Description

Technical Field

[0001] The utility model relates to the technical field of tracing cable maintenance, in particular to a on-site maintenance fixing device for tracing cables. Background Art

[0002] In nuclear power plants, armored electric tracing cables are used to trace pipelines such as boric acid pipelines, sodium solution pipelines, chilled water, instrument pipelines and other special process pipelines to maintain the fluid temperature and prevent crystallization or freezing of boric acid, sodium solution and other fluid media. The electric tracing system plays an important role in maintaining the safe and stable operation of nuclear power units. At present, the laying and removal operation processes of electric tracing cables in nuclear power plants are relatively cumbersome and have many processes, resulting in great difficulty in quality control of the laying and removal processes of electric tracing cables, and long construction and installation time. The on-site maintenance technology of armored tracing cables can greatly save the maintenance cost of armored tracing cables and labor costs.

[0003] Armored tracing cables are mainly installed on pipelines and tanks. When the armored tracing cable is damaged and needs on-site maintenance, the damaged part of the armored tracing cable needs to be repaired. During the repair, the damaged position of the tracing cable needs to be patched, cut and welded, and the joints need to be dug and polished and injected with glue, etc. During the repair operation, the joints are usually fixed and clamped manually. This operation method brings great inconvenience to the repair work of armored tracing cables and poses certain potential safety hazards to the repair quality.

[0004] Due to the complex on-site environment, if components such as joints cannot be fixed, it will cause certain obstacles to the operation of operators during the welding process, making it impossible for operators to effectively fix the welding points of components such as joints during the welding process, thus affecting the welding efficiency and causing the work to be unable to proceed normally or increasing the ineffective workload. In addition, the lack of effective fixing measures will also cause misalignment of the welding points during the welding process, thus affecting the stability of the welding quality and resulting in the appearance of welding defects, such as loosening or fracture of the welding points. Therefore, it is crucial to effectively fix the components to be welded during the welding process. Summary of the Utility Model

Description of the Drawings

[0022] The present utility model will be further described below in conjunction with the drawings and embodiments. In the drawings:

[0023] Figure 1 is a schematic perspective view of a field maintenance fixing device for a tracing cable according to an embodiment of the present utility model. Specific embodiments

[0024] For a clearer understanding of the technical features, objectives, and effects of the present utility model, the specific embodiments of the present utility model will now be described in detail with reference to the drawings.

[0025] As shown in Figure 1 a field maintenance fixing device for a tracing cable according to an embodiment of the present utility model may include a fixed base 10, a support rod 20, and a fixed clamp 30. The fixed base 10 is used to fix the entire field maintenance fixing device for the tracing cable to a position such as an operating table. The support rod 20 is connected between the fixed base 10 and the fixed clamp 30. The fixed clamp 30 is used to clamp the tracing cable to fix the tracing cable, facilitating operations such as repair, cutting, and welding of the tracing cable by the staff.

[0026] Among them, the fixed base 10 serves as the support structure of the entire device, realizing the positioning of the entire device at positions such as an operating table, making installation more convenient in complex environments. Moreover, the fixed base 10 has a certain weight to support components such as the support rod 20 and the fixed clamp 30 above, avoiding problems such as the entire device tipping over.

[0027] The form of the fixed base 10 is not limited, and in terms of shape, it can be but is not limited to circular, polygonal, etc.

[0028] As an option, the fixed base 10 can be a magnetic fixing base, which can be magnetically adsorbed on a metal or magnetic platform. Of course, the fixed base 10 can also be positioned at positions such as an operating table by sufficient weight; or, the fixed base 10 can also be fixed at positions such as an operating table through a connection component (such as a bolt, etc.) or a clamping method.

[0029] When the fixed base 10 is a magnetic fixing base, as shown in Figure 1 it may include a magnetic base main body 11, a fixed handle 12, and a release buckle 13 provided on the magnetic base main body 11 in terms of structure. The release buckle 13 is rotatable relative to the fixed handle 12, so as to drive the release buckle 13 to approach or reset to the fixed handle 12, enabling the magnetic base main body 11 to generate or cancel magnetic force. For example, when the release buckle 13 is pinched (pinched in the direction of the fixed handle 12) once, the magnetic base main body 11 generates magnetic force, and when the release buckle 13 is pinched again, the magnetic force of the magnetic base main body 11 disappears.

[0030] Understandably, the principle of magnetic force generation of the magnetic fixing base is realized by the prior art and will not be elaborated here.

[0031] In the longitudinal direction of the support rod 20, the support rod 20 has opposite first and second ends. The first end of the support rod 20 is connected to the fixed base 10, and the fixed clamp 30 is connected to the second end of the support rod 20.

[0032] To meet the requirements of different positions and angles on-site, the support rod 20 is rotatable relative to the fixed base 10, so that the orientation of the support rod 20 on the fixed base 10 can be adjusted, and thus the orientation of the fixed clamp 30 can also be adjusted.

