Abstract
Limit switch device includes casing, limit switch, horizontal pole, pivot, circular transmission seat, component and transmission wheel reset, pivot edge longitudinal extension and pin joint are in the casing, and outside the casing was extended to the upper end of pivot, the upper end of pivot was fixed in at the middle part of horizontal pole, and horizontal pole along horizontal extension, transmission seat and limit switch all are located the casing, and outside the pivot was located to the transmission seat cover, periphery along the radial sunken arc breach that forms of transmission seat, limit switch's transmission shaft can be followed horizontal flexiblely, and the arc breach of transmission is connected to transmission wheel pin joint in transmission shaft's end, the partial periphery of transmission wheel, restore to the throne component connection pivot and casing, the component that restores to the throne are used for driving the pivot and restoring to the throne when the external force release that acts on the horizontal pole. The utility model discloses in oversize vehicle the walking process, when the external component is touched to the horizontal pole, trigger limit switch promptly to send the signal that makes the oversize vehicle stop the walking, thereby reach anticollision function, but horizontal pole according to actual need possesses appointed length, the security is higher.
Description
Technical field
This utility model is related to a kind of limit switch device.
Background technology
Oversize vehicle is in the process of walking anticollision, often installs limit switches, when external member contacts limit switch
Testing agency such as cam or swing arm, that is, trigger limit switch, and then cause oversize vehicle to stop walking.Existing limit switch
Need that with external member close contact stopping action could being triggered, due to closer to the distance, limit switch exists and is damaged by collision
Risk, safety is low.
Utility model content
For the deficiencies in the prior art, this utility model is intended to provide and a kind of solve the spacing of above-mentioned technical problem and open
Close device.
For achieving the above object, this utility model is adopted the following technical scheme that：
A kind of limit switch device, it include housing, limit switch, cross bar, rotating shaft, circular transmission seat, reset element and
Transfer wheel；Rotating shaft is extended longitudinally and is articulated in housing, and the upper end of rotating shaft is extended outside housing, is fixed in the middle part of cross bar and is turned
The upper end of axle, and cross bar extends transversely；Transmission seat and limit switch are respectively positioned in housing, and transmission cover for seat is passed outside rotating shaft
The periphery for passing seat is radially recessed to form an arc notch, and the transmission axle of limit switch can transversely stretch, transfer wheel pivot joint
In transmission the tip of the axis, the arc notch of transfer wheel part-circular periphery face connection transmission seat；Reset element connection rotating shaft and housing, should
Reset element is used for when the external force for acting on cross bar discharges, and drives rotating shaft to reset.
Preferably, housing is externally provided with upper bearing (metal), and lower bearing is provided with housing, and rotating shaft is through upper bearing (metal) and lower bearing.
Preferably, reset element is the torsion spring being set in outside rotating shaft, and two ends of torsion spring are fixed in housing.
The beneficial effects of the utility model at least include：
When in oversize vehicle walking process, when cross bar touches external member, cross bar drives axis of rotation, and then drives
Transmission seat is rotated, and the arc notch for transmitting seat acts on transfer wheel, and then the transmission axle of limit switch is bounced back, and triggers spacing
Switch, to send the signal for making oversize vehicle stop walking, so as to reach collision prevention function, and because cross bar can be according to actual needs
Possesses designated length, safety is higher.When oversize vehicle leaves impact zone, i.e., when cross bar leaves external member, rotating shaft is resetting
Reset in the presence of element, so as to drive transmission seat to reset.
Description of the drawings
Fig. 1 is the structural representation of the better embodiment of this utility model limit switch device.
Fig. 2 is the structural representation of the subelement of the limit switch device of Fig. 1.
Specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, this utility model is described further：
Fig. 1 and Fig. 2 is referred to, this utility model is related to a kind of limit switch device, its better embodiment includes housing
70th, limit switch 30, cross bar 10, rotating shaft 40, circular transmission seat 60, reset element 50 and transfer wheel 32.
Rotating shaft 40 is extended longitudinally and is articulated in housing 70, and the upper end of rotating shaft 40 is extended outside housing 70, cross bar 10
The upper end of rotating shaft 40 is fixed at middle part, and cross bar 10 is extended transversely；Transmission seat 60 and limit switch 30 are respectively positioned in housing 70,
Transmission seat 60 is sheathed on outside rotating shaft 40, and the periphery for transmitting seat 60 is radially recessed to form an arc notch, limit switch 30
Transmission axle 31 can transversely stretch, and transfer wheel 32 is articulated in the end of transmission axle 31, the connection transmission of the part-circular periphery face of transfer wheel 32
The arc notch of seat 60；The connection rotating shaft 40 of reset element 50 and housing 70, the reset element 50 acts on cross bar 10 for working as
When external force discharges, rotating shaft 40 is driven to reset.
Thus, working as in oversize vehicle walking process, when cross bar 10 touches external member, cross bar 10 drives 40 turns of rotating shaft
It is dynamic, and then drive transmission seat 60 to rotate, the arc notch for transmitting seat 60 acts on transfer wheel 32, and then causes limit switch 30
Transmission axle 31 bounces back, and triggers limit switch 30, to send the signal for making oversize vehicle stop walking, so as to reach collision prevention function,
And because cross bar 10 can according to actual needs possess designated length, safety is higher.When oversize vehicle leaves impact zone, i.e. cross bar
10 when leaving external member, and rotating shaft 40 resets in the presence of reset element 50, so as to drive transmission seat 60 to reset.
Preferably, housing 70 is externally provided with upper bearing (metal) 21, housing 70 and is provided with lower bearing 22, and rotating shaft 40 passes through the He of upper bearing (metal) 21
Lower bearing 22, and then it is articulated in housing 70.
Preferably, reset element 50 is the torsion spring being set in outside rotating shaft, and two ends of torsion spring are fixed in housing 70.
For a person skilled in the art, technical scheme that can be as described above and design, make other each
Plant corresponding change and deform, and all these changes and deforms the guarantor that should all belong to this utility model claim
Within the scope of shield.
