Description

Technical Field

[0001] This invention relates to the field of aerated concrete block construction technology, specifically to an auxiliary device and method for aerated concrete block construction. Background Technology

[0002] Aerated concrete blocks are a new type of green, energy-saving, environmentally friendly, and waste-utilizing building material. Using aerated concrete blocks to build walls can help reduce the building's self-weight and lower project costs.

[0003] Currently, if aerated concrete block walls are constructed manually, the mortar overflowing from the joints between adjacent blocks needs to be cleaned manually. Due to the large size of the aerated concrete blocks and the long joints, workers have to clean while building, resulting in high labor intensity and low efficiency in both construction and cleaning. If automated robots are used to build aerated concrete block walls, the lack of cleaning devices means that the mortar overflowing from the joints between adjacent blocks cannot be cleaned in time. This causes the overflowing mortar to easily scatter onto the surface of the aerated concrete blocks, the ground, and automated equipment, polluting the construction environment. Furthermore, the scattered mortar cannot be recycled, resulting in mortar waste. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary device and method for aerated concrete block construction, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An auxiliary device for aerated concrete block construction includes a vehicle body, a lifting platform, a moving component, a working plate, and scraping components. The vehicle body is placed on the ground on one side of the aerated concrete block and moves horizontally along the construction direction. The moving component is positioned above the vehicle body and includes a lifting platform. The lifting platform is positioned between the vehicle body and the lifting platform. A mortar box is fixedly installed on the side of the lifting platform near the aerated concrete block. The working plate is positioned on the side of the moving component near the aerated concrete block and is movably connected to the moving component. Multiple scraping components are evenly spaced on the side of the working plate near the aerated concrete block and are movably connected to the working plate. Each scraping component includes a scraper for scraping mortar horizontally or vertically. The scraped mortar enters the mortar box.

[0007] Furthermore, the moving assembly also includes a push rod, a horizontal slide, and a vertical slide. The horizontal slide is located on the upper part of the lifting platform near the gas block and is slidably connected to the lifting platform. The two ends of the push rod are respectively connected to the side of the lifting platform away from the gas block and the horizontal slide. The vertical slide is driven by the horizontal slide through a horizontal screw mechanism, and the middle part of the working plate is driven by the vertical screw mechanism.

[0008] Furthermore, one or more sliders are slidably arranged at both ends of the working plate. The sliders are locked to the working plate by spring pins. A vertical plate is fixedly arranged on the middle of the slider and the side of the working plate near the gas block. A floating column is slidably arranged at the upper end of the vertical plate. One end of the floating column is connected to the vertical plate by a floating spring, and the other end is fixedly connected to the scraping component.

[0009] Furthermore, the scraping assembly also includes a reversing joint and a bending arm, used to switch the scraper to a vertical scraping or horizontal scraping working state. The reversing joint is fixedly connected to the floating column, and the two ends of the reversing joint are symmetrically rotatably provided with first bevel gears. One end of the bending arm is vertically fixedly provided with a second bevel gear, and the other end is hinged to the back of the scraper. The second bevel gear is respectively meshed with two first bevel gears, and the second bevel gear is rotatably connected to the reversing joint.

[0010] Furthermore, a funnel is detachably connected to the lower end of the vertical plate. The funnel is located below the scraping assembly, and a pipe connects the lower part of the funnel to the mortar box.

[0011] Furthermore, drive wheels are installed on both sides of the vehicle body, a controller is installed on the vehicle body, and a camera is installed at the upper middle part of the working plate facing the gas block. The controller is electrically connected to the drive wheels, the lifting platform, the camera, the push rod, the horizontal lead screw mechanism, the vertical lead screw mechanism, and the scraping assembly.

[0012] Furthermore, the mortar box is equipped with a paddle, and an extrusion nozzle is provided at the lower end of one end of the mortar box, with a valve installed at the extrusion nozzle.

[0013] Furthermore, a guide nozzle is fixedly connected to the side of the scraper away from the curved arm.

[0014] The present invention also provides a method for constructing aerated concrete blocks, applied to the aforementioned auxiliary device for constructing aerated concrete blocks, comprising the following steps:

[0015] S1: Adjust the position of the corresponding slider according to the length of the aerated concrete blocks to be laid;

[0016] S2: Construct aerated concrete blocks of the current floor height. Adjust the lifting height of the elevator according to the current floor height, and move the vehicle to the position of the aerated concrete blocks close to the current floor height.

[0017] S3: The scraper switches to the vertical scraping working state.

[0026] 2. The aerated concrete block masonry auxiliary device provided by the present invention collects the scraped mortar in a mortar box, which avoids the overflowing mortar from scattering everywhere and helps to ensure the cleanliness of the construction environment. The mortar box continuously stirs the mortar to prevent the mortar from hardening. The mortar in the mortar box can be recycled and reused, which helps to save building resources and reduce construction costs.

