Description

Technical Field

[0001] This utility model relates to a pipeline sealing device, specifically a clamping and sealing device for evacuating a pipeline. Background Technology

[0002] Pipeline vacuuming is a crucial step in pipeline transportation, applied in various fields such as industry, laboratory, and food processing. Examples include production pipelines in the petroleum and chemical industries, and pipelines in food processing and pharmaceutical industries. Gases within pipelines can have varying degrees of impact on the production process, causing resistance, interference, and blockages. Pipeline vacuuming can address these issues. Pipeline vacuuming helps improve production efficiency, reduce material waste, and ensure the quality and hygiene standards of the produced products.

[0003] Current pipeline vacuuming involves connecting a vacuum pump to the pipeline to be vacuumed. The pipeline to be vacuumed and the vacuum pump need to be clamped and sealed. The clamping and sealing device needs to be fixed to the pipeline to be vacuumed by components such as clamping rings and screws. All of these can only be installed and fixed manually, which is inefficient and the clamping and sealing effect is unstable. Utility Model Content

[0004] This utility model provides a clamping wooden block device for heat pipe vacuuming, which is used to improve the efficiency and effect of clamping and sealing when connecting a vacuum pump.

[0005] A clamping and sealing device for evacuating a pipeline includes a first support frame and a sealing block. One end of the sealing block is connected to a vacuum pump, and the other end is connected to the pipeline to be evacuated. A cylinder is mounted on the first support frame, and a dragging block is connected to the output end of the cylinder. The sealing block is connected to the dragging block and is located at the front end of the first support frame. A second support frame is connected to the rear end of the first support frame. A left clamping claw and a right clamping claw are respectively hinged to the left and right ends of the second support frame. The left and right clamping claws are used to clamp the pipeline to be evacuated. The left and right clamping claws are connected by a first tension spring, so that the left and right clamping claws clamp the pipeline to be evacuated without external force.

[0006] The middle parts of the left and right clamping claws are respectively hinged to the left and right ends of the second support frame. The lower inner sides of the left and right clamping claws are provided with arc-shaped surfaces, which clamp the pipe to be vacuumed. When the left and right clamping claws clamp the pipe to be vacuumed, there is a gap between the upper end of the left clamping claw and the upper end of the right clamping claw.

[0007] The cylinder is a dual-axis cylinder, with a first output shaft and a second output shaft respectively provided at the front and rear ends of the dual-axis cylinder. The first output shaft is connected to the drag block; a locking block is installed on the second output shaft, and the locking block is located in the gap between the upper end of the left clamping jaw and the upper end of the right clamping jaw.

[0008] Furthermore, the first support frame is provided with strip grooves on both sides, and the sealing and pressing block is provided with connecting columns on both sides, with the connecting columns passing through the strip grooves; it also includes a second tension spring, with hooks provided at both ends of the second tension spring, with one hook of the second tension spring hanging on the connecting column and the other hook of the second tension spring hanging on the dragging block.

[0009] Furthermore, the sealing and clamping block is used to clamp a soft rubber inside one side of the pipe to be vacuumed.

[0010] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0011] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0012] The clamping assembly consisting of a left and right clamping claw replaces the traditional screw fixing method. Utilizing the elasticity of the first tension spring, the left and right clamping claws quickly clamp the pipe to be vacuumed, thus achieving rapid fixation of the pipe. The sealing assembly consisting of a cylinder and a sealing pressure block has a faster response speed during the sealing process. Furthermore, the cylinder provides the driving force to press the sealing pressure block firmly against the port of the pipe to be vacuumed, resulting in a strong seal and reducing the likelihood of leakage.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.

[0020] like Figure 1 , Figure 2 As shown, a clamping and sealing device for evacuating a pipeline includes a first support frame 2 and a sealing and pressing block 7. One end of the sealing and pressing block 7 is connected to a vacuum pump, and the other end is connected to the pipeline 1 to be evacuated. A cylinder is installed on the first support frame 2, and a dragging block 6 is connected to the output end of the cylinder. The sealing and pressing block 7 is connected to the dragging block 6 and is located at the front end of the first support frame 2. A second support frame 8 is connected to the rear end of the first support frame 2. A left clamping claw 9 and a right clamping claw 10 are respectively hinged to the left and right ends of the second support frame 8. The left clamping claw 9 and the right clamping claw 10 are used to clamp the pipeline 1 to be evacuated. The left clamping claw 9 and the right clamping claw 10 are connected by a first tension spring, so that the left clamping claw 9 and the right clamping claw 10 clamp the pipeline 1 to be evacuated without external force.

