Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, and in particular to a cleaning device for the inner wall of a precast wall panel mold. Background Technology

[0002] In the current era of rapid development in industrialized construction, precast wall panels have been widely used in various construction projects due to their significant advantages such as high construction efficiency and controllable quality. The production of precast wall panels relies on molds, and the cleanliness of the mold's inner wall plays a decisive role in the molding quality of the precast wall panels. If impurities such as concrete and dirt remain on the mold's inner wall, it will lead to quality defects such as pitting and honeycombing on the surface of the precast wall panels, seriously affecting the appearance quality and mechanical properties of the wall panels, reducing the product's market competitiveness, and even potentially causing engineering safety hazards. Therefore, it is crucial to conduct a thorough and effective cleaning of the inner wall of the precast wall panel mold after each use. Existing precast wall panel mold inner wall cleaning... The existing cleaning devices have a relatively fixed structure and lack a flexible adjustment mechanism. Different construction projects have diverse requirements for the size and shape of precast wall panels, resulting in a wide variety of precast wall panel mold specifications. However, existing cleaning devices can often only adapt to molds of specific sizes or shapes. When faced with molds of different specifications, the cleaning devices cannot be effectively adjusted and adapted. When cleaning large precast wall panel molds, the limited cleaning range of the cleaning devices cannot cover the entire area of ​​the mold's inner wall, resulting in some areas not being thoroughly cleaned. For molds with special structures, such as those with grooves or protrusions, existing cleaning devices have difficulty penetrating into special areas for cleaning, creating cleaning dead spots.

[0003] Therefore, in order to address this problem, this utility model provides a precast wall panel mold inner wall cleaning device. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the prior art by proposing a precast wall panel mold inner wall cleaning device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a precast wall panel mold inner wall cleaning device, comprising a first cleaning nozzle frame, a second cleaning nozzle frame rotatably connected to the side of the first cleaning nozzle frame via a hinge, a fixed seat provided on the side of the first cleaning nozzle frame away from the second cleaning nozzle frame, and a docking seat provided on the side of the second cleaning nozzle frame away from the first cleaning nozzle frame, the tops of the fixed seat and the docking seat being connected by a threaded limit threaded pin, U-shaped frames symmetrically arranged on the sides of the first and second cleaning nozzle frames, a crossbar being snapped between the two U-shaped frames, a positioning threaded rod being threaded between the U-shaped frames and the crossbar, a first mating joint being provided at the midpoint of the positioning threaded rod, a fixed rod being threadedly connected to the surface of the first mating joint, an adjusting rod being threadedly connected to the surface of the fixed rod, an injection valve being provided on the side of the first and second cleaning nozzle frames, and a water pipe mating joint being provided between the two injection valves.

[0006] Preferably, one end of the limiting threaded pin passing through the mating seat is connected to a limiting sleeve via a thread, the limiting sleeve being used to prevent it from falling off.

[0007] Preferably, a handle is fixedly connected to the end of the adjusting rod away from the fixed rod.

[0008] Preferably, a limiting member is fixedly connected to the surface of the fixing rod, and the water pipe connector is threadedly connected to the limiting member.

[0009] Preferably, the injection valve is located in the middle of the first cleaning nozzle frame, and the U-shaped frame does not contact the injection valve.

[0010] Preferably, a second pair of connectors is provided in the middle of the U-shaped frame, and the second pair of connectors is threadedly connected to the fixing rod.

[0011] Compared with the prior art, this utility model provides a precast wall panel mold inner wall cleaning device, which has the following beneficial effects:

[0012] This wall panel mold inner wall cleaning device, through its rotatable first and second cleaning nozzle frames and the flexible threaded connection between the fixing rod and the first and second connectors, can be adaptively adjusted to precast wall panel molds of different sizes and shapes. When cleaning large molds, the two nozzle frames are unfolded and fixed with limiting threaded pins, and the fixing rod is connected to the second connector to expand the cleaning range and ensure that all parts of the mold's inner wall are effectively cleaned. For small molds, the first and second cleaning nozzles can be closed for precise cleaning. For molds with special structures, the connection angle between the fixing rod and the second connector can be adjusted to achieve precise cleaning of specific areas. This highly flexible structural design allows one cleaning device to meet the cleaning needs of various mold sizes, greatly improving the versatility of the cleaning device and reducing the cost investment required for companies to purchase multiple cleaning equipment due to different mold specifications.

[0013] This wall panel mold inner wall cleaning device significantly enhances the overall stability of the cleaning device through the cooperation of the limiting threaded pin and the limiting sleeve, as well as the stable connection structure of the U-shaped frame, the crossbar, and the positioning threaded rod. During the cleaning process, the impact force of high-pressure water and the reaction force of the mold inner wall on the cleaning components will cause the device to vibrate. The limiting sleeve effectively prevents the limiting threaded pin from falling off, ensuring that the first and second cleaning nozzle frames always maintain a stable connection. The firm connection between the U-shaped frame, the crossbar, and the positioning threaded rod enables the device to withstand large reaction forces without deformation or shaking.

