Description

Technical Field

[0001] This utility model relates to the technical field of spray painting equipment, specifically a surface spray painting device for steel structure processing. Background Technology

[0002] In the steel structure manufacturing industry, post-manufacturing surface painting and anti-corrosion treatment are critical processes. Because steel structures are typically large, workers generally use a handheld spraying method where an air pump supplies air to the spray gun via an air hose. During operation, one hand holds the spray gun, while the other hand pulls the air hose to move with the body, ensuring the hose adjusts synchronously with changes in the spraying position.

[0003] This traditional operating mode relies on the coordinated use of both hands: the hand holding the spray gun is responsible for precisely controlling the spraying direction and range, while the hand holding the hose must continuously bear the weight of the hose and keep it extended to prevent the hose from becoming tangled or dragging and hindering movement. However, due to the size of the steel structure and the spraying process, each operation takes a long time, and the hand holding the hose must maintain a gripping and pulling posture for an extended period of time.

[0004] In practical applications, prolonged use of the air hose can cause hand muscles to become fatigued and sore due to prolonged stress, and may even lead to decreased operational stability, affecting the uniformity of spraying and the quality of corrosion protection.

[0005] Therefore, there is an urgent need for a technical solution that can reduce the burden of handheld hoses and optimize the ease of operation in order to improve the efficiency of steel structure spraying operations. Utility Model Content

[0009] To achieve the above objectives, this utility model provides the following technical solution: a surface painting device for steel structure processing, including an air hose, a spray gun at one end of the air hose, an air pump at the other end, a fixing plate, a second clamping block at the front side of the fixing plate, a first clamping block hinged to the end of the second clamping block, and a bolt threaded to the first clamping block and threaded to the second clamping block, so that the first clamping block and the second clamping block clamp the air hose, and waist-mounted fixing straps on both sides of the fixing plate.

[0010] Furthermore, one fixing strap is provided with a hook and loop side, and the other fixing strap is provided with a loop side.

[0011] Furthermore, the front side of the first clamping block has an inner groove for receiving the end of the bolt.

[0012] Furthermore, the back of the second clamping block is provided with a T-shaped limiting shaft, which extends into the fixing plate and the two are rotatably connected.

[0013] Furthermore, a rubber contact plate is provided on the back of the fixing plate.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides a surface painting device for steel structure processing, which has the following beneficial effects:

[0016] This surface painting device for steel structure processing uses first and second clamping blocks to hold an air hose and fix them together with bolts. The air hose is then fixed to the operator's waist by two fastening straps that can fit together, making it easy for the operator to hold the spray gun to paint the steel structure. When the operator changes position, the air hose moves with the operator, eliminating the need for the operator to hold the air hose and reducing the burden on the operator's hands.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-2 The steel structure processing surface painting device of this utility model includes an air pump, an air hose 1 and a spray gun. The air pump and the spray gun are respectively installed at both ends of the air hose 1. The air pump supplies air to the spray gun along the air hose 1 to atomize and spray the paint in the spray gun. The above is the prior art, and will not be described in detail in this application.

[0022] The air hose 1 is provided with a first clamping block 2 and a second clamping block 3 on both sides. The first clamping block 2 and the second clamping block 3 are fitted with hinges at the same end. The side wall near the first clamping block 2 has a threaded hole, and the side wall near the second clamping block 3 has a threaded groove. When the first clamping block 2 and the second clamping block 3 clamp the air hose 1, the threaded hole and the threaded groove are coaxial in the axial direction. A bolt 4 is installed on the threaded hole, and the end of the bolt 4 enters the threaded groove, so that the first clamping block 2 and the second clamping block 3 clamp and fix the air hose 1.

[0023] The first clamping block 2 has an inner groove 5 on its outer side. The inner groove 5 is placed at the end of the threaded hole. When the bolt 4 fixes the first clamping block 2 and the second clamping block 3, the end of the bolt 4 is retracted into the inner groove 5 to prevent clothing or other external objects from scratching the bolt 4.

[0024] The second clamping block 3 has a fixing plate 6 and a limiting shaft 7 on its back. The limiting shaft 7 is fixedly connected to the second clamping block 3. The front side of the fixing plate 6 has a limiting groove with a T-shaped cross-section, and the limiting shaft 7 is placed in the limiting groove, so that the two match. This allows the air hose 1 held by the first clamping block 2 and the second clamping block 3 to rotate on the fixing plate 6 with the limiting shaft 7 as the axis.

[0025] Both sides of the fixing plate 6 are connected to fixing straps 8. The two fixing straps 8 are respectively provided with hook and loop fasteners and hook and loop fasteners, which are used to fix the air hose 1 to the patient's waist.

[0026] Because the air hose 1 is clamped by the first clamping block 2 and the second clamping block 3, when the spray gun is used to spray paint the steel structure, the air hose 1 can rotate on the fixed plate 6 with the limiting shaft 7, making the operation of the spray gun smoother.

[0027] To prevent the fixation plate 6 from injuring the operator's skin after prolonged contact with the patient's waist, a contact plate 9 is provided on the back of the fixation plate 6. The contact plate 9 is made of rubber and is arc-shaped to fit the operator's waist, thereby improving the comfort of fixing the paint spraying device on the waist.

[0028] When in use, place the air hose 1 between the first clamp 2 and the second clamp 3, then pinch the first clamp 2 and the second clamp 3 together so that the threaded hole of the first clamp 2 corresponds to the threaded groove of the second clamp 3. Then rotate the bolt 4 so that one end of the bolt 4 enters the threaded groove and the other end is placed in the inner groove 5.

[0029] Then, attach the contact plate 9 to the operator's waist, and wrap the two fixing straps 8 around the waist and attach them together to secure the air hose 1.

[0030] The operator holds a spray gun, starts the air pump, and sprays paint on the steel structure. As the operator changes positions, their body moves the air hose 1, thus eliminating the need to hold the air hose 1 for a long time and reducing hand fatigue.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
