Description

TECHNICAL FIELD

[0001] The present application belongs to the field of engineering machinery, and particularly relates to a sand blasting rust removal device and a high-altitude rust removal equipment using the same. BACKGROUND

[0002] Due to long-term immersion in seawater, the seawater will corrode the surface of the ship, causing the surface of the ship to rust. In the process of ship repair, rust removal is an indispensable link.

[0003] At present, a sand blasting rust removal device is generally used for rust removal. The sand blasting rust removal device mainly comprises a sand blasting gun, a sand blasting nozzle, a sand inlet and a recovery port connected to the inside of the sand blasting gun. During the rust removal operation, the sand blasting gun is moved to the sand blasting nozzle and abuts against the operation surface to form a closed operation space between the inside of the sand blasting gun and the operation surface. The sand blasting gun inputs the sand pellets into the operation space through the sand inlet. The sand pellets continuously impact the operation surface in the operation space, so that the rust and waste paint on the operation surface are peeled off. The peeled rust and waste paint and other waste are flowed into the preset recovery device through the recovery port of the sand blasting gun.

[0004] However, in the existing sand blasting rust removal device, the pressure of the sand blasting gun abutting against the operation surface is unstable. When the pressure of the sand blasting gun abutting against the operation surface is too small, part of the sand pellets and the peeled rust and waste paint will flow out from the gap between the sand blasting nozzle and the operation surface, resulting in poor rust removal effect and waste recovery effect. Or, when the pressure of the sand blasting gun abutting against the operation surface is too large, the friction between the sand blasting nozzle of the sand blasting gun and the operation surface is too large, causing the sand blasting gun to have large resistance when moving and being difficult to move.

[0037] DETAILED DESCRIPTION

[0038] ​​​The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in this invention can be combined with each other.

[0040] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used to describe the relative positions of components in relation to the directions shown in the accompanying drawings or in relation to the vertical, perpendicular, or gravitational directions.

[0041] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0042] The present invention first provides a sandblasting rust removal device.

[0043] In one implementation, refer to the appendix. Figure 2 and attached Figure 3 As shown, the sandblasting and rust removal device includes a sandblasting mechanism 11, a moving mechanism 12, a force sensor 13, and a controller. The sandblasting mechanism 11 includes a connecting bracket 111, a sliding seat 112, an elastic element 113, and a sandblasting gun 114. The sliding seat 112 is slidably disposed on the connecting bracket 111 along a first direction X. The elastic element 113 is configured to extend along the first direction X and connect between the connecting bracket 111 and the sliding seat 112. The sandblasting gun 114 is disposed on the sliding seat 112. The moving mechanism 12 includes a first moving module 121, which is used to drive the connecting bracket 111 to reciprocate along the first direction X. The force sensor 13 is used to detect the pressure on the elastic element 113. The controller is communicatively connected to the force sensor 13 and is used to control the first moving module 121 to drive the connecting bracket 111 to move according to the pressure detected by the force sensor 13, so that the pressure on the elastic element 113 is maintained within a preset pressure range.

[0044] It can be understood that in the sand blasting rust removal device of the embodiment, the elastic member 113 is connected between the connecting bracket 111 and the sliding seat 112, and the sand blasting gun 114 is arranged on the sliding seat. When the sand blasting gun 114 abuts against the working surface to perform the rust removal work, the elastic member 113 can continuously apply the elastic force to the sliding seat 112, so that the sand blasting gun 114 can be tightly attached to the working surface. The reaction force of the working surface to the sand blasting gun 114 is transmitted to the elastic member 113 through the sliding seat 112. The pressure of the elastic member 113 is detected by the force sensor 13 to indirectly obtain the pressure of the sand blasting gun 114 abutting against the working surface. The first moving module 121 is controlled to drive the connecting bracket 111 to move according to the detection information fed back by the force sensor 13, so that the pressure of the elastic member 113 is kept within the preset pressure range, and the pressure of the sand blasting gun 114 abutting against the working surface is kept within the preset pressure range. In this way, the pressure of the sand blasting gun 114 abutting against the working surface can be stabilized within a suitable range during the operation of the sand blasting rust removal device, so that the closed operation space formed between the inside of the sand blasting gun 114 and the working surface is relatively stable. The problems that part of the sand pellets and the peeled rust and waste paint flow out from the gap between the sand blasting opening and the working surface or the friction force between the sand blasting opening of the sand blasting gun 114 and the working surface is too large, causing the sand blasting gun 114 to have a large resistance when moving and being difficult to move, are effectively avoided.
