Description

Technical Field

[0001] This utility model relates to the field of building equipment technology, and in particular to a wall plaster thickness control device. Background Technology

[0002] Wall plastering can isolate external moisture and dust, extending the lifespan of the wall. It can fill in unevenness in the wall, providing a smooth base for subsequent decoration (such as tiling and painting). Additional functions such as insulation and fireproofing can be achieved by adding special materials (such as insulating and fireproof mortar). Plastering equipment is frequently used in construction projects and home renovations.

[0003] In the wall plastering stage of building construction, ensuring plastering quality and construction efficiency is crucial. A plastering device for adjusting the coating thickness, as described in Publication No. CN217631083U, while offering some assistance to the plastering operation, still has significant drawbacks. In this solution, leveling components such as the material storage box relies entirely on manual operation. In actual construction scenarios, complex ground conditions and uneven surfaces are common, making leveling the material storage box extremely difficult. The weight of the storage box increases significantly after being loaded with material; a fully loaded storage box can weigh tens of kilograms or even more. This not only makes it difficult for workers to grip and precisely control the leveling action but also easily leads to worker fatigue, reducing both the accuracy and efficiency of leveling. Poor leveling of the storage box results in uneven plaster thickness, causing inconsistent wall thickness and severely affecting the flatness and aesthetics of the wall, requiring additional manpower and time for subsequent repairs. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a wall plaster thickness control device.

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

[0006] A wall plaster thickness control device includes a storage box and a fixing frame. The storage box is equipped with a T-shaped rod via a cylinder. The fixing frame is equipped with lifting screws via a rotating groove. The fixing frame has a transmission chamber inside. The ends of two lifting screws extend into the transmission chamber and are connected by a synchronization mechanism. The transmission chamber is equipped with an internal motor connected to one of the lifting screws. The two lifting screws are threaded together and fitted with a lifting frame. The storage box is fixedly equipped with multiple mounting plates. The lifting frame is equipped with annular grooves corresponding to the mounting plates. One of the mounting plates is equipped with an external motor, which is connected to the lifting frame via a meshing mechanism.

[0007] Preferably, the synchronization mechanism includes synchronous pulleys fixedly mounted on two lifting screws, and the two synchronous pulleys are connected by a synchronous belt.

[0008] Preferably, the meshing mechanism includes a gear fixedly mounted on the output shaft of the external motor, and an internal gear ring that meshes with the gear is fixedly mounted on the lifting frame.

[0009] Preferably, a limiting rod is provided in the rotating groove, and the limiting rod is vertically arranged and slides through the lifting frame.

[0010] Preferably, the lifting frame is provided with multiple disassembly ports, each of which corresponds to the mounting plate and communicates with the annular groove.

[0011] Preferably, there are four mounting plates and four disassembly ports, and the four mounting plates and disassembly ports are distributed at equal intervals around the circumference.

[0012] The beneficial effects of this utility model are:

[0013] 1. Driven by the lifting screw and internal motor, the storage box can move up and down to cover walls of different heights without the need for manual scaffolding or climbing, thus improving plastering efficiency and reducing safety risks.

[0014] 2. The external motor, in conjunction with the gear and internal gear ring transmission, allows the storage box to rotate and level relative to the lifting frame, avoiding uneven plaster thickness caused by the tilt of the fixed frame and ensuring construction accuracy.

[0015] 3. The circumferentially staggered snap-fit ​​structure of the mounting plate and the disassembly port allows for quick disassembly and assembly of the storage box. During maintenance, components can be separated without tools, reducing downtime for maintenance and improving equipment utilization.

[0016] 4.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-3 A wall plastering thickness control device includes a storage box 1 and a fixing frame 4. A T-shaped rod 2 is provided on the storage box 1 via a cylinder 3. A pressure plate (not shown in the figure) is provided inside the storage box 1, which can squeeze the material inside the storage box 1 through the discharge port (not shown in the figure) to the wall surface to realize the plastering operation.

