Description

Technical Field

[0001] The utility model belongs to the field of steel metallurgy, and in particular relates to a large-package skateboard oil cylinder piston rod adapter. Background Art

[0002] The ladle flow control device includes components such as the slide mechanism, the slide mechanism cylinder seat, the slide mechanism cylinder seat connecting rod, the slide cylinder, and the slide cylinder piston rod. After the slide cylinder piston rod and the connecting rod are connected, the push-pull connecting rod controls the opening and closing of the slide mechanism, thereby achieving precise control of the outflow and cutoff of molten steel. When a steel plant upgrades the ladle slide mechanism, the slide mechanism stroke and the cylinder seat connecting rod head will change and become inconsistent with the original dimensions. If the newly modified cylinder structure is used, the old slide mechanism stroke will not be compatible without an adapter. However, the upgrade and technical transformation of all the slide mechanisms in a steel plant cannot be completed in a short period of time and will inevitably require a certain period of time. The upgrade process involves two slide mechanisms. If they cannot be used interchangeably, the normal production order of the steel plant will inevitably be disrupted, causing inconvenience to the on-site production organization and operation. To ensure that both the new and old slide mechanisms can be used during the transformation, a large ladle slide cylinder piston rod adapter must be provided. Utility Model Content

DETAILED DESCRIPTION

[0016] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention.

[0017] To achieve the above purpose, the utility model piston rod adapter, such as Figure 1 、 Figure 2 As shown, the details are as follows:

[0018] The piston rod adapter 3 includes a slide cylinder piston rod slot 7 and a slide mechanism connecting rod slot 8, which is used to quickly connect the large slide cylinder piston rod and the slide mechanism cylinder seat connecting rod. When the piston rod and connecting rod cannot be directly connected, the adapter is used to achieve quick connection.

[0019] The skateboard cylinder piston rod slot 7 is connected to the skateboard cylinder piston rod 2, and the skateboard mechanism connecting rod slot 8 is connected to the skateboard mechanism connecting rod 4; the skateboard cylinder piston rod slot 7 is a groove shape that is not opened to the root, and the skateboard mechanism connecting rod slot 8 is a groove shape that is opened to the bottom.

[0020] The base of the skateboard cylinder 1 is fixed to the skateboard mechanism cylinder seat 5 by bolts, and the T-shaped head end of the skateboard cylinder piston rod 2 is connected to the skateboard cylinder piston rod slot 7 of the piston rod adapter 3 by snapping.

[0021] One end of the slide mechanism connecting rod 4 is connected to the slide mechanism connecting rod slot 8 of the piston rod adapter 3 by a snap buckle, and the other end of the slide mechanism connecting rod 4 is connected to one end of the slide mechanism cylinder seat 5 by a bolt.

[0022] The other end of the slide mechanism oil cylinder seat 5 is connected to the slide mechanism 6 through bolts.

[0023] The material of the piston rod adapter 3 is 40CrMo.

[0024] During use, first extend the slide cylinder piston rod 2 of the slide cylinder 1 to its maximum stroke position, and retract the slide mechanism connecting rod 4, which controls the opening and closing of the slide mechanism 6, to the closed position of the slide mechanism 6 water outlet. Then, mate the slide mechanism connecting rod slot 8 of the piston rod adapter 3 with the slide mechanism connecting rod 4; adjust the slide cylinder piston rod 2 to the appropriate size (depending on the length of the adapter, adjust it to a position that allows the piston rod adapter 3 and the slide cylinder piston rod slot 7 to fit conveniently), and then mate the piston rod adapter 3 with the slide cylinder piston rod slot 7; at this point, the docking of the slide cylinder piston rod 2 and the slide mechanism connecting rod 4 is complete.

[0025] The utility model realizes that the slide plate oil cylinder can be docked with the upgraded slide plate mechanism connecting rod without modification or replacement. That is, the slide plate oil cylinder piston rod and the slide plate mechanism connecting rod are docked, avoiding the modification or replacement of the slide plate oil cylinder, and improving the safety and stability of the equipment.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
