Description

Technical Field

[0001] The present invention relates to the technical field of nuclear power engineering construction, and particularly relates to a concrete conveying device for building construction and a conveying method thereof. Background Technique

[0002] Nuclear power engineering refers to a large-scale comprehensive project that uses a nuclear reactor as the core and generates electricity by using the energy released by nuclear fission or nuclear fusion. It mainly includes buildings such as workshops, pump houses, and boiler houses. The concrete raw materials used in the construction of nuclear power engineering are usually transported by a conveying device.

[0003] Existing conveying devices use various methods to achieve the conveying of concrete. For example, a concrete conveying device for building construction with the publication number CN218406542U includes a base. The upper surface of the base is movably connected with a mounting plate, and the upper surface of the mounting plate is hinged with a conveying main body. An adjusting component is arranged between the mounting plate and the conveying main body, and a clamping component is arranged between the base and the mounting plate. The adjusting component includes a fixed seat fixedly installed on the upper surface of the mounting plate. A double-shaft motor is movably connected inside the fixed seat, and a support rod is fixedly connected to the outside of the output shaft of the double-shaft motor; The conveying tanks used in existing conveying devices are usually inclined and the angle cannot be adjusted. When discharging the concrete during conveying, some concrete will accumulate at the inclined bottom of the conveying tank, resulting in incomplete discharging. And for some conveying tanks that can be adjusted in angle, they cannot completely push and discharge the concrete inside the tank body. The concrete will adhere and accumulate on the inner wall of the tank body, and the output discharging is not thorough enough; For example, in the above-mentioned referenced prior art, this device uses a double-shaft motor to drive the single-side rotation of the tank body for angle adjustment. Since the overall weight of the tank body is relatively large after being fully loaded with concrete, it is difficult to adjust the angle. And after single-side rotation, it cannot be stably supported. At the same time, this device can only perform angle adjustment and cannot achieve the rotation of the tank body, so that the tank body cannot be rotated and stirred during the conveying process, and the concrete inside it is prone to hardening and segregation. At the same time, this device only uses the spiral pushing method and cannot completely convey and discharge the concrete inside the tank body. There will still be some concrete accumulated inside the tank body after conveying; Therefore, it is urgent to design a concrete conveying device for building construction and a conveying method thereof to solve the above problems.

Detailed implementation method

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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.

[0024] Embodiment 1: Refer to Figures 1 - 2 , a concrete conveying device for building construction, including an installation support frame 1 arranged on a concrete truck. A conveying tank 2 for storing and conveying concrete is arranged on the installation support frame 1. The concrete to be conveyed is stored in the conveying tank 2, and the installation support frame 1 and the conveying tank 2 are driven by the concrete truck to move as a whole, so as to realize the rapid conveying of concrete.

[0025] This conveying device further includes: An adjusting unit is arranged between the conveying tank 2 and the installation support frame 1 to adjust the angle of the conveying tank 2. By adjusting the inclination angle of the conveying tank 2 through the adjusting unit, the gravity effect is used to improve the conveying efficiency of the concrete in the conveying tank 2. At the same time, the overall rotation of the conveying tank 2 is realized, so as to drive the concrete in the conveying tank 2 to be stirred during the concrete conveying process, and avoid phenomena such as segregation and hardening of the concrete in the conveying tank 2; A cleaning unit is arranged on the conveying tank 2 to realize the pushing, cleaning and stirring and mixing of the concrete inside the conveying tank 2, improve the conveying efficiency of the concrete, and avoid the accumulation of concrete at the bottom of the conveying tank 2 through the pushing and scraping actions inside the conveying tank 2. At the same time, the inner wall of the conveying tank 2 is cleaned to avoid the adhesion and solidification of the concrete on the inner wall of the conveying tank 2.

