Description

Technical Field

[0001] The utility model relates to the technical field of safety limit auxiliary tools for cylinder maintenance, and specifically relates to a cylinder anti-closing limit tooling. Background Art

[0002] A cylinder is one of the commonly used actuators in the field of industrial automation. It generates linear or rotational motion through compressed air and is widely used in various mechanical devices, such as assembly lines, packaging machines, robots, etc. In the application of cylinders, in order to avoid collisions or damages caused by excessive strokes and to ensure the accuracy and repeatability of cylinder movements, the use of limit devices becomes crucial.

[0003] Cylinders are widely used in the power energy equipment of steel rolling heating furnaces. For example, the furnace door, heat preservation cover, reversing valve, steel stopping hook, etc. use cylinders as the driving force for operation. Since the movement of the cylinder is driven by air pressure to push the piston, when performing maintenance operations on the cylinder control equipment, it is necessary to close the cylinder air source to prevent misoperation.

[0004] During actual maintenance operations, when the cylinder needs to be in the closed state, the reliable stationary state of the equipment can be achieved as long as the cylinder air source is closed; while when the cylinder needs to be in the open state, if the air source is closed, there may be internal air leakage causing the cylinder to close slowly, and if the air source is not closed, there may be a risk of misoperation causing the cylinder to move, both of which may pose safety risks to the operators.

[0005] Therefore, there is an urgent need to design a cylinder anti-closing limit tooling to solve the problem of potential safety hazards caused by workers' misoperation resulting in cylinder movement. Summary of the Utility Model

[0006] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a cylinder anti-closing limit tooling.

[0007] The technical solution adopted by the utility model to solve its technical problems is: a cylinder anti-closing limit tooling, including a limit sleeve, a lock and a hinge. The limit sleeve is two sector-shaped pieces obtained by cutting a tubular sleeve. The lock is arranged on the openable side of the two sector-shaped pieces, and the hinge connects the two sector-shaped pieces together. A handle is arranged outside the limit sleeve.

[0008] Specifically, the limit sleeve is divided into left and right parts. A limit hole is provided at the upper end of the limit sleeve, and the lower end opening of the limit sleeve is the same size as the cylinder sealing sleeve.

[0009] Specifically, the upper plate of the limit sleeve is composed of two steel plates with semi-circular openings. The semi-circular openings in the middle of the two steel plates face each other to form a limit hole.

[0010] Specifically, the latch is installed in the direction where the two segments of the limit sleeve can be opened and closed, and a male latch and a female latch are respectively provided on the two segments.

[0011] Specifically, the hinge is installed on the other side of the limit sleeve where the latch is installed, and the hinge connects the two segments together.

[0012] Specifically, the handle is connected to the outside of the limit sleeve for easy access during use.

[0013] The utility model has the following beneficial effects:

[0014] The cylinder anti-closing limit tooling designed by the utility model: 1. Effectively locks the position of the cylinder, prevents misoperation, and realizes the intrinsic safety of the operation; 2. Simple to operate, and can be completed without any tools. Description of the Drawings
