Description

Technical Field

[0001] This utility model relates to a rapid wall roughening device, belonging to the field of building construction engineering technology. Background Technology

[0002] The newly built Shenyang-Baihe Railway, located in the southern parts of Liaoning and Jilin provinces in Northeast China, is a regional connecting line of the "Eight Vertical and Eight Horizontal" high-speed railway network. It is of great significance for promoting the comprehensive revitalization of Northeast China and achieving high-quality regional economic development. In the construction of the electrical and electronic buildings along the Shenyang-Baihe High-Speed ​​Railway, surface preparation (or roughening) is an indispensable part of the building construction, and its quality directly affects the overall effect and quality of the building. This process not only affects the aesthetics of the walls but also the structural safety and service life of the building. Therefore, it is essential to strictly control the surface preparation process to ensure that its quality meets standards, thereby guaranteeing the stability and durability of the building. Therefore, improving the overall construction effect of surface preparation has become a key focus of the current construction. The Second Engineering Company of China Railway Electrification Bureau Group, based on the Shenyang-Baihe High-Speed ​​Railway project, conducted an investigation and research on the surface preparation process and found that the main reasons for poor surface preparation quality lie in the surface preparation methods and tools used. Currently, there are generally three methods for roughening the surface: First, using a roughening machine to create numerous grooves on the wall. This method requires skill and experience, is complex and difficult to implement, and is slow. Second, using a roughening broom dipped in cement slurry to pat the wall surface, allowing the cement to penetrate and create raised dots. This method is inefficient, the roughening quality varies greatly from person to person, and it is prone to material waste. Third, high-pressure water roughening uses ultra-high-pressure water jets to directly create many deep grooves on the wall surface. This method is costly. Therefore, there is a need to develop a device that is simple to operate, provides high-quality roughening, and is low-cost. Utility Model Content

[0033] The present invention provides the following embodiments.

[0034] like Figure 1 , Figure 2 As shown, this utility model discloses a rapid wall roughening device, comprising a base 1, a pump 2, a slurry storage hopper 3, a flexible pipe 4, a rigid pipe 5, and a roughening roller 6. The pump 2 and the slurry storage hopper 3 are disposed within the base 1, and the slurry storage hopper 3 is connected to the pump 2. The outlet of the pump 2 is connected to the lower end of the flexible pipe 4. The pump 2 provides power for conveying mortar, the slurry storage hopper 3 is used to store mortar, and the flexible pipe 4 serves to convey mortar and assist in adjusting the roughening working direction.

[0035] like Figure 3As shown, the rigid tube 5 is an L-shaped hollow tube, including a vertical tube part 51 and a horizontal tube part 52. The lower end of the vertical tube part 51 is connected to the upper end of the flexible tube 4, and the upper end of the vertical tube part 51 is connected to one end of the horizontal tube part 52. The other end of the horizontal tube part 52 is closed. The rigid tube 5 is designed to convey mortar and facilitate hand handling.

[0036] The texturing roller 6 is mounted on the horizontal tube section 52 and rotatably connected via rotating bearings 7. Both ends of the horizontal tube section 52 are threaded with nuts 8, which are respectively pressed against the outer sides of the two rotating bearings 7. One or more elongated holes 53 are formed in the tube body inside the texturing roller 6 on the horizontal tube section 52. These elongated holes 53 facilitate the flow of mortar into the texturing roller 6. The texturing roller 6 is rotatable and is the main working component. The two nuts 8 provide limiting constraints to the texturing roller 6, ensuring its secure connection to the horizontal tube section 52.

[0037] like Figure 4 , Figure 5 , Figure 6 As shown, the grouting roller 6 includes a roller 61, a sealing cover 62, and a conical slurry outlet 63. The roller 61 is a round tube open at both ends, with multiple mounting holes 64 evenly distributed on it. Multiple conical slurry outlets 63 are fixed in the mounting holes 64 one by one. Two sealing covers 62 are respectively installed at both ends of the roller 61 by threads. The center of the sealing cover 62 is provided with an inward groove, and the center of the groove has a hole that matches the horizontal tube part 52. The rotating bearing 7 is installed in the groove. The roller 61 serves to store mortar, and the sealing cover 62 serves to seal both ends of the roller 61 to prevent mortar from overflowing.

