Description

Technical Field

[0001] This invention relates to building wall construction equipment, specifically to an automated wall slurry application equipment. Background Technology

[0002] Applying mortar is an important step before plastering walls. A mortar application tool is used to apply a certain proportion of cement mortar to the wall surface, increasing the adhesion between the wall surface and the plaster layer, thus bonding them together. The quality of the mortar application directly affects the final finish of the wall surface. Substandard mortar application can lead to a series of quality problems such as bubbles, hollow areas, and peeling.

[0003] Currently, most wall plastering operations use simple tools such as brooms and wire mesh shovels. Workers repeatedly swing the shovel to complete the plastering process, resulting in low efficiency and inconsistent quality. Furthermore, the repeated dipping of the shovel into the plaster causes dripping, polluting the environment and wasting resources. While some improvements have been proposed and some wall plastering devices have been disclosed, existing devices still suffer from the following problems: 1) Inconvenient plaster addition, requiring multiple dipping; 2) Insufficient automation, resulting in low plastering quality and efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an automated wall slurry application device. This device realizes automatic lifting, slurry application, and slurry replenishment of the slurry application device, which has high operating efficiency, good construction quality, avoids multiple dipping of slurry, can adapt to wall inclination, and meets the requirements of slurry application on inclined walls.

[0005] The technical solution adopted in this invention is:

[0006] An automated wall grouting device includes a traveling trolley, on which are mounted a grouting device, a lifting frame, a lifting mechanism, a pressure pump, a grout storage tank, and a control system. The rear end of the grouting device is slidably mounted on the lifting frame, the middle part is a transmission module, and the front end is a grouting box for holding grout. The front face of the grouting box is a grouting plate with grout outlet holes distributed on it. The transmission module drives the grouting box to reciprocate back and forth and enables the grouting box to adapt to the tilt of the wall and return to its original position. The lifting mechanism drives the grouting device to move up and down on the lifting frame. The pressure pump pressurizes and delivers the grout stored in the storage tank to the grouting box. The control system controls the grouting device, the lifting mechanism, and the pressure pump, so that during operation, the lifting mechanism drives the grouting device to move up and down within the construction area, the grouting device grouts evenly and completely during the lifting process, and the pressure pump replenishes the grouting device with grout.

[0007] Preferably, the transmission module includes a telescopic mechanism, a balance spring, and a ball joint seat. The telescopic mechanism can reciprocate back and forth. The movable end of the telescopic mechanism is connected to the middle position of the rear end face of the slurry box through the ball joint seat. The balance spring is connected to the rear end face of the slurry box and distributed around the telescopic mechanism.

[0008] Preferably, the telescopic mechanism includes a fixed cylinder, a movable cylinder, a motor, a rotating shaft, and a return spring. The fixed cylinder and the movable cylinder are nested together and can only move relative to each other in the axial direction. The motor drives the rotating shaft to rotate, and the rotating shaft extends into the fixed cylinder and the movable cylinder. The portion of the rotating shaft inside the fixed cylinder is fitted with a return spring, and the portion inside the movable cylinder has a helical protrusion on its outer circumference. The return spring axially abuts against the movable cylinder, and the movable cylinder has a protrusion corresponding to the helical protrusion. When the movable cylinder extends forward to its front limit position, the helical protrusion contacts the corresponding protrusion on its rearward side. Then, the motor drives the rotating shaft to rotate, and the helical protrusion drives the protrusion to move backward, thereby causing the movable cylinder to retract backward and compress the return spring. When the movable cylinder reaches its rear limit position, the protrusion leaves the helical protrusion, and then the return spring quickly returns to its original position and pushes the movable cylinder forward to its front limit position.

[0009] Preferably, the lifting frame adopts a two-stage guide rail. The first-stage guide rail is fixed, and the second-stage guide rail is slidably installed on the first-stage guide rail. The rear end of the propeller is slidably installed on the second-stage guide rail. Before rising, the second-stage guide rail is folded onto the first-stage guide rail. When rising, the propeller first rises along the second-stage guide rail. After reaching the top of the second-stage guide rail, the propeller extends upward along the first-stage guide rail until it reaches the upper limit position.

