Abstract
The invention discloses a dismounting device for chain links. The device comprises a base, an abutting member and a lead screw, wherein the base is provided with an opening on one side, a groove is arranged in the middle on the lower portion of the opening, and bosses are arranged on two sides of the groove; two abutting teeth are arranged on the lower plane of the abutting member, and the external side of the inner abutting tooth is extended to form a tooth groove; the abutting teeth correspond to the groove, and the bosses correspond to the tooth groove; and a screw hole is arranged at the top of the base and rotarily matched with the lead screw, and the screwing-in end of the lead screw is matched with the abutting member in an abutting mode. According to the dismounting device, a structure of the base, the abutting member and the lead screw is adopted, during utilization, one chain link is suspended, and two sides of the other chain link are placed on the bosses. The lead screw abuts to the abutting member when screwed down, two abutting teeth of the abutting member abuts respectively to two sides of the suspended chain link, and finally the chain link is separated from the other chain link. The dismounting device is high in dismounting efficiency and not easy to damage the chain links.
Description
Technical field
The present invention relates to a kind of extracting tool, particularly dismantle the device of cable link.
Background technology
Cable link is a production apparatus indispensable under the coal mine.Anchor chain by two same structures is formed, and the profile of each anchor chain is " C " shape opening, and the side, two ends of opening part is equipped with the profile of tooth caulking groove, and two anchor chains are chimeric through the profile of tooth caulking groove to be one, promptly forms cable link.Because the underground work humid environment, the working time one is long, and cable link can get rusty in various degree, and very difficult during dismounting, the workpeople can only beat with hammer, after becoming flexible it is pulled down, and not only wastes time and energy, and also damages cable link easily.Up to the present, do not see that also special-purpose extracting tool is arranged.
Summary of the invention
The purpose of this invention is to provide the high and not provision for disengagement of the cable link of rapid wear ring cable link of a kind of removal efficiency.
Technical scheme of the present invention is: comprise pedestal, top-pressure part and leading screw, said pedestal one side opening is provided with groove in the middle of the bottom of its opening, and the groove both sides are boss; Said top-pressure part lower plane is provided with two apical tooths, and the apical tooth outside of an inner side is extended with teeth groove; Apical tooth is corresponding with groove, and boss is corresponding with teeth groove; The pedestal top is provided with screw, and leading screw cooperates with the screw rotation, and the leading screw screw terminal cooperates with the top-pressure part roof pressure.
Owing to adopt the structure of pedestal, top-pressure part and leading screw among the present invention.During use; The one side of the cable link that is made up of two anchor chains lies on the boss plane of pedestal, makes one side of an anchor chain aim at the groove of pedestal, and another side is unsettled outside pedestal; And the boss in the groove outside is just in time relative with this anchor chain intermediate hollow position, and promptly this anchor chain is in vacant state.At this moment, the both sides of another anchor chain are placed on respectively on two boss naturally.When screwing off leading screw, leading screw roof pressure top-pressure part withstands on the both sides of the anchor chain that is in vacant state two apical tooths of top-pressure part respectively, and its top makes it separate with another anchor chain down the most at last.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the decomposing schematic representation of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further explain, but do not constitute any restriction of the present invention.Illustrated in figures 1 and 2, the present invention includes pedestal 1, top-pressure part 2 and leading screw 3, said pedestal 1 one side openings are provided with groove in the middle of the bottom of its opening, and the groove both sides are boss; Said top-pressure part 2 lower planes are provided with two apical tooths, and the apical tooth outside of an inner side is extended with teeth groove; Apical tooth is corresponding with groove, and boss is corresponding with teeth groove; Pedestal 1 top is provided with screw, and leading screw 3 cooperates with the screw rotation, and leading screw 3 screw terminals cooperate with top-pressure part 2 roof pressures.
During operation; The one side of the cable link that is made up of two anchor chains lies on the plane that two boss of pedestal 1 constitute; Make the groove of one side aligning pedestal 1 of an anchor chain; Another side is unsettled outside pedestal 1, and the boss in the groove outside is just in time relative with this anchor chain intermediate hollow position, and promptly this anchor chain is in vacant state.At this moment, the both sides of another anchor chain are placed on respectively on two boss naturally.When screwing off leading screw 3, leading screw 3 roof pressure top-pressure parts 2 withstand on the both sides of the anchor chain that is in vacant state two apical tooths of top-pressure part 2 respectively, and its top makes it separate with another anchor chain down the most at last.
