stirring rod is connected to the drive shaft.

[0009] Preferably, one end of the first movable rod is connected to the drive shaft, the top end of the vertical shaft rotates through the first movable rod via a bearing, the second stirring rod is connected to the vertical shaft, and the first stirring rod and the second stirring rod are arranged alternately.

[0010] Preferably, the first vertical rod is connected to the right side of the first bracket, the bottom end of the first vertical rod is connected to the first gear, the top end of the transmission shaft rotates through the first gear via a bearing, the second gear is connected to the top end of the vertical shaft, and the first gear is connected to the second gear.

[0011] Preferably, the top of the mixing tank is provided with a water spraying mechanism, which includes a second bracket connected to both sides of the mixing tank. A slide rod is slidably passed through one side of the second bracket via a linear bearing, and a water jug ​​is connected to the top of the slide rod.

[0012] Preferably, a crossbar is connected to the side of the kettle, and a water pipe is provided inside the crossbar. One end of the water pipe extends into the interior of the kettle, and the other end of the water pipe away from the kettle is connected to a nozzle, which is connected to the crossbar.

[0013] Preferably, a first sliding groove is connected to the middle of the sliding rod, a first slider is slidably connected inside the first sliding groove, a second movable rod is connected to the top of the drive shaft, and the other end of the second movable rod away from the drive shaft is connected to the bottom of the first slider.

[0014] Preferably, the mixing tank has a discharge port on the right side, and a discharge pipe is connected to the discharge port. The discharge pipe has a clearing mechanism inside, which includes a vertical groove that extends through the top of the discharge pipe.

[0015] Preferably, the left and right sides of the vertical groove are internally connected to first limiting blocks, and a first limiting groove is formed on the opposite side of the two first limiting blocks. A second limiting block is slidably connected inside the first limiting groove, and a second limiting groove is formed on the opposite side of the two second limiting blocks. A third limiting block is connected inside the second limiting groove.

[0016] Preferably, a second vertical rod is connected between the two third limiting blocks. The top end of the second vertical rod is connected to the right end of the sliding rod, and the bottom end of the second vertical rod is connected to an annular shovel plate. The annular shovel plate is disposed inside the discharge pipe, and the outer wall of the annular shovel plate is in contact with the inner wall of the discharge pipe.

[0017] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0018] 1. This invention achieves the effect of thorough mixing of materials in the mixing tank by setting up a mixing mechanism. The motor drives the transmission shaft to rotate the first mixing rod, and at the same time, the first movable rod drives the vertical shaft and the second mixing rod to rotate around the mixing tank. With the help of the meshing of the first gear and the second gear, the second mixing rod rotates synchronously on its own axis while revolving. The first and second mixing rods are staggered and cover the entire area inside the tank, which further improves the homogeneity of the concrete materials, meets the homogeneity requirements of high-strength concrete in bridge construction, and avoids the strength fluctuation problem caused by uneven mixing.

[0019] 2. This invention achieves the effect of uniformly injecting water into the mixing tank by setting up a water spraying mechanism. The drive shaft drives the second movable rod and the first slider to move back and forth, so that the water jug ​​moves synchronously through the crossbar and the nozzle, spraying water evenly to different areas in the tank. This works in conjunction with the full-range mixing of the mixing mechanism, allowing the water to quickly and fully mix with materials such as cement and aggregates, further improving the workability of the concrete mixture and avoiding uneven local drying and wetting, which would affect the quality of subsequent bridge component pouring.

[0020] 3. This invention achieves the effect of preventing blockage of the discharge pipe by setting up a dredging mechanism. When the sliding rod moves left and right, it drives the second vertical rod and the annular shovel to move back and forth synchronously. The annular shovel scrapes off the attached concrete residue by adhering to the inner wall of the discharge pipe. At the same time, the cooperation of the first limit block, the second limit block and the third limit block keeps the vertical channel blocked to prevent material leakage. It forms a linkage with the mixing mechanism and the water spraying mechanism to ensure that the mixed concrete is discharged smoothly, further improving the overall construction efficiency of the equipment and avoiding delays in bridge construction progress due to material blockage.

[0029] 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.

[0030] Please see Figure 1-7 One embodiment of the present invention is: a multi-frame concrete processing equipment for bridge construction, including a base 1, a mixing tank 3 is arranged above the base 1, a support leg 2 is connected to the side of the mixing tank 3, the support leg 2 is connected to the top of the base 1, and a mixing mechanism 5 is arranged inside the mixing tank 3.

[0031] The stirring mechanism 5 includes a motor 501, a transmission shaft 502, a first bracket 503, a first stirring rod 504, a first movable rod 505, a vertical shaft 506, a second stirring rod 507, a first vertical rod 508, a first gear 509, and a second gear 5010.

[0032] Motor 501 is connected to the bottom of mixing tank 3. The top output end of motor 501 passes through mixing tank 3 and is connected to the bottom end of drive shaft 502. First bracket 503 is connected to mixing tank 3. The top end of drive shaft 502 rotates through first bracket 503 via bearing. First stirring rod 504 is connected to drive shaft 502.

