Description

Technical Field

[0001] This utility model relates to the field of groove processing technology, and in particular to a suspension device for painting grooved pipe fittings. Background Technology

[0002] Grooved pipe fittings are accessories used to connect pipes. Through grooved connections, they enable rapid pipe installation and offer advantages such as convenient construction and easy disassembly. They are widely used in fire protection, water supply and drainage, chemical, petroleum, gas, and other engineering fields. Painting the surface of the fittings with paint creates a dense coating, extending their service life. Before painting, it is essential to thoroughly remove oil, impurities, and rust from the surface. This can be done using organic solvents, alkaline solutions, or sandblasting. Then, select a suitable paint based on the fitting's operating environment and requirements. After painting, allow the fittings to air dry naturally in a well-ventilated environment and cure according to the paint's specifications.

[0003] When painting grooved pipe fittings, a suspension device is needed to assist in the painting operation. The grooved pipe fittings are suspended and fixed to keep them stable during the painting process, while also facilitating uniform spraying and improving painting efficiency and quality. Existing grooved pipe fitting painting suspension devices mostly adopt multi-layer rotating brackets, with each layer equipped with a rotating joint. The pipe fittings are controlled to rotate around a vertical axis by manual knobs, gear racks and pinions.

[0004] Although its angle adjustment range is clear and precise positioning can be achieved through a dial or limit block, manual adjustment is time-consuming and has a low degree of automation. In addition, it can only adjust the rotation of the pipe around the vertical axis, but cannot adjust the vertical tilt rotation of the pipe, which reduces its practicality and narrows its applicable range. Summary of the Invention

[0005] The purpose of this utility model is to provide a suspension device for painting grooved pipe fittings, which solves the problems of time-consuming manual adjustment, low degree of automation, and the inability to adjust the pipe fittings to rotate around the vertical axis, thus reducing practicality and narrowing the scope of application.

[0006] To achieve the above objectives, this utility model provides a suspension device for painting grooved pipe fittings. The suspension device for painting grooved pipe fittings includes a base, an adjustment mechanism fixedly connected to the top of the base, the adjustment mechanism being used to adjust the lifting angle and to fold the device, and a leveling mechanism fixedly connected to the outer wall of the base, the leveling mechanism being used to adjust the horizontal position of the entire device during installation.

[0024] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0025] Please see the appendix Figure 1 - Appendix Figure 3 An embodiment of this utility model is provided: a suspension device for spraying paint on grooved pipe fittings, including a base 1, an adjustment mechanism 2 fixedly connected to the top of the base 1, the adjustment mechanism 2 is used to adjust the lifting angle and can fold the device, and a leveling mechanism 3 is fixedly connected to the outer wall of the base 1, the leveling mechanism 3 is used to adjust the horizontal position of the entire device during installation.

[0026] The adjustment mechanism 2 includes a support column 201, the bottom end of which is fixedly connected to the top of the base 1. A sliding sleeve 205 is provided on the outer wall of the support column 201, which slides along the support column 201 to adjust the suspension height. A boom 202 is rotatably connected to the outer wall of the sliding sleeve 205, and a pull arm 203 is rotatably connected to the top of the boom 202. A fixing plate 212 is fixedly connected to the middle of the outer wall of the sliding sleeve 205, and a rotating shaft is rotatably connected to the inner wall of the fixing plate 212. 214. The boom 202 is used to support and install the grooved pipe fittings to be painted. A fixed plate 206 is fixedly connected to the rear end of the rotating shaft 214, and a bevel gear 207 is fixedly connected to the front end of the rotating shaft 214. The bevel gear 207 is used to transmit power from the rest of the structure. A sliding plate 211 is provided on the outer wall of the rotating shaft 214. Multiple locking teeth 208 are fixedly connected to adjacent sides of the sliding plate 211 and the fixed plate 206. The locking teeth 208 are used to rotate the sliding plate 211 and the fixed plate 206. For limiting the movement, a fixing plate 210 is fixedly connected to the outer wall of the sliding sleeve 205 near its edge. A moving component 209 is fixedly connected to the rear side of the fixing plate 210. A suspension component 204 is provided at the bottom of the boom 202. The fixing plate 210 is used to support and install the moving component 209. A drive component 213 is fixedly connected to the front side of the sliding sleeve 205. The middle part of the outer wall of the rotating shaft 214 is fixedly connected to the outer wall of the pull arm 203. The rotation of the rotating shaft 214 can drive the rotation of the pull arm 203. The front side of the fixed plate 210 is fixedly connected to the rear side of the fixed plate 206. The moving component 209 includes a hydraulic rod 2093. The front end of the hydraulic rod 2093 is fixedly connected to the rear side of the fixed plate 210. The rear end of the hydraulic rod 2093 is fixedly connected to a connecting plate 2092. The hydraulic rod 2093 is used to push the connecting plate 2092 to move back and forth. A plurality of connecting rods 2091 are fixedly connected to the front side of the connecting plate 2092 near the edge. The connecting plate 2092 can drive the plurality of connecting rods 2091 to move synchronously.

[0027] Specifically, when the angle of the boom 202 needs to be adjusted, the sliding plate 211 is moved backward by the moving component 209, disengaging from the fixed plate 206. At this time, the rotating shaft 214 can rotate freely. The rotating bevel gear 207 drives the rotating shaft 214 and the fixed plate 206 to rotate, thereby adjusting the angle of the pull arm 203 and the boom 202. After the angle adjustment is completed, the sliding plate 211 is moved forward by the moving component 209, re-engaging with the fixed plate 206 and locking the angle of the boom 202. The main function of the boom 202 is to support and install the grooved pipe fittings to be painted. It can be designed into different structural forms according to the shape and size of the pipe fittings. The pull arm 203 is connected to the subsequent adjustment components. The movement of the pull arm 203 drives the boom 202 to adjust its angle. The suspension height can be flexibly adjusted by the up and down movement of the sliding sleeve 205 to adapt to the painting operation of grooved pipe fittings of different lengths and sizes.

