DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments of the present application.

For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0027] A steel bar sleeve spraying device, as shown in Figure 1 and Figure 2 shown, comprising one or more spraying chambers 1, further comprising a conveying mechanism 4 and a heating mechanism 3, the spraying chamber 1 is provided with an opening 8 on both sides of the side wall, the conveying mechanism 4 passes through the opening 8 and is connected in series with all the stations, the conveying mechanism 4 is provided with a connecting piece 7 for fixing the steel bar sleeve 5, the connecting piece 7 is detachably connected with the conveying mechanism 4, the heating mechanism 3 is located at the starting end of the conveying mechanism 4 and is used for heating the steel bar sleeve 5, and the conveying mechanism 4 is used for conveying the heated steel bar sleeve 5 to the spraying chamber 1.

[0028] The spraying chamber 1 is made of metal material, has good wear resistance and corrosion resistance, and can withstand chemical substance erosion and mechanical wear in the spraying process. The openings 8 formed on the two side walls of the spraying chamber 1 are matched with the conveying mechanism 4 in size, and the openings 8 are formed in the vertical direction to ensure that the reinforcing sleeve 5 can pass through smoothly. In actual application, the spraying chamber 1 can be provided with one or more according to production needs, and two spraying chambers 1 are provided in the embodiment, the openings 8 of which are aligned and connected with each other, so that the conveying mechanism 4 can pass through all the spraying chambers 1, and the continuous spraying operation of the reinforcing sleeve 5 is realized.

[0029] The embodiment also includes two upright columns 9, which are respectively fixed to the ground on the two sides of the spraying chamber 1 and are made of steel material, have sufficient strength and stability, and are used to support the synchronous wheel 402 group and the motor 403. The reinforcing ribs 10 are connected between the upright columns 9 and the spraying chamber 1, the two ends of the reinforcing ribs 10 abut against the upright columns 9 and the spraying chamber 1 respectively, and are fixed by welding or bolts, thereby enhancing the stability of the whole equipment and preventing shaking and tilting during operation.

[0030] The conveying mechanism 4 is composed of a belt 401, a synchronous wheel 402 group and a motor 403. The belt 401 is made of high-temperature-resistant rubber material, which can stably run near the heating process without deformation. The synchronous wheel 402 group includes a driving wheel and a driven wheel, the driving wheel is fixed to the output shaft of the motor 403, and the motor 403 is installed on the side wall of one of the upright columns 9, and the driven wheel is rotatably connected to the other upright column 9. The motor 403 drives the driving wheel to rotate when working, and drives the driven wheel to rotate through the belt 401, thereby realizing the running of the belt 401. The belt 401 is uniformly provided with a plurality of hanging rings 6, and the connecting piece 7 is detachably connected with the hanging ring 6 through the hook 702, so that the connecting piece 7 can move with the conveying of the belt 401. The upper and lower parts of the hanging ring 6 can rotate relative to each other, so that the worker can manually rotate the connecting piece 7.

[0031] In other embodiments, the conveying mechanism 4 can also be composed of a chain, a synchronous chain wheel group and a motor 403, and the hanging ring 6 is fixed on the chain.

[0032] The heating mechanism 3 is arranged on one side of the spraying chamber 1, that is, below the starting end of the belt 401. The heating mechanism 3 includes an induction heating coil 301, which adopts a multi-layer dense winding structure, and can uniformly heat the reinforcing sleeve 5. After the worker fixes the reinforcing sleeve 5 on the connecting piece 7, the reinforcing sleeve 5 is manually placed in the heating coil 301, heat is generated through electromagnetic induction principle, so that the reinforcing sleeve 5 reaches the required temperature for spraying. The power and heating time of the heating coil 301 can be adjusted according to the material and size of the reinforcing sleeve 5, so as to ensure the heating effect.

[0033] As Figure 3 WithFigure 4 As shown, the connecting piece 7 comprises a connecting column 701, a hook 702, a supporting claw 703, an upper sealing piece 704 and a lower sealing piece 705. The connecting column 701 is made of high-temperature-resistant heat-insulating material, and has a thermal conductivity lower than 0.5 W / (m·K), which can effectively prevent heat conduction and facilitate the worker's grasping operation. In the embodiment, the connecting column 701 is made of nylon material. The supporting claw 703 is arranged at the bottom of the connecting column 701. A rotating shaft is arranged on the column extending downward from the bottom of the connecting column 701. The supporting claw 703 is rotatably connected to the rotating shaft and is provided with a torsional spring. When the connecting piece 7 penetrates into the steel sleeve 5, the supporting claw 703 rotates upward against the elastic force of the torsional spring. After the supporting claw 703 enters, it has a tendency to open outward under the action of the torsional spring, so as to abut against the inner wall of the steel sleeve 5, thereby achieving the firm fixation of the connecting piece 7 and the steel sleeve 5.

[0034] When the steel sleeve 5 is removed, the connecting piece 7 needs to be inverted. The steel sleeve 5 slides out from the top of the connecting piece 7, that is, from the side of the hook 702 under the action of gravity. The maximum width of the hook 702 is less than or equal to the diameter of the connecting column 701.

[0035] The upper sealing piece 704 and the lower sealing piece 705 are arranged above and below the supporting claw 703, respectively, and are made of flexible material resistant to high temperature and paint, such as rubber material. When the steel sleeve 5 is installed in place, it can just block the upper and lower ends of the steel sleeve 5, so as to prevent the epoxy resin paint from entering the inside of the steel sleeve 5 during the spraying process.

[0036] Working process:

[0037] The worker first fixes the steel sleeve 5 on the connecting piece 7. The supporting claw 703 of the connecting piece 7 is opened by the torsional spring and abuts against the inner wall of the steel sleeve 5. The upper sealing piece 704 and the lower sealing piece 705 block the upper and lower ports of the steel sleeve 5. Then the steel sleeve 5 together with the connecting piece 7 is placed into the induction heating coil 301. After heating, the connecting piece 7 is hung on the hanging ring 6 on the belt 401 through the hook 702. The conveying mechanism 4 conveys the steel sleeve 5 to the spraying chamber 1. The worker performs the spraying operation on the steel sleeve 5 by holding the spraying gun 2. After spraying, the steel sleeve 5 moves to the next station with the conveying mechanism 4 or completes the spraying process. The worker removes the connecting piece 7 from the hanging ring 6 and separates the steel sleeve 5 from the connecting piece 7. The separation can also be performed after the connecting piece 7 is collected for a period of time.

[0038] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. within the design concept of the present application shall be included in the protection scope of the present application.
