Description

Technical Field

[0001] This utility model relates to the field of sprayed wall construction technology, and in particular to a device for controlling the thickness and flatness of phosphogypsum sprayed walls. Background Technology

[0002] In the construction industry, wall construction is a crucial task, as its quality directly impacts the overall performance and lifespan of a building. Particularly in phosphogypsum sprayed wall construction, controlling the thickness and flatness of the walls significantly affects their strength, aesthetics, and subsequent finishing work. High-quality wall construction enhances building safety and comfort, reduces later maintenance costs, and drives the construction industry towards higher quality and efficiency.

[0003] In traditional phosphogypsum sprayed wall construction, several methods were typically used to control the thickness and flatness of the plaster. One method involved using traditional straightedges and plumb lines for measurement and calibration. Workers used straightedges to check the flatness of the wall surface and plumb lines to determine the verticality, thus ensuring basic construction quality. Another common method was to use formwork support. Formwork was erected during wall construction, and spraying and plastering were performed using the formwork as a reference. The shape and size of the formwork controlled the wall thickness and flatness. Additionally, some workers relied on their experience and skills to manually control the spraying and plastering process, constantly observing and adjusting to achieve the required construction standards.

[0004] With the development of automation technology, an automatic wall plastering processing device has emerged, as disclosed in patent announcement number CN 213626526 U. This device uses a drive assembly to move the spraying and coating components reciprocating along the length of the wall, utilizing a reciprocating screw structure to ensure uniform movement speed, thus improving plastering efficiency and uniformity to some extent. However, this device still has significant limitations: its movement is limited to a single direction along the length of the wall, making precise positioning and movement in a two-dimensional plane difficult, thus hindering its suitability for construction scenarios requiring two-dimensional thickness and flatness control; furthermore, the device is functionally limited, only capable of plastering operations, and cannot flexibly switch between spraying and plastering functions on the same device; additionally, the device relies on ground movement and is fixed via casters and a cylinder structure, making its stability highly susceptible to ground flatness, and the installation and leveling process complex.

[0005] Therefore, existing technologies still lack a phosphogypsum spraying wall construction device that can accurately position itself in a two-dimensional plane, support multi-functional construction, and has a stable and reliable reference. The main technical problem to be solved by this application is that existing spraying wall plastering devices can only move in one direction and cannot achieve accurate positioning and continuous construction in a two-dimensional plane. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model solves the technical problem of providing a device for controlling the thickness and flatness of phosphogypsum sprayed walls, thus solving the problem that existing sprayed wall plastering devices can only move in one direction.

[0011] Furthermore, the base is installed at the spatial intersection of the two sets of ball screws and is a circular or square block structure, with the ball screws passing through the base; a hole is provided in the center of the base, and the inner wall of the hole is provided with internal threads.

[0012] Furthermore, a phosphogypsum spraying pipe is installed inside the hole, and the spraying pipe is fixed in the hole of the base by internal threads.

Detailed Implementation

[0024] This application mainly adopts a frame combined with a screw system to control the construction tools, which achieves the effect of accurately controlling the thickness and flatness of the phosphogypsum wall. The following is a further detailed description of this application.

[0025] Example 1 As attached Figure 1-2As shown in the embodiment of this application, the device for controlling the thickness and flatness of phosphogypsum sprayed wall construction includes a frame 1, a slide rail 2, a slider 3, a ball screw 4, and a base 5. The slide rail 2 is located on all four sides of the frame 1. The slider 3 is slidably connected to the slide rail 2. Two adjacent and parallel ball screws 4 form a group, and two groups of ball screws 4 arranged perpendicularly to each other are respectively connected to two opposite sliders 3. The base 5 is installed at the intersection of the ball screws 4, and the center of the base 5 has a hole for installing construction tools. The diameter of the hole is smaller than the net distance between adjacent ball screws 4. The frame 1 is installed on the wall to form a reference. The slide rail 2 and the slider 3 cooperate to drive the ball screw 4 to translate. The ball screw 4 rotates to position the base 5, and the base 5 is used to install construction tools to complete the construction operation.

