Abstract
The utility model discloses a spring self-locking compression rod, belongs to the technical field of self-locking devices, and particularly relates to the spring self-locking compression rod. The spring self-locking compression rod can avoid the phenomenon that under the condition of air supply failure, production accidents happen in a grab bucket mechanism. The spring self-locking compression rod comprises a lower earring and is characterized in that the lower earring is connected with a guide sleeve which is arranged above the lower earring, and a support is arranged in the guide sleeve and can move up and down. The upper end of the support is connected with an upper earring, and a spring is arranged between the upper earring and the lower earring, and the lower earring is arranged outside the guide sleeve.
Description
Technical field
The utility model belongs to the self-locking device technical field, relates in particular to a kind of spring self-lock compression link.
Background technology
The aluminum electrolysis multifunctional crane group is the key equipment that large-scale aluminium electrolysis is produced, and is bearing auxiliary large-sized prebaked cell for aluminum-reduction production operation task.Along with the future development of the cell technologies in the aluminium industry processed towards large capacity prebaked cell technology, guarantee prebaked cell modernization, high efficiency steady production; Require aluminum electrolysis multifunctional crane to possess more complete function.
The grab bucket mechanism of existing aluminum electrolysis multifunctional crane slag cleaning device adopts cylinder control bucket body to open and close; Because of its machinery-free self-locking device, when source of the gas broke down, the bucket body of grab bucket can be opened because of Action of Gravity Field in the working process, caused serious industrial accident.
Summary of the invention
The utility model is exactly for the problems referred to above, provides a kind of mechanism that prevents from grabbing bucket that the spring self-lock compression link of industrial accident occurs under the state of air failure.
For achieving the above object, the utility model adopts following technical scheme, and the utility model comprises lower earrings, and earrings links to each other with the orienting sleeve of its top under its structural feature, but is provided with the pillar of up-and-down movement in the orienting sleeve, and the pillar upper end links to each other with upper earrings; Be provided with spring between the lower earrings in the orienting sleeve outside and the upper earrings.
As a kind of preferred version, but be provided with the intermediate sleeve of up-and-down movement in the orienting sleeve described in the utility model, intermediate sleeve top internal diameter is less than the middle and lower part internal diameter; But be provided with the limiting stopper of up-and-down movement in the intermediate sleeve middle and lower part, limiting stopper is fixed on the lower end of described pillar, and the diameter of limiting stopper is greater than intermediate sleeve top internal diameter.
The utility model beneficial effect: when the utility model used, lower earrings linked to each other with the grab machine permanent seat, and upper earrings links to each other with the grab machine connecting rod.When the grab machine connecting rod when anchor shaft rotates, transmitting torque is applied to earrings, upper earrings Compress Spring, and drive the utility model rotates to an angle, cross spring maximum compression point rear spring resilience elongation, make the utility model and grab machine connecting rod form mechanical self-latching.Even the air cylinder air source fault occurs, the effect of cylinder get out of hand, grab bucket can not be subjected to gravity and closure or openness cause industrial accident yet, and is safe and reliable.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described further.The utility model protection domain not only is confined to the statement of following content.
Fig. 1 is the utility model compressive state structural representation.
Fig. 2 is that the utility model stretches out the status architecture schematic diagram.
Fig. 3 is that the utility model uses constitution diagram.
Among the figure, 1 is that lower earrings, 2 is that limiting stopper, 3 is that orienting sleeve, 4 is that pillar, 5 is that intermediate sleeve, 6 is that spring, 7 is that upper earrings, 8 is that grab machine connecting rod, 9 is the grab machine permanent seat.
The specific embodiment
As shown in the figure, the utility model comprises lower earrings 1, and lower earrings 1 links to each other with the orienting sleeve 3 of its top, but is provided with the pillar 4 of up-and-down movement in the orienting sleeve 3, and pillar 4 upper ends link to each other with upper earrings 7; Be provided with spring 6 between the lower earrings 1 in orienting sleeve 3 outsides and the upper earrings 7.
But be provided with the intermediate sleeve 5 of up-and-down movement in the described orienting sleeve 3, intermediate sleeve 5 top internal diameters are less than the middle and lower part internal diameter; But be provided with the limiting stopper 2 of up-and-down movement in intermediate sleeve 5 middle and lower parts, limiting stopper 2 is fixed on the lower end of described pillar 4, and the diameter of limiting stopper 2 is greater than intermediate sleeve 5 top internal diameters., intermediate sleeve 5 can increase the variation range of upper earrings 7 and lower earrings 1 relative position by being set, and easy to use; And need not the long orienting sleeve 3 of the higher large hardness of cost of manufacture and pillar 4.
Described orienting sleeve 3 can be installed on the lower earrings 1 by latching member; Connect reliable.
Below in conjunction with description of drawings the utility model one-off process: lower earrings 1 is linked to each other with grab machine permanent seat 9, and upper earrings 7 links to each other with grab machine connecting rod 8.
When the air cylinder air source fault occurring, the cylinder get out of hand is done the time spent, and spring 6 can change the loading angle of grab machine connecting rod 8, forms mechanical self-latching; Grab bucket can because being subjected to the gravity closure or openness, not cause industrial accident.
Be understandable that, above about specific descriptions of the present utility model, only for the utility model being described and being not to be subject to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
