Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to an end face protection device for pipe hoisting. Background Technology

[0002] During construction, pipes are usually buried in the ground and then transported to the designated location using hoisting equipment. During transportation, the pipe ends may collide or scratch with other objects, especially when placed. Therefore, pipe end face protection devices are used to protect the pipe ends.

[0003] In the prior art, pipe end face protection devices for pipe hoisting are generally clamps. By using clamps to hold the pipe end face, and utilizing the height difference between the clamps and the pipe end face, the friction between the pipe end face and the contact surface of the placement position is reduced, thereby achieving the effect of protecting the pipe end face.

[0004] However, in actual use, when the pipe end face is subjected to a severe impact during placement, the contact part between the clamp and the pipe end face will be impacted, resulting in deformation. Furthermore, once the contact part of the clamp on the pipe end face is offset, the pipe end face will be damaged due to the friction of the clamp. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a pipe end face protection device for pipe hoisting, so as to solve the problem that the protection of pipe end face by clamps in the prior art is relatively weak.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a pipe hoisting end face protection device, including a clamp one, a clamp two, and two placement slots. The two placement slots are respectively opened on the adjacent side of the clamp one and the clamp two. The top of the clamp one is fixedly connected to two guide rods, which are inserted into the interior of the clamp two. A rubber pad is detachably connected to the interior of the placement slot. The front and rear sides of the interior of the clamp two are provided with slots, and a locking block is locked inside the slot, and the locking block passes through the guide rod.

[0007] Among them, the inner walls of the two card slots are provided with mounting grooves on the adjacent side, and the adjacent side of the two card blocks are fixedly connected with connecting pieces. The other end of the connecting piece is fixedly connected with a pull rope, and an elastic element is sleeved on the outside of the pull rope.

[0008] The inner wall of the placement groove is fixedly connected to an elastic element two, the other end of which is detachably connected to a rubber pad. The inner wall of the placement groove is provided with a slot, a limit strip is slidably connected inside the slot, a rod is inserted inside the limit strip, and a connecting block is fixedly connected to the other end of the rod.

[0009] The pull rope is fixedly connected to a slider at the end away from the connecting piece, and extension blocks are fixedly connected to both sides of the slider. A groove is opened inside the top of the clamp two.

[0010] The connecting piece is slidably connected inside the mounting groove, and the pull rope is slidably connected inside the mounting groove.

[0011] One end of the elastic element is fixedly connected to the connecting piece, and the other end of the elastic element is fixedly connected to the inner wall of the mounting groove.

[0012] One of the insert rods is slidably connected inside the second clamp, and the other insert rod is slidably connected inside the first clamp. The upper side of the connecting block is inserted into the rear side of the second clamp, and the lower side of the connecting block is inserted into the right side of the first clamp.

[0013] The slider is slidably connected inside the groove, and the extension block is slidably connected to the groove inside the groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the above solution, a rubber pad is installed at the contact point between the clamp and the pipe end face to provide cushioning, and a locking block is used to limit the two clamps, thereby preventing the clamps from shifting at the pipe end face. This greatly reduces the possibility of the pipe end face being deformed due to impact and avoids damage to the pipe end face caused by clamp shifting, resulting in better protection of the pipe end face.

[0026] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0027] Example 1: Please refer to Figures 1 to 8 This utility model provides a technical solution: a pipe end-face protection device for pipe hoisting, including a clamp 1, a clamp 2, and two placement slots 4. The clamp 1 and clamp 2 together constitute the protection body, and multiple clamps 1 and multiple clamps 2 can be used on the pipe end face to disperse the tension at the protection point. The two placement slots 4 are respectively opened on the side close to the clamp 1 and clamp 2, so that the contact structure of clamp 2 and clamp 1 on the pipe end face is the same. Two guide rods 3 are fixedly connected to the top of clamp 1, and the two guide rods 3 are symmetrical. The distribution of force makes the clamp 1 more uniform. The guide rod 3 is inserted into the inside of the clamp 2, so that the clamp 1 and the clamp 2 can form a whole. The inside of the placement groove 4 is detachably connected with a rubber pad 5. The inside of the clamp 2 has a slot 6 on both the front and rear sides. The slot 6 is fitted with a locking block 7, and the locking block 7 passes through the guide rod 3, so that the guide rod 3 is limited. This makes the connection between the clamp 1 and the clamp 2 more stable, so that the clamp 1 and the clamp 2 are less likely to deviate at the pipe end face, and the protection effect is better.

[0028] When it is necessary to lift and protect the pipe end face, the edge of the pipe end face is placed between clamp 1 and clamp 2. Then, the guide rod 3 is slid into the interior of clamp 2, so that the two rubber pads 5 can respectively adhere to the wall of the pipe end face. Then, the two locking blocks 7 are moved to the opposite side, so that the locking blocks 7 can penetrate the guide rod 3 and engage with the interior of the locking groove 6. This limits clamp 1 and clamp 2, so that clamp 1 and clamp 2 have a good clamping effect on the pipe end face. Under the protection of the rubber pads 5, the possibility of the pipe end face being damaged by friction is greatly reduced, and the impact force on the pipe end face is buffered, so that the protective device can effectively protect the pipe end face.

