Description

TECHNICAL FIELD

[0001] The utility model relates to tank body clamping technical field, especially a tank body clamping device for chemical processing. BACKGROUND

[0002] In the current chemical processing industry, the tank body clamping device for chemical processing is of great significance to ensure production stability and safety. However, the existing technology has many deficiencies, which seriously restricts the development of the industry.

[0003] From the perspective of mechanical structure, traditional clamping devices mostly rely on simple mechanical structures, such as bolt fastening, clamp clamping, etc. These structures have poor flexibility and are difficult to achieve uniform clamping of the tank body. For large tank bodies, it is difficult to achieve uniform force due to the length of the mechanical arm and the opening and closing range of the clamp, resulting in excessive clamping force in some areas and insufficient clamping in some areas. For special-shaped tank bodies, the traditional structure is difficult to fit their complex shape, causing the clamping force to concentrate on a few contact points, with local stress far exceeding the tank body's bearing range. Especially when facing thin-walled or soft tank bodies, the problem is more prominent. Local excessive clamping force can easily cause the tank body to deform, not only affecting the appearance of the tank body, but also reducing its structural strength. The sealing performance of the tank body will also decrease due to deformation, leading to chemical leakage, which not only causes material loss, but also may cause safety accidents such as fire, explosion, and poisoning, posing a serious threat to personnel safety and the environment. In view of this, a tank body clamping device for chemical processing is proposed. SUMMARY

[0004] The main purpose of the utility model is to provide a tank body clamping device for chemical processing, which can effectively solve the problems in the background art.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1-5 As shown, a tank clamping device for chemical processing includes a connecting plate 1 and two explosion-proof boxes 2 arranged symmetrically. In the overall application scenario, one side of the connecting plate 1 is connected to the end of a transport robot in the prior art. The transport robot works with this tank clamping device for chemical processing to realize the automated transport of the tank for chemical processing.

[0026] refer to Figure 1 and Figure 3As shown, on the mechanical structure connection, the two sides of the explosion-proof box 2 are synchronously and reversely moved and installed on one side of the connecting plate 1. In order to realize this movement, two opposite air cylinders 7 are fixedly installed on the same side of the connecting plate 1. The ends of the piston rods of the air cylinders 7 are fixedly connected with the two explosion-proof boxes 2, respectively. When the air cylinders 7 work, the piston rods thereof are extended and retracted, and the explosion-proof boxes 2 are synchronously and reversely moved on the connecting plate 1, thereby meeting the clamping requirements of tank bodies of different sizes.

[0027] Reference Figure 3 and Figure 4 As shown, into the explosion-proof box 2, a plurality of cylinder barrels 5 are fixedly installed in the explosion-proof box 2 in a matrix shape. An active push rod 3 is telescopically installed in each cylinder barrel 5. The front end of the active push rod 3 is installed in the cylinder barrel 5 in a piston sealing manner. This sealing manner can ensure that the air pressure in the cylinder barrel 5 is stable, and effectively push the active push rod 3 to extend and retract. Meanwhile, a partition plate 4 is fixedly installed in the explosion-proof box 2. The partition plate 4 is fixedly connected with the front end of the cylinder barrel 5. The partition plate 4 is provided with a plurality of circular holes 8 which are in communication with the inner cavities of the front ends of the cylinder barrels 5. The inner diameters of the circular holes 8 are smaller than the inner diameters of the cylinder barrels 5. This structure further stabilizes the air pressure in the cylinder barrel 5, and guarantees that the active push rod 3 extends and retracts stably.

[0028] It should be noted that, in terms of gas control, one side of the explosion-proof box 2 is fixedly connected with a gas nozzle 6. One end of the gas nozzle 6 is connected with a two-position three-way electromagnetic valve. Specifically, the common port of the two-position three-way electromagnetic valve is fixedly connected with the gas nozzle 6. The normally open port is connected with a negative pressure air suction source, and the normally closed port is connected with a high-pressure air charging source. In this embodiment, the high-pressure air charging source is selected to be a high-pressure tank or a compressor, and the negative pressure air suction source is selected to be a vacuum pump. When it is needed to clamp a tank body, the two-position three-way electromagnetic valve is switched, so that the normally closed port is connected with the common port. The high-pressure air charging source charges high-pressure gas into the explosion-proof box 2, and pushes the active push rod 3 to extend. When it is needed to release the tank body, the two-position three-way electromagnetic valve is switched, so that the normally open port is connected with the common port. The negative pressure air suction source extracts the gas in the explosion-proof box 2, and makes the active push rod 3 retract.

[0029] Reference Figure 4 As shown, in order to protect the clamped tank body, the end of the active push rod 3 is provided with a gasket 10. The back surface of the gasket 10 is fixedly connected with a ball 11 which is rotatably installed at the end of the active push rod 3. When the gasket 10 contacts with the tank body, it can rotate flexibly, and reduces the damage to the surface of the tank body. The front end of the active push rod 3 is fixedly connected with a buffer pad 9. The outer diameter of the buffer pad 9 is larger than the inner diameter of the circular hole 8, and plays a buffering and sealing role. In addition, the outer side end surface of the gasket 10 is fixedly connected with a rubber pad 12, which further enhances the friction force and protection effect when contacting with the tank body, and guarantees the stability of the tank body in the clamping process.

[0030] In actual operation, when the chemical processing tank needs to be clamped, first start the control system in the handling robot, control the two-position three-way electromagnetic valve to switch to the state of communicating the normally closed port with the common port, at this time, the high-pressure gas source starts to work, and high-pressure gas is filled into the explosion-proof box 2, after the high-pressure gas enters the explosion-proof box 2, it acts uniformly in each cylinder 5, and pushes the movable push rod 3 to extend, because all movable push rods 3 are pushed by the same pressure of high-pressure gas, they are synchronized to extend and contact the outer wall of the tank, and the extension and contraction degree is automatically adjusted according to the shape and size of the tank outer wall, so that the clamping is tight and uniform;

[0031] When the tank needs to be released, the two-position three-way electromagnetic valve is switched to the state of communicating the normally open port with the common port, the negative pressure gas source is started, the gas in the explosion-proof box 2 is extracted, and a negative pressure environment is formed in the explosion-proof box 2, under the action of negative pressure, the movable push rod 3 is retracted, so that the clamping of the tank is released, the whole operation process is realized through the automatic control system, the operation is simple and fast, and the timing and force of clamping and releasing can be accurately controlled.

[0032] In addition, in order to ensure the stable operation of the device and the accuracy of gas control, a pressure sensor is arranged in the explosion-proof box 2, the gas pressure in the box is monitored in real time, and the data is fed back to the control system, the control system controls the two-position three-way electromagnetic valve, the high-pressure gas source and the negative pressure gas source according to the preset pressure range and operation process, so as to ensure the safety and reliability of the whole clamping process.