[0018] 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.

[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model.

[0020] Reference Figures 1-3A precast wall panel mold inner wall cleaning device mainly consists of a first cleaning nozzle frame 1, a second cleaning nozzle frame 2, a fixed base 3, a docking seat 4, a limiting threaded pin 5, a U-shaped frame 7, a crossbar 8, a positioning threaded rod 9, a first coupling joint 10, a fixed rod 11, an adjusting rod 12, an injection valve 15, and a water pipe coupling joint 16. The first cleaning nozzle frame 1 and the second cleaning nozzle frame 2 are rotatably connected by a hinge. This design gives the device a flexible unfolding and retraction function. When the cleaning device needs to be stored, the operator can easily rotate it. The second cleaning nozzle holder 2 is folded and fitted snugly with the first cleaning nozzle holder 1, greatly reducing the space occupied by the device and facilitating storage and transportation. For example, after the cleaning work is completed, the device can be folded and placed in a corner of the warehouse without taking up too much warehouse space, making it convenient for storing other items. A fixing base 3 is fixedly installed on the side of the first cleaning nozzle holder 1 away from the second cleaning nozzle holder 2, and a docking seat 4 is fixedly installed on the side of the second cleaning nozzle holder 2 away from the first cleaning nozzle holder 1. When the device is in the unfolded state and cleaning the inner wall of the precast wall panel mold, the limiting position is adjusted. The threaded pin 5 passes through the pre-set threaded holes on the top of the fixed seat 3 and the docking seat 4, and is fixed by tightening the threads. At this time, the first cleaning nozzle frame 1 and the second cleaning nozzle frame 2 are stably connected into a whole, forming a reliable cleaning frame. When cleaning large precast wall panel molds, the two nozzle frames are unfolded and fixed by the limiting threaded pin 5, which can ensure the stability of the device structure during the cleaning process and prevent shaking or misalignment, thereby ensuring comprehensive and effective cleaning of the inner wall of the mold. The sides of the first cleaning nozzle frame 1 and the second cleaning nozzle frame 2 are symmetrically welded with U-shaped frames 7. The two U-shaped frames 7 are used to clamp the crossbar 8. After the crossbar 8 is placed into the groove of the U-shaped frame 7, the positioning threaded rod 9 is used to pass through the corresponding threaded holes on the U-shaped frame 7 and the crossbar 8 for thread tightening and fixing. The crossbar 8 plays a role in enhancing the structural strength of the entire device, making the cleaning device more stable and less prone to deformation when subjected to the reaction force generated during the cleaning process. During the cleaning process, the reaction force generated by the high-pressure water impacting the inner wall of the mold is large. The crossbar 8 can effectively disperse these forces, ensure the stability of the device, and ensure the smooth progress of the cleaning work.

[0021] A first connector 10 is located at the midpoint of the positioning threaded rod 9. The surface of the first connector 10 is threaded. One end of the fixing rod 11 is connected to the first connector 10 via a thread. The operator can adjust the relative position of the fixing rod 11 with the positioning threaded rod 9 by rotating it according to the actual mold size, thereby changing the local structural extension range of the cleaning device. The other end of the fixing rod 11 is also threaded. The adjusting rod 12 is connected to the fixing rod 11 via a thread. When dealing with molds of different sizes, the operator holds the adjusting rod 12 and rotates it to change the connection length between the adjusting rod 12 and the fixing rod 11, thereby adjusting the local length or angle of the cleaning device to better adapt to the shape and size of the mold's inner wall. For example, for smaller molds, the connection length between the adjusting rod 12 and the fixing rod 11 can be appropriately shortened, allowing the cleaning device to act more accurately on the inner wall of the mold; for larger molds or molds with special structures, the connection length can be extended or the angle adjusted to achieve comprehensive cleaning of all parts of the inner wall of the mold.

[0022] The limiting threaded pin 5 passes through one end of the docking seat 4 and is further connected to the limiting sleeve 6 by threads. The inner diameter of the limiting sleeve 6 matches the outer diameter of the limiting threaded pin 5, and its inner wall is provided with threads that are compatible with the threads on the surface of the limiting threaded pin 5. After the limiting threaded pin 5 passes through the fixing seat 3 and the docking seat 4 and is initially fixed, the limiting sleeve 6 is rotated and screwed onto the end of the limiting threaded pin 5 that passes through the docking seat 4. The main function of the limiting sleeve 6 is to prevent the limiting threaded pin 5 from falling off due to vibration, external force, or other factors during use. During the operation of the cleaning device, the device will vibrate to a certain extent due to the impact of high-pressure water and the reaction force of the inner wall of the mold on the cleaning components. Without the limiting sleeve 6, the limiting threaded pin 5 may gradually loosen or even fall off under the vibration, causing the connection between the first cleaning nozzle frame 1 and the second cleaning nozzle frame 2 to fail, affecting the normal progress of the cleaning work.