[0010] Preferably, the lifting device includes a winch, a wire rope, a hanging point, and pulleys one through six. The winch is fixedly mounted on the traveling trolley. Pulley one is located at the top of the primary guide rail. Pulleys two and three are arranged side by side at the bottom of the secondary guide rail. Pulley four and the hanging point are located at the top of the secondary guide rail. Pulleys five and six are arranged side by side at the rear end of the propeller. One end of the wire rope is connected to the winch, and the other end passes through pulleys one through six in sequence before connecting to the hanging point. The propeller has limiting structures at the upper and lower limit positions of the secondary guide rail, and the secondary guide rail has limiting structures at the upper and lower limit positions of the primary guide rail.

[0011] Preferably, the winch is equipped with a bending moment sensor. The bending moment sensor measures the maximum and minimum values ​​at the upper and lower limit positions of the slurry ejector, respectively. The higher the slurry ejector, the larger the measured value of the bending moment sensor. Before operation, the lower and upper positions of the slurry ejector are determined according to the height range of the construction area, and the corresponding measured values ​​are obtained. During operation, when the control system receives the measured value signal corresponding to the lower position, it drives the slurry ejector to rise in the reverse direction; when it receives the measured value signal corresponding to the upper position, it drives the slurry ejector to descend in the reverse direction.

[0012] Preferably, both the primary and secondary guide rails adopt a frame structure, with the two sides of the secondary guide rail embedded in the inner sides of the primary guide rail, and the two sides of the rear end of the propeller embedded in the inner sides of the secondary guide rail. The secondary guide rail is in line contact with the primary guide rail, and the rear end of the propeller is in rolling contact with the secondary guide rail.

[0013] Preferably, during operation: the lifting device drives the slurry ejector to move continuously or step by step, and the slurry ejector throws out the slurry plate one after another from top to bottom or from bottom to top. The positions of two adjacent throws of the slurry plate are exactly staggered vertically, so as to fully cover the construction area of ​​the current position of the traveling trolley with slurry; then the slurry plate stops throwing out the slurry, and the traveling trolley is moved to the next position by manual pushing or automatic control; then the slurry plate throws out the slurry plate one after another in the opposite direction; the above steps are repeated until all construction areas are fully covered.

[0014] Preferably, the pressure pump is connected to the grouting box through the grouting pipe, and the traveling trolley is equipped with a storage rack for winding and storing the grouting pipe.

[0015] Preferably, the slurry outlet is a conical hole with a larger inner diameter and a smaller outer diameter.

[0016] The beneficial effects of this invention are:

[0017] This equipment enables automatic lifting, slurry application, and slurry replenishment of the slurry applicator, resulting in high operational efficiency and excellent construction quality. It avoids the need for multiple slurry dipping operations, adapts to wall inclination, and meets the requirements for slurry application on inclined walls. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0039] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0040] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0041] The features and performance of this application will be further described in detail below with reference to the embodiments.

[0042] like Figures 1 to 11As shown, this embodiment discloses an automated wall grouting device, including a traveling trolley 1, on which a grouterer 2, a lifting frame 3, a lifting device 4, a pressure pump 5, a grout storage tank 6, and a control system are mounted. The rear end of the grouterer 2 (via a crossbeam 21) is slidably mounted on the lifting frame 3, the middle part is a transmission module, and the front end is a grouting box 23 for containing grout. The front end face of the grouting box 23 is a grouting plate 24, on which grout outlet holes 241 are distributed. The transmission module is used to drive the grouting box 23 to vibrate back and forth and to enable the grouting box 23 to adapt to the tilt of the wall and return to its original position. The lifting device 4 is used to drive the grouterer 2 to rise and fall on the lifting frame 3. The pressure pump 5 is used to pressurize and transport the grout stored in the grout storage tank 6 to the grouting box 23. The control system is used to control the grouterer 2, the lifting device 4, and the pressure pump 5, so that during operation, the lifting device 4 drives the grouterer 2 to rise and fall within the construction area, the grouterer 2 grouts evenly and completely during the rising and falling process, and the pressure pump 5 replenishes the grouterer 2 with grout. This equipment enables automatic lifting, slurry application, and slurry replenishment of the slurry applicator 2, resulting in high operational efficiency and good construction quality. It avoids the need for multiple slurry dipping operations, can adapt to wall inclination, and meets the requirements for slurry application on inclined walls.