[0027] 3. The present invention provides a method for constructing aerated concrete blocks, which uses the aforementioned auxiliary device for constructing aerated concrete blocks to perform auxiliary mortar scraping work layer by layer as the aerated concrete blocks are constructed, thereby enabling timely scraping of overflowing mortar without affecting the aerated concrete block construction work.

The joints between adjacent ACBs 6 are constructed with mortar. The vehicle body 1 is placed on the ground on one side of the ACBs 6 and moves horizontally along the construction direction of the ACBs 6. The moving component 3 is positioned above the vehicle body 1 and includes a lifting platform 31. The lifting platform 2 is positioned between the vehicle body 1 and the lifting platform 31. A mortar box 35 is fixedly installed on the side of the lifting platform 31 near the ACBs 6.

[0043] Furthermore, drive wheels 11 are installed on both sides of the vehicle body 1. The drive wheels 11 are driven by a motor to drive the vehicle body 1 to move. This is existing technology and will not be described in detail. A counterweight block 12 is placed on the side of the vehicle body 1 away from the gas block 6 to prevent the device from tipping over. The lifting platform 2 is a scissor lift structure, including a lifting hydraulic cylinder 21, scissor arms 22, and a lifting base 23. The lifting base 23 is fixedly installed on the upper part of the side of the vehicle body 1 near the gas block 6. The upper part of the lifting base 23 is connected to the lower part of the lifting platform 31 through two stages of scissor arms 22. The two stages of scissor arms 22 are hinged. The two sides of the upper end of the lifting base 23 are respectively connected to the two scissor arms 22 located at the lower part.

The fixed end of the lifting hydraulic cylinder 21 is hinged to the scissor arms 22 slidably connected on the lifting base 23, and the movable end of the lifting hydraulic cylinder 21 is hinged to the pin in the middle of the upper scissor arms 22. The specific scissor lifting structure is existing technology and will not be described in detail.

[0044] Furthermore, the moving component 3 also includes a push rod 32, a horizontal slide block 33, and a vertical slide block 34. The horizontal slide block 33 is located on the upper part of the lifting platform 31 near the gas block 6. The lifting platform 31 has symmetrically provided limit grooves 311 at both ends. Limit plates are symmetrically fixed at both ends of the horizontal slide block 33, and the limit plates slide in cooperation with the limit grooves 311. The push rod 32 is located in the middle of the upper part of the lifting platform 31. The fixed end of the push rod 32 is fixedly connected to the side of the lifting platform 31 away from the gas block 6, and the movable end of the push rod 32 is fixedly connected to the horizontal slide block 33. Activating the push rod 32 can adjust the distance between the horizontal slide block 33 and the gas block 6.

[0045] A horizontally arranged horizontal sliding screw 331 is mounted in the middle of the horizontal sliding block 33. Both ends of the horizontal sliding screw 331 are rotatably connected to both ends of the horizontal sliding block 33. One end of the horizontal sliding screw 331 is connected to a horizontal moving motor 332. The lower end of the vertical sliding block 34 is slidably mounted inside the horizontal sliding block 33. The lower end of the vertical sliding block 34 is threadedly connected to the horizontal sliding screw 331. A vertically arranged vertical sliding screw 341 is mounted in the middle of the vertical sliding block 34. The upper and lower ends of the vertical sliding screw 341... The upper and lower ends of the vertical sliding block 34 are rotatably connected to each other. The upper end of the vertical sliding screw 341 is connected to the vertical sliding motor 342. A boss 41 is fixedly provided in the middle of the working plate 4 on the side away from the gas block 6. The boss 41 is slidably disposed in the vertical sliding block 34. The boss 41 is threadedly connected to the vertical sliding screw 341. When the horizontal sliding motor 332 is started, the working plate 4 can move in the horizontal direction. When the vertical sliding motor 342 is started, the working plate 4 can move in the vertical direction.