[0026] Embodiment 2: Refer to Figures 2 - 5 , the different technical solutions of this embodiment compared with Embodiment 1 are as follows: A driving component and an angle adjusting component are arranged in the adjusting unit. A driving roller 8 for driving is arranged in the driving component. Two hydraulic adjusting rods 7 are arranged in the angle adjusting component. The two hydraulic adjusting rods 7 are used to adjust the inclination degree of the conveying tank 2, thereby improving the conveying speed of the concrete; The angle adjusting component includes two hydraulic adjusting rods 7 fixedly installed in the installation support frame 1. Telescopic jacking rods are fixedly installed on the driving ends of the two hydraulic adjusting rods 7. Two sleeved support rings 4 are rotatably sleeved on the outer side of the conveying tank 2. And limit rotating rollers 16 are rotatably installed in the two sleeved support rings 4, and the two telescopic jacking rods are respectively rotatably connected with the two limit rotating rollers 16; When the two hydraulic adjustment rods 7 are activated, they will drive the two telescopic lifting rods on their driving ends to move, thereby pushing the limit rollers 16 on them and the sleeved support ring 4 to adjust the height. Moreover, the two hydraulic adjustment rods 7 act in the opposite direction. That is, when the left hydraulic adjustment rod 7 drives the left telescopic lifting rod to move up by the same distance, the right hydraulic adjustment rod 7 drives the right telescopic lifting rod to move down by the same distance.

[0027] A middle support ring 5 is rotatably installed on the outer side of the conveying tank 2. Two deflection support shafts 13 are rotatably installed on the outer side of the middle support ring 5, and the two deflection support shafts 13 are respectively rotatably installed on the two inner sides of the installation support frame 1; When discharging and conveying the concrete in the conveying tank 2, the left hydraulic adjustment rod 7 can be activated to drive the left telescopic lifting rod and the sleeved support ring 4 to move up, and at the same time, the right hydraulic adjustment rod 7 is activated to drive the right telescopic lifting rod and the sleeved support ring 4 to move down. That is, with the middle deflection support shaft 13 as the central axis, the conveying tank 2 can be driven to rotate as a whole, making the conveying tank 2 form an inclined state with the left side high and the right side low. At this time, the concrete in the conveying tank 2 will automatically slide down under the action of gravity, which can effectively improve the conveying efficiency of the concrete.

[0028] The limit roller 16 plays a role in limit adjustment. When the telescopic lifting rod drives the sleeved support ring 4 to lift or lower, the limit roller 16 can rotate correspondingly. This can effectively avoid the jamming situation that occurs when the telescopic lifting rod drives the sleeved support ring 4 to tilt. Since the angle of the telescopic lifting rod remains unchanged while the angle of the sleeved support ring 4 changes, the automatic adjustment of the support connection angle can be achieved through the limit roller 16, realizing the smooth deflection of the sleeved support ring 4.

[0029] In a further embodiment, the drive assembly includes a driven mounting frame 11 fixedly installed between the two sleeved support rings 4. A servo motor 12 is fixedly installed on the driven mounting frame 11, and the drive roller 8 is fixedly arranged on the drive end of the servo motor 12; When the servo motor 12 is activated, it will drive the drive roller 8 to rotate. The rotation direction of the drive roller 8 can be controlled by the servo motor 12 to realize the forward and reverse rotation of the drive roller 8.

[0030] An external gear ring 6 is fixedly installed on the outer side of the conveying tank 2, and a drive gear 14 meshing with the external gear ring 6 is fixedly installed on the drive roller 8. When the drive roller 8 rotates, it will drive the drive gear 14 to rotate. When the drive gear 14 rotates, it will drive the external gear ring 6 meshing with it to rotate, thereby driving the conveying tank 2 to rotate as a whole. During the concrete conveying process, the conveying tank 2 can be driven to rotate by the drive of the servo motor 12, and then the concrete in the conveying tank 2 can be slowly stirred to avoid the segregation and hardening of the concrete; Both the two nested support rings 4 and the middle support ring 5 are rotatably connected to the conveying tank 2. When the conveying tank 2 rotates, the two nested support rings 4 and the middle support ring 5 will not rotate therewith. That is, the angle adjustment of the conveying tank 2 will not affect the rotation of the conveying tank 2, and the rotation of the conveying tank 2 will not affect its angle adjustment.