[0038] like Figure 7 , Figure 8 As shown, the outer shell 631 of the conical slurry outlet 63 is composed of a conical tube and a cylindrical tube. The top of the conical tube is the slurry outlet 632. The spring seat 633 is located on the central axis of the cylindrical tube. The spring seat 633 is connected to the bottom of the outer shell 631 by multiple connecting strips. The lower end of the compression spring 634 is located in the spring seat 633, and the upper end is fixedly connected to one side of the circular slurry blocking disc 635. The other side of the slurry blocking disc 635 is vertically fixed with a striking pin 636. The striking pin 636 extends out of the slurry outlet 632, and the diameter of the striking pin 636 is smaller than the inner diameter of the slurry outlet 632.

[0039] The conical slurry outlet 63 is the main slurry outlet channel. The compression spring 634 restricts the static position of the slurry blocking disc 635 and the impact pin 636, so that the slurry blocking disc 635 is pressed against the conical tube part of the outer shell 631, blocking the slurry outlet 632. The compression spring 634 also provides a reverse force for the slurry blocking disc 635 and the impact pin 636 when they return to their original position.

[0040] The vertical tube portion 51 of the rigid tube 5 is a telescopic tube.

[0041] The base 1 is equipped with multiple casters 9. The casters 9 facilitate the movement of the base 1.

[0042] A handle 10 is installed on the base 1. The handle 10 makes it easy to lift the base 1.

[0043] The conical slurry outlet 63 is connected to the mounting hole 64 by a thread or by adhesive.

[0044] The flexible tube 4 is a plastic corrugated tube.

[0045] A gasket is provided between the rotary bearing 7 and the nut. The gasket protects the rotary bearing.

[0046] Pump 2 is a pressure-stabilizing pump.

[0047] In this invention, the compression spring 634, the slurry blocking disc 635, and the striking pin 636 are all made of Q235 medium carbon steel, which features high strength, good toughness, and good oxidation resistance. The flexible pipe 4 is made of PA nylon corrugated pipe, which features high toughness, impact resistance, good bending performance, high temperature resistance, friction resistance, chemical corrosion resistance, and good flame retardancy. The rigid pipe 5, gasket, and outer shell 631 are made of aluminum alloy, which features high strength and light weight, and has high properties in terms of castability, corrosion resistance, and weldability. The roller 61 and the sealing cover 62 are made of polypropylene plastic, which has low density, strong heat resistance, and good hardness, firmness, and strength. The above materials have good stability during operation and are very suitable as materials for the above parts.

[0048] Before manufacturing this utility model, the power of pump 2 is determined to provide a basis for the design of this utility model. The installation steps of this utility model are as follows:

[0049] All components are neatly arranged. First, connect the outlet of pump 2 to one end of flexible tube 4, and then connect the other end of flexible tube 4 to the lower end of rigid tube 5. Then, install the rotating bearing 7 in the groove of sealing cover 62. Sealing cover 62 is installed at both ends of roller 61 by threads. Next, install the impact pin 636, slurry blocking disc 635 and compression spring 634 in the outer shell 631 to assemble multiple conical slurry outlets 63. Then, install the conical slurry outlets 63 one by one into the mounting holes 64 on roller 61 to assemble the sizing roller 6. Then, install the nut 8, washer, sizing roller 6, washer and nut 8 in sequence on the horizontal tube part 52 of rigid tube 5. The assembly of this utility model is then completed.

[0050] The method of using this utility model is as follows: Before the roughening work, check whether the roughening roller 6 and other components are normal. After the check is completed, connect the power supply and start the pump 2. The mortar flows out from the mortar storage hopper 3, passes through the flexible pipe 4 and enters the rigid pipe 5. Then it flows out from the elongated hole 53 on the horizontal pipe section 52 and enters the roughening roller 6. Press the roughening roller 6 against the wall and roll it to perform pre-roughening treatment. After the mortar output is stable, operate the rigid pipe 5 to drive the roughening roller 6 to roll regularly on the wall surface, so that the impact pin 636 that is in contact with the wall surface is pressed back, the mortar blocking plate 635 separates from the outer shell 631, and the mortar in the roller 61 flows from the mortar outlet 632 to the wall surface, thereby completing the roughening work. After the impact pin 636 leaves the wall surface as it rotates, under the action of the compression spring 634, the mortar blocking plate 635 is pressed back onto the outer shell 631, re-sealing the mortar outlet 632 and avoiding the waste of mortar.

[0051] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
