Description

A kind of drag device of household ladder
Technical field
This utility model relates to the technical field of elevator, particularly relates to the drag device of a kind of household ladder.
Background technology
Elevator is a kind of vertical conveyor with motor as power, equipped with box like gondola, for tier building take advantage of people or Carrying goods.Modem elevator mainly by traction system, guide rail, counterweight, safety device (as limiter of speed, safety tongs ease up Rush device etc.), signal manipulation system, the composition such as car and hall door.Wherein traction system is the core of elevator, major function It is output and transmission power, makes elevator run.Traction system is mainly by traction machine, traction steel-cable, directive wheel, crosshead sheave group Become.Elevator traction machine is the power-equipment of elevator, also known as elevator main, it by motor, brake, shaft coupling, reduction box, drag Running wheel, frame and the composition such as directive wheel and attached handwheel.
During elevator operation, in succession the counterweight on the crosshead sheave of car and counterweight respectively in traction steel-cable two ends, traction steel wire The mid portion of rope is wrapped on traction sheave and directive wheel, and directive wheel can ensure that car and counterweight are each transported along hoistway middle guide Going and do not contact, hoisting motor drives traction sheave to rotate, and car makes traction steel-cable be pressed on traction with the gravity of counterweight Frictional force is produced in race.By hoist ropes and the fricative pull strength of traction sheave, it is achieved car and the elevating movement of counterweight, i.e. Car rises, and counterweight declines, and counterweight rises, cage descending.Then, car along the upper and lower reciprocal operation of guide rail, reaches in hoistway Transport purpose.
The service requirement of elevator is safe and reliable, transfer efficiency is high, leveling accuracy and ride comfort etc., wants transfer efficiency Height, safety coefficient is high, then need the noise considering to lower traction machine and reduce vibration.Especially for present side Knapsack-rack knot Structure household ladder, owing to main guide rail and secondary guide rail are in side, can be fixedly installed to traction machine on main guide rail and secondary guide rail, traction The vibration that machine produces is conducted toward pit by main guide rail and secondary guide rail, and noise reduces.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above, it is provided that a kind of traction machine is arranged on be arranged on two main guide rails it Between support on the drag device of a kind of household ladder.
In order to solve the problems referred to above, technical solution adopted in the utility model is:
The drag device of a kind of household ladder, including the support being horizontally installed between two main guide rails and be fixedly mounted on Traction machine on support, described support includes main guide rail link, the horizontally set being symmetrically and fixedly mounted on two main guide rails Arrange below base of traction machine on two main guide rail links, main guide rail link and fix, with pair guide rail, the secondary guide rail being connected Link and base of traction machine side hard-wired counterweight fag end fixes seat, and described traction machine is fixedly mounted on traction On machine base.
It is fixedly welded with fixed plate on described base of traction machine, described fixed plate offers multiple installing hole, institute The traction machine stated is fixedly mounted in fixed plate by the bolt matched with installing hole.
Fix seat with counterweight fag end on described base of traction machine to threaded, described base of traction machine offers two Row installs counterweight fag end and fixes the screwed hole of seat.
Described base of traction machine is H profile steel, and described base of traction machine both sides are provided with reinforcing plate, described reinforcement Plate is fixedly welded on base of traction machine.
Described main guide rail link is C-type steel.
Described secondary guide rail link is L-type steel, a sidewall of described secondary guide rail link and the main guide rail of corresponding side Link is threaded, and another sidewall of described secondary guide rail link is threadeded with secondary guide rail.
Gain effect of the present utility model is:
Of the present utility model by being horizontally installed on the support between two main guide rails, traction machine is fixedly mounted on two and dominates On rail and two secondary guide rails, the vibration produced the when of so can being worked by traction machine is conducted by the secondary guide rail of two main guide rails and two To pit, make the lower noise of elevator, effectively raise transfer efficiency and the safety coefficient of elevator.
