Description

A multistage blocking device of start-stop button for colliery is combined and is adopted equipment

The technical field is as follows:

the utility model relates to a coal mining equipment technical field in the pit especially relates to a start-stop button multistage blocking device for colliery is fully mechanized and is adopted equipment.

Background art:

in the technical field of coal mining under a coal mine, when equipment such as a coal mining machine, a hydraulic support and a conveyor on a fully mechanized mining face is overhauled, a plurality of people are often required to simultaneously lock a start-stop button of a scraper conveyor, because a production line is long, the start-stop button of the prior art can only be locked once, cross operation is often required in the actual working process, if a certain post is overhauled or whether other posts are still overhauled, unlocking and locking faults have great potential safety hazards (for example, an overhauler A needs to overhaul the coal mining machine firstly, the overhauler A needs to lock the start-stop button of the scraper conveyor at the moment and then goes to the coal mining machine for overhauling, in the overhauling process of the overhauler A, the overhauler B needs to overhaul the hydraulic support, and when the overhauled start-stop button of the scraper conveyor is seen to be locked, the overhauled operation is carried out directly to the hydraulic support, at this moment, the overhaul of the maintainer A is finished and the start-stop button of the scraper conveyor is returned to start operation, the maintainer A does not know that the maintainer B is overhauling, and the scraper conveyor operates to cause the maintainer B to have huge potential safety hazards and life risks).

The utility model has the following contents:

an object of the utility model is to provide a multistage blocking device of start-stop button for colliery is fully mechanized and is adopted equipment.

The content of the utility model is as follows: the utility model provides a multistage blocking device of start-stop button for colliery is fully mechanized and is adopted equipment, its includes protective case, the concentric suit of protective case is outside the start-stop button, protective case fixed mounting is on the equipment box protective case's bottom fixed mounting has the mounting panel the first lockhole of a plurality of has been seted up along the width direction equipartition on the mounting panel protective case's the horizontal fixed mounting in top has the round pin axle, round pin axle and apron swivelling joint, the interior face of apron with protective case's outer terminal surface is laminated mutually the apron on seted up with the second lockhole of first lockhole one-to-one.

Further, seted up hemispherical positioning hole on the mounting panel the perpendicular outside fixedly connected with protruding post of the planking face of apron the interior face of apron is improved level and has been seted up the installation blind hole, the installation blind hole extends to the inside of protruding post install compression spring and spacing ball from inside to outside in the installation blind hole in proper order the drill way department of installation blind hole installs the spacing ring, the hole diameter of spacing ring is less than the diameter of spacing ball works as the apron is rotatory and makes spacing ball gets into when in the positioning hole, the apron will protective case covers completely and first lockhole with the concentric alignment of second lockhole one-to-one.

The utility model has the advantages that: the utility model discloses simple structure opens and stops the button position and install multistage blocking device for opening and stopping the button and can realize shutting many times, effectively avoided the cross operation in-process to appear opening and stopping the phenomenon of button maloperation, stop the potential safety hazard, guarantee operating personnel's life safety; and the locking device is designed into a quick positioning device, the operation process is quick and convenient, and the locking device is worthy of being popularized and used in a large range.

Description of the drawings:

fig. 1 is a perspective view of the present invention;

FIG. 2 is a sectional view of the mounting structure of the limiting ball of the present invention;

in the figure, a protective sleeve 1, a start-stop button 2, an equipment box body 3, a mounting plate 4, a first lock hole 5, a pin shaft 6, a cover plate 7, a second lock hole 8, a positioning pit 9, a protruding column 10, a mounting blind hole 11, a compression spring 12, a limiting ball 13 and a limiting ring 14.

The specific implementation mode is as follows:

as shown in fig. 1 and 2, a multi-stage locking device for a start-stop button of a fully mechanized mining device for a coal mine comprises a protective sleeve 1, wherein the protective sleeve 1 is concentrically sleeved outside the start-stop button 2, the protective sleeve 1 is fixedly installed on a device box 3, an installation plate 4 is fixedly installed at the bottom end of the protective sleeve 1, a plurality of first locking holes 5 are uniformly distributed on the installation plate 4 along the width direction, a pin shaft 6 is horizontally and fixedly installed at the top end of the protective sleeve 1, the pin shaft 6 is rotatably connected with a cover plate 7, the inner plate surface of the cover plate 7 is attached to the outer end surface of the protective sleeve 1, and second locking holes 8 corresponding to the first locking holes 5 one by one are formed in the cover plate 7; offer hemispherical positioning hole 9 on the mounting panel 4 the perpendicular outside fixedly connected with protruding post 10 of the planking face of apron 7 the interior face of apron 7 is improved level and has been offered installation blind hole 11, installation blind hole 11 extends to the inside of protruding post 10 install compression spring 12 and spacing ball 13 from inside to outside in proper order in the installation blind hole 11 the drill way department of installation blind hole 11 installs spacing ring 14, spacing ring 14's bore diameter is less than spacing ball 13's diameter, works as apron 7 is rotatory and makes spacing ball 13 gets into when in the positioning hole 9, apron 7 will protective case 1 covers completely and first lockhole 5 with the concentric alignment of second lockhole 8 one-to-one.
