Description

Technical Field

[0001] The utility model relates to a device applied to the field of metal pipeline rust prevention, in particular to a metal surface rust prevention liquid spraying device. Background Art

[0002] Anti-rust liquid has high anti-corrosion performance and strong adhesion. It can be sprayed on the surface of the workpiece to protect iron and non-ferrous metal products and equipment. In order to facilitate the anti-rust treatment of workpieces, people have developed various anti-rust liquid spraying equipment. For example: Chinese patent CN211937479U discloses an environmentally friendly silicon steel anti-rust liquid spraying equipment, Chinese patent CN206716269U discloses a device for spraying anti-rust liquid on oil drums after cleaning, and Chinese patent CN219615837U discloses a metal mesh plate coating anti-rust liquid device, etc. These spraying devices either have no workpiece positioning frame and can only spray simply, or the workpiece positioning frame set can spray the inner wall of the oil drum or the metal mesh plate, which is not suitable for spraying anti-rust liquid on the inner wall of the pipeline, especially the inner wall of the large pipeline.

[0003] In order to solve the above problems, people have been seeking an ideal technical solution. Utility Model Content

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. "Installed", "provided with", "connected", etc. can adopt conventional means in the prior art, such as: integral setting, snap-on installation, welding connection, adhesive connection, bolt connection, etc. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances, and suitable connection, setting or installation methods can be selected in the prior art.

[0020] like Figure 1-2 As shown, a metal surface anti-rust liquid spraying device includes a frame and a liquid storage bin (not shown) installed on the frame, the storage bin is connected to the spraying assembly through a feed pipe 1, specifically, the frame can be a mobile frame with walking wheels in the prior art, or a common bracket, which plays the role of supporting the storage bin, and the rust removal liquid is placed in the storage bin. In addition, a common delivery pump can be used to connect the feeding pipe to provide delivery power, and a valve structure can also be used to adjust the flow rate. The feeding pipe 1 is a flexible pipe section; the spraying assembly includes a hard pipe section 2, the rear end of the hard pipe section 2 is connected to the feeding pipe 1, the front end of the hard pipe section 2 is connected to a rotating nozzle 4, the outer wall of the hard pipe section 2 is provided with a support sleeve, and a plurality of groups of support frames 5 are evenly arranged around the circumference of the support sleeve, and the outer ends of the support frames 5 are respectively provided with walking wheels 3. Specifically, if it is usually used for a shorter metal pipe, the spraying assembly can be pushed and pulled by manpower, and if it is mainly used for a longer pipe, in order to save manpower, a battery box and a micro motor can be installed to drive the walking wheel to walk.

[0021] In one embodiment, the support frame 5 includes several groups of articulated frames, each group of articulated frames includes two articulated connecting rods 7, the middle parts of the two articulated connecting rods 7 are articulated to form an X-shaped frame, and the ends of any two adjacent X-shaped frames are articulated, and at least two of the articulated connecting rods 7 are respectively provided with positioning columns, and the two positioning columns are connected by positioning struts 8, and the positioning struts 8 are provided with two groups of positioning holes, and the positioning columns are inserted into the positioning holes. One or more positioning struts can be provided, and during use, the length of the support frame can be adjusted according to the inner diameter of the metal pipe, so that the running wheels can run close to the inner wall of the metal pipe to ensure the stability of the spraying process.

[0022] In one of the embodiments, a threaded hole or a threaded groove is provided on the positioning column, and the positioning column is inserted into the positioning hole and locked by a locking bolt, thereby improving the stability of the connection structure and facilitating disassembly.

[0023] In one of the embodiments, a travel wheel 3 is installed at the end of the articulated link 7 farthest from the hard pipe section 2. In a group of X-shaped frames close to the hard pipe section 2, one of the articulated links 7 is hinged to the support sleeve, and the other articulated link 7 is slidably matched with the support sleeve, so as to facilitate the length adjustment of the articulated frame.

The two supporting leg ends of the U-shaped structure are hinged to the outer side of the hard pipe section 2, so as to facilitate pushing, pulling or stabilizing the spray assembly when the spray assembly is close to the end.

[0027] In one of the embodiments, a torsion spring is installed on the hinge axis between the lifting handle 6 and the hard pipe section 2. In a natural state (i.e., when not subject to other external forces), the lifting handle 6 is close to the hard pipe section 2 under the action of the torsion spring to prevent the handrail from scratching the inner wall of the pipe.

[0028] During specific use, the spray component enters the interior of the metal pipe. When the front end of the spray component reaches the other end of the metal pipe from one end of the metal pipe, spraying begins. While spraying, the walking wheels move in the opposite direction along the inner wall of the metal pipe (reverse means opposite to the walking direction of the spray component during the entry process) until the walking wheels reach one end of the metal pipe, stabilize the spray component, and allow the spray component to complete spraying and exit the metal pipe.

[0029] The above embodiments can be combined with each other.