[0043] During operation: The lifting device 4 drives the slurry ejector 2 to move continuously or stepwise. The slurry ejector 2 ejects slurry sequentially from top to bottom or from bottom to top. The ejection positions of the slurry ejector plate 24 are staggered vertically between adjacent ejection positions, thereby completely covering the construction area of ​​the current position of the traveling trolley 1 with slurry. Then the slurry ejector plate 24 stops ejecting slurry, and the traveling trolley 1 is manually pushed or automatically controlled to move to the next position. Then the slurry ejector plate 24 ejects slurry sequentially in the opposite direction. The above steps are repeated until all construction areas are completely covered. Finally, all construction areas can be inspected, and secondary slurry ejection can be performed on areas that have not been properly slurried to ensure that all areas are properly slurried.

[0044] like Figures 1 to 5 As shown, preferably, the lifting frame 3 adopts a two-stage guide rail. The first-stage guide rail 31 is fixed, and the second-stage guide rail 32 is slidably installed on the first-stage guide rail 31. The rear end of the slurry ejector 2 is slidably installed on the second-stage guide rail 32. Before rising, the second-stage guide rail 32 is folded onto the first-stage guide rail 31. When rising, the slurry ejector 2 first rises along the second-stage guide rail 32. After reaching the top of the second-stage guide rail 32, the slurry ejector 2 extends upward along the first-stage guide rail 31 until it reaches the upper limit position. The lifting frame 3 adopts a two-stage foldable structure, which is suitable for storage and turnover and adapts to narrow construction occasions.

[0045] like Figures 1 to 5As shown, preferably, the lifting device 4 includes a winch 47, a wire rope 48, an attachment point 49, and pulleys one to six (41 to 46). The winch 47 is fixedly installed on the traveling trolley 1. Pulley one 41 is located at the top of the primary guide rail 31. Pulley two 42 and pulley three 43 are arranged side by side at the bottom of the secondary guide rail 32. Pulley four 44 and attachment point 49 are located at the top of the secondary guide rail 32. Pulley five 45 and pulley six 46 are arranged side by side at the rear end of the shovel 2. The wire rope 48... One end is connected to the winch 47, and the other end passes through pulleys one to six (41 to 46) in sequence before connecting to the hanging point 49; the slurry ejector 2 is equipped with limit structures 33 at the upper and lower limit positions of the secondary guide rail 32 and the upper and lower limit positions of the secondary guide rail 32 at the primary guide rail 31; the lifting device 4 achieves transmission by the winch 47 winding and unwinding the wire rope 48, and guides the force transmission path of the wire rope 48 through pulleys one to six (41 to 46), which is convenient to install and has a simple structure.

[0046] like Figure 2 As shown, preferably, the winch 47 is equipped with a bending moment sensor 471. The measured values ​​of the bending moment sensor 471 at the upper and lower limit positions of the slurry ejector 2 are the maximum and minimum values, respectively. The higher the slurry ejector 2 is, the larger the measured value of the bending moment sensor 471 is. Before operation, the lower and upper positions of the slurry ejector 2 are determined according to the height range of the construction area, and the corresponding measured values ​​are obtained. During operation, when the control system receives the measured value signal corresponding to the lower position, it drives the slurry ejector 2 to rise in the reverse direction; when it receives the measured value signal corresponding to the upper position, it drives the slurry ejector 2 to descend in the reverse direction. This setting can flexibly control the lower and upper positions of the slurry ejector 2 according to the height range of the construction area, and the operation is simple.

[0047] like Figures 1 to 6 As shown, preferably, both the primary guide rail 31 and the secondary guide rail 32 adopt a frame structure. The two sides of the secondary guide rail 32 are respectively embedded in the inner sides of the primary guide rail 31, and the two sides of the rear end of the propeller 2 are respectively embedded in the inner sides of the secondary guide rail 32. The secondary guide rail 32 is in line contact with the primary guide rail 31, and the rear end of the propeller 2 is in rolling contact with the secondary guide rail 32 (through roller 211), so the transmission is stable and reliable.

