Description

Technical Field

[0001] This utility model relates to the field of large pipe rack processing technology, specifically to an anti-tipping fixture for a large pipe rack on an oil tanker. Background Technology

[0002] In the welding and assembly of large pipe supports, especially in the welding of large pipe supports for VLCCs and 114K tankers, the pipe supports are extremely prone to tipping over during the welding process due to their large size and heavy weight. This not only affects the welding quality but also poses serious safety hazards.

[0003] Currently, the industry mainly uses the following traditional fixing methods: Method 1 often uses overhead cranes to suspend and secure the large pipe racks to prevent them from tipping over; Method 2: Use temporary pipes or angle steel and fix them to both sides of the large pipe frame by welding to achieve temporary support; Method 3 involves using temporary materials, such as wooden blocks and sandbags, to provide support from the sides of the large pipe rack.

[0004] However, all of the above-mentioned existing technical solutions have varying degrees of defects. Method 1 requires a long time to use the crane, and the number of cranes in a shipyard is limited. Long-term use of the crane is not conducive to the use of the crane in other projects or processes, and seriously affects construction efficiency. Method 2 requires welding operations on the pipe rack base material. The welding heat input will cause certain damage to the large pipe rack base material. Moreover, after welding, grinding is required, which consumes a lot of time and labor costs. Method 3 relies only on temporary items for support and lacks reliable fixing measures, resulting in poor safety. There have been many incidents of large pipe racks tipping over and injuring people due to the slippage of temporary supports, posing a serious safety hazard. Utility Model Content

[0005] To address the aforementioned issues, this application provides an anti-tipping fixture for large pipe supports on oil tankers, which solves the problems of long crane usage time, damage to the base material, and poor safety associated with existing large pipe support welding methods.

[0006] An anti-tipping fixture for a large pipe rack on an oil tanker includes a large pipe rack base material and clamping plates. The two clamping plates are symmetrically installed to clamp and fix the large pipe rack base material. The inner lining pad is fixedly installed on the inside of the clamping plate to increase the friction between the clamping plate and the main body of the large pipe rack; The upper and lower fixing tubes are fixedly installed on the diagonally opposite outer side of the clamping plate. The upper and lower fixing tubes on the same side are slidably inserted with fixing pins in the middle. The fixing pins are used to fix the two clamping plates together. The transition slope is located at the top of the inner side of the lower fixed pipe. The internal channel of the lower fixed pipe gradually narrows from top to bottom, while the inner diameter of the lower half remains unchanged.

[0007] Preferably, the two sets of upper and lower fixing tubes are installed in a staggered manner on the outside of the two clamps.

[0008] Preferably, a permanent magnet is fixedly installed on the top of the upper fixing tube to attract and fix the fixing pin.

[0009] Preferably, an adjusting rod is fixedly connected to the outside of the clamping plate, and the end of the adjusting rod is slidably sleeved with the main support frame. Preferably, the bottom of the main support frame is fixedly equipped with multiple casters, each caster having an independent brake pedal.

[0010] Preferably, the end of the adjusting rod has a threaded hole, and the outer side of the main support frame has multiple threaded holes, with a locking bolt movably installed in the middle of both threaded holes.

[0011] The beneficial effects of this utility model are as follows: The present invention describes a large pipe rack anti-tipping fixture for oil tankers, which uses two clamping plates to symmetrically clamp the large pipe rack base material and uses fixing pins to fix the two clamping plates together to form a rigid fixation of the large pipe rack, preventing the large pipe rack from tipping over and injuring people during the welding process, and improving the safety of the operation. There is no need to perform welding and grinding operations on the large pipe rack base material, which not only avoids thermal damage to the large pipe rack base material, but also saves the temporary welding tooling and subsequent grinding process, reducing labor time and construction costs. The permanent magnet installed at the top of the upper fixing tube can attract the fixing pin, preventing the fixing pin from accidentally falling off during use, thus further enhancing the reliability of the tooling. The clamping position can be flexibly adjusted according to the height requirements of different pipe racks through the sliding sleeve connection between the adjusting rod and the main support frame, and the locking bolts are used for fixing, making it highly adaptable.