[0033] One end of the first movable rod 505 is connected to the drive shaft 502. The top end of the vertical shaft 506 rotates through the first movable rod 505 via a bearing. The second stirring rod 507 is connected to the vertical shaft 506. The first stirring rod 504 and the second stirring rod 507 are arranged alternately.

[0034] The first vertical rod 508 is connected to the right side of the first bracket 503. The bottom end of the first vertical rod 508 is connected to the first gear 509. The top end of the transmission shaft 502 rotates through the first gear 509 via a bearing. The second gear 5010 is connected to the top end of the vertical shaft 506. The first gear 509 is connected to the second gear 5010.

[0035] Working Principle: First, the cement, sand, and gravel to be mixed are poured into the mixing tank 3. Then, the motor 501 is turned on, driving the drive shaft 502 to rotate. The rotation of the drive shaft 502 drives the first stirring rod 504 to rotate, thus stirring the materials in the mixing tank 3. Simultaneously, the rotation of the drive shaft 502 drives the first movable rod 505 to rotate. The rotation of the first movable rod 505 drives the vertical shaft 506 to rotate around the inside of the mixing tank 3. Simultaneously, the rotation of the vertical shaft 506 drives the second stirring rod 507 to rotate around the inside of the mixing tank 3, thereby further improving the mixing effect. The rotation of the vertical shaft 506 around the inside of the mixing tank 3 drives the second gear 5010 to rotate around the inside of the mixing tank 3. Furthermore, under the action of the first gear 509, the second gear 5010, the vertical shaft 506, and the second stirring rod 507 rotate on their own axes. Thus, the second stirring rod 507 rotates both around the inside of the mixing tank 3 and on its own axis, further enhancing the mixing effect.

[0036] Please see Figure 1-7 Based on the above embodiments, in another embodiment of the present invention, a water spraying mechanism 6 is provided at the top of the mixing tank 3. The water spraying mechanism 6 includes a second bracket 601, which is connected to both sides of the mixing tank 3. A slide rod 602 is slidably passed through one side of the second bracket 601 via a linear bearing, and a water jug ​​606 is connected to the top of the slide rod 602.

[0037] A crossbar 607 is connected to the side of the kettle 606. A water pipe is installed inside the crossbar 607. One end of the water pipe passes through the inside of the kettle 606, and the other end of the water pipe away from the kettle 606 is connected to a nozzle 608. The nozzle 608 is connected to the crossbar 607.

[0038] The middle part of the slide bar 602 is connected to the first slide groove 603, and the first slide block 604 is slidably connected inside the first slide groove 603. The top end of the drive shaft 502 is connected to the second movable rod 605, and the other end of the second movable rod 605 away from the drive shaft 502 is connected to the bottom of the first slide block 604.

[0039] Working principle: The rotation of the drive shaft 502 drives the second movable rod 605 to rotate. The rotation of the second movable rod 605 drives the first slider 604 to rotate around the drive shaft 502. The rotation of the first slider 604 around the drive shaft 502 drives the slide rod 602 to move left and right through the first slide groove 603. The left and right movement of the slide rod 602 drives the water jug ​​606 to move left and right. The left and right movement of the water jug ​​606 drives the crossbar 607 and the nozzle 608 to move left and right, while water is evenly injected into the mixing tank 3, so that the water and materials are more fully mixed.

[0040] Please see Figure 1-7 Based on the above embodiments, in another embodiment of the present invention, a discharge port is provided on the right side of the mixing tank 3, and a discharge pipe 4 is connected to the discharge port. A clearing mechanism 7 is provided inside the discharge pipe 4. The clearing mechanism 7 includes a vertical groove 706, which is opened through the top of the discharge pipe 4.

[0041] The left and right sides of the vertical groove 706 are internally connected to the first limiting block 701. The two first limiting blocks 701 are provided with a first limiting groove on the opposite side. The first limiting groove is slidably connected to the inside of the first limiting groove. The two second limiting blocks 702 are provided with a second limiting groove on the opposite side. The second limiting groove is internally connected to the third limiting block 703.

[0042] A second vertical rod 704 is connected between the two third limiting blocks 703. The top end of the second vertical rod 704 is connected to the right end of the slide rod 602. The bottom end of the second vertical rod 704 is connected to an annular shovel 705. The annular shovel 705 is located inside the discharge pipe 4, and the outer wall of the annular shovel 705 is in contact with the inner wall of the discharge pipe 4.

[0043] Working principle: As the sliding rod 602 moves left and right, it drives the second vertical rod 704 to move left and right. Simultaneously, the second vertical rod 704 drives the third limiting block 703 to move left and right. The third limiting block 703 moves within the second limiting groove, driving the second limiting block 702 to move left and right. The second limiting block 702 then inserts into the first limiting groove, thus continuously sealing the vertical groove 706 through the first limiting block 701, the second limiting block 702, and the third limiting block 703. Simultaneously, the left and right movement of the second vertical rod 704 drives the annular scraper 705 to move left and right. The annular scraper 705 scrapes off impurities adhering to the inner wall of the discharge pipe 4, thereby preventing blockage.