[0029] Example 2: Based on Example 1, in order to facilitate the movement of the pull block 7, an installation groove 8 is provided on the adjacent side of the inner wall of the two slots 6. A connecting piece 9 is fixedly connected to the adjacent side of the two blocks 7. The connecting piece 9 is slidably connected inside the installation groove 8. The installation groove 8 limits the connecting piece 9, allowing the connecting piece 9 to slide smoothly. A pull rope 10 is fixedly connected to the other end of the connecting piece 9. The pull rope 10 is slidably connected inside the installation groove 8. The installation groove 8 limits the pull rope 10, preventing the pull rope 10 from deviating when sliding. An elastic element 11 is sleeved on the outside of the pull rope 10. One end of the elastic element 11 is fixedly connected to the connecting piece 9, and the other end of the elastic element 11 is fixedly connected to the inner wall of the installation groove 8.

[0030] When it is necessary to pull the locking block 7, by pulling the pull rope 10 to move away from the guide rod 3, the pull rope 10 can drive the connecting piece 9 to move away from the slot 6. This allows the connecting piece 9 to pull the locking block 7 away from the slot 6 and the inside of the guide rod 3 while compressing the elastic element 11 and causing it to deform. Conversely, by releasing the pull rope 10, the elastic element 11 can perform a reset movement, which in turn allows the elastic element 11 to push the connecting piece 9 to move closer to the slot 6. This allows the connecting piece 9 to push the locking block 7 through the guide rod 3 and engage with the inside of the slot 6.

[0031] Example 3: Based on Example 2, in order to improve the cushioning effect of the rubber pad 5 and increase the connection stability between clamp 1 and clamp 2, an elastic element 2 19 is fixedly connected to the inner wall of the placement groove 4. The other end of the elastic element 2 19 is detachably connected to the rubber pad 5, so that the rubber pad 5 can be separated from the elastic element 2 19. A slot 14 is provided on the inner wall of the placement groove 4. A limit strip 12 is slidably connected inside the slot 14. The slot 14 provides installation space for the limit strip 12. The bottom end of the limit strip 12 is connected to one of the elastic elements 2 19, so that the elastic element 2 19 can be separated from the rubber pad 5. When deformation occurs, the limiting strip 12 is pushed to slide. A rod 13 is inserted inside the limiting strip 12. One rod 13 is slidably connected inside the second clamp 2, and the other rod 13 is slidably connected inside the first clamp 1, so that the rod 13 can slide smoothly. The other end of the rod 13 is fixedly connected to a connecting block 15. The upper side of the connecting block 15 is inserted into the rear side of the second clamp 2, and the lower side of the connecting block 15 is inserted into the right side of the first clamp 1. The connecting block 15 is used to limit the first clamp 1 and the second clamp 2 for a second time, so that the first clamp 1 and the second clamp 2 will not shift.

[0032] When the rubber pad 5 needs to be installed inside the placement slot 4, the rubber pad 5 can compress the elastic element 2 19 to deform, thereby allowing one of the elastic elements 2 19 to push the limiting strip 12 to slide inside the slot 14. After the rubber pad 5 is installed, by inserting the plug 13 on the connecting block 15 into the limiting strip 12, and making the connecting block 15 inserted into the right side of clamp 1 and clamp 2, clamp 1 and clamp 2 can be limited, and the installation stability of the rubber pad 5 is high.

[0033] Example 4: Based on Example 3, in order to facilitate the pulling of the pull rope 10, a slider 16 is fixedly connected to the end of the pull rope 10 away from the connecting piece 9. The slider 16 is used to pull the pull rope 10 to move. Extension blocks 17 are fixedly connected to both the left and right sides of the slider 16. A groove 18 is opened inside the top of the clamp 2. The slider 16 is slidably connected inside the groove 18. The extension block 17 is slidably connected to the groove inside the groove 18. The groove 18 and the extension block 17 limit the slider 16, so that the slider 16 will not detach from the inside of the groove 18 when moving. Under the action of the extension block 17, by pulling the slider 16 upward, the clamp 2 can be moved upward.

[0034] When it is necessary to pull the rope 10, the two sliders 16 are pulled to the same side, which in turn drives the rope 10 to move.

[0035] The working process of this utility model is as follows:

[0036] When clamp 1 and clamp 2 need to be installed on the pipe end face, first place the rubber pad 5 inside the placement groove 4, and then fit clamp 1 against the pipe end face. Next, by engaging the two sliders 16, the sliders 16 pull the pull rope 10 away from the guide rod 3, causing the pull rope 10 to cause the connecting piece 9 to deform by squeezing the elastic element 11. This causes clamp 2 to slide downwards outside the guide rod 3, allowing the lower side of clamp 2 to fit against the pipe end face. At this time, the rubber pad 5 squeezes the elastic element 19, causing it to deform, thus pushing one of the elastic elements 19 to the limit position. When the strip 12 slides inside the slot 14, the elastic element 11 is reset by releasing the slider 16, which in turn pushes the connecting piece 9 towards the slot 6. This allows the connecting piece 9 to push the locking block 7 through the guide rod 3 and engage with the slot 6, connecting clamp 1 and clamp 2. Then, by inserting the rod 13 on the connecting block 15 into the limiting strip 12 and inserting the connecting block 15 into the right side of clamp 1 and clamp 2, clamp 1 and clamp 2 are limited, and the installation stability of the rubber pad 5 is high.