[0015] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0016] Example 1: like Figure 1-4 As shown, this utility model embodiment provides an anti-tipping fixture for a large pipe rack of an oil tanker, including a large pipe rack base 6 and clamping plates 7. The two clamping plates 7 are symmetrically installed and respectively set on both sides of the large pipe rack base 6 to clamp and fix the large pipe rack base 6. The inner lining pad 8 is fixedly installed on the inner side of the clamping plate 7. It is made of a material with a high coefficient of friction, such as a rubber pad or an anti-slip pad, to increase the friction between the clamping plate 7 and the large pipe rack base material 6 and prevent relative sliding during clamping. The upper fixing tube 9 and the lower fixing tube 12 are fixedly installed on the diagonally opposite outer side of the clamping plate 7, and the two sets of upper fixing tubes 9 and lower fixing tubes 12 are installed in a staggered manner on the outer side of the two clamping plates 7. The middle of the upper fixing tube 9 and the lower fixing tube 12 on the same side is slidably inserted with a fixing pin 4, which is used to fix the two clamping plates 7 together.

[0017] In this embodiment, when the two clamping plates 7 are closed, the upper fixing tube 9 of the first clamping plate 7 is aligned with the lower fixing tube 12 of the second clamping plate 7, and the lower fixing tube 12 of the first clamping plate 7 is aligned with the upper fixing tube 9 of the second clamping plate 7. The fixing pin 4 is simultaneously slidably inserted into the aligned upper fixing tube 9 and lower fixing tube 12, thereby fixing the two clamping plates 7 together.

[0018] Furthermore, a transition slope 11 is provided on the top inner side of the lower fixed tube 12. The transition slope 11 makes the internal channel of the lower fixed tube 12 present a gradual structure from top to bottom, with the inner diameter of the lower half remaining unchanged.

[0019] In this embodiment, the design of the transition slope 11 facilitates the smooth insertion of the fixing pin 4 into the lower fixing tube 12 from above, serving as a guide.

[0020] Furthermore, a permanent magnet 10 is fixedly installed on the top of the upper fixing tube 9 to attract and fix the fixing pin 4.

[0021] In this embodiment, after the fixing pin 4 is inserted into the upper fixing tube 9 and the lower fixing tube 12, the permanent magnet 10 generates an adsorption force on the fixing pin 4, adsorbing and fixing the fixing pin 4 to prevent the fixing pin 4 from accidentally falling off due to vibration or other reasons during operation.

[0022] Furthermore, an adjusting rod 1 is fixedly connected to the outside of the clamping plate 7, and a main support frame 2 is slidably sleeved at the end of the adjusting rod 1. The main support frame 2 is a triangular frame structure welded from steel profiles, which has high structural strength and is used to bear the weight of the pipe.

[0023] Furthermore, the end of the adjusting rod 1 has a threaded hole, and the outer side of the main support frame 2 has multiple threaded holes. A locking bolt 5 is movably installed in the middle of the threaded holes of both.

[0024] In this embodiment, the locking bolt 5 passes through the threaded hole of the adjusting rod 1 and the threaded hole at the corresponding position on the main support frame 2, thereby achieving a fixed connection between the adjusting rod 1 and the main support frame 2. By sliding the adjusting rod 1 to different height positions and locking it with the locking bolt 5, the height of the clamping plate 7 can be adjusted, and the required position of the large pipe rack mother material 6 can be clamped, making it more widely applicable.

[0025] Furthermore, the bottom of the main support frame 2 is fixedly equipped with multiple casters 3, including at least three wheels arranged in a triangular pattern, and the casters 3 are equipped with independent brake pedals.

[0026] In this embodiment, the casters 3 allow the entire fixture to move flexibly, while the brake pedal can lock the wheels after the fixture is in place, preventing the fixture from moving accidentally during use.

[0027] Specific working methods: During the welding of the main pipe frame of VLCC and 114K large oil tanker, the two tooling fixtures are first pushed to the appropriate positions on both sides of the main pipe frame base material 6. According to the actual height of the main pipe frame base material 6, the adjusting rod 1 is slid along the main support frame 2, and then the locking bolt 5 is tightened to fix the height.

[0028] The two clamps 7 are closed from both sides, so that the inner lining 8 of the clamps 7 is in close contact with the surface of the main tube frame 6, and the main tube of the main tube frame 6 is wrapped inside. The fixing pins 4 are inserted into the upper fixing tube 9 and the lower fixing tube 12 from top to bottom. The permanent magnet 10 at the top of the upper fixing tube 9 attracts and fixes the fixing pins 4.

[0029] Depress the brake pedals of each caster wheel 3 to lock the tooling in position, and then proceed with welding and other operations.

[0030] After the welding operation is completed, pull out the fixing pin 4, loosen the two clamps 7, release the brake, and the tooling can be pushed away from the site, which is convenient and quick.

[0031] Example 2: The difference between this embodiment and Embodiment 1 is that the inner liner 8 is made of wear-resistant rubber material and is detachably fixed to the inside of the clamping plate 7 by bolts, so that it can be easily replaced when it wears out. The rest of the structure and usage are the same as in Embodiment 1.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