[0031] Embodiment 3: Refer to Figures 1 - 2 and Figures 6 - 15 , the different technical solution of this embodiment compared with Embodiment 2 is that: the cleaning unit is driven by the driving roller 8 and includes an inner scraping component, a plugging component and a conveying component. An inner scraping ring 25 for cleaning the inner wall of the conveying tank 2 is arranged in the inner scraping component. The cooperation between the inner scraping ring 25 and the inner scraping component improves the conveying speed of the concrete in the conveying tank 2.

[0032] The inner scraping component includes a driving shaft 18 rotatably installed in the conveying tank 2, and a transmission mechanism is installed between the driving shaft 18 and the driving roller 8. The transmission mechanism includes a one-way bearing 17 arranged on the driving roller 8, and the one-way bearing 17 cooperates with the reverse rotation of the driving roller 8; When discharging is required, the servo motor 12 can be started to drive the driving shaft 18 to rotate reversely. At this time, when the driving roller 8 rotates reversely, it will drive the one-way bearing 17 to rotate. When the driving roller 8 rotates forward, the one-way bearing 17 will not rotate. That is, when the conveying tank 2 rotates and stirs during the conveying process of the concrete mixer truck, the driving roller 8 rotates forward at this time, that is, the one-way bearing 17 will not rotate; A driving wheel 35 is arranged outside the one-way bearing 17, a driven wheel 36 is fixedly installed on the driving shaft 18, and a transmission belt 10 is sleeved between the driving wheel 35 and the driven wheel 36. When the one-way bearing 17 rotates, it will drive the driving wheel 35 thereon to rotate. When the driving wheel 35 rotates, it will drive the driven wheel 36 to rotate under the cooperation of the transmission belt 10, and then drive the driving shaft 18 to rotate.

[0033] In a further embodiment, a partition plate 19 is rotatably installed in the conveying tank 2, and a feeding mechanism is installed between the partition plate 19 and the conveying tank 2. The partition plate 19 plays a role of separation and is used to isolate the concrete in the conveying tank 2; The feeding mechanism includes a feeding hopper 3 fixedly installed on one of the nested support rings 4 for pouring concrete. A limit rotating ring 15 is rotatably installed on the conveying tank 2, and a feeding pipe 24 is fixedly installed between the limit rotating ring 15 and the feeding hopper 3, and the feeding pipe 24 is fixedly connected to the partition plate 19; The concrete is poured into the feeding pipe 24 through the feeding hopper 3 and then into the conveying tank 2 through the feeding pipe 24, and the conveying and filling of the concrete can be completed; The feed hopper 3 is supported by sleeving a support ring 4 so that it will not rotate with the rotation of the conveying tank 2. At the same time, the limit rotating ring 15 is fixed on the feed pipe 24 and is rotationally connected to the conveying tank 2. When the conveying tank 2 rotates, the limit rotating ring 15 will not move relative to the feed pipe 24 and the partition plate 19. Thus, the relative positions of the feed pipe 24, the limit rotating ring 15, and the partition plate 19 can always remain unchanged.

[0034] In a further embodiment, a pushing mechanism is installed on the driving shaft 18. The pushing mechanism includes a reciprocating lead screw 26 fixedly installed on the driving shaft 18. A ball nut plate 29 is fitted on the reciprocating lead screw 26. A pushing plate 20 for pushing concrete is fixedly installed on the ball nut plate 29, and the pushing plate 20 is in contact with the inner wall of the conveying tank 2. The pushing plate 20 is slidably connected to the feed pipe 24, so that when the pushing plate 20 slides during pushing, it will not affect the feed pipe 24, and the concrete injected into the feed pipe 24 will be directly injected to the right side of the pushing plate 20 (the direction shown in the attached Figure 8 specification).