[0033] To rotatably connect the support rod 20 to the fixed base 10, the field maintenance fixing device for the tracing cable further includes a first swivel joint 40. The first end of the support rod 20 is connected to the fixed base 10 through the first swivel joint 40. The rotation angle of the support rod 20 relative to the fixed base 10 through the first swivel joint 40 can be greater than 180°, and can also approach 360°, achieving angle adjustment to the greatest extent.

[0034] Specifically, one joint end of the first swivel joint 40 is connected to the first end of the support rod 20, and the other joint end of the first swivel joint 40 can be connected to the fixed base 10 through components such as a rod section and a screw.

[0035] The first swivel joint 40 can be, but is not limited to, a ball universal joint, or a component of a ball and a spherical concave fixture cooperating with a butterfly bolt.

[0036] In some embodiments, the length of the support rod 20 can be set according to actual needs. To meet the requirements of different lengths of the support rod 20, the support rod 20 is preferably a telescopic rod body, so that the support rod 20 can be stretched when a larger length is needed, and the support rod 20 can be contracted when a shorter length is needed. For the telescopic rod body, it can be formed by the cooperation of multiple pipe bodies with snap connections; or, the telescopic rod body can be realized by using a bellows with sufficient strength, such as a metal bellows.

[0037] As Figure 1 In the illustrated embodiment, the support rod 20 may further include a first rod body 21, a second rod body 22, and a third swivel joint 23. The first rod body 21 is connected to the fixed base 10, and the fixed clamp 30 is connected to the second rod body 22; the third swivel joint 23 is connected between the first rod body 21 and the second rod body 22, so that the first rod body 21 and the second rod body 22 can rotate relative to each other. The two can not only be in a straight line, but also be joined at an angle, thereby increasing the angle adjustment directions of the support rod 20 and the fixed clamp 30.

[0038] It is rotatable between the first rod body 21 and the second rod body 22, suitable for operation in small spaces and meeting the angle adjustment requirements of small spaces.

[0039] The third steering joint 23 can be, but is not limited to, a ball joint, or a component of a ball and a spherical concave fixture cooperating with a butterfly bolt.

[0040] Furthermore, to meet the need for adjustable length, at least one of the first rod body 21 and the second rod body 22 can be set as a telescopic rod body.

[0041] The fixed fixture 30 is connected to the second end of the support rod 20 for clamping the traced heating cable to be repaired, meeting the fixation of traced heating cables with different diameters. As required, to meet the orientation adjustment of the fixed fixture 30 on the support rod 20, the fixed fixture 30 can rotate relative to the support rod 20 at the second end of the support rod 20.

[0042] To enable the fixed fixture 30 to be rotatably connected to the second end of the support rod 20, the on-site repair and fixation device for the traced heating cable can further include a second steering joint 50; the fixed fixture 30 is connected to the second end of the support rod 20 through the second steering joint 50. The rotation angle of the fixed fixture 30 relative to the support rod 20 through the second steering joint 50 can be greater than 180°, and can also approach 360°, achieving angle adjustment to the greatest extent.

[0043] The second steering joint 50 can be, but is not limited to, a ball joint, or a component of a ball and a spherical concave fixture cooperating with a butterfly bolt.

[0044] In some embodiments, the fixed fixture 30 can specifically include a first clip 31 and a second clip 32 arranged oppositely, and an adjustable bolt 33 connected between the first clip 31 and the second clip 32; the first clip 31 and the second clip 32 are connected in an openable and closable manner through the adjustable bolt 33.

[0045] To position the traced heating cable, arc-shaped grooves capable of fitting with the outer surface of the traced heating cable are respectively provided on the opposite surfaces of the first clip 31 and the second clip 32. When the traced heating cable is placed between the first clip 31 and the second clip 32, the traced heating cable is placed in the arc-shaped groove, and the adjustable bolt 33 is rotated to drive the first clip 31 and the second clip 32 to move towards each other to clamp the traced heating cable in the arc-shaped groove.

[0046] To facilitate the rotation of the adjustable bolt 33 without the aid of tools, the adjustable bolt 33 is preferably a butterfly bolt. It can be understood that the adjustable bolt 33 can also be a conventional cylindrical bolt, and can be tightened with the aid of tools such as a wrench as required.

[0047] When the on-site maintenance fixing device for the tracing cable of the utility model is in use, the whole device is fixed on the operating table through the fixing base 10. The tracing cable to be repaired is fixed on the fixing clamp 30. According to the operation needs, the fixing clamp 30 and / or the support rod 20 are rotated to position the tracing cable at an angle convenient for operation, and the staff performs repair operations such as welding and cutting on the tracing cable. During the repair process, the tracing cable will not move or shake, avoiding the movement of the welding point during the welding process, the virtual soldering or falling off of the welding point due to the jitter generated by the manual butt joint of the welding point, which affects the welding quality.

[0048] The above are only the embodiments of the utility model, and do not limit the patent scope of the utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the utility model, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the utility model by the same token.
