Description

Technical Field

[0001] This utility model belongs to the field of auxiliary equipment for pipe welding, and specifically relates to a support device for grinding pipe fittings. Background Technology

[0002] In petrochemical pipeline systems, the welded joints of pipe fittings (such as elbows, flanges, and tees) typically require grinding to remove weld slag, oxide layers, and surface irregularities. This improves weld quality, ensures sealing, and meets the requirements of subsequent anti-corrosion or coating processes. Furthermore, grinding reduces stress concentration and extends the service life of the fittings. Therefore, weld grinding is one of the key procedures in pipeline fabrication and installation.

[0003] Traditional grinding methods typically involve manual positioning or using simple clamps to secure pipe fittings. Simple clamps are only suitable for specific types of pipe fittings (such as straight pipes). For pipe fittings with complex structures (such as elbows or tees), they lack effective clamping and support, which can cause the pipe fittings to shake or even fall off during grinding, posing a safety hazard.

[0004] Therefore, we propose a grinding pipe support device to solve the above problems. Utility Model Content

[0005] To address the problem that simple clamps are only suitable for specific types of pipe fittings (such as straight pipes) and lack effective clamping and support for pipe fittings with complex structures (such as elbows or tees), this utility model provides a pipe fitting support device for grinding.

[0006] The solution adopted by this utility model to solve its technical problem is: a grinding pipe support device, including a support base, an adjusting base, a fixing component, a sliding sleeve and an adjusting assembly. The adjusting base is arranged laterally on the side of the support base and perpendicular to the support base. Its top is used to place the pipe. The adjusting base and the support base are detachably connected by the fixing component.

[0007] The sliding sleeve is fitted on the outside of the adjusting seat and can slide laterally along the adjusting seat. A fixing plate is welded and fixed to the top of the adjusting seat, and a clamping plate is welded and fixed to the top of the sliding sleeve.

[0008] The adjustment assembly is installed between the fixed plate and the clamping plate to adjust the position of the clamping plate and the sliding sleeve.

[0009] Preferably, the top of the support base is provided with a V-shaped groove for placing the pipe fitting.

[0010] Preferably, the support base has multiple through holes from top to bottom, and the right end of the adjusting base has two threaded grooves corresponding to the positions of the through holes.

[0011] Preferably, the fixing member is a positioning bolt, the end of which passes through a through hole and is threadedly connected to the corresponding threaded groove.

[0012] Preferably, a rectangular hole is provided at the left end of the adjusting seat, and a guide rod is provided inside the rectangular hole.

[0013] Preferably, a T-shaped rod is welded and fixed to the side of the support base, and the bottom end of the guide rod is welded and fixed to the top of the T-shaped rod.

[0014] Preferably, the adjusting assembly includes an adjusting screw and a nut mounted on a fixed plate. The adjusting screw and the nut are threaded together, and a bearing is fitted onto the optical axis end of the adjusting screw, which is mounted on a clamping plate.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please see Figure 1-4 This utility model provides a technical solution for a grinding pipe support device:

[0027] Example 1:

[0028] according to Figure 1-4 As shown, it includes a support base 1, an adjusting base 2, a fixing member, a sliding sleeve 41, and an adjusting assembly. The top of the support base 1 is provided with a V-shaped groove for placing pipe fittings. The support base 1 is provided with multiple through holes 11 from top to bottom. The adjusting base 2 is arranged laterally on the side of the support base 1 and is perpendicular to the support base 1. Its top is used to place pipe fittings. The adjusting base 2 supports the bottom end of the pipe fittings, and the V-shaped groove supports the horizontal section of the pipe fittings.

[0029] Two threaded grooves are provided on the right end of the adjusting seat 2 corresponding to the through hole 11. There are two fixing parts, namely positioning bolts 5. The end of the positioning bolts 5 passes through the through hole 11 and is threadedly connected to the corresponding threaded grooves to connect and fix the adjusting seat 2. By removing the positioning bolts 5, the height of the adjusting seat 2 can be quickly adjusted according to the size of the pipe fitting, adapting to different sizes of pipe fittings and enhancing the versatility and ease of operation of the device.

[0030] The sliding sleeve 41 is fitted on the outside of the adjusting seat 2 and can slide laterally along the adjusting seat 2. A fixing plate 43 is welded and fixed to the top of the adjusting seat 2, and a clamping plate 45 is welded and fixed to the top of the sliding sleeve 41. The adjusting assembly includes an adjusting screw 44 and a nut 42 installed on the fixing plate 43. The adjusting screw 44 and the nut 42 are threadedly connected, and a bearing is fitted on its optical shaft end. The bearing is installed on the clamping plate 45. By rotating the adjusting screw 44 in the forward direction, the position of the sliding sleeve 41 and the clamping plate 45 is adjusted, and the pipe is clamped and fixed between the clamping plate 45 and the support seat 1, ensuring that the pipe is firmly fixed during the grinding process and improving the grinding accuracy.

[0031] A rectangular hole is provided at the left end of the adjusting seat 2, and a guide rod 31 is installed in the rectangular hole. A T-shaped rod 32 is welded and fixed to the side of the support seat 1. The bottom end of the guide rod 31 is welded and fixed to the top of the T-shaped rod 32. The guide rod 31 guides the adjusting seat 2, improving the stability of the adjusting seat 2 during use. The T-shaped rod 32 connects the guide rod 31 and the support seat 1, further enhancing the stability of the overall structure.

[0032] In practical use, the present invention provides a grinding pipe support device. First, according to the specifications and size of the pipe, loosen and remove the two positioning bolts 5, move the adjusting seat 2 up and down so that the top of the adjusting seat 2 and the V-shaped groove on the top of the support seat 1 form a suitable support space for the pipe. Then, select the through hole 11 of the corresponding height, re-insert the positioning bolts 5 and tighten them to fix the position of the adjusting seat 2.

[0033] Place the horizontal section of the pipe fitting in the V-groove of the support seat 1, and place the bottom end on the top of the adjusting seat 2. Rotate the adjusting screw 44 in the forward direction to adjust the position of the sliding sleeve 41 and the clamping plate 45, and clamp and fix the pipe fitting between the clamping plate 45 and the support seat 1 to ensure that the pipe fitting is firmly fixed during the grinding process. Finally, the worker holds the grinding equipment and processes the fixed pipe fitting.

[0034] Example 2:

[0035] Based on Example 1, such as Figure 1 and Figure 2 As shown, it also includes four trapezoidal blocks 46. The four trapezoidal blocks 46 are welded and fixed in pairs to the top of the adjusting seat 2 and the right side of the clamping plate 45 respectively. The inclined surface of the trapezoidal blocks 46 is in contact with the outer wall of the pipe fitting, forming a multi-point contact support, which further improves the stability of clamping.
