Description

The specialized equipment of elevator is installed

Technical field the utility model relates to a kind of equipment that elevator is used of installing.

Background technology is present, and the elevator in the domestic high-rise is installed no specialized equipment, is still the same construction method that adopts and build a building basically, promptly in the hoistway of every floor scaffold is set, and the workmen is operation on springboard.Its weak point is: scaffold is installed is wanted expensive manpower, financial resources and the time, people's operation on springboard is also dangerous simultaneously.

The summary of the invention the purpose of this utility model is to provide a kind of safe in utilization, easy accessibility, saves time, the specialized equipment of laborsaving, the installation elevator that saves money.

The utility model mainly includes sedan-chair frame, interim balance weight iron, towing machine and wirerope, and the elevator traction machine when wherein towing machine can be normal in the future the use also can be the towing machine of establishing in addition, and its available tower crane places it on the elevator top.Sagging with the supporting wirerope of this towing machine two ends on this towing machine, the one end links to each other with interim counterweight, and the other end is movably connected on the entablatrance of sedan-chair frame.Be preferably in that interim balance weight iron is other to be established two upper ends and be fixed on the fixed object of elevator top, the lower end is fixed on the vertical guiding steel wire on the fixed object of elevator bottom, establish the corresponding attaching parts that is enclosed within on the steel wire with it on the interim balance weight iron, it can make interim balance weight iron move up and down along the guiding steel wire.The sedan-chair frame mainly includes main frame and working frame, and wherein main frame is the vertical rectangular frame that is made of up and down two crossbeams and two root posts, and its crossbeam is the channel-section steel that the cross section is Ω shape, and the lower and upper cross-member opening is relative, and preferably column also is a channel-section steel.Their connecting portion of above-mentioned crossbeam and column sets up cooresponding through hole separately, by the bolt that passes both through holes they is flexibly connected.Respectively establish an orifice plate at the cross sill two ends, i.e. safety gear block, the movable safety tongs (the safety tongs structure of using with elevator is identical) that is connected with on it, the free end of two safety tongs lifting rods of interlock links to each other with the steel rope of velocity limiter.This velocity limiter (the velocity limiter structure of using with elevator is identical) part is fixed on the fixture of elevator top, and another part is fixed on the fixed object of elevator bottom.Be respectively equipped with in the outside of above-mentioned crossbeam two ends bottom land and lead the boots seat, be connected with sliding guide shoe (the sliding guide shoe structure of using with elevator is identical) on it, they are corresponding with the guide rail of elevator, are that main frame leads.Lead and establish the lower position switch that links to each other with the towing machine circuit on the boots for one therein, its sensor that protrudes upward can be corresponding with the elevator guide rail.Both sides at two flangings of above-mentioned every crossbeam are provided with through hole, be connected with a pair of perpendicular working frame horizon bar by fastener on it, the two ends of this a pair of horizon bar are fixed with another two ends to horizon bar again, four horizon bars are one group and constitute a underframe, so two groups of underframes on the last underbeam become the underframe up and down of working frame respectively.On four angles of above-mentioned two underframes, be respectively equipped with active connection, two underframes and four vertical rods flexibly connected by them.These four vertical rods upwards prolong as required, and every vertical rod can be one whole, also can be many and be linked to be one by active connection.Flexibly connect a horizontal cross bar by attaching parts in two adjacent vertical rods, co-altitude is established four, and the rectangular horizontal frame that they are formed is provided with flat board, i.e. service platform.Can establish 2-5 service platform as required in above-mentioned vertical rod from the bottom to top, they and underframe and vertical rod constitute working frame.Be the personnel on the assurance service platform and the safety of object, around each service platform, be provided with to protect and block.Be preferably in one of them vertical rod top and establish the upper limit position switch that links to each other with the towing machine circuit, its sensor protrudes upward, and can cut off the towing machine circuit automatically when touching the elevator top, makes the sedan-chair frame stop to rise.

It is roughly as follows to adopt the utility model that the operation of elevator is installed: at first on the elevator top, towing machine is installed, in the elevator bottom elevator first segment guide rail is installed afterwards, assemble the sedan-chair frame then, and make on it to lead boots corresponding with guide rail respectively.To be connected with interim balance weight iron around one end of the wirerope on the towing machine, the other end is connected with the sedan-chair frame, velocity limiter is loaded onto again, and promotes the sedan-chair frame with the towing machine that is located on the elevator item then again.People can be at some guide rails, balance weight iron slideway and other the relevant facility upwards installed successively on the service platform of sedan-chair frame more than second joint.Installing the sedan-chair frame transfers to elevator shaft bottom and dismantles.If towing machine is the towing machine of elevator, the wirerope that so only needs to link to each other with the sedan-chair frame is captiveed joint with lift car, and wirerope that will link to each other with interim balance weight iron and elevator counterweight iron phase connect again, elevator work is installed finishes substantially.Take place as accident, when the sedan-chair frame surpassed the specified speed of velocity limiter and descends, velocity limiter was just braked the steel rope on it, by coupled safety tongs pull bar again with the safety tongs braking, so the sedan-chair frame that connects together with safety tongs also is braked.The sedan-chair frame normally moves behind the trouble removal, velocity limiter and safety tongs recover normal working again, promptly order about the same with it moved further of steel rope of velocity limiter with the safety tongs of sedan-chair frame synchronization lifting, when the sensor of lower position switch contacts with guide rail in addition, the circuit of towing machine is connected, and sensor just can surmount the end top derailing that has installed guide rail when offside when misoperation rises the sedan-chair frame to be about to, and this moment, limiting device was can automatic cutout, cut off the towing machine circuit, the bridge frame just stops to rise.

The utility model has following advantage compared to existing technology:

1, the utility model is a kind of instrument character equipment, can be repeatedly used, and simple in structure, dismounting and carrying is all very convenient.

2, than existing scaffold mounting means

Save money: saved the labour cost of renting scaffold and carrying in large quantities;

Save time: saved the time of dismounting scaffold, improved the work efficiency that elevator is installed;

Laborsaving: as, to alleviate people's physical labor intensity without a dead lift scaffolding;

3, safety performance is good
