TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, and particularly relates to a steel plate wall construction auxiliary equipment. BACKGROUND

[0002] In the steel plate wall rust removal scene, the angle grinder is the core equipment to complete the rust removal operation in the prior art, and the basic operation process is that the worker holds the handle of the angle grinder, sticks the rotating grinding disc of the device to the surface of the steel plate wall, removes the rust on the surface of the steel plate wall through the friction between the grinding disc and the steel plate wall, and finally realizes the rust removal target. However, in the rust removal process, a large amount of dust containing metal debris and rust powder is generated through the friction between the grinding disc and the steel plate wall, and the dust is easy to spread in the working environment. If the worker lacks protective measures, the spread dust will be inhaled into the respiratory tract, and long-term accumulation may damage the lung health. At the same time, the motor of the angle grinder is easy to heat for a long time, the existing heat dissipation hole design is unreasonable, the heat dissipation is poor, the motor performance is affected, and there is a safety hazard. At the same time, since the installation mode of the handle of the angle grinder is fixed, the worker needs to hold the device when working, the worker is easy to be tired, and there is a risk of device falling.

[0003] Further, after the rust removal is completed, the filter screen of the angle grinder needs to be disassembled with the aid of tools, which is time-consuming and laborious, is not suitable for high-frequency cleaning, and is easy to cause dust pollution during disassembly and cleaning. At the same time, the dust on the inner wall of the protective cover is closely attached due to static electricity and moisture, and the worker is not convenient to clean, and the cleaning operation is difficult to be completed efficiently. SUMMARY

[0004] In order to overcome the shortcomings that the dust spreads everywhere during rust removal, the motor cannot be effectively cooled, the worker is slippery when holding in high-temperature weather, and the dust adhered to the protective cover cannot be effectively cleaned, the present application provides a steel plate wall construction auxiliary equipment.

[0008] Furthermore, a ring of heat dissipation holes is provided in the middle of the connecting shell, which can blow the internal gas out to the surroundings to cool down the area around the personnel.

[0009] Furthermore, several magnets are fixed to the circumference of the filter screen.

[0010] Furthermore, a pair of protrusions are symmetrically installed on the connecting shaft.

[0011] Furthermore, it also includes a movable ring, a fixed ring, an air supply pipe, elastic elements, and a plug; the movable ring is installed on the drive component; a fixed ring is provided on the square shell; an air supply pipe is installed at the lower part of the square shell, and the air supply pipe is connected to the filter cone; several elastic elements are arranged circumferentially inside the air supply pipe; a plug is provided inside the air supply pipe to restrict the airflow to pass in one direction, and each elastic element is fixedly connected to the plug.

Detailed Implementation

[0019] The preferred technical solution of the present invention will be described in detail below with reference to the accompanying drawings. Example

[0020] A type of auxiliary equipment for steel plate wall construction, such as Figures 1-4 As shown, it includes a dust cover 1, a trapezoidal shell 2, and a square shell 3; the square shell 3 is mounted on the trapezoidal shell 2; the dust cover 1 is mounted on the trapezoidal shell 2; a connecting shell 4 is fixedly connected to the square shell 3; a handle 5 is rotatably connected to the connecting shell 4; an installation shaft 7 is installed inside the trapezoidal shell 2; a fixing shaft 8 is installed inside the trapezoidal shell 2; a bevel gear set 6 is provided on the installation shaft 7, and the fixing shaft 8 is connected to the bevel gear set 6; a fixing shaft 8 is installed on the side of the bevel gear set 6; a heat dissipation hole 4001 is annularly opened in the middle of the connecting shell 4, which can blow the internal gas to the surroundings to cool the area around the personnel; several heat dissipation vents 5001 are opened at the lower part of the handle 5; It also includes a filter screen 101, a filter cone 102, a sponge 103, a water inlet pipe 104, a drive component 105, a connecting shaft 106, a fan 107, a rack 108, and a spur gear 109; a filter screen 101 is provided at the lower part of the dust cover 1; a filter cone 102 is installed on the dust cover 1; the filter cone 102 has several suction holes 10201 circumferentially opened; the filter cone 102 has several blowing holes 10202 circumferentially opened; a sponge 103 is installed inside the filter cone 102; the filter cone 105... 2 is equipped with a water inlet pipe 104; a drive component 105 is installed inside the connecting housing 4; the drive component 105 is a motor; a connecting shaft 106 is installed on the output end of the drive component 105; a fan 107 is installed on the connecting shaft 106; a rack 108 is slidably connected inside the connecting housing 4, and the rack 108 is fixed to the drive component 105; a spur gear 109 is installed on the rack 108; several ball bearings 1001 are arranged in a ring on the dust cover 1, which can move around in conjunction with the corneal machine when removing rust from the steel plate wall.

[0021] The connecting shell 4 has an annular groove on its right side; the handle 5 can cooperate with the annular groove on the connecting shell 4 to achieve the rotation of the handle 5.

[0022] The filter screen 101 is circumferentially fixed with several magnets; it is installed on the dust cover 1 by magnetic attraction, so that it can be removed when cleaning is required.

[0023] A pair of protrusions are symmetrically installed on the connecting shaft 106; the protrusions can cooperate with the slots opened on the fixed shaft 8, thereby driving the bevel gear set 6 to rotate.

