[0034] To make the objectives, technical solutions, and beneficial effects of this application clearer, the preferred embodiments of this application will be described in detail below with reference to the accompanying drawings, so as to facilitate understanding by those skilled in the art.

[0035] Example 1:

[0036] See Figure 1 A clamp for a spray gun pipe, comprising a spray gun pipe 1, wherein the clamp for the spray gun pipe further comprises:

[0037] The first semi-circular hoop 2 is fitted onto the burnt side of the spray gun pipe 1;

[0038] The second semi-circular hoop 3 is fitted onto the other side of the burnt position of the spray gun pipe 1;

[0039] Welding joint 4 is formed on the first semi-circular hoop 2 and the second semi-circular hoop 3;

[0040] Among them, the first semi-circular hoop 2 and the second semi-circular hoop 3 are centrally symmetrical about the axis of the spray gun tube 1, and the burn-off notch at the burn-off position corresponds to the weld joint 4.

[0041] Specifically, the first semi-circular arc hoop 2 and the second semi-circular arc hoop 3 together form the main body of the clamp. The two are centrally symmetrically distributed about the axis of the spray gun tube 1 at the burn position of the spray gun tube 1. The clamping force on both sides of the burn position forms a symmetrical bending moment balance, so that the radial pressure of the hoop on the burn area is evenly distributed in 360°, which can avoid local stress concentration and maintain the roundness of the tube. The symmetrically distributed hoop and the spray gun tube 1 form a rigid constraint, which can effectively suppress the displacement deviation caused by thermal deformation or mechanical vibration, realize the rapid calibration of the spray gun, and reduce the maintenance and adjustment time.

[0042] The welding ports 4 opened on the first semi-circular hoop 2 and the second semi-circular hoop 3 correspond to the burn-out notches at the burn-out locations, thus facilitating the welding of the burn-out notches through the welding ports 4, thereby enabling the repair of the burn-out spray gun tube 1.

[0043] By fitting the first semi-circular hoop 2 and the second semi-circular hoop 3 onto the burnt location of the spray gun pipe 1, rigid support is provided to the burnt part, improving its strength and rigidity. This prevents the damaged part of the spray gun pipe 1 from bending or deforming during movement, thereby preventing deformation and damage to the coal pipe and protecting its integrity.

[0044] Example 2:

[0045] See Figure 1 Based on Embodiment 1, optionally, the circumferential joint ends of the first semi-circular hoop 2 and the second semi-circular hoop 3 are respectively provided with connecting plates 5, and bolts 6 are passed through the connecting plates 5 so that the first semi-circular hoop 2 and the second semi-circular hoop 3 can be detachably connected and fixed.

[0046] Specifically, the connecting plate 5 is integrally formed with the first semi-circular hoop 2 and the second semi-circular hoop 3 to enhance the structural strength. Each semi-circular hoop is provided with two connecting plates 5, and each connecting plate 5 has two screw holes. The first semi-circular hoop 2 and the second semi-circular hoop 3 are detachably connected and fixed to the burnt position of the spray gun pipe 1 by four bolts 6.

[0047] The detachable connection facilitates the disassembly and replacement of the clamps, eliminating the need for complex processes. Tightening or loosening can be accomplished with a wrench, significantly reducing assembly time. Furthermore, the detachable connection structure is simple, easy to manufacture, and cost-effective. In addition, bolted connections are effectively protected against loosening under vibration or load through anti-loosening measures (such as spring washers and self-locking nuts), ensuring long-term safety.

[0048] Example 3:

[0049] See Figure 2 and Figure 3 Based on the above embodiments, optionally, one of the connecting plates 5 is provided with a mounting groove 7, a spring 8 is provided in the mounting groove 7, and a T-shaped limiting block 9 is connected to the lower end of the spring 8;

[0050] The T-shaped limiting block 9 is slidably connected to the inner wall of the mounting groove 7, so that the spring 8 can drive the T-shaped limiting block 9 to move up and down in the mounting groove 7 along its height direction.