[0026] Specifically, frame 1 provides support and installation foundation for the entire device. Frame 1 is composed of four steel plates welded together at right angles, forming square fixing ends 11 at the four corners. Frame 1 can be stably installed on the wall to be constructed through these square fixing ends 11, forming a stable reference plane. Multiple bolt holes are provided on the square fixing ends 11, symmetrically distributed. The edges of the bolt holes are chamfered to prevent stress concentration and facilitate bolt insertion. An adjusting bolt hole is located in the center of the square fixing end 11. After the adjusting bolt passes through this hole, its end presses against the wall, and the height of this corner point can be adjusted by screwing it in, thereby achieving horizontal and vertical alignment of the entire frame 1 plane. The square fixing ends 11 are fixed to the wall using expansion bolts or chemical anchors. During installation, the four corner points are initially fixed, then the overall leveling is achieved using the adjusting bolts, and finally all bolts are tightened to ensure the stability of frame 1 without shaking.

[0027] The slide rail 2 is arranged along the four sides of the frame 1, employing a gear and rack transmission mechanism. The rack is laid along the entire length of the slide rail 2 and meshes with the drive gear inside the slider 3. The starting and ending ends of the slide rail 2 are located at the edges of the square fixed plate, and limit blocks 21 are provided at the starting and ending ends to prevent interference between the slider 3 and the square fixed plate. The slide rail 2 is firmly connected to the frame 1 by high-strength bolts or welding to ensure that it does not shift or deform during construction. The motor drives the gear to rotate through the control system, thereby driving the slider 3 to move precisely along the slide rail 2. This structure enables high-precision positioning under electric control, meeting the needs of automated construction.

[0028] The slider 3 is movably mounted on the slide rail 2 and is used to drive the ball screw 4 for precise positioning in a plane. The shape of the slider 3 matches the slide rail 2, and it has a drive gear inside that mates with the slide rail 2. Its surface is smoothed to reduce friction. The slider 3 can be made of copper alloy, which has good wear resistance and self-lubricating properties, or it can be made of engineering plastic to reduce cost and noise.

[0029] Two adjacent and parallel ball screws 4 form a group. These two groups of ball screws 4, arranged perpendicularly to each other, are connected to two opposing sliders 3, forming a two-dimensional moving platform. The ball screws 4 are controlled by a motor; their rotation controls the movement of the base 5 in the horizontal and vertical directions. The motor can be a stepper motor (inexpensive) or a servo motor (high precision). The two groups of ball screws 4 are perpendicular to each other in space, meaning they do not intersect in the same plane. This structure allows the base 5 to move to any position within the two-dimensional plane.

[0030] The base 5 is installed at the spatial intersection of two sets of ball screws 4, with the ball screws 4 passing directly through the base 5. A hole is located at the center of the base 5 for mounting construction tools. The base 5 can be a circular or square block structure. Internal threads are provided on the inner wall of the hole for threaded connection with the mounting end of the construction tool, ensuring a secure installation.

[0031] The specific description details the combination logic and effects of all components of the device. Frame 1, mounted on the wall, provides a reference. Slide rail 2 and slider 3 cooperate to allow the screw system to move within the plane of frame 1. Two mutually perpendicular ball screws 4 form a two-dimensional moving platform. A motor controls the screws to drive the slider 3, thereby precisely controlling the position of base 5. Construction tools are installed on base 5. By controlling the movement of the screws, precise construction of the tools on the wall can be achieved, ensuring the uniformity, continuity, and thickness of the phosphogypsum spray, thus improving the construction quality of the wall.

[0032] Specifically, the hole in the center of base 5 can be used to install two different construction tools to achieve both spraying and plastering functions.

