[0002] Among the many construction processes in the field of building construction, the plastering process on the wall surface has always been an extremely important process. The traditional plastering process is basically completed by workers manually. However, higher-standard construction specifications require construction workers to have a high level of technical skills and proficiency. Due to the huge workload and high labor intensity, the construction efficiency is generally low, and the flatness and compression of the plaster applied on the wall are difficult to guarantee, making it difficult to meet the requirements of high-quality plastering operations.

DETAILED DESCRIPTION

[0031] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that these equivalent forms also fall within the scope defined in this application.

[0032] Example: As shown in the attached Figure 1 As shown, the present invention is an indoor automatic plastering machine for house construction, which is mainly composed of a quick-install guide rail system 100, a telescopic frame mechanism 200, a shift fork wheel adjustment mechanism 300, an automatic leveling and transverse movement mechanism 400, and a plastering mechanism 500.

[0033] like Figure 2-4 As shown, the quick-install guide rail system 100 is mainly composed of a laser leveling instrument auxiliary positioning device, a plastering machine transverse guide rail 112 and a guide rail quick locking mechanism.

[0034] The laser leveling instrument auxiliary positioning device mainly consists of a laser leveling instrument guide rail base 101, a leveling instrument guide rail 102, a slider 103, a slider locking round nut 104, a fine-tuning base 105 and a laser leveling instrument 106.

[0035] Before plastering, first determine the reference line of the plastering machine transverse guide rail 112 to facilitate the placement of the plastering machine transverse guide rail 112. The specific method is as follows: Figure 5 As shown, the laser leveling instrument auxiliary positioning device determines the most convex part of the wall as the reference surface by adjusting the distance between the leveling instrument and the wall, which is the wall laser leveling line. The laser leveling instrument can slide on the guide rail and determine the intended installation position of the plastering machine transverse guide rail 112 according to the mechanical structure and the plastering thickness, which is the guide rail center line. When placing the plastering machine transverse guide rail 112, the guide rail reference can be established by aligning the guide rail center line with the center line.

[0036] One end of the transverse guide rail pad 107 is provided with a card slot, a handwheel rotary lock clamping piece 110, and an anti-loosening compression spring 111, which are used to realize the quick connection of the guide rail; the other end is provided with a push pin 108 and a tightening bolt 109. When placing the transverse guide rail 112, the center line of the guide rail is used as the positioning reference. For walls in different positions, the push pin 108 can be adjusted to extend to the corresponding length and the tightening bolt 109 to ensure that the push pin can better lean against the wall, thereby increasing the stability of the V-wheel walking mechanism.

[0037] The transverse guide rails 112 can be connected by a handwheel lock mechanism, and the combination of guide rails of different lengths can be flexibly adapted to multi-size scene applications.

[0038] As attached Figure 6-8As shown, the telescopic frame mechanism 200 is mainly composed of a main frame assembly at the bottom, a sleeve mechanism at the middle position, a telescopic lifting assembly at the top, a matching telescopic frame wire hoisting mechanism, and a plastering wire hoisting mechanism.

[0039] The main frame assembly consists of longitudinal columns 201, longitudinal guide tubes 202, a transverse chassis 203, reinforced tubes 204, a chassis box 205, and a control box 206. The longitudinal columns 201 are arranged symmetrically, with the guide tubes 202 in the middle and the transverse chassis 203 at the bottom. The main frame assembly has reinforced square tubes on the top and reinforced tubes 204 welded to the sides to increase the frame's stability.

[0040] The telescopic lifting assembly is composed of a telescopic frame column assembly 214, a telescopic frame circular tube frame 223, a rubber pad 224, etc. The columns and circular tubes in the telescopic lifting assembly are respectively nested in the columns and circular tubes of the main frame.

[0041] In order to better connect the smooth operation of the plastering assembly between the main frame and the telescopic jacking frame, the sleeve mechanism is mainly composed of a sliding sleeve 216, a sleeve linkage block 215, a tension spring 217, a hook plate 218, a hook plate rotating shaft 219, and a hook plate hook column 220. The sliding sleeve 216 and the longitudinal column of the main frame have the same cross-sectional dimensions and are arranged symmetrically on the left and right. The sleeve linkage block 215 is welded above the sliding sleeve 216. The function of the sleeve assembly is to achieve plastering of higher walls. The initial state of the sleeve assembly is that the hook plate 218 rotates upward along its rotating shaft 219 under the pull of the tension spring 217, so that the hook plate 218 is always hooked on the hook column 220 below. When the upward plastering is working, the plastering wire winch mechanism Under the drag of 207, the protruding column 505 on the plastering frame 501 first knocks open the hook plate 218, so that the hook plate 218 and the hook column 220 are disengaged, and then the plastering frame connecting block 503 contacts the sleeve linkage block 215 and moves upward together with the plastering wire hoisting mechanism 207. When working downward, the sleeve assembly descends together with the plastering mechanism. When the lower end reaches the upper end surface of the longitudinal column of the main frame, since the sliding sleeve and the longitudinal column of the main frame have the same cross-sectional dimensions, they are stuck and stop, and the plastering mechanism continues to descend, and the plastering frame connecting block 503 is disengaged from the sleeve linkage block 215. Under the action of the tension spring 217, the hook plate 218 is hooked on the hook column 220, thereby realizing the resetting of the hook plate 218.