[0028] Please see the appendix Figure 2 - Appendix Figure 4 The leveling mechanism 3 includes a positioning plate 307. Multiple positioning plates 307 are fixedly connected to the outer wall of the base 1. The positioning plates 307 are used to install and connect the remaining structures. The inner wall of the positioning plate 307 is provided with a sliding groove 305. The inner wall of the sliding groove 305 is provided with a guide groove 306. The inner wall of the guide groove 306 is slidably connected with a collar 304. The inner wall of the collar 304 is slidably connected with a sliding column 301. The guide groove 306 is used to guide the collar 304 to slide within it. The inner wall of the collar 304 is threaded with multiple lead screws 303 near the edge. The outer wall of the sliding column 301 is provided with multiple slots 302. The lead screws 303 can drive the collar 304 to move by rotation. The bottom end of the sliding column 301 is fixedly connected with an installation component 308. The outer wall of the lead screw 303 is fixedly connected with an auxiliary component 309. The slots 302 can engage with the collar 304.

[0029] Specifically, the guide groove 306 restricts the movement direction of the collar 304, allowing it to slide only along a predetermined path. This ensures the accuracy and stability of the leveling process, prevents the collar 304 from shifting or wobbling during movement, and ensures that the leveling mechanism can work in a predetermined manner. By simultaneously rotating multiple lead screws 303, the movement direction and distance of the collar 304 can be controlled, thereby adjusting the position of the sliding column 301.

[0030] Please see the appendix Figure 3 - Appendix Figure 5 The drive assembly 213 includes an asynchronous motor 2131, which is fixedly connected to the front side of the sliding sleeve 205. The asynchronous motor 2131 provides power to the entire device. The output end of the asynchronous motor 2131 is fixedly connected to a bevel gear 2132. The mounting assembly 308 includes a mounting plate 3081. The bevel gear 2132 is used to transmit the rotation of the asynchronous motor 2131. The mounting plate 3081 is fixedly connected to the bottom end of the sliding column 301. The inner wall of the mounting plate 3081 is threaded with multiple bolts 3082, which can fix the mounting plate 3081 in the required position.

[0031] Specifically, bevel gear 2132 meshes with bevel gear 207 in adjustment mechanism 2, transmitting the rotational motion of asynchronous motor 2131 to bevel gear 207. This effectively transmits the power of asynchronous motor 2131 to subsequent adjustment components, enabling precise adjustment of the boom 202 angle. Through the combined action of multiple bolts 3082, mounting plate 3081 is firmly fixed to the ground, thus providing stable support for the entire suspension device.

[0032] Please see the appendix Figure 2 - Appendix Figure 4The suspension assembly 204 includes a guide rail 2042, which is located at the bottom of the boom 202. A lifting block 2041 is slidably connected to the inner wall of the guide rail 2042. The guide rail 2042 is used to guide the lifting block 2041 to slide within it. The auxiliary assembly 309 includes a butterfly handle 3091, which is fixedly connected to the outer wall of the lead screw 303. A buffer pad 3092 is fixedly connected to the inner wall of the collar 304. The butterfly handle 3091 is used to help the user rotate the lead screw 303.

[0033] Specifically, the butterfly handle 3091 has a larger gripping area, which can reduce the pressure on the operator's hands and improve the comfort of operation. This allows the operator to complete the operation by simply turning the butterfly handle 3091 with their hands without the need for additional tools. The buffer pad 3092 can also increase the friction between the collar 304 and the slot 302, improve the stability of the engagement, and prevent the collar 304 from loosening due to vibration during the operation of the device.

[0034] Working principle: When it is necessary to adjust the angle of the boom 202, or to fold the boom 202 and the tie rod 203, the hydraulic rod 2093 is first activated to push the connecting plate 2092, which in turn drives multiple connecting rods 2091 to pull the sliding plate 211. This causes the locking teeth 208 on the outer wall of the sliding plate 211 to disengage from the locking teeth 208 on the outer wall of the fixed plate 206. After complete disengagement, the asynchronous motor 2131 is activated to drive the second bevel gear 2132 to rotate, which in turn drives the first bevel gear 207 to rotate. This allows the fixed plate 206 to simultaneously drive the boom 202 and the fixed plate 206 to rotate. The rotation of the boom 202 will drive the pull arm 203 to rotate up and down. When the pull arm 203 is completely in contact with the outer wall of the base 1, the pull arm 203 and the boom 202 are folded. After the angle adjustment is completed, the hydraulic rod 2093 is activated in the opposite direction to push the connecting plate 2092 to drive the connecting rod 2091 and the sliding plate 211 to move. The sliding plate 211 and the fixed plate 206 are mutually limited by the locking teeth 208.

[0035] When the base 1 needs to be installed, first place the base 1 and the mounting plate 3081 on the ground, then fix the mounting plate 3081 in the required position with bolts 3082. Then rotate the screw 303 to drive the collar 304 to slide in the guide groove 306, so that the collar 304 can disengage from the inner wall of the slot 302. Adjust the height of one side of the base 1 up and down along the sliding column 301. After reaching the appropriate position, rotate the screw 303 to drive the collar 304 to slide in the guide groove 306, thereby locking the collar 304 in the inner wall of the slot 302 and limiting the sliding of the sliding column 301.

[0036] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
