Description

Technical Field

[0001] The utility model relates to a protection device for titanium alloy pipes, in particular to a protection device for the ends of titanium alloy pipes. Background Art

[0002] In order to avoid mechanical damage to titanium alloy pipes during transportation, which may affect their performance, it is often necessary to provide certain protection for the ends of titanium alloy pipes. Especially when lifting titanium alloy pipes, the hooks are usually connected to both ends of the titanium alloy pipes, which easily causes damage to the surface of the titanium alloy pipes.

[0003] In the prior art, protective caps are usually designed for the ends of titanium alloy pipes to prevent their ends from being collided or damaged during transportation. However, this will cause the lifting parts to be unable to be connected to the ends of the titanium alloy pipes. As a result, the sling can only be connected to the middle position of the titanium alloy pipe. This is not only troublesome but also relatively less stable. Summary of the Utility Model

[0004] To solve the above problems, the utility model provides a protection device for the ends of titanium alloy pipes that is not easy to fall off and is convenient for transporting titanium alloy pipes.

[0005] To achieve the above object, the technical solution of the utility model is: a protection device for the ends of titanium alloy pipes, including protective caps installed at both ends of the titanium alloy pipe. A flat through-hole is provided on the protective cap. A flat cross-strap is connected between the two protective caps, and the cross-strap can pass through the flat through-hole.

[0006] The protective cap includes a sleeve and a cover. The cover is fixed at one end of the sleeve. The sleeve can be sleeved on the end of the titanium alloy pipe. The flat through-hole is located at the center of the cover.

[0009] The cross-strap includes a flat belt body. A perforated section is provided on the belt body. The perforated section is located at the end of the belt body.

[0010] Furthermore, two grooves are provided on the outer side surface of the cover. The two grooves are respectively located above and below the flat through-hole. A through-hole is provided in the groove and a flipping strip plate is hinged in the groove.

[0011] Further, a pushing plate is arranged on the turning and pressing strip plate. When the turning and pressing strip plate enters the groove, the pushing plate passes through the through port, and the pushing plate applies a thrust to the end of the clamping plate.

[0012] Further, an elastic pressing assembly is connected to the protruding rib plate. The elastic pressing assembly includes a telescopic rod. A sleeve is sleeved on the telescopic rod. The sleeve is fixed on the protruding rib plate, and the telescopic rod is connected to the clamping plate.

[0013] Further, the telescopic rod includes a straight pipe and a straight rod.

[0015] Further, locking covers located on both sides of the groove are arranged on the cover. A locking rod is pivotally connected to the turning and pressing strip plate, and the locking rod can rotate.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows: The device includes protective caps installed at both ends of the titanium alloy pipe. A cross-strap is connected between the two protective caps. The end of the cross-strap passes through the protective cap, and the cross-strap is connected to the protective cap through a locking clip assembly, so that the connection between the protective cap and the titanium alloy pipe can be made more stable;

[0017] Perforated segments are arranged on the cross-strap. During transportation, the iron wire can pass through the perforations on several cross-straps, and then the two ends of the iron wire are screwed and butted, so as to avoid the titanium alloy pipe from scattering during transportation. When a single titanium alloy pipe is hoisted, the hook can also be hung at the perforated segment of the cross-strap;

[0018] A marking sleeve or a marking cap can be sleeved at the end of the cross-strap. When it is necessary to check the quantity of titanium pipes transported in batches, the marking sleeve or the marking cap on each cross-strap can be removed, and by checking the quantity of the marking sleeve or the marking cap, the quantity of the titanium alloy pipes can be known, which is relatively convenient.

[0031] Refer to Figure 1 and Figure 2 As shown, a titanium alloy pipe end protection device includes protective caps 1 installed at both ends of the titanium alloy pipe 27. A flat cross strap 2 is connected between the two protective caps 1. A locking clip assembly is provided on the protective cap 1, and the locking clip assembly is connected to the cross strap 2. After both protective caps 1 are installed at both ends of the titanium alloy pipe 27, the cross strap 2 can be straightened, and at this time, the protective cap 1 is not easily separated from the titanium alloy pipe 27.