[0042] The telescopic frame hoisting mechanism is mainly composed of a telescopic frame hoist 208, a pulley 228, a wire rope 229, a pressure sensor 225, etc.

[0043] The plastering winch mechanism mainly includes a plastering winch 207, a pulley 221, a wire rope 220, a plastering lower stop travel switch 209, a lower travel switch trigger linkage plate 210, a nozzle plate reset touch plate 211, an electric push rod 212, an unlocking torsion shaft 213, and a plastering upper stop travel switch 518.

[0044] The shift fork wheel adjustment mechanism 300 is located at the bottom of the main frame. Figure 9 and Figure 10 As shown, the fork mechanism adjusts the distance between the wheels in the front-to-back direction, reducing the distance between the center of gravity of the machine and the wheels. This allows construction workers to quickly and easily tilt the vehicle body to a certain angle, allowing the V-wheels to fit onto the guide rails. Furthermore, the machine can be more easily transported through short doorways and obstacles at the construction site. The fork wheel adjustment mechanism 300 primarily consists of a wheel 308, a universal wheel 315, a locking nut 309, a wheel axle 301, a wheel axle shifting column 307, a rolling bearing 302 and its mounting plate 303, a bolt bearing 306 and its bearing plate 305, and a fork mechanism. The fork mechanism further comprises a fork link 1 310, a fork link 2 311, a fork link 312, a floating pressure plate 313, and a tension spring 314.

[0045] like Figure 11 As shown, the automatic leveling and traversing mechanism 400 primarily consists of a support plate 401, linear bearings 402, guide posts 403, a leveling cylinder 404, a posture sensor 405, an AGV wheel bracket 406, an AGV wheel 407, and a V-wheel 408. This lightweight design enables automatic leveling and traversing of the plastering machine during operation. The V-wheel 408, which travels along the traversing guide rail 112, ensures consistent plastering distance. The AGV's automatic travel wheels ensure accurate traversing position. Once the traversing is in place, the leveling cylinder automatically adjusts the vehicle body based on data from the posture sensor, ensuring verticality in the plastering process.

[0046] Before plastering work, the posture sensor 405 in the automatic leveling transverse movement mechanism 400 detects whether the vehicle body is horizontal, and can control the leveling electric cylinder 404 to automatically level the vehicle body, and then the telescopic jacking assembly is gradually lifted to the roof through its wire hoisting mechanism. The jacking force is set by the pressure sensor 225. An anti-slip rubber pad 224 is installed above the jacking assembly to increase stable support during plastering work. During plastering, the plastering mechanism moves in the up and down directions of the frame through its matching wire hoisting mechanism, and at the same time cooperates with the sleeve assembly to complete the construction requirements of walls of different heights.

[0047] Plastering mechanism 500, such as Figure 12 and Figure 13As shown, the mechanism is mainly composed of a plastering frame 501, a lower plastering plate 507, an upper plastering plate 512, a nozzle plate 522 and its supporting connecting rod mechanism, a mortar feeding mechanism and a vibration compaction mechanism. The plastering mechanism 500 drives the lifting wheel 506 under the drive of its wire winch mechanism, so that the walking wheel 504 in the frame moves up and down along the main frame and its sleeve assembly to realize the plastering work. In order to avoid the waste caused by the overflow of plaster from both sides during the plastering process, the mechanism is equipped with a mudguard 528. In addition, a sealing plate 529 is also provided to keep the mechanism clean.

[0048] The plastering frame 501 is the main frame of the plastering mechanism, and its two side plates are arranged symmetrically. The front end is connected to the upper plastering plate 512, the lower plastering plate 507 and the nozzle plate 522 and other components. The upper part of the rear end is welded with an angle iron, and the lower part of the rear end is welded with a plastering frame cross brace 502. The frame lifting wheel 506 is arranged on the plastering frame cross brace 502, and the frame walking wheel 504 is installed on the side plate. In this way, the lifting wheel can drive the plastering frame to move up and down under the drive of the wire rope.

[0049] The lower smear plate connecting rod mechanism is mainly composed of the lower smear plate 507, the lower smear plate connecting rod 508, the lower smear plate gas spring 1 509, the lower smear plate rotating shaft 510, the lower smear plate gas spring 2 511 and other components; the upper smear plate connecting rod mechanism is mainly composed of the upper smear plate 512, the upper smear plate gas spring 513, the upper smear plate connecting rod 514, the hook 515, the torsion spring 516, the tension spring 517, the plastering upper stop travel switch 518 and other components; the upper and lower smear plates are connected by the smear plate hinge 530.