[0051] Specifically, the top of the spring 8 is fixed in the mounting groove 7, the bottom of the spring 8 is fixedly connected to the horizontal section of the T-shaped limiting block 9, and the T-shaped limiting block 9 is slidably connected to the inner wall of the mounting groove 7. This arrangement allows the spring to pull the T-shaped limiting block 9 upward along its height direction within the mounting groove 7 when compressed; and to push the T-shaped limiting block 9 downward along its height direction within the mounting groove 7 when the spring returns to its original position.

[0052] Optionally, the lower end of the mounting groove 7 is provided with a sliding hole that allows the vertical section of the T-shaped limiting block 9 to pass through, and a slot 10 is provided below the mounting groove 7;

[0053] When the spring 8 is in its natural state, the vertical section of the T-shaped limiting block 9 extends into the slot 10 through the sliding hole.

[0054] Specifically, the upper end of the mounting groove 7 is closed, and the lower end has a sliding hole. The size of the sliding hole is adapted to the size of the vertical section of the T-shaped limiting block 9. The vertical section of the T-shaped limiting block 9 does not contact or slides in contact with the inner wall of the sliding hole, so that when the spring is compressed, it pulls the vertical section of the T-shaped limiting block 9 to rise away from the slot 10; when the spring is reset, it pushes the vertical section of the T-shaped limiting block 9 to descend towards the slot 10 until it extends into the slot 10.

[0055] The horizontal section of the T-shaped limiting block 9 is larger than the sliding hole size, so that the lower end of the mounting groove 7 limits the T-shaped limiting block 9 and prevents the T-shaped limiting block 9 from falling beyond the specified length.

[0056] Optionally, a T-shaped locking strip 11 is provided on the side wall of another connecting plate 5, and the hook end of the T-shaped locking strip 11 extends into the locking groove 10 and is engaged with the vertical section of the T-shaped limiting block 9.

[0057] Specifically, the non-hook end of the T-shaped locking strip 11 is fixed to the side wall of the connecting plate 5. By applying force to the connecting plate 5, the hook end of the T-shaped locking strip 11 extends into the locking groove 10 and abuts against the front side of the vertical section of the T-shaped limiting block 9, causing the spring 8 to compress and pull the T-shaped limiting block 9 upward. With continued application of force, the hook end of the T-shaped locking strip 11 extends into the rear side of the vertical section of the T-shaped limiting block 9. At this time, the spring 8 returns to its original position and pushes the T-shaped limiting block 9 downward, so that the hook end of the T-shaped locking strip 11 and the vertical section of the T-shaped limiting block 9 are engaged, thereby realizing the snap-fit ​​connection between the first semi-circular arc hoop 2 and the second semi-circular arc hoop 3.

[0058] In this embodiment, the first semi-circular hoop 2 and the second semi-circular hoop 3 are connected by a snap-fit, which can be achieved by manually pressing. Compared with bolt connection, no tools such as wrenches are needed, which greatly improves assembly efficiency.

[0059] Optionally, the vertical section of the T-shaped limiting block 9 and the hook end of the T-shaped locking strip 11 are provided with bevels.

[0060] Specifically, the beveled design can disperse the force when pressing and reduce the mechanical resistance when engaging; the inclined surface makes the T-shaped locking strip 11 and the T-shaped limiting block 9 form line contact or surface contact when engaging, rather than point contact, thereby dispersing local stress.

[0061] Optionally, the axis of the spray gun pipe 1 coincides with the axis of the clamp body formed by the first semi-circular arc hoop 2 and the second semi-circular arc hoop 3.

[0062] Specifically, the coaxial design can avoid vibration caused by eccentricity, reduce the damage caused by vibration to the burnt parts of the spray gun tube 1, thereby preventing the situation from deteriorating and ensuring the integrity of the coal pipe inside the spray gun tube 1.

[0063] It should be noted that the structures and / or installation methods not detailed in this application are those that can be known by those skilled in the art in combination with common knowledge and / or prior art, and are not the focus of this application, and will not be elaborated further here.

[0064] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this application; the dimensions of the drawings are not related to the specific physical object, and the physical object dimensions can be arbitrarily changed.
