Description
Technical field
The invention belongs to safety guard technical field, and in particular to a kind of to be applied on the crane of sports equipment
Safety guard.
Background technology
With the increasingly raising of present civil engineering cost, the safe distance of the end carriage of crane and factory building bracket beam is caused very
It is small, cause people simultaneously to pass through factory building bracket beam with end carriage.When operating personnel carry out service work to crane facility, one
There is maloperation in denier, and end carriage movement easily causes personal injury to operating personnel, or even is dropped from bracket beam, causes personnel
Casualty accident.In recent years, this accident happens occasionally, but never good solution.
The content of the invention
The present invention is aiming above mentioned problem, there is provided a kind of simple structure, highly reliable, the good crane of security is automatic
Parking safety guard.
In order to realize above-mentioned purpose of the invention, the present invention is adopted the following technical scheme that, the present invention includes housing, its feature
It is：Slide bar is provided with housing, slide bar surface is provided with ratchet；Being set corresponding to ratchet in the housing has back-moving spring
Ratchet；Mounting seat is additionally provided with the housing, optoelectronic switch is provided with mounting seat；It is provided with the slide bar and photoelectricity
The switch for coordinating is switched close to plate.
As a preferred embodiment of the present invention, thrust spring is provided between the slide bar and housing.
Used as another preferred scheme of the invention, the end of the slide bar passes through mounting seat, and is provided with and mounting seat
The limiting plate being engaged.
Beneficial effects of the present invention：1st, when the present invention is used, secure the housing on crane, and connect in the end of slide bar
Splicing rope；When crane maloperation occurs or starts, operating personnel pull rapidly rope, you can controlled by optoelectronic switch
Heavy-duty machine is stopped, high safety.
2nd, due to design feature of the invention, the present invention can only manually reset, and crane can just be again started up, and enter
One step improves security performance of the invention.
3rd, the present invention between slide bar and housing by being provided with thrust spring, it is ensured that ratchet and ratchet remain tight
Contiguity touch so that ensure slide bar will not back and forth vibration and cause crane mistakenly stop to stop, or by mistake it is pneumatic the problems such as.
4th, the present invention is provided with limiting plate by slide bar end, it is ensured that slide bar will not be drawn out, easy to use, resets
Easily.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is sectional view of the invention.
Fig. 3 is use state figure of the invention.
In accompanying drawing 1 be connection ring, 2 be housing, 3 be slide bar, 4 be thrust spring, 5 be the first spacer pin, 6 be reset bullet
Spring, 7 for switch close to plate, 8 be the second spacer pin, 9 be mounting seat, 10 be optoelectronic switch, 11 be limiting plate, 12 be ratchet, 13

Specific embodiment
The present invention includes housing 2, it is characterised in that：Slide bar 3 is provided with housing 2, the surface of slide bar 3 is provided with ratchet 13；
The ratchet 12 with back-moving spring 6 is set corresponding to ratchet 13 in the housing 2；Mounting seat 9 is additionally provided with the housing 2,
Optoelectronic switch 10 is provided with mounting seat 9；The switch coordinated with optoelectronic switch 10 is provided with the slide bar 3 close to plate 7.
As a preferred embodiment of the present invention, thrust spring 4 is provided between the slide bar 3 and housing 2.
Used as another preferred scheme of the invention, the end of the slide bar 3 passes through mounting seat 9, and is provided with and installation
The limiting plate 11 that seat 9 is engaged.
The end of the slide bar 3 is stretched out outside housing 2, and is provided with connection ring 1.
Thrust spring 4 is provided with the first spacer pin 5 on the slide bar 3；Corresponding to switch close to plate 7 on slide bar 3
The second spacer pin 8 is provided with and mounting seat 9 between, the switch is arranged on the second alignment pin close to plate 7.
When the present invention is used, housing 2 is fixed to one end of crane 14, is then connected on slide bar 3 by a rope 15
Connection ring 1, the other end of rope 15 is connected with the other end of crane 14；When crane 14 because the reasons such as maloperation start
When, operating personnel only need to pull steel wire rope, and slide bar 3 drives switch close to plate 7 away from optoelectronic switch 10, optoelectronic switch
10 control crane 14 stopping actions；Now in the presence of ratchet 13, ratchet 12 and thrust spring 4, slide bar 3 is set to keep not
It is dynamic.After operating personnel confirm safety, ratchet 13, ratchet 12 are manually adjusted, then control the return of slide bar 3, make switch close to plate 7
Close to each other with optoelectronic switch 10, now crane 14 receives the signal of optoelectronic switch 10, can be again started up.
It is understood that above with respect to specific descriptions of the invention, being merely to illustrate the present invention and being not limited to this
Technical scheme described by inventive embodiments, it will be understood by those within the art that, still the present invention can be carried out
Modification or equivalent, to reach identical technique effect；As long as satisfaction use needs, all protection scope of the present invention it
It is interior.