[0023] The fixed frame 4 is equipped with lifting screws 5 that are mounted through a rotating groove. The fixed frame 4 has a transmission chamber 13 inside. The ends of the two lifting screws 5 extend into the transmission chamber 13 and are connected by a synchronization mechanism. The transmission chamber 13 is equipped with an internal motor 15 that is connected to one of the lifting screws 5. The lifting screw 5 is installed in the rotating groove using mature equipment components such as bearing seats. The outer wall of the part inside the transmission chamber 13 is not threaded, and it is connected to the output shaft of the internal motor 15 by a coupling. Based on the above, which are all basic common sense in the mechanical field, the specific structure is not disclosed in this solution.

[0024] A lifting frame 6 is threadedly installed between two lifting screws 5. The storage box 1 is fixedly provided with multiple mounting plates 8. The lifting frame 6 is provided with an annular groove 7 corresponding to the mounting plate 8. An external motor 10 is provided on one of the mounting plates 8. The external motor 10 is connected to the lifting frame 6 through a meshing mechanism, so that the storage box 1 can be rotatably installed in the annular groove 7.

[0025] Furthermore, the synchronization mechanism includes a synchronous pulley 16 and a synchronous belt 17; the two synchronous pulleys 16 are respectively disposed at the ends of the two lifting screws 5 located in the transmission chamber 13; the two synchronous pulleys 16 are connected by the synchronous belt 17. Due to the synchronous pulleys 16 and the synchronous belt 17, when the internal motor 15 drives the directly connected lifting screw 5 to rotate, the other lifting screw 5 can rotate synchronously.

[0026] Furthermore, the meshing mechanism includes a gear 11 fixedly mounted on the output shaft of the external motor 10, and an internal gear ring 12 meshing with the gear 11 fixedly mounted on the lifting frame 6. The external motor 10 drives the gear 11 to rotate, thereby causing the gear 11 to rotate along the internal gear ring 12. Specifically, due to the presence of the external motor 10 and the gear 11, when the external motor 10 is powered on and drives the gear 11 to rotate, the storage box 1 and other components can rotate relative to the lifting frame 6. This allows the storage box 1 to be adjusted to a horizontal state when the ground is uneven.

[0027] Furthermore, a limiting rod 14 is provided inside the rotating groove. The limiting rod 14 is vertically arranged and slides through the lifting frame 6. The function of the limiting rod 14 is to limit the lifting frame 6 and prevent it from rotating with the lifting screw 5.

[0028] Furthermore, the lifting frame 6 is provided with multiple disassembly ports 9, each corresponding to a different mounting plate 8, and the disassembly ports 9 are connected to the annular groove 7. In some embodiments, there are four mounting plates 8 and four disassembly ports 9, which are circumferentially evenly distributed. In the installed state, the four mounting plates 8 and the four disassembly ports 9 are staggered. When the mounting plate 8 moves to correspond with the disassembly port 9, the fixing frame 4 and the lifting frame 6 can be easily detached from the mounting plates 8 and the storage box 1, facilitating routine maintenance or parts replacement of the storage box 1 and other components.

[0029] Components not specifically described in this utility model are all standard parts and can be purchased from the market. The specific connection methods for each component all employ mature methods from the prior art, and will not be detailed here. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0030] When this utility model is in use, the internal motor 15 starts and drives one lifting screw 5 to rotate. The synchronous pulley 16 and the synchronous belt 17 make the other lifting screw 5 rotate synchronously. The lifting frame 6 is threaded on the screw and is restricted from rotating by the limiting rod 14, so it moves up and down along the limiting rod 14 to realize the height adjustment of the storage box 1 and adapt to the plastering needs of walls of different heights.

[0031] When the ground is uneven, the fixed frame 4 is in a tilted state. At this time, the external motor 10 starts, and the output shaft drives the gear 11 to rotate, which meshes with the internal gear ring 12 on the lifting frame 6, causing the storage box 1 to rotate around the annular groove 7. The level instrument is used to detect and monitor whether the storage box 1 is in a horizontal state, thereby ensuring that the plastering thickness is uniform.

[0032] In addition, the storage box 1 is connected to the annular groove 7 of the lifting frame 6 via the mounting plate 8. During normal operation, the mounting plate 8 is offset from the disassembly port 9. When maintenance is required, the storage box 1 is rotated so that the mounting plate 8 is aligned with the disassembly port 9, and the storage box 1 can be separated from the lifting frame 6 for easy replacement or cleaning of parts.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
