Description

Technical Field

[0001] The utility model relates to the technical field of ton tank production, and more specifically, to a clamping device for ton tank production. Background Art

[0002] A ton tank, also known as a container barrel or ton barrel, is a supporting container widely used in liquid packaging, warehousing, and transportation, with good acid and alkali corrosion resistance. During the production process of ton tanks, a clamping device for ton tank production is required to stably clamp and support the ton tank during processing, transportation, installation, etc.

[0003] The existing devices still have the following deficiencies: (1) The existing devices usually use hydraulic or pneumatic methods to clamp and fix the ton tank. When the hydraulic or pneumatic system fails, it is easy for the ton tank to loosen and fall, causing serious safety accidents. At the same time, long-term loading of hydraulic or pneumatic systems increases the risk of leakage and accelerates the wear of hydraulic or pneumatic components.

[0004] (2) It is easy to damage the surface of the ton tank. Since ton tanks are usually made of materials such as polyethylene, when the pressure of the device on the ton tank is too large, it is easy to cause damage or deformation on the surface of the ton tank, reducing the yield rate of ton tanks.

[0005] Therefore, there is an urgent need for a clamping device for ton tank production to solve the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to address the problem that existing devices usually use hydraulic or pneumatic methods to clamp and fix ton tanks. When the hydraulic or pneumatic system fails, it is easy for the ton tank to loosen and fall, causing serious safety accidents. At the same time, long-term loading of hydraulic or pneumatic systems increases the risk of leakage and accelerates the wear of hydraulic or pneumatic components.

[0007] To achieve the above-mentioned invention purpose, the utility model provides the following technical solutions:

[0008] A clamping device for ton tank production, including a connecting seat, and further including:

[0009] A chassis, fixed to the bottom end of the connecting seat, and both sides of the top end of the chassis are rotatably connected with first pneumatic telescopic rods;

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0021] In the solution of the present application:

[0022] 1. The second pneumatic telescopic rod is pushed to move the rocker arm towards the second rotating shaft, so that the rocker arm drives the clamping jaw to clamp the second rotating shaft. At the same time, the teeth increase the friction between the second rotating shaft and the clamping jaw, thereby realizing the automatic locking function of this device, facilitating the fixing of the position of the second rotating shaft after clamping, reducing the burden on the first pneumatic telescopic rod, and at the same time, when the hydraulic or pneumatic system fails, it can provide additional safety protection and improve the reliability and safety of clamping.

[0023] 2. It contracts under the double extrusion of the pressure plate and the clamping plate through a rigid spring, reducing the pressure of the pressure plate on the ton container, making the ton container not easily deformed. Thus, the clamping and buffering function of this device is realized, restricting the pressure exerted on the ton container by the buffering structure, making it not easy for scratches or deformations to occur on the surface of the ton container, and improving the yield rate of ton containers.

Detailed Description of the Embodiment

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0030] As Figures 1-4 shown, a clamping device for ton container production proposed in this embodiment includes a connecting seat 1, and further includes:

[0031] A chassis 7, fixed to the bottom end of the connecting seat 1, and both sides of the top end of the chassis 7 are rotatably connected with a first pneumatic telescopic rod 2;

[0032] Rotating seats 8, fixed to both sides of the chassis 7, and a second rotating shaft 10 is rotatably connected inside the rotating seats 8. Connecting frames 4 are fixed to the outer sides of the second rotating shafts 10, and reinforcing strips 11 are fixed to one side of each connecting frame 4;

[0033] A first rotating shaft 3, fixed inside the top end of the connecting frame 4;

[0034] The clamping plate 6 is fixed to the bottom end on one side of the connecting frame 4;

[0035] The locking structure 9 is arranged on both sides of the chassis 7. Among them, the locking structure 9 includes teeth 904 fixed on the outer side of the second rotating shaft 10, fixing plates 906 installed on both sides inside the chassis 7, a power assembly installed on one side of the fixing plates 906, and clamping jaws 905 sleeved on the outer side of the second rotating shaft 10 and connected to the power assembly;

[0036] The buffer structure 5 is arranged on one side of the clamping plate 6 and is used to limit the pressure exerted by the clamping plate 6 on the ton tank.

