Description

Technical Field

[0001] This utility model relates to chemical machinery and equipment, specifically to leak detection of chemical machinery and equipment. Background Technology

[0002] Chemical machinery is a general term for machines and equipment used in chemical industrial production. In chemical production, raw materials are processed into finished products of specific specifications. However, over time, aging and leaks can easily occur at the connections of chemical equipment, necessitating specialized equipment for detection. Currently, leak detection equipment is typically installed at the release point, pipe connections, and flange connections. These devices are usually bolted to the conveying pipelines of the chemical machinery. Because the rear surface of the detection equipment is flat, the contact between the rear surface of the equipment and the side surface of the pipeline is linear, leading to instability and causing the equipment to rotate on the pipeline after installation. Utility Model Content

[0003] The technical problem solved by this utility model is that the existing testing equipment is installed on the conveying pipeline of chemical machinery by bolts. After installation, the rear surface of the testing equipment is in linear contact with the side surface of the pipeline, which leads to unstable installation of the testing equipment and the testing equipment will rotate on the pipeline after installation.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a leak detection device for chemical machinery, including a main platform, grippers connected to the main platform, and a detection device body installed on the main platform. The main platform is connected to at least one pair of grippers, any gripper is arc-shaped, any pair of grippers are arranged opposite each other, a gripper connection hole is opened at the free end of any gripper, a gripper fastening bolt is fitted in the gripper connection hole of any pair of grippers, a cylindrical slider is provided at the connecting end of any gripper, a circular hole structure is opened on the side of the main platform, and the grippers are connected to the main platform through the sliding cooperation of the cylindrical slider and the circular hole structure.

[0005] The cylindrical slider of the gripper located on the left side of the conveying pipe first mates with the circular hole structure on the left side of the main platform. Then, along the axial direction of the conveying pipe, the cylindrical slider of the gripper on the right side of the conveying pipe mates with the circular hole structure on the right side of the main platform, aligning the gripper on the right side of the conveying pipe with the gripper on the left side. Finally, the gripper fastening bolts connect the grippers on both sides of the conveying pipe, bringing the grippers on both sides closer together and clamping them onto the conveying pipe.

[0006] The arc-shaped gripper of this invention makes surface contact with the surface of the conveying pipe, which can increase the friction between the gripper and the conveying pipe, prevent the testing equipment from rotating on the conveying pipe after installation, and thus improve the installation stability of the testing equipment.

[0007] The cylindrical slider and the gripper body are connected by a slider connection part, and the circular hole structure has a notch, which is matched with the slider connection part.

[0008] Each gripper has an auxiliary gripper hole, in which an auxiliary fastening bolt is screwed. One end of the auxiliary fastening bolt can be radially opposed to the conveying pipeline, improving the stability of the testing equipment on the conveying pipeline.

[0009] The main platform is equipped with a disc-shaped platform, which has a disc-shaped positioning groove. A connecting plate fits into the disc-shaped positioning groove, and radial fastening screws are screwed onto the side wall of the disc-shaped platform. The connecting plate is fixedly connected to the main body of the detection equipment. The connecting plate can rotate relative to the disc-shaped platform, and consequently, the main body of the detection equipment can rotate relative to the main platform. This allows the gas detection end of the main body of the detection equipment to be closer to the gas leak release source, thus avoiding delayed alarms and reducing installation hazards. After the position of the main body of the detection equipment is adjusted, the radial fastening screws are tightened to fix the position of the main body of the detection equipment.

[0010] The disc-shaped platform is fixedly connected to the main platform by a number of platform connecting bolts. All platform connecting bolts are located in the disc-shaped positioning groove and are distributed on the same circle. The center of the circle coincides with the center of the disc-shaped positioning groove. The bottom of the connecting disc is provided with a circular positioning groove. All platform connecting bolts are located in the circular positioning groove, and the outer side wall of the bolt head of all platform connecting bolts abuts against the inner side wall of the circular positioning groove.

[0011] The outer wall of the connecting plate abuts against the inner wall of the disc-shaped positioning groove, and the inner wall of the circular positioning groove abuts against the outer wall of the bolt head of all the platform connecting bolts. In this way, when the radial fastening screw applies radial force to the connecting plate, the connecting plate can be stably connected to the disc-shaped platform.

[0012] The connecting plate is connected to the main body of the testing equipment by a concealed connecting bolt, the bolt head of which is located in the circular positioning groove. Attached Figure Description
