Technical Field
[0001] The utility model relates to the technical field of petrochemical industry, in particular to a welding-free pipeline bracket. Background Art
[0002] In the actual operation and maintenance of petrochemical equipment, necessary renovation and construction are often carried out during the non-shutdown and maintenance phase due to various production needs or to eliminate safety hazards, which mainly involves the renovation of pipelines.
[0003] Normally, these modifications are implemented during the unified shutdown and maintenance phase of the equipment. Flame welding and root support can only be carried out after the flammable and explosive media in the equipment have been drained. However, there are often urgent factors affecting production that must be rectified as soon as possible. Direct welding to the equipment poses a great safety hazard. Summary of the invention
[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a welding-free pipe bracket, which can support the pipe without welding on site under the premise of ensuring safety, and can effectively solve the problems in the background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a welding-free pipe support, comprising a support root and a support pipe portion, the support root portion comprising four clamps, the four clamps are evenly fitted on the outer side of the equipment, adjacent clamps are connected by hexagonal head bolts and hexagonal nuts, the support pipe portion comprises a channel steel, one end of the channel steel is welded to the outer side of one of the clamps, and the other end of the channel steel is connected to the branched pipe.
[0006] As a preferred technical solution of the utility model, the clamp is made by bending flat steel, and its bending angle and curvature are determined according to the equipment diameter and the tensioning gap between adjacent clamps.
[0007] As a preferred technical solution of the utility model, both ends of the clamp are bent, the bent sections of two adjacent clamps remain parallel, and each bent section is provided with double bolt holes.
[0008] As a preferred technical solution of the utility model, a spring washer is arranged between the threaded end of the hexagonal head bolt and the clamp.
[0009] As a preferred technical solution of the utility model, the connection between the channel steel and the branched pipe is of welding type or clamping type.
[0010] Compared with the prior art, the beneficial effects of the utility model are: the welding-free pipe bracket is reasonably designed and easy to operate. The equipment is tightly fitted by arranging four clamps, and the branched pipe and one of the clamps are respectively connected by arranging channel steels. The welding between the channel steels and the clamps is completed off-site. After the four clamps are sleeved on the outer side of the equipment, they are connected by hexagonal head bolts and hexagonal nuts. The bracket pipe part and the bracket root form a bracket for supporting the pipeline, which has good rigidity and strength, ensuring the safety of construction. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0015] See also Figure 1-2 The utility model provides a technical solution: a welding-free pipe bracket, including a bracket root and a bracket pipe part, the bracket root includes four clamps 1, the four clamps 1 are evenly fitted on the outer side of the equipment 7, and adjacent clamps 1 are connected by hexagonal head bolts 2 and hexagonal nuts 4. The bracket pipe part includes a channel steel 5, one end of the channel steel 5 is welded to the outer side of one of the clamps 1, and the other end of the channel steel 5 is connected to the branch pipe 6. By setting the clamp 1 to be in close contact with the surface of the equipment 7, friction is generated, so that the overall bracket is firmly rooted, and there is no need to weld with the equipment 7, thereby ensuring construction safety.
[0016] Furthermore, in order to ensure the tight fit between the clamp 1 and the device 7 , the clamp 1 is made by bending flat steel, and its bending angle and curvature are determined according to the diameter of the device 7 and the tensioning gap between adjacent clamps 1 .
[0017] Furthermore, in order to increase the tensioning force between adjacent clamps 1, both ends of the clamps 1 are bent, and the bending angle is calculated based on the diameter of the equipment 7 and the tensioning gap between the clamps 1. The bent sections of two adjacent clamps 1 remain parallel for easy assembly, and each bent section is provided with a double bolt hole.
[0018] Furthermore, a spring washer 3 is provided between the threaded end of the hexagonal head bolt 2 and the clamp 1. The spring washer 3 provides additional elastic force to make the connection tighter, thereby enhancing the shock resistance and loosening resistance of the connection and providing reliable tensioning force for the clamp 1.
[0019] Furthermore, in order to ensure the overall reliability of the bracket, the connection between the channel steel 5 and the supported pipe 6 is of welding type or clamping type.
[0020] When in use: determine the connection position of the channel steel 5 and the branch pipe 6 off-site according to the supporting position of the equipment 7, weld the other end of the channel steel 5 to one of the clamps 1, and after prefabrication off-site, transport it to the vicinity of the equipment 7 to be supported, then press the clamp 1 fixed to the channel steel 5 against the outer side of the equipment 7, install the other three clamps 1, connect the adjacent clamps 1 through the hexagonal bolts 2 and the hexagonal nuts 4, and finally complete the support of the pipeline.
[0021] The utility model can be conveniently operated, occupies less space when in use, is easy to operate and use; the bracket can be installed on the equipment 7 without stopping work or starting fire, thereby reducing economic losses and improving construction safety.