[0023] The end of the adjusting rod 12 furthest from the fixed rod 11 is fixedly connected to a handle 13 by welding or other fixed connection methods. The handle 13 is ergonomically designed, usually cylindrical or with a certain curvature, and its surface is provided with anti-slip texture to increase the friction between the operator's hand and the handle 13 and prevent slippage during operation.

[0024] In actual operation, when it is necessary to adjust the local length or angle of the cleaning device, the operator only needs to hold the handle 13 and rotate the handle 13 to drive the adjusting rod 12 to rotate. Since the adjusting rod 12 is connected to the fixed rod 11 by a thread, rotating the adjusting rod 12 can adjust the length of the adjusting rod 12 within the fixed rod 11, which is convenient to use. In addition, the existence of the handle 13 provides the operator with a convenient way of operation, enabling the operator to control the rotation of the adjusting rod 12 more easily and accurately, improving the ease of operation and flexibility of the cleaning device. For example, during the cleaning process, when it is necessary to quickly adjust the cleaning device to adapt to local changes in the inner wall of the mold, the operator can quickly hold the handle 13 to operate without the need for other tools, which greatly shortens the adjustment time and helps the operator to quickly and efficiently complete the cleaning work of the inner wall of the mold, thus improving the overall work efficiency.

[0025] The surface of the fixing rod 11 is fixedly connected to a limiting component 17 by welding or other methods. The limiting component 17 is a metal component with a certain strength. One end of the water pipe connector 16 is provided with an external thread that matches the threaded hole on the limiting component 17. During installation, the threaded end of the water pipe connector 16 is threadedly connected to the threaded hole on the limiting component 17. The main function of the limiting component 17 is to fix and limit the water pipe connector 16. During the operation of the cleaning device, due to the flow of high-pressure water and the vibration of the device, the water pipe connector 16 may be subjected to large tensile forces and torques. Without the fixation of the limiting component 17, the water pipe connector 16 may loosen, shift, or even fall off, leading to high-pressure water leakage, affecting the normal progress of the cleaning work, and potentially posing safety hazards to the surrounding environment and operators.

[0026] By threading the water pipe connector 16 to the limiting member 17, the water pipe connector 16 is firmly fixed to the fixing rod 11, avoiding loosening and falling off due to external forces. This ensures that high-pressure water can flow steadily and smoothly into the injection valve 15 through the water pipe connector 16, guaranteeing the normal operation and cleaning effect of the cleaning device. Under the impact of high-pressure water, the water pipe connector 16 will be subjected to a large tensile force, but due to the fixing effect of the limiting member 17, the water pipe connector 16 always maintains a stable connection and there will be no leakage problem, ensuring the continuity and effectiveness of the cleaning work.

[0027] The injection valve 15 is installed in the middle of the first cleaning nozzle frame 1, and the U-shaped frame 7 maintains a certain distance from the injection valve 15 so that they do not contact each other. Positioning the injection valve 15 in the middle of the first cleaning nozzle frame 1 facilitates the uniform distribution of high-pressure water inside the first cleaning nozzle frame 1. When high-pressure water flows into the injection valve 15 through the water pipe connector 16, because the injection valve 15 is located in the middle, the water can flow more smoothly in all directions of the nozzle frame, ensuring that each nozzle on the nozzle frame receives relatively uniform water pressure and flow rate. This guarantees a comprehensive and uniform rinsing of the inner wall of the mold, improving the cleaning effect. The design that the U-shaped frame 7 does not contact the injection valve 15 is to avoid interference between them. During the operation of the cleaning device, the U-shaped frame 7 needs to withstand horizontal... The weight of components such as rod 8 and positioning threaded rod 9, as well as the reaction force generated during the cleaning process, will cause a certain degree of slight deformation or vibration. If the U-shaped bracket 7 comes into contact with the injection valve 15, it may cause friction and collision between the two, which may not only damage the injection valve 15 and the U-shaped bracket 7, but also affect the normal operation of the injection valve 15, leading to problems such as high-pressure water leakage or unstable flow. By keeping the two from contacting each other, this interference phenomenon is effectively avoided, ensuring the normal operation of each component of the cleaning device and the smooth progress of the cleaning work. For example, during long-term use, due to the avoidance of interference, the injection valve 15 can always maintain a normal working state, and there will be no problems such as poor sealing or valve damage caused by collision, thus ensuring the reliability and stability of the cleaning device.

[0028] The U-shaped frame 7 has a second connector 14 in the middle. The surface of the second connector 14 is threaded. One end of the fixing rod 11 is connected to the first connector 10 by the thread, and the other end can be connected to the second connector 14 by the thread according to actual needs. When the first cleaning nozzle frame 1 and the second cleaning nozzle frame 2 are flipped and folded together, they can be fixed and used, which is convenient for cleaning molds with small space.

[0029] 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.