[0048] like Figures 1 to 2 As shown, preferably, the pressure pump 5 is connected to the grouting box 23 through the grouting pipe 7, and the traveling trolley 1 is equipped with a storage rack 11 for winding and storing the grouting pipe 7. When not in use, the grouting pipe 7 can be wound and stored on the storage rack 11 to avoid the grouting pipe 7 from getting tangled and blocked.

[0049] like Figure 2 As shown, preferably, the slurry storage tank 6 is provided with an openable and closable slurry inlet 12, allowing the prepared slurry to be directly added through the slurry inlet 12, or the slurry to be prepared directly inside the slurry storage tank 6. Figure 2As shown, preferably, the traveling wheels of the traveling trolley 1 are swivel wheels 13. Figure 2 As shown, preferably, the slurry storage tank 6 is rectangular. Figure 2 As shown, preferably, the trolley 1 is equipped with a pusher 14 to facilitate the movement of the whole unit by on-site personnel.

[0050] like Figures 7 to 9 As shown, preferably, the transmission module includes a telescopic mechanism 221, a balance spring 222, and a ball joint seat 223. The telescopic mechanism 221 can reciprocate back and forth. The movable end of the telescopic mechanism 221 is connected to the middle position of the rear end face of the slurry box 23 through the ball joint seat 223. The balance spring 222 is connected to the rear end face of the slurry box 23 and distributed around the telescopic mechanism 221. The reciprocating extension and retraction of the telescopic mechanism 221 drives the slurry box 23 to vibrate back and forth. The ball joint seat 223 enables the slurry box 23 to adapt to the tilt of the wall (the ball joint seat 223 can rotate within a certain range. When the slurry plate 24 extends and contacts the tilted wall, the slurry plate 24 will fit against the tilted wall). The balance spring 222 enables the slurry box 23 to return to its original position after tilting (the tilted state of the slurry box 23 will cause some of the balance springs 222 to be under tension and some under compression. When it leaves the wall, the slurry box 23 returns to its normal state under the action of the balance spring 222). It also provides a certain restoring force for the slurry box 23.

[0051] like Figures 7 to 9 As shown, the rear of the telescopic mechanism 221 is installed inside the power box 25, and the power box 25 is installed on the frame 26.

[0052] like Figure 9 As shown, preferably, the slurry outlet 241 is a conical hole with a larger inner diameter and a smaller outer diameter, which provides a good slurry throwing effect.

[0053] like Figures 10 to 11As shown, preferably, the telescopic mechanism 221 includes a fixed cylinder 2212, a movable cylinder 2211, a motor 2213, a rotating shaft 2214, and a return spring 2215; the fixed cylinder 2212 and the movable cylinder 2211 are sleeved together and can only move relative to each other in the axial direction; the motor 2213 is used to drive the rotating shaft 2214 to rotate; the rotating shaft 2214 extends into the fixed cylinder 2212 and the movable cylinder 2211; the portion of the rotating shaft 2214 inside the fixed cylinder 2212 is fitted with the return spring 2215, and the portion inside the movable cylinder 2211 has a helical protrusion 2216 on its outer circumference; the return spring 2215 axially abuts against the movable cylinder 2211. The movable cylinder 2211 has a protrusion 2217 corresponding to the spiral protrusion 2216. When the movable cylinder 2211 extends forward to its front limit position, the spiral protrusion 2216 contacts the corresponding protrusion 2217 on its rearward side. Then, the motor 2213 drives the rotating shaft 2214 to rotate, and the spiral protrusion 2216 drives the protrusion 2217 to move backward, thereby causing the movable cylinder 2211 to retract backward and compress the return spring 2215. When the movable cylinder 2211 reaches its rear limit position, the protrusion 2217 leaves the spiral protrusion 2216, and then the return spring 2215 quickly returns to its original position and pushes the movable cylinder 2211 forward to its front limit position. This telescopic mechanism 221 can achieve smooth backward movement and rapid forward movement of the slurry box 23, resulting in good slurry throwing effect.
