Abstract
For a stop gear for building hoist, relate to building hoist.There is provided that structure is comparatively simple, safety a kind of stop gear for building hoist preferably.Be provided with limit switch, safe seat board, limit switch touching lever, limit switch contact and spacing striking plate; Limit switch touching lever one end is contained on limit switch, limit switch contact is located at the limit switch touching lever other end, limit switch is arranged on the safe seat board of construction elevator cage by bolt, along with construction elevator cage rising or when dropping to end position, the spacing striking plate of limit switch contact makes limit switch action, and cage is stopped.Limit switch directly can be in place and need not regulate, the limit switch touching lever that limit switch uses is cylindrical rod, not yielding, safe seat board need only be opened the circular hole that a spacing touching lever can pass, save overhours, improve the safety that building hoist uses.
Description
Technical field
The utility model relates to building hoist, especially relates to a kind of stop gear for building hoist.
Background technology
In order to ensure the safe operation of building hoist, be usually all provided with stop gear, but existing building hoist stop gear complex structure, safety is poor.Fig. 3 provides a kind of structure composition schematic diagram of existing building hoist limit switch.
Chinese patent CN203998498U discloses a kind of inhibiting device of building hoist, comprise being arranged on and drive on safety gear and the upper deceleration limit switch, upper limit position switch, lower deceleration limit switch, lower position switch, the interchange limit switch that are connected with the electric cabinet being arranged on cage indoor top respectively, and be arranged on the up spacing collision block on guide rail bracket top and the descending spacing collision block of guide rail bracket bottom; Up spacing collision block is provided with respectively side by side can with upper deceleration limit switch, upper limit position switch and exchange the upper deceleration limiting section of limit switch progressive contact, upper limit portion with on exchange limit portion, descending spacing collision block is provided with respectively side by side can with under subtract limit switch, lower position switch and exchange the lower deceleration limiting section of limit switch progressive contact, lower limit portion with under exchange limit portion.
Chinese patent CN103523630A discloses a kind of construction lifter cage roof fall safety caging device that can provide real-time anti-roof fall protection in standard knot supernumerary segment installation or removal process, comprise the limit switch be arranged on construction elevator cage, the control circuit that this limit switch is elevated drive motor with cage is electrically connected, and described limit switch is positioned at the top of cage and keeps certain diff-H with cage; During cage upward movement, synchronous upwards the sliding on building hoist standard knot leg surface and keep in touch with leg surface of contact of this limit switch, once the contact that cage rises to limit switch departs from column, limit switch is triggered and cutting-off controlling circuit, makes cage stop rising.
Summary of the invention
The purpose of this utility model is to provide that structure is comparatively simple, safety a kind of stop gear for building hoist preferably.
The utility model is provided with limit switch, safe seat board, limit switch touching lever, limit switch contact and spacing striking plate; Limit switch touching lever one end is contained on limit switch, limit switch contact is located at the limit switch touching lever other end, limit switch is arranged on the safe seat board of construction elevator cage by bolt, along with construction elevator cage rising or when dropping to end position, the spacing striking plate of limit switch contact makes limit switch action, and cage is stopped.
Limit switch can be made bound bit switch and use, and also can make deceleration limit switch and use.
Described limit switch touching lever can adopt cylindrical rod.
The utility model and the key distinction of existing limit switch are that limit switch touching lever is different, limit switch of the present utility model directly can be in place and need not regulate, the limit switch touching lever that limit switch uses is cylindrical rod, safe seat board need only be opened the circular hole that a spacing touching lever can pass, save overhours; And existing limit switch touching lever is strip plate, in use limit switch touching lever is easily out of shape, and touching lever position also will regulate after installing, safe seat board also must be opened strip hole to regulate for limit switch touching lever, affect the safety that building hoist uses, and existing limit switch touching lever is yielding, often will change, labor intensive material resources; And the spacing touching lever of limit switch of the present utility model to be cylindrical rod not yielding, and directly can be in place and need not regulate, use manpower and material resources sparingly, improve the safety that building hoist uses.
Accompanying drawing explanation
Fig. 1 is the structure composition schematic diagram of the utility model embodiment.
Fig. 2 is the structure composition schematic diagram of the utility model embodiment (not drawing safe seat board and spacing striking plate).
Fig. 3 is a kind of structure composition schematic diagram of existing building hoist limit switch.
Detailed description of the invention
See Fig. 1 and 2, the utility model embodiment is provided with limit switch 1, safe seat board 2, limit switch touching lever 3, limit switch contact 4 and spacing striking plate 5.Limit switch touching lever 3 one end is contained on limit switch 1, limit switch contact 4 is located at limit switch touching lever 3 other end, limit switch 1 is arranged on the safe seat board 2 of construction elevator cage by bolt, along with construction elevator cage rising or when dropping to end position, limit switch contact 4 contacts spacing striking plate 5 and makes limit switch 1 action, and cage is stopped.
Limit switch 1 can be made bound bit switch and use, and also can make deceleration limit switch and use.
Described limit switch touching lever 3 can adopt cylindrical rod.
