Description
Technical field
The invention belongs to safety guard technical field, be specifically related to the safety guard on a kind of crane being applied to sports equipment.
Background technology
Along with the raising day by day of present civil engineering cost, the end carriage causing crane is the least with the safe distance of Factory Building bracket beam, causes people can not pass through Factory Building bracket beam with end carriage simultaneously.When operator carry out service work to crane facility, maloperation once occur, end carriage moves, and easily operator is caused personal injury, even drops from bracket beam, and cause casualties accident.In recent years, this accident happens occasionally, the most good solution.
Summary of the invention
The present invention is aiming at the problems referred to above, it is provided that a kind of simple in construction, highly reliable, the crane automatic stopping safety device that safety is good.
In order to realize the above-mentioned purpose of the present invention, the present invention adopts the following technical scheme that, the present invention includes housing, it is characterised in that: being provided with slide bar in housing, slide bar surface configuration has ratchet；The ratchet with back-moving spring is set corresponding to ratchet in described housing；It is additionally provided with mounting seat in described housing, mounting seat is provided with photoswitch；The switch coordinated with photoswitch it is provided with close to plate on described slide bar.
As a preferred embodiment of the present invention, between described slide bar and housing, it is provided with thrust spring.
As the another kind of preferred version of the present invention, the end of described slide bar passes mounting seat, and is provided with the limiting plate matched with mounting seat.
Beneficial effects of the present invention: when 1, the present invention uses, secures the housing on crane, and connects rope in the end of slide bar；When crane maloperation occurs or starts, operator pull rapidly rope, can control crane by photoswitch and quit work, high safety.
2, due to the construction features of the present invention, the present invention can only manually reset, and crane just can be made to be again started up, and improves the security performance of the present invention further.
3, the present invention is by being provided with thrust spring between slide bar and housing, it is ensured that ratchet and ratchet remain close contact, thus ensure slide bar will not back and forth vibration and only cause crane mistakenly stop, or the problem such as the most pneumatic.
4, the present invention is by being provided with limiting plate in slide bar end, it is ensured that slide bar will not be drawn out, easy to use, resets easily.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the sectional view of the present invention.
Fig. 3 is the use state diagram of the present invention.
In accompanying drawing 1 for connect ring, 2 be housing, 3 be slide bar, 4 be thrust spring, 5 be the first spacer pin, 6 be back-moving spring, 7 for switch close to plate, 8 be the second spacer pin, 9 be mounting seat, 10 be limiting plate for photoswitch 11,12 be ratchet, 13 be ratchet, 14 be crane, 15 be rope.
Detailed description of the invention
The present invention includes housing 2, it is characterised in that: being provided with slide bar 3 in housing 2, slide bar 3 surface configuration has ratchet 13；The ratchet 12 with back-moving spring 6 is set corresponding to ratchet 13 in described housing 2；It is additionally provided with mounting seat 9 in described housing 2, mounting seat 9 is provided with photoswitch 10；The switch coordinated with photoswitch 10 it is provided with close to plate 7 on described slide bar 3.
As a preferred embodiment of the present invention, between described slide bar 3 and housing 2, it is provided with thrust spring 4.
As the another kind of preferred version of the present invention, the end of described slide bar 3 passes mounting seat 9, and is provided with the limiting plate 11 matched with mounting seat 9.
The end of described slide bar 3 is stretched out outside housing 2, and is provided with connection ring 1.
On described slide bar 3, thrust spring 4 is provided with the first spacer pin 5；Corresponding to switch close to being provided with the second spacer pin 8 between plate 7 and mounting seat 9 on slide bar 3, described switch is arranged on the second alignment pin close to plate 7.
When the present invention uses, being fixed to housing 2 one end of crane 14, then connect the connection ring 1 on slide bar 3 by a rope 15, the other end of rope 15 is connected with the other end of crane 14；When crane 14 starts because of reasons such as maloperations, operator only need to pull steel wire rope, and slide bar 3 drives switch close to plate 7 principle photoswitch 10, and photoswitch 10 controls crane 14 and stops action；Now under the effect of ratchet 13, ratchet 12 and thrust spring 4, slide bar 3 is made to remain stationary as.After operator confirm safety, manually adjusting ratchet 13, ratchet 12, then control slide bar 3 return, make switch close to each other with photoswitch 10 close to plate 7, now crane 14 receives the signal of photoswitch 10, can be again started up.
It is understandable that, above with respect to the specific descriptions of the present invention, it is merely to illustrate the present invention and is not limited to the technical scheme described by the embodiment of the present invention, it will be understood by those within the art that, still the present invention can be modified or equivalent, to reach identical technique effect；Needs are used, all within protection scope of the present invention as long as meeting.