[0035] When the driving shaft 18 rotates, it will drive the reciprocating lead screw 26 thereon to rotate. When the reciprocating lead screw 26 rotates, it will drive the ball nut plate 29 fitted thereon to move. According to the characteristics of the ball nut plate 29 and the reciprocating lead screw 26, under the continuous rotation of the reciprocating lead screw 26, the ball nut plate 29 is driven to reciprocate horizontally on the reciprocating lead screw 26, and then the pushing plate 20 is driven to reciprocate in the conveying tank 2. When the pushing plate 20 reciprocates, it can push the concrete in the conveying tank 2 to move forward, and then the concrete at the bottom of the conveying tank 2 can be pushed forward, effectively avoiding the accumulation of concrete at the bottom of the conveying tank 2 and improving the conveying efficiency of the concrete.

[0036] The cooperation between the reciprocating lead screw 26 and the ball nut plate 29 is a prior art. The specific principle is as follows: The reciprocating lead screw 26 is a form of solid cam pair, which is manifested as two helical grooves with the same pitch and opposite helix directions. The two ends of the lead screw are connected by transition curves. The balls in the ball nut plate 29 are placed inside the helical grooves. Through the rotation of the lead screw, the inner groove side of the helical groove pushes the balls inside to make axial reciprocating motion, thereby driving the ball nut plate 29 to make reciprocating movement. That is, when the reciprocating lead screw 26 rotates unidirectionally, it can drive the ball nut plate 29 to make reciprocating linear movement on the reciprocating lead screw 26. This part is prior art and will not be elaborated here.

[0037] A plurality of linkage rods 28 are fixedly installed on the pushing plate 20, and an inner scraping ring 25 is fixedly installed on the plurality of linkage rods 28 together. The inner scraping ring 25 is in contact with the inner wall of the conveying tank 2. When the pushing plate 20 reciprocates, the inner scraping ring 25 thereon will be driven by the plurality of linkage rods 28 to reciprocate. When the inner scraping ring 25 reciprocates, the concrete attached to the inner wall of the conveying tank 2 can be scraped off, which can not only prevent the concrete from accumulating and solidifying on the inner wall of the conveying tank 2, but also push the concrete forward, improving the pushing and output efficiency of the concrete.

[0038] In a further embodiment, the blocking assembly is used to control the discharging range of the concrete in the conveying tank 2. The blocking assembly includes two pushing frames 27 fixedly installed on the inner scraping ring 25, and a blocking plate 22 for blocking the concrete is fixedly installed on the two pushing frames 27 together. A blocking box 21 is rotatably installed in the conveying tank 2, and a clamping ring groove 32 matching with the blocking plate 22 is opened in the blocking box 21. A plurality of return springs 31 are fixedly installed between the clamping ring groove 32 and the blocking plate 22, and a plurality of air exchange holes 30 are opened on the blocking plate 22; In the initial state, the blocking plate 22 will be clamped into the clamping ring groove 32 in the blocking box 21, so as to block the blocking box 21, so that the concrete in the conveying tank 2 will not be conveyed and discharged during the conveying and rotating process of the conveying tank 2. The plurality of air exchange holes 30 on the blocking plate 22 are used for ventilation and air exchange of the concrete in the conveying tank 2, so as to ensure the balance of temperature and humidity in the conveying tank 2 and avoid the situation of overheating and hardening.

[0039] When the inner scraping ring 25 reciprocates, it will drive the blocking plate 22 to reciprocate through the two pushing frames 27. When the blocking plate 22 is pushed forward, it will be separated from the clamping ring groove 32 in the blocking box 21. At this time, the blocking box 21 is in a communicating state, and the concrete in the conveying tank 2 can be discharged through the blocking box 21, so as to carry out the discharging of the concrete; When the blocking plate 22 retracts, it will block the blocking box 21 again, so as to realize the intermittent discharging of the concrete, and further control the conveying and discharging content of the concrete better. At the same time, it is convenient to cooperate with the conveying assembly to improve the mixing effect of the concrete.

