Abstract
The utility model relates to a lifting limit switch used for vertical parking equipments. A fretting switch is arranged in a box body; the lower end of the box body passes the box walls and is provided with an oriented sleeve; a push rod is movably arranged in the oriented sleeve; the part of the push rod in the box body has a relatively thin concave past and a relatively thick convex part; the fretting switch and the push rod are arranged at a 90 degree angle; a power cutting switch is arranged on the push rod; The sealed box body enables that the lifting limit switch to work in a relatively stable environment, free from adverse environmental impact; the arrangement of the fretting switch and the power cutting switch actually provides double assurance and improves the reliability.
Description
Technical field
The utility model relates to a kind of lifting limit switch of three-dimensional parking device.
Technical background
Along with the raising of living standards of the people, the city is more and more crowded, and vehicle is more and more, and the price on parking stall is also more and more higher, and three-dimensional parking device can be parked more car amount with limited floor space.For safety, when car rises to highest point, need a limit switch control lifting device and stop.Existing three-dimensional parking device has the common travel switch of employing, and is simple in structure, easy to maintenance, be convenient to realize standardization, but because the operational environment of three-dimensional parking device is relatively poor, when particularly in the bigger environment of the temperature difference, using, travel switch freezes, and can influence the stability of its work.
Summary of the invention
The purpose of this utility model provides the lifting limit switch of the three-dimensional parking device of a kind of simple in structure, dependable performance, good stability.
For achieving the above object, the utility model adopts following technical scheme:
The lifting limit switch of three-dimensional parking device described in the utility model comprises sensitive switch, sensitive switch is installed in the box body, the lower end of box body is passed box wall fairlead is installed, the movable push rod of installing in the fairlead, the part that push rod is arranged in box body have thinner relatively recess and and thicker protuberance, sensitive switch and push rod are 90 degree angles installations.
The upper end of push rod be set with can relative motion recess, be connected with spring between recess and the push rod.
Power cut-out switch is installed above the push rod.
The utility model is installed in sensitive switch in the box body, and the box body of sealing can make it be operated in the metastable environment, exempts to be influenced by the adverse circumstances; Sensitive switch and power cut-out switch are set simultaneously, are actually and are provided with dual fail-safe, improved reliability.
Description of drawings
Accompanying drawing is the structural representation of an embodiment of the present utility model.
Embodiment
As shown in drawings, the lifting limit switch of three-dimensional parking device described in the utility model, comprise a sensitive switch and a power cut-out switch of being installed in the box body 5, and one passed box body 5 and be installed in push rod 13 below the box body 5, sensitive switch 10 is installed in a side of box body 5, the next door of push rod 13, is 90 degree angles with push rod 13 and installs.Power cut-out switch 101 be installed in box body 5 upper end, push rod 13 above, fairlead 12 passes the lower end that base plate is installed in box body 5, the movable push rod 13 of installing in the fairlead 12, the top of push rod 13 be set with can relative motion recess, be connected with spring between recess and the push rod 13.In order to make the spring location, the top of push rod 13 also is equipped with pusher bar support 8.
During use, the lifting limit switch of three-dimensional parking device is installed in the top of equipment, the recess respective side sensitive switch of push rod 13 at ordinary times, the top of push rod 13 does not contact power cut-out switch.When car rose to the extreme higher position, push rod 13 was touched on the top of car, and it is advanced box body 5, and push rod 13 compression sensitive switches 10 continued uply when sensitive switch 10 lost efficacy, and compression power cut-out switch 101 produces the protection action.After car left, push rod 13 is return under gravity and spring action, and sensitive switch returns to original state.