[0033] When performing the shotcrete function, phosphogypsum spray pipes are installed in the holes to spray phosphogypsum slurry onto the wall. The spray pipes are fixed in the holes of the base 5 by threaded connections to ensure a tight connection and prevent slurry leakage. The motor drives the ball screw 4 to rotate, causing the base 5 to move in the horizontal and vertical planes, and the spray pipes move accordingly; alternatively, the motor can control the rotation of the gear rack on the slide rail 2 to move the slider 3 in the horizontal and vertical planes, thus moving the base 5 and spraying the phosphogypsum slurry onto the wall, achieving uniform, continuous, and constant-thickness shotcrete construction.

[0034] When plastering is performed, a lifting screw 6 is installed in the hole, and a plastering disc 61 is fixed to the end of the lifting screw 6 facing the wall. The lifting screw 6 is raised and lowered via a control shaft 62, which can be electrically or manually controlled. The control shaft 62 has a gear and rack structure. In electric control, the motor drives the gear to rotate, which in turn moves the rack up and down, thereby raising and lowering the lifting screw 6. In manual control, the lifting screw 6 is raised and lowered by turning a manual crank. The plastering disc 61 is a circular or polygonal disc structure with a chamfered edge on the side facing the wall for easy surface smoothing.

[0035] The implementation principle of this embodiment is as follows: The device is installed on the wall through a frame 1 to form a reference plane. The slide rail 2, slider 3, and lead screw system work together to achieve precise positioning of the construction tools in the plane. During the construction process, different construction tools are installed in the holes of the base 5 according to different construction stages. By controlling the movement of the lead screw and the raising and lowering of the lifting lead screw 6, the thickness of the sprayed grout and the flatness of the plaster can be precisely controlled, improving the quality and efficiency of wall construction and solving the problems of low precision, low efficiency, and unstable quality of traditional construction methods.

[0036] Example 2 like Figure 3-5 As shown, compared with Embodiment 1, the difference in this embodiment is that the frame adopts a telescopic structure and the slide rail is composed of segmented splicing to adapt to the construction needs of walls of different sizes and improve the flexibility and applicability of the device.

[0037] Specifically, the retractable frame structure consists of four sets of profile members 7, each including a fixed section 71 and a movable section 72, with length adjustment achieved through a sliding fit. The movable section 72, made of hollow square steel, is embedded inside the fixed section 71. The fixed section 71 has evenly spaced locking holes 711 on its sides for inserting locking bolts. The profile member 7 is fixed with locking bolts. The end of the fixed section 71 has a connecting hole 712 for fastening. Both the fixed section 71 and the movable section 72 of the profile member 7 are equipped with scales for precise adjustment of the frame size according to the wall dimensions. The profile members 7 are connected by corner connectors 8, which have internal slots 81 that insert into the end of the fixed section 71 and are fastened with bolts. The corner connector 8 has multiple symmetrically distributed connecting holes 712, with an adjustment connecting hole 712 at the center. The height of the corner connector 8 can be adjusted using adjusting bolts.

[0038] Specifically, the slide rail adopts a segmented design, which is spliced ​​according to the actual length of the telescopic frame. The two ends of the segmented slide rail are respectively provided with positioning pins and positioning holes. During splicing, the positioning pins are used to align the slide rails. The slide rails on the fixed section 71 are fixed to the fixed section 71 by countersunk bolts. The slide rails on the movable section 72 are fixed to the movable section 72 by pads 9 and countersunk bolts. The thickness of the pads 9 is the same as the thickness of the fixed section 7. The pads 9 eliminate the height difference between the fixed section 71 and the movable section 72 of the profile rod 7.

[0039] The implementation principle of this embodiment is as follows: First, the corner connector 8 is fixed to the wall. Then, the fixed section 71 is inserted into the corner connector 8 and tightened with bolts. Next, the length of the movable section 72 is adjusted to form an adjustable reference plane. The segmented slide rail is spliced ​​together with the expansion and contraction of the frame, and works with the slider and ball screw to drive the base to move in the plane. Through the coordinated action of the telescopic frame and the segmented slide rail, it can adapt to the construction of walls of different sizes.
