Description

Technical Field

[0001] The utility model relates to the technical field of protection, in particular to a novel inflatable wire protection for a casing column. Background Art

[0002] After searching, the applicant found that a Chinese patent disclosed a "composite inflatable wire protector" with a publication (announcement) number of "CN210768640U". This patent mainly inflates the inflatable nozzle by inflating it through an external inflating device. When deflated, the air core is pressed to compress the spring, and the outlets on both sides of the air core are connected to the air in the air nozzle housing. At this time, the gas in the air nozzle housing leaks out along the T-shaped airway and the gap between the limit cover and the air core. However, the device can only be installed and protected for sleeves of the same size, resulting in low usability of the device. For this reason, we propose a new type of sleeve column inflatable wire protector. Utility Model Content

[0003] The utility model aims to provide a novel inflatable wire protection for a casing column.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of inflatable wire guard for casing column, comprising a support frame, a rubber air cover is fixedly connected to the side of the support frame, a limiting hole is provided on the inner wall of the support frame, a moving block is slidably connected in the limiting hole, a limiting plate is fixedly connected to the side of the moving block, an installation groove is provided on the side wall of the support frame, a spring is installed in the installation groove, and the end of the spring away from the installation groove is fixedly connected to the side of the limiting plate.

[0005] As a further solution of the utility model: an air storage cavity is formed between the support frame and the rubber air cover.

[0006] As a further solution of the utility model: a connecting pipe is fixedly connected to the upper end surface of the support frame, and the bottom end of the connecting pipe penetrates the inner wall of the support frame and is connected to the air storage cavity.

[0007] As a further solution of the utility model: the shape of the side surface of the moving block matches the shape of the limiting hole, and the number of the moving blocks matches the number of the limiting holes.

[0008] As a further solution of the utility model: the number of the springs matches the number of the installation slots, and the number of the limit plates matches the number of the moving blocks.

[0009] As a further solution of the utility model: the inner wall of the support frame and the side surface of the moving block are jointly provided with a protective rubber ring.

[0010] By adopting the above technical solution, compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The utility model inflates the air storage cavity through a connecting pipe. The air pressure will cause the rubber air hood to expand and open. At the same time, the air pressure will drive the moving block to move relatively through the limiting plate. The relative movement of the moving block can clamp and limit casing columns of various different sizes. After the limiting, the rubber air hood can protect the surface of the casing column, improving the practicability of the device.

[0012] 2. The utility model can drive the limiting plate to move away from each other through a spring, so that the moving block can contract in the limiting hole when the whole device is not working, avoiding the influence of the moving block protruding from the limiting hole on the next installation.

[0013] Other advantages, objectives and features of the utility model will be described to some extent in the subsequent specification, and to some extent, will be obvious to those skilled in the art based on the study of the following text, or can be taught from the practice of the utility model.

[0020] The following further describes the specific embodiments of the utility model with reference to the drawings. It should be noted here that the description of these embodiments is used to help understand the utility model, but does not constitute a limitation to the utility model.

[0021] In addition, the technical features involved in the various embodiments of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] Please refer to the attached Figure 1 - attached Figure 5, a novel inflatable thread protector for casing columns of the utility model, comprising a support frame 1, a rubber air hood 3 is fixedly connected to the side of the support frame 1, a limiting hole 7 is formed in the inner wall of the support frame 1, a moving block 4 is slidably connected in the limiting hole 7, a limiting plate 5 is fixedly connected to the side of the moving block 4, the size of the limiting block is larger than that of the limiting hole 7, and it can limit the moving block 4 when it moves, avoiding the moving block 4 from moving out of the limiting hole 7 completely. The shape of the side of the moving block 4 matches the shape of the limiting hole 7, and the number of the moving blocks 4 matches the number of the limiting holes 7. An installation groove 8 is formed in the side wall of the support frame 1, a spring 6 is installed in the installation groove 8, and the spring 6 can drive the moving block 4 to move away from each other through the limiting plate 5, so that the moving block 4 can be retracted into the limiting hole 7 when the air storage cavity is not inflated. The number of the springs 6 matches the number of the installation grooves 8, and the number of the limiting plates 5 matches the number of the moving blocks 4. One end of the spring 6 far away from the installation groove 8 is fixedly connected to the side of the limiting plate 5. A protective rubber ring is jointly arranged on the inner wall of the support frame 1 and the side of the moving block 4. The protective rubber ring can protect the casing column when the moving block 4 clamps the surface of the casing column, avoiding damage to the surface of the casing caused by clamping.

[0023] Embodiment 1, a gas storage cavity is formed between the support frame 1 and the rubber air hood 3. A connecting pipe 2 is fixedly connected to the upper end surface of the support frame 1, and the bottom end of the connecting pipe 2 penetrates through the inner wall of the support frame 1 and is communicated with the gas storage cavity;

[0024] Specifically, by connecting the connecting pipe 2 with an external inflation device, the gas storage cavity can be inflated, the rubber air hood 3 can be inflated, and the rubber air hood 3 can protect the clamped casing column. During the casing operation, external force damage to the thread can be avoided and deformation can occur, and the thread of the casing can be effectively protected.

[0025] Working principle:

[0026] First, the staff puts the whole device on the surface of the casing column, and then connects the connecting pipe 2 with an external inflation device to inflate the gas storage cavity. After inflation, the air pressure in the gas storage cavity increases, which can make the rubber air hood 3 expand. At the same time, the air pressure will squeeze the moving block 4 towards the center of the support frame 1 through the limiting plate 5, making the moving block 4 move out of the limiting hole 7. Moreover, when the limiting plate 5 moves, it will squeeze the spring 6 to make it contract. When the moving blocks 4 move relative to each other, they can clamp casing columns of various different sizes, and the rubber air hood 3 can protect them. When disassembling the whole device, inflation of the gas storage cavity can be stopped. At this time, under the action of the self-elastic force of the spring 6, the moving block 4 can be driven to move away from each other through the limiting plate 5, so that the moving block 4 is separated from the surface of the casing column, and the whole device can be removed from the casing column. Thus, the whole working process ends.
