Description

Technical Field

[0001] The utility model relates to the technical field of rust removal tools, in particular to a rust removal tool for large loading and unloading equipment. Background Art

[0002] There are many large-scale mechanical loading and unloading equipment made of metal distributed on the seaport container terminal. After years of exposure to humid air and seawater, they are easily corroded and rusted. The location and size of the rust are uncontrollable, making it difficult to remove the rust from the large-scale mechanical loading and unloading equipment. In actual operation, operators of seaport container terminals often use standard tools such as hammers to remove rust by knocking, which is time-consuming and laborious, and cannot meet the busy on-site production needs. There are great disadvantages in the rust removal process.

[0003] In addition, although there are many rust removal machines on the market, there are also many disadvantages:

[0004] (1) If the rust removal machine has a high degree of mechanization and can realize computer-controlled automatic rust removal, although it saves time and effort, the purchase cost and maintenance cost will be greatly increased, which will bring certain economic pressure to small and medium-sized enterprises;

[0005] (2) Large-scale mechanical loading and unloading equipment is often bulky. If the rust removal machine is heavy, it will be inconvenient for operators to get on and off the large-scale mechanical loading and unloading equipment, and it cannot meet the busy on-site production needs.

[0006] (3) When removing rust, loose small pieces of stains and rust will float in the air, which can easily be inhaled by operators, affecting their health.

[0007] Therefore, in actual rust removal operations, operators need to have rust removal tools for large loading and unloading equipment that are small and light, easy to carry, low cost, and can absorb and remove stains and rust without secondary treatment and without affecting human health. Utility Model Content

[0008] In view of the problems that rust removal tools for large loading and unloading equipment are either time-consuming and labor-intensive, or costly and difficult to promote universally, the utility model provides a rust removal tool for large loading and unloading equipment, which is small and light, easy to carry, can absorb and remove stains and rust, and saves time and labor.

[0009] The technical solution of this utility model is as follows:

[0010] A rust removal tool for large loading and unloading equipment comprises an operating rod, which is a tube with openings at both ends. A thread is arranged on the inner side of one end of the operating rod, the operating rod is connected to a rust removal plug through a thread, and the other end is detachably connected to one end of a connecting tube, and the other end of the connecting tube is connected to a negative pressure suction device. An air suction hole, a baffle and a handle are arranged in sequence on the outer side wall of the operating rod, wherein the air suction hole is close to the end of the operating rod connected to the rust removal plug.

[0011] Furthermore, the shape of the rust removal plug is selected from an octagonal pyramid shape, a hoe shape or a wedge shape.

[0012] Furthermore, the number of the handles is two.

[0013] Furthermore, a storage box is provided in the negative pressure suction device.

[0014] Furthermore, the baffle is in a trumpet shape and surrounds the outer side wall of the operating rod, with the trumpet mouth facing the rust removal plug.

[0015] Furthermore, the material of the rust removing plug is stainless steel.

[0016] The beneficial effects of the utility model are:

[0017] The utility model provides a rust removal tool for large loading and unloading equipment, which is small, light and easy to carry. The operator holds the handle and uses the rust removal plug to remove rust. The loose rust and stains are sucked by the negative pressure suction device, which not only avoids the operator from inhaling and affecting the health, but also saves the subsequent cleaning process, saving time and labor. The baffle can block the rust and stains that are not completely absorbed during the first absorption, which is convenient for re-absorption. The connecting pipe and the operating rod are detachably connected and assembled on site by the operator when in use, which is convenient for the operator to carry with him before and after use.

[0024] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0025] Example 1

[0026] Reference Figure 1-Figure 4 A rust removal tool for large loading and unloading equipment includes an operating rod 4, which is a tube with openings at both ends. A thread is arranged on the inner side of one end of the operating rod 4. The operating rod 4 is connected to the rust removal plug 1 by threads. The shape of the rust removal plug 1 made of stainless steel is selected from an octagonal pyramid shape, a hoe shape or a wedge shape. The other end of the operating rod 4 is detachably connected to one end of a connecting pipe 3, and the other end of the connecting pipe 3 is connected to a negative pressure suction device 2. A storage box is arranged in the negative pressure suction device 2. An air suction through hole 7, a baffle 6 and two handles 5 are arranged on the outer wall of the operating rod 4 in sequence, wherein the air suction through hole 7 is close to the end where the operating rod 4 is connected to the rust removal plug 1, the number of the air suction through holes 7 is three, and the baffle 6 is in a trumpet shape and surrounds the outer wall of the operating rod 4, with the trumpet mouth facing the rust removal plug 1.

[0027] When in use, the operator carries the large loading and unloading equipment rust removal tool to the place where the large loading and unloading equipment is rusted. According to the specific rust situation, the operator makes a judgment, selects rust removal plugs 1 of different shapes to assemble the large loading and unloading equipment rust removal tool, and holds the handle 5 to perform rust removal. When the rust area is large, the rust removal plug 1 in the shape of a wedge is selected to scrape the rust, or the rust removal plug 1 in the shape of a hoe is selected to shovel or knock out the rust. When the rust area is small, the rust removal plug 1 in the shape of an octagonal pyramid is selected to shovel, knock out or scrape the rust. While removing the rust, the negative pressure suction device 2 is started, and the loose dirt and rust are sequentially passed through the inside of the operating rod 4 and the connecting pipe 3 through the suction through hole 7, and adsorbed into the storage box of the negative pressure suction device 2. The length of the connecting pipe 3 is selected according to the specific situation. If the operation is near the ground, the negative pressure suction device 2 can be placed near the operator for single-person operation. If the operation is far away from the ground, the negative pressure suction device 2 is controlled by the second operator, and the two operators cooperate in the operation through the communication equipment.