[0021] The improvement of this utility model lies in the fact that the clamping assembly composed of the left clamping claw 9 and the right clamping claw 10 replaces the screw fixing method in the traditional fixing method. The elastic force of the first tension spring allows the left clamping claw 9 and the right clamping claw 10 to quickly clamp the vacuum-to-be-vacuumed pipe 1, thus completing the rapid fixing of the vacuum-to-be-vacuumed pipe 1. The sealing assembly composed of the cylinder and the sealing pressure block 7 has a faster response speed during the sealing process, and the cylinder provides the driving force to press the sealing pressure block 7 against the port of the vacuum-to-be-vacuumed pipe 1, resulting in a strong seal and reducing the likelihood of leakage.

[0022] like Figure 3 , Figure 4 As shown, furthermore, the middle portions of the left clamping claw 9 and the right clamping claw 10 are respectively hinged to the left and right ends of the second support frame 8. The lower inner sides of both the left clamping claw 9 and the right clamping claw 10 are provided with arc-shaped surfaces, which clamp the vacuum-to-be-vacuumed pipe 1. When the left clamping claw 9 and the right clamping claw 10 clamp the vacuum-to-be-vacuumed pipe 1, there is a gap between the upper end of the left clamping claw 9 and the upper end of the right clamping claw 10. The process of the sealing and pressing block 7 pressing the port of the vacuum-to-be-vacuumed pipe 1 is not simply compression; the sealing and pressing block 7 also has a channel communicating with the vacuum pump. Therefore, there is a problem that the port of the vacuum-to-be-vacuumed pipe 1 and the internal channel of the sealing and pressing block 7 need to be aligned during the pressing process. The lower inner sides of the left clamping claw 9 and the right clamping claw 10 are both provided with arc-shaped surfaces. Under the elastic force of the first tension spring, the left clamping claw 9 and the right clamping claw 10 clamp the vacuum pipe 1 to be evacuated. Due to the arc-shaped surfaces, the left clamping claw 9 and the right clamping claw 10 can only be clamped at the arc-shaped surface position after clamping, so that the port of the vacuum pipe 1 to be evacuated is automatically aligned with the internal channel of the sealing and pressing block 7.

[0023] Preferably, the cylinder is a dual-axis cylinder 3, with a first output shaft 4 and a second output shaft 5 respectively provided at the front and rear ends of the dual-axis cylinder 3. The first output shaft 4 is connected to the drag block 6. A locking block 11 is installed on the second output shaft 5, and the locking block 11 is located in the gap between the upper end of the left clamping claw 9 and the upper end of the right clamping claw 10. The first output shaft 4 of the dual-axis cylinder 3 is connected to the drag block 6. Controlling the extension and retraction of the first output shaft 4 can seal or loosen the sealing and clamping block 7 at the port of the vacuum pipe 1 to be evacuated. The second output shaft 5 of the dual-axis cylinder 3 is connected to the locking block 11. When the left clamping claw 9 and the right clamping claw 10 have finished clamping, the locking block 11 is locked in the gap between the upper end of the left clamping claw 9 and the upper end of the right clamping claw 10 under the outward push of the second output shaft 5. This obstructs the stroke of the left clamping claw 9 and the right clamping claw 10 to release the vacuum pipe 1 to be evacuated. Therefore, the left clamping claw 9 and the right clamping claw 10 are in a locked state and cannot be released under external force.

[0024] like Figure 5 As shown, furthermore, the first support frame 2 has strip grooves on both sides, and the sealing and pressing block 7 has connecting posts on both sides, which pass through the strip grooves; it also includes a second tension spring, with hooks at both ends. One hook of the second tension spring hangs on the connecting post, and the other hook hangs on the drag block 6. The drag block 6 and the sealing and pressing block 7 are connected by the second tension spring, which is used to solve the problem of excessive compression between the sealing and pressing block 7 and the port of the vacuum pipe 1 caused by a large extension and retraction of the first output shaft 4. The second tension spring can balance the extension and retraction of the first output shaft 4 and avoid damage to the vacuum pipe 1 caused by excessive compression.

[0025] Furthermore, the sealing and clamping block 7 is used to clamp the side of the vacuum pipe 1 to be vacuumed, which is provided with soft rubber to avoid air leakage caused by the gap between the sealing and clamping block 7 and the vacuum pipe 1.