[0046] Furthermore, a camera 46 is installed at the upper center of the side of the working plate 4 facing the aerated concrete block 6 to detect the relative position between the working plate 4 and the aerated concrete block 6. The working plate 4 has symmetrically arranged grooves 43 at both ends, which are horizontally positioned. Several positioning holes 431 are symmetrically arranged on the upper and lower sides of the grooves 43. The positioning holes 431 are located on the side of the working plate 4 away from the aerated concrete block 6 and are evenly spaced horizontally. One or more sliders 44 are slidably arranged in each groove 43. A positioning block 42 is fixedly connected to the side of the slider 44 away from the aerated concrete block 6. Spring pins 421 are symmetrically arranged at the upper and lower ends of the positioning block 42, with the upper and lower spring pins 421 corresponding to the positioning holes 431 on the upper and lower sides respectively. The pin of 21 is slidably connected to the positioning block 42. One end of the spring pin 421 is connected to the positioning block 42 through the positioning spring, and the other end is slidably engaged with the corresponding positioning hole 431. A handle 422 is slidably provided on the positioning block 42. The upper and lower ends of the handle 422 pass through the upper and lower ends of the positioning block 42 respectively and are fixedly connected with the pins of the upper and lower spring pins 421. Pulling the handle 422 away from the positioning hole 431 separates the spring pin 421 from the positioning hole 431, unlocks the positioning block 42 from the slide groove 43, and the slider 44 can move along the slide groove 43. Releasing the handle 422 engages the spring pin 421 with the positioning hole 431, and the positioning block 42 is locked on the working plate 4. Thus, the distance between the sliders 44 can be adjusted according to the length of the air block 6.

[0047] Furthermore, vertical plates 45 are fixedly installed on the middle of the two sliders 44 and the working plate 4 near the gas block 6. A protrusion 451 extends from the upper end of the vertical plate 45 towards the gas block 6. A floating column 452 is slidably installed inside the protrusion 451. One end of the floating column 452 is connected to the protrusion 451 via a floating spring 453, and the other end extends from the side of the protrusion 451 near the gas block 6. The scraping assembly 5 is fixedly connected to the floating column 452. The moving column 452 acts as a buffer when the push rod 32 pushes the scraping component 5 close to the aerated block 6, so as to avoid the scraper 51 damaging the surface of the aerated block 6 as much as possible. A funnel 47 is provided at the lower end of the vertical plate 45. The funnel 47 is located below the scraping component 5. A pipe is connected between the lower part of the funnel 47 and the mortar box 35. The mortar scraped by the scraping component 5 is received by the funnel 47 and enters the mortar box 35. The funnel 47 and the vertical plate 45 are detachably connected, so as to facilitate the removal and cleaning of the funnel 47.

[0048] Furthermore, the two ends of the mortar box 35 are fixedly connected to the lifting platform 31 by bolts. The mortar box 35 can be removed from the lifting platform 31 and cleaned. The mortar box 35 is equipped with a paddle 351, which is a spiral paddle. One end of the paddle 351 is connected to a stirring motor 352. The lower part of the end of the mortar box 35 away from the stirring motor 352 is provided with an extrusion nozzle 353. The extrusion nozzle 353 is equipped with a valve (not shown in the figure). When the valve is closed, the paddle 351 stirs the mortar in the mortar box 35 to prevent the mortar from hardening. When the valve is opened, the mortar can be extruded from the extrusion nozzle 353 under the conveying of the paddle 351, which facilitates the recycling of mortar.

[0049] Furthermore, the scraping assembly 5 also includes a reversing joint 52 and a bending arm 53. The reversing joint 52 is fixedly connected to the floating column 452. The reversing joint 52 has a first bevel gear 521 symmetrically arranged on the side near the air block 6. The two first bevel gears 521 are rotatably connected to both ends of the reversing joint 52. One of the first bevel gears 521 is connected to a reversing motor 522, which is a reduction motor. A connecting rod is vertically fixedly arranged at one end of the bending arm 53. A second bevel gear 532 is fixedly connected to the end of the connecting rod. The second bevel gear 532 is located between the two first bevel gears 521. The second bevel gear 532 is meshed with the two first bevel gears 521 respectively. The second bevel gear 532 is rotatably connected to the reversing joint 52. When the reversing motor 522 is started, the second bevel gear 532 can rotate around the axis perpendicular to the first bevel gear 521 under the action of gear meshing.

[0050] The end of the curved arm 53 away from the second bevel gear 532 is hinged to the back of the scraper 51. A bending motor 531, a geared motor, is connected to one end of the hinge shaft between the curved arm 53 and the scraper 51. A guide nozzle 511 is fixedly connected to the side of the scraper 51 away from the curved arm 53 to guide the mortar scraped by the scraper 51 into the funnel 47. The scraper 51 has two working states: vertical scraping and horizontal scraping. When the scraper 51 is in the vertical scraping working state, the blade of the scraper 51... With the joint approximately perpendicular to the vertical direction, the bending motor 531 is activated, so that the scraper 51 has a certain angle with the vertical joint, and the scraper 51 can scrape off the mortar at the vertical joint in an inclined posture; when the scraper 51 is in the horizontal scraping working state, with the blade of the scraper 51 approximately perpendicular to the horizontal joint, the reversing motor 522 is activated, so that the scraper 51 rotates to have a certain angle with the horizontal joint, and the scraper 51 can scrape off the mortar at the horizontal joint in an inclined posture.

