Description

Technical Field

[0001] The utility model relates to the technical field of rubber-lined storage tanks, in particular to a device for quickly repairing rubber-lined storage tanks. Background Art

[0002] Rubber lining, also known as rubber lining, is a pre-processed rubber sheet bonded to a metal surface using adhesive to isolate corrosive media from the metal substrate for protection. Rubber-lined storage tanks are leak-proof, non-toxic, age-resistant, impact-resistant, corrosion-resistant, and have a long service life, making them ideal for storing and transporting corrosive liquids. However, after prolonged use, rubber-lined tanks can experience problems such as peeling and rusting on the outer surface of the lining, which are often repaired manually.

[0003] According to the announcement number CN220279110 U, the patent uses a servo motor to make a bidirectional screw drive the grinding strips on both sides to move toward each other, thereby clamping the side of the tank body, and driving the grinding strips to rotate by the drive motor to achieve grinding and repairing the inner wall of the rubber-lined storage tank. However, the above patent uses several clamping hydraulic cylinders to clamp and fix the outer side of the tank body. This cannot ensure that the center of the tank body and the center of the grinding strip are on the same vertical line, resulting in inconsistent thickness of the grinding strip when rotating and grinding, and it is impossible to grind the inner walls of tanks of different sizes. Utility Model Content

[0006] Preferably, the output end of motor 1 extends to the top of the base and is fixedly connected to the rotating plate. The limiting grooves are evenly distributed in a circular array around the center of the rotating plate. The limiting grooves are arc-shaped grooves and are slidably connected to the outer side of the slide rod.

[0007] Preferably, the slide groove is a straight groove, the slide groove is slidably connected to the outer side of the slide rod, one end of the slide groove extends above the rotating plate and is fixedly connected to the clamping plate, and the clamping plate is an arc-shaped plate.

[0008] Preferably, the output end of the second motor extends to the bottom of the lifting plate and is fixedly connected to the connecting plate. A rectangular groove is provided on the side of the support frame, and the support frame is slidably connected to the outer side of the lifting plate through the rectangular groove.

[0009] Preferably, the interior of the guide groove is slidably connected to the top of the grinding strip, and the number of the grinding strips is two, and the grinding strips are symmetrically distributed on both sides of the electric telescopic rod.

[0010] Preferably, the fixed plate is movably hinged to one end of the hinged plate through a hinge groove, and the other end of the hinged plate is hinged to the grinding strip.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model is provided with a rotating shaft, a rotating plate, a limiting groove, a sliding groove, a sliding rod and a clamping plate. The rotating shaft and the rotating plate are rotated by a motor, and the sliding rod is moved inside the sliding groove through the limiting groove until the clamping plate fixes the can body on the surface of the rotating plate. The four symmetrical clamping plates ensure that the center of the can body and the center of rotation of the grinding strip are on the same vertical line, ensuring uniform grinding. The can bodies of different sizes can be clamped and fixed by the movement of the clamping plates.

[0013] The utility model also provides a lifting plate, a connecting plate, a guide groove, a fixed plate, a hinged plate and a grinding strip, and the fixed plate is moved up and down by an electric telescopic rod, so that the hinged plate pushes the grinding strip to move inside the guide groove, thereby realizing the adjustment of the position of the grinding strips on both sides, ensuring that the grinding strips abut against the inner walls of tanks with different inner diameters, so that the overall device can be suitable for grinding and repairing tanks with different inner diameters.
