Description
Technical field
This utility model belongs to safety guard technical field, is specifically related to a kind of lifting being applied to sports equipment
Safety guard on machine.
Background technology
Along with the raising day by day of present civil engineering cost, cause the safe distance of the end carriage of crane and Factory Building bracket beam very
Little, cause people can not pass through Factory Building bracket beam with end carriage simultaneously.When operator carry out service work to crane facility, one
Denier occurs that maloperation, end carriage are moved, and easily operator is caused personal injury, even drops from bracket beam, causes personnel
Casualty accident.In recent years, this accident happens occasionally, the most good solution.
Summary of the invention
This utility model is aiming at the problems referred to above, it is provided that a kind of simple in construction, highly reliable, the crane that safety is good
Automatic stopping safety device.
In order to realize above-mentioned purpose of the present utility model, this utility model adopts the following technical scheme that, this utility model bag
Include housing, it is characterised in that: being provided with slide bar in housing, slide bar surface configuration has ratchet；Set corresponding to ratchet in described housing
Put the ratchet with back-moving spring；It is additionally provided with mounting seat in described housing, mounting seat is provided with photoswitch；Described slide bar
On be provided with the switch coordinated with photoswitch close to plate.
As a kind of preferred version of the present utility model, between described slide bar and housing, it is provided with thrust spring.
As another kind of preferred version of the present utility model, the end of described slide bar passes mounting seat, and is provided with and pacifies
The limiting plate that dress seat matches.
The beneficial effects of the utility model: when 1, this utility model uses, secure the housing on crane, and at slide bar
End connect rope；When crane maloperation occurs or starts, operator pull rapidly rope, can be established by cable by light
Close control crane to quit work, high safety.
2, due to construction features of the present utility model, this utility model can only manually reset, and just can make crane again
Secondary startup, improves security performance of the present utility model further.
3, this utility model is by being provided with thrust spring between slide bar and housing, it is ensured that ratchet and ratchet are protected all the time
Hold 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, this utility model 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,
Reset easily.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional view of the present utility model.
Fig. 3 is use state diagram of the present utility model.
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 for reset bullet
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 for rope.
Detailed description of the invention
This utility model 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 in described housing 2
9, 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 kind of preferred version of the present utility model, between described slide bar 3 and housing 2, it is provided with thrust spring 4.
As another kind of preferred version of the present utility model, the end of described slide bar 3 passes mounting seat 9, and be provided with
The limiting plate 11 that mounting seat 9 matches.
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 plate 7 on slide bar 3
And between mounting seat 9, it being provided with the second spacer pin 8, described switch is arranged on the second alignment pin close to plate 7.
When this utility model uses, it is fixed to housing 2 one end of crane 14, then connect slide bar by a rope 15
Connection ring 1 on 3, the other end of rope 15 is connected with the other end of crane 14；Open because of reasons such as maloperations when crane 14
Time dynamic, operator only need to pull steel wire rope, and slide bar 3 drives switch close to plate 7 principle photoswitch 10, photoswitch
10 control crane 14 stops action；Now under the effect of ratchet 13, ratchet 12 and thrust spring 4, slide bar 3 is made to keep not
Dynamic.After operator confirm safety, manually adjust ratchet 13, ratchet 12, then control slide bar 3 return, make switch close to plate 7
Close to each other with photoswitch 10, now crane 14 receives the signal of photoswitch 10, can be again started up.
It is understood that above with respect to specific descriptions of the present utility model, be merely to illustrate this utility model and not
It is limited to the technical scheme described by this utility model embodiment, it will be understood by those within the art that, the most permissible
This utility model is modified or equivalent, to reach identical technique effect；Needs are used, all in this reality as long as meeting
Within novel protection domain.