[0032] Refer to Figure 3 and Figure 4 As shown, the protective cap 1 includes a sleeve 3 and a cover 4. The cover 4 is fixed to one end of the sleeve 3. The above-mentioned locking clip assembly is fixed on the cover 4. The sleeve 3 can be sleeved on the end of the titanium alloy pipe 27. A flat through hole 5 is provided at the center position of the cover 4, and the cross strap 2 can pass through the flat through hole 5.

[0033] Refer to Figure 1 and Figure 5 As shown, the cross strap 2 includes a flat belt body 6. A perforated section is provided on the belt body 6, and the perforated section is located at the end of the belt body 6. Specifically, a number of through holes 7 are provided at the end of the cross strap. The number of through holes 7 are arranged at equal intervals along the length direction of the cross strap 2. A metal ring is inlaid in each through hole 7. After the cross strap 2 passes through the flat through hole 5, the perforated section is located outside the protective cap 1.

[0034] Refer to Figure 3 and Figure 6As shown in the figure, the above-mentioned lock clip assembly includes two clamping plates 8, which are respectively located above and below the flat opening. At this time, the two clamping plates 8 are located inside the sleeve 3. One end of the clamping plate 8 is provided with a long strip notch 9, and the long strip notch 9 extends along the length direction of the clamping plate 8. On the inner side of the cover 4, there is a protruding rib plate 10, and the protruding rib plate 10 is located at the long strip notch 9. The clamping plate 8 is pivotally connected to the protruding rib plate 10, and the clamping plate 8 can be flipped with the pivot point as the base point. When the end of the clamping plate 8 close to the cover 4 is subjected to a pushing force, the end of the clamping plate 8 close to the cover 4 can be flipped away from the horizontal pulling belt 2, and at this time, the other end of the clamping plate 8 is flipped in the opposite direction. When the two clamping plates 8 move simultaneously, the clamping of the horizontal pulling belt 2 can be achieved. In addition, an arc-shaped notch 11 is provided on the protruding rib plate 10, and the pivot point of the clamping plate 8 and the protruding rib plate 10 is the center of the arc of the arc-shaped notch 11. A pull rod 12 is arranged in the long strip notch 9 of the clamping plate 8, and the pull rod 12 passes through the arc-shaped notch 11, thus ensuring the force-bearing strength of the clamping plate 8.

[0035] Refer to Figure 4 and Figure 7 As shown in the figure, on the outer side surface of the cover 4, there are two long strip-shaped grooves 13, and the two grooves 13 are respectively located above and below the flat through-hole 5. At the end of the groove 13 far from the flat through-hole 5, there are two first through-holes 14. A turning and pressing strip plate 15 is hinged in the groove 13. One end of the turning and pressing strip plate 15 is hinged to the end of the groove 13 close to the flat through-hole 5. Two pushing plates 16 are fixed at the upper end of the turning and pressing strip plate 15. When the turning and pressing strip plate 15 is flipped so that the upper end of the turning and pressing strip plate 15 enters the groove 13, the two pushing plates 16 pass through the corresponding first through-holes 14 (after the pushing plates 16 pass through the first through-holes 14, the protruding rib plate 10 is located between the two pushing plates 16). The side edge of the pushing plate 16 in contact with the clamping plate 8 is an arc-shaped edge. During this process, both of the two pushing plates 16 apply a thrust to the end of the clamping plate 8, thereby promoting the flipping of the clamping plate 8 and realizing the clamping of the horizontal pulling belt 2.

[0036] Refer to Figure 8As shown, in order to enable the clamping plate 8 to apply a continuous clamping force to the horizontal pulling belt 2, an elastic pressing assembly 17 is connected to the clamping plate 8. There are two elastic pressing assemblies 17 on each clamping plate 8, and the two pressing assemblies are symmetrically distributed on both sides of the strip-shaped notch. Moreover, the elastic pressing assembly 17 is simultaneously connected to the protruding rib plate 10. The elastic pressing assembly 17 includes a telescopic rod, and a sleeve 18 is sleeved on the telescopic rod. The sleeve 18 is fixedly connected to the protruding rib plate 10. The telescopic rod includes a straight pipe 19 and a straight rod 20. The above-mentioned sleeve 18 is sleeved on the straight pipe 19, and the outer diameter of the straight rod is adapted to the inner diameter of the straight pipe 19, and the straight rod can be inserted into the straight pipe 19. A compression return spring 21 is arranged in the straight pipe 19, and both ends of the compression return spring 21 are respectively connected to the inner wall of the sleeve 3 and the straight rod 20. The other end of the straight rod 20 is connected to the clamping plate 8. The specific connection structure between the straight rod 20 and the clamping plate 8 is as follows:

[0037] Two protruding rods 22 are arranged at the end of the straight rod 20, and the two protruding rods 22 are symmetrically distributed. Two waist-shaped openings 23 are arranged on the clamping plate 8, and sliding grooves 24 are arranged on two opposite side vertical surfaces of the waist-shaped opening 23. The sliding grooves 24 extend along the length direction of the waist-shaped opening 23, and the protruding columns on the straight rod 20 are adapted to be in the sliding grooves 24; before the pushing plate 16 passes through the first through hole 14, the compression return spring 21 is in a natural state. At this time, there is a certain gap between the two clamping plates 8, and the horizontal pulling belt 2 can pass through this gap. When the pushing plate 16 passes through the first through hole 14, it causes the two clamping plates 8 to flip, and the two clamping plates 8 can clamp the horizontal pulling belt 2. At the same time, the clamping plate 8 applies a thrust to the telescopic rod on the elastic pressing assembly 17 at the corresponding position, and the end of the straight pipe 19 on the telescopic rod abuts against the inner wall of the titanium pipe. As the clamping plate 18 continues to flip, the compression return spring 21 becomes a compressed state, so that the connection stability between the protective cap 1 and the titanium alloy pipe 27 can be increased.

[0038] Refer to Figure 4 As shown, locking covers 25 are arranged on the cover 4 on both sides of the groove 13. The locking covers 25 are fixed to the cover 4, and at this time, an interval space is formed between the locking covers 25 and the cover 4. A locking rod 26 is pivotally connected to the end of the turning and pressing strip 15 away from the flat opening. The locking rod 26 can rotate. When the turning and pressing strip 15 is completely fitted in the groove 13, the locking rod 26 can be rotated so that the end of the locking rod 26 enters the interval space.

[0039] When several titanium alloy tubes 27 are transported centrally, the iron wire can be passed through the perforations on several horizontal pulling belts 2, and then the two ends of the iron wire are butted by screwing. In this way, the titanium alloy tubes 27 can be prevented from scattering during transportation. When it is necessary to carry a certain titanium alloy tube 27, the acting force can be applied to the perforated section of the horizontal pulling belt 2 to avoid direct contact with the titanium alloy tube 27. Because if the wall thickness of the titanium alloy tube 27 is small, if the acting force is directly applied, it is easy to cause local deformation of the titanium alloy tube 27.

[0040] In addition, a marking sleeve or a marking cap can be sleeved at the end of the horizontal pulling belt 2. When it is necessary to check the quantity of the titanium tubes transported in batches, the marking sleeves or marking caps on each horizontal pulling belt 2 can be removed. By checking the quantity of the marking sleeves or marking caps, the quantity of the titanium alloy tubes 27 can be known, which is relatively convenient.

[0041] When using the above-mentioned titanium alloy tube end protection device, first pass the horizontal pulling belt 2 through the inside of the titanium alloy tube 27, and then turn the pressing strip 15 into the groove 13 on the cover 4. The pushing plate 16 on the pressing strip 15 applies a thrust to the end of the clamping plate 8, so as to promote the clamping plate 8 to turn and realize the clamping of the horizontal pulling belt 2. At the same time, the straight pipe 19 of the elastic pressing assembly 17 on the clamping plate 8 abuts against the inner wall of the titanium alloy tube 27. Then rotate the locking rod 26 so that the end of the locking rod 26 enters the spaced space, thereby locking the position of the clamping plate 8 and enhancing the connection stability between the protective cap 1 and the titanium alloy tube 27.

[0042] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claimed rights.