[0040] In a further embodiment, a spiral pushing blade 23 for pushing the concrete to be conveyed and discharged is arranged in the conveying assembly. The conveying assembly includes a stirring shaft 33 fixedly installed on the driving shaft 18, and a plurality of stirring members 34 for stirring the concrete are fixedly installed on the stirring shaft 33; When the driving shaft 18 rotates, it will drive the stirring shaft 33 to rotate. When the stirring shaft 33 rotates, it will drive the plurality of stirring members 34 thereon to rotate. When the plurality of stirring members 34 rotate, they will stir the concrete in the conveying tank 2, so as to make the interior of the concrete mix evenly and avoid situations such as hardening and segregation.

[0041] The spiral pushing blade 23 is fixedly installed on the outside of the stirring shaft 33, and a plurality of stirring members 34 are all located inside the spiral pushing blade 23, so that the stirring of the stirring members 34 will not affect the spiral pushing blade 23; The spiral pushing blade 23 rotates with the rotation of the stirring shaft 33, and can push the concrete in the conveying tank 2 to move during the rotation process, realizing the forward pushing and conveying of the concrete. That is, under the combined action of the inclination of the conveying tank 2 and the pushing action of the pushing plate 20, the efficient conveying and discharging of the concrete in the conveying tank 2 can be realized, which can effectively improve the discharging efficiency of the concrete and avoid the accumulation and residue of the concrete.

[0042] The specific conveying principle of this conveying device is as follows: First, pour the concrete into the feeding pipe 24 through the feeding hopper 3, and then pour it into the conveying tank 2 through the feeding pipe 24. Then, drive the installation support frame 1 and the conveying tank 2 to move as a whole by the concrete transport vehicle to transport the concrete to the predetermined position; During the concrete conveying process, drive the driving roller 8 to rotate by the drive of the servo motor 12, and then drive the driving gear 14 to rotate. When the driving gear 14 rotates, it drives the externally meshed tooth ring 6 to rotate, so as to drive the conveying tank 2 to rotate as a whole, and slowly stir the concrete in the conveying tank 2 to avoid the segregation and hardening of the concrete.

[0043] After the concrete is transported to the predetermined position, start the left hydraulic adjusting rod 7 to drive the left telescopic lifting rod and the sleeved support ring 4 to move upward, and at the same time start the right hydraulic adjusting rod 7 to drive the right telescopic lifting rod and the sleeved support ring 4 to move downward. That is, with the middle deflection support shaft 13 as the central axis, drive the conveying tank 2 to rotate as a whole, so that the conveying tank 2 forms an inclined state with the left side high and the right side low. At this time, the concrete in the conveying tank 2 will automatically slide down under the action of gravity, and the conveying and discharging work of the concrete can start; Start the servo motor 12 to drive the driving roller 8 to reverse, drive the driving shaft 18 to rotate through the cooperation of the transmission mechanism. When the driving shaft 18 rotates, drive the pushing plate 20 to move reciprocally, push the concrete in the conveying tank 2 to move forward, and then can push the concrete at the bottom of the conveying tank 2 forward, effectively avoiding the accumulation of the concrete at the bottom of the conveying tank 2 and improving the conveying efficiency of the concrete; When the pushing plate 20 moves reciprocally, it will drive the inner scraping ring 25 on it to move reciprocally through a plurality of linkage rods 28. When the inner scraping ring 25 moves reciprocally, it can scrape off the concrete attached to the inner wall of the conveying tank 2, which can not only avoid the accumulation and solidification of the concrete on the inner wall of the conveying tank 2, but also push the concrete forward, improving the pushing and output efficiency of the concrete.

[0044] When the inner scraper ring 25 reciprocates, it drives the blocking plate 22 to reciprocate through the two pushing frames 27. When the blocking plate 22 is pushed forward, it is separated from the engaging ring groove 32 in the blocking box 21. At this time, the blocking box 21 is in a connected state.