[0037] As Figure 1 、 Figure 2 and Figure 4 shown, as a preferred embodiment, on the basis of the above method, further, the power assembly includes a second pneumatic telescopic rod 901 installed inside the fixing plate 906, a push arm 903 rotatably connected to one side of the fixing plate 906 and connected to the clamping jaw 905, and a rocker arm 902 rotatably connected to the mobile end of the second pneumatic telescopic rod 901 and connected to the push arm 903. A rotating structure is formed between the rocker arm 902 and the push arm 903. The clamping jaws 905 are symmetrically distributed on the horizontal center line of the second rotating shaft 10. By starting the second pneumatic telescopic rod 901 to extend, the second pneumatic telescopic rod 901 pushes the rocker arm 902 towards the second rotating shaft 10. At the same time, the rocker arm 902 drives the clamping jaw 905 to approach the second rotating shaft 10 through the push arm 903, so that the upper and lower groups of clamping jaws 905 clamp the second rotating shaft 10. At the same time, the teeth 904 increase the friction between the second rotating shaft 10 and the clamping jaw 905, making the second rotating shaft 10 not easy to loosen during the locking process.

[0038] As Figure 1 、 Figure 2 and Figure 3 shown, as a preferred embodiment, on the basis of the above method, further, the buffer structure 5 includes a guide rod 502 installed inside one side of the clamping plate 6, the guide rod 502 inserted inside the housing 501, a pressing plate 504 fixed on one side of the guide rod 502, a rubber pad 505 installed on one side of the pressing plate 504, and a rigid spring 503 installed inside the housing 501 and connected to the pressing plate 504. The pressing plate 504 forms a telescopic structure with the clamping plate 6 through the rigid spring 503. The rigid springs 503 are equally spaced on one side of the pressing plate 504. By using the pressing plate 504 and the rubber pad 505 to directly contact the ton tank instead of the clamping plate 6, and at the same time, the rigid spring 503 transmits the force of the clamping plate 6 to the pressing plate 504. When the pressure applied by the clamping plate 6 is too large, the rigid spring 503 is squeezed and contracted by the double extrusion of the pressing plate 504 and the clamping plate 6, reducing the pressure of the pressing plate 504 on the ton tank and making the ton tank not easy to deform. The movement of the pressing plate 504 is guided by the guide rod 502, and the surface of the pressing plate 504 is not easy to be scratched by the rubber pad 505.

[0039] The first rotating shaft 3 is rotatably connected to the first pneumatic telescopic rod 2, and the connecting frame 4 and the second rotating shaft 10 are integrally welded.

[0040] Specifically, when the clamping device for ton tank production is in use: Connect the connecting seat 1 to the hoisting equipment, use the hoisting equipment to move the position of the device, place the device outside the ton tank, start the first pneumatic telescopic rod 2 to extend, so that the first pneumatic telescopic rod 2 pushes the connecting frame 4 to rotate around the axis of the second rotating shaft 10 through the first rotating shaft 3. At the same time, the connecting frame 4 drives the clamping plates 6 to clamp the ton tank from both left and right sides, and at the same time, the buffer structure 5 buffers the pressure caused by the clamping plates 6. After the clamping is completed, the angle of the second rotating shaft 10 is fixed through the locking structure 9, so that the position between the second rotating shaft 10 and the rotating seat 8 is fixed, reducing the load on the first pneumatic telescopic rod 2.

[0041] By starting the second pneumatic telescopic rod 901 to extend, the second pneumatic telescopic rod 901 pushes the rocker arm 902 towards the second rotating shaft 10. At the same time, the rocker arm 902 drives the clamping jaw 905 to approach the second rotating shaft 10 through the push arm 903, so that the upper and lower groups of clamping jaws 905 clamp the second rotating shaft 10. At the same time, the teeth 904 increase the friction force between the second rotating shaft 10 and the clamping jaw 905, making the second rotating shaft 10 not easy to loosen during the locking process;

[0042] The pressure plate 504 and the rubber pad 505 are used to directly contact the ton tank instead of the clamping plate 6. At the same time, the rigid spring 503 transmits the force of the clamping plate 6 to the pressure plate 504. When the pressure applied by the clamping plate 6 is too large, the rigid spring 503 is squeezed by both the pressure plate 504 and the clamping plate 6 and contracts, reducing the pressure of the pressure plate 504 on the ton tank, making the ton tank not easy to deform. The movement of the pressure plate 504 is guided by the guide rod 502, and the surface of the pressure plate 504 is not easy to be scratched by the rubber pad 505.

[0043] The above embodiments are only used to illustrate the present invention and do not limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above-mentioned respective embodiments, the present invention is not limited to the above specific implementation manners.
