Description
Technical Field
[0001] The utility model belongs to the technical field of gate hoist production and relates to a gate hoist shell painting device. Background Art
[0002] The gate hoist is a machine used in various large-scale water supply and drainage, water conservancy and hydropower projects to control the lifting and lowering of various large and medium-sized cast iron gates and steel gates to open and close. It includes screw-type gate hoists, which have a very simple structure and are relatively easy to install. They are widely used in the opening and closing of gates on channel culverts and water diversion hubs.
[0003] Since the working environment of the gate hoist is humid, it is prone to corrosion and rust, which will reduce its service life or even damage the equipment. Therefore, it is necessary to spray paint on the gate hoist shell. This can form a protective film on the gate hoist shell to effectively prevent corrosion and rust and extend the service life of the gate hoist. The gate hoist shell has an irregular shape and requires manual spraying by the operator. During the spraying process, the unattached paint will float in the air, polluting the surrounding air and even affecting the health of the operator.
[0004] Based on this, we designed a gate hoist casing painting device. Utility Model Content
[0005] The purpose of the utility model is to solve the above-mentioned problems in the existing technology and to propose a hoist shell painting device. The technical problem to be solved by the device is: how to collect paint floating in the air when the hoist shell is sprayed with paint to reduce the pollution of the paint to the surrounding air.
[0006] The purpose of the utility model can be achieved through the following technical solutions:
[0007] A gate opening and closing machine shell painting device comprises a U-shaped plate and a movable base, side plates are fixed on both sides of the U-shaped plate, a water collecting trough is arranged at the bottom of the U-shaped plate, a water inlet pipe is fixed on the top of the U-shaped plate, and a plurality of water outlets distributed at equal intervals are opened on the side wall of the water inlet pipe, the side end of the water collecting trough is connected with the water outlet pipe, a rotating rod is rotatably arranged in the middle position of the U-shaped plate, a suction fan is fixed at the front end of the rotating rod, and a driving motor for driving the rotating rod to rotate is fixed to the back side of the U-shaped plate.
[0008] The mobile base comprises a mobile plate, a plurality of universal wheels are installed below the mobile plate, a circular hole is opened in the middle of the mobile plate, a rotating column is rotatably arranged in the circular hole, and a rotating plate is fixed on the upper end of the rotating column.
[0009] With the above structure, when in use, the gate hoist casing that needs to be painted is placed on the rotating plate, and then the movable plate is moved to the middle of the two side plates through the universal wheel. The operator can use the spray gun to spray paint. When the direction needs to be adjusted during the painting process, the rotating plate can be rotated to drive the gate hoist casing to rotate. There is no need to touch the gate hoist casing, and no damage will be caused to the undried paint.
[0010] A magnetic strip is embedded on the outer side wall of the water collecting tank, and the moving plate is made of iron material.
[0011] With the above structure, when in use, the mobile base with the gate opening and closing machine housing can be placed close to the sump, at which time the magnetic strip will absorb the mobile plate to prevent the mobile plate from shaking, making it convenient for the operator to spray paint.
[0012] A plurality of inclined plates are fixed on the inner side of the U-shaped plate, and a plurality of notches distributed at equal intervals are formed on the inclined plates.
[0013] With the above structure, when in use, the water sprayed from the water outlet will flow downward along the inner wall of the U-shaped plate, and will diffuse outward when passing through the inclined plate. Moreover, under the action of the notch, the water flow diffusion effect is further enhanced, and the contact area with the air is increased, which can further improve the adsorption effect on the paint and improve the effect of purifying the air.
[0014] A baffle is fixed in front of the upper end of the U-shaped plate.
[0015] With the above structure, when in use, the baffle can prevent the airflow generated by the suction fan from flowing back to the front and causing airflow turbulence, thereby ensuring that the paint floating in the air can fully follow the airflow into the rear of the suction fan and be absorbed in the water.
[0016] A square rod is fixed at the front end of the rotating rod, and a spring washer is sleeved on the square rod. A square block is rotatably arranged at the front end of the square rod. A square hole is opened in the middle of the suction fan, and a limiting groove is opened at the front end of the suction fan.
[0017] With the above structure, when in use, the square rod is inserted into the square hole, and the block is aligned with the limit groove. Under the elastic force of the spring gasket, the block is located in the limit groove. At this time, the block will not rotate, and the suction fan can rotate synchronously with the rotating rod. When a lot of paint adheres to the suction fan, the operator can push the suction fan backward and compress the spring gasket, rotate the block to align it with the square rod, and then remove the suction fan, clean the paint on its surface, and then reinstall it for use. The installation and disassembly process is simple, which is convenient for the operator to clean the suction fan.
[0018] Compared with the existing technology, the hoist shell painting device has the following advantages:
[0019] 1. Through the U-shaped plate, water inlet pipe and suction fan, when the hoist shell is sprayed with paint, the paint floating in the air will fully contact with water and be absorbed by water, thereby reducing the paint content in the air and reducing the pollution of paint to the surrounding air.
[0020] 2. Water flowing downward along the inner wall of the U-shaped plate through the inclined plate will diffuse outward when passing through the inclined plate, and under the action of the notch, the water flow diffusion effect is further enhanced, and the contact area with the air is increased, which can further improve the adsorption effect on the paint.
[0021] 3. The suction fan can be disassembled and reinstalled through square rods, square blocks and spring washers, and the installation and disassembly process is simple, which is convenient for operators to clean the suction fan. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The working principle of this utility model:
[0040] Before use, water needs to be injected through the water inlet pipe 5, so that the water is sprayed onto the inner wall of the U-shaped plate 1 through the water outlet 6 and flows down along the inner wall of the U-shaped plate 1. When passing through the inclined plate 12, it will diffuse outward, and under the action of the notch 13, the water flow diffusion effect is further enhanced, and the contact area with the air is increased, which can further improve the adsorption effect of the paint. Then turn on the drive motor 10 to drive the suction fan 9 to rotate to generate an airflow to the inside of the U-shaped plate 1. After the airflow is fully in contact with the water flow, it is discharged from the top of the U-shaped plate 1, and under the action of the baffle 14, the airflow will not flow forward. The operator can place the housing of the gate opening machine that needs to be painted on the rotating plate 404, and then move the movable plate 401 to the middle of the two side plates 2 through the universal wheel 402, so that the magnetic strip 11 will adsorb the movable plate 401 to prevent the movable plate 401 from shaking. Then the operator can use the spray gun to spray paint. When the direction needs to be adjusted during the painting process, the rotating plate 404 can be rotated to drive the gate opening and closing machine housing to rotate. There is no need to touch the gate opening and closing machine housing, and no damage will be caused to the undried paint. When spraying paint, the paint floating in the air will follow the airflow into the U-shaped plate 1. In the contact with the water flow, the paint will be absorbed by the water, thereby achieving the effect of purifying the air. The water mixed with the paint will be discharged through the outlet pipe 7, which is convenient for centralized collection and treatment. In addition, when a lot of paint adheres to the suction fan 9, the operator can push the suction fan 9 backward and compress the spring gasket 803, rotate the block 802 to align it with the square rod 801, and then remove the suction fan 9, clean the paint on its surface, and then reinstall it for use. The installation and disassembly process is simple, which is convenient for the operator to clean the suction fan 9.
[0041] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