[0051] Furthermore, a controller 13 is installed on the vehicle body 1. The controller 13 is electrically connected to the drive wheel 11 and the lifting hydraulic cylinder 21, and is used to control the drive wheel 11 and the lifting hydraulic cylinder 21 to move the moving component 3 to the position of the aerated block 6 that needs to be scraped. The controller 13 is electrically connected to the camera 46 and the push rod 32, and is used to receive the detection information from the camera 46 and control the push rod 32 to move the scraper 51 to a position close to the mortar. The controller 13 is electrically connected to the reversing motor 522 and the bending motor 531, and is used to control the reversing motor 522 and the bending motor 531 to switch the scraper 51 to the working state of vertical scraping or horizontal scraping. The controller 13 is electrically connected to the horizontal moving motor 332 and the vertical moving motor 342, and is used to control the horizontal moving motor 332 or the vertical moving motor 342 to make the scraper 51 move horizontally or vertically.

[0052] Preferably, a vacuum pump is connected between the mortar box 35 and the funnel 47. When the vacuum pump is turned on, a negative pressure is generated in the mortar box 35, which facilitates the adsorption of mortar in the funnel 47 and the pipe; the push rod 32 is an electric telescopic rod.

[0053] Preferably, this embodiment uses two sliders 44. According to the length of the gas block 6 and the length of the groove 43, multiple sliders 44 can be set in the groove 43. Multiple scraping components 5 are respectively set in the middle of the corresponding sliders 44 and the working plate 4 on the side facing the gas block 6.

[0054] The present invention also provides a masonry method using the above-mentioned aerated block masonry auxiliary device, comprising the following steps:

[0055] S1: According to the length of the aerated concrete block 6 to be built, operate the handle 422 to adjust the position of the corresponding slider 44 to adjust the distance between the vertical plates 45;

[0056] Furthermore, by adjusting the distance between the vertical plates 45, the distance between adjacent scrapers 51 can be adjusted, flexibly adapting to aerated blocks 6 of different sizes.

[0057] S2: Construct the aerated concrete block 6 at the current floor height. Adjust the lifting height of the elevator 2 according to the current floor height of the aerated concrete block 6. The vehicle body 1 moves to the position of the aerated concrete block 6 that is close to the current floor height.

[0058] S3: Control the reversing motor 522 and bending motor 531 to switch the scraper 51 to the vertical scraping working state. Based on the detection information of the camera 46, control the horizontal movement motor 332 to move the scraper 51 horizontally to a position close to the vertical splice. Start the push rod 32 to push the scraper 51 until its blade is in contact with the vertical mortar.

[0059] S4: Start the vertical movement motor 342, and scraper 51 scrapes the mortar at the joint between the aerated blocks 6 of the current floor height from top to bottom;

[0060] S5: Control the reversing motor 522 and bending motor 531 to switch the scraper 51 to the horizontal scraping working state, start the horizontal movement motor 332, and scraper 51 scrapes the mortar at the joint between the current floor height and the adjacent floor height of the aerated block 6 in the horizontal direction.

[0061] S6: Start the mixing motor 352 and close the valve to continuously mix the mortar in the mortar box 35;

[0062] Furthermore, the mortar overflowing from the joints enters the mortar box 35 through the guide nozzle 511 and funnel 47, which can prevent the mortar from scattering onto the surface of the aerated block 6, the ground, and the surface of automated equipment, thus helping to ensure the cleanliness of the construction site; the mortar is continuously stirred in the mortar box 35, which can prevent the mortar from hardening.

[0063] S7: Vehicle 1 moves along the direction of aerated concrete block 6 construction, repeating S3-S6 until vehicle 1 passes all aerated concrete blocks 6 at the current floor height;

[0064] Furthermore, the scraping component 5 automatically scrapes away the mortar at each joint during the movement of the vehicle body 1, reducing the reciprocating labor of workers when laying aerated blocks, thus reducing the labor intensity of workers and improving the efficiency of laying and cleaning.

[0065] S8: Lay the next layer of aerated concrete block 6, repeat S2-S7, until all aerated concrete blocks 6 are laid;

[0066] Furthermore, as the aerated concrete blocks 6 are laid layer by layer, auxiliary mortar scraping is carried out layer by layer. This allows for timely removal of overflowing mortar, maintaining the construction site environment without affecting the laying of the aerated concrete blocks 6.

[0067] S9: Open the valve to squeeze out and recycle the mortar in the mortar box 35.

[0068] Furthermore, the mortar overflowing from the joints can be recycled and reused after entering the mortar box 35, which helps to save building resources and reduce construction costs.