[0050] The nozzle plate connecting rod mechanism mainly consists of components such as the nozzle plate bracket 520, the nozzle plate 522, the rotating shaft vertical connecting rod 525, the nozzle plate connecting rod 526 and the torsion spring 527. In the initial state, the slot below the nozzle plate connecting rod is stuck on the plastering frame cross brace 502.

[0051] The mortar feeding mechanism mainly includes a reciprocating screw assembly 521, a mortar nozzle 523, a feed pipe 524 and other components.

[0052] The vibration compaction mechanism mainly includes a vibration motor and its mounting plate. The vibration motor 519 is installed behind the upper plastering plate 512 and is responsible for providing high-frequency vibration for the plastering plate to ensure that the mortar is tightly combined with the wall surface and improve the density and uniformity of the plastering.

[0053] When plastering upward, the initial state of the upper and lower plastering plates is as follows: Figure 13 As shown: the upper trowel plate 512 is tilted at a certain angle, and the lower trowel plate 507 is in a vertical state. The upper trowel plate 512 is tilted at a certain angle to ensure smooth upward movement and prevent scratches. At the same time, it can also store a certain amount of mortar. The lower trowel plate 507 is in a vertical state to better smooth the mortar.

[0054] The plastering program is started through the control panel, and the mortar is sprayed out from the nozzle 523 through the feed pipe 524. Driven by the reciprocating screw 521, it moves left and right to spray the mortar evenly onto the wall. At the same time, the upper and lower plastering plates are gradually raised under the drag of their hoisting mechanisms. During the plastering process, the vibration motor 519 is started to provide high-frequency vibration for the plastering plate. During the plastering operation, the exciting force of the vibration motor 519 can ensure that the mortar is tightly combined with the wall, thereby improving the density and uniformity of the plastering.

[0055] When the plastering mechanism returns downward, the nozzle plate connecting rod 526 touches the mortar pumping stroke switch 226 on the jacking frame, the pump stops supplying mortar, and no more mortar is sprayed during the downward process. In fact, it is a process of compacting and smoothing the plastered surface that has been plastered during the previous upward movement. At this time, the upper and lower plastering plate mechanisms are connected by the top pressure of the upper plastering plate connecting rod touch plate 227 in the jacking frame and the linkage of the nozzle plate connecting rod mechanism. The upper plastering plate 512 is in a vertical state and the lower plastering plate 507 is in a certain inclination state. The two states are as follows Figure 14 shown.

[0056] As the plastering mechanism 500 approaches the bottom of the frame, the nozzle plate connecting rod 526 gradually approaches the reset touch plate 211 in the main frame. The horizontal support 502 on the plastering frame gradually engages the slot below the nozzle plate connecting rod 526, thereby causing the nozzle plate 522 to reset the nozzle plate assembly. Simultaneously, as the nozzle plate 522 resets, its vertical connecting rod 525 drives the lower wiper plate rotating shaft 510 to rotate in the opposite direction. This rotates the lower wiper plate 507 from its downward tilted state to its initial vertical state, completing the reset of the lower wiper plate assembly.

[0057] As the plastering mechanism 500 continues to descend, the lower end surface of the plastering frame 501 in the plastering mechanism 500 will gradually approach and touch the lower stop travel switch in the main frame to trigger the linkage plate 210, and then trigger the plastering lower stop travel switch 209. Under the action of this travel switch, the plastering winch motor 207 stops and the plastering downward movement is completed.

[0058] Finally, under the automatic control of the plastering program, the electric push rod 212 pulls the unlocking torsion shaft 213, causing it to move the hook 515 on the upper plastering plate connecting rod 514 and disengage it from the plastering frame 501. The upper plastering plate connecting rod 514 bounces upward under the pull of the tension spring 517, so that the upper plastering plate 512, driven by its connecting rod, changes from the vertical state at this time to the initial state with a certain inclination angle. The upper plastering plate assembly is reset, and the plastering work of a wall is completed.

[0059] Before plastering the next wall, the lifting mechanism above the telescopic frame mechanism needs to be lowered a little to separate the frame from the ceiling of the house. After that, the vehicle body is driven by the AGV wheel 407, and the V wheel 408 moves to the right along the previously placed transverse guide rail 112. After the transverse movement is in place, the leveling cylinder 404 adjusts the level of the vehicle body according to the data of the posture sensor 405. Then, the lifting frame is lifted to the ceiling again to increase the stable support for the frame. In this way, the rotation work before plastering is completed. After that, the plastering mechanism repeats the previous plastering process to plaster the wall.