[0024] In steel plate wall rust removal operations, existing technologies primarily utilize angle grinders. Workers hold the handle 5 of the angle grinder, bringing the rotating grinding disc into contact with the steel plate wall surface. The friction between the grinding disc and the steel plate wall removes surface rust. However, this process generates a large amount of dust, which easily spreads in the work environment. If workers do not take adequate protective measures, this dust can be inhaled, potentially damaging lung health over time. Existing filters are insufficient to effectively filter the absorbed dust, allowing some to circulate or escape with the airflow. Furthermore, the motor continuously operates during prolonged rust removal operations. The existing technology has poorly designed heat dissipation holes 4001 for the motor, resulting in low heat dissipation efficiency and an inability to dissipate the heat generated by the motor in a timely manner. Long-term operation at high temperatures may not only reduce motor performance and shorten its service life, but may also cause safety hazards due to overheating. When workers are removing rust, the installation method of the existing angle grinder handle 5 restricts the workers to adopt a "supporting angle grinder" posture. This posture requires the workers to continuously bear the weight of the equipment, which can easily lead to hand and arm muscle fatigue after a long period of operation, increasing the workload of the workers. At the same time, the unstable grip posture may also affect the rust removal accuracy and even pose a safety risk of the equipment slipping.

[0025] To address the aforementioned issues, when rust removal is required on the steel plate wall, the drive unit 105 is activated. This drives two meshing bevel gear sets 6 to rotate via the connecting shaft 106, thereby rotating the grinding disc mounted on the lower part of the mounting shaft 7 to remove rust from the steel plate wall. At this time, the fan 107 rotates forward, generating suction around the grinding disc, drawing the dust generated during rust removal onto the filter screen 101. Since the filter screen 101 cannot completely filter the dust, some dust remains in the intake air. Water is then introduced into the filter cone 102 through the water inlet pipe 104. The sponge 103 installed in the filter cone 102 absorbs the water. The dust-laden air then passes through the suction... The gas enters through hole 10201 into filter cone 102. After being absorbed by the moist sponge 103, the gas mixed with dust is purified. The purified gas then enters the connecting shell 4, carrying the heat generated by the drive component 105, and exits the angle grinder through heat dissipation holes 4001 and vents 5001. As the gas exits through these holes, it cools and dries the worker's face and hands holding the handle 5, preventing slippage and the angle grinder from falling. However, when rust removal is required at the bottom of a steel wall, the worker needs to support the angle grinder, which can place a significant burden on them over time. Figure 2As shown, handle 5 is attached to connecting shell 4. When rust removal is required on the bottom of the steel plate wall, the angle grinder is inverted to support the angle grinder. The inverted grinding disc contacts the bottom of the steel plate wall to remove rust. At this time, the worker can rotate handle 5 to change from supporting the angle grinder to lifting it. This can save effort and improve safety, preventing the angle grinder from falling due to the worker's exhaustion when supporting it, thus preventing injury. Example

[0026] Based on Example 1, such as Figures 5-7 As shown, it also includes a movable ring 201, a fixed ring 202, an air supply pipe 203, an elastic element 204, and a plug 205; the movable ring 201 is installed on the drive component 105; the fixed ring 202 is provided on the square shell 3; the air supply pipe 203 is installed at the lower part of the square shell 3, and the air supply pipe 203 is connected to the filter cone 102; a number of elastic elements 204 are arranged circumferentially inside the air supply pipe 203; the elastic element 204 is a spring; a plug 205 is provided inside the air supply pipe 203, and each elastic element 204 is fixedly connected to the plug 205.

[0027] The fixed ring 202 has a through hole; it can cooperate with the movable ring 201 so that the air intake channel can be closed when the fan 107 reverses to blow air.

[0028] The gas pipe 203 is a special-shaped pipe with a check valve function; the gas pipe 203 allows the airflow to pass through in a unidirectional manner from top to bottom.

[0029] The plug 205 is conical; the plug 205, together with the gas pipe 203 and the elastic element 204, can form a simple one-way valve function.

[0030] Furthermore, after rust removal, workers need to manually remove the filter screen 101 on the angle grinder. This process requires tools and is time-consuming and laborious, making it unsuitable for the need for rapid cleaning after high-frequency operations. Due to the inconvenience of disassembly and the lack of a convenient cleaning design, dust is easily scattered during the disassembly and cleaning of the filter screen 101, which can contaminate the working environment or other parts of the equipment. At the same time, dust will adhere tightly to the inner wall of the protective cover due to electrostatic adsorption, moisture adhesion, and other reasons, making it inconvenient for workers to clean and unable to complete the cleaning work efficiently.

[0031] To address the aforementioned issues, after rust removal, since the filter screen 101 is magnetically attached to the dust cover 1, it can be directly removed for cleaning. Then, the operator moves the spur gear 109 to the left, causing the rack 108 to move to the right, which in turn moves the drive component 105, connecting shaft 106, and fan 107 to the right. This also moves the movable ring 201 to the right. When the connecting shaft 106 disengages from the slot in the fixed shaft 8, the movable ring 201 engages with the through hole in the fixed ring 202, sealing the passage for gas from the trapezoidal shell 2 into the square shell 3. This prevents gas from entering the trapezoidal shell 2 and causing wear on the bevel gear set 6. At this point, the drive is then activated. Part 105 is reversed, causing the fan 107 to reverse as well. At this time, the fan 107 will absorb external gas through the heat dissipation hole 4001 and the heat dissipation port 5001. The gas will then enter the air supply pipe 203. As the gas enters the air supply pipe 203, the plug 205 will move down, thereby compressing the elastic element 204. The gas will then enter the internal cavity of the filter cone 102. Part of the gas will be ejected through the air blowing hole 10202, blowing off the dust remaining on the inner wall of the dust cover 1, thus cleaning the dust cover 1. The other part of the gas will enter the sponge 103 and then be blown out through the air suction hole 10201, which can blow off the dust adhering to the sponge 103, improving the cleaning efficiency and thus adapting to high-frequency rust removal work.
